Lowrance Attorney-Pendleton, Neuman, Williams & Anderson ABSTRACT: A composite package is provided which includes an outer receptacle and an inner receptacle removably mounted therein. Means are provided on the walls of the outer receptacle whichmreleasably engage complemental means provided on the walls of the inner receptacle whereby the receptacles are retained in a predetermined assembled relation. The bottom of the outer receptacle is provided with a transversely extending ridge which forms said bottom into contiguous compartments. The ridge subtends and supportingly engages the inner receptacle when the latter is in the said predetermined assembled relation.

Qftentimes it is desirable to package together in a single compact 'unit various types of food'products (e.g., cheese spread and crackers), various types of chemical ingredients (e.g., two-part epoxy adhesives), various types of medical supplies (e.g., sterile compresses and ointment), or various other.

products (e.g., screwsand washers).

Packages for this general purpose have heretofore been pro- 13, if desired, may be formed of any of the aforementioned vided; however,"because of certain structural characteristics,

they have been beset with one or more of the following shortcomings; (a) the package was awkward to assemble and'handle;'(b) it was susceptible to pilferage or infestation; (c) it was costly and unattractive; and (d) it was incapable of retaining.

the accommodated'products in a segregatedstate even when the package was subjected to normal handling.

t SUMMARYQF THE INVENTION ."Thu's, itis an object of this invention to provide a composite package which is not beset with any of the aforenoted shortcomings. v K I It is a further object of this inventionto provide a composite packagcwhich is inexpensive'to produce, is easily loaded, and

isve'rsatile in accommodating a variety of products.

It is a still further object of this invention to provide a composite package, the components of which do not deleteriously affect the accommodated products.

Further and additional objects will appear from the tion, accompanying drawings and appended claims.

In' accordance with one embodiment of this, invention, a composite package is provided which includes an outer receptacle and an inner receptacle releasably mounted therein. The

outer receptacle hasa bottom delintited by upstanding walls. 7

The upper edgeportions .of the walls delimit an open top. Formed in the bottom of the outer. receptacle is a transversely extending ridge which separates said bottom into contiguous compartments. Opposed wall portions of the outer receptacle are provided with means which releasably engage complementalmeansprovided on the walls of the inner receptacle so as to retain the innenr'eceptacle in a predetermined assembled position with respect tothe outer receptacle. The inner receptacle," when .in its predetermined assembled position, rests upon 'the ridge formed in the outer. receptacle. The outer receptacle isjprovided with a cover which overlies the inner receptacle.

DESCRIPTION Fora more complete understanding of the invention 1 reference shouldbe made to the drawings wherein:

FIG. 1 isa'n explodedperspective view takenfromabove of one form 'of the improved composite packagel I Package 10, as illustrated, includes an elongated open top outer receptacle 11, aninner receptacle l2 remo vably disposed within receptacle l1, and'a removable cover or lid 13 which overlies both receptacles l1 and 12 and is secured to the upper end of receptacle 1]. If desired, the receptacles may be formed from vinyl polymers and copolymers; acrylonitrilebutadiene-styrene polymers, homopolymers and copolymers of styrene; polyethylene, polypropylene; copolymers of ethylene and butene, polybutene, homopolymers and copolymers of 4-methyl'l-butene, and polyamide. The cover polymers, or laminates of two'or more of said polymers, or

laminates of one or more of the said polymers and paper, or a metal foil.

The inner receptacle 12 may, if desired, be provided with a separate cover, not shown. Whethera separate cover is to be utilized will depend upon the types of products accommodated in the package; V

The outer receptacle '11 includes a bottom 14, and upwardly extending walls 15 delimiting same. The bottom is provided with a transverselyextending ridge 16 which intercom descrip- FIG. Sis a fragmentary left end elevational view of the.

nects opposed wall portions 15a; The ridge separates the bottom 14 into contiguous compartments A and B. The wall portions of the outer receptacle 11 adjacent compartment B are offset inwardly was to forma ledge or shoulder 17. The upper surfaces of the ledges l7 and ridge 16 are generally coplanar and thus, coact to provide a supporting surface for the bottom 18 of theinner receptacle 12 when the latter is in a predetermined assembled position with respect to outer receptacle 1], see FIGS.2and4. I

Spaced above the supporting surface of the ledges and ridge and formed in the adjacent wall portions of the outer receptacle 11 are elongated pockets20 which open toward the interi-- or ofthe outer receptacle, see FIGS. 1, 4 and llQThe pockets 20 are disposed adjacent the top of the receptacle.

