[0018] To fully understand the purpose, features and effects of the present invention, the present invention is described in detail with reference to the following specific embodiments and the accompanying drawings.

[0019] Please refer to Figures 1 to 5. As shown in the figures, the present invention provides a container sealing structure 1, which includes: a cover 11, a first tear line 12, a first sealing portion 13 and a first removal portion 14.

[0020] The cover 11 includes a first adhesive film 111 , a paper layer 112 , and a second adhesive film 113 . The paper layer 112 is laminated and bonded to the top surface of the first adhesive film 111 , and the second adhesive film 113 is laminated and bonded to the top surface of the paper layer 112 .

[0021] The first tear line 12 is provided on the cover 11 and connects the second adhesive film 113 , the paper layer 112 , and the first adhesive film 111 .

[0022] The first sealing portion 13 is removably disposed on the cover 11 and is located inside the first tear line 12 .

[0023] The first removal portion 14 includes a coupling end 141 and a force-applying end 142. The coupling end 141 couples the second film 113 and the first sealing portion 13. The force-applying end 142 is disposed on one side of the coupling end 141. The first removal portion 14 removes the first sealing portion 13 to form a first opening 114 in the cover 11.

[0024] When in use, the cover 11 can be positioned with the first adhesive film 111 corresponding to the opening 21 of a container 2, and then the first adhesive film 111 can be bonded to the top surface of the opening 21 by heat pressing, thereby sealing the opening 21 of the container 2 with the cover 11. In this way, the cover 11 can be firmly sealed to the opening 21 of the container 2 by heat pressing, thereby preventing the container 2 from moving or tipping over and causing the beverage to spill.

[0025] When the user wishes to drink the beverage in the container 2, they apply a pulling force to the force-applying end 142 of the first removal portion 14. This force-applying end 142 cooperates with the coupling end 141 and the first tear line 12 to pull up the first sealing portion 13. This pulls up the first sealing portion 13 and simultaneously removes it in conjunction with the first tear line 12. After the first sealing portion 13 is removed, the lid 11 reveals the first opening 114, allowing the user to drink directly from the first opening 114 or insert a straw into the first opening 114. In this way, the lid 11 is securely sealed to the opening 21 of the container 2 by heat and pressure, preventing the container 2 from spilling due to movement or tipping. Furthermore, the disposable first sealing portion 13 provides a barrier to opening and illicit drinking.

[0026] Furthermore, since the cover 11 is formed by laminating the first film 111, the paper layer 112, and the second film 113, the cover 11 has a thin design. Therefore, when not in use, the cover 11 can be stacked on top of each other due to its thin design, achieving the effect of easy storage and collection.

[0027] In addition to the above embodiment, in another embodiment of the present invention, the first film 111 is low-temperature linear low-density polyethylene (PE), the paper layer is waterproof paper, and the second film is polypropylene (PP) or polyethylene terephthalate (PET). This ensures that the first film 111, the paper layer 112, and the second film 113 are laminated and bonded together, preventing them from separating. The multi-layer, thin design also provides the cover 11 with improved support and stiffness. When not in use, the thin design of the cover 11 allows for easy storage and storage.

[0028] In addition to the above embodiments, in one embodiment of the present invention, the first adhesive film 111 and the second adhesive film 113 are light-transmissive, and a pattern area 115 is provided on the top surface of the paper layer 112. The pattern area 115 may include animal images, plant images, geometric images, numbers, or text, so that the cover 11 can meet the advertising needs of various stores. Since the paper layer 112 can be waterproof paper, not only can the paper layer 112 be easily bonded to the first adhesive film 111 and the second adhesive film 113, but the pattern area 115 can also be easily printed on the paper layer 112, and the pattern area 115 is not easily blurred by moisture.

