Description

Technical Field

[0001] This utility model relates to the field of bottled water seal film technology, and in particular to a bottled water semi-seal film with folded edges and openings. Background Technology

[0002] Plastic sealing film for bottled water is an important component used in bottled water packaging. Its main function is to protect the bottled water from contamination and leakage.

[0003] In traditional designs, after the plastic sealant is flattened, two perforations are usually made on it to allow users to apply even pressure when tearing the seal, making it easier to open. However, since the perforations are mostly located on the non-folded edges of the plastic sealant, two parallel perforating needles need to work simultaneously to create the perforations. This method increases equipment investment and production steps.

[0004] Furthermore, puncturing the sealing hole may also puncture the other side of the sealing film, affecting the overall sealing performance. This penetrating damage not only reduces the product's sealing performance but may also result in incomplete tearing or tearing in the wrong direction during the unsealing process, thus impacting the user experience.

[0005] To address the aforementioned shortcomings, a semi-sealed film for bottled water with folded edges and perforations is provided. Utility Model Content

[0006] The purpose of this utility model is to provide a semi-sealed film for bottled water with folded edges and openings in order to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A semi-sealed film for bottled water with folded edges and perforations, comprising:

[0009] Plastic sealing film: The plastic sealing film has a cylindrical structure;

[0010] Folded edge: formed on the plastic sealant film;

[0011] Tear-off structure: Provided on the plastic seal film and distributed along the folded edge.

[0012] Preferably, the plastic sealant is flattened under pressure to form a folded edge.

[0013] Preferably, the tear-off structure includes two perforations formed on the plastic sealant, and the two perforations are symmetrically distributed along the folded edge.

[0014] Preferably, the plastic sealant film is cut to form corresponding raised edges and recesses, and a tear line hole is formed through the raised edge.

[0015] Preferably, the plastic sealant has a partition with a different hardness than the plastic sealant.

[0016] Preferably, the dividing section includes an adhesive strip disposed on the plastic sealant film, the adhesive strip being harder than the plastic sealant film.

[0017] Preferably, the adhesive strip is a film made of polypropylene material.

[0018] Preferably, the dividing section is made of a material with weaker strength than the plastic sealant and is integrally formed with the plastic sealant.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this application, by placing the tear-off structure at the folded edge, the symmetrically distributed perforations allow users to apply force more evenly when tearing, reducing the difficulty of tearing and the risk of incomplete tearing. It also avoids the sealing problems caused by perforations penetrating the other side of the plastic seal in traditional designs. Furthermore, the design of the raised edge and recess makes it easier for users to find the starting point for tearing, resulting in a cleaner tear and improving the product's aesthetics and practicality, significantly optimizing the user experience.

[0021] 2. In this application, the dividing section uses a material with a different hardness than the plastic sealing film (such as an adhesive strip made of polypropylene), and through the design of strong and weak partitions, the convenience of tearing the seal and the aesthetics of the seal are further improved.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 and Figure 2This utility model provides a technical solution: a semi-sealed film for bottled water with folded edges and perforations, comprising:

[0028] Plastic sealing film 1: Plastic sealing film 1 has a cylindrical structure;

[0029] Folded edge: formed on the plastic sealant 1;

[0030] Tear-off structure: set on the plastic seal 1 and distributed along the folded edge.

[0031] The plastic seal 1 has a cylindrical structure and is the basic part of the entire seal. The tear-off structure is set on the plastic seal 1 and distributed along the folded edge, making it more convenient for users to tear open the plastic seal 1 and reducing the difficulty of tearing.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the plastic sealant 1 is flattened under pressure to form a folded edge. The tear-off structure includes two perforations 3 on the plastic sealant 1, which are symmetrically distributed along the folded edge. Corresponding protrusions 2 and notches 4 are formed on the plastic sealant 1 by cutting, and the perforations 3 are torn through the protrusions 2.

[0033] Two thread holes 3 are symmetrically distributed along the folded edge. This symmetrical design helps users apply force more evenly, making it easier to tear open the seal. Corresponding convex edges 2 and notches 4 are formed by cutting. The convex edges 2 are used to tear the thread holes 3. This design further optimizes the convenience of tearing the seal.

[0034] In traditional designs, if the hole 3 is punctured, the other side of the sealing film 1 may also be punctured, affecting the overall strength and sealing performance of the film. This penetrating damage not only reduces the product's sealing performance but may also result in incomplete tearing or tearing in the wrong direction during the unsealing process, impacting the user experience.

[0035] This technical solution avoids penetrating damage by placing the wire holes 3 at the folded edge, utilizing the structural characteristics of the folded edge. Furthermore, in traditional designs, achieving two symmetrically distributed wire holes 3 typically requires two perforation processes, increasing equipment investment and extending production steps and time. This technical solution, however, requires only one perforation needle operation to achieve the symmetrical distribution of two wire holes 3, significantly simplifying the production process.

[0036] Specifically, such as Figure 2 As shown, the laminating film 1 has a dividing section with a different hardness than the laminating film 1. The dividing section includes an adhesive strip 5 disposed on the laminating film 1, and the adhesive strip 5 has a higher hardness than the laminating film 1. The adhesive strip 5 is a film made of polypropylene material.

[0037] Polypropylene material has good compatibility with plastic sealing film 1 and can be firmly bonded by means of hot pressing or adhesive. By setting strong and weak zones in plastic sealing film 1, the flatness of the tear in plastic sealing film 1 can be guaranteed when the seal is torn, and irregular tearing can be avoided during the tearing process, thus improving the aesthetics and practicality of the seal.

[0038] Transparent films made of polypropylene are called "OPP materials". Polypropylene films prepared by biaxial stretching process have the advantages of being non-toxic, odorless, and environmentally friendly, meeting environmental protection requirements. They also have excellent transparency, tear resistance and moisture resistance.

[0039] The dividing section uses a material with weaker strength than the plastic sealant 1, and is integrally molded with the plastic sealant 1.

[0040] Because the strength of the dividing section is relatively low, users can easily tear along the dividing section when tearing the seal, which serves as a guide and makes tearing the seal more convenient. The lower strength material requires less force when tearing the seal, reducing the difficulty for users to tear the seal and improving the user experience. In addition, it can form a neat tear when tearing the seal, avoiding damage to the plastic film 1 caused by uneven tearing.

[0041] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
