Tamper evident container

Claim 2

A container adapted to securely engage a cover displaying a peripheral depending skirt, comprising: a body including side walls having an upper edge portion adapted to engage the peripheral depending skirt of a cover; said side walls including a peripheral flange consisting of a horizontal portion projecting outwardly from said side wall and of an outer vertical portion distanced from said side wall, said portions adapted to receive in close relationship therewithin a lower part of the skirt; and tab means having a horizontal portion integrally formed with said side wall and with said horizontal portion of said flange and a downwardly extending vertical portion integrally formed with said vertical portion of said flange; said horizontal and vertical portions of said tab means being connected to said horizontal and vertical portions of said flange through weakened areas to thereby render said tab means breakable when pressure is applied thereon thus providing visual indication of tampering, whether authorized or unauthorized, and adapted to allow removal of the cover from the container; wherein said downwardly extending vertical portion of said tab means includes an enlarged area relative to said vertical portion of said flange thus defining a handle for said container; said tab means being provided in said enlarged area; wherein said container defines four slightly inclined walls, said handle being provided on each of two opposite side walls of said container.

Claim 3

A container as defined in claim 1, wherein said weakened areas are reduced thicknesses in the material of said body and define a U-shaped outline in said enlarged area.

Claim 4

A container as defined in claim 1, wherein said container is formed of an injection-moulded plastic material.

Claim 5

A container adapted to securely engage a cover displaying a peripheral depending skirt, comprising: a body including side walls having an upper edge portion adapted to engage the peripheral depending skirt of a cover; said side walls including a peripheral flange consisting of a horizontal portion projecting outwardly from said side wall and of an outer vertical portion distanced from said side wall, said portions adapted to receive in close relationship therewithin a lower part of the skirt; and tab means having a horizontal portion integrally formed with said side wall and with said horizontal portion of said flange and a downwardly extending vertical portion integrally formed with said vertical portion of said flange; said horizontal and vertical portions of said tab means being connected to said horizontal and vertical portions of said flange through weakened areas to thereby render said tab means breakable when pressure is applied thereon thus providing visual indication of tampering, whether authorized or unauthorized, and adapted to allow removal of the cover from the container; wherein said downwardly extending vertical portion of said tab means includes an enlarged area relative to said vertical portion of said flange thus defining a handle for said container; said tab means being provided in said enlarged area; wherein said enlarged area includes an outwardly projecting lower portion displaying recessed areas along lower edges thereof; said recessed areas including an outer recessed area in vertical alignment with said outer vertical portion of said flange to thereby receive therein an upper portion of the outer vertical portion of a flange of a lower similarly constructed container in which said container is adapted to be nested.

Claim 6

A container adapted to securely engage a cover displaying a peripheral depending skirt, comprising: a body including side walls having an upper edge portion adapted to engage the peripheral depending skirt of a cover; said side walls including a peripheral flange consisting of a horizontal portion projecting outwardly from said side wall and of an outer vertical portion distanced from said side wall, said portions adapted to receive in close relationship therewithin a lower part of the skirt; and tab means having a horizontal portion integrally formed with said side wall and with said horizontal portion of said flange and a downwardly extending vertical portion integrally formed with said vertical portion of said flange; said horizontal and vertical portions of said tab means being connected to said horizontal and vertical portions of said flange through weakened areas to thereby render said tab means breakable when pressure is applied thereon thus providing visual indication of tampering, whether authorized or unauthorized, and adapted to allow removal of the cover from the container; wherein said downwardly extending vertical portion of said tab means includes an enlarged area relative to said vertical portion of said flange thus defining a handle for said container; said tab means being provided in said enlarged area; wherein said enlarged area includes an outwardly projecting lower portion displaying recessed areas along lower edges thereof; said recessed areas including an outer recessed area in vertical alignment with said outer vertical portion of said flange to thereby receive therein an upper portion of the outer vertical portion of a flange of a lower similarly constructed container in which said container is adapted to be nested.

Claim 7

A container as defined in claim 4, wherein said recessed areas include an inner recessed area in vertical alignment with the upper edge portion of the inclined side wall of the container to thereby receive therein the upper edge portion of the side wall of a similarly constructed container in which said container is adapted to be nested.

Claim 8

A container as defined in claim 5, wherein the upper edge portion of said container contains external circumferential bead means adapted to be securely engaged with internal circumferential bead means on the skirt of the cover.
