Description

Technical Field

[0001] This utility model relates to the field of heat shrink film, specifically to a heat shrink film chain packaging for batteries. Background Technology

[0002] Currently, heat shrink film packaging is widely used in battery pack packaging due to its low cost and good protection. Battery packs are generally packaged in boxes, with each box then hung on a shelf. In convenience stores and other sales scenarios, it's ideal for batteries to be hung on the side of the shelf in a chain-like manner, which takes up less space and makes it easier for consumers to pick them up and buy them. However, there is currently a lack of suitable heat shrink film packaging. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a heat shrink film chain packaging for batteries.

[0004] To solve the above problems, this utility model provides a heat-shrink film chain packaging for batteries. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows:

[0005] A battery heat-shrink film chain packaging includes: an adhesive section, wherein two heat-shrink films are bonded together; a non-adhesive section, wherein two heat-shrink films are not bonded together, and a plurality of adhesive sections and a plurality of non-adhesive sections are arranged alternately in a straight line; an easy-tear line located in the adhesive section, wherein the two ends of the easy-tear line are connected to the two sides of the heat-shrink film; and a through hole located in the adhesive section, wherein the through hole does not contact the easy-tear line; wherein the non-adhesive sections of the two heat-shrink films can accommodate a battery, and the non-adhesive sections still form side openings on both sides of the heat-shrink film after being subjected to heat shrinkage.

[0006] As a further improvement of this utility model, each non-adhesive segment can accommodate several parallel-arranged batteries, the axial direction of the batteries is parallel to the length direction of the heat-shrinkable film, and the opening area of ​​the side opening is smaller than the side-view projection area of ​​a single battery.

[0007] As a further improvement of this utility model, when the heat shrink film is not heated and shrunk, the two heat shrink films are long strip films of the same size and thickness.

[0008] As a further improvement of this utility model, when the heat-shrinkable film is not heated and shrunk, the outline of the adhesive section is rectangular, and the area occupied by the non-adhesive section in the heat-shrinkable film is greater than the area occupied by the adhesive section in the heat-shrinkable film.

[0009] As a further improvement of this utility model, when the heat-shrinkable film is not shrunk by heat, the length of the non-adhesive segment is greater than the sum of the axial length of a single battery and the diameter of a single battery.

[0010] As a further improvement of this utility model, the tear line extends laterally along the heat shrink film, and the tear line divides the adhesive section into two equal parts.

[0011] As a further improvement of this utility model, the same adhesive section has several through holes, which are symmetrically distributed on both sides of the easy-tear line.

[0012] As a further improvement of this utility model, the number of through holes in the same adhesive segment is four, and the vertical distance from each through hole to the connected easy-tear line is the same.

[0013] As a further improvement of this utility model, the heat shrink film is made of POF, PET, OPS or PVDC.

[0014] As a further improvement of this utility model, the thickness of the heat shrink film is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0015] The beneficial technical effects of using the heat-shrink film chain packaging of the battery according to this application are:

[0016] By arranging adhesive and non-adhesive sections alternately in a straight line, a chain-like packaging structure for batteries is achieved, meeting the needs of convenience stores and other scenarios where batteries can be hung on shelves in a similar chain-like manner. Compared to traditional box packaging, it occupies less space and is more likely to stimulate consumers' desire to pick it up at any time, filling the current gap in heat-shrink film packaging for this type of hanging requirement.

[0017] The easy-tear lines on the adhesive section are connected to both sides of the heat-shrink film, allowing consumers to easily tear off single or multiple non-adhesive sections containing batteries from the chain packaging as needed. This convenient operation requires no additional tools. Through-holes facilitate hanging on hooks.

[0018] Even after the non-adhesive section shrinks due to heat, side openings can still be formed on both sides of the heat-shrink film. These side openings are not for the battery to detach, but rather to eliminate the need for heat-shrink film on both sides of the battery, allowing a narrower heat-shrink film to fulfill the packaging function. This achieves both secure wrapping and protection of the internal battery through heat shrinking and retains the side opening structure. On the one hand, the narrower heat-shrink film helps control packaging costs. On the other hand, the side openings allow consumers to quickly tear open the packaging film.

[0027] The present invention will be further described in detail below with reference to specific embodiments:

[0028] To achieve the purpose of this utility model, a heat-shrink film chain packaging for batteries includes: an adhesive section 6, where two heat-shrink films are bonded together; a non-adhesive section 7, where two heat-shrink films are not bonded together; and several adhesive sections 6 and several non-adhesive sections 7 arranged alternately in a straight line; an easy-tear line 5 located on the adhesive section 6, with both ends connected to the two sides of the heat-shrink film; and a through hole 4 located on the adhesive section 6, which does not contact the easy-tear line 5. The non-adhesive sections 7 of the two heat-shrink films can accommodate a battery 1. Figures 3 to 5 As shown, the non-adhesive section 7 still forms side openings 8 on both sides of the heat-shrink film after undergoing heat shrinkage.

[0029] When the two heat shrink films are not bonded together, they are two independent single-layer films 2. When the two heat shrink films are bonded together, they are double-layer films 3.

[0030] Figure 1 The step-by-step processing of heat shrink film is shown. The tear line 5 and the through hole 4 are both created through punching; the tear line 5 can be created first, followed by the through hole 4. The tear line 5 is represented by a dashed line, indicating that the tear line 5 intermittently cuts the heat shrink film.

[0031] Figure 2 compared to Figure 6 , Figure 2It shows multiple interconnected chain-like structures. Figure 2 It contains three non-adhesive segments 7, and its total length is not fixed, nor is the number of non-adhesive segments 7. Figure 6 This shows what a single unit looks like.

[0032] like Figures 3 to 5 As shown, since heat shrink film is generally made of transparent material, Figures 3 to 5 The outline of battery 1, covered by heat-shrink film, is still visible in the image.

