Description

  The present invention relates to a chemical container for storing or storing a chemical solution such as an external disinfectant or a skin disinfectant, and more particularly to a disposable chemical solution container formed from a plastic sheet.

  When applying chemicals such as external disinfectants and skin disinfectants to the affected area, are the chemicals stored in bottle-shaped containers transferred to small disposable cup-shaped chemical containers for use? 1), or a chemical container (see, for example, Patent Document 2) in which a chemical liquid subdivided into a single use amount is enclosed.

JP 2000-225126 A (particularly FIG. 4) Japanese Patent No. 3635647 (particularly FIGS. 1B and 2B)

  When applying a chemical solution to the affected area using the chemical solution container as described above, pour the chemical solution into the chemical solution reservoir of the chemical solution container, and then apply the chemical solution application part of a chemical solution applicator such as a cotton swab The ball part) is immersed in the chemical solution in the chemical solution reservoir and absorbed by the chemical solution application unit, and the chemical solution is applied to the affected part. At this time, if the drug solution application part contains more than necessary chemical solution, the drug solution may sag, the drug solution may adhere to the affected area more than necessary, or the drug solution may eventually run out. The chemical liquid application part is rubbed against the inner upper edge of the chemical liquid reservoir, etc., and the excess chemical liquid is cut off before application. However, since the chemical solution container is small, it has a problem that it is difficult to easily drain the solution.

  Therefore, the present invention is intended to provide a new chemical solution container that can easily cause the chemical solution absorbed by the chemical solution application part of the chemical solution applicator to run out.

  The present invention is a disposable chemical solution container formed from a plastic sheet, and a plurality of protrusions or step portions are provided on a chemical solution reservoir and an inclined portion inclined downward toward the chemical solution reservoir. A chemical container having a liquid draining portion is proposed.

In the case of a chemical container having such a configuration, the chemical liquid is poured into the chemical reservoir, and the chemical application part of a chemical application tool such as a cotton swab (in the case of a cotton swab, the cotton ball part at the tip) is immersed in the chemical liquid. After absorbing the chemical solution application portion, the chemical solution application portion is rubbed against the liquid cutting portion, so that the excess chemical solution can be easily drained, so that a necessary and sufficient amount of the chemical solution can be applied to the affected area.
In addition, since the inclined portion of the liquid cutting portion is provided so as to be inclined downward toward the chemical liquid reservoir, the chemical liquid application portion of the chemical liquid applicator can be immersed in the chemical liquid along the inclined portion. Even if the reservoir is small, the chemical solution application portion can be sufficiently immersed in the chemical solution. Therefore, since the chemical liquid reservoir can be made small, it is possible to eliminate an excessive amount of chemical liquid remaining after use.
