JP, 2012-232228, A

However, in the above-described conventional ejector, since the contents are ejected when the pressing head is depressed, for example, when ejecting the contents on the palm, one hand (the hand opposite to the one holding down the pressing head) It was difficult to receive the contents with both hands.
In addition, if one hand is blocked for some reason (such as holding a child), it is difficult to receive the discharged contents with the other hand, even if the pressing head can be depressed with the other hand. .

  The present invention has been made in view of such circumstances, and an object thereof is to be able to receive a discharged content with both hands, to perform a discharge operation of the content, and to receive the discharged content. An object of the present invention is to provide a dispenser which can be performed with only one hand.

In order to solve the above problems, the present invention proposes the following means.
The dispenser according to the present invention includes a stem arranged to be movable downward in an upwardly biased state at a mouth portion of a container body in which contents are stored, and a stem which is movable up and down and which is provided in the stem. A storage cylinder that communicates with the storage cylinder and stores the content from the stem as the stem moves downward; a nozzle cylinder that communicates with the storage cylinder and that has a discharge hole that discharges the content; And a vertical movement of the discharge piston, which is vertically slidable in the storage cylinder, a pressing head which moves up and down in cooperation with the stem, and holds the pressing head at the lowest position . comprising a holding portion, wherein the pressing head has a linkage tubular portion disposed above the reservoir cylinder upper portion while being inserted into said reservoir cylinder and said stem, said said linking tube portions scan Between the beam, is formed an annular flow passage, when the stem is moved downward, is supplied to the reservoir cylinder side contents is through the flow passage, the holder has an operating portion, The holding of the pressing head is released when the operation unit is operated.

According to the present invention, by pushing down the pushing head and moving the stem downward with respect to the storage cylinder, the discharge piston can be moved downward within the storage cylinder, and at the same time, the content from the stem is moved into the storage cylinder. Can be stored once. Further, when the push head is lowered to the lowest position, the holding unit can hold the push head at the lowest position.
Thereafter, when the operating portion is operated to release the holding of the pressing head by the holding portion, the stem is restored and moved upward by the upward biasing force. Therefore, the discharge piston moves upward in the storage cylinder with the restoration movement of the stem, and supplies the content stored in the storage cylinder into the nozzle cylinder so as to push it out from the storage cylinder. Thereby, the content can be discharged to the outside through the discharge hole.

In this way, since the contents can be temporarily stored in the storage cylinder, it is possible to prevent the contents from being discharged when the stem is moved downward by a pushing operation or the like, and then the stem is restored and moved upward. Sometimes the contents can be ejected.
Therefore, the discharged contents can be received not only by one hand but also by both hands. Furthermore, even if one hand is blocked for some reason (for example, holding a child or carrying a luggage), the other one hand alone can be used to discharge the contents and The discharged contents can be received. Therefore, it is very easy to use and convenience can be improved.
Moreover, when the contents are once stored in the storage cylinder and the push head is lowered to the lowest position, the holding portion can hold the push head at the lowest position. Therefore, when the pressing head is released and the hand is released from the pressing head, it is possible to prevent the pressing head and the stem from rising and discharging the contents. Therefore, it is possible to eject the contents by operating the operation unit after bringing the hand separated from the pressing head close to the nozzle cylinder and raising the pressing head and the stem. Further, for example, after the ejection is completed, the pressing head is lowered for the next ejection, and the pressing head is held at the most lowered position by the holding portion, so that the next ejection can be smoothly performed. Therefore, the convenience can be further improved.

  The holding portion includes an upper locking portion that is linked to the vertical movement of the pressing head, and a lower locking portion that is disposed below the upper locking portion, and the pressing head is directed to the lowest position. When lowering, the upper locking portion and the lower locking portion are in sliding contact with each other, and at least one of the upper locking portion and the lower locking portion is displaced to cause the upper locking portion to move. The holding portion may restrict the upward movement of the pressing head by locking the lower portion and the lower locking portion with each other.

  In this case, at the time when the push-down head descends toward the lowest position, at least one of the upper-side engaging portion and the lower-side engaging portion is in sliding contact with the upper-side engaging portion and the lower-side engaging portion. Is displaced, and the upper locking portion and the lower locking portion are locked to each other, so that the holding portion regulates the upward movement of the pressing head. Therefore, by performing the work of lowering the pressing head toward the lowest position, the holding unit can hold the pressing head at the lowest position. Thereby, convenience can be further improved.

  A restricting portion that restricts relative movement of the upper engaging portion and the lower engaging portion in a circumferential direction around the axis of the stem may be further provided.

  In this case, the restricting portion restricts the relative movement of the upper locking portion and the lower locking portion in the circumferential direction. Therefore, when the push-down head descends toward the lowest position, the upper locking portion and the lower locking portion can be positioned relative to each other in the circumferential direction and can be reliably locked.

  The nozzle cylinder may extend forward from the storage cylinder side, and the operation portion may be disposed in front of the storage cylinder.

  In this case, the nozzle cylinder extends forward from the storage cylinder side, and the operating portion is arranged in front of the storage cylinder. Therefore, immediately after the operating portion is manually operated to release the holding of the pressing head by the holding portion, the hand can be brought close to the nozzle cylinder. Thereby, convenience can be further improved.

  The operation unit may be disposed below the ejection hole when the push-down head is located at the lowest position.

  In this case, the operating portion is arranged below the ejection hole when the pressing head is located at the lowest position. Therefore, immediately after the operating portion is manually operated to release the holding of the pressing head by the holding portion, the hand can be positioned below the ejection hole. Thereby, convenience can be further improved.

