Description

Technical Field

[0001] This utility model relates to the field of packaging and sealing adhesive technology, and more specifically, to an easy-tear sealing adhesive and packaging suitable for products such as wet wipes and paper towels. Background Technology

[0002] The sealing sticker on a wet wipe bag is a sealing sticker used to close the dispensing opening on wet wipe packaging. Traditional sealing stickers are generally single-layered. Because wet wipe labels are repeatedly torn and pasted during use, they tend to lose their adhesion. With the development of wet wipe packaging technology, wet wipe packaging now commonly includes a wet wipe cap to seal the dispensing opening. However, the wet wipe label is still retained during production, packaging, and transportation to maintain the integrity and good sealing of the packaging bag. When unpacking and using the wet wipes, the wet wipe label can be completely removed, and only the wet wipe cap needs to be used to seal the bag.

[0003] In the prior art, referring to patent documents with publication numbers CN214325912U and CN203033106U, the label tear-off end is close to the inner edge of the wet wipe cover. The inner edge of the wet wipe cover has a certain thickness, making it difficult for users to easily insert their fingers and pinch the label end. Furthermore, the tear-off end occupies space, making it inconvenient to make the wet wipe dispensing opening larger. See the appendix to patent application document with publication number CN 117508902 A. Figure 1-3 The label tear-off part 3a has a certain space reserved between the label tear-off part 3a and the inner edge of the wet wipe cover, which makes it easy to tear by hand. However, the size of the extraction opening 2 is limited, and the small extraction opening makes it inconvenient to extract the wet wipe.

[0004] In view of this, the applicant has innovatively designed the easy-tear sealing adhesive and packaging of this application, aiming to make the label easier to tear off and to make the dispensing opening inside the wet wipe cap larger, making it easier to take out the wet wipes, by improving the structure of the sealing adhesive. Utility Model Content

[0005] The purpose of this invention is to provide an easy-tear sealing adhesive and packaging with the easy-tear sealing adhesive to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An easy-tear sealing adhesive tape includes a first adhesive tape and a second adhesive tape. The first adhesive tape includes an annular portion and a pull tab. The annular portion is adhered to the edge of the second adhesive tape, and the pull tab is located in the middle of the second adhesive tape, extending to the annular portion. One side of the pull tab connects to the inner side of the annular portion, and the other side connects to the outer side of the annular portion. An easy-tear line is provided between the pull tab and the annular portion on the side where the pull tab connects to the outer side of the annular portion. This side of the pull tab extends to and connects to the outer side of the annular portion through the easy-tear line. When the annular portion is torn off, it rotates circumferentially along the second adhesive tape and separates from it. The tail end or near the tail end of the annular portion is strongly adhered to the second adhesive tape, so that the second adhesive tape can be lifted and torn off by the first adhesive tape.

[0007] The part where the annular portion is strongly bonded to the second adhesive is located at one end of the second adhesive, making it easier and less strenuous to peel off the second adhesive from the end.

[0008] The end of the pull tab has a de-adhesive structure.

[0009] The two sides of the pull tab extend into the annular part with arc-shaped sides to reduce tearing resistance and make the connection and movement of the annular part smoother when the pull tab is opened.

[0010] A type of packaging includes a packaging body with a dispensing opening. An easy-tear sealing adhesive is provided at the dispensing opening, and at least the second adhesive part of the easy-tear sealing adhesive is adhered to the edge of the dispensing opening to achieve adhesive closure of the dispensing opening.

[0011] The outer edge of the first adhesive sticker is a certain distance larger than the outer edge of the second adhesive sticker, and is adhered to the packaging body.

[0012] This invention, through the above-described solution, positions the pull tab for opening the label in the middle, making the pinching operation during label opening more convenient and easier. The outer edge of the first adhesive label can be flush with the outer edge of the second adhesive label; preferably, the outer edge of the first adhesive label is larger than the outer edge of the second adhesive label when it is bonded to the packaging body. This reduces the bonding area between the second adhesive label and the packaging body. By having both the first and second adhesive labels bonded to the packaging body, the area and strength of the seal are ensured. When opening, the adhesive surface between the first adhesive label and the packaging body is first peeled off. By the time the second adhesive label is peeled off, the adhesive surface between the label and the packaging body has been reduced, making the second adhesive label easier and less strenuous to remove, thus achieving the goal of easier removal.

[0013] In addition, by placing the pull tab for opening the package in the middle of the label, this invention reduces space usage compared to the traditional structure with the tab at the end. This allows for a larger opening, making it easier to remove the wet wipes and avoiding problems such as repeated removal or difficulty in removing them.

