Description

Fluid discharge container

Technical Field

The present invention relates to a fluid discharge container for storing a fluid-containing bag and discharging the fluid contained in the fluid-containing bag to the outside.

Background

Conventionally, a fluid discharge container has been widely used, which contains various fluids such as a permanent wave, a shampoo, a rinse, a shower gel, a disinfectant fluid, and a seasoning in the container and discharges the fluids to the outside of the container. In general, in the fluid discharge container, a fluid is directly contained in the container, and the fluid in the container is sucked by a discharge mechanism such as a hand pump or a trigger pump provided in an upper portion of the container to be discharged to the outside of the container.

Such a fluid dispensing container is discarded together with the container when the fluid in the container is used up, but from the viewpoint of ecology (natural environmental protection), when the fluid in the container is used up, the same fluid contained in the refill bag can be replaced into the fluid dispensing container. However, such replacement of fluid from the bag to the container is problematic in that the fluid may contact the air outside the bag or container, thereby deteriorating the quality of the fluid.

Therefore, recently, attention is paid to a fluid discharge container which stores a fluid-containing bag in the container and discharges the fluid in the bag to the outside, without directly containing the fluid in the container. More specifically, the fluid discharge container includes: a receiving bag having a connecting member at an upper portion; a lower container storing the receiving bag; an upper container having a locking member for locking a connector of the storage bag; and a discharge mechanism provided in the upper container; after the connector of the storage bag containing the fluid is locked to the locking member of the upper container, the upper container is mounted to the lower container while the storage bag is contained in the lower container (see patent document 1).

SUMMERY OF THE UTILITY MODEL

Problems to be solved by the utility model

However, in such a fluid discharge container, when the storage bag is stored in the container, it is necessary to specially clamp the connector of the storage bag to the locking capsule of the upper container, and when the storage bag is taken out from the container, it is necessary to specially take out the connector of the storage bag from the locking capsule of the upper container. Therefore, there is a problem that the method of replacing the storage bag is confusing for general consumers and the replacement work is troublesome. Further, since the locking capsule is provided in the upper container, there is a problem that the manufacturing cost is structurally increased.

In view of the above-described problems, an object of the present invention is to provide a fluid dispensing container in which a storage bag can be easily and reliably replaced by a general consumer.

Means for solving the problems

To achieve the above object, the present invention provides a fluid discharge container for storing a fluid-containing bag and discharging the fluid contained in the fluid-containing bag to the outside; the fluid discharge container is characterized by comprising: a receiving bag having a connector provided with a through hole at an upper portion thereof; a lower container having an opening portion through which the storage bag is stored; an upper container detachably provided in the lower container; and a discharge mechanism provided in the upper container and having a male member inserted into the through hole of the connector of the storage bag; the maximum outer diameter of the connector is formed to be larger than the inner diameter of the opening of the lower container and smaller than the inner diameter of the upper container, and is engaged with the lower container in the opening of the lower container.

Accordingly, when the storage bag of the fluid discharge container is replaced, the upper container is taken out from the lower container, and the used storage bag is taken out from the upper container or the lower container.

Furthermore, the connecting member may be fixed in a manner of being sandwiched by the upper container and the lower container. Accordingly, the receiving bag can be stably stored in the lower container.

Furthermore, the connecting member may be held between the upper container and the lower container by abutting against a section provided on the inner side of the upper container. Accordingly, the connecting member for accommodating the bag can be reliably fixed between the upper container and the lower container. In addition, even if the overall size of the upper container is not changed, the height of the segment can be designed in various ways, so that the clamping degree of the connecting piece of the containing bag can be changed easily. In the case where the shape of the step portion is reflected on the outer side of the upper container, an overcap member for covering the discharge mechanism may be fitted on the outer portion of the step portion of the upper container.

The connecting piece can also be provided with an upper connecting piece plate arranged on the upper side of the axis direction and a lower connecting piece plate arranged on the lower side of the axis direction; a maximum outer diameter of the upper connector plate is formed to be smaller than an inner diameter of the opening portion of the lower container, and a maximum outer diameter of the lower connector plate is formed to be larger than an inner diameter of the opening portion of the lower container; the upper surface of the peripheral edge portion of the lower connector plate abuts against the segment portion of the upper container, and the lower surface of the peripheral edge portion of the lower connector plate abuts against the peripheral wall portion of the lower container, whereby the connector is fixed in a state of being sandwiched between the upper container and the lower container. Accordingly, by locking the other locking member between the upper gusset plate and the lower gusset plate at the time of manufacture, the fluid can be stably filled in the storage bag, and the gusset of the storage bag can be reliably fixed to the opening portion of the lower container at the time of use.