A liquid cylinder whose inside communicates with the said stem, while vertical movement in cooperation with the stem, is vertically slidably disposed in said fluid for the cylinder for the liquid with the downward movement of the stem And a liquid piston for supplying the contents in the cylinder into the stem.

  In this case, when the stem is moved downward with respect to the storage cylinder, the liquid piston moves downward in the liquid cylinder in cooperation with the stem. Thereby, the contents in the liquid cylinder can be supplied into the storage cylinder through the stem. Therefore, the discharge amount of the content discharged by one discharge operation can be easily defined by the inner volume of the liquid cylinder, and for example, a fixed amount of the content can be discharged.

  Of the internal volume of the storage cylinder, the increased volume that increases with the downward movement of the discharge piston is equal to or greater than the volume of the internal volume of the liquid cylinder that decreases with the downward movement of the liquid piston. It may have been done.

  In this case, when the stem is moved downward, it is possible to prevent an amount of content exceeding the internal volume of the storage cylinder from being supplied into the storage cylinder. Therefore, when the stem moves downward, the contents can be reliably stored in the storage cylinder, and it is difficult for the contents to flow from the storage cylinder into the nozzle cylinder. Therefore, it is easy to effectively prevent the contents from leaking from the discharge hole when the stem moves downward.

  According to the dispenser of the present invention, the discharged contents can be received with both hands, and the discharging operation of the contents and the reception of the discharged contents can be performed with only one hand.

And a liquid piston 15 that is vertically slidable.

The storage cylinder 10 is formed in a tubular shape that is arranged coaxially with the axis O, and is formed integrally with the mounting cap 2.
The storage cylinder 10 extends upward from the inner peripheral edge of the top wall of the mounting cap 2, and is arranged above the storage cylinder 20 and has a smaller diameter than the storage cylinder 20. The guide tubular portion 21, an annular top wall portion 22 that connects the upper end portion of the storage tubular portion 20 and the lower end portion of the guide tubular portion 21, and the guide tubular portion 21 that is erected on the top wall portion 22 in the radial direction. A surrounding cylinder portion 27 that surrounds from the outside.

  A first air hole 23 that communicates the inside and the outside of the storage tubular portion 20 is formed at the connection portion between the storage tubular portion 20 and the top wall portion of the mounting cap 2. The guide cylinder portion 21 is formed such that the inner diameter thereof is smaller than the inner diameter of the stem 3, and a linking cylinder portion 71 of the pressing head 5 described later is vertically movably inserted therein.

  An annular seal portion 24, which is slidably in contact with the outer peripheral surface of the linking tubular portion 71, is provided at a connecting portion between the guide tubular portion 21 and the top wall portion 22 so as to project downward. As a result, the space between the linking cylinder portion 71 and the seal portion 24 is tightly sealed.

The nozzle cylinder 12 extends forward from the storage cylinder 10 side. Hereinafter, in the radial direction, the direction in which the nozzle cylinder 12 extends from the storage cylinder 10 is the front, the opposite direction is the rear, and the direction orthogonal to the axis O direction and the front-back direction is the left-right direction.
The nozzle cylinder 12 is connected to a first nozzle cylinder 30 integrally formed with the guide cylinder portion 21 of the storage cylinder 10, a second nozzle cylinder 31 connected to the first nozzle cylinder 30, and a second nozzle cylinder 31. And a third nozzle cylinder 32, and is connected to the storage cylinder 10.

The first nozzle cylinder 30 is formed so as to extend radially outward from the outer peripheral surface of the guide cylinder portion 21 and penetrate the surrounding cylinder portion 27, and a part thereof is integrally formed with the top wall portion 22. . A through hole 25 that vertically penetrates the top wall portion 22 is formed in a portion of the top wall portion 22 that is integrally formed with the first nozzle cylinder 30. As a result, the inside of the storage cylinder portion 20 and the inside of the first nozzle cylinder 30 communicate with each other through the through hole 25.
The first nozzle cylinder 30 projects outward in the radial direction from the mounting cap 2, and the tip end side thereof is a small-diameter cylinder portion 30a having an outer diameter smaller than that of the other parts of the first nozzle cylinder 30.

  The second nozzle cylinder 31 is externally fitted to the small diameter cylinder portion 30a of the first nozzle cylinder 30, and the middle portion is bent downward at an angle of approximately 90 degrees. The tip end side of the second nozzle cylinder 31 is a small-diameter cylinder portion 31a having an outer diameter smaller than that of the other portion of the second nozzle cylinder 31.

The third nozzle cylinder 32 is fitted onto the small-diameter cylinder portion 31 a of the second nozzle cylinder 31, and the discharge hole 11 is formed at the tip thereof. In the illustrated example, the discharge hole 11 is formed in a taper shape in a vertical cross section and opens downward.
Inside the second nozzle cylinder 31 and the third nozzle cylinder 32, a cylindrical core body 33 extending in the direction of the axis O is arranged. The core body 33 is formed such that the outer diameter thereof is smaller than the inner diameters of the second nozzle cylinder 31 and the third nozzle cylinder 32, and is arranged with a slight gap between the core body 33 and the discharge hole 11. As a result, the contents flow between the outer peripheral surface of the core body 33 and the inner peripheral surfaces of the second nozzle cylinder 31 and the third nozzle cylinder 32, and are discharged from the discharge holes 11 to the outside.

  In the illustrated example, the nozzle cylinder 12 is formed in an L shape in side view, but the invention is not limited to this case, and is formed in, for example, a straight shape extending radially outward from the storage cylinder 10. It does not matter. Further, a topped cylindrical nozzle tip may be attached to the tip of the core body 33 to eject the contents in, for example, a mist state.

