Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage container for storing a viscous fluid substance such as an adhesive, and in particular, a storage container for storing a viscous fluid substance such as an adhesive, and in particular, a storage container that prevents the fluid substance from accumulating at the outlet of the container and from remaining inside the container. The present invention relates to a fluid substance storage container, characterized in that it can be discharged in a single manner.

BACKGROUND ART Conventionally, a container having a structure shown in FIG. 1 has been used as a storage container for storing a viscous fluid substance such as an adhesive. In the figure, 1 is a deformable storage container body made of a material such as polyethylene, 2 is a lid of the storage container body, and 3 is a container for discharging a fluid substance. In this case, as shown in Fig. 2, with the nozzle 3 of the storage container at an angle below or diagonally below the storage container body 1, apply pressure in the directions of arrows A and B to open the storage container. In contrast, in the case of the storage container having the above structure, pressing force is applied by the grip force of the hand to compress and deform the storage container main body 1. The container body 1 has a weak restoring force after deformation due to the comparative terms and conditions. Therefore, during or after discharging the fluid substance 4 in the container, there is a drawback that the fluid substance remains at the tip of the nozzle 3 or drips from the nozzle 3°. In particular, when the fluid substance is a fast-curing adhesive, the adhesive remaining at the tip of the nozzle 3 hardens and blocks the outlet of the nozzle 3, resulting in a problem of poor adhesive flow. .

In addition, when there is little fluid substance 4 remaining in the storage container body 1, the fluid substance 4 will remain in the container even if the storage container body IK is applied with a repeated pressing force, and the usage efficiency of the fluid substance 4 will deteriorate. There was a drawback.

Furthermore, if the nozzle 3 is placed above the storage container body 1, the fluid substance 4 in the container cannot be discharged, and when applying a pressing force to the storage container body 1, the tip of the nozzle 3 is directed in the targeted direction. There was a drawback that work efficiency and work reliability deteriorated due to deviation from the position.

The present invention aims to eliminate the above-mentioned drawbacks, and by providing a retractable storage container body and a means for compressing the storage container body, the fluid substance in the container will not remain at the tip of the discharge nozzle. It is an object of the present invention to provide a fluid substance storage container that does not drip from a nozzle and has high work efficiency and work reliability.

Hereinafter, the present invention will be described in detail based on the drawings. Figures 3(A) and 3(B) are diagrams showing the structure of a storage container according to a first embodiment of the present invention. FIG. 3(CB) is a front view, and FIG. 3(CB) is a sectional view taken along the line T-I in FIG. 3(A). In addition, in all the figures of the embodiment, parts having the same functions are given the same reference numerals, and repeated explanations thereof will be omitted.

In FIGS. 6(A) and CB), 5a and 5b are a main bellows and an auxiliary bellows respectively constituting the storage container main body, and 6 is a nozzle for discharging the fluid substance 7. The main bellows and the auxiliary bellows 5a, 5b are integrally connected at a portion 5C and housed in a bellows protection capsule 8. Further, the bellows protective capsule 8 is covered with lids 11&, 111) via airtight gaskets 9a, lQa, lQb at both ends thereof.
is sealed by. The tip of the main body bellows 5a is a tube 5d having a diameter smaller than the diameter of the bellows.
The nozzle 6 and the lid 11 are connected by a screw carved in a part of the nozzle 6 and the lid 11.
It is removably connected to a.

The bellows protection capsule 8Vc is attached with a handle 12 that can be supported by hand, and inside this handle 12, air can be sent into the inside of the bellows protection capsule 8 which is hermetically sealed. An air bag 13 is housed therein. The air bag 13 is made of a rubber-like material that can be easily compressed when held by hand and has a high restoring force, and the part 13a to be held by hand is exposed on the outside of the handle 12.

A floating ball 141 in which air can only flow in one direction at the top and bottom of the air bag 13! An air valve 14.15 containing a valve L, 15a is installed. Further, one end 141) of the air valve 14 is connected to the bellows protective capsule 8 so that the air in the air bag 13 can be sent into the inner portion 8a of the bellows protective capsule. moreover,
A part of the air valve 14 has an inner portion 8 of a bellows protective capsule.
a [A vent hole 140 is provided to allow the introduced air to escape.

