Description

Lid positioning structure of paper cup

technical field

The present invention relates to the field of paper cups, in particular to the invention and creation of the structure in which the cup body and the cup cover of the paper cup are combined and fixed. the

Background technique

With the change of Chinese people's living habits, portable drinks such as coffee, fruit juice, pearl milk tea and various tea drinks are very popular at present. Based on the consideration of portability and cost, the current portable drinks are generally made of paper. Or plastic drinking cups to hold. Take-out coffee as an example, the cold and hot coffee cups for take-away are shown in the first figure, which consists of a cup body (100) and a cup cover (200), wherein the top of the vacuum-formed cup cover (200) has a round The opening (201) allows the straw to be inserted into the cup (100). After purchasing (take-away) hot coffee, consumers must open the cup cover (200) in order to add creamer or sugar into the coffee, but the cup cover (200) and the cup body (100) are combined by pressing , the user has to push the cup cover (200) upwards with fingers, so as to achieve the purpose of opening the cup cover (200). Therefore, when the user opens the cup cover (200), the coffee spills out and causes burns or splashes on the clothes, which is not only inconvenient, but also has safety concerns, and it is necessary to improve it. the

In view of this, the inventor has made in-depth discussions on the above-mentioned conventional creation problems, and actively sought solutions through years of experience in R&D and manufacturing in related industries. After long-term hard research and development, he finally successfully developed the present invention. The positioning structure of the lid of the paper cup is used to improve the problem of customary creation. the

Contents of the invention

The main purpose of the present invention is to solve the above problems and provide a positioning structure for the lid of a paper cup, which allows the paper cup body and lid to be opened in an easy and labor-saving manner, thereby improving the convenience of using the paper cup and security. the

In order to achieve the above-mentioned purpose, the lid positioning structure of the paper cup of the present invention is composed of a cup body and a lid. The cup body is made of paper material, the inner edge is hollow, the bottom has a cup bottom, and the top forms an open cup mouth for the cup cover to be set and combined. Mainly at the peripheral surface of the cup body located at the edge of the cup mouth, a cup rim can be provided by means of in-mold injection molding or post-processing solidification. The cup rim can be made of biodegradable plastic materials or other food-grade plastics formed, and a first helical part is formed on the outer side along its circumferential surface. Secondly, the cup cover is located on the inner wall corresponding to the rim of the cup, and a second helical part is formed along its peripheral surface, so that the cup cover is screwed with the first helical part by using the second helical part, which not only saves time for the combined operation , labor-saving, and can avoid the spillage of drinks caused by opening the lid, which greatly improves the convenience and safety of paper cups. the

To this end, the present invention provides a positioning structure for a cup lid of a paper cup, which includes a cup body, which is made of paper, and a cup lid can be set on the upper cup mouth, wherein: the cup body is located on the peripheral surface of the cup mouth There is a cup rim at the place, the cup rim is made of plastic material, and the outer side of the cup rim is formed with a first spiral part along its peripheral surface, and the cup cover is located on the inner wall surface corresponding to the cup rim, and also along its peripheral surface A second helical part is formed, so that the cup cover is screwed with the first helical part by the second helical part. the

Regarding the technology, means and effects adopted in the present invention, a preferred embodiment will be described in detail in conjunction with the drawings. It is believed that the above-mentioned purpose, structure and characteristics of the present invention should be able to gain a deep and specific understanding. . the

Detailed ways

Please refer to Figures 2 to 4, the positioning structure of the cup lid of the paper cup of the present invention is composed of a cup body (10) and a cup lid (20), wherein:

The cup body (10) is made of paper and is a general paper cup structure. The inner edge is hollow and can be used for liquids such as beverages. An open cup mouth (11) is formed on the top, and the edge of the cup mouth (11) is At the surface, a cup edge (12) can be provided by means of in-mold injection molding or post-processing solidification. The cup rim (12) The cup rim (12) is made of biodegradable plastic material or food-grade plastic, and a first spiral part (121) is formed on the outer side along the peripheral surface to combine with the cup cover (20). Based on the above, it is further explained that the paper material of the cup body (10) has a waterproof structure, that is, its outer edge is covered with a layer of adhesive film (not shown in the figure), so the cup edge (12) can be integrally formed or Post processing is fixed on this cup body (10). the

The general cover structure of the cup cover (20) can form a cover hole (21) for the insertion of a straw at an appropriate place on the top edge surface, and the bottom surface should be on the inner wall surface of the cup rim (12), and along its ring A second spiral part (22) is formed on the peripheral surface, so that the cup cover (20) is combined with the cup body (10) by screwing the second spiral part (22) and the first spiral part (121). the

Based on the above, it is further explained that the difference between the first helical part (121) and the second helical part (22) lies in the direction of the helix, which is generally called male teeth and female teeth. If the first helical part (121) When it is a male tooth, then the second spiral portion (22) is a female tooth. On the contrary, if the first helical part (121) is a female tooth, then the second helical part (22) is a male tooth. the

In addition, as shown in Figure 2 or 3, the first helical part (121) as a male tooth can be a complete circle of screw structure when it is formed, or it can be composed of several helical segments (122) (123) (124) Composition, the helical sections (122) (123) (124) are cut at equal angles to the helical direction of the first helical part (121). the

Accordingly, with the above-mentioned component composition, the cup body (10) of the paper cup and the cup lid (20) are screwed together by the first and second screw parts (121) (22), which not only saves time and effort in the combined operation, but also It can also avoid the spillage of beverages caused by the cup lid (20) being opened upwards, and greatly improves the convenience and safety of the paper feeding cup. the

In summary, the present invention has excellent progressive practicability among similar products, and at the same time, no similar structure has been found to exist in the domestic and foreign technical data and literature on this type of structure. Therefore, The present invention already meets the requirements of an invention patent, and an application is filed according to the law. the