  The regulation plate 16 projects forward from the storage cylinder 10. The regulation plate 16 is formed in a rectangular shape that is long in the direction of the axis O. The upper end of the restriction plate 16 is connected to the nozzle cylinder 12 (first nozzle cylinder 30), and the lower end of the restriction plate 16 is connected to the mounting cap 2. A pair of regulation plates 16 are provided at intervals in the circumferential direction.

  The liquid cylinder 14 is formed in a tubular shape and is arranged inside the opening A1 of the container body A coaxially with the axis O. The liquid cylinder 14 includes an annular flange portion 41 arranged on the upper open end of the mouth portion A1 of the container body A via a packing 40, and a straight cylindrical portion extending downward from an inner peripheral edge portion of the flange portion 41. 42, and a suction cylinder portion 43 extending further downward from the lower end portion of the straight cylinder portion 42.

A second air hole 44 that radially penetrates the straight tube portion 42 is formed in the straight tube portion 42 at a portion located below the flange portion 41. As a result, the inside of the container body A and the inside of the liquid cylinder 14 communicate with each other through the second air holes 44.
An annular lower valve seat portion 45 is formed at a connecting portion between the straight tubular portion 42 and the suction tubular portion 43 so as to project radially inward. The inside of the lower valve seat portion 45 is a communication hole 46 that connects the inside of the liquid cylinder 14 and the inside of the container body A.

  A tube body 47 for sucking up the contents in the container body A is fitted inside the suction cylinder portion 43. The tube body 47 extends, for example, to the vicinity of the bottom portion of the container body A, and the upper end portion contacts the lower valve seat portion 45 from below.

A lower valve body 50 that opens and closes the communication hole 46 is disposed in the straight tubular portion 42. The lower valve body 50 is a check valve that keeps the communication hole 46 closed when the liquid cylinder 14 is pressurized and opens the communication hole 46 when the liquid cylinder 14 is depressurized.
The lower valve body 50 is disposed on the valve body 51 that opens and closes the communication hole 46, the support cylinder portion 52 that is disposed on the lower valve seat portion 45 and supports the valve body 51, and is disposed above the valve body 51. And a support shaft portion 53 connected to the upper end portion of the support tubular portion 52.

The support tubular portion 52 is arranged coaxially with the axis O, and is fitted inside the straight tubular portion 42.
The valve main body 51 is formed in a disk shape in a plan view arranged coaxially with the axis O, and is seated on the lower valve seat portion 45 so as to be separable upward and closes the communication hole 46. A plurality of elastic supports which are arranged between the lower valve body 54 and the support tubular portion 52 at intervals in the circumferential direction and which support the lower valve body 54 elastically displaceable in the axis O direction with respect to the support tubular portion 52. The piece 55 is provided.

The elastic support piece 55 has an inner end portion integrally connected to the outer peripheral edge portion of the lower valve body 54, and an outer end portion integrally connected to the inner peripheral surface of the support tubular portion 52. The valve body 51 is a three-point valve including, for example, three elastic support pieces 55.
The support shaft portion 53 is formed in a cross shape in plan view, for example. As a result, the space inside the support cylinder portion 52 and the space located above the support shaft portion 53 inside the liquid cylinder 14 communicate with each other. A coil spring 56 that urges the stem 3 upward is externally inserted on the support shaft portion 53.

  The stem 3 is arranged coaxially with the axis O in the storage cylinder 10 and the liquid cylinder 14. The stem 3 is biased upward by receiving a spring force (biasing force) from the coil spring 56, and is also arranged so as to be able to move downward in accordance with the pushing operation of the push head 5. The stem 3 is formed in a tubular shape having an outer diameter smaller than the inner diameter of the storage tubular portion 20 and the inner diameter of the straight tubular portion 42, and larger than the outer diameter of a linking tubular portion 71 described later. The inside of the stem 3 communicates with the inside of the storage cylinder 10 and the inside of the liquid cylinder 14.

The discharge piston 13 is formed integrally with the stem 3. The discharge piston 13 is provided on the discharge cylinder portion 57 that is vertically slidably in contact with the inner peripheral surface of the storage cylinder portion 20 and on the discharge cylinder portion 57 so as to project radially outward from the upper end of the stem 3. And an annular connecting portion 58 connected to each other.
The upper end of the discharge cylinder 57 gradually increases in diameter from the connecting portion with the connecting portion 58 upward, and the lower end gradually increases in diameter from the connecting portion with the connecting portion 58 downward. As a result, the discharge piston 13 is in slidable contact with the inner peripheral surface of the storage cylinder portion 20 over the entire circumference thereof.

  On the top wall portion 22 of the storage cylinder 10, a plurality of restriction pieces 59 protruding downward are formed at intervals in the circumferential direction. The connecting portion 58 of the discharge piston 13 is in contact with the regulating piece 59 from below. As a result, the upward movement of the discharge piston 13 and the stem 3 is restricted, and the highest position is positioned as shown in FIG.

Since the discharge piston 13 is formed integrally with the stem 3 as described above, it moves up and down in cooperation with the stem 3. Therefore, when the discharge piston 13 moves downward together with the stem 3, the storage space S is defined in the storage cylinder 10 so as to be located above the discharge piston 13 as shown in FIG. As a result, the contents from the stem 3 can be stored in the storage cylinder 10 using the storage space S.
When the discharge piston 13 is restored and moved upward together with the stem 3, the discharge piston 13 transfers the content stored in the storage space S into the nozzle cylinder 12 through the through hole 25 so as to push the content out of the storage cylinder 10.

