[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap used for a container such as a bottle, and more particularly to a one-touch cap capable of closing or opening the mouth of the container by a single operation.

[0002]

2. Description of the Related Art Heretofore, a liquid detergent or the like or a granular seasoning or the like stored in a synthetic resin container or a glass container has been used. In many of these containers, a so-called one-touch cap that can be opened and closed by a single operation is attached to the mouth in order to facilitate the ejection of the stored contents. The one-touch cap has an elastic body formed on the cap body or the inner plug side engaged with the container body and a protrusion on the lid side so that the lid moves smoothly between the open position and the closed position. By working with the department
2. Description of the Related Art A structure capable of making a snap work when opening and closing a lid has been conventionally proposed. For example, Japanese Utility Model Publication No. 59-220
Patent Document 35: One-touch cap (first conventional example)
Has a structure in which a projection is formed on a part of the lid, while an elastic piece which is pressed by the projection as the lid rotates is provided on the cap body. 63-1
The one-touch cap (the second conventional example) according to Japanese Patent Publication No. 20857 is a one-touch cap having an inner plug, a cap body, and a lid, protrudes horizontally at the upper end of the inner plug, and has a cross section along with a side wall and a horizontal flange of the inner plug. An elastic piece having a U-shape is formed, and a projection formed on the lid presses the elastic piece with the rotation of the lid.

[0003]

However, in each of the first and second conventional examples, the elastic piece is formed in a cantilever shape, and the elastic force thereof mainly depends on the thickness and material properties of the elastic piece. If the pressing distance by the projection on the lid side is small, sufficient elastic force cannot be provided. In order to achieve sufficient snapping without changing the elastic piece, it is necessary to increase the eccentricity and increase the pressing distance by increasing the thickness of the projection of the lid, and at the same time, the pressing distance of the elastic piece. Therefore, there is a problem that the size of the one-touch cap becomes large. Especially,
In the second conventional example, the pressing direction of the projection is the vertical direction of the one-touch cap. However, if the height of the cap body cannot be secured due to a problem in the design of the container, the distance between the elastic piece and the horizontal flange of the inner lid is required. In addition, since the elastic piece is compressed against the side wall of the inner plug, not against the horizontal flange of the inner plug, there is a problem that sufficient snapping cannot be performed.

Accordingly, an object of the present invention is to provide a one-touch cap which can make sufficient snap work even when the pressing distance of the lid is short and can make the whole compact. It is in.

According to the invention of the present application, an inner plug attached to the mouth of a container, a cap body having a spout and formed with a recess from the top plate to the outer peripheral wall, and a plug for opening and closing the spout are formed. A one-touch cap comprising a projection having a projection that fits into the depression, wherein the projection of the lid is rotatable about the projection. In the inner plug, an elastic piece is formed corresponding to the formation position of the concave portion of the cap body, and the elastic body forms a V-shaped cross section with a horizontal flange formed in the inner plug. The elastic piece solves the above problem by proposing a one-touch cap which is pressed toward the horizontal flange by the projection with the rotation of the lid.

[0006]

According to the above-mentioned one-touch cap, when an external force is applied to the lid and the lid is rotated in the opening direction, the projection of the lid comes into contact with the elastic piece of the inner plug, and this elastic piece is attached to the horizontal flange. Bend to the side. Then, when the lid reaches a predetermined rotation position, the contact between the projection and the elastic piece is released, and the position is maintained unless a new external force is applied to the lid. That is, the lid is snapped during opening and closing operations, and the open position or the closed position is selectively and easily held. At this time, by forming a structure having a V-shaped cross section by the elastic body formed on the inner plug and the horizontal flange, when the protrusion on the lid body presses the elastic piece in the vertical direction of the container, a small pressing distance. Gives a stronger elastic force.
