Technical Field
The present invention relates to a laminated peel container and a method for manufacturing the same, and more particularly, to an easily manufactured laminated peel container.
Background
The existing lamination stripping container mainly comprises an outer layer and an inner layer which can be stripped from the outer layer, such as the invention patent No. I570029 of Taiwan China or the invention patent No. I602683 of Taiwan China, however, the structure of the former patent is complex and the manufacturing procedure is troublesome, so the existing lamination stripping container has high overall manufacturing cost and needs to be further improved.
In addition, taiwan patent No. 504451 (hereinafter referred to as "reference") discloses a method of manufacturing a pressure equalization opening container and a container including an outer container and an inner bag, in which an equalization opening is formed in the bottom surface of the outer container, wherein a coaxial primary mold is co-extruded from an open half of a blow mold, a proper amount of raw material is extruded, the raw material contacting the outer container and the seam portion is fused to form an inner bag to be clamped, and the inner bag is fixed and fused between the outer container wall portions in the axial direction to be pressed to form an equalization opening.
However, in these manufacturing methods according to the references, after the outer container and the inner bag are blow molded, the outer container is pressurized to extrude the equalization opening, and the manufacturing process is complicated, and the inner bag is clamped by the outer container during molding according to the references, so that after the equalization opening is pressurized to extrude, a part of the inner bag is still attached to one side surface of the equalization opening, as shown in fig. 7 of the references, thereby reducing the area of the equalization opening and reducing the effect of air entering the outer container through the equalization opening.
