The detachably mounted retaining ring between the lower ram and the top wall portion of the inner cover is covered by the cover portion of the outer cover, and the outer portion of the outer cover is fitted over the inner cover through the outer cover The engagement portion is held by the engagement of the engagement portion with the inner cover, and the removal preventing unit for preventing the inner cover from being detached from the neck of the container is disposed between the inner cover and the outer cover. Therefore, through the fitting of the inner cover and the outer cover, the outer cover cannot be removed from the inner cover, and at least the cover portion of the outer cover is removed to form a detachable retaining ring, if the retaining ring is not removed from the lower pressing head and When the top wall portion of the inner lid is detached, when the lower ram is pressed downward, the liquid stored in the container is not discharged from the discharge hole. In particular, when the cover portion of the outer cover is removed or the like to form a detachable retaining ring, since it is impossible to return to the state before the cover portion or the like of the outer cover is removed, the retaining ring in the unused state can be surely prevented. The disassembly and removal of the cover can prevent the liquid from being withdrawn from the container in an unused state and can be kept in an unused state.

5. When the inner cover is screwed on the neck of the container, since the inner cover is covered by the outer cover, the torque cannot be directly transmitted to the inner cover, and the torque applied to the outer cover is transmitted to the inner cover through the ratchet mechanism. When the outer cover is rotated in the direction in which the inner cover is screwed on the neck of the container, the inner cover and the outer cover are engaged by the ratchet mechanism, and since the outer cover rotates together with the inner cover, the inner cover is attached to the neck of the container. The operation can be carried out more precisely. When the outer cover is rotated in the direction in which the inner cover is unscrewed on the neck of the container, the inner cover and the outer cover are not engaged by the ratchet mechanism, and the outer cover is idling. Therefore, if the outer cover is not detached from the inner cover or the like, the inner cover cannot be detached from the neck of the container, so that it can be more accurately kept unused.

6. By separating the cover portion of the outer cover from the main body portion of the outer cover, the cover portion of the outer cover is broken along the fragile portion, so that the retaining ring is detachable. Therefore, by removing the retaining ring, the lower pressing nozzle can be pressed downward, and the liquid stored in the container can be discharged. As a result, after the outer cover is disconnected along the fragile portion in the unused state, the state before the outer cover is disconnected cannot be restored, so that the unused state can be more accurately maintained, and once it is used, it can be confirmed. Prevents reverting to an unused state.

7. A locking mechanism is provided between the neck of the container and the inner cover, and the engagement torque of the ratchet mechanism when rotating in the direction in which the inner cover is mounted on the neck of the container is greater than when the inner cover is attached to the neck of the container The locking torque of the locking mechanism is large, and the engagement torque of the ratchet mechanism when rotating in the direction of detaching the inner cover from the neck of the container is relieved when the inner cover is detached from the neck of the container against the locking mechanism. The torque is small, and the design is such that when the outer cover is rotated in the direction of screwing the inner cover on the neck of the container, the inner cover and the outer cover of the ratchet mechanism are engaged, whereby the outer cover and the inner cover can be rotated together. The neck portion and the inner lid of the container can be engaged by the locking mechanism, and it is difficult to remove the inner lid from the neck portion of the container when the inner lid is attached to the neck of the container without using the locking mechanism. Therefore, on the basis of preventing the detachment of the inner cover by the ratchet mechanism, the engagement torque between the engagement direction and the detachment direction by the ratchet mechanism is compared with the engagement torque and the release torque generated by the lock mechanism. Torque balance can more accurately prevent the inner cover from being removed from the neck 22 of the container.

8. Since the retaining ring is located below the anti-dropping rib provided on the sheath of the inner cover and is covered by the cover portion of the outer cover, even if the lower pressing head is pulled out, the retaining ring can be prevented from being pulled upward. Therefore, even in a state where the lower pressing head is detached from the upper end of the pump shaft, as long as the cover portion of the outer cover is not removed, the retaining ring cannot be pulled upward due to the blocking of the detachment preventing rib, so the lower pressing head is removed. After the lower pressing head is installed again, it is possible to prevent the lower pressing head from being pressed down, and it is possible to more accurately remain unused.