In the above-described connector, a locking member may be provided on a lower surface of a peripheral portion of the lower connector plate, the locking member being located inside a peripheral wall portion of the lower container. Accordingly, the movement of the coupling member in the radial direction is restricted, and the coupling member can be more reliably fixed to the opening of the lower container.

Furthermore, the connecting member may include an upper connecting member plate provided on an upper side in the axial direction and a lower connecting member plate provided on a lower side in the axial direction; a maximum outer diameter of the upper connector plate is formed to be larger than an inner diameter of the opening portion of the lower container, and a maximum outer diameter of the lower connector plate is formed to be smaller than the inner diameter of the opening portion of the lower container; the upper surface of the peripheral edge portion of the upper connector plate abuts against the segment portion of the upper container, and the lower surface of the peripheral edge portion of the upper connector plate abuts against the peripheral wall portion of the lower container, whereby the connector is fixed in a state of being sandwiched by the upper container and the lower container. Accordingly, the connecting member of the storage bag can be reliably fixed to the opening of the lower container in use.

In the connector, a peripheral edge portion of the lower connector plate may abut against an inner surface of a peripheral wall portion of the lower container. Accordingly, the movement of the coupling member in the radial direction is restricted, and the coupling member can be more reliably fixed to the opening of the lower container.

Further, a depressed recess may be formed radially inward. Accordingly, it is generally required that the user can easily replace the receiving bag by simply picking up the coupling member by attaching fingers (e.g., index finger and thumb) to the concave portion of the coupling member of the receiving bag.

Further, the connecting member may be formed with at least 2 recesses, each recess being formed in a manner to face each other in the radial direction. Accordingly, it is generally required that the user can more easily pick up the coupling member and more easily replace the receiving bag by attaching a plurality of fingers (e.g., index finger and thumb) to the 2 recesses of the coupling member of the receiving bag.

Further, the connector may be such that the male member of the discharge mechanism is inserted into the through hole in a close contact state. Accordingly, the fluid contained in the containing bag can be surely prevented from contacting the outside air in use.

Effect of the utility model

According to the present invention, when the storage bag of the fluid discharge container is replaced, the upper side container is taken out from the lower side container, and the used storage bag is taken out from the upper side container or the lower side container. In addition, since the structure is simple in which the coupling member of the storage bag is directly engaged with the lower container, the manufacturing cost can be suppressed.

Detailed Description

Next, an embodiment of a fluid dispensing container according to the present invention (hereinafter referred to as a main container) will be described with reference to fig. 1 to 9.

As shown in fig. 1 and 2, the container includes: a receiving bag 1 for receiving a fluid such as shampoo or rinse, lotion, etc.; a lower container 2 storing the receiving bag 1; an upper container 3 detachably provided in the opening 23 of the lower container 2; and a discharge mechanism 4 provided in the upper container 3.

As shown in fig. 4, the storage bag 1 is composed of a flexible bag body 11 made of a synthetic resin material, which is generally called a self-standing bag, and a rigid connecting member 12 made of a synthetic resin material.

The bag body 11 includes: a 1 st sheet 111 disposed on one side thereof and having a rectangular front view; a 2 nd sheet 112 disposed on the other side and having the same size and shape as the 1 st sheet 111; and a 3 rd sheet 113 disposed on the lower side; the upper ends (except for the portion where the connector 12 is disposed) and the side ends of the 1 st sheet 111 and the 2 nd sheet 112 are heat-sealed and welded to each other, and the lower ends of the 1 st sheet 111 and the 2 nd sheet 112 and the peripheral edge of the 3 rd sheet portion 113 are heat-sealed and welded to each other, thereby forming a space capable of containing fluid inside as a whole. The bag body 11 is not limited to the self-supporting bag, and may be a flat bag composed of 2 sheets, an accordion bag composed of 4 sheets, or other bag bodies.

Further, height H1 of bag body 11 is formed to be equal to or smaller than depth H2 inside lower container 2. The width of bag 11 is set to a size that bag 11 can be stored in lower container 2 when bag 11 stores fluid.

