Description

Technical Field

[0001] This utility model relates to a flexible tissue packaging body. Background Technology

[0002] Pull-out tissues are popular among consumers due to their convenience. They are usually packaged in cardboard boxes or flexible plastic. Flexible plastic packaging is also known as soft-pack packaging. It has a simple structure and is easy to use. However, for soft-pack packaging, there is a contradiction between ensuring the integrity of the packaging and making it easy to open. In the current technology, easy-tear lines or strips are usually used to form the tissue opening to achieve a balance between packaging integrity and easy opening.

[0003] To further improve the ease of opening while ensuring the integrity of the packaging, some improvements have been proposed in documents such as CN219383500U and CN211767602U. However, in practical use, these easy-tear strips are still difficult to open, especially when the packaging is full of contents, making it difficult to peel off the ends and pull the strip open. In improved solutions, such as CN220843741U, a design combining larger curved sections with straight sections on both sides is used to make it easier to open. However, due to the low strength of the plastic material itself, the ends are prone to cracking during the opening or extraction process. Statistics show that this cracking mainly occurs at both ends of the tissue dispenser, especially in the curved section area.

[0004] Therefore, a solution needs to be developed and implemented to address the aforementioned technical problems. Utility Model Content

[0005] Therefore, this utility model provides a flexible tissue packaging body to solve the above-mentioned technical problems.

[0006] A flexible tissue packaging body includes a body, the body including a top sheet, the top sheet including an easy-tear strip surrounded by perforated lines, the perforated lines including a pair of parallel spaced straight segments and a pair of first arc segments connecting the pair of straight segments, a second arc segment is also provided outside the first arc segment, and a deformation zone is included between the first arc segment and the second arc segment.

[0007] The virtual shear ratio of the perforated line is 2:1 to 20:1, and the virtual shear ratio of the first arc segment is greater than that of the second arc segment. The virtual shear ratio of the first arc segment is 10:1 to 20:1, and the virtual shear ratio of the second arc segment is 2:1 to 6:1.

[0008] The second arc segment intersects the first arc segment at the midpoint.

[0009] The tear strip is axially symmetrical and is symmetrically arranged along the first and second midlines. The midpoint is located on the second midline, and the deformation zone is divided into a first deformation zone and a second deformation zone along the second midline.

[0010] Both the first deformation region and the second deformation region are crescent-shaped.

[0011] If we define the point on the second arc segment that is furthest from the second median as the vertex, and the distance between the vertex and the second median as D1, and the distance between the straight line segment and the second median as D2, then D1 > D2.

[0012] Where D1-D2=2-5mm.

[0013] The first arc segment has a hole at its midpoint.

[0014] The second arc segment includes a third endpoint and a fourth endpoint, which are separate from the first arc segment.

[0015] The second arc segment includes a third arc segment extending to the first arc segment, and the bending direction of the third arc segment is opposite to that of the second arc segment. Beneficial effects: This utility model provides a flexible tissue packaging body, including a body, the body including a top sheet, the top sheet including an easy-tear strip surrounded by perforated lines, the perforated lines including a pair of parallel spaced straight segments and a pair of first arc segments connecting the pair of straight segments, the outer side of the first arc segments also including a second arc segment, and a deformation zone including the first arc segment and the second arc segment. On the one hand, the deformation zone increases the area of ​​friction of the tissue edge, thereby reducing the pulling effect on the edge of the extraction port during the extraction process. On the other hand, the second arc segment isolates the break or tear to prevent the tear from extending, thereby greatly reducing the occurrence of top sheet breakage. Attached Figure Description

Detailed Implementation

[0017] Please refer to Figures 1 to 2 The first embodiment of this utility model provides a flexible tissue packaging body for containing tissues and conveniently forming a pull-out opening, while maintaining the integrity of the pull-out opening so as to continuously remove the contained tissues from the pull-out opening.

[0018] The flexible tissue packaging body includes a body 10, which includes a receiving space formed by a top sheet 101, a bottom sheet, and several side sheets. The receiving space is used to hold tissues. Typically, the tissues are arranged in an alternating folding manner within the receiving space so that after each tissue is pulled out, at least a portion of the next tissue can be pulled out from the extraction port, thus facilitating user use. It is understood that the tissues can be folded in a V-shape or N-shape.

[0019] It is understood that the main body can be made from existing flexible packaging bag materials such as PP, PE, paper, and non-woven fabric. In other embodiments, materials such as cloth can also be used, and no specific limitation is made here.

[0020] The top sheet 101 includes an easy-tear strip 11 surrounded by perforated lines 12. It can be understood that the perforated lines 12 refer to a linear structure in which connecting sections and perforated sections are alternately arranged along an extension direction. The bonding strength of the material is greatly reduced at the perforated lines 12, so that the user can easily separate the material on both sides of the perforated lines 12. In this embodiment, the easy-tear strip 11 is separated from the top sheet 101 along the perforated lines 12.

