EASY OPEN LEVER LEVER FOR BOTTLE

The technical field to which the utility model relates.

This utility model relates to an easily open lever-type lid for a bottle, such as vessels for beer, carbonated drinks, pressurized drinks or drugs.

State of the art

The easy-open bottle cap, available on the market today, is designed so that an exhaust ring is added to the regular cap. The exhaust ring is fixedly connected directly to the body of the lid with a rivet, and two invisible cuts forming an angle of about 20-70 ° are made on the rear side of the body of the lid. In use, the exhaust ring is pulled up to remove the part between two invisible cuts on the body of the cap from the bottle cap, and then open the bottle.

However, the above kind of cover has some disadvantages, indicated below:

1. Since the exhaust ring and the body of the lid are directly fixedly connected by means of a rivet passing through them, the sealing effect of the lid is adversely affected by any weakening of the parts of the rivet relative to the exhaust ring and the body of the lid, and the contents inside the bottle may be contaminated, which leads to danger for health. In addition, the use of a separate rivet for fastening the exhaust ring and the body of the lid makes the manufacturing process more difficult.

2. According to the prior art, the angle between two invisible cuts formed on the back side of the body of the lid is approximately 20-70 °. This relatively large angle not only makes it difficult to open the bottle (a pulling force of about 8 kg is necessary), but also tends to eject a jet of pressurized contents (such as beer, carbonated drinks).

3. According to the prior art, the tail parts of two invisible cuts extend directly to the edge of the body of the lid, which increases the force necessary to separate the exhaust ring from the body of the lid at the tail parts. This increased force can separate the exhaust ring from the body of the lid, or in other words, can make it impossible to smoothly disengage the lid from the bottle, which negatively affects the opening action. This design is not recyclable. In addition, a sharp edge forms at the point where the exhaust ring disengages from the body of the lid, and therefore users or people using the bottle may be damaged.

4. According to the prior art, since the lid body is not provided with a positioning structure for the exhaust ring thereon, the exhaust ring can rotate and / or the exhaust rings can overlap each other during filling, which leads to interference during the filling process.

5. According to the prior art, the upper surface of the lid body is flat, and the part connecting the exhaust ring to the lid body also has a flat structure, therefore, the lid body and the exhaust ring cannot be connected tightly.

6. According to the prior art, the exhaust ring protrudes from the upper surface of the body of the lid, and the overall height of the lid increases. Therefore, the bottling process requires the use of a special device, or the existing bottling device can be used only after the correct modification. Since the conventional easy-open lever-type cover, as mentioned above, cannot be used in existing filling devices, it does not provide compatibility and versatility.

Given the above drawbacks, the inventor, based on extensive experience in design and development in the relevant industries, offers a new easy-to-open lever-type cap for a bottle that has a simple structure, is easy to open, and has high compatibility and excellent versatility.

The purpose of this utility model is to create a new easily open lever-type cap for a bottle that has a simple structure, is convenient to manufacture, and is easy to open. The easy-open lever-type cap can provide hygienic and reliable storage of contents inside the bottle. In addition, compared with a conventional cover, less force is required to open the cover.

Another purpose of this utility model is to create an easily open lever-type cap for a bottle that does not eject the jet while opening the bottle.

An additional goal of this utility model is to create an easily openable lever-type cap for a bottle that requires reduced pulling force, ensures that the body of the cap and the exhaust ring as a whole after opening the cap, smoothly separates the cap from the bottle to prevent damage to the neck of the bottle, which facilitates the processing of an empty bottles and caps and environmental protection. At the same time, an acute angle is not formed in the separation part of the exhaust ring from the body of the lid, which eliminates the risk of injury to the user.

Another purpose of this utility model is to create an easily open lever-type cap for a bottle that prevents the exhaust ring from turning or overlapping during filling so that the filling operation can be performed without interference.

Another purpose of this utility model is to create an easily open lever-type cap for a bottle that has good compatibility and versatility, so that conventional dispensing devices can be used.

According to a utility model, the above objectives are achieved by using an easily open lever-type cap for a bottle that includes a body of a crown cap and an exhaust ring.

A bulge is formed in the center of the inner side of the upper body of the crown cover by extruding upward. An arc-shaped incision surrounding the bulge is made on the inner side of the upper part of the body of the crown cover, and each of both ends of the arc-shaped notch passes to one side of the body of the crown cover with a transition to a straight invisible cut, which allows you to remove the cover from the bottle. The exhaust ring is made integrally with the lever eye in the direction of its central part, while the lever eye is provided with a rivet hole at its free end, which is mounted on the bulge, and the exhaust ring is connected with a riveted connection to the body of the crown cover by convexity. Two concave, arc-shaped grooves corresponding to each other, respectively, are made on both sides of the connecting part between the lever eye and the exhaust ring.

In one preferred embodiment, two direct invisible cuts form an angle of 1-20 ° between them.

