New description: [New technical field] The present invention provides a sealing film structure, in particular, a sealing film structure which is technically provided to be easily peeled off and does not cause a part of the sealing film to remain on the bottle mouth. [Prior Art] According to the conventional sealing film structure, the film is usually sealed twice. The first sealing film can only make the sealing film slightly melted on the bottle mouth, and the adhesion is not enough, and the contents of the bottle body may be Leaking out, the second sealing can completely melt the sealing film on the bottle mouth to form a complete tightness, so that the contents of the bottle will not leak out. However, please refer to the seventh and eighth figures of the 'sealing membrane structure'. The sealing film has a sealing area corresponding to the mouth of the bottle (3 2 ) (3 ′, the sealing area (33) is melted by the machine. In the mouth of the bottle, jz), it will be slightly thinner than other areas of the sealing film, and the complete 埶 (4) formed by the 犋 can be squeezed out to the factory and is not easily torn completely from the mouth (32): The sealing film remains at the mouth of the bottle 丄μ \ ), so that the seal is spliced. (10) The sealing film (31) and the partially sealed seal ") are opened, which is inconvenient for the user. (3〇, for the above-mentioned conventional structure exists - an innovative structure with more ideal practicability, real consumption: He development is also the relevant industry to strive to develop breakthrough goals and directions are eagerly awaited, 3 024 In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the creator has finally made a practical application. [New content] Technology to be solved Problem: The sealing film structure used in the past, due to the complete heat generation caused by the second sealing film, the sealing film is not easily torn completely from the mouth of the bottle. It is easy to have a part of the sealing film remaining at the mouth of the bottle, so that the sealing film is formed. The tearing of the sealing film and the partially remaining sealing film cause inconvenience to the user. Technical problem of the problem: providing a sealing film structure comprising an opening m covering the opening of the container or a soft bag, the sealing The film is a heat-fusible sealing 臈, the outer shape of the sealing 臈 is larger than the inner circumference of the opening of the container, and the sealing film corresponds to the outer circumference of the opening of the container to the container The inner periphery of the mouth is a hot-melt sealing area'. The sealing film is a sealing film with a large area of sealing area and a small area sealing area, and the sealing area of the sealing area is the hot-sealing sealing area all of the small area of the sealing film. The sealing area corresponds to the inner circumference to the outer circumference of the opening of the container and is smaller than the total heat sealing area. Effect: The sealing film structure of the present invention has a second sealing film which is only partially melted near the inner circumference of the opening. Wherein, the outer peripheral edge of the sealing film is still (4) torn apart 4 will be partially residual to produce the technology, means and efficacy of the present invention in relation to the prior art, and the preferred embodiment and the figure The formula is detailed in €, and it is believed that the above-mentioned purpose, structure and characteristics of the present invention can be obtained from an in-depth and specific understanding. [Embodiment] Referring to the first to sixth figures, the present invention provides a sealing film structure. And comprising: a sealing film (1) covering an opening (2i) of a container (20), the sealing film (1) being a heat-sealable sealing film (1), the sealing film (1) having a peripheral shape larger than, etc. The container (2 〇) to be sealed is opened. (21) The outer circumference (2 (1) or the sealing film (1) has a peripheral shape larger than the opening of the container (2 2) to be sealed (perimeter (2 1 2 ) and smaller than the container ( 2 〇w & υ j opening ( 2 ί , corresponding volume .... 2: ) inner circumference (2 1 edge (2 1 1 ) to the container (2 〇) opening ° (2 1 2) is the hot melt sealing area (1 ο ) , 1 ) Λ is a 4· ζ , 丄 U ), the sealing film ( : ~, ® product sealing area and - small area sealing area (1) 'the sealing film (1) large area sealing area...: The sealing film (1〇) is all, the sealing area is opposite to the person, 1) the small area sealing area Γ 19, • The container (2〇) opening (to the outer circumference (2丄), the inner circumference (2 1 2 ) Ο ) μ, and less than the total heat sealing mouth domain r, 〇). Thereby, the sealing film (1) can be easily torn off (1 container (20) μ] without remaining on the opening (21). Wherein the 'D gift, the multi-layered seal (1) can be The sealing film (1) composed of a single layer is formed into a sealing film (1) (as shown in Fig. 6. M410024, wherein the sealing film (1) may not require a pull ear (11), and may also be provided with a pull ear (1 1 ). The container (20) can be a bottle body (as shown in the first figure). wherein the device (20) is a jelly box (as shown in the second figure, the container (20) can be a soft bag. (The figure is not shown.) The above structure is formed by two sealing films, the first sealing film is hot pressed all the sealing area (1 ◦), and the second sealing film is not hot pressed all the hot sealing The area (1 〇) is only hot pressed to the opening ( 2 i ) close to the inner circumference (212) area' so the sealing film ( 1 ) in the outer peripheral edge (21 1) area is not very sticky and heat soluble in the opening ( 2 1 The sealing film (1) in the outer peripheral edge (2 1 1 ) is easily torn, so that the sealing film (1) does not easily remain at the opening (21). The preferred embodiments are specifically described in the technical features of the present invention; those who are familiar with the technology can change and modify the creation under the spirit and principle of the two creations, and the changes and modifications should be It is covered in the following definitions (4) in the definition of Fan Luo.