9. forming an outer peripheral surface of the protruding sheath portion of at least a portion of the shaft protruding upward from the communication hole and an inner peripheral surface of the fitting recess portion of the lower pressing head into which the protruding sheath portion can be fitted, respectively forming a radial section It is a polygon, from which the orientation of the lower indenter can be determined. Therefore, by determining the orientation position of the lower pressing head, the container can be made directional, and the assembly procedure of the outer cover can be facilitated. Further, with respect to the fitting portion, the direction of the nozzle of the lower indenter can be changed by the elastic deformation of the member resin, and can be fixed at this position, so that the position of the residual amount of liquid and the pipette can be determined, and the inner solution can be used up. Further, since the front side and the back side can be determined, it is possible to determine the position of the label or the like, and when the plurality of containers are arranged or the like, all of the lower heads can be easily aligned in the same direction.

10. At least a portion of the shaft that protrudes upward from the communication hole is sheathed by the protruding sheath portion 39, and the protruding sheath portion is provided with an anti-falling rib, and a retaining ring is attached. Therefore, the lower pressing head is detached, and after the liquid contained in the container is taken out from the upper end of the shaft, if the lower pressing head is to be attached to the upper end of the shaft, the upper end of the shaft cannot enter the protruding sheath portion of the inner cover. The lower pressure nozzle cannot be installed again at the upper end of the shaft, and cannot be returned to the unused state, so that the unused state can be more accurately maintained, and the lower pressure nozzle can be more accurately prevented from being taken out and the liquid is taken out from the container. Then restore to the unused state.

The inner lid is attached to the neck of the container in which the liquid is stored, and includes a top wall portion provided with a communication hole that communicates with the mouth portion of the container, and a peripheral edge that surrounds the top wall portion and is screwed to the container. a cylindrical peripheral wall portion on the neck portion; the pump is inserted and attached to the communication hole of the inner lid, and at least a portion of the shaft that can be inserted downwardly in a state of being biased upward from the communication hole is upwardly The lower pressing head is disposed at an upper end of the pump shaft, and has a nozzle portion formed with a discharge hole; the discharge device is provided with a retaining ring for preventing downward pressing of the lower pressing head, and is disposed at a top of the lower pressing head and the inner cover The wall portion is detachably mounted, and has a cover portion that covers the retaining ring, a cylindrical body portion that is externally fitted to the inner cover, and a body portion that is externally fitted to the inner cover The outer cover of the engaging portion where the inner cover is engaged. The cover portion of the outer cover is provided with a notch portion for avoiding contact between the nozzle portion of the lower indenter and the cover portion when the outer cover is attached from the lower indenter side; and between the inner cover and the outer cover is provided to prevent from the neck of the container Remove the removal prevention unit of the inner cover. By fitting the outer cover and the inner cover, the outer cover cannot be removed from the inner cover, and at least the cover portion of the outer cover is removed to form a detachable retaining ring, if the retaining ring is not removed from the lower pressing head and the inner cover When the top wall portion is detached, the lower ram can not be pressed downward to discharge the liquid contained in the container. In particular, when the cover portion of the outer cover is removed or the like, and the detachable retaining ring is formed, the unused state before the cover portion of the outer cover is removed can not be restored.

When the spout of the present invention relatively rotates in the direction in which the inner lid is screwed on the neck of the container, since the inner lid and the outer lid are engaged, the outer lid and the inner lid rotate together, so that the inner lid can be more accurately When the neck portion of the container is attached to the neck of the container, the inner lid and the outer lid are not engaged with each other, and the outer lid is idly rotated. Therefore, if the outer cover is not detached from the inner cover or the like, the inner cover cannot be detached from the neck of the container. Separating the locking portion of the outer cover from the main body portion of the outer cover to disconnect the outer cover along the fragile portion, thereby detaching the cover portion of the outer cover from the inner cover to form a detachable state of the retaining ring . In this state, the state in which the lower pressure nozzle can be pressed downward is removed by the removal of the retaining ring, and the liquid stored in the container can be discharged. Therefore, the outer cover is disconnected along the fragile portion in an unused state. After that, it cannot be restored to the state before the cover was disconnected.

