Description

  The present invention relates to a liquid applicator having a brush that can stably prevent drying of the brush tip due to condensation and maintain the original function of the liquid applicator itself over a long period of time.

  Conventionally, in the case of liquid material applicators having brushes such as brushes and felts, there is no problem in airtightness such as caps covering the brushes regardless of whether the bulk supply is a direct liquid type or a batting type However, writing defects may occur due to drying of the brush tip.

  As one of the factors that cause the brush tip to dry, an example in which the brush tip is dried due to condensation in the cap can be given.

  More specifically, a liquid container filled with a liquid material or a liquid material applicator can be used properly with a brush and a structure with a cap filled with components evaporated from the brush tip. It is in a state that has been.

  At this time, the concentration of the evaporated component in the cap changes depending on the environmental temperature where the container is placed.

  That is, the evaporation component is condensed due to a temperature difference from the inner wall of the container, and the component is newly evaporated from the brush tip in accordance with the volume fraction that is reduced by becoming a water droplet.

  By repeating this phenomenon, the evaporation component from the brush tip continues to decrease, leading to an inconvenient state where writing cannot be performed due to an increase in the pigment concentration of the brush tip or an increase in the resin component.

  On the contrary, if the condensed moisture evaporates and adheres to the brush tip, the bulk at the tip of the brush is thinned, and there is a risk of lowering the pigment concentration of the brush tip.

  Such a situation is based on the temperature difference between the temperature inside the cap and the outer wall of the cap, and various conventional measures such as the following patent documents, for example, putting a part that absorbs condensation into the cap, etc. have been studied. However, it is difficult to cope with various temperature environments.

  In order to solve the above-described conventional situation, the present applicant has further conducted intensive research, experiments, and examinations, and found that it is necessary to make the temperature not only the temperature difference between the inner wall and outer wall of the cap uniform, but also the temperature inside the entire cap. It was.

  That is, if the temperature on the entire inner surface of the cap becomes non-uniform, condensation may occur even at a temperature difference of several degrees at a portion where the temperature difference between the cap outer wall and the inner wall is large.

  Normally, the inner wall of the cap and the inner cap parts use resin to maintain airtightness with the container, but the resin that is usually used has poor thermal conductivity as a characteristic, and is resistant to external temperature changes. It is difficult to make the temperature of the inner wall of the cap uniform, and it is very difficult to cope with a rapid temperature change.
