BRIEF DESCRIPTION OF THE DRAWINGS FIG.
1 is a container-like structure, 2 is a bag-shaped refillable container, 3 is a holder, and 4 is a dispenser body.

The container-like structure 1 has a bottom portion opened, and a separate bottom cover 5 is fitted to the open bottom portion so as to be easily detachable. The diameter of the mouth and neck 6 is erected, and a thread is formed on the outer surface of the lower half of the mouth and neck 6 and a rib 13 is projected inward from a part of the inner surface of the lower half in the circumferential direction. This structure 1 is formed into a hard container body by blow molding of a synthetic resin material, and a bottom wall portion is cut by post-processing to form a main body. The bottom cover 5 is separately formed. The bottom cover 5 has a narrow band-shaped vent hole 14 in the center band of the curved protruding portion at the center. The ventilation hole 14 may be a simple small hole or a ventilation groove provided on the fitting surface of the structure 1 with the inner surface of the lower body. Note that the bottom cover 5 does not necessarily need to be provided.

The refillable container 2 is formed such that the mouth of a bag made of vinyl or the like is airtightly fitted and adhered to the outer surface of the lower portion of the hard mouth tube 7. The mouth tube 7 has a smaller diameter than the mouth and neck portion 6 and is longer than the mouth and neck portion 6, and has a small brim-shaped engaging edge 8 from the upper outer surface and a lower end of the rib 13 from the lower outer surface. A large brim-shaped stopper 15 is abutted, and an elastic peripheral wall 9 is projected from the lower inner surface in an obliquely downward direction. The bag of vinyl or the like of the container 2 may be an extremely simple one made by folding an extremely thin sheet into a bag and bonding the seams.

The holder 3 has a C-shape in which a knob 10 is provided upright from the upper surface of the intermediate portion, and is sized to ride on the top surface of the mouth and neck 6 of the structure 1 and is formed by molding a synthetic resin material. It is possible. Accordingly, as shown in FIGS. 1 and 2, the refillable container 2 housed in the
When the holder 3 on the top surface of the mouth and neck 6 is pushed in while being pulled up to the upper limit for abutting engagement with the lower end, the holder 3 fits into the outer surface of the mouth tube 7 on the lower surface of the engaging edge 8. The refillable container 2 can be stably held. Further, when the refillable container 2 is pulled out by the knob 10, the refillable container 2 falls downward, so that the refillable container 2 can be replaced by one-touch operation of pushing and pulling.

The dispenser body 4 is extremely well-known as described in the background section, and is not directly related to the gist of the present invention.
The cylinder 11 is provided with a cylindrical piston, a return spring, and a suction valve. A stem having a lower end communicating with and fixed to the cylindrical piston is projected upward from the cylinder 11 to the outside. the pressing head 17 which projects the nozzle tube 16 is fixed communication and an interior with the structure of the discharge valve stearyl arm, container-shaped groove body 1 a cap-shaped mounting member 12 is screwed to the neck 6 the outer surface Mounted on In this mounting state, the upper portion of the cylinder 11 is inserted into the mouth tube 7, and at this time, the outward flange 18 at the upper end rides liquid-tight on the upper end of the mouth tube 7 via the packing 19, and the elastic peripheral wall 9 is attached to the outer periphery of the cylinder 11. The inside of the refillable container 2 is hermetically sealed from outside air by pressing against the surface.

In each drawing, the press-down head 17 is screwed with a screw on the lower surface thereof to a screw member on the upper surface of the mounting member 12 so as to keep the head 17 pressed down to the lower limit. 3 shows a state in which a mischievous operation is prevented.

The operation of the dispenser main body 4 is performed by pressing down the head.
