A tamper evident container (10) where the base (12) has an inverted U-shaped section (25) connected to the base sidewall (21), and an annular flange (16a) extending from the base inverted U-shaped section (25) such that the base annular flange (16a) extends in a plane generally parallel to the base

A tamper evident container (10) where the base (12) has an inverted U-shaped section (25) connected to the base sidewall (21), and an annular flange (16a) extending from the base inverted U-shaped section (25) such that the base annular flange (16a) extends in a plane generally parallel to the base bottom wall (23). The lid also features an inverted U-shaped section (45) connected to the lid top surface (43), and an annular flange (16b) extends from the lid inverted U-shaped section (45) such that the lid annular flange (16b) extends in a plane generally parallel to the lid top surface (43). The base and lid inverted U-shaped sections (25, 45) are sized such that, when mounted to one another, the base and lid annular flanges (16a, 16b) abut one another and may be bonded together to thereafter form a tearable strip.

1. A tamper evident container, comprising: a base and a lid mountable thereon;the base having a bottom wall, a base sidewall extending transverse to the base bottom wall, an inverted U-shaped section connected to the base sidewall, and an annular flange extending from the base inverted U-shaped section such that the base annular flange extends in a plane generally parallel to the base bottom wall; andthe lid having a surface cap, an inverted U-shaped section connected to the lid surface cap, and an annular flange extending from the lid inverted U-shaped section such that the lid annular flange extends in a plane generally parallel to the lid surface cap;wherein the base and lid inverted U-shaped sections are sized such that, when mounted to one another, the base and lid annular flanges abut one another;wherein the lid and base inverted U-sections each have projections that together provide a deformable detent mechanism for releasably locking the lid to the base;wherein the cross-sectional thickness of a first junction between the base annular flange and the base inverted U-section is narrower than the cross-sectional thickness of a wall that provides the base inverted U-section; andwherein the cross-sectional thickness of a second junction between the lid annular flange and the lid inverted U-section is narrower than the cross-sectional thickness of a wall that provides the lid inverted U-section;wherein the first junction between the base annular flange and the base inverted U-section defines a corner and the second junction between the lid annular flange and the lid inverted U-section is located radially outward of the first junction so as to enable the base and lid annular flanges to be torn away from the base and lid inverted U-shaped sections along different parting lines. 2. A container according to claim 1, wherein: the base inverted U-shaped section comprises a first sidewall portion connected to the base sidewall, a bight portion, and a second sidewall portion connected to the base annular flange, the base projection depending from the second sidewall portion;the lid inverted U-shaped section comprises a first sidewall portion connected to the lid surface cap, a bight portion, and a second sidewall portion connected to the lid annular flange, the lid projection depending from the second sidewall portion; andthe base projection abuts against the lid second sidewall portion causing the base first sidewall portion to abut and seal against the lid first sidewall portion. 3. A container according to claim 1, wherein the base and lid annular flanges are bonded to one another. 4. A container according to claim 2, wherein: the base second sidewall portion is substantially linear and the base projection extends outwardly therefrom;the lid second sidewall portion is substantially linear and the lid projection extends outwardly therefrom; andthe lid projection is situated underneath the base projection when the lid is mounted on the base. 5. A container according to claim 1, including a pull tab connected to at least one of the base and lid annular flanges. 6. A container according to claim 1, wherein the base and the lid are formed from polypropylene.
