Abstract

An improved sleeve style beverage carton can be processed at or near peak production rates for carton blanks and without the need for manual removal of scrap from apertures in the carton blank. The increase in production rates and efficiency is principally obtained because the stripper pins on the stripper drum used in producing the carton blank consistently and reliably puncture and remove the scrap from apertures in the die cut carton blank thereby alleviating the need to slow or stop the machine for manual removal of the scrap. Advantageously, gusset holes which are die cut in the carton blank are preferably generally trapezoidal-shaped to provide for increased surface area of the gusset hole relative to prior art configurations. The trapezoidal-shaped larger gusset holes provide for a more consistent and reliable removal of the carton material scrap from the gusset hole during production of the blank.

Description

FIELD OF THE INVENTION

This invention relates to cartons. More specifically, this invention relates to an improved beverage carton and associated blank and carton sleeve that improves production rates and efficiencies.[0001]

BACKGROUND OF THE INVENTION

In the marketing of soft drinks, beer and other beverages, such retail consumer products are commonly sold in cans which are grouped together in six or 12 packs. Particularly in the case of 12 can packs, the cans are commonly packaged in cartons to make it easier to handle the product for the wholesaler and the retailer as well as for the retail consumer.[0002]

There are any number of different types of can cartons. One particular type of carton that has found significant commercial success over the years is referred to as a “wrap around” carton. In a wrap around carton, a number of cans, typically 12, are wrapped in a paperboard box or carton that includes top and bottom wall panels, sidewall panels and end flaps on each end. The end flaps at each end of the carton are sealed one to the other, thereby providing a closed or sealed package or carton for the cans.[0003]

A common carton production method involves converting paperboard into carton blanks and then into folded cartons which are eventually erected and filled with the beverage cans. The fabrication of beverage cartons typically begins with paperboard being drawn in a web from a roll of paperboard. Commonly, one surface of the paperboard is printed with a desired graphic design. The paperboard web is then die cut into multiple individual carton blanks. The printed carton blanks are then transferred typically within the same carton manufacturing facility, to a folder/gluer machine where each carton blank is folded and glued into a flattened sleeve or fill-ready carton configuration. The flattened cartons or sleeves are packed and then palletized for shipment to a customer such as a soft drink canner or the like.[0004]

During the conversion of the paperboard into a carton sleeve, the web of paperboard commonly passes between various counter rotating rollers including an impression roller and a stripper drum. Typically, a carton blank includes certain holes or apertures and after each hole is die cut in the paperboard, the paperboard material must be removed from the hole portions of the web as scrap. Such scrap pieces of paperboard are removed by a series of pins arranged on the stripper drum and appropriately configured for the particular carton blank in production. Optimally, the pins puncture the scrap portions of the paperboard and continued movement of the paperboard web and rotation of the stripper drum pulls or strips the scraps from the web.[0005]

However, one inherent requirement in the stripping process is that the pins on the stripper drum be appropriately aligned with the scrap portions of the paperboard web for removal. If the pins do not puncture the scrap portion of the web, the scrap is not removed by the stripper drum and an operator must manually remove the scrap downstream from the stripper drum, for example, by punching the scrap with a screw driver or other tool. Because of the size and processing speed of the converting equipment, it is often difficult to accurately and precisely align the stripper drum with the web for consistent removal of the scrap by the stripper drum. The manual removal of the scrap results in a very inefficient beverage carton sleeve production process. The die cutting machines cannot operate at peek production speeds because of the consistent need to manually remove the scrap from the die cut carton blanks.[0006]

For example, one known type of carton blank is disclosed in U.S. Pat. No. 5,292,059, which is incorporated herein by reference in its entirety. The carton blank shown in the '059 patent includes a number of generally triangular-shaped apertures identified by[0007]

reference numeral

86 in that patent. Such a carton blank is generally shown in FIG.1 herein. The triangular-shaped apertures according to the '059 patent assist in providing a carton having end walls of increased flatness so that it can be utilized as a billboard, display or advertising space while still maintaining adequate structural integrity for the carton.

