Article 30, Paragraph 2 of the Patent Act applies Date of distribution: June 3, 2020 Place of distribution: Gadelius Medical Co., Ltd.

The present invention relates to a tool (hereinafter simply referred to as a "push pump tool") for use in a push pump that discharges liquid (including gel; the same applies hereinafter) contained in a container body.

Liquid drugs and the like are stored in relatively hard plastic containers, such as high-density polyethylene, which has excellent chemical resistance. A push pump may be attached to the mouth of the container, and by pressing the push pump, an appropriate amount of liquid contained in the container can be discharged.

In recent years, from the viewpoints of ease of transportation and storage, manufacturing cost, and ease of disposal, a bag-shaped container body for containing a liquid made of a flexible plastic material has been proposed. In the case of a flexible container body, there may be a problem that the container body deforms when the push pump is pressed, making it impossible to press the push pump. Therefore, the following push pump tools have been developed.

Japanese Patent Application Publication No. 7-223689 Japanese Patent Application Publication No. 2015-199541

Patent Document 1 discloses a push pump tool that includes a bag-like container body (storage body), a push pump (pump mechanism), and a hard box body. The container body includes an opening body having an outlet, a lid attachment part, and a box body locking part, and the box body has a locking part at the upper end that locks the box body locking part of the mouth body. It has a wall. By locking the box body locking part to the locking wall part, storing the container body inside the box body, and attaching the push pump to the lid mounting part, the push pump can be used even if the container body is flexible. It is configured so that it can be pressed.

Patent Document 2 discloses a push pump tool that uses a push pump and a support device that includes a support leg member that comes into contact with the bottom surface of a flexible container body and a pouring pipe that is provided with an expandable bottom pouring tube. has been done. Since the support leg members support the push pump, even if the container body is flexible, it is possible to prevent the container body from deforming due to the pressure of the push pump, and it is possible to discharge liquid.

However, since the push pump tools disclosed in Patent Documents 1 and 2 have a large number of parts, it takes a lot of man-hours to assemble them, and there is also a problem that a relatively large amount of valuable resources are used.

Therefore, an object of the present invention is to provide a push pump tool that has a simple configuration and can be easily installed.

The present invention is a push pump tool that is placed on an upwardly opened box body in which a push pump is attached to the mouth part and a flexible container body containing liquid is housed.
The plate-shaped base is

A push pump tool mounted on an upwardly opened box housing a flexible container body in which a liquid is stored and a push pump is attached to the mouth part, the push pump tool comprising:
The plate-shaped base is
It is supported by two opposing sides and has a load capacity that will not break even if a load of 6.9 kgf is applied to the center.
an extending portion that abuts at least a pair of opposing edges of the opening and extends outward from the edges;
comprising a hole for locking the mouth or push pump;
The problem was solved by a push pump tool in which the hole was rectangular .

According to the present invention, if the plate-shaped base is placed on the opening of the box in which the container body is housed, and the mouth of the container body or the push pump is locked in the hole, the push pump Since tools can be assembled, the configuration is simple and can be easily installed.

In particular, in the case of liquids with low fluidity and high viscosity, such as special gels used in ultrasonic echo diagnosis, a large force is applied when the push pump is pressed. The base of the push pump tool is supported by two opposing sides and has a load capacity that will not break even when a load of 6.9 kgf is applied to the center, so it can be suitably used as a push pump for discharging gel.

In addition, if the dimension of the extending part is 5 mm or more, the stability of the push pump tool will be increased, and the push pump tool will not suddenly enter the box when the push pump is pressed. Falling situations can be prevented.

Additionally, if the hole is made up of two straight lines and two circular arcs, or if one arc is larger than the other, the area of the hole will be wider, and you will be able to insert your hand through the hole and find the main body of the container. This makes it easier to grasp the mouth part and make it protrude from the hole, making it easier to assemble.

In addition, if the straight line is configured to have a tapered shape, the opening of container bodies or push pumps of different sizes can be locked in the hole, so the push pump can be used with various container bodies or push pumps. It can be a tool.

