Description

  The present invention relates to a multi-packaging device in which adjacent strip members in a plastic sheet have different physical characteristics and carry a plurality of containers together.

  As with the device according to the present invention, a multi-packaging device is generally used to integrate a plurality of containers. Typically, containers include bottles, cans and other containers having side walls and edges (raised ribs) around the top of the container. Most of the prior art in this technical field, especially multi-packaging devices composed of elastic polymeric materials, include multi-packaging devices that engage edges (ribs) around the top of the container. Another type of multi-packaging device is a side wall carrier whereby the multi-packaging device engages the side wall of the container.

  Regardless of the type of multi-packaging device, there is an attempt in the art to provide a multi-packaging device that can be used for a certain range of error container dimensions, particularly a certain range of error container diameter. In general, since the container engaging portion of a multi-packaging device has an elasticity specified by the modulus of elasticity of the multi-packaging device, that is, “modulus”, the performance of the multi-packaging device is determined by the stretched container engaging portion. Depending on the engagement between the container and the side wall or edge of the container. Container diameters that do not fall within the narrow diameter error range will either cause the container engaging portion to stretch too much, causing a permanent loss of elasticity called “neck down”, or will not stretch the container engaging portion at all. In this case, packaging fails.

  Prior art multi-packaging devices typically require several different types or shapes to accommodate different diameters. Typically, a simple construction multi-packaging apparatus can accommodate a container diameter with an error range of 5.08 millimeters (0.200 inches). Accordingly, there is a need to provide a multi-packaging device that can accommodate container diameters with a wide error range.

  Furthermore, prior art multi-packaging devices cannot be used in a wide range of applications because the components of the multi-packaging device cannot be adapted to have various physical properties.

  One of the objects of the present invention is to provide a multi-packaging apparatus that can be used in a wide range of applications, with the flexibility of its constituents having various physical properties.

  Another object of the present invention is to provide a multi-packaging device that integrates multiple containers so that the containers do not move relative to each other.

  Another object of the present invention is to provide a multi-packaging apparatus capable of integrating containers having a plurality of first diameters and integrating containers having a plurality of second diameters.

  It is a further object of the present invention to provide a multi-packaging device that can be used in a wide range of applications and thus eliminates the need to make many different devices having different sizes and shapes.

  It is a further object of the present invention to provide a multi-packaging device that is placed around a container sidewall when the sidewall diameter is within a diameter range of about 25.4 millimeters (1 inch).

  Multi-packaging devices that can accommodate a range of container diameters are preferably made from thermoplastic materials such as plastic sheets. The elastic polymer having a lower modulus than the plastic sheet is preferably integrated with the plastic sheet. The elastic polymer preferably forms individual segments within the plastic sheet so that the multi-packaging device has a thickness that is generally linear.

  According to another preferred embodiment of the present invention, the multi-packaging device is a plastic having a generally uniform thickness and individual strips interleaved with different materials so as to extend parallel to the array of holes. Each of the interleaved individual strips comprising a sheet and having a plastic sheet has at least one physical property different from each of the adjacent strips. Preferably, the plastic sheet has individual strips interleaved with different materials that are coextruded to form a generally uniform thickness and aligned and aligned with each other. Different physical properties in adjacent strips of different materials can have one or more of two different moduli, two different coefficients of friction, two different colors, or two different recycled material contents.

  The plastic sheet with the integral elastic polymer is then die cut to form a plurality of holes, each hole preferably receiving a container. The holes are preferably arranged in an array having rows and columns. The holes should also be formed such that the elastic polymer can be reached in one of several preferred arrangements adjacent to the plastic sheet and / or the adjacent strip material is formed in the required location. Is preferred. In certain preferred embodiments of the present invention, the elastic polymer is placed in individual segments within the plastic sheet between the rows of holes. In another preferred embodiment of the invention, individual strips or elastic polymers of different materials are disposed adjacent to the plastic sheet along the outer band of the row of holes, and adjacent strips within the plastic sheet. The material is contained in a band inside the row of holes. In a further preferred embodiment of the invention, individual strips or elastic polymers of different materials are arranged in the plastic sheet between the rows of holes and adjacent at least a part of the perforation.

