This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0023] In the description of the utility model, if there is a description of quantity, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of first or second, it is only used to distinguish the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0024] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0025] like Figures 1 to 6As shown, the utility model discloses an outer cup structure of a combination cup, comprising an outer cup body 1, wherein the outer cup body 1 comprises a cup body paper tube 2 and a cup bottom circular paper holder 3 arranged at the lower end of the cup body paper tube 2, wherein the cup body paper tube 2 is surrounded by fan-shaped pieces, and the cup body paper tube 2 is longitudinally provided with an overlap portion 11 formed by bonding the fan-shaped pieces end to end, and one side of the overlap portion 11 is provided with an easy tear line 12 arranged parallel to the overlap portion 11, and the middle part of the easy tear line 12 is provided with an easy tear opening 13, and the easy tear line 12 is an intermittently arranged through cut.

[0026] During use, since the inner liner 5 of the combination cup is generally made of flexible materials such as polypropylene, the tear opening 13 of the tear line 12 on the outer cup body 1 can be directly pressed to make the tear opening 13 of the outer body concave inward. At this time, the tear line 12 is pulled backward. Since the tear opening 13 is located in the middle of the tear line 12, the tear line 12 can be split from the middle to both ends by pulling force when pulling, thereby realizing the rapid disassembly of the outer cup body 1, thereby realizing the rapid separation of the inner liner 5 of the combination cup from the outer cup body 1, thereby facilitating garbage classification and greatly improving the user experience.

[0027] The easy-tear line 12 of the utility model is arranged on one side of the overlapping portion 11, so that the strength of the pulling portion can be increased when pulling, so that it can be torn apart quickly and stably as a whole.

[0028] In the present invention, the easy-tear opening 13 is a semicircular through cut and both ends are respectively connected to the easy-tear line 12, so as to facilitate pressing by the fingertips and pulling to one side.

[0029] In the present invention, the shortest distance between the overlapping portion 11 and the easy tear line 12 is 3-8 mm, so as to ensure that when the easy tear line 12 is torn, the strength of the overlapping portion 11 can be used to achieve a better tearing effect.

[0030] In the present 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 5-15 mm, which can effectively ensure that the outer cup body 1 can be quickly and integrally torn open.

[0031] In the utility model, the through cut is in a wave shape, which has a better tearing effect.

[0032] In the utility model, 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 glue coating 4. The circular paper tray 3 at the bottom of the cup includes a circular paperboard 31 and an annular side surrounding paperboard 32 arranged on the outer periphery of the circular paperboard 31, and a second annular adhesive portion 321 is provided on the inner side of the annular side surrounding paperboard 32. The first annular adhesive portion 21 can be bent inwardly and fit with the second annular adhesive portion 321.

[0033] In the utility model, a first annular adhesive portion 21 is arranged 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 glue coating 4. During processing, it is only necessary to place the cup bottom circular paper holder 3 in the cup body paper tube 2, and then heat the first water-based glue 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 to make it stick together with the second annular adhesive portion 321 of the cup bottom circular paper holder 3, and the production of the outer layer cup body 1 is completed. Since the first water-based glue coating 4 is coated on the inner side of the lower end of the cup body paper tube 2, the cup bottom circular paper holder 3 can use base paper, and can also achieve bonding combination, and there is no need to use PE composite paper to achieve bonding. In this way, when garbage is recycled, since the entire outer layer cup body 1 can directly use base paper, the cup body paper tube 2 does not need to be sorted and processed, which is more environmentally friendly, and since only a circle of water-based glue coating is coated on the first annular adhesive portion 21, the production cost is also relatively low.

[0034] In some embodiments, the first water-based glue coating 4 of the first annular adhesive portion 21 is a strip-shaped glue coating structure that is arranged at intervals, or the first water-based glue coating 4 of the first annular adhesive portion 21 is a strip-shaped glue coating structure that is staggered. This not only can play a bonding role, but also can further save the amount of glue used, thereby further reducing production costs.

[0035] In some embodiments, a third annular adhesive portion is further provided at the upper end of the first annular adhesive portion 21, a fourth annular adhesive portion 322 is provided on the outer side of the annular side surrounding cardboard 32 and is bonded to the third annular adhesive portion, and the third annular adhesive portion is provided with a second water-based glue coating, so that both the inner and outer sides of the annular side surrounding cardboard 32 are bonded to the cup body paper tube 2, which can achieve a better connection effect and higher strength.

[0036] In the utility model, a water-based varnish coating is provided on the outer side of the cup body paper tube 2, and the water-based varnish coating can play a role of being waterproof and oil-proof.

[0037] In the present invention, the first water-based glue coating 4 and the second water-based glue coating are both acrylic glue coatings, which are more environmentally friendly.

[0038] The utility model arranges an easy-tear line 12 longitudinally on the outer cup body 1, which can realize the rapid disassembly of the outer cup body 1, so as to realize the rapid separation of the combined cup liner 5 and the outer cup body 1, thereby facilitating the garbage classification and greatly improving the user experience. In addition, a first water-based glue coating 4 is coated on the inner side of the lower end of the cup body paper tube 2, so that the circular paper tray 3 at the bottom of the cup can use the base paper and can also be bonded and combined, and there is no need to use PE composite paper to achieve the bonding effect. In this way, when recycling garbage, since the entire outer cup body 1 can directly use the base paper, there is no need for classification and processing, which is more environmentally friendly and does not require additional garbage disposal costs. In addition, since only a circle of water-based glue coating is coated on the first annular bonding portion 21, the production cost is also relatively low.

[0039] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
