Thereby, discharge of the contents when not in use is prevented in advance.

JP 2006-327612 A

However, since the stopper is a detachable part, there is a high possibility that it will be lost. If it is lost, the operation of pushing down the head cannot be disabled, so that the contents may be accidentally discharged when not in use.
Moreover, since it is necessary to remove a stopper at the time of use, you have to store the removed stopper temporarily. Therefore, it takes time and effort to store the stopper, which makes it troublesome.

  The present invention has been made in consideration of such circumstances, and its purpose is to avoid the danger of loss or temporary storage, and to easily prevent discharge of contents by a one-touch operation when necessary. It is to provide a dispenser that can be realized.

In order to achieve the above object, the present invention provides the following means.
A discharger according to the present invention is attached to a mouth portion of a container filled with contents, and has a mounting cap having a protruding cylinder protruding upward, and penetrates through the mounting cap in an upwardly biased state. A discharger comprising: a pump part having a stem provided; and a pressing head having a discharge opening for discharging the contents transferred by the pump part to the outside and fixed to the upper end of the stem. The protruding cylinder has a diameter between a lock position that contacts the lower end of the pressing head and restricts downward movement and a release position that avoids contact with the lower end of the pressing head and allows downward movement. The movable part which can be reciprocated along a direction is provided.

In the ejector according to the present invention, the downward movement of the pressing head can be restricted or allowed by setting the movable part provided in the protruding cylinder to the lock position or the release position. More specifically, when discharging the contents, first, the movable portion is moved to a release position where contact with the lower end of the pressing head is avoided. Thereby, while pressing down a pressing head and moving it downward, the stem of a pump part can be moved downward with this. As a result, the contents transferred by the pump unit can be discharged to the outside through the discharge opening of the pressing head.
On the other hand, when the dispenser is not used, the movable portion is moved from the release position along the radial direction and set at the lock position. Thereby, even if it is going to push down a pressing head, since a movable part contacts the lower end of a pressing head and a downward movement is controlled, a pressing head cannot be moved below. Accordingly, it is possible to prevent the contents from being accidentally discharged.

  In this way, the downward movement of the pressing head can be controlled by a simple operation of simply setting the movable part at the lock position or the release position, and the discharge control of the contents can be performed. In particular, when not in use, it is very easy to use because the discharge of contents can be easily prevented by a one-touch operation by simply setting the movable part at the lock position. In addition, since the movable part is provided on the protruding cylinder of the mounting cap (is integrally formed), unlike the conventional one formed as a separate member, there is a risk of loss or troublesome storage. There is no. Therefore, also in this point, it is easy to use and excellent in convenience.

  A discharger according to the present invention is the discharger according to the present invention, wherein the protruding cylinder includes a fixed wall partially cut in a circumferential direction, and the movable portion is disposed at a divided portion of the fixed wall. A movable wall that is movable in the radial direction, and the movable wall and the fixed wall are connected to each other, and reversely deformed in the radial direction along with the movement of the movable wall, thereby moving the movable wall between the lock position and the release position. And an inversion deformable wall to be held by either of them.

In the discharger according to the present invention, the movable portion is configured by a movable wall that is movable in the radial direction and a reverse deformation wall that connects the movable wall and the fixed wall, and the movable wall is locked or released. The downward movement of the pressing head can be restricted or allowed by moving to the position. In particular, the reverse deformation wall that connects the movable wall and the fixed wall is reversely deformed in the radial direction as the movable wall moves, so that the movable wall is held at either the lock position or the release position. Is possible. That is, when the movable wall is set at the lock position or the release position, the movable wall can be left as it is until the next movement.
Therefore, it is possible to prevent the downward movement of the pressing head from being unexpectedly restricted during use, or the downward movement of the pressing head from being unexpectedly permitted when not in use. Therefore, it is possible to obtain a dispenser with higher operational reliability.

  In the discharge device according to the present invention, in the discharge device according to the present invention, the movable wall is provided with a knob for moving the movable wall in a radial direction, and the pressing head includes the knob and the knob when moved downward. A slit for preventing the interference is formed.

In the dispenser according to the present invention, since the movable wall can be moved in the radial direction using the knob and set at the lock position or the release position, the operability can be improved and it is easier to use. Moreover, since the slit which prevents interference with a knob | pick part is formed in the pressing head, a knob | pick part can be penetrated in a slit at the time of a downward movement. Therefore, the contents can be discharged without being affected by the knob.
In particular, since the knob portion enters the slit, it is possible to prevent the pressing head from rotating in the circumferential direction during the pressing operation. Accordingly, the contents can be discharged in a state where the direction of the discharge opening is stabilized.

