Profile design of plastic beverage bottles

Author: mgg-Plastic bottle manufacturer

The shape of the plastic beverage bottle will be designed in the upper, middle and bottom. The upper portion of the bottle is similar to the circular shape, the bottle mouth is a threaded cylindrical; the middle of the cylindrical bottle will increase the shape of the stripes arranged in the shape, except to increase the beauty of the bottle, but also increase the strength of the bottle; bottle body The bottom is generally designed to be concave, and is similar to a dome-shaped petal structure, and the main consideration points of these designs are to increase the end of the bottle. The stress point of the plastic bottle in a pressure-sensitive state will transmit the force to adjacent regions, and the outer force is dispersed along the body surface of the bottle, so that each portion of the arched is partially shared.

The dome shape of the upper portion of the plastic beverage bottle can be seen as a plurality of arched combinations, and can carry external pressure while not producing outward. The middle of the bottle is the thinnest portion, which is easy to depress when it is affected. In order to increase the compressive capacity of the central part, various uneven stripes can be added to the surface of the bottle without increasing the wall thickness.

The bottom of the bottle not only supports the support, but also needs to be in contact with the outer substance, hit and friction, and higher requirements for strength. Some carbonated drinks contain a large amount of gas, there is a certain pressure in the packaging bottle, which uses a concave design to keep the packaging bottle stabilize vertical stand-up state, or effectively reduce the risks of the bottle. At the same time, it can also impart its intensity of anti-internal pressure and water pressure impact to prevent breakage of the bottle. In theory, the most cracking structure is a round bottle design, but it needs to be matched with a base that allows the bottle to stand up standing.

There is no additional base in the bottom of the petals, and the multi-point support guarantees the stability of the packaging bottle.
