[0002] Easy-tear caps are a new type of cap made using a composite technology that bonds aluminum foil to tinplate or a coated metal substrate. They feature high sealing performance and a certain degree of pressure resistance. They can be opened without any tools; simply tear them open by hand.

[0003] Easy-tear lids are classified into two types based on their handle: pull-tab lids and pull-ring lids. Pull-tab lids have a sheet of aluminum foil as the handle. However, the uneven force applied when pulling the foil makes it difficult to open, and the thin foil can easily cut hands. Pull-ring lids, on the other hand, have a pull ring design that greatly improves the evenness of force distribution, making them easier for consumers to open. However, during production and storage, pull-ring lids often suffer from defects such as the pull ring not being properly secured, leading to problems like it lifting or becoming damaged, affecting their normal use.

[0004] Based on this, an easy-tear cap with a fixed pull ring is designed. On the one hand, the pull ring is safe and convenient for opening the easy-tear cap. On the other hand, the pull ring is fixed to the easy-tear cap, eliminating problems such as the pull ring lifting or being damaged. Utility Model Content

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-2 As shown, an easy-tear cap with a fixed pull ring includes an aluminum foil 2 that is sealed and covered on a ring cap 1. A pull ring 3 extends outward from the side of the aluminum foil 2 away from the ring cap 1. The pull ring 3 includes a connecting part 31, a through hole 32, and a positioning part 33. A fixing part 331 that can be bonded to the aluminum foil 2 is attached to the positioning part 33. The pull ring 3 can be positioned away from the aluminum foil 2 or folded and attached to the aluminum foil 2 by the fixing part 331.

[0025] Specifically, during normal production and transportation processes, such as Figure 1 The pull ring 3 is folded and attached to the aluminum foil 2 by the fixing part 331, which prevents the pull ring 3 from lifting, deforming, or being damaged under external force, thus affecting the use of the easy-tear cap; when the pull ring 3 is in normal use, such as Figure 2 The fixing part 331 is detached from the aluminum foil 2. Correspondingly, the pull ring 3 is set away from the aluminum foil 2. The finger passes through the pull ring through hole 32 and applies force in the direction of the aluminum foil 2, so that the aluminum foil 2 is detached from the ring cover 1, thus completing the opening of the ring cover 1.

[0026] The pull ring 3 of this utility model is bonded to the aluminum foil 2 at the fixing part 331, which makes the pull ring 3 less prone to lifting or damage during production and transportation, thus ensuring the performance of the pull ring 3. Secondly, when the fixing part 331 of the pull ring 3 is detached from the aluminum foil 2, the aluminum foil can be easily peeled off by the pull ring 3 to open the ring cover 1.

[0027] The width of the positioning part 33 is between 3 and 6 mm, and the fixing part 331 is located on the positioning part 33, which limits the area of ​​the fixing part 331 on the positioning part 33.

[0028] Adhesive is applied to the fixing part 331 or adhesive is applied to the aluminum foil 2 corresponding to the fixing part 331.

[0029] The central axis of the fixing part 331 is coaxially arranged with the central axis of the pull ring 3, which makes it easy to determine the position of the fixing part 331.

[0030] Specifically, the fixing part 331 is a circle marked on the positioning part 33, which is adjusted according to the size of the positioning part 33; the fixing part 331 has adhesive on the side facing the aluminum foil 2 to facilitate the fixing part 331 to be bonded to the aluminum foil 2, or the aluminum foil 2 has adhesive on the side facing the fixing part 331 to facilitate bonding with the corresponding fixing part 331, thereby making the pull ring 3 folded and attached to the aluminum foil 2, preventing the pull ring 3 from lifting, deforming and being damaged under the action of external force.

[0031] Furthermore, the positioning part 33 with a width of 3-6mm determines the diameter of the fixing part 331 located thereon, thereby increasing the bonding area between the fixing part 331 and the aluminum foil 2, ensuring that the pull ring 3 can be stably folded and attached to the aluminum foil 2.

[0032] like Figures 1-2 As shown, the central axis of the pull ring 3 is coaxially arranged with the central axis of the aluminum foil 2; the through hole 32 is located between the connecting part 31 and the positioning part 33. The central axis of the through hole 32 is coaxially arranged with the central axis of the pull ring 3. Therefore, when an external force is applied to the pull ring 3 through the through hole 32, the forces on both sides of the aluminum foil 2 are the same, which is conducive to the aluminum foil 2 being torn open stably.

[0033] The inner edge of the through hole 32 is rolled outward to form the through hole rolled edge 321.

[0034] The connecting part 31 has symmetrically arranged arc-shaped openings 311 for positioning on the side near the aluminum foil 2.

[0035] The outer edge of the pull ring 3 is curled inward to form a rolled edge 34, which extends from the arc opening 311 on one side of the connecting part 31 to the arc opening 311 on the other side.

[0036] Specifically, the rolled edges 321 and 34 of the through hole ensure that the inner edge of the through hole 32 and the outer edge of the pull ring 3 are not too sharp, thus preventing cuts to the hand when it comes into contact with the pull ring 3, improving safety, and increasing the strength of the pull ring 3, making it easier to use.

[0037] Furthermore, the arc 311 that bends inward toward the pull ring 3 determines the folding position of the pull ring 3, making it easy for the pull ring 3 to be quickly folded and attached to the aluminum foil 2.

[0038] like Figure 1 , 2 As shown, the distance between the through hole 32 and the outer wall of the ring cover 1 on the side of the positioning part 33 is greater than the radius of the through hole 32, which limits the position and size of the through hole 32 and avoids the through hole 32 being unsuitable in position and size, which would be detrimental to the use of the pull ring 3.

[0039] The through-hole rolled edge 321 and rolled edge 34 of this utility model ensure that the edges of the pull ring 3 are not too sharp, avoiding cuts to the hands when they come into contact with the pull ring 3, while increasing the strength of the pull ring 3 and making it easier to use.
