Description

  The present invention relates to a container with an overcap having an opening blade, and it is intended to reliably avoid contact and scattering between fingers and contents at the time of opening the container and improve operability. is there.

  In recent years, aseptic beverage filling systems have been adopted for beverages such as coffee and tea in order to maintain the taste and flavor of the contents well. In general, a film-like sealing sheet is affixed to the film and an overcap is attached to the outer side to protect the sealing sheet.

  This type of container is provided with a straw on the body of the container, and the straw is inserted through a hole formed in the overcap, and the content in the container is sucked by breaking through the sealing sheet at the tip of the straw. I am doing so.

  In addition, recently, since the contents are heated by the warmer, it is difficult to use a straw, and the sealing sheet is opened with a single touch using the pressing piece of the overcap, and the overcap is formed. There has also been proposed a container of a type for drinking contents directly from a drinking mouth (see, for example, Patent Document 1).

By the way, with a container that opens the sealing sheet with a single touch, the contents may be scattered depending on the force applied when operating the push-down piece, and the push-down piece touched by the fingertip may be immersed in the content. In addition, the fingertips may touch the contents, which is not preferable in terms of hygiene, and a solution has been demanded.
