Description

Strengthening structure of the periphery of the opening of the paper container (1)

The present invention is in the field of paper containers, and in particular refers to an invention for enhancing the structural strength of the opening of a paper container.

Press, paper containers, such as dishes, paper cups or lunch boxes, etc., are widely used because of their ease of use, which can reduce the quality of plastic materials that cannot be decomposed. With the progress of the times and the changes in the living habits of Chinese people, there are currently portable drinks such as coffee, juice, pearl milk tea and various tea drinks. Due to the convenience of carrying and cost considerations, the current portable drinks are generally They are all dressed in paper beverage cups. For paper cups or beverage cups, because of the paper structure, the structural strength of the paper itself is poor. Therefore, the original creation of the creator of this case is attached to the paper container cup. A rim portion of a plastic material is formed at the edge of the ring, and the structure of the paper cup container shown in FIG. 11 is improved (hereinafter referred to as a conventional case). The structure disclosed in the conventional case includes a cup body (91) and a cup sleeve ( 92) In the conventional case, a plastic in-mold injection technique is used on the top edge of the cup body (91) to form a debondable plastic material glue layer (93) to enhance the structural strength of the cup body (91).

The technical features disclosed in the above-mentioned conventional application are only to form the rim portion of the plastic material at the edge of the edge of the paper container by the in-mold forming method, and in fact, it can also be used at the upper end of the paper container by the sleeve combination method. At the edge, a strengthened rim structure is formed and further developed.

The main object of the present invention is to solve the above problems and to provide a "reinforcing structure (1) for the periphery of the opening of a paper container, which is a reinforcing structure of the periphery of the opening of the paper container, which can be integrated in a sleeve manner. At the same time, it makes the molding of various additional functions easier.

For the purpose of achieving the above-mentioned effects, the "reinforced structure (1) of the periphery of the opening of the paper container" comprises a paper container and a rubber ring, the inner edge of the paper container has a receiving space, and the periphery of one end opening is provided. There is a folding edge, and the rubber ring is a pair of plastic material ring bodies which should be folded in shape, and a ring groove is formed on the rim surface of the folded edge, so that the rubber ring can be sleeved and bonded to the outer edge of the folded edge. However, the structural strength of the opening periphery of the paper container can be improved by using the combination of the sets. In addition, in the design of the auxiliary function of the paper container, at least one positioning portion may be formed at the same time on the outer periphery of the outer edge of the rubber ring for the outer side of the brewing of tea bags or coffee bags. Extension positioning. It is to be noted that the positioning portion may have an inverted V-shaped pore structure, and when the extending portion of the infusion material is a wire rope, the extending portion may be engaged in the positioning portion to fix the infusion product. Or a plurality of positioning portions are formed on the circumferential surface of the rim portion, and each of the positioning portions has a groove shape, and can be bundled at a tip end thereof to form a pointed tail when the brewing material is extended. When there are a plurality of cross-legged structures, after the extensions are spanned, the extensions are bundled and fixed by the edge to ensure that the infusion is firmly positioned at the opening of the paper container. Furthermore, the upper end of the paper container can be further assembled with a cover body to close the opening, and the cover body is coupled to the circumferential surface of the rubber ring and the cover body to form corresponding spiral portions or engaging portions, respectively. The cover body can be easily combined with the rubber ring of the paper container, thereby improving the structural strength of the paper container and improving the convenience of the function.
