Also, as a preferred embodiment of the present invention, the following configuration can be provided in any combination with the above-described configuration of the present invention.

It is also possible to connect the tip end portion of the upper link to the upward connecting portion provided between the middle portion of the lower link and the tip portion as the third opening / closing connection portion. In this case, since the lower link is in contact with the container bottom in the closed leg state and the lower surface of the lower link is in wide contact with the container bottom, the support leg can be stably and firmly reinforced. Stability during operation can be improved.

It is also possible to connect the tip of the lower link as the third opening / closing connector to an upward connector provided between the middle part of the upper link and the tip. In this case, since the upper connecting portion comes into contact with the bottom of the container in the closed leg state, a wide open leg state can be obtained, and the support leg can be stably and firmly reinforced. Can be improved.

Also, it can be configured by a sliding surface formed so that the contact surface of the upper link or the lower link contacting the bottom of the container body in the closed leg state is slid in the opening leg direction. Even when the closed leg state is tight and the sliding angle with the container bottom becomes small, the upper and lower links can be smoothly opened by the contact surface sliding in the leg opening direction.

It is also possible to provide a resilient means for imparting elasticity between the stopper and the slide member so that the open leg state can be maintained elastically.

The upper link and the lower link are closed and inserted from the mouth of the container main body, and the upper or lower link contacts the container bottom so that the container gradually expands along the container bottom. It is also possible to do. In this case, it is possible to provide a pouring container having a deep depth to which the pouring pump can be easily attached.

It is also possible to configure the lower surface of the lower link so as to make surface contact with the upper surface of the bottom of the container body. In this case, the contact area of the lower link with the bottom of the container main body can be increased to prevent a large load from acting locally on the bottom of the container main body when the dispensing pump is operated.

Also, it can be configured such that the upper and lower links are further closed in the closed leg state than in the vertical direction. In this case, it is possible to easily insert the lower end portion of the link into the mouth portion of the container main body with both the legs closed, and the assembling property of the dispensing pump to the container main body can be improved.

According to the pumping pump support device according to the present invention, as described in claim 1 of the claims, the pumping pump support device is detachably attachable to the mouth of the container body, A support leg extending downward from the dispensing pump, a lower link provided on the support leg so as to be opened and closed by a first opening / closing connection portion, and an outer fit to the support leg at a position higher than the first opening / closing connection portion. A slide member; an upper link provided on the slide member by a second opening / closing connection portion; and a third opening / closing connection portion for connecting the upper link and the lower link in an openable / closable manner with the vertical movement of the slide member. By providing, when the pouring pump is attached to the mouth portion of the container main body while the lower link and the upper link are held in the closed leg state, the tip end portion of any one of the links comes into contact with the container bottom portion. With the upward movement of the slide member Link is open leg in conjunction, to migrate both the link is pouring pump to open leg state capable of supporting. And in this open leg state, since the weight of the extraction pump is received by the support device, the container body can be made independent even when a container made of a soft material is adopted. In addition, even when the operation portion of the dispensing pump is pushed downward, the pushing operation force acting on the dispensing pump is received by the support device, so that the dispensing pump can be operated with high stability. Moreover, since the pushing operation force hardly acts on the container body, even when a container made of a soft material is used as the container body, it is possible to prevent deformation during operation of the dispensing pump.

In addition, since both the links can be opened and closed by the slide member that can move up and down along the support legs and the first to third opening and closing connecting portions, the legs that can be elastically deformed as in the prior art are used. Compared to the case, it is possible to give sufficient strength and rigidity to both links, and the stability of the posture of the dispensing pump during the dispensing operation can be further improved. In addition, since both links open with the upward movement of the slide member along the support leg, by restricting the upward movement of the slide member with respect to the support leg in the open leg state, both links are more than in the open leg state. Further, it is possible to reliably prevent the movement to rotate upward, and to keep both links in an open leg state with good stability.

In addition, since the support leg member of the present invention has a configuration in which the leg is opened in contact with the bottom of the container, the support leg member that is elastically opened in the return state in the conventional natural state passes the mouth of the container body at the same time. The support member of the present invention can be applied to a container having a narrow shoulder and a container having a deep depth as compared with the case where the container wall near the mouth is feared to be caught and a large container shoulder is required. There is also an effect that can be used easily. Furthermore, since the support leg member of the present invention does not depend on the pouch shape as long as the surface necessary for the development of the lower link is secured, the degree of freedom in selecting the pouch is increased.

