Abstract
Abstract A resealable container includes a generally planar, integrally formed base such as of vacuum formed styrene having a plurality of depressions therein forming receptacles which extend outwardly from the plane on one side thereof and which have beaded portions extending outwardly on the opposite side of the plane to form the open ends of the receptacles. The container also includes a generally planar, integrally formed cover, also of vacuum formed sytrene or similar material, which is mounted on the base so that a plurality of shallow depressions in the cover extend into the various receptacles of the base. Individual lids defined by die cut scorings in the cover and which include the various shallow depressions therein are preferably sealed to the beaded portions of the receptacles such as by use of an appropriate adhesive to form an air-tight enclosure where they remain as the remainder of the cover is pulled away. Thereafter the lids are peeled away from the various receptacles to provide access thereto, after which the lids can again be inserted into the beaded portions of the receptacles to reseal the receptacles by virtue of an interference fit therewith.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
88 words
A container comprising the combination of: an integrally formed base member having a plurality of depressions therein defining encloseable receptacles; and an integrally formed cover member adapted to be matingly fitted to and generally coextensive with the base member and having a pattern of perforations therein dividing the cover member into a plurality of lids joined by remaining portions of the cover member, the lids forming covers for and remaining with the receptacles in the base member upon removal of the remaining portions of the cover member therefrom.
Claim 2
Dependent Claim
88 words
A container comprising the combination of: an integrally formed base member having a plurality of depressions therein defining encloseable receptacles; and an integrally formed cover member adapted to be matingly fitted to and generally coextensive with the base member and having a pattern of perforations therein dividing the cover member into a plurality of lids joined by remaining portions of the cover member, the lids forming covers for and remaining with the receptacles in the base member upon removal of the remaining portions of the cover member therefrom.
Claim 3
Dependent Claim
49 words
A container in accordance with claim 1, wherein the cover member includes a plurality of shallow depressions therein, each of which forms a central part of a different one of the lids and extends into the interior of the associated receptacle wiTh the lid in place over the receptacle.
Claim 4
Dependent Claim
50 words
A container in accordance with claim 2, wherein each of the lids is chemically and peelably sealed to the associated receptacle, and each of the shallow depressions in the cover member is slightly larger in size than the associated receptacle providing an interference fit therewith and a mechanical seal thereof.
Claim 5
Dependent Claim
161 words
A multi-receptacle container, having a plurality of individual receptacles which are individually resealable, comprising: a generally planar, integrally formed base having a plurality of depressions therein extending outwardly from the plane of the base on one side thereof to form the individual receptacles and which extend outwardly from the plane of the base on the other side thereof to form beaded open ends of the receptacles; and a generally planar, integrally formed cover disposed generally parallel to the base and including a plurality of shallow depressions therein, each of the shallow depressions being configured to and extending into the beaded open end of a different one of the receptacles to form a mechanical seal therewith, the cover being scored in a selected pattern to define a plurality of lids which are separable from the rest of the cover, each of the lids including one of the shallow depressions in the cover and being chemically and peelably sealed to the associated receptacle.
Claim 6
Dependent Claim
161 words
A multi-receptacle container, having a plurality of individual receptacles which are individually resealable, comprising: a generally planar, integrally formed base having a plurality of depressions therein extending outwardly from the plane of the base on one side thereof to form the individual receptacles and which extend outwardly from the plane of the base on the other side thereof to form beaded open ends of the receptacles; and a generally planar, integrally formed cover disposed generally parallel to the base and including a plurality of shallow depressions therein, each of the shallow depressions being configured to and extending into the beaded open end of a different one of the receptacles to form a mechanical seal therewith, the cover being scored in a selected pattern to define a plurality of lids which are separable from the rest of the cover, each of the lids including one of the shallow depressions in the cover and being chemically and peelably sealed to the associated receptacle.
Claim 7
Dependent Claim
21 words
A multi-receptacle container in accordance with claim 4, wherein the base and the cover comprise thermoformed elements of generally plastic composition.
Claim 8
Dependent Claim
43 words
A multi-receptacle container in accordance with claim 4, wherein the chemical seal between each lid and the associated receptacle is provided by an adhesive disposed between the underside of the lid surrounding the shallow depression and the beaded open end of the receptacle.
Claim 9
Dependent Claim
49 words
A multi-receptacle container in accordance with claim 4, wherein the receptacles and the shallow depressions are generally cylindrical in configuration and the outside diameters of the shallow depressions are slightly larger than the inside diameters of the beaded open ends of the receptacles to form the mechanical seal therebetween.
Claim 10
Dependent Claim
24 words
A multi-receptacle container in accordance with claim 4, wherein each of the lids has a tab-like portion facilitating removal thereof from the associated receptacle.
Claim 11
Dependent Claim
30 words
A multi-receptacle container in accordance with claim 4, wherein each of the lids has a portion thereof which is sealed to the base to form a hinge for the lid.
Claim 12
Dependent Claim
72 words
A container comprising the combination of: an integrally formed base member having a plurality of depressions therein defining encloseable receptacles; and an integrally formed cover member adapted to be fitted to the base member and being readily separable along endless lines which encompass the depressions in the base member and which are separable from an interconnecting matrix comprising the remainder of the cover member to form individual lids for the encloseable receptacles.
Claim 13
Dependent Claim
72 words
A container comprising the combination of: an integrally formed base member having a plurality of depressions therein defining encloseable receptacles; and an integrally formed cover member adapted to be fitted to the base member and being readily separable along endless lines which encompass the depressions in the base member and which are separable from an interconnecting matrix comprising the remainder of the cover member to form individual lids for the encloseable receptacles.
Claim 14
Dependent Claim
110 words
A container comprising the combination of: an integrally formed, generally planar base member having a plurality of depressions therein extending outwardly from the plane of the base member on one side thereof to form receptacles and extending outwardly from the plane of the base member on the other side thereof to form raised open ends for the receptacles; and an integrally formed, generally planar cover member adapted to be disposed in generally parallel relation with and matingly fitted to the base member, said cover member having a pattern of perforations therein which define lids for the individual receptacles of the base member and which are detachable from the cover member.
