Portable bathtub for maintaining the temperature of water used for bathing

Abstract

A portable bathtub for maintaining the temperature of the water used for bathing. The bathtub is comprised of an outer tub comprising an upper rim portion and a receptacle portion, as well as at least a first drain opening and an outlet; and, an inner tub comprising an upper rim portion and a receptacle portion, as well as a second drain opening. The inner tub is positioned within the outer tub such that the receptacle portion of the inner tub is spaced apart a predetermined distance from the receptacle portion of the outer tub, creating a hollow space between the two tubs. The upper rim portion of the inner tub is removably connected to the upper rim portion of the outer tub. At least one inlet is formed between the upper rim portion of the inner tub and the upper rim portion of the outer tub, for introducing a heated liquid to the hollow space. The first drain opening is for allowing a heated liquid introduced to the hollow space to exit therefrom, and the second drain opening is disposed within the outlet for allowing the water used for bathing, when contained in the receptacle portion of the inner tub, to exit through the second drain opening and the outlet.

1 . A portable bathtub for at least maintaining the temperature of the water used for bathing, said bathtub comprised of:

       2 . The portable bathtub according to  claim 1 , wherein a coupling device removably connects the upper rim portion of the inner tub to the upper rim portion of the outer tub. 
   
   
       3 . The portable bathtub according to  claim 2 , wherein the coupling device comprises a clip affixed to the inner tub, and removably affixable to the outer tub. 
   
   
       4 . The portable bathtub according to  claim 2 , wherein the coupling device comprises a clip affixed to the outer tub, and removably affixable to the inner tub. 
   
   
       5 . The portable bathtub according to  claim 2 , wherein the coupling device comprises an elastic belt positioned along the outer perimeter of said bathtub, between the upper rims, wherein said belt comprises an integral clip mechanism for fastening upper rims to each other. 
   
   
       6 . The portable bathtub according to  claim 1 , wherein the inlet comprises a cover for selectively opening and closing said inlet. 
   
   
       7 . The portable bathtub according to  claim 6 , wherein the cover comprises a plurality of ventilation openings. 
   
   
       8 . The portable bathtub according to  claim 1 , further comprising a plug for selectively opening and closing the first drain opening. 
   
   
       9 . The portable bathtub according to  claim 1 , further comprising a plug for selectively opening and closing the outlet and second drain opening. 
   
   
       10 . The portable bathtub according to  claim 1 , wherein the outer tub comprises a transparent portion for allowing the amount of water contained in the hollow space to be visually detected. 
   
   
       11 . A portable bathtub system comprising:
 a. the portable bathtub according to  claims 1 - 10 ; and,   b. a foldable stand for mounting said bathtub thereon.   
   
   
       12 . The bathtub system according to  claim 11 , wherein the stand comprises two u-shaped components, wherein each component comprises two legs and a shoulder for joining integrally joining said legs together, wherein one leg of one components is pivotally coupled with one leg of the other component for selectively rotating between a collapsed position and an open position. 
   
   
       13 .
