Abstract

A tamper-resistant container with tamper evident feature which includes a base and lid joined by a flexible hinge having a tamper evident tab. The base and a lid are hingedly connected to each other via a hinge part and so interlocked form-locking latched that in the closed state. The hinge consists of a flat in the open state of the package, in which a substantially U-shaped tab separating lines of weakness to the outer edge of the flat area.

Claims (25)

1. A tamper-resistant container comprising:

a base;

a lid coupled to the base;

a flexible hinge having a base hinge portion and a lid hinge portion with a tamper evidence tab, and upper and lower hinge lines;

a line of weakness coupled to the tamper evidence tab connecting the lid hinge portion and the base hinge portion;

wherein when the lid is folded toward the base, the upper and lower hinge lines fold and the tamper evidence tab extends in a downward direction from the upper hinge line, wherein the downward position of the tamper evidence tab allows opening of the container by pulling the tamper evidence tab away from the package to separate the flexible hinge along the lines of weakness showing evidence of tampering.

2. The container of claim 1 , wherein separating the hinge along the lines of weakness results in separation of the lid from the base.

3. The container of claim 1 , wherein the base includes upright side walls, rear wall and front wall and a bottom forming a cavity.

4. The container of claim 1 , wherein the base includes a base edge, and the lid includes a lid edge being configured to couple with the base edge in a closed position.

5. The container of claim 1 , wherein the flexible hinge consists of a flat area in the open position.

6. The container of claim 5 , wherein the tamper evidence tab is coupled with lines of weakness from the tamper evidence tab to outer edges of the flat area.

7. The container of claim 1 , wherein the hinge is preferably formed integrally with both base and lid such that the base and lid are a single continuous piece of material formed simultaneously.

8. The container of claim 1 , wherein the hinge is proximate a rear wall.

9. The container of claim 1 , wherein a lid edge sits below a base edge so that the lid cannot be opened using the lid edge.

10. A container having a tamper evidence tab comprising:

a base having a base edge;

a lid having a lid edge, the lid edge being configured to couple with the base edge in a closed position;

the base edge and lid edge are hingedly connected to each other via a flexible hinge, wherein the flexible hinge consists of a base hinge portion and a lid hinge portion, and upper and lower hinge lines and is a flat area in the open position, the flexible hinge having a substantially U-shaped tamper evidence tab extending in a downward position from the upper hinge line and coupled with lines of weakness from the tamper evidence tab to outer edges of the flat area, so that when the downward tamper evidence tab is grasped and pulled away from the package showing evidence of tampering, the lines of weakness between the base edge and lid edge are torn allowing opening of the lid.

11. The container of claim 10 , wherein the base includes upright side walls, rear wall and front wall and a bottom forming a cavity.

12. The container of claim 10 , wherein the lid edge sits below the base edge so that the lid cannot be opened using the lid edge.

13. A tamper-resistant container comprising:

a base having upright side walls, rear wall and front wall extending between a bottom and base edge forming a cavity;

a lid having a top lid portion and a lid edge, the lid edge configured to couple with the base edge in a closed position;

the base and lid are hingedly connected to each other via a flexible hinge, wherein the hinge consists of a base hinge portion and a lid hinge portion, and upper and lower hinge lines and is a flat area in the open position, the hinge having a substantially U-shaped tamper evidence tab coupled with lines of weakness from the tamper evidence tab to an outer edge of the flat portion, so that when closing the plastic lid the tamper evidence tab extends in a downward position from the upper hinge line which can be grasped and pulled away from the package showing evidence of tampering for opening the lid.

14. The container of claim 13 , wherein the lid edge sits below the base edge so that the lid cannot be opened using the lid edge.
