Abstract

A clamshell type container for dispensing paper having upper and lower hingedly connected portions. The container may be transparent, and may enclose a conventional box of wax paper or plastic wrap for dispensing. A safety front edge protects the user against cuts when cutting the dispensed paper. A resiliently-biased releasable locking mechanism holds the container in a closed position.

Claims

1. A clamshell type container for storing a conventional box of rolled sheet material and for dispensing said rolled sheet material from said box, comprising:

an upper container portion comprising a top wall and a front wall;

a lower container portion comprising a bottom wall and a back wall, said back wall of said lower container portion being hingedly interconnected to said top wall of said upper container portion;

side wall members comprising first side wall members provided respectively at opposite ends of said upper container portion, and second side wall members provided respectively at opposite ends of said lower container portion;

said first and second side wall members being disposed in substantially overlapping relation to each other in said closed position of said container;

said upper container portion, said lower container portion, and said side wall members being fabricated of a substantially rigid material and together forming an enclosure shaped and dimensioned to closely receive therein said conventional box of rolled sheet material;

means for releasably locking said upper container portion and said lower container portion in a closed position, said locking means being disposed on said side wall members;

said locking means comprising a resiliently-biased locking member provided on at least one of said side wall members, and means for engaging said locking member provided on a corresponding side wall member disposed in substantially overlapping relation to said at least one side wall member in said closed position of said container;

said engaging means comprising a side wall edge portion which urges said locking member inwardly as said container is being closed, and a contiguous arcuate concave portion of said side wall within which said locking member automatically seats when said container is in said closed position;

said upper container portion and said lower container portion when in said closed position forming a predetermined aperture between a lower edge portion of said front wall and a forward edge portion of said bottom wall through which at least a portion of said sheet material is extended when said conventional box of rolled sheet material is operably disposed in said container; and

means for cutting said sheet material, said cutting means being disposed adjacent said predetermined aperture and along said lower edge portion of said front wall.

2. A clamshell type container according to claim 1, wherein:

an inner surface portion of said front wall contacts a front surface of said conventional box of rolled sheet material when said box is operably disposed within said container.

3. A clamshell type container according to claim 1, wherein:

said cutting means comprises a serrated cutting portion provided along an inner lower edge portion of said front wall; and

a substantially smooth safety edge is provided along an outer lower edge portion of said front wall, adjacent said serrated cutting edge.

4. A clamshell type container according to claim 3, wherein:

said serrated cutting portion comprises a series of teeth which are tapered from a maximum dimension of said teeth at an inner surface of said front wall lower edge portion to a minimum dimension of said teeth adjacent said smooth safety edge.

5. A clamshell type container according to claim 1, wherein:

one of said resiliently-biased locking members is provided on each of said second side wall members, each said locking member being biased outwardly;

said engaging means is provided on each of said first side wall members.

6. A clamshell type container according to claim 5, wherein:

said cutting means comprises a serrated cutting portion provided along an inner lower edge portion of said front wall;

a substantially smooth safety edge is provided along an outer lower edge portion of said front wall, adjacent said serrated cutting edge; and

said serrated cutting portion comprises a series of teeth which are tapered from a maximum dimension of said teeth at an inner surface of said front wall lower edge portion to a minimum dimension of said teeth adjacent said smooth safety edge.

7. A clamshell type container according to claim 6, wherein:

said upper container portion, said lower container portion, said side wall members, and said cutting means are fabricated of a substantially rigid, transparent material.

8. A container for mounting a conventional box of rolled sheet material to an external surface, and for dispensing said rolled sheet material from said box, comprising:

an upper container portion comprising a top wall and a front wall;

a lower container portion comprising a bottom wall and a back wall, said back wall of said lower container portion being hingedly interconnected to said top wall of said upper container portion;

side wall members provided at respective ends of at least one of said upper and lower container portions;

said upper container portion, said lower container portion, and said side wall members being fabricated of a rigid unbendable material and together forming a substantially rectangular parallelepiped enclosure shaped and dimensioned to closely receive therein said conventional box of rolled sheet material;

means for releasably locking said upper container portion and said lower container portion in a closed position, said locking means being disposed on said side wall members;

said upper container portion and said lower container portion when in said closed position forming a predetermined aperture between a lower edge portion of said front wall and a forward edge portion of said bottom wall through which at least a portion of said sheet material is extended when said conventional box of rolled sheet material is operably disposed in said container;

means for cutting said sheet material, said cutting means being disposed adjacent said predetermined aperture and along said lower edge portion of said front wall;

means for mounting said container to an external surface, said mounting means being provided on a rigid unbendable portion of said container substantially distal from said cutting means;

said mounting means comprising a plurality of holes formed in at least one wall of said container;

said cutting means comprising a serrated cutting portion provided along an inner lower edge portion of said front wall;

a substantially smooth safety edge being provided along an outer lower edge portion of said front wall, adjacent said serrated cutting edge;

said serrated cutting portion comprising a series of teeth which are tapered from a maximum dimension of said teeth at an inner surface of said front wall lower edge portion to a minimum dimension of said teeth adjacent said smooth safety edge;

said side wall members comprising first side wall members provided respectively at opposite ends of said upper container portion, and second side wall members provided respectively at opposite ends of said lower container portion;

said first and second side wall members being disposed in substantially overlapping relation to each other in said closed position of said container;

said locking means comprising a resiliently-biased locking member provided on at least one of said side wall members, and means for engaging said locking member provided on a corresponding side wall member disposed in substantially overlapping relation to said at least one side wall member in said closed position of said container;

one of said resiliently-biased locking members being provided on each of said second side wall members, each said locking member being biased outwardly;

said engaging means being provided on each of said first side wall members; and

each said engaging means comprising a side wall edge portion which urges said locking member inwardly as said container is being closed, and a contiguous arcuate concave portion of said side wall within which said locking member automatically seats when said container is in said closed position.
