[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge cap mounted on a mouth and neck of a container containing various contents such as liquid and powder.

[0002]

2. Description of the Related Art Conventionally, a synthetic resin hinge cap having a reversing plate for automatically closing the lower lid having a spout and an upper lid for closing the lower lid and having the upper lid closed automatically is a cap. It can be easily opened and closed, and is often used in cosmetics and daily necessities. However, since a cut line is formed at the top of the top lid, dirt and dust can be found on the cut line during product display. It is easy to accumulate and is therefore difficult to use for food.

A hinge cap without a reversing plate, which is used for a container containing a seasoning or the like in the field of foods, has an upper lid which is closed by its own weight when the container is tilted to dispense the contents. To hinder the dispensing operation.

In order to solve this drawback, there are known those described in Japanese Utility Model Publication No. 57-39330, Japanese Patent Publication No. 63-11227, and Japanese Utility Model Application Publication No. Sho 56-84951.

[0005] The technical content disclosed in Japanese Utility Model Publication No. 57-39330 is that a pair of hinge portions are projected at a proper interval at a boundary portion between an upper cover and a lower cover, and between the hinge portions of the upper cover,
A locking piece projecting diagonally downward and outward is provided, and when the upper lid is rotated in the opening and closing directions about the hinge portion, the tip of the locking piece climbs over the upper end of the peripheral wall of the upper lid.

Therefore, even when the upper lid is opened and the tip of the locking piece has passed over the upper end of the peripheral wall, even if the container is tilted, the upper lid does not hang down to the outlet side due to the resistance of the tip of the locking piece. Since the opening angle is maintained, there is no hindrance to the dispensing operation.

Further, in this conventional technique, since no reversing plate is formed, there is no cut line at the top of the upper lid, so that the problem of dirt and dust adhering to this portion is also solved.

[0008]

However, in the above-mentioned prior art, the locking piece and the ridge come into contact with each other at an opening angle of the upper lid of approximately 90 degrees, and the open state of the upper lid is maintained. The rotation is not performed automatically, and it is necessary to open the lid up to 90 degrees with a finger.

If the opening of the upper lid is less than 90 degrees, there is a problem that if the container is tilted to take out the contents, the lower lid will be covered with the upper lid.

That is, in the prior art, in order to exert the performance of the cap, it is necessary to exactly rotate the upper lid until the locking piece gets over the ridge.

For this reason, it is difficult to open the upper lid to approximately 90 degrees in a hurry in daily life or by opening the upper lid with the thumb while holding the upper part of the container with one hand, which is inconvenient.

The present invention has been made in view of the above-mentioned problem, and an object of the present invention is to provide a lower lid having a spout and an upper lid for closing the lower lid connected by a hinge portion. Another object of the present invention is to facilitate the opening operation of the upper lid while solving the problem of dirt and dust adhesion in a synthetic resin hinge cap.

[0013]

According to a first aspect of the present invention, there is provided a hinge cap according to the first aspect, wherein both lateral ends are connected to the outer cylindrical portion between the hinge portions of the lower lid, and the upper lid is connected to the lower lid. When the lid is crowned, it is pressed radially outward of the lower lid by the outer surface of the hanging piece, and when the upper lid is opened, the radially inner side of the lower lid with respect to the hanging piece is opened. The elastic plate which gives the force which moves to is provided.

That is, an outer cylindrical portion attached to the container body,
A lower lid having a ceiling having a spout, a top wall having a shape capable of covering the ceiling of the lower lid, a cylindrical portion hanging down from a periphery of the top wall, and an inner surface side of the top wall. An upper lid provided with a plug body that hangs from the lower lid and closes a spout of the lower lid, and a cylindrical portion of the upper lid and an outer cylindrical portion of the lower lid formed by a pair of hinge portions provided at intervals. And a hinge cap made of a synthetic resin, which is integrally connected, and a hanging piece extending downward is provided between both hinge portions of the upper lid,
On the other hand, a protruding wall is erected on the ceiling part slightly inward from between the two hinge parts of the lower lid, and when the upper lid is opened and closed with the hinge part as a fulcrum, the tip of the hanging piece is In one configured to abut on the protruding wall and slide on the protruding wall surface, between both hinge portions of the lower lid, both lateral ends are connected to the outer cylinder portion, and the upper lid is When crowned on the lower lid, the outer surface of the hanging piece is pressed radially outward of the lower lid, and when opening the upper lid, the radius of the lower lid relative to the hanging piece An elastic plate for applying a force to move inward in the direction is provided.

[0015]

When the upper lid of the hinge cap constituted by the above-mentioned means is mounted on the lower lid, the outer surface of the hanging piece comes into contact with the inner surface of the elastic plate, and the elastic plate is moved radially outward of the lower lid. It is pressed and elastically deformed. In this state, when the upper lid and lower lid are released by hand, the elastic plate is restored to the inside of the lower lid in the radial direction. The top lid slides on the protruding wall surface, and the top lid rotates obliquely upward about the hinge.

