Drainable cap for invertible containers

Abstract

A system is described for storing liquids. The system comprises a cap configured to couple to a container. The cap comprises a base surface configured to provide a base for a coupled container; a flip-open lid positioned to enable access to an interior of a coupled container; a first cavity having a floor defined by a portion of the cap and a sidewall defined by a portion of the cap; and a drainage port sized to enable water to drain from the first cavity. By providing one or more drainage ports for the hollow portions of invertible container caps, the tendency of water to pool and stagnate within the caps can be reduced. This can reduces the growth of harmful mold in showers.

1 . A system for storing liquids, the system comprising:
 a cap configured to couple to a container, the cap comprising:
 a base surface configured to provide a base for a coupled container; 
 a flip-open lid positioned to enable access to an interior of a coupled container; 
 a first cavity having a floor defined by a portion of the cap and a sidewall defined by a portion of the cap; and 
 a drainage port sized to enable water to drain from the first cavity. 
   
   
   
       2 . The system of  claim 1  wherein the first cavity comprises:
 a ramp configured to direct water toward the drainage port.   
   
   
       3 . The system of  claim 1  wherein the drainage port is disposed on the base surface. 
   
   
       4 . The system of  claim 1  wherein the base surface comprises:
 a water channel configured to allow water to pass from the drainage port to an edge of the base surface when the base surface abuts an approximately flat surface.   
   
   
       5 . The system of  claim 1  wherein the drainage port is disposed on the flip-open lid. 
   
   
       6 . The system of  claim 1  wherein the flip-open lid comprises:
 the entirety of the base surface.   
   
   
       7 . The system of  claim 1  wherein the flip-open lid comprises:
 a portion, less than the entirety, of the base surface.   
   
   
       8 . The system of  claim 1  wherein the first cavity has a top side defined by a portion of a coupled container. 
   
   
       9 . The system of  claim 1  wherein the cap further comprises:
 a second cavity having a floor defined by a portion of the cap and a top side defined by a portion of the cap.   
   
   
       10 . The system of  claim 1  wherein the first cavity has a top side defined by a portion of the cap. 
   
   
       11 . The system of  claim 1  further comprising:
 a container coupled to the cap.   
   
   
       12 . The system of  claim 11  wherein the container comprises at least one selected from the list consisting of:
 a flexible-sided bottle and a flexible-sided tube.   
   
   
       13 . The system of  claim 11  further comprising:
 a liquid within the container.   
   
   
       14 . The system of  claim 1  wherein the drainage port is disposed on the sidewall of the cavity. 
   
   
       15 . The system of  claim 1  wherein the drainage port is disposed near an intersection of a sidewall of the cap and the base surface. 
   
   
       16 . The system of  claim 1  wherein the cap further comprises:
 a plurality of drainage ports.   
   
   
       17 . A system for storing liquids, the system comprising:
 a flexible-sided container;   a cap coupled to the container, the cap comprising:
 a base surface configured to provide a base for the container; 
 a flip-open lid positioned to enable access to an interior of the container; 
 a first cavity having a floor defined by a portion of the cap and a sidewall; and 
 a plurality of drainage ports sized to enable water to drain from the cavity. 
   
   
   
       18 . The system of  claim 17  wherein the cavity is further defined on a top side by a portion of the container, wherein the flip-open lid comprises a portion, less than the entirety, of the base surface, wherein the cavity sidewall is defined by a sidewall of the cap, and wherein at least one of the plurality of drainage ports is disposed on the base surface. 
   
   
       19 . The system of  claim 17  wherein the cavity is further defined on a top side by a portion of the cap, wherein the flip-open lid comprises the entirety of the base surface, wherein the cavity sidewall is defined by a portion of the flip-open lid, and wherein at least one of the plurality of drainage ports is disposed near an intersection of the sidewall of the cavity and the base surface.
