AMENDED CLAIMS

received by the International Bureau on 02 March 2012 (02.03.12)

1. A tamper evident container for holding a material, the container comprising:

a body having a bottom and a tubular element defining sides of the body and

extending upwardly from a periphery of the bottom, wherein an upper portion of the tubular element forms an aperture of the body;

a base having an annular portion including an externally directed annular protrusion which engages a recess in the apertui'e-forming portion of the tubular element of the body thereby effecting a permanent seal between the annular portion of the base and the top of the body, the base including a tamper evident removable central horizontal continuous panel extending inwardly from the annular portion of the base for enclosing material in the container; and

a lid adapted to removably engage the annular portion of the base, said lid comprising a transparent continuous central panel, for enclosing the material in the container when the lid is engaged with the base and allowing visual access to the material in the container once the tamper evident removable central horizontal continuous panel of the base has been removed,

wherein the base, lid and body are formed of thermoplastic material.

2. The container of claim 1 , wherein the base further comprises a handle disposed on the upper surface of the tamper evident horizontal continuous panel, said horizontal continuous panel of the base being connected to the annular portion by a thin tear tab membrane, whereby the horizontal continuous panel is configured to be removed from the base by applying force to the handle which causes the thin tear tab membrane to break.

3. The container of claim 2, wherein one or more of the body, the base, or the lid are fabricated from a Polyolefin such as PET or PEN.

4. The container of claim 1, wherein the aperture-forming portion of the tubular

element further comprises an internally directed annular protrusion configured to stop further insertion of the base when the base is inserted into the aperture of the body and contacts the internally directed annular protrusion.

5. The container of claim 1, wherein the externally directed annular protrusion

extends externally and upwardly and is therefore capable of flexing inwardly whilst being introduced into the aperture of the body of the container prior to coming to rest in the recess.

6. The container of claim 1 , wherein the resistance to permanent inward deformation of the externally directed protrusion exceeds the resistance to permanent outward deformation of the recess due to the radially externally directed protrusion being .fabricated from thicker thermoplastic material than that present in the recess.

7. The containerof claim 1 , wherein the radially externally directed protrusion

comprises 3 surfaces each of which, when the base is disposed in the aperture of the body, forms a seal with a corresponding surface of the aperture-forming portion of the tubular element of the body.

8. The container of claim 1, wherein the lid further comprises a first downwardly projecting portion for sealing engagement with an inner surface of a rim of the base and a second downwardly projecting portion for sealing engagement with an outer surface of the rim of the base.

9. The container of claim 1, wherein a base-engaging portion of the lid comprises 3 surfaces each of which, when the lid is affixed to the base, forms a seal with a corresponding surface of a rim of the base,

10. The container of claim 1, wherein the Hd comprises a periperhal annular bump on a top surface of the lid, the bump configured for stacking a second container on top of the container.

11. The container of claim 1, wherein when the lid is engaged with the base, the lid also contacts the body.

12. A method of storing and tinting paint material in the tamper evident container of claim 1, the method comprising the steps of:

placing untinted paint material into the body of the container;

attaching the annular portion of the base to the recess of the tubular element, thereby effecting a permanent seal between the annual portion of the base and the top of the body,

attaching the lid to the base for transportation and storage as desired,

removing the lid upon completion of transportation and storage,

removing the tamper evident horizontal continuous panel from the base,

inserting tint to the untinted paint within the container,

reattaching the lid to the annular portion of the base, thereby allowing visual access to the tinted paint within the container.
