BACKGROUND OF THE INVENTIONThe present invention is directed to an apparatus and method for applying labels to compact discs. More particularly, the present invention is directed to a label applicator apparatus and method for applying adhesive labels of varying shapes and sizes to compact discs that are cut into varying shapes and sizes. The invention can be used with compact disc recordables (CDRs), compact disc rewritables (CDRWs), compact disc read only memory (CD-ROMs), digital video discs (DVDs), digital video disc recordables (DVDRs), and digital video disc rewritables (DVDRWs).[0001]
In order to identify the content or nature of the information on a particular compact disc, compact disc manufacturers and owners typically apply identifying means to the compact disc. Marking with a writing instrument directly on a compact disc can damage the disc and is not feasible for the sale of commercial discs sold in large quantities. Thus, the preferred method in the industry for identifying the content of a compact disc is to apply an adhesive label with the identifying information to the disc. However, labeling of compact discs may be problematic if the label is affixed to or positioned on the disc improperly causing the disc to become physically unbalanced when it plays or reads and resulting in malfunctions to the disc or complete failure of the disc.[0002]
Known devices for applying labels to compact discs are typically designed for applying round labels to round compact discs only and are not designed for applying non-round labels to non-round compact discs. Thus, known devices that are capable of applying only round labels to only round compact discs have the disadvantage that they are limited in their applications.[0003]
In addition, these known devices have other disadvantages. A known device for applying labels to round compact discs is disclosed in U.S. Pat. No. 5,783,033 to Grossman. This patent discloses a device that uses a movable piston assembly to apply a label to a compact disc. However, a problem with the device of this patent is that the use of movable parts increases the complexity of the device and increases the costs of manufacturing the device. In addition, there are no positioning or retaining means for retaining the sides of the compact disc or the sides of the label in place as the label is being applied to the disc. This can result in movement of the disc or label during application of the label and can cause creases or air bubbles in the label or improper placement of the label on the compact disc, which can further result in malfunctions to the disc.[0004]
Another known label applicator is disclosed in French Patent No. 2763913. This patent discloses a device for adjusting and affixing an adhesive label onto a compact disc and includes a foam element inserted into a recessed portion of a circular base. However, a problem with the device of this patent is that the foam element is partially inserted in and affixed to the base and is not cut to be substantially the same size and shape as the label and compact disc, that is, it is in contact with only the center of the disc. The foam element in this patent is not removable, is not designed to facilitate a smooth and even application of the label to the compact disc, and is not designed to prevent or minimize the formation of air bubbles and creases that may form on the label during the application process. Such air bubbles and creases are not aesthetically pleasing and may cause balancing problems when the compact disc is played or read.[0005]
Accordingly, there is a need for a new and improved apparatus and method for applying labels to compact discs which overcomes and avoids the problems associated with known label applicators and methods.[0006]
SUMMARY OF THE INVENTIONThe present invention satisfies all of these needs as well as provides a unique and nonobvious apparatus and method for applying labels to shaped compact discs. None of the known label applicators and methods provides all of the numerous advantages of the present invention. It is an aspect of the present invention to provide an apparatus and method designed to apply both non-round and round labels of varying shapes and sizes to both non-round and round compact discs of varying shapes and sizes, i.e., shaped compact discs.[0007]
It is a further aspect of the present invention to provide an apparatus and method for applying labels to compact discs that requires no moving or electrical parts and thus decreases the costs of manufacturing and increases the simplicity of use and maintenance.[0008]
It is a further aspect of the present invention to provide an apparatus and method that is inexpensive and simple to manufacture, that is sturdy and not prone to damage in handling or use, that prevents damage to the compact disc, and that is manually operable and easy to use.[0009]
It is a further aspect of the present invention to provide an apparatus and method that includes positioning and retaining means for accurately aligning the label and the compact disc during label application and for securely retaining the compact disc in a substantially fixed position during label application to prevent or minimize the occurrence of creases in the label or improper application of the label.[0010]
It is a further aspect of the present invention to provide an apparatus and method that uses a deformable element to provide a smooth and even application of the label to the compact disc and that prevents or minimizes the occurrence of air bubbles in the label that may form during the application process and that prevents or minimizes improper application of the label.[0011]
