United States Patent 3,246,746 PACKAGING TRUCTURE Danforth Holley, Grosse Pointe Shores, Mich, assignor to Holley Plastics Company, Warren, Mich, a corporation of Michigan Filed Mar. 9, 1964, Ser. No. 350,155 3 (Ilaims. (Cl. 206-65) This application is a continuation in part of co-pending application Serial Number 16,506, filed March 21, 1960, now Patent Number 3,124,421, dated March 10, 1964.
The invention relates generally to packaging structure and refers more specifically to composite paper board and deformable plastic multi-capsule packaging structure including nesting and locking features and requiring no external packaging.
Multi-capsule plastic packages have been known in the past. Further, it has been known to place multi-capsule plastic packages back to back with the individual capsules thereof nested for economy in storing and shipping.
Such package structure in the past, however, has been deficient in that lateral movement of the separate packages nested together has been possible so that external packaging of the nested packages has been required.
Also, prior multi-capsule packages where they have been connected together along one side in nested relation, have been easily separable on relative angular movement therebetween about the connected side as a pivot. Tab structures have therefore been required to maintain the prior multi-capsule plastic packages secured together in nested relation.
It is therefore one of the objects of the invention to provide an improved multi-capsule packaging structure.
Another object is to provide packaging structure including a pair of elongated multi-capsule packages in which the capsules extend transversely and are spaced apart longitudinally for nesting, which packages are positioned back to back and are connected together at one end thereof to provide locking together of the packages with the capsules in nested relation.
Another object is to provide packaging structure as set forth above wherein the individual capsules are substantially rectangular in cross section longitudinally of the separate multi-capsule packages.
Another object is to provide packaging structure as set forth above wherein each separate package includes a cover sheet and the capsules in each separate package have transversely longitudinally spaced apart sides converging toward the cover sheet.
Another object is to provide packaging structure as set forth above wherein the edge portion of the transversely extending sides of the separate capsules converge outwardly of the cover sheet.
Another object is to provide packaging structure as set forth above wherein each of the individual multi-capsule plastic packages comprises an elongated cover sheet and a base member having a plurality of transversely extending pockets spaced apart longitudinally thereof sealed to the cover sheet around the periphery of the pockets.
Another object is to provide packaging structure as set forth above wherein the cover sheet is folded longitudinally and one side thereof is providing with openings therethrough through which the separate pockets of the base members extend with the base members sandwiched between the folded halves of the cover sheet.
Another object is to provide packaging structure as set forth above wherein the cover sheet is paper board coated with plastic.
Another object is to provide packaging structure as set forth above wherein the cover sheet is paper board uncoated with plastic.
Another object is to provide packaging structure as set forth above wherein both the base member and cover sheet are plastic.
Another object is to provide a simple multi-capsule packaging structure which is economical to manufacture and efficient in use.
Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings illustrating a preferred embodiment of the invention wherein:
FIGURE 1 is a perspective view of a multi-capsule packaging structure constructed in accordance with the invention.
FIGURE 2 is an enlarged cross section view of the packaging structure illustrated in FIGURE 1 taken substantially on line 2-2 in FIGURE 1.
FIGURE 3 is an enlarged longitudinal section view of a modification of the packaging structure illustrated in FIGURE 1 in a closed position.
FIGURE 4 is an enlarged longitudinal view of another modification of the packaging structure illustrated in FIGURE 1 in a closed position.
FIGURE 5 is a perspective view of still another modification of the packaging structure illustrated in FIG- URE 1.
FIGURE 6 is an enlarged section view of the packaging structure illustrated in FIGURE 5 taken substantially on line 66 in FIGURE 5.
FIGURE 7 is a plan View of the cover sheet of the packaging structure illustrated in FIGURE 5 before it is folded and assembled with a pair of base members.
With particular reference to the figures of the drawing, one embodiment of the invention will now be considered in detail.
As illustrated in FIGURE 1, the multi-capsule combination paper board and plastic packaging structure 10 in cludes a pair of base members 12 having a plurality of pockets 14 therein and an elongated cover sheet 16. As illustrated in FIGURE 1, the multi-capsule packaging structure 10 is constructed by securing the base members 12 to the cover sheet 16 about the periphery of the pockets 14 with the base members positioned so that the pockets 14 nest with the packaging structure closed.
More specifically, the base members 12 are elongated sheets of transparent deformable but form sustaining plastic having the property of returning to an original form after slight deformation thereof on removal of a deforming force such as cellulose acetate, cellulose acetate butyrate or vinyl. The pockets 14 formed in the base members 12 are shown, substantially rectangular in cross section longitudinally of base members 12 but in FIGURE 1 are provided with a slight draft angle so that the sides thereof converge slightly toward the bottom of the pockets 14. The pockets 14 are spaced apart longitudinally of the base members 12 a distance to snugly receive the pockets 14 of similar base members 12 positioned in back to back nesting relation.