Further, according to the present invention, since the suction pipe for supplying the contents to the dispensing pump is constituted by the support leg as described in claim 2, it is compared with the case where the suction pipe is provided inside the support leg. Thus, the number of parts can be reduced and the production cost of the entire dispensing container can be reduced. In particular, a short upper suction pipe is detachably attached to the pumping pump, and a connection portion that can be fitted into the upper suction pipe is formed at the upper end portion of the support leg, and the support leg is connected to the lower end portion of the upper suction pipe. It is preferable that the suction pipe is constituted by the upper suction pipe and the support leg by connecting the parts. In this case, for example, by adjusting the length of the pipe-shaped upper suction pipe having a simple configuration made of, for example, a silicon tube according to the height of the container body, the container body of various sizes with different heights can be used. Thus, a common support device having the same size can be applied, and it is not necessary to manufacture a plurality of support legs having different lengths, which is preferable in reducing the manufacturing cost of the support device.

Further, according to the present invention, at least two or more sets of the first to third opening / closing connecting portions and the upper and lower links are provided around the support leg at intervals in the circumferential direction. Thus, it becomes possible to support the dispensing pump with higher stability. In particular, when three or more sets are provided, the dispensing pump can be reliably and stably supported without adopting a wide lower link. Further, when two or more sets of the first to third opening / closing connecting portions and the upper and lower links are provided in this way, the specific one or more upper and lower links are configured to be slightly longer than the other links. In the closed leg state, it is preferable that the lower ends of the specific upper and lower links are arranged at a position lower than the lower ends of the other links. In this case, when the pouring pump is inserted into the container main body in the closed leg state, the specific link comes into contact with the bottom of the container main body first and is operated to the open leg side, and then the plurality of links are opened. Because it is operated to the side, the operation force at the initial stage of the opening operation is set smaller than when simultaneously opening multiple sets of links, and the multiple sets of links are opened and operated easily and smoothly. Is possible.

According to a fourth aspect of the present invention, the support leg and the lower link, the slide member and the upper link, or the upper link and the lower link are connected openably and closably. By having the configuration in which the 3 open / close connecting portion is formed of the hinge connecting portion, there is an effect that each link can be reliably opened / closed around the hinge axis.

According to the present invention, as described in claim 5, the hinge connecting portion has a structure comprising a hinge connecting portion that is formed into a thin wall by integral molding of plastic and connected openably and closably. There is an effect that the link, the slide member and the upper link, or the upper link and the lower link can be integrally formed by a thin hinge connecting portion.

Further, according to the present invention, as described in claim 6, the other bearing portion is fitted to one hinge shaft portion formed by individually forming the hinge connecting portions of the first, second or third opening / closing connecting portions. By having the structure which consists of the connected hinge connection part, there exists an effect which can be assembled | attached integrally by fitting the other bearing part to one hinge shaft part of the member shape | molded separately.

Further, according to the present invention, as described in claim 7, since the support leg is provided with a stopper for stopping the slide member at the upward movement position or the downward movement position, the open leg state or the closed leg state is maintained. There is an effect that can be attached, and there is an effect that it is easy to attach the pouring pump through the mouth of the container body by maintaining the closed leg state.

Further, according to the present invention, as described in claim 8, by providing engagement with the stopper, a closing leg locking portion for holding the slide member in the closed leg state is provided on the support leg, and along the support leg with respect to the slide member. Because the operation force of a certain value or more acts, the stopper can get over the locking part for the closed leg, so it is possible to hold both links stably in the closed leg state, The operability of inserting the support device into the mouth of the container main body can be improved. For example, in order to replace the pouring pump and its supporting device with another container body, when the pouring pump and its supporting device are extracted from the container body, both links can be securely held in a closed leg state, When installing, both links in the closed leg state can be inserted into the mouth of another container body as they are, and the pumping pump and its supporting device can be attached, without touching both links with the contents attached, The dispensing pump and its support device can be attached to another container body.

Then, the hinge connection bearing 26 provided at the tip of the upper link 22 provided at the lower end thereof is fitted to the hinge shaft 16 of the upper connection portion 15 of the lower link 12 provided at the lower end of the large-diameter pipe portion 2. Can be assembled and assembled as described in other figures.

