The objects, specific advantages and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments in conjunction with the accompanying drawings. In the present specification, in adding reference numerals to the components of each drawing, it should be noted that the same components as possible, even if displayed on different drawings have the same number as possible. In addition, in describing the present invention, if it is determined that the detailed description of the related known technology may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 8, the fluid container 1 according to the first embodiment of the present invention includes a container body 10, a pumping unit 20, a volume variant 30, and a suction pipe 40. .

The container body 10 accommodates contents. Contents contained in the container body 10 may be cosmetics, shampoo, toothpaste, etc., the type of the content is not particularly limited. However, in the present embodiment, the contents may be a material having a state capable of being sucked and discharged along at least the suction pipe 40.

The container body 10 may be provided in an open form to one side to discharge the contents, the open side may be coupled to the pumping unit 20 to be described later. Due to the combination of the pumping unit 20, the open one side of the container body 10 can maintain a closed state, the contents contained in the container body 10 is discharged to the outside only through the pumping unit (20).

Container body 10 can be made of a variety of materials, such as synthetic resin, metal, ceramics, and if there is a space to accommodate the contents there is no limitation on the material. However, at least one side of the container body 10 to which the pumping unit 20 is coupled for coupling between the container body 10 and the pumping unit 20 may be made of a material having rigidity.

The pumping unit 20 is provided on one side of the container body 10 to discharge the contents. The pumping unit 20 may be coupled to an open side of the container body 10 to seal the open side, and may include a head 21 and a cap 22.

The head 21 is a structure pressed by a user etc., and has the discharge opening 211 in one side. The discharge port 211 may simply be a hole or may be a discharge path extending in the form of a nozzle.

The head 21 may be a form in which a nozzle extending to one side is added to a portion having a relatively large area to easily receive pressure, but the shape of the head 21 is not particularly limited. In addition, although the discharge port 211 is also shown as one in the drawings, it is noted that may be a plurality as needed.

The head 21 may be provided with a stem 212 for transmitting pressure to the volume deformation body 30 to be described later through the cap 22, the stem 212 is capable of lifting up and down inside the cap 22. Can be prepared.

Cap 22 is coupled to one side of the container body (10). Cap 22 is coupled to the one side open from the container body 10 in a variety of ways, such as screw, can seal the open one side of the container body (10).

The head 21 is provided in the cap 22 so that the head 21 can be elevated. That is, the cap 22 may have a form in which the inside penetrates up and down to allow the head 21 to move up and down. In this case, the stem 212 or the suction pipe 40 of the head 21 may be positioned inside the cap 22.

A sealing unit 23 may be provided between the cap 22 and the container body 10. The sealing unit 23 may use general components for implementing a sealing function such as an O-ring or a gasket, and a sealing unit ( The position at which the 23 is provided may be between the cap 21 and the cap 22, which are lifted inside the cap 22, in addition to the cap 22 and the container body 10.

When the user presses the head 21, the stem 212 of the head 21 descends inside the cap 22 and exerts pressure on the volumetric deformation body 30 to be described later, through which the contents are transferred to the head 21. It can be discharged to the outside through the discharge port 211 of the head 21.

Then, when the user releases the head 21, the stem 212 of the head 21 is raised inside the cap 22. At this time, the rise of the stem 212 may be made by the elastic force of the volume variant 30, which will be described later.

In the related art, in order to use the pumping unit 20, a complicated structure such as a cylinder and a piston is required, so that a large number of members are required, thereby increasing the manufacturing cost and increasing the defective rate. Restoration to the original position after the pressing of the) is simply made by the volumetric deformable body 30 to be described later, and the discharge of the contents is also simply made through compression / expansion of the volumetric deformable body 30, thereby simplifying the structure and manufacturing costs. It can drastically lower and reduce the risk of manufacturing defects and breakdowns.

The volume deformation body 30 is located on the inner bottom of the container body 10, and when the pumping unit 20 is pressed, it pushes up the contents inside, and when the pumping unit 20 is released, the container body ( 10) The contents can be inhaled.

