Abstract

A container is disclosed comprising a lower container that is open at a top end thereof, the top end terminating with a first attachment means. An upper container is open at a bottom end thereof and at a top end thereof. The bottom end of the upper container terminates with a second attachment means that is adapted to cooperate with the first attachment means of the lower container. The top end of the upper container terminates with a third attachment means. A closure is adapted to selectively seal the open top end of the upper container, the closure means further including a fourth attachment means adapted to cooperate with the third attachment means of the top end of the upper container. In use, the upper and lower containers may be selectively mutually attached to form the container. The upper and lower containers may be mutually detached at the first and second attachment means to facilitate washing thereof.

Claims

exact text as granted — not AI-modified
1 . A container comprising:
 a lower container open at a top end thereof, the top end terminating with a first attachment means;   an upper container open at a bottom end thereof and at a top end thereof, the bottom end terminating with a second attachment means adapted to cooperate with the first attachment means of the lower container, the top end terminating with a third attachment means; and   a closure means adapted to selectively seal the open top end of the upper container and having a fourth attachment means adapted to cooperate with the third attachment means of the top end of the upper container;   whereby the upper and lower containers may be selectively mutually attached to form a container open only at the top end of the upper container, the closure means allowing selective opening and closing of the container, and whereby the upper and lower containers may be detached to facilitate washing thereof.   
   
   
       2 . The container of  claim 1  wherein the first attachment means of the lower container and the second attachment means of the bottom end of the upper container are each cooperating screw threads. 
   
   
       3 . The container of  claim 1  wherein the third attachment means at the top end of the upper container and the fourth attachment means of the closure means are each cooperating screw threads. 
   
   
       4 . The container of  claim 1  wherein the upper and lower containers generally each contain the same volume. 
   
   
       5 . The container of  claim 1  wherein the lower container contains generally twice the volume of the upper container. 
   
   
       6 . The container of  claim 1  wherein the upper container contains generally twice the volume of the lower container. 
   
   
       7 . The container of  claim 1  wherein the first attachment means of the lower container and the second attachment means of the bottom end of the upper container are each cooperating friction-fit snap means. 
   
   
       8 . The container of  claim 1  wherein the third attachment means at the top end of the upper container and the fourth attachment means of the closure means are each cooperating friction-fit snap means. 
   
   
       9 . A container comprising:
 a lower container open at a top end thereof, the top end terminating with a screw thread;   an upper container open at a bottom end thereof and at a top end thereof, the bottom end terminating with screw thread adapted to cooperate with the screw thread of the lower container, the top end terminating with a screw thread; and   a closure means adapted to selectively seal the open top end of the upper container and having a screw thread adapted to cooperate with the screw thread of the top end of the upper container;   whereby the upper and lower containers may be selectively mutually attached to form a container open only at the top end of the upper container, the closure means allowing selective opening and closing of the container, and whereby the upper and lower containers may be detached to facilitate washing thereof.   
   
   
       10 . The container of  claim 9  wherein the upper and lower containers generally each contain the same volume. 
   
   
       11 . The container of  claim 9  wherein the lower container contains generally twice the volume of the upper container. 
   
   
       12 . The container of  claim 9  wherein the upper container contains generally twice the volume of the lower container. 
   
   
       13 . The container of  claim 1  wherein a height of the lower container is less than 1.5 times the diameter of the open top end thereof. 
   
   
       14 . The container of  claim 1  wherein a height of the upper container is less than 1.5 times the diameter of the open bottom end thereof.
