Description

Technical Field

[0001] The utility model relates to the technical field related to bottle caps, and in particular to a combined bottle cap. Background Art

[0002] Bottle caps are an important part of food and beverage packaging, and are also the first place where consumers come into contact with products. Bottle caps have the function of keeping the contents of the product sealed, and also have the functions of anti-theft opening and safety. Therefore, they are widely used in bottled products. Therefore, bottle caps are the upstream industries of food, beverage, wine, chemical industry, and pharmaceutical industry, and are key products of bottle container packaging.

[0003] The existing combined bottle cap seals the bottle mouth by threading the internally threaded outer bottle cap with the externally threaded bottle mouth. However, in the process of thread matching, the internally threaded outer bottle cap and the externally threaded bottle mouth are prone to getting stuck when threaded (the thread grooves of the internal and external threads are not correctly staggered and connected, causing the two threads to collide with each other), resulting in a high crooked cap. The outer bottle cap and the bottle mouth are not connected at one time and need to be re-connected, which is more troublesome. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model proposes a combined bottle cap to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The locking mechanism comprises a locking mechanism which is configured to lock the locking cam of the outer bottle cap and the locking cam of the outer bottle cap so that the locking cam is locked.

[0007] Furthermore, in order to make the driving rod slide synchronously with the moving plate, one end of the connecting rod away from the sliding block is hingedly connected to a sliding block, and one end of the sliding block extends into the moving cavity and is fixedly connected to the moving plate.

[0008] Furthermore, in order to make the driving rod slide stably in the driving cavity, a second spring is wound on the outer surface of the driving rod, and two ends of the second spring are fixedly connected to the inner surface of the driving cavity and the sliding block respectively.

[0009] Furthermore, in order to fix the outer bottle cap on the bottle body, a bottle mouth is provided on the top of the bottle body, the bottle mouth is matched with the bottle mouth groove, and a limiting groove is provided on the outer surface of the bottle mouth, and the limiting groove matches the limiting block.

[0010] Furthermore, in order to prevent the limiting block from blocking the movement of the bottle mouth, a placement groove is provided on the inner surface of the bottle mouth groove, and the placement groove matches the limiting block.

[0011] Furthermore, in order to seal the bottle mouth, a bottle plug is fixedly connected to the top center of the bottle mouth groove, and the outer surface of the bottle plug matches the inner surface of the bottle mouth.

[0012] Furthermore, in order to increase the sealing performance between the bottle mouth and the bottle mouth groove, a sealing ring is fixedly connected to one end of the outer surface of the bottle plug close to the top of the bottle mouth groove.

[0013] Beneficial effects of the utility model:

[0014] 1. By pressing the top plate, the movable plate moves synchronously with the top plate, thereby contracting the first spring. The movement of the movable plate drives the slider to slide, and the connecting rod moves in the working chamber. The movement of the connecting rod drives the sliding block to slide, and the driving rod slides into the driving chamber, so that the limit block moves into the placement groove. At this time, the bottle mouth is placed in the bottle mouth groove, and the top plate is released. Under the action of the elasticity of the first spring, the movable plate slides toward the top of the movable cavity, and drives the connecting rod to move, so that the driving rod slides into the bottle mouth groove, and the limit block moves into the limit groove, thereby avoiding the situation that the inner thread outer bottle cap and the outer thread bottle mouth are easily stuck and distorted when the threaded connection is made, so as to achieve the effect that the outer bottle cap and the bottle mouth can be connected at one time.

An annular working chamber 9 is provided on the top of the inner surface of the outer bottle cap 1, and the top of the sliding block 12 extends into the working chamber 9 and is hinged with the connecting rod 11. A sliding groove for sliding the sliding block 12 is provided between the working chamber 9 and the driving chamber 13. A fixed groove 2 is provided on the top of the outer bottle cap 1, and the fixed groove 2 is slidably connected to the top plate 3. A moving rod 4 is fixedly installed on the bottom end of the top plate 3. The end of the moving rod 4 away from the top plate 3 extends into the moving chamber 5 provided in the inner surface of the outer bottle cap 1 and is connected to the moving chamber 5 provided in the inner surface of the outer bottle cap 1. The plate 6 is fixedly connected, a bottom groove 7 is provided on the bottom end of the moving cavity 5, and the bottom end of the bottom groove 7 is connected to the moving plate 6 through a first spring 8.

[0026] Working principle:

[0027] In actual use, if it is necessary to fix the outer bottle cap 1 on the bottle mouth 20, by pressing the top plate 3, the movable plate 6 moves synchronously with the top plate 3, and then the first spring 8 contracts. The movement of the movable plate 6 drives the slider 10 to slide, and the connecting rod 11 moves in the working chamber 9. The movement of the connecting rod 11 drives the sliding block 12 to slide, and the driving rod 14 slides to the end away from the bottle mouth groove 18, so that the limit block 15 moves to the placement groove 17. At this time, the bottle mouth 20 is placed in the bottle mouth groove 18, and the top plate 3 is released. Under the elastic action of the first spring 8, the movable plate 6 slides to the top of the movable chamber 5, and drives the connecting rod 11 to move, so that the driving rod 14 slides to the end close to the bottle mouth groove 18, and the limit block 15 moves to the placement groove 17. The positioning block 15 moves into the limiting groove 21, thereby preventing the internally threaded outer bottle cap and the externally threaded bottle mouth from being easily stuck and causing the high crooked cap when the threaded connection is made, so that the outer bottle cap 1 and the bottle mouth 20 can be docked at one time. If it is necessary to move the outer bottle cap 1 out of the bottle mouth 20, the top plate 3 is pressed, so that the movable plate 6 moves synchronously with the top plate 3, and then the first spring 8 contracts. The movement of the movable plate 6 drives the slider 10 to slide, and the connecting rod 11 moves in the working chamber 9. The movement of the connecting rod 11 drives the sliding block 12 to slide, and the driving rod 14 slides to the end away from the bottle mouth groove 18, so that the limiting block 15 in the limiting groove 21 moves to the placement groove 17, and then the outer bottle cap 1 is moved out of the bottle mouth 20.
