Flexible tubular container with tear-off structure

Abstract

A flexible tubular container includes a hollow, flexible tubular body having an outer circumferential surface in which a circumferential tear-off indentation mark line is formed to divide the flexible tubular body into a head section and a tail section. When contents of the flexible tubular body is squeezed to the last stage, the flexible tubular body can be forcibly twisted to tear the flexible tubular body along the tear-off indentation mark line for separating the head section from the tail section to allow further removal of the contents. The flexible tubular body further forms a splitting indentation mark line in the outer circumferential face of the tail section to allow the tail section to be further torn to form an expanded protection cap for covering the separated head section for protection against contamination of the contents caused by external dusts and foreign objects.

1 . A flexible tubular container, comprising a hollow, flexible tubular body having an outer circumferential surface in which a circumferential tear-off indentation mark line is formed to divide the flexible tubular body into a head section and a tail section, whereby when contents of the flexible tubular body is squeezed to a last stage, a user may hand twist the flexible tubular body to tear the flexible tubular body along the tear-off indentation mark line for separating the head section from the tail section for further removing the contents from the head section, the flexible tubular body further and selectively forming a splitting indentation mark line in the outer circumferential face of the tail section of the flexible tubular body to allow the tail section to be further torn to form an expanded protection cap for covering the separated head section for protection against contamination of the contents caused by external dusts and foreign objects. 
   
   
       2 . The flexible tubular container according to  claim 1 , wherein the circumferential tear-off indentation mark line and splitting indentation mark line are selectively comprised of a plurality of recessed marks that is of a predetermined length and is arranged to be spaced by a predetermined spacing. 
   
   
       3 . The flexible tubular container according to  claim 1 , wherein the circumferential tear-off indentation mark line and splitting indentation mark line are selectively made up of a continuous recessed mark.
