Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a valve can container in which a valve assembly cap is tightly and caulked directly to the opening of the can container.

The conventionally known valve A and can container B are as shown in the half-sectional view of the valve A shown in FIG. On the other hand, the assembly cap 2 has a downwardly curved outer periphery 3 on its outer periphery. The can container B and the assembly cap 2 are the assembly cap 2.
After fitting the curl ring part 1 into the inner diameter part of the lower curved outer circumferential part 3 of At least partially secured by caulking. However, the can container B is difficult to manufacture due to the curl ring part 1, the manufacturing efficiency of the container itself is reduced due to poor curling, and in addition to these, the number of steps is increased, causing an increase in costs. There are drawbacks.

The present invention eliminates the conventional curl ring part 1, and the can container has an outer diameter part that closely contacts the fitting part with the assembly cap 2, and an obliquely inclined part at the upper part that is connected to this and extends to the opening edge. 7b and which has an open end in line contact with the packing material 4, thereby eliminating the various drawbacks mentioned above.

Hereinafter, the drawings showing the embodiments of the present invention will be described. Fig. 1 is a half-sectional view showing the fixed part between the conventional can container B and the valve, and Fig. 2 is a longitudinal cross-sectional view of the new can container C. Figures 3 and 3 are partially half-sectional views of the fixed portion between the new can container C and the valve, and Figure 4 shows another embodiment.

The can container C has a general cylindrical body 5, has a bottom part 5a on the lower surface that is integral with the body, and has an assembled cap 2 attached to the outer periphery from the opening edge 7c of the opening 5b on the upper surface.
A fitting part 7 is provided within a certain size range, and an outer diameter part 7a is provided in the middle and lower part of the fitting part 7 in close contact with the inner diameter part 3a of the assembly cap 2, and an opening is provided continuously thereto. An inclined portion 7b is formed in the upper portion reaching the end edge 7c so that the diameter of the opening 5b on the upper surface becomes the minimum diameter. The dimensions of the outer diameter portion 7a and the inclined portion 7b and the degree of inward processing of the inclined portion must be such that the inclined portion stands upright in the oblique direction without being bent.In particular, the inclined portion 7b must be in close contact with the packing material 4. The packing material 4 is hung by a locking part 6 which is formed on the upper part of the outer peripheral part 3 and is inclined inwardly, and an opening 5b of the can is positioned inside the locking part 6 and formed inside of this.

For this reason, the packing material 4 needs to be curved with a limited inclination angle in the diagonal direction so that it remains horizontal and the inwardly inclined inclined portion 7b also maintains its upright position without curving. Further, a fixing part 8 is provided below the outer peripheral part 3 and is recessed inwardly together with the body 5 of the can container and fixed thereto.

Since such a can container C can be manufactured by simply bringing the opening edge 7c into close contact with the lower side of the packing material 4, it is sufficient to make recesses in two places, the upper and lower, and no other machining is necessary.

Further, reference numeral 9 denotes a gap formed between the inner diameter portion 3a of the outer peripheral portion 3 and the inclined portion 7b, which facilitates the swelling of the packing material 4. The locking portion 6 for fixing the packing material 4 may be secured by caulking or punching without recessing the entire outer peripheral portion 3.

FIG. 4 shows an example of a modified structure of the packing material 4, in which the packing material 4 is formed into a receiving part 15 with a cross section 〓, the cylindrical part 4a is formed into the same body, and the can container C has an inclined part 7b.
The opening edge 7c of the opening edge 7c is brought into contact with the cylindrical portion 4a of the packing material 4 to achieve a good seal. 10 is a valve cylinder, 10a is an enlarged flange of the valve cylinder, 11 is a suction pipe, 12 is a valve stem having an orifice, 13 is a sealing gasket that supports opening and closing of the orifice, and 14 is a coil spring.

As described above, the present invention forms the uncurved inclined part 7b at the opening of the can container C, and also fixes the packing material 4 of the assembly cap 2 of the valve A by recessing the upper and lower parts of the outer periphery 3 of the cap 2. 6 and 8 are provided, the packing material 4 is supported horizontally by the upper fixed part 6, the inclined part 7b of the can container C is tightly adhered, and the lower fixed part 8 is fixed and installed. does not require any post-processing, and can be easily manufactured by simply inwardly inclining the inclined portion 7b to an appropriate degree, without causing molding defects or deteriorating manufacturing efficiency due to this, and also increases efficiency and improves airtightness. It has many effects, such as being able to hold it in place, and contributing to economic efficiency by not damaging the packing material due to linear contact.