The connector 12 includes: a body portion 121; an upper connector plate 122 provided on the upper side of the body 121 in the axial direction; a lower connector plate 123 provided on the lower side of the body 121 in the axial direction; a through hole 124 provided to pass the main body 121 in the axial direction; and a cover member 125 provided at a lower end portion of the through hole 124; the lower side surface of the main body 121 is sandwiched between the 1 st sheet 111 and the 2 nd sheet 112 by heat sealing, and the connecting member 12 is provided at the center of the upper end of the bag 11 in such a manner that the through hole 124 and the axial direction of the bag 11 are aligned.

As shown in fig. 7 (a), the upper link plate 122 is formed in a flat plate shape extending in the planar direction, and 2 recessed portions 122b recessed inward in the radial direction are formed so as to face each other. On the other hand, the lower link plate 123 of the link 12 is also formed in a flat plate shape extending in the planar direction, similarly to the upper link plate 122 of the

link

12, and 2 recesses 123b depressed inward in the radial direction are formed in a manner facing each other. The concave portion 122b of the upper connector plate 122 and the concave portion 123b of the lower connector plate 123 are formed to be flush with each other along the axial direction, and the connector 12 can be easily removed by moving the fingers (for example, the index finger and the thumb) of the operator along the

concave portions

122b and 123 b.

The maximum outer diameter R1 of the lower link plate 123 is formed larger than the inner diameter R3 of the opening 23 of the lower container 2. Accordingly, as shown in fig. 3, when the storage bag 1 is stored in the lower container 2, the lower surface of the peripheral edge portion 123a of the lower connector plate 123 abuts against the end surface of the upper end portion 22a of the lower container 2, and the connector 12 of the storage bag 1 is locked to the opening 23 of the lower container 2, and the bag body 11 of the storage bag 1 is suspended in the lower container 2.

Further, the maximum outer diameter R1 of the lower link plate 123 is formed smaller than the inner diameter R4 of the upper container 3. The maximum outer diameter R2 of the upper link plate 122 is also formed smaller than the inner diameter R3 of the opening 23 of the lower container 2. As a result, as shown in fig. 3, when the upper container 3 is completely mounted on the lower container 2 in a state where the storage bag 1 is stored in the lower container 2, the entire connector 12 is stored in the internal space 33 of the upper container 3.

The upper link plate 122 and the lower link plate 123 are provided so as to face each other with a predetermined distance in the axial direction of the link 12. Accordingly, when the storage bag 1 is filled with a fluid during manufacturing, the fluid can be stably filled by locking the locking member provided separately between the upper and

lower gusset plates

122 and 123 of the gusset 12 of the storage bag 1.

As shown in fig. 5, the lower container 2 is a rigid container made of synthetic resin and composed of a circular bottom wall 21 and a cylindrical peripheral wall 22 standing from the periphery of the bottom wall 21, and has an opening 23 formed in the upper part of the peripheral wall 22 and a male screw 24 formed on the outer peripheral surface of the upper part of the peripheral wall 22. The screw portion 24 is screwed into an internal thread portion 34 of the upper container 3 as described later.

As shown in fig. 6, the upper container 3 is a rigid container made of synthetic resin and composed of a circular top wall portion 31 and a cylindrical peripheral wall portion 32 hanging from the periphery of the top wall portion 31, and forms an internal space 33 covering the connector 12 of the storage bag 1.

The upper container 3 has a female screw portion 34 formed on the inner peripheral surface of the lower portion of the peripheral wall portion 32, and is mounted on the lower container 2 by being screwed to the male screw portion 24 formed on the lower container 2.

The upper container 3 has a through hole 35 formed in the center of the top wall 31, and the male member 41 of the discharge mechanism 4 passes through the through hole 35 when the discharge mechanism 4 is attached to the upper container 3.

The upper container 3 has a step 36 formed in an upper portion of the peripheral wall 32 along a circumferential direction and having an L-shaped cross section in an axial direction. This step 36 is formed with the following width: when the upper container 3 is completely mounted on the lower container 2, it is positioned radially inward of the lower gusset plate 123 of the gusset 12 of the storage bag 1 and radially outward of the upper gusset plate 122.

Therefore, as shown in fig. 3, when the upper container 3 is completely mounted on the lower container 2 in a state where the storage bag 1 is stored in the lower container 2, the upper surface of the peripheral portion 123a of the lower connector plate 123 abuts against the lower surface of the step portion 36 of the upper container 3, and the lower surface of the peripheral portion 123a of the lower connector plate 123 abuts against the upper end portion 22a of the peripheral wall portion 22 of the lower container 2, so that the connector 12 can be fixed in a state of being sandwiched between the upper container 3 and the lower container 2. Further, even if the overall size of the upper container 3 is not changed, the height of the step portion 36 can be variously designed, so that the degree of sandwiching the connecting piece 12 of the storage bag 1 can be easily changed. Further, as in the present embodiment, when the outer side of the peripheral wall portion 32 of the upper container 3 is depressed by reflecting the shape of the step portion 36 on the outer side of the upper container 3, the top lid member 5 for covering the discharge mechanism 4 can be fitted to the outer portion of the step portion 36 of the upper container 3.

