Description

  The present invention relates to a container for a liquid such as a sauce, and more particularly to a liquid dispensing container having a highly viscous content liquid and a dual overcap that can be used for a low viscosity content liquid.

  As a container for storing highly viscous items such as sauces, a nozzle member is erected at the mouth of the container, and when dispensing, the content liquid is poured out from the nozzle outlet by pressing the container body, and the pressure is released. A liquid dispensing container in which the body part of the container is restored when the liquid is contained and the content liquid in the nozzle member is sucked into the container so that the liquid does not drip outside from the nozzle outlet is known. (See Patent Document 1).

The container described in Patent Document 1 is used as a container such as a liquid seasoning.
However, in the case of a liquid with low viscosity, it is possible to pour the content liquid simply by tilting the container. Therefore, if a thin nozzle is provided, the nozzle can be used for smooth dispensing of the content liquid. It was necessary to provide an air inlet separately from the spout of the member.

  However, for content liquids with different viscosities, prepare an overcap for each content liquid, and select one of multiple types of overcaps according to the viscosity of the content liquid to be filled in the container. It was necessary to adhere to the container.

  For this reason, when the same kind of containers with different viscosities are filled, there is a problem that a plurality of types of overcaps must be prepared according to the type of the contents liquid.

  An object of the present invention is to solve the above problems, and to provide a liquid dispensing container having an overcap that can be used for both a high-viscosity content liquid and a low-viscosity content liquid. To do.

In order to solve the above-mentioned problems, the present invention provides a liquid dispensing container, a container whose body can be deformed by being pressed , an inner plug that fits into the mouth tube of the container, and an upper part of the container. The overcap is a cap base composed of an upper wall and a side wall, and an open / close attached to the cap base via a hinge. is composed of a lid, the wall upper surface on the cap base has an upper end the pouring cylinder to form a flow path cross-sectional area as the suction force is generated by restoring to its original shape when the body portion is deformed standing the conical tubular is continuously provided on the upper end of the pouring cylinder has become a spout spout lip warped outwardly is formed on the periphery, the connecting portion between the conical tube and the pouring cylinder It has an opening, to adopt a configuration wherein the air inlet tube is vertically .

  As a specific configuration of the center portion of the upper wall, an opening is provided in the center of the upper wall of the cap base body, a fitting cylinder that fits into the inner periphery of the inner plug is provided along the periphery of the opening, and the conical cylinder is the opening. The structure characterized by being continuously arranged so as to cover.

  By forming an air introduction tube at one corner of the overcap small-diameter dispensing cylinder, the container with the overcap attached can be used also for liquid contents having different viscosities.

Next, the liquid dispensing container of the present invention will be described with reference to the drawings.

The container A is a container formed of synthetic resin, and includes a mouth tube part 1, a shoulder part 2, a body part 3, and a bottom part 4.
On the outer periphery of the upper end of the mouth tube portion 1 of the container A, a fitting ridge 5 and a neck ring 6 are projected.
The cross section of the shoulder portion 2 and the body portion 3 is a square shape with the corners being arcs, and the lower portion 2a of the shoulder portion 2 has a large inclination, and the lower end thereof has a fitting recess 7 over the entire circumference. Is formed.

  The inner stopper B includes an outer cylinder 8 fitted to the outer periphery of the mouth tube portion 1 of the container A, an inner tube 9 fitted to the inner periphery of the mouth tube portion 1 of the container A, and an annular upper wall 10. At the inner bottom end of the tube 8, a locking ridge 11 is provided to be fitted with the fitting ridge 5 of the mouth tube portion 1 when the inner plug B is plugged into the mouth tube portion 1 of the container A. ing.

The inner cylinder 9 is fitted and inserted into the inner periphery of the container mouth cylinder portion 1, and a partition wall 12 is continuously provided at the lower end thereof.
The partition wall 12 is formed with a cut groove 13 having a fixed shape, and the inside thereof is a removal portion 14 that forms an outlet for the content liquid. The upper surface of the removal portion 14 is pulled through a connecting piece. A ring 15 is provided continuously.

The overcap C includes a cap base C1 and an opening / closing lid C2 attached to the cap base C1 by a hinge.
The cap base body C <b> 1 includes a rectangular upper wall 20 and a side peripheral wall 21 that is connected to the periphery of the upper wall 20.
An opening 22 is formed in the central portion of the upper wall 20, and a fitting cylinder 23 that is fitted to the inner peripheral surface of the inner cylinder 9 of the inner plug B is suspended from the periphery thereof.

A conical cylinder 24 that covers the opening 22 and extends upward is provided on the upper surface of the upper wall 20, and a pouring cylinder 25 is erected at the center upper end of the conical cylinder 24.
The upper end of the dispensing cylinder 25 is a spout, and a spout lip 26 is formed on the periphery.
An air introduction pipe 27 is suspended from a connection portion between the conical cylinder 24 and the dispensing cylinder 25.
At the lower end of the side peripheral wall 21, a locking ridge 28 is provided that fits into the fitting recess 7 formed in the container A.

  A hinge 29 is provided at one end edge of the upper wall 20, and a locking recess 30 is provided at the edge of the upper wall 20 opposite to the hinge 29.

The opening / closing lid C <b> 2 includes a top wall 31 and a side wall 32, and one side wall 32 is connected to the hinge 29.
At the center of the back surface of the top wall 31, there is provided a plug 33 that fits into the inner surface of the extraction tube 25 and seals the outlet.
A knob 34 that engages with the locking recess 30 of the upper wall 20 is disposed on the side wall 32 on the opposite side of the hinge 29.

Next, usage modes and effects of the container of this embodiment will be described.
The container A is filled with a liquid seasoning such as tonkatsu sauce, medium-concentrated sauce, or Worcester sauce as the content liquid.
After filling the content liquid, the inner stopper B is fitted into the mouth tube portion 1 of the container A by stoppering.

Thereafter, the overcap C is again attached to the container A, and the opening of the container A is completed.

In dispensing the content liquid, if the content liquid is highly viscous, the body 3 is pressed and poured out.
When the pressure is released, the body part 3 is restored, and the liquid in the dispensing cylinder 25 is sucked into the container A to prevent dripping. The container A is kept upright after the dispensing.

When the content liquid has a low viscosity, the content liquid is poured out by tilting the container A, and the pouring is stopped by returning it to the original state.
In dispensing, even if the diameter of the dispensing cylinder 25 is small, the air is introduced from the air introduction pipe 27, so that the dispensing is easy.
When the dispensing is stopped, the dripping can be prevented by the dispensing lip 26 of the dispensing cylinder 25.

  By forming an air introduction tube at one corner of the overcap dispensing tube, the container with the overcap can be used for both high-viscosity liquid and low-viscosity liquid.

It is a sectional elevation view before opening of the liquid pouring container of the present invention. It is a sectional elevation view at the time of use of a liquid pouring container.