That is, the volume modifier 30 may be made of a material that can deform the volume, but may be, for example, PP, PE or the like, but is not particularly limited. In addition, the volume variant 30 may be made of a structure capable of volume deformation separately or together with the material that can be modified in volume.

The volume variant 30 may have a structure in which the bellows tube 31 and the suction tube 32 are provided up and down. Bellows tube 31 is connected to the lower end of the suction pipe 40, the upper side is inserted into the suction pipe 40.

When the head 21 is pressed, the suction pipe 40 is lowered to compress the bellows tube 31. In order to prevent the bellows tube 31 from being inserted into the suction pipe 40 instead of being compressed by the suction pipe 40, The upper periphery of the bellows tube 31 may be provided with a circular frame 312 for supporting the lower end of the suction pipe (40). Therefore, the lower end of the suction pipe 40 can compress the bellows tube 31 by pressing down the ring frame 312 of the bellows tube 31.

The bellows tube 31 is compressed when the pumping unit 20 is pressed to push up the contents of the inside, and when the pumping unit 20 is released, the bellows tube 31 is expanded and the contents of the container body 10 through the suction tube 32. May be inhaled.

To this end, the bellows tube 31 may be provided with a discharge opening 311 at an upper end thereof, and the discharge opening 311 has an elastic force that opens when the bellows tube 31 is compressed and closes when the bellows tube 31 is expanded. Can be.

The discharge openings 311 have at least two or more valves 311a closer to each other toward the upper end and in contact with each other at the upper end. For example, in the present embodiment, the discharge opening 311 may have two valves 311a facing each other, and the valves 311a may be in contact with each other at an upper end to maintain the discharge opening 311 in a sealed state. In this case, the valve 311a may be formed of a material that can be bent.

However, when the bellows tube 31 is compressed, the pressure inside the bellows tube 31 is increased, and the contents push the valve 311a in the direction in which they open. Therefore, the two valves 311a which are in contact with each other at the upper end can be opened by opening the discharge opening 311 as a gap is formed by the contents.

That is, the bellows tube 31 may be compressed when the pumping part 20 is pressed through the discharge opening 311 so that the contents thereof may move upward. The contents moved upward from the bellows tube 31 may exit the discharge port 211 through the stem 212 via the suction pipe 40.

Of course, the shape of the discharge opening 311 is not limited to the above, and the discharge opening 311 has a slit that is allowed to penetrate the contents while maintaining a closed state and opening when the internal pressure of the bellows tube 31 increases. And / or may be deformed by the increase in the internal pressure of the bellows tube 31 to have a check valve to allow the passage of the upper portion of the contents, but to block the passage of the lower portion of the contents.

The bellows tube 31 further includes a pleated portion 313 provided below the discharge opening 311 and a coupling portion 314 provided below the pleated portion 313. The wrinkles 313 may be formed in a bellows shape, and a minimum cross section of the wrinkles 313 may be larger than a cross section of the suction pipe 40. Through this, a sufficient amount of contents may be discharged to the discharge port 211 even for one-time compression of the bellows tube 31.

When the head 21 is pressed, the inner space of the bellows tube 31 is reduced while the wrinkles of the wrinkles 313 are folded, thereby increasing the internal pressure. Therefore, the contents are discharged to the pumping part 20 through the suction pipe 40 after opening the discharge opening 311 by itself.

On the contrary, when the head 21 is released, the bellows tube 31 is expanded while the wrinkles 313 are unfolded, and the inner space of the bellows tube 31 is expanded to decrease the internal pressure. Therefore, while the internal pressure of the bellows tube 31 is relatively lower than the internal pressure of the container body 10, the contents can be transferred from the interior of the container body 10 to the interior of the bellows tube 31.

When the head 21 is depressed, the expansion of the bellows tube 31 may be caused by an elastic force that the wrinkles of the wrinkles 313 are to be unfolded. That is, the pleats 313 have an elastic force that stretches up and down, and the elastic force of the pleats 313 generated when the head 21 is pressed is deformed (expanded) of the bellows tube 31 when the head 21 is released. Will be generated.

