Description

Technical Field

[0001] The invention relates to a sealing film, in particular to an easy-to-tear sealing film for bottled water. Background Art

[0002] The existing bottled water outlet is often provided with a sealing film, the function of the sealing film is to prevent dust from entering the barrel and thus contaminating the water in the barrel, and the existing sealing films are tightly attached to the water outlet of the bottled water, and it is troublesome to tear and remove them during use, and often requires the use of scissors or a knife to remove them. Therefore, it is extremely inconvenient to use. Although the existing sealing film is also provided with a cutout for conveniently tearing the sealing film, the position of the cutout design is located on the side of the sealing film. Since the sealing film is a single-layer film structure, when it is torn from the cutout, it is easy to cause the torn opening to deviate from the route, and the sealing film cannot be completely torn off. Therefore, in actual use, the effect is greatly reduced.

[0003] The invention provides an easy-to-tear sealing film, which has a simple design and is convenient to tear, and is suitable for a wide range of applications. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an easy-to-tear sealing film for bottled water.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] A fully sealed and tearable sealing film for bottled water is a cylindrical structure with an open lower end, which is made by folding the sealing film in an integrated manner and then bonding the folded joints together by hot melting. The sealing film comprises an outer edge area and a barrel area, wherein a central area is bonded in the middle of the outer edge area by hot melting, and two parallel cutting lines are arranged on the central area, the outer edge area and the barrel area.

[0007] An incision is arranged at the upper end of the joint of the sealing film, and the two ends of the incision are connected to the cutting lines at both sides.

[0008] The position of the incision is the connection point between the barrel area and the outer edge area.

[0009] The front end of the incision is pointed.

[0010] The central area is a transparent area.

[0011] The sealing film is made of food-grade PE material.

[0012] The lower end opening of the sealing film is larger than the opening of the bottled water. When in use, the sealing film is first put on the opening of the bottled water, and then the sealing film is heated by a hair dryer so that it only fits on the opening of the bottled water.

[0013] The beneficial effect of the present invention is that by setting an incision at the connection point between the outer edge area and the barrel area, and connecting with two parallel cutting lines, and the incision is located at the joint of the sealing film, the joint is a double-layer film structure, the user can easily start from the incision and smoothly tear the sealing film along the cutting line, and when tearing, it will not cause the tearing route to deviate, which greatly improves the convenience and safety of use. The front end of the incision is designed to be pointed, which is more convenient for the user to tear and pull at the beginning, reducing the difficulty of tearing the sealing film.

[0014] Although the sealing film is designed to be easy to tear, its overall structure - folded in one piece and made into a cylindrical structure through hot-melt bonding - ensures that the sealing film can form a good sealing effect when it fits the opening of the bottled water, effectively preventing pollutants such as dust and bacteria from entering the barrel, and ensuring the hygiene and safety of drinking water.

[0015] The center area is designed to be transparent, allowing users to vaguely observe the condition of the water in the bucket before tearing off the sealing film, which increases the transparency and sense of security during use.

[0016] The sealing film is made of food-grade PE material, which is non-toxic, odorless, and environmentally friendly. It meets the hygiene standards for drinking water packaging materials and ensures the safety and health of drinking water.

[0017] The sealing film is simple and practical in design. It is not only suitable for bottled water, but can also be widely used in other liquid products that require sealed packaging. It has broad market application prospects.

[0018] In summary, the bottled water easy-to-tear sealing film of the present invention shows significant beneficial effects in improving user experience, ensuring sealing performance, protecting drinking water health, and expanding the scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0021] A fully sealed and tearable sealing film for bottled water is a cylindrical structure with an open lower end, which is made by folding the sealing film in an integrated manner and then bonding the folded joints together by hot melting. The sealing film comprises an outer edge area 1 and a barrel area 2. A central area 3 is bonded in the middle of the outer edge area 1 by hot melting. Two parallel cutting lines 4 are provided on the central area 3, the outer edge area 1 and the barrel area 2.

[0022] A notch 5 is provided at the upper end of the joint of the sealing film, and both ends of the notch 5 are connected to the cutting lines 4 on both sides.

[0023] The position of the cutout 5 is the connection point between the barrel area 2 and the outer edge area 1 .

[0024] The front end of the incision 5 is pointed.

[0025] The central area 3 is a transparent area.

[0026] The sealing film is made of food-grade PE material.

[0027] The lower end opening of the sealing film is larger than the opening of the bottled water. When in use, the sealing film is first put on the opening of the bottled water, and then the sealing film is heated by a hair dryer so that it only fits on the opening of the bottled water.

[0028] The implementation principle of the present invention:

[0029] 1. Structural design and production principle

[0030] This fully sealed and easy-to-tear sealing film for bottled water adopts an integrated folding design. By bonding the folded joints together through hot-melt technology, a cylindrical structure with an open lower end is formed. This design not only simplifies the production process of the sealing film, but also ensures the integrity and strength of the sealing film. The sealing film includes an outer edge area 1 and a barrel area 2, wherein a central area 3 is bonded in the middle of the outer edge area 1 by hot-melt bonding. The design of the central area 3 not only enhances the stability of the sealing film, but also provides a reliable support point for subsequent hot-melt bonding. Two parallel cutting lines 4 are provided on the central area 3, the outer edge area 1 and the barrel area 2, which provide a clear path for the subsequent tearing operation.

[0031] 2. Easy-tear design principle

[0032] A cutout 5 is specially provided at the upper end of the joint of the sealing film. The position of the cutout 5 is carefully selected at the connection point between the barrel area 2 and the outer edge area 1. This design allows the user to easily start the tearing operation from this position. The front end of the cutout 5 is pointed. This shape design further reduces the difficulty of tearing, allowing the user to more easily tear the sealing film along the cutting line 4. At the same time, because the cutout 5 is connected to the cutting line 4, the user can keep the tearing path stable when tearing, and it is not easy to deviate from the predetermined route.

[0033] 3. Lamination and sealing principle

[0034] The sealing film is made of food-grade PE material, which has good flexibility and plasticity. When using it, the user only needs to put the lower opening of the sealing film on the opening of the bottled water, and then heat the sealing film with a hair dryer. The heated sealing film will soften and fit tightly to the opening of the bottled water, forming a tight sealing layer. This sealing layer can effectively prevent dust, bacteria and other pollutants from entering the barrel, ensuring the hygiene and safety of drinking water.

[0035] 4. Design principles of transparent central area

[0036] The central area 3 is designed as a transparent area, which allows the user to vaguely observe the condition of the water in the bucket before tearing off the sealing film. This increases the transparency and sense of security during use, allowing the user to more intuitively understand the quality and condition of the water in the bucket.

[0037] In summary, this bottled water full-seal easy-tear sealing film achieves a perfect combination of easy tearing and sealing properties through ingenious structural design and easy-tear design principle. At the same time, the use of food-grade PE material and transparent center area design further enhances the safety and practicality of the product.
