The present invention relates to a PET bottle that can be folded in multiple stages, and more particularly, to a PET bottle that can be folded in multiple stages to minimize volume during folding and to prevent deformation.

In general, bottled water, beverages, alcoholic beverages, liquid foods, etc. are sold or used in various containers. Recently, various types of PET bottles formed of synthetic resin materials such as plastics have been used for reasons of weight reduction and recycling. In particular, large-capacity beverages, bottled water, alcoholic beverages, and the like of 1 liter or more are mostly PET bottles.

Large-capacity PET bottles actually have a cylindrical or other form of trunk that provides the bulk of the bulk, a neck located at the top of the trunk and converging to narrow upwards, and at the top of the neck. It consists of an opening which is actually opened for entry and exit of the contents, and a lid for opening or closing the opening as necessary. Here, the body portion, the neck portion and the opening hole are all formed integrally, and are formed to be contracted or expanded as necessary.

PET bottles formed as described above are mainly sold in large quantities of drinking water and beverages, as well as recently filled with beer.

However, such PET bottles generally have a size of 0.5 liter (L) or 1.5 liter (L), depending on the amount of the contents, and when the contents are poured into a cup, the drink is made through the inlet located at the top.

Therefore, after opening and drinking the necessary amount, the bottle cap is kept closed and the contents are stored in the case of the drink containing the liquid carbon dioxide, and the carbon dioxide is generated, and the carbon dioxide expanded in the empty space is filled in the empty space. The reality is that when the lid is opened for drinking, it is discharged to the outside and loses the intrinsic taste of the soda.

In particular, the beverage in the PET bottle is filled with carbon dioxide condensed inside by the vibration and filled in the empty space, and when the lid is opened and discharged to the outside as if steam is removed, the carbon dioxide is inherently unique when the lid is opened frequently. Will lose the taste.

In addition, in the case of a conventional PET bottle, since the consumer does not have a separate folding part after drinking the beverage, the volume cannot be reduced during the empty bottle recovery, so the worker collects by stepping on the foot or pressed using a separate device, thus reducing empty bottles and recycling resources Low utilization rate caused problems that caused the main cause of destroying nature.

In order to solve this problem, Korean Utility Model Registration No. 0225681 (foldable beverage PET bottle) was developed.
