Description

  The present invention relates to a discharger for discharging a liquid contained in a container by a pump and a container with a discharger.

Many discharge devices having a structure for discharging the liquid contained in the container from the discharge hole of the pressing head by the action of a pump have been proposed in Japanese Patent Application Laid-Open No. 2009-131807. Further, a structure that prevents the pressing head from being pushed down in the unused state and prevents the liquid from being ejected from the pressing head in the unused state has been proposed. For example, Japanese Patent Laid-Open No. 2001-180774 has been proposed. No. Gazette). In this conventional example, in the unused state, special considerations are given to prevent the liquid from being returned to the unused state after taking out the liquid in the container by removing the cap (stopper) or pulling out the pressing head. Not.
The stopper for a container with a pump disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2001-180774) is a liquid content that is airtightly attached to a container body and a mouthpiece of the container body, and is contained in the container body. In a container with a pump comprising a cap part having a pump mechanism for discharging an object and a pump part attached to the upper end of the cap part, the pump mechanism is prohibited from being detachably fitted to the cap. After the stopper is removed in the unused state, the pump part is pushed down to discharge the liquid, and then this stopper can be attached again, so that the liquid in the container may be pulled out in the unused state. There is a problem that there is.

1. The dispenser of the present invention can enhance the function of preventing unauthorized use. A cosmetic solution or the like equipped with this dispenser can be safely and reliably delivered to the user.
2. Since the stopper attached to the lower part of the pressing head in the unused state is covered with the cover part of the outer cap, the stopper cannot be released unless the cover of the outer cap is removed. And the structure which cannot remove an outer cap from an inner cap was implement | achieved by fitting an outer cap and an inner cap.
3. In a state where the discharge device is mounted on the container, the entire discharge device cannot be removed because the structure cannot be detached from the container. Therefore, the maintenance function of an unused state can be improved, and mixing of foreign substances can be prevented even after opening.
4). A stopper, which is detachably mounted between the pressing head and the top wall of the inner cap, is covered with a cover portion of the outer cap, and the outer cap main body is externally fitted to the inner cap. A removal prevention means is provided between the inner cap and the outer cap, which is held by the engagement of the cap with the inner cap and prevents the inner cap from being removed from the neck of the container. For this reason, the outer cap cannot be removed from the inner cap by fitting the inner cap and the outer cap, and at least the cover portion of the outer cap is removed, so that the stopper can be removed, and the stopper is pressed. If it is not removed from between the top wall and the top wall of the inner cap, the pressing head is pushed down, and the liquid contained in the container cannot be discharged from the discharge hole. In particular, if the stopper is made removable by removing the cover of the outer cap, etc., it is impossible to return to the state before removing the cover of the outer cap. The removal of the stopper and the removal of the outer cap in the state can be reliably prevented, the liquid can be reliably prevented from being extracted from the container in the unused state, and the unused state can be reliably held.
5. When screwing the inner cap onto the neck of the container, the inner cap is covered with the outer cap, so torque cannot be transmitted directly to the inner cap, and the torque applied to the outer cap is applied to the inner cap through the ratchet mechanism. Will be affected. When the outer cap is rotated in the direction in which the inner cap is screwed onto the neck of the container, the inner cap and the outer cap are engaged by the ratchet mechanism, and the inner cap rotates together with the outer cap. Although it is possible to more securely attach the inner cap to the neck, when the outer cap is rotated in a direction to release the screwing of the inner cap to the neck of the container, the inner cap and the outer cap are in a ratchet mechanism. And the outer cap is idled. Therefore, unless the outer cap is removed from the inner cap, the inner cap cannot be removed from the neck of the container, so that the unused state can be more reliably maintained.
6). By pulling the cover portion of the outer cap away from the main body portion of the outer cap, the cover portion of the outer cap is cut along the fragile portion, so that the stopper can be removed. Therefore, by removing this stopper, the pressing nozzle can be pushed down, and the liquid contained in the container can be discharged. As a result, after the outer cap is cut along the fragile portion in the unused state, it becomes impossible to return to the state before the outer cap is cut off. It is possible to reliably prevent the return to the unused state after setting.
7). A locking mechanism is provided between the neck of the container and the inner cap, and the engagement torque of the ratchet mechanism when the inner cap is rotated in the direction of attaching the inner cap to the container neck attaches the inner cap to the neck of the container. The engagement torque of the ratchet mechanism is larger than the engagement torque of the locking mechanism at the time of rotation and is rotated in the direction of removing the inner cap from the neck of the container. When the outer cap is rotated in the direction in which the inner cap is screwed onto the neck of the container, the inner cap and the outer cap are engaged with each other by the ratchet mechanism. The inner cap can be rotated together with the outer cap, and the neck of the container and the inner cap can be engaged with each other by a lock mechanism. Compared with the case of mounting without locking mechanism, the inner cap hardly removed from the neck of the container. Therefore, in addition to preventing the inner cap from being removed by the ratchet mechanism, the neck 22 of the container is provided by a torque balance between the engagement torque in the attachment direction by the ratchet mechanism, the engagement torque in the removal direction, and the engagement torque and the release torque by the lock mechanism. It is possible to prevent the inner cap from being removed more reliably.
8). The stopper is located below the retaining rib provided on the top side of the inner cylinder of the inner cap and is covered by the cover of the outer cap, so that the stopper is prevented from being pulled out even if the pressing head is pulled out. it can. Therefore, even when the pressing head is removed from the top end of the pump stem, the stopper head cannot be pulled out because the retaining rib is obstructed unless the cover of the outer cap is removed. In this case, it is possible to reliably prevent the pressing head from being attached again and enabling the pressing head to be pushed down, and to hold the unused state more reliably.
9. Each of the outer peripheral surface of the protruding sheath cylinder part covering at least a part of the stem protruding upward from the communication hole and the inner peripheral surface of the insertion recess of the pressing head into which the protruding sheath cylinder part is inserted is a polygon in the radial direction. By forming it in a shape, it is possible to position the direction of the pressing head. For this reason, by positioning the direction of the pressing head, the container can have directionality, and the assembly process of the outer cap becomes easy. Moreover, since the direction of the nozzle of the pressing head can be changed by the elastic deformation of the resin of the member and can be fixed at that position, the position of the remaining liquid and the suction tube can be specified. As a result, the inner solution can be used up. In addition, since the front and back surfaces can be determined, it is possible to specify the position where a label or the like is attached, and it is possible to easily align all the pressing heads in one direction when a plurality of containers are displayed.
10. At least a part of the stem protruding upward from the communication hole is covered with a protruding sheath tube portion 39, a retaining rib is provided on the protruding sheath tube portion, and a stopper is attached. For this reason, when the pressing head is removed and the liquid contained in the container is pulled out from the upper end of the stem and then the pressing head is reattached to the upper end of the stem, the upper end of the stem is the protruding sheath of the inner cap. Since it becomes impossible to attach the pressing nozzle to the upper end of this stem again and to return to the unused state, it is possible to hold the unused state more securely, and to remove the pressing nozzle from the container. The return to the unused state after removing the liquid can be prevented more reliably.
11. A container equipped with a discharger can be kept unused before opening, and it is difficult to mix foreign matter after opening, and the remaining amount can be reduced.

