The paper container is disposed at the opening peripheral edge with a plastic ring in the way of integral-forming or assembling, and the plastic ring is assembled at the inner edge with a cover body in a combination manner like screw thread, etc., enabling the cover body to be combined to the inner edge surface in a quick-release manner for sealing the opening, so as to not only enhance the structural strength of the opening periphery of the paper container, but also to enhance the usage convenience thereof.

Description

Strengthening structure of the periphery of the opening of paper container (2)

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 the fourth figure is improved (hereinafter referred to as a conventional case). The structure disclosed in the conventional case comprises a cup body (91) and a cup sleeve (92). In the conventional case, the plastic film in-mold injection technology 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 feature disclosed in the above-mentioned conventional application is that the edge portion of the plastic material is formed at the edge of the edge of the paper container by the in-mold forming method, and the cover body is not added at the opening, so that there is still a molding and use. What can be improved, and there is a need to improve.

The main object of the present invention is to solve the above problems and to provide a "reinforcing structure (2) of the periphery of the opening of the paper container", which enables the reinforcing structure of the periphery of the opening of the paper container to be integrally formed or sleeved. At the same time, the cover can be set to enhance the function.

For the purpose of achieving the above-mentioned effects, the constitution of the "reinforced structure (2) of the periphery of the opening of the paper container" includes a paper container, a rubber ring, and a cover. The inner edge of the paper container has an accommodating space, and an opening is provided at the upper end, and the rubber ring can be formed by one-piece molding in the mold, or the outer-layer adhesive structure is disposed at the edge of the opening of the paper container. a peripheral portion of the inner edge of the upper end is formed with a first joint portion of an internal thread structure for coupling the cover body, and the cover system is formed with a second joint portion having an externally threaded structure on the outer circumferential surface of the outer ring, so that The quick release method is combined with the inner edge surface of the rubber ring to close the opening, which not only enhances the structural strength of the opening periphery of the paper container, but also improves the convenience of use.

The above-mentioned objects, structures and features of the present invention will be described in detail with reference to the preferred embodiments of the present invention. .

Referring to the first to third figures, the structure of the "reinforced structure (2) of the periphery of the opening of the paper container" comprises a paper container (10) and a glue bonded to the paper container (10). a ring (20), and a set of covers (30) disposed on an inner edge of the rubber ring (20), wherein: the paper container (10) is generally a cup-shaped or barrel-shaped or bowl-shaped container. The present invention uses a paper cup as an illustrative embodiment, mainly because the inner edge structure has a receiving space, and one end is provided with an opening (11), and the end edge of the opening (11) is linear.

The rubber ring (20) is a ring-shaped plastic ring body which can be integrally molded by in-mold injection molding to be formed at the edge of the opening (11) of the paper container (10), or after injection molding. Then, it is bonded to the end edge of the opening (11) of the paper container (10) by means of high-frequency bonding or the like. In the design of the structure, a first joint portion (21) is formed at a circumferential end of the inner edge of the rubber ring (20) for coupling the cover body (30), and the first joint portion (21) can be a thread. The quick-release structure can be easily combined with the cover (30). Secondly, the bottom edge of the bottom end is used to engage the edge of the opening (11) of the paper container (10) to form a loop (22).

The cover body (30) is a pair of circular pieces corresponding to the inner edge surface of the rubber ring (20), and the top edge surface is provided with a handle portion (31) which is held by the user's hand, and the outer ring circumferential surface is formed. There is a second joint portion (32) corresponding to the first joint portion (21), and the second joint portion (32) is also a threaded structure so that it can be combined with the first joint portion (21) of the rubber ring (20). A combination is provided to close the opening (11) of the paper container (10).

Thereby, the rubber ring (20) is molded on the paper container (10), and the structural design of the first joint portion (21) is provided, and the cover body (30) can be assembled to not only promote the paper material. The structural strength of the periphery of the opening (11) of the container (10) can also improve the convenience of use.

In summary, the present invention has excellent advancement and practicability in similar products, and at the same time, the technical materials of such structures are not frequently found in the literature and the literature, and the same structure is not found in the literature. The invention already has the invention patent requirements, and the application is filed according to law.
