  The present invention relates to a flowable substance storage container for storing a flowable substance such as a liquid or a zel-like substance therein, and in particular, a lid portion having an outlet for guiding the flowable substance from the inside to the outside, and a flow including the lid portion. The present invention relates to the structure of a storage container for chemical substances.

As a conventional fluid substance storage container, for example, there are containers described in Patent Document 1 and Patent Document 2. In the container described in Patent Document 1, the mouth part for taking out the contents in the container is formed of a hard material with poor flexibility so as not to deform the shape. For this reason, the opening shape is always open.

  The container described in Patent Document 1 is formed of a hard material with poor flexibility so that the outlet shape is not deformed when the fluid substance in the container is taken out. For this reason, there is a problem that it is not possible to prevent the intrusion of outside air from the mouth portion, and the backflow of the fluid substance or the impurities outside the container once into the container. For this reason, the content once taken out from the mouth tends to remain attached around the mouth. And the deposit | attachment oxidizes and changes in quality and soils the periphery of a mouth part. In addition, oxidative and altered contents, air, and the like are likely to enter the container, causing a phenomenon such as deterioration of the quality of the contents inside the container.

Moreover, the exit part of the container described in Patent Document 2 is formed by overlapping two flexible sheets. For this reason, when taking out the highly viscous content, there exists a subject that the state which the content adheres to the exit part after taking out and an exit part cannot be sealed may generate | occur | produce. In order to prevent this, it is necessary to forcefully apply force to seal the outlet.
In the first example of the container described in Patent Document 3, the discharge part is an elastic tubular body formed of a material having confidentiality and stretchability, and the diameter of the discharge port is zero in a normal state (when closed). . The pressure required to expand the diameter is the pressure from the center of the tubular body diameter toward the outer peripheral direction, whereas the direction of the pressure generated when the stored item is taken out is the vertical direction with respect to the tubular body. For this reason, since the expansion / contraction direction is orthogonal to the pressurization direction, it is impossible to expand the mouth of the tubular body by the pressure applied to the stored item, even if a material having excellent elasticity is used, and discharge can be performed. The amount is insignificant and not practical. Further, in the second example, an auxiliary holding body having spring property is attached to the distal end portion of the discharge portion elastic tubular body and tightened. For this reason, the external shape is complicated, and the discharge port and its periphery are easily dirty and difficult to clean. In addition, there are many parts and types of parts materials, and the manufacturing cost is high.

Further, in the container described in Patent Document 4, the check valve portion of the stopper has a plate-like elastic body provided with a cross-shaped slit across the inner and outer surfaces, and has a valve structure that can be bent and deformed in the thickness direction. However, when the plug is in a normal state, the sealed state of the slit portion is not established, and even a very small gap is in an open state. Further, since the slit portion is curved in a direction perpendicular to the plane, the restoring force is small. For this reason, the intrusion of outside air cannot be completely prevented. Moreover, although there are some differences depending on properties such as the viscosity of the stored item, leakage of the stored item cannot be completely prevented.
The present invention has been made for the purpose of solving such problems of conventional containers.

In order to solve the above-mentioned problems, the invention described in claim 1 of the present invention includes an accommodating portion that forms an internal space for accommodating a fluid substance and an opening that communicates with the internal space of the accommodating portion.

The lid is closely attached to the discharge port from the inside side to close the discharge port, the lid body fixed to the opening and to which the plug body is fixed, and the lid body fixed And an inner lid that is a discharge portion in which the discharge port is formed,
The inner lid includes an inner lid main body in which the discharge port is formed, and an expansion / contraction part made of an elastic body that connects the inner lid main body to the lid main body, so that the discharge port is a pressure in the lid portion. When the height is increased, the stretchable part is extended and can be moved away from the plug body, and the discharge port is biased toward the plug body by the elastic force of the stretchable part,
The stretchable part is a cylindrical bag made of a bellows-like elastic body, one opening end side is connected to the inner lid body, the other opening end side is connected to the lid body,
In a state where the discharge port is closed with a stopper, the one opening end is set at a position farther from the opening of the container body than the other opening end, and the two opening ends are The elastic force is generated by the expansion and contraction of the bellows in the direction of approaching and separating.

  Next, the invention described in claim 2 is characterized in that, with respect to the configuration described in claim 1, the surface of the inner lid main body and the distal end surface of the plug body are configured to be flush with each other.

Next, an invention described in claim 10 forms an internal space for accommodating a flowable substance inside the accommodation portion with respect to the configuration described in any one of claims 1 to 3. The inner bag is disposed, a space is formed between the inner bag, the container body, and the inner bag, and the upper space is communicated with the outside air.
Next, the invention described in claim 11 is provided in at least one of the container main body and the lid portion with respect to the configuration described in any one of claims 1 to 3 and claim 10, and externally. From the above, an air inlet having a check valve structure that allows only air to be introduced into the container body is provided.

[First Embodiment]
FIG. 1 is a cross-sectional view of a fluid substance storage container according to this embodiment as viewed from the front. 2 is a cross-sectional view as seen from the direction of arrows II-II in FIG. FIG. 3 is a plan view for explaining the outlet.
(Constitution)
First, the configuration of the fluid substance storage container will be described.

