Description

The present invention relates to a middle plate raising type discharge container capable of recognizing the remaining amount of contents while suppressing deterioration of appearance.

There is known a discharge container in which the storage volume in the container decreases by the volume integral of the discharged contents as the contents in the container are discharged. For example, Patent Document 1 describes a discharge container provided with a sliding bottom lid slidably arranged in the body of the container. When the contents are discharged, the sliding bottom lid rises and the storage volume inside the container decreases.

JP-A-2010-173701

However, in such a medium plate raising type discharge container, in order to recognize the remaining amount of the contents, a see-through window portion in which the inside of the container body can be seen through may be formed in the body portion of the container body. The user recognizes that the remaining amount of the contents has decreased by visually recognizing the ascending and displaced sliding bottom lid through the see-through window portion. However, since the see-through window portion is formed on the body portion of the container body, there are problems that the appearance of the discharge container is deteriorated and the contents are not suitable for the contents requiring light shielding property.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a middle plate raising type discharge container capable of recognizing the remaining amount of contents while suppressing deterioration of appearance.

The present invention employs the following means in order to solve the above problems. That is, the middle plate raising type discharge container of the present invention is attached to a bottomed tubular container body in which the contents are housed, a stem supported so as to be movable downward in an upwardly biased state, and the upper end of the stem. It has a pressing head formed with a discharge hole for the contents, and is slidably fitted into the body of the container body with a pump mounted on the mouth of the body to discharge the contents. A middle plate that rises in the body portion, a plurality of ring bodies arranged in multiple rings on the bottom of the container body, and two ring bodies that are adjacent to each other in the radial direction intersecting in the vertical direction are connected to each other. A plurality of hinge bodies and a connecting body for connecting the ring bodies arranged on one of the innermost and outermost sides of the ring bodies in the radial direction to the middle plate are provided and integrally formed. The ring body, which is provided with a remaining amount display member which is a resin component and is arranged on the innermost and outermost sides of the plurality of ring bodies in the radial direction, is fixed to the bottom portion and one said one. The positions of the two hinge bodies connected to the ring body in the circumferential direction are different from each other, and the remaining amount of the contents that can be recognized by visually recognizing the ring body from the lower surface on the bottom portion. It is characterized in that a recognition unit is provided.

In the present invention, it is recognized through the remaining amount recognition unit formed on the bottom that a plurality of ring bodies that are sequentially pulled up with the discharge of the contents are separated from the bottom.
That is, when the contents in the container are discharged by using a pump, the inner plate is displaced upward, and the ring body connected to the inner plate via the connecting body among the plurality of ring bodies is the inner plate. With the ascending displacement of, it is pulled up and separated from the bottom. Then, when the inner plate is further displaced upward, the other ring bodies adjacent to the ring body in the radial direction are pulled up via the hinge body and separated from the bottom portion. In this way, the plurality of ring bodies are sequentially pulled up in the radial direction and separated from the bottom portion as the inner plate is displaced ascending. Then, the user recognizes the remaining amount of the contents by recognizing the ring body which is not pulled up and is still arranged on the bottom of the plurality of ring bodies through the remaining amount recognition unit provided at the bottom. .. This makes it possible to recognize the remaining amount of the contents while suppressing deterioration of the appearance of the container body as compared with the case where the remaining amount recognizing part is formed on the body portion of the container body.
Here, since the plurality of ring bodies, the plurality of hinge bodies, and the connecting body constituting the remaining amount display member are integrally formed of the resin material, the structure of the ring body and the hinge body may be replaced with, for example, paper. Compared to the case of adopting a band made of film and wound so as to exhibit a spiral shape, a separate member for fixing such a band to the bottom of the container body and the inner plate is required. Therefore, the remaining amount display member can be easily manufactured, and the remaining amount display member can be easily fixed to the bottom of the container body and the inner plate.
Further, since the structure of the ring body and the hinge body is made of resin, the ring body and the hinge body are stretched or twisted depending on the material used as compared with the above-mentioned band body made of paper or film. Can be suppressed. Further, since the remaining amount display member has a multiple annular structure and the ring bodies adjacent to each other in the radial direction are gradually pulled up, the shape of the structure to be used is different from that of the case where the remaining amount display member has a spiral structure. Due to the difference, it is possible to suppress the occurrence of stretching and twisting in the multi-annular structure. From the above, it is possible to suppress misidentification of the remaining amount of the contents.

