JP 2012-232228 A

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

  The present invention has been made in view of such circumstances. The purpose of the present invention is to receive the discharged contents with both hands, as well as to discharge the contents and to receive the discharged contents. It is providing the discharge device which can be performed only with one hand.

In order to solve the above problems, the present invention proposes the following means.
A discharger according to the present invention includes a stem that is disposed in an upwardly biased state at a mouth portion of a container main body in which contents are accommodated, and that accommodates the stem in a vertically movable manner, A storage cylinder that stores the contents from the stem that accompanies the downward movement of the stem, a nozzle cylinder that communicates with the storage cylinder and has a discharge hole for discharging the contents, and the stem The discharge piston disposed in the storage cylinder so as to be vertically slidable, the pressing head that moves up and down in conjunction with the stem, and the pressing head is held at the lowest position. A holding portion, and the holding portion includes an upper locking portion that is linked to the vertical movement of the pressing head, an operation portion that covers the nozzle cylinder and is swingable about a swing shaft, When provided in the operation unit A lower locking portion disposed below the upper locking portion, and the upper locking portion and the lower locking portion when the pressing head is lowered toward the lowest position. Slidably contacting each other, the lower locking portion is displaced with the swing of the operation portion, and the upper locking portion and the lower locking portion are locked to each other, so that the holding portion is The upward movement of the pressing head is restricted, and the holding portion releases the locking of the upper locking portion and the lower locking portion when the operation portion is operated and swings to release the pressing head. Release the holding.

According to the present invention, the discharge piston can be moved downward in the storage cylinder by pressing the pressing head and moving the stem downward with respect to the storage cylinder, and the contents from the stem can be moved into the storage cylinder. Once stored. Further, when the pressing head is lowered to the lowest position, the holding head can hold the pressing head at the lowest position. At this time, while the upper locking portion and the lower locking portion are in sliding contact with each other, the lower locking portion is displaced with the swing of the operation portion, so that the upper locking portion and the lower locking portion are mutually moved. Lock.
After that, when the operating part is operated to swing, the upper locking part and the lower locking part are unlocked, and the holding of the pressing head by the holding part is released, the stem is restored and moved upward by the upward biasing force. To do. Therefore, the discharge piston moves upward in the storage cylinder in accordance with the restoring movement of the stem, and supplies the contents stored in the storage cylinder into the nozzle cylinder so as to push out the contents from the storage cylinder. Thereby, the contents can be discharged to the outside through the discharge holes.

Thus, since the contents can be temporarily stored in the storage cylinder, the contents can be prevented from being discharged when the stem is moved downward by a push-down operation or the like, and then the stem is restored and moved upward. Sometimes the contents can be discharged.
Therefore, the discharged contents can be received not only with one hand but also with both hands. Furthermore, even if one hand is blocked for some reason (for example, when holding a child or holding a baggage), the contents can be discharged and operated with only the other hand. The discharged contents can be received. Therefore, it is very easy to use and the convenience can be improved.
Moreover, when the contents are once stored in the storage cylinder and the pressing head is lowered to the lowest position, the pressing head can be held at the lowest position by the holding portion. Therefore, when the pressing of 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, after the hand released from the pressing head approaches the nozzle cylinder, the operation unit can be operated to raise the pressing head and stem to discharge the contents. Further, for example, after the discharge is completed, the next discharge can be smoothly performed by lowering the pressing head for the next discharge and holding the pressing head at the lowest position by the holding unit. Therefore, convenience can be further improved.
Further, when the pressing head is lowered toward the lowest position, the lower locking portion is displaced with the swing of the operation portion while the upper locking portion and the lower locking portion are in sliding contact with each other, The upper locking part and the lower locking part lock each other, so that the holding part regulates the upward movement of the pressing head. Accordingly, by performing the operation of lowering the pressing head toward the lowest position, the pressing head can be held at the lowest position by the holding portion. Thereby, the convenience can be further improved.
Furthermore, since the operation unit covers the nozzle cylinder, it is possible to suppress the discharge device from being bulky and to make the discharge device compact.

  The nozzle cylinder and the operation portion may extend forward from the storage cylinder side, and a front end portion of the operation portion may be disposed forward of the swing shaft.

