摘要

A thermoformed article having two or more parts (125, 130) is provided. A first part is formed from a first thermoplastic material and a second part (130) is formed from a second thermoplastic material. The first and second materials are mutually incompatible. One of the parts (130) has one or more projections (131) and the other part (125) has one or more corresponding cavities (126a) into which the projections are formed. In which the mouth of the or each cavity is narrower than at least part of the or each projection such that the shape of the or each projection allows withdrawal from but resists reinsertion into the or each cavity.

1. A thermoformed article having two or more parts, a first part being formed from a first thermoplastic material and a second part being formed from a second thermoplastic material, the first and second materials being mutually incompatible, wherein the first part comprises an orifice and the second part comprises a panel formed to cover the orifice, such that in use, the panel can be removed to reveal the orifice and cannot be replaced, wherein the orifice forms a panel-receiving orifice extending through the first part, wherein the panel-receiving orifice is shaped and positioned to receive the panel, the panel fluidly blocking passage through the panel-receiving orifice, wherein the first part further comprises a top plate, the panel-receiving orifice extending through a thickness of the top plate, the top plate defining a perimeter of the panel-receiving orifice and a height of panel-receiving orifice side walls, and wherein one or more outer bottom surfaces of the panel are flush with a top surface of the top plate when the panel is received in the panel-receiving orifice.
