Description

[Detailed Description of the Invention] The present invention relates to the structure of the fitting part between the container body and the manual sprayer body.

Manual sprayers generally tend to have a more complex structure than aerosol sprayers, and the higher the performance, the more complicated the structure, and therefore the higher the cost.

The present invention is one of a series of improvements to simplify this and reduce costs, and will be described below with reference to the drawings.

Reference numeral 1 designates a metal container body, 2 a body thereof, 3 a shoulder projecting upwardly and inwardly from the upper end of the body, and 4 a mouth edge formed at the upper end thereof.

The edge of the opening is formed into a circular cross section by folding and tightening the ends as is usually done.

5 is a cylinder 7 with an outward flange 6 attached to the upper end.
and a spray member 8 whose lower part is inserted into the cylinder.When the spray head 9 attached to the upper end of the spray member is pushed down against the bias, the built-in pump is activated. When the spray head is released, the liquid inside the cylinder is sprayed, and when the spray head is released, the spray head rises and the liquid inside the container is sucked into the cylinder from the bottom end of the cylinder through a suction pipe that hangs vertically into the container. be.

Incidentally, the main body of the sprayer may be a known one. The above-mentioned sprayer main body is installed by vertically disposing the sprayer main body inside the container body by means of a connecting member 10 made of a metal plate.

The connecting member has an inner/outer double cylindrical shape with a folded part 11 at the lower end, the upper part of the inner cylindrical part 12 is bent inward to form an inward flange-shaped part 13, and the lower end of the flange-shaped part has a folded part 11. The outward flange 6 of the cylinder is brought into contact with the backing 6a, and both the inner and outer cylindrical portions located below the backing 6a are bent to contact the lower surface of the flange 6, and the bent portion 14 and the inward flange-like portion 13 are bent. The flange 6 of the cylinder is held between the two.

In addition, the upper end of the outer cylindrical portion 15 is folded downward and outward to form a reverse groove-shaped portion 16.
The inverted groove-shaped portion was fitted onto the upper outer surface of the mouth edge 4 of the container body through a backing 17 in a watertight manner.

In addition, as shown in the figure, the inward flange-like portion 13 has a reverse groove-like portion 16.
It is desirable that the flange 6 of the cylinder, and therefore the atomizer body 5, be located lower within the container body, so that the atomizer head does not protrude too long and become an obstruction.

Further, it is preferable that the outer cylindrical portion adjacent to the reverse groove-shaped portion is bent into a dogleg-shaped cross section 18 so that the rising surface portion 19 thereof is brought into contact with the lower inner surface of the container edge 4.

Further, from the inner end of the inward flange-shaped portion 13, a standing peripheral wall portion 2 is formed.
0 may be formed in the fitting cylindrical portion 22 to protrude and prevent the spray member from being pulled out upwardly via the downwardly directed engaging step portion 21.

The present invention has the above-mentioned configuration, and since the connecting member 10 is made of a metal plate, it can be easily and inexpensively formed by press molding, and is formed into a double inner and outer cylinder shape with a folded part 11 at the lower end. is an inward flange-shaped portion 13, and the flange of the cylinder is brought into contact with the lower surface of the cylinder through the backing 6a, and both the inner and outer cylindrical portions located below are bent toward the lower surface of the flange, thereby forming a connection between the bent portion and the inward flange. Since the flange of the cylinder is held between the outer cylinder part 13, the cylinder is held extremely reliably by the connecting member, and the reaction force caused by pressing down the spray head can be sufficiently supported.
The upper end is folded downward and outward to form a reverse groove-shaped part 16, which is watertightly fitted to the rising surface of the container edge 4 via a backing 17, thereby connecting the sprayer main body 5 to the container body via a connecting member. In addition, the connecting member is formed with a folded part 11, and the flange of the cylinder is fitted into the inner cylindrical part, and the edge of the container is fitted into the outer cylindrical part. Since the folded part acts as a buffer part, it is not easily damaged even when a large amount of force is applied to the spray head, and has high durability.

Claims (1)

[Scope of utility model registration request] A metal container body 1 having a mouth edge 4 formed by folding and sealing the upper opening edge, and a manual sprayer main body 5 having a cylinder 7 into which the lower part of a spraying member 8 is inserted. , and a connecting member 10 made of a metal plate for vertically mounting the sprayer body into the container body, and the connecting member has a double inner and outer cylinder shape with a folded part 11 at the lower end. The upper part of the part 12 is bent inward to bring the outward flange 6 of the cylinder into contact with the inward flange part 13 and the lower surface of the inward flange via the backing 6a, and both the inner and outer parts located below The cylindrical portions are bent together toward the lower surface of the flange 6, so that the flange of the cylinder is held between the bent portions 14 and 14 and the inward flange-like portion 13, and the upper end of the outer cylindrical portion 15 is folded downward and outward. The fitting between the container body and the sprayer main body is characterized in that the inverted groove portion is watertightly fitted to the upper outer surface of the mouth edge 4 of the container body via a backing 17.
