Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

An easy-to-open claw-type unscrewing cap, which is widely used for sealing and packaging containers such as cans, includes a cap body 1, as shown in fig. 1, and the cap body 1 is divided into an outer wall surface and an inner wall surface facing the interior of the container. The mouth of the cover body 1 is provided with claws 4 for clamping the mouth of the container, in this embodiment, four claws 4 are arranged at the mouth of the cover body 1 in an annular array, and the claws 4 are arranged in a protruding manner towards the central axis of the cover body 1.

As shown in fig. 1 and 2, a pressing point 3 is provided at the midpoint of the circular cap 1, the pressing point 3 is integrally provided with the outer wall surface of the cap 1, and a hemisphere protruding toward the outer wall surface of the cap 1 is punched at the midpoint of the cap 1 by a punching method.

As shown in fig. 2 and 3, a deformation groove 2 is provided beside the pressing point 3. The deformation groove 2 is positioned on the outer wall surface of the cover body 1, so that the deformation groove 2 is prevented from rusting and polluting the accommodated substance after being contacted with the accommodated substance in the container. The depth of the deformation groove 2 is smaller than the thickness of the cover body 1, and the specific depth of the deformation groove 2 can be set by referring to the material of the cover body 1. For example, if the hardness of the material is high, the depth of the deformation groove 2 may be set to be a little greater than one-half of the thickness of the cover 1 and less than three-quarters of the thickness of the cover 1; if the hardness of the material is low, the depth of the deformation groove 2 can be set to be less than one half of the thickness of the cover body 1 and greater than one quarter of the thickness of the cover body 1.

As shown in fig. 4, the deformation groove 2 is provided with a plurality of segments, which are arranged in an annular array around the pressing point 3 with reference to the pressing point 3. Two adjacent strip-shaped variable grooves 2 are arranged at intervals. All the deformation grooves 2 are located on a circle having a diameter greater than or equal to the diameter of the contact point of the pressing point 3 with the cap 1.

As an alternative embodiment in this embodiment, as shown in fig. 5, the deformation groove 2 is provided in an annular structure, and is disposed around the pressing point 3, i.e., an annular groove is formed. Compared with the previous scheme, the processing of the annular groove is simpler and more convenient, and the diameter of the annular groove in the scheme is larger than or equal to that of the contact part of the pressing point 3 and the cover body 1.

As another alternative embodiment of this embodiment, as shown in fig. 6, only one deformation groove 2 is provided, which is offset from the circular contour of the pressing point 3, that is, the diameter of the arc of the deformation groove 2 is larger than the diameter of the contact between the pressing point 3 and the cap 1. The diameter of the arc where the deformation groove 2 is located in the scheme can also be equal to the diameter of the contact position of the pressing point 3 and the cover body 1. In this embodiment, the deformation groove 2 is semicircular.

In order to make the cover body 1 suitable for packaging more products, the cover body 1 can be made of tinplate or aluminum alloy, and the cover body is usually used for packaging products with higher moisture content in consideration of the characteristic that the aluminum alloy is difficult to rust; tinplate is often used to package nuts and other products with low moisture content.

In the in-service use process, earlier to pressing point 3 application of force, with deformation groove 2 pressure breakage, the low pressure in the container is balanced through cracked deformation groove 2 and external atmospheric pressure for the container is inside and outside atmospheric pressure impartial, when uncapping, need not overcome the suction that the low pressure caused, makes the process of uncapping more laborsaving.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
