Abstract

PROBLEM TO BE SOLVED: To spray a liquid in atomized state at high diffusion efficiency regardless of the remaining amount of the liquid by installing a nozzle to spray a liquid stored in the inside of a container main body, immersing the lower end part in the liquid in the inside of the container main body, and transpirating the liquid from a pumping up part to the outside from the upper face of a diffusion part. SOLUTION: A ball 25 is so pushed down as to choke the end part of a communicating pipe 26 by pushing a cap 11, pressure is applied to the pump casing 24 filled with a liquid, and the liquid is pumped up toward a spraying nozzle 21 from the inside of a piston 23, pumped out through a spiral groove 28, and sprayed in atomized state. Moreover, while the lower end part of a pumping up part 31 being immersed in the liquid stored in the inside of the container main body 10, the pumping up part 31 is extended to an evaporation part 32 exposed to the outer air. Due to the capillarity of the pumping up part 31, the liquid is evaporated to the outside from the upper face of the evaporation part 32. Consequently, regardless of the remaining amount of the liquid, a proper amount of the liquid can be constantly sprayed in atomized state at high diffusion efficiency to the atmosphere.

Description

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 evaporating functions. More particularly, it stores liquids, in particular volatiles, such as fragrances, deodorants, insecticides or antifungal agents, etc. or mixtures thereof,
The present invention relates to a container that includes both a spraying mechanism using a pump for spraying a liquid and a vaporization mechanism, and can always vaporize a liquid while spraying an appropriate amount at various places or in the atmosphere as desired.

[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 spontaneously evaporating the liquid. For example,
Tokuhyo 6-504480 uses an elastically deformable container, a mechanism for instantaneously discharging the content liquid by grasping and pressing the container body with a hand, and a liquid absorbing material using the penetration phenomenon. Disclosed is a dispenser provided with a mechanism for performing spontaneous evaporation.

However, this dispenser has a complicated structure and requires two pipes, a discharge pipe for discharging the liquid and a liquid guide pipe for guiding the liquid to evaporate the liquid. The member becomes large and therefore the entire container becomes large. Further, depending on the shape of the container body, the lower end of the liquid-absorbent material guide tube abuts the container body, so that it is necessary to pay attention to the attachment of the inner plug member.

Therefore, a flexible suction portion or an acrylic resin or a polyester resin, which is manufactured by aligning and solidifying a large number of plastic filaments in the liquid-absorbent rod-shaped suction portion which plays the role of the guide tube in the above invention. A liquid fragrance that realizes a simplified structure and a smaller size by using a flexible suction part that is formed by solidifying cilia consisting of A drug container was proposed (Japanese Patent Application No. 6-17886 and Japanese Patent Application 6-1).
See 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 filled with liquid. Even when the volume of the gas phase is comparatively small, it is difficult to spray into the atmosphere in the form of water droplets and into a fine mist with excellent diffusion efficiency. Further, the gas phase becomes larger as the remaining amount of liquid in the container body decreases, and it is difficult to spray without pressing with a strong force, and in some cases, the dripping fragrance is attached to the hand. Therefore, if the material forming the container body is made flexible so that the container body can be sufficiently pressurized even with a weak force, the strength is unavoidably reduced. Further, according to the above mechanism, it is difficult to control the spray amount.

Furthermore, the material of the container body, the necessity to make it a preferable form for gripping and pressing, etc. have become a factor that greatly limits the variety of container designs that should be accommodated to the taste. Further, since the material of the container body having elasticity is limited, the physical properties of the liquid that can be stored therein are necessarily limited, and the application range of the container is extremely narrow.

As described above, a container for liquids having both spraying and evaporating functions, always spraying a fixed amount of liquid in a mist state with excellent diffusion efficiency to the atmosphere regardless of the remaining amount of liquid. However, there are no proposals for containers with various designs and scopes.

[0008]

Means for Solving the Problems As a result of intensive studies in view of the present situation, the present inventors have found that, in addition to the evaporation mechanism,
It has been found that the above-mentioned problems can be solved by adopting a structure in which a pump mechanism with a spray nozzle is adopted to spray the liquid stored in the container body, and has completed the present invention.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A liquid container having both spraying and evaporating functions of the present invention is a container main body, a pump mechanism having a spray nozzle for spraying the liquid stored in the container main body, and a suction mechanism. And a transpiration mechanism configured by a divergent part, wherein the suction part is soaked in the liquid stored in the container body at least at the lower end part thereof and extended to reach the divergent part exposed to the outside air. The liquid guided by the suction part is evaporated from the upper surface of the diverging part to the outside air.