  In this case, the nozzle cylinder and the operation portion extend forward from the storage cylinder side, and the front end portion of the operation portion is disposed forward of the swing shaft. Therefore, immediately after releasing the holding of the pressing head by the holding part by operating the operating part so that the front part of the operating part is moved up and down by hand and the operating part swings, the hand is brought close to the nozzle cylinder. I can leave. Thereby, the convenience can be further improved.

  A front end portion of the operation portion may be disposed below the discharge hole.

  In this case, the front end portion of the operation portion is disposed below the discharge hole. Therefore, immediately after the front end portion of the operation portion is operated by hand and the holding of the pressing head by the holding portion is released, the hand can be positioned below the discharge hole. Thereby, the convenience can be further improved.

  The lower locking portion may be disposed behind and above the swing shaft.

  In this case, the lower locking portion is disposed behind and above the swing shaft. Therefore, the lower locking portion can be moved rearward and downward by moving the front end portion of the operation portion upward. Therefore, in a state where the upper locking portion and the lower locking portion are locked with each other, the lower locking portion is easily detached from the upper locking portion by moving the front end portion of the operation portion upward. be able to.

  A liquid cylinder communicating with the stem; and vertically moving in conjunction with the stem; and being slidable vertically within the liquid cylinder; and in the liquid cylinder as the stem moves downward A liquid piston for supplying the contents of the liquid 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 association with the stem. Thereby, the contents in the liquid cylinder can be supplied into the storage cylinder through the stem. Accordingly, the discharge amount of the content discharged by one discharge operation can be easily defined by the internal volume of the liquid cylinder, and for example, a fixed amount of the content can be discharged.

  The increased volume that increases with the downward movement of the discharge piston among the internal volume of the storage cylinder is equal to or larger than the volume that decreases with the downward movement of the liquid piston among the internal volume of the liquid cylinder. May be.

  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 the contents hardly flow into the nozzle cylinder from the storage cylinder. Therefore, it is easy to effectively prevent the contents from leaking from the discharge hole when the stem moves downward.

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

An annular top wall portion 22 that connects the guide tube portion 21, the upper end portion of the storage tube portion 20 and the lower end portion of the guide tube portion 21, and the guide tube portion 21 that is erected on the top wall portion 22 in the radial direction. And a surrounding cylinder portion 27 that surrounds from the outside.

  A connection portion between the storage cylinder portion 20 and the top wall portion of the mounting cap 2 is formed with a first air hole 23 that communicates the inside and the outside of the storage cylinder portion 20. The guide cylinder part 21 is formed so that the inner diameter is smaller than the inner diameter of the stem 3, and a link cylinder part 71 (described later) of the pressing head 5 is inserted inside the guide cylinder part 21 so as to be movable up and down.

  An annular seal portion 24 slidably in contact with the outer peripheral surface of the linkage tube portion 71 is projected downward from the connection portion between the guide tube portion 21 and the top wall portion 22. Thereby, the space | interval between the linkage cylinder part 71 and the seal part 24 is sealed tightly.

The nozzle cylinder 12 extends forward from the storage cylinder 10 side. Hereinafter, among the radial directions, 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-rear direction is the left-right direction.
The nozzle cylinder 12 is connected to the first nozzle cylinder 30 formed integrally with the guide cylinder portion 21 of the storage cylinder 10, the second nozzle cylinder 31 connected to the first nozzle cylinder 30, and the second nozzle cylinder 31. The third nozzle cylinder 32 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 part 21 and penetrate the surrounding cylinder part 27, and a part of the first nozzle cylinder 30 is formed integrally with the top wall part 22. . A portion of the top wall portion 22 formed integrally with the first nozzle cylinder 30 is formed with a through hole 25 penetrating the top wall portion 22 up and down. Thereby, 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 protrudes radially outward from the mounting cap 2, and the tip side is a small diameter cylinder portion 30 a having a smaller outer diameter than the other portions 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 an intermediate portion is bent obliquely downward and forward. The distal end side of the second nozzle cylinder 31 is a small-diameter cylinder part 31 a having a smaller outer diameter than other parts of the second nozzle cylinder 31.

The third nozzle cylinder 32 is fitted on the small diameter cylinder portion 31a of the second nozzle cylinder 31, and the discharge hole 11 is formed at the tip thereof. In the example shown in the drawing, the discharge hole 11 is formed in a tapered shape in a longitudinal section and opens downward.
In 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 disposed. The core body 33 has an outer diameter that is smaller than the inner diameters of the second nozzle cylinder 31 and the third nozzle cylinder 32, and is disposed with a slight gap between the core body 33 and the discharge hole 11. Thus, 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 hole 11 to the outside.