  The ejector according to the present invention is characterized in that, in the ejector according to the present invention, the knob portion constantly enters the slit and restricts rotation of the pressing head in the circumferential direction.

  In the ejector according to the present invention, the knob is always in the slit regardless of the pressing operation of the pressing head, and the rotation of the pressing head in the circumferential direction is restricted. Accordingly, it is possible to prevent the pressing head from rotating even before the pressing. Therefore, it is possible to suppress the occurrence of looseness, rattling, or the like when the pressing head is attached.

  The ejector according to the present invention is characterized in that, in the ejector according to the present invention, the pressing head is disposed so as to cover a radially outer side of the protruding cylinder.

  In the ejector according to the present invention, the pressing head is disposed so as to cover the radially outer side of the protruding cylinder, so that moisture, dust and the like hardly enter the inside through the gap between the pressing head and the protruding cylinder. Therefore, the quality of the discharger can be improved.

  According to the dispenser of the present invention, there is no risk of loss or temporary storage, and discharge of contents can be easily prevented by performing a one-touch operation on the movable part when necessary. Therefore, it is possible to obtain a dispenser that is very easy to use and excellent in convenience.

Hereinafter, embodiments of a dispenser according to the present invention will be described with reference to FIGS. 1 to 6.
As shown in FIGS. 1 and 2, the discharge device 1 of the present embodiment includes a bottomed cylindrical mounting cap 3 that is mounted on the mouth portion 2 a of the container 2 filled with the contents, and the mounting cap 3. The pump part 4 which has the stem 20 penetrated so that a downward movement was possible in the upward biased state, and the pressing head 5 fixed to the upper end of the stem 20 are provided.

  Here, the central axes of the container 2, the mounting cap 3, and the stem 20 are located on a common axis. In the present embodiment, this common axis is referred to as the central axis O, the pressing head 5 side along the central axis O direction is referred to as the upper side, the bottom side (not shown) of the container 2 is referred to as the lower side, and the direction orthogonal to the central axis O. Is referred to as the radial direction, and the direction of circling around the central axis O is referred to as the circumferential direction.

The mounting cap 3 includes a top wall portion 10 having a circular opening at the center, a peripheral wall portion 11 extending downward from an outer peripheral edge portion of the top wall portion 10, and an inner portion of the top wall portion 10. The projecting cylinder 12 extends integrally from the peripheral edge so as to project upward.
A female threaded portion is formed on the inner peripheral surface of the peripheral wall portion 11, and the mounting cap 3 is mounted on the container 2 by screwing the female threaded portion into a male threaded portion formed in the mouth portion 2 a.

As shown in FIGS. 3 and 4, the protruding cylinder 12 includes a substantially C-shaped fixed wall 15 partially cut in the circumferential direction and a movable portion 16 that can reciprocate along the radial direction. ing. The movable portion 16 has two points: a lock position P1 that contacts the lower end of the pressing head 5 to restrict downward movement, and a release position P2 that avoids contact with the lower end of the pressing head 5 and allows downward movement. It can be moved back and forth between them.
More specifically, the movable portion 16 is disposed at a divided portion of the fixed wall 15 and is movable in the radial direction, and connects the movable wall 16a and the fixed wall 15 to each other. The reversal deformation wall 16b is configured to be reversibly deformed in the radial direction along with the movement of the movable wall 16a to hold the movable wall 16a at either the lock position P1 or the release position P2.

  That is, the downward movement of the pressing head 5 is restricted or allowed by moving the movable wall 16a to the lock position P1 or the release position P2. The lock position P1 of the present embodiment is a position where the movable wall 16a is pulled out radially outward, and a part of the movable wall 16a and the reverse deformation wall 16b is a position of an outer cylinder 32 which will be described later of the pressing head 5. It is supposed to be the position that comes directly below. On the other hand, the release position P2 is a position moved radially inward from the lock position P1 (the movable wall 16a is pushed radially inward).

  The reverse deformation wall 16b is reversely deformed with the connecting portion with the fixed wall 15 as a base point, and maintains the deformed state as long as the movable wall 16a does not move. Therefore, as described above, the movable wall 16a can be held at either the lock position P1 or the release position P2.

  The movable wall 16a is integrally provided with a knob 17 for moving the movable wall 16a in the radial direction and setting the movable wall 16a at either the lock position P1 or the release position P2. The knob portion 17 extends in the vertical direction, and protrudes radially outward from the movable wall 16a. The claw portion is connected to the outer end of the plate 17a and extends in the circumferential direction. 17b. Since the movable wall 16a can be moved in the radial direction using this knob 17, the design is very easy to operate and excellent in usability.