As shown in FIG. 1, the liquid piston 15 is arranged coaxially with the axis O and vertically slidably arranged in the straight cylindrical portion 42 of the liquid cylinder 14.
The liquid piston 15 is fitted inside the stem 3 and a liquid cylinder portion 60 that is vertically slidably in contact with the inner peripheral surface of the straight cylinder portion 42, and the lower end portion thereof is connected to the liquid cylinder portion 60. And a connecting tube portion 61.

The connecting cylinder portion 61 extends below the stem 3, and the outer peripheral surface at the lower end thereof is connected to the vertical middle portion of the liquid cylinder portion 60.
The upper opening end of the connecting tubular portion 61 is located below the lower opening end of the below-mentioned connecting tubular portion 71, and is arranged to face the lower opening end of the following tubular portion 71 with a gap. The lower open end of the connecting tubular portion 61 functions as the upper valve seat portion 62.

  The liquid cylinder portion 60 has its upper end portion gradually increasing in diameter as it goes upward from the connecting portion with the connecting tubular portion 61, and its lower end portion gradually increasing in diameter as going downward from the connecting portion with the connecting tubular portion 61. . As a result, the discharge piston 13 is in slidable contact with the inner peripheral surface of the straight tube portion 42 over the entire circumference thereof.

  Since the connecting cylinder 61 is fitted to the stem 3 as described above, the liquid piston 15 moves up and down in cooperation with the stem 3. Therefore, as the liquid piston 15 moves downward together with the stem 3, the liquid cylinder 14 can be pressurized, and the contents sucked up into the liquid cylinder 14 as shown in FIG. It can be transferred to the storage cylinder 10 side through the inside.

As shown in FIG. 1, the liquid cylinder portion 60 closes the second air hole 44 formed in the straight cylinder portion 42 from the inside in the radial direction when the stem 3 is located at the highest position. As shown in FIG. 3, when the liquid piston 15 moves downward along with the stem 3, the second air hole 44 is opened.
As a result, the interior of the container body A communicates with the outside through the second air hole 44 and the first air hole 23 from the time when the stem 3 moves downward until the time when the stem 3 restores to the original position (highest position).

As shown in FIG. 1, an upper valve body 65 is arranged in the liquid piston 15 so as to be vertically movable in a state of being arranged coaxially with the axis O.
The upper valve body 65 has an upper valve body 66 that is circular in plan view and is seated from below on the upper valve seat portion 62 of the connecting tubular portion 61, and extends upward from the upper valve body 66. And an insertion tube portion 67 that is inserted from below.

  The insertion tubular portion 67 projects upward from the connecting tubular portion 61 and is formed to have an outer diameter smaller than the inner diameter of the connecting tubular portion 61. Therefore, an annular first flow passage R1 is formed between the insertion cylinder portion 67 and the connection cylinder portion 61.

The upper valve body 66 is arranged inside the liquid cylinder portion 60 so as to be vertically slidable, and is seated on the upper valve seat portion 62 so as to be separable downward. A flow hole 68 that penetrates the upper valve body 66 in the direction of the axis O is formed in a part of the outer peripheral portion of the upper valve body 66.
A support wall 69 protruding downward is formed in the central portion of the upper valve body 66. The support wall 69 is formed to have a cross shape in plan view.

A coil spring 56 is arranged in a compressed state between the upper valve body 65 and the lower valve body 50. The lower end side of the coil spring 56 is externally inserted into the support shaft portion 53 of the lower valve body 50, and the upper end side thereof is externally inserted into the support wall 69, so that the upper valve body 65 and the lower valve body 50 are directed in the axis O direction. Are urged to separate from each other.
As a result, the upper valve body 65 is biased upward by the coil spring 56, and the upper valve body 66 is seated while being pressed against the upper valve seat portion 62.

Therefore, the communication between the inside of the first flow passage R1 and the inside of the liquid cylinder 14 is blocked by the upper valve body 66. On the other hand, as shown in FIG. 3, when the upper valve body 65 moves downward against the spring force (biasing force) of the coil spring 56, the upper valve body 66 separates downward from the upper valve seat portion 62. Therefore, the inside of the first flow passage R1 and the inside of the liquid cylinder 14 communicate with each other through the flow holes 68.
In this way, the upper valve body 65 shuts off the inside of the first flow passage R1 and the inside of the liquid cylinder 14 by utilizing the spring force of the coil spring 56, and moves downward due to the pressing operation of the pressing head 5, The first flow passage R1 and the liquid cylinder 14 are communicated with each other.

As shown in FIG. 1, the push-down head 5 includes a head portion 70 having a top wall portion and a peripheral wall portion, and a guide portion of the storage cylinder 10 that extends downward from the top wall portion of the head portion 70. The connecting cylinder portion 71 is inserted into the cylinder portion 21 from above, and the first mounting cylinder portion 73 that extends downward from the top wall portion of the head portion 70 and is located behind the linking cylinder portion 71. ing.
The head portion 70 is arranged above the storage cylinder 10 with a certain distance (stroke) from the storage cylinder 10. As a result, the push-down head 5 can be pushed down by a certain stroke.

  The linking cylinder portion 71 is supported by the guide cylinder portion 21 so as to be vertically movable, and is also inserted into the stem 3. The lower end portion of the linking cylinder portion 71 is fitted onto the insertion cylinder portion 67 of the upper valve body 65. As a result, the connecting cylinder portion 71 and the upper valve body 65 are integrally connected, and the upper valve body 65 can be moved up and down with the pressing head 5.

  As described above, since the inner diameter of the stem 3 is larger than the outer diameter of the linking tubular portion 71, the annular second flow passage R2 is formed between the linking tubular portion 71 and the stem 3. A gap is formed between the lower opening end of the linking cylinder portion 71 and the upper opening end of the connecting cylinder portion 61 of the liquid piston 15. As a result, the first flow passage R1 and the second flow passage R2 communicate with each other through this gap.

