Description

  The present invention relates to a coating material extrusion container for extruding and using a coating material.

Conventionally, the technique of the following patent document 1 is known as a container for extruding and using the substance of cosmetic products and care products. In the container of this patent document 1, the front end surface (application surface) which has the discharge port of the container front end for discharging the said substance is comprised by the inclined surface which inclines with respect to a container axis. And in this container, while the partition part which divides the said discharge outlet into a some area | region is provided in the said discharge outlet, this partition part is extended in the back side in a container, and the said substance in a container is made into the front-end | tip. A flow path for extruding to the side, one flow path communicating with a region on the top side of the inclined surface of the plurality of regions, and a region on the bottom side of the inclined surface of the plurality of regions Thus, the flow path length of the one flow path on the top side is made longer than the flow path length of the other flow path on the bottom side. While the material flows out through the bottom channel prior to the top channel, excess material out of the material through the bottom channel is returned through the top channel, resulting in excessive material discharge. It is a container to prevent
Japanese Patent No. 3633702

  However, in the container, there is a problem in use such that it is difficult to apply the substance because the substance is biased from the region on the bottom side of the discharge port provided on the inclined surface serving as the application surface.

  The present invention has been made to solve such problems, and provides a coating material extruding container in which the coating material is evenly discharged from the discharge port inclined at the tip of the container without unevenness and the usability is improved. The purpose is to do.

  The coating material extruding container according to the present invention is configured to be able to extrude the coating material accommodated therein toward the tip side, and discharges the coating material from the discharge port at the tip of the container through the discharge hole provided in the container. A coating material extruding container, wherein a tip end surface having a discharge port at the tip of the container is configured to have an inclined surface inclined with respect to the container axis, the discharge hole is formed at a portion on the top side of the discharge port. It has a separation part that is divided into a first region that is connected and a second region that is connected to a portion on the bottom side of the discharge port, and the separation part has a cross-sectional area through which the coating material passes through the first region> a coating material passage through the second region. It is provided so that it may become an area.

  According to such a coating material extruding container, the separation part causes the discharge hole to be connected to the first region where the discharge port is inclined at the tip of the container and the second region where the discharge port is connected to the bottom portion of the discharge port. And the coating material passage cross-sectional area of the first region> the coating material passage cross-sectional area of the second region, the coating material moving in the second region close to the discharge port is far from the discharge port. Compared with the coating material that moves in the first region, the coating material moves while being squeezed, and the coating material can be evenly discharged from the top side portion of the discharge port and the bottom side portion of the discharge port. Accordingly, the coating material is discharged evenly from the inclined discharge port at the tip of the container, and usability is improved.

  Here, as a configuration that effectively exhibits the above action, specifically, the separation portion enters the discharge hole from the rear end side, protrudes in the extending direction of the discharge hole, and extends to the vicinity of the discharge port. The structure which divides a discharge hole into a 1st area | region and a 2nd area | region is mentioned.

  Thus, according to the coating material extruding container according to the present invention, the coating material can be discharged evenly from the discharge port inclined at the tip of the container without unevenness, and usability can be improved.