The cover sheet 16, as previously indicated, is an elon gated paper board member which is folded transversely to provide tabs 18 and 20 and to provide the connecting portion 22 which is substantially the same height as the individual pockets 14 of base members 12. The cover sheet 16 illustrated in FIGURES 1 and 2 is a relatively stiff porous virgin fiber board such as kraft board, bleached sulfate paper or white patent coated news print.
In production the cover sheet 16 is prepared in blank form and is creased to provide fold lines for tabs 18 and 20 and to provide the connecting portion 22. A pair of base members 12 are then positioned on the cover sheet 16 with articles to be packaged within the pockets 14 and with the individual pockets positioned in nesting relation with the packaging structure illustrated in FIGURE 1, closed. A plastic to paper board seal 24 is then produced around the periphery of each of the pockets 14 to provide individual sealed capsules.
Deep seal tear lines 26 may be simultaneously produced between the individual capsules if desired. Also deep seal tear lines 28 permitting ready entry into the individual capsules may be produced at this time. It is contemplated that the sealing of the base sheets to the cover sheets and the producing of the deep seal tear lines will be by heat and pressure and that the plastic base sheets will be thermo plastic. The heat may of course be produced by high frequency electronic heating devices.
The cover sheet is subsequently folded as shown in FIGURE 1 to close the packaging structure with the individual pockets of one base member 12 snugly nested between individual pockets of the other base member. On closing of the packaging structure 10 illustrated in FIGURE 1 the edge portions of the individual capsules will deform to permit the capsules to nest tightly within one another and will assume their substantially rectangular longitudinal cross section shape after the packaging structure is completely closed.
In accordance with the invention, there will thereafter be no tendency for the two halves of the multi-capsule packaging structure 10 to open in the manner of FIG- URE 1 since the individual capsules must again be deformed to permit opening as shown in FIGURE 1. The two halves of the multi-capsule package are thus locked in a closed position so that no additional outer packaging or time is required.
If desired, in the case of weak capsule base members or heavy parts packaged in the individual capsules, the tabs 18 and 20 are provided in conjunction with the extension 30 on tab 20 and the slot in tab- 18 for receiving the extension 30 to aid in the locking of the two halves of the packaging structure 10 illustrated in FIG- URE 1 in the closed position.
In the modified form of multi-capsule packaging structure illustrated in FIGURE 3, elements similar to elements of packaging structure 10 have been given similar reference characters. The packaging structure illustrated in FIGURE 3 differs from that illustrated in FIGURE 1 only in that the pockets 14 of base members 12 have been produced with substantially no draft angle so that a greater force will be required to close the package of FIGURE 3. The locking action of the nested individual capsules of the package of FIGURE 3 is thereby increased as is the necessity for deforming the individual capsules in closing the modified packaging structure. No locking tabs 18 and 20 are therefore required with the package of FIGURE 3. This is particularly true since the connecting portion 22 of the packaging structure of FIGURE 3 is in surface to surface engagement with one end pocket 14 of one of the base members 12 in the closed packaging structure as shown to enhance the locking characteristics of the rectangular cross-sections.
In the further modification of the packaging structure 10 illustrated in FIGURE 4, similar reference characters have again been placed'on similar elements. The pockets 14 have, however, again been altered sothat the longitudinally spaced apart transversely extending sides thereof converge outwardly of the cover sheet as shown in FIGURE 4 to again increase the locking action between the individual nested capsules with the packaging structure closed.
Further the transversely extending longitudinally spaced apart edge portions 34 of the pockets in the package of FIGURE 4 have been constructed to converge outwardly of the cover sheet to insure proper deformation of the capsules on closing of the package illustrated in FIGURE 4. Again no closing tabs are needed and the connecting portion 22 of the cover sheet 16 is formed to closely receive the end pocket 14.
The separate elements of the further modified packaging structure illustrated in FIGURES 5 through 7 have also been given reference characters similar to the reference characters used for the same elements in the packaging structure of FIGURE 1. In the modification of the invention illustrated in FIGURES 5 through 7 the cover sheet 16 is, however, provided with separate portions 34 at each end on one side thereof having openings 36 therethrough. The portions 34 may be folded over the base members 12 positioned as illustrated in FIGURE 1 0n the cover sheet with the pockets 14 extending through the openings 36 before the base members 12 are sealed to the cover sheet so that a sandwich construction illustrated best in FIGURE 6 is produced. Such construction provides additional rigidity for the cover sheet which is desirable to maintain the locking relation of the nested capsules.
While one embodiment of the present invention and modifications thereof have been disclosed, other modifications and embodiments are contemplated. Thus the cover sheet may be secured to the base members by means other than bonding with heat and pressure, the cover sheet may be plastic or plastic coated paper board and the base sheet may be other than clear plastic. It is the intention to include all embodiments and modifications of the invention as are defined by the appended claims within the scope of the invention.
What I claim as my invention is:
