Abstract

PROBLEM TO BE SOLVED: To allow content liquid to be used up without residual by forming, on an internal bottom face of a liquid container, a slope extending from a center toward an outer rim and a groove whose bottom is inclined from an outer rim toward a center. SOLUTION: A mouth 5 formed with a screw 4 around an outer periphery in order to attach a cap 3 to an opening of a container body 2 is included, and a slope 7 extending from a center toward an outer rim 6a and a groove 8 whose bottom is inclined from an outer rim toward a center are formed on an internal bottom face 6. In addition, a liquid sucking core 10 with a vertical groove 13 inscribed on a side is inserted so that it is in tight contact with an inner wall of an insertion hole provided on an inner lid 9 fitted into the mouth 5, and its lower part is fitted into a concentric recess 12 provided at a center of the bottom for holding. When there is little content liquid left, the content liquid is gathered to the outer rim 6a along the slope 7, further gathered to the center from the outer rim along the groove 8 and sucked by the liquid sucking core 10, so that the content liquid can be used up with no residual.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a liquid container.
More specifically, the present invention relates to a liquid container that can be used up without using a content liquid such as a vaporizer or an aromatic deodorant liquid.

[0002]

2. Description of the Related Art Conventionally, a liquid content contained in a container is sucked up by a capillary phenomenon by a liquid absorbing core immersed in the liquid content and vaporized into the outside air. (See Japanese Utility Model Laid-Open No. 56-152647).

[0003]

However, since the center of the bottom of such a volatilization container has a curved dome shape in the container in order to secure the stability of installation, when the content liquid is low, the content liquid is reduced. It accumulates on the outer edge of the bottom and prevents the absorbent core from being immersed in the content liquid. Therefore, the content liquid cannot be used up to the last drop, which is uneconomical.

[0004] In view of the circumstances described above, an object of the present invention is to provide a liquid container that can be used up without exhaustion of the content liquid.

[0005]

SUMMARY OF THE INVENTION A liquid container according to the present invention is a liquid container in which a liquid contained in the container is sucked up by a liquid-absorbing wick to evaporate the liquid, and the liquid container has an inner bottom surface.
It is characterized in that an inclined portion is formed from the central portion to the outer edge, and a groove formed in the inclined portion, the bottom of which is inclined from the outer edge toward the central portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid container according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an embodiment of the liquid container of the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, FIG. 3 is a sectional view taken along line BB in FIG. 1, and FIG. FIG. 6 is a partially cutaway perspective view showing one usage example of the liquid container of FIG.

As shown in FIGS. 1 to 3, a liquid container 1 according to an embodiment of the present invention includes a bottomed container main body 2 for containing a content liquid such as a solution containing an insecticidal component or the like. An opening 5 on the outer periphery of which a screw 4 is formed in order to attach the cap 3 to the opening of the container body 2, and an inner bottom surface 6 having an inclined portion 7 extending from a central portion to an outer edge 6a; A groove 8 is formed in the inclined portion 7 and has a bottom portion inclined from the outer edge toward the central portion.

An inner lid 9 is fitted in the mouth 5. A liquid absorbent core 10 is inserted into the inner lid 9 so as to be in close contact with an inner wall 11 of an insertion hole provided in the inner lid 9. The liquid absorbent core 10 is held by being fitted into a concentric concave part 12 whose lower part is provided at the center of the bottom. A vertical groove 13 is formed on a side surface of the liquid absorbing core 10. For this reason, the liquid container 1 is not completely sealed, and the pressure in the liquid container 1 can be kept equal to the external pressure. Even so, the rising internal pressure can be released by the vertical groove 13 and the oozing of the liquid can be prevented. The liquid absorbing core 10 can be manufactured by molding an organic and / or inorganic powdery substance using a paste, for example.

In the present embodiment, when the content liquid is low, the content liquid is collected at the outer edge 6a along the inclined portion 7, and further collected at the center through the groove 8 from the outer edge. The content liquid collected in the central portion is sucked up by the absorbent core 10, so that it can be completely used up.

As shown in FIG. 4, for example, the liquid container 1 is covered with an electric heating element 14 on an outer peripheral portion of the liquid absorbing core 10 exposed from the liquid container 1, and is sucked up by forced heating by the heating element 14. It can be used for a heat evaporator that gradually evaporates and evaporates the content liquid.

[0012]

As described above, according to the present invention,
On the inner bottom surface of the liquid container, a slope formed from the center to the outer edge, and a groove formed on the slope, the bottom of which is inclined from the outer edge toward the center is formed, so that the content liquid is formed. It can be used up without excess.
