Abstract

PURPOSE:To enhance rustproof and anticorrosion effect, by applying a protective film to the inner surface of a can after molding and inserting a valve assembly in a holder part through a packing and caulking the outer periphery of the holder part by a cover. CONSTITUTION:The matrix body of a can 2 composed of a bottomed cylindrical body is subjected to press molding to provide a shoulder part 4, a neck part 5 and a holder part 6 on a can body part 3. Next, a protective film 8 is formed to the entire region of the inner peripheral surface of the can 2. In the next process mounting a valve assembly 10, a packing 9 is fitted onto the outer periphery of a valve housing 12 and the valve housing 12 is inserted in the holder part 6 and the neck part 5 so as to bring the packing 9 into contact with the inner peripheral surface of the holder part 6. Subsequently, a cover 11 is allowed to cover the upper part of the valve assembly 10 and the lower end part 17 of the cover 11 is caulked to be engaged with a string 7. As a result, the valve assembly 10 is strongly fixed to the can 2 without damaging the protective film 8.

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing an aerosol device. More specifically, the present invention relates to a method for manufacturing an aerosol device having a high performance protective coating.

[Prior art] Aerosol devices that use metal cans may suffer from corrosion or corrosion depending on the type of liquid they fill, or the content may react with metals, especially aluminum, causing deterioration (discoloration and odor). (e.g.), the inner surface of the can body is sometimes painted to prevent rust and corrosion.

In this case, if a manufacturing method is used in which the inside of the can body is painted and then the shoulders and neck are formed on the can body, the coating film is often damaged due to bending of the shoulders and neck, resulting in poor rust and corrosion prevention effects. There is a problem that this occurs. In order to avoid damage to the paint film, if a paint that forms a soft film is used, the rust and corrosion prevention effects will still not be sufficient due to insufficient hardness.

In order to avoid the above problems, a manufacturing method was considered in which the shoulders and neck were first formed on the can body, and then the inside of the can body was painted. In this case, as shown in FIG.
) has a shoulder part (52) and a curling part (5) which becomes the neck part.
The inner surface of the can is painted by putting the coating nozzle (5B) into the can (50) in which the can (50) is formed and pulling up the nozzle (56) from the bottom to the top while rotating the can (50).

However, with such a manufacturing method, as shown in FIG. Since it is not possible to paint the surface, some areas remain without a paint film. Since the upper surface of this curling part (53) is curved in an arc shape, the content liquid tends to leak, and the content liquid is transferred to the can (50).
It may be pushed by the pressure inside and leak out through the gap with the gasket (55) as shown by the arrow (A). In this case, rust and corrosion easily occur on the outer surface of the curling part (53), and the rust gets mixed into the liquid inside the can (53).

In the manufacturing method of the present invention, since the can is formed into its final shape before coating to form a protective coating, the coating that is subsequently formed is not subjected to any drawing or bending processes. Therefore, no damage occurs to the paint film. In addition, the holder part is funnel-shaped and its inner circumferential surface faces the can axis direction, so the holder part can be completely coated with a coating film using the usual coating method that involves inserting a coating nozzle inside the can. can be formed. Therefore, formation defects of the protective coating film will not occur.