  The container is then inserted into each hole to form the assembly of the multi-packaging device, and at least one of the plastic sheet and the elastic polymer is appropriately stretched depending on the container diameter. Optionally or additionally, a part of the plastic sheet grips according to the respective coefficient of friction. Furthermore, a portion of the plastic sheet can have a different recycled material content or a different color than a portion of an adjacent strip of different material within the plastic sheet.

  FIG. 1 shows a typical multi-packaging apparatus according to the prior art. As noted above, prior art multi-packaging devices can accommodate container diameters within an error range of about 5.08 millimeters (0.200 inches). Thus, in order to accommodate container diameters that exceed an error range of 5.08 millimeters (0.200 inches), a number of embodiments for both multi-packaging devices and packages applying multi-packaging devices and the like Variations are required. Prior art multi-packaging devices typically consist of a plastic sheet 20 having a modulus and a plurality of hole groups 25. The multi-packaging apparatus shown in FIG. 1 is an illustration of the prior art and represents an apparatus composed of a single plastic sheet 20 that uses no additional material. The physical form of the multi-packaging device shown in FIG. 1 can be used with the invention described later.

  2, 5, 8 and 11 show a multi-packaging apparatus 10 for carrying an arrayed container according to four preferred embodiments of the present invention. The physical shape of the multi-packaging device 10 shown in FIGS. 2, 5, 8 and 11 is merely exemplary and can be changed without departing from the principles of the present invention.

  Somewhat similar to the type of multi-package carrier described above, the multi-packaging apparatus 10 according to one of the preferred embodiments of the present invention is preferably a thermoplastic, such as a low to medium density polyethylene sheet material or plastic sheet 20. Formed from material. As is common in the field of resin extrusion, the plastic sheet 20 has the longitudinal direction of the plastic sheet 20 coincident with the longitudinal direction specified by the extrusion direction perpendicular to the end face of the extrusion die, and the plastic sheet 20 Are extruded so that their transverse dimensions coincide with the direction of the transverse axis parallel to the extrusion die.

  In three preferred embodiments of the present invention, shown separately in FIGS. 2-4, 5-7 and 11-13, the elastic polymer 40 is formed on the multi-packaging device 10 along one plane. Integrated into the plastic sheet 20 to form a plurality of individual segments of the elastic polymer 40 that are essential to the plastic sheet 20. The elastic polymer 40 is attached to the plastic sheet 20 by coextrusion, welding or other methods to form a linear, single thickness multi-packaging device 10. The welding described in the specification and claims may be a hot weld, a cold weld, a lamination or two materials as known to those having ordinary skill in the art. Can be identified by other methods of bonding.

  Depending on the method employed to integrate the elastic polymer 40 to the plastic sheet 20, the elastic polymer 40 and the plastic sheet 20 have a thickness that slightly overlaps or varies slightly with respect to each other. However, one of the objects of the present invention is to produce a plastic sheet 20 having a uniform thickness that is almost uniform and almost unchanged. 4, 7 and 13 are cross-sectional views of a multi-packaging device 10 according to three preferred embodiments of the present invention, where the elastic polymer 40 and the plastic sheet 20 comprise two separate materials and A multi-packaging device having one thickness is formed. It is desirable to use an elastic polymer 40 that is compatible with the plastic sheet 20 for reprocessing and recycling.

  The elastic polymer 40 preferably has a lower modulus than that of the plastic sheet 20, and is therefore preferably more elastic than the plastic sheet 20. Therefore, the elastic polymer 40 preferably stretches more than the plastic sheet 20 when subjected to the same stress as the plastic sheet 20. As described throughout the specification and claims, a low modulus material has a higher elasticity than a high modulus material. The carrier 10 can be made exclusively from a low modulus material such as the elastic polymer 40, but the cost of such a carrier 10 is very high for large scale commercial applications.