In one preferred embodiment, one of the direct invisible cuts extends to the edge of the body of the lid with the formation at the edge of two arcs in the form of a double R with a radius of 0.5-3 mm. The tail of another direct invisible notch is connected to an arcuate invisible notch, which has a radius of 1-5 mm and is located at a distance from the edge of the body of the lid. In one preferred embodiment, the arcuate invisible notch has a radius of 3 mm.

In another preferred embodiment, there are two positioning protrusions corresponding to two straight invisible notches, on the outer side of the upper body of the lid on the side opposite to the two direct invisible notches, and the lower surface of the lever eye is in contact with and positioned protrusions.

In one preferred embodiment, a groove in which the exhaust ring can be accommodated is formed concave downward on the upper body of the lid.

In one preferred embodiment, a circular groove that surrounds the bulge and lends strength to the lid body is further provided within the groove.

In one preferred embodiment, the inner and outer circumferences of the exhaust ring are formed, respectively, in the form of corresponding folded edges in the direction of the lower surface of the exhaust ring, which are snug against each other at the lower surface of the exhaust ring.

In one preferred embodiment, the two sides of the tab eye are, respectively, in the form of corresponding folded edges in the direction of its lower surface.

In one preferred embodiment, a recess which abuts against the body of the lid is formed at the free end of the lever eye, on which a rivet hole is provided.

As indicated above, in the easy-open lever-type cap for a bottle, according to a utility model, the exhaust ring is not directly connected to the cap; instead, it is attached to the center of the body of the lid with a lever eye. The pulling force required to open the cover with the lever eye is significantly reduced due to the so-called lever principle. Since the concave arc grooves are located at the connecting part between the lever eye and the exhaust ring, a lever pivot point is simply and quickly formed while opening the lid, so that the lever eye can act effectively to reduce the required pulling force. In addition, according to the utility model, a separate rivet is not used for the rivet connection, nor is a hole provided for the rivet in the body of the lid; and the lid body and the exhaust ring are connected to each other by convexity. Thus, this system prevents contamination of the contents of the bottle inside the bottle, which could be due to the weakening and therefore inferior state of the seal. This ensures the safety and hygiene of the contents.

Description of Embodiments

As shown in FIG. 1, 2 and 3A, the easy-open lever-type cap for the bottle contains the crown cover body 1 and the exhaust ring 2. A bulge 11 (shown in FIG. 4) is formed in the center of the inner side on the upper part of the cap body 1 by extruding upwards and around the bulge 11 an incision 12 is formed in the form of an arc on the upper part of the body 1 of the crown cover on its inner side, while both ends of the arc notch 12 respectively extend to one side of the body 1 of the crown cover with the transition into two invisible straight cuts 13 that allow you to remove lid from the vessel. The exhaust ring 2 is made in the form of a single unit with the lever eye 21 in the direction of its Central part. The lever eye 21 is provided with a rivet hole 211 at its free end, which is mounted on the bulge 11. The exhaust ring is connected to the body 1 of the crown cover by the bulge 11. Two concave arcuate grooves 212 corresponding to each other are formed, respectively, on both sides of the connecting parts between the lever eye 21 and the exhaust ring 2.

As indicated above, in an easily openable lever-type cap for a bottle, according to a utility model, the exhaust ring is not directly connected to the body of the cap; instead, it is riveted at the center of the body of the lid through a lever eye. The pulling force, which is necessary to open the cover through the lever eye, is significantly reduced due to the so-called lever principle. Since there are concave arcuate grooves at the connecting part between the lever eye and the exhaust ring, a point of support of the lever is formed quickly and easily during opening of the lid, so that the lever eye can act effectively to reduce the required pulling force. In addition, according to a utility model, a separate rivet is not used for a rivet joint, and there is no hole for a rivet in the body of the lid; and the lid body and the exhaust ring are riveted to each other by a bulge which is part of the lid body. Thus, this system prevents contamination of the contents of the bottle inside the bottle, which could otherwise be caused by a weakening and therefore defective sealing condition. This ensures the safety and hygiene of the contents.

Furthermore, according to a utility model, as shown in FIG. 1 and 2, the angle between two straight invisible notches 13 is between 1 and 20 °. If this angle is too large (more than 20 °, for example, in the range from 20 to 70 °, as is customary in the art), a lot of force is required to open the bottle, and it is also possible that a jet of pressurized contents (such as beer) , carbonated drinks, etc.) when opening the bottle, which poses a danger to the user. Based on numerous tests, the angle between two straight invisible cuts 13 is chosen equal to 1-20 °, which leads to the required pulling force of only about 2 kg and ensures smooth separation of the lid from the bottle after opening. In one embodiment, the angle between two straight, invisible notches 13 is 9 °.

