Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a sealing gasket with an easy-to-pull ring.

Example 1: the utility model provides a take sealing gasket of easy pull ring, combines shown in fig. 1 and fig. 2, includes gasket main part 1, and in this embodiment, gasket main part 1 includes aluminium foil layer 7, PET layer 8 and the heat-seal layer 9 of compound in proper order, and when PET layer 8 and heat-seal layer 9 carry out the complex, PET layer 8 can melt and have viscidity for PET layer 8 bonds on aluminium foil layer 7, and the same reason makes heat-seal layer 9 bond on PET layer 8. Meanwhile, the glue can be coated for compounding, and the glue is food-grade glue.

If necessary, some functional layers may be added to the gasket body 1, but care should be taken to avoid the added functional layers from being too strong and difficult to tear.

The side, opposite to the PET layer 8, of the aluminum foil layer 7 is compounded with the easy-to-pull ring 2 and the fixing ring 5, the fixing ring 5 is compounded on the aluminum foil layer 7 through strong glue, and the outer edge of the fixing ring 5 is flush with the outer edge of the gasket main body 1. The outer ring of the ring-pull ring 2 is connected with the inner ring of the fixing ring 5, the ring-pull ring 2 comprises a ring belt 3 part connected end to end and a hand-pinching bulge 4 part integrally connected with one end of the ring belt 3, and the ring belt 3 is also compounded on an aluminum foil layer 7 through a strong glue.

One end of the ring belt 3 is in an arc shape bending towards the ring and is integrally connected with the hand pinching protrusion 4, namely, when the gasket body 1 is torn, the gasket body 1 is torn by utilizing a shearing force in an arc-shaped track, so that the gasket body 1 is easier to tear.

In this embodiment, the endless belt 3 and the fixing ring 5 are integrally provided, the endless belt 3 and the fixing ring 5 are separated by die cutting operation, the die cutting slits 6 left during die cutting are provided between the fixing ring 5 and the endless belt 3 and between the head and the tail of the endless belt 3, the fixing ring 5 and the endless belt 3 are integrally connected at multiple points, and the head and the tail of the endless belt 3 are integrally connected at multiple points.

Example 2: as shown in fig. 3, the present embodiment is different from embodiment 1 in that an end of the pinch protrusion 4 facing away from the ring belt 3 is tilted to a side facing away from the pad main body 1, and an interval exists between the end of the pinch protrusion 4 facing away from the ring belt 3 and the pad main body 1.

The middle part of the hand-held bulge 4 is also provided with a through hole 10 which is convenient for fingers to pass through to pull the ring belt 3. In order to avoid the fracture when the pinching protrusion 4 and the ring belt 3 are pulled, a reinforcing layer 11 is combined on the pinching protrusion 4 and the ring belt 3, which face away from the gasket main body 1, and in this embodiment, the reinforcing layer 11 is a PE layer.

When the upper reinforcing layer 11 is compounded, the hand-pinching protrusions 4 can naturally tilt by utilizing the characteristic that the PE material of the reinforcing layer 11 shrinks due to heating.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
