Composite compressible drink mix bag

Abstract

The composite compressible drink mix bag receives a drink mix therein. The composite compressible drink mix bag includes a water permeable, hollow compressible body defining a deformation axis, a first cap and a second cap. The compressible body has folding lines and is formed with two openings over each end thereof. The first and second caps are coupled to two ends of the compressible body and cover the openings respectively such that the compressible body is retractable along the deformation axis while maintains an overall shape. The two ends of the compressible body are retractable along the deformation axis to a storage state according to the volume of the drink mix before water is added or expandable to a relax state by the folding lines after water is added.

What is claimed is: 
     
         1 . A composite compressible drink mix bag for receiving a drink mix therein, the drink mix being in a first state before adding water while in a second state after adding water, comprising:
 a water permeable, hollow compressible body defining a deformation axis, a cross-section of the compressible body being perpendicular to the deformation axis, the compressible body having folding lines and formed with two openings over each end thereof;   a first cap; and   a second cap, the first and second caps coupled to two ends of the compressible body and covering the openings respectively, the compressible body and the first and second caps collectively defining a receiving space;   wherein when the drink mix is in the first state, the two ends of the compressible body are adjusted along the deformation axis according to the volume of the drink mix, when the drink mix is in the second state, the two ends of the compressible body are adjusted along the deformation axis to allow the drink mix for relaxing, and when the compressible body is immersed in the water, the two ends that are coupled to the first and second caps maintain an overall shape of the compressible body.   
     
     
         2 . The composite compressible drink mix bag according to  claim 1 , wherein the first cap includes a first cap body and a first ring, one end of the compressible body is coupled to one face of the first cap body while the first ring is connected to the other face of the first cap body, the second cap includes a second cap body and a second ring, and the other end of the compressible is coupled to one face of the first cap body while the second ring is connected to the other face of the second cap body. 
     
     
         3 . The composite compressible drink mix bag according to  claim 2 , wherein the two ends of the compressible body respectively bend toward the hollow interior and are coupled to the first and second cap bodies. 
     
     
         4 . The composite compressible drink mix bag according to  claim 2 , wherein the two ends of the compressible body respectively bend toward the exterior and are coupled to the first and second cap bodies. 
     
     
         5 . The composite compressible drink mix bag according to  claim 2 , wherein the first cap further includes a first supporting portion, the first supporting portion is arranged at the boundary in which the first cap body and the compressible body meet, the second cap further includes a second supporting portion, and the second supporting portion is arranged at the boundary in which the first cap body and the compressible body meet. 
     
     
         6 . The composite compressible drink mix bag according to  claim 5 , wherein the first and the second supporting portions are aligned, and when the compressible body is compressed, the first and the second supporting portions are in contact. 
     
     
         7 . The composite compressible drink mix bag according to  claim 6 , wherein the first supporting portion is substantially perpendicular to the first cap body, and the second supporting body is substantially perpendicular to the second cap body. 
     
     
         8 . The composite compressible drink mix bag according to  claim 1  further comprising an edible water proof adhesive, the first and the second caps attached to the two ends respectively via the edible water proof adhesive. 
     
     
         9 . The composite compressible drink mix bag according to  claim 1  further comprising a string and a tap, the string connecting the second cap and the tag. 
     
     
         10 . The composite compressible drink mix bag according to  claim 1 , wherein the deformation axis is substantially parallel to a vertical line.