The fluid substance storage container is a tube-shaped container, and includes a tube-shaped container body 3, a lid portion 2, and an outer lid 1. The container body 3 includes an accommodating portion 3a and an opening portion 3b which are made of a flexible material and have flexibility. The opening 3b does not need to have flexibility and may have high rigidity.
The accommodating portion 3a is formed in a bag shape that forms a sealed internal space. A fluid substance 11 such as liquid or jelly is contained in the internal space in a filled state. The opening 3b is provided at one end of the housing 3a and communicates with an internal space formed by the housing 3a. The opening 3b of the present embodiment has a cylindrical shape, and a male screw is formed on the outer diameter surface.

  A lid 2 is attached to the opening 3 b of the container body 3. The lid portion 2 includes an inner cylinder portion 2a and an outer cylinder portion 2b that are concentrically disposed, and a disc portion 30 that closes one end side (extraction side of the fluid substance 11) of the inner cylinder portion 2a and the outer cylinder portion 2b. It consists of. The lid 2 is formed by integrally molding the inner cylinder 2a, the outer cylinder 2b, and the disk 30. An internal thread is formed on the inner diameter surface of the inner cylinder portion 2a, and the inner cylinder portion 2a is fixed by being screwed into the opening 3b. Reference numeral 8 denotes a screwing portion. Accordingly, the lid 2 is detachably fixed to the opening 3 b of the container body 3, and the opening of the opening 3 b is closed by the opening 3 b and the disc part 30 of the lid 2. In addition, in the state which attached the cover part 2, the other end part of the outer cylinder part 2b will be in the state contact | abutted to the accommodating part 3a. This outer cylinder part 2b is not necessarily required.

An outlet 4 for taking out the fluid substance 11 in the accommodating portion 3a is formed at a portion of the disc portion 30 of the lid portion 2 that closes one end portion of the inner cylindrical portion 2a. The outlet 4 of the lid part 2 has a certain length on the left and right when viewed from the front view of FIG. 1, but in FIG. It spreads in the shape of the end with curved surface 6. In addition, the front-end | tip part of the plate-shaped part 32 is gradually thin toward the front-end | tip.
The outlet 4 will be described.

  That is, the outlet 4 has a linear slit 31 formed in the center of the disc portion 30 in plan view, and the slit 31 portion is stretch-formed in the direction in which the fluid substance 11 is taken out. The fluid substance 11 has a shape that is pushed up in the direction of taking out the fluid substance 11. Specifically, the disc part 30 is provided with a pair of plate-like parts 32 with the slit 31 interposed therebetween, and the pair of plate-like parts 32 respectively protrudes inward in the direction of taking out the fluid substance 11. The slit 31 is formed by protruding with a curved surface and approaching each other in the direction of taking out the fluid substance 11 and contacting at the tip. In other words, the pair of plate-like portions 32 squeeze up toward each other in the direction in which the fluid substance 11 is taken out, and are in contact with each other on the tip side forming the slit 31. As a result, each plate-like portion 32 forms the curved surface 6, and the pair of plate-like portions 32 are divergent as shown in FIG. 2. Of the pair of plate portions, only one plate portion may have a curved surface convex inward, and the other plate portion may protrude in a flat plate state or the like. However, it has a wedge shape.

  Here, the left and right end portions of the pair of plate-like portions 32 are continuous as shown in FIG. 1, and only the position of the slit 31 is separated, that is, the slit 31 is the outlet 4 main body. Further, the lid portion 2, particularly the disc portion 30, is made of a plastic material having a predetermined elasticity, and the pair of plate-like portions 32 is formed by a holding force that holds the shape of the plate-like portion 32 that is pushed up. At the normal time, the tip is in close contact and sealed, and when the fluid substance 11 is taken out of the contents, the slit 31 as the tip is opened by the pushing force of the fluid substance 11 from the inside. The The pair of plate-like portions 32 may have an elastic force that urges the slits 31 in the direction in which the slits 31 are closed.

In addition, although the linear slit 31 which comprises the said exit 4 main body has illustrated the case where it extends in a straight line shape in planar view in FIG. 3, linear shape in which one part or all extends in curve shape in planar view It may be a slit.
The outer lid 1 serves as a cap that is detachably attached to the lid portion 2.
Here, the outer lid 1 can be attached to the connecting portion (the outer edge portion of the disc portion 30) between the outer cylinder portion 2b and the disc portion 30 in the lid portion 2 by fitting along the circumferential direction. A step is formed.

The outer lid 1 has a bottomed cylindrical shape that can cover the outlet 4. On the inner surface side of the outer lid 1, there is a groove or projection 5 having a shape facing the outlet 4 of the lid 2. That is, the groove | channel or projection part 5 for hold | maintaining the front-end | tip parts of a pair of said plate-shaped part 32 in contact with the inner side of the outer cover 1 which covers the said exit 4 is provided. Specifically, the groove or protrusion 5 includes two wall portions that come into contact with the outer surfaces of the distal ends of the pair of plate-like portions 32, and the pair of plate-like portions 32 is interposed between the two wall portions. The tip is sandwiched. As a result, when the outer lid 1 is mounted, the outer lid 1 restrains the slit 31 from being closed.
(Function and effect)
4A to 4C are drawings in which the opening 3b side of FIG. 2 (portion surrounded by a circular dotted line portion) is extracted and the operation thereof is described.

