Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a dispensing cap having an opening and closing function which is tightly fitted to a bottle mouthpiece.

[Conventional technology]

A cap body that provides a part to be assembled to the bottle barrel and that forms a spout port, of a dispensing cap that is tightly fitted to the bottle barrel, and that is hinged to the cap body;
It is well-known that a lid body that opens and closes a spout of a cap body is known, and particularly, a hinge hinge structure between the cap body and the lid body has a mirror hinge structure. It is widely used because of its excellent use form, such as having a function of self-holding.

In addition, among the pouring caps that are closely fitted to the bottle barrel, a part of the cap body is cut off to form an opening, and the content liquid that is poured out of the pouring port is used as a pouring cylinder piece. The structure that regulates the guidance shows high safety until the product reaches the consumer, and also has a good function as a pouring cap, such as a good liquid liquid pouring form. It's being used.

[Problems to be solved by the invention]

However, in the case where the cap body and the lid are hingedly connected with a mirror hinge, when the pouring cap is in the closed position, the corners of the bent and sharply hinged pieces are bent from the outer peripheral surface of the pouring cap. It will be in a protruding state, which may cause injuries by hooking fingertips on the corners of the hinge piece protruding from the outer peripheral surface of the pouring cap, or cause inconvenience due to catching of the hinge piece with other articles such as feeling painful. There was a problem.

On the other hand, a part of the cap body is cut off to form an opening of the spout, and a pouring cap configured to guide and regulate the pouring form of the content liquid poured from the spout by the pouring cylinder piece. The sealing by the lid after the formation of the spout opening is performed by bringing the top plate of the lid fitted and assembled onto the upper portion of the cap body into close contact with the entire upper edge of the pouring cylinder piece, or This is achieved by tightly fitting the spigot piece hanging down on the top plate into the spout piece, but in any case, it is necessary to linearly assemble the lid to the cap body from directly above. Therefore, when the cap body and the lid body are hingedly connected, there is a problem that the sealing performance is reduced.

That is, when the lid is hingedly connected to the cap body, the height position of the top plate or the stopper piece of the lid relative to the spout cylinder piece of the cap body located at a relatively high position is restricted, and when the assembling is performed. Is inclined, so that it is not possible to obtain uniform pressing and close contact of the lid top plate with respect to the entire periphery of the upper end edge of the spouting cylinder piece, and it is possible to insert the stopper cylinder piece into the spouting cylinder piece. This is because, if it is configured so as to make it impossible to fit the plug piece into the spout piece in a tightly fitted state.

In order to solve the above-mentioned problems of the conventional technology, the present invention has the characteristics of the technology disclosed in Japanese Utility Model Laid-Open No. 2-37857, that is, the hinge piece does not protrude from the outer peripheral surface in the closed state, and the hinge shaft has Since it is located at both ends of the connecting plate piece that connects the cap body and the lid, utilizing the fact that the height position of the lid with respect to the cap body can be displaced by the length of the connecting plate piece, The technical problem is to achieve the cover of the lid body while rotating with respect to the cap body in a state where the lid body is positioned higher than the cap body. It is an object to ensure that this can be achieved with a hinged lid.

[Means for solving the problem]

Means of the present invention for solving the above technical problem is a dispensing cylinder which is closely fitted to a bottle cylinder and guides a content liquid which is dispensed from a spout opened by cutting a part of a bottom plate. And a cap body having a sealing cylinder piece erected through a short cylinder-shaped erection cylinder provided around the pouring cylinder piece on the peripheral edge of the upper surface. A cover body having a sealing cylinder piece for making the lower end face elastically contact the upper end edge of the sealing cylinder piece of the cap body in this assembled state. It has a flat plate shape, a pair of symmetrically arranged in a left-right symmetrical position with the top side facing the top side and the top side positioned rearward with respect to the bottom side in the closed state, and the lower leg side is hinged to the cap body. In addition to the hinge line, the upper leg side is hinged to the lid and hinged. Tsu between rear of flops body and a lid having a connecting plate pieces hinged, to the connecting plate piece and the cap body and a lid integrally molded of a soft synthetic resin material, in.

It is desirable to provide a concave portion for fitting the connecting plate piece on the rear outer peripheral surface of the cap body and to provide a concave portion for fitting the connecting plate piece on the rear outer peripheral surface of the lid body.

[Action]

In the open state of the lid with respect to the cap body, the elasticity exerted by the pair of connecting plate pieces themselves connecting the cap body and the lid, and the posture in which the pair of connecting plate pieces are inclined symmetrically to the left and right. As a result, the pair of connecting plate pieces maintain their original flat plate shape and self-hold the lid body in a substantially constant open posture.

When the lid is turned in the closing direction against the elasticity of the connecting plate piece from this open state, the connecting plate piece turns in the upright direction with the hinge line on the cap body side as a hinge axis, and Due to the rotational displacement in the upright direction, the lid is positioned higher than the cap main body by the length of the connecting plate piece as compared with the above-described open posture.

At the same time when the connecting plate piece is turned in the upright direction, the connecting plate piece is elastically deformed in a twisted form, but the torsion elastic deformation of the pair of connecting plate pieces is caused by the outer ends of the hinge lines, that is, both connecting lines. Since the rotation position at which the imaginary plane on which the bottom side of the plate piece is located and the imaginary plane on which the inner ends of the hinge lines, that is, the top sides of both connecting plate pieces are located, is performed as an almost inversion point, the lid is used. When the rotation of the body proceeds in the closing direction and the rotation displacement exceeds the elastic reversal point of both connecting plate pieces, the elasticity of the pair of connecting plate pieces acts to rotate the lid in the closing direction. .

When the lid is rotated with respect to the cap body just before the closed posture, the lower end surface of the seal cylinder piece of the lid body starts to elastically contact the upper end edge of the sealing cylinder piece of the cap body, and the lid body contacts the cap body. In a state in which the sealing cylinder is assembled in the closed position, the lower end surface of the sealing cylinder is closely elastically contacted with the upper edge of the sealing cylinder over the entire circumference,
Thus, the cap body is sealed and maintained by the lid body.

By the way, since the sealing tube piece is provided outside the pouring tube piece, it is naturally formed sufficiently low so as not to hinder the operation of discharging the content liquid through the pouring tube piece. And the rotation just before the closing posture of the lid,
By using the hinge line on the lid side located at the upper end of the upright connecting plate piece as the hinge axis, and being performed at a relatively high position with respect to the cap body, the rotational displacement of the lid body with respect to the cap body immediately before the closing posture is reduced. , Almost in a linearly descending state, so that a dense elastic contact of the lower end face of the sealing cylinder piece with the upper end edge of the sealing cylinder piece is achieved almost simultaneously over the entire periphery of the lower end face of the sealing cylinder piece. .

In addition, since the cap body, the lid, and the connecting plate are integrally formed of a soft synthetic resin material, when the lid is opened and closed, the connecting plate is easily twisted and deformed to exhibit a hinge function.
