The present invention relates to a fluid discharge container that is filled with fluid such as lotion or cosmetic liquid and discharges fluid to the outside by a discharge mechanism.

Conventionally, as a handy-type container filled with fluid such as skin lotion or cosmetic liquid, a container having an opening formed in the upper part, and a through hole provided in a closed state at the upper opening of the container A container is known that includes a formed lid and a discharge mechanism provided on the lid, and discharges the fluid filled in the container to the outside by the discharge mechanism.

However, in this container, it is difficult to discharge the fluid filled in the container to the end by the discharge mechanism, and the fluid may remain at the bottom of the container, resulting in waste of resources. In addition, every time the fluid filled in the container is discharged by the discharge mechanism, the fluid is replaced with external air, so that the fluid filled in the container may be kept in contact with the air and deteriorate.

Therefore, a bag-like inner container filled with a fluid inside, a female connector provided in the upper part of the inner container and formed with an insertion hole extending in the vertical direction, the inner container is accommodated, and an opening is formed in the upper part An outer container formed in a closed state at the opening of the upper part of the outer container, and a through-hole formed in the through-hole of the cover and into the insertion hole of the female connector A container has been proposed that includes a discharge mechanism that is inserted and provided with a male connector having a flow passage formed therein (see Patent Document 1).

According to this, it is easy to discharge the fluid filled in the inner container to the end by the discharge mechanism, and even if the fluid filled in the inner container is discharged by the discharge mechanism, the inside of the inner container is in a vacuum state or Since the state close | similar to it can be maintained, deterioration can be prevented, without the fluid with which the inner container was filled contacting air.

However, in the above-described container, when the bag-shaped inner container provided with the female connector is accommodated in the outer container in the manufacturing process, the outer surface of the female connector is in contact with the inner peripheral surface of the outer container. The structure was fixed by fitting into a container. For this reason, if the outer diameter of the female connector is larger than the inner diameter of the outer container, the female connector cannot be fitted into the outer container. On the other hand, if the outer diameter of the female connector is smaller than the inner diameter of the outer container, the female connector Since it is in an unstable state where it is not fixed to the outer container, the outer diameter of the female connector and the inner diameter of the outer container have to be exactly matched, and there is a problem that the design of the container becomes slightly difficult.

In addition, since the outer diameter of the female connector and the inner diameter of the outer container are exactly matched, the female connector must be completely vertical and fitted into the outer container with a strong force. There was a problem of becoming complicated.

Further, as described above, there is a problem that the shape and the diameter of the outer container are difficult to change due to the matching of the outer diameter of the female connector and the inner diameter of the outer container, and variations in container design are reduced.

Further, since a gap is generated between the lid and the female connector, it is difficult to insert the male connector into the insertion hole of the female connector unless the male connector of the discharge mechanism is completely penetrated through the through hole of the lid in the manufacturing process. Thus, there has been a problem that the assembly work becomes more complicated in the manufacturing process.

Also, there is a problem that the outer container becomes higher by the gap between the lid and the female connector and the container becomes larger.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a fluid discharge container that can be easily assembled and can be developed with a wide variety of designs.

According to this, since the female connector is mounted on the lower side of the lid in such a manner that the insertion hole and the through hole of the lid overlap each other in the axial direction, the upper end surface is in contact with the lower surface of the lid. The outer diameter of the container and the inner diameter of the outer container do not need to be exactly matched, and the container design is simplified.

Further, since it is not necessary to fit the female connector into the outer container and the female connector only needs to be attached to the lid, the container can be easily assembled in the manufacturing process.

Also, since it is not necessary to make the outer diameter of the female connector coincide with the inner diameter of the outer container, the shape and diameter of the outer container can be easily changed, and variations in container design can be increased.

Also, since there is no gap between the lid and the female connector, the male connector of the discharge mechanism can be easily inserted into the female connector in the manufacturing process, and the container can be assembled more easily in the manufacturing process.

Also, since there is no gap between the lid and the female connector, the container can be downsized, or the amount of fluid filling the inner container can be increased.

Further, it is preferable that the lid is provided with a fitting member that fits into the female connector on the lower surface. According to this, the female connector can be easily and reliably attached to the lower side of the lid.