[0033] The beneficial effects of adopting the above technical solution are as follows: By arranging the adhesive section 6 and the non-adhesive section 7 alternately and cyclically along a straight line, a chain-like packaging structure for the battery 1 is achieved, meeting the hanging requirements, occupying little space, and stimulating purchasing desire. The easy-tear line 5 facilitates tearing off the unit, and the through hole 4 facilitates hanging. The non-adhesive section 7 still forms a side opening 8 after heat shrinking, which is both securely wrapped and easy to open, saving material costs.

[0034] In some other embodiments of this utility model, each non-adhesive segment 7 can accommodate a number of parallel-arranged batteries 1, the axial direction of the battery 1 is parallel to the length direction of the heat-shrinkable film, and the opening area of ​​the side opening 8 is smaller than the side-view projection area of ​​a single battery 1.

[0035] The main body of battery 1 is cylindrical, and one end of the battery is the positive contact 101. The side opening 8 does not expose the positive contact 101 of the adjacent battery 1.

[0036] Before and after the heat-shrink film shrinks due to heat, the opening area of ​​the side opening 8 also changes from large to small. After the heat-shrink film shrinks, the side opening 8 of the heat-shrink film fits tightly against the outer wall of the battery 1.

[0037] The beneficial effects of adopting the above technical solution are: each non-adhesive segment 7 can accommodate multiple parallel batteries 1, improving packaging efficiency. The side opening 8 has an area smaller than the side projection of the battery 1, preventing the battery from falling off and avoiding exposure of the positive electrode contact 101, thus ensuring safety.

[0038] In some other embodiments of this utility model, when the heat shrink film is not heated and shrunk, the two heat shrink films are long strip films of the same size and thickness.

[0039] The advantages of adopting the above technical solution are: the two heat shrink films are made of long strips of film with the same size and thickness, which simplifies the production process, reduces costs, and ensures packaging consistency and structural symmetry.

[0040] In some other embodiments of this utility model, when the heat shrink film is not heated and shrunk, the outline of the adhesive section 6 is rectangular, and the area occupied by the non-adhesive section 7 in the heat shrink film is greater than the area occupied by the adhesive section 6 in the heat shrink film.

[0041] The beneficial effects of adopting the above technical solution are: the area of ​​the non-bonded section 7 is larger than that of the bonded section 6, which ensures that there is enough space to accommodate the battery 1, and also ensures that the bonded area is firm and the structure is reasonable.

[0042] In some other embodiments of this utility model, when the heat-shrinkable film is not heated and shrunken, the length of the non-adhesive segment 7 is greater than the sum of the axial length of the single battery 1 and the diameter of the single battery 1.

[0043] The beneficial effects of adopting the above technical solution are: the length of the non-adhesive section 7 is greater than the axial length plus diameter of the battery 1, ensuring that there is enough space to completely wrap the battery 1, avoiding excessive compression after heat shrinking, and ensuring the integrity of the packaging.

[0044] In some other embodiments of this utility model, the tear line 5 extends laterally along the heat shrink film, and the tear line 5 divides the adhesive section 6 into two equal parts.

[0045] like Figures 4 to 6 As shown, the tear line 5 divides the adhesive section 6 into two parts after being torn open. The part that connects to the upper battery 1 is the lower film 702, and the part that connects to the lower battery 1 is the upper film 701.

[0046] The beneficial effects of adopting the above technical solution are: the easy-tear line 5 extends laterally and divides the adhesive section 6 into two equal parts, making the tearing operation more balanced and smooth, forming a symmetrical upper membrane 701 and lower membrane 702, which facilitates unit separation.

[0047] In some other embodiments of this utility model, the same adhesive section 6 has a plurality of through holes 4, which are symmetrically distributed on both sides of the easy-tear line 5.

[0048] The beneficial effects of adopting the above technical solution are: providing multiple suspension points, increasing suspension stability and flexibility, and facilitating display and retrieval.

[0049] like Figure 6 As shown, in some other embodiments of this utility model, the number of through holes 4 in the same adhesive segment 6 is four, and the vertical distance from each through hole 4 to the connected easy-tear line 5 is the same.

[0050] like Figure 4 As shown, the chain-like heat shrink film containing battery 1 can be folded along the tear line 5 when sold. The through holes 4 on both sides of the tear line 5 can be used for hooks to pass through, which can shorten the length of battery 1 when the whole chain is sold and displayed by half.

[0051] Consumers can, when purchasing, from Figure 3 Tear off a section from the middle, and you will get... Figure 5 .

[0052] The beneficial effects of adopting the above technical solution are: achieving a completely symmetrical layout, ensuring balance and stability when hanging, and aligning the through holes after folding, which facilitates compact display.

[0053] In some other embodiments of this utility model, the heat shrink film is made of POF, PET, OPS or PVDC material.

[0054] The beneficial effects of adopting the above technical solutions are as follows: POF, PET, OPS, and PVDC are respectively polyolefin heat shrink film, polyethylene terephthalate heat shrink film, oriented polystyrene heat shrink film, and polyvinylidene chloride heat shrink film. POF has excellent comprehensive performance, combining high transparency, high toughness, and environmental friendliness; PET has extremely high transparency, rigidity, and printability; OPS is environmentally friendly and has excellent gloss and rigidity; and PVDC has good oxygen and moisture barrier properties.

[0055] In some other embodiments of this utility model, the thickness of the heat shrink film is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0056] The advantages of adopting the above technical solution are: limiting the thickness of the heat-shrinkable film to the range of 12 to 37 micrometers, balancing mechanical strength and heat-shrinkability. If it is too thin, it will be easily damaged; if it is too thick, the shrinkage force will be insufficient.

[0057] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
