Description

Technical Field

[0001] The invention relates to the technical field of bottle mouth structures, in particular to a plunger-type hard-sealed bottle mouth structure. Background Art

[0002] The existing bottle body design is generally a smooth cylindrical shape, some with a bottleneck, some without a bottleneck, and the bottle body is directly connected to the bottle mouth; but each bottle mouth is directly connected to the bottle cap, which has threads on the bottle mouth and only threads on the inner wall of the bottle cap, and the two are connected.

[0003] Referring to Chinese patent publication number CN204737103U, a glass wine bottle with a double-connected structure of an inner bottle cap and an outer bottle cap is provided. By adopting the double-connected structure, the structure is simple and can be significantly distinguished from existing ordinary wine bottles through the design of the double-connected structure to prevent counterfeiting. In addition, the newly added outer bottle cap of the double-connected structure wine bottle can greatly improve the decorative effect of the wine bottle.

[0004] Referring to a container bottle and its bottle mouth connection structure with Chinese patent publication number CN211282097U, a protrusion is inserted into a groove, and the protrusion can be stuck in the groove to lock the bottle cap, prevent the connection between the bottle cap and the bottle mouth from becoming loose, and ensure the sealing.

[0005] A comprehensive analysis of the above reference patents shows that the existing bottle mouth sealing structure cannot be applied to hard seals between some ceramic or glass materials, and the sealing effect is poor. For example, the reference patent CN204737103U, a glass wine bottle with a double connection structure of an inner bottle cap and an outer bottle cap, only innovates in terms of connection firmness, but does not improve the sealing effect of the bottle mouth connection, and cannot be applied to sealing between hard materials. At the same time, the reference patent CN204737103U, a glass wine bottle with a double connection structure of an inner bottle cap and an outer bottle cap, and CN211282097U, a container bottle and its bottle mouth connection structure, use connection structures that vary in thread thickness, which will bring different effects. The threads used in the two reference patents are medium-coarse or fine, which are more suitable for soft materials. The threads are small without falling off due to the elasticity of the plastic, which is conducive to injection molding and locking.

[0006] The present invention is a multi-headed, broken-end trapezoidal wire thread, which is not a wire in sections as in the reference patent, but a wire without a pointed end. Since "hard sealing" uses ceramics or glass as accessories instead of plastic, the materials are harder than metals and have characteristics such as being fragile, inelastic, and brittle. The use of multi-head wire can play a good role in smoothing the wire when starting to frequently switch, and the bottom of the tooth is flat, and the top of the tooth is also flat. Glass products may have a trapezoidal angle of the top of the tooth with a slight arc shape during the production process due to the characteristics and process of the glass. This type of wire thread switches quickly and has a small rotation angle, which is suitable for cup lids, bottle caps, etc. What is locked is a lid made of "hard sealing" hard materials such as ceramics and glass.

[0007] At the same time, due to the curvature of the beak of the bottle mouth and the guide plate at the upper end of the bottle inner cover, the present invention uses the tension of water to control the flow direction of the liquid. When the flow to the front end stops, the last drop of liquid will flow back into the bottle. Therefore, the bottle mouth structure of the present invention can effectively prevent the liquid from overflowing when the bottle is tipped, and prevent the liquid in the bottle from being contaminated by the external environment, which is environmentally friendly and safe.

[0022] (3) Beneficial effects

[0023] The present invention provides a plunger-type hard-sealed bottle mouth structure. Compared with the prior art, it has the following advantages:

[0024] (1) The plunger-type hard-sealed bottle mouth structure is fixedly installed with a sealing circular plate on the top of the inner cover body, and a groove is opened on one side of the inner cover body, a guide block is fixedly installed on the bottom of the inner cover body, and a fastening protrusion adapted to the sealing circular plate is fixedly installed on the top of the inner wall of the outer cover body, and the inner wall of the outer cover body may have a first thread. The present invention is a multi-headed broken-end trapezoidal thread, which is not a thread of section by section as in the reference patent, but a thread without a pointed end. Since "hard sealing" uses ceramic or glass as accessories instead of plastic as accessories, its material is harder than metal and has the characteristics of being fragile, inelastic, brittle, etc., the selection of multi-head thread can play a good role in smoothing the thread when starting to frequently switch. The bottom of the thread is flat and the top of the thread is also flat. Glass products may have a trapezoidal angle of the top of the thread in the production process due to the characteristics and process of the glass, and will have a little arc shape. This thread switches quickly and has a small rotation angle, which is suitable for cup lids, bottle lids, etc. The locked part is a lid made of "hard sealing" ceramic, glass and other hard materials.

Due to the curvature of the eagle beak of the bottle mouth and the guide plate at the upper end of the bottle inner cover, the tension of water is used to control the flow direction of the liquid, and the last drop of liquid when the flow stops at the front end will flow back into the bottle. Therefore, the bottle mouth structure of the present invention can well prevent liquid from overflowing when the bottle body is tipped, and prevent the liquid in the bottle from being contaminated by the external environment, which is environmentally friendly and safe.

