Description

  The present invention relates to a container for packaging fluid, and more particularly to a handy-type container having a pump that discharges a predetermined amount of contents such as liquid cosmetics.

For example, as a handy type container for packaging liquid cosmetics such as skin lotion and cosmetic liquid, a bottomed cylindrical casing filled with liquid cosmetics, a lid attached to the upper end of the casing, a lid provided on the lid, In general, there is known a pump provided with a pump for discharging a predetermined amount of cosmetics (for example, see Patent Document 1 below).
However, in the case of the above-described container, if the cosmetics that are the contents are used up, the entire container is discarded, so that there is a problem in terms of the environment and a problem that the price is also high. In addition, in the above container, the contents filled in the casing cannot be discharged to the end by the pump, and the contents may remain at the bottom of the casing. Further, in the case of the above-described container, since the shape of the casing is limited to a cylindrical shape or a rectangular tube shape having the same cross section at all heights, there is a restriction in terms of design.

Therefore, as a means for solving the above problems, there is also a container that is used by inserting a bag filled with liquid cosmetics in a casing and then piercing the bag with a needle-like liquid absorption tube provided at the tip of the pump. It has been proposed (for example, see Patent Document 2 below).
According to this container, when the cosmetics in the bag are used up, it is only necessary to take out the bag from the casing and replace it with a new cosmetic packaging bag, and it is possible to repeatedly use components other than the bag, leading to a reduction in waste, In addition, it is economical because the consumer only needs to purchase a cosmetic packaging bag for replacement. In addition, in the container described above, the bag can be elastically deformed so that the content can be discharged to the end by the pump, and the shape of the casing constituting the appearance can be diversified.

However, with the replaceable container described above, it is difficult to pierce and connect the pump suction tube to the cosmetic-enclosed bag. In particular, when the container is a handy type, the bag needs to be small in size. Therefore, it is considered that the above work becomes more difficult.
Further, in the case of the above-described container, there is a possibility that the liquid cosmetic may scatter when the liquid absorption tube is inserted into the bag, and the liquid cosmetic may leak due to a crack in the bag.
Furthermore, in the container described above, there is a concern that the contents may be changed by air entering the bag when the liquid absorption tube is inserted into the bag or in the state where the liquid absorption tube is inserted into the bag, which is not preferable for hygiene.
JP 2006-44781 A Registered Utility Model No. 3001612

  The object of the present invention is as a handy-type container containing fluid such as liquid cosmetics, and can be used repeatedly for other components such as casings and pumps simply by changing the fluid-filled bag. The pump can be easily connected to the encapsulating bag, there is no risk of the contents splashing or leaking, and it is easy to use and effectively prevents the contents from being altered by contact with air. It is to provide what can be done.

  The container according to the present invention closes the vertical through hole by engaging with a bag filled with fluid therein, a female connector having a vertical through hole and fixed to the upper opening of the bag, and a lower end of the female connector. A cartridge comprising a plug, a substantially bottomed cylindrical casing for accommodating the cartridge, a lid detachably attached to the upper end of the casing, a fluid discharge pump provided on the lid, and a female connector extending downward from the pump The male connector has a fluid passage extending in the axial direction inside, and the male connector is a communication hole opened in the peripheral surface so as to communicate with the fluid passage near the lower end. The plug is pushed down at the lower end of the female connector so that the plug is released from the lower end of the female connector and the communication hole is a bag. It is one that is adapted to be made to face to.

The container of the present invention can be assembled, for example, by the following procedure (hereinafter referred to as “first assembly procedure”). That is, first, the male connector of the upper unit is inserted into the female connector of the cartridge from above. Then, the plug is pushed down at the lower end of the male connector, the plug is detached from the lower end portion of the female connector, and the communication hole formed near the lower end of the male connector is exposed in the bag. Next, the cartridge integrated with the upper unit by the above operation is accommodated in the casing, and a lid is attached to the upper end portion of the casing. Thus, the assembly of the container is completed, and the fluid as the contents can be discharged by the pump and used.
The container is also assembled by the following procedure (hereinafter referred to as “second assembly procedure”). That is, first, the cartridge may be accommodated in the casing, and then the male connector of the upper unit may be inserted into the female connector of the cartridge from above, and then the lid may be attached to the upper end of the casing.
When the fluid in the bag is used up, the lid is removed from the casing, and the cartridge integrated with the upper unit is removed from the casing. Next, after the male connector of the upper unit is pulled out from the female connector of the cartridge, it may be replaced with a new cartridge in which the fluid is sealed according to any one of the assembly procedures described above.
That is, according to the container of the present invention, if only the cartridge whose main component is a bag in which a fluid is sealed is replaced, the casing and the upper unit can be used repeatedly, leading to a reduction in waste. Economical. Moreover, according to the container of the present invention, since the connection of the upper unit to the cartridge is performed exclusively by inserting the male connector into the female connector, the operation is easy, and the contents are scattered at that time. There is no risk of leakage, and it is easy to use. Furthermore, since the ingress of air into the bag is effectively prevented, the contents are not likely to change in quality and are hygienic. In particular, in the case of the container according to the present invention, the overall configuration of the apparatus is simple and the connection of the upper unit to the cartridge is easy, so that the entire apparatus can be miniaturized and fluids such as liquid cosmetics can be packaged. It can be suitably used as a handy type container.

