FIG. 11 shows, as the content supply means 4, a valve head 4a having an opening 4c connected to the ejection port of the hollow stem 1a, and a base 1 having a radial groove on the back surface which is fitted at the tip end surface of the nozzle body 2. This is a structure in which body-shaped nozzle tips 2a are provided, and by combining these, an injection path p is formed between the nozzle tips 2a to uniformly distribute and supply the contents to each nozzle tip 2a.

In the container having such a structure, the nozzle body 2 and the nozzle tip 2a are combined separately, but the injection path p is formed by directly joining the valve head 4a. Like FIG. 10, the flow dividing plate 4b as shown in FIG. 9 can be omitted, which is useful for reducing the size.

FIG. 12 shows still another example of the container according to the present invention. In this example, a valve head 4a having an opening 4c connected to a spout of a hollow stem 1a and a radial groove 4j (similar to that shown in FIG. 4a and distribute the contents almost uniformly to each nozzle tip 2a.
This is a structure having a sheet-like packing 4q with an opening forming an injection path p so as to supply the gas.

In the container having such a structure, it is necessary to provide a radial groove 4j for forming the injection path p in the valve head 4a. There is an advantage that the dimension L can be made smaller as compared with those shown in FIGS. 10 and 11, and the injection state of the contents is not limited to that shown in FIG.
There is no difference from the container shown in FIG.

The valve head 4a shown in FIG.
FIG. 13 is an exploded perspective view of the nozzle tip 2a integrated with the base and the base.
FIG. 14 is an exploded perspective view of the valve head 4a and the sheet packing 4q shown in FIG.

FIG. 15 shows an example in which the nozzle having the structure shown in FIG. 10 is applied to a container having a pressure accumulating pump T instead of the aerosol type container. According to the present invention, even in such a container, the contents filled in the container main body 1 can be uniformly sprayed over a wide range and adhere to an object to be sprayed such as cotton.

FIG. 16 shows an example of a trigger-type container provided with a nozzle which is integrally formed by engaging the nozzle body 2 with the base member 3 by undercut. Such a container can uniformly spray the contents over a wide range by a single towing operation by the trigger M.

FIGS. 10 to 16 show the structure having no flow dividing plate 4b as shown in FIG. 1, but in this case, the nozzle body 1 of the nozzle tip 2a is formed.
17 is located in the center of the hollow stem 1a as shown in FIG. 17 directly facing the ejection port, the contents are preferentially supplied to the nozzle tip 2a. In the case where such a nozzle tip is provided, it is necessary to devise the flow path r of the projection 2d of the nozzle tip 2a with respect to the opening 4c as shown in FIGS. .

As a material constituting the aerosol container, a resin such as plastic can be used, but a metal material can also be used, which is appropriately changed depending on the contents to be filled.

[0044]

According to the present invention, the contents in a container can be sprayed over a wide area almost uniformly into a hand, foot, cotton, or the like by a single operation. In addition, it is easy to use because one-foot or one-hand operation is possible.