The outer surface of the second protrusion 23 is engraved with the same pattern as the first protrusion. A second thread 26 is adapted to the first thread 8, and a liquid groove 27 is provided on the inner wall of the through hole 24. A downward inclined locking groove 28 adapted to the guide block 6 is provided on the inner wall of the through hole 24 and is located below the liquid groove 27, and the locking groove 28 is communicated with the liquid groove 27. The first thread 8 and the second thread 26 both adopt multi-head broken-end trapezoidal thread teeth, and the eagle mouth 25 is designed with an outward eagle mouth at its top to prevent liquid from overflowing, so that the last drop of liquid can flow back from the inside of the eagle mouth 25.

[0040] Example 2

[0041] A plunger-type hard-sealed bottle mouth structure includes a bottle mouth assembly 2 fixedly mounted on the bottle mouth, an inner cover body 1 adapted to the bottle mouth assembly 2, and an outer cover body 3 adapted to the bottle mouth assembly 2. A sealing circular plate 4 is fixedly mounted on the top of the inner cover body 1. Grooves 5 are provided on both sides of the inner cover body 1, and the angle between the two grooves 5 is 180°. A guide block 6 is fixedly mounted on the bottom of the inner cover body 1. A fastening protrusion 7 adapted to the sealing circular plate 4 is fixedly mounted on the top of the inner wall of the outer cover body 3, and the inner wall of the outer cover body 3 may have a first thread 8.

[0042] The bottle mouth assembly 2 includes a circular plate 21 fixedly connected to the bottle mouth, a first protrusion 22 fixedly mounted on the top of the circular plate 21, and a second protrusion 23 fixedly mounted on the bottom of the circular plate 21. The second protrusion 23 extends to the inside of the bottle mouth, and the tops of the first protrusion 22, the circular plate 21, and the second protrusion 23 are all provided with a through hole 24 adapted to the inner cover body 1. An eagle mouth 25 is fixedly mounted on the top of the first protrusion 22, and the inner cavity of the eagle mouth 25 is communicated with the through hole 24. The outer surface of the second protrusion 23 is engraved with a second thread 26 adapted to the first thread 8, and a liquid groove 27 is provided on the inner wall of the through hole 24. A downward-slanted locking groove 28 adapted to the guide block 6 is provided on the inner wall of the through hole 24 and located below the liquid groove 27. The groove 28 is connected to the liquid-passing groove 27. After the outer cover body 3 and the bottle mouth assembly 2 are tightened, the fastening protrusion 7 will tightly press against the top of the sealing circular plate 4, so that the outer surface of the inner cover body 1 is in close contact with the inner wall of the through hole 24 for hard sealing. When the actual manufacturer requires a metal cover, it is better to use a cover made of cold-rolled various metal plates, taking advantage of the characteristics of the metal itself, so that it is better to have a little elasticity, so that it will not fall off or leak. The sealing circular plate 4 and the inner cover body 1 are fixed at a position where an arc-shaped guide groove 10 is adapted to the eagle's mouth 25, and the guide block 6 is slidably matched with the locking bevel 28 to ensure that the inner cover body 1 does not fall off. When the guide block 6 and the inclined surface of the locking bevel 28 reach the highest point, the liquid-passing groove 27 and the groove 5 are aligned with each other, so that the liquid in the bottle can be poured out from the bottle mouth.

[0043] When pouring liquid, it is only necessary to rotate the outer cover body 3 in the opposite direction to separate the first thread 8 and the second thread 26, open the outer cover body 3, and then rotate the sealing circular plate 4 so that the sealing circular plate 4 drives the guide card block 6 to slide and rotate in the opposite direction along the locking inclined groove 28 through the inner cover body 1. At this time, the guide card block 6 will slide and rise along the locking inclined groove 28. When it rises to the highest point of the locking inclined groove 28, the liquid groove 27 is aligned with the groove 5, and the pouring of the liquid can be achieved. When pouring, the liquid will flow out through the through hole 24, the eagle mouth 25 and the arc-shaped guide groove 10 in turn, and the poured liquid will not overflow due to the design of the eagle mouth 25. When it is not tilted, the liquid will automatically flow back to the bottle mouth.

[0044] When the bottle mouth needs to be sealed, it is only necessary to rotate the sealing circular plate 4 in the forward direction to make the guide block 6 rotate along the locking inclined groove 28, and at this time the liquid groove 27 and the groove 5 are offset from each other, and then the outer cover 3 is tightened on the bottle mouth assembly 2. At this time, the fastening protrusion 7 will tightly press against the sealing circular plate 4, so that the entire bottle mouth structure is tightly sealed.

[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art. During the processing of the bottle mouth structure of the present invention, micron-level precision grinding equipment is required for processing.
