Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a pump-type dispensing container suitable as a container for containing shampoo, liquid cosmetics, and the like. The present invention relates to a pouring container in which a pouring port is opened and closed by relative rotation with a cylinder.

"Prior Art" Conventionally, as a pouring container that opens and closes the pouring port by rotating an outer cylinder forming a cap, there is a container having a structure as shown in Figs. 7 and 8, for example. (See Japanese Patent No. 24427). This container includes a container body 1 having a screw cylinder portion 1a on an upper portion thereof, a spray nozzle 2 vertically movable in the screw cylinder portion 1a of the container body 1, and an outer periphery of the screw cylinder portion 1a. The intermediate cylinder 3 and the rotary cylinder 4 that is rotatable around the outer circumference of the intermediate cylinder 3 and that is interlocked with the intermediate cylinder 3 are roughly configured.

The container body 1 includes a threaded cylinder portion 1a having a spiral shape 5 on an outer surface,
A shoulder portion 1b that projects laterally from the lower surface of the screw cylinder portion 1a and a body portion 1c that extends downward from the shoulder portion 1b. The outer surface of the screw cylinder portion 1a and the shoulder portion 1b. Circumferential ridges slightly higher
1d is formed.

The spray nozzle 2 is fitted in the screw cylinder 1a so as to be vertically movable, a side surface thereof is provided with a nozzle hole 2a for spraying the content in the container body 1, and an upper end thereof is outwardly directed outward. The facing flange 2b is provided so as to project.

The middle cylinder 3 is a cylinder arranged on the outer circumference of the threaded cylinder portion 1a, and has a threaded shape 3a formed on the inner circumference thereof to be screwed into the threaded cylinder portion 1a, and is engaged on the outer circumference of the lower end portion. The ridge 3b is formed.

The rotating cylinder 4 is a cylinder arranged on the outer circumference of the middle cylinder 3, and has a vertical groove 4a formed on the inner circumference thereof to engage with the engagement protrusion 3b of the middle cylinder 3 and has a lower end. An engagement protrusion 4b that engages with the lower end of the peripheral protrusion 1d of the container body 1a is formed on the inner circumference of the portion. Then, when the rotating cylinder 4 is relatively rotated with respect to the container body 1, the middle cylinder 3 is rotated in conjunction with the rotating cylinder 4 and the outer circumference of the screw cylinder portion 1a is vertically moved. In this way, the middle cylinder 3
Is located at the upper limit, the upper end surface of the middle cylinder can be brought into contact with the lower surface of the outward flange 2b of the spray nozzle 2.

To spray the contents from the container body 1,
The rotary cylinder 4 and the rotary cylinder 4 are rotated relative to each other and the middle cylinder 3 is lowered to open the nozzle hole 2a to the outside and push the spray nozzle 2 downward. At this time, the amount of rotation of the rotating cylinder 4 is at least the amount of movement of the middle cylinder 3 and the stroke of the spray nozzle 2 is shortened, so that the spray amount of the contents can be reduced.

Further, in order to close the nozzle hole 2a after spraying the contents, the container body 1 and the rotating cylinder 4 are relatively rotated to raise the middle cylinder 3 contrary to the opening operation, and the nozzle hole 2a is closed. At this time, the outward flange 2b provided on the upper part of the spray nozzle 2
However, since it is located at the upper end of the middle cylinder 3, it is possible to prevent the spray nozzle 2 from being pushed down.

[Problems to be solved by the invention] By the way, in the pouring container having the above-mentioned structure, the nozzle hole 2a can be easily opened and closed by the relative rotation between the container body 1 and the rotating cylinder 4, and the usability in use is good. On the other hand, when the middle cylinder 3 is located at the upper limit, the catching surface with the screw cylinder portion 1a is reduced, which causes rattling with respect to the screw cylinder portion 1a and resistance to the tensile force and the compression force of the middle cylinder 3. The power becomes weak. In particular, since the resistance of the middle cylinder 3 to the compression force becomes weak, it becomes impossible to effectively prevent the spray nozzle 2 from being pushed down.

The present invention has been proposed in view of the above circumstances, and its object is to enable the opening and closing of the pouring portion with a simple structure and to prevent the middle cylinder from being at the upper limit. It is an object of the present invention to provide a pouring container that does not cause rattling and can reliably prevent the nozzle from descending.

[Means for Solving the Problem] Therefore, in the present invention, a bottomed cylindrical container body having a screw formed on the outer periphery of the mouth and a cap with a pouring nozzle attached to the mouth of the container body are provided. In the dispenser container, the cap is a dispenser nozzle, a pump mechanism for sucking up the liquid in the container body by the vertical movement of the dispenser nozzle, a screw connection to the outer periphery of the mouth, and an upper part of the dispenser nozzle. A middle cylinder screwed to the outer circumference of the inner cylinder having an insertion hole and covering the pouring nozzle at its ascending limit position, and a lower end inserted into the outer circumference of the middle cylinder so that the lower end is rotatable around the axis with respect to the container body. And an outer cylinder that engages with the inner cylinder, and a protrusion preventing protrusion of the spouting nozzle is provided on the inner surface of the insertion hole of the inner cylinder in a form extending in the vertical direction, and on the outer surface of the spouting nozzle. Is provided with an axially extending locking groove At the same time, an engaging protrusion is provided on the inner circumference of the upper part of the middle cylinder, and further, the pouring nozzle is lowered on the outer surface of the pouring nozzle at the lower limit position of the middle cylinder. It is characterized in that an insertion groove for inserting the lowering prevention ridge is sometimes formed.

[Operation] In the pour-out container thus configured, when the outer cylinder and the container body are relatively rotated, the middle cylinder rotates in conjunction with the outer cylinder, and the middle cylinder is screwed to the inner cylinder. Therefore, the screw action moves up and down while rotating inside the outer cylinder.

At this time, when the outer cylinder is rotated and the middle cylinder is fed in, the spout of the spout nozzle projects and opens from the upper end of the spout, and in this state the contents of the container body are pushed down by pushing down the spout nozzle. It becomes possible to dispense through the spout.

Further, when the outer cylinder is rotated in the opposite direction to the above-mentioned and the middle cylinder is paid out, the spout of the pouring nozzle is closed by this middle cylinder,
The contents in the container body cannot be poured out.

In this way, the middle cylinder moves up and down in the outer cylinder by the action of the locking mechanism and the screw mechanism of the mutually adjacent cylinders.

Furthermore, since the upper surface of the lowering protrusion in the inner cylinder is located on the lower surface of the pouring nozzle when the middle cylinder is extended,
It is possible to surely prevent the pouring nozzle from lowering.