Furthermore, if the hole is made up of two straight lines and two arcs, one arc is larger than the other, and the other arc extends beyond the range of the straight line, then the other arc When the opening of the container main body or the push pump is locked by the straight part, the opening of the container main body or the push pump is locked by the straight part, so the position of the push pump is fixed, making it easier to press the push pump. be able to.

In addition, if the hole is rectangular or has a step, the area of the hole becomes wider, and you can insert your hand through the hole and grasp the opening of the container body, and it will not be possible to protrude from the hole. This makes it easier to assemble.

In addition, if the base is made of a paper material and the fiber direction is perpendicular to the straight line that defines the shortest distance between the hole and the edge of the base, it is easy to maintain strength and the push pump is environmentally friendly. It can be a tool.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 14. However, the present invention is not limited to this embodiment.

FIG. 1 is a front view of a push pump tool 10 according to a first embodiment of the present invention. Note that the rear view is also the same. Push pump tool 10 includes a base 12 . The base 12 is plate-shaped as shown in FIGS. 2 and 3. Although FIG. 3 is a right side view of the push pump tool 10, the left side view, top view, and bottom view are also the same. The base 12 is supported by two opposing sides and is made of a load-resistant material that will not break even when a load of 6.9 kgf is applied to the center. The material may be plastic or metal, but considering the environment and limited resources, paper is preferable. The base 12 also includes a hole 16 and an extension 14, as shown in FIGS.

As shown in FIG. 4, the push pump tool 10 is placed on a box body 28 that is open upward. Although the box body 28 has a quadrangular prism shape, it may have other shapes such as a cylindrical shape. The container body 22 is housed in the box body 28. The container body 22 is made of a flexible material such as plastic, and contains liquid. The mouth of the container body 22 protrudes through the hole 16, and a push pump 24 is attached to the mouth by threading. By pressing the nozzle 26 of the push pump 24, the liquid in the container body 22 can be discharged. Note that commercially available products can be used for the container body 22, push pump 24, and box body 28.

The extending portion 14 of the push pump tool 10 is configured to abut at least a pair of opposing edges of the opening of the box body 28 and to extend outward beyond the edges. In the case of the push pump tool 10, the extending portion 14 is configured to contact all four edges of the opening of the box body 28 and extend outward. The dashed line in FIG. 1 indicates a portion that comes into contact with the edge of the opening of the box body 28, and indicates the boundary between the base portion 12 and the extension portion 14.

As shown in FIGS. 1 and 2, the hole 16 of the push pump tool 10 is composed of two straight lines and two circular arcs. Here, one circular arc is configured to be larger than the other circular arc, and forms a large hole portion 18. With such a configuration, the range of the hole 16 (including the large hole when a large hole is formed; the same applies hereinafter) is widened, and it is possible to insert your hand through the hole 16 into the container body 22. The push pump tool 10 can be assembled more easily because the opening of the push pump tool 10 can be grasped and the push pump tool 10 can be easily protruded from the hole 16. Specifically, the mouth of the container body 22 is made to protrude at the position of the large hole 18, and then the mouth is slid in the other circular arc direction of the hole 16 to lock the mouth in the hole 16. I can do it. It goes without saying that the opening of the container body 22 or the push pump 24 may be engaged with the large hole 18 for use.

The size of the hole 16 is such that the opening of the container body 22 or the push pump 24 is locked therein. Specifically, a protrusion such as a flange formed at the mouth of the container body 22 is engaged with the linear portion or the other arcuate portion of the hole 16, or the bottom surface of the push pump 24 screwed into the mouth. is locked. FIG. 4 shows a state in which the bottom surface of the push pump 24 is engaged with the other arcuate portion of the hole 16.

As described above, according to the push pump tool 10, the plate-shaped base 12 is placed on the opening of the box body 28 in which the container body 22 is housed, and Since the push pump tool 10 can be assembled by locking the push pump tool 10 into the hole, the push pump tool 10 can be easily installed with a simple configuration. By pressing the nozzle 26 in this state, the liquid contained in the container body 22 can be discharged from the nozzle 26 even if the container body 22 is flexible.