Further, the step portion 36 is formed with a height in the axial direction as follows: when the upper container 3 is completely mounted on the lower container 2, a slight gap is formed between the upper surface of the upper connector plate 12 and the lower surface of the top wall portion 31 of the upper container 3. With this, when the upper container 3 is mounted on the lower container 2, the female screw portion 34 of the upper container 3 and the male screw portion 24 of the lower container 2 can be securely screwed up to the extreme end.

Further, the step portion 36 is formed with the following axial width: when the upper container 3 is completely mounted on the lower container 2, a slight gap or slight contact is generated between the side surface of the upper connector plate 122 and the side surface of the step portion 36. With this, after the upper container 3 is taken out from the lower container 2, the storage bag 1 can be easily taken out from the upper container 3 without rubbing the inner surface of the peripheral wall portion 32.

As shown in fig. 6, the discharge mechanism 4 is provided on the upper surface of the top wall portion 31 of the upper tank 3 by a so-called push pump. The discharge mechanism 4 includes: a tubular male member 41 having a suction port 44 for sucking fluid to a lower end portion; a pump section 42 having a discharge port 45 for discharging fluid to an upper end; and a fluid passage 43 communicating the suction port 44 and the discharge port 45 so as to penetrate the inside.

As shown in fig. 3, when the upper container 3 is mounted on the lower container 2, the discharge mechanism 4 is brought into a state facing the inside 1 of the storage bag by inserting the male member 41 into the through hole of the linker 12 of the storage bag 1 in a close contact state and pushing out the cap member 125 provided at the lower end portion of the through hole 124 of the linker 12 of the storage bag 1. With this, when the pump section 42 is depressed one or more times by the hand of the operator, the fluid contained in the storage bag 1 is sucked from the suction port 44 of the male member 41 by the suction action of the pump, and is discharged from the discharge port 45 to the outside of the container through the fluid passage 43.

Next, a method of replacing the storage bag 1 of the present container will be described.

First, a method of taking out the used storage bag 1 from the container will be described.

As shown in fig. 8 (a), when the upper container 3 is rotated counterclockwise with respect to the lower container 2, the female screw portion 34 of the upper container 3 and the male screw portion 24 of the lower container 2 are gradually unscrewed, and the upper container 3 is separated from the lower container 2.

As shown in fig. 8 (b), when the upper container 3 is taken up from the lower container 2 after the internal thread portion 34 of the upper container 3 and the external thread portion 24 of the lower container 2 are completely unscrewed, the used storage bag 1 is taken out from the lower container 2 in a state of being mounted on the upper container 3. The reason why the used storage bag 1 is mounted on the upper container 3 is that the male member 41 provided in the discharge mechanism 4 of the upper container 3 is inserted in close contact with the through hole of the mounting piece 12 of the storage bag 1.

Then, as shown in fig. 8 (c), when the used storage bag 1 is pulled down with respect to the upper receptacle 3, the male member 41 of the discharge mechanism 4 is pulled out from the through hole 124 of the connector 12 of the storage bag 1, and the storage bag 1 is taken out from the upper receptacle 3.

After that, the used storage bag 1 taken out of the container may be discarded.

Next, a method of storing a new storage bag 1 in the present container will be described.

When a new storage bag 1 is inserted from the opening 23 of the lower container 2 as shown in fig. 9 (a), the storage bag 1 is stored in the lower container 2 as shown in fig. 9 (b). At this time, since the maximum outer diameter R1 of the lower connector plate 123 of the connector 12 of the storage bag 1 is formed larger than the inner diameter R3 of the opening 23 of the lower container 2, as shown in fig. 7, the lower surface of the peripheral edge portion 123a of the lower connector plate 123 of the connector 12 abuts against the end surface of the upper end portion 22a of the peripheral wall portion 22 of the lower container 2. Therefore, the connector 12 of the storage bag 1 is engaged with the opening 23 of the lower container 2, and the bag body 11 of the storage bag 1 is suspended in the lower container 2.

