DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container having both spraying and evaporation functions. More particularly, it stores, in particular, volatile liquids, such as fragrances, deodorants, insecticides or antibacterial and antifungal agents, or mixtures thereof,
The present invention relates to a container provided with both a spraying mechanism using a pump for liquid spraying and an evaporating mechanism, and capable of spraying an appropriate amount of liquid to various places or the atmosphere as desired while constantly evaporating liquid.

[0002]

2. Description of the Related Art Conventionally, there has been known a container capable of discharging a liquid stored in a container body and also capable of spontaneous evaporation of the liquid. For example,
JP-T-Hei 6-504480 uses an elastically deformable container, a mechanism that instantaneously disperses the liquid content by holding and pressing the container body by hand, and a liquid absorbing material using the penetration phenomenon. A dispenser provided with a mechanism for performing natural transpiration is disclosed.

However, this dispenser has a complicated structure and requires two pipes, a discharge pipe for discharging the liquid and a liquid-absorbing material guide pipe for guiding the liquid to evaporate. The member becomes large, so that the whole container becomes large. Also, depending on the shape of the container main body, there is also a problem that the lower end of the liquid-absorbing material guide tube abuts the container main body, so that attention must be paid to the attachment of the inner plug member.

[0004] Therefore, a flexible sucking portion or an acrylic resin or a polyester resin manufactured by aligning and solidifying a large number of plastic filaments in a liquid absorbing rod-shaped sucking portion serving as a guide tube in the invention. Liquid aroma that uses a flexible suction part formed by solidifying the cilia made of a liquid and has a liquid-absorbing rod-shaped suction part housed in a discharge pipe to realize a simplified and compact structure. Agent container was proposed (Japanese Patent Application Nos. 6-17886 and 6-1)
No. 78893).

[0005]

However, since these conventional containers press the entire container by hand, there is a limit to the pressure that can be applied to the liquid phase by gripping and pressing, and the container body is almost full of liquid. Even when the volume of the gaseous phase is relatively small, it is difficult to disperse the gas into the air in a state like water droplets and to form a fine mist having excellent diffusion efficiency. Further, as the remaining amount of liquid in the container body decreases, the gas phase becomes larger, and it is difficult to spray unless pressed with a strong force, and the dripping fragrance may adhere to the hand. Therefore, if the material constituting the container body is made flexible so that sufficient pressure can be applied even with a weak force, the strength cannot be avoided. Further, according to the above mechanism, it is difficult to control the spray amount.

Further, the material of the container body, the necessity of a preferred form for gripping and pressing, and the like have also been factors that greatly limit the variety of container designs to meet the taste. Further, since the material of the container body having elasticity is limited, the physical properties of the liquid that can be stored in the container are necessarily limited, and the application range of the container is extremely narrow.

[0007] As described above, a liquid container having both spraying and evaporation functions, wherein a constant amount of liquid is sprayed in a mist state having excellent diffusion efficiency to the atmosphere regardless of the remaining amount of liquid. There is no proposal for a container with a variety of container designs and application areas.

[0008]

Means for Solving the Problems The present inventors have made intensive studies in view of the present situation, and as a result, in addition to the transpiration mechanism,
The inventors have found that the above problem can be solved by adopting a structure in which a liquid stored in a container body is sprayed by employing a pump mechanism with a spray nozzle, and have completed the present invention.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid container having both spraying and evaporation functions according to the present invention comprises a container body, a pump mechanism having a spray nozzle for spraying the liquid stored in the container body, and a suction device. And a transpiration mechanism configured by a diverging portion, wherein the suction portion is immersed in a liquid stored in the container body at least at a lower end portion, and extends to reach the diverging portion exposed to the outside air. The liquid guided by the suction part is evaporated from the upper surface of the diverging part into the outside air.

Further, the container of the present invention has a cap which can be fitted to a closing lid screwed on the upper part of the container body to which the spray nozzle is attached, and the cap is attached to the upper part of the container body. When fitted to the closed lid portion, a partition wall substantially in contact with the upper surface of the diverging portion constituting the evaporating mechanism is provided in the cap. Therefore, if the container rolls over when the cap is fitted,
It is possible to prevent the liquid from leaking from the diverging portion into the cap, and it is possible to prevent the content liquid from dripping when the cap is opened. In particular, this leakage prevention function is important when a liquid such as an antibacterial antifungal agent or an insecticide that is not desired to directly touch the human body is stored and used.

