Description

  The present invention relates to a liquid discharge container provided with a pump for discharging various liquids such as cosmetics in appropriate amounts.

  This type of conventional container is used as a container for cosmetics and shampoos, but generally has only one liquid storage chamber (Patent Document 1). For this reason, for example, when used as a container for cosmetics, since only one cosmetic can be accommodated in one container, the same number of containers as the type of cosmetics to be used is required. It was extremely inconvenient because it was necessary to always carry a plurality of containers.

  In order to eliminate this inconvenience, conventionally, two storage bags storing different liquids are respectively stored in the storage case in a storage case having a storage section divided into two parts. It has been proposed to stab each tube into the storage bag and simultaneously operate the pump unit to take out two types of liquids (Patent Document 2).

  However, in the configuration using the above-described two storage bags, in order to increase the storage capacity of the liquid, the storage bag must have a large capacity, and the case for storing the storage bag becomes even larger, which is portable. As such, there is an inconvenience that it is not easy to use. The present invention eliminates this inconvenience and does not use a storage bag, so that even if the amount of a plurality of types of liquid stored in the case is increased, the size of the case is not greatly affected, and the liquid discharge container is easy to use. The purpose is to provide.

In order to achieve this object, the liquid discharge container according to claim 1 of the present invention has two liquid storage chambers partitioned liquid-tightly, and each of the liquid storage chambers is provided with a pump separately. each pump includes a vertically movable drive head provided to each pump, provided with a discharge nozzle provided in each drive head, out Ki吐 before provided to the drive head in response to vertical movement of the respective drive heads In order to discharge the liquid in the liquid storage chamber from the nozzle, an operating arm is provided so as to extend over and engage with the center of the upper surface of each driving head, and the operating arm can be moved up and down. The arm is supported by a support shaft that can be tilted in the direction of each driving head. When the center of the operating arm is pushed down, the two driving heads are lowered at the same time, while one end side of the operating arm is pushed down. Only the corresponding driving head and is one that was configured to descend.

Similarly, in order to achieve the above object, according to a second aspect of the present invention, in the liquid discharge container according to the first aspect, each discharge nozzle is provided detachably with respect to the drive head and has a different discharge port diameter. It is provided to be exchangeable with the discharge nozzle .

According to the liquid discharge container according to claim 1 of the present invention, a plurality of kinds of liquids can be selectively discharged from one container at the same time or separately, so there is no need to carry a plurality of containers. In addition to being easy to use and easy to use, the operation of selectively discharging multiple types of liquids simultaneously or separately from one container is extremely simple and reliable using only one hand holding the container. There is an effect that can be achieved.

Further, according to the liquid discharge container of the second aspect of the present invention, in addition to the effect of the first aspect, it is possible to mount a discharge nozzle having a discharge port size of a size corresponding to the viscosity of the stored liquid. since, there is an effect that irrespective always reliable and smooth discharge operation of the viscosity of the contained liquid is Ru made.

Hereinafter, a reference example of the present invention will be described. As shown in FIGS. 1 to 3, the liquid discharge container 1 includes a container body 10 having a substantially cylindrical shape and a small upper part, and the container body 10 has a partition wall. 11 includes two liquid storage chambers 12 a and 12 b that are liquid-tightly partitioned by 11. The opening bottom of the container body 10 is liquid-tightly closed by a bottom lid 13, and a pump mounting body 15 is attached to the small diameter portion of the container body 10 via a packing 14 installed on the top surface. . A cover 16 is detachably fitted to the pump attachment body 15.

  Mounting cylinders 15a and 15b project from the upper surface of the pump mounting body 15 so as to correspond to the liquid storage chambers 12a and 12b, respectively, and the liquids filled in the liquid storage chambers 12a and 12b are respectively supplied to the mounting cylinders 15a and 15b. Pumps 20a and 20b for discharging the liquid discharge container 1 from the liquid discharge container 1 in appropriate amounts are attached and fixed. The fitting cylinders 31a and 31b of the drive head 30 are fitted to the lifting cylinders 21a and 21b located at the upper ends of the pumps 20a and 20b. The lower end of the outer peripheral surface of the drive head 30 is in contact with the inner peripheral surface of an annular guide wall 17 that is integrally provided upright on the upper surface of the pump mounting body 15.

  As shown in FIGS. 1 and 2, a pair of front and rear restricting plates 32a and 32b hanging from the inner surface of the top plate are integrally projected on the drive head 30, and each of the restricting plates 32a and 32b is driven by the drive. When the head 30 is lowered from the standby state (shown state), the head 30 is formed so as to be in sliding contact with the pair of front and rear guide plates 33a and 33b provided upright on the upper surface of the pump mounting body 15. The restriction plates 32a and 32b and the guide plates 33a and 33b constitute a restriction mechanism.