Further, the container of the present invention preferably has a cap which can be fitted into a closing lid part screwed to the upper part of the container main body to which the spray nozzle is attached, and the cap is attached to the upper part of the container main body. A partition wall is provided in the cap, which is in close contact with the upper surface of the diverging portion forming the evaporation mechanism when fitted to the closing lid portion attached to the. Therefore, when the container is turned over at the time of fitting the cap, it is possible to prevent the liquid from leaking from the diverging portion into the cap, and the content liquid does not drip 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 which is not desired to directly contact the human body is stored and used.

The above structure not only facilitates the control of the spray amount but also makes it possible to select various container materials.
It is expected that the versatility of the container design and the liquid that can be stored will increase and the range of application will increase, and that the structural and functional stability and safety of the container can be improved.

Further, when it is desired to spray to a specific part, the conventional product cannot be sprayed at an angle, especially when the residual liquid amount is decreased, 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 remarkably widened, and therefore, when used for a fragrance, a deodorant, an insecticide, an antibacterial fungicide, or the like, or a mixture thereof. It is advantageous. For example, even if it is directed toward the side wall or the like near the floor where moisture is likely to stay, it can be sprayed extremely easily.

[0013] In the container of the present invention, evaporation can be temporarily stopped by refitting the cap with the closing lid portion even after the start of use, and the container can be reused without difficulty.

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 vertical sectional views showing one embodiment of the container of the present invention. In Fig. 1, when the cap is fitted,
After the cap is opened, FIG. 3 shows the state when the cap is pressed. FIG. 4 shows the state when the cap is fitted, that is, FIG.
The perspective view in the case of is shown.

As described above, the present invention is a container 1 for liquids having both spraying and evaporating functions, which is a container body 10.
And a pump mechanism having a spray nozzle 21 for spraying the liquid stored in the container body 10, and a vaporization mechanism composed of a sucking section 31 and a diverging section 32.

The container body 10 may have any shape as long as it can be equipped with a pump mechanism and a vaporization mechanism, but it is easy to grasp when the liquid is sprayed by pressing the pump head, and it is placed on the floor or shelf. It is preferably a stable shape that does not easily roll over when placed.

Various materials can be selected for the material of the container body 10. For example, plastic resin (olefin resin containing polypropylene and polyethylene, ester resin containing polyethylene terephthalate and polystyrene, vinyl resin containing vinyl chloride, Valex). (Registered trademark)
It is possible to use acrylic resin containing, as well as polymethylpentene (PMP), glass, pottery and the like. Polypropylene, polyethylene, polyethylene terephthalate, Valex (registered trademark), vinyl chloride, polymethylpentene (PMP) or glass is particularly preferable in consideration of weight, strength and compatibility with the liquid to be stored. With these materials, it is possible to create containers of various designs and colors according to various tastes.

The liquid stored inside the container body 10
Properties such as pH, volatility and resin solubility, as well as components contained in the liquid (active ingredients such as fragrances, deodorants, insecticides or antifungal 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 by staying for a long time. Since various materials can be used for the container of the present invention, it can be used for a liquid which cannot be applied to the conventional container which requires the flexibility as described above.

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 liquid feeding, a spring 22 for operating the piston, and a pump. 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 with the communication pipe 26 and the container main body 10 via the closing lid portion 14.
Is screwed on. At the time of screwing, the gasket 13 is inserted between the container body 10 and the container body 10 to prevent leakage of the internal solution pushed up when the pump is pressed from the container opening.
The spray nozzle 21 is one in which a thin groove is spirally provided around the liquid discharge portion, and when the content liquid passes through the narrow groove due to pressurization, it 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 which can be fitted to a closing lid portion 14 screwed to the upper part, and when the cap 11 is fitted to the closing lid portion 14 mounted on the upper part of the container body 10, the evaporation mechanism is formed. Divergent part
A partition wall 12 is provided in the cap 11 so as to be substantially in contact with the upper surface 32. Therefore, when the container 1 rolls 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 aspect, the pump mechanism may be rotatably screwed to the container body 10 via the closing lid portion 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 and when the cap is fitted (see FIG. 1): The piston mechanism, together with the communicating pipe 26 and the cap 11,
It is fitted to a closing lid portion 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 the elastic force for pushing up the cap 11 is stored. As described above, since 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 so-called sealed state, when the liquid is tumbled in the state of FIG. Leakage into the cap 11 and subsequent dripping when releasing the cap is prevented.