[0014] This utility model has the characteristics of simple structure, strong practicality and good use effect, and is worth promoting and using widely. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] A packaging package includes a packaging body with a dispensing opening. An easy-tear sealing adhesive tape is provided at the dispensing opening. The easy-tear sealing adhesive tape includes a first adhesive tape and a second adhesive tape. The first adhesive tape includes an integrally connected annular portion and a pull tab. The annular portion is adhered to the edge of the second adhesive tape. The pull tab is located in the middle of the second adhesive tape and extends to the annular portion. One side of the pull tab connects to the inner side of the annular portion, and the other side connects to the outer side of the annular portion. An easy-tear line is provided between the pull tab and the annular portion on the side where the pull tab connects to the outer side of the annular portion. This easy-tear line extends to and connects with the outer side of the annular portion. When the annular portion is torn, it rotates circumferentially along the second adhesive tape and separates from it. The tail end or near the tail end of the annular portion is strongly adhered to the second adhesive tape, allowing the second adhesive tape to be lifted and torn off by the first adhesive tape. The easy-tear sealing adhesive tape, at least its second adhesive tape, is adhered to the edge of the dispensing opening, achieving a sealed closure of the dispensing opening.

[0018] For details, please refer to Figure 1-4Let's take one of our company's wet wipes products as an example. The packaging of this wet wipe product includes a packaging body 1 and a wet wipe cover 2 set on the packaging body 1. An easy-tear sealing adhesive is set inside the wet wipe cover 2 at the dispensing opening 3 of the packaging body 1 to achieve adhesive sealing of the dispensing opening.

[0019] The easy-tear sealing adhesive includes a first adhesive sticker 5 and a second adhesive sticker 4. The first adhesive sticker 5 includes an integrally connected annular portion 52 and a pull tab 51. The annular portion 52 is adhered to the edge of the second adhesive sticker 4. Figure 1 The outer edge of the first adhesive sticker 5 is flush with the outer edge of the second adhesive sticker 4. The easy-tear sealing adhesive sticker is only attached to the edge of the dispensing opening 3 of the packaging body 1 by the second adhesive sticker 4, so as to achieve the adhesive sealing of the dispensing opening 4. Figure 2 The outer edge of the first adhesive sticker 5 is a certain distance larger than the outer edge of the second adhesive sticker 4, and is pasted to the packaging body 1.

[0020] In actual production applications, the opening 3 of the packaging body 1 has a cut-off portion, and the inner side of the second adhesive 4, which is pasted to the edge of the opening 3, is bonded to the cut-off portion of the packaging body 1.

[0021] The pull tab 51 of the first adhesive label 5 is located in the middle of the second adhesive label 4, and preferably the pull tab 51 has an adhesive-removing structure for easy pinching and tearing. The pull tab 51 extends to the annular portion 52, with one side connecting to the inner side of the annular portion 52 and the other side connecting to the outer side of the annular portion 52. Preferably, both sides of the pull tab 51 extend to the annular portion 52 with curved sides, which helps to reduce tearing resistance and makes it easier to connect and pull the annular portion 52 when the pull tab is opened. An easy-tear line 53 is provided between the side of the pull tab 51 that connects to the outer side of the annular portion 52 and the annular portion 52 (see...). Figure 2 , Figure 3 The side of the pull tab 51 extends to the outer side of the annular portion 52 via the easy-tear line 53 and connects with it. When the pull tab 51 is pulled up to tear the annular portion 52, the annular portion 52 breaks at the easy-tear line 53 and rotates circumferentially along the second adhesive 4 to separate from the second adhesive 4. A strong adhesive part 6 with strong adhesion is provided at or near the tail end of the annular portion 52 and the second adhesive 4. Other adhesive parts between the first adhesive 5 and the second adhesive 4 are bonded with release adhesive or self-adhesive adhesive with relatively weak adhesion to facilitate the separation of the first adhesive 5 from the second adhesive 4 when it is torn along the annular portion 52. When separated to or near the tail end, the first adhesive 5 lifts up the second adhesive 4 and tears it off through the strong adhesive part 6.

[0022] Figure 5 The example shows that the annular portion 52 and the strong adhesive portion 6 of the second adhesive 4 are located at one end of the second adhesive 4, which facilitates peeling off the second adhesive 4 from the end of the second adhesive 4.

[0023] See Figure 6and Figure 7 Compared to existing technologies, within the same size wet wipe cap, the wet wipe dispensing opening of this application can be increased in both length and width by 10mm compared to the traditional label's wet wipe dispensing opening, significantly increasing the size of the wet wipe dispensing opening and making it more convenient to extract the wet wipes. The pull tab 51 for opening the package is located in the middle of the label and the wet wipe cap, making the pinching operation during label opening more convenient and easier. Preferably, the outer edge of the first adhesive label 5 and the second adhesive label 4 are jointly adhered to the packaging body 1. While ensuring the area and strength of the sealed adhesion, the adhesive area between the second adhesive label 4 and the packaging body 1 can be reduced. When opening, the adhesive surface between the first adhesive label 5 and the packaging body 1 is first torn off. When the second adhesive label 4 is torn off, the adhesive surface between the label and the packaging body 1 has been reduced, making the entire label tearing process easier and less strenuous, further improving the easy-to-tear effect.

[0024] According to experimental statistics, the success rate of opening this application reaches 99.5%, which is much higher than the approximately 85% of traditional labels. The area of ​​the wet wipe dispensing opening can be effectively increased by more than 40%, significantly improving the convenience of wet wipe dispensing.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
