Definitions

  • the present invention relates to a sealed plastic film pouch containing a liquid and a free-floating straw therein and wherein air is evacuated from a space within the pouch to facilitate the manipulation of the pouch by collapsing its side walls to grasp the straw and puncture the pouch, and further wherein the bag is formed from a multilayer film having an inner sealant layer exhibiting a self-sealing behavior about the straw in the punctured area to provide a seal about the straw.
  • GB-A-789 368 teaches a plastic film pouch for containing a liquid product.
  • the film pouch has opposed side walls sealed about a peripheral edge thereof to define a sealed inner chamber. At least a portion of at least one of the side walls is formed of transparent film for visual access to the inner chamber.
  • a straw is located freely within the inner chamber.
  • a liquid is contained within the inner chamber and occupies a certain volume of the inner chamber, wherein the straw can be grasped in said liquid and can be manipulated to puncture the plastic film pouch whereby to extend a portion of the straw exteriorly of said pouch to extract liquid from said pouch.
  • the patent does not teach the expulsion air to facilitate grasping the straw.
  • Another feature of the present invention is to provide a sealed plastic film pouch having a liquid and a free-floating straw therein and wherein a predetermined quantity of air has been evacuated from a space contained within the inner chamber of the pouch.
  • Another feature of the present invention is to provide a sealed plastic film pouch containing a liquid and a free-floating straw therein and wherein the plastic film is a multilayer film having an inner sealant layer possessing a substantially self-sealing behavior about the straw in a punctured area of the bag when in use whereby to provide a seal about the straw.
  • Another feature of the present invention is to provide a method of forming a plastic film pouch with a liquid and straw disposed in the pouch and which substantially overcome the above disadvantages of the prior art and which meets the required needs.
  • the present invention provides a plastic film pouch for containing a liquid product.
  • the film pouch has opposed side walls sealed about a peripheral edge thereof to define a sealed inner chamber. At least a portion of at least one of the side walls is formed of transparent film for visual access to the inner chamber.
  • a straw of predetermined rigidity is located within the inner chamber. The straw has a length shorter than the side wall.
  • a liquid is provided within the inner chamber. The straw is free floating in the liquid and displaceable in the liquid across the side walls of the chamber.
  • the liquid contained within the inner chamber occupies from about 60% to about 90% of the volume of the inner chamber.
  • the pouch is characterized in that the remaining volume of the inner chamber has a portion of air evacuated therefrom in sufficient quantity to permit the liquid co be displaced within the inner chamber when the side walls are collapsed towards one another to grasp the free floating straw in the liquid and manipulate it to puncture the plastic film pouch whereby to extend a portion of the straw exteriorly of the pouch to extract liquid from the pouch.
  • the sealed plastic film pouch of the present invention A liquid product 11, as well as a free floating straw 12, are contained within an inner chamber 13 of the pouch 10.
  • the plastic film pouch has opposed side walls 14 and 15 which are sealed about a peripheral edge 16 thereof.
  • the pouch 10 is formed of transparent film material whereby to provide visual access to the free-floating straw 12 and the liquid product. Of course, the film material may be printed while still providing visual access to the inner chamber thereof.
  • the front side wall 14 is provided with a printed target area 17 to indicate to the user where it is preferable to puncture the bag, although the straw can be oriented to puncture other areas, but the corners are preferred.
  • the liquid product 11 contained within the bag occupies from about 60% to about 90% of the volume of the inner chamber 13.
  • the remaining volume of the inner chamber has a portion of air evacuated therefrom in sufficient quantity to permit the liquid to be displaced by collapsing the side walls against one another to facilitate grasping of the straw.
  • the liquid product contains approximately 84% of the volume of the inner chamber.
  • these pouches are preferably, although not exclusively, dimensioned to contain liquid products in volumes from 3 ounces to 24 ounces.
  • the plastic film pouch 10 is of rectangular shape and is provided with a bottom seal 18, opposed side seals 19 and 19' and a top seal 20 about the opposed side walls 14 and 15 whereby to form a rectangular transparent film pouch.
  • the film pouch need not be entirely transparent and as shown in Figure 2B, the rear side wall 15 is formed with a pigment to provide a solid colored wall which is not transparent.
  • the front wall 14 may have opaque colors printed on portions 14' thereof while maintaining a large transverse transparent section 14' for visual access of the straw 12 located within the pouch. Of course, printed matter may also be applied across the transparent section 14", provided one can still see through the transparent section to locate the straw.
  • a multilayer resin film material having an inner sealant layer 26 is utilized.
  • Such a multilayered film material is illustrated in Figure 6 and it consists of a laminated or extrusion-coated plastic film comprising an inner sealant layer 26 which is selected from a linear low or very low density ethylene-octene copolymer or a metallocene linear low density polyethylene.
  • the sealant layer has a density of 0.900 g/cm 3 and above.
  • the co-extruded resin film also has at least a different outer polymer 27 or an additive which is preferably a multilayer resin film blend of high pressure polyethylene or other linear low density ethylene-octene copolymer. It may also have a pigmented resin core 28 if it is desirable to form the pouch with an opaque back wall 15 as previously described.
  • the core could be a barrier material, such as Nylon, PET, PVDC, PP EVOH, for example.
  • Such a multilayer resin film provides for the fabrication of a pouch having excellent impact and flexural properties to prevent leaking and exhibits low heat seal initiation temperatures to permit high speed sealing of the pouch. It is preferable with these pouches that they be strong and defect-free, that is to say that there are no pin holes or folds which could lead to leaking pouches.
  • the multilayer film as shown in Figure 6 combines different resins or additives in one or more layers in order to achieve specific performance properties of the pouch 10.
  • the important aspect of this multilayer film is the inner sealant layer 26.
  • Metallocene low density ethylene-octene copolymer is preferred as it does not impart off-taste, that is to say it does not impart an acidic taste to the liquid product when contained within the bag over a long period of time. It also improves the shelf life of the liquid product within the pouch.
  • Another polymer material such as EVOH or PET could be used to provide barrier characteristics to the pouch.
  • lower cost LLDPE butene or LDPE could be used in the core to reduce costs.
  • the inner sealant layer 26 exhibits a substantially self-sealing behavior about the straw, it forms a sealing membrane 29 all about the straw side wall 12" to prevent liquid from seeping through the punctured hole 25.
  • the liquid product from the straw can be extracted by squeezing the bag to expulse the liquid through the straw 12 or else the liquid may be sipped out of the pouch through the free end 12' of the straw.