The present invention is attached to the neck of a container containing a liquid, and has a ceiling wall portion provided with a communication hole communicating with the mouth portion of the container, and covers the periphery of the ceiling wall portion and is screwed onto the neck portion of the container. An inner cap having a cylindrical peripheral wall portion to be joined, and at least a part of a stem inserted through the communication hole of the inner cap and attached so as to be movable downward while being urged from above communicate with each other A discharge device including a pump protruding above a hole and a pressing head provided at an upper end of a stem of the pump and having a nozzle portion in which a discharge hole is formed, and prevents the pressing head from being pushed down. A stopper is interposed between the pressing head and the top wall of the inner cap and is detachably attached. A cover that covers the stopper, a cylindrical main body that is externally fitted to the inner cap, Body cap on the inner cap When allowed outside fitted and an outer cap having an engaging portion to be engaged with the inner cap. The cover portion of the outer cap is provided with a notch for avoiding contact of the nozzle portion of the pressing head to the cover portion when the outer cap is attached from the pressing head side, and between the inner cap and the outer cap. A removal preventing means for preventing the removal of the inner cap from the neck of the container is provided. By fitting the outer cap and the inner cap, the outer cap cannot be removed from the inner cap, and at least the cover part of the outer cap is removed, so that the stopper can be removed. Unless it is removed from the space between the top wall of the inner cap, the pressing head is pushed down, and the liquid contained in the container cannot be discharged. In particular, when the stopper is made removable by removing the cover portion of the outer cap, it is not possible to return to the unused state before removing the cover portion of the outer cap.
When the dispenser of the present invention is relatively rotated in the direction in which the inner cap is screwed into the neck of the container, the inner cap and the outer cap are engaged, and the inner cap rotates together with the outer cap. While the inner cap can be more securely attached to the neck of the container, in the case of relative rotation in the direction to release the screwing of the inner cap to the neck of the container, the inner cap and the outer cap Does not engage, and the outer cap rotates idle. Therefore, this inner cap cannot be removed from the neck of the container unless the outer cap is removed from the inner cap. The cover part of the outer cap can be removed from the inner cap by pulling the locking part of the outer cap away from the main body part of the outer cap and separating the outer cap along the fragile part. Become. In this state, by removing the stopper, it becomes a state where the pressing nozzle can be pushed down and the liquid stored in the container can be discharged, so after separating the outer cap along the fragile portion in the unused state, The outer cap cannot be returned to the state before being cut off.