In the bellows tube 31, the thickness of the discharge opening 311 may be relatively thicker than the thickness of the corrugation portion 313. This prevents the discharge opening 311 located in the suction pipe 40 from unnecessarily rising when the suction pipe 40 is lowered by the pressing of the head 21 as described above, and maintains a constant position in the suction pipe 40. To do this.

The aforementioned annulus 312 may be disposed between the discharge opening 311 and the corrugation part 313 inserted into the suction pipe 40, and the bellows tube 31 may have the corrugation part 313 from the discharge opening 311. It may have a form that the cross section is enlarged toward). That is, even if the annulus 312 fails to block the insertion of the discharge opening 311 into the suction pipe 40, the wrinkle part (3) is formed in the suction pipe 40 due to the cross-sectional expansion between the discharge opening 311 and the wrinkle part 313. 313 can be prevented from being inserted.

The coupling part 314 is provided below the wrinkle part 313 and accommodates the suction tube 32 inside. That is, the suction tube 32 may be drawn in the lower side of the bellows tube 31. However, the coupling part 314 may be provided so as not to cover the suction port 322 provided in the suction tube 32, that is, the lower end of the bellows tube 31 may be spaced upwardly from the bottom of the container body 10. have.

The bellows tube 31 may be coupled to the suction tube 32 to surround the suction tube 32 through the coupling portion 314, and the bellows tube 31 and the suction tube (although the bellows tube 31 is under pressure). The bellows tube 31 and the suction tube 32 are provided with an annular groove 51 and an annular shape so that the lower end of the bellows tube 31 does not cover the inlet 322 of the suction tube 32. It can be engaged by the engagement of the projection (52).

Of course, unlike the above-mentioned coupling portion 314 may be provided to extend to the position parallel to the lower end of the suction tube 32, the lower end of the bellows tube 31 may be in contact with the bottom of the container body (10) have. However, in this case, the position corresponding to the suction port 322 may be formed in the coupling portion 314.

The suction tube 32 is located at the inner bottom of the container body 10 and connected to the lower end of the bellows tube 31. Unlike the bellows tube 31, the suction tube 32 may not be configured to be compressed or expanded up and down. However, the suction tube 32 may serve to deliver contents during compression / expansion of the bellows tube 31. Can be.

The suction tube 32 may have a suction opening 321 at an upper end thereof, and the suction opening 321 may have two or more valves 321a that are the same as or similar to the discharge opening 311. However, the valve 321a of the suction opening 321 may have a wider width, a lower height, and a larger slope than the valve 311a of the discharge opening 311.

The suction opening 321 may have an elastic force that is closed when the bellows tube 31 is compressed. Unlike the suction opening 321, the discharge opening 311 is opened when the bellows tube 31 is compressed. This means that the internal pressure of the bellows tube 31 causes the valve opening 311a of the discharge opening 311 to be separated from each other. This is because it acts in the opening direction, and the suction opening 321 acts in the direction in which the valves 321a of the suction opening 321 abut against each other. In contrast, the suction opening 321 may be opened when the bellows tube 31 is expanded.

The valve 321a of the suction opening 321 is inclined or curved toward the inside of the bellows tube 31, while the valve 311a of the discharge opening 311 is inclined or curved toward the outside of the bellows tube 31. Therefore, the upper side of the bellows tube 31 is opened and the lower side is closed when the bellows tube 31 is compressed, while the upper side of the bellows tube 31 is sealed and the lower side is open when the bellows tube 31 is expanded. . Therefore, by compression / expansion of the bellows tube 31, the contents can be efficiently delivered.

The upper end of the suction tube 32 may be positioned higher than the lower end of the corrugation part 313 and / or the upper end of the coupling part 314. This is to ensure an appropriate inclination angle with respect to the valve 321a of the suction opening 321.

A suction port 322 is provided below the suction tube 32 to communicate with the inside of the container body 10. At least one suction port 322 may be provided, and a plurality of suction ports 322 may be provided around the lower side of the suction tube 32.