FIG. 4A shows the outer lid 1 removed from the lid portion 2, but the hermetic seal 12 is in an unopened state. And when using a fluid substance storage container, after removing the cover part 2 once and peeling a sealing seal, the cover part 2 is attached to the opening part 3b.
FIG. 4B shows a state in which pressure is applied to the accommodating portion 3 a in order to take out the fluid substance 11. The flowable substance 11 to which pressure is applied pushes the outlet 4 and is pushed out. That is, the fluid 4 in the container body 3 is moved to the outlet 4 side by the pressure applied to the accommodating portion 3a, so that the outlet 4 is pressurized from the inside to the outside. The pressure from the inside separates the pair of plate-like portions 32, opens the linear slit 31, and the fluid substance 11 is pushed out from the outlet 4.

FIG. 4C shows a state in which the removal pressure applied to the storage portion 3a is removed. When the pressure is removed, the slit 31 expanded by the pressure of the fluid substance 11 automatically returns to its original shape by its own restoring force, and the slit 31 comes into close contact again and is sealed. That is, as the pressure applied to the inner surfaces of the pair of plate-like portions 32 decreases, the tip portions of the pair of plate-like portions 32 come close to each other and come into contact with each other.
As described above, when the pressure applied to the accommodating portion 3a is removed, the opening made of the slit 31 is closed and the sealed portion returns to the closed state, so that the fluid substance 11 once outside flows back into the lid portion 2. And the outside air does not flow into the lid 2 and the container.

When the periphery of the outlet 4 is cleaned after the fluid substance 11 is taken out, the outlet 4 is hermetically sealed, so that the remaining fluid substance 11 and impurities do not have to worry about entering the lid 2 and the container body 3 and can be easily operated. Accordingly, the outer surface side of the lid portion 2 can always be kept clean.
Here, in the present embodiment, a pair of plate-like portions 32 squeezed toward the slit 31 forming the outlet 4 main body, that is, the pair of plate-like portions 32 gradually approach toward the slit 31. Each of the plate-like portions 32 has a substantially chevron shape having a curved surface convex inward. For this reason, the slit 31 opens with the pressure in the direction of taking out the fluid substance 11, but closes with respect to the pressure in the direction of taking in the fluid substance 11. In addition, in spite of such an effect, the linear slit 31 portion formed in the disk portion 30 has a shape that is pulled out, so that the molding is also a simple structure.

In addition, it is preferable that the pair of plate-like portions 32 have an urging force between the tips of the pair of plate-like portions 32 in the close contact direction. In the present embodiment, the plate-like portion 32 has a substantially chevron shape with a convex curved surface on the inside, so that the urging force is easily generated.
Further, at the time of subsequent storage, as shown in FIG. 2, the groove or protrusion 5 inside the outer lid 1 is pressed in the direction in which the tip of the outlet 4 is in close contact, so that the sealed state can be maintained more reliably.
[Second Embodiment]
Next, a second embodiment will be described with reference to the drawings. The same components as those in the first embodiment will be described with the same reference numerals.
(Constitution)
The basic configuration of this embodiment is the same as that of the first embodiment. However, as shown in FIG. 5, the difference is that an air introduction port 9 having a check valve structure that allows only the introduction of air into the container from the outside is provided to the lid portion 2. That is, in addition to the structure of FIG. 2, an air inlet 9 for taking outside air into the container is provided in the lid 2.

The structure will be described with reference to FIG.
As shown in FIG. 5, one or more outer air holes 10 are provided in the outer cylinder portion 2 b of the lid portion 2. When outside air is taken into the space between the outer cylinder portion 2b and the inner cylinder portion 2a from the contact portion between the other end portion (the end portion on the accommodation portion 3a side) of the outer cylinder portion 2b and the accommodation portion 3a. The outer air hole 10 is not always necessary.
Then, one or more air inlets 9 are formed in the inner cylinder portion 2 a of the lid portion 2. The air inlet 9 has a wedge shape opposite to the shape of the outlet 4. That is, since it has a wedge shape that narrows toward the inside of the cylindrical portion, the air inlet 9 is closed when pressure is applied to the housing portion 3a, and the inside of the housing portion 3a becomes negative pressure. It becomes possible to introduce inside. That is, the air inlet 9 has a check valve structure that allows only the introduction of air from the outside into the container.

In addition, you may provide the said air inlet 9 in the accommodating part 3a.
Other configurations are the same as those in the first embodiment.
(Function and effect)
FIG. 5A shows an unopened state.
FIG. 5B shows a state in which pressure is applied to the container main body 3 by removing the hermetic seal 12 and grasping the accommodating portion 3 a by hand to take out the fluid substance 11. The flowable substance 11 to which pressure is applied pushes the outlet 4 and is pushed out. At this time, the fluid substance 11 is pushed out from the outlet 4, but the air inlet 9 is closed and does not exit from the air inlet 9.

FIG. 5C shows a state immediately after the pressure for taking out the container is removed. The outlet 4 swelled by the pressure of the fluid substance 11 automatically returns to its original shape by the removal of the pressure and is in close contact and sealed.
FIG. 5 (d) shows that the outside air having the same volume as the flowable substance 11 taken out through the air inlet 9 and the outer air hole 10 due to the negative pressure in the container generated when the main body container tried to return to its original shape. The outside air 16 is taken in, and the shape of the container body 3 returns to the original shape.