  In one preferred embodiment of the present invention, as shown in FIGS. 8-10, a plurality of longitudinally arranged weakening lines (preferably perforations 30) are pre- It arrange | positions along the plastic sheet 20 by the defined space | interval. The perforation 30 can be applied by a perforated wheel, or some other method known to those having appropriate skill in the art, such as perforating the plastic sheet 20. . In other preferred embodiments of the present invention, the perforation 30 may be used to reduce the strength of the plastic sheet 20 such as reducing the thickness of the plastic sheet 20 along a line similar to the longitudinal direction. May be replaced.

  In a preferred embodiment of the present invention as shown in FIGS. 8-10, the elastic polymer 40 is disposed on the plastic sheet 20 so as to be adjacent to at least a portion of the perforation 30. In one of the preferred embodiments of the present invention, the elastic polymer 40 is arranged to completely cover the line of the perforation 30 of the plastic sheet 20, as shown in FIG. The The elastic polymer 40 may be laminated or extrusion coated on the plastic sheet 20 or may be coextruded with the plastic sheet 20. Alternatively, the processing method of the elastic polymer 40 may be a method applied to the plastic sheet 20 using spraying, tape, roller coating or processing techniques known to those skilled in the art. In this preferred embodiment of the present invention, the elastic polymer 40 and the plastic sheet 20 form a greater thickness than the plastic sheet 20 alone, as shown in FIG. 10, which is a 10-10 cross section of FIG. The elastic polymer 40 is preferably attached to the plastic sheet 20 before pressing the individual multi-packaging device 10.

  In the preferred embodiment shown in FIGS. 11-13, the elastic polymer 40 is integrated with the plastic sheet 20 by coextrusion or other methods, and the cross section as shown in FIG. Form. As shown in FIG. 13, the plastic sheet 20 has a reduced thickness and forms a groove with an elastic polymer 40.

  After the elastic polymer 40 is integrated with the plastic sheet 20, ie, attached to the plastic sheet 20, the resulting sheet material is preferably pressed or die cut to form individual multi-packaging devices 10. . As described above, the plastic sheet 20 is die-cut after the plastic sheet 20 and the elastic polymer 40 are integrated, but for the preferred embodiments described above and FIGS. It may be die cut before either or both of the weakening line 30 and the elastic polymer 40 are applied. The plastic sheet 20 is preferably formed using a stamping press to die cut material and thereby obtain the features of the multi-packaging apparatus 10 described above.

  The plastic sheet 20 integrated with the elastic polymer 40 is die-cut to form a plurality of hole groups 25, each of which can receive a container. The hole groups 25 are preferably arranged in an array having rows and columns. As shown in FIGS. 2, 5, 8, and 11, an array of two rows and three columns is preferred to form a multi-packaging device 10 that holds six containers. Therefore, the row of the hole group 25 extends in the length direction of the plastic sheet 20, but is counted in the transverse direction along the width of the plastic sheet 20, and the column of the hole group 25 extends in the width direction of the plastic sheet 20. Are counted in the longitudinal direction along the length of the plastic sheet 20. 2, 5, 8 and 11 show a multi-packaging device 10 holding six containers, the present invention is not so limited, and the multi-packaging device 10 may be implemented in any arrangement that is feasible. It should be noted that hole groups 25 can also be included.

  In one preferred embodiment of the present invention, as shown in FIGS. 2 and 11, the elastic polymer 40 is disposed longitudinally and disposed between the hole groups 25 in the row of hole groups 25. In addition, a hole group 25 is formed. With this shape, the elastic polymer 40 can be stretched in a high stress region between the hole groups 25 and suppresses the neck-down tendency of the plastic sheet 20 in that region.