According to this embodiment, as shown in FIG. 1 and 2, one of the direct invisible notches 13 extends to the edge of the lid body 1 with the formation of two arcs in the form of a double R with a radius of 0.5-3 mm at the edge of the lid, so that a sharp edge does not form after separation of the exhaust ring from the lid body and This ensures safety for the user. The tail portion of another direct invisible notch 13 extends continuously to an arc-shaped invisible notch 14. The arc-shaped invisible notch 14 has a radius of 1-5 mm and is located at a distance D from the edge of the lid body. According to a utility model, an invisible arc notch 14 and a straight invisible notch 13 constitute a full opening arc, so that a dead angle is not formed during opening, and the lid body 1 is smoothly separated from the bottle when the exhaust ring 2 is pulled over the edge of the lid body 1. Since there is a distance D between the arcuate invisible notch 14 and the edge of the lid body, the lid body 1 and the exhaust ring 2 are ensured as a whole after opening the lid body 1, which facilitates the processing of the lid and further eliminates contamination. In this embodiment, the arcuate invisible notch 14 preferably has a radius of 3 mm.

According to this utility model, both the arcuate invisible notch 14 and the straight invisible notch 13 are located on the back side of the lid body 1, and both are coated with a sheath of polyvinyl chloride or polyethylene (not shown in the figures). Due to this arrangement, an aesthetic appearance of the lid on its outer side is ensured, the required pulling force is minimized, and the effect of the atmosphere on the cuts and thereby their corrosion is prevented, as is the case in the prior art. Thus, the utility model provides the best quality of the contents of the bottle.

As shown in FIG. 2, according to a utility model, two positioning protrusions 15 are provided in accordance with two notches 13 on the outer side of the upper part of the lid body 1 on the side opposite to the notches 13. The lower surface of the tab eye 21 is in contact with the positioning tabs 15, and the tab eye 21 is positioned by means of positioning protrusions 15, so that the exhaust ring 2 is more stable when riveted to the body of the lid 1 and is protected against rotation, and the rotation of the body of the lid 1 relative to the exhaust is further prevented th ring 2 during bottling.

As shown in FIG. 1, 2 and 4, according to a utility model, a concave groove 16 is formed on the upper part of the lid body 1, in which the exhaust ring 2 and the lever eye 21 are completely located. This ensures that the exhaust rings 2 do not overlap each other during filling and thereby allows pass the lid without interference through the filling device. At the same time, due to the fact that the exhaust ring 2 is recessed in the groove 16, the full height of the body 1 of the lid meets the requirements of modern filling lines. Therefore, it is possible to use an existing filling device without any modifications for an easily openable lever-type cap for a bottle, according to a utility model. In other words, the easy-open lever-type cap for the bottle, according to the utility model, has good compatibility and versatility. Furthermore, as shown in FIG. 5, when the drink is poured into the bottle and the lid body 1 is pressed to cover the neck of the bottle, the groove 16 disappears, i.e. becomes flush with the upper surface of the body of the cap, due to the pressure inside the bottle, so that the exhaust ring 2 rises to protrude beyond the upper surface of the body 1 of the cap, which facilitates the user pulling up the exhaust ring 2.

As shown in FIG. 1, 2 and 4, according to a utility model, a circular groove 17 is further provided inside the groove 16, which surrounds the bulge 11. The circular groove 17 gives strength to the lid body 1, so that the lid body 1 satisfies the pressure resistance requirements.

As shown in FIG. 3A, 3B, 3C and 4, according to a utility model, a recess 213 is formed on the free end 211 of the lever eye 21, on which a rivet hole 211 is provided, which abuts against the lid body 1. The recess 213 imparts greater density to the riveted connection between the lid body 1 and the lever eye 21 of the exhaust ring 2 when the lid body 1 is riveted to the exhaust ring 2. Thus, alignment of the exhaust ring 2 with respect to the lid body 1 does not adversely affect the opening of the lid.

As shown in FIG. 3A, 3B, 3C and 4, the inner and outer circumferences of the exhaust ring 2 are, respectively, in the form of corresponding folded edges 22 and 23 in the direction of the lower side of the exhaust ring 2, which are snug against each other on the lower side of the exhaust ring 2. This arrangement provides the ability to integrate the body 1 and the exhaust ring 2, gives an aesthetic appearance to the lid, makes the filling process even, provides a good feeling while pulling the lid up and eliminates possible injury or cuts by burrs. At the same time, since the folded edges 22 and 23 of the inner and outer circles abut against the lower side of the exhaust ring 2, the liquid substance cannot flow into the ring, which prevents its corrosion.

Furthermore, as shown in FIG. 3B, the two sides of the eyelet 21 are respectively formed in the direction of its lower side in the form of corresponding folded edges 214. This increases the strength of the eyelet 21, and thus, during the opening process, there is no need to increase the pulling force due to the strength of the lever eyelet 21, which otherwise may be relatively small.

Although the description of the utility model is based on specific embodiments, these embodiments are not restrictive. Equivalent alternative solutions, variations and modifications can be made by experts in the art without departing from the idea and scope of the utility model.
