  Patent Document 1 describes a support leg of the dispensing pump in which a tubular part is provided at the upper part and six legs that extend radially downward from the lower end part of the tubular part are provided at the lower part. In Patent Document 2, as in Patent Document 1, a supporting leg is provided with a tubular portion at the top and three to four legs extending radially downward from the lower end of the tubular portion at the bottom. Is described.

  However, in the leg member of the dispensing pump described in Patent Literatures 1 and 2, since the leg portion that opens downward from the lower end portion of the tubular portion is provided, the leg portion is delicate and fragile, Since the connecting part is also smoothly bent downward from the tubular part, it can be bent or bent when operating the pump to be pushed down by hand, so that the support capacity of the pumping pump cannot be secured sufficiently and can be disposable as a container body When a material made of a soft material is used, there is a problem in that the container main body is deformed when the dispensing pump is operated, and the dispensing pump cannot be used with good stability.

  Therefore, as described in Patent Document 3, the present applicant is a pumping pump support device that can be detachably attached to the mouth portion of the container body, and a pumping pipe that can be closely fixed to the suction pipe of the pump; A lower link provided on the pouring pipe so as to be freely opened and closed by the first opening / closing connecting portion, a guide ring externally fitted on the outer periphery of the pouring pipe above the first opening / closing connecting portion, and a guide ring An upper link that can be opened and closed by an opening and closing connection portion; and a third opening and closing connection portion that connects the upper link and the lower link with the vertical movement of the guide ring.

  However, in the natural state, due to the elasticity of the material of the synthetic resin material that constitutes the first and second opening / closing connecting portions, the leg member may be opened larger than the inner diameter of the mouth portion without being completely closed. When the dispensing pump is attached to the container main body, the leg member has to be operated by hand to the closed leg posture, and there is a problem that the hand becomes dirty with the contents attached to the leg member.

  Further, in Patent Document 3, in order to solve this problem, a plurality of locking claws are provided on the upper end portion of the guide ring so that the leg member is held in a closed leg posture, and is closely fixed to the suction pipe of the pump. If the locking pipe is provided with a locking projection that can be engaged with the locking claw from the upper side in the closed leg position, if the operating force of a certain value or more along the dispensing pipe does not act on the guide ring, the locking claw There has also been proposed a support device configured so as not to get over the locking protrusion.

  However, as described in Patent Document 3, when the locking claw and the locking projection are provided, the support device is inserted into the container body from the mouth, and the lower end of the leg member is brought into contact with the bottom surface of the container body. Therefore, when switching the leg member held in the closed leg position to the open leg position, it is necessary to apply a relatively large operating force to the pumping pump so that the locking claw can get over the locking protrusion, When the support device is pressed, the leg member does not open smoothly because sufficient repulsive force does not act from the bottom of the flexible packaging container, so some users may be confused or uneasy about how to operate it. There was a case.

  Further, in the support device described in Patent Document 3, when the support device is removed from the container main body in a closed leg posture, the plurality of leg members are arranged substantially vertically along the extraction pipe, and thus adhere to the leg member. The contents that have been dripping may stain the floor. Further, in the closed leg posture, since the dimensional difference between the diameter of the circumscribed circle of the lower end portions of the plurality of leg members and the inner diameter of the mouth portion is relatively small, there is a problem that the extracted support device cannot be smoothly inserted into the container body. is there.

  On the other hand, Patent Document 1 discloses a support device having a throttle ring that operates a plurality of legs held in an open leg posture by the elasticity of the material by pulling the support device out of the container body together with the dispensing pump. Is described. However, even in the support device described in Patent Document 1, because the support legs are arranged at the center of the plurality of leg members, the leg members can be closed by the aperture ring only up to a substantially vertical position along the support legs. A configuration in which the lower end portions of the plurality of leg members are disposed on the inner side of the upper end portions and closed in a closed leg posture has not been proposed.

  The object of the present invention is to facilitate the switching operation from the closed leg position to the open leg position, and when the container body is extracted from the container body, the contents attached to the leg member can be prevented from dripping and It is another object of the present invention to provide a support device for a pouring pump, a pouring pump using the support device, a mouth portion of a container main body to which the pouring pump is attached, and a pouring container.

In the held state, the leg member 35 is inserted into the mouth portion 13a of the container main body 11 from the distal end side, and the support device 30 is assembled to the container main body 11 together with the dispensing pump 20. At this time, as shown in FIG. 15, the lower end portion of the aperture ring 50 abuts on the upper end portion of the mouth portion 13 a or the holding portion 13 d and is extracted from the leg member 35, and is loosely fitted to the upper support leg 32. Fitted. When the cap member 23 of the extraction pump 20 is screwed into the screw portion 13b formed on the outer peripheral surface of the mouth portion 13a, the drawing ring 20 is fixed to the mouth portion 13a. 50 is pushed downward by the packing 24 provided in the cap member 23, and as shown in FIG. 14, the ring portion 52 gets over the holding portion 13d and is held between the holding portion 13d and the locking portion 13b. Thus, the throttle ring 50 is held in the mouth portion 13a so as not to drop into the container main body 11. Further, as shown in FIG. 14, by tightening the cap member 23 to the screw portion 13b, the packing 24 is pressed against the upper end portion of the mouth portion 13a, and the dispensing pump 20 is assembled in a liquid-tight manner to the container body 11. . On the other hand, as shown in FIG. 13, the leg member 35 from which the aperture ring 50 has been extracted is opened by the elasticity of the material in the released posture, which is open rather than the drooping posture in the vertical direction, and is indicated by a two-dot chain line in FIG. In this way, the leg opening guide surface 41 at the lower end of the lower link 37 abuts against the bottom surface 14 of the container main body 11, so that the leg opening guide surface 41 extends along the bottom surface 14 as shown by a dashed line in FIG. 13. The leg is opened to the open leg position by moving outward. In this way, with the leg member 35 switched to the open leg position, as shown in FIG. 1, the operation portion 22 of the dispensing pump 20 is pushed downward to dispense the contents.

