Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a content liquid dispensing container, and more particularly, to a stopper punching mechanism for a bottom wall of a middle plug of a content liquid dispensing container.
[0002]
[Prior art]
Cut and cut the plug part of the bottom wall of the inner plug into a container fitted with a bottomed inner plug at the container mouth, and insert the liquid outlet tube into the inner tube of the inner plug, so that the liquid content can be removed. Conventionally, a content liquid dispensing container that is adapted to be dispensed through a liquid outflow passage provided in a lead-out cylinder has been known.
[0003]
[Problems to be solved by the invention]
In the conventional dispensing container, cutting of the plug portion of the inner plug bottom wall is performed by piercing and pushing a cutting blade provided at the tip of the liquid outlet tube around the plug portion.
However, since the conventional one has only one cutting blade, there is a problem that the liquid lead-out cylinder is inclined when the cutting blade is pierced and the punching becomes unstable.
[0004]
In addition, when there was a single cutting blade, the portion that remained without being cut near the end of the cutting was bent, and the plug portion remained in the container while being connected to the bottom wall of the inner plug. For this reason, there has been a problem in that the connecting portion between the stopper and the bottom wall blocks the content liquid outflow hole to reduce the flow rate of the content liquid.
[0005]
The present invention aims to solve the above problems, without the cutting blade tilting,
It is an object of the present invention to provide a plug stopper punching mechanism that is in contact with the bottom wall of the inner plug, reliably cuts the periphery of the stopper portion of the bottom wall, and completely separates the stopper portion from the inner plug.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention includes, as a liquid dispensing container, an inner stopper fitted into the container and the container mouth, and a support stand provided with a liquid outlet tube inserted into the inner stopper. The inner stopper includes an outer cylinder and an inner cylinder, and the inner cylinder has an upper cylinder portion fitted to the inner periphery of the container mouth portion, and a reduced diameter seal below the inner cylinder portion. The bottom of the seal cylinder is connected to the bottom wall provided with a thin wall portion. The liquid outlet cylinder has a groove-shaped liquid outflow path extending in the longitudinal direction on the outer circumference of the cylinder. The inner circumference of the cylinder is an air inflow path, and a configuration characterized by comprising a plurality of cutting blades arranged at equal intervals at the tip of the cylinder is adopted.
[0007]
As an example of the cutting blade, the cutting blade has a double-edged configuration.

[0010]
As shown in FIG. 3, the support base C includes a support plate 20, a liquid lead-out cylinder 21 erected at the center of the support plate 20, and a support rod 22 of the container A erected at the periphery of the support plate 20. It has.
In the support plate 20, an opening 23 is drilled between the liquid lead-out cylinder 21 and the support rod 22, and a support piece 24 is suspended from the lower surface of the support plate 20 corresponding to the support rod 22.
[0011]
The inside of the liquid lead-out cylinder 21 is an air inflow passage 25, and a partition wall 27 having an air inflow hole 26 is continuously provided near the upper end.
Two cutting blades 28 and 29 arranged at symmetrical positions project from the upper end of the liquid lead-out cylinder 21.
The lower part of the outer periphery of the liquid outlet cylinder 21 is an enlarged diameter part 30, and a plurality of longitudinal grooves 32 extending to the support plate 20 are formed at equal intervals on the surface to form a liquid outflow path 31. ing.
[0012]
The use mode and operational effects of the container of the present invention will be described.
After filling the container A with the content liquid, the inner stopper B is stoppered, and the container A and the support base C are commercially available as a set.
[0013]
At the time of use, the stopper 17 of the bottom wall 15 of the inner stopper B is cut and the liquid outlet tube 21 of the support base C is inserted into the inner stopper B, the support base C is attached to the container A, and the container A and the support base C are inserted. Is placed in a required place, and a small amount of liquid is poured out through a liquid outflow passage 31 provided with a liquid outlet cylinder 21 on the outer periphery.
[0014]
When cutting the bottom wall 15 of the inner plug B, as shown in FIG. 4, the tip of the liquid outlet cylinder 21 of the support base C is fitted into the inner cylinder 11, and the cutting blades 28 and 29 are inserted into the thick plug of the bottom wall 15. When the cutting blades 28 and 29 are pushed along the cutting groove 18 by holding the support base C and then pushing the cutting blades 28 and 29 into the cutting groove 18, the thick plug portion 17 of the bottom wall 15 is thinned. 16 is separated.