Further, in the middle plate raising type discharge container of the present invention, each of the bottom portion may be separately formed with a support portion for supporting the portion of the ring body provided with the hinge body from the inside in the radial direction. ..
In this case, when the ring body is pulled up with the ascending displacement of the inner plate, it is possible to more reliably regulate the movement of other ring bodies that are radially adjacent to the ring body in the radial direction. As a result, it is possible to more reliably prevent misidentification of the remaining amount of the contents.

Further, in the middle plate raising type discharge container of the present invention, a second support portion that sandwiches the ring body in the radial direction may be formed on the bottom portion together with the support portion.
In this case, since the ring body before being pulled up is more reliably restricted from moving both inward and outward in the radial direction, it is possible to more reliably prevent misidentification of the remaining amount of the contents.

Further, in the middle plate raising type discharge container of the present invention, the ring bodies may be arranged concentrically.
In this case, when the plurality of ring bodies are sequentially pulled up, the force applied to the ring bodies tends to be uniform, and the pulling operation of the ring bodies becomes more stable. As a result, it is possible to more reliably prevent misidentification of the remaining amount of the contents.

Further, in the middle plate raising type discharge container of the present invention, the bottom portion may be fitted and fixed in the lower end portion of the body portion.
In this case, since the bottom, the middle plate, and the remaining amount display member can be assembled and then the assembly can be assembled to the body of the container, the middle plate raising type discharge container can be more easily manufactured.

According to the middle plate raising type discharge container according to the present invention, the ring body is sequentially pulled up and separated from the bottom portion as the middle plate moves up and displaces according to the discharge of the contents, so that the ring body is arranged on the bottom portion through the remaining amount recognition portion. By visually recognizing the ring body, the remaining amount of the contents is recognized while suppressing deterioration of the appearance of the container body as compared with the case where the remaining amount recognizing part is formed on the body of the container body. Is possible.

A method of using the middle plate raising type discharge container 1 having the above configuration will be described.
First, the pressing head 23 is pressed to lower the stem 22 with respect to the cylinder 25. As a result, the piston 24 descends in the cylinder 25 in a state where the communication hole 26A formed in the piston guide 26 is opened and the lower end opening 25A of the cylinder 25 is closed. As a result, the content C in the cylinder 25 is pressurized and discharged from the discharge hole 39A of the pressing head 23 through the communication hole 26A, the piston guide 26, and the stem 22.

After that, when the pressing of the pressing head 23 is released, the piston 24 rises in the cylinder 25 with the communication hole 26A closed and the lower end opening 25A of the cylinder 25 opened. That is, the piston 24 in the cylinder 25 is restored and moved upward in the cylinder 25 by the upward urging force of the urging member 28. As a result, the pressure inside the cylinder 25 becomes negative, and the content C contained in the liquid chamber 2A flows into the cylinder 25.
When the content C of the liquid chamber 2A flows into the cylinder 25, the content C in the liquid chamber 2A decreases, so that the liquid chamber 2A becomes a negative pressure. Therefore, the middle plate 4 is pulled up to the liquid chamber 2A side (upper side), and the sliding cylinder portion 45 rises while sliding in contact with the inner peripheral surface of the body portion 11. As a result, the volume of the liquid chamber 2A is reduced, and the pressure change occurring in the liquid chamber 2A is compensated. Here, since the liquid chamber 2A is hermetically sealed by the packing 37 and the sliding cylinder portion 45 of the inner plate 4, outside air does not flow into the liquid chamber 2A. Therefore, by raising the middle plate 4, the pressure change in the liquid chamber 2A is compensated without allowing outside air to flow into the liquid chamber 2A. As a result, the liquid chamber 2A is suppressed from being in a negative pressure state to maintain a good discharge operation, and the content C is prevented from being exposed to the outside air and deteriorated, for example.
