Description

Double cap container and double cap having a double blocking structure of inner cap and outer cap

The present invention relates to a double cap container, and more specifically, to a double cap container having a double structure of an inner cap and an outer cap and a double blocking structure of an inner cap and an outer cap, and a double cap.

Tea and other beverages are sold and consumed in beverage containers of a certain shape.

Typically, beverage containers contain drinkable liquid beverages or teas, and the cap is opened to drink them.

However, when taking oral medications such as health supplements or vitamins, they are often consumed with a beverage (in this case, a health supplement drink).

Containers that allow beverages and pills to be consumed simultaneously or together are being developed and marketed.

Patent registration No. 10-1317556, applied for and registered by the applicant, discloses a 'container that allows separate storage of liquid beverages and solid supplements and drinking them together.'

The above registered patent addresses the issue of being able to take beverages and pills simultaneously or together, but there are cases where problems arise with the pills due to moisture from the beverage inside and moisture from the outside penetrating during long-term storage.

In particular, double-capped containers that store beverages and pills at the same time have problems such as moisture from the beverage (liquid) inside seeping into the pills (usually solid ingredients) stored on top, causing the pills to melt, rot, and be damaged.