  In the illustrated example, the nozzle cylinder 12 is formed in an L shape when viewed from the side, but is not limited to this case, and is formed, for example, in a straight shape extending radially outward from the storage cylinder 10. It does not matter. Moreover, a top-end cylindrical nozzle tip may be attached to the tip of the core body 33 and the contents may be ejected, for example, in a mist form.

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

A second air hole 44 that penetrates the straight tube portion 42 in the radial direction 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 main body A and the inside of the liquid cylinder 14 communicate with each other through the second air hole 44.
An annular lower valve seat portion 45 projecting inward in the radial direction is formed at a connection portion between the straight tube portion 42 and the suction tube portion 43. The inside of the lower valve seat portion 45 is a communication hole 46 that allows the inside of the liquid cylinder 14 and the inside of the container main body A to communicate with each other.

  A tube body 47 that sucks up the contents in the container main 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 main 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 tube 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 that opens the communication hole 46 when the liquid cylinder 14 is depressurized.
The lower valve body 50 is disposed on the valve main body 51 that opens and closes the communication hole 46, the lower valve seat portion 45, the support cylinder portion 52 that supports the valve main body 51, and the valve main body 51. And a support shaft portion 53 connected to the upper end portion of the support cylinder portion 52.

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

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 cylinder 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, for example, in a cross shape in plan view. Thereby, the space in the support cylinder part 52 and the space located above the support shaft part 53 in the liquid cylinder 14 communicate with each other. A coil spring 56 that biases the stem 3 upward is externally inserted into the support shaft portion 53.

  The stem 3 is disposed 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 disposed so as to be able to move downward as the pressing head 5 is pushed down. The stem 3 is formed in a cylindrical shape having an outer diameter smaller than the inner diameter of the storage cylinder part 20 and the inner diameter of the straight cylinder part 42 and larger than the outer diameter of the linkage cylinder part 71 described later. The inside of the stem 3 communicates with the storage cylinder 10 and the liquid cylinder 14.

The discharge piston 13 is formed integrally with the stem 3. The discharge piston 13 is provided so as to protrude from the upper end portion of the stem 3 toward the radially outer side, in contact with the inner peripheral surface of the storage cylinder portion 20 so as to be vertically slidable. And an annular connecting portion 58 connected to each other.
The discharge cylinder portion 57 gradually increases in diameter as the upper end portion moves upward from the connection portion with the connecting portion 58, and the lower end portion gradually increases in diameter as moving downward from the connection portion with the connecting portion 58. Thus, the discharge piston 13 is in slidable contact with the inner peripheral surface of the storage cylinder portion 20 over the entire circumference.

  A plurality of regulating pieces 59 projecting downward are formed on the top wall portion 22 of the storage cylinder 10 at intervals in the circumferential direction. The connecting portion 58 of the discharge piston 13 is in contact with the restriction piece 59 from below. As a result, the upward movement of the discharge piston 13 and the stem 3 is restricted, and the most elevated 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 conjunction with the stem 3. Therefore, when the discharge piston 13 moves downward together with the stem 3, a storage space S is defined in the storage cylinder 10 so as to be positioned above the discharge piston 13 as shown in FIG. Thereby, it becomes possible to store the contents from the stem 3 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 is transferred into the nozzle cylinder 12 through the through hole 25 so as to push out the contents stored in the storage space S from the storage cylinder 10.

As shown in FIG. 1, the liquid piston 15 is disposed coaxially with the axis O and is slidable in the vertical cylinder portion 42 of the liquid cylinder 14.
The liquid piston 15 is fitted inside the stem 3 with the liquid cylinder part 60 slidably contacted with the inner peripheral surface of the straight cylinder part 42, and the lower end part thereof is connected to the liquid cylinder part 60. A connecting cylinder 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 middle portion of the liquid cylinder portion 60 in the vertical direction.
The upper opening end of the connecting cylinder portion 61 is positioned below the lower opening end of the linkage cylinder portion 71 described later, and is disposed so as to face the lower opening end of the linkage cylinder portion 71 with a gap. The lower opening end of the connecting cylinder portion 61 functions as the upper valve seat portion 62.

