Abstract

A recloseable container is preferably produced by thermoforming. The container has an elongated shape with a dispensing nozzle at one end. Above the dispensing nozzle is a tab. When this tab is broken off the container, the nozzle is opened. Adjacent the nozzle is a hinged closure. The hinged closure has a shape complementary to that of the nozzle and can be rotated on the hinge to overlap and close the container nozzle. There is an arrangement to lock the closure in a nozzle closing orientation and an arrangement to provide an air and liquid seal to the nozzle.

Claims

1. A reclosable container comprising a container body, a planar border at least partially surrounding said container body said container body sealed at one end and having an openable dispensing means at another end;

a first breakaway means disposed above said dispensing means and closing said dispensing means;

a hinged closure means laterally adjacent said dispensing means and attached to said container body by a hinge, said hinged closure means having an upper portion and a lower portion, said upper portion offset from said lower portion and connected to said lower portion by a lateral groove, said hinged closure means rotating on said hinge to overlap and reclose said dispensing means after said first breakaway means has been removed.

2. A reclosable container as in claim 1 wherein said container is a thermoformed container.

3. A recloseable container as in claim 1 wherein said hinged closure means has a section with a shape complementary to that of said dispensing means.

4. A reclosable container as in claim 1 wherein said hinged closure means additionally is attached to said container body by a second breakaway means whereby after severing said second breakaway means said hinged closure means is able to be rotated on said hinge to close said dispensing means.

5. A recloseable container as in claim 1 wherein said dispensing means and said hinged closure means have cooperating liquid seal means.

6. A recloseable container as in claim 5 wherein said cooperating liquid seal means comprises an interfitting rib and groove arrangement.

7. A reclosable container comprising a container body sealed at one end and having an openable dispensing means at another end;

a planar border at least partially surrounding said container body, a first breakaway means disposed above said dispensing means and closing said dispensing means;

a hinged closure means laterally adjacent said dispensing means and attached to said planar border by a hinge, said hinged closure means rotating on said hinge to overlap and close said dispensing means after said first breakaway means has been removed, and a lateral groove on said hinged closure such that when such hinged closure means is rotated to reclose said dispensing means a portion of said planar border enters into said lateral groove to latch said hinged closure.

8. A recloseable container as in claim 7 wherein said hinged closure means has a section with a shape complementary to that of said dispensing means.

9. A recloseable container as in claim 7 wherein said hinged closure means has a locking means to lock said hinged closure means to close said dispensing means.

10. A recloseable container as in claim 9 wherein there is a planar border surrounding said container body, said border has a locking means to accept the locking means of said hinged closure means.

11. A recloseable container as in claim 10 wherein said border locking means and said hinged closure locking means comprise a mating pin and aperture.

12. A recloseable container as in claim 7 wherein said container is a thermoformed container.

13. A recloseable container as in claim 7 wherein said dispensing means and said hinged closure means have cooperating liquid seal means.

14. A recloseable container as in claim 13 wherein said cooperating liquid seal means comprises an interfitting rib and groove arrangement.

15. A reclosable container comprising a container body, a planar border at least partially surrounding said container body, said container body sealed at one end and having an openable dispensing means at another end;

a first breakaway means disposed above said dispensing means and closing said dispensing means;

a hinged closure means laterally adjacent said dispensing means and attached to said container body by a hinge, said hinged closure means rotating on said hinge to overlap and reclose said dispensing means, said hinged closure means having a locking means to lock said hinged closure means, a cooperating locking means on said planar border, whereby said hinged closure means secures said dispensing means after said first breakaway means has been removed.

16. A recloseable container as in claim 15 wherein said border locking means and said hinged closure locking means comprise a mating pin and aperture.

17. A reclosable container comprising a thermoformed container having a container body, said container body sealed at one end and having an openable dispensing means at another end;

a first breakaway means disposed above said dispensing means and closing said dispensing means;

a hinged closure means laterally and sidewise adjacent said dispensing means and attached to said container body by a hinge, said hinged closure means is able to be rotated on said hinge to overlap and reclose said dispensing means after said first breakaway means has been removed, a second breakaway means on a lower end of said hinged closure means and attaching said hinged closure means to said planar border whereby said hinged closure means cannot be rotated on said hinge until said second breakaway means is severed.