The spout of the present invention is provided with a locking mechanism for engaging the inner lid of the container when the inner lid is attached between the neck portion and the inner lid of the container, and is set to: attach the inner lid to the neck of the container The engagement torque of the ratchet mechanism when the direction is rotated is larger than the engagement torque of the lock mechanism, and is smaller than the release torque when the lock mechanism is detached from the neck of the container. When the outer cover is rotated in the direction of screwing the inner cover on the neck of the container, the inner cover and the outer cover of the ratchet mechanism are engaged, so that the outer cover and the inner cover can be rotated together, and the neck of the container can be made by the locking mechanism.

Further, in a state where the operation of the lower pressing head 5 is not pressed downward, that is, the protruding sheath portion 39 of the inner lid 3 is hardly inserted into the fitting recess portion 54a of the lower ram 5, as shown in Fig. 10, The retaining ring 6 is externally fitted from the lateral direction of the protruding sheath portion 39 of the inner lid 3, and a retaining ring 6 is attached between the falling-preventing ribs 39c of the protruding sheath portion 39 so that the lower pressing head cannot be pressed downward. 5 operations. At this time, the upper side fall prevention rib 39c provided in the protruding sheath tube part 39 of the inner cover 3 is formed, and the state in which the retaining ring 6 is pulled upward is prevented. Further, the axial direction of the retaining ring 6 is transmitted through the protruding sheath portion 39 between the pair of guiding ribs 63 of the retaining ring 6 in the axial direction of the protruding sheath portion 39. The ring 6 is pressed against the protruding sheath portion 39, and the body portion 61 of the retaining ring 6 is elastically deformed, and the insertion opening 62 is expanded, and the protruding sheath portion 39 is fitted and fitted in the body portion 61 of the retaining ring 6.

From this state, the nozzle portion 55 of the lower ram 5 enters the open portion 76c of the covered tubular portion 76 of the outer lid 7, and the contact between the nozzle portion 55 of the lower ram 5 and the circumferential surface portion 76b of the covered tubular portion 76 is prevented. The open portion 76c of the outer lid 7 is inclined downward at a predetermined angle, for example, 22.5°, and the lower end side of the lid body 71 of the outer lid 7 is fitted from the nozzle portion 55 of the lower ram 5 . At this time, as shown in Fig. 1(b), the nozzle portion 55 of the lower indenter 5 is fitted into the open portion 76c of the covered tubular portion 76 of the outer cover 7, and the cover body 71 of the outer cover 7 is externally fitted. When the outer cover 7 is slowly rotated and held vertically, the cover body 71 of the outer cover 7 is fitted to the peripheral surface portion 32 of the inner cover 3 while being fitted to the circumferential surface portion 32 of the inner cover 3, and at the same time The engaging rib 74 of the outer cover 7 is engaged with the lower end edge of the circumferential surface portion 32 of the inner lid 3, and is held to prevent falling off and to be sealed. At this time, the upper end edge of the reduced diameter portion 32d of the inner lid 3 is fitted to the fitting portion portion 73 of the outer lid 71, and the enlarged portion 32c of the inner lid 3 is tightly engaged with the expanded concave portion of the outer lid 7. Further, on 71d, the inclined surface 38a of each of the ratchet teeth 38c of the ratchet member 38 of the inner cover 3 and the inclined surface 72a of each of the ratchet teeth 72c of the ratchet member 72 of the outer cover 7 are engaged with each other. Further, the retaining ring 6 attached to the projecting sheath portion 39 of the inner cover 3 is sheathed in the circumferential direction by the covered tubular portion 76 of the outer cover 7, so as to be caught so that the retaining ring 6 cannot be detached.

