Description
- 1. Field of the Invention
- The present invention relates to a rubber liquid spray lid having an embedded pumping device. More particularly, the present invention relates to a rubber liquid spray lid having an embedded pumping device for spraying liquid when pumping pressure is applied thereto, the rubber liquid spray lid being capable of being easily manufactured in a relatively short time at low cost because a lid thereof and a valve installed in the lid have a simple structure that can be made through an extrusion method, having an optimum spray distance, seldom breaking when it is accidentally dropped by a user because it is made of a material that is flexible and has amorphous characteristic, being capable of preventing the lifespan of liquid from decreasing because it is made of a material containing an antioxidant, that is, it can prevent liquids such as polymers, petroleum products, oils, soaps, etc. from being oxidized, and having high reliability and quality because cutting-lines serving as spray nozzles are formed simultaneously and uniformly through an extrusion method.
- 2. Description of the Related Art
- Generally, liquid containers for holding liquid such as cosmetics therein are classified into general vessels and spray-lid-equipped vessels. The spray-lid-equipped vessel comprises a vessel for holding liquid therein and a liquid spray lid integrated with a pumping device that enables liquid such as a cosmetic held in the vessel to be sprayed through a nozzle formed in a lid when a user pushes the top of the lid.
- The lid integrated with a pumping device into a single body generally comprising a nozzle cap installed at the top of a liquid vessel, a nozzle button installed on the top of the nozzle cap, a cylinder installed under the nozzle cap, an upper plunger and a lower plunger installed to penetrate the nozzle cap, a spring installed in the cylinder and a ball combined with the spring.
- However, the conventional liquid spray lid combined with a pumping device has a very complicated structure, so that it takes a long time to manufacture and is expensive, thereby imposing economical burdens on manufacturers and customers.
- Further, before liquid in a vessel is sprayed outside, the liquid must enter the cylinder first. Accordingly, while the liquid is present in the cylinder, the liquid is in contact with a metal spring, so that the liquid is deteriorated by metal ions generated from the metal spring, and rust components in the metal spring cause harm to user's health.
- For the above-described reason, in order to solve the above-mentioned problems, a variety of liquid-spray lids integrated with a pumping device has been developed.
- Among such recently developed liquid-spray lids, one exemplary liquid spray lid has been developed by the applicant of the present invention. The exemplary liquid spray lid having a pumping device comprises a first valve installed at an opening of a liquid vessel that contains liquid therein, for allowing the liquid in the liquid vessel to be discharged out of the liquid vessel and for preventing the liquid from flowing back into the liquid vessel, a pressurizing unit which is made of a flexible material and forms a pressurizing space outside the first valve, and a second valve installed in the pressurizing unit for allowing liquid in the pressurizing space to be discharged out of the pressurizing space and allowing liquid to be introduced into the pressurizing space.
- Either one of the first and second valves is curved and extends outside the lid, and further has a projection with a cutting-line serving as a nozzle. The projection is made of a flexible material so that the cutting-line serving as a nozzle is elastically opened and closed.
- The above-described lid having an embedded pumping device has advantages in that it can be relatively easily manufactured because it has a relatively simple structure. The above-described lid has a further advantage in that it can effectively supply and spray liquid by using the first and second valves. However, it still has disadvantages encountered when using the conventional liquid spray lid even though it has a relatively improved pumping ability. That is, since it still uses a metal spring, the liquid is deteriorated after the lid has been used for a long time, and rust components in the metal spring cause harm to a user's health.
- Further, since the cutting lines (nozzles) of the first and second valves for supplying and spraying liquid are made after the features of the first and second valves are formed, there is no consistency between the amounts of supplied and sprayed liquid, so that the reliability and quality of the liquid spray lid is not good.
- Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide a rubber liquid spray lid having an embedded pumping device for spraying liquid when pumping pressure is applied thereto, the rubber liquid spray lid being capable of being easily manufactured in a relatively short time at low cost because a lid and a valve installed in the lid have a simple structure that can be made through an extrusion method, having an optimum spray distance, seldom breaking when it is accidentally dropped by a user because it is made of a material that is flexible and has an elastic structure, being capable of preventing the lifespan of liquid from decreasing because it is made of a material containing an antioxidant, that is, it can prevent a liquid such as polymers, petroleum products, oils, soaps, etc. from oxidizing, and having high reliability and quality because cutting-lines serving as spray nozzles are simultaneously and uniformly formed through an extrusion method.
