Description

Technical Field

[0001] This utility model relates to the field of packaging auxiliary equipment technology, specifically to a paper hook for packaging bags. Background Technology

[0002] In daily shopping, small products are often hung on shelves using paper hooks. In the current technology, such hooks are usually manufactured using a single-row production method: their structure consists of two layers of surface material distributed on the top and bottom, and a reinforcing core layer bonded between the two layers. The cutting unit cuts the surface material on this single row to form a single-row hook product.

[0003] However, this single-row production process has obvious drawbacks: its production efficiency is low, and the output per unit time is completely limited by the speed of single-row cutting, making it difficult to meet the market's demand for large-scale, low-cost production, thus becoming a bottleneck restricting capacity improvement and cost control. Therefore, we propose a paper hook for packaging bags. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a paper hook for packaging bags to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A paper hook for packaging bags, characterized in that it comprises:

[0007] A face material is folded along its central fold line to form a first region and a second region that fit together. The first region and the second region are provided with multiple equal segments.

[0008] Pressure-sensitive adhesive layers are distributed in an array on equally divided segments, with adjacent pressure-sensitive adhesive layers separated by equally divided segments that are not coated with pressure-sensitive adhesive.

[0009] The reinforcing core layer is connected to the face material side. When the face material is folded, the reinforcing core layer adheres to the pressure-sensitive adhesive layer of the first and second areas to form an adhesive area, which is then cut to form multiple rows of hooks.

[0010] Preferably, the segments are parallel and of the same size, evenly distributed in the middle of the first and second regions, with edge portions on both sides.

[0011] Preferably, the length of the edge portion is the same as the length of the equal segments, and the width of the edge portion is at least half the width of the equal segments.

[0012] Preferably, the folded edge and the un-adhesive-sensitive segments are bonded together to form a covering area.

[0013] Preferably, the size of the reinforcing core layer is consistent with the size of the equally divided segments, and it is bonded to the corresponding pressure-sensitive adhesive layer.

[0014] Preferably, pre-indentation is provided between the fold line in the middle of the surface material and between adjacent equal segments.

[0015] This utility model provides a paper hook for packaging bags. It has the following beneficial effects:

[0016] 1. By setting multiple rows of parallel and equally sized segments on the surface material, and distributing pressure-sensitive adhesive layers and reinforcing core layers in an array on them, multiple hook blanks can be formed simultaneously in one processing step. After folding and cutting, multiple rows of finished hooks can be obtained at the same time, which completely changes the bottleneck of low production capacity of traditional single-row cutting and improves production efficiency several times.

[0017] 2. The equal segments are evenly distributed in the first and second regions, with edge portions on both sides. The pressure-sensitive adhesive layers are separated by uncoated equal segments, which not only ensures the independence of each hook unit and avoids cross-contamination of adhesives, but also maximizes the effective area of ​​the surface material, reduces waste of scrap materials, and lowers production costs.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] See attached document Figures 1-4A paper hook for packaging bags includes a face material 1 and a plurality of reinforcing core layers 2 attached to one side of the face material 1. The face material 1 is folded along its central fold line to form a first region 11 and a second region 12 that are attached to each other. A plurality of equally divided segments 13 are respectively provided in the first region 11 and the second region 12. The plurality of equally divided segments 13 are evenly distributed in the middle of the first region 11 and the second region 12 in parallel and of the same size, and have edge portions on both sides. The size of each reinforcing core layer 2 is consistent with the size of the equally divided segments 13.

[0025] It also includes pressure-sensitive adhesive layers 14, which are distributed in an array on equal segments 13. Adjacent pressure-sensitive adhesive layers 14 are separated by equal segments 13 without pressure-sensitive adhesive coating. Each reinforcing core layer 2 is bonded to its corresponding pressure-sensitive adhesive layer 14. When the face material 1 is folded, the back of the reinforcing core layer 2 is bonded to the pressure-sensitive adhesive layer 14 in another area to form an adhesive area 16. The hook 3 is then cut by a cutting unit, so that what was originally a single row available for cutting can now be multiple rows available for cutting, thus improving the production efficiency of the hook 3.

[0026] The folded edge and the equally divided segments 13 without pressure-sensitive adhesive layer 14 are bonded together to form a covering area 17.

[0027] The length of the edge portion is the same as the length of the equal segments 13, and the width of the edge portion is at least half the width of the equal segments 13.

[0028] Pre-indentation marks 15 are provided between the fold line in the middle of the surface material 1 and between the adjacent equal segments 13, so that the hook 3 can be folded after cutting.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0030] The above description is only used to illustrate the technical solutions of this utility model, and is not intended to limit it. Although the utility model has been described in detail with reference to the foregoing, those skilled in the art should understand that modifications can still be made to the foregoing technical solutions, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the various technical solutions of this utility model.
