United States Patent 3,287,075 PACKAGE AND CABINET UNIT Leonard A. Batke, Somerville, and Cleon E. Hammond,

Hopewell, NJ., assignors to Ethicon, Inc., a corporation of New Jersey Filed Dec. 12, 1962, Ser. No. 244,112 7 Claims. (Cl. 312-108) The present invention contemplates a package and cabinet unit which is adapted to be used both as a package and as a part, or unit, of a cabinet formed by assembling several of these units for storing and dispensing their contents. The package and cabinet unit of this invention is particularly adapted for use with products which it is desirable to store and dispense in a number of types or sizes in or from a cabinet formed from the original packages in which the products were shipped without the need for first removing the products from the packages. Thus, this unit is particularly adapted for packaging, storing and dispensing suture items. However, as described hereinafter, a variety of other products may be packaged and dispensed in and from this unit.

The package and cabinet unit of this invention comprises a rectangular dispensing drawer normally open at the top for dispensing the items it contains, and a rectangular sleeve for receiving the drawer. The sleeve has a rectangular cross section approximately the same as that of the drawer, although slightly larger in dimension so that the drawer fits in the sleeve and may be moved back and forth slideably therein. The sleeve comprises a plurality of fold-out tabs and a corresponding plurality of positioning slots, and the tabs and slots are located with respect to one another so that adjacent sleeves may be connected to one another to form a cabinet by inserting the tabs of one sleeve into the slots of another. Normally the front end of the sleeve is open to permit the drawer to be inserted therein and removed therefrom and the back end of the sleeve is closed to help protect the contents of the drawer and to provide a back surface for the cabinet. end of the dispensing drawer is marked with appropriate indicia to indicate the contents of each unit. Thus, when adjacent units are connected to form a cabinet the contents of each drawer in the cabinet may be determined from a quick inspection of the front of the cabinet.

The fold-out tabs are detachably held flat in or against The outside of the front the sides of the sleeve during shipping and prior to assembly of the units to form the cabinet. For instance, each tab may be stamped out of packaging board forming one of the sides of the sleeve except for a permanent connection defining a fold-line with the side of the sleeve and may be retained .fiat, in the side of the sleeve from which it is stamped, by thin strips or nibs which are not cut during the stamping operation. When it is desired to use the tabs for assembling the unit, it is only necessary to break the nibs and fold the tabs down or out away from the sides of the sleeve about the foldlines so that they may be inserted in corresponding slots in an adjacent unit. It is preferred that at least one of the fold-out tabs protruding from each sleeve extends vertically when folded out in operative position to engage a corresponding slot in a like unit above or below the sleeve, and at least one of the fold-out tabs extends horizontally when in operative position to engage a like unit alongside said sleeve. The tabs and slots are positioned at the corners of the sleeve so that the drawers of individual cabinet units may be inserted and withdrawn either partially or completely in and from the unit any number of times without being blocked by the tabs. When the phrase corner of the sleeve is used herein, it shall mean approximately along the line of juncture 3,287,075 Patented Nov. 22, 1966 "ice between a horizontal and vertical side wall of the sleeve at a corresponding longitudinal corner edge of the sleeve.

It also is preferred that all tabs, other than those located at the rear of the sleeve, be located at the front of the sleeve so as to minimize the likelihood of the tabs protruding inside the sleeve in such a way as to interfere with movement of the drawer therein. It is another preferred feature of this invention that the edges of the tabs be curved or inclined in such a way that when the drawer is inserted in the sleeve, a cam action occurs between the rear of the drawer and the edges of the tabs which presses the tabs against the side of the sleeve and thereby obviates any possibility of interference between the tabs and the drawer. As a further feature, fold-in tabs are provided opposite one another in the sides of the drawer to provide dividers which help maintain envelopes contained therein upright and in position in the drawers. A pull-out tab integral with the drawer also may be provided to facilitate withdrawal of the drawer from the sleeve.