In the dispenser of the present invention, a locking mechanism that is engaged when the inner cap is attached to the neck of the container is provided between the neck of the container and the inner cap, and the inner cap is attached to the neck of the container. The engagement torque of the ratchet mechanism when rotated in the direction is set larger than the engagement torque of the lock mechanism, and smaller than the release torque when the inner cap is removed from the neck of the container against this lock mechanism. Yes. When the outer cap is rotated in the direction in which the inner cap is screwed onto the neck of the container, the inner cap can be rotated together with the outer cap by engaging the inner cap with the outer cap by the ratchet mechanism. The neck and the inner cap can be engaged with each other by a lock mechanism. Compared to the case where the inner cap is engaged with the neck of the container, it is difficult to remove the inner cap from the neck of the container. Therefore, in addition to preventing the inner cap from being removed by the ratchet mechanism, This torque balance prevents the inner cap from being removed from the container neck more reliably.
The pressing head of the discharger of the present invention is formed with a recess for accommodating the tip end side of the protruding sheath cylinder of the inner cap. By providing a resistance means for preventing free rotation in the relationship between the two caused by the storage, the positional relationship between the two can be defined, and the direction of the nozzle can be specified. As a means for this, it is possible to provide a mechanism that causes interference resistance when the pressing head is rotated, such as a combination of polygons of hexagons or more, and vertical ribs formed on both sides. This interference resistance is set to a level that can be overcome by applying a strong force by a general person, and to ensure convenience during use.
A description will be given by taking a polygon as an example. In the discharge device of the present invention, each of the outer peripheral surface of the protruding sheath cylindrical portion that covers at least a part of the stem that protrudes upward from the communication hole and the inner peripheral surface of the insertion recess into which the protruding sheath cylindrical portion is inserted is a diameter. The cross section is formed in a polygonal shape. Since the direction of the pressing head can be positioned, the liquid contained in the container can be discharged without leaving the container more reliably, and the container can have directionality. When the container is displayed or the like, all the pressing heads can be easily aligned in one direction. Here, the outer peripheral surface of the protruding sheath tube portion and the inner peripheral surface of the insertion recess are preferably polygons having a radial cross section of hexagon or more so that the pressing head can rotate in the circumferential direction when a predetermined force is applied. The octagonal cross section in the radial direction is more preferable. Even when the pressing head is removed from the upper end of the pump stem, the stopper cannot be removed by the cover part of the outer cap, and the stopper cannot be pulled upward by the retaining rib. After the stopper is removed, the pressing head is attached again and the pressing head cannot be pushed down.
In the discharge device of the present invention, a retaining rib is provided on a cylindrical projecting sheath tubular portion covering at least a part of the stem projecting upward from the communication hole, and a stopper is attached to the projecting sheath tubular portion. After removing the liquid from the upper end of the stem and pulling out the liquid contained in the container, etc., when trying to reattach the pressing head to the upper end of the stem, the upper end of this stem enters the protruding sheath cylinder of the inner cap, The pressing nozzle cannot be attached to the upper end of the stem again, and cannot be returned to the unused state. A stopper is attached to the protruding sheath cylinder of the inner cap, but if the protruding sheath cylinder is not formed and the pump stem is exposed and not covered, the stopper is attached to the stem. It can also be set as the structure attached.

1. Container The size of the container can be appropriately determined depending on the use and dose of the liquid to be stored. In this container, for example, liquid such as cosmetics is stored, and a mouth portion for storing and taking out liquid in the container is provided at the upper end. The container is preferably partially or entirely transparent so that the remaining amount can be seen. The contained liquid is sucked out from a tube attached to the lower end of the pump.

2. Inner cap The inner cap is provided with a female screw that is screwed into the neck of the container, and a communication hole for mounting the pump is provided at the center. Moreover, the inner cap can form a sheath-like cylinder that extends upward and covers the stem.
The inner cap is attached to the neck of the container, and a communication hole communicating with the mouth of the container is provided in the top wall. A cylindrical peripheral wall portion that is screwed onto the neck portion of the container is provided. Further, a cylindrical projecting sheath tube portion is provided at a portion between the top wall portion of the inner cap and the pressing head. A retaining rib for preventing the stopper from coming off upward in a state where the pressing head is removed from the stem of the pump can be provided on the outer peripheral surface of the protruding sheath tube portion. The outer peripheral surface of the protruding sheath tube portion can be formed in a polygonal cross section. A locking mechanism that engages when the inner cap is attached to the neck of the container may be provided between the inner cap and the neck of the container. This locking mechanism is set so that the engagement torque when attaching the inner cap to the neck of the container is smaller than the release torque when removing the inner cap from the neck of the container against this locking mechanism. Is preferred.