  On the other hand, when the container main body 11 is replaced with a refillable container main body 11 by using up the contents, etc., the cap member 23 is loosened and the support device 30 is extracted from the container main body 11 together with the dispensing pump 20. Become. At this time, the leg member 35 returns to the release posture illustrated in FIG. 13 closed by the elasticity of the material rather than the open leg posture.

Are fitted on the upper portions of the three leg members 35, and the three leg members 35 are held in a closed leg posture by the aperture ring 50. At this time, since the operation resistance when the diaphragm ring 50 is extracted from the mouth portion 13a is set to be larger than the operation resistance when the diaphragm ring 50 is externally fitted to the leg member 35, the diaphragm ring 50 is located inside the mouth portion 13a. The throttle ring 50 held in the mouth portion 13a is automatically linked to the operation when the support device 30 is pulled out from the container main body 11 together with the dispensing pump 20 while the support member 30 is pulled out. And the leg member 35 is switched to the closed leg posture. Thus, in a state where the leg member 35 is switched to the closed leg posture by the throttle ring 50, the ring device 52 of the throttle ring 50 gets over the holding unit 13 by further operating the support device 30 together with the dispensing pump 20 in the pulling direction. The throttle ring 50 is detached from the mouth portion 13a, and the dispensing pump 20 and the support device 30 can be extracted from the container body 11.

By increasing the strength rigidity of the link 37, the support strength of the pumping pump 20 by the support device 30 is increased, and the stability of the pumping pump 20 when the contents are discharged by operating the pumping pump 20 is improved. Can be improved. Further, in a state in which the aperture ring 50 is externally fitted to the leg member 35 and the plurality of leg members 35 are held in a closed leg posture, the lower end side of the leg member 35 is more constricted toward the center side of the support leg 31 than the upper end side. It becomes. For this reason, even if the contents adhere to the leg member 35 when the support device 30 is extracted from the container body 11, the contents are held between the adjacent leg members 35, and the lower end portion of the leg member 35. It is prevented from dripping from. Further, in the closed leg posture, the circumscribed circle of the lower end portions of the plurality of leg members 35 becomes smaller as compared with the case where the leg member is held in the hanging posture as in the support device described in Patent Document 3, and accordingly, The support member 30 can be smoothly inserted into the container body 11 by improving the insertability of the leg member 35 into the mouth portion 13a.

Further, in the state where the support device 30 is assembled to the container main body 11 together with the dispensing pump 20, the throttle ring 50 is held in the mouth portion 13 a by the holding portion 13 d, so that the support device 30 is removed from the container main body 11 together with the dispensing pump 20. In conjunction with the extraction operation, the aperture ring 50 held by the holding portion 13d can be automatically fitted to the leg member 35 to switch the leg member 35 to the closed leg posture. Therefore, the leg member 35 can be switched to the closed leg posture without touching the diaphragm ring 50, and the hand is not soiled by the diaphragm ring 50 to which the contents are attached.

  Furthermore, since the upper link 36 and the slide member 34 are made of an integrally molded product of synthetic resin material, and the lower link 37 and the support leg 31 are made of an integrally molded product of synthetic resin material, the support device 30 is It becomes possible to form without difficulty, and the number of parts of the support device 30 can be reduced as compared with the case where the upper link 36 and the lower link 37 are formed of separate members. Moreover, since the support apparatus 30 can be easily assembled by fitting the bearing part 36a to the axial part 37a from the upper side in the state which combined both members, it is preferable. Further, due to the elasticity of the material in the upper connecting portion 39 and the lower connecting portion 38 formed of an elastic hinge, when the aperture ring 50 is extracted from the leg member 35 and the leg member 35 is opened, the leg member 35 moves to the release posture side. Since it rotates, it becomes possible to easily operate the leg member 35 to the open leg posture.

  In order to apply the present invention to a container body having a wide mouth portion, as shown in FIG. 17, when using a throttle ring 50 </ b> A having a diameter larger than that of the throttle ring 50, side operation is performed. Instead of the surface 45, one or more operation ribs 60 projecting outward are formed at the upper part of the upper ring 36 of each leg member 35, and the upper part of the operation rib 60 is moved upward in the closed leg posture. Accordingly, the operation surface 61 inclined toward the center side of the slide member 34 can be formed. In this case, as shown in FIG. 17, instead of the restriction protrusion 42, a restriction protrusion 42 </ b> A that protrudes outward can be formed at the lower end portion of the operation rib 60. With this configuration, the height of the operation rib 60 protruding outward is adjusted according to the inner diameter of the aperture ring 50A, so that the containers of various mouths can be used without changing the thickness of the upper link 36. On the other hand, the present invention is preferable because it can be easily applied.