By the way, as an example of a liquid with low fluidity and high viscosity, there is a special gel used when performing ultrasonic echo diagnosis. When this gel was discharged by a push pump, the load applied to the push pump was 6.9 kgf. In this regard, the base 12 of the push pump tool 10 is supported by two opposing sides and has a load capacity that will not break even when a load of 6.9 kgf is applied to the center, so it is suitable for the push pump 24 that discharges gel. can be used.

Further, it is preferable that the dimension of the extending portion 14 of the push pump tool 10 is 5 mm or more. With this configuration, the stability when the push pump tool 10 is placed on the box body 28 is increased, and when the nozzle 26 of the push pump 24 is pressed, the push pump tool 10 is unexpectedly placed inside the box body 28. Falling situations can be prevented.

When the base 12 of the push pump tool 10 is made of a paper material, the fiber direction thereof is perpendicular to the straight line that defines the shortest distance between the hole 16 and the edge of the base 12 (vertical straight line in FIG. 1). (in the left-right direction in FIG. 1). This is because the strength of the push pump tool 10 can be easily maintained and the push pump tool 10 can be made environmentally friendly. This also applies to other embodiments.

Other embodiments of the push pump tool of the present invention will be described below. Since the basic configuration is the same as the push pump tool 10, the different points will be explained. Note that in each embodiment, the front view and rear view are the same, and the right side view, left side view, top view, and bottom view are the same as FIG. 3.

In the push pump tool 10a shown in FIGS. 5 and 6, the straight portion of the hole 16a is shorter than the push pump tool 10. With this configuration, the range of the hole 16a is smaller than the hole 16 of the push pump tool 10, so the strength of the base 12 can be increased.

In the push pump tool 10b shown in FIGS. 7 and 8, the other circular arc bulges out from the range of the straight line to form a bulged portion 17b. With this configuration, when the mouth of the container body 22 or the push pump 24 (see FIG. 4) is engaged with the other arcuate portion, the mouth of the container body 22 or the push pump 24 is engaged with the straight portion. Since the push pump 24 is stopped, the position of the push pump 24 is fixed, and the nozzle 26 of the push pump 24 can be easily pressed.

In the push pump tool 10c shown in FIG. 9, a rectangular hole 16c is formed, and a large hole 18c is further formed by forming a step 17c. With this configuration, the range of the hole 16c is widened, and it becomes easier to insert your hand through the hole 16c, grasp the opening of the container body 22, and make it protrude from the hole 16c, making assembly easier. can.

As in the push pump tool 10d shown in FIG. 10, the hole 16d can also be composed of two straight lines and two circular arcs of equal size.

The push pump tool 10e shown in FIG. 11 has a hole 16e composed of two straight lines and two circular arcs of different sizes, and the straight lines are tapered. With this configuration, the opening of the container main body 22 or the push pump 24 of different sizes can be locked in the hole 16e, so the push pump tool 10e is compatible with various container main bodies 22 or push pumps 24. It can be done.

The push pump tool 10f shown in FIG. 12 has more stepped portions 17f than the push pump tool 10c shown in FIG. In this way, the rectangular hole 16f may have a multi-stage shape.

It is also possible to make the holes 16g, 16h circular as in the push pump tools 10g, 10h of reference examples shown in FIGS. 13 and 14. Such a configuration is suitable when the mouth of the container main body 22 protrudes from the holes 16g, 16h, the push pump 24 is screwed into the mouth, and the push pump 24 is locked in the holes 16g, 16h. ing. Since the range of the holes 16g, 16h can be minimized, the strength of the bases 12g, 12h can be easily maintained. Note that instead of the circular holes 16g and 16h, square holes may be used.

Up to this point, embodiments have been described in which the base of the push pump tool of the present invention is rectangular, but the base of the push pump tool may have other shapes, such as a circle.

As described above, according to the present invention, it is possible to provide a push pump tool that has a simple configuration and can be easily installed.
