Field of the Invention The present invention relates to a tube container with a check valve for preventing backflow of the contents and air after the contents have been extruded, and more specifically, it is provided in the mouth of a tube container having a restoring property. The check valve has a valve member that is attached to and detached from a valve seat provided at the mouth of the check valve, and a locking member that locks the valve member at the inner diameter step of the tube container to prevent the valve member from coming off. A tube container with a check valve provided.

Description of the Related Art Conventionally, a tube container whose content is a substance that deteriorates when exposed to air has excellent gas barrier properties, and after extruding the content, the shape of the tube container is maintained as it is (plastic deformation does not occur). Metals such as aluminum, tin, and lead have been often used because they do not suck outside air into the tube container. However, the metal tube container described above may not be usable due to corrosion or the like depending on the property of the contents, and in addition, from the viewpoint of disposal after use and cost, it is mainly a multi-layered laminate such as an olefin film. It is replacing the use of body-made plastic tube containers.

れ変色させてしまうという懸念もある。However, although this plastic tube container is excellent in terms of corrosion resistance, disposal and cost, it is not plastically deformed after the content is extruded, and its restoring force causes an air bag. That is, there is a property that air corresponding to the amount of the pushed contents is drawn into the inside of the container. Such a characteristic of the plastic tube container is that, for example, when a content such as a hair dye reacts with air to cause discoloration, the discoloration or modification significantly impairs the commercial value. I have a concern. Further, depending on the type of plastic, there is a concern that the gas barrier property is low and air permeates the wall surface to enter the plastic tube container and touch the contents to cause discoloration.

作の逆止弁を取り付けることで、内容物を押し出した後
の復元力による空気の呼び込みを阻止し、空気と内容物

The gas barrier property is secured by using a film with vapor deposited material, and a check valve manufactured separately is attached to its mouth to prevent air from being drawn in due to the restoring force after pushing out the content. However, the contact of air with the contents is avoided to prevent alteration of the contents.