2) When the cap is released and at rest (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, which serves as a check valve, floats up, and an amount of liquid corresponding to the increased pump internal volume is fed into the pump casing 24 through the communication pipe. Since the volume of the vapor phase in the container body 10 is reduced by the volume of the liquid fed into the pump casing 24, the container body 10 is prevented from having a negative pressure.
A slit 27 is provided in the pump casing 24 so that the outside air is sucked into the 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 the liquid. . This pressure pushes the liquid from inside the piston 23 toward the spray nozzle 21. Since the liquid reaches the spray nozzle 21 attached to the cap 11 and is extruded through the spiral groove 28, it can be ejected in a mist state. When the pressing of the cap 11 is released, the elastic force of the compressed spring 22 causes the pump mechanism to return from the pressed state to the stationary state. At this time, 2)
Liquid is pumped back into the pump casing 24 as described in.

Another mechanism that characterizes the liquid container 1 of the present invention is a vaporization mechanism including a sucking section 31 and a diverging section 32 (see FIGS. 1 to 3). At least the lower end portion of the suction portion 31 is immersed in the liquid stored in the container body 10 and extends to reach the divergence portion 32 exposed to the outside air, and the suction portion 31 is induced by a capillary phenomenon. The liquid is evaporated from the upper surface of the diverging section 32 to the outside air.

For the suction part 31, a material capable of guiding the liquid to the divergent part 32, having appropriate flexibility, and having resistance to the internal solution is appropriately selected. For example, plastic filaments having fine cross-section passages capable of inducing a liquid by a permeation phenomenon, cilia made of acrylic resin or polyester resin, filter paper, and the like are preferably used, but not limited thereto.

The size and shape of the suction part 31 can be variously changed within a range that fits the container body 10 and the closing lid part 14, but at least the lower end part of the suction part 31 can be immersed in the inner solution, and preferably, Can abut the bottom of the container body 10,
Further, it should not interfere with the smooth attachment and detachment of the closing lid portion 14.

The suction portion 31 is preferably formed integrally with the diverging portion 32 described below so as not to be detached when the closing lid portion 14 is attached or detached, or is connected in a state capable of conducting liquid.

As the material of the divergence section 32 constituting the evaporation mechanism, a material capable of absorbing and retaining liquid and appropriately evaporating is appropriately selected depending on the properties of the inner solution and in view of the resistance to the inner solution. . For example, a member having continuous porosity such as filter paper, felt, resin sintered body, cloth, pottery or gypsum is preferable as the material of the diverging portion 32.

Within the range suitable for the upper part of the container body 10 and the closing lid part 14, the shape and size of the divergent part 32 are variously selected according to the characteristics of the internal solution, and the total area of the transpiration part is adjusted to adjust the transpiration amount. Can be controlled.

The diverging portion 32 having the suction portion 31 is attached to the closing lid portion 14 together with the piston mechanism. Divergence part 32
Is disposed in the closing lid portion 14 so as to be exposed to the outside air, and at this time, a through hole is provided in the gasket 13 so that the lower end portion of the suction portion 31 is immersed in the liquid stored in the solution body 10.

The container of the present invention having both the spraying and evaporating functions, which has the above-mentioned structure, always sprays a certain amount of liquid in the form of mist, which is excellent in the diffusion efficiency into the atmosphere, regardless of the remaining amount of the liquid. Further, the design and application range of the container are various, and the strength and stability of the container can be improved.

Further, even when local spraying is desired, since an appropriate amount can be sprayed to a specific site, a fragrance, a deodorant, an insecticide, an antibacterial antifungal agent, or the like or these It 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 refitting the cap with the closing lid portion even after the start of use, and the container can be reused without difficulty. .

According to the present invention, there is provided a liquid container having both spraying and evaporating functions and capable of spraying an appropriate amount of liquid in a mist state which is always excellent in diffusion efficiency to the atmosphere regardless of the remaining amount of liquid. To be done.

Further, in a preferred embodiment, when the container is turned over at the time of fitting the cap, it is possible to prevent the liquid from leaking from the diverging portion into the cap, and the contents liquid drips when the cap is opened. There is an effect that there is no. In particular, this leakage prevention function is important when a liquid such as an antibacterial / antifungal agent or an insecticide which is not desired to directly contact the human body is stored and used.

Further, according to the container of the present invention, not only the control of the spraying amount becomes easy, but also the container material can be selected variously, so that the variety of the container color, the design and the liquid that can be stored is increased. In addition to widening the scope of application, it is possible to enhance the structural and functional stability and safety of the container.

Further, when it is desired to spray to a specific part, the conventional product cannot be sprayed with an inclination especially when the residual liquid amount is decreased, and it is difficult to spray other than above the container.
