Description

Technical Field

[0001] The utility model relates to the technical field of straws, and specifically relates to a combined straw. Background Art

[0002] At present, paper straws have a single-layer structure and a multi-layer paper spiral winding structure. The single-layer paper straw can withstand high-temperature soaking without collapsing or spreading, but the hardness of the plug is not enough, and there is a situation where it cannot be pierced when piercing the sealing film. For the current integrated spiral-wound paper straw, although the hardness of the plug is sufficient, since the whole is formed by spirally winding and pasting multiple sections of paper with glue, and the straw has a certain length, the amount of glue used will be relatively large. And a large amount of glue in the paper straw will pose safety hazards, and the straw is prone to looseness. Content of the Utility Model

[0003] The utility model provides a combined straw, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A combined straw includes a straw body and a straw plug. The straw body has a single-layer structure, and the straw plug has a multi-layer paper spiral winding structure. The diameter of the straw body is larger than that of the straw plug. The straw plug is combined and connected with the straw body, and a connection part is formed through heat-sealing lap joint. The overlapping diameter depth at the lap joint of the connection part is 5 - 20 mm.

[0006] A preferred technical solution: The connection part is a spiral embossed structure.

[0007] A preferred technical solution: The straw body and the straw plug are made of coated paper.

[0008] A preferred technical solution: The coated paper is heat-sealed and connected through a coating to form the straw body or the straw plug.

[0009] A preferred technical solution: The straw plug is adhesively made by spirally winding 2 - 4 layers of paper.

[0010] A preferred technical solution: The straw body and the straw plug are hollow structures.

[0011] A preferred technical solution: One end of the straw plug is a pointed head formed by an inclined slope.

[0012] A preferred technical solution: The angle of the pointed head is 30° - 60°.

[0013] A preferred technical solution: The outer diameter of the straw plug is at most equal to the inner diameter of the straw body.

[0014] A preferred technical solution: The total length of the combined straw is 150 mm - 300 mm.

[0015] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0016] The straw in the present utility model is a combined straw. The whole or part of the straw adopts glue-free coated paper, reducing the amount of glue used and improving the safety during the use of the straw. Moreover, the straw plug is specifically set as a multi-layer structure to ensure the hardness of the straw plug and facilitate piercing the sealing film. To a certain extent, the overall manufacturing cost of the straw can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment 1

[0024] As Figures 1 - 3 shown, this embodiment provides a combined straw, including a straw body 1 and a straw plug 2. The straw body 1 is a single-layer structure, and the straw plug 2 is a multi-layer paper spiral winding structure. The diameter of the straw body 1 is larger than that of the straw plug 2. The straw plug 2 is combined and connected with the straw body 1, and a connecting part 3 is formed through heat-sealing overlap. The overlapping depth of the connecting part 3 is 5 - 20 mm. The depth is the depth of the straw plug 2 inserted into the straw body 1, which can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 15 mm, 20 mm, or any other value within the range of 5 - 20 mm, such as 5.5 mm, 6.5 mm, 7.6 mm, 11.5 mm, 16.7 mm, etc.

[0025] Furthermore, the straw body 1 and the straw plug 2 are made of coated paper.

[0026] Furthermore, the coated paper is heat-sealed and connected through a coating to form the straw body 1 or the straw plug 2.

[0027] Furthermore, the straw plug 2 is made by spiral winding and gluing 2 - 4 layers of paper, and preferably 3 layers or 4 layers of paper.

[0028] Furthermore, the straw body 1 and the straw plug 2 are hollow structures.

[0029] Furthermore, one end of the straw plug 2 is a pointed head 21 formed by an inclined slope.

[0030] Furthermore, the angle of the pointed head 21 is 30° - 60°, and the preferred angle is 45°.

[0031] Furthermore, the outer diameter of the straw plug 2 is at most equal to the inner diameter of the straw body 1.

[0032] Furthermore, the total length of the combined straw is 150 mm - 300 mm, and the preferred total lengths are 190 mm, 210 mm, 230 mm, 240 mm, or any point value within the range.

[0033] Example 2

[0034] This embodiment provides a combined straw. The difference between this embodiment and Embodiment 1 is that the connecting portion 3 is a spiral embossed structure, that is, a spiral embossed structure is formed when heat-sealing and connecting the overlapping portion of the straw plug 2 and the straw body 1, which improves the overlapping effect, has strong connection stability, and is not easy to fall off.

[0035] The combined straw in the present utility model uses a non-glue paper material (coated paper) and is formed by heat-sealing with a coating; it abandons the traditional method of forming a straw by pasting with glue, avoiding the unsafe factors caused by glue when sucking hot drinks with the straw.

[0036] The straw plug 2 is a multi-layer paper spiral winding structure, which can improve the hardness of the plug and efficiently pierce the sealing film. The straw plug 2 is formed by heat-sealing and overlapping with the straw body 1, which improves the connectivity between the straw plug 2 and the straw body 1 and is convenient for better sucking the beverage when using the straw.

[0037] Example 3

[0038] This embodiment provides a combined straw. The difference between this embodiment and Embodiment 1 is that the straw plug is made of white kraft paper and yellow kraft paper bonded with glue to form a multi-layer paper spiral winding structure, effectively ensuring the hardness of the straw plug.

[0039] The above are only preferred embodiments of the present utility model, so the scope of implementation of the present utility model cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present utility model patent and the content of the specification should still fall within the scope covered by the present utility model.