A plurality of projecting pieces 72, which project downward and are arranged at intervals in the circumferential direction, are formed at the lower opening end of the linking tubular portion 71. Therefore, when the linking cylinder portion 71 starts to move downward by pushing down the push-down head 5, the protruding piece 72 comes into contact with the upper opening end of the connecting cylinder portion 61 from above as shown in FIG.
Even in this case, the first flow passage R1 and the second flow passage R2 communicate with each other through the protrusion pieces 72 adjacent to each other in the circumferential direction.

  Further, since the upper valve body 65 moves downward together with the linking cylinder portion 71, when the protruding piece 72 contacts the upper open end of the connecting cylinder portion 61, the upper valve body 66 separates downward from the upper valve seat portion 62. To do. As a result, the inside of the first flow passage R1 and the inside of the liquid cylinder 14 communicate with each other through the flow holes 68. Therefore, the inside of the liquid cylinder 14 communicates with the inside of the storage cylinder 10 through the inside of the first flow passage R1 and the inside of the second flow passage R2.

Furthermore, after the protruding piece 72 contacts the upper open end of the connecting cylinder portion 61, when the linking cylinder portion 71 is further moved downward by pushing down the pressing head 5, the protruding piece 72 also pushes down the liquid piston 15. 15 and the stem 3 move downward together with the pressing head 5 and the upper valve body 65.
Therefore, the liquid piston 15 moves downward in the liquid cylinder 14, the internal volume of the liquid cylinder 14 decreases, and the internal pressure rises (pressurizes). Therefore, since the lower valve body 50 closes the communication hole 46, the content in the liquid cylinder 14 can be supplied to the storage cylinder 10 side through the first flow passage R1 and the second flow passage R2. Become.

Of the internal volume of the storage space S in the storage cylinder 10, the increased volume that increases with the downward movement of the discharge piston 13 decreases with the downward movement of the liquid piston 15 of the internal volume of the liquid cylinder 14. The volume is set to be equal to or larger than the volume to be used.
Specifically, the inner volume of the storage cylinder 10 can be adjusted by changing, for example, the outer diameter of the storage cylinder 20 or the length of the storage cylinder 20 (the length along the direction of the axis O). It is possible.

  The first mounting cylinder portion 73 is smaller than the linking cylinder portion 71 in the direction of the axis O. The first mounting cylinder portion 73 is open on the upper surface of the top wall portion of the head portion 70.

When the push-down head 5 is located at the highest position, the lower end of the main body 81 is arranged at the same position as the nozzle cylinder 12 in the direction of the axis O and faces the storage cylinder 10 in the front-rear direction. A locking hole 81a is formed at the lower end of the main body 81 to penetrate the main body 81 in the front-rear direction.

  The operation portion 82 is formed so that it can be pushed in by a human hand. In the present embodiment, the operation unit 82 can be pushed in from the front of the operation unit 82. The operation portion 82 is formed in a plate shape whose front and back surfaces face the front-rear direction. The operating portion 82 is inclined so as to gradually move rearward from the lower side toward the upper side in a side view of the dispenser 1 viewed from the left and right directions.

  The operation portion 82 is arranged in front of the storage cylinder 10 and behind the third nozzle cylinder 32. The operation portion 82 is arranged below the first nozzle cylinder 30. When the push-down head 5 is located at the highest position, the upper end of the operating portion 82 is locked to the nozzle cylinder 12 from below. As a result, further upward movement of the push head 5 is restricted.

  The connecting portion 83 connects the main body portion 81 and the operating portion 82. A pair of connecting portions 83 are provided at intervals in the left-right direction. As shown in FIG. 2, the pair of connecting portions 83 sandwich the storage cylinder 10 and the nozzle cylinder 12 from the left-right direction. Each connecting portion 83 extends in the front-rear direction. The rear end of the connecting portion 83 is connected to the lower end of the main body 81, and the front end of the connecting portion 83 is connected to the upper end of the operating portion 82.

The connecting portion 83 includes a curved portion 83a located on the rear side and a straight portion 83b located on the front side. The curved portion 83a faces the storage cylinder 10 in the left-right direction. The curved portion 83a is curved so as to project outward in the left-right direction. The straight portion 83b extends straight from the front end of the curved portion 83a along the front-rear direction.
As shown in FIG. 1, when the pressing head 5 is located at the highest position, the connecting portion 83 (straight portion 83b) faces the nozzle cylinder 12 (first nozzle cylinder 30) in the left-right direction. As shown in FIGS. 3 and 4, when the push-down head 5 descends from the highest position, the rear end of the connecting portion 83 (straight portion 83b) faces the regulation plate 16 in the left-right direction.

As shown in FIG. 1, the holding portion 6 further includes an upper locking portion 84 and a lower locking portion 85.
The upper locking portion 84 is linked to the vertical movement of the pressing head 5. The upper locking portion 84 is provided on the movable body 80. The upper locking portion 84 is formed by the lower end portion of the main body portion 81.

  The lower locking portion 85 is not linked to the vertical movement of the push head 5. The lower locking portion 85 is arranged below the upper locking portion 84. The lower locking portion 85 is provided on the storage cylinder 10. The lower locking portion 85 projects rearward from the storage tubular portion 20. The upper surface of the lower locking portion 85 is a lower guide surface 85a that guides the sliding of the upper locking portion 84. The lower guide surface 85a is inclined downward as it goes rearward.