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 in which the predetermined amount of the liquid L is stored, and the inner lid 3 is fitted to the neck portion 22 of the container 2 Rotating the outer cover 7 so that the female thread 33 of the inner cover 3 is screwed onto the male thread 24 of the container 2, so that any of the central piece 26a of each locking piece 26 of the container 2 and the locking ratchet 36 of the inner cover 3 The ratchet teeth 36c are engaged with each other, and are locked by the lock mechanism 35 to form the sealed container 11 in an unused state shown in Fig. 1(a). At this time, the ratchet mechanism 37 constituted by the ratchet member 38 of the inner lid 3 and the ratchet member 72 of the outer lid 7 forms a loop in which the female thread 33 of the inner lid 33 and the male thread 24 of the container 2 cannot be released via the outer lid 7. The direction of rotation is prevented from being detached from the mouth portion 23 of the container 2 of the inner lid 3.

<When used>

A method of using the spout 1 of the present embodiment will be described. By the operation of pressing down the lower ram 5, the discharger 1 of the sealed container 11 in the unused state shown in Figs. 1(a) and 1(b) is formed into a discharge hole from the lower ram 5 When 55a discharges a predetermined use state of the liquid L, the bent piece 77 of the outer cover 7 is caught by a finger or the like, and the bent piece 77 is pulled away from the cover main body 71 of the outer cover 7, so that the outer portion 7 is pulled out. The covered tubular portion 76 of the lid 7 is broken in the circumferential direction along the fragile portion 77b, and the covered tubular portion 76 is removed from the lid body 71 of the outer lid 7. At this time, the cover cylindrical portion 76 of the outer cover 7 is removed from the cover main body 71, and the retaining ring 6 is detached from the protruding sheath portion 39 of the inner cover 3 in the radial direction, and is detached from the retaining ring 6 by the detachment. The direction pushes the guide rib 63 or the like to elastically deform the main body portion 61 of the retaining ring 6, and the insertion opening 62 is expanded, and the retaining ring 6 can be detached from the protruding sheath portion 39 of the inner cover 3. As a result, the retaining ring 6 is detached from the protruding sheath portion 39 of the inner lid 3 to form a state in which the lower pressing head 5 can be pressed downward, and the downward pressing of the lower pressing head 5 becomes possible. The liquid L accommodated in the container 2 is discharged from the discharge hole 55a of the lower ram 5 by a predetermined amount by the operation of sucking up the pump 4, respectively.

<Prevent reinstallation of the pressing head under unused>

It is assumed that the lower pressing head 5 is pulled out or the like through the discharger 1 of the sealed container 11 in an unused state, and the lower pressing head 5 is forcibly removed from the upper end of the shaft 42 of the pump 4, and the lower side is attached thereto. The liquid L is taken out from the upper end of the shaft 42 of the indenter 5. However, in this case, after the lower ram 5 is detached from the upper end of the shaft 42 and the lower ram 5 is forcibly pressed against the upper end of the shaft 42 to be mounted, the shaft 42 resists the internal spring. The elastic force of the mechanism enters the protruding sheath portion 39 of the inner cover 3, and the shaft 42 is pressed to the position where the lower pressing head 5 can be mounted at the upper end of the shaft 42 because the lower end of the circumferential surface portion 53 of the lower pressing head 5 The upper end of the main body portion 61 of the retaining ring 6 is brought into contact with it, and the lower pressing head 5 cannot be further pressed downward. Therefore, the lower pressing head 5 cannot be attached to the upper end of the shaft 42 again, and cannot be returned to the unused state. Further, when the lower ram 5 is detached from the upper end of the shaft 42, the upper detachment preventing rib 39c provided through the protruding sheath portion 39 of the inner lid 3 cannot be attached to the protruding sheath portion 39. Since the retaining ring 6 is pulled upward, the lower pressing head 5 cannot be attached to the upper end of the shaft 42 after the retaining ring 6 is pulled out, and the lower pressing head 5 is pressed downward.