  As shown in FIGS. 2 and 4, the discharge nozzles 40a and 40b are removably attached to the mounting cylinder 34 (only the fitting cylinder 31a is shown) communicating with the fitting cylinders 31a and 31b of the drive head 30. Yes. That is, these discharge nozzles 40a and 40b can be replaced separately, and those having an appropriate diameter are selected and used according to the viscosity of the liquid stored in each liquid storage chamber 12a and 12b.

  Here, the configuration of the pumps 20a and 20b will be described in detail with reference to FIG. 1. Since each pump has the same configuration, only the pump 20a will be described, and for the pump 20b, a is replaced with b as a corresponding component. Stop with the sign. The elevating cylinder 21a is supported by the mounting cylinder 15a so as to be movable up and down, the lower part is thin and a step is formed, and the coil spring 23a disposed between the lower surface of the step and the annular bucket 22a is elastically moved upward. On the other hand, the upper surface of the stepped portion of the elevating cylinder 21a is engaged with the lower surface of the upper end inner peripheral projecting edge of the mounting cylinder 15a to restrict the movement in the upward direction.

  The bucket 22a is disposed on the protruding edge portion of the operating rod 25a disposed in the upper end large diameter portion of the substantially cylindrical housing 24a. When the elevating cylinder 21a is lowered, the bucket 22a is elastically biased downward by the coil spring 23a. The operating rod 25a is also elastically biased downward by the coil spring 23a through the bucket 22a. The upper end of the housing 24a is fitted and fixed to the mounting cylinder 15a. A valve seat 26a is provided on the lower inner surface of the housing 24a, and a ball valve 27a is disposed on the valve seat 26a.

  The upper end of the introduction pipe 28a is fitted and fixed to the lower end portion of the housing 24a than the valve seat 26a, and the lower end of the introduction pipe 28a is positioned close to the bottom lid 13. A coil spring 29a is disposed between the ball valve 27a and the lower surface of the projecting edge portion of the operating rod 25a. In the standby state shown in FIG. 1, the ball valve 27a is elastically biased downward, and the operating rod 25a is moved downward. The bullet is energized upward. The elastic urging force of the coil spring 29a is set to be weaker than the elastic urging force of the coil spring 23a, and the ball valve 27a is kept closed in the standby state shown in FIG.

Next, the operation of the reference example described above will be described. When the liquid storage chambers 12a and 12b are filled with different types of liquids (not shown) in an initial standby state (see FIG. 1), when the cover 16 is removed and the drive head 30 is pushed down, each lifting cylinder 21a and 21b are also lowered, and the buckets 22a and 22b and the operating rods 25a and 25b are also lowered by the elastic biasing force of the coil springs 23a and 23b. At this time, the regulation plates 32a and 32b are in sliding contact with the corresponding guide plates 33a and 33b to guide the drive head 30 so as to move vertically without shaking back and forth, so that the drive head 30 is pushed down vertically. In accordance with the amount of depression, the elevating cylinders 21a and 21b are lowered by the same distance without deviation.

  As a result, the pressure in each of the elevating cylinders 21a and 21b increases, and the pressure in the space below the projecting edge of the operating rods 25a and 25b in the housings 24a and 24b increases. This pressure causes the operating rods 25a and 25b to The liquid in the space below the protrusion starts to move from the protrusion to the space above through the gap between the buckets 22a and 22b and the housings 24a and 24b.

  Further, when the drive head 30 is pushed down to reach the lowest lowered position where the lower ends of the fitting cylinders 31a and 31b are in contact with the upper end surfaces of the mounting cylinders 15a and 15b, the lowering is prevented. In this state, the pressure on the liquid in the housings 24a and 24b becomes maximum, and the liquid is discharged from the discharge nozzles 40a and 40b together with the liquid in the elevating cylinders 21a and 21b.

  Here, when the push-down force applied to the drive head 30 is released, the coil springs 23a, 23b, 29a, 29b return to their original positions due to the resilient force of the coil springs 23a, 23b, 29a, 29b, and enter a standby state. At this time, the pressure in each of the housings 24a, 24b is reduced to the liquid storage chambers 12a. 12b, the ball valves 29a and 29b are opened, and the liquid storage chambers 12a. The liquid 12b flows from the introduction pipes 28a and 28b, and is ready for the next operation.

Then, the 2nd reference example regarding the discharge nozzle of this invention is demonstrated based on FIGS. As shown in FIG. 5, the pair of discharge nozzles 50 a and 50 b are integrally connected by a connecting member 51. A pair of locking claws 52a and 52b are provided on the back side of the connecting member 51, and these locking claws 52a and 52b can be displaced in the approaching direction to each other and can be returned to their original positions. On the other hand, as shown in FIG. 6, the drive head 53 is provided with mounting cylinders 54a and 54b for removably attaching the discharge nozzles 50a and 50b, and the engaging claws 52a and 52b are removably inserted. A locking hole 55 to be stopped is provided.