Here, in the first embodiment, when the fluid substance 11 is taken out, the container body 3 remains deformed by the taken-out volume. In order to maintain the original shape of the container body 3 even after the flowable substance 11 is taken out, it is necessary to take outside air into the container. In this 2nd Embodiment, since outside air is taken in from the air introduction port 9, there exists an effect similar to 1st Embodiment except that outside air contacts the fluid substance 11 in a container. That is, the second embodiment is effective in the case where the fluid material 11 to be stored has a property that does not change even when it comes into contact with the outside air. In addition, the agent which improves air, such as a desiccant, may be arrange | positioned in the space between the outer cylinder part 2b and the inner cylinder part 2a, and the external air introduced into the container main body 3 may be improved.
[Third Embodiment]
Next, a third embodiment will be described with reference to the drawings. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and demonstrated.
(Constitution)
The basic configuration of this embodiment is the same as that of the first embodiment.

However, in this embodiment, as shown in FIG. 6, the inner bag 14 in which the inner space for accommodating the fluid substance 11 is formed is disposed inside the accommodating portion 3a, and the inner bag 14 and the container are arranged. A space 15 was formed between the main body 3 and the main body 3. Moreover, the air hole 13 for communicating the space part 15 with external air was formed in the accommodating part 3a. That is, a double structure is adopted for the accommodating portion 3a.
Other configurations are the same as those in the first embodiment.
(Function and effect)
The third embodiment will be described in comparison with the second embodiment.

When the removal pressure is removed from the container after the flowable substance 11 is taken out, the inner bag 14 remains deformed by the same volume as the volume of the taken out flowable substance 11. In 2nd Embodiment, it returns to the original shape by introduce | transducing external air from the air inlet 9. FIG. On the other hand, in the third embodiment, the shape of the housing portion 3a that forms the outer shape of the container body 3 is such that the outside air flows into the space 15 between the inner bag 14 and the housing portion 3a through the air holes 13. Return to its original form.
And in the said 2nd Embodiment, although external air will contact the fluid substance 11 in a container, in 3rd Embodiment, it can avoid that external air contacts the fluid substance 11 in a container. Therefore, the third embodiment is effective in the case where the fluid substance 11 that is desired to avoid contact with air is stored, and when the shape of the container body 3 is to be returned to the original shape after the fluid substance 11 is taken out. .
[Fourth Embodiment]
Next, a fourth embodiment will be described with reference to the drawings. In addition, about the structure similar to said each embodiment, the same code | symbol is attached | subjected and demonstrated.

FIG. 7 is a cross-sectional view for explaining the present embodiment. FIG. 8 is a plan view seen from the outlet 4 side. That is, FIG. 8 shows a part of the outlet 4 tip portion that is made thinner. 6 and 7, hatched lines 18 indicate portions where the thickness is reduced.
(Constitution)
The basic configuration of this embodiment is the same as that of the first embodiment. However, the difference is that the thickness of a part of the tip of the outlet 4 is reduced. That is, a part of the thickness along the slit 31 is relatively thinned on the tip end side of the pair of plate-like portions 32 constituting the outlet 4. In the present embodiment, as shown in FIGS. 6 and 7, the thickness in the vicinity of the center portion of the slit 31 is reduced.

As a result, when the fluid substance 11 is pressed from the inside, the portion with the reduced thickness is likely to open first.
(Function and effect)
FIG. 7A and FIG. 8A are diagrams before the take-out pressure is applied. That is, the outlet 4 is closed.
And when taking out the fluid substance 11, when the pressure is slowly applied to the accommodating portion 3a, as shown in FIGS. 7B and 8B, the sealing force of the portion 18 where the thickness of the outlet 4 is reduced is shown. It is possible to extrude the fluid substance 11 little by little from the weak part.

On the other hand, when the pressure is applied quickly, as shown in FIGS. 7 (c) and 8 (c), the entire outlet 4 is pushed and a large amount can be taken out quickly.
As described above, it is possible to provide an effective shape of the outlet 4 when it is desired to add an amount to the amount of the fluid substance 11 to be taken out.
Note that the air inlet 9 described in the second embodiment may be provided separately.
[Fifth Embodiment]
Next, a fifth embodiment will be described with reference to the drawings.
(Constitution)
The basic configuration of this embodiment is the same as that of the above embodiment. However, as shown in FIG. 9, the tip is made longer from the container side toward the outlet 4 than in the case of FIG. 1 shown in the first embodiment.

That is, the tip portions of the pair of plate-like portions 32 constituting the outlet 4 are brought into surface contact, and the length of the contact portions is set longer toward the direction of taking out the fluid substance 11. The length of the contact portion is set to 10 mm or more, for example. At the contact portion position, it is preferable that the thickness of the pair of plate-like portions 32 is made thinner than the other portions. This is to facilitate opening when the fluid substance 11 is taken out.
Here, FIG. 9A is a sectional view seen from the front, and FIG. 9B and FIG. 9C are sectional views seen from the side.
(Function and effect)
By bringing the tips of the pair of plate-like portions 32 constituting the outlet 4 into surface contact, the sealing performance is improved.

If the fluid substance 11 is altered and hardened at the tip of the outlet 4 while the fluid substance 11 is taken out several times, an appropriate amount of the tip is cut off as shown in FIG. 9C. This makes it possible to restore the function. A broken line 20 in FIG. 9 indicates a cutting position.
As described above, the fifth embodiment is effective when the fluid material 11 to be stored is a material that is easily dried and cured.
[Sixth Embodiment]
Next, a sixth embodiment will be described with reference to the drawings. In addition, about the structure similar to said each embodiment, the same code | symbol is attached | subjected and demonstrated.