With the above structure, not only the control of the spray amount is facilitated, but also various container materials can be selected.
It is expected that the variety of container designs and storable liquids will be increased to broaden the application range, and that the structural and functional stability and safety of the container will also be improved.

[0012] Further, when spraying to a specific site is desired, the conventional product cannot be sprayed in a tilted manner, particularly when the residual liquid amount is reduced, and it is difficult to spray other than above the container. Although the location was limited, when the container of the present invention is used, the sprayable portion is significantly widened, so that it is used for a fragrance, a deodorant, an insecticide or an antibacterial antifungal agent, or a mixture thereof. It is advantageous. For example, spraying can be performed very easily even toward a side wall or the like near the floor where moisture easily stays.

In the container of the present invention, the evaporation can be temporarily stopped by re-fitting the cap to the closing lid at any time after the start of use, and the container can be reused without difficulty.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.

1 to 3 are longitudinal sectional views showing one embodiment of the container of the present invention. FIG. 1 shows the state when the cap is fitted.
FIG. 3 shows a state after the cap is opened, and FIG. 3 shows a state when the cap is pressed. FIG. 4 shows the state when the cap is fitted, that is, FIG.
FIG.

As described above, the present invention is directed to a liquid container 1 having both spraying and evaporating functions.
A pump mechanism having a spray nozzle 21 for spraying the liquid stored in the container body 10, and a transpiration mechanism including a suction unit 31 and a diverging unit 32.

The container body 10 may have any shape as long as the pump mechanism and the evaporating mechanism can be mounted thereon, but it is easy to grasp when pressing the head of the pump to spray the liquid, and is mounted on a floor or a shelf. It is preferable that it has a stable shape that does not easily roll over when placed.

The material of the container body 10 can be selected from a variety of materials, for example, plastic resins (olefin resins including polypropylene and polyethylene, ester resins including polyethylene terephthalate and polystyrene, vinyl resins including vinyl chloride, valex). (Registered trademark)
, An acrylic resin containing, and polymethylpentene (PMP)), glass, pottery, and the like. Considering weight, strength, compatibility with the liquid to be stored, etc., polypropylene, polyethylene, polyethylene terephthalate, Valex (registered trademark), vinyl chloride, polymethylpentene (PMP) or glass is particularly preferred. With these materials, containers of various designs and colors according to various tastes can be created.

The liquid stored in the container body 10 is
Liquids such as properties such as pH, volatility and resin solubility, and components contained in liquids (active ingredients such as fragrances, deodorants, insecticides or antibacterial agents, surfactants, solvents, etc.) A preferable body material should be selected in consideration of factors that may affect the inner wall of the container 1 due to long-term residence. Since various materials can be used for the container of the present invention, it can also be used for liquids which could not be applied in the conventional container which requires the above-mentioned flexibility.

The pump mechanism for atomizing the liquid stored in the container body 10 has a spray nozzle 21, a pump casing 24, a piston 23 for feeding liquid, a spring 22 for operating the piston, and a pump 22. A pump including a ball 25 as a check valve that shuts off the opening to the communication pipe 26 when the head is pressed is provided together with the communication pipe 26 via the closing lid 14 to the container body 10.
Is screwed on. At the time of screwing, the gasket 13 is interposed between the gasket 13 and the container body 10, so that the internal solution pushed up when the pump is pressed is prevented from leaking from the container opening.
The spray nozzle 21 has a narrow groove spirally formed in the liquid discharge portion. When the content liquid passes through the narrow groove with pressurization, the spray becomes a fine mist.

In a preferred embodiment of the present invention, the container 1 of the present invention comprises a container body 10 to which the spray nozzle is attached.
It has a cap 11 that can be fitted to the closing lid 14 screwed to the upper part, and when the cap 11 is fitted to the closing lid 14 attached to the upper part of the container main body 10, the cap 11 forms the evaporation mechanism. Divergence section
A partition wall 12 substantially in contact with the upper surface of the cap 32 is provided in the cap 11. Therefore, when the container 1 is turned over when the cap 11 is fitted, it is possible to prevent the liquid from leaking from the diverging portion 32 into the cap 11. In this embodiment, the pump mechanism may be rotatably screwed to the container body 10 via the closing lid 14.

The outline of the process of spraying the content liquid by the pump mechanism will be described below with reference to the drawings.

