[0032] Next, in combination with the drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; for the convenience of description, hereinafter, the slots opened by the grooving part and the side slot opening part 3 after the cutting action will be called draw - openings.

[0033] Refer to Figure 1 , here is an example of the implementation manner of the main body:

[0034] A U - shaped zipper cutter for the incision of a tissue paper package includes a tool body part 1. At the lower end of the tool body part 1, a tooth - shaped part 2 for dot - punching is provided. In the middle of the lower end of the tool body part 1, a grooving part for opening an easy - pull opening is integrally formed. This grooving part is a special - shaped structure that protrudes outward.

[0035] Based on the above content, the tooth - shaped part 2 is used to punch dotted lines on the surface of the packaging bag, and the grooving part is used to open a slot on the surface of the packaging bag to form a draw - opening structure, so that the punched area on the surface of the packaging bag can be torn open through the draw - opening formed by the grooving part, which is convenient for use; the outward protrusion of the grooving part makes the grooving part have a larger opening. This opening makes it more convenient to take out the tissue paper in the package. When the remaining quantity of the tissue paper in the package is small, it will be difficult for the lower - layer tissue paper to be pulled out by the upper - layer tissue paper. At this time, it is necessary to reach into the packaging bag to take it. If a flat - mouth structure without protrusion is used, it will be inconvenient to take. Similarly, this structure with a protrusion to expand the opening also makes it more convenient to take the first piece of paper.

[0036] To prevent the user from accidentally breaking during the process of tearing the easy - pull opening due to operation errors, on the left and right sides of the lower end of the tool body part 1, side slot opening parts 3 for opening easy - pull openings are integrally formed. This structure enables continued use through the draw - openings on both sides when the draw - opening in the middle accidentally breaks.

[0037] For the convenience of installing the cutter body part 1, an extension part 4 is integrally formed at the upper end of the cutter body part 1. An extension hole 401 and an extension slot 402 are penetrated inside the extension part 4. The extension hole 401 can be used to connect an external cutting drive device, and the extension slot 402 can be used to install a limiting mechanism to prevent the cutter body part 1 from being inserted into the packaging bag too much.

[0038] Referring to Figure 2 , here is Example 1 of the implementation manner of the grooving part:

[0039] The grooving part includes a first notch part A1 with an arc-shaped structure. The first notch part A1 is opened on one side of the cutter body part 1. The grooving part with this structure makes the opening relatively flat, reduces the feeling of cutting or pricking the hand, and improves the using experience.

[0040] Furthermore, the first notch should be opened on the side in the drawing-out direction of the first piece of tissue paper, which can not only help the user determine the orientation of the first piece of tissue paper, but also facilitate the drawing-out of the tissue paper.

[0041] Referring to Figure 3 , here is Example 2 of the implementation manner of the grooving part:

[0042] The grooving part includes a second notch part A2 with an arc-shaped structure. The second notch part A2 is opened on both sides of the cutter body part 1. Compared with Example 1 of the implementation manner of the grooving part, in this embodiment, there are two sets of slits in the grooving part. When in use, two fingers can be directly inserted into the two sets of slits and pulled upward to tear it off, without considering the direction, and the opening is large and convenient to use.

[0043] Referring to Figure 4 , here is Example 3 of the implementation manner of the grooving part:

[0044] The grooving part includes a third notch part A3 with a special-shaped structure. The third notch part A3 is opened on both sides of the cutter body part 1. The third notch part A3 can be customized with different patterns by the manufacturer to achieve the differentiation of product packaging. The other beneficial effects of the third notch part A3 are the same as those of the second notch part A2.

[0045] Referring to Figure 5 , here is Example 4 of the implementation manner of the grooving part:

[0046] The grooving part includes a fourth notch part A4 with a special-shaped structure. The fourth notch part A4 is opened on one side of the cutter body part 1. The fourth notch part can also be customized with different patterns by the manufacturer. The other beneficial effects of the fourth notch part are the same as those of the first notch part A1.

[0047] Furthermore, the fourth notch part A4 should be opened on the side in the drawing-out direction of the first piece of tissue paper to facilitate the user to distinguish the opening orientation of the first piece of paper.

[0048] Referring to Figure 6, Here is the fifth example of the implementation of the slotted part:

[0049] The slotted part includes a fifth notch part A5 with an arc-shaped structure. A plurality of groups of the fifth notch part A5 are arranged on one side of the cutter body part 1. This structure enables the user to take the tissue paper from multiple positions, making the use more casual;

[0050] Furthermore, the fifth notch part A5 should be arranged on one side of the extraction direction of the first piece of tissue paper.

[0051] Finally supplemented:

[0052] The cutter body part should be a closed structure with an open lower end so that the incision is a closed structure;

[0053] The height difference between the toothed part and the slotted part and the side notch part should be less than 1 cm to avoid puncturing the tissue paper during the slotting process;

[0054] Comparing the above embodiments of unilateral special-shaped openings with the embodiments of bilateral special-shaped openings, the structural strength at the opening can be improved, so that it is not easy to tear when subjected to slight external force pulling.

[0055] Based on the above examples of each implementation method, when in use:

[0056] Select the slotted part with the required structure. After the selection is completed, fixedly connect the cutter body part 1 to an external cutting drive device through the extension part 4;

[0057] The toothed part 2 is used to mark an easy-to-pull dotted line area, and the slotted part and the side notch part 3 are used to form a pulling opening, so that the user can pull and tear along the dotted line area through the pulling opening.

[0058] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
