Abstract
Description
An outer cup structure for a combination cup Technical Field
[0001] This utility model relates to the field of cup containers, and more particularly to an outer cup structure for a combination cup. Background Technology
[0002] Currently, cup noodle containers on the market generally fall into two categories: one with a single-layer cup structure and the other with a two-layer structure. The two-layer structure consists of an inner liner and an outer paper cup, also known as a combination cup. The inner liner, which needs to be waterproof and oil-proof, is mostly made of polypropylene, while the outer paper cup is made of paper. After consuming the cup noodles, the inner liner and outer paper cup of this combination cup need to be separated and disposed of according to the standards for waste sorting. However, in the current combination cups, the outer paper cup is glued to the inner liner, so it is not easy to separate them and may even require tools to disassemble, which is very inconvenient. Utility Model Content
[0003] To address the problem that the outer paper cup of a combination cup is not easy to disassemble in existing technologies, this invention provides an outer cup structure for a combination cup that can be quickly torn off.
[0004] This utility model provides an outer cup structure for a combination cup, including an outer cup body. The outer cup body includes a cup body paper tube and a circular paper support for the cup bottom located at the lower end of the cup body paper tube. The cup body paper tube is formed by fan-shaped pieces. The cup body paper tube has an overlapping portion formed by the end-to-end bonding of the fan-shaped pieces. One side of the overlapping portion has an easy-tear line arranged parallel to it. The easy-tear line has an easy-tear opening in the middle. The easy-tear line is an intermittent through-cut.
[0005] As a further improvement of this utility model, the easy-tear opening is a semi-circular through cut with both ends connected to the easy-tear line.
[0006] As a further improvement of this utility model, the shortest distance between the overlapping part and the tear line is 3-8mm.
[0007] As a further improvement of this utility model, the shortest distance between the upper edge of the cup body paper tube and the upper end of the easy-tear line is 5-15mm.
[0008] As a further improvement of this utility model, the through cut is in the shape of a wavy line.
[0009] As a further improvement of this utility model, the lower inner side of the cup body paper tube is provided with a first annular adhesive part, the first annular adhesive part is provided with a first water-based adhesive coating, the cup bottom circular paper holder includes a circular cardboard and an annular side cardboard provided around the circular cardboard, the inner side of the annular side cardboard is provided with a second annular adhesive part, and the first annular adhesive part can be bent inward and attached to the second annular adhesive part.
[0010] As a further improvement of this utility model, the first water-based adhesive coating of the first annular bonding portion is a strip-shaped adhesive coating structure with intervals.
[0011] As a further improvement of this utility model, the first water-based adhesive coating of the first annular bonding portion is an adhesive coating structure with strips arranged alternately.
[0012] As a further improvement of this utility model, the upper end of the first annular adhesive part is also provided with a third annular adhesive part, and the outer side of the annular side cardboard is provided with a fourth annular adhesive part that fits with the third annular adhesive part. The third annular adhesive part is provided with a second water-based adhesive coating.
[0013] As a further improvement of this utility model, the outer side of the cup body paper tube is provided with a water-based varnish coating.
[0014] The beneficial effects of this utility model are as follows: The easy-tear line is longitudinally set on the outer cup body, enabling rapid disassembly of the outer cup body. This facilitates quick separation of the inner liner and the outer cup body, making waste sorting easier and greatly improving the user experience. Furthermore, a first water-based adhesive coating is applied to the inner side of the lower end of the cup body paper tube, allowing the original paper to be used for the circular paper tray at the bottom of the cup, eliminating the need for PE composite paper for bonding. During waste recycling, since the entire outer cup body can be directly made from the original paper, no sorting is required, making it more environmentally friendly and eliminating additional waste disposal costs. Moreover, because only a ring of water-based adhesive is applied to the first annular bonding area, the production cost is relatively low. Attached Figure Description

[0022] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0023] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.
[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0025] As shown in Figures 1 to 6, this utility model discloses an outer cup structure for a combination cup, including an outer cup body 1. The outer cup body 1 includes a cup body paper tube 2 and a circular cup bottom paper holder 3 disposed at the lower end of the cup body paper tube 2. The cup body paper tube 2 is formed by fan-shaped pieces. The cup body paper tube 2 is longitudinally provided with an overlapping part 11 formed by the end-to-end bonding of the fan-shaped pieces. One side of the overlapping part 11 is provided with an easy-tear line 12 arranged parallel to it. The easy-tear line 12 is provided with an easy-tear opening 13 in the middle. The easy-tear line 12 is an intermittent through cut.
