2. Description of the Related Art Conventionally, a cap that can be opened and closed with one touch without being detached from the cap body has been used in the field of liquid containers and the like. This type of cap generally consists of a cap body fitted with a container body and having a bearing, and a cover cap having a protrusion fittable to the bearing, and by rotating the cover cap about the shaft. , It is being opened and closed (Actually Sho 60-2144)
No. 9, etc.).

[0003]

[Problems of the Prior Art] In such a type of cap, since the airtightness at the time of closing the lid is not sufficient, if the content is liquid, liquid leakage may occur when it is swung or tumbled. Not only may this occur, but when the cover body is disengaged from the cap body provided on the cap top plate portion or the like at the time of opening / closing, the cover cap rotates about the shaft to open the lid. However, once the cover cap is rotated, it is structurally difficult to lock the cover cap at a fixed position, and the cover cap rotates until it hits the cap body or the container. In addition, the locking mechanism for controlling the rotation angle of the cover cap to be constant in this way generally tends to have a complicated structure, and in the most commonly used molding method such as injection molding,
There are problems that the manufacturing cost of the mold becomes expensive and the productivity is lowered.

[0004]

[Problems to be solved by the present invention] The purpose of the present invention is to
Easy to mold with a simple structure, the rotation of the cap can be regulated at a certain angle, and even if the contents are liquid, the airtightness is such that liquid does not easily leak. It is to provide an excellent cap that can be opened and closed with one touch.

[0005]

That is, according to the present invention, a cap body fitted into a container opening portion and an arch-shaped cover cap rotatably formed so as to cover the spout of the cap body. In the cap integrated with the rotating shaft, a curved concave surface is formed around the spout of the cap main body, and at the lower center both ends of the cap main body, a rotation part of the cover cap shaft is provided. A bearing that movably abuts, and stoppers that extend upward from the upper end of the bearing and that regulate the rotation of the cam portion of the shaft are formed on both side surfaces of the bearing. From a rotating part that fits into the bearing of the cap body, the lower part of which has a circular partial cross section, and the remaining part of which is a drop-shaped cam part that is continuous from the circular part and that has an acute angle at the upper part. Axis Cap and having is provided. In the present invention, it is particularly preferable that the bearing provided on the cap body has an inverted U-shape with an opening at the lower end of the cap body in view of restrictions in mold design and ease of mounting on the cap body. preferable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the configuration of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a partially cutaway sectional view showing an example of a cap body constituting a cap of the present invention. The cap body generally designated by 1 is composed of a fitting portion 3 which is fitted with a container opening portion (not shown) via a screw 2, and a skirt portion 4 which covers the container opening portion. The cap body 1 is provided with a spout 5 at the top, and a curved concave surface 6 is formed as a diaphragm around the spout 5. When the spout 5 is pushed downward by a cover cap described later by this diaphragm, an upward repulsive force for pushing up the arch-shaped cover cap acts.

That is, the shape of the spout of the cap body,
Together with the arched shape of the cover cap, the sealing property of the cap spout is remarkably excellent, and even if the content is a liquid such as shampoo, it can be shaken or fallen under normal use conditions. Liquid leakage does not occur easily.

Below the cap body 1, inverted U-shaped bearings 7 each having an opening at the lower end, which engage with a shaft of a cover cap described later, are formed on both sides so as to face each other through the center of the cap body. The movement of the rotating shaft is suppressed. A stopper 8 for restricting the movement of the cam portion connected to the rotary shaft is provided above the inside of the bearing 7, and this stopper also has a function as a reinforcing plate of the bearing portion. The shape of the bearing provided on the cap body may be simply by providing a hole corresponding to the shaft of the cover cap, but as shown in FIG. It is preferable because it can be easily molded when molding.

