Zusammenfassung: | PURPOSE: To obtain a coating container which prevents the ingress of air, etc., into a bag, is therefore hygienic, and enables even almost the last bit of a liquid to be used, by forming a liquid storage compartment from a deformable bag which shrinks as the liquid is used. CONSTITUTION: In a container main body A, a slide member 3 moves forward by rotating an operation handle 2 in relation to a barrel 1, and a coating member 4 also moves forward interlocking with this, thereby causing a coating part 4a to project from an opening member 5 attached to the front end of the barrel 1. Inside the barrel 1 storing the coating member 4 is a deformable bag 8, for use as a liquid storage compartment, which shrinks as a liquid is used. As the material of the bag 8, soft one such as polyethylene or polypropylene is employed. In the case the liquid has high viscosity, the internal surface of the bag is pulled and shrinks as the liquid is used. In the case where the liquid has low viscosity, on the other hand, such a material as synthetic rubber or thermoplastic elastomer, having self-shrinking force, is used. |
