Bag fastener for flexible bags

Abstract

The disclosed fastener for pliable food bags consists of a conical-shaped base that tapers into a round, slotted top section that is open at both ends. The device contains a slotted opening that allows for a segment of flexible bag material to be secured within the slotted section. The slotted opening extends across the length of the device and contains a protruding notch to hold plastic bags in place.

What I claim is: 
     
         1 . A bag fastener for product containers, comprising:
 a. a frustoconical body;   b. a cylindrical section integral with the frustoconical body;   c. a slot in the frustoconical body that traverses to a top of the hollow cylindrical section;   d. a notch in the slot configured for holding a flexible bag neck and retaining a bag.   
     
     
         2 . The bag fastener according to  claim 1 , wherein said top of frustoconical body is joined to said bottom of the hollow cylindrical section. 
     
     
         3 . The bag fastener according to  claim 1 , wherein said frustoconical body is hollow. 
     
     
         4 . The bag fastener according to  claim 1 , wherein said concave cylindrical section is hollow. 
     
     
         5 . The bag fastener according to  claim 1 , wherein said slot extends the entire length of said bag fastener. 
     
     
         6 . The bag fastener according to  claim 1 , wherein said notch is of rectangular shape. 
     
     
         7 . A funnel shaped, one-piece bag fastener, open at both ends and comprising:
 a. a conical-shaped base section;   b. a hollow cylindrical contoured end section;   c. a slot having a predetermined profile of said bag fastener for receiving flexible bags,   d. a cutout section within said bag fastener,   e. a notch to secure said flexible bag within said bag fastener.   
     
     
         8 . The bag fastener according to  claim 7 , wherein said base section tapers at an approximately 45-degree angle. 
     
     
         9 . The bag fastener according to  claim 7 , wherein said conical-shaped base section typically has thickness from 1 mm to 5 mm. 
     
     
         10 . The bag fastener according to  claim 7 , wherein said conical-shaped base section typically has a bottom inside diameter of 20 mm to 40 mm and a top inside diameter typically 2 mm to 12 mm. 
     
     
         11 . The bag fastener according to  claim 7 , wherein said contoured end section typically has a thickness from 1 mm to 5 mm. 
     
     
         12 . The bag fastener according to  claim 7 , wherein said conical shaped base section has a typical inside height of 7 mm to 20 mm. 
     
     
         13 . The bag fastener to  claim 7 , wherein said contoured end section has an inside diameter from 4 mm to 12 mm.