Next, how to use the storage container having such a structure will be explained. When the air inside the air bag 13 is compressed by pressing the exposed part taa of the air bag 13 in the direction of the arrow A in FIG. In an attempt to escape from the valves 14 and 15, the floating balls 14a, 15& provided inside the air valves are pushed in the directions of arrows B and C. As a result, Figure 4 (A) and (B)
As shown in the partially enlarged sectional view of K air valve 14.15,
The floating ball 14a inside the air valve 14 is pushed upward, the inlet of the valve is opened, and the air inside the air bag 13 flows upward. Furthermore, the floating ball 15a inside the air valve 15 is pushed down to block the inlet of the valve and prevent the air inside the air bag 13 from escaping to the outside.

Furthermore, if you stop compressing the air bag 13 while blocking the tip of the vent 140 with your finger, the air bag 13 will try to return to its original shape due to its own restoring force and the difference in air pressure between the inside and outside of the air bag. , the floating balls 14a and tel inside the air valve are pushed in the direction opposite to arrows B and C. As a result, Figure 5 (A)
, CB), the floating ball 14a inside the air valve 14 is pushed down to block the inlet of the valve, and the inner part 8 of the bellows protective capsule is shown.
This prevents the air sent into the air bag 13 from flowing back toward the air bag 13. Further, the floating ball 15a inside the air valve 15 is pushed upward, opening the inlet of the valve, and air flows into the inside of the air bag 13 from the outside.

Therefore, by continuously repeating the compression and opening of the exposed portion 13a of the air bag 13 while blocking the tip of the vent hole 14C with your finger, the air valve 15, the air bag 13, and the air valve 1
The inner part 8a of the capsule for bellows protection from the outside via 4
Air can be continuously pumped into the As a result, the internal pressure of the bellows protective capsule inner part 8a increases, the main bellows 5a and the auxiliary bellows 5b are pushed in the direction of the arrow in FIG. 3, and the fluid substance 7 inside the bellows is discharged from the tip of the nozzle 6. .

After the required amount of fluid has been discharged, when the finger blocking the tip of the vent 14Q is released, the compressed air trapped inside the bellows protective capsule inner portion 8a flows out through the vent 140. Therefore, the air pressure inside the bellows protection capsule inner portion 8a decreases, and an amount of air corresponding to the volume of the compressed portions of the restoring force bellows 5a and the auxiliary bellows 5b of the main bellows 5a and the auxiliary bellows 5b flows from the outside through the nozzle 6 to the main body. It is sent inside the bellows. Due to this flow of air, the fluid substance remaining inside the nozzle 6 is pushed back into the bellows of the main body. No more dripping of fluid substances.

Note that as the fluid substance 7 inside the main body bellows 5a decreases, air also accumulates inside the main body bellows 5a.
In this case as well, by continuously repeating the compression and release of the exposed portion 13a of the air bag 13 while blocking the tip of the vent 14 with your finger, the fluid substance 7 can be easily drawn from the tip of the nozzle 6. Can be discharged. Particularly in this case, in the storage container of the present invention, since the part that stores the fluid substance 7 is composed of the main bellows 5a and the auxiliary bellows 5b,
Fluid substances can be discharged more efficiently than conventional containers. That is, if the exposed portion 13a of the air bag 13 is repeatedly compressed and released in a state where the fluid substance 7 in the main body bellows 5a becomes very small and air is accumulated in the main body bellows 5a, the inside of the bellows protective capsule As described above, the compressed air of 8a causes the main bellows 5a and the auxiliary bellows 5 to
b are pushed together in the direction of the arrow in FIG.

At this time, the air inside the main bellows 5a is exhausted from the nozzle 6 as the main bellows 5a contracts, but air remains inside the main bellows even when the main bellows 5a is most deflated. However, if the exposed portion 13a of the air bag 13 is repeatedly compressed and released, the inner portion 8aK of the bellows protective capsule
When further air is sent in, the compressed air causes the sixth
As shown in the figure, the auxiliary bellows 5b expands and enters into the contracted main bellows 5a. As a result, the air remaining in the main body bellows Sa is completely exhausted. Furthermore, when the exposed portion 13& of the air bag 13 is repeatedly compressed and opened, the auxiliary bellows 5b further expands, and the stretched auxiliary bellows 5b pushes out the fluid substance remaining in the main body bellows 5a. The fluid substance can be discharged without remaining inside the main body bellows 5a.

In addition, when filling the storage container with a fluid substance, the nozzle 6 and the lid 1 are integrally fixed to the tube 5d by a screw cut into a part of the tube 5d at the tip of the body bellows 5a.
After sequentially removing parts 1a, the integrated main body bellows 5a
Then, take out the auxiliary bellows 5b from the bellows protection capsule 8, and pour the fluid substance into the bellows from the tip of the tube 5d to tow it.