The suction port 322 of the suction tube 32 may be provided not to be covered by the bellows tube 31, and the inside of the suction tube 32 and the inside of the container body 10 may maintain a communication state. . However, the flow of the contents, leading to the interior of the bellows tube 31 through the interior of the suction tube 32 from the container body 10 during expansion of the bellows tube 31, the suction during the compression of the bellows tube 31 As the opening 321 is blocked, the contents inside the bellows tube 31 may not flow back into the suction tube 32.

The suction pipe 40 connects the pumping part 20 and the volumetric deformation body 30. The suction pipe 40 is fixed to the bellows tube 31 so that the lower end surrounds the discharge opening 311 of the bellows tube 31 positioned at the bottom of the container body 10, and extends upwardly so that the upper end of the stem 212. It can be fixed to.

The suction tube 40 and the bellows tube 31 can be joined to each other by the same / similar configuration to the engagement of the annular groove 51 and the annular projection 52 mentioned above, so that the suction tube 40 is connected to the head 21. When the lowering is caused by the pressing of), the discharge opening 311 is not inserted into the suction pipe 40 and the compression of the bellows tube 31 can be sufficiently realized.

The suction pipe 40 and the stem 212 may be coupled by the engagement of the annular groove 51 and the annular protrusion 52, in which case the upper side of the suction pipe 40 is provided with a plurality of annular grooves 51 and up and down. And / or have an annular protrusion 52 so that at least a portion of it has a pleat shape. The cross section of the suction pipe 40 may be the same as the cross section of the stem 212, but the upper side of the suction pipe 40 may be fixed to the top so that the upper end of the suction pipe 40 may be fixed while being inserted into the stem 212. Increasing cross-section may be in the form.

The suction pipe 40 may be provided vertically and vertically. For this purpose, the stem 212 and the volume variant 30 may be disposed in parallel with their centers. The connection of the suction pipe 40 and the stem 212 may also be made by using the engagement of the annular groove 51 and the annular protrusion 52 described above and then overlapped with each other, thereby preventing leakage of the contents. Alternatively, the suction pipe 40 and the stem 212 may be provided integrally.

Hereinafter, the discharge process of the contents in the present embodiment will be described with reference to the accompanying drawings.

Referring to FIG. 7, when the suction pipe 40 descends due to the head 21 being pressed, the bellows tube 313 of the bellows tube 31 coupled to the lower end of the suction pipe 40 is compressed, thereby compressing the bellows tube 31. The internal volume will be reduced.

Therefore, the internal pressure of the bellows tube 31 is increased, and the increase in the internal pressure causes the valve 311a of the discharge opening 311 to bend to cause the discharge opening 311 to be opened. Of course, the internal pressure of the bellows tube 31 raised by the pressing of the head 21 is pressed in the direction in which the valves 321a of the suction openings 321 abut each other, so that the suction openings 321 can be kept closed. have.

That is, the lower side of the bellows tube 31 is sealed and the upper side is opened, so that the internal pressure increases, and the contents contained in the bellows tube 31 are pushed up to the suction pipe 40 through the discharge opening 311. Thus, the contents are discharged through the stem 212 to the discharge port 211.

On the contrary, referring to FIG. 8, when the head 21 is released, the bellows tube 31 expands in the direction in which the height of the bellows tube 31 increases due to the elastic force of the wrinkle part 313.

When the bellows tube 31 expands, internal pressure decreases due to an increase in internal volume, which pulls the valve 311a of the discharge opening 311 in a direction in which the bellows tube 31 abuts each other, and simultaneously pulls the valve 321a of the suction tube 32 away. It is pulled in the direction of each other.

Therefore, as the lower side of the bellows tube 31 is opened and the upper side is closed, the internal pressure decreases, and the contents contained in the container body 10 are separated from the suction port 322 and the suction opening 321 of the suction tube 32. It can be sucked into the interior of the bellows tube (31).

By repeating this process, the contents of the container body 10 can be discharged to all the discharge port 211, in particular the suction port 322 provided in the suction tube 32 and the inner bottom of the container body 10 Since arranged side by side, the present embodiment can minimize the residual amount.