  As shown in FIG. 3, when the pressing head 5 is located at the lowest position, the upper locking portion 84 and the lower locking portion 85 are locked to each other, so that the holding portion 6 moves upward of the pressing head 5. Regulate. In this embodiment, the lower locking portion 85 is fitted in the locking hole 81a, and the upper locking portion 84 and the lower locking portion 85 are locked to each other in the axis O direction. As a result, the pressing head 5 is held at the lowest position against the upward biasing force from the coil spring 56 (stem 3).

  As shown in FIG. 1, the restricting portion 7 restricts the relative movement of the upper engaging portion 84 and the lower engaging portion 85 in the circumferential direction. The regulating portion 7 regulates the circumferential movement of the push-down head 5 to regulate the relative movement of the upper locking portion 84 and the lower locking portion 85 in the circumferential direction.

  The regulation unit 7 includes a first regulation unit 91 and a second regulation unit 92. The first restriction portion 91 is linked to the vertical movement of the push head 5, and the second restriction portion 92 is not linked to the vertical movement of the push head 5. The first restricting portion 91 and the second restricting portion 92 engage with each other in the circumferential direction, so that the restricting portion 7 restricts the rotation of the pressing head 5. In this embodiment, the first restricting portion 91 is formed by the movable body 80, and the second restricting portion 92 is formed by the nozzle cylinder 12 and the restricting plate 16.

  When the pressing head 5 is located at the highest position, the connecting portion 83 (first restricting portion 91) is circumferentially locked to the nozzle cylinder 12 (second restricting portion 92) to restrict the rotation of the pressing head 5. To do. As shown in FIG. 3 and FIG. 4, when the push-down head 5 descends from the highest position, the connecting portion 83 (first regulation portion 91) is locked to the regulation plate 16 (second regulation portion 92) in the circumferential direction. Thus, the rotation of the pressing head 5 is restricted.

(Use of dispenser)
Next, the case of using the above-described dispenser 1 will be described. The contents are taken up from the container body A into the liquid cylinder 14.

When discharging the content, as shown in FIG. 3, the head portion 70 is pushed down against the spring force of the coil spring 56, and the entire pushing head 5 is moved downward. As a result, the linking cylinder portion 71 begins to move downward while being supported by the guide cylinder portion 21, so that the protruding piece 72 comes into contact with the upper opening end of the connecting cylinder portion 61 of the liquid piston 15 from above. Further, since the upper valve body 65 starts to move downward along with the linking cylinder portion 71, the upper valve body 66 separates downward from the upper valve seat portion 62 of the liquid piston 15.
Therefore, the inside of the liquid cylinder 14 and the inside of the first flow passage R <b> 1 are in communication with each other through the flow holes 68.

  Then, since the projection piece 72 pushes down the liquid piston 15 by further pushing down the pushing head 5, as shown in FIG. 3, the pushing head 5 and the upper valve body 65 are pushed together with the liquid piston 15 and the stem 3. It can be moved downward at the same time. At this time, the pressing head 5, the upper valve body 65, the liquid piston 15 and the stem 3 are moved downward while maintaining the state where the upper valve body 66 is separated downward from the upper valve seat portion 62 of the liquid piston 15. You can

Then, since the liquid piston 15 moves downward in the liquid cylinder 14, the internal volume of the liquid cylinder 14 gradually decreases and the internal pressure rises (pressurizes). As a result, the lower valve body 50 closes the communication hole 46. Further, since the liquid piston 15 pushes out the content in the liquid cylinder 14, the content is passed through the stem 3 (specifically, through the flow hole 68, the first flow passage R1 and the second flow passage R2). , Can be supplied to the storage cylinder 10 side.
Thereby, the contents from the stem 3 can be temporarily stored in the storage cylinder 10 using the storage space S.

  When the push-down head 5 is pushed down by, for example, a stroke and the stem 3 is lowered to the lowest position, the upper locking portion 84 and the lower locking portion 85 are in sliding contact with each other while the upper locking portion 84 and the lower locking portion 84 are in contact with each other. At least one of the locking portions 85 is elastically displaced, and the upper locking portion 84 and the lower locking portion 85 lock with each other. At this time, in the present embodiment, the lower end edge of the upper locking portion 84 (the lower end edge of the main body portion 81) slides on the lower guide surface 85a, whereby the main body portion 81 elastically deforms rearward, The locking portion 84 is elastically displaced rearward. Then, when the lower locking portion 85 crosses over the portion of the upper locking portion 84 located below the locking hole 81a in the direction of the axis O, the main body portion 81 is restored and deformed forward, and the upper locking portion. 84 is restored and displaced toward the front. As a result, the lower locking portion 85 is fitted into the locking hole 81a, and the holding portion 6 holds the push-down head 5 at the lowest position. At this time, the operating portion 82 is arranged below the discharge hole 11.

  Here, the holding unit 6 releases the holding of the push head 5 when the operation unit 82 is operated. In the present embodiment, when the operating portion 82 is pushed in, the upper locking portion 84 is elastically displaced in association with the operating portion 82, so that the locking between the upper locking portion 84 and the lower locking portion 85 is released. Then, the holding of the pressing head 5 is released. When the operating portion 82 is pushed rearward, the pressing force applied to the operating portion 82 is transmitted to the main body portion 81 via the connecting portion 83, and the main body portion 81 elastically deforms rearward. As a result, the lower side locking portion 85 is disengaged from the locking hole 81a, the upper side locking portion 84 and the lower side locking portion 85 are unlocked, and the holding portion 6 releases the holding of the pressing head 5. It

When the holding of the push-down head 5 by the holding portion 6 is released, the upper valve body 65 is pushed up by the upward biasing force (elastic restoring force) of the coil spring 56. Therefore, as shown in FIG. 4, since the upper valve body 65 and the pressing head 5 are restored and moved upward, they are moved upward relative to the liquid cylinder 14 and the stem 3.
Therefore, the upper valve body 66 of the upper valve body 65 is seated on the upper valve seat portion 62 of the liquid piston 15 from below, and the projecting piece 72 of the linking cylinder portion 71 of the connecting cylinder portion 61 of the liquid piston 15 is arranged. Separated upward from the upper open end. Particularly, when the upper valve body 66 is seated on the upper valve seat portion 62, the communication between the liquid cylinder 14 and the first flow passage R1 is cut off.

