Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with an applicator for an application agent such as a hair dye or a hair agent.

[0002]

2. Description of the Related Art Conventionally, a container with an applicator has been used
As described in JP-A-19923, a dip tube is provided inside a flexible container main body, and an application tool is provided at a discharge port communicating with the dip tube.

[0003]

However, the prior art has the following problems. Since the dip tube has an opening near the bottom at the bottom of the container body in the vertical direction, the dip tube is pushed out from the dip tube toward the applicator when the applicator is ejected from the applicator.
As a result, at the time of discharging the coating material, the opening of the dip tube needs to be positioned at the lower part in the vertical direction of the container body, and can be discharged only in the container erect state.

The flexible container body is pressurized and squeezed to discharge the coating agent, and then sucks air to restore the bending due to the squeeze deformation and prepare for the next discharge. For this reason, as the amount of the coating material decreases, the air inside the container body increases, and the air tends to be scattered out of the range of the application target portion due to air entrapment.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a container with an applicator, which can discharge the coating material in any posture of the container, and prevents the coating material from being scattered by air even when the remaining amount of the coating material becomes small.

[0006]

According to the present invention, there is provided a container with an applicator according to the present invention, comprising a flexible outer layer and an inner layer releasably laminated on the outer layer. It has a container body provided with an air introduction hole and having a discharge port communicated with the inner layer, and an applicator connected to the discharge port of the container body.

[0007]

According to the first aspect of the present invention, the following operations are provided. When the coating material is discharged from the coating device, the flexible outer layer and the inner layer are squeezed and the container is pressurized, and the coating material is extruded and discharged from a discharge port communicating with the inner layer to the coating device. Then, by releasing the squeeze, air is introduced between the outer layer and the inner layer, the outer layer is restored, the peeling of the inner layer proceeds, and only the inner layer is peeled and shrunk according to the discharge of the coating agent. The outer shape of the container body is not changed at all by the restoration of the outer layer. That is, the coating material is constantly pushed up to the ejection port side by the shrinkage deformation of the inner layer, and does not require a dip tube. Therefore, the coating agent can be discharged regardless of whether the container is in the upright or inverted posture.

[0008] Air for restoring the deflection of the flexible outer layer due to squeezing deformation enters between the outer layer and the inner layer,
Do not enter inside the inner layer. Therefore, even if the remaining amount of the coating agent inside the inner layer becomes small, the coating agent can be stably applied to the application target portion without being entrapped by air and scattered due to its viscosity.