It is an important advantage of this invention that both the sleeve and the drawer of the package and cabinet unit may be stamped from a single sheet of inexpensive, relatively stiff and foldable packaging board and then appropriately folded and marked to form the sleeve or drawer as the case may be. The folded parts of the sleeve or drawer may be held in position by an adhesive of the type normally used for this purpose appropriately placed in a conventional manner. Indicia andother markings may be stamped directly on the packaging board. However, if desired, suitable marking paper or labels may be applied thereto for this purpose.

It is highly advantageous that each of the package and cabinet units be interchangeable in construction so that they may be arranged with respect to one another as desired in assembling the cabinet. Since different customers will order different types and sizes of products and will want them arranged differently in the cabinet, it is almost impossible for the manufacturer to predict in advance how the cabinet units will be assembled with respect to one another and normally necessitates interchangeability of the units for forming the cabinet.

Other advantages of this invention will be apparent from the following description and claims taken together with the drawings wherein:

FIG; 11 is a view in elevation showing the same tab after it is inserted in the-said cooperating slot.

Referring to FIGS. 1-9 of the drawings, there is shown a package andcabinet unit 21 and a correspondingselfsupporting cabinet 22 according to a preferred embodiadapted to be inserted in and withdrawn from the open front end of the sleeve. Thesleeve 23 comprises a plurality of fold-out tabs and a corresponding plurality of positioning slots located in the sleeve in such a way that a plurality of units comprising these sleeves may be joined with one another to arrange theirdrawers 26 in vertical and horizontal rows and form thesuture cabinet 22 by inserting the tabs of one sleeve into the slots of another.

It is an important feature of this invention that both thesleeve 23 and thedispensing drawer 26 of the unit may be formed from conventional paper packaging board. This inexpensive, relatively stifi and foldable paper board, normally called boxboard, may be cut and folded with ease to form the necessary parts. In fact, both the sleeve and the drawer, individually, may be cut and folded from a single sheet of packaging board in accordance with this embodiment.

Thedispensing drawer 26 normally is open at the top, as shown in FIGS. 3 and 8, to allow the insertion and removal of suture items therefrom and isclosed at'the top by insertion of the drawer in thesleeve 23, as shown in FIG. 1. The drawer comprises ahorizontal bottom wall 27 formed by folding and overlapping several parts, and oppositevertical side walls 28 connected by afront end wall 29 and arear'end wall 31. The parts making up thebottom wall 27 of the drawer are integral with respective portions of some or all of the side .and end walls thereof, Thefront wall 29 of the drawer presentsindicia 32 on its front surface which describe fully the contents of thedrawer, and a pull-out tab ,33 to facilitate withdrawal of the drawer from the cabinet. The manufacturer assembles thedrawer 26, marks the front of itwithappropriate indicia 32, as described above, packs the drawer with the proper suture items, and then inserts thedrawer 26 into asleeve 23 to form the suture package and cabinet .unit. This unit may be shipped as is or overwrapped with cellophane *or the like to hold the parts together and provide a dust cover. Normally several units are packed together in a carton for shipment and they may be retained in the carton until they are needed for assembly of the suture cabinet.

Thedispensing drawer 26 is particularly adapted for storing and dispensing suture items contained in hermetically sealed, interiorly sterilizedenvelopes 35. Typically, approximately three dozen 'envelopes 35, stand ing upright and extending transversely between the side the drawer; Each of thedividers 36 is folded inwardly from one of theside walls 28 and is formed by partially cutting the side walls to define three of its edges; .The

divider 36 remains foldably connected to the sidewallalong one edge and the uncut portions along the other edges are adapted to be broken by finger pressure as the drawer is being packed to allow the dividers to be folded toward one another. arranged in three pairs, spaced longitudinally. along the side walls of the drawer, theenvelopes 35 containing the 'suture items will be retained in the drawer in four groups located in the four spaces defined by the three pairs of dividers and the front andrear walls 29 and 31 of the drawer. Thus, theenvelopes will remain substantially upright until the last is removed from the rawer, thereby facilitating the grasping of the envelopes and their rapid removal from the cabinet when neededv during an operating room emergency.

The pull-outtab 33 at the front of the drawer also.

is only. partially cut from the front wall of the drawer by the manufacturer so that it'does not protrudelfrom the unit during shipment and handling prior to use.

