Tubular Pouch with Lid Piece

Abstract

The invention relates to a tubular pouch having a tubular pouch body and a lid piece and, optionally, a base, especially a standing base or stand-up base, the lid piece being fixed on the tubular pouch by means of a cuff and either the cuff being formed integrally with the lid piece or the lid piece co-operating with the cuff, the cuff at least partially overlapping the lid piece and the cuff extending around the periphery of the lid piece and at least over an end portion of the tubular pouch at the lid-piece end thereof.

1 . A tubular pouch comprising a tubular pouch body and a lid piece wherein the lid piece is fixed on the tubular pouch body by means of a cuff. 
   
   
       2 . A tubular pouch according to  claim 1 , wherein the cuff is formed integrally with the lid piece, and extends over the periphery of the lid piece and over an end portion or peripheral edge of the tubular pouch body at the lid-piece end thereof. 
   
   
       3 . A tubular pouch according to  claim 1 , wherein the cuff, is a separate component, and extends both over the periphery of the lid piece and over the periphery of the end portion of the tubular pouch body at the lid-piece end thereof and thereby holds the lid piece on the tubular pouch body. 
   
   
       4 . A tubular pouch according to  claim 1 , wherein the cuff is sealed or adhesively bonded to the lid-piece-end portion of the tubular pouch body to the outside thereof or elsewhere. 
   
   
       5 . A tubular pouch according to  claim 1 , wherein said cuff is provided with one or more opening tabs defined by grip region(s) selected from the group consisting of at least one grip region, and two co-operating grip regions. 
   
   
       6 . A tubular pouch according to  claim 1 , wherein said lid piece is placed over the associated peripheral edge of the tubular pouch body. 
   
   
       7 . A tubular pouch according to  claim 4 , wherein a desired tearing line is formed between the sealed or adhesively bonded seam of the cuff and the lid piece. 
   
   
       8 . A tubular pouch according to  claim 1 , wherein the cuff is formed by a foil strip the end portions of which are joined, sealed or adhesively bonded so that they overlap one another, the outer end portion serving as grip tab. 
   
   
       9 . A tubular pouch according to  claim 1 , wherein the lid piece has an angled edge strip, the cuff being fixed with high sealing strength on the outside of the edge strip. 
   
   
       10 . A tubular pouch according to  claim 1 , wherein the cuff is formed by a foil strip the end portions of which are joined to one another by a fin seal to form two grip tabs. 
   
   
       11 . A tubular pouch according to  claim 1 , wherein said cuff has at least one grip tab extending in the longitudinal direction of the pouch towards the base thereof or otherwise. 
   
   
       12 . A tubular pouch according to  claim 1 , wherein part(s) selected from the group consisting of said tubular pouch body, the lid piece, a base, said tubular pouch body and said lid piece, said tubular pouch body and a base, said lid piece and a base, and said tubular pouch body, said lid piece and a base is/are of relatively rigid construction. 
   
   
       13 . A tubular pouch according to  claim 1 , wherein the tubular pouch body is produced from a square or rectangular foil blank, the overlapping edge regions being joined to one another by means of sealing selected from the group consisting of a fin-seal sealing, a lap-sealing, and a fin-seal sealing and a lap-seal sealing to form a tubular body. 
   
   
       14 . A tubular pouch according to  claim 22 , wherein said least one barrier layer, is selected from the group consisting of SiO 2 , ethyl vinyl alcohol (EVOH), an oriented polyolefin, oriented polypropylene (OPP), and a metal foil. 
   
   
       15 . A tubular pouch according to  claim 1 , wherein said lid piece is made substantially of the same materials as the tubular pouch body. 
   
   
       16 . A tubular pouch according to  claim 2 , wherein part(s) selected from the group consisting of said lid piece, said tubular pouch body, and said lid piece and said tubular pouch body have a thickness in the range selected from the group consisting of from 50 μm to 1000 μm, from 100 μm to 500 μm, and from 150 μm to 350 μm. 
   
   
       17 . A tubular pouch according to  claim 2 , wherein said lid pieced, the base and the tubular pouch body are sterilisable. 
   
   
       18 . A tubular pouch according to  claim 1 , further including a standing, stand-up or other base. 
   
   
       19 . A tubular pouch according to  claim 7 , wherein the lid piece is placed over the associated peripheral edge of the tubular pouch body so that the peripheral edge of the tubular pouch body is surrounded on the inside and the outside of the edge of the lid piece. 
   
   
       20 . A tubular pouch according to  claim 1 , wherein said tubular pouch body is produced from a square or rectangular foil blank, and the tubular pouch body is part of an extruded foil tube. 
   
   
       21 . A tubular pouch according to  claim 1 , wherein said tubular pouch body is made from aluminum or other laminate having at least one sealing layer. 
   
   
       22 . A tubular pouch according to  claim 17 , said laminate includes at least one barrier layer. 
   
   
       23 . A tubular pouch according to  claim 2 , wherein part(s) selected from the group consisting of said base, and said base and said lid piece is/are made substantially of the same materials as said tubular pouch body. 
   
   
       24 . A tubular pouch according to  claim 16 , further including a standing, stand-up or other base, wherein said base has a thickness in a range selected from the group consisting of from 50 μm to 1000 μm, from 100 μm to 500 μm, and from 150 μm to 350 μm.
