Abstract

PROBLEM TO BE SOLVED: To immediately restore a cut line by means of the restoring force of a rubber material or the like after the content corresponding to a force amount is extruded by external pressure for gripping a tube or the like. SOLUTION: For an automatic opening/closing nozzle, in a container such as a tube or the like housing a content 2 in a cream-like or half degumming state, a material having a restoring force such as rubber or the like is used for the exit of the tube or the like, and a cut line is made. Thus, the exit of the tube or the like and the content are maintained hygienic, and almost no content sticking occurs around the nozzle.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle provided with a cut in a resilient material such as rubber.

[0002]

2. Description of the Related Art The outlet of a tube or the like is open, and the contents of the tube or the like have been stored and used by directly contacting the brush portion of a toothbrush if it is a toothbrush, or directly contacting a finger or an affected part if it is a pharmaceutical.

[0003]

By eliminating external contact with the outlet of the tube and the like, it is possible to maintain much more hygiene to the outlet and the inside of the tube and the like, and also to prevent dirt and dust around the nozzle. Will be resolved.

[0004]

The problem is solved in that the cut is immediately closed by the restoring force of the material such as rubber after the content is extruded by the external pressure such as gripping the tube or the like.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A break in a material having a restoring force such as rubber is opened by pressurizing the contents, and closed when there is no pressure.

[0006]

By eliminating external contact with the outlet of the tube, etc., the sanitary condition of the outlet of the tube, etc. and the contents can be maintained much. Also, since the contents hardly adhere to the periphery of the nozzle, the vicinity of the cap and the nozzle can be improved. Almost no dirt residue.
