BREAK-OFF SPOUT, POUCH HAVING A BREAK-OFF SPOUT, PRODUCTION METHOD FOR POUCH HAVING A BREAK-OFF SPOUT, FOOD OR BEVERAGE IN POUCH HAVING A BREAK-OFF SPOUT, AND PRODUCTION METHOD THEREFOR

摘要

The break-off spout of the present invention includes: a spout main body (110) having a break-off section (150) formed via a weakened section (121) such that an annular section (152) having a through-hole formed therein protrudes to the tip side; and a pair of left and right cover members (160) integrally formed with the spout main body (110) via hinge sections provided below the weakened section (121). The pair of left and right cover members (160) are formed in a shape such that, when the cover members are engaged with each other, the cover members cover a portion of the spout main body (110) above the hinge sections including the break-off section (150). An insertion port (164) through which deformation means that deforms the annular section (152) and blocks the through-hole can be inserted is provided in the cover members (160).

主权项

1. A break-off spout comprising:
a spout main body having
a tube having a channel that passes through its center anda break-off section that is formed at a tip of the tube via a weakened section and that is integrated with the tube, a tip of the channel being closed by the break-off section; and a cover that covers an outer periphery of the tube of the spout main body at a tip side of the tube; wherein a protruding annular section is provided at a tip side of the break-off section; a through-hole is formed in the annular section, wherein the through-hole communicates with the channel and is open at a tip side of the annular section; the cover consists of a pair of cover members that are formed in a state in which the cover members are divided into left and right parts, and each of the cover members is integrated with the spout main body via a hinge section that is provided below the weakened section; the pair of cover members are both provided with engagement parts that mutually engage and secure with each other, and the cover members are formed in a shape to cover a portion of the spout main body when cover members are folded upward and secured to each other to form a unified cover, the portion being above the hinge sections and including the break-off section; and insertion ports are provided at tip sides of the pair of cover members, wherein the insertion ports allow insertion of deformation means that deforms the annular section and blocks the through-hole.
