Abstract
A package assembly includes a number of containers, a heat-shrink wrapping disposed around the containers and tear strip; the tear strip aids in opening the heat-shrink wrapping. The tear strip can be defined by perforations disposed through the heat-shrink wrapping and arranged in pathways. The perforations are cut in the heat-shrink wrapping with a packaging apparatus having a cutting member. The cutting member is used in combination with a die to leave a chad attached to heat-shrink wrapping. Thereafter, the heat-shrink wrapping is shrunk with a heating source in order to bundle containers together within the package assembly.
Description
- This Application claims the benefit of and priority to U.S. Provisional Application No. 61/765,232, filed Feb. 15, 2013.
- Not Applicable.
- In order to bundle containers together for shipment and storage, the containers are oftentimes bundled together in various ways. One way in which containers are bundled together is via the use of a heat-shrink wrapping, which is subsequently heated. In this way, the containers are containers are held in a stable configuration.
- The heat-shrink wrapping has certain disadvantages, however. One such disadvantage is that the heat-shrink wrapping can be difficult to remove once transit of the containers is complete. Removal of the heat-shrink wrapping can require tugging and tearing of the heat-shrink wrapping, or cutting it with a knife, scissors, or other sharp utensil. For the end-user of the product, this can be an onerous task. Further, with the rise of safety concerns, some outlet stores have adopted “no-knife” policies. In these stores, the clerks, stockroom workers, and floor employees are not allowed to carry cutting devices, making removal of the heat-shrink wrapping even more cumbersome.
- An additional drawback of heat-shrink wrapping is that it has a tendency to prevent cooling of the contents within the heat-shrink wrapping. In particular, heat from the packaging assembly can become trapped within the heat-shrink wrapping which, in some cases, can negatively impact the contents within the containers.
- In light of the drawbacks associated with traditional heat-shrink wrapping and packaging methods and apparatuses, there is a need for a package assembly, method, and apparatus that reduces or eliminates the need for usage of specialty tools (e.g., knives, scissors, box cutters), facilitates cooling of the contents within the heat-shrink wrapping, and increases the rate of packaging.

Each is described, in turn, in the following description.
- With regard to
FIG. 1 , apackage assembly 10 is shown. The package assembly includes a plurality ofcontainers 12 and a film or heat-shrink wrapping 14. Thecontainers 12 can be of any desirable shape or configuration, for example cylindrical, conical, frusto-conical, spherical, cuboid, pyramidal, and combinations thereof. Additional examples of suitable packaging configurations can be found in U.S. Pat. Nos. 7,604,114 to Gessler, 7,392,905 to Andersen, 7,370,761 to Andersen, 6,588,594 to Andersen, 5,887,717 to Anderson, and 7,467,504 to Mate, the contents of each of which are herein incorporated by reference in their entirety. - In addition to the foregoing, the heat-shrink wrapping 14 has therethrough a plurality of
perforations 16. In some embodiments, the perforations are arranged in one ormore pathways 18. As shown inFIG. 1 , for example, thepathways 18 include afirst pathway 18 a and asecond pathway 18 b. Between the first andsecond pathways tear strip 20. Thetear strip 20 facilitates easy opening and removal of the heat-shrink wrapping 14. Further, in some embodiments, thepackage assembly 10 includes abase pad 22, on which thecontainers 12 reside. Thebase pad 22 provides additional support for thecontainers 12 during the packaging assembly and transport. - Turning to
FIG. 2 , thepackage assembly 10 shows thetear strip 20 as it is initially pulled away from the remaining heat-shrink wrapping 14. In some embodiments, thetear strip 20 will originate at a hole 24 (also referred to as a “bulls-eye”, which is a byproduct of known packaging techniques), for example at an end of the heat-shrink wrapping 14. It will be appreciated that, at least in some embodiments, the size of thehole 24 is much larger than the size of aperforation 16. - In
FIG. 3 , thetear strip 20 is further pulled away from the remaining heat-shrink wrapping 14. As illustrated, thetear strip 20 peels away from the remaining -shrink wrapping 14 along thepathways 18 formed by theperforations 16. - With regard to
FIG. 4 , thetear strip 20 is almost fully removed from the remaining heat-shrink wrapping 14. In some embodiments, thetear strip 20 is entirely removable from thepackage assembly 10, for example via perforations extending fromhole 24 on one end of thepackage assembly 10 to asimilar hole 24 on another end, or side, of thepackage assembly 10. In some embodiments, however, thetear strip 20 is peeled away from the remaining heat-shrink wrapping 14 but it is not entirely removable. In this way, the orientation of theperforations 16 does not permit complete removal of thetear strip 20. - With regard to
FIG. 5 , in some embodiments, theperforations 16 are spaced at least a distance Y away from thehole 24. This minimum spacing ensures that a tear does not unintentionally form betweenhole 24 and the first perforation 16 a. It will be appreciated that the minimum spacing is a function of the material used for the heat-shrink wrapping 14, the heat used to shrink the heat-shrink wrapping 14, orientation ofcontainers 12, and size and shape of thepackage assembly 10. Indeed, the spacing between thehole 24 and the first perforation 16 a may vary, for example, such that the Y <spacing <X, where X is the maximum permissible spacing to facilitate tearing of thetear strip 20. For instances in which the spacing is greater than X, it becomes too difficult to start a tear along thetear strip 20. - With regard to
