Definitions

  • pouch (sachet) style packages made of various very thin films, for example films of about 3 mils (0.003′′) and less in thickness, in a variety of combinations such as coextruded muti-layer plastics, metal foil/thermoformable plastics, etc.
  • one or more bulges can be formed in at least one of the walls of the pouch (sachet) style containment package to increase the volumetric capacity of the pouch and/or to reduce the amount of material used to contain a specific volume, which reduces the cost significantly without much loss of barrier qualities.
  • bulges may be thermoformed for totally plastic walls, or, in the case of metal foil/plastic laminated combinations, where the foil is very thin, for example on the order of 0.0003′′, air pressure forming has been the most efficient means.
  • the pre-heating for thermoforming is detrimental for foil/plastic combinations since it weakens the bond between the foil and the plastic film which the foil needs for support, and the foil ruptures in numerous stress cracks when being pressure formed. It has been further observed that the rounded ball comers of such bulges tend to thin out to where they also show stress cracks.
  • the invention is directed to a system which will relieve excessive thinning and stress cracking of such rounded ball corners.
  • the invention includes the formation of on or more stress-relieving formations in the bulge formation.
  • the stress-relieving formation is an indent in the wall of the bulge formation.
  • the stress-relieving formation is a bulge or protrusion extending from the bulge formation.
  • the stress-relieving formation may be a relatively shallow flat indented or protruded formation with semi-circular ends in the wall of the bulge formation.
  • FIG. 1 shows a pouch (sachet) with a bulge formation with a stress-relieving indent with semi-circular ends.
  • FIG. 2 shows another embodiment of a stress-relieving indent in the form of a channel with a semi-circular cross-section.
  • FIG. 3 shows another embodiment, with a plurality of stress-relieving indents.
  • FIG. 4 shows various shapes for stress-relieving indents or protrusions.
  • a typical pouch-style package pouch is normally rectangular.
  • a bulge member 10 may be formed in one or more walls of the pouch. These bulges with or without indents may be utilized in ordinary rectangular pouches as currently available or with various patented easy opening pouches with a flap, or with a directional tear system.
  • the bulge member 10 may be parallel to the edge seals 20 with ball corners 12 .
  • an indent 30 with semi circular ends is formed in the wall of the pouch. The tiny wall of the indent relieves the stresses of forming the ball corners 12 by flattening out a little when the ball corners 12 are formed.
  • This indent system may further be utilized to reduce stresses and thinning in various other packaging and/or other uses which require formed thin wall systems.
  • the stress relieving indents may be of a variety of shapes. It may further be recognized that multiple indents of various or similar shapes may be applied to a single unit. The concept is that the indent yields additional material when the film/foil is being formed into a greater shape by flattening or deforming as the film is stretched, thereby yielding stress relief to the greater shape.
  • FIG. 2 shows another embodiment of a stress-relieving indent in the form of a channel with a semi-circular cross-section, as indicated by the line A-A′.
  • FIG. 3 shows another embodiment, with a plurality of stress-relieving indents, having a cross-section as indicated by the line B-B′.
  • FIG. 4 shows various shapes for stress-relieving indents or protrusions.
  • the indent at C-C′ is a semi-circular indent.
  • the indent at C′′-C′′′ is a reverse indent or protrusion having a similar shape as the indent at C-C′.
  • the indent at D-D′ has a shape like a quarter-circle.
  • the indent at E-E′ has an oblong shape.
  • the indents at F-F′ and G-G′ are oblong in shape and crossed.
  • stress-relieving indent or protrusion may take a variety of shapes within the scope of the claims.
