Definitions

  • the technical field relates generally to liners for flexible containers, and more particularly, to flexible, semi-rigid liners for soft-sided container bags.
  • Soft container bags are used for a number of applications. For example, soft cooler bags, or cut-and-sew bags, are typically used to store items that need to remain cool. Generally, a soft cooler bag is lined with heat-sealed vinyl sheeting, such as polyethylene vinyl acetate (PEVA) or polyvinyl chloride (PVC) sheeting. The soft cooler bag may then be layered with foam insulation to create an insulated bag.
  • PEVA polyethylene vinyl acetate
  • PVC polyvinyl chloride
  • a number of problems have been identified in the use of vinyl sheeting in coolers. The vinyl sheeting is typically very thin and punctures relatively easily, thereby creating leaks in the bag, which reduces the insulating properties of the cooler. In addition, the seams of fabricated liners tend to leak.
  • a hard plastic liner such as a rigid polypropylene bucket
  • the use of the hard plastic liner eliminates the benefits of collapsibility and flexibility of the soft cooler bag.
  • Some other examples of soft container bags include duffel or gym bags, and beach bags.
  • Duffel bags and beach bags are typically constructed from flexible materials, such as nylon and/or polyester, that have a tendency to absorb moisture.
  • users store damp or wet clothing or shoes in the bags, for example, after working out or going swimming.
  • the material of the bag absorbs moisture from these items and creates an unpleasant odor within the bag.
  • the moisture build-up can even lead to the formation of mildew in the bag.
  • manufacturers have typically used heat sealed seams or sewn seams in fabricated non-woven plastic liners. However, the seams in these liners eventually leak, thus causing moisture to contaminate the fabric of the bag.
  • a soft container bag is a tote bag or a carry bag, such as a grocery tote.
  • Tote bags are typically constructed from a flexible cloth material, such as canvas, nylon or other easy-care synthetics, recycled matter, or minimally-processed natural fibers.
  • condensation forms and makes the interior of the tote bag wet.
  • moisture exposure compromises the fabric of the tote bag, and causes the tote bag to stretch or tear.
  • the fabric of the tote bag absorbs the condensation and causes the exterior of the bag to become undesirably wet.
  • condensation from the cold item may cause other dry items in the tote bag to also become wet.
  • the present invention provides soft container bags having a flexible liner that can generally insulate items stored therein, while providing strength and flexibility, as well as improved leak resistance over conventional soft container bags.
  • a soft material is one that is pliable, bendable, or gives way easily under pressure.
  • An example of a flexible material is one that is capable of being bent or flexed repeatedly without significant damage.
  • a container system can include a flexible housing or bag having a cavity, and a flexible, semi-rigid liner positioned within the cavity.
  • An example of a semi-rigid material is one that is partly or moderately rigid, and can maintain its shape.
  • the liner can be the same size and shape as the cavity, or be sized to fit in a portion of the cavity.
  • the liner can include one or more openings for storage or insulation purposes.
  • the liner has shape memory, such that it can deform when a force is applied thereon, and resume its original shape without being damaged when the deforming force is removed.
  • the liner can be manufactured from a viscoelastic polymer, such as a thermoplastic or a thermoset material.
  • the liner can be secured to the flexible housing by stitches, snaps, clips, and the like, or remain removable from the flexible housing.
  • a container bag can include a flexible housing having a flexible liner.
  • the flexible housing has a base having a first perimeter, a cover having a second perimeter, and one or more sidewalls extending between the first perimeter and the second perimeter.
  • the first perimeter can be the same size as the second perimeter.
  • the cover can be secured to the one or more sidewalls using a zipper, clip, or other fastening device.
  • the base, one or more sidewalls, and cover define an interior cavity in which the liner can be housed.
  • the liner has one or more openings, and readily deforms from its original shape to a deformed shape when a force is applied to the liner without damage to the liner. When the force is removed from the liner, the liner returns to the original shape.
  • a container bag can include a flexible housing having a flexible, semi-rigid liner.
  • the flexible housing has a base having a first perimeter, a cover having a second perimeter, and one or more sidewalls extending between the first perimeter and the second perimeter.

  • the liner has a base and one or more sidewalls extending from a perimeter of the base to define an opening for housing a item.

Abstract

L'invention porte sur un revêtement souple ayant une base plane et de multiples côtés s'étendant vers le haut à partir de la base plane. La base et les côtés du revêtement souple définissent une cavité destinée à recevoir des produits alimentaires ou d'autres articles. Le revêtement souple est généralement dimensionné de façon à s'emboîter dans une cavité d'un sac conteneur souple, tel qu'une glacière à flancs souples, un sac de sport, un sac de gymnastique ou un sac à provisions fourre-tout réutilisable. Le revêtement souple apporte une rigidité et une durabilité accrues au sac conteneur souple. Alors qu'une force manuelle déforme le revêtement souple de sa forme d'origine, le revêtement est élastique et possède une mémoire de forme, de telle sorte que lorsque la force sera éliminée, le revêtement reprendra sa forme d'origine. Le revêtement est constitué d'un matériau polymère viscoélastique. En outre, le revêtement peut être fixé au sac conteneur souple ou configuré pour être amovible vis-à-vis de celui-ci.
