Piercing cap assembly

Abstract

An assembly is configured to secure to a spout of a bag in order to pierce the bag to allow fluid to flow therethrough. The assembly includes an adaptor configured to secure to the spout. The adaptor includes an annular base connected to a cap-connection tube. The assembly also includes a cap that is rotatably secured to the cap-connection tube. The cap is configured to rotate about the adaptor in order to slice a fluid opening through the bag.

         5 . The assembly of  claim 4 , wherein the chamfered opening also sealingly engages a portion of the cap as the cap is mated with the adaptor. 
     
     
         6 . The assembly of  claim 1 , wherein the annular base includes a plurality of tactile members. 
     
     
         7 . The assembly of  claim 1 , wherein the cap includes a piercing member having a cutting tooth followed by at least one smooth fin. 
     
     
         8 . The assembly of  claim 7 , wherein the at least one smooth fin is configured to push a cut flap of the bag out of a cutting envelope of the cutting tooth so that the cut flap remains connected to the bag. 
     
     
         9 . The assembly of  claim 1 , wherein the cap includes a nozzle. 
     
     
         10 . The assembly of  claim 1 , wherein the cap is close-ended and configured to act as a fluid-stopper. 
     
     
         11 . A fluid delivery system, comprising:
 a flexible plastic bag configured to retain a fluid;   a spout secured over a portion of the flexible plastic bag;   an adaptor configured to secure to the spout, the adaptor including an annular base connected to a cap-connection tube; and   a cap that is rotatably secured to the cap-connection tube, wherein the cap is configured to rotate about the adaptor in order to slice a fluid opening through the flexible bag.   
     
     
         12 . The fluid delivery system of  claim 11 , wherein the adaptor includes a cavity formed through the cap-connection tube, and wherein a portion of the spout is received and securely retained within the cavity. 
     
     
         13 . The fluid delivery system of  claim 11 , wherein the cap-connection tube includes a chamfered opening configured to align the cap into the adaptor, and wherein the chamfered opening also sealingly engages a portion of the cap as the cap is mated with the adaptor. 
     
     
         14 . The fluid delivery system of  claim 11 , wherein the annular base includes a plurality of tactile members. 
     
     
         15 . The fluid delivery system of  claim 11 , wherein the cap includes a piercing member having a cutting tooth followed by at least one smooth fin. 
     
     
         16 . The fluid delivery system of  claim 15 , wherein the at least one smooth fin is configured to push a cut flap of the bag out of a cutting envelope of the cutting tooth so that the cut flap remains connected to the bag. 
     
     
         17 . The fluid delivery system of  claim 11 , wherein the cap includes a nozzle. 
     
     
         18 . The fluid delivery system of  claim 11 , wherein the cap is close-ended and configured to act as a fluid-stopper. 
     
     
         19 . An assembly configured to secure to a spout of a bag in order to pierce the bag to allow fluid to flow therethrough, the assembly comprising:
 an adaptor configured to secure to the spout, the adaptor including:
 an annular base; 
 first tactile members around the annular base, the tactile members configured to allow a user to securely grasp and hold the annular base in a steady, fixed orientation; 
 a cap-connection tube extending from the annular base, the cap connection tube having a chamfered opening; 
 a cavity formed through the cap-connection tube, wherein a portion of the spout is received and securely retained within the cavity; and 
   a cap that is rotatably secured to the cap-connection tube, the cap including
 a main body; 
 a piercing member extending from the main body, the piercing member having a cutting tooth followed by at least one smooth fin, wherein the at least one smooth fin is configured to push a cut flap of the bag out of a cutting envelope of the cutting tooth so that the cut flap remains connected to the bag; and 
 second tactile members located on an outer surface of the main body, wherein the second tactile members are configured to allow the user to grasp the main body in order to rotate the cap into piercing engagement with the bag, 
   wherein the cap is configured to rotate about the adaptor in order to slice a fluid opening through the bag,   
     
     
         20 . The assembly of  claim 1 , wherein the cap includes one of a nozzle or a close-ended stopper.