1) Before use, when the cap is fitted (see FIG. 1): The piston mechanism, together with the communication pipe 26 and the cap 11,
It is fitted to a closing lid 14 screwed to the container body 10.
The spring 22 in the pump is in a compressed state due to the screwing of the cap 11, and an elastic force for pushing up the cap 11 is stored. As described above, the partition wall 12 is provided in the cap 11 so as to be almost in contact with the upper surface of the divergent portion 32, and the divergent portion 32 is in a sealed state, so that when the rollover is performed in the state of FIG. Leakage into the cap 11 and subsequent opening of the cap afterwards is prevented.

2) When the cap is released and left (see FIG. 2): When the cap 11 is removed from the closing lid 14 by rotating the cap 11 together with the pump, the elastic force of the contracted spring 22 causes The piston 23, the cap 11, and the spray nozzle 21 are lifted to a predetermined position. At this time, the ball 25 serving as a check valve floats, and an amount of liquid corresponding to the increased pump internal volume is sent into the pump casing 24 from the communication pipe. Since the volume of the gas phase in the container body 10 is reduced corresponding to the volume sent into the pump casing 24, the container body 10
A slit 27 is provided in the pump casing 24 so that outside air is sucked inside.

3) When the cap is pressed (see FIG. 3): By pressing the cap 11, the ball 25 is pressed so as to close the end of the communication pipe 26, and pressure is applied to the pump casing 24 filled with liquid. . With this pressure, the liquid is pushed up from inside the piston 23 toward the spray nozzle 21. The liquid reaches the spray nozzle 21 attached to the cap 11, and is extruded through the spiral groove 28, so that the liquid can be ejected in a mist. When the cap 11 is released from the pressure, the pump mechanism returns from the pressed state to the stationary state by the elastic force of the compressed spring 22, and at this time, 2)
The liquid is sent again into the pump casing 24 as described in (1).

Another mechanism which is a feature of the liquid container 1 of the present invention is a vaporization mechanism including a suction part 31 and a diverging part 32 (see FIGS. 1 to 3). The siphoning section 31 has at least a lower end immersed in the liquid stored inside the container body 10 and extends to reach the diverging section 32 exposed to the outside air, and is guided by the capillary action by the siphoning section 31. The liquid evaporates from the upper surface of the diverging section 32 to the outside air.

In the suction part 31, a material which can guide the liquid to the diverging part 32, has appropriate flexibility, and is resistant to the internal solution is appropriately selected. For example, a plastic filament formed with a micro-section passage, a cilia made of an acrylic resin or a polyester resin, a filter paper, or the like, which can guide a liquid by a permeation phenomenon, is preferably used, but is not limited thereto.

The size and shape of the siphoning portion 31 can be variously changed within a range compatible with the container body 10 and the closing lid portion 14. At least the lower end of the siphoning portion 31 can be immersed in the internal solution. It can abut the bottom of the container body 10,
Furthermore, it should not interfere with the smooth attachment and detachment of the closing lid 14.

The suction portion 31 is preferably formed integrally with the diverging portion 32 described below or connected so as to be able to conduct liquid so as not to be detached when the closing lid portion 14 is attached or detached.

As the material of the diverging portion 32 constituting the transpiration mechanism, a material capable of absorbing the liquid and appropriately retaining and evaporating the liquid is appropriately selected according to the properties of the internal solution and in view of the resistance to the internal solution. . For example, a member having communicating porosity made of filter paper, felt, resin sintered body, cloth, pottery, gypsum, or the like is preferable as the material of the diverging portion 32.

The shape and size of the divergent portion 32 are variously selected in accordance with the characteristics of the internal solution within a range compatible with the upper portion of the container body 10 and the closing lid portion 14, and the total area of the transpirating portion is adjusted so that the amount of transpiration Can be controlled.

The diverging section 32 having the suction section 31 is mounted on the closing lid section 14 together with the piston mechanism. Divergence part 32
The gasket 13 is provided with a through-hole such that the lower end of the suction unit 31 is immersed in the liquid stored in the solution main body 10 so as to be exposed to the outside air.

The container of the present invention having the above structure and having both spraying and evaporation functions is capable of spraying a constant amount of liquid in a mist state having excellent diffusion efficiency into the atmosphere regardless of the remaining amount of liquid. In addition, the design and application range of the container are various, and the strength and stability of the container can be improved.

Even when topical spraying is desired, an appropriate amount can be sprayed on a specific site, so that a fragrance, a deodorant, an insecticide, an antibacterial antifungal agent, etc. This is advantageous for use in a mixture, and the amount can be easily controlled by the degree of pressing.

In the container of the present invention, the evaporation can be temporarily stopped by re-fitting the cap to the closing lid at any time after the start of use, and the container can be reused without difficulty. .