  The liquid cylinder part 60 gradually increases in diameter as the upper end part moves upward from the connection part with the connection cylinder part 61, and the lower end part gradually increases in diameter as it goes downward from the connection part with the connection cylinder part 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.

  Since the connecting cylinder portion 61 is fitted to the stem 3 as described above, the liquid piston 15 moves up and down in conjunction with the stem 3. Accordingly, the liquid piston 15 can move downward together with the stem 3 to pressurize the liquid cylinder 14, and the contents sucked up in the liquid cylinder 14 can be passed through the stem 3 to the storage cylinder 10 side. Can be transported.

  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. 2, when the liquid piston 15 moves downward along with the stem 3, the second air hole 44 is opened. Thus, the interior of the container body A communicates with the outside through the second air holes 44 and the first air holes 23 until the stem 3 is moved downward and restored to the original position (the highest position).

As shown in FIG. 1, an upper valve body 65 is disposed in the liquid piston 15 so as to be movable up and down in a state where it is disposed coaxially with the axis O.
The upper valve body 65 has an upper valve body 66 having a circular shape in plan view that is seated from below with respect to the upper valve seat part 62 of the connecting cylinder part 61, and extends upward from the upper valve body 66. And an insertion tube portion 67 inserted from below.

  The insertion cylinder part 67 protrudes upward from the connection cylinder part 61 and has an outer diameter smaller than the inner diameter of the connection cylinder part 61. Therefore, an annular first flow passage R <b> 1 is formed between the insertion tube portion 67 and the connection tube portion 61.

The upper valve body 66 is disposed inside the liquid cylinder portion 60 so as to be slidable in the vertical direction, and is seated so as to be separated from the upper valve seat portion 62 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 edge of the upper valve body 66.
A support wall 69 projecting downward is formed at the central portion of the upper valve body 66. The support wall 69 is formed in a cross shape in plan view.

A coil spring 56 is disposed in a compressed state between the upper valve body 65 and the lower valve body 50. The coil spring 56 has its lower end portion extrapolated to the support shaft 53 of the lower valve body 50 and its upper end portion extrapolated to the support wall 69, and the upper valve body 65 and the lower valve body 50 are connected in the direction of the axis O. Are urged to be separated from each other.
Accordingly, 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 first flow passage R1 and the liquid cylinder 14 is blocked by the upper valve body 66. On the other hand, as shown in FIG. 2, when the upper valve body 65 moves downward against the spring force (biasing force) of the coil spring 56, the upper valve body 66 is separated 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 hole 68.
As described above, the upper valve body 65 blocks the first flow passage R1 and the liquid cylinder 14 by using 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.

As shown in FIG. 1, the pressing head 5 has a plate-like head portion 70 whose front and back surfaces are directed in the direction of the axis O, and extends downward from the head portion 70, and is upward in the guide cylinder portion 21 of the storage cylinder 10. And a connecting cylinder portion 71 inserted from the above.
The head unit 70 is disposed above the storage cylinder 10 with a certain interval (stroke) from the storage cylinder 10. As a result, the pressing head 5 can be pressed down by a certain stroke.

  The linkage cylinder 71 is supported by the guide cylinder 21 so as to be movable up and down, and is also inserted into the stem 3. The lower end part of the linkage cylinder part 71 is fitted on the insertion cylinder part 67 of the upper valve body 65. As a result, the linking 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 cylinder portion 71, an annular second flow passage R <b> 2 is formed between the linking cylinder 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 in the liquid piston 15. Thus, the first flow path R1 and the second flow path R2 communicate with each other through this gap.

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

  Since the upper valve body 65 moves downward together with the linking cylinder portion 71, the upper valve body 66 moves away from the upper valve seat portion 62 downward when the protruding piece 72 comes into contact with the upper opening end of the connection cylinder portion 61. 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 hole 68. Therefore, the liquid cylinder 14 communicates with the storage cylinder 10 through the first flow path R1 and the second flow path R2.

Further, after the projecting piece 72 comes into contact with the upper opening end of the connecting cylinder portion 61, when the linkage cylinder portion 71 moves further downward by the depression of the pressing head 5, the liquid piston 15 is also pushed down by the projecting piece 72, and the liquid piston 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 is reduced, and the internal pressure is increased (pressurized). Accordingly, since the lower valve body 50 closes the communication hole 46, the contents 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, for example, the internal volume of the storage cylinder 10 can be adjusted by changing the outer diameter of the storage cylinder part 20 or the length of the storage cylinder part 20 (length along the axis O direction). Is possible.

