Abstract: A package comprises an entirety of a tray (10) having an open side and a ring-shaped cover rim (20) which is located at the open side of the tray (10), at an outer circumferential rim (16) of the tray (10), and which is connected to the tray (10) through a relatively weak breaking portion (30). For the purpose of manufacturing the package, a mold (41) is provided. Also, a sheet (40) is provided and placed in the mold (41), wherein a movement of the sheet (40) is forced in two different directions. The cover rim (20) is formed with an inner ring (21) in which an inward bulge (28) is realized, along at least a portion of the circumference thereof, as an aids in establishing a clamping connection between the cover rim (20) and the tray (10) once the cover rim (20) has been broken away from the tray (10).

Abstract: A method of manufacturing a plastic product (1) having a bottom and an upright wall extending from a periphery of the bottom in an injection mold having a bottom-forming cavity and a wall-forming cavity. The cavities of the injection mold are filled with fluid plastic while pressure is being exerted in two stages with an interruption of the supply of fluid plastic therebetween.

Abstract: For the purpose of manufacturing a package, an entirety is provided by means of injection molding, the entirety including a plastic tray (10) having an open side and a ring-shaped plastic cover rim (20) which is located at the open side of the tray (10), at a circumferential rim of the tray (10), and which surrounds that circumferential rim. The cover rim (20) is connected to the tray (10) by means of a relatively thin plastic film, wherein the cover rim (20) and the tray (10) are detached from each other by forcing a limited mutual movement of the cover rim (20) and the tray (10). Furthermore, a piece of cover foil (40) is provided and connected to at least the cover rim (20). Preferably, the cover rim (20) and the tray (10) are adapted to be capable of getting into engagement with each other by means of a snap connection after they do no longer form an integral entirety with each other.