7(A) and 7(B) are diagrams showing the structure of a storage container according to a second embodiment of the present invention, FIG. 7(A) is a front view, and FIG. 7(B) is a FIG. 2 is a cross-sectional view taken along the line ■-■ in Figure (A). In the figure, main bellows 5 as auxiliary bellows 5b,
Nozzle 6, fluid substance 7, airtight maintenance para-? y9a, 1
0a, 10b, lid 11a1 and air valve 15 are the same as those of the first embodiment.

At the top of the bellows protection capsule 8, a stopper 16 and a guide groove 17 are provided to prevent the integrated main body bellows 5a and auxiliary bellows 5b from returning in the direction opposite to the arrow direction, and to keep the bellows protection capsule 8 airtight. It is set up in such a way that it maintains its character. The stopper 16 overflows into the guide groove 17 and moves in the direction of the arrow in such a state that the fluid substance 7 in the main body bellows 8 decreases and air accumulates in the bellows, so as to minimize the space where air accumulates. Can be done. In addition, the rear lid 11b of the bellows protection capsule 8 is provided with an internal bellows protection capsule 8a.
An air valve 18 is installed to allow the escape of compressed air. This air valve 18 is shown in FIG.
As shown in the enlarged sectional view in B), normally the valve 18a is pressed in the direction of arrow A by the spring 18b, so the vent of the air valve 18 is blocked by the valve 18a.
Fig. 8(A))% When the knob 18C attached to the tip of the valve 18a is pushed in the direction of arrow B, the valve 18a also moves in the direction of arrow B and the vent of the air valve 18 opens, so that the bellows can be protected. The compressed air inside the capsule 8a can be exhausted to the outside through the air valve 18 (FIG. 8(B)). As shown in FIG. 7, a handle 12 made of a material that can be easily compressed by hand and has a certain degree of shape restoring force is attached to the bellows protection capsule 8. This handle 12 is made solid except for the parts that can be compressed by hand so that it can support the entire storage container. That is, the handle 12 of the storage container in this embodiment has both the roles of the handle 12 of the storage container and the air bag 13 in the first embodiment. An air valve 14,15 is attached to the handle 12, one end 14,b of the air valve 14 is connected to the bellows protective capsule so that the air in the handle 12 can be directed into the inner part 8a of the bellows protective capsule. 8 is connected.

To use a storage container with such a structure, compress and open the handle 12 by hand to send the air inside the handle through the valve 14 to the inner part 8a of the bellows protection capsule, and to release the air inside the bellows protection capsule. This embodiment is the same as the first embodiment except that the compressed air in the portion 8a is exhausted to the outside through the air valve 18, so a detailed explanation will be omitted.

As described above in detail with reference to the embodiments, according to the present invention, air in a compression container that can be easily compressed by hand is fed into the bellows protection capsule, and the fed compressed air is used to compress the bellows protection capsule. Since a strong pressing force can be applied to the stored container main body, materials with strong restoring force can be used for the main bellows and the auxiliary bellows that constitute the storage container main body. Therefore, when the compressed air inside the bellows protection capsule is exhausted to the outside after discharging the fluid material, the strong restoring force of the main bellows and the auxiliary bellows causes the air to flow forcefully from the nozzle tip, causing the fluid material remaining in the nozzle portion to can be pushed back into the storage container body,
This eliminates the problem of fluid substances remaining in the nozzle part or dripping from the nozzle tip, which was a problem with conventional storage containers. Furthermore, the main body of the storage container is composed of two bellows, the main bellows and the auxiliary bellows, and the auxiliary bellows can be extended to fit inside the main bellows when the main bellows is in its most contracted state. The air and fluid material can be discharged until no air and fluid material remain in the storage container, and the usage efficiency of the fluid material is significantly improved compared to conventional storage containers, making it economical. For the same reason, the fluid substance can be easily discharged even if the nozzle is directed above the storage container body. Furthermore, the tip of the nozzle does not deviate from the target direction when compressing the storage container body and discharging the fluid substance. Therefore, work efficiency and work reliability are significantly improved compared to conventional storage containers.

In the above description, an example has been described in which the storage container main body is composed of two bellows, but it is not limited to this, and can be widely used as long as it is made of an expandable material. Furthermore, the air valves are not limited to those shown in the embodiments, and can be widely used as long as they fulfill the same role.