Next, in FIG. 2, which is a partially cutaway sectional view showing an example of a cover cap constituting the cap of the present invention, a cover cap generally designated by 10 has a side surface shape so as to cover the spout 5 of the cap body. For example, it has a substantially fan shape and is formed so that the front shape is arched.
A rotation shaft (cam) 12 for fitting with the cap body is provided on both sides of the inner surface of the essential portion 11 of the substantially fan-shaped portion. Further, on the inner surface of the central portion 13 corresponding to the spout 5 of the cap body of the arch-shaped cover cap 10,
A hemispherical protrusion 14 corresponding to the shape of the spout of the cap body is provided, and the distance between the rotary shaft 12 and the protrusion 14 is
By matching the distance between the upper portion of the bearing 7 of the cap body and the spout 5, the arch shape of the cap acts as a spring, and the hemispherical protrusion 14 of the arched cap pushes down the spout 5 of the cap body. It will act to adhere to.

The side surface shape and the front surface shape of the cover cap may be formed in any shape such as a hook-shaped arch shape other than the above-described substantially fan shape or gentle arch shape. is there. Further, the stoppers 8 formed on the cap body may be formed on both left and right sides, but either one may be formed. Further, the shape of the cap body is not particularly limited, and it is not limited to the cylindrical shape, but may be any shape such as a spherical shape.

In FIG. 3 showing an enlarged side view and a front view of the rotary shaft 12, the rotary shaft 12 constitutes a circular rotary portion 15 of which a part of the cross section forms the shaft, and the remaining part of the rotary shaft 12 is circular. The cam portion is composed of an acute angle portion 18 where the two tangents (the left tangent line 16 and the right tangent line 17) intersect with each other. There is. Therefore, it should be understood that the acute angle in the present invention does not mean a sharp angle but an angle smaller than a right angle.
When the rotating shaft 12 rotates by a certain angle when opening and closing the cover cap, the cam portion 18 is restricted by the stopper extending upward from the upper end of the bearing of the cap body, so that the rotating shaft cannot rotate any more. This allows the rotation of the cover cap to be controlled at a constant angle.

Next, in FIGS. 4 and 5 showing a state where the cap body shown in FIG. 1 and the cover cap shown in FIG. 2 are fitted, FIG. 4 shows a state in which the cap is closed, and FIG. , Shows that the cap is opened.

In FIG. 4, the bearing 7 of the cap body 1 is fitted with the rotary shaft 12 of the cover cap 10.
In this state, the left tangent line 16 of the cam portion of the rotary shaft 12
Is in contact with the stopper 8 of the cap body. The hemispherical protrusion 14 on the inner surface of the cover cap 10 is
The spout 5 of the cap body 1 is pushed down, and the upward force acts on the diaphragm 6. Therefore, when the protrusion 14 of the cover cap 10 and the spout 5 are disengaged, the cover cap 10 is biased by this upward force, but the rotation of the rotary shaft 12 is restricted by the left stopper 8a. Therefore, it will start rotating in the clockwise direction.

In FIG. 5 showing the state where the cover cap 10 is rotated and the cap is completely opened, the cover cap 10 has the right tangent line 17 of the rotary shaft 12 in the cap body 1.
The rotation of the cover cap 10 is restricted by coming into contact with the right side stopper 8b, so that the cover cap 10 does not rotate any more. When closing the cap, the cover cap 10 may be rotated counterclockwise to engage the spout 5 and the protrusion 14 on the inner surface of the cover cap.

Further, in the present invention, not only the rotary shaft of the cover cap is in contact with the left stopper 8a of the cap body when the lid is closed, but the top portion 19 of the acute angle portion 18 may be directed straight upward. . In such a case, the cover cap can be rotated in both clockwise and counterclockwise directions, and the opening angle is restricted to an angle of less than 45 ° in both directions.

The cap of the present invention can be molded by a known method such as injection molding of thermoplastic synthetic resin such as polyethylene or polypropylene, and the container to which the cap can be applied is made of any material such as plastic, metal and glass. It can also be applied to a given container. The cap of the present invention can be suitably used particularly in the field of liquid containers such as shampoo.

[0018]

According to the present invention, since the cap and the cap body are engaged with each other through the rotary shaft (cam) of a specific structure, the cap can be opened and closed at a constant angle with one touch. Moreover, since it has a simple structure in molding, it is excellent in productivity and economically preferable. In addition, since the cover cap and the spout are kept pressed against each other when the cap is closed, the container has excellent airtightness, and even if the contents are liquid, liquid leakage can easily occur due to rocking or tipping. It never happens.