<Prevent removal of inner cover without use>

The inner lid 3 of the discharger 1 of the sealed container 11 in an unused state is detached from the mouth portion 23 of the container 2, and the liquid L in the container 2 is taken out from the mouth portion 23 of the container 2 because the inner lid is Since the outer cover 7 is fitted to the outer casing 3, it is necessary to rotate the inner cover 3 in the direction in which the female screw 33 that releases the inner cover 3 and the male screw 24 of the container 2 are screwed together via the outer cover 7. In this case, the inclined faces 36a of the ratchet teeth 36c of the ratchet member 38 of the inner cover 3 abut against the inclined faces 72a of the ratchet teeth 72c of the ratchet member 72 of the outer cover 7, the ratchet teeth 36c of the members of the ratchet 38 and The ratchet teeth 72c of the ratchet member 72 of the outer cover 7 are not engaged, and the outer cover 7 is idling, and the inner cover 3 cannot be detached from the mouth portion 23 of the container 2. On the other hand, when the inner lid 3 is rotated in the direction in which the female thread 33 of the inner lid 3 is screwed on the male thread 24 of the container 2 via the outer lid 7, the ratchet teeth 36c of the ratchet member 38 of the inner lid 3 are perpendicular to each other. The surface 36b abuts against the vertical surface 72b of each of the ratchet teeth 72c of the ratchet member 72 of the outer cover 7, and forms a state in which the ratchet teeth of the two members are engaged, so that the outer cover 7 and the inner cover 3 can be rotated together. The inner lid 3 can be more accurately screwed onto the mouth portion 23 of the container 2.

<Original state maintenance function>

In the present embodiment, the retaining ring 6 that prevents the operation of pressing the lower ram 5 of the discharger 1 downward is attached to the projecting sheath portion 39 of the inner cover 3, and the retaining ring 6 is covered by the covered tubular portion 76 of the outer cover 7. The cover body 71 of the outer cover 7 is fitted to the outer peripheral surface 32 of the inner cover 3, and the card is inserted through the engagement rib 74 of the outer cover 7 and the lower end edge of the peripheral surface 32 of the inner cover 3. Further, the prevention prevents the falling off, and the ratchet mechanism 37 formed between the inner lid 3 and the outer lid 7 prevents the inner lid 3 from being detached from the mouth portion 23 of the container 2. Therefore, in the unused state, the outer cover 7 cannot be detached from the inner cover 3, and the detachable retaining ring 6 is formed by removing at least the covered cylindrical portion 76 of the outer cover 7, etc., if the retaining ring 6 is not When detaching from the protruding sheath portion 39 of the inner lid 3, the lower ram 5 cannot be pressed downward to discharge the liquid L accommodated in the container 2 from the discharge hole 55a of the lower ram 5. At this time, when the covered tubular portion 76 of the outer cover 7 is removed or the like, and the detachable retaining ring 6 is formed, the unused state before the covered cylindrical portion 76 of the outer cover 7 cannot be restored, it is possible to By preventing the detachment of the retaining ring 6 in the unused state and the detachment of the inner lid 3, it is possible to surely prevent the liquid from being taken out from the container 2 in an unused state (so-called trial), and it can be surely kept in an unused state.

In particular, the ratchet mechanism 37 formed between the inner lid 3 and the outer lid 7 rotates the inner lid 3 in the direction of screwing the female thread 33 of the inner lid 3 on the male thread 24 of the container 2 via the outer lid 7, The vertical surface 36b of each of the ratchet teeth 36c of the ratchet member 38 of the inner cover 3 abuts against the vertical surface 72b of each of the ratchet teeth 72c of the ratchet member 72 of the outer cover 7, and the ratchet teeth of the both are engaged. The outer cover 7 and the inner lid 3 can be rotated together, and the operation of mounting the inner lid 3 more precisely on the neck portion 22 of the container 2 can be performed. On the other hand, when the ratchet mechanism 37 rotates the inner lid 3 through the outer lid 7 in the direction in which the female thread 33 of the inner lid 3 is unscrewed on the male thread 24 of the container 2, the respective ratchets of the ratchet member 38 of the inner lid 3 The inclined surface 38a of the tooth 38c abuts against the inclined surface 72a of each of the ratchet teeth 72c of the ratchet member 72 of the outer cover 7, and the ratchet teeth are not engaged with each other, and the outer cover 7 is idling. Therefore, the inner cover 3 cannot be detached from the mouth portion 23 of the container 2 through the outer cover 7, and if the outer cover 7 is not detached from the inner cover 3, the female thread 33 of the inner cover 3 and the container 2 are released. The inner cap 3 cannot be detached from the mouth portion 23 of the container 2 by the screwing of the male thread 24.

