The layers are typically coextruded through a specialized feedblock or specialized die that will bring diverse materials into contact while forming the film. Alternating layers of elastomeric films and non-elastomeric films may be used. Films useful in the present disclosure may have anywhere from 3 to 100 layers of different film combinations, such as 3 to 10 layers.
  • the multilayer film comprises two polyolefin layers having an elastomeric film layer therebetween. Additionally the elastomeric film layer(s) and non-elastomeric film layer(s) may be the same thickness or different thicknesses.
  • the cover may be manufactured on a continuous basis and then converted into the desired shape and size of the end desired cover. This converting may be accomplished using any conventional method including die cutting, rotary die cutting, laser cutting, water jet cutting and the like.
  • the processing conditions will be optimized to achieve the desired polymer properties. These processing conditions include the chill and/or quench temperatures.
  • a porous material may be placed on top or bottom of the elastomeric layer.
  • typical porous materials include: scrims, grids, screens, foamed substrate, nonwovens, patterned substrates and the like.
  • the amount of porosity in the porous material can be optimized depending on the cover. Without being bound by theory, it is believed that the elastomeric material in the elastomeric layer can flow through the porous material to provide re-sealing of perforations. Likewise the porous material provides or acts as a spacer in the cover.
  • re-sealing can be achieved by providing porosity in the cover itself. This can be accomplished through various techniques, such as foaming techniques or injecting gas into any of various layers in the cover during processing.
  • the elastomeric layer is applied such that it has porosity or air gaps between itself and the layer above or below it. During extrusion for example, the elastomeric layer is non- uniformly applied to the upper lid creating air bubbles or air gaps.
  • expandable materials such as expandable microspheres
  • Expandable microspheres include those commercially available under the trade designation "EXPANCEL” from Eka Chemicals Inc., Duluth, Georgia.
  • An examplary cover made using expandable microspheres includes a multi-layer film construction of 2 or more layers in which one or more than one layer contains an additive/filler, which can be a blowing agent, such as expanding microspheres. This multi-layer film can be adhered to the top surface of the cover by using a pressure sensitive adhesive which is coated to one of the two outside layers of the multilayer film.
  • the multi-layer film is a multi-layer film patch, which only covers a portion of the top (area) of the presently disclosed capsule cover. In some embodiments, this multi-layer film is laminated to previously disclosed cover films, which then cover the entire top (area) of the presently disclosed capsule cover.
  • an intermediate layer between the elastomeric layer and the layer above and/or below it.
  • This intermediate layer is selected such that there is poor or low adhesion between the elastomeric layer and the intermediate layer.
  • the low adhesion between the elastomeric layer and the intermediate layer enables the elastomeric layer to separate from the intermediate layer thereby allowing the elastomeric material in the elastomeric layer to flow through the perforation(s) for re-sealing.
  • an elastomeric layer of polypropylene skins with a styrenic block copolymer core can be formulated to have low adhesion to an ethylene vinyl acetate (EVA) film, which could be useful as an intermediate layer in the present disclosure.
  • the presently disclosed cover includes a combination of a mesh layer with an elastomeric layer where the elastomeric layer includes a tackifier.
  • the mesh layer provides space to enable the tackified elastomeric material in the elastomeric layer to flow and re-seal the perforation(s).
  • the presently disclosed cover includes a combination of an elastomeric layer where the elastomeric layer is attached with an adhesive which softens at temperatures of the injected liquid.
  • an adhesive which softens at temperatures of the injected liquid.

Abstract

La présente invention se rapporte à un récipient, comprenant : (a) un couvercle comprenant au moins une couche d'élastomère ; et (b) un composant alimentaire contenu dans le récipient, le composant alimentaire étant un composant alimentaire liquide ou un composant alimentaire solide. Le composant alimentaire solide est conçu pour produire un produit alimentaire fluide quand il est mis en contact avec un liquide. Le couvercle est conçu pour être percé par au moins un dispositif de transfert de liquide en vue de l'injection ou de l'extraction du composant alimentaire liquide ou du produit alimentaire fluide. Lors du retrait du ou des dispositifs de transfert de liquide du récipient, le couvercle est conçu pour se refermer hermétiquement lui-même pour éviter les fuites du liquide, du composant alimentaire liquide, du produit alimentaire fluide ou de combinaisons de ceux-ci. L'invention se rapporte également à un récipient comprenant un piston-plongeur et un ressort. L'invention concerne aussi des procédés d'utilisation des récipients précités.