In the present embodiment, the discharger 1 further includes a holding unit 6 and an urging member 7.
The holding unit 6 holds the pressing head 5 in the lowest position as shown in FIG.

It fits in the shaft hole 89. At this time, the nozzle cylinder 12 is inserted into the insertion hole 88 through the lower end opening of the insertion hole 88.

  The cover portion 85 extends forward from the mounting portion 84. The cover portion 85 extends forward from the opening peripheral edge portion of the insertion hole 88 in the peripheral wall portion 87. The nozzle cylinder 12 is accommodated in the cover portion 85. The cover portion 85 covers the nozzle cylinder 12 from above, from the front, and from the side.

  As shown in FIG. 2, when the pressing head 5 is located at the lowest position, the upper locking portion 81 and the lower locking portion 83 are locked to each other, so that the holding portion 6 moves upward. To regulate. Thus, the pressing head 5 is held at the lowest position against the upward biasing force from the coil spring 56 (stem 3).

  The urging member 7 urges the operation unit 82. When the front end of the operation unit 82 is pushed up and the operation unit 82 swings around the swing axis L, the operation unit 82 is biased toward the opposite side around the swing axis L by the biasing member 7. . The urging member 7 is provided on the nozzle cylinder 12. The urging member 7 is formed of an elastic piece. The urging member 7 extends upward from the first nozzle cylinder 30 and is disposed between the top wall ring portion 86 and the linking cylinder portion 71.

(Use of dispenser)
Next, the case where the above-described discharger 1 is used will be described. It is assumed that the contents are sucked up from the container main body A into the liquid cylinder 14.

When discharging the contents, as shown in FIG. 2, the head unit 70 is pushed down against the spring force of the coil spring 56 to move the entire pressing head 5 downward. As a result, the linking cylinder portion 71 starts 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 with the linkage cylinder portion 71, the upper valve body 66 is separated downward from the upper valve seat portion 62 of the liquid piston 15.
Accordingly, the liquid cylinder 14 and the first flow passage R1 are in communication with each other through the flow hole 68.

  Further, since the projection piece 72 pushes down the liquid piston 15 by further pressing down the pressing head 5, the liquid piston 15 and the stem 3 can be simultaneously moved downward together with the pressing head 5 and the upper valve body 65. . At this time, the pressing head 5, the upper valve body 65, the liquid piston 15 and the stem 3 are moved downward while the upper valve body 66 is maintained in the state of being spaced downward from the upper valve seat 62 of the liquid piston 15. Can do.

Then, since the liquid piston 15 moves downward in the liquid cylinder 14, the internal volume of the liquid cylinder 14 is gradually reduced and the internal pressure is increased (pressurized). Thereby, the lower valve body 50 closes the communication hole 46. Further, since the liquid piston 15 pushes out the contents in the liquid cylinder 14, the contents pass through the stem 3 (specifically, through the flow hole 68, the first flow path R1, and the second flow path 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 pressing head 5 is pushed down by, for example, a stroke and the stem 3 is lowered to the lowest position, the upper locking portion 81 and the lower locking portion 83 are in sliding contact with each other, and the operation portion 82 is swung. Thus, the lower locking portion 83 is elastically displaced, and the upper locking portion 81 and the lower locking portion 83 are locked with each other. At this time, in the present embodiment, the upper end edge of the lower locking portion 83 slides on the upper guide surface 81a, so that the urging member 7 is pushed backward by the operation portion 82 and elastically deformed while operating the operation portion. 82 swings around the swing axis L, and the lower locking portion 83 is elastically displaced rearward and obliquely downward. When the upper locking portion 81 gets over the lower locking portion 83 in the direction of the axis O, the biasing member 7 is restored and deformed, and the operation portion 82 is biased around the swing axis L, so that the lower locking portion 83 is moved. Is restored and displaced forward and obliquely upward. Thereby, the upper end part of the upper side latching | locking part 81 and the lower end part of the lower side latching | locking part 83 latch in the axis line O direction, and the holding | maintenance part 6 hold | maintains the pressing-down head 5 in the lowest position.

