Description

[Detailed description of the invention] <<Field of industrial application>> The present invention relates to a cap opening structure for a container with a cap, and more specifically, the invention relates to a cap opening structure for a container with a cap, and more specifically, a container having a relatively large diameter body for accommodating contents and an open end. An inner stopper is fitted into the open end of a container formed integrally with a relatively small-diameter neck via a shoulder, and a protrusion is formed in the center of the inner stopper, and the outer circumference of the protrusion is A small hole is bored in the inner stopper, and a cap having a spout on the top surface is attached above the inner stopper so as to be movable in the vertical direction. When the cap is in the upper position, a gap is formed between the protrusion of the inner stopper and the spout of the cap, allowing the contents to be poured out. This invention relates to a cap opening structure for a container with a cap.

≪Prior Art≫ Shampoo containers are common as conventional containers with caps as described above, in which the cap is screwed onto the neck, and when the cap screw is tightened, the spout of the cap is blocked, and conversely, the cap is closed. The cap has an opening structure in which when the screw is loosened, the spout of the cap opens and the contents can be taken out.

However, in order to open and close the cap of this shampoo container, it is necessary to grasp the body of the container with one hand and rotate the cap with the other hand, so when washing hair, it is necessary to hold the handle of the shower with one hand. If you are pouring hot water on your hair, opening and closing this cap is relatively troublesome, and it is also troublesome to close the cap after pouring out the shampoo solution, so if you leave it as it is, it may cause some problems. Problems such as shampoo containers falling over and spilling their contents were often experienced.

≪Problems to be solved by the invention≫ The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a container with a cap of the above type, such as a shampoo container, by one-touch operation of the cap with one hand. To provide a cap opening structure that can be opened and closed extremely easily.

<<Means for solving the problem>> In order to achieve the above object, according to the cap opening structure of the present invention, in the above-mentioned conventional container with a cap, a flexible ring body is disposed inside the cap. , a protrusion is formed on the side wall of the ring body, the protrusion is made to protrude outward from the side wall of the cap, one of the surfaces where the lower end of the ring body makes sliding contact with the shoulder of the container is an inclined surface, and the protrusion is made to protrude outward from the side wall of the cap. By pressing inward, the ring body and the cap connected thereto are pushed up through the inclined surface to occupy an upper position.

<<Example>> Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 indicates a relatively large diameter cylindrical body of a container for storing shampoo liquid, etc.;
A relatively small-diameter neck portion 3 is integrally formed above the shoulder portion 2 whose upper surface is a conical inclined surface. The upper end of this neck portion 3 is an open end 3a, into which the inner stopper 4 is placed. That is, the inwardly facing flange 4a at the lower end of the inner stopper 4 is fitted into the outer circumferential groove of the neck 3, so that the inner stopper 4 does not come off from the neck 3. A truncated conical protrusion 5 is integrally formed in the center of the inner stopper 4, and a plurality of small holes 6 are bored around the outer periphery of this protrusion.

This inner stopper 4 is covered with a cap so as to surround it, and this cap consists of a cylindrical cap body 7 and a ring body 8. The cap body 7 is a synthetic resin molded product with sufficient rigidity, and includes a disc-shaped ceiling surface 9 having a diameter approximately the same as the outer diameter of the container body 1, and a cylindrical peripheral wall portion 10 hanging from the periphery of this ceiling surface. has. A truncated cone-shaped spout 11 is formed in the center of the ceiling surface, and the shape of the spout 11 matches the shape of the protrusion 5 of the inner stopper 4, so that the cap body occupies a lower position. At times, the protrusion 5 of the inner stopper 4 tightly fits into the spout 11 to close it. A pair of circular through holes 12-12 are formed in the cylindrical peripheral wall portion 10 at symmetrical positions facing each other. Further, a fitting cylindrical portion 13 having a diameter slightly larger than the outer diameter of the neck portion 3 of the container is integrally formed to hang down from the inner periphery of the lower ceiling surface of the cap body 7. A first annular projection 14 is formed, and a second annular projection 15 is formed on the outer peripheral surface of the intermediate portion of the neck portion 3.
After the first annular projection 14 of the cap body 7 passes over the second annular projection 15 of the neck portion 3 and is fitted as shown in FIG. 2, the cap body 7 cannot be separated from the neck portion 3. and the second part of the neck part 3
The annular protrusion 15 is connected to the fitting cylindrical portion 13 of the cap body 7.
The cap body 7 is in pressure contact with the inner surface of the cap body 7.
Friction welding is used to prevent it from falling under its own weight even when it is in an appropriately raised position.