However, one shortcoming of the carton blank shown in the '059 patent and FIG. 1 herein is that the triangular apertures are sized and configured so that the scrap is not consistently, reliably and efficiently removed from the carton blank during production. Therefore, production of carton blanks of this type are significantly more slower because the machines on which the paperboard is converted to produce such carton blanks cannot run at peak speeds due to the fact that the scrap from the triangular apertures often must be manually removed.[0008]

SUMMARY OF THE INVENTION

As such, there is a need for an improved carton blank and sleeve style carton design which enables the carton manufacturing process to be more efficient and deliver higher production rates.[0009]

Moreover, there is a need for such a carton blank and carton design which provides certain advantages and benefits of known carton designs without the need for repeated manual removal of scrap from apertures in the carton blank during the production process.[0010]

These and other objectives of this invention have been attained by an improved carton and blank design in which the paperboard web can be processed at or near peak production rates into carton blanks and without the need for manual removal of scrap from apertures in the carton blank. Specifically, the carton blank according to this invention can be processed at or near peak production rates of about 625 feet per minute which is a 30 percent or more increase in production rates achieved for similar carton blanks, such as those shown in U.S. Pat. No. 5,292,059 and the like. The increase in production rates is principally obtained because the stripping pins on the stripper drum consistently and reliably puncture and remove the scrap from apertures in the die cut carton blank thereby alleviating the need to slow or stop the machine for manual removal of the scrap.[0011]

In one presently preferred embodiment of this invention, a tubular carton sleeve is adapted to be formed into a carton for holding beverage containers. The carton sleeve is erected and formed from a carton blank that includes a top wall and a pair of sidewalls that are each foldably joined to the top wall. A pair of bottom lap panels are each foldably joined to one of the sidewalls and are adapted for folding relative to the respective sidewalls and joined to each other in overlapping relation to form a bottom wall of the resulting carton. Major end flaps are foldably joined to an end of each of the sidewalls and minor end flaps are likewise foldably coupled to an end of the top wall or bottom wall panels. When the carton is erected, the major and minor end flaps are folded relative to the respective side, top and bottom walls to form end walls of the carton. A plurality of gussets are each foldably joined to one of the major end flaps and an adjacent one of the minor end flaps. The gussets foldably interconnect the major and minor end flaps and are tucked in between those end flaps when the carton is formed. A preferably rectangular bevel panel is formed between the minor end flaps and the associated top and bottom wall adjacent to the gussets. The bevel panel is supported by the adjacent beverage cans when the carton is filled and therefor contributes to the tightness of the carton and the prevention of undesirable crushing of the corners of the carton.[0012]

Advantageously, gusset holes which are formed at a juncture of the top or bottom walls and the adjacent sidewalls in part define the gussets. The gusset holes are preferably generally trapezoidal-shaped to provide for increased surface area of the gusset hole relative to prior art configurations. The trapezoidal-shaped larger gusset holes provide for a more consistent and reliable removal of the carton material scrap from the gusset hole during production of the blank. The trapezoidal-shaped gusset holes are on the average 27 percent larger than triangular-shaped apertures in prior art carton blanks thereby providing for an increased area for the stripper pins on the stripper drums to puncture the scrap material in the gusset hole for removal. As such, even if the paperboard web is not precisely aligned with the location of the stripper pins on the stripper drum, the web can be processed at or near maximum speeds in the production facility because the stripper pin reliably and consistently removes the scrap from the gusset holes, unlike prior art carton blank designs.[0013]

Therefore, the advantages and benefits of certain known wrap around or sleeve style tubular cartons can be achieved with the carton blank, tubular carton sleeve and associated beverage carton of this invention while still allowing for maximum production efficiencies and process rates by avoiding the need for manual removal of the scrap from apertures, gusset holes or the like in the carton blank.[0014]

DETAILED DESCRIPTION OF THE INVENTION

A presently preferred embodiment of a carton blank[0024]10 according to the present invention is shown in FIG. 2 and includes atop wall12.

Sidewalls

14,14 are foldably joined to the side edges of thetop wall12 along

fold lines

16,16.

Bottom lap panels

18,18 are foldably joined respectively to the

sidewalls

14,14 along

fold lines

20,20. A carryinghandle22 is provided for the carton and includes a pair of

flaps

24,24. The details of such a carryinghandle22 are disclosed for example in U.S. Pat. No. 5,106,014 issued Apr. 21, 1992, which is hereby incorporated by reference.

