JPS6024436Y2 - Fitting structure between container body and cylinder in manual sprayer - Google Patents

Description

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

Compared to aerosol sprayers, small manual sprayers that are more commonly used require a cylinder with a suction valve on the inner surface of the bottom to be vertically installed inside the container body, and a parts are required.

For this reason, as well as for other reasons, the container body of an aerosol sprayer uses a metal pin, whereas a bottle made of synthetic resin is usually used in a manual sprayer.

If it is a bottle, the outward flange protruding from the upper edge of the cylinder is placed on the top surface of the bottle, and the lower half of the holding cylinder, which has an inward flange on the inner surface of the intermediate portion, is screwed onto the outer surface of the seed opening. This is because it is easy to clamp the outer flange of the cylinder between the inward flange and the top surface of the seed mouth.

However, when comparing the container bodies, metal container bodies are generally more beautiful due to their superior plating, printing, etc., so it is desirable to use metal container bodies even in manual sprayers. Become.

The purpose of this proposal is to improve this point, and the drawings will be explained below.

1 is a metal container main body, 2 is a body thereof, 3 is a shoulder formed from the upper end of the body in a tapered shape upwardly, and 4 is a shoulder portion formed by winding the upper end of the shoulder outward in a ring shape. This is the edge of the mouth formed by

A recess 5 is formed between the outer surface of the mouth edge and the upper end of the outer surface of the shoulder.

Reference numeral 6 denotes a fitting and holding member, which has a top wall 7 formed in the shape of a brim;
An intermediate peripheral wall 8 is vertically provided from the back surface of the intermediate portion between the outer peripheral edge and the inner peripheral edge.

Its outer diameter is the same as the inner diameter of the mouth edge 4 of the container body.

It is preferable that an engaging protrusion 11 having upwardly facing step portions 9, 9 and having an inclined surface 10, 10 that reduces the thickness of the lower end from the tip thereof is provided hanging from the lower end of the intermediate peripheral wall.

Further, an outer peripheral wall 12 is provided hanging from the outer peripheral edge of the top wall.

The inner diameter of the outer circumferential wall is the same as the outer diameter of the mouth edge 4, and the lower inner edge thereof is provided with a claw protrusion 1 that can be fitted into the recess 5 described above.
It is recommended to add 3.

Its lower inner surface has a sloped surface 14 with a large lower inner diameter, and when fitting, simply pressing down from above will guide the opening edge 4 to the inside of the outer peripheral wall, and the claw protrusion 4 will be guided by the sloped surface. 13 is preferably provided so as to fit into the recess.

An inner peripheral wall 5 is vertically provided from the back surface of the inner peripheral edge of the top wall 7.

From the inner circumferential edge of the fitting holding member, there is an engagement protrusion 16 on the upper inner circumference.
It is preferable to protrude the retaining cylinder 17 having a cylindrical shape, and to erect the cap fitting cylinder 18 which opens the engaging cylinder with an appropriate gap.

Reference numeral 19 denotes a cylinder for sucking up liquid that is vertically installed within the container body, and 20 is a suction pipe that is installed vertically from the lower end of the cylinder.

An outward flange 22 projects from the upper end of the peripheral wall 21 of the cylinder.

A concave groove 23 for fitting the inner circumferential wall 15 on its upper surface.
be established regularly.

The portion 24 between the groove and the outer circumferential surface of the outward flange can be fitted between the inner circumferential wall 23 and the intermediate circumferential wall 15 at the time of fitting.

An O-ring 4a is fitted between the mouth edge 4 and the upper part of the intermediate peripheral wall.

The illustrated sprayer is a pressure accumulation type sprayer developed by the present applicant and which has many existing applications, 25 a sliding tube having upper and lower tubular piston parts, 26 a large diameter cylinder, 27 a spray head having a nozzle hole 28, 29 is a communication pipe that allows the liquid in the large diameter cylinder to be ejected from the nozzle hole via the discharge valve;
is a cap.

The present invention has the above-mentioned structure, in which the intermediate circumferential wall 8, the outer circumferential wall 12, and the inner circumferential wall 15 are vertically disposed from the back surface of the top wall formed in the shape of a brim to form a fitting and holding member. Simply fit the mouth edge 4 of the container body between the two, the portion 24 between the concave groove 23 of the cylinder outward flange and the outer circumferential surface, and the inner circumferential wall 23 within the concave groove 23 with difficulty in separation. Therefore, the structure of each member is easy to assemble, and by using an O-ring 4a at the fitting portion, liquid leakage can be prevented and the fitting can be made watertight.

In this way, the container body can be made of a normally used metal nail with a seamed rim 4, and in this way it is possible to create a manual atomizer with an appearance comparable to that of an aerosol atomizer. I can do it.