3. The pump is inserted and attached to the communication hole of the inner cap, and a part of the stem inserted so as to be movable downward by urging from above is protruded upward from the communication hole. Note that at least a part of the stem that protrudes upward from the communication hole is covered with a protruding sheath tube portion of the inner cap. A pressing head is attached to the upper end of the stem.

4). Pressing Head The pressing head has a nozzle part in which a discharge hole is formed, and is attached in close contact with the upper end of the stem of the pump. When contacting the protruding sheath cylinder of the inner cap, a fitting recess is formed in which the protruding sheath cylinder of the inner cap is fitted when the pressing head is pushed down.

5. Stopper The stopper is used to prevent the pressing head from being pushed down and to keep the unused state. The stopper is detachably mounted between the pressing head and the top wall of the inner cap in the unused state. The stopper has a cylindrical shape in which a cutout is formed in the vertical direction covering the protruding sheath cylinder portion of the stem or the inner cap, and can be attached and detached by passing the cutout portion. When the projecting sheath tube portion is formed on the inner cap, it is detachably attached to the outer peripheral surface of the projecting sheath tube portion. When the protruding sheath tube portion is polygonal, the stopper cross-section inner peripheral surface is formed in a polygonal cross-section. The rotation of the stopper is restricted by the polygon. In use, the stopper is removed.

6). Outer cap The outer cap is engaged with the inner cap when the cover portion that covers the stopper, the cylindrical main body portion that is externally fitted to the inner cap, and the main body portion is externally fitted to the inner cap. And an engaging portion. The cover portion is provided with a notch portion for avoiding contact of the nozzle portion of the pressing head with the cover portion when the outer cap is attached from the pressing head side. A removal preventing means is provided between the outer cap and the inner cap to prevent the inner cap from being removed from the neck of the container. This removal prevention means is preferably a ratchet mechanism, and in the case of rotation in a direction in which the inner cap is screwed into the neck of the container, the inner cap and the outer cap are engaged to engage the inner cap with the outer cap. Enable rotation operation. On the other hand, after the attachment to the neck of the container, in the case of relative rotation in the direction in which the inner cap is unscrewed, the ratchet mechanism is disengaged and the outer cap is idled. . The engagement torque of the ratchet mechanism is set larger than the engagement torque of the lock mechanism when the inner cap is attached to the neck of the container. When the inner cap is removed from the neck of the container against this locking mechanism, the ratchet is not aligned and no unlocking torque is applied to the lock.
The cover part is separated from the main body part during use so that the stopper can be accessed. A fragile portion is formed between the cover portion and the main body portion in the circumferential direction and can be separated from the fragile portion.
A bent piece is provided on the side of the cutout portion provided in the cover portion, and can be formed as a finger hook portion or a knob when the cover portion is separated.

7). Assembling method Attach the pressing head to the upper end of the stem of the pump installed in the communication hole of the inner cap. Thereafter, a stopper is attached between the pressing head and the top wall of the inner cap so that the pressing head cannot be pushed down. When the protruding sheath tube portion is formed on the inner cap, a stopper is attached to the outer surface of the protruding sheath tube portion. At this time, the push-down head accommodates a retaining rib provided on the protruding sheath tube portion of the inner cap in the fitting recess, making it difficult for the stopper to be pulled upward.
Next, the outer cap is crowned on the inner cap. The notch provided in the cover part of the outer cap allows the nozzle of the pressing head to pass through, so that the main body part of the outer cap is fitted to the inner cap and a ratchet mechanism is formed between the outer cap and the inner cap. Engage. Furthermore, a suction tube is attached to the lower end of the pump, the lower end side of the pump is inserted into the mouth of the container in which a predetermined amount of liquid is stored, the outer cap is rotated, and the inner cap is placed on the neck of the container. The peripheral wall portion of the container is screwed together, and the neck portion of the container and the inner cap are engaged with each other by a lock mechanism to form an unused dispenser.

8). How to use When an unused dispenser is brought into a normal use state in which liquid is ejected by pushing down the pressing head, the cover portion of the outer cap is cut off along the fragile portion and removed. At this time, the stopper can be removed by removing the cover portion of the outer cap. Then, by removing this stopper, the pressing head can be pushed down, and the liquid contained in the container can be discharged. Thus, in normal use, the stopper cannot be removed unless the cover of the outer cap is removed.
However, it is possible to forcefully remove the pressing head from the upper end of the pump stem by pulling the pressing head of the dispenser in an unused state by force, and take out the liquid contained in the container from the upper end of the pump stem. Although it is possible, if the pressing head is removed from the top end of the stem and then reattached to the top end of the stem, the top end of the stem will enter the protruding sheath cylinder of the inner cap. The nozzle cannot be reattached to the upper end of the stem and cannot be returned to an unused state. In addition, since the stem and the pressing head are mounted with a close contact member in a sealed state so as not to leak, the mounting of the pressing head needs to be performed while the stem is pressed down.
When the inner cap is removed from the neck of the container and the liquid in the container is taken out from the mouth of the container, the outer cap is fitted to the inner cap and the outer cap is attached. Can not be operated. When the inner cap is rotated in a direction to release the screwing of the inner cap to the neck of the container through the outer cap, the outer cap is moved by the ratchet mechanism provided between the inner cap and the outer cap. Cannot engage with the inner cap and the outer cap is idle, and the inner cap cannot be removed from the neck of the container.
When the inner cap is rotated in the direction in which the inner cap is attached to the mouth of the container via the outer cap, the inner cap and the outer cap are engaged with each other by a ratchet mechanism. The inner cap rotates together with the outer cap, and the inner cap can be more securely screwed onto the neck of the container.
The container of the present invention is suitable as a container for preventing foreign matter from entering after unauthorized use or opening, such as a cosmetic container and a medical container.