The basic configuration of this embodiment is the same as that of each of the above embodiments. However, as shown in FIG. 10, the tip of the outlet 4 was corrugated.
Thereby, when taking out the fluid substance 11, a decoration mold can be attached to the surface of the fluid substance 11.
This sixth embodiment is effective when decorating foods such as mayonnaise, butter, cream, and chocolate.
[Seventh Embodiment]
Next, a seventh embodiment will be described with reference to the drawings. In addition, about the structure similar to said each embodiment, the same code | symbol is attached | subjected and demonstrated.

The basic configuration of this embodiment is the same as that of each of the above embodiments. However, as shown in FIG. 11, the stopper 17 which can contact | abut to the inner surface of a pair of plate-shaped part 32 from the said opening part 3b side was provided in the normal state. The normal state refers to a state in which no pressure is applied to the accommodating portion 3a.
In FIG. 11, the rod-shaped stopper 17 is arrange | positioned in parallel with the said slit 31, and the both ends are being fixed to the inner cylinder part 2a. The cross section of the stopper 17 is not limited to a circle. The shape which increases a contact surface with a pair of plate-shaped part 32 inner surface may be sufficient.
(Function and effect)

The outer shape of the outlet 4 is simple, and cleaning after the flowable substance 11 is taken out is easy. The present embodiment is suitable for a case where the amount taken out once is large, for example, when the flowable substance 11 is transferred to a palm, a vessel or the like.
[Ninth Embodiment]
Next, a ninth embodiment will be described with reference to the drawings. In addition, about the structure similar to said each embodiment, the same code | symbol is attached | subjected and demonstrated.
(Constitution)
14 and 15 are diagrams showing the configuration of this embodiment.

The basic configuration of this embodiment is the same as that of each of the above embodiments. However, the point which provided the pump mechanism 40 with respect to the cover part 2 differs.
In the present embodiment, the pump mechanism 40 is interposed between the inner cylinder portion 2a and the disc portion 30 in which the outlet 4 is formed. The pump mechanism 40 includes a cylindrical body part 41, a check valve 42, and a pressurizing part 45.
That is, the cylindrical body portion 41 has one end communicating with the inner cylindrical portion 2a and the other end portion closed by the disk portion 30. A check valve 42 is disposed between the inner cylinder part 2 a and the cylinder part 41. The check valve 42 is opened toward the inside of the cylinder part 41 by the pressure applied from the inner cylinder part 2a side to the cylinder body part 41 side, and is closed by the pressure applied from the cylinder body part 41 side to the inner cylinder part 2a side.

A pressurizing part 45 is provided on the side surface of the cylindrical part 41. The pressurizing part 45 includes a bellows-like elastic part 43 projecting from the side surface of the cylindrical part 41 in the outer diameter direction, and a push button 44 provided at the tip of the elastic part 43 and having higher rigidity than the elastic part 43. It consists of. The elastic portion 43 protrudes from the side surface of the cylindrical portion 41 in the outer diameter direction by its own elasticity.
(Function and effect)
By providing the cylindrical part 41, a certain volume of the fluid substance 11 can be accommodated in the cylindrical part 41. In this state, the push button 44 is pushed with a finger or the like. In other words, the push button 44 is pushed into the cylinder body 41 against the elastic force of the elastic part 43, thereby applying pressure in the cylinder body 41. This pressure closes the check valve 42 and pushes the fluid substance 11 in the cylindrical body portion 41 from the outlet 4. Further, when the push applied to the push button 44 is released, the push button 44 returns to the original position by the elastic force of the elastic portion 43 and the inside of the cylinder portion 41 becomes negative pressure and the check valve 42 opens. The fluid substance 11 in the container body 3 moves into the cylindrical body 41.

As described above, in this embodiment, when the fluid substance 11 is taken out, it is not necessary to apply pressure to the container body 3 to deform the container body 3. For this reason, the container body 3 may not be flexible. For example, the container body 3 can be made of hard glass or metal.
Here, the case where the pressurizing part 45 is provided in the cylindrical part 41 was illustrated in the said description. Instead of providing the pressurizing part 45 on a part of the side surface of the cylindrical part 41, the entire side wall of the cylindrical part 41 may be made of an elastic body. In this case, the above-described pump action is exhibited by pushing and releasing the cylinder body 41 itself.

Alternatively, as shown in FIG. 16, a balloon part 48 made of an elastic body communicating with the inside of the cylinder part 41 may be provided with respect to the cylinder part 41. In this case, the balloon part 48 is crushed, the fluid substance 11 is taken out from the outlet, and the pressure on the balloon part 48 is released, whereby the fluid substance 11 is taken into the cylindrical part 41.
[Tenth embodiment]
Next, a tenth embodiment will be described with reference to the drawings. In addition, about the structure similar to said each embodiment, the same code | symbol is attached | subjected and demonstrated.

FIG. 17 is a cross-sectional view of the fluid substance storage container according to the present embodiment as viewed from the front. 18 is a cross-sectional view taken along the line II-II in FIG.
(Constitution)
First, the configuration of the fluid substance storage container will be described.
The fluid substance storage container is a tube-shaped container, and includes a tube-shaped container body 3, a lid portion 2, and an outer lid 1. The container body 3 includes an accommodating portion 3a and an opening portion 3b which are made of a flexible material and have flexibility. The opening 3b does not need to have flexibility and may have high rigidity.

