Abstract

An easily closable and open able container system includes a number of features which facilitate easy opening and closing while maintaining a high seal, which will give a feedback to the user to let the user know that a seal is formed. A circumferentially inwardly disposed angled groove is formed on the inside the opening of a container. A complementary angled projection is formed on the circumferentially outwardly disposed surface of the lid for fitting into the circumferentially inwardly disposed angled groove formed on the inside the opening of a container.

Claims

1. A sealable container comprising:

a base container having a bottom and a wall which includes a circumferentially inwardly directed groove, an inner wall, a top wall and an outer downwardly extending wall;

a lid having a main planar extent, an upwardly extending inner rim portion, a middle rim portion and an outer downwardly extending rim portion, a circumferentially outwardly disposed projection adjacent a wall of the inner rim portion and extending in a direction of the outer downwardly extending rim portion and complementary to the groove of the base wall.

2. The sealable container as recited in claim 1 and wherein said inner wall is angled with respect to said outer downwardly extending wall.

3. The sealable container as recited in claim 2 wherein the angle of said inner wall with respect to said outer downwardly extending wall is from about five to about ten degrees.

4. The sealable container as recited in claim 1 and wherein said upwardly extending inner rim portion is angled with respect to said outer downwardly extending rim portion.

5. The sealable container as recited in claim 4 wherein the angle of said upwardly extending inner rim portion with respect to said outer downwardly extending rim portion is from about five to about ten degrees.

6. The sealable container as recited in claim 4 wherein said circumferentially outwardly disposed projection of said lid has a pair of oppositely disposed angled surfaces having an angle of from about eighty to about ninety degrees with respect to each other.

7. The sealable container as recited in claim 6 wherein said pair of oppositely disposed angled surfaces meet at a common edge.

8. The sealable container as recited in claim 1 wherein said inner wall, a top wall and an outer downwardly extending wall, form an extended seal with respect to said inner rim portion, said middle rim portion and said outer downwardly extending rim portion when said lid is attached to said base container.
