Definitions

  • Bottles in general, tend to be heavier than flexible pouches and therefore the transportation and delivery cost of such bottles is more expensive, in addition, many such bottles are usually packed in cardboard boxes using cardboard dividers. The cardboard dividers add another cost to the shipping process.
  • Another disadvantage with squeeze bottles is that the outlet spout is normally covered by some type of flip or screw cap.
  • frangible seal 38 another way of forming the frangible seal 38 is to seal the inside surfaces of the first and second walls, 12 and 14 respectively, to each other.
  • the inside surfaces of the first and second walls, 12 and 14 respectively must be sealant layers.
  • sealant layers it is meant that the two layers can be sealed or joined together using heat, pressure, or heat and pressure.
  • the sealant layers will allow the frangible seal 38 to be break, rupture or peel apart when a predetermined pressure or force is applied against it.
  • One way of assuring that the frangible seal 38 will break, rupture or peel apart at a predetermined pressure or force is to include a contaminant in one or both of the sealant layers. The contaminant will allow the frangible seal 38 to break, rupture or peel apart when a predetermined pressure or force is applied to it.
  • the first and second side seals, 34 and 36 respectively are formed between the first end 20 and the second end 22, that in the region of the gusset 42, the first and second walls, 12 and 14 respectively, may be bonded to: 1) each other, 2) the gusset 42, or 3) the gusset 42 and each other.

Abstract

L'invention concerne une poche destinée à distribuer une substance et un procédé d'utilisation de la poche. La poche est formée à partir de première et seconde parois de matériau souple présentant des bords périphériques conjugués qui forment une enceinte. La poche présente une largeur, une première extrémité qui est initialement ouverte, une seconde extrémité, et des premier et second joints latéraux qui s'étendent à partir de la première extrémité jusqu'à la seconde extrémité. Un joint cassable est espacé de la seconde extrémité. Le joint cassable s'étend sur une majeure partie de la largeur. La poche présente également un soufflet formé entre la seconde extrémité et le joint cassable. Le soufflet présente une ouverture d'évacuation formée en son sein à travers laquelle une substance, qui est retenue dans l'enceinte après scellage de la première extrémité, peut être évacuée.