Further, after the covered tubular portion 76 as the baffle cover of the outer lid 7 of the sealed container 11 in the unused state is broken along the fragile portion 77b, the unused state before the outer cover 7 is broken can not be restored, so that the unused state is not restored. The hermetic container 11 in an unused state can be more accurately maintained, and once it is in the use state, it can be surely prevented from returning to the unused state.

Further, the 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 cover 3, and the outer cover 7 is screwed to the inner cover 3 on the male thread 23 of the container 2. When the direction of the female thread 33 is rotated, the engagement torque C generated by the ratchet mechanism 37 between the outer cover 7 and the inner cover 3 is set to be smaller than the female thread 33 of the inner cover 3 screwed on the male thread 23 of the container 2. The engagement torque A of the lock mechanism 35 at the time is large, and the non-engagement torque of the ratchet mechanism 37 is set to be lower than the rotation of the female screw 33 of the inner cover 3 against the male screw 24 of the container 2 against the lock mechanism 35. The release torque B is small. When the outer cover 7 is rotated in the direction of screwing the female thread 33 of the inner lid 3 on the male thread 24 of the container 2, the outer lid 7 and the inner lid 3 can be rotated together to make the locking piece 26 and the inner portion of the container 2 The locking ratchet 36 of the cover 3 is engaged and locked by the locking mechanism 35 to keep it from falling off. At the same time, the female thread 33 of the inner lid 3 is screwed onto the male thread 24 of the container 2 so that the locking piece 26 of the container 2 is engaged with the locking ratchet 36 of the inner lid 3 and locked by the locking mechanism 35. It is difficult to release the screwing of the female thread 33 of the inner lid 3 and the male thread 24 of the container 2 to detach the inner lid 3 from the mouth portion 23 of the container 2. Therefore, the inner cover 3 can be more reliably prevented from being detached from the mouth portion 23 of the container 2 by the torque balance.

<The amount of residue is extremely small, and the nozzle direction is limited>

Further, the outer circumferential surface 39a of the protruding sheath portion 39 of the inner lid 3 and the inner circumferential surface 53a of the circumferential surface portion 53 of the lower ram 5 are each formed into an octagonal radial cross section, and the mounting orientation of the lower ram 5 can be specified. position. Therefore, by specifying the mounting orientation position of the lower pressing head 5, the container 2 can be made directional, and the front and back sides of the container 2 can be determined, and the position of the label or the like can be determined on the container 2, and the plurality of containers 2 can be determined at the same time. When arranging or the like, all of the lower rams 5 can be easily aligned in the same direction, and the appearance of the containers 2 can be improved. At the same time, the outer circumferential surface 39a of the protruding sheath portion 39 of the inner lid 3 and the inner circumferential surface 53a of the circumferential surface portion 53 of the lower ram 5 are each formed into an octagonal radial cross section, and the protruding sheath portion 39 is transmitted. The fitting with the fitting recess 54a does not allow the lower ram 5 to rotate in the circumferential direction when only a small force is applied, and the fitting of the sheath portion 39 and the fitting recess 54a only when a certain amount of force is applied. The lower pressing head 5 is rotated in the circumferential direction, so that the mounting direction of the lower pressing head 5 is adjusted by the position corresponding to the suction pipe installed at the lower end of the pump body 41 of the pump 4, so that the container can be more accurately The liquid L accommodated in the inside 2 is discharged without any residue, and the usability of the discharge device 1 in the use state can be improved. Further, when the inner circumferential surface 61a of the main body portion 61 of the retaining ring 6 is formed into an octagonal radial cross section, and the retaining ring 6 is fitted and fitted to the protruding sheath portion 39 of the inner lid 3, the circumferential position can be determined. This prevents the retaining ring 6 from rotating in the circumferential direction. Further, as the outer peripheral surface 39a of the protruding sheath portion 39 of the inner lid 3 and the inner peripheral surface 53a of the circumferential surface portion 53 of the lower ram 5, it is preferable to form a polygonal shape having a hexagonal shape or more in a radial cross section so as to be applied in advance. When the force is applied, the fitting of the protruding sheath portion 39 and the fitting recess 54a is disengaged, so that the lower pressing head 5 can be rotated in the circumferential direction.