  As a preferred embodiment (first embodiment) of the container according to the present invention, the first outer convex portion is formed on the outer peripheral surface of the female connector, the cartridge is placed on the inner peripheral surface of the casing, and the lower end thereof is the bottom of the casing. A cartridge holding portion that receives the first outward projection is formed so as to be held at a position in contact with the wall or at a higher position.

According to the said 1st aspect, there exists a merit when assembling the container of this invention according to a 2nd procedure especially. That is, when the cartridge is accommodated in the casing, the cartridge is held at a position where the lower end of the cartridge is in contact with the bottom wall of the casing or higher than the first outer convex portion is received by the cartridge holding portion. Therefore, there is no possibility that the position of the female connector is shifted when the male connector is inserted from above, and the insertion work is facilitated.
Further, according to the first aspect, even when the container is assembled according to the first procedure, there is no risk that the cartridge bag is inadvertently pressed when the lid is attached to the casing, and the operation can be safely performed. There are benefits.

The first outer convex portion is usually formed on the outer peripheral surface of the portion of the female connector that protrudes upward from the upper opening of the bag, and the shape thereof is an annular shape that extends over the entire circumference of the outer peripheral surface. A plurality of them may be formed at intervals.
The cartridge holding portion is usually formed of an annular step formed upward on the inner peripheral surface of the casing, but is formed with an annular inward convex portion formed on the inner peripheral surface of the casing or spaced in the circumferential direction. It is also possible to configure with a plurality of inward convex portions.

  In the first aspect, more preferably, the second end of the outer peripheral surface of the female connector is in a position below the first outer convex portion and the tip is in contact with the inner peripheral surface of the casing or the inner side surface of the cartridge holding portion. The outward convex part is formed.

In the above case, the position of the cartridge accommodated in the casing is less likely to occur when the tip of the second outward projection comes into contact with the inner peripheral surface of the casing or the inner surface of the cartridge holding portion. When the container of the present invention is assembled according to the above procedure, the operation of inserting the male connector into the female connector is further facilitated, and the cartridge is held in a stable state in the casing during use.
The second outward convex portion is also generally formed at a position below the first outward convex portion on the outer peripheral surface of the portion protruding upward from the upper opening of the bag in the female connector, and the shape thereof. Is formed in an annular shape over the entire circumference of the outer peripheral surface, but a plurality of them may be formed at intervals in the circumferential direction.
In addition, the object with which the tip of the 2nd outward convex part touches is decided according to the structure of the casing side, for example, when the cartridge holding part consists of an annular step formed upward on the inner peripheral surface of the casing, The tip of the second outward projection comes into contact with the inner peripheral surface of the lower part of the casing than the annular step.

  As another preferred embodiment (second embodiment) of the container according to the present invention, an outer convex portion that is received by the upper end surface of the casing is formed on the outer peripheral surface of the female connector, and the casing is at its upper end surface. By receiving the outward convex portion of the female connector, the cartridge may have a height that can hold the cartridge at a position where the lower end of the cartridge is in contact with or higher than the bottom wall of the casing.

According to the second aspect, as in the case of the first aspect, when assembling the container of the present invention according to the second procedure, there is no possibility that the position of the female connector is shifted when the male connector is inserted from above. There is a merit that the insertion operation becomes easy and there is no risk that the bag of the cartridge will be inadvertently pressed when the lid is attached to the casing when the container is assembled according to the first procedure, and the operation can be safely proceeded. . In addition, in the case of the second embodiment, the casing size can be further reduced.
The outward convex portion is usually formed on the outer peripheral surface of the portion of the female connector that protrudes upward from the upper opening of the bag, and the shape thereof is an annular shape over the entire circumference of the outer peripheral surface. A plurality of them may be formed.

In the second aspect, compared to the first aspect, the contact area between the outer convex portion of the female connector and the casing portion that receives the outer convex portion, that is, the upper end surface of the casing can be increased. It can be said that the stability of the cartridge in the casing is relatively high.
However, as in the case of the first aspect, a second outer convex portion whose tip is in contact with the inner peripheral surface of the casing is further formed at a position lower than the outer convex portion on the outer peripheral surface of the female connector. It may be. In this case, since the tip of the second outer convex portion is in contact with the inner peripheral surface of the casing, displacement of the cartridge accommodated in the casing is less likely to occur. Therefore, the container of the present invention is removed according to the second procedure. When assembling, the operation of inserting the male connector into the female connector is further facilitated, and the cartridge is held in a more stable state in the casing during use.

In the container according to the present invention, screw means are preferably used as means for attaching the lid to the upper end of the casing.
The screw means includes, for example, a male screw formed on the upper end portion of the casing and a female screw formed on the lid, but may be reversed.

When screw means are used as the means for attaching the lid, particularly when the container of the present invention is assembled in accordance with the second procedure, a specific effect can be obtained. That is, after the cartridge is stored in the casing, if the lid is screwed into the upper end of the casing, the male connector is inserted into the female connector, so that it takes less time to connect the connectors, and the workability is further improved. And usability is improved.
The attachment means is not limited to the screw means as long as the lid is detachably attached to the upper end of the casing.