It is a further aspect of the present invention to provide an apparatus and method that uses a deformable element that may be removed and replaced with a similar or different deformable element, for example, if the deformable element becomes worn out or a different size deformable element is desired.[0012]
It is a further aspect of the present invention to provide an apparatus and method that provides for easy removal and immediate use of the compact disc after it is labeled.[0013]
An apparatus for applying a label to a compact disc is disclosed. The apparatus comprises a base having a top surface and a bottom surface. The apparatus further comprises a rod having a top end, a bottom end, and a side, wherein the bottom end of the rod is coupled to a center portion on the top surface of the base so that the rod protrudes upwardly from the base. The apparatus further comprises at least two positioning members each having an outer surface, an inner surface, a top end, and a bottom end. The bottom end of each of the positioning members is coupled to the top surface of the base so that the positioning members protrude upwardly from the base and are spaced apart from each other on each side of the rod. The positioning members are adapted to position and retain the label and the compact disc in place between the positioning members. The apparatus further comprises a deformable element having a center aperture, a raised top surface, and a substantially flat bottom surface, wherein the center aperture of the deformable element is adapted to fit over the rod and the deformable element is adapted to fit between and adjacent to the positioning members. The shape and configuration of the deformable element facilitates the smooth and even application of the label to the compact disc when the label is applied to the compact disc.[0014]
In one version of the present invention, the deformable element, the label, and the compact disc are all substantially rectangular in shape, that is, for purposes of the present invention, in the shape of a compact disc business card. The substantially rectangular shape has a first pair of opposite sides that are substantially straight and a second pair of opposite sides that are curved outwardly. In other versions of the present invention, the deformable element, the label, and the compact disc may be rectangular in shape, square in shape, of a miniature round shape, or various other shapes and configurations. In all of the versions of the present invention, the top surface of the deformable element, no matter what the shape, has a raised portion that facilitates the smooth, even application of the label to the compact disc when the compact disc is pressed against the label and is pressed against the deformable element.[0015]
A method is also disclosed for applying a label, preferably having an adhesive side and a nonadhesive side, to a compact disc having a first side which is the printable and nonreadable side and a second side which is the recording and readable side. The method comprises the steps of: providing the apparatus of the present invention; aligning the label having a center aperture over the deformable element so that the label and the deformable element are in parallel alignment; placing the center aperture of the label over the rod and positioning the label over the deformable element and between the positioning members so that the nonadhesive side of the label is in contact with the raised central portion of the top surface of the deformable element and the adhesive side of the label faces upward; aligning the compact disc having a center aperture over the label so that the compact disc and the label are in parallel alignment; placing the center aperture of the compact disc over the rod and positioning the compact disc over the label and between the positioning members so that the first side of the compact disc is in contact with the adhesive side of the label and the second side of the compact disc faces upward; pressing the positioned compact disc against the adhesive surface of the label and against the deformable element, such that the deformable element compresses from a center curved portion outwardly to its end portions and causes the label to adhere to the compact disc in a smooth, even motion giving the label a smooth, even appearance on the compact disc; and, removing the labeled compact disc from the apparatus.[0016]

Preferably, thepositioning members28 are each spaced an equal distance from therod20, as well as each spaced an equal distance from an imaginary vertical axis (not shown) down the center of thebase12. Preferably, thepositioning members28 are spaced an equal distance from therod20 in the range of from about 1.0 inch to about 2.5 inches. Preferably, thepositioning members28 are of a shape such that the bottom portion is wider than the top portion, as shown in FIG. 1. However, the positioning members may also be formed in other suitable shapes and sizes. Preferably, thepositioning members28 each have a height in the range of from about ¾ inch to about 2.0 inches. Preferably thepositioning members28 each have a width in the range from about 1.0 inch to about 2.0 inches. Preferably thepositioning members28 each have a top thickness in the range from about {fraction (1/16)} inch to about ¼ inch. Preferably thepositioning members28 each have a bottom thickness in the range from about ¼ inch to about ½ inch Thepositioning members28 are preferably solid and are comprised of plastic, wood, metal or another suitable material. More preferably, thepositioning members28 are comprised of a rigid, sturdy plastic material, such as polypropylene. The plastic material for the positioning members is available from the same manufacturer as discussed above with respect to the base.
