Definitions

  • the present invention relates to flexible packaging pouches and a method for making same. More particularly, the present invention relates to flexible pouches which are provided with a pop up opening and flow guiding features to ease the pouring of their content.
  • the content of said pouch will be first retained by said collapsed front and back sidewall panels and then suddenly dispensed, creating thereby important splashes which constitute a disadvantage of the use of said pouch.
  • the front and the back sidewall panels collapse once a top corner is cut open; the consumer has to insert his fingers into the pouch to separate said front and back sidewall panels of said pouch.
  • An object of the present invention is to alleviate the above problem, by ensuring a smooth dispensing of the contained commodity, after the pouch has been cut open.
  • Flexible packaging pouches having means to self-expand said pouches after opening have been described for instance in US-5 184 896.
  • the flexible pouches disclosed in said '896 patent allow said pouches to remain open.
  • said '896 patent does not disclose specific features to ease the pouring of a pouch's content.
  • the ridges of the present invention provide at the same time an opening which pops open and flow guiding features on a flexible pouch in a simple manner, by manipulations on the pouch film only. It is therefore an advantage of the present invention to provide a flexible pouch that accomplishes the aforementioned objectives at minimal cost.
  • the present invention is a flexible pouch (1) having front (2) and back (3) sidewall panels superimposed upon one another and sealed together along their peripheral edges (4) to form a closed pouch structure, said pouch having also an opening region (5) and each of said front or back sidewall panels comprise at least one ridge wherein the ridge (6) of the front sidewall panel corresponds to the ridge (7) of the back sidewall panel and wherein said ridges emerge into said opening region so as to pop open when said opening region is opened.
  • the flexible pouch comprises a corner as the opening region and said ridges run towards the apex of said corner so as to create a pour spout shape that pops open when said corner is opened.
  • FIGS 1 and 2 illustrate a flexible pouch of the present invention generally indicated as (1).
  • the pouch (1) includes a front (2) and a back (3) flexible sidewall panel which are superimposed over one another and sealed together along their peripheral edges (4) to complete a closed pouch structure. Said pouch made by two superimposed sidewall panels also has an opening region (5).
  • Said flexible pouch further comprises at least one ridge (6) located on said front sidewall panel (2) and at least one ridge (7) located on said back sidewall panel (3).
  • the ridges of each sidewall panel correspond to the ridges of the other sidewall panel.
  • said ridges cross an intended cutting line (8) of the opening region so as said ridges pop open by cutting open said line creating thereby a predetermined expanded configuration which facilitates the dispensing of the product contained in such a pouch.
  • the length, the number and the relative position (angle) of the ridges may be selected so as to predetermine the configuration desired when the pouch pops open after the opening region is opened.
  • a variety of combinations are suitable as long as the pouch pops open when it is opened. It is therefore an advantage of the present invention that the number and the relative position of the ridges are available to adjust the specific expanded configuration desired.
  • Figure 3 illustrates a flexible stand-up pouch wherein the bottom can be formed with additional panels.
  • Many stand-up pouches have been described in the art as for instance in EP-0 334 242 or US 5 184 896.
  • Preferred herein are the stand-up pouches formed from two sidewall panels and a bottomwall panel formed from a gusset, i.e. doypacks.
  • the flexible pouch according to the present invention comprises a corner as the opening region and said ridges run towards the apex of said corner so as to create a pour spout shape that pops open when said corner is opened.
  • a stand-up pouch having a corner as the opening region (5) located on the top peripheral edge and said ridges run towards the apex of said corner and terminate on the edge of said pouch or shortly before so as to create a predetermined lozenge configuration that pops open when said corner is opened.
  • said opening region or corner is provided with either a printed cutting line (8) or a line of weakness (8) or both.
  • a printed cutting line can be provided either on the front or the back sidewall panels so as to indicate to the consumer where to cut or tear.
  • a line of weakness can also be provided to facilitate easy opening without the need of an opening utensil.
  • Said line of weakness may be formed by, for example, either a line of lower thickness or perforating or scoring sidewall panels with a laser or a knife either individually before sidewall panels are sealed together, or collectively after they have been sealed together.
  • One or both ends of said line of weakness may further be terminated with a notch or a slit which aid in starting a tear along said line when the pouch is opened by the consumer.
  • the flexible pouch has a handle (9) to ease its manipulation.
  • Said handle is preferably located on the side opposite to said opening region or corner and most preferably on the top corner on the side opposite to the opening corner.
  • the present invention may be equally applied in containing different type of products such as, but not limited to, dry or powdered or liquid beverages, or other food products, automatic dishwasher detergents, laundry detergents, softeners and hard surface cleaners.
  • the flexible pouches according to the present invention are also particularly suited to be used with a product intended to refill a reusable container thereby allowing said pouches to collapse when discarded. This satisfies environmental protection considerations as such a pouch can be rolled up after use, thereby reducing the volume of generated waste material.
  • the sheet of material used herein is a composite sheet constituted by at least two layers of different materials such that one of said materials is thermally weldable while the other is not, or such that said materials are thermally weldable at different temperature ranges.
  • the preferred construction of the film is a multi-layer lamination of a plastic/paper material or a multi-layer lamination/coextrusion of any plastic material available to the man skilled in the art, i.e. polyethylene (HDPE or LDPE) or polyethylene terephthalate (PET) and polyamide (Nylon) having a thickness of 40 to 200 micrometers.
  • Preferred multi-layered film has a first and second thermoplastic material which is heat sealed upon the application of heat at temperatures within different ranges.
  • the preferred temperature for heat sealing the material on the interior surfaces of the peripheral edges of the wall panels is from 130°C to 150°C.
  • the heat temperature of the polyethylene is from 125°C to 190°C.
  • the preferred temperature for heat sealing the material on the exterior surfaces of the peripheral edges of the wall panels is from 210°C to 250°C.
  • the heat temperature of the Nylon is from 190°C to 280°C. Other materials, thicknesses and heat sealing temperature ranges are possible.
  • thermoplastic materials such as polycarbonate, polyester polyvinylidene chloride and other higher temperature sealing thermoplastics may be suited for the Nylon and polyolefins, polyvinylchloride and other lower temperature sealing thermoplastics may be substituted for the polyethylene.
  • the interior polyethylene type materials to be used herein have a thickness of from 5 to 170 micrometers whereas the exterior Nylon type materials to be used herein have a thickness of from 0.5 to 60 micrometers.
  • the present invention further encompasses processes for the manufacture of the flexible pouches described herein.
  • the process may be a continuous, a semi-continuous or a multi-step batch process.
  • the components used in the method are individually well-known in the art, see in particular the US patents to Doyen et al and Kan (US-3 380 646).
  • the process for making a flexible pouch according to the present invention comprises the steps of:
  • Said steps 1) and 2) may be carried out in the previously described process between the steps c) and d). However, it is not critical to the process of the present invention in which sequence said steps 2) and d) may be done, i. e. said step d) may be done either after said step 2) or just before said step 2).
