Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a dispensing cap for dispensing fluids such as liquids or creams.

``Prior art'' A circumferential wall having approximately the same diameter as the top and bottom that fits into the mouth and neck of the container is hung from the periphery of the top wall having the spout hole, and the mechanism is inserted from the rear of the top wall via an elastic reversing mechanism A cap is known that has a protruding lid plate which covers the spout hole and the upper surface of the top wall in an openable and closable manner by rotating around the lid.

``Problems to be Solved by the Invention'' The conventional cap described above is convenient because the spout hole can be opened and closed by elastically inverting the lid plate, and for this reason, it has become widespread and used in various containers.

However, it is not preferable for the cap of a cosmetic container and the cap of a detergent container to have the same appearance, for example, and it is desirable to have a different appearance depending on the purpose of the container.

From these viewpoints, the present invention not only changes the appearance of the above-mentioned cap, but also makes it easier to hold the container fitted with the cap by making the upper part of the cap a gripping part with a larger diameter. This prevents the cap from becoming thicker due to its larger diameter, making it easier to make from synthetic resin. Furthermore, the cap is made up of three parts, and the colors of each part can be changed to bring out the characteristics of the cap. It is.

"Means for Solving the Problem" A first circumferential wall 4 to be fitted into the mouth and neck of the container body is vertically disposed from the periphery of the first top wall 3 with the nozzle 2 that stands upward, and the first circumferential wall 4 is A cap body 1 made of synthetic resin that expands upwardly and outwardly from the upper part excluding the rear part and has a first fitting wall part 5 standing higher than the first peripheral wall 4, and a through hole 8 through which the nozzle is passed. A short cylinder 10 that covers the upper part of the first top wall inside the first fitting wall part with a second top wall 9 and is suspended from the lower edge of the through hole 8 is attached to the nozzle 2, and the second top wall peripheral edge part The second fitting wall part 11 vertically installed from the outer surface of the first fitting wall part 5,
A decorative board member 7 made of synthetic resin, in which arms 12, 12 are fitted together and protrude rearward from both left and right sides of the rear edge of the second top wall, and a shaft 13 is installed between the rear ends of these arms; Both the front and rear surfaces of the shaft are between the inner surface of the rear part of the second peripheral wall 16 which is suspended from the periphery of the third top wall 15, and the rear surface of the second peripheral wall 16 which is suspended from the rear part of the third top wall, and the shaft 13. The upper end of the nozzle and the upper surface of the second top wall can be freely opened and closed by the third top wall 15 by rotating about the shaft 13. A small protrusion 13a is attached to the lower surface of the shaft 13 so that the lid plate 14 can be elastically reversed when rotated about the shaft.

``Operation'' From the state shown in FIG. 1, when the front end of the cover plate 14 is pushed up against the cap body 1 and the decorative plate member 7 fitted to the cap body, the cover plate 14 opens around the shaft 13 and elastically reverses. do. That is, the cross-sectional shape of the shaft 13 is such that a small protrusion 13a is attached to the lower surface, and an elastic plate 17 hanging from the rear lower surface of the third top wall of the lid plate 14 and the peripheral edge of the third top wall are formed. Since both the front and rear surfaces of the shaft 13 are sandwiched between the inner surface of the rear part 16a of the second top wall 16 which is vertically disposed from After riding on the small protrusion 13a, it moves to the front side of the shaft 13, and at this time, the elastic plate 17 elastically returns and moves to the rear side of the shaft. By rotating in the opposite direction from the open state, the lid plate is elastically inverted again and closed. The nozzle is opened and closed by opening and closing the cover plate.

``Embodiment'' The cap of the present invention consists of a cap body, a decorative board member, and a lid plate, each of which is integrally molded from a synthetic resin material.

The cap body 1 has a first top wall 3 with a nozzle 2.
A first peripheral wall 4 that is fitted into the mouth and neck of the container from the periphery.
are vertically arranged, and the first fitting wall portion 5 is made to stand up higher than the first circumferential wall 4 by expanding upward and outward from the upper portion of the first circumferential wall excluding the rear portion thereof. A short wall 6 may be constructed between the rear ends of the first fitting wall by standing up from the rear part of the first top wall.

The decorative board member 7 covers the upper portion of the first top wall 3 inside the first fitting wall portion with a second top wall 9 having a through hole 8 through which the nozzle 2 is passed, and also extends from the lower edge of the through hole 8. The short tube 10 provided thereon is fitted into the nozzle 2, and the second fitting wall portion 11, which is provided vertically from the peripheral edge of the second top wall, is fitted into the first fitting wall portion 5, respectively. Further, arms 12, 12 are made to protrude rearward from both left and right sides of the rear edge of the second top wall, and a shaft 13 is installed between the rear ends of these arms.

The cover plate 14 has a second circumferential wall 16 hanging from the periphery of the third top wall 15 and an elastic plate 17 hanging from the rear of the third top wall. The shaft 13 is loosely inserted into the gap formed between the elastic plate and the rear inner surface of the second peripheral wall 16, and both front and rear surfaces of the shaft 13 are held between the elastic plate and the rear inner surface of the second peripheral wall 16. The diameter between the rear part of the second peripheral wall and the lower end of the elastic plate 17 is made smaller than the diameter of the shaft 13, so that the cover plate does not come off from the shaft 13. The cover plate is rotatable about the shaft 13, and opens and closes the upper end of the nozzle 2 and the upper surface of the second top wall 9 by its rotation. Upon opening and closing, the lid plate is elastically inverted. For this elastic reversal, a small protrusion 13a is attached to the lower surface of the shaft 13.

As shown in FIG. 3, the first fitting wall part 5, the second fitting wall part 11 of the decorative board member 7, and the second fitting wall part 11 of the cover plate 14 are connected to the lower part of the first circumferential wall 4 of the cap body. The peripheral wall 16 forms a large diameter section at the top of the cap.

"Effect of the invention" The present invention expands the first fitting wall part 5 upwardly and outwardly from the upper part of the first circumferential wall of the cap main body 1 and stands up.
The second fitting wall 11 extending vertically from the peripheral edge of the second top wall 9 is fitted to the outer surface of the first fitting wall, and the upper surface of the second top wall is fitted with the third top wall 15 of the cover plate 14. Since it is closed, the upper part of the cap has a larger diameter than the lower part, which makes it unique in appearance compared to conventional caps with elastic reversal mechanisms, and the large diameter part of the cap has a larger diameter than the lower part. Since the container with the cap can be used as a gripping part, when lifting the container with the large diameter part, the hand does not slip, making it easy to hold. Since the diameter portion is formed by the first fitting wall portion 5 of the cap body, the second fitting wall portion 11 of the decorative board member, and the cover plate 14, the upper portion of the cap is thickened and the synthetic resin material is cooled. Does not cause sink marks etc.
Since the cap is made up of three parts: the cap body, the decorative board member, and the lid plate, the cap can be given a distinctive character by making these parts different colors.
Furthermore, the elastic reversal mechanism of the cap according to the present invention has a shaft 13.
An elastic plate 1 with a small protrusion 13a attached to the lower surface and both front and rear surfaces of the shaft hanging from the rear of the third top wall 15.
7 and the inner surface of the rear part 16a of the second peripheral wall 16 hanging from the periphery of the third top wall. Since it is provided so that it can be elastically reversed by running onto the small protruding portion 13a and moving toward the inner surface of the shaft, the mechanism can be simplified.
