Diaphragm-style bottle pump

Abstract

A diaphragm bottle pump system for dispensing a personal care product includes a bottle, a pump body, and a plurality of valves. The bottle holds the product. Further, the pump body includes a lower pump body and an upper pump body that define a diaphragm chamber therebetween that is acted on by a diaphragm. A first valve allows the product to pass from the bottle to the diaphragm chamber and prevents the product from passing to the bottle from the diaphragm chamber. A second valve allows the product to pass from the diaphragm chamber to an outside of the system and prevents the product from passing to the diaphragm chamber from the outside of the system. Additionally, a third valve allows air to pass from the outside of the system to the bottle and prevents the air from passing to the outside of the system from the bottle.

1 . A diaphragm bottle pump system to dispense a personal care product, comprising:
 a bottle that holds the product;   a lower pump body attached to the bottle and having an air inlet extending through the lower pump body;   an upper pump body attached to the lower pump body and having a diaphragm positioned on a top part of the upper pump body, the lower pump body and the upper pump body defining a diaphragm chamber therebetween;   a first valve that passes the product from the bottle to the diaphragm chamber when the diaphragm returns to an original position from a depressed position and that prevents the product from passing to the bottle from the diaphragm chamber;   a second valve that passes the product from the diaphragm chamber to an outside of the system when the diaphragm is moved from the original position to the depressed position and that prevents the product from passing to the diaphragm chamber from the outside of the system; and   a third valve that passes the product from the outside of the system to the bottle when the diaphragm returns to the original position from the depressed position and that prevents the air from passing to the outside of the system from the bottle.   
     
     
         2 . The diaphragm pump system according to  claim 1 , wherein the second valve is a duckbill valve. 
     
     
         3 . The diaphragm pump system according to  claim 1 , wherein the second valve is a flapper valve. 
     
     
         4 . The diaphragm pump system according to  claim 1 , wherein the third valve is a duckbill valve. 
     
     
         5 . The diaphragm pump system according to  claim 1 , wherein the third valve is a flapper valve. 
     
     
         6 . The diaphragm pump system according to  claim 1 , wherein the first valve is an umbrella valve. 
     
     
         7 . The diaphragm pump system according to  claim 1 , further comprising:
 the personal care product held in the bottle.   
     
     
         8 . A diaphragm pump for dispensing a personal care product, comprising:
 a lower pump body having an air inlet extending through a side wall of the lower pump body;   an upper pump body attached to the lower pump body and having a diaphragm positioned on a top part of the upper pump body, the lower pump body and the upper pump body defining a diaphragm chamber therebetween;   a first valve that passes the product from a bottle attached to the lower pump body to the diaphragm chamber when the diaphragm returns to an original position from a depressed position and that prevents the product from passing to the bottle from the diaphragm chamber;   a second valve that passes the product from the diaphragm chamber to an outside of the system when the diaphragm is moved from the original position to the depressed position and that prevents the product from passing to the diaphragm chamber from the outside of the system; and   a third valve that passes the product from the outside of the system to the bottle when the diaphragm returns to the original position from the depressed position and that prevents the air from passing to the outside of the system from the bottle.   
     
     
         9 . The diaphragm pump according to  claim 8 , wherein the second valve is a duckbill valve. 
     
     
         10 . The diaphragm pump according to  claim 8 , wherein the second valve is a flapper valve. 
     
     
         11 . The diaphragm pump according to  claim 8 , wherein the third valve is a duckbill valve. 
     
     
         12 . The diaphragm pump according to  claim 8 , wherein the third valve is a flapper valve. 
     
     
         13 . The diaphragm pump according to  claim 8 , wherein the first valve is an umbrella valve. 
     
     
         14 . A method of dispensing a personal care product, comprising:
 holding the product in a bottle attached to a diaphragm pump including a diaphragm in an original position on a top of the diaphragm pump;   pressing the diaphragm a first time such that the diaphragm is changed from the original position to a depressed position to expel air held in a diaphragm chamber to an outside of the diaphragm pump through a first valve;   preventing the expelled air from returning to the diaphragm chamber from the outside of the diaphragm pump through the first valve;   releasing the diaphragm a first time such that the diaphragm returns to the original position from the depressed position to create a reduced pressure in the diaphragm chamber;   drawing product from the bottle to the diaphragm chamber through a second valve;   preventing the drawn product from returning to the bottle from the diaphragm chamber through the second valve;   during the drawing the product, drawing new air from an outside of the bottle into the bottle through a third valve;   preventing the drawn air and the product in the bottle from passing through the third valve to the outside of the bottle through the third valve; and   pressing the diaphragm a second time such that the diaphragm is changed from the original position to the depressed position to expel the drawn product held in the diaphragm chamber to the outside of the diaphragm pump through the first valve.   
     
     
         15 . The dispensing method according to  claim 14 , wherein the releasing the diaphragm the first time includes biasing the diaphragm with a spring positioned below the diaphragm such that the diaphragm returns to the original position from the depressed position. 
     
     
         16 . The dispensing method according to  claim 14 , wherein the first valve is a duckbill valve. 
     
     
         17 . The dispensing method according to  claim 14 , wherein the first valve is a flapper valve. 
     
     
         18 . The dispensing method according to  claim 14 , wherein the second valve is a duckbill valve. 
     
     
         19 . The dispensing method according to  claim 14 , wherein the second valve is a flapper valve.
