The present invention will be specifically described with the following embodiments as examples, but the present invention is not limited by these. Therefore, each configuration described in detail for the embodiment of each drawing is one embodiment of the present invention, and various configurations can be made within the scope of the claims. Each embodiment can be combined based on ordinary knowledge by those skilled in the art, and configurations not specifically described for each embodiment have the same configuration as other embodiments or a configuration suitable for that embodiment be able to.

In this specification, the upward direction refers to the direction on which the refill container exists when the refill container is used in a suspended state, and the downward direction refers to the direction on which the contents take-out device exists. .

FIG. 1 shows one embodiment of a refill container 20 with an attached emptying device 10 in use hanging upside down. The refillable container 20 shown in FIG. 1 is a pouch-like container, and such a container has a gusset 22 formed at the bottom so that it can stand on its own and be sold at a store. The bottom gusset portion 22 has an unsealed portion on the side, and a hanging hook 30 such as an S-shaped hook can be attached through the unsealed portion. By attaching the hanging hook 30 to the attachment position 40 of a towel rack or the like in the bathroom, the refill container 20 to which the content take-out device 10 is attached can be used in a hanging manner.

FIG. 2 is a schematic diagram showing a state in which the contents take-out device 10 is about to be attached to the opening 21 of the refill container 20. As shown in FIG. 3A and 3B are schematic diagrams showing one embodiment of the mounting portion 11 for mounting the contents removing device 10 to the opening 21 of the refill container 20. FIG. 3(b) shows a state in which the content take-out device 10 can be attached to the opening 21 of the refill container 20, and FIG. 10 is shown.

The content take-out part 12 can be attached to the opening 21 of the refill container 20 using the attachment part 11 of the content take-out device 10 . The pouch-shaped refill container 20 is usually sold in stores with the opening 21 sealed by a tear-off seal. can be equipped with the contents take-out device 10.

Here, as shown in FIGS. 2 and 3(a), when the handle portion 11a of the attachment portion 11 is opened, a gap is formed between the attachment portion 11 and the content extraction portion 12. FIG. The opening 21 exposed by cutting the cut-off seal portion is formed of two sheets of film. By closing the handle portion 11a, one sheet of film is sandwiched between one attachment portion 11 and the content ejection portion 12, and another sheet is sandwiched between the other attachment portion 11 and the content ejection portion 12. of film can be sandwiched. As a result, the contents take-out device 10 can be attached to the opening 21 of the refill container 20 while preventing the contents from leaking out.

Content removal portion 12 is here in the form of a tube that can be inserted into opening 21 . When the piston portion 14 of the content take-out device 10 returns to the initial position from the pushed state, the inside of the syringe portion 13 of the content take-out device 10 is decompressed, and the content is taken out into the syringe portion 13 through the opening 21. Contents can flow through the portion 12 . Here, the length of the tube to be inserted into the opening 21 of the content removing section 12 can be 3.0 cm or less, 2.0 cm or less, or 1.0 cm or less. The short length of the tube inserted into the opening 21 makes it possible to use up the contents when the refill container 20 is used continuously in a hanging state.

The content dispenser 10 can have a flange 17 as shown in FIG. 3(a). The presence of such a flange 17 allows one-handed operation of the piston portion 14, as shown in FIG. Therefore, for example, the flange 17 is preferably positioned so that the thumb can press the piston portion of the content dispenser 10 while supporting the flange 17 with the index and middle fingers. The flange 17 is a portion separate from the attachment portion 11 for the container, and is a portion configured to enable one-handed operation. However, the position and shape of the flange 17 are not particularly limited as long as it is configured so that it can be operated with one hand.

4A and 4B are schematic diagrams showing one embodiment of the internal structure of the content take-out device 10, and FIG. It shows a state in which the content ejection portion B including the syringe portion 13, the piston portion 14, the nozzle 16, etc. is separated. FIG. 4(c) shows a state in which the piston part 14 is pushed in the contents discharge portion B. FIG.

In this embodiment, the content take-out device 10 may be separable into a content take-out portion A and a content discharge portion B. FIG.

The inventors of the present invention have found that a commercially available pump for shampoo or the like can be used without problems even if it is used in an upside-down state without causing liquid leakage or the like. , completed the content take-out device 10 of the present invention using a portion of the structure of a commercially available pump for shampoo, etc., as it is. Since such pumps are mass-produced, it has become possible to manufacture the content delivery portion B at very low cost. In the prior art content take-out device, the shape of the portion for discharging the content is very complicated in order to enable the content to be discharged without causing the content to leak when used in a suspended state. However, in the content take-out device 10 of the present invention, the cost of the content discharge portion B can be made very low, which is advantageous. However, if such an advantageous effect can be obtained, the content extraction portion A and the content discharge portion B may not be separable.

