  The present invention relates to a liquid dispensing container and an inner stopper used therefor.

  In recent years, as a container for storing a liquid such as a cleaning liquid, a container having a trigger pump, that is, a liquid dispensing container for taking out a certain amount of cleaning liquid or the like by operating the pump by operating a lever has been proposed. This type of liquid dispensing container is usually configured so that the content liquid can be replenished when the amount of internal cleaning liquid becomes small. From the viewpoint of disposal, a package made of a soft resin sheet is often used.

When replenishing the liquid dispensing container with the content liquid, the trigger pump is removed from the container body. In general, since a dip tube is connected to the trigger pump, the surroundings are easily contaminated by the content liquid adhering to the dip tube.
In addition, when refilling the liquid dispensing container with the content liquid, from the viewpoints that the mouth of the liquid dispensing container has a small diameter and it is difficult to keep the liquid dispensing outlet of the refilling container open. , Skill is required for replenishment work.

Therefore, conventionally, in order to facilitate the replenishment of the content liquid into the liquid dispensing container, a liquid dispensing container in which the trigger pump can be removed with the dip tube remaining in the container body has been proposed. ing.
For example, Patent Literature 1 discloses a liquid ejector in which a cylindrical member having an injection window is fixed to an opening and neck portion by a locking piece, and a pipe for sucking liquid is extended below the cylindrical member. ing.
In Patent Document 2, a liquid injection window hole is drilled, and a hanging cylinder with a ridge around the inner surface is fixed to the neck of the mouth, and a suction pipe is suspended below the hanging cylinder. A container with a vertical pump is disclosed.
Patent Document 3 discloses a trigger type liquid ejection container in which a connecting member is fitted and fixed to a container body neck and a lower pipe is fitted and fixed to the connecting member.
Patent Document 4 discloses a container pump body in which a holder is attached to a mouth portion of a container body, and a suction pipe is attached to the holder.
Patent Document 5 discloses a pump replacement container in which a pipe holder for holding a content liquid suction pipe is attached to a container opening.

Conventionally, from the viewpoint of facilitating the replenishment operation, there has been proposed a container that can be replenished with the content liquid by inserting the nozzle of the liquid dispensing container into the liquid dispensing outlet of the replenishing container.
For example, Patent Document 6 discloses a container connector assembly including a spout member joined to a pouch container and a main body cap fixed to the bottle container.
In Patent Document 7, a nozzle receiving portion is provided in the pouch body, a pouch having a weak seal portion provided in the nozzle receiving portion, and a dispensing nozzle inserted into the nozzle receiving portion to open the weak seal portion are provided. A container is disclosed.

2B, the bottom wall 50 includes an annular bottom wall 53 that forms a first communication hole 52, and a belt-like bottom that extends radially from the annular bottom wall 53 toward the main wall 40. As shown in FIG. The wall portion 51 is used.

On the belt-like bottom wall portion 51, a support wall portion 60 protruding upward from the bottom wall portion 50 is provided inside the main wall portion 40 so as to surround the first communication hole 52. The support wall 60 has a substantially cylindrical shape whose axis is the same as the axis of the main wall 40, and the upper end surface of the support wall 60 is substantially horizontal. As shown in FIG. 2D, the height H <b> 2 on the bottom wall portion 50 of the support wall portion 60 is set lower than the height H <b> 1 of the main wall portion 40. That is, the support wall 60 has a shape in which the upper end of the support wall 60 does not protrude from the mouth 30 in a state where the inner plug 4 is fitted to the mouth 30 of the container body 3.
Below the support wall 60, a rectangular opening 62 communicating between the inside and outside of the support wall 60 is formed between the strip-shaped bottom walls 51.
In the main wall portion 40 of the inner plug 4, a region surrounded by the support wall portion 60 is a first flow path in the vertical direction, and a region surrounded by the support wall portion 60 and the main wall portion 40 is The second channel in the vertical direction is used. The first flow path and the second flow path are communicated in the horizontal direction by the opening 62.

  The bottom wall 50 is provided with a content liquid circulation pipe 54 extending downward from the annular bottom wall 53. As shown in FIG. 1, by inserting one end of the dip tube 6 into the content liquid circulation pipe 54, the first communication hole 52 and the dip tube 6 are connected in a liquid-tight manner.