Further, the detachment preventing rib 39c provided in the protruding sheath portion 39 of the inner lid 3 prevents the retaining ring 6 from being pulled upward when the lower ram 5 is detached from the upper end of the shaft 42 of the pump 4, so that the retaining ring 6 is pulled upward. Even in a state in which the lower pressing head 5 is detached from the upper end of the shaft 42 of the pump 4, the retaining ring 6 cannot be detached from the lateral direction due to the covering action of the covering cylindrical portion 76 of the outer cover 7, due to the fall-preventing rib 39c Therefore, the retaining ring 6 cannot be pulled upward, so the lower pressing head 5 is detached from the upper end of the shaft 4, and the lower pressing head 5 is removed after the lower retaining ring 6 is removed, so that the lower pressing head 5 can be prevented from being pressed downward. The unused state of the hermetic container 11 can be more accurately maintained.

Further, the shaft portion 44 of the shaft 42 of the pump 4 is sheathed by the protruding sheath portion 39, since the retaining ring 6 is attached to the protruding sheath portion 39, the lower pressing head 5 is detached from the upper end of the shaft 42 When the liquid L accommodated in the container 2 is taken out from the upper end of the shaft 42 for trial or the like, and the lower head 5 is to be attached to the upper end of the shaft 42 again, the upper end of the shaft 42 enters the inner cover 3 In the protruding sheath portion 39, the shaft 42 is pressed until the lower pressing head 5 can be mounted at the position of the upper end of the shaft 42 because the lower end of the circumferential surface portion 53 of the lower pressing head 5 and the body portion 61 of the retaining ring 6 Since the upper end is in contact and the lower pressing head 5 cannot be further pressed down, the lower pressing head 5 cannot be attached to the upper end of the shaft 42 again, so that it cannot be restored to the unused state again. At this time, when the lower ram 5 is detached from the upper end of the shaft 42, the upper detachment preventing rib 39c provided on the protruding sheath portion 39 of the inner cover 3 cannot be placed on the protruding sheath portion 39. The installed retaining ring 6 is pulled upward, and the retaining ring 6 is pulled upward, and the lower pressing head 5 is again attached to the upper end of the shaft 42 so that an operation state in which the lower pressing head 5 can be pressed downward cannot be formed. Therefore, the unused state of the hermetic container 11 can be more accurately maintained, and the unused state after the liquid L is taken out from the inside of the container 2 can be prevented from being restored to the state where the lower pressure head 5 is removed.

Further, an annular convex portion 45b is integrally provided on the outer circumferential surface 45a of the head attachment portion 45 of the shaft 42 of the pump 4, and the head mounting portion 45 and the mounting cylinder portion 54 of the lower ram 5 are held by the convex portion 45b. The fitting is prevented from coming off and the seal is formed, and by such a design, the number of parts can be reduced as compared with a structure in which another member such as an O-ring is attached to the head mounting portion 45 of the shaft 42 to prevent falling off. When the lower ram 5 is assembled in combination on the head mounting portion 45 of the shaft 42 at the same time, since the convex portion 45a is deformed by cutting or abrasion or the like, once the lower ram 5 is attached from the head mounting portion 45 After the detachment, the lower ram 5 is again attached to the head mounting portion 45, so that the lower ram 5 is hard to be held by the convex portion 45a to prevent falling off, and the lower ram 5 can be more reliably prevented from passing through the shaft. The upper end of 42 is removed and the liquid L in the container 2 is tried. Moreover, since the pump cannot be freely loaded and unloaded, the pump cannot be disassembled and mixed with foreign matter.

Further, the upper side of the upper end edge of the circumferential surface portion 71b of the cap body 71 that covers the outer side of the outer cover 7 is an upper mold (not shown), and the lower side of the upper end edge of the circumferential surface portion 71b is a lower mold (not shown). As shown in the figure, the inner side of the outer cover 7 is a reduced diameter mold (not shown), and the outer cover 7 can be formed by a combination of a total of three molds, and the mold structure of the outer cover 7 can be formed. Simple, the outer cover 7 can be easily manufactured.