The accommodating portion 3a is formed in a bag shape that forms a sealed internal space. A fluid substance 11 such as liquid or jelly is contained in the internal space in a filled state. The opening 3b is provided at one end of the housing 3a and communicates with an internal space formed by the housing 3a. The opening 3b of the present embodiment has a cylindrical shape, and a male screw is formed on the outer diameter surface.
A lid 2 is attached to the opening 3 b of the container body 3. The lid 2 includes a lid main body 60 that is fixed to the opening 3 b and an inner lid 61 that constitutes a discharge portion fixed to the lid main body 60. The plug body 52 is fixed to the lid body 60.

The lid part main body 60 includes an inner cylinder part 2a and an outer cylinder part 2b arranged concentrically. Further, the lid main body 60 closes an annular portion between the inner cylinder portion 2a and the outer cylinder portion 2b on one end side (extraction side of the fluid substance 11) of the inner cylinder portion 2a and the outer cylinder portion 2b. An annular plate 50 is provided.
An internal thread is formed on the inner diameter surface of the inner cylinder portion 2a, and the inner cylinder portion 2a is fixed by being screwed into the opening 3b. As a result, the lid 2 is detachably fixed to the opening 3 b of the container body 3.

A plug body 52 is fixed to the annular plate 50 via a plate-like support body 51 as shown in FIGS. The plug body 52 includes a cylindrical portion and a plug body that is continuous with the cylindrical portion. The plug body has a truncated cone shape.
The inner lid 61 includes an inner lid main body 54 in which a discharge port 53 is formed, and an extendable portion 55 that connects the inner lid main body 54 and the annular plate 50. As shown in FIGS. 17, 18, and 19 (b), a discharge port 53 having an opening having the same shape as the plug body is opened at the center of the inner lid body 54. The stretchable portion 55 is a bag made of an accordion-like elastic body. That is, the expansion / contraction part 55 is thin and corrugated, spring-like, and has expansion / contraction force (elastic force). The extendable portion 55 is arranged coaxially with the inner cylinder portion 2 a and connects one end portion to the entire outer edge of the inner lid body 54 and connects the other end portion to the annular plate 50.
(Operation, action, etc.)
With the above configuration, the lid portion 2 communicates with the opening 3b of the container body 3 and is closed except for the position of the discharge port 53 by the inner cylinder portion 2a, the annular plate 50, the expansion / contraction portion 55, and the lid portion 2. Form a space. In addition, the discharge port 53 is pressed against the plug body 52 by the elastic force of the expansion / contraction part 55, so that the discharge port 53 and the plug body 52 are in close contact with each other and are closed.

On the other hand, when taking out the fluid substance 11 in the stored item, if pressure is applied to the container body 3, the internal pressure of the lid portion 2 increases due to the movement of the fluid substance 11, and the inner lid body 54 moves away from the plug body 52. In response to the elastic force of the expansion / contraction part 55, the discharge port 53 is opened, and the fluid substance 11 is taken out. Further, when the pressure is removed, the original shape returns to close contact and a closed state is obtained.
FIGS. 20 to 21 illustrate the operation of the cover 2 shown in FIG. 17 (part surrounded by a circular dotted line).

20 (a) and 20 (b) are cross-sectional views showing the discharge port 53 in a normal state in a closed state. As shown in these drawings, in the normal state, the plug body 52 is in close contact with the discharge port 53 by the elastic force of the expansion / contraction part 55 and is in a closed state.
FIGS. 21A and 21B show a state in which pressure is applied to the container body 3 in order to take out the fluid substance 11. When the inner lid 61 applies pressure to the container body 3, the fluid substance 11 in the container body 3 moves to the discharge port 53 side and the inner lid body 54 moves to the upper side in FIG. 20 due to the pressure. The discharge port 53 is opened and the fluid substance 11 is pushed out. When the pressure is removed, the inner lid 61 returns to its original shape (the state shown in FIG. 20), the plug body 52 comes into close contact with the discharge port 53, and the discharge port 53 is closed.

  As described above, the backflow of the flowable substance 11 once outside and the outside air do not flow into the lid 2 and the container. When the periphery of the outlet is cleaned after the fluid material 11 is taken out, the discharge port 53 is hermetically sealed, so there is no concern about the remaining fluid material 11 and dirt entering the cap and the container. Therefore, it is easy to work and can always be kept clean. For example, in the case of a water-soluble container such as toothpaste, even if the container is immersed in water and cleaned, there is no concern that water will enter the cap and the container. Further, at the time of subsequent storage, as shown in FIG. 1, the protrusion inside the outer lid 1 presses the inner lid 61 so that a completely sealed state can be maintained.

Further, if the surface of the inner lid main body 54 and the surface of the plug body 52 are formed to be flat when the pressure is removed in a normal state, that is, the surface of the inner lid body 54 and the distal end surface of the plug body 52 are flush with each other in the normal state. This configuration is optimal when the fluid substance 11 is transferred to a fingertip, glass rod, spoon, chopsticks, brush, or the like.
[Eleventh embodiment]
Next, an eleventh embodiment will be described with reference to the drawings. In addition, about the structure similar to said each embodiment, the same code | symbol is attached | subjected and demonstrated.
(Constitution)
The basic configuration of this embodiment is the same as that of the tenth embodiment. However, the point which provided the air inlet 9 which consists of a non-return valve structure differs like 2nd Embodiment. That is, as shown in FIG. 22, the lid 2 is provided with an air inlet 9 having a check valve structure that allows only the introduction of air from the outside into the container. That is, in addition to the structure shown in FIGS. 17 and 18, an air inlet 9 for taking outside air into the container is provided in the lid 2.