In addition, when the upper valve body 66 is seated on the upper valve seat portion 62, the liquid valve piston 15 and the stem 3 are integrally restored and moved upward together with the upper valve body 65 and the pressing head 5.
Therefore, as the stem 3 is restored and moved, the discharge piston 13 moves upward in the storage cylinder 10, so that the contents stored in the storage cylinder 10 are pushed out from the storage cylinder 10 through the through holes 25. It can be supplied into the cylinder 12. As a result, the contents can be discharged to the outside through the discharge holes 11.

  Further, as the liquid piston 15 moves upward in the liquid cylinder 14, the liquid cylinder 14 is depressurized to a negative pressure state, so that the lower valve body 50 opens the communication hole 46. As a result, the contents in the container body A can be sucked up into the liquid cylinder 14 through the tube body 47, and can be prepared for the next discharge.

  Since the second air hole 44 is opened as shown in FIGS. 3 and 4 from the time when the stem 3 and the liquid piston 15 move downward to the time when the stem 3 and the liquid piston 15 return to their original positions, the container body A The inside communicates with the outside through the second air hole 44 and the first air hole 23. Therefore, the air in the container body A can be replaced, and even if the contents are sucked up from the container body A into the liquid cylinder 14, the inside of the container body A can be prevented from being decompressed. Therefore, it is possible to perform a smooth restoration movement of the pressing head 5 and a smooth discharge of the contents.

  As described above, according to the dispenser 1 of the present embodiment, the contents can be temporarily stored in the storage cylinder 10, so that the contents are discharged when the stem 3 is moved downward by the pressing operation of the pressing head 5. It is possible to prevent the contents from being discharged, and thereafter, when the stem 3 is restored and moved upward, the contents can be discharged.

  Therefore, the discharged contents can be received not only by one hand but also by both hands. Furthermore, for example, even when one hand is blocked for some reason (for example, when holding a child or when carrying luggage), only the other hand can be used to discharge the contents ( That is, it is possible to perform the pressing operation of the pressing head 5) and to receive the discharged contents. Therefore, it is very easy to use and convenience can be improved.

  Moreover, when the content is temporarily stored in the storage cylinder 10 and the push head 5 is lowered to the lowest position, the holding unit 6 can hold the push head 5 at the lowest position. Therefore, when the pressing head 5 is released and the hand is released from the pressing head 5, it is possible to prevent the pressing head 5 and the stem 3 from rising and discharging the contents. Therefore, it is possible to discharge the contents by moving the operation part 82 after the hand separated from the pressing head 5 is brought close to the nozzle cylinder 12 to raise the pressing head 5 and the stem 3. Further, for example, after the ejection is completed, the pressing head 5 is lowered for the next ejection, and the holding portion 6 holds the pressing head 5 at the most lowered position, so that the next ejection can be smoothly performed. Therefore, the convenience can be further improved.

  Further, when the push-down head 5 descends toward the lowest position, the upper locking portion 84 and the lower locking portion 85 are in sliding contact with each other, and the upper locking portion 84 and the lower locking portion 85 are At least one of them is displaced and the upper locking portion 84 and the lower locking portion 85 are locked to each other, so that the holding portion 6 restricts the upward movement of the push head 5. Therefore, by performing the work of lowering the pressing head 5 toward the lowest position, the holding unit 6 can hold the pressing head 5 at the lowest position. Thereby, convenience can be further improved.

  Further, the regulation portion 7 regulates the relative movement of the upper locking portion 84 and the lower locking portion 85 in the circumferential direction. Therefore, when the push-down head 5 descends toward the lowest position, the upper locking portion 84 and the lower locking portion 85 can be positioned relative to each other in the circumferential direction and can be reliably locked.

  In addition, the nozzle cylinder 12 extends forward from the storage cylinder 10 side, and the operation portion 82 is arranged in front of the storage cylinder 10. Therefore, immediately after the operating portion 82 is manually operated to release the holding of the pressing head 5 by the holding portion 6, the hand can be brought close to the nozzle cylinder 12. Thereby, convenience can be further improved.

  Further, when the push-down head 5 is located at the lowest position, the operation portion 82 is arranged below the ejection hole 11. Therefore, immediately after the operating portion 82 is manually operated to release the holding of the pressing head 5 by the holding portion 6, the hand can be positioned below the ejection hole 11. Thereby, convenience can be further improved.

Further, in this embodiment, since the liquid cylinder 14 and the liquid piston 15 are provided, the contents sucked up in the liquid cylinder 14 can be stored in the storage cylinder 10.
Therefore, it is easy to regulate the amount of the content discharged by one discharge operation by the inner volume of the liquid cylinder 14, and for example, it is easy to discharge a fixed amount of the content.

Moreover, the increased volume of the internal volume of the storage space S in the storage cylinder 10 that increases with the downward movement of the discharge piston 13 decreases with the downward movement of the liquid piston 15 of the internal volume of the liquid cylinder 14. Since the volume is equal to or more than the volume, it is possible to prevent the amount of contents exceeding the internal volume of the storage cylinder 10 from being supplied into the storage cylinder 10 when the stem 3 is moved downward.
Therefore, when the stem 3 moves downward, the contents can be reliably stored in the storage cylinder 10, and it is difficult for the contents to flow from the storage cylinder 10 into the nozzle cylinder 12. Therefore, it is easy to effectively prevent the contents from leaking from the discharge hole 11 when the stem 3 moves downward.

