Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap that can be opened and closed with one touch, and more particularly to an arched cap that can regulate the rotation of the cap at a certain angle without requiring a special mechanism.

[0002]

[Prior Art]

 Conventionally, caps that can be opened and closed with one touch without detaching from the cap body have been used in the field of liquid containers and the like. This type of cap generally comprises a cap body fitted with a container body and having a bearing, and a cover cap having a protrusion capable of fitting with the bearing, and the cover cap rotates about the shaft. Therefore, the opening and closing is performed (Japanese Utility Model Laid-Open No. 60-21449, etc.).

[0003]

[Problems to be solved by the device]

 In such a type of cap, when the cover body is disengaged from the cover body provided on the cap top plate portion or the like when opening and closing, the cover cap is rotated about the shaft to be opened. However, once the cover cap is rotated, it is structurally difficult to lock the cover cap at a fixed position, and the cover cap will rotate until it hits the cap body or container. In addition, the locking mechanism for controlling the rotation angle of the cover cap to be constant in this way tends to have a complicated structure in general, and the molding cost of the mold is expensive in the most commonly used molding method such as injection molding. In addition, there is a problem that productivity decreases.

[The purpose of the device]

 Therefore, an object of the present invention is to provide a cap that can be opened and closed with one touch, which can regulate the rotation of the cap to a certain angle while having a simple structure and easy molding.

[0004]

According to the present invention, a cap body fitted to a container mouth and an arch-shaped cover cap rotatably formed so as to cover the spout of the cap body are provided. In a cap that is integrated by a rotating shaft, bearings that rotatably abut with the rotating portion of the shaft of the cover cap are provided at both lower central ends of the cap body, and bearings are provided on both side surfaces of the bearing above the upper end of the bearing. A stopper is formed that restricts the rotation of the cam portion of the shaft, and the lower ends of the cover cap that fit into the bearings of the cap body have a circular partial cross section. There is provided a cap, characterized in that it has a shaft composed of a rotating part and a remaining part and a drop-shaped cam part which is continuous with the circular part and whose upper part forms an acute angle. 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 on mold design and ease of mounting on the cap body. preferable.

[Specific explanation of the device]

 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 thereof, 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 that pushes up the cover cap acts.

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

Next, in FIG. 2, which is a partially cutaway cross-sectional view showing an example of a cover cap that constitutes 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 is formed in a substantially fan shape and its front shape is arched, and a rotary shaft (cam) 12 for fitting with the cap body is opposed to both sides on the inner surface of the main portion 11 of the substantially fan shape. Is provided. A hemispherical protrusion 14 corresponding to the shape of the spout of the cap body is provided on the inner surface of the central portion 13 of the arch-shaped cover cap 10 corresponding to the spout 5 of the cap body, By matching the distance of the protrusion 14 with 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 arch-shaped cap becomes the cap. It works so that the spout 5 of the main body is pressed down and adheres closely.

The side and front shapes of the cover cap may be formed in any shape such as a hook-shaped arch shape other than the above-described substantially fan-shaped or smooth 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 the cap body is not limited to the cylindrical shape but may be formed in 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 having a part of its cross section forming a shaft, and the remaining part thereof has a circular shape. It forms a cam part consisting of an acute-angled part 18 where two tangents (left tangent 16 and right tangent 17) intersect with each other. This cam part as a whole has a substantially drop shape (amadare shape). Have 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 can rotate further. This makes it possible to control the rotation of the cover cap at a constant angle.

Next, in FIGS. 4 and 5 showing a state in which 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. Further, the hemispherical protrusion 14 on the inner surface of the cover cap 10 pushes down the spout 5 of the cap body 1, which causes an upward force to act 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 starts to rotate in the clockwise direction.

In FIG. 5 showing the state where the cover cap 10 is rotated and the cap is completely opened, in the cover cap 10, the right tangent line 17 of the rotating shaft 12 is in contact with the right stopper 8b of the cap body 1. The rotation of the cover cap 10 is restricted by this, so that the cover cap 10 cannot 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 rotation axis of the cover cap is in contact with the left side stopper 8a of the cap body when the lid is closed, but the top portion 19 of the acute angled portion 18 may be directed straight upward. . In such a case, the cover cap can be rotated in either the clockwise direction or the counterclockwise direction.

The cap of the present invention can be formed by a known method such as injection molding of a 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 or glass. It can also be applied to special containers. The cap of the present invention can be suitably used particularly in the field of liquid containers such as shampoo.

[Effect of the device]

 In the present invention, since the cap and the cap body are engaged with each other through the rotation shaft (cam) of a specific structure, the cap can be opened and closed at a constant angle with one touch, and at the time of molding. Since it has a simple structure, it is excellent in productivity and economically preferable. Further, since the cover cap and the spout are kept pressed against each other when the cap is closed, the airtightness of the container can be maintained.
