Abstract

A method of encapsulating content with calcium alginate membrane to form a capsule. The method includes embedding sodium alginate into a traditional gelatin ribbon used in gelatin encapsulation, adding calcium to a fill material, encapsulating the fill material, and then denaturing the gelatin in the shell. An exemplary use of this method is to form throwable paintballs; however, other products could be formed using this process. A paintball formed by this process is also disclosed.

Claims

exact text as granted — not AI-modified
I claim: 
     
         1 . A paintball comprising:
 a shell comprising:
 an alginate; 
 a gelatin; 
 a plasticizer; and 
 water; and 
   a fill material inside the shell comprising:
 polyethylene glycol; 
 calcium chloride; and 
 water. 
   
     
     
         2 . The paintball according to  claim 1 , wherein the shell comprises about 1.5 parts by weight of the alginate;
 about 111 parts by weight of the gelatin;   about 47 parts by weight of the plasticizer; and   about 130 parts by weight of the water.   
     
     
         3 . The paintball according to  claim 1 , wherein the shell comprises about 1.5 parts by weight of the alginate;
 about 111 parts by weight of the gelatin;   about 47 parts by weight of the plasticizer; and   a remainder the water.   
     
     
         4 . The paintball according to  claim 1 , wherein the fill material comprises:
 about 1.18 parts by weight of the calcium chloride;   about 10 parts by weight of the polyethylene glycol; and   about 12 parts by weight of the water.   
     
     
         5 . The paintball according to  claim 1 , wherein the fill material comprises:
 about  1 . 18  parts by weight of the calcium chloride;   about  10  parts by weight of the polyethylene glycol; and   a remainder the water.   
     
     
         6 . The paintball according to  claim 1 , wherein the plasticizer comprises glycerin. 
     
     
         7 . The paintball according to  claim 1 , wherein the shell further comprises a coloring agent. 
     
     
         8 . The paintball according to  claim 1 , wherein the shell further comprises a preservative. 
     
     
         9 . The paintball according to  claim 1 , wherein the fill material comprises a liquid. 
     
     
         10 . The paintball according to  claim 1 , wherein the alginate comprises calcium alginate. 
     
     
         11 . A paintball comprising:
 a calcium alginate shell;   and   a fill material inside the shell comprising:
 polyethylene glycol; 
 calcium chloride; and 
 water. 
   
     
     
         12 . The paintball according to  claim 11 , wherein the fill material comprises:
 about 1.18 parts by weight of the calcium chloride;   about 10 parts by weight of the polyethylene glycol; and   about 12 parts by weight of the water.   
     
     
         13 . The paintball according to claim  121 , wherein the fill material comprises:
 about 1.18 parts by weight of the calcium chloride;   about 10 parts by weight of the polyethylene glycol; and   a remainder the water.   
     
     
         14 . The paint ball according to  claim 11 , wherein the shell further comprises a coloring agent. 
     
     
         15 . The paintball according to  claim 11 , wherein the shell further comprises a preservative. 
     
     
         16 . The paintball according to  claim 11 , wherein the fill material comprises a liquid. 
     
     
         17 . A paintball comprising:
 a shell comprising:
 an alginate; 
 a gelatin; 
 a plasticizer; and 
 water; and 
   a fill material inside the shell.   
     
     
         18 . The paintball according to  claim 17 , wherein the shell comprises
 about 1.5 parts by weight of the alginate;   about 111 parts by weight of the gelatin;   about 47 parts by weight of the plasticizer; and   about 130 parts by weight of the water.   
     
     
         19 . The paintball according to  claim 17 , wherein the shell comprises
 about 1.5 parts by weight of the alginate;   about 111 parts by weight of the gelatin;   about 47 parts by weight of the plasticizer; and   a remainder the water.   
     
     
         20 . The paintball according to  claim 17 , wherein the alginate comprises calcium alginate.