FIG. 6 , in some embodiments, thepathways 18 are oriented such that thetear strip 20 is wider at its ends than middle. InFIG. 6 , for example, thetear strip 20 has an hour glass configuration. Such a configuration can be desirable, for example, in order to provide easy access to thecontainers 12. - With regard to
FIGS. 7 and 8 , in some embodiments, thepathways 18 are oriented on one or more sides of thepackage assembly 10. InFIG. 7 , for example,pathways 18 are disposed on all sides of thepackage assembly 10. InFIG. 8 , for example,pathways 18 are disposed on only some of the sides of thepackage assembly 10. In the embodiments shown inFIGS. 7 and 8 , thepathways 18 are parallel to one another and parallel to a plane defined by the bottom of thecontainers 12. Other configurations are also permissible. - With regard to
FIG. 9 , thepathways 18 can also be oriented in a transverse direction. In this way,hole 24, which remains after of the shrink process, is located on a side not associated with thetear strip 20. Instead, an opening 26 is used at anend 28 of thetear strip 20 to facilitate removal of thetear strip 20, as desired. - Turning to
FIG. 10 , in some embodiments, atear strip 20 is disposed on both the top 30 and bottom 32 of thepackage assembly 10. The tear strips 20 can be symmetric or asymmetric. Further, the orientation and/or configuration of thepathways 18 along the top 30 can be the same or different than thepathways 18 along the bottom 32. - With regard to
FIG. 11 , in some embodiments, thepathways 18 extend along only a portion of the top 30 (or any other surface) of thepackage assembly 10. In this way, thetear strip 20 may not be entirely removable from thepackage assembly 10. By maintaining the connection between thetear strip 20 andpackage assembly 10, it will be appreciated that the user will not have to discard two or more separate wrapper components. Instead, the wrapper will remain in a single piece, with the contents of thepackage assembly 10 accessible. - With regard to
FIG. 12 , in some embodiments, thepathways 18 are different from one another such that thefirst pathway 18 a is shorter than thesecond pathway 18b. - With regard to
FIG. 14 , in some embodiments, thepackage assembly 10 comprises 12 containers. Although shown with 12 containers, it will be appreciated that any suitable number ofcontainers 12 can be used, for example 4, 6, 8, 9, 10, 12, 20, 25, 100. Further, thecontainers 12 can be stacked in multiple rows. Additionally, thepackage assembly 10 can have any suitable number ofpathways 18 and any suitable number of tear strips 20. - In at least one embodiment, the heat-
shrink wrapping 14 is provided with only asingle pathway 18 ofperforations 16. By applying force along this single pathway 18 (such as with a user's finger, etc.) the heat-shrink wrapping 14 can be split or otherwise opened along thepathway 18. - Turning to
FIG. 15 , an embodiment of thepackaging apparatus 100 is shown therein. In some embodiments, thepackaging apparatus 100 comprises a heat-shrink wrapping dispenser 102. Thepackaging apparatus 100 further comprises a perforatingassembly 106, aheating source 108, afirst conveyor 110 and asecond conveyor 112. - In some embodiments, the heat-
shrink wrapping dispenser 102 comprises at least one roll of heat-shrink wrapping 14 which feeds out of the heat-shrink wrapping dispenser 102. - As shown in greater detail in
FIG. 16 , the perforatingassembly 106 comprises a die member 114 and a cuttingmember 116. The die member 114 works in conjunction with the cuttingmember 116 to make theperforations 16 in the heat-shrink wrapping 14. As will be appreciated, the cutting member(s) 116 move in and out of the die member(s) 114 to perforate the heat-shrink wrapping 14. Further, the die member 114 has asupport 115 which is disposed on a backside of the heat-shrink wrapping 14 to provide support as the perforations are cut 16. - With regard to
FIG. 17 , a cuttingmember 116 or punch is shown in greater detail. In some embodiments, the cuttingmember 116 has a plurality of cuttingteeth 118 along a portion of its die-facingperimeter 113. In some embodiments, the cuttingteeth 118 do not extend around the entirety of the die-facingperimeter 113, however. Instead, the cuttingmember 116 has a cuttingportion 124 and anon-cutting portion 126 to facilitate creation of non-severed or hangingchads 120. In some embodiments, thenon-cutting portion 126 comprises abevel 117 that extends away from the die-facingperimeter 113. In this way, the cuttingmember 116 perforates the heat-shrink wrapping 14 without severing the chad 120 (FIG. 15 ) from the heat-shrink wrapping 14. Thechad 120 thereby remains attached to the heat-shrink wrapping 14. Maintaining attachment of thechad 120 to the heat-shrink wrapping 14 is beneficial, in some embodiments, in order to reduce or eliminate the production of waste material, which can clutter the assembly process. Consequently, there are nochads 120 to pick up or dispose of. This, in turn, reduces cost and machine down-time. - In some embodiments, the cutting
member 116 producesperforations 16 having c-shape or v-shape perimeters, such that the open part of the “c” or “v” remains attached to the heat-shrink wrapping 14. - With further regard to the cutting
