TH99249A - The injection molded method is openings on the sheet material for packaging of pourable food products and the resulting packaging and packaging materials. - Google Patents

Abstract

DC60 Injection molding method forms openings (3) on the packaging material (2) for product packaging. The food poured out by the packaging material (2) has at least the first (4) and second (5, 6) layers, and the opening (9) passes through the first (4) cavity and is sealed. It is closed by the cover (10) of the second layer (5, 6). By the way, it consists of a process of injecting the molten plastic material onto the first side (10a) of the cover (10) of the layer. The second (5, 6) and the molten plastic is fed along the wrong cover (10) to cover it on the first side (10a) and feed the molten plastic material through the section. It surrounds the ring shape of the cover (10) to form a pouring mouth (12) of the protruding opening (3). From the second side (10b) opposite to the first (10a) side of the hood (10), the molten plastic material covers the hood (10), and this, together with the hood (10), will It is constructed or established as a user-removable seal (15) of the pouring mouth (12) (Fig. 7), an injection molding method, forms an opening (3) on the packaging material (2). For packing products The food poured out by the packaging material (2) has at least the first (4) and the intended (5,6) layers, and the opening (9) passes through the first (4) and is The sealing is closed by the cover (010) of the intended layer (5,6). The method consists of a process of injecting a molten plastic material onto the first side (10a) of the filler housing (10). The second layer (5,6) and the molten plastic material protection follow the wrong cover (10) to cover it on the first side (10a) and feed the molten plastic material through the section. Around the ring shape of the cover (10) to form the pouring mouth (12) of the protruding opening (3). From the second side (10b) opposite to the first (10a) side of the hood (10) with the molten plastic material covering the hood (10), and this joins the hood (10). ) Will be constructed or defined as a user-removable seal (15) of the pouring mouth (12) (Fig. 7).