While the[0030]rod20 andpositioning members28 may be coupled to thetop surface14 of the base12 by adhesive, screw means, or other suitable attachment means, for ease of manufacturing and strength, thebase12,rod20, andpositioning members28 are preferably formed in one unitary piece, such as by single cavity injection molding.
As shown in FIG. 1, the[0031]apparatus10 further comprises adeformable element40. Thedeformable element40 may be comprised of foam or another suitable cushioned material. Preferably, thedeformable element40 is comprised of a polyurethane foam which may be shaped to fit theapparatus10 by die-cutting a foam sheet in substantially the same shape as the shape of the desired label and/or shape of the desired compact disc. However, other suitable fabrication methods and equivalent materials may be used. The polyurethane foam material for the deformable element is available as 33100 polyurethane from Wasatch Container, Inc. of Salt Lake City, Utah. This material used with the present invention provides such advantages such as lower manufacturing costs and simple fabrication. The thickness of the foam used to make the deformable element is preferably between about ⅛ inch to about 1¾ inches.
As shown in FIGS.[0032]1-5, thedeformable element40 of this version comprises atop surface42, a bottom surface44, and sides46. In this version, thesides46a,46bcomprise two substantially straight sides46aopposite each other, and two slightlycurved sides46bopposite each other, wherein thesides46bcurve slightly outwardly. Preferably, sides46ahave a length in the range of from about 1.5 inches to about 5.0 inches. Preferably, sides46bhave a length in the range of from about 1.5 inches to about 6.0 inches. In this version, preferably, thetop surface42 of thedeformable element40 is raised upwardly in a raisedcentral portion48. The raisedcentral portion48 preferably has a curved configuration or an angled configuration. However, other suitable configurations may also be contemplated.Top end portions50 of thetop surface42 are preferably lower in height than the height of the raisedcentral portion48, that is, the top surface gradually increases in height from theend portions50 to the raisedcentral portion48 and peaks in height at the raisedcentral portion48. Preferably, the thickness of thedeformable element40 at theend portions50 is in the range of from about ⅛ inch to about 1⅝ inch. Preferably, the thickness of the deformable element at the raisedcentral portion48 is in the range of from about ¼ inch to about 1¾ inches. Preferably, the bottom surface44 of thedeformable element40 is substantially planar or flat.
The[0033]deformable element40 further comprises anaperture52. Preferably, theaperture52 is substantially round in shape and formed in the center of thedeformable element40. Theaperture52 is adapted to receive therod20. Theaperture52 of the deformable element has a diameter that is slightly greater than the outer diameter of the rod. Thus, when thedeformable element40 is fitted over therod20, the deformable element is preferably of a size and shape that creates a snug fit over the outer surface of the rod, with the bottom surface44 of thedeformable element40 against thetop surface14 of the base, and with thesides46aof thedeformable element40 fitted between and adjacent to or against theinner surfaces32 of thepositioning members28. Theinner surfaces32 of thepositioning members28 are preferably in parallel alignment with thesides46aof thedeformable element40. Theinner surfaces32 of thepositioning members28 act as areas of retention for securing or retaining thedeformable element40, alabel54, andcompact disc56 in a substantially fixed position when such label and compact disc are positioned over thedeformable element40 and over therod20 during the labeling process. Thepositioning members28 are used to facilitate alignment and positioning of thelabel54 with thedeformable element40. In addition, thepositioning members28 are used to facilitate the alignment and positioning of thecompact disc56 with thelabel54 and thedeformable element40. Thepositioning members28 are spaced apart from each other at a distance slightly greater than the width of thedeformable element40, slightly greater than the width of thelabel54, and slightly greater than the width of thecompact disc56.
