Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hinge cap, and more specifically, it prevents liquid dripping when pouring out contents and is excellent in usability, and it is also easy to fit the spout plug into the spout after use. The present invention relates to a hinge cap.

[0002]

[Prior art]

 Conventionally, as a cap of a container containing liquid, a hinge cap composed of a cap body fitted with a container mouth and a lid body hinged to cover the cap body has been used. . In this hinge cap, when the lid is closed, the spout plug provided on the inner surface of the lid is fitted into the spout portion provided on the top of the cap main body, and the inside of the cap formed on the top of the cap main body and the inner surface of the lid is closed. The content liquid was prevented from accumulating in the space.

In the conventional hinge cap, since the spout plug is fitted into the spout portion as the lid body moves to the cap body when the lid body is closed, the spout portion is located in the top of the cap body. It was located in the center. In other words, the lid rotates around the hinge and moves almost in the axial direction when it has moved to the vicinity of the cap body.Therefore, if there is a spout at the center of the top of the cap body, the lid will move with it. The spout plug can be fitted into the spout. However, in the hinge cap where the spout is located in the center of the top of the cap body, if the head space in the container is small, liquid will drip from the point when the container is tilted before the contents are poured out. However, there was a problem that it was inferior in usability. As a solution to this problem, we propose a cap that forms a dome-shaped top of the cap body and has a spout part diagonally above the position facing the hinge to prevent dripping during use. (Japanese Utility Model Publication No. 4-121256).

[0004]

[Problems to be solved by the device]

 However, in a hinge cap in which the spout is provided diagonally above the dome-shaped top of the cap body, the trajectory for closing the lid body to the cap body and the trajectory for fitting the spout plug into the spout are the same. Since it is not in the direction, it was difficult to fit the spout plug into the spout part with the movement of the lid body to the cap body when closing the lid. For this reason, in the above hinge cap, the separately prepared inner plug must be removed after opening the lid to take out the contents, and after use, before the lid is closed. Since it is necessary to install each one, there is a problem that opening and closing operations are very troublesome. In addition, there is also a problem that the lid made separately is likely to be lost, and if it is lost, there is no substitute and it is not possible to prevent liquid leakage in the space inside the cap.

[0005]

[The purpose of the device]

 Therefore, an object of the present invention is to provide a hinge cap which is excellent in the property of pouring out the contents, has no possibility of losing the spout plug, and can effectively prevent the liquid pool in the space inside the cap. Another object of the present invention is to provide a hinge cap capable of sealing a spout with a spout when the lid is opened and closed.

[0006]

[Means for Solving the Problems]

 The present invention has been proposed to achieve the above-mentioned object, and is formed on the inner surface of the cap body that is arranged in pressure contact with the spout portion that is formed in a slanting direction away from the hinge portion with respect to the cap axis line. The feature is that the spout plug is configured as a bulge. That is, according to the first aspect of the present invention, a cap body, which is composed of a top portion and a skirt portion having an upwardly convex shape, and which fits into a container mouth portion provided with a spout portion at the top portion, In the hinge cap, the inside of the hinge cap comprises an inlet plug that press-contacts and seals the inlet, and a lid that is openable and closable via a hinge so as to cover the top of the cap body. Provided is a hinge cap characterized in that the portion is formed at a position inclined in a direction away from the hinge portion with respect to the cap axis, and the spout plug is formed as a bulging portion that is in pressure contact with the spout portion. By fixing a separate member made of an elastic material to the spout plug portion, the pressure contact state with the spout portion can be made more liquid-tight.

Further, according to a second aspect of the present invention, a cap body that is fitted to a container mouth portion having an upwardly convex top portion and a skirt portion, and a spout portion provided at the top portion, In the hinge cap, the inside of the hinge cap is provided with an inlet plug that press-contacts and seals the inlet, and a lid that is provided so as to open and close via a hinge so as to cover the top of the cap body. The spout is formed at a position inclined with respect to the axis of the cap in the direction away from the hinge part, and the lid has a spout plug that fits into the spout at a position that matches the spout. Provided is a hinge cap characterized by being provided.

[0008]

[Specific explanation of the device]

 Since the hinge cap of the present invention is provided diagonally above the hinge part of the top part where the spout part projects upward, the content liquid can be poured out by tilting the container slightly. It is possible to effectively prevent dripping before pouring out the content liquid. Moreover, since the spout plug is provided so that it cannot be removed from the lid, there is no risk of losing the spout plug. Even if the track for pressing the spout plug into the spout does not match the track of the lid when closing the lid to the cap body, the spout plug pressed into the spout has a gentle curve. Due to the fact that it is configured as a bulging portion, the pressure contact between the spout and the spout is suitably achieved, and by pouring the separate elastic member to this part, pouring is possible. The pressure contact state between the mouth portion and the spout stopper is kept more liquid-tight, and the contamination of the space inside the cap with the content liquid can be effectively prevented.

In the first aspect of the present invention, in which the spout plug is composed of the bulging portion, the spout plug can be pressed against the spout portion in conjunction with the closing operation of the lid. That is, as described above, when the spout is installed diagonally above, the trajectory of pressing the spout with the spigot does not match the trajectory of the lid when closing the lid, so opening and closing Although it is difficult to link the movements, in the first aspect of the present invention, since the spout plug has elasticity, the spout plug deforms its shape by following the trajectory of the lid. When the lid is fixed to the cap body, the spout is completely covered and hermetically sealed by gradually pressing the spout.