The stopper 6 is protruded in a state where the axial direction of the stopper 6 is aligned with the axial direction of the protruding sheath tube portion 39 and the protruding sheath tube portion 39 is in contact with the pair of guide ribs 63 of the stopper 6. By pressing against the sheath tube portion 39, the main body portion 61 of the stopper 6 is elastically deformed to expand the insertion opening 62, and the protruding sheath tube portion 39 is fitted and attached in the main body portion 61 of the stopper 6. .
From this state, the nozzle part 55 of the pressing head 5 enters the open part 76c of the covering cylinder part 76 of the outer cap 7, and the contact of the nozzle part 55 of the pressing head 5 with the peripheral surface part 76b of the covering cylinder part 76 is avoided. The opening 76c of the outer cap 7 is inclined at a predetermined angle, for example, 22.5 ° downward, and the lower end of the cap body 71 of the outer cap 7 is fitted from the nozzle portion 55 of the pressing head 5 I will match. At this time, as shown in FIG. 1 (b), the cap body 71 of the outer cap 7 is inserted while the nozzle portion 55 of the pressing head 5 is fitted into the open portion 76 c of the covering cylinder portion 76 of the outer cap 7. The cap body 71 of the outer cap 7 is externally fitted to the peripheral surface portion 32 of the inner cap 3 while gradually rotating the outer cap 7 to be vertically fitted to the peripheral surface portion 32 of the inner cap 3. At the same time, the engaging rib 74 of the outer cap 7 is engaged with the lower end edge of the peripheral surface portion 32 of the inner cap 3 so as to prevent it from coming off and is plugged. At this time, the upper end edge of the reduced diameter portion 32d of the inner cap 3 is fitted to the fitting step portion 73 of the outer cap 71, and the bulging portion 32c of the inner cap 3 is brought into close contact with the widened recess portion 71d of the outer cap 7. Further, the inclined surface 38a of each ratchet tooth 38c of the ratchet member 38 of the inner cap 3 and the inclined surface 72a of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 are engaged and engaged. Further, the covering cylinder portion 76 of the outer cap 7 covers the stopper 6 attached to the protruding sheath cylinder portion 39 of the inner cap 3 over the substantially circumferential direction, and covers the stopper 6 so that it cannot be removed. The
Further, from this state, the lower end side of the pump body 41 of the pump 4 is inserted into the mouth portion 23 of the container 2 filled with a predetermined amount of liquid L, and the inner cap 3 is inserted into the neck portion 22 of the container 2. After the outer cap 7 is fitted, the outer cap 7 is rotated so that the female screw 33 of the inner cap 3 is screwed into the male screw 24 of the container 2, and any one of the locking ratchets 36 of the inner cap 3 is engaged. The center piece 26a of each latching piece 26 of the container 2 is engaged with the teeth 36c and locked by the lock mechanism 35, so that the unused sealed container 11 shown in FIG. At this time, the ratchet mechanism 37 constituted by the ratchet member 38 of the inner cap 3 and the ratchet member 72 of the outer cap 7 is used to screw the female screw 33 of the inner cap 3 and the male screw 24 of the container 2 through the outer cap 7. The inner cap 3 is prevented from being removed from the mouth 23 of the container 2 so that it cannot be rotated in the direction of releasing the engagement.

