Rubber liquid spray lid having embedded pumping device

Abstract

Disclosed is a rubber liquid spray lid having an embedded pumping device comprising a rubber lid serving as a pushing member and having a plurality of first air inlet holes and a pumping force generation variable space therein, a first valve received in a first valve groove formed in the rubber lid for allowing liquid in the pumping force generation variable space to be sprayed outside, and a middle valve connected to the first valve and installed in a center portion of a lower part of the rubber lid for allowing liquid in a liquid vessel to be transferred from the liquid vessel to the pumping force generation variable space and for preventing the liquid in the pumping force generation variable space from flowing back into the liquid vessel, wherein the middle valve comprises a connecting and fixing part connected to a first end of a pipe having a second end dipped in liquid in the liquid vessel, a cover part provided to the circumferential outer surface of the connecting and fixing part, and a stepped platform having a plurality of second air inlet holes connected to the first air inlet holes and an elevated portion for providing a second valve installation groove therein, so that a second valve is installed in the second valve installation groove.

1 . A liquid spray lid having an embedded pumping device to be installed on a liquid vessel for spraying a predetermined amount of liquid held in the liquid vessel when pumping pressure is applied to a pushing member thereof, comprising: 
 a lid, serving as a pushing member, having a first valve installation groove for receiving and fixing a first valve therein, on an outer circumferential surface thereof, a coupling hole  12  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 onto a liquid vessel, a pumping force generation variable space formed in a center portion thereof for enabling easy generation of a pumping force needed to spray liquid, and a plurality of first air inlet holes along a 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 portion thereof for enabling the first valve to be securely fixed to the first valve installation 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 pipe such that the connecting and fixing part is fixed to an outer circumferential surface of a first end of a pipe vertically disposed in the liquid vessel and having a second end immersed in liquid in the liquid vessel for transferring the liquid held in the liquid vessel to the lid during pumping, a cover fixed to an outer circumferential surface of the connecting and fixing part for preventing the liquid in the liquid vessel from leaking, the cover and the connecting and fixing part being integrated into a single body, and a stepped platform installed above and connected 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 able to be inserted into and fixed in the coupling hole and having a second valve installation groove therein for receiving a second valve therein, and the second valve being installed in the second valve installation groove for allowing the liquid to be transferred from the liquid vessel to the pumping force generation variable space and for preventing liquid in the pumping force generation variable space from flowing back into the liquid vessel.    
   
   
       2 . The rubber liquid spray lid according to  claim 1 , wherein the first valve, the second valve, and the middle valve are made of a flexible rubber comprising 41.61% natural resin, 29.13% paraffin, 0.12% antioxidant, 16.65% synthetic rubber, and 12.49% polypropylene, and are made through an extrusion method.
