Abstract
Abstract A unitary nestable reclosable container is formed from a thin-walled clear flexible plastic or the like and includes a box-like base forming a receptacle for screws, bolts, etc. A lid is integrally joined to the base by a hinge and includes a peripheral groove having walls releasably engaging substantially planar side walls of the base for providing a sturdy closure. The peripheral groove further provides a wall which releasably locks with an upper portion of the base end wall providing a specially designed reversed taper spaced from a lower end wall portion by a restraining shelf. Each side juncture between the lid and base is substantially within a plane provided by the side wall while a label placed across such juncture forms a reliable seal. The side walls and end walls have specially designed pre-established angular orientations with respect to the bottom portion so that a plurality of similarly constructed containers may be nested in a stack while further allowing each individual container to be placed in an upstanding position supported by the end wall and integral hinge.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
215 words
A reclosable container of thin flexible thermoformed plastic material comprising a rectangular container base having a generally flat bottom and planar sidewalls and front and rear end walls joining the sidewalls, a lid integrally hinged to the rear end wall and movable between open and closed positions to provide a top portion for closing and strengthening the container base, the lid having a peripheral generally V-shaped groove extending downwardly from the plane of the lid and defined by inner and outer walls joined along the bottom of the groove providing a lateral stiffening member for the lid and the container base, the outer groove wall being shaped and engaging the top inner portions of the sidewalls and end walls when the lid is in its closed position to support them against inward flexing and bending and provide a sturdy container construction, the lid having a horizontal flange in the plane of the lid overlying the top edges of the sidewalls without extending outward substantially beyond the plane of the sidewalls providing a junction with the sidewalls substantially within the plane of the sidewalls to permit a label to be applied to the lid and at least one sidewall without substantial separation of the label from the plane of the sidewall to lockingly seal the container.
Claim 2
Dependent Claim
215 words
A reclosable container of thin flexible thermoformed plastic material comprising a rectangular container base having a generally flat bottom and planar sidewalls and front and rear end walls joining the sidewalls, a lid integrally hinged to the rear end wall and movable between open and closed positions to provide a top portion for closing and strengthening the container base, the lid having a peripheral generally V-shaped groove extending downwardly from the plane of the lid and defined by inner and outer walls joined along the bottom of the groove providing a lateral stiffening member for the lid and the container base, the outer groove wall being shaped and engaging the top inner portions of the sidewalls and end walls when the lid is in its closed position to support them against inward flexing and bending and provide a sturdy container construction, the lid having a horizontal flange in the plane of the lid overlying the top edges of the sidewalls without extending outward substantially beyond the plane of the sidewalls providing a junction with the sidewalls substantially within the plane of the sidewalls to permit a label to be applied to the lid and at least one sidewall without substantial separation of the label from the plane of the sidewall to lockingly seal the container.
Claim 3
Dependent Claim
28 words
The container of claim 1, wherein the top edges of the sidewalls are defined by bead-like lips of minimal horizontal extent substantially within the plane of the sidewalls.
Claim 4
Dependent Claim
28 words
The container of claim 1, wherein the upper portions of the groove walls are spaced to permit peripheral movement of a sharp instrument for peripherally severing the label.
Claim 5
Dependent Claim
37 words
The container of claim 1, wherein the front end wall includes a lower wall portion tapered upwardly and outwardly and an upper wall portion of reverse taper with a shelf joining the lower and upper wall portions.
Claim 6
Dependent Claim
46 words
The container of claim 4 wherein the lid outer groove wall extends forwardly adjacent to the front end wall to releasably engage the reverse taper upper wall portion of the front end wall when the lid is closed to form a releasable lock for the container.
Claim 7
Dependent Claim
44 words
The container of claim 4, wherein the taper of the lower wall portion is about ten degrees from the plane normal to the bottom, and the reverse taper of the upper wall portion is about five degrees from the plane normal to the bottom.
Claim 8
Dependent Claim
89 words
The container of claim 1, wherein the planar sidewalls are angularly orientated at a first angle in an outward direction with respect to a plane normal to the container base, the front end wall is angularly orientated at a second angle substantially greater than the first angle in an outward direction with respect to a plane normal to the container base and the rear end wall is substantially parallel to a plane normal to the container base for removably nesting the container with another container constructed in like manner.
Claim 9
Dependent Claim
86 words
The container of claim 1 wherein the lid includes a rear edge defined by the integral hinge connection of the lid to the upper edge of the rear end wall, the rear edge extending outwardly from the rear end wall when the lid is in its closed position to provide a mounting surface for the container when placed in an upstanding position supported by the mounting surface and a portion of the rear end wall adjacent a juncture between the base and the rear end wall.
Claim 10
Dependent Claim
51 words
The container of claim 1, wherein the lid includes a front edge releasably mating with an upper edge provided by the front end wall when the lid is in its closed position, the lid front edge including an outwardly extending projection providing means for supporting the container in a hanging position.
