Abstract: A plastics molding process is provided in which a first (2) and a second plastic part (3) are molded such that a contact surface is formed between the two parts. The first part (2) is molded firstly and, while at least the contact surface is still in a liquid or plastic state, an attachment promoting powder (16) that is compatible with, and has the characteristic of attaching to, the plastic of the first part (2), is applied to it. Thereafter, the second part (3) is molded so as to contact the first part at the contact surfaces such that as it solidifies, it attaches to the attachment promoting powder (16) and thereby to the first part (2). The second part (3) may be a plastic foam filling for a hollow first part (2). The attachment promoting powder (16) may be a suitable grade of diatomaceous earth or a natural or synthetic equivalent.

Abstract: A delivery container for temperature sensitive goods is provided having sidewalls, a rear wall, top and bottom walls all of a heat insulated construction, an upright access opening opposite the rear wall and a door assembly for selectively closing the access opening. Multiple generally upright cavities are associated with the sidewalls and rear wall. A cooling gas distribution arrangement includes a refrigerant receiving recess (12) provided in a refrigerant support tray having surfaces (15) inclined downwardly towards an upper region of the sidewalls and rear wall for distributing cooling gases generated by refrigerant located in the refrigerant receiving recess (12) to openings communicating with the multiple upright cavities, in use. The door assembly preferably includes an uppermost panel (35) that opens separately from the balance (36, 37, 38) of the door to provide access to the refrigerant receiving recess (12) for installing or removing refrigerant whilst the rest of the door assembly remains closed.
