Description

Technical Field

[0001] This utility model relates to the field of cup containers, and in particular to an easy-tear structure for the outer cup of 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 cup is not easy to disassemble in existing technologies, this utility model provides an easy-tear structure for the outer cup of a combination cup that makes it easier to disassemble the outer cup.

[0004] This utility model provides an easy-tear outer cup structure for a combination cup, including a cup body paper tube. The cup body paper tube is formed by bonding the two ends of a fan-shaped piece together. The two ends of the fan-shaped piece are respectively provided with an inner overlapping edge and an outer overlapping edge. The end of the fan-shaped piece near the inner overlapping edge is provided with a V-shaped easy-tear line. The V-shaped easy-tear line includes a semi-circular full tangent line and a front upper half-cut diagonal line and a front lower half-cut diagonal line extending from the two ends of the semi-circular full tangent line to the upper and lower ends of the inner overlapping edge, respectively.

[0005] As a further improvement of this utility model, the V-shaped easy-tear line also includes a reverse upper half-cut diagonal line and a reverse lower half-cut diagonal line, which are respectively arranged parallel to the front upper half-cut diagonal line and the front lower half-cut diagonal line, and the reverse upper half-cut diagonal line and the reverse lower half-cut diagonal line are close to the inner overlapping edge.

[0006] As a further improvement of this utility model, the distance between the upper half of the front slant line and the upper half of the back slant line is 3.5-4.5mm.

[0007] As a further improvement of this utility model, the diameter of the semi-circular tangent is 15-20mm.

[0008] As a further improvement of this utility model, the distance between the upper end of the oblique line on the front half and the upper end of the inner overlapping edge is 15-25mm.

[0009] As a further improvement of this utility model, the distance between the lower end of the front half-cut diagonal line and the lower end of the inner overlapping edge is 15-25mm.

[0010] As a further improvement of this utility model, the semi-circular full tangent is a discontinuous full tangent.

[0011] As a further improvement of this utility model, the upper half-cut diagonal line and the lower half-cut diagonal line on the front are both discontinuous half-cut lines.

[0012] As a further improvement of this utility model, the easy-tear structure of the outer cup of the combination cup also includes a circular paper tray at the bottom of the cup. The inner side of the lower end of the paper tube of the cup body is provided with a first annular adhesive part. The first annular adhesive part is provided with a first water-based adhesive coating. The circular paper tray at the bottom of the cup 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. The first annular adhesive part can be bent inward and then attached to the second annular adhesive part.

[0013] 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.

[0014] The beneficial effects of this utility model are: the V-shaped easy-tear line on the cup body paper tube enables the outer cup to be quickly disassembled, thereby realizing the quick separation of the inner liner and outer cup of the combined cup, which facilitates garbage sorting and greatly improves the user experience.

Detailed Implementation

[0020] 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.

[0021] 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.

[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model discloses an easy-tear structure for the outer cup of a combination cup, including a cup body paper tube 1. The cup body paper tube 1 is formed by bonding the two ends of a fan-shaped piece together. The two ends of the fan-shaped piece are respectively provided with an inner overlapping edge 11 and an outer overlapping edge 12. A V-shaped easy-tear line is provided at one end of the fan-shaped piece near the inner overlapping edge 11. The V-shaped easy-tear line includes a semi-circular full tangent line 13 and a front upper half-cut diagonal line 14 and a front lower half-cut diagonal line 15 extending from the two ends of the semi-circular full tangent line 13 to the upper and lower ends of the inner overlapping edge 11, respectively.

[0024] When it is necessary to separate the inner liner 2 and the outer cup of the combination cup, you can first press the semi-circular full tangent line 13. The pressed area will be concave inward. Then pull it backward, which will tear the upper half tangent line 14 and the lower half tangent line 15 on the front. Since the V-shaped easy-tear line is connected to the inner overlapping edge 11 and the outer overlapping edge 12, the outer overlapping edge 12 can be separated from the inner overlapping edge 11 by pulling, thus tearing the entire cup body paper tube 1 apart. This can achieve quick separation of the cup body paper tube 1 and the inner liner 2, which facilitates garbage sorting and greatly improves the user experience.

[0025] The semi-circular full tangent 13 of this utility model is a discontinuous full tangent, that is, some points are connected together, and the rest are through cuts. This not only ensures that the semi-circular full tangent 13 will not open during normal use, but also makes it easy to press down when the outer cup is separated.

[0026] The upper half-cut diagonal line 14 and the lower half-cut diagonal line 15 on the front of this invention are both discontinuous half-cut lines, meaning that some points are not cut, while the remaining positions are cut through halfway. This not only ensures the overall stability of the outer cup during normal use, but also makes it easy to tear apart when the outer cup is separated, and also serves as a guide. Of course, the upper half-cut diagonal line 14 and the lower half-cut diagonal line 15 on the front can also be straight half-cut lines without discontinuities.

[0027] In this invention, the V-shaped easy-tear line further includes a reverse upper half-cut bevel line 16 and a reverse lower half-cut bevel line 17, which are respectively arranged parallel to the front upper half-cut bevel line 14 and the front lower half-cut bevel line 15. The reverse upper half-cut bevel line 16 and the reverse lower half-cut bevel line 17 are located near the inner overlapping edge 11. This further ensures the smooth tearing and guides the tearing of the V-shaped easy-tear line.

[0028] In this invention, the distance between the upper half-cut diagonal line 14 on the front and the upper half-cut diagonal line 16 on the back is 3.5-4.5mm. This ensures the stability of the outer cup and the continuity during tearing.

[0029] In this invention, the diameter of the semi-circular tangent 13 is 15-20mm, which facilitates hand-held pressing operation.

[0030] In this invention, the distance between the upper end of the upper half of the oblique cut line 14 on the front side and the upper end of the inner overlapping edge 11 is 15-25mm; the distance between the lower end of the lower half of the oblique cut line 15 on the front side and the lower end of the inner overlapping edge 11 is 15-25mm.

[0031] In this utility model, the easy-tear structure of the outer cup of the combination cup also includes a circular paper holder 3 at the bottom of the cup. The inner side of the lower end of the paper tube 1 of the cup body is provided with a first annular adhesive part. The first annular adhesive part is provided with a first water-based adhesive coating. The circular paper holder 3 at the bottom of the cup 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 31. The first annular adhesive part can be bent inward and then attached to the second annular adhesive part 31.

[0032] Because a first water-based adhesive coating is applied to the inner side of the lower end of the cup body paper tube 1, the round paper holder 3 at the bottom of the cup can use the original paper and can be bonded together without the need for PE composite paper for bonding. Thus, during waste recycling, since the entire outer cup body can be directly made from the original paper, the cup body paper tube 1 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 bonding part, the production cost is also relatively low.

[0033] In 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 32 that fits with the third annular adhesive part. The third annular adhesive part is provided with a second water-based adhesive coating. In this way, both the inner and outer sides of the annular side cardboard are bonded to the cup body paper tube 1, which can achieve a better connection effect and higher strength.

[0034] This invention features a V-shaped easy-tear line on the cup body paper tube 1, which enables the outer cup to be quickly disassembled, thereby facilitating the separation of the inner cup liner 2 from the outer cup and making it easier to sort garbage, thus greatly improving the user experience.

[0035] 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.