The structure will be described with reference to FIG.
As shown in FIG. 22, one or more outer air holes 10 are provided in the outer cylinder portion 2 b of the lid portion 2. When outside air is taken into the space between the outer cylinder portion 2b and the inner cylinder portion 2a from the contact portion between the other end portion (the end portion on the accommodation portion 3a side) of the outer cylinder portion 2b and the accommodation portion 3a. The outer air hole 10 is not always necessary.
Then, one or more air inlets 9 are formed on the annular plate 50 of the lid 2. Since the air introduction port 9 has a wedge shape that narrows toward the inside of the lid body, the air introduction port 9 is closed when pressure is applied to the housing portion 3a, and the inside of the housing portion 3a becomes negative pressure. This makes it possible to introduce outside air into the inside. That is, the air inlet 9 has a check valve structure that allows only the introduction of air from the outside into the container.

In addition, you may provide the said air inlet 9 in the accommodating part 3a.
Other configurations are the same as those in the tenth embodiment.
(Function and effect)
When a pressure is applied to the container body 3 by, for example, grasping the storage portion 3a by hand to take out the fluid material 11, the inner lid against the elastic force of the expansion / contraction portion 55 is applied by the fluid material 11 under pressure. When the main body 54 moves in a direction away from the plug body 52, the discharge port 53 opens and the fluid substance 11 is pushed out. At this time, the fluid substance 11 is pushed out from the discharge port 53, but the air introduction port 9 is closed and does not exit from the air introduction port 9.

FIG. 22 (a) shows a state immediately after removing the pressure for removal from the container. At this time, the discharge port 53 opened by the pressure of the fluid substance 11 is automatically closely attached and sealed by removing the pressure.
Next, as shown in FIG. 22 (b), due to the negative pressure in the container that is generated when the main body container tries to return to its original shape, the outside air having the same volume as the flowable substance 11 taken out becomes the air inlet 9 and The outside air 16 is taken into the container through the outer air hole 10, and the shape of the container body 3 returns to the original shape.

Here, in the tenth embodiment, when the fluid substance 11 is taken out, the container main body 3 remains deformed by the taken-out volume. In order to maintain the original shape of the container body 3 even after the flowable substance 11 is taken out, it is necessary to take outside air into the container. In the eleventh embodiment, since the outside air is taken in from the air inlet 9, the same effect as in the first embodiment is obtained except that the outside air contacts the fluid substance 11 in the container. That is, the second embodiment is effective in the case where the fluid material 11 to be stored has a property that does not change even when it comes into contact with the outside air. In addition, the agent which improves air, such as a desiccant, may be arrange | positioned in the space between the outer cylinder part 2b and the inner cylinder part 2a, and the external air introduced into the container main body 3 may be improved.
[Twelfth embodiment]
Next, a twelfth embodiment will be described with reference to the drawings. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and demonstrated.
(Constitution)
The basic configuration of this embodiment is the same as that of the tenth embodiment. However, as in the third embodiment, a double structure is adopted as the accommodating portion 3a. That is, as shown in FIG. 23, an inner bag 14 having an internal space for accommodating the flowable substance 11 is disposed inside the accommodating portion 3a, and the inner bag 14 and the container body 3 are disposed between the inner bag 14 and the container main body 3. The space part 15 was formed in. Moreover, the air hole 13 for communicating the space part 15 with external air was formed in the accommodating part 3a. That is, a double structure is adopted for the accommodating portion 3a.

Other configurations are the same as those in the tenth embodiment.
(Function and effect)
The third embodiment will be described in comparison with the above eleventh embodiment.
When the removal pressure is removed from the container after the flowable substance 11 is taken out, the inner bag 14 remains deformed by the same volume as the volume of the taken out flowable substance 11. In the eleventh embodiment, the air is returned to the original shape by introducing outside air from the air inlet 9. On the other hand, in the twelfth embodiment, the outside air flows into the space portion 15 between the inner bag 14 and the housing portion 3a through the air hole 13, so that the shape of the housing portion 3a that forms the outer shape of the container body 3 is Return to its original form.

And in the said 2nd Embodiment, although external air will contact the fluid substance 11 in a container, in 3rd Embodiment, it can avoid that external air contacts the fluid substance 11 in a container. Therefore, the third embodiment is effective in the case where the fluid substance 11 that is desired to avoid contact with air is stored, and when the shape of the container body 3 is to be returned to the original shape after the fluid substance 11 is taken out. .
[Thirteenth embodiment]
Next, a thirteenth embodiment will be described with reference to the drawings. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and demonstrated.
(Constitution)
The basic configuration of this embodiment is the same as that of the tenth embodiment. However, as shown in FIG. 24, the difference is that the discharge portion protrudes in the direction of taking out the fluid substance 11 so that the discharge port 53 is tubular or conical.