- In order to achieve the above object, according to one aspect of the present invention, there is provided a rubber liquid spray lid, comprising a lid, serving as a pushing member, having a first valve installation groove for receiving and fixing a first valve therein, formed on an outer circumferential surface thereof, a coupling hole connected to the first valve installation groove and formed in a center portion of a lower part thereof for enabling the lid to be fixed to an opening of a liquid vessel, a pumping force generation variable space formed in a center portion thereof for easily generating a pumping force needed to spray liquid, and a plurality of first air inlet holes formed along the circumferential edge of a lower end part thereof for allowing external air to be introduced thereinto; a first valve fixed in the first valve installation groove of the lid, having a spray hole at a front end thereof, through which liquid transferred from the liquid vessel is sprayed because the spray hole is elastically opened and closed when pumping pressure is applied to the top of the lid, and having a protrusion at a rear end thereof for enabling the first valve to be securely fixed to the first groove; and a middle valve installed to be connected to the coupling hole formed in the lid, and comprised of a connecting and fixing part coupled to a first end of a pipe vertically disposed in the liquid vessel and having a second end dipped in liquid in the liquid vessel, for transferring liquid held in the vessel to the lid during pumping, a cover provided to the outer circumferential surface of the connecting and fixing part for preventing the liquid from leaking from the liquid vessel, the cover and the connecting and fixing part being integrated into a single body, and a stepped platform installed above and coupled to the cover and comprised of a flat portion having a plurality of second air inlet holes connected to the first air inlet holes so that external air can be introduced into the lid during pumping, and an elevated portion provided on the flat portion, the elevated portion being inserted into and fixed in the coupling hole and providing a second valve installation groove inside thereof, and a second valve installed in the second valve installation groove defined by the elevated portion of the stepped platform, the second valve allowing the liquid to be transferred from the liquid vessel to the pumping force generation variable space and preventing the liquid in the pumping force generation variable space from flowing back into the liquid vessel.

-
FIG. 7 illustrates the operational state of the rubber liquid spray lid having an embedded pumping device according to the embodiment of the present invention. - Referring to
FIG. 7 , the liquid spray lid according to the present invention sprays liquid from a liquid vessel when a user lightly pushes the top of therubber lid 10. - If a user pushes the top of the
rubber lid 10 once, the center of therubber lid 10 is depressed by the pushing force, and is then restored to its original shape. When therubber lid 10 is restored to its original shape, a pumping force is generated in the pumping force generationvariable space 13 provided in the center of therubber lid 10. - Further, while the
depressed rubber lid 10 is restored, external air is introduced into therubber lid 10 through the first air inlet holes 14 connected to the second air inlet holes 46 provided in the steppedplatform 47 of themiddle valve 40. Accordingly, restoration of thelid 10 can progress smoothly, while helping generate the pumping force. - The pumping force generated in the above-described manner increases the inner pressure in the
liquid vessel 30 holding the liquid therein. - As the inner pressure of the
liquid vessel 30 increases, the liquid in theliquid vessel 30 comes to be sprayed outside via thepipe 41 connected to themiddle valve 40, thesecond valve 20 b, the pumping force generationvariable space 13, and thefirst valve 20 a. - Accordingly, the liquid spray lid according to the present invention not only has the same or equivalent ability and function as the conventional liquid spray lid having an embedded pumping device, which sprays a predetermined amount of liquid from a liquid vessel through a nozzle when a pushing force is applied to a push button, i.e. a lid, but also has a relatively simple structure. Due to such reason, the liquid spray lid according to the present invention can be easily manufactured in a short time and at low cost. That is, since the liquid spray lid having an embedded pumping device can be manufactured at low cost due to the simple structure, manufacturers and consumers thereof can enjoy economical benefits.
- Further, since all of the elements of the liquid spray lid according to the present invention are made of a flexible amorphous rubber containing an antioxidant, the liquid spray lid according to the present invention is able to prevent a liquid such as polymer, petroleum products, oils, soaps etc., which are apt to be easily oxidized, from being oxidized. As a result, the liquid spray lid according to the present invention prevents the lifespan of a liquid product from decreasing.