  It is preferable that the hole group 25 has an elliptical shape so that the long axis of the hole 25 extends in the longitudinal direction. However, the hole group 25 may have any opening and is not essential, but an elongated opening having an opening extending in the longitudinal direction is preferable. As shown in FIGS. 2, 5, 8 and 11, the group of holes 25 is narrower in the transverse direction than the holes in the prior art of FIG. The narrow group of holes 25 makes it possible to produce a multi-packaging device 10 with a greater number of rows using the same amount of sheet material in the transverse direction as the prior art multi-packaging device.

  In another preferred embodiment of the present invention, as shown in FIG. 5, the holes 25 are arranged on the outside of the rows of holes 25 in the multi-packaging apparatus 10 with the elastic polymer 40 disposed longitudinally. Arranged along the band. The outer band of the row of hole groups 25 generally forms part of the multi-packaging apparatus 10 that clearly follows the perimeter of the assembly of the multi-packaging apparatus 10 and the container engaged with the hole group 25. This shape allows the elastic polymer 40 to stretch to accommodate multiple container diameters, but nevertheless the high modulus plastic sheet 20 is more stressed at the central portion of the multi-packaging device 10. Can be absorbed.

  In another preferred embodiment of the present invention, as shown in FIG. 8, a perforated line of weakness 30 (and hence also an elastic polymer 40) is arranged longitudinally and the group of holes in a row of groups 25 of holes. The hole group 25 is formed so as to be disposed between the holes 25. In this preferred embodiment, a linear perforation or other weakening line 30 bisects the minor axis or other transverse dimension of the group of holes 25. The weakening line 30 such as the perforated or reduced thickness plastic sheet 20 is centered on the minor axis of the hole group 25 to obtain the desired performance depending on the physical properties of the plastic sheet 20 and the elastic polymer 40. May be offset from

  In yet another preferred embodiment of the present invention, as shown in FIG. 11, the elastic polymer 40 is disposed longitudinally and disposed between the hole groups 25 in the row of hole groups 25. Hole group 25 is formed. However, the elastic polymer 40 may be coextruded anywhere else in the carrier 10 such that the desired stretch properties are obtained.

  In a special case of this embodiment of the present invention, the multi-packaging apparatus 10 may comprise a group of holes 25 having a pitch 50 of about 76.2 millimeters (3 inches). The pitch 50 is the distance between the centers of the hole groups 25 adjacent in the longitudinal direction. The dimensions of the pitch 50 are important. This is because when the multi-packaging apparatus 10 is used in a normal-use apparatus, the dimensions of the multi-packaging apparatus 10 must be maintained in order to attach the multi-packaging apparatus 10 to a container. Since the pitch 50 in the multi-packaging apparatus 10 is not changed, it is possible to use one type of application apparatus for a plurality of container diameters within a certain range. In the prior art multi-packaging apparatus, in order to maintain the pitch 50 dimension, other dimensions of the multi-packaging apparatus 10 need to be modified to accommodate different container diameters.

  The elastic polymer 40 preferably has a lower modulus than that of the plastic sheet 20, and thus is preferably more elastic than the plastic sheet 20. In one preferred embodiment, the elastic polymer 40 is a metallocene-based or polyolefin-based plastomer. The elastomeric polymer 40 can have any other material known to those having ordinary skill in the art and exhibit properties such as high elongation, low modulus and high transparency.

  In the preferred embodiment of the invention shown in FIGS. 2-7, when a container is inserted into the multi-packaging device 10 to form a multi-packaging device 10 assembly, the small diameter container is The elastic polymer 40 of the device 10 is stretched. When a larger diameter container is inserted into the multi-packaging device 10, the plastic sheet 20 and the elastic polymer 40 stretch until a predetermined stress level is reached, at which the elastic polymer 40 is strain-hardened, Therefore, it stretches at an unbalanced and slower rate than the plastic sheet 20. In this manner, the multi-packaging apparatus 10 can be engaged and integrated with a plurality of container diameters within a certain range without causing an elastic loss or neck-down of the plastic sheet 20 or the elastic polymer 40. .