The raised configuration of the top surface of the deformable element is advantageously used to apply the label to the compact disc from the center outwardly to the ends, allowing for a smoother, more even label application. In addition, the apparatus of the present invention prevents or minimizes the occurrence of air bubbles under the label, the occurrence of creases in the label, and the improper placement of the label on the compact disc which can result in malfunctions to the disc or failure of the disc.[0034]
The[0035]deformable element40 may be removable or affixed to thebase12 via an adhesive material or another suitable attachment means. Preferably, thedeformable element40 is removable. If the deformable element becomes worn out, it is possible with the present invention to remove the worn deformable element and replace it with a new deformable element of the same size and shape. In addition, if it is desired to label a different shaped compact disc, it is possible to remove the deformable element and replace it with a deformable element of a different size and shape. For both ease of manufacture and aesthetic purposes, the shape of the deformable element preferably mirrors the shape of the compact disc and label.
As shown in FIG. 1, the[0036]deformable element40 is cut in substantially the same size and shape as thecompact disc56 for which thelabel54 is to be applied to. In the version shown in FIG. 1, thedeformable element40 is of substantially the same size and shape as thecompact disc56, which for purposes of this invention, has the shape and configuration of a compact disc business card. As shown in FIG. 1, thedeformable element40, thelabel54, and thecompact disc56 are all substantially rectangular in shape.Sides46aof thedeformable element40 are both substantially straight.Sides46bof thedeformable element40 are slightly curved outwardly. As shown in FIG. 1, the shape and configuration of both the label and compact disc substantially mirror the shape and configuration of the deformable element.
FIG. 2 shows a top plan view of the label applicator apparatus of FIG. 1. FIG. 3 shows a cross-sectional view of the label applicator in the direction of line[0037]3-3 of FIG. 2, as thecompact disc56 is pressed downwardly against thelabel54 and thedeformable element40. FIG. 4 shows a cross-sectional view of the label applicator in progression from FIG. 3, where thecompact disc56 is completely pressed against thelabel54 and thedeformable element40 is compressed. FIG. 5 shows a cross-sectional view of the label applicator in the direction of line5-5 of FIG. 2.
FIGS.[0038]6-8 show other versions of the present invention. FIG. 6 is an exploded view of another version of alabel applicator200 of the present invention where a shapedcompact disc202, alabel204, and adeformable element206 are all in the shape of a rectangle. The top surface of thedeformable element206 is raised in the central portion.
FIG. 7 is an exploded view of another version of a[0039]label applicator300 of the present invention where a shapedcompact disc302, alabel304, and adeformable element306 are all in the shape of a square. The top surface of thedeformable element306 is raised in the central portion.
FIG. 8 is an exploded view of another version of a[0040]label applicator400 of the present invention where a shapedcompact disc402, alabel404, and adeformable element406 are all in a miniature round shape. This miniature round shape is smaller than the shape of a conventional round compact disc. The top surface of thedeformable element406 is raised in the central portion.
It is also contemplated that the apparatus of the present invention can be designed to include a deformable element that conforms to numerous other shapes and configurations of the label and the shaped compact discs. In all of the versions of the present invention, the deformable element, no matter what the shape, has a portion of the top surface, preferably the central portion, that is raised and that facilitates the smooth, even application of the label to the compact disc when the compact disc is pressed against the label and, in turn, pressed against the deformable element.[0041]
The present invention is also directed to a method for applying a label to a compact disc using the[0042]apparatus10 of the present invention described previously. The method according to the present invention is suitable for applying labels of varying shapes and sizes to compact discs of varying shapes and sizes. The method is used for applying a label, preferably having an adhesive side and a nonadhesive side, to a compact disc having a first side a first side which is the printable and nonreadable side and a second side which is the recording and readable side Preferably, the method is performed manually.