Again, when it is desired to withdraw the drawer from the sleeve, thetab 33 is fully broken from the front wall of the drawer along its curved top edge and folded out for gripping as shown in FIGS. 3 and 8. Also, as shown in these figures, a vertical tab or cover 37 is provided in the folded structure of the drawer behind the withdrawal tab so that when the withdrawal tab is folded out for use,

the hole formed by its removal is blocked by the cover.

slightly larger than that of thedrawer 26 and is adapted to receive the drawer slidably therein in such a way that the drawer may be inserted in the sleeve to fully enclose its contents and withdrawn at least partially therefrom to provide access to its contents. As mentioned above, thesleeve 23 possesses a plurality of fold-out tabs and a corresponding plurality of positioning slots for connecting it with like sleeves of like units to form thesuture cabinet 22. Thesleeve 23 comprises abottom wall 38,

atop wall 39,side walls 40, and arear wall 30, which closes therearend 25 of the sleeve. The tabs are. connected to thebottom wall 38 of the sleeve and, the slots are presented at thetop wall 39 thereof. presents two vertical side tabs'41 and 42 and onehorizontal side tab 43, as well as one verticalrear tab 44. The words vertical and horizontal, as used to describe the tabs, refer to their folded out, or operative, positions. The fold-out tabs are formed by partially. stamping,.or

cutting out, the out-lines of the tabs from thebottom wall 38 of the sleeve and leaving the tabs uncut and attached to thebottom of the sleeve along folding edges' which correspond with the side edges 45 and rear edges Thetabs 41, 42 and 44 l 46 of the bottom of the sleeve. are partially cut from the bottom 38 of the sleeve only in that they are still retained in position in the bottom of the sleeve by thin strips, or nibs, 47,which are not severed during the stamping operation. Thesenibs 47 hold the tabs flat and in position in the bottom of the sleeve during shipping and prior toassembly of the units to form the cabinet. However, when it is desired to assemble these sleeves, the tabs may be folded out easily into operative position merely by pulling or pushing thetabs with respect to the bottom of the sleeve to break the nibs. Radial cuts 50, such as shown in FIGS. 4 and 5, may be provided to facilitate displacing the bottom 38 of the sleeve from the outside of the unit to grip the tabs and fold them into operative position. Correspondingslots 48 for cooperating with thevertical tabs 41, 42 and 44 are cut along the side edges of thetop wall 39 of the sleeve,

Since thedividers 36 arev Each sleeve where it joins theside walls 40 thereof, and along the rear edge of the sleeve where it joins therear wall 30 thereof. Thus, when the threevertical tabs 41, 42 and 44 are folded downwardly into operative position, the sleeve may be assembled with a like sleeve positioned below merely by inserting the tabs into the corresponding threeslots 48 in the lower sleeve as illustrated in FIG. 6.

Thehorizontal side tab 43 is partially cut out of thevertical side tab 41 and has a common folding edge therewith by which it remains connected to the bottom 38 and theadjacent side walls 40 of the sleeve. Thehorizontal tab 43 is considerably smaller than thevertical tab 41 from which it is cut and a correspondingly smaller, or shorter,slot 49 is provided along the opposite bottom side edge of thesleeve 23 for cooperating with thehorizontal tab 43 of an adjacent unit.

As shown most clearly in FIGS. 6 and 7, theside tab 43, after insertion in theside slot 49 in an adjacent unit, falls within thespace 51 formerly occupied by thevertical side tab 42 at this edge of the adjacent unit. Since thetab 43 is folded outwardly from thebottom wall 38 of the sleeve in which it was originally located by approximately 180", it has a tendency to return toward its original position and therefore to move downwardly into and through the space, orhole 51, left by the above mentioned vertical side tab. Thus, theside tab 43 presses downwardly upon thetop wall 39 of the sleeve below theopening 51 as shown most clearly in FIG. 7. Also as shown in FIG. 7, if the sleeves to be joined are in the bottom horizontal row of units, theside tab 43 presses downwardly upon the top of the vertical side tab which has not been removed from its original position in the adjacent unit.