In this assembled state, as shown in FIG. 1 or FIG. 2 and the like, the guide ring 20 contacts the stopper 6 at the position where the lower surface of the lower link 12 is in contact with the bottom 43 of the container body 40 and becomes horizontal. The link 22 supports the lower link 12 in the maximum open leg state, and can counter the lateral force applied to the support leg 1. When the upper link 22 is closed downward together with the lower link 12, the guide ring 20 moves to the lower end portion of the large-diameter pipe portion 2, and the upper link 22 and the lower link 12 are shown in FIGS. Or as shown in FIG. 7, it will be in a closed leg state.

In this closed leg state, the lower link 12 is configured such that the lower side of the upper link 22 is in close contact with the upper side of the lower link 12, so that the upper link 22 in the closed leg state does not protrude outwardly as shown in FIG. The outer diameter at can be reduced. Moreover, the front-end | tip part of the lower link 12 contact | abutted to the bottom part 43 of the container main body 40 in the closed leg state comprises the smooth sliding surface 18 in the leg opening direction.

In the first embodiment, the combination of the upper and lower links 22 and 12 has three sets of opening and closing legs in three directions, but the combination can be appropriately selected to include two or more sets including one set. . For small containers, it can be up to 6 sets, for large containers it can be more, and even 12 sets or more.

As shown in FIG. 1, the pouring pump support device 10 having the above-described configuration has the upper end portion 8 of the support leg 1 adhered and fixed to the cylindrical portion 32 of the pouring pump 30. In the large-diameter pipe portion 2 at the lower end of the support leg 1, the guide pump 20 is pushed down and the upper and lower links 22, 12 are closed, and the pouring pump 30 is linked to the mouth portion 41 of the container body 40. It will be inserted from the side.

At this time, when the lower end portion of the large-diameter pipe portion 2 approaches the bottom portion 43 of the container main body 40, the lower end portion of the lower link 12 of the support device 10 comes into contact with the bottom portion of the container main body and starts the leg opening. It is pushed by the upper link 22 and moves toward the upper part of the large-diameter pipe portion 2, and as shown in FIG. 1, at the position where the lower surface of the lower link 12 is in surface contact with the bottom 43 of the container body 40 horizontally. The guide ring 20 is brought into contact with and locked against the stopper 6 to strongly prevent the support leg 1 from rolling and to support it strongly.

That is, when the pump operation unit 34 is pushed down in the state shown in FIG. 1 or 10 in which the dispensing pump 30 is mounted on the container body 40 formed of a flexible bag body, the force passes through the pump unit 35 and the cylinder unit 32. Since the guide ring 20 transmitted to the support leg 1 and locked to the stopper 6 is integrated with the upper link 22 and the lower link 12 and is received by the flat bottom 43 of the container body 40 in surface contact with the installation surface. The dispensing pump 30 can be operated with good stability. Further, since the operating force during operation of the pouring pump 30 is received by the support device 10 and hardly acts on the container main body 40, the container main body 40 is made of a soft material, and the pouring pump 30 is used. It is possible to prevent the appearance from being deteriorated due to the deformation of the container body 40 during the operation.

In addition, when removing the pouring pump 30 from the mouth part 41 of the container main body 40, even if the upper and lower links 22 and 12 are opened, the upper part 22 is closed by the mouth part 41 hitting and left as it is. In this case, if the guide ring 20 is lowered downward and the upper and lower links 22 and 12 are closed after the detachment, the container body 40 can be mounted again.

In addition, the specific one or more upper and lower links 22 and 12 are configured to be slightly longer than the other links 22 and 12, and in the closed leg state, the lower ends of the specific upper and lower links 22 and 12 It is preferable that the links 22 and 12 are configured so as to be disposed at a position lower than the lower end portions. With this configuration, when the pouring pump 30 is inserted into the container main body 40 in the closed state, the specific links 22 and 12 first come into contact with the bottom 43 of the container main body 40 and are operated to the open leg side. Then, since the plurality of links 22 and 12 are operated to the opening leg side, the operation force at the initial stage of the opening operation is set smaller than the case of opening the plurality of links 22 and 12 at the same time. It is possible to easily and smoothly operate the links 22 and 12 in the open state.