[0021] The perforated line 12 includes a pair of parallel, spaced-apart straight segments 121 and a pair of first arc segments 122 connecting the pair of straight segments 121. A second arc segment 123 is also provided outside the first arc segment 122. A deformation zone is included between the first arc segment 122 and the second arc segment 123. It can be understood that the first arc segment 122 forms the end 110 of the easy-tear strip 11. When the user presses the end 110 to form a tear and peels off the easy-tear strip 11 from the end 110 to form a pull-out opening, it separates from the top piece 101 along the first arc segment 122. At the same time, since the second arc segment 123 is also a perforated line 12, a weak connection is formed at the second arc segment 123. Furthermore, a deformable deformation zone is formed inside the second arc segment 123. On the one hand, when the tissue is pulled out, the deformation zone increases the area of ​​friction between the tissue and the edge of the extraction port, thereby reducing the pulling effect on the edge of the extraction port during the extraction process. On the other hand, even if a crack occurs along the first arc segment 122 during the extraction process, the crack will only extend to the second arc segment 123 and will not extend further to other areas of the top sheet 101, causing the entire top sheet 101 to crack. This provides protection for the top sheet 101. Compared with the form of only setting the first arc segment 122, the occurrence of cracks with a length greater than 8mm on the top sheet 101 is reduced by 75% through the above setting.

[0022] It is understood that the tear strip 11 is configured to be axially symmetrical. If a first center line 111 and a second center line 112 are defined, the tear strip 11 is symmetrical along the first center line 111 in the length direction and symmetrical along the second center line 112 in the width direction.

[0023] It is understood that the perforated line 12 includes a virtual cutting ratio, which is 2:1 to 20:1. The virtual cutting ratio refers to the ratio of the length of the perforated section to the length of the connecting section in the perforated line 12.

[0024] Furthermore, the shear ratio of the first arc segment 122 should be greater than that of the second arc segment 123, so that the connection strength of the first arc segment 122 should be less than that of the second arc segment 123. This allows the user to break along the first arc segment 122 when pressing the end 110 to form a break, while maintaining the connection at the second arc segment 123. The connection strength refers to the strength at which the first arc segment 122 or the second arc segment 123 breaks when stretched on both sides.

[0025] Furthermore, the virtual shear ratio of the first arc segment 122 is 10:1 to 20:1, and the virtual shear ratio of the second arc segment 123 is 2:1 to 6:1.

[0026] Furthermore, the first arc segment 122 includes a first endpoint 1221, a second endpoint 1222 connecting a pair of straight segments 121, and a midpoint 1223 located between the first endpoint 1221 and the second endpoint 1222. The second arc segment 123 intersects the first arc segment 122 at the midpoint 1223, and the deformation area forms a first deformation area 1231 and a second deformation area 1232 along the second centerline 112. The first deformation area 1231 and the second deformation area 1232 protect the upper and lower edges of the end 110 and prevent the deformation area from being too large and easily falling off.

[0027] Furthermore, both the first deformation region 1231 and the second deformation region 1232 are crescent-shaped.

[0028] Furthermore, if we define the point on the second arc segment 123 that is furthest from the second centerline 112 as vertex 1233, the distance between vertex 1233 and the second centerline 112 as D1, and the distance between straight line segment 121 and the second centerline 112 as D2, then D1 > D2, making the second arc segment 123 convex outward, so that the deformation area can easily deform and increase the area of ​​friction at the edge of the tissue.

[0029] Furthermore, D1-D2=2-5mm.

[0030] Furthermore, the first arc segment 122 has a perforated section at the midpoint 1223, which makes it easier to form a hole along the first arc segment 122 when the end 110 is pressed.

[0031] Please refer to this as well. Figure 3 ,exist Figure 3 The image shows the tear strip end of the second embodiment, wherein the second arc segment 223 includes a third endpoint 2231 and a fourth endpoint 2232, wherein the third endpoint 2231 and the fourth endpoint 2232 are separated from the first arc segment 222 to prevent tearing from the third endpoint 2231 or the fourth endpoint 2232.

[0032] Furthermore, the distance between the third endpoint 2231 and the first arc segment 222 is 2-5mm, and similarly, the distance between the fourth endpoint 2232 and the first arc segment 222 is 2-5mm.

[0033] Please refer to this as well. Figure 4 ,exist Figure 4 The image shows the tear strip end of the third embodiment, wherein the second arc segment 323 includes a third arc segment 324 extending to the first arc segment 322, and the bending direction of the third arc segment 324 is opposite to that of the second arc segment 323, thereby making it less likely for tearing to occur in the area where the second arc segment 323 and the first arc segment 322 meet.
