A cap mechanism provided near the top of a dispenser container, wherein the cap mechanism is formed of at least a cap body and a cover plate integrally formed with the cap body, and the cap body is pressed by a stem of the dispenser. The cover plate is installed at a position directly above the part with a gap, and when the pressing force is not applied to the cap body part, the cover plate is installed at a position to close the tip opening part of the nozzle, and the resin is partially attached to the cap body part By forming the bullet-forming piece integrally or separately, when the pressing force is applied to the cap body part, the cover plate moves to a position where it comes off the tip opening of the nozzle, and the pressing force is released. When doing so, the cap body and the cover plate should return to their original positions.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap mechanism for a dispenser container, and more particularly to a cap mechanism for a dispenser container in which the opening at the tip of the nozzle is closed by a cover plate when not in use and the opening at the tip of the nozzle is opened when in use. .

[0002]

[Prior Art]

 For example, as a container for shampoo, rinse, milky lotion, etc., it is known that a dispenser which discharges contents through an internal pump by pressing a stem pressing portion provided on the head is attached. With such a dispenser container, it is not necessary to tilt the container to take out the contents, and it is easy to handle, and a fixed amount of contents can be taken out each time by operating the stem pressing portion.

By the way, in the above-mentioned dispenser, after the contents are discharged from the structure, it is usual that the discharged contents are left in the nozzle.

[0004]

[Problems to be solved by the device]

 For this reason, in the conventional dispenser, the content remaining in the nozzle becomes dripping over time and leaks from the opening at the tip of the nozzle to contaminate the surrounding area, or the content remaining in the nozzle is It dried and solidified at that place, which caused the passage clogging in the nozzle.

The present invention seeks to provide a cap mechanism for a dispenser container that solves the above problems.

[0006]

[Means for Solving the Problems]

 Therefore, in the present invention, a cap mechanism provided near the top of the dispenser container is formed by at least a cap body and a cover plate integrally formed therewith, and the cap body is a dispenser. It is installed directly above the stem pressing part of the cap with a gap, and when the pressing force is not applied to the cap body part, the cover plate is installed at the position that closes the tip opening of the nozzle and the cap body part. By forming a plastic elastic piece integrally or separately in a part of the cover, the cover plate moves to a position where it comes off the tip opening of the nozzle when pressure is applied to the cap body. A cap mechanism for the dispenser container is also characterized in that the cap body and the cover plate are returned to their original positions when the pressing force is released. Te, it is an unit for solving the problems.

[0007]

[Action]

 With the configuration of the present invention, even if the content remains in the nozzle after the dispenser is used, the cover plate closes the tip opening of the nozzle when the dispenser is not used, and the residual content leaks in the nozzle. The solidification of the contents in the nozzle will be completely prevented.

When the dispenser is used, the cap body is simultaneously pressed by the pressing operation of the stem pressing portion of the dispenser, and as a result, the cover plate is opened in conjunction with the pressing force of the cap body to open the tip opening of the nozzle. Will be done.

Further, when the pressing force on the cap body is released, the cap body returns to its original state due to the restoring action of the resin bullet, and as a result, the cap is once displaced from the tip opening position. The cover plate returns to the position immediately before the nozzle tip opening, and closes the nozzle tip opening again.

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. The first embodiment of FIG. 1 shows a lower opening type, and the second embodiment of FIG. 4 shows an upper opening type.

2 and 3 show a dispenser 1 in which a downward opening type cap mechanism according to the first embodiment is attached to the dispenser 1. The dispenser is usually made of polypropylene or the like, and is made of an appropriate material such as polyethylene or polyester. It is attached to container 2. A cap mechanism 4 is installed on the upper surface of the nozzle 3 protruding near the top of the dispenser 1.

In the cap mechanism 4, a base frame 5 made of a frame body having an appropriate shape is stably installed near the top of the dispenser 1, and a pin 6 is provided near one end of the base frame 5 so as to be rotatable. The cap body 7 to be attached faces the top of the dispenser with a gap 8 therebetween, and a resin elastic piece 9 is attached to the top of the cap body on the side opposite to the pin installation side. Is projected downward. This resin-made elastic piece may be integral with the cap body or may be separate.

An arm 10 extends from the cap body 7 along the nozzle 3, a cover plate 11 having an appropriate shape is attached to the tip of the arm 10, and an upper surface side of the arm 10 is formed with a cutout 12. There is. Due to the presence of the cutout portion, the downward movement of the arm 10 is smoothly performed.

The cover plate 11 is positioned so as to close the tip end opening 13 of the nozzle 3 in a normal state (see FIG. 2), and becomes flexible when a pressing force is applied to the upper surface of the cap body 7. The existing resin-made elastic piece 9 is bent, and the cap body is moved in the direction of the gap 8. As a result, the cover plate 11 moves downward together with the arm 10 to open the tip opening 13 of the nozzle 3. (See FIG. 3).

At this time, the applied pressing force also acts on the stem 14 of the dispenser 1, so that the stem 14 is moved up and down. As a result, contents such as cosmetics are discharged from the tip opening 13 of the nozzle 3 which is in communication with the stem 14.

The dispenser 1 is detachably attached to the container 2 with a cap 15, and a ball valve 16 is arranged at the upper end of the stem 14, and this ball valve 16 allows the outside air to flow from the nozzle 3 to the stem. It also functions as a check valve that prevents backflow into 14.

Next, FIG. 5 and FIG. 6 show an upper opening type cap mechanism of the second embodiment attached to the dispenser 1. The structure other than the cap mechanism is the same as that of the first embodiment.

In the cap mechanism 4 of the second embodiment, the relative positional relationship between the pin 6 and the resin-made resilient piece 9 is opposite to that of the first embodiment with the stem 13 as the center.

A notch 12 is formed on the lower surface side of the arm 10 extending from the cap body 7 along the nozzle 3. Due to the presence of the cutout portion, the upward movement of the arm 10 is smoothly performed.

The cover plate 11 is positioned so as to close the tip end opening 13 of the nozzle 3 in a normal state (see FIG. 5), and becomes flexible when a pressing force is applied to the upper surface of the cap body 7. The existing resin-made elastic piece 9 is bent, and the cap body is moved in the direction of the gap 8. As a result, the cover plate 11 moves upward together with the arm 10 to open the tip opening 13 of the nozzle 3. (See FIG. 6). The operation sequence for applying the pressing force and taking out the contents is exactly the same as in the first embodiment.

[0021]

[Effect of the device]

 Therefore, according to the present invention, it is possible to prevent the dripping of the nozzle portion without impairing the usability of the conventional dispenser by simply attaching the cap to the mouth of the conventional metering pump of the conventional dispenser, and to prevent the liquid from dripping in the nozzle passage. It has an excellent effect that it can prevent the contents of the product from drying and solidifying.