Major end flaps[0025]26,28 are foldably joined to the end edges of

sidewalls

14,14 along

fold lines

30,32, respectively. Minor end flaps34,34 are foldably coupled respectively to bevel

panels

36,36 at the end edges of thetop wall12 along

fold lines

38,38 and40,40. Likewise, partial minor end flaps42,42,42,42 are foldably joined respectively to

partial bevel panels

44,44,44,44 at the end edges of the

bottom lap panels

18,18 along

fold lines

46,46,46,46, and48,48,48,48.

[0026]

Gussets

50 interconnect the adjacent end flaps26 and34;28 and34;26 and42 as well as28 and42. Since all of thegussets50 are virtually identical, only the specific features of thegusset50 will be described here in detail. With particular reference to FIGS. 2 and 5, thegusset50 is foldably joined to the minor end flaps42,34 along afold line52. The opposite end of thegusset50 is foldably joined to the major end flaps26,28 along afold line54.

A[0027]

rectangular bevel panel

36,44 is defined between the fold lines46,48, and38,40 respectively.Bevel panel36 is foldably joined to thetop wall12 and to theminor end flap34. Likewise,bevel panel44 is foldably joined to thebottom lap panels18 and to the partial minor end flaps42.

Specifically, in one presently preferred embodiment the carton blank[0028]10 includes gusset holes74 that are trapezoidal in shape and likewise provide an increased surface area relative to the prior art blank11 having triangular apertures13 (FIG. 1) for more reliable removal of scrap72 (FIGS. 4A and 4B) from thegusset hole74 during production of the carton blank10. In one presently preferred embodiment, thegusset hole74 is trapezoidal-shaped and the gusset holes74ain the carton blank10 proximate thetop wall12 include first and

second edges

76,78 that are each generally parallel to one another and third and

fourth edges

80,82 that are obliquely oriented relative to each other and relative to the first and

second edges

76,78. These gusset holes74ain one presently preferred embodiment have a surface area of about 0.4554 square inches. Additionally, in another presently preferred embodiment the gusset holes74bproximate thebottom lap panels18 of the carton blank10 have first andsecond edges84,86 that are generally parallel to one another and athird edge88 is generally perpendicular to the first andsecond edges84,86 and afourth edge90 is obliquely oriented relative to the first, second and

third edges

84,86,88. The gusset holes74bproximate thebottom lap panels18 have a surface area of approximately 0.4293 square inches. The trapezoidal-shaped gusset holes74a,74baccording to this invention are advantageously larger than the triangular-shapedapertures13 in the prior art carton blank11 of FIG. 1. More specifically, the triangular-shapedprior art aperture13 of FIG. 8 has a surface area of approximately 0.3487 square inches. As such, thegusset hole74bof FIG. 7A is approximately 23 percent greater than that of the prior art triangular-shapedapertures13 of FIG. 8; whereas, the trapezoidal-shapedgusset hole74aof FIG. 7B is 31 percent larger than the triangular-shapedaperture13 of the prior art in FIG. 8. On the average, the gusset holes74a,74bof FIGS. 7A and 7B of this invention are 27 percent larger than theprior art aperture13 of FIG. 8. While the gusset holes74a,74bare shown as being different trapezoidal shapes and sizes, the gusset holes74 may be the same configuration and size and preferably trapezoidal and as large as practically possible to increase the likelihood of removing the scrap. The advantageous size and configuration of the gusset holes74a,74bresult in an increase in production because theweb10amoves at a rate of approximately 625 feet per minute which is a 30 percent or greater increase relative to production rates for the prior art carton blank11 of FIG. 1. As such, the carton blank10 configuration according to this invention and shown in FIG. 2 provides a significant increase in production rate and advantage over known prior art designs due in large part to the configuration of the gusset holes74a,74b.

To complete the basic elements of the carton, one or[0029]

more outlet ports

56 are each defined byseverance lines58 as shown in FIG. 2. The severance lines58 are formed in at least one of thesidewalls14. The outlet port(s)56 provide(s) a dispensing means for dispensing the beverage cans from the carton. A preferred embodiment in theoutlet port56 is disclosed U.S. Pat. No. 5,249,681, issued Oct. 5, 1993 and hereby incorporated by reference.

To form a[0030]

tubular carton sleeve

60 from the carton blank10, the

bottom lap panels

18,18 are partially overlapped onto one another and glued together, typically on a folder-gluer machine as is well known in the art. Thesleeve60 can then be collapsed about

fold lines

16 and20 for storage and/or shipping.