  Here, the holding unit 6 releases the holding of the pressing head 5 by releasing the locking of the upper locking unit 81 and the lower locking unit 83 when the operation unit 82 is operated and swings. In the present embodiment, when the front end portion of the operation portion 82 is pushed up, the lower locking portion 83 is elastically displaced in conjunction with the operation portion 82, thereby causing the upper locking portion 81 and the lower locking portion 83 to move. The lock is released and the holding of the pressing head 5 is released. That is, when the front end portion of the operation portion 82 is pushed up, the operation portion 82 swings around the swing axis L while the biasing member 7 is elastically deformed by the pressing force to the operation portion 82. Thereby, the locking of the upper locking portion 81 and the lower locking portion 83 is released, and the holding of the pressing head 5 by the holding portion 6 is released.

When the holding of the pressing head 5 by the holding unit 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, since the upper valve body 65 and the pressing head 5 are restored and moved upward, they move 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 from the lower side with respect to the upper valve seat portion 62 of the liquid piston 15, and the projecting piece 72 of the linkage cylinder portion 71 is connected to the connection cylinder portion 61 of the liquid piston 15. It is spaced upward from the upper opening end. Particularly, when the upper valve body 66 is seated on the upper valve seat 62, the communication between the liquid cylinder 14 and the first flow passage R1 is blocked.

Further, when the upper valve body 66 is seated on the upper valve seat portion 62, the liquid 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, the discharge piston 13 moves upward in the storage cylinder 10, so that the content stored in the storage cylinder 10 is pushed out of the storage cylinder 10 through the through hole 25. It can be supplied into the cylinder 12. Thereby, the contents can be discharged to the outside through the discharge holes 11.

  Further, since the liquid piston 15 moves upward in the liquid cylinder 14, the pressure in the liquid cylinder 14 is reduced to a negative pressure state, so that the lower valve body 50 opens the communication hole 46. Thereby, the contents in the container main body A can be sucked 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 from the time when the stem 3 and the liquid piston 15 are moved downward to the time when the stem 3 and the liquid piston 15 are restored to the original position, the inside of the container main body A has the second air hole 44 and the second air hole 44 inside. One air hole 23 communicates with the outside. Therefore, the air in the container main body A can be replaced, and even if the contents are sucked into the liquid cylinder 14 from the container main body A, it is possible to prevent the container main body A from being depressurized. Therefore, the smooth restoration movement of the pressing head 5 and the smooth discharge of the contents can be performed.

  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. Then, the contents can be discharged when the stem 3 is restored and moved upward.

  Therefore, the discharged contents can be received not only with one hand but also with both hands. Furthermore, even if one hand is blocked for some reason (for example, when holding a child or holding a baggage), the contents can be discharged with the other hand only ( That is, the pressing head 5 can be pressed down) and the discharged contents can be received. Therefore, it is very easy to use and the convenience can be improved.

  Moreover, when the contents are once stored in the storage cylinder 10 and the pressing head 5 is lowered to the lowest position, the holding head 6 can hold the pressing head 5 at the lowest position. Therefore, when the pressing of 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, after the hand released from the pressing head 5 is brought close to the nozzle cylinder 12, the operation unit 82 is operated, and the pressing head 5 and the stem 3 can be raised to discharge the contents. In addition, for example, after the discharge is finished, the pressing head 5 is lowered for the next discharging, and the pressing head 5 is held at the lowest position by the holding unit 6, so that the next discharging can be smoothly performed. Therefore, convenience can be further improved.

Further, when the pressing head 5 is lowered toward the lowest position, the upper locking portion 81 and the lower locking portion 83 are in sliding contact with each other, and the lower locking portion 83 is accompanied by the swinging of the operation portion 82. Is displaced, and the upper locking portion 81 and the lower locking portion 83 are locked to each other, whereby the holding portion 6 restricts the upward movement of the pressing head 5. Therefore, the pressing head 5 can be held at the lowest lowered position by the holding portion 6 by performing the operation of lowering the pressing head 5 toward the lowest lowered position. Thereby, the convenience can be further improved.
Furthermore, since the operation part 82 covers the nozzle cylinder 12, it can suppress that the discharge device 1 is bulky, and the discharge device 1 can be made compact.