As shown in FIGS. 1 and 2, the pump unit 4 is provided with a stem 20, a cylinder 21 in which a lower portion of the stem 20 is arranged to be movable up and down, and a slidable up and down inside the cylinder 21. A piston member (not shown) and a biasing member (not shown) that biases the stem 20 and the piston member upward.
The upper portion of the stem 20 is located above the upper end of the cylinder 21 and is disposed in the protruding cylinder 12 of the mounting cap 3, and the upper end portion thereof is positioned above the upper end of the protruding cylinder 12. . The cylinder 21 is formed in a cylindrical shape and is disposed coaxially with the central axis O. At the upper end of the cylinder 21, a flange portion 21 a protrudes outward in the radial direction over the entire circumference, and this flange portion 21 a is formed between the lower surface of the top wall portion 10 of the mounting cap 3 and the mouth portion 2 a. It is sandwiched and fixed in the vertical direction via the packing 22 by the opening edge. The upper end of the pipe 23 is fitted into the lower end of the cylinder 21, and the lower end opening of the pipe 23 is located at the bottom of the container 2.

The pressing head 5 is extended downward from the top wall 30, the inner cylinder 31 extending downward from the center of the lower surface of the top wall 30, and the outer peripheral edge of the top wall 30, An outer cylinder 32 that surrounds the inner cylinder 31 from the outer side in the radial direction, and a nozzle portion 33 that protrudes from the outer peripheral surface of the outer cylinder 32 toward the outer side in the radial direction and communicates with the inside of the inner cylinder 31. Yes.
The upper end portion of the stem 20 of the pump portion 4 is fitted into the inner cylinder 31 so as to communicate with each other. Therefore, the inside of the stem 20 and the inside of the nozzle portion 33 communicate with each other via the inner cylinder 31. Thereby, the contents transferred by the pump unit 4 can be discharged to the outside from the discharge opening 33 a formed at the tip of the nozzle unit 33.

The outer cylinder 32 is disposed so as to cover the radially outer side of the protruding cylinder 12. Further, the outer cylinder 32 is formed with a slit 34 for receiving the plate 17a of the knob 17 and preventing interference with the knob 17 when moving downward. In the present embodiment, not only during downward movement, the plate 17a always enters the slit 34, and the rotation of the pressing head 5 in the circumferential direction is restricted. Therefore, the position of the nozzle part 33 is designed to always face in the same direction.
In this embodiment, a case where a gap is provided between the outer peripheral surface of the protruding cylinder 12 and the inner peripheral surface of the outer cylinder 32 is taken as an example, but the outer peripheral surface of the protruding cylinder 12 and the outer cylinder are exemplified. It is also possible to configure so that the inner peripheral surface of 32 is in sliding contact.

next. The case where the contents are discharged using the discharge device 1 configured as described above will be described.
First, as shown in FIG. 5, it is confirmed that the movable wall 16a is set at the release position P2, and the pressing head 5 is in a state in which it can move downward. If the movable wall 16a is set at the lock position P1 as shown in FIG. 1, the knob 17 is pushed in to move the movable wall 16a radially inward as shown in FIG. Set to P2. At this time, since the movable wall 16a can be moved using the knob 17, the operation is easy. Moreover, since the movable wall 16a can be pushed in while pressing the fingertip against the claw portion 17b, the operability is very good.
By the way, the reverse deformation wall 16b is reversely deformed in the radial direction as the movable wall 16a moves, and the movable wall 16a is held at the release position P2. Therefore, the movable wall 16a can be kept set at the release position P2 until the movable wall 16a is moved again. Therefore, it is possible to prevent the downward movement of the pressing head 5 from being unexpectedly restricted.

  Next, after confirming that the movable wall 16a is set at the release position P2 as shown in FIG. 5, the pressing head 5 is pushed down and moved downward as shown in FIG. Then, with this movement, the stem 20 is moved downward. In conjunction with the movement of the stem 20, the piston member moves downward while being in sliding contact with the inner peripheral surface of the cylinder 21. As a result, the contents in the cylinder 21 are compressed, and the compressed contents in the cylinder 21 enter the stem 20 and move upward in the stem 20, and then flow into the nozzle portion 33. . As a result, the contents can be discharged from the discharge opening 33 a of the nozzle portion 33.

By the way, since the plate 17a of the knob 17 enters the slit 34 formed in the outer cylinder 32 of the pressing head 5 while the pressing head 5 is moved downward, the contents are not affected by the knob 17 at all. An object can be discharged reliably. In particular, since the plate 17a of the knob 17 enters the slit 34, the pressing head 5 can be prevented from rotating in the circumferential direction during the pressing operation. Therefore, the contents can be discharged in a state where the direction of the nozzle portion 33, that is, the direction of the discharge opening 33a is stabilized.
Moreover, as shown in FIGS. 1 and 2, the plate 17 a of the knob portion 17 of this embodiment has entered the slit 34 before the pressing head 5 is pressed down, and the pressing head 5 rotates in the circumferential direction. Is regulated. That is, the pressing head 5 is prevented from rotating. Therefore, a stable ejection operation can be performed without the pressing head 5 rotating during use.

