Abstract

A container moldable from a resilient, semirigid plastic material includes a transparent cover member and an opaque base member. The cover member includes a depending peripheral skirt having an angled slot formed in the junction of the skirt with a wall of the cover. The base member includes an outwardly extending, generally horizontal tab insertable through the slot in the cover member. A ramp-shaped detent formed integral with the tab prevents removal of the cover from the base when the cover is opened and provides a hinged connection between the cover member and the base member.

Claims

1. A container moldable from a resilient, semirigid plastic material comprising:

a cover member having a depending peripheral skirt integral with the side walls of said cover;

a base member having an upstanding peripheral skirt integral with the side walls of said base and receivable within the depending skirt of said cover member;

one of said peripheral skirts having an angled slot therein at the juncture of said one of said peripheral skirts with one of said members; and

hinge means extending through said slot and outwardly from the other of said peripheral skirts for permitting opening pivotal movement of said cover member relative to said base member and preventing removal of said cover member from said base member when said cover is pivoted to an open position.

2. A container as defined by claim 1 wherein said hinge means comprises:

an outwardly directed horizontal tab having a width substantially the same as the length of said slot.

3. A container as defined by claim 2 wherein said hinge means further includes detent means secured to said tab and positioned for preventing removal of said cover member from said base member when said cover member is pivoted to a fully open position.

4. A container as defined by claim 1 wherein said hinge means is part of said upstanding peripheral skirt of said base member and said slot is defined by said depending skirt of said cover member.

5. A container as defined by claim 3 wherein said hinge means is part of said upstanding peripheral skirt of said base member and said slot is defined by said depending skirt of said cover member.

6. A container as defined by claim 5 wherein said detent means comprises a ramp-like member integral with the undersurface of said tab, said ramp-like member being angled downwardly towards said base and having a face portion engaging said depending peripheral skirt when said cover member is pivoted to an open position, said slot and said ramp being dimensioned so that said tab may be slipped through said slot when said cover is almost closed, but preventing removal of said cover from said slot when said cover is fully opened.

7. A container as defined by claim 6 wherein said depending peripheral skirt of said cover member includes an inwardly directed depression thereby defining a closing detent and said upwardly extending peripheral skirt includes an angled lip whereby said closing detent engages said lip and resists opening of said container.

8. A container moldable from a resilient, semirigid plastic material, comprising:

a cover member having a top portion integral with outwardly angled, downwardly directed side and end wall portions, said cover member further including an outwardly directed, substantially horizontal surface integral with at least a portion of one of said end walls and a depending, substantially vertical surface integral with the lateral edge of said horizontal surface thereby defining a junction, said junction having a slot extending through a portion thereof;

a base member having a bottom portion and upwardly directed side and end walls, said cover member being superimposable on said base member;

a tab extending substantially horizontally outwardly from the lateral edge of one of said base member end walls and dimensioned so as to be insertable through said slot; and

detent means extending outwardly from a surface of said tab for preventing removal of said cover from said base when said cover is pivoted to an open position, said cover being sufficiently resilient in the area of said slot to permit passage of said tab and said detent means through said slot for attachment of said cover member to said base member.

9. A container moldable from a resilient, semirigid plastic material as defined by claim 8 wherein said cover member is formed from a resilient semirigid transparent plastic material and said base member is formed from a high impact plastic material.

10. A container moldable from a resilient, semirigid plastic material as defined by claim 8 wherein said tab has a width dimension substantially equal to but slightly less than the length dimension of said slot.

11. A container moldable from a resilient, semirigid plastic material as defined by claim 10 wherein said slot has a transverse dimension substantially equal to but slightly greater than the thickness of said tab.

12. A container moldable from a resilient, semirigid plastic material as defined by claim 11 wherein said detent means extends outwardly from the lower face of said tab.

13. A container moldable from a resilient, semirigid plastic material as defined by claim 12 wherein said detent means comprises a projection having a ramp-like configuration including a planar portion angled downwardly towards said base member.

14. A container moldable from a resilient, semirigid plastic material as defined by claim 13 wherein said detent projection further includes a substantially vertical front wall portion integral with said angled planar portion, said wall portion spaced from said one of said base member end walls a distance slightly greater than the thickness of said substantially vertical surface of said cover member whereby when assembled, said cover member vertical surface is trapped between said detent means and said base member so that removal of said cover from said base is substantially prevented when said cover is in a fully open position.

15. A container moldable from a resilient, semirigid plastic material as defined by claim 11 wherein said detent means extends outwardly from the upper face of said tab.

16. A container moldable from a resilient, semirigid plastic material as defined by claim 15 wherein said detent means comprises a projection having a ramp-like configuration including a planar portion angled upwardly towards said cover member and a substantially vertical front wall portion integral with said planar portion whereby removal of said cover member from said base member is prevented when said cover is opened slightly but easily accomplished when said cover is fully opened.

17. A container moldable from a resilient, semirigid plastic material as defined by claim 14 wherein said substantially horizontal surface and said substantially vertical surface of said cover member extend around the entire periphery of said cover member integral with the end walls and side walls of said cover member.

18. A container moldable from a resilient, semirigid plastic material as defined by claim 16 wherein said substantially horizontal surface and said substantially vertical surface of said cover member extend around the entire periphery of said cover member integral with the end walls and side walls of said cover member.

19. A container moldable from a resilient, semirigid plastic material as defined by claim 17 wherein said vertical surface of said cover member includes an inwardly directed depression positioned opposite said slot and said base member includes an outwardly angled lip engageable by said depression to thereby resist opening movement of said cover with respect to said base.

20. A container moldable from a resilient, semirigid plastic material as defined by claim 18 wherein said vertical surface of said cover member includes an inwardly directed depression positioned opposite said slot and said base member includes an outwardly angled lip engageable by said depression to thereby resist opening movement of said cover with respect to said base.

21. A container moldable from a resilient, semirigid plastic material as defined by claim 19 wherein said cover is formed from a transparent, semirigid plastic material and said base member is formed from a high impact plastic material.

22. A container moldable from a resilient, semirigid plastic material as defined in claim 19 further including a pair of inwardly directed side depressions positioned on each side of said cover and defined by said vertical surface of said cover, and said outwardly angled lip of said base extends along the sides of said base and is engageable by said side depressions.