  Further, the nozzle cylinder 12 and the operation portion 82 extend forward from the storage cylinder 10 side, and the front end portion of the operation portion 82 is disposed forward of the swing shaft L. Therefore, immediately after releasing the holding of the pressing head 5 by the holding portion 6 by operating the operating portion 82 so that the operating portion 82 swings by moving the front end portion of the operating portion 82 up and down by hand, the hand is moved to the nozzle. The cylinder 12 can be kept close. Thereby, the convenience can be further improved.

  Further, the front end portion of the operation portion 82 is disposed below the discharge hole 11. Therefore, immediately after the front end portion of the operation unit 82 is operated by hand and the holding of the pressing head 5 by the holding unit 6 is released, the hand can be positioned below the discharge hole 11. Thereby, the convenience can be further improved.

In the present 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 define the amount of contents discharged by one discharge operation by the internal volume of the liquid cylinder 14, and for example, it is easy to discharge a fixed amount of contents.

Moreover, the increased volume that increases with the downward movement of the discharge piston 13 in the internal volume of the storage space S in the storage cylinder 10 decreases with the downward movement of the liquid piston 15 in the internal volume of the liquid cylinder 14. Since the volume is equal to or larger than the volume, when the stem 3 is moved downward, 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.
Therefore, when the stem 3 moves downward, the contents can be reliably stored in the storage cylinder 10, and the contents do not easily flow into the nozzle cylinder 12 from the storage cylinder 10. 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 a 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, it is easy to receive the discharged contents, and usability can be improved.

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

  For example, in the above-described embodiment, the pump mechanism including the liquid cylinder and the liquid piston is employed as the discharge mechanism. However, the present invention is not limited to this case. For example, an aerosol mechanism may be employed in which the container body is filled with the content 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, the same effect as the present embodiment can be achieved.

  In the above 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 is connected to the liquid cylinder 14 and the container body. By blocking 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 open / close valve is provided in the nozzle cylinder 12, the open / close valve shuts off the communication between the storage cylinder 10 and the discharge hole 11 when the storage cylinder 10 is depressurized, and the lower valve body is the storage cylinder 10 when the storage cylinder 10 is pressurized. And a configuration in which the discharge hole 11 communicates with each other. In this case, when the discharge piston 13 together with the stem 3 moves downward in the storage cylinder 10, the open / close valve blocks communication between the storage cylinder 10 and the discharge hole 11, and the pressure in the storage cylinder 10 is reduced. Thereby, the contents in the liquid cylinder 14 can be supplied to the storage cylinder 10.

  In the above embodiment, when the pressing head 5 is lowered to the lowest position, the lower locking portion 83 is elastically displaced, and the upper locking portion 81 and the lower locking portion 83 are locked to each other. However, the present invention is not limited to this. For example, when the upper locking portion 81 and the lower locking portion 83 are locked to each other, the lower locking portion 83 does not necessarily have to be elastically displaced and is displaced without receiving an elastic restoring force. Also good.

  In the said embodiment, although the discharge device 1 discharges the content with a liquid state, this invention is not limited to this. For example, the present invention can also be applied to a discharger that discharges the contents in the form of bubbles. For example, a discharge cylinder is arranged in a liquid cylinder that communicates with the stem, and moves up and down in conjunction with the stem and is slidable in the liquid cylinder. A liquid piston for supplying the contents in the stem, and an air cylinder in which an air piston linked to the stem is slidably accommodated in the vertical direction. With the gas-liquid mixing chamber for mixing the supplied content and the air supplied from the air cylinder, and the gas-liquid mixture mixed in the gas-liquid mixing chamber foamed to make the content foamy, 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 said embodiment, although the discharge hole 11 is formed in the front-end part of the nozzle cylinder 12, this invention is not limited to this. For example, the discharge hole 11 may be formed in an intermediate portion in the front-rear direction of the nozzle cylinder 12.

The front end portion of the operation portion 82 may not be disposed below the discharge hole 11.
The front end portion of the operation portion 82 may not be disposed in front of the swing shaft L and the storage cylinder 10.
The lower locking portion 83 may not be disposed behind the swing axis L. Further, the lower locking portion 83 may not be disposed above the swing axis L.

  In addition, it is possible to appropriately replace the constituent elements in the embodiment with known constituent elements without departing from the spirit of the present invention, and the above-described modified examples may be appropriately combined.