That is, as shown in FIG. 24, the inner lid body 54 protrudes in a cylindrical shape from the container side toward the outlet. At the same time, the plug body 52 is also projected by the length of the discharge port 53. However, the distal end portion of the plug body 52 is in close contact with the discharge port 53. That is, the side surface of the plug body 52 and the surface of the discharge port 53 have a gap other than the tip of the plug body 52. This is because the inner lid body 54 is easy to move with respect to the plug body 52.
That is, at least the distal end portion of the discharge port 53 and the distal end portion of the plug body 52 constitute the discharge port 53 and the plug body 52 referred to in the claims.
(Function and effect)
In this embodiment, it becomes a convenient shape when the fluid substance 11 is directly transferred from the discharge port 53 to a target place. In addition, you may attach | subject a decorative tool, such as a waveform, to the surface of the fluid substance 11 at the exit tip, or attach an auxiliary tool for handling delicate work.
[Fourteenth embodiment]
Next, a fourteenth embodiment will be described with reference to the drawings. In addition, about the structure similar to the said embodiment, the same code | symbol is attached | subjected and demonstrated.

25 and 26 are diagrams showing the configuration of this embodiment.
(Constitution)
The basic configuration of this embodiment is the same as that of each of the above embodiments. However, the point which provided the pump mechanism 40 with respect to the cover part 2 differs like 9th Embodiment.
In the present embodiment, the pump mechanism 40 is interposed between the inner cylinder portion 2a and the inner lid 61 in which the outlet 4 is formed. The pump mechanism 40 includes a cylindrical body part 41, a check valve 42, and a pressurizing part 45.

That is, one end portion of the cylindrical portion 41 communicates with the inner cylindrical portion 2a, and the other end portion is closed by the inner lid 61. A check valve 42 is disposed between the inner cylinder part 2 a and the cylinder part 41. The check valve 42 is opened toward the inside of the cylinder part 41 by the pressure applied from the inner cylinder part 2a side to the cylinder body part 41 side, and is closed by the pressure applied from the cylinder body part 41 side to the inner cylinder part 2a side.
A pressurizing part 45 is provided on the side surface of the cylindrical part 41. The pressing part 45 includes an elastic part 43 projecting from the side surface of the cylindrical part 41 in the outer diameter direction, and a push button 44 provided at the distal end of the elastic part 43 and having higher rigidity than the elastic part 43. . The elastic portion 43 protrudes from the side surface of the cylindrical portion 41 in the outer diameter direction by its own elasticity.
(Function and effect)
By providing the cylindrical part 41, a certain volume of the fluid substance 11 can be accommodated in the cylindrical part 41. In this state, the push button 44 is pushed with a finger or the like. That is, the push button 44 is pushed into the cylinder body 41 against the elasticity of the elastic part 43, thereby applying pressure in the cylinder body 41. This pressure closes the check valve 42 and pushes the fluid substance 11 in the cylindrical body portion 41 from the outlet 4. Further, when the push applied to the push button 44 is released, the push button 44 returns to the original position by the elastic force of the elastic portion 43 and the inside of the cylinder portion 41 becomes negative pressure and the check valve 42 opens. The fluid substance 11 in the container body 3 moves into the cylindrical body 41.

As described above, in this embodiment, when the fluid substance 11 is taken out, it is not necessary to apply pressure to the container body 3 to deform the container body 3. For this reason, the container body 3 may not be flexible. For example, the container body 3 can be made of hard glass or metal.
Here, the case where the pressurizing part 45 is provided in the cylindrical part 41 was illustrated in the said description. Instead of providing the pressurizing part 45 on a part of the side surface of the cylindrical part 41, the side wall of the cylindrical part 41 may be formed of an elastic body. In this case, the above-described pump action is exhibited by pushing and releasing the cylinder body 41 itself.

Or you may provide the balloon part 48 which consists of an elastic body connected to the inside of a cylinder with respect to the cylinder part 41 like FIG. In this case, the balloon part 48 is crushed, the fluid substance 11 is taken out from the outlet, and the pressure on the balloon part 48 is released, whereby the fluid substance 11 is taken into the cylindrical part 41.
(Modification)
Here, in the tenth embodiment to the fourteenth embodiment, the surface of the inner lid main body 54 may be formed as a concave surface, and the stored items may be temporarily stored in the concave portion so that the color, fragrance, capacity, etc. can be confirmed. . You may make it measure easily the volume at the time of taking out stored goods, such as marking a scale on the surface of a recessed part. Further, the surface of the inner lid 61 may have various shapes depending on purposes such as a spherical convex shape.

Here, in all the above-described embodiments, the outer lid 1 is illustrated as being attached by fitting as shown in the joint portion 7 of the lid main body 60, but is not limited thereto. It may be a hinged or screwed type.
Moreover, the case where the cover part 2 and the opening part 3b of the container main body 3 are attached by screwing type screwing is illustrated. However, in the case where the hermetic seal 12 is not used, a fixed connection such as a fitting type or heat fusion may be used. In this case, the opening / unopening treatment is performed at the joint portion 7 of the lid portion 2 outer lid 1 and the lid portion main body 60 or the like.

In consideration of the properties of the fluid substance 11 to be stored, various materials such as synthetic resin, synthetic fiber, and metal are selected and used as the material of the lid portion 2. Further, it may be possible to make cleaning easier by preliminarily applying a substance capable of repelling the fluid substance 11 to be stored near the outside of the outlet 4.
In this specification, the shape of the container body 3 is a tube type, but a bottle-like container such as a plastic bottle may be used.
Since the container of the present invention does not require any special technique or material in production as compared with the conventional product, it can be improved at the same cost as the conventional product.