- The
rubber lid 10, thefirst valve 20 a, thesecond valve 20 b and themiddle valve 40 are made of a material having the composition shown in Table 1 and are manufactured through an extrusion method.TABLE 1 Content Substance PHR WT % Natural Resin 50.00 41.61 Paraffin 35.00 29.13 Antioxidant 0.15 0.12 Synthetic Rubber 20.00 16.65 Polypropylene 15.00 12.49 Total 120.15 100.00 - Natural resin, i.e. base resin, is a general resin present in nature. Natural resin is not a single substance, but may contain a plurality of substances. Natural resin can be obtained during a petroleum refining process. Each of the rubber lid 10 (pushing member), the first nozzle 20, and the
second nozzle 30 contains 41.61% natural resin. - Paraffin oil is contained in heavy oil, and is obtained by cooling heavy oil to generate precipitates and filtering the heavy oil with precipitates while applying pressure thereto. Each of the rubber lid 10 (pushing member), the first nozzle 20 and the
second nozzle 30 contains 29.13% paraffin oil. - The antioxidant is an additive for preventing oxidation. Each of the rubber lid 10 (pushing member), the first nozzle 20 and the
second nozzle 30 contains 0.12% antioxidant. - The synthetic rubber is styrene butadiene rubber, and is made by copolymerizing styrene and butadiene. The rubber lid 10 (pushing member), the first nozzle 20 and the
second nozzle 30 contain 16.65% synthetic rubber. - The polypropylene can be extrusion-molded, and can be made to have a variety of colors, or can be transparent. The rubber lid 10 (pushing member), the first nozzle 20 and the second 10
nozzle 30 have 12.49% polypropylene. - As described above, each of the rubber lid 10 (pushing member), the first nozzle 20, and the
second nozzle 30 comprises natural resin, paraffin, antioxidant, synthetic rubber and polypropylene. Accordingly, the liquid spray lid according to the present invention has amorphous crystal structure and greater flexibility than the conventional liquid spray lid having a metal spring because it is made of material containing natural resin, and can prevent oxidation of a liquid such as polymer, petroleum products, oils, soaps, etc. because the lid is made of a material containing antioxidant. Further, since the lid is made of a material containing polypropylene, the liquid spray lid according to the present invention can be made to have a variety of colors, or can be transparent. - Further, since the liquid spray lid according to the present invention is made of a material containing the above-mentioned substances, hazardous substances that can cause harm to a user's health can be prevented from being added to liquid after use for a long time. Still further, because nozzles, i.e. cutting lines, of the
first valve 20 a and thesecond valve 20 b are formed during an extrusion process, the liquid spray lid according to the present invention has reliability and quality. - Alternatively, as shown in
FIGS. 6A to 6F, the shapes of thefirst valve 20 a and thesecond valve 20 b may be diversely modified. - The shapes of the first and
second valves liquid vessel 30. That is, the shapes of the first andsecond valves liquid vessel 30. - The above-described liquid spray lid having an embedded pumping device according to the present invention has the following advantages. First, the liquid spray lid having an embedded pumping device for spraying a liquid using a pumping force generated when a pumping pressure is applied comprises a rubber lid and valves installed in and connected to the rubber lid, the rubber lid and the valves having a simple structure that can be made through an extrusion method. Further, the liquid spray lid having an embedded pumping device according to the present invention has a structure that can provide an optimized spraying distance. Still further, the liquid spray lid having an embedded pumping device according to the present invention is made of a flexible rubber. Accordingly, the liquid spray lid having an embedded pumping device according to the present invention can be easily manufactured in a relatively short time at low cost. Further, the liquid spray lid having an embedded pumping device according to the present invention does not break when it is accidentally dropped by a user because it is made of a flexible amorphous material. Still further, since the liquid spray lid having an embedded pumping device according to the present invention is made of a material containing an antioxidant, it does not decrease the given lifespan of liquid such as polymer, petroleum products, oils, soaps etc., because it prevents oxidation of the liquid. Yet still further, because the liquid spray lid having an embedded pumping device according to the present invention is made through an extrusion method, and because the cutting lines (nozzles) of the first and second valves are formed during the extrusion process, the reliability and product quality of the liquid spray lid having an embedded pumping device according to the present invention are guaranteed.