[0026] When in use, since the inner liner 5 of the combination cup is generally made of flexible materials such as polypropylene, you can directly press the easy-tear opening 13 of the easy-tear line 12 on the outer cup body 1 to make the easy-tear opening 13 of the outer body recessed inward. Then, pull the easy-tear line 12 backward. Since the easy-tear opening 13 is located in the middle of the easy-tear line 12, the easy-tear line 12 will split from the middle to both ends when pulled, so as to quickly disassemble the outer cup body 1. This allows for the quick separation of the inner liner 5 and the outer cup body 1, which facilitates garbage sorting and greatly improves the user experience.
[0027] The easy-tear line 12 of this utility model is provided on one side of the overlapping part 11, which can increase the strength of the pulling part when pulled, so that it can be torn open quickly and stably as a whole.
[0028] In this invention, the easy-tear opening 13 is a semi-circular through cut with both ends connected to the easy-tear line 12, which facilitates pressing with the fingertips and pulling to one side.
[0029] In this invention, the shortest distance between the overlapping part 11 and the easy-tear line 12 is 3-8mm, which ensures that the strength of the overlapping part 11 can be used to better achieve the tearing effect when tearing the easy-tear line 12.
[0030] In this invention, the shortest distance between the upper edge of the cup body paper tube 2 and the upper end of the easy-tear line 12 is 5-15mm, which can effectively ensure that the outer cup body 1 can be quickly and completely torn open.
[0031] In this invention, the through cut is wavy in shape, resulting in a better tearing effect.
[0032] In this utility model, the lower inner side of the cup body paper tube 2 is provided with a first annular adhesive part 21, the first annular adhesive part 21 is provided with a first water-based adhesive coating 4, the cup bottom circular paper holder 3 includes a circular cardboard 31 and an annular side cardboard 32 provided around the circular cardboard 31, the inner side of the annular side cardboard 32 is provided with a second annular adhesive part 321, and the first annular adhesive part 21 can be bent inward and attached to the second annular adhesive part 321.
[0033] In this invention, a first annular adhesive portion 21 is provided on the inner side of the lower end of the cup body paper tube 2, and the first annular adhesive portion 21 is provided with a first water-based adhesive coating 4. During processing, it is only necessary to place the cup bottom circular paper holder 3 inside the cup body paper tube 2, then heat the first water-based adhesive coating 4 on the first annular adhesive portion 21, and then bend the first annular adhesive portion 21 of the cup body paper tube 2 inward so that it is glued together with the second annular adhesive portion 321 of the cup bottom circular paper holder 3, thus completing the production of the outer cup body 1. Since the first water-based adhesive coating 4 is applied to the inner side of the lower end of the cup body paper tube 2, the cup bottom circular paper holder 3 can use the original paper and can also achieve bonding and assembly, eliminating the need to use PE composite paper for bonding. Thus, during waste recycling, since the entire outer cup body 1 can directly use the original paper, the cup body paper tube 2 does not need to be sorted, which is more environmentally friendly. Furthermore, since only a ring of water-based adhesive coating is applied to the first annular adhesive portion 21, the production cost is also relatively low.
[0034] In some embodiments, the first water-based adhesive coating 4 of the first annular bonding portion 21 is a strip-shaped adhesive coating structure with intervals, or the first water-based adhesive coating 4 of the first annular bonding portion 21 is a strip-shaped adhesive coating structure with staggered intervals. This not only achieves the bonding effect, but also further saves the amount of adhesive used, thereby further reducing production costs.
[0035] In some embodiments, the upper end of the first annular adhesive portion 21 is further provided with a third annular adhesive portion, and the outer side of the annular side cardboard 32 is provided with a fourth annular adhesive portion 322 that is attached to the third annular adhesive portion. The third annular adhesive portion is provided with a second water-based adhesive coating. In this way, both the inner and outer sides of the annular side cardboard 32 are bonded to the cup body paper tube 2, which can achieve a better connection effect and higher strength.
[0036] In this invention, the outer side of the cup body paper tube 2 is provided with a water-based varnish coating, which can play a role in waterproofing and oil resistance.
[0037] In this invention, both the first water-based adhesive coating 4 and the second water-based adhesive coating are acrylic adhesive coatings, which are more environmentally friendly.
[0038] This invention features a longitudinally designed easy-tear line 12 on the outer cup body 1, enabling rapid disassembly of the outer cup body 1 and quick separation of the inner cup liner 5 from the outer cup body 1. This facilitates waste sorting and significantly improves the user experience. Furthermore, a first water-based adhesive coating 4 is applied to the inner side of the lower end of the cup body paper tube 2, allowing the bottom circular paper tray 3 to use the original paper and achieve bonding without the need for PE composite paper. During waste recycling, since the entire outer cup body 1 can be directly made of the original paper, no sorting is required, making it more environmentally friendly and eliminating additional waste disposal costs. Moreover, since only a ring of water-based adhesive coating is applied to the first annular bonding part 21, the production cost is relatively low.
[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
