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.

In general, manual sprayers tend to have a more complicated spray body structure than aerosol sprayers, and the higher the performance, the more complicated the structure, and therefore the higher the cost.This proposal is a series of steps to simplify this and reduce costs. This is one of the improvements made to the above, and the drawings will be explained below.

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 edges of the opening are folded back and rolled up to form a circular cross section, as is usually done.

Reference numeral 5 denotes a manual sprayer main body having a spray member 8 whose lower part is inserted into a cylinder having an outward flange 6 attached to the upper end, and a spray head 9 attached to the upper end of the spray member against urging. When pressed down, the internal pump operates and the liquid inside the cylinder is sprayed, and when the spray head is released, the spray head rises and the liquid inside the container flows from the lower end of the cylinder into the container through a suction pipe. It is designed to be sucked into the cylinder.

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 holds the outer circumference of the outward flange 6 of the cylinder watertightly and annularly 12 at a portion of the cylinder via a packing 11 or the like.

Further, the lower part is folded upward and outward at an appropriate interval to form an upright peripheral wall part 13, and the tip thereof is further folded downward and outward to form a reverse groove-shaped part 14, and the reverse groove-shaped part is formed. is fitted onto the upper outer surface of the mouth edge 4 of the container body through a packing 15 in a watertight manner.

Further, the upright peripheral wall portion adjacent to the reverse groove-shaped portion is bent to have a dogleg-shaped cross section 16, and its upper outer surface portion 16a is brought into contact with the lower inner surface of the mouth edge portion 4 of the container body.

As shown in the figure, an upright peripheral wall portion 17 is further protruded from the upper end portion where the outward flange is clamped 12 to prevent the spray member from being extracted upwardly through the engagement step portion 18 directed downwardly and inwardly. The fitting cylinder portion 19 may be formed to prevent the above.

The present invention has the above structure, and since the connecting member 10 is made of a metal plate, it can be easily and inexpensively shaped by pressing or shaping, and the outer periphery of the outward flange of the manual sprayer body is made watertight with a part of the cylinder. The lower part of the wall 12 is folded upwardly and outwardly at an appropriate interval to form an upright peripheral wall part 13, and the tip thereof is formed into a reverse groove-like part 14, which is connected to the upper outer surface of the container mouth edge 4. Since the main body of the manual sprayer is fitted to the container body through packing, the outward flange of the cylinder is supported in advance, and then the reverse groove-shaped portion is fitted to the mouth edge 4 of the container body. This can be easily done by bending the portion of the upright peripheral wall portion 13 of the connecting member close to the inverted groove-shaped portion into a dogleg shape in cross section, and aligning the upper outer surface portion 16a with the rim of the container body. Since the connector is brought into contact with the lower inner surface of the portion 4, the fitting between the connector and the container body is ensured, and the manual sprayer body will not come off from the container body even though it has a considerable weight.

Furthermore, since the lower part of the supporting part, the bottom wall part formed by folding the supporting part, and the upright peripheral wall part 13 are interposed between the part supporting the outward flange and the part fitted to the mouth edge of the container body, these parts are sprayed. When force is applied to the member, it acts as a buffer and breaks apart, making it highly durable.

Claims (1)

[Scope of utility model registration request] A manual sprayer main body 5 has a metal container body 1 whose upper opening edge is folded back and formed into a mouth rim 4, and a cylinder 7 and a spray member 8 whose lower part is inserted into the cylinder. and a connecting member 10 made of a metal plate for attaching the sprayer main body vertically into the container body, and the connecting member is connected to the outer peripheral edge of the outward flange 6 protruding from the upper end of the cylinder of the sprayer main body. The cylindrical part is supported in a watertight and annular manner through a packing 11, and the lower part thereof is folded upwardly and outwardly at an appropriate interval to form an upright peripheral wall part 13.
The tip is further folded downward and outward to form a reverse groove-shaped portion 14, and the reverse groove-shaped portion is fitted to the upper outer surface of the mouth edge 4 of the container body through a packing 15 in a watertight manner. The upright peripheral wall portion adjacent to the reverse groove-shaped portion is bent into a dogleg shape in cross section (e, 16), and the upper outer surface portion (16a) is brought into contact with the lower inner surface of the container mouth edge portion (4).