<In use>
A method of using the dispenser 1 of this embodiment will be described. The discharge device 1 of the unused closed container 11 shown in FIGS. 1A and 1B discharges the liquid L by a predetermined amount from the discharge hole 55a of the pressing head 5 by the pressing operation of the pressing head 5. In a normal use state that can be used, the bent piece 77 of the outer cap 7 is pulled away from the cap body 71 of the outer cap 7 by holding the bent piece 77 of the outer cap 7 with a finger or the like. The covering cylinder part 76 of the outer cap 7 is cut off in the circumferential direction along the fragile part 77 b, and the covering cylinder part 76 is removed from the cap body 71 of the outer cap 7. At this time, since the covering cylinder portion 76 of the outer cap 7 is removed from the cap body 71, the stopper 6 can be removed from the protruding sheath cylinder portion 39 of the inner cap 3 in the radial direction, and the stopper 6 is removed. By pushing the guide rib 63 in the direction or the like, the main body portion 61 of the stopper 6 is elastically deformed and the insertion opening 62 is expanded, and the stopper 6 is removed from the protruding sheath tube portion 39 of the inner cap 3. As a result, the stopper 6 is removed from the projecting sheath tube portion 39 of the inner cap 3 so that the pressing head 5 can be pushed down, and the pressing head 5 is pushed down to be accommodated in the container 2. The liquid L can be used by being discharged from the discharge hole 55a of the press-down head 5 by a predetermined amount by the pumping operation by the pump 4.

<Preventing re-installation of the pressure head when not in use>
The pressing head 5 is forcibly removed from the upper end of the stem 42 of the pump 4 by, for example, pulling the pressing head 5 from the dispenser 1 of the unused closed container 11, so that the stem 42 to which the pressing head 5 is attached. It is also assumed that the liquid L is taken out from the upper end of the. However, in this case, if the pressing head 5 is removed from the upper end of the stem 42 and then the pressing head 5 is pressed against the upper end of the stem 42 to be attached again, the stem 42 resists the elastic force of the built-in spring mechanism. Thus, before the stem 42 is pushed down to a position where the pressing head 5 can be attached to the upper end of the stem 42, the lower end of the peripheral surface portion 53 of the pressing head 5 is moved into the protruding sheath tube portion 39 of the inner cap 3. Since the presser head 5 comes into contact with the upper end of the main body 61 of the stopper 6 and cannot be pushed down further, the presser head 5 cannot be reattached to the upper end of the stem 42 and returned to the unused state. I can't. Further, when the pressing head 5 is removed from the upper end of the stem 42, the stopper 6 attached to the protruding sheath cylindrical portion 39 is removed by the upper retaining rib 39 c provided on the protruding sheath cylindrical portion 39 of the inner cap 3. Since the stopper 6 cannot be pulled out, the pressing head 5 cannot be reattached to the upper end of the stem 42 after the stopper 6 is pulled out, so that the pressing head 5 cannot be pushed down.

<Preventing removal of inner cap when not in use>
When the inner cap 3 of the discharge device 1 of the closed container 11 in an unused state is removed from the mouth 23 of the container 2 and the liquid L in the container 2 is to be taken out from the mouth 23 of the container 2, this inner cap Since the outer cap 7 is fitted to the outer cap 3 and the outer cap 7 is attached, the inner cap 3 is rotated in a direction to release the screwing of the female screw 33 of the inner cap 3 with respect to the male screw 24 of the container 2 via the outer cap 7. In this case, the inclined surface 36a of each ratchet tooth 36c of the ratchet member 38 of the inner cap 3 and the inclined surface 72a of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 come into contact with each other. Whether the ratchet teeth 36c of the 38 member and the ratchet teeth 72c of the ratchet member 72 of the outer cap 7 do not engage with each other, and the outer cap 7 is idled , It is impossible to remove the inner cap 3 from the container 2 mouth 23. On the other hand, when the inner cap 3 is rotated in the direction in which the female screw 33 of the inner cap 3 is screwed into the male screw 24 of the container 2 via the outer cap 7, each ratchet tooth of the ratchet member 38 of the inner cap 3 is rotated. The vertical surface 36b of 36c and the vertical surface 72b of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 come into contact with each other, and the ratchet teeth of both members are engaged. The inner cap 3 can be screwed and attached to the mouth 23 of the container 2 more reliably.