Next, a method for replenishing the liquid into the liquid dispensing container 1 will be described.
First, the mounting cap 20 is unscrewed, and the extraction body 2 is removed from the container body 3. At this stage, the dip tube 6 remains in the container main body 3 together with the inner plug 4.
Next, a part of the content liquid replenishing container containing the replenishing content liquid is opened. An example of the content liquid replenishment container is a content liquid replenishment container 80 shown in FIG.
The content liquid replenishing container 80 is a bag main body 82 obtained by molding a flexible film and provided with a rectangular pouring member 84 protruding from a part thereof. In the middle of the dispensing member 84, a partition seal portion 86 that can be peeled off is provided.

  As shown in FIG. 4A, when the pouring member 84 is opened, the outer diameter D1 is smaller than the inner diameter d1 of the main wall portion 40, and the pouring member 84 is opened. The inner diameter D <b> 2 of the support wall 60 is larger than the outer diameter d <b> 2 of the support wall 60. Since the pouring member 84 has such a size, the pouring member 84 can be fitted into the support wall portion 60 and filled from the mouth portion 30 without overflowing the replenishment content liquid.

When the replenishment content liquid is replenished, as shown in FIG. 4A, a part of the dispensing member 84 of the content liquid replenishing container 80 is cut and opened to form a spout 88. Next, the spout 88 is opened, and the support wall 60 is inserted into the spout member 84. When the support wall portion 60 is inserted into the pouring member 84, the support wall portion 60 acts to widen the pouring member 84, peels off the partition seal portion 86, and forms a flow path for the replenishment content liquid in the pouring member 84. . And as shown in FIG.4 (b), it will be in the state by which the extraction | pouring member 84 and the support wall part 60 were fitted.
When the flow path is formed in the dispensing member 84, the replenishment content liquid in the bag main body 82 flows through the flow path and mainly flows into the support wall portion 60. Then, as shown in FIG. 2 (f), the replenishment content liquid flows into the support wall 60 in the flow of the arrow A, and then passes through the opening 62 and flows out of the support wall 60. The replenishing content liquid that has flowed out of the support wall portion 60 flows down through the second communication hole 56 and is replenished into the container body 3. Further, the air in the container body 3 is discharged out of the container body 3 through the second communication hole 56 as indicated by an arrow B.

Further, for example, the content liquid replenishment container 90 may be a content liquid replenishment container 90 as shown in FIG.
The content liquid replenishing container 90 is a bag main body 92 obtained by molding a flexible film and provided with a substantially cylindrical pouring member 94 protruding from a part thereof. The end surface of the dispensing member 94 is sealed with a thin film 96. As with the pouring member 84, the pouring member 94 has an outer diameter smaller than the inner diameter of the main wall portion 40 and an inner diameter larger than the outer diameter of the support wall portion 60.
In replenishing the content liquid, the thin film 96 of the content liquid replenishment container 90 is pressed against the support wall 60. Then, the thin film 96 is broken and the support wall 60 is inserted into the extraction member 94. Thus, the replenishment content liquid flows through the pouring member 94 and flows into the support wall 60. The replenishment content liquid that has flowed into the support wall 60 flows through the opening 62 and the second communication hole 56 in this order, and is filled in the container body 3.

Thus, the liquid pouring container of this embodiment can replenish the content liquid in a state in which the support wall portion and the pouring member are fitted. For this reason, it is possible to replenish the liquid dispensing container without overflowing the replenishing content liquid, and it is possible to replenish the content liquid while maintaining the dispensing outlet of the dispensing member in an open state.
Further, according to this liquid dispensing container, since the opening is formed in the support wall, the replenishment content liquid that has flowed into the support wall is quickly drained out of the support wall, and the replenishment content that has flowed out. The liquid can be filled into the container body from the second communication hole. That is, when the content liquid flows as indicated by an arrow A in FIG. 2 (f), the replenishment operation can be made much smoother than when the content liquid is replenished from the first communication hole.

  In the liquid dispensing container of the present embodiment, the dip tube is connected to the inner plug, and when the dispensing body is removed from the container body, the dip tube can be left in the container body. For this reason, the content liquid adhering to the dip tube does not stain the surroundings.
