JPH0642972Y2 - Fixed-quantity discharge container with a pouring hole at the bottom - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fixed-quantity discharge container, and more particularly to a container in which an outlet is provided at the bottom and the container is used in an inverted state.

[Conventional technology]

Conventionally, the container is set upside down with the pouring hole facing down so that the contents with bottom fluidity can always be brought close to the pouring hole side so that the contents can be quickly discharged. Are variously provided.

As such a structure, there is, for example, one described in Japanese Utility Model Laid-Open No. 55-12492, and as shown in FIG. 4, a large diameter portion 22 is formed at the bottom of a bottom closing plate 21, and a container 20 is formed. It is designed so that it can be stood upside down.

Further, as a device in which the content in the container 20 is discharged by a fixed amount, there is one disclosed in Japanese Utility Model Laid-Open No. 58-23503. As shown in FIG. 5, a bellows-shaped push button 23 is provided on the side surface of the container 20, and by pushing the push button 23, the contents in the container 20 are discharged by a certain amount.

[Problems to be solved by the invention]

However, in the conventional device shown in FIG. 4, since the entire container is pressed to discharge the contents, the container must be easily deformable, and the contents will decrease. There is a problem that the container sometimes bends and the center of gravity moves, making it difficult to stand on its own.

On the other hand, if the structure as shown in FIG. 5 is adopted as the fixed amount discharging mechanism, the structure of the push button 23 becomes complicated and the integral molding becomes difficult.

Further, in each of the above publications, the pouring hole also serves as the filling hole, but in the inverted container, the contents are often mucus, and in such a case, the pouring hole is not always suitable for filling. In some cases, it was not possible to obtain a different shape, and the efficiency during filling had to be compromised to some extent.

The present invention has been made in view of the above matters, and can be stably placed in an inverted state and can discharge a certain amount of contents, and at the same time, molding is easy and filling of contents is also possible. It is a technical issue to make a fixed-quantity discharge container that is easy.

[Means for solving problems]

The present invention has the following configuration in order to solve the above technical problems.

That is, a bottom hole 2 of a container body 1 formed of a material and a thickness that is not easily deformed is provided with a pouring hole 3 and a bottom closing plate 4 for closing the pouring hole 3 in an openable and closable manner.

On the other hand, a filling hole 7 for filling the content 6 is formed in the top portion 5 of the container body 1, and after filling the content 6, the filling hole 7 is closed.

Further, a part of the side surface 8 of the container body 1 is made thin, and a dome-shaped convex portion 9 that can be elastically pressed is formed to obtain a fixed amount discharge container.

[Action]

According to the present invention, the container does not deform even when the contents are small, and the center of gravity does not move. Then, when the dome-shaped convex portion 9 which is made thin by making a part of the side surface 8 of the container body 1 thin and can be elastically pressed, only the dome-shaped convex portion 9 is deformed and a predetermined amount of the content 6 is discharged. It

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

A container body 1 made of a synthetic resin that is not easily deformed has a bottom portion 2 formed with a pouring hole 3 and a bottom closing plate 4 for opening and closing the pouring hole 3 via a three-point hinge 4a. Supported.

On the other hand, a filling hole 7 for filling the content 6 is formed in the top portion 5 of the container body 1. After filling the content 6 from here, the filling hole 7 is blocked. ing.

A part 8 of the side surface of the container body 1 is thin, and a dome-shaped convex portion 9 that can be elastically pressed is formed.

The container body 1 is manufactured by blow molding, but the dome-shaped convex portion 9 is formed by expanding a preform into a concave portion formed in a mold. Therefore, the dome-shaped convex portion 9 can be made thin without any special processing.

Therefore, the dome-shaped convex portion 9 can have elasticity and can be easily deformed by an external force.

In use, hold the container body 1 and use the bottom closure plate 4
Open. Subsequently, the dome-shaped convex portion 9 is pushed to push the contents 6
Is discharged.

The discharge amount in that case corresponds to the deformation amount of the dome-shaped convex portion 9, and a constant amount can always be discharged.

FIG. 3 shows another embodiment in which the filling hole 7 is closed by hot pressing so that a flat portion is not formed on the upper surface. Therefore, it is possible to prevent the container body 1 from being placed upright.

[Effect of device]

According to the present invention, the container can be placed in an inverted state, and even when the contents are reduced, the container body is not deformed and the center of gravity does not move, so that it is hard to fall down.

Further, the contents can be discharged in a fixed amount.

Further, it is easier to mold and can be manufactured at a lower cost as compared with the conventional fixed quantity container, and since the filling of the contents is performed through a dedicated filling hole, rapid filling is possible.