As shown most clearly in FIGS. 7-9, thevertical side tabs 41 and 42 extend downwardly into the sleeves assembled below them in the suture cabinet and tend to remain extending downwardly and inwardly at a slight angle due to the location of theside walls 40 below theside slots 48. Thevertical side tabs 41 and 42 present inclined curvedbottom edges 52 which are adapted to provide a cam action with the rear 31 of thedrawer 26 as it is inserted in thesleeve 23 so that movement of the drawer into contact with the inclinedcurved edges 52 presses theside tabs 41 and 42 against the inside surfaces of theside walls 40 of the sleeve and out of the way of the drawer. Referring in particular to FIGS. 7, 8, and 9, it will be seen that the rear corner 53 of the drawer at one side of theunit first contacts the inclinedcurved edge 52 of theside tab 42 adjacent the top of thetab 42 and just below theslot 48 in the top corner of the sleeve. At theslot 48 thetab 42 is positioned partially in line with theside wall 40 of the sleeve defining this slot and the above-referred-to rear corner 53 of the drawer first strikes theinclined edge 52 of the tab at a point where thetab 42 is virtually in contact with theadjacent side wall 40 of the sleeve definingthe slot, as shown in FIG. 9. Thus, there is room for the above-referred-to corner 53 of the drawer to pass behind, or over, the leadingend 54 of the tab. As thedrawer 26 moves further into thesleeve 23 it will continue to travel over the remainder of theinclined cam edge 52 of the tab and press, or swing, thewhole tab 42 into a substantially vertical position along theside wall 40 of the sleeve.

The above described cam action is facilitated by shoulders 55 provided on the inside surfaces of theopposite side walls 40 of the sleeve at thefront end 24 of the sleeve. These shoulders 55 are formed by folding the sheet material, from which the sheet is made, back upon itself to form arim 56 of double thickness. As shown most clearly in FIG. 8, thisrim 56 extends all around the front end, ormouth 24, of the sleeve, not only along the side surfaces of its side walls. Thus, the shoulders 55 provided by the rim56 are of double thickness and are located just ahead, or in front, of theleading end 54 of the adjacentvertical side tabs 42 extending into the sleeve from the unit above.

6 The transverse distance between these shoulders 55 is slightly greater than the transverse width of thedispensing drawer 26 in order to allow the drawer to be inserted into thesleeve 23 between the shoulders. Thus, the shoulders 55 act to space the sides of thedrawer 26 from the sides of thesleeve 23 by an amount approximately equal to the thickness of thetabs 41 and 42, which in turn are as thick as the sheet material from which the sleeve is made. As shown most clearly in FIG. 9, this relationship between theside 28 of thedrawer 26, the shoulder 55, and thevertical side tab 42, in effect, recesses thefront end 54 of the side tab behind the shoulder SS'and assures that the adjacent rear corner 53 of the dispensing drawer first will contact theinclined edge 52 of thetab 42 beyond thefront end 54 of the tab to facilitate swinging the tab against the side wall as described hereinbefore.

As mentioned hereinbefore, the verticalrear tab 44 fits into acorresponding slot 48 located in the top rear edge of the sleeve below. Therear wall 30 of the sleeve is formed by folding various parts together, as shown most clearly in FIG. 5. These parts are in the form of flaps which, prior to folding, extend rearwardly from the respective top, bottom, and side walls of the sleeve. These flaps are so shaped that when folded together they provide arecess 57 in therear wall 30 of the sleeve for receiving thevertical end tab 44 from the unit above, after it is inserted through the end slot in the sleeve. This facilitates insertion of therear tab 44 through the rear slot and prevents the rear tab from passing inwardly over therear wall 30 of the sleeve and then climbing over therear wall 31 of thedispensing drawer 26 located in the sleeve to protrude downwardly into the rear of the drawer. Of course, if, in assembling the units, therear tab 44 were to pass into the drawer of one of the units, it would tend to prevent that drawer from being withdrawn from the sleeve, especially if the drawer were tightly packed with suture envelopes.

