Transit sealing plug

Abstract

The current invention discloses a transit seal plug, the seal plug to be releasably secured to a dispensing cap. The sealing member includes first and second annular sealing faces, and further also includes a gripping member which extends away from a first side of the sealing member to engage walls of a conduit. A pull tab extends from the opposite side of the sealing member, to facilitate removal of the seal plug from a dispensing cap.

What is claimed is: 
     
         1 . A transit seal plug, the seal plug to be releasably secured to a dispensing cap;
 a sealing member having first and second annular sealing faces;   a gripping member extending away from a first side of the sealing member to engage walls of a conduit;   a pull tab extending from the opposite side of the sealing member, to facilitate removal of the seal plug from a dispensing cap.   
     
     
         2 . A transit seal plug according to  claim 1 , wherein the centre of the sealing member is frusto-conical in shape, in a conformation extending away from the gripping member, forming a dish-like structure to enable the sealing portion to conform with the underside face. 
     
     
         3 . A transit seal plug according to  claim 2 , wherein the gripping member is housed within the frusto-conical structure. 
     
     
         4 . A transit seal plug according to  claim 1 , wherein the gripping member has a plurality of arms. 
     
     
         5 . A transit seal plug according to  claim 4 , wherein the gripping member is cylindrical in shape. 
     
     
         6 . A transit seal plug according to  claim 5 , wherein the gripping member is hollow to reduce weight. 
     
     
         7 . A transit seal plug according to  claim 1 , wherein the pull tab is rectangular in shape. 
     
     
         8 . A transit seal plug according to  claim 7 , wherein the pull tab has a roughened surface. 
     
     
         9 . A transit seal plug according to  claim 8 , wherein the pull tab has a profiled surface. 
     
     
         10 . A transit seal plug according to  claim 1 , wherein the seal plug is formed of plastics material. 
     
     
         11 . A transit seal plug according to  claim 10 , wherein the plastics material is selected from polypropylene (PP), polyethylene, a low density polyethylene (LDPE), medium density polyethylene (MDPE), a polyethyleneterephthalate (PETE), a polyhydroxyalkanoate (PHA), polylactic acid (PLA). 
     
     
         12 . A transit seal plug according to  claim 10 , wherein the plastics material is a recycled grade. 
     
     
         13 . A container comprising a container body, a dispensing cap having a dispensing conduit, and secured thereto and interposed therebetween in sealing arrangement, a seal plug the seal plug comprising a sealing member having first and second annular faces; a gripping member extending away from a first side of the sealing member to engage walls of the dispensing conduit a pull tab extending from the opposite side of the sealing member, to facilitate removal of the seal plug from the dispensing cap. 
     
     
         14 . A dispensing cap/seal plug assembly, the assembly comprising a dispensing cap having a dispensing conduit, and a seal plug including a sealing member having first and second annular sealing faces; a gripping member extending away from a first side of the sealing member to engage walls of the dispensing conduit, a pull tab extending from the opposite side of the sealing member, to facilitate removal of the seal plug from the dispensing cap.
