  • a material layer overlying the adhesive layer and the fluid layer. At least one rail member positioned along the material layer.
  • a perimeter of the base layer may be defined by a first edge and an opposite second edge and a third edge and an opposite fourth edge wherein the third edge and fourth edge extend between the first edge and the second edge.
  • the adhesive layer may include a first portion and a second portion, the first portion spaced from the second portion along opposite sides of the aperture.

  • FIGURE 2 shows a cross sectional view of the bi-layer pre-oiled valve assembly
  • FIGURE 3 shows a top view of a plurality of bi-layer pre-oiled valve assemblies of the present invention
  • FIGURES 1-5 illustrates an embodiment of a bi-layer valve assembly 100 having a discontinuous fluid layer.
  • FIGURE 1 illustrates a cross sectional view along a portion of the assembly 100 of the present invention.
  • a base layer 110 of the bi-layer valve assembly 100 may include a top surface 112 and an opposite bottom surface 114.
  • the bottom surface 114 may be configured to attach to a container or receptacle 120 ( Figure 5).
  • an adhesive layer (not shown) may be used to adhere the bottom surface 114 to the receptacle 120.
  • the adhesive layer may be a permanent pressure sensitive adhesive, which is generally recognized as safe (“GRAS”) for indirect food packaging.
  • GRAS permanent pressure sensitive adhesive
  • the adhesive layer 150 may include a particular pattern that includes a first portion 152 and a second portion 154 wherein the first portion 152 is spaced from the second portion 154 to at least partially define a channel 190 therebetween.
  • the first portion 152 may be applied along the first edge 134 and the second portion may be applied along the opposite second edge 134.
  • the adhesive layer 150 may be a form of an epoxy or acrylic or rubber based adhesive which is a versatile adhesive that can be used to join a variety of materials. Additionally, polyvinyl acrylate and toughened acrylics may also serve as suitable adhesives for selected embodiments. It is also contemplated that the adhesive layers may be a type of permanent adhesive in order to facilitate permanent adhesion of respective components and/or elements.
  • the adhesive layer 150 may include a thickness between about 0.1 mil to about 3 mil, between about 1 mil to about 2 mil, and more particularly is about 1.5 mil.
  • a material layer 140 may be provided over the adhesive layer 150 and the discontinuous fluid layer 170.
  • the bi-layer pre-oil valve assembly 100 may form an outgassing path through the aperture 130 and oil layer 170.
  • the base layer 1 10 and material layer 140 may be aligned to allow for the expulsion of air/gas/fluid from the interior of the receptacle 120 when the bi-layer pre-oil valve assembly is attached to a receptacle 120.
  • the material layer 140 may generally align with the perimeter of the base layer 110. However, the present invention contemplates that the multiple layers may be splayed slightly out of alignment from one another or may be positioned so to accommodate packaging requirements or designs.
  • the material layer 140 may be made from any suitable material as desired.
  • the material layer 140 may be made from a polyester material or other polymer as this disclosure is not limited to such material.
  • the material layer 140 includes a thickness between about 0.1 mil to about 3 mil, between about 1 mil to about 2 mil, and more particularly is about 1.5 mil.
  • the channel 190 may be open or unblocked such that gases and/or other fluids may be permitted to escape the otherwise sealed package by flowing essentially one way out through the channel 190 formed in the valve 100. Conversely, when the valve 100 is closed, the channel 190 is essentially closed and/or substantially blocked such that the flow through the channel 190 formed in the valve 100 is substantially inhibited. As pressure builds within the receptacle 120, gas/fluid 200 may be expelled by traveling through the channel 190. The gas 200 may travel through the aperture 130 and cause a slight bias within the fluid layer 170 such that the gas/fluid 200 may be expelled through the channel 190 along either the third edge 136 or the fourth edge 138.
  • the fluid layer 170 may dynamically change the opening pressure of the valve 100.
  • the third and fourth edges 136, 138 may correspond to a slight opening as the pressure in the fluid layer 170 facilitate the expulsion of gas/fluid 200 from the interior of the receptacle 120 through the channel 190 out the side of the bi-layer pre-oil valve assembly 100.
  • the geometric configuration, material elasticity, and fluid viscosity may aid in facilitating the formation of the channel 190 and providing a one way path for the fluid or gas egress.
  • the fluid layer 170 further aids in providing a secure seal once the gasses are expelled from the package as the viscosity and liquid adhesion between the fluid layer, base layer and material layer prevent exterior gas from entering the receptacle 120.
  • the material layer 140 may reseat itself back onto the top surface 1 12 of the base layer 110 along the non-adhesive portion 160 creating a reusable bi-layer pre-oil valve assembly 100.
  • the atmospheric pressure that surrounds the valve assembly 100 may be greater than the interior pressure within the receptacle 120 wherein the material layer 140 may be in the closed position substantially against the fluid layer 170 at least partially along the non-adhesive portion 160.
  • the present invention further contemplates that the base layer 1 10 may have more than one aperture 130 corresponding to and aligning with a plurality of openings in the receptacle 120 to facilitate the expulsion of gas from the interior of a receptacle to the surrounding environment.
  • the aperture 130 or apertures may be circular in shape but different geometrical shapes are contemplated by the present invention.
  • the respective layers may be made from recycled or compostable film materials.
  • the present invention contemplates that the base layer 110, the material layer 140, and/or rails 180, do not need to be constructed out of the same type of material and may be dissimilar materials. In one embodiment, the base layer 1 10 and the material layer 140 may be constructed out of clear PET. The present invention further contemplates that pigments may be added to the base layer 110 and material layer 140 in order to provide a colored multi-layer construction. Additionally, any other material such as a suitably flexible films or sheets of material such as a polymer film or foil laminate are contemplated by this disclosure.
  • the discontinuous fluid layer 170 may be a low viscosity fluid such as an oil. More specifically the oil may be a silicone, mineral or vegetable oil. Additionally, the fluid layer may also be another substance with a viscosity similar to that of oil or lower than oil but yet one that is still flowable.
  • the fluid layer 170 of the present invention provides a sealant to promote selective adhesion of the base layer 1 10 to the material layer 140 at least partially along the non-adhesive portion 160. The fluid layer 170 may prevent the entrance of unwanted components from the surrounding environment into the interior of a receptacle 120.
  • valve assembly 100 may be designed to respond and release gasses into the outside environment at variable amounts of pressure that are less than or significantly greater than about 689 Pa to about 103421 Pa wherein the variable amounts of pressure are dependent upon product design or requirements.

Abstract

La présente invention se rapporte à un ensemble bicouche de soupape préhuilée, et à un procédé de fabrication, qui peut être fixé à un récipient qui offre un joint étanche résistant aux fluides mais permet l'expulsion d'une pression d'air depuis l'intérieur d'un récipient. L'ensemble de soupape peut comprendre une couche de base, une couche adhésive, une couche fluidique et une couche de matériau. La couche fluidique peut être un fluide à faible viscosité qui est appliqué au cours de la fabrication de la soupape et incorporé dans la couche de la soupape. La couche de base peut comprendre une ouverture. La couche adhésive peut être disposée autour d'une partie du périmètre de la couche de base afin de définir une partie non adhésive. La couche fluidique est appliquée le long d'une partie de la partie non adhésive de la couche de base afin de définir un canal ou un trajet pour faciliter l'évacuation d'un gaz ou d'un fluide hors du récipient.