FIGS. 10 and 11 illustrate the way in which the fold-out tabs of one sleeve fit into and cooperate with the cooperating slots of another sleeve for holding the sleeves firmly together. One sleeve is positioned above the other with one of thevertical side tabs 42 folded out so as to extend approximately parallel to theside wall 40 of the sleeve to which it is attached and the tab is located directly above the corresponding cooperatingslot 48 in the sleeve below. For purposes of illustration, thetab 42, shown, may be described as a first fold-out tab, foldably connected to a first corner 101 of the top sleeve, and the cooperatingslot 48 may be referred to as located in a second corner 102 of the sleeve below. When the sleeves are formed from foldable sheet material, such as conventional paperboard, the first and second corners of the said sleeves normally would be formed by folds in the sheet material extending longitudinally of the sleeve. In assembling the sleeves to form a cabinet according to this invention, the fold-outtab 42 is adapted to be inserted in the cooperatingslot 48 in such a way that the sleeves are held firmly together by the fit of the tab in the slot.

The cooperatingslot 48 comprises an opening, or slit, 103 in the second corner 102 of the bottom sleeve. Theopening 103 extends longitudinally of the corner and, when the corner 102 is formed by folding sheet material as referred to above, theopening 103 is located in, and extends longitudinally along, the fold forming the corner. The cooperatingslot 48 also comprises a pair ofcuts 104; one of which is connected to each end of theopening 103. Each of thecuts 104 extends away from the corner and outwardly away from the end of the opening to which it is connected. Thecuts 104 are located in theside wall 40 of the lower sleeve and extend downwardly and outwardly in said wall' away from the ends of theopening 103. Thus, the over all width of the cooperatingslot 48 is defined by the distance between the outermost ends of thecuts 104 and therefore is substantially greater than the widthof theopening 103.

The first fold-outtab 42 comprises adetent portion 105 and anarrower neck portion 106. Theneck portion 106 connects the detent portion to the first corner 101 of the Thedetent portion 105. is wider than the 1opening 103 but narrower than the over all width of the cooperatingslot 48 measured across the lower ends of the top sleeve.

cuts 104. Thedetent portion 105 presents a pair of shoulders107 adjacent to theneck portion 106. The maximum Widthof the detent portion is measured across the tips of theshoulders 107. The side edges 108 of thedetent portion 105 above theshoulders 107 are inclined inwardly toward theneck portion 106 of the tab. More specifically, the side edges of the tab above theshoulders 107 are curved inwardly and upwardly toward the first corner 101 to provide the said inclination of the edges of the tab and define theneck portion 106 thereof.

In assembling the sleeves, the lower curved end of thetab 42 is inserted in theopening 103 .of the cooperatingslot 48 and, since thedetent portion 105 of the tab is Wider than the opening .103, continued pressure downwardly upon the tab causes the side wall 40' directly below the opening to flex outwardly slightly about an 7 approximateline YY connecting the lower ends of theinclined cuts 104 to allow the detent portion of the tab to enter the slotf48. The shoulders 167 of the tab are so located with respect to the first corner 101 of the top sleeve that when thetop sl eve is in position on the bottom sleeve, the shoulders are below the lower ends of the slot' 104. Thus, after thedetent portion 105 of the tab 42 (including the shoulders 107) passes the lower ends of thecuts 104, the tab snaps into the slot and the a the inclined cuts .104 at the ends of the slot' 48 and thereby block further movement of the tab in this direction. The only way in which the tab can be removed from the slot Without breaking or tearing any part of the sleeve is by, somehow, first pressing the tab outwardlysideways against theside wall 40 of the bottom sleeve in such a way as to again fiex the wall outwardly about the line YY to allow theshoulders 107 to passthr-ough the ends of theslot 48. However, this cannot be done merely by pulling one sleeve away from the other and is almost impossible to do accidentally.

Although the package and cabinet unit of this invention has been shown and described in detail in connection with its use for containing sutures, it may also be used for packaging and dispensing from a cabinet -a variety of other items; such as other surgical products, nuts, bolts,

screws and related hardware items; dried food packaged in envelopes; and any other product which it might be desirable to store or dispense in a number of types or sizes in or from a cabinet formed from the original packages in which the products were shipped without the need for first-removing the products from the packages.