In the present reference example , the locking claws 52a, 52b are positioned corresponding to the locking holes 55 in a state where the locking claws 52a, 52b are retracted toward each other, and the discharge nozzles 50a, 50b are positioned corresponding to the mounting cylinders 54a, 54b. By pushing, the discharge nozzles 50a and 50b can be attached to the mounting cylinders 54a and 54b in a state where the back side of the connecting member 51 is in contact with the front flat portion of the drive head 53 (see FIG. 7). In this attached state, the locking claws 52a and 52b are resiliently returned to their original positions and are prevented from coming out of the locking holes 55. On the other hand, when each of the discharge nozzles 50a and 50b is pulled out with a predetermined force or more, the locking claws 52a and 52b are squeezed in the approaching direction to be separated from the locking hole 55, and the discharge nozzles 50a and 52b are removed. 50b can also be detached from the mounting cylinders 54a and 54b at the same time.

Next, a reference example including three liquid storage chambers as a third reference example of the present invention will be described with reference to FIGS. As shown in FIG. 8, the liquid discharge container 2 includes a container main body 60 having a substantially cylindrical shape and a small diameter at the top, and the container main body 60 includes three partition walls provided with a central angle of approximately 120 degrees. There are three liquid storage chambers 62 (only one shown) that are liquid-tightly divided by 61 (only one shown). The bottom surface of the container body 60 is liquid-tightly closed by a bottom lid 63, and a pump mounting body 65 is mounted on the small diameter portion of the container body 60 via a packing 64 installed on the top surface. . A cover 66 is detachably fitted to the pump attachment body 65.

  A mounting cylinder 65a (only one is shown) projects from the upper surface of the pump mounting body 65 corresponding to each liquid storage chamber 62, and each mounting cylinder 65a is a peripheral wall projecting from the upper surface of the pump mounting body 65. 67 and a trifurcated partition wall 68. Each partition wall 68 is positioned corresponding to each partition wall 61. A pump 70 (only one is shown) for discharging an appropriate amount of liquid filled in each liquid storage chamber 62 to the outside of the liquid discharge container 2 is fixedly attached to each mounting cylinder 65a. Since the configuration of these pumps 70 is the same as that of each of the pumps 20a and 20b described above, description thereof is omitted.

  The lifting cylinder 71 of each pump 70 is fitted with a fitting cylinder 81 (only the driving head 80a is shown) of the driving heads 80a, 80b, and 80c. These drive heads 80a, 80b, and 80c are substantially fan-shaped in plan view, and are formed with recesses for hooking fingers when they are pushed down to the center. Each of the drive heads 80a, 80b, and 80c is integrally formed with discharge nozzles 82a, 82b, and 82c that communicate with the fitting cylinder 81 so as to protrude from the upper end of the front surface formed in a flat shape. They are installed at an interval of approximately 120 degrees in the horizontal direction.

In this reference example, when the drive heads 80a, 80b, and 80c corresponding to the liquid storage chamber 62 that stores the liquid to be discharged are pushed down with the cover 66 removed, the above-described pumps 20a and 20b are pressed. Similarly to the above operation, the pump 70 corresponding to the pushed-down drive heads 80a, 80b, 80c operates, and a desired liquid can be discharged from the discharge nozzles 82a, 82b, 82c.

In this reference example , a plurality of drive heads 80a, 80b, and 80c can be simultaneously pushed down, but the liquid discharge directions from the discharge nozzles 82a, 82b, and 82c are spaced 120 degrees apart. Therefore, it is difficult to receive this with the same container or palm, and actually it is operated separately. In this reference example , the discharge nozzles 82a, 82b, and 82c are provided integrally with the corresponding drive heads 80a, 80b, and 80c, and therefore cannot be replaced with ones having different diameters.

Subsequently, the implementation form of the present invention will be described with reference to FIGS. This embodiment is different from the first reference example shown in FIGS. 1 to 4 in that a drive head is provided for each pump, and an operating arm is provided so as to extend to the central portion of both drive heads. By the way. As shown in FIGS. 10 and 11, the liquid discharge container 3 has two liquid storage chambers 92 a and 92 b in which the inside of the container body 90 is liquid-tightly divided by a partition wall 91, and a mounting cylinder for the pump mounting body 93. 93a and 93b are located away from the peripheral edge, and a support cylinder 94 protruding upward from the mounting cylinders 93a and 93b is integrally provided therebetween.

