Abstract

Abstract An improved one-piece reusable container is formed from transparent plastic. The lid of the container is clear and transparent with no distortion for easy viewing of the contents. The sides of the container chamber are slanted inward to allow nesting of the containers during shipping. The container is semi-rigid with good structural integrity; and will not deform during normal handling and usage. The container has a latch to insure that it will not open during shipping and display, but will only open when the lid and chamber are pulled apart in a predetermined manner.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 193 words
A container formed from a single piece of transparent, moldable sheet material, which comprises: (a) a first body member having a first, flat, elongaged flange a protruding, flat, smooth surface substantially parallel to said flange, and a female mating region between said flange and said surface; (b) a second body member having a second, flat, elongated flange a raised channel formed within said second flange having an inside sidewall and an outside sidewall a male mating region which is formed on the outermost surface of said outside sidewall of said raised channel, said male mating region cooperating with said female mating region during closure of said container, and a recessed chamber formed within the innermost surface of said inside sidewall of said raised channel, said recessed chamber having a second recessed area extending from a first recessed area; (c) an integral hinge connecting said first body member to said second body member, said hinge enabling said container to open and close; and (d) a latching means having a first depression located along said male mating region which fits into a second depression located along said female mating region during closure of said container.
Claim 2
Dependent Claim 193 words
A container formed from a single piece of transparent, moldable sheet material, which comprises: (a) a first body member having a first, flat, elongaged flange a protruding, flat, smooth surface substantially parallel to said flange, and a female mating region between said flange and said surface; (b) a second body member having a second, flat, elongated flange a raised channel formed within said second flange having an inside sidewall and an outside sidewall a male mating region which is formed on the outermost surface of said outside sidewall of said raised channel, said male mating region cooperating with said female mating region during closure of said container, and a recessed chamber formed within the innermost surface of said inside sidewall of said raised channel, said recessed chamber having a second recessed area extending from a first recessed area; (c) an integral hinge connecting said first body member to said second body member, said hinge enabling said container to open and close; and (d) a latching means having a first depression located along said male mating region which fits into a second depression located along said female mating region during closure of said container.
Claim 3
Dependent Claim 16 words
The structure of claim 1, wherein said inside sidewall of said raised channel is slanted inward.
Claim 4
Dependent Claim 21 words
The structure of claim 1, wherein the area of said first depression is less than the area of said second depression.
Claim 5
Dependent Claim 16 words
The structure of claim 1, wherein said first depression is deepest adjacent to said first flange.
Claim 6
Dependent Claim 16 words
The structure of claim 4, wherein said second depression is deepest adjacent to said second flange.
Claim 7
Dependent Claim 30 words
The structure of claim 1, wherein said first and said second depressions are located on said female mating region and said male mating region respectively most remote from said hinge.
Claim 8
Dependent Claim 59 words
The structure of claim 2, wherein said outside sidewall of said raised channel is slanted outward such that when a plurality of like dimensioned containers are stacked said inside sidewall and said outside sidewall of said raised channel member will insert into the corresponding channel member of an adjacent like dimensioned stacked container thereby releasably locking said containers together.
Claim 9
Dependent Claim 34 words
The structure of claim 7, further comprising a peripheral shoulder integrally formed with and extending inwardly from said inside sidewall where said peripheral shoulder is spaced from the plane of said second elongated flange.
Claim 10
Dependent Claim 41 words
The structure of claim 8, wherein said second recessed area has less inward taper than said first recessed area such that said peripheral shoulder of a like dimensioned container will bear against said second recess area during stacking of adjacent containers.
Claim 11
Dependent Claim 162 words
An improved container of the type formed of a single piece of transparent moldable resilient sheet material having a nesting axis, an integral hinge connecting a lid member to a chamber member where said lid member has a peripheral female mating surface extending from a first flat elongated flange, and where said chamber member has a second elongated flange, a chamber recess defined by a bottom wall and peripherally extending sidewall, and a raised U-shaped peripheral channel having inside and outside sidewalls and a topwall which define a continuous peripheral opening in said second flange where the inside sidewall of said U-shaped channel is an integral part of said peripherally extending sidewall of said chamber recess and where the outermost surface of the outside sidewall of said channel forms a male mating surface, the improvement comprising a lid depression contained with said female mating surface such that upon closure of said lid member sid lid depression bears upon said female mating surface.
Claim 12
Dependent Claim 162 words
An improved container of the type formed of a single piece of transparent moldable resilient sheet material having a nesting axis, an integral hinge connecting a lid member to a chamber member where said lid member has a peripheral female mating surface extending from a first flat elongated flange, and where said chamber member has a second elongated flange, a chamber recess defined by a bottom wall and peripherally extending sidewall, and a raised U-shaped peripheral channel having inside and outside sidewalls and a topwall which define a continuous peripheral opening in said second flange where the inside sidewall of said U-shaped channel is an integral part of said peripherally extending sidewall of said chamber recess and where the outermost surface of the outside sidewall of said channel forms a male mating surface, the improvement comprising a lid depression contained with said female mating surface such that upon closure of said lid member sid lid depression bears upon said female mating surface.
Claim 13
Dependent Claim 34 words
The improved container of claim 10, wherein said male mating surface is flat and continuous and said lid depression has a latch bearing surface for biasing said lid member against said male mating surface.
Claim 14
Dependent Claim 65 words
The improved container of claim 11, wherein said outside sidewall of said raised channel tapers outwardly and said inside sidewall of said raised channel tapers inwardly such that when a plurality of like dimensioned containers are stacked said inside sidewall and said outside sidewall will insert into the corresponding raised channel member of an adjacent like dimensioned stacked container thereby releasably locking said containers together.
Claim 15
Dependent Claim 20 words
The improved container of claim 12, wherein said peripherally extending sidewall of said chamber recess is continuous and tapers inwardly.
Claim 16

Claim 18
Dependent Claim 27 words
The improved container of claim 10, wherein said female mating surface contains a chamber depression which captively holds said lid depression during closure of said lid member.
Claim 19
Dependent Claim 65 words
The improved container of claim 16, wherein said outside sidewall of said raised channel tapers outwardly and said inside sidewall of said raised channel tapers inwardly such that when a plurality of like dimensioned containers are stacked said inside sidewall and said outside sidewall will insert into the corresponding raised channel member of an adjacent like dimensioned stacked container thereby releasably locking said containers together.
Claim 20
Dependent Claim 20 words
