INVENTOR. DANFORTH HOLLEY ATTORNEYS PACKAGE STRUCTURE,

BACKGROUND or THE INVENTION 1. Field of the Invention I The invention relates to package structure and refersmore specifically to folding package structure which may be constructed of plastic and includes integral nipple and recessmechanical means for securing the package structure closed, and a triangular, particularly rigid hinge portion located between a pair of body portions, each of which has'inclined edges to add rigidity to the package structure and facilitate stacking of a plurality of separate package structures.

2. Description of the Prior Art Prior package structures have included a plurality of different means for closing the structures to insure articles packaged therein remain in the packaged structure until it is desired to remove them therefrom. In'the-case of prior paper or cardboard packaged slots, tabs,adhesives, tape and the like have been used to close the packages. Plastic packages have often been heat sealed. Thus, in the prior package structure closing of the packages has usually required separate closing cludea centrally located hub 42 surrounding a recess 44 havelements, such as adhesive, tape or thelike or'separate production operations, such as slotting and heat sealing which have made prior package structures more expensive than A necessary.

In addition, hinge structure of previous folding packages has generally included a single thickness of material across which a fold line is provided which hinge sti'ucture is not as strong or rigid as necessary for many applications'Furthcr, with many prior package structures, interlocked stacking'of the packages has not been possible.

SUMMARY OF THE INVENTION In accordance with the present invention there is provided a folding package construction comprising a pair of body 'portions each having a recess therein for receiving an article. The

package structure further includes an extremely rigid triangu lar hinge portion which is connected to adjacent edges of the body portions to allow the body portions -to pivot or foldtoward each other to close the package structure. The body portions have'inclined edges which provide packagerigidity and aid in stacking a plurality of packages. The package structure also includes a nipple and recess on theinner side of each body member cooperable to provide a snap lock on closing of the package.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a folding package structure constructed in accordance with the invention.

FIG. 2 is a side elevation view of the package structure illus-' trated in FIG. 1 in the closed position and including one of the 1 FIG. 4 is a partial section view of the hinge portion of the package structure of FIG. 1 illustrating one of the body portions slightly open.

FIG. 5 is an enlarged section view of one of the locking nipples and-recesses of the package structure of FIGS. I through 4 taken substantially on line 3-3 inFlG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT The folding one-piece package structure 10 illustrated best in FIG. 1 includes body portions 12 and 14 having edges 16- and 18 and including recesses 21 and 22 for receiving an article, such as a gear or the like therein. A hinge portion.'20 is connected between adjacent edges 16 and 18 of the body portions 12 and 14. The body portions 12 and 14 each include 2 locking means such as nipple 26 and recess 28'cooperating with each other with the nipple 26 received in the recess 28 to provide a snap lock upon closure of the package'structure 10.

The'edges l6 and 18 of thebody portions 12 and 14 include 3 the inner wall 30, an uppersurface 32 and outer wall 34. Abutments 37 extend inwardly of the inner walls 30 for engaging the article-placed in the packages. The outer'walls 34 are inclined outwardlyfrom the surface 32 to increase the rigidity FIGS. 1, 2 and 4. The hinge portion 20 of the package structure 10 has a triangular cross section including inclined sides 36' and 38 and also has end walls 40 which are also inclined to increase the'rigidity of the hinge portion 20. The hinge 20 allows the body portions 12 and'14 to pivot or fold toward each other to close the package structure 10. Furthermore, the outer sidewalls 34 at the hinge portion 20 have a sufficient incline to allow the sidewalls 34, 36 and 38 to abut one another when the plastic package structure 10 is closed.

The recesses 21 and 22 in'the body portions 12 and 14 ining a bottom 46 and a vertical wall 48. The flat annular surface 50 and sidewall 52 cooperate with wall 48 to form hub 42. The recess 44 of hub'42 is equal to the depth of body portions 12 and I4 and provides support for the package structure 10 when stacked in a horizontal position. The flat annular surfaces 50of the hubs 42 abut one another when the body portions'are folded to close the package structure 10. Therefore, th'e'centrally located hub 42 provides support centrally of the package structure 10. Furthermore, the recess 44 of hub 42 provides additional space for packaging bolts, screws or the I like useful with a packaged article. Also, body portions 12 and include corner recesses 54 for additional packaging areas if required.

l, The nipple 26 and recess 28 are also provided on the body portions 12 and I4 cooperating with one another when the body portions'are closed to lock the package structure 10 closed. As shown best in FIG. 5 recess 28 has an initial inner diameter slightly smaller than the outer circumference of nipple 26; Therefore, when the nipple is received within the recess 28, the diameter of the recess 28 has a tendency to fit snugly aboutthe nipple and to indent the nipple adjacent the flat surface 32. Therefore, when the nipple 26 is received within the recess 28 a snap lock is provided to secure the package structure in a closed position.

The package structure 10 may be made out of plastic, such as cellulose acetate, cellulose acetate butyrate or polyethylene compounds. The material used should be capable of being vacuum formed.

- A heat-sealing process is not necessary to close package structure IObecause of the snap lock means. Therefore, when the package is finished, an article is placed within the recess and the body members 12 and 14 are pivoted closed and the nipples are forced into the recesses to secure the article within the package structure 10.

What I claim as my invention is:

l. A folding one-piece package structure comprising a pair of rectangular body portions each having four edges and an inside side and an-outside side, each of the/edges of each body portion converging from the outside side toward the inside side, recesses in each body portion extending from the inside side toward the outside sidefor receiving articles to be packaged, a hinge portion extending longitudinally of adjacent one edges of the body portions and connected thereto by an "integ'ralflexible hinge, saidhinge portion having a triangular cross section, and triangular end parts for imparting rigidity to the'hinge portion inclined toward each other and from the outside side toward the inside side of the body portions at substantially the same angle as the two edges of the body portions perpendicular to the one edges thereof and adjacent thereto are and inclined toward the inside side of the body portions, saidinclined one edge of each of the body portions and said hinge structure effecting a corner at each one edge of the body portions with the body portions positioned over each other by folding the one-piece package structure at the two means integral with the package structure for securing the body portions of the package structure together with the inside sides of the body portions in surface-to-surface contact.