  A longitudinal weakening line 30 such as the perforation shown in FIGS. 8 to 10, or a weakening line 30 formed by reducing the thickness of the plastic sheet 20 shown in FIGS. In a preferred embodiment, when the container is inserted into the multi-packaging device 10, the weakening line 30 can be broken by transverse stresses that occur to act on the plastic sheet 20. However, since the elastic polymer 40 maintains its elasticity, that is, the elasticity of the entire multi-packaging apparatus 10, the multi-packaging apparatus 10 can maintain an effective state. This is because the physical properties change more rapidly from the modulus of the plastic sheet 20 to the modulus of the elastic polymer 40 as compared with the embodiment in which the plastic sheet 20 and the elastic polymer 40 are linearly integrated in the present invention. Have

  Therefore, the multi-packaging apparatus 10 integrates a group of containers having a plurality of diameters within a certain range. Typical current containers, particularly bottles, have a diameter in the range between about 66.04 millimeters (2.6 inches) and about 73.66 millimeters (2.9 inches). The multi-packaging device 10 according to the present invention can be a single size device that engages a relatively wide range of existing and imaginable containers.

  The multi-packaging apparatus 10 is a plastic sheet 20 that is used for the smallest container diameter in the range of acceptable container diameters, such as 50.8 millimeter (2 inch) diameter in existing low end containers. It is preferable that the dimension is based on the modulus. The stretch properties and relative modulus of the elastic polymer 40 are determined from the largest container diameter in the range of acceptable container diameters, such as 76.2 millimeters (3 inches) diameter in existing high-end containers. The pitch 50 is sized to accommodate the largest container diameter in the range of acceptable container diameters, such as 76.2 millimeters (3 inches). The hole group 25 in the central portion of the multi-packaging device 10 is smaller than the holes in the outer portion of the multi-packaging device 10 to minimize “puckering” of the multi-packaging device 10 assembly. Must be a dimension.

  In one preferred embodiment of the present invention, the multi-packaging apparatus 10 includes a generally uniform thickness and discrete strips of different materials interleaved so as to extend parallel to the array of holes 25. Each of the interleaved individual strips of the plastic sheet 20 has at least one different physical property that is different from each of the adjacent strips. FIG. 14 schematically illustrates an arrangement of the multi-packaging apparatus 10 in which the individual strip materials that are interleaved are formed in the plastic sheet 20. Preferably, the plastic sheet 20 has individual strips interleaved with different materials so as to be coextruded to form a generally uniform thickness and aligned side by side with each other.

  As described in detail herein, at least one different physical property that exists between adjacent strips in interleaved individual strip materials may be a modulus or “modulus”. Thus, each strip material in the plastic sheet 20 can have a different modulus from the adjacent strips.

  Another different physical property that exists between adjacent strips in the plastic sheet 20 is the coefficient of friction. Thus, each strip material in the plastic sheet 20 can have a higher or lower coefficient of friction or “stickiness” than adjacent strips.

  Another different physical property that exists between adjacent strips in the plastic sheet 20 is the recycled material content. Solid materials as used herein include pelletized raw materials and reground from scrap removed from plastic sheet 20 during the manufacturing process. As a result, the term solid material includes all implant materials including re-ground products. The recycle material used in this specification is a recycle material obtained from a secondary source consisting of a material that is not initially used in the manufacture of the multi-packaging apparatus. Thus, each strip material in the plastic sheet 20 can have a greater or lesser density of recycled material than each of the adjacent strips. Optionally, one strip material may exclusively comprise solid material and one or more adjacent strip materials may comprise recycled material.

  Another different physical property present in the adjacent strip material within the plastic sheet 20 is color. Thus, each strip material in the plastic sheet 20 can have a different color from each of the adjacent strips.

  In order to make the multi-packaging device 10 customized according to the required application, the aforementioned physical properties may be given individually in the plastic sheet 20, or mixed and blended in the plastic sheet 20. Also good. Thus, the multi-packaging apparatus 10 according to the present invention can comprise alternating strip materials, eg having different moduli and different coefficients of friction or having different recycled material contents and different colors.