To form the carton from the[0031]

sleeve

60, the minor end flaps34,42, as viewed in FIGS. 5 and 6, are pivoted and folded into the positions shown in FIG. 6. This action causes the

bevel panels

36,44 to swing inwardly together with eachgusset50 into the respective positions as shown in FIGS. 5 and 6. Following this, themajor end flap26 is folded inwardly along thefold line30 andmajor end flap28 is then folded inwardly alongfold line32 until the major end flaps26,28 overlap and are glued together to form end walls. Once this is completed on both ends of thesleeve60, the carton is formed. The articles are loaded into the carton through the open end or ends of the carton.

It should be recognized that as used herein, the terms “top”, “bottom” and “side” with respect to the various carton walls or components are relative terms, and that the carton and/or its contents may be re-oriented as necessary or as desired. Further, rather than the bottom wall being formed from[0032]

separate lap panels

18,18, it will be recognized that the carton blank10 may be rearranged whereby some other panel is formed as a composite from lap panels.

One advantage of this invention is that the end walls of the completed carton have large flat surfaces and that the carton still maintains adequate integrity due to the[0033]

bevel panels

36,44 at the ends of thetop wall12 and bottom wall. The endwall enlarged flat surfaces are useful as space for carrying printing such as an advertisement, trademark, and other information.

A principal advantage of this invention is demonstrated in FIGS. 3, 4A,[0034]4B,7A,7B and8. Once a web ofpaperboard10ais die cut, it commonly passes between various counter rotating rollers and drums. One such drum is astripper drum62 having a number ofstripper pin assemblies64 withpins66 projecting from the outer circumference of thedrum62. Each stripper pin is mounted to thedrum62 on abase68 and amovable sleeve70 surrounds thepin66.

Referring to FIGS. 3, 4A and[0035]4B, as the die cutpaperboard web10apasses in the direction of arrow A past thestripper drum62 rotating in the direction of arrow B, the stripper pins66 are spaced and configured on thestripper drum62 so that one of thepins66 puncture thescrap portion72 of thepaperboard10aformed in thegusset hole74. Once thestripper pin66 punctures thescrap72 as shown in FIG. 4A, continued movement of thepaperboard web10aand thestripper drum62 separates thescrap72 and pin66 from thepaperboard web10athereby exposing thegusset hole74 as shown in FIG. 4B. Due to the centrifugal forces of therotating stripper drum62, themovable sleeve70 slides along thestripper pin66 to project in the direction of arrow C and thereby dislodge thescrap72 from thepin66 for disposal. As such, upon subsequent rotation of thestripper drum62, thestripper pin66 is free to puncturescrap72 in a subsequent die cut portion of thepaperboard web10a.

The above-described removal process for[0036]

scrap

72 from die cut holes or apertures in the carton blank10 is generally the desired objective of many carton blank production facilities and paperboard converters. However, because of the design of prior art carton blanks11 such as those shown in FIG. 1, frequently the stripper pin does not puncture the scrap portions of the die cut blank and, consequently, does not remove the scrap from die cut holes or apertures in the paperboard web. As a result, the process must be halted or interrupted so that an operator manually punctures the scrap from the die cut holes with a screw driver or the like. The misalignment of thestripper pin66 relative to the scrap may be the result of a number of factors including misalignment of the web relative to thestripper drum62, inaccurate placement of thestripper pin assemblies64 on thestripper drum62 for a given die cut configuration or the like. Additionally, wobble or loosely mounted stripper pins66 are commonly utilized so that dust or other foreign matter can be easily and/or automatically ejected from thestripper pin assembly64 to prevent clogging, jamming or the like. Such inherent movement in thestripper pin66 may also create inaccuracies in the puncturing of the paperboard web.

Nevertheless, the carton blank[0037]10 according to one embodiment of this invention overcomes these problems and allows for maximum or near peak production rates becausescrap72 in particular apertures in thegusset hole74 is consistently and reliably punctured by the stripper pins66 for removal thereby alleviating the requirement for interruption of the process or manual removal of the scrap.

From the above disclosure of the general principles of the present invention and the preceding detailed description of at least one preferred embodiment, those skilled in the art will readily comprehend the various modifications to which this invention is susceptible.