member 116, the skilled artisan will appreciate that it can take on any desirable cross-section, for example circular, triangular, square, rectangular, elliptical, rhomboid, or any other suitable shape or polygon. Examples of some suitable cross sections are shown viadie plate 122 inFIG. 13 . Thedie plate 122 can be used in conjunction with the die member 114 such that the shape of theperforations 16 can be changed, as desired. Returning toFIG. 15 , in some embodiments, the perforatingassembly 106 perforates the heat-shrink wrapping 14 while the heat-shrink wrapping 14 is statically positioned. The heat-shrink wrapping 14 is therefore indexed or otherwise stopped to permit the cuttingmember 116 or punch to be actuated, thereby penetrating the heat-shrink wrapping 14. - In some embodiments, the perforating
assembly 106 is adjustable to permit an operator to easily adjust the pitch of theperforations 16 and the depth of cuttingmember 116 travel, for example to regulate the amount of material holding thechad 120 to the heat-shrink wrapping 14. In some embodiments, an actuator is used to relocate one or more groups of cuttingmembers 116 or punches and die members 114 to adjust the pattern of the perforations. Further, it will be appreciated that the actuator(s) and die members 114 can be employed in any configuration or along any axis in order to adjust the pattern and orientation of theperforations 16. And, thepackaging apparatus 100 can be used, for example, in conjunction with the “Packaging System for Split Package Assembly,” disclosed in U.S. Pat. No. 7,467,504, the contents of which are herein incorporated by reference. - As illustrated via
FIG. 18 , a method of making thepackage assembly 200 is described. In some embodiments, the method includes the steps of providing thecontainers 202. In some embodiments, the packaging apparatus 100 (FIG. 15 ) can be added to an existing assembly line, for example, where the containers were previously assembled onto abase pad 22 or the like. The method of making thepackage assembly 200 further comprises the steps of providing a heat-shrink wrapping 204 and perforating the heat-shrink wrapping 206. After the heat-shrink wrapping 14 has been perforated, it is applied to the containers viastep 208. Thereafter, heat is applied to the heat-shrink wrapping 14 atstep 210 to shrink the heat-shrink wrapping 14. - As will be appreciated, upon application of heat to the heat-
shrink wrapping 14, the size of theperforations 16 is reduced. Further, the chads 120 (FIG. 15 ) shrink in size and do not appear unsightly, upon completion of the package assembly, or interfere with any additional packaging processes. - In order to facilitate homogeneity, reduce viscosity, or to destroy pathogens, mixing machines commonly heat packaged product to temperatures ranging from fifty to ninety degrees Celsius. In the production of perishable goods, and more specifically, perishable goods which can be spoiled by transient periods at moderate temperatures, rapid cooling of the final package becomes of critical importance. Moreover, minimizing package cooling time allows the producer to cycle through product more quickly, reducing work-in-process and space requirements, thus increasing profitability.
- It has been determined that strategically located apertures, when used in conjunction with adequate airflow, can reduce cooling cycles by more than twenty-five percent. Cooling speed, or time rate of thermal dissipation, is increased because the apertures simultaneously increase the exposed heat-dissipating surface area, and reduce the air temperature in the vicinity of the heat-dissipating surfaces. Moreover, by locating the apertures where tension is low in the wrapping, package integrity can be preserved.
- Consequently, the embodiments disclosed in the immediate disclosure have advantages over previously known package assemblies, methods, and packaging apparatus.
- Additionally, it will be appreciated that embodiments having perforations on opposite sides of the packaging apparatus 10 (e.g.,
FIGS. 7 and 10 ), more than one perforatingassembly 106 can be used. - The above disclosure is intended to be illustrative and not exhaustive. This description will suggest many variations and alternatives to one of ordinary skill in this field of art. All these alternatives and variations are intended to be included within the scope of the claims where the term “comprising” means “including, but not limited to.”Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims.
- Further, the particular features presented in the dependent claims can be combined with each other in other manners within the scope of the invention such that the invention should be recognized as also specifically directed to other embodiments having any other possible combination of the features of the dependent claims. For instance, for purposes of claim publication, any dependent claim which follows should be taken as alternatively written in a multiple dependent form from all prior claims which possess all antecedents referenced in such dependent claim if such multiple dependent format is an accepted format within the jurisdiction (e.g. each claim depending directly from claim 1 should be alternatively taken as depending from all previous claims). In jurisdictions where multiple dependent claim formats are restricted, the following dependent claims should each be also taken as alternatively written in each singly dependent claim format which creates a dependency from a prior antecedent-possessing claim other than the specific claim listed in such dependent claim below.
- This completes the description of the preferred and alternate embodiments of the invention. Those skilled in the art may recognize other equivalents to the specific embodiment described herein which equivalents are intended to be encompassed by the claims attached hereto.