  In accordance with a preferred embodiment of the present invention as shown in FIG. 14, the multi-packaging device 10 uses one of the different materials as disposed along each of the outer bands 85 in the row of holes 25. Thereby forming a total of three interleaved individual strips of different materials. Thereby, as shown, one of the interleaved individual strips is disposed along a longitudinal linear inner portion 95 disposed between the hole groups 25 in the hole array. As a result, when the container is assembled into a complete package, one of the strip materials in the plastic sheet 20 is placed along the inner portion 95 of the package and adjacent strips of the plastic sheet 20 are placed on the outer portion 85 of the package. Be placed.

  According to a preferred special embodiment of the present invention, the multi-packaging apparatus 10 comprises a plastic sheet 20 having a plurality of container receiving hole groups 25 arranged adjacent to the rows and columns. The first portion of the plastic sheet 20 has a first coefficient of friction and a first modulus, and the second portion of the plastic sheet 20 has a second coefficient of friction and a second modulus, where the first coefficient of friction and the first modulus. The two friction coefficients are different, and the first modulus and the second modulus are preferably different. As described above, the first portion of the plastic sheet 20 preferably forms a strip along the length of the multi-packaging device 10.

  When the previous embodiment of the multi-packaging device 10 is assembled into a package, a plurality of interconnected bands formed by the plastic sheet 20 are located about 25.4 millimeters (1 inch) away from the top of the container. Is done. The package in this embodiment has a greater container resistance along a portion of the plastic sheet 20, which container resistance is along the first friction coefficient, particularly the middle portion of the plastic sheet 20 that extends between the holes 25. Includes coefficient of friction. The container resistance used in this special case and claims is the total amount of resistance that the plastic sheet exhibits when a generally smooth container slides on the surface of the plastic sheet. Thus, the first coefficient of friction generates a container resistance that is about two to three times the container resistance obtained from the second coefficient of friction.

  One of the foundations of the above-described embodiment is to optimize the physical properties of the plastic sheet 20 by the placement of the critical stress region 80 and the non-critical stress region 90 of the package. The broken lines in FIG. 14 schematically illustrate the critical stress region 80 and the non-critical stress region 90 for a particular multi-packaging device 10. The critical stress region 80 usually exists in a portion of the plastic sheet 20 that extends around the container and holds the container. For example, as indicated by a broken line in FIG. 14, the critical stress region 80 extends at least partially around the tip 27 of the hole group 25 and is the boundary of the band 85 outside the multi-packaging device 10. It extends along the outer region 29 of the hole group 25.

  The critical stress region 80 preferably has a material that stretches and recovers. In general, solid materials are more likely to have this type of recovery property than recycled materials. The modulus of the material also affects the material's ability to stretch and recover. As another shape of at least one of the hole group 25 and the multi-packaging apparatus 10, the critical stress region 80 may be different from that schematically illustrated by the broken line in FIG.

  The non-critical stress region 90 is typically less stressed than the critical stress region 80 during and after the container is held. In practice, a portion of the plastic sheet having a non-critical stress region 90, such as the inner portion 95, has a lower coefficient of friction or higher recycled material content than the critical stress region 80. According to one preferred embodiment of the present invention, the position of the strips in the interleaved individual strips disposed along the inner portion 95 of the multi-packaging device 10 depends on the relative position of the critical stress region 80. Identified. Accordingly, the strip disposed along the inner portion 95 of the multi-packaging device 10 is formed based on how the multi-packaging device 10 is stressed while the container is held. Optimally, as shown in FIG. 14, the strip disposed along the inner portion 95 of the multi-packaging device 10 coincides with the non-critical stress region 90 of the multi-packaging device 10.

  In the foregoing specification, the invention has been described with reference to several preferred embodiments and a number of detailed examples have been presented for purposes of illustration. However, as will be apparent to those skilled in the art, the apparatus of the present invention may have further embodiments without departing from the basic principles of the present invention and is described herein.
