[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container in which a hinge portion is provided on an upper peripheral wall of a container for liquid, particularly an upper peripheral wall of a container body, and the peripheral wall is a lid which can be opened and closed.
[0002]
[Prior art]
2. Description of the Related Art In a liquid container, a container in which a removing portion forming a spout is provided on a top wall of the container and a spout is formed by pulling up a finger hook ring is conventionally known.
Further, a liquid container in which a spout that protrudes outward from an upper end portion of a peripheral wall of the liquid container and in which a top wall member that covers the spout is removed is also conventionally known.
[0003]
[Problems to be solved by the invention]
However, in the former container, since the spout is formed on the top wall, the liquid flowing out of the spout at the time of pouring may flow out in an unexpected direction due to lack of guidance. To drain the remaining liquid, the container is inverted, but it has not been easy to discharge all the liquid.
In the latter container, since the spout is provided on the side of the container body, there is a problem that the spout is deformed by contact with other containers during transportation, and sometimes the break part is cut and the liquid leaks. Was.
[0004]
An object of the present invention is to provide a liquid container in which a technical problem is solved to solve the above-mentioned problems, and a hinge portion is formed at an upper end portion of a peripheral wall of a container main body, and the peripheral wall itself is used as a lid that can be freely opened and closed. Aim.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a liquid container, wherein a thin hinge portion is formed on an upper peripheral wall of a container body along an intersection line with a predetermined inclined surface, and the hinge portion is used as a boundary. The peripheral wall is bent inward to form an opening / closing lid that forms a curved surface that is symmetrical to the peripheral wall with respect to the inclined surface, and a lip portion that engages with the inner surface of the container top wall along the opening / closing lid is formed. The upper end of the lip and the opening / closing lid are connected by a thin break portion.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, 1 is a container body, 2 is a top wall, and 3 is an opening / closing lid, which is integrally formed of synthetic resin.
The container body 1 is composed of a substantially cylindrical lower peripheral wall 1a and an upper peripheral wall 1b extending upward continuously from the lower peripheral wall 1a, and the upper end thereof projects upward from the top wall 2 to form an upper end edge 4. ing.
As shown in FIG. 2, four concave surfaces 5 are formed in the upper peripheral wall 1 b, and a corner portion between the concave surfaces is an arc peripheral wall 6 extending from the lower peripheral wall 1 a and having an arc of a predetermined radius at the upper edge 4. Has become.
[0007]
As shown in FIG. 3, a thin hinge portion 7 is formed on one arc peripheral wall 6 along an intersection line with a predetermined inclined surface, and the peripheral wall is bent inward from the hinge portion 7 as a boundary. The opening / closing lid 3 is formed so as to be a curved surface that forms a plane of symmetry with the arc peripheral wall with respect to the inclined surface.
The upper edge 8 of the opening / closing lid 3 is formed so as to be flush with the upper edge 4 of the upper peripheral wall 1b, and has substantially the same shape as the upper edge 4 of the circular arc peripheral wall 6 portion.
[0008]
A lip 9 is formed on the upper surface of the container top wall 2 so as to engage with the inner surface of the container 3 along the opening / closing lid 3, and between the upper end edge of the lip 9 on the opening / closing lid side and the opening / closing lid 3. Is formed with a thin break 10.
A flange 11 is provided at a lower end of the container body, and a thin bottom plate 12 is joined to a lower surface thereof.
The bottom plate 12 is fused after the filling of the content liquid to seal the content liquid.
[0009]
Next, the operation and effect of the above configuration will be described.
When opening the liquid-filled container, put a finger on the upper edge 8 of the opening / closing lid 3 and pull it outward to cut the thin-walled rupture portion 10 and open it. It is bent outward to form a spout 13 as shown in FIG.
[0010]
At this time, since the opening / closing lid 3 is formed so as to be symmetric with the arc peripheral wall 6 with the hinge 7 as a boundary, the lid 3 is elastically opened outward by a spring action to have the same shape as the arc peripheral wall 6. The lip 9 forms the spout 13.
The central portion of the upper edge 8 of the opening / closing lid 3 projects from the upper edge 4 of the upper peripheral wall 1b, and acts to make the outflow direction constant when the content liquid is poured out.
[0011]
When the spout 13 is to be closed while the contents are left in the middle of use of the container, if the lid 3 is pressed inward, the lid 3 is bent inward at the hinge 7, Since it is resiliently engaged with the lip 9 by the spring action, the spout 13 is closed and the container is sealed, so that dust does not enter.
[0012]
Next, another embodiment will be described.
In the above embodiment, a concave surface is provided on the upper peripheral wall, and an arc peripheral wall is formed at the corner. However, in the present embodiment, a substantially cylindrical cylinder in which the upper peripheral wall is continuous with the lower peripheral wall without providing the concave surface. A hinge portion is formed along a predetermined inclined surface as a peripheral wall (not shown).
This embodiment differs from the previous embodiment only in that the shape of the spout is flattened by the increase of the arc radius, but the other effects are not changed at all.
[0013]
【The invention's effect】
The present invention has the following effects because it is configured as described above.
When the opening / closing lid is opened, the opening / closing lid has substantially the same shape as one arc-shaped peripheral wall, and the central part of the upper edge protrudes to serve as a liquid guide surface of the spout, so that the outflow direction of the content liquid is kept constant. At the same time, the content liquid can be reliably poured out to the end.
The opening / closing lid is opened and closed by a spring action centering on the hinge part, and is elastically engaged with the lip part, so that the spout can be closed during the pouring, so that dust in the air does not enter. it can.
Since the opening / closing lid is formed inside the container body, it does not come into contact with another container during transportation and is not deformed, thereby preventing an accident due to cutting of the broken portion.
