Description
Technical Field
The utility model relates to a zip-top can top cap specifically indicates a prevent spouting zip-top can top cap.
Background
With the continuous improvement of the life quality of people, soda water becomes an indispensable part of the life of people. People like the delicious taste of the soda water, and the shadow of the soda water can be seen anytime no matter on a dining table or in leisure time. Soda water also becomes one of the most popular drinks in summer. However, a large amount of carbon dioxide exists in the pop can, and if the pop can filled with the pop can is shaken violently, the pop can spray the carbonated pop can, so that hands, clothes and the like can be stained. It is a problem to be solved how to prevent the soda from being sprayed from the can. The existing pop can top cover has the problems that the drinking is influenced while the steam and water can not be effectively prevented from being sprayed out and prevented from being sprayed out, and the like.
For example, chinese patent publication discloses a blow-out preventer of a can of application No. CN2404819, in which a spacer is provided between a pull ring and an opening piece, and when the pull ring is pulled to open the opening piece of the can, the liquid sprayed out is blocked by the spacer. The utility model discloses a no matter also have whether in the easy open can soda through rocking, all can pull up the spacing block, and when rocking the back open easy open can, because the atmospheric pressure is big in the jar and blockked by the spacing block, only can drink when jar interior atmospheric pressure reduces automatically the problem.
SUMMERY OF THE UTILITY MODEL
The utility model discloses be exactly to prior art not enough, provide a simple structure reasonable, can effectively prevent spouting and do not influence the easy open can top cap of preventing spouting of drinking.
In order to solve the problem, the utility model discloses a prevent spouting easy open can top cap, include top cap body, pull ring and the fan-shaped closure plate that is close to top cap body edge, pull ring point-end and closure plate point-end are articulated, still include montant, confined plastic sheet and spring all around, the montant sets up the position and the one end that are close to the closure plate score line on the top cap body and stretches into jar internal chamber, the plastic sheet passes through montant and this body coupling of top cap, the spring cup joints on the montant, its one end and plastic sheet butt, the other end and top cap body butt.
Furthermore, the montant sets up respectively in the both sides that the top cap body is close to the tip of closing piece and keep away from most advanced both sides, and is close to the most advanced montant length of closing piece and is greater than the most advanced montant length of keeping away from the closing piece. The different lengths of the vertical rods can enable the plastic sheet to be in an inclined state when the plastic sheet is static, so that drinking is not affected.
Further, the spring has a greater length at a position near the tip of the closure panel than at a position away from the tip of the closure panel. The different compression amounts of the springs can ensure that the plastic sheets can not be pressed when the air pressure in the tank is increased, thereby achieving the purpose of not influencing drinking.
Furthermore, the area of the plastic sheet is larger than the area formed by the vertical rods. The plastic sheet has larger area, so that the pull ring opening can be better sealed, and the sealing performance is not influenced.
Has the advantages that:
the utility model has the advantages of simple and reasonable structure, can effectively prevent spouting and do not influence the consumer and drink. The lower end of the top cover body is provided with a plastic sheet which covers the sealing sheet and is sealed at the periphery, so that an opening which appears due to the opening of the sealing sheet can be covered when the steam and water are opened, and liquid sprayed out due to the increase of air pressure is blocked; the vertical rod at the lower end of the top cover body is used for connecting the top cover body, the plastic sheet and the spring, so that the plastic sheet can still be left in the pop can to play a role in blowout prevention when the sealing sheet is opened, the position of the vertical rod is close to the cutting line of the sealing sheet, the area of the plastic sheet is as small as possible while blowout prevention is realized, and the material consumption is reduced; set up the spring aim at that the setting is located between top cap body and the plastic sheet on the montant and make the plastic sheet change and go up and down along with the spring compression volume that the difference of jar internal atmospheric pressure leads to reach and prevent spraying when not influencing the consumer and drink experience, thereby still can leave the space when just the spring compresses completely and can make jar internal atmospheric pressure reduce fast, conveniently drink.

Detailed Description
The invention will be described in further detail with reference to the following figures and specific embodiments:
the top cover of the blowout-preventing pop can comprises a top cover body 1, a pull ring 2, a sealing sheet 3, a vertical rod 4, a plastic sheet 5 and a spring 6. Wherein the tip of the pull ring 2 is hinged with the tip of a sector-shaped sealing sheet 3 consisting of a cutting line, and the sealing sheet 3 is close to the edge part of the top cover body. Montant 4 sets up the position and the one end that are close to 3 scorelines of closing piece on top cap body 1 and stretches into jar internal chamber, plastic sheet 5 is connected with top cap body 1 through montant 4, spring 6 cup joints on montant 4, its one end and 5 butts of plastic sheet, the other end and 4 butts of top cap body.
Referring to the attached drawings, a pull ring 2 is hinged to a sector-shaped sealing sheet 3 consisting of a cutting line and is positioned at the edge part close to a top cover body 1, vertical rods 4 at the lower end of the top cover body 1 are respectively positioned at two sides close to the tip end of the cutting line of the sealing sheet 3 and two sides far away from the tip end of the sealing sheet 3, and preferably, the vertical rods 4 are 4 sleeves, and are provided with springs 6, and the lower ends of the vertical rods are provided with convex vertical rods, so that plastic sheets 5 can not be separated from the. The plastic sheet 5 is positioned on the vertical rod 4 and is separated from the top cover body 1 through the spring 6, preferably, the density of the plastic sheet 5 is smaller than that of steam water, the shape of the plastic sheet is similar to that of the sealing sheet 3, and the area of the plastic sheet is larger than that enclosed by the vertical rod 4. The length of the spring 6 on the vertical rod 4 close to the tip of the sealing piece 3 is larger than that on the vertical rod far away from the tip of the sealing piece 3, so that the plastic sheet 5 is in an inclined state when the air pressure in the tank is normal.
When the air pressure in the tank is stable, the plastic sheet is suspended because the density is smaller than that of soda water, the spring in the state is not compressed, the plastic sheet is in an inclined state because of the different lengths of the spring, and the closing piece is opened at the moment, so that the plastic sheet does not influence drinking. When the pop can is violently shaken and the air pressure in the can is increased, the sealing sheet is opened, the plastic sheet is jacked up by the air pressure because the plastic sheet covers the sealing sheet, the spring is compressed at the moment to play a role in blowout prevention, and at the moment, because the pop can is not completely sealed by the plastic sheet, fine gaps can be reserved for air to leak out to reduce the air pressure in the can. After the internal air pressure of the pop can is reduced, the plastic sheet is slowly bounced off under the action of the elastic force of the spring, the sealed pull ring opening is opened, and the steam pressure is far less than the internal air pressure of the shaken steam can, so that the spring cannot be completely compressed, a sufficient gap can be reserved to enable the steam to flow out, and therefore the drinking of the steam is not affected.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