  When the outer cylinder 32 of the pressing head 5 is slidably contacted with the fixed wall 15 of the protruding cylinder 12 (sliding contact), the pressing head 5 may be rattled or shaken when pressed down. It can suppress more reliably that it generate | occur | produces.

  When the pressing head 5 is released from being pressed after the contents are discharged, the piston member moves together with the stem 20 in sliding contact with the inner peripheral surface of the cylinder 21 by the upward biasing force of the biasing member. Thereby, the inside of the cylinder 21 is depressurized, and the contents stored in the container 2 are sucked into the cylinder 21 through the pipe 23. Thereby, it can prepare for the next discharge.

On the other hand, when the dispenser 1 is not used, the knob 17 is pulled out to move the movable wall 16a radially outward, and is set at the lock position P1 as shown in FIG. At this time, since the movable wall 16a can be pulled out while hooking the fingertip on the claw portion 17b, the operability is very excellent as in the case of setting at the release position P2.
Further, the reverse deformation wall 16b is reversely deformed radially outward with the movement of the movable wall 16a, and the movable wall 16a is held at the lock position P1. Therefore, until the movable wall 16a is moved again, the movable wall 16a can be kept in the locked position P1. Therefore, it is possible to prevent the downward movement of the pressing head 5 from being allowed unexpectedly.

  As described above, by setting the movable wall 16a at the lock position P1, even if the pressing head 5 is to be pushed down, a part of the movable wall 16a and the reverse deformation wall 16b contact the lower end of the outer cylinder 32 of the pressing head 5. Since the downward movement is restricted, the pressing head 5 cannot be moved downward. Accordingly, it is possible to prevent the contents from being accidentally discharged.

As described above, according to the dispenser 1 of the present embodiment, the downward movement of the pressing head 5 can be controlled by a simple operation by simply setting the movable wall 16a at the lock position P1 or the release position P2, and the contents can be discharged. Control can be performed.
In particular, when not in use, the discharge of the contents can be easily prevented by a one-touch operation by simply setting the movable portion 16 at the lock position P1, so that it is very easy to use. Further, since the movable portion 16 including the movable wall 16a and the reverse deformation wall 16b is provided on the protruding cylinder 12 of the mounting cap 3, unlike the conventional one, there is a risk of loss and temporary storage. There is not. Therefore, also in this respect, it is very easy to use and excellent in convenience.

Further, as described above, the reverse deformation wall 16b holds the movable wall 16a at the lock position P1 or the release position P2, so that the downward movement of the pressing head 5 is unexpectedly restricted during use, or is unexpectedly pressed when not in use. It is possible to prevent the downward movement of the head 5 from being allowed. Therefore, the discharger 1 with high operation reliability can be obtained.
Further, since the pressing head 5 is disposed so as to cover the radially outer side of the protruding cylinder 12, it is difficult for moisture, dust, or the like to enter the inside through the gap between the outer cylinder 32 of the pressing head 5 and the protruding cylinder 12. Designed to structure. Therefore, a high-quality discharger 1 can be obtained.

  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 unit 4 that discharges the contents in liquid form has been described as an example, but an air cylinder and an air piston may be added to the configuration, and a former pump that discharges the contents in a foam shape may be used. Or it is good also as a spray pump which discharges the contents in the shape of a mist.

  In the above embodiment, the movable wall 16a is set to the release position P2 by pushing it inward in the radial direction, and is set to the lock position P1 by pulling it outward in the radial direction. Conversely, the movable wall 16a may be set to the lock position P1 by pushing it inward in the radial direction, and set to the release position P2 by pulling it outward in the radial direction.

Further, in the above embodiment, the case where the movable portion 16 is configured by the movable wall 16a and the reverse deformation wall 16b has been described as an example. However, there is no movable wall, and a knob is provided at the center of the arc-shaped reverse deformation wall. It may be a configuration in which is protruded. Even in this case, the same effects can be achieved. In any case, it is sufficient that the movable portion is configured to be able to reciprocate between the lock position P1 and the release position P2 along the radial direction.
Further, in the above embodiment, when the movable part 16 is set at the lock position P1, at least a part of the movable part 16 (at least one of the movable wall 16a or the reverse deformation wall 16b) comes into contact with the lower end of the pressing head 5. It is sufficient if it is configured. Further, the downward movement of the pressing head 5 may be restricted by bringing the knob 17 (claw portion 17b) into contact with the lower end of the pressing head 5 when the locking position P1 is set.