Then, as shown in fig. 9 (c), when the internal thread portion 34 of the peripheral wall portion 32 of the upper container 3 and the external thread portion 24 of the peripheral wall portion 22 of the lower container 2 are combined and the upper container 3 is rotated clockwise with respect to the lower container 2, the internal thread portion 34 of the upper container 3 and the external thread portion 24 of the lower container 2 are gradually screwed together, and the upper container 3 is mounted on the lower container 2. At this time, as shown in fig. 3, the upper surface of the peripheral edge portion 123a of the lower connector plate 123 of the storage bag 1 abuts against the lower surface of the step portion 36 of the upper container 3. Therefore, the upper surface of the peripheral edge portion 123a of the lower connector plate 123 abuts against the lower surface of the step portion 36 of the upper container 3, and the lower surface of the peripheral edge portion 123a of the lower connector plate 123 abuts against the end surface of the upper end portion 22a of the peripheral wall portion 22 of the lower container 2, so that the connector 12 can be fixed in a state of being sandwiched between the upper container 3 and the lower container 2.

When the storage bag 1 is replaced with the present container as described above, it is convenient for the general consumer to simply and surely replace the storage bag 1 by taking out the upper container 3 from the lower container 2 and then taking out the used storage bag 1 from the upper container 3, because it is only necessary to store a new storage bag 1 in the lower container 2 and then mount the upper container 3 on the lower container 2. Further, since the coupling member 12 of the storage bag 1 is directly locked to the lower container 2, the manufacturing cost can be suppressed.

In the present embodiment, the coupling member 12 is fixed in a state of being sandwiched between the step portion 36 of the upper container 3 and the upper end portion 22a of the lower container 2, but may be fixed in a state of being sandwiched between the upper container 3 and the lower container 2 by another structure.

As shown in fig. 10, the coupling 12 may be configured such that the opening 23 of the lower container 2 is locked to the lower container 2 (the upper end 22a) without providing the step 36 on the upper container 3.

The maximum outer diameter R1 of the lower link plate 123 is formed larger than the maximum outer diameter R2 of the upper link plate 122 in the above-described link 12, but all of them may be formed to have the same maximum outer diameter as shown in fig. 10.

As shown in fig. 11, the connector plate 12 may be provided with a locking capsule 123c on the lower surface of the peripheral edge portion 123a of the lower connector plate 123 for controlling the radial movement, and the locking capsule 123c may be positioned inside the peripheral wall portion 22 of the lower container 2.

As shown in fig. 12, the connector 12 may be fixed in a state in which the maximum outer diameter of the upper connector plate 122 is formed larger than the inner diameter of the opening 23 of the lower container 2, the maximum outer diameter of the lower connector plate 123 is formed smaller than the inner diameter of the opening 23 of the lower container 2, the upper surface of the peripheral edge portion 122a of the upper connector plate 122 abuts against the lower surface of the step portion 36 of the upper container 3, the lower surface of the peripheral edge portion 122a of the upper connector plate 122 abuts against the end surface of the upper end portion 22a of the peripheral wall portion 22 of the lower container 2, and the connector 12 is sandwiched between the upper container 3 and the lower container 2. At this time, the outer peripheral surface of the peripheral edge portion 123a of the lower connector plate 123 abuts against the inner surface of the peripheral wall portion 22 of the lower container 2, thereby restricting the radial movement of the connector 12.

In the

connector

12, 2

recesses

122b and 123b are provided in both the upper connector plate 122 and the lower connector plate 123, but 1 or 3 or more recesses may be provided or no recesses may be provided.

The connector 12 (the upper connector plate 122 and the lower connector plate 123), the lower container 2, or the upper container 3 is not limited to the above shape, and may have a shape other than a circular shape. In this case, the maximum outer diameter or inner diameter described above corresponds to the maximum outer dimension or inner dimension of each member in the planar direction.

The male member 41 of the discharge mechanism 4 is fixed in a close contact state to the through hole 124 of the connector 12 of the storage bag 1, but may be fixed in a non-close contact state. In this case, when the used storage bag 1 is replaced with a new storage bag 1, and the upper receptacle 3 is taken out from the lower receptacle 2, the used storage bag 1 remains stored in the lower receptacle 2 as shown in fig. 8 (b), and therefore, the used storage bag 1 can be easily taken out from the present receptacle by removing the coupling member 12 of the used storage bag 1 and pulling out the used storage bag from the lower receptacle 2.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be added to the illustrated embodiments within the same scope or equivalent scope as the present invention.