<Virgin maintenance function>
In this embodiment, a stopper 6 for preventing the pressing head 5 of the discharger 1 from being pushed down is attached to the protruding sheath cylinder portion 39 of the inner cap 3, and this stopper 6 is covered by the covering cylinder portion 76 of the outer cap 7. The state in which the cap main body 71 of the outer cap 7 is externally fitted to the peripheral surface portion 32 of the inner cap 3 is moved to the lower end edge of the peripheral surface portion 32 of the inner cap 3 by the engaging rib 74 of the outer cap 7. The ratchet mechanism 37 formed between the inner cap 3 and the outer cap 7 prevents the inner cap 3 from being removed from the mouth portion 23 of the container 2. For this reason, in the unused state, the outer cap 7 cannot be removed from the inner cap 3, and the stopper 6 is made removable by removing at least the covering cylinder portion 76 of the outer cap 7. Is not removed from the protruding sheath tube portion 39 of the inner cap 3, the pressing head 5 cannot be pressed down to discharge the liquid L stored in the container 2 from the discharge hole 55 a of the pressing head 5. At this time, when the stopper 6 can be removed by removing the covering cylinder portion 76 of the outer cap 7 or the like, it is returned to the unused state before the covering cylinder portion 76 of the outer cap 7 is removed. Therefore, it is possible to reliably prevent the stopper 6 from being removed and the inner cap 3 from being removed in an unused state, and it is possible to reliably prevent the liquid from being extracted from the container 2 in an unused state, so-called trial use. The state can be reliably maintained.
In particular, the ratchet mechanism 37 formed between the inner cap 3 and the outer cap 7 rotates the inner cap 3 in a direction in which the female screw 33 of the inner cap 3 is screwed into the male screw 24 of the container 2 via the outer cap 7. In this case, the vertical surface 36b of each ratchet tooth 36c of the ratchet member 38 of the inner cap 3 and the vertical surface 72b of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 come into contact with each other, and each ratchet tooth is engaged. Thus, the inner cap 3 can be rotated together with the outer cap 7, and the operation of attaching the inner cap 3 to the neck portion 22 of the container 2 by screwing more securely is enabled. On the other hand, when the inner cap 3 is rotated in a direction in which the female screw 33 of the inner cap 3 is released from the male screw 24 of the container 2 via the outer cap 7, the ratchet mechanism 37 rotates the ratchet member of the inner cap 3. The inclined surfaces 38a of the 38 ratchet teeth 38c and the inclined surfaces 72a of the ratchet teeth 72c of the ratchet member 72 of the outer cap 7 come into contact with each other, and the ratchet teeth are not engaged, and the outer cap 7 is idled. For this reason, the inner cap 3 cannot be removed from the mouth 23 of the container 2 via the outer cap 7, and the container formed by the female screw 33 of the inner cap 3 unless the outer cap 7 is removed from the inner cap 3. The inner cap 3 cannot be removed from the mouth portion 23 of the container 2 by releasing the screwing of the second male screw 24.

In addition, after the covering cylinder portion 76 that is a stopper cover for the outer cap 7 of the closed container 11 in the unused state is cut along the fragile portion 77b, the outer cap 7 can be returned to the unused state before being cut off. Therefore, the unused sealed container 11 can be more reliably held, and the return to the unused state after being once used can be reliably prevented.
Further, a locking mechanism 35 is formed by the locking piece 26 provided on the neck portion 22 of the container 2 and the locking ratchet 36 of the inner cap 3, and the female screw 33 of the inner cap 3 is screwed into the male screw 23 of the container 2. The engagement mechanism C of the ratchet mechanism 37 between the outer cap 7 and the inner cap 3 when rotated in the direction of the lock mechanism 35 when the female screw 33 of the inner cap 3 is screwed into the male screw 23 of the container 2. The engagement torque A is set to be larger than the engagement torque A, and the non-engagement torque of the ratchet mechanism 37 is against the locking mechanism 35 when the internal thread 33 of the inner cap 3 is released from the threaded engagement with the external thread 24 of the container 2. It is set smaller than the release torque B. When the outer cap 7 is rotated in a direction in which the female screw 33 of the inner cap 3 is screwed into the male screw 24 of the container 2, the inner cap 3 can be rotated together with the outer cap 7, and the locking piece 26 and the inner cap of the container 2 can be rotated. 3 and the locking ratchet 36 can be engaged with each other and locked by the lock mechanism 35 to prevent it from coming off. At the same time, the female screw 33 of the inner cap 3 is screwed into the male screw 24 of the container 2, and the locking piece 26 of the container 2 is engaged with the locking ratchet 36 of the inner cap 3 and locked by the locking mechanism 35. As compared with the case, the internal thread 3 of the inner cap 3 can be released from the male thread 24 of the container 2 to make it difficult to remove the inner cap 3 from the mouth 23 of the container 2. Therefore, removal of the inner cap 3 from the mouth portion 23 of the container 2 can be more reliably prevented by torque balance.