For convenience, referring to FIG. 1, the method comprises the steps of first providing the[0043]apparatus10, or any other versions of the apparatus, of the present invention and aligning thelabel54 having acenter aperture58 over thedeformable element40 so that thelabel54 and thedeformable element40 are in parallel alignment with the label over the deformable element. Preferably, the deformable element is adjacent to and between theinner surfaces32 of thepositioning members28.
Typically, self-adhesive labels have wax paper over the adhesive side of the label. Before the label is applied, the wax paper backing of the self-adhesive label is removed. The next step of the method is placing the[0044]center aperture58 of thelabel54 over and around therod20 and positioning and moving thelabel54 downwardly toward thedeformable element40, so that anonadhesive side60 of thelabel54 is in contact with and rests on a portion of thetop surface42 of thedeformable element40, and anadhesive side62 of thelabel54 faces upward. The inner diameter of thecenter aperture58 of the label is greater than the outer diameter of therod20. In this position, therod20 protrudes upwardly through thecenter aperture58 of thelabel54. Preferably, a portion of each of thesides64 oflabel54 is adjacent to theinner surfaces32 and the label is positioned and retained between theinner surfaces32 of thepositioning members28. Because the label is fitted over therod20 and retained between the positioningmembers28, movement or slippage of the label is prevented or minimized, and there is also little opportunity for the label to curl.
The next step of the method is aligning the[0045]compact disc56 having acenter aperture66 over thelabel54, so that the compact disc and the label are in parallel alignment with the compact disc over the label. The next step of the method is placing thecenter aperture66 of thecompact disc56 over therod20 and positioning thecompact disc56 over thelabel54 so that afirst side68 of the compact disc is in contact with theadhesive side62 of the label and asecond side70 of the compact disc faces upward with protruding ridges on the second side facing upward. The inner diameter of thecenter aperture66 of the compact disc is greater than the outer diameter of therod20. In this position, therod20 protrudes upwardly through thecenter aperture66 of thecompact disc56. Preferably, a portion of each of thesides72 ofcompact disc56 is adjacent to theinner surfaces32 and the compact disc is positioned and retained between theinner surfaces32 of thepositioning members28. Because the compact disc is fitted over therod20 and retained between the positioningmembers28, movement or slippage of the compact disc is prevented or minimized, and there is also little opportunity for the compact disc to be damaged. Thecenter aperture58 of thelabel54 can be slightly larger or the same size as thecenter aperture66 of the compact disc.
The next step in the method is pressing the positioned[0046]compact disc56 against theadhesive surface62 of thelabel54 and against thedeformable element40, such that the deformable element deforms or compresses from the central raisedportion48 outwardly to endportions50 and causes thelabel54 to adhere to thecompact disc56. Preferably, the pressure is manual pressure. The pressure to the disc is applied in a smooth, even motion in order to minimize the occurrence of air bubbles between the label and the compact disc and in order to minimize the occurrence of creases in the label. Preferably, the compact disc is manually depressed onto the adhesive surface of the label and pressed out evenly over the label and over the deformable element. Preferably, the pressing should be done slowly in a smooth, fluid motion that keeps the compact disc as flat as possible. As the compact disc slides down the rod, it will make contact with the raised center portion of the label first. In a smooth motion, downward pressure is applied to the compact disc allowing it to slowly compress the deformable element. As the bottom ends74 of the compact disc are pressed over thetop end portions50 of the deformable element, the label is applied with the no or minimal air bubbles and creases. The smooth, even motion gives the label a smooth, even appearance on the compact disc. Thus, the method of the present invention prevents or minimizes the occurrence of air bubbles that may form during the application process, prevents or minimizes the occurrence of creases in the label that may be created during the application process, and prevents or minimizes the improper application of the label to the compact disc during the application process. The label may extend to almost the outer edge of the disc or may be of a substantially smaller diameter than the disc. The final step is removing the labeled compact disc from the apparatus. As the compact disc is lifted off of the deformable element, the deformable element, which is in a compressed state, expands and raises back to its original decompressed state, and the apparatus is ready for use again.
Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions of the invention are possible. Therefore, the scope of the appended claims should not be limited to the description of the preferred versions contained herein.[0047]
