Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The embodiment is as follows:
as shown in fig. 1 and 2, the easy-to-open lid for cubilose can of the utility model comprises a lid body 1 and a slidable piston 2, wherein the lid body 1 comprises a top cover 11 and a side edge 12 extending downwards from the edge of the top cover 11, and the inner ring of the side edge 12 is provided with an internal thread 13 for performing spiral type sealing joint with the external thread at the opening of a container 3.
The top cover 11 is formed with a vertical through hole 14, and the through hole 14 is preferably located at the middle of the top cover 11.
The slidable piston 2 comprises an upper plug body 21, a lower plug body 22 and a middle connecting column 23 connected between the upper plug body and the lower plug body, wherein the middle connecting column 23 penetrates through the through hole 14 and is in contact sealing with the through hole 14.
The intermediate connecting post 23 is able to slide up and down within the via 14. Meanwhile, a concave portion 24 is arranged on the outer cylindrical surface of the middle connecting column 23, the distance between one end of the concave portion 24 close to the upper plug body 21 and the lower plug body 22 is greater than the depth of the through hole 14, and the distance between one end of the concave portion 24 close to the lower plug body 22 and the upper plug body 21 is greater than the depth of the through hole 14, so that the concave portion 24 can bring external air into the container 3 through downward sliding.
Further, the top surfaces of the upper and lower plugs 22 and the bottom surface of the top cap 11 can be in sealing fit. Moreover, the upper plug body 21 and the lower plug body 22 may be solid bodies with flat sheet or circular shapes, or other shapes or shapes that facilitate pressing.
Meanwhile, the slidable piston 2 may be made of rubber, or may be made of rigid material such as plastic, tinplate, aluminum sheet, etc.
The working principle of the utility model is as follows:
when the can is hot filled and sealed, the air in the top gap of the glass bottle is exhausted, and the slidable piston 2 is pushed upwards, so that the top surface of the lower plug body 22 is in sealing fit with the bottom surface of the top cover 11, and the state is shown in fig. 3.
When the cap is to be opened, the slidable piston 2 is pressed downwards slightly, as shown in fig. 4, so that the bottom surface of the upper plug body 21 is attached to the top surface of the top cover 11, the concave part 24 on the middle connecting column 23 brings external air into the bottle, the vacuum state of the can is broken, and the cap can be easily unscrewed due to balance of air pressure inside and outside the bottle.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
