Package, Method For Manufacturing A Package, And Mold For Application For The Purpose Of Such Method

摘要

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).

1. A method for manufacturing a package comprising an entirety of a tray having an open side and a ring-shaped cover rim which is located at the open side of the tray, at an outer circumferential rim of the tray, and which is connected to the tray through a relatively weak breaking portion, wherein a mold is provided, wherein a sheet is provided and is placed in the mold, and wherein a movement of the sheet is forced in two different directions for forming the sheet as the package having the tray and the cover rim, wherein the sheet is clamped along a ring-shaped portion, and wherein a portion of the sheet inward of the ring-shaped portion and a portion of the sheet outward of the ring-shaped portion are moved in the two different directions; and wherein the forming movements of the sheet in the mold as desired are realized by applying pressure differences over the sheet in two different directions in the mold.
