Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottles, in particular to an improved bottle mouth of a PCO bottle and a bottle with the bottle mouth. Background Art

[0002] PCO bottle mouth is a bottle mouth specification widely used in food, beverage and other industries. It has the characteristics of environmental protection, durability, lightness, standardized design and high sealing. It is specially designed for use with plastic bottle caps and is one of the most widely used beverage bottle mouth specifications on the market.

[0003] In the existing patents, a Chinese utility model patent with reference patent publication number CN204056499U discloses an improved PCO bottle mouth and a bottle mouth having the same. The thread bottom diameter of the improved PCO bottle mouth in the patent is 5.5%-6.5% larger than that of the standard PCO bottle mouth. However, for some PCO bottle mouths, such as the 2622 bottle mouth, due to the limitation of the bottle cap structure, the corresponding technical effect cannot be achieved by implementing the patent.

[0004] Therefore, the utility model supplements the bottle mouth of the PCO bottle improved by the existing patent. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides an improved bottle mouth of a PCO bottle and a bottle with the bottle mouth.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] An improved bottle mouth of a PCO bottle, wherein the thread bottom diameter of the improved PCO bottle mouth is increased by 0.2-2.7% compared with the thread bottom diameter of the conventional PCO bottle mouth.

[0008] Furthermore, the thread bottom diameter of the conventional PCO bottle mouth is 24.2 mm, and the thread bottom diameter of the improved PCO bottle mouth is 24.25-24.85 mm.

[0009] Furthermore, the diameter d' and height h' of the area between the thread bottom and the top surface of the bottle mouth of the improved PCO bottle are the same as the diameter d and height h of the area between the thread bottom and the top surface of the bottle mouth of the conventional PCO bottle.

[0010] Furthermore, a reinforcing layer is applied to the outer side of the thread bottom of the bottle mouth of the conventional PCO bottle, thereby obtaining the thread bottom of the bottle mouth of the improved PCO bottle, and the reinforcing layer is applied in ways including but not limited to spraying, coating and welding.

[0011] The utility model also provides a PCO bottle, which has the above-mentioned improved bottle mouth of the PCO bottle and a bottle cap connected to the bottle mouth of the improved PCO bottle, wherein the bottle cap is preferably a 2622 bottle cap.

[0012] Furthermore, when the thread top diameter of the bottle cap is 24.45 mm, the thread bottom diameter of the bottle mouth of the improved PCO bottle is 24.25-24.45 mm, which is increased by 0.2-1%.

[0013] Furthermore, when the thread top diameter of the bottle cap is 24.45 mm, the thread bottom diameter of the bottle mouth of the improved PCO bottle is 24.35 mm, which is increased by 0.6%.

[0014] Furthermore, when the thread top diameter of the bottle cap is 24.80 mm, the thread bottom diameter of the bottle mouth of the improved PCO bottle is 24.25-24.80 mm, which is increased by 0.2-2.5%.

[0015] Furthermore, when the thread top diameter of the bottle cap is 24.85 mm, the thread bottom diameter of the bottle mouth of the improved PCO bottle is 24.25-24.85 mm, which is increased by 0.2-2.7%.

[0016] In the utility model, when the thread top diameter of the bottle cap is 24.80 mm or 24.85 mm, the thread bottom diameter of the bottle mouth of the improved PCO bottle is 24.70 mm, which is increased by 2.1%.

[0017] The utility model has the following advantages and beneficial effects:

[0018] By increasing the bottom diameter of the bottle mouth thread, the sealing formed by the matching connection between the bottle mouth and the existing bottle cap is improved. The improvement of the bottle mouth structure can almost completely utilize the original bottle blank production equipment, and there is no need to design and develop a bottle cap corresponding to the bottle mouth, and will not affect the blow molding process of the bottle blank with the improved bottle mouth; the weight of the bottle with the improved bottle mouth is almost unchanged as a whole, and a better sealing effect can be achieved by using the existing bottle cap without almost increasing the cost.