<Reduced remaining amount, nozzle direction regulation>
In addition, each of the outer peripheral surface 39a of the protruding sheath tube portion 39 of the inner cap 3 and the inner peripheral surface 53a of the peripheral surface portion 53 of the pressing head 5 is formed in an octagonal shape in the radial direction cross section, so that the mounting direction of the pressing head 5 is changed. It becomes possible to position. For this reason, by positioning the mounting direction of the pressing head 5, the container 2 can be given directionality, and the front and back surfaces of the container 2 can be determined. The positions can be specified, and when the plurality of containers 2 are displayed, the directions of all the pressing heads 5 can be easily aligned in one direction, and the aesthetics when these containers 2 are displayed can be improved. At the same time, each of the outer peripheral surface 39a of the protruding sheath tube portion 39 of the inner cap 3 and the inner peripheral surface 53a of the peripheral surface portion 53 of the pressing head 5 is formed into an octagonal shape in the radial direction cross section, whereby the protruding sheath tube portion 39 and the insertion recess 54a, the pressing head 5 cannot be rotated in the circumferential direction only by applying a small force, and only when a certain amount of force is applied, the protruding sheath tube portion 39 and the insertion recess 54a Since the push-down head 5 can be rotated in the circumferential direction because the fitting is displaced, the container 2 can be attached to the container 2 by adjusting the mounting direction of the push-up head 5 in accordance with the position of the suction tube attached to the lower end of the pump body 41 of the pump 4. The liquid L accommodated can be discharged without leaving more reliably, and the usability of the discharge device 1 in the use state can be improved. Further, the inner peripheral surface 61a of the main body portion 61 of the stopper 6 has an octagonal cross section in the radial direction, so that when the stopper 6 is fitted and attached to the protruding sheath tube portion 39 of the inner cap 3, the circumferential direction is positioned. Thus, rotation of the stopper 6 in the circumferential direction can be prevented. In addition, as the outer peripheral surface 39a of the protruding sheath cylinder portion 39 of the inner cap 3 and the inner peripheral surface 53a of the peripheral surface portion 53 of the pressing head 5, when a predetermined force is applied, the protruding sheath cylinder portion 39 and the insertion recess 54a In order to allow the pressing head 5 to rotate in the circumferential direction by shifting the fitting, it is preferable to form a polygon having a radial cross section of a hexagon or more.

Further, the retaining rib 39c provided on the protruding sheath tube portion 39 of the inner cap 3 prevents the stopper 6 from being pulled upward when the pressing head 5 is removed from the upper end of the stem 42 of the pump 4. Even in the state where the pressing head 5 is removed from the upper end of the stem 42 of the pump 4, the stopper 6 cannot be removed laterally by the cover by the covering cylinder portion 76 of the outer cap 7, and the stopper 6 is prevented by the retaining rib 39c. Since the pressing head 5 is removed from the upper end of the stem 4 and the stopper 6 is removed, the pressing head 5 is attached again and the pressing head 5 can be reliably prevented from being pushed down. Further, it is possible to more reliably hold the sealed container 11 in the unused state.
Further, since the shaft-like portion 44 of the stem 42 of the pump 4 is covered with the protruding sheath tube portion 39 and the stopper 6 is attached to the protruding sheath tube portion 39, the pressing head 5 is moved from the upper end of the stem 42. After removing the liquid L accommodated in the container 2 from the upper end of the stem 42 and performing a trial use or the like, when the pressing head 5 is to be reattached to the upper end of the stem 42, the upper end of the stem 42 is Enters the protruding sheath tube portion 39 of the inner cap 3 and before the stem 42 is pushed down to a position where the pressing head 5 can be attached to the upper end of the stem 42, the lower end of the peripheral surface portion 53 of the pressing head 5 is the main body of the stopper 6. The pressing head 5 cannot be pushed down further, and the pressing head 5 cannot be attached to the upper end of the stem 42 again. Et al., Can not be returned to the unused state again. At this time, when the pressing head 5 is removed from the upper end of the stem 42, the stopper 6 attached to the protruding sheath cylinder 39 by the upper retaining rib 39 c provided on the protruding sheath cylinder 39 of the inner cap 3. Since the stopper 6 cannot be pulled upward, the pressing head 5 cannot be reattached to the upper end of the stem 42 so that the pressing head 5 can be pushed down. Accordingly, it is possible to more reliably hold the closed container 11 in the unused state, and to reliably prevent the return to the unused state after removing the pressing nozzle 5 and taking out the liquid L from the container 2.

Further, an annular convex portion 45b is integrally provided on the outer peripheral surface 45a of the head mounting portion 45 of the stem 42 of the pump 4, and the convex mounting portion 45b leads to the mounting cylinder portion 54 of the pressing head 5 by the head mounting portion 45. In this structure, the number of parts can be reduced and the structure can be reduced compared to a structure in which another member such as an O-ring is attached to the head mounting portion 45 of the stem 42 to prevent the fitting from being retained. In addition to simplification, when the push-up head 5 is mounted on the head mounting portion 45 of the stem 42 and assembled, the convex portion 45a is deformed by being scraped or crushed. After the detachment, when the pressing head 5 is attached to the head mounting portion 45 again, the pressing head 5 is not easily retained by the convex portion 45a. 5 can be more reliably prevented trial use of the liquid L in the container 2 by removing from the upper end of the stem 42. And since a pump cannot be removed freely, a pump cannot be removed and a foreign material cannot be mixed.
Further, an upper die (not shown) is provided above the upper end edge of the peripheral surface portion 71b of the outer cap body 71 covering the outer cap 7, and a lower die (not shown) is provided below the upper end edge of the peripheral surface portion 71b. Since the outer cap 7 can be formed by a combination of three molds, the outer cap 7 can be formed by a combination of three molds. Thus, the outer cap 7 can be easily manufactured.