  Furthermore, the nozzle cylinder 12 is integrally connected to the storage cylinder 10 that is a fixed member, and is configured separately from the pressing head 5 that is a movable member. Therefore, the nozzle cylinder 12 can be used without moving, and the contents can be discharged from the discharge hole 11 fixed at a fixed position. Therefore, the discharged contents can be easily received, and the usability can be improved.

Thereby, even if the push-down head 5 rotates in the circumferential direction, the upper locking portion 84 and the lower locking portion 85 can be opposed to each other in the axis O direction.

(Use of dispenser)
As shown in FIG. 13, when the pressing head 5 is lowered to the lowest position in the ejector 110, the upper guide surface 84a slides on the lower guide surface 85a, so that the elastic piece 117 is attached to the main body 81. While being elastically deformed with the cap 2, the movable body 80 swings around the swing axis L, and the upper locking portion 84 is elastically displaced forward. When the upper locking portion 84 crosses over the lower locking portion 85 in the direction of the axis O, the elastic piece 117 is restored and deformed to urge the movable body 80 around the swing axis L, and the upper locking portion 84 moves rearward. It is restored and displaced toward. As a result, the upper end of the upper locking portion 84 is locked to the lower end of the lower locking portion 85 from below, and the holding portion 6 holds the pressing head 5 at the lowest position. At this time, the operating portion 82 is arranged below the discharge hole 11.

  When the holding of the push-down head 5 is released, the operation portion 82 is pushed backward. Then, the pressing force applied to the operating portion 82 is transmitted to the body portion 81 via the connecting portion 83, and the body portion 81 swings around the swing axis L while the elastic piece 117 elastically deforms. As a result, the engagement between the upper engagement portion 84 and the lower engagement portion 85 is released, and the holding of the pressing head 5 by the holding portion 6 is released.

  As described above, according to the ejector 110 of the present embodiment, it is possible to achieve the same effects as the first embodiment.

  The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the pump mechanism including the liquid cylinder and the liquid piston is adopted as the discharge mechanism, but the present invention is not limited to this case. For example, an aerosol mechanism may be adopted in which the content is filled in the container body in a compressed state and the content is ejected from the stem by pushing down the stem. Even in this case, since the contents from the stem can be temporarily stored in the storage cylinder, it is possible to achieve the same effect as the present embodiment.

  In the above-described embodiment, the lower valve body 50 is provided in the liquid cylinder 14, and when the liquid piston 15 moves downward in the liquid cylinder 14 together with the stem 3, the lower valve body 50 causes the liquid cylinder 14 and the container body to move. By shutting off the communication with A, the inside of the liquid cylinder 14 is pressurized, whereby the contents in the liquid cylinder 14 are supplied to the storage cylinder 10. However, the present invention is not limited to this. For example, an opening / closing valve is provided in the nozzle cylinder 12, the opening / closing valve blocks the communication between the storage cylinder 10 and the discharge hole 11 when the pressure in the storage cylinder 10 is reduced, and the lower valve body is the storage cylinder 10 when the pressure in the storage cylinder 10 is increased. It is also possible to adopt a configuration in which the discharge hole 11 and the discharge hole 11 communicate with each other. In this case, when the discharge piston 13 moves downward in the storage cylinder 10 together with the stem 3, the opening / closing valve blocks the communication between the storage cylinder 10 and the discharge hole 11, and the inside of the storage cylinder 10 is depressurized. Thereby, the contents in the liquid cylinder 14 can be supplied to the storage cylinder 10.

  In the above embodiment, when the push-down head 5 descends to the lowest position, at least one of the upper locking portion 84 and the lower locking portion 85 elastically displaces, and the upper locking portion 84 and the lower locking portion 85 move. The stops 85 are locked to each other. However, the present invention is not limited to this. For example, when the upper locking portion 84 and the lower locking portion 85 are locked with each other, the upper locking portion 84 and the lower locking portion 85 do not necessarily have to be elastically displaced, and an elastic restoring force is not required. It may be displaced without receiving it.

  In the above embodiment, the ejector 1 ejects the content in a liquid state, but the present invention is not limited to this. For example, the present invention can be applied to a discharger that discharges the contents in the form of bubbles. For example, the dispenser is vertically movable in association with the liquid cylinder that is in communication with the stem and the liquid cylinder, and is vertically slidably disposed in the liquid cylinder. As the stem moves downward, the liquid cylinder is moved. A liquid piston for supplying the contents inside into the stem, and an air cylinder in which an air piston linked to the stem is vertically slidably housed are provided. A gas-liquid mixing chamber that mixes the supplied contents and the air supplied from the air cylinder, and in a state where the contents are foamed by foaming the gas-liquid mixture mixed in the gas-liquid mixing chamber, The present invention can also be applied to a configuration in which a foam member to be supplied into the storage cylinder is provided.

  In the above embodiment, the discharge hole 11 is formed at the front end portion of the nozzle cylinder 12, but the present invention is not limited to this. For example, the discharge hole 11 may be formed in the middle portion of the nozzle cylinder 12 in the front-rear direction.

When the push-down head 5 is located at the lowermost position, the operation portion 82 does not have to be arranged below the ejection hole 11.
The operation unit 82 may not be arranged in front of the storage cylinder 10.
In the first embodiment and the second embodiment described above, the regulation portion 7 may be omitted.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with known constituent elements within the scope of the present invention, and it is also possible to appropriately combine the modified examples.