"Formed .in the top surface of ridge 16 is an upwardly protruding stop or nub 21. The stop is adapted to engage an end of the inner receptacle 12 when the latter isin its assem bled position and prevents endwise or lateral movement in one direction of the inner receptacle 12 with respect to the outer receptacle 11. u v Y I The inner receptacle 12 is of simple construction and includes the bottom 18 and upwardly extending walls 22 which delimit said bottom. The upper-edges of the walls 22 terminate in an outwardly extending flange -23. Flange 23, as seen more clearly in FIGS. '10 and l lyhas an inverted substantially U- shape cross-sectional configuration. The lower end of the outer leg 23a of the flange 23-is turnedabruptly outwardly so as to form a lip 23b. A similarly shaped flange 24 is formed at the upper edge of the walls 15 forming a part of the outer receptacle 11. Both flanges 23 and 24 reenforce the upper edges of the respective receptacles 12 and 11.

The flange 24 serves as a means of securing the cover 13 in an overlying closing relation with respect to the open top of the outer receptacle 11. The height of the inner receptacle 12 is-suc'h that it will not interfere with the securing of the cover 13 on the outer receptacle 11. I

Cover 13, as seen in FIGS. .1 and 4, includes a flat top panel 25 suitable for having indicia formed on or a gummed label affixed to the exposed surface thereof. The periphery of panel 25 is delimited by a depending shoulder 26. The interior surfaces of the shoulder 26 engage the exterior surfaces of the leg 24a forming a part of flange 24. The lower edge of shoulder 26 is shaped so as to form an inwardly facing pocket 27 which is adapted to resiliently accommodate a lip 24b formed on flange 24, see FIG. 4. Because of the material of which the cover 13 is formed, the shoulder 26 and pocket 27 of the cover may be flexed so as to facilitate assembly or disassembly of the cover on the receptacle 11. Obviously, other means may be utilized to secure the cover in place, such as tape, adhesives, etc.

It will be noted in FIGS. 10 and 11 that the inner leg 240 of the flange 24 in the vicinity of pocket 20 is offset outwardly a slight amount with respect to the interior surface of the receptacle walls 15. This outward offsetting of the flange leg 24c facilitates sliding of the lip 23b of the inner receptacle flange 23 downwardly into the interior of the outer receptacle 11 until it snaps into locking engagement with the pocket 20 formed in the receptacle walls 15. As noted in FIG. 10, no pocket 20 is formed at the corners lla and 11b of the outer receptacle 11.

It will be noted in FIG. 2 that, when the inner receptacle 12 is in its predetermined assembled position, the bottom thereof 18 closes off the compartment B. Thus, if desired, the compartment B may accommodate a product which is different from that disposed in either receptacle 12 or compartment A of the outer receptacle 1]. The depth and shape of compartments A and B may vary from that shown and will depend upon the types of products to be accommodated therein. Furthermore, the bottom 14 of the outer receptacle 1] may be provided with more than one transversely extending ridge. The various components of the composite package 10 may be formed of like or different materials and again will depend upon the types of products to be accommodated and the esthetic appearance desired. Furthermore, various other types of locking means may be provided on the corresponding wall portions of the inner and outer receptacles. For example, an outwardly facing pocket might be formed on the walls of the inner receptacle which would resiliently accommodate an inwardly projecting protuberance formed on the interior surfaces of the outer receptacle walls.

Thus, it will be seen that a simple, inexpensive and efficient composite package has been provided which is adapted to accommodate a variety of products and retain the segregated status of the products while the components of the package are in assembled relation.

While several embodiments of the invention have heretofore been described, it is to be understood, of course, that the invention is not limited thereto, but further modifications are contemplated and it is intended by the appended claims to cover such modifications.
