| 摘要 |
The present invention relates to a packaging device (1) for bulk goods (3), particularly for use for foods such as coffee beans, cocoa beans, rice, spices and seeds in general, comprising at least one vacuum bag (2) defining an open side (2d) for insertion of the bulk goods (3) therein and hermetically sealable at the open side (2d) subsequent to evacuation of the air contained therein. The particular feature of the invention consists in the fact that the packaging device (1) comprises at least two sheet-like elements (8, 9, 12, 13, 208, 209, 212, 213) made of a material substantially more rigid than the material with which the vacuum bag (2) is made, fastened to the external surfaces (6a and 6b) of the vacuum bag (2) and which can be positioned transversely with respect to one another following filling of this vacuum bag (2) with the bulk goods (3) and its consequent deformation in a manner such that the two sheet-like element (8, 9, 12, 13, 208, 209, 212, 213) are maintained transverse to one another in the presence of a vacuum pressure produced inside this vacuum bag (2). |
