えたものがある。``Problems to be solved by conventional technology and ideas'' Conventionally, caps with discharge ports used at the mouths of tube containers, squeeze containers, etc.
There is one equipped with a discharge valve as shown in Japanese Patent No.-80448.

させたものである。 Specifically, an outer cap with a discharge port protruding from the center of the top wall is fitted onto the outside of an inner cap with an open top wall, and the discharge port is equipped with a discharge valve on the inside. The tip of the discharge port is squeezed inward to form a valve seat, and the top wall of the outer cap is configured to be elastically deformable, and the valve body corresponding to the valve seat is attached to the top of the inner cap via a support piece. The valve seat is pressed against the valve body by the elasticity of the top wall of the outer cap.

不要で使用上頗る便利である。 Then, the inner cap is attached to the mouth of a container such as a tube container or a squeeze container containing cream-like contents, and by squeezing the container, the internal pressure is increased and the discharge port is advanced. That is, the normally closed discharge valve is opened by the internal pressure, and the contents are spouted out. In this way, it is not necessary to attach or detach the cap, which is extremely convenient for use.

There is an inconvenience that the discharge port retreats and is discharged to the outside.

そこで、本案は、そのような不都合を除去しよ
うとするものである。 Therefore, this proposal attempts to eliminate such inconveniences.

特徴とする。``Means for Solving the Problems'' In the present invention, an outer cap 2 having a discharge port 22 opened in the top wall 21 is fitted to the outside of the inner cap 1 with the top wall 11 open, and the outer cap 2 having a discharge port 22 opened in the top wall 21 is fitted inside the discharge port 22. Equipped with a discharge valve 3, the discharge valve 3 forms the inner edge of the discharge port 22 in the valve seat 31 and the outer cap 2.
The top wall 21 of the inner cap 1 is configured to be elastically deformable, and the valve body 32 corresponding to the valve seat 31 is connected and fixed to the top wall 11 of the inner cap 1 via support pieces 33 .
The umbilical valve seat 31 is brought into pressure contact with the elasticity of the outer cap top wall 21, and the discharge port 2 near the valve seat 31 is pressed.
It is characterized in that a plurality of protrusions 34... are arranged inside 2.

い。 After that, when the squeeze is released, the discharge port 2 that has advanced
2 retreats due to the elasticity of the top wall 21 of the outer cap, and the discharge valve 3 automatically closes. At this time, within the discharge port 22, a portion of the contents is directly pushed back toward the container body A side by the plurality of protrusions 34 that retreat together with the discharge port, and as a result, the surrounding contents also become viscous and It is attracted by fluid friction and the like and is pulled back toward the container body A side. Therefore, even if the contents spouted from the discharge port 22 are cut off while the container body A is being squeezed and the squeeze is subsequently released, the contents in the discharge port 22 will still flow through the protrusions 34... It is pushed back by the action of... and is not pulled back and expelled to the outside.