[0029] In addition to the above embodiment, in another embodiment of the present invention, the coupling end 141 couples the second adhesive film 113 and the first sealing portion 13 with acrylic adhesive. This allows the first removable portion 14 to be securely coupled to the second adhesive film 113 and the first sealing portion 13. By applying force to the force-applying end 142 to pull up the first removable portion 14, the coupling end 141 cooperates with the first tear line 12 to pull up the first sealing portion 13, facilitating removal of the first sealing portion 13 and revealing the first opening 114, thereby achieving ease of operation.

[0030] In addition to the above embodiment, in another embodiment of the present invention, a release layer 143 is provided at the bottom of the force-applying end 142, so that the force-applying end 142 is prevented from adhering to the second adhesive film 113 by the release layer 143. In this way, the release layer 143 can be utilized to apply force to the force-applying end 142 of the first removal portion 14, thereby achieving the effect of easy operation and use.

[0031] In addition to the above embodiment, in another embodiment of the present invention, the cover 11 is provided with a vent 116 that connects the first film 111, the paper layer 112, and the second film 113. In this way, the vent 116 can be used not only to vent the beverage in the container 2 but also to directly insert a straw, making the present invention more suitable for practical applications.

[0032] Please refer to Figures 6 and 7. As shown in the figures, in addition to the above embodiments, in one embodiment of the present invention, a second tear line 15 and a second sealing portion 16 are further included. The second tear line 15 is provided on the cover 11 and connects the second film 113, the paper layer 112, and the first film 111. The second sealing portion 16 is removably provided on the cover 11 and is located inside the second tear line 15. Removing the second sealing portion 16 forms a second opening portion 117, wherein the vent 116 is located on the second sealing portion 16 and connects the first film 111, the paper layer 112, and the second film 113.

[0033] Based on the above embodiment, in addition to utilizing the vent 116 as a vent for the beverage in the container 2, a straw can also be directly inserted into the corresponding position of the vent 116, so that the second sealing portion 16 is subjected to the external force of the straw and folds downward in conjunction with the second tear line 15. The second sealing portion 16 is removed from the cover 11 to form the second opening 117, which can be used as a position for inserting the straw. This makes the present invention more suitable for practical application needs.

[0034] Please refer to Figures 8 and 9. As shown in the figures, in addition to the above-mentioned embodiments, in one embodiment of the present invention, the outer edge of the cover 11 is provided with at least one picking portion 17. The picking portion 17 can be integrally formed or assembled with the outer edge of the cover 11. Since a plurality of covers 11 can be stacked on each other in the present invention to achieve the effect of easy collection and storage, when taking out the cover 11, force can be applied to the picking portion 17 to take out the cover 11 at the opening 21 of the container 2, thereby avoiding direct contact of the hand with the first film 111 of the cover 11, thereby meeting the requirements of hygiene when taking out the cover 11.

[0035] In addition, the number of the pick-up portions 17 can be one, two, or more. In addition to allowing the cover 11 to meet hygiene requirements by utilizing the pick-up portions 17, a single or multiple pick-up portions 17 can be combined with the pattern area 115 to give the cover 11 an aesthetically pleasing shape (for example, the cover 11 can be combined with the pick-up portions 17 to form an animal shape).

[0036] Please refer to Figures 10 and 11. As shown in the figures, in addition to the above embodiment, in one embodiment of the present invention, the second opening portion 117 is provided on the paper layer 112, and the first adhesive film 111 closes the bottom of the second opening portion 117, the second adhesive film 113 closes the top of the second opening portion 117, and the vent 116 communicates with the first adhesive film 111, the second opening portion 117 and the second adhesive film 113; thus, the second opening portion 117 cooperates with the light-transmissive first adhesive film 111 and the second adhesive film 113, so that the cover 11 has a transparent The beverage container 2 has a viewing window for viewing the type of beverage in the beverage container 2. When drinking, in addition to applying force on the first removal portion 14 to remove the first sealing portion 13 and drink from the first opening 114, a straw can also be directly inserted into the first film 111 above the second opening 117. The straw passes through the first film 111, the second opening 117, and the second film 113, and the second opening 117 is used as the insertion position for drinking. This achieves the effect of easy operation and makes the present invention more suitable for practical application needs.