As described above, when the upper lid is opened, the upper lid is automatically opened simply by unlocking the upper lid and the lower lid with a finger while holding the container body with one hand.

The opening action of the upper lid 3 is assisted, and the opening speed is increased.

<Second Embodiment> FIGS. 7 to 10 are views showing a second embodiment of the present invention, and FIG. 7 is a perspective view of the second embodiment of the present invention in which a lower lid and a part of an upper lid are partially cut away. It is.

First, the construction differs from the first embodiment in that a projection 26 is provided from the upper end surface of an elastic plate 19 extending from the outer cylinder 9 of the lower lid 2.

The protruding portions 26 are provided at right and left positions as viewed from the outer surface of the upper cover 3 which is located just below the hanging piece 24, and are also provided upright on the upper side of the elastic plate 19. The outer surface of the elastic plate 19 below the projection 26 has a thickened shape.

The thin width of the hinge 15 connected to the outer cylinder 9 is, for example, 2.5 mm.

The other structure is not different from the first embodiment.

Next, the operation will be described.

[State of Opening the Upper Lid] As shown in FIG. 8, when the upper lid 3 is opened at an angle of about 90 degrees, a projection 26 projecting from the upper end surface of the elastic plate 19 is formed at the lower end of the cylindrical portion 22 of the upper lid 3. Is lightly abutted. This allows
Even if the container main body 1 is tilted in the opened state of about 90 degrees, the container body 1 does not rotate so as to approach the lower lid 2 by the weight of the upper lid 3.

When the upper lid 3 is fitted to the lower lid 2 after the contents of the container body 1 are taken out, when the upper lid 3 is lightly pressed against the lower lid 2, the protrusion 26 And the lower end of the tubular portion 22 are in contact with each other,
Are slightly offset in the radial direction. This means that hinge 1
This is because, since the width of the thin portion 5 is formed to be relatively large, the elastic deformation of the hinge portion 15 can be performed smoothly without generating a feeling of resistance.

Then, in a state where the upper lid 3 is completely worn,
As shown in FIGS. 9 and 10, the projection 26 protruding from the upper end surface of the elastic plate 19 is located outside the cylindrical portion 22 of the upper lid 3.

Therefore, the projection 26 and the cylinder 22 come into contact with each other at an opening angle of the upper lid 3 of about 90 degrees shown in FIG. 8, but the projection 26 is located at a position outside the cylinder 22 in the subsequent fitting process. Therefore, the two can be smoothly fitted without contacting each other.

A thin portion 28 is formed at a position near the end face of the cylindrical portion 22.

The hanging piece 24 is positioned so that the outer surface of the hanging piece 24 strongly presses the inner surface of the elastic plate 19 when the upper lid 3 is attached to the lower cover 2. Further, a stopper 29 protrudes inward from the back side of the flange 25.

Next, the operation will be described.

[State in which the upper lid is attached to the lower lid] As shown in FIG. 12, the elastic plate 19 and the hanging piece 24 are in contact with each other.
4 is curved inwardly from the thin portion 28. The stopper 29 is fitted in the concave portion 27, and the upper cover 3 is fitted in the lower cover 2.

[State in which the upper lid is opened] As described above, when the upper lid 3 is mounted on the lower lid 2, the elastic plate 19 and the hanging piece 24 abut, and the upper part of the elastic plate 19 is slightly outward. Since the hanging piece 24 is curved more inward than the thin portion 28, when the stopper 29 is released from the concave portion 27, the upper lid 3 is quickly opened.

As described above, in the hinge cap of the third embodiment, the following effects can be obtained in addition to the effects (1) and (2).

(4) The elastic plate 19 is installed at an intermediate height in the vertical direction of the lower cover 2, and a concave portion 27 is formed at the convex edge 20 of the lower cover 2 in the direction opposite to the hinge 15, while the upper cover 2 3
The hanging piece 24 extending from the cylindrical portion 22 has a thin portion 28 near the end face of the cylindrical portion 22 and a stopper 29 protruding inward on the back side of the flange portion 25. 2, the elastic plate 19 and the hanging piece 24 are in contact with each other, and the upper part of the elastic plate 19 is slightly outwardly curved, and the hanging piece 24 is curved more inward than the thin portion 28. When the stopper 29 is released from the cover 27, the upper cover 3 is quickly opened.

Although the embodiment has been described with reference to the drawings, the specific configuration is not limited to the embodiment, and even if there are changes and additions without departing from the gist of the invention, the invention is included in the invention. It is.

For example, in the second embodiment, the protruding portion 26 is in a positional relationship in contact with the outer surface of the outer cylindrical portion 9 of the upper lid 3, but may be in contact with the hanging piece 24 of the upper lid 3.

Although the upper lid 3 and the lower lid 2 have been described as being formed integrally with each other, they may be formed separately and assembled.
