Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The current invention relates to a green nozzle, it specifically relates to a simplest component assembly where the liquid such as lotion or perfume in the container won't change its quality, through the simplest component and assembly to achieve the ejection function of lotion or perfume and enhance the economic effectiveness.
2. Description of the Prior Art
In the prior art nozzle 1 structure, as shown in FIG. 1, comprising of a pressing body 11 installed on tooth cover 12, the upper part of tube 13 installs at and penetrates the holes 121 of tooth cover 12 in order to be connected to the pressing body 11, the lower part of the tube 13 is installed and penetrated with a tube cover 14 to be connected to a base tube 15, meanwhile, the correlating small holes 151 installed at both sides of the base tube 15 are just exactly covered by the tube cover 14, meanwhile, a spring 16 is installed at the lower part of the base tube 15, a steel ball 17 is placed at the lower part of the spring 16, they are installed in the cylinder 18 which shrinks its hole diameter from top to the bottom, therefore, the upper edge end of the cylinder 18 is connected to the bottom edge of the slot hole 121 of the tooth cover 12, moreover, the lower end of the cylinder 18 is connected to a straw 19.
From the above descriptions, the user first press on the pressing body 11 to let the air in the container immediately eject from the nozzle opening 111 of the pressing body 11, in the mean time, the siphon effect will bring the liquids such as lotion or perfume from the straw 19 with the air into the cylinder body 18, at this moment, due to the spring force of the spring 16, the bottom of the tube base 15 will press on the steel ball 17 and the steel ball 17 will block the hole of the cylinder 18, furthermore, make a gap between the tube base 15 and tube cover 14 and make the lotion or perfume contained in the cylinder 18 can go along the space of the gap to the small holes 151 on the two sides of the outer edges of the base tube 15 and penetrate into the base tube 15, then through the tube 13, the lotion or perfume will be ejected along with air out from the nozzle opening 111 of the pressing body 11, when the pressing body 11 is let go, the liquids such as lotion or perfume remained in the cylinder 18 will then go back to the container.
Continued from the above descriptions, in the prior art structure of nozzle 1, although the function of the ejection of lotion or perfume still can be reached, since the spring 16, steel ball 17 are made up of metallic material and are installed inside the cylinder 18, they could cause chemical change for the lotion and perfume in the container due to the long time contact to the metallic spring 16 and steel ball 17, which in turn could deteriorate the quality of the lotion or perfume and harm the customers, but if the chemically changed lotion or perfume are dumped away, they will cause environmental contamination due to difficulty in dilution and recycling; moreover, since the structure design of the prior art nozzle 1 has so many components, it cause an increase in the material cost, its difficulty in assembly and disassembly further reduces practical economic effectiveness.
Therefore, to solve the drawback and inconvenience in the prior art nozzle, the inventor of the current invention thus developed a more practical structure for green nozzle which can have a more wide-spread use in the industry and take into account environmental issue as well.