The ring body 8 is housed within the cap body 7 and is molded from synthetic resin so as to be flexible in the radial direction, and has a pair of pin-shaped protrusions 16 on its side wall.
-16 is planted. When the ring body 8 is stored in the cap body 7 from below, the pin-shaped protrusions 16-16 are inserted into the cap body 7.
The two are assembled inseparably by protruding outward from a circular through hole 12-12 formed in the peripheral wall of.

<<Operation>> Now, in the state shown in FIG. 2, the cap main body 7 configured as described above occupies a position below the neck 3 of the container, and the protrusion 5 of the inner stopper 4 is in close contact with the spout 11 of the cap main body 7. It's blocking this. In this state, the lower end corner of the ring body 8 is in contact with the lower upper surface of the inclined surface formed on the shoulder 2 of the container. From this state, pressurize the pin-shaped protrusions 16-16 protruding outward from the side wall 10 of the outer cap body 7 with fingers from both sides, and shape the ring body 8 into an oval shape as shown by the chain line in FIG. When deformed, the lower end corner of the ring body 8 comes into sliding contact with the sloped surface of the shoulder 2 of the container, which is an uphill slope. Therefore, the reaction force that the ring body 8 receives from the shoulder 2 of the container is perpendicular to this inclined surface and includes an upward component force. The upward force acting on the ring body 8 acts to push the cap body 7 upward, and this force causes the spout 11 of the cap body 7 to close to the inner stopper 4.
A gap is formed between the protrusions 5 and 5;
By inverting the container, the contents can freely flow out of this spout 11. After use, when the cap body 7 is pushed in, the cap body 7 is held in the raised position because the inner wall surface of the cylindrical portion 13 is frictionally joined to the second annular projection 15 of the neck portion 3. Therefore, the cap body 7 easily moves downward, and the protrusion 5 of the inner stopper 4 tightly fits into the spout 11 of the cap body 7 to close it.

In this embodiment, the lower end of the ring body 8 is approximately at a right angle, and the shoulder of the container that comes into contact with it is an inclined surface. However, the present invention is not limited to this. It is also possible to form a container so as to abut the joint corner between the body 1 and the shoulder 2 of the container. Even in this case, a component of force is generated that pushes the cap body upward in the same way as above. Further, both of the contact surfaces between the ring body 8 and the container may be sloped surfaces.

Furthermore, the container with a cap of this invention is not limited to a cylindrical shape, but can also be applied to a rectangular container, and may be formed into a rectangular tube shape.

<<Effect of the invention>> As described above, in this invention, the cap body can be opened by a one-touch operation of pushing inward the protrusion protruding outward from the side surface of the cap body. This is easy and quick, and the protrusion can be pushed in with the thumb and forefinger of one hand while holding the container with the other hand, making it extremely convenient for shampoo containers, etc. that require opening the cap body with one hand. Become something.

In addition, the above-mentioned projection for the opening operation is embedded in the peripheral wall of the ring body, and this projection protrudes outward through the through hole formed in the peripheral wall of the cap body. Even a viewer can intuitively understand that by pressing this protrusion, the cap body can be opened, and since the pressing position is specifically indicated, it is extremely convenient to use. be.