In the embodiment as shown in FIG. 4, the content extraction portion A and the content discharge portion B are configured so that the content extracted from the content removal portion A can flow to the content discharge portion B without leaking out on the way. It has become.

As shown in FIG. 4B, the content discharge portion B can have a content distribution portion 12a in communication with the content removal portion 12 of the content removal portion A, and the content distribution portion 12a is , the contents can be circulated inside the syringe part 13 .

In the syringe portion 13, the content that has flown through the content flow portion 12a can be stored. It is preferably discharged from nozzle 16 through one valve 15 . Therefore, the volume inside the syringe portion 13 can be made the same as the volume of the contents to be discharged by one reciprocating motion of the piston portion 14 .

As shown in FIG. 4(b), the piston portion 14 of the content take-out device 10 has a gasket 14a. When the piston portion 14 is pushed in, the piston portion 14 is stored in the syringe portion 13 by the gasket 14a. The contents can be pushed upward without leaking to the lower side of the syringe part 13 . That is, the gasket 14a can push out upward the contents other than the contents that pass through the first valve 15 and flow downward.

Further, as shown in FIG. 4B, the piston portion 14 of the contents take-out device 10 has a plunger 14b, and the entirety of the piston portion 14 moves into the syringe portion 13 by vertically moving the plunger 14b. It is possible to reciprocate inside. The plunger 14b can be moved upward by pressing the lowermost flat surface 14c of the container dispenser 10, which can be pressed with the thumb.

The piston part 14 is at the lowest position in the initial position shown in FIG. 4(b), and moves upward in the pushed state shown in FIG. 4(c). can quickly return to the initial position. Such a spring has a configuration commonly used in pumps for commercially available shampoos and the like, and can be used as it is in the contents take-out device 10 of the present invention.

The content flow portion 12a of the content discharge portion B may have a second valve 18, whereby the content pushed out of the syringe portion 13 by the piston portion 14 is directed to the content ejection portion A. backflow can be prevented. However, since most of the contents in the syringe part 13 flow from the first valve 15 to the nozzle 16, even if the second valve 18 is not provided, the amount of contents flowing back to the contents extraction part A is so large. Since there is no second valve 18, the second valve 18 may not be present.

The second valve 18 can be a ball-shaped valve body and a valve seat therefor, as shown in FIG. 4(c). Such a ball-shaped valve body and valve seat therefor may be used in commercially available pumps for shampoos, etc., and can be used as they are in the contents take-out device 10 of the present invention.

FIG. 5 is a schematic diagram showing one embodiment of the piston part 14 and the first valve 15 of the emptying device, FIG. 5(a) showing the state of the initial position of the piston part 14, The first valve 15 shows a closed state, and FIG. 5(b) shows a state where the piston portion 14 is pushed in, showing a state where the first valve 15 is open. there is

In this embodiment, there is an internal channel 19 in the piston portion 14 through which the contents flow to the nozzle 16 . The internal flow path 19 communicates with the upper portion of the gasket 14a and is closed by the first valve 15 when the piston portion 14 is in the initial position. When the piston portion 14 is pushed in, the gasket 14a moves upward, but the first valve 15 is configured to move upward by a larger amount of movement than the upward movement amount of the gasket 14a. , thereby creating a gap between the upper portion of the gasket 14 a and the first valve 15 , allowing the contents in the syringe to flow into the internal flow path 19 . Therefore, in this case, more precisely, the upper portion of the gasket 14a constitutes the valve seat, and the first valve 15 constitutes the valve body. Such a valve body and valve seat may be used in commercially available pumps for shampoos, etc., and can be used as they are in the contents take-out device 10 of the present invention.

The internal flow path 19 may be configured so that the content can be discharged in the form of foam or mist when discharged from the nozzle. For example, the internal flow path 19 may have a mesh that allows the contents to be discharged in the form of bubbles, or has a known structure that takes in air so that the contents can be discharged in the form of a mist. may

FIG. 6 shows the emptying device 10 attached to a refill container 20 of another embodiment. The refill container 20 of this embodiment has an opening 21 at the center in the width direction. However, since the contents are concentrated in the opening 21, the contents can be used up to the end, which is preferable.

Such a refill container 20 is usually sold at stores with a cap attached to the opening 21 . When the content take-out device 10 is attached to the opening 21 of the refill container 20, the attachment portion 11 of the content take-out device 10 may be attached instead of the cap. and is preferred due to the significant simplification compared to the embodiment as shown in FIG.