On the other hand, the drive heads 95a and 95b are provided for the pumps 96a and 96b attached and fixed to the mounting cylinders 93a and 93b, respectively. An operating arm 97 is stretched over the upper surfaces of the drive heads 95a and 95b so as to reach the central portion thereof, and the operating arm 97 is supported on a support cylinder 94 by a support shaft 98. The support shaft 98 is made of a flexible material such as a synthetic resin, and is formed in a thin shape in which the surfaces of the portions projecting from the support cylinder 94 on the side of the drive heads 95a and 95b are cut off. ing. For this reason, the support shaft 98 can be easily tilted in the direction of the drive heads 95a and 95b. The drive heads 95a and 95b are integrally provided with discharge nozzles 99a and 99b and extend in the approaching direction. Since other configurations are the same as those of the first reference example , description thereof is omitted.

  In the present embodiment, when the center of the operating arm 97 is pushed down, the two drive heads 95a and 95b are simultaneously lowered, the pumps 96a and 96b are operated, and the liquids in the liquid storage chambers 92a and 92b are discharged from the discharge nozzles, respectively. It discharges toward the direction which mutually approaches from 99a, 99b. Therefore, two kinds of liquid can be reliably received even in a narrow part such as a palm. On the other hand, when one end side of the operating arm 97, for example, the side corresponding to the drive head 95b is pushed down, only the corresponding drive head 95b is lowered, and only the liquid in the liquid storage chamber 92b is discharged from the discharge nozzle 99b.

  In the present embodiment, when two types of liquids are to be ejected in the same amount, or when it is desired to eject at a predetermined ratio, when the amount of one of the liquids is small, the liquid storage chambers 92a, When one end side of the operating arm 97 on the drive heads 95a, 95b side corresponding to 92b is pushed down, only the desired liquid is ejected, so that the liquid amount can be easily adjusted. Further, the one end of the operating arm 97 can be pushed down by using the finger of the hand holding the liquid discharge container 3, so that even if the hand cannot be used by discharging the liquid to the palm of the other hand. And the liquid can be discharged again.

Then, the 4th reference example of this invention is demonstrated based on FIG.12 and FIG.13. This reference example is different from the above-described embodiment of the present invention in that the operating arm is provided so as to engage with the opposing edges of both driving heads, and the driving head can be pushed down independently of the operating arms. It is in. Other configurations and operations are similar to those of the implementation described above, the description other than the operating arm and the drive head will be omitted.

  The drive heads 105a and 105b are provided for each pump (not shown) attached and fixed to each of the mounting cylinders 103a and 103b of the pump mounting body 103, respectively. Flat rectangular recess steps 106a and 106b are formed on the upper surfaces of the opposing edges of the drive heads 105a and 105b, and the operating arm 107 is engaged and placed on these recess steps 106a and 106b. Yes. The support arm 108 of the operating arm 107 has a round bar shape and is supported by the support cylinder 104 so as to be movable up and down. Each of the drive heads 105a and 105b is integrally provided with a discharge nozzle (not shown) and extends in the approaching direction.

In this reference example , when the operating arm 107 is pushed down, the two drive heads 105a and 105b are simultaneously lowered to operate each pump (not shown), and the liquid in each liquid storage chamber (not shown) is also illustrated. Discharge in a direction approaching each other from the discharge nozzles that are not. Therefore, two kinds of liquid can be reliably received even in a narrow part such as a palm. On the other hand, when the driving head, for example, the driving head 105b is pushed down without touching the operating arm 107, only the driving head 105b is lowered. Then, only the liquid in the corresponding liquid storage chamber (not shown) is discharged from the discharge nozzle (not shown) provided in the drive head 105b.

In the present embodiment, as in the implementation of the invention described above, and if you want to same amount discharging two kinds of liquids, when it is desired to discharge at a predetermined ratio, the amount of one liquid When the amount is small, when only the drive heads 105a and 105b corresponding to the liquid storage chamber of the small amount of liquid are pushed down, only the desired liquid is ejected, so that the liquid amount can be easily adjusted. In addition, since the drive heads 105a and 105b can be pushed down using the fingers of the hand holding the liquid discharge container, there is no problem even when the liquid is discharged to the palm of the other hand and the hand cannot be used. The liquid can be discharged again.

The present invention is not limited to the implementation described above, for example, it can be detachably mounted in the discharge Nozzle 9 9a, against the 99b to the drive heads 9 5a, 95 b . Furthermore, construction of the pump 9 6a, 96 b is not limited to those described above.

Furthermore, by rotatably supporting the supporting lifting shaft 98, and rotatable actuation arm 97, which by rotating 90 degrees, the drive head 95a of the operating arm 97, a passing engagement over to 95b configured to release, in the released state, the drive head 95a, Ru can also be configured to push down directly 95b to each other.
