Definitions

  • the present invention relates to a container formed from a flexible flaccid sheet-like material, being especially applicable for containing formless products or products lacking consistency, said container comprising a hermetically sealed cavity, designed to enclose the product contained in the container and which is formed from a base, at least one side wall and an upper closed portion, which may have a product dispensing outlet.
  • Containers formed from flexible materials which contain liquids or formless substances therein are widely known.
  • drink containers, cosmetic products and/or products for clinical use, granulated food, etc, etc. They are generally formed so that they comprise a base and side walls, which together form a hermetic cavity.
  • the container can stand upright when it is full of the product it contains.
  • the liquid or formless substance is dispensed by cutting the upper part of the container or using a cap, in general, also arranged on the upper part of the container.
  • the containers of this type have the advantage that they adapt to the form or content of the liquid or substance they comprise, they are easier to transport and better use is made of the space where they are displayed or stored.
  • containers formed from flexible materials have some drawbacks due to their flaccid constitution, which makes them difficult to handle.
  • One of said drawbacks is that the containers lose stability as the product is consumed, so that they only stand upright when they are full of the product contained.
  • Another of the drawbacks is that they are awkward to hold as they lose shape when they are lightly squeezed.
  • the opening operation thereof involves the involuntary spilling of the product contained due to the fact that, when the container is held or squeezed, it loses shape, the product spilling very easily out of the opening.
  • stiffening elements such as rigid-polymer wire or rods, which are adhered to the flexible material which forms the container.
  • Another way of avoiding the container from bending or twisting as its content is emptied consists of performing non-linear welding between the flexible sheets which form the container, or on the sheet if it is a container manufactured from a folded flexible sheet.
  • An embodiment of this type is disclosed in patent US 5,971,613 of Bell, but, in this case, it does not resolve the problem of being able to easily handle the container without the content spilling out due to picking it up or holding it.
  • An example of this type of container is that disclosed in patent US 5,352,043.
  • An alternative to all the containers disclosed up to the present, consists of the food bag disclosed in patent US 5,137,154.
  • This patent presents a structure of a food bag which comprises two superimposed sections designed to contain food, and elongated stiffening compartments, arranged on the edges of the bag, containing a low-pressure gas therein.
  • the cavities with food, placed on top of one another are kept in a vertical upright position to avoid the food, mainly solids like crisps, nuts and dried fruit, dry pasta, etc., from being broken into pieces due to the weight the upper cavity exerts on the lower one, or due to the handling and storage of the containers.
  • the container of flexible flaccid material object of the present invention provides solutions for the problems raised, provided with the required rigidity and easy to produce and handle.
  • the container formed from a flexible flaccid material applicable for containing formless products object of the invention is characterized in that is provided with a stiffening element which comprises at least one hermetically sealed cavity of any configuration, the stiffening element extending from at least one part of the base to at least one part of the side wall edge, and a fluid or powdered material being placed inside said cavity, at sufficient pressure to stiffen the container.
  • the stiffening element comprises at least one first hermetically sealed cavity, totally or partially arranged throughout the length of the side wall edge, and a second independent cavity, totally or partially arranged on the base of the body.
  • the container of flexible flaccid sheet-like material is also characterized in that it comprises a base and two side walls, the hermetically sealed cavities containing fluid or powdered material, throughout the length of the wall edges, and ending in at least one part of the base.
  • Fig. 1 represents a perspective view of a container according to the invention
  • Fig. 2 is a side elevation view of the container
  • Fig.3 corresponds to a diagram of the base of the flexible sheet container in accordance with the invention.
  • a container of flexible flaccid sheet-like material 1 comprises a hermetically sealed hollow body 2, whose function is for containing products which are formless or lacking consistency therein.
  • the hollow body 2 is formed from a base 3 and by at least one side wall 4.
  • the hollow body 2 is also provided with an upper closed portion 5 wherein, although not represented, it may have a product dispensing outlet.
  • the container 1 is provided with a stiffening element 6 which comprises at least one hermetically sealed cavity 7, which extends from at least one part of the base 3 to at least one part of the side wall edge 8.
  • Said hermetically sealed cavity 7 may be of any configuration and is designed to contain a fluid or a powdered material therein, at sufficient pressure to stiffen the container 1 and keep it in an upright vertical position.
  • the hermetically sealed cavity 7 of the stiffening element 6 contains, in a preferred embodiment, a fluid such as a gas, which is generally air. Liquid fluids or powdered products, such as sand or any other granulated element, can also be used.
  • the arrangement of gas or sand exerting pressure on the walls of the hermetically sealed cavity 7, permits it to be in an expanded upright position, maintaining, in turn, the container 1 in upright position.
  • a stiffening element 6 like that which comprises the container 1, arranged on at least one part of the base 3 and at least one part of the side wall edge 8, it is achieved that the container 1 is always in an upright position as the content thereof is emptied, and is not spilled by the user grasping the container 1.
  • the stiffening element 6 consists of first independent cavities 7 arranged along the edges 8 of the container side wall 4.
  • the container 1 represented also comprises second cavities T on the base 3 thereof, also independent from one another and, in turn, from the first cavities 7.
  • the array of cavities 7 and 7' facilitates that the container is always kept in a vertical upright position, and that the base 3 thereof is expanded even when there is no more formless product inside.
  • a container formed from a flexible flaccid sheet-like material 1 which comprises a base 3 and two side walls 4 joined together by longitudinal edges 8.
  • four hermetically sealed cavities 7' have been arranged which, when filled with a pressurized fluid or powder, are expanded, in turn, expanding the base 3.
  • Fig. 3 represents an example of the base 3 of the container 1 according to the invention.
  • the stiffening element 6 consists of two hermetically sealed cavities T, arranged at the ends of the base 3; and in two cavities 7, independent from the first, arranged on the edges 8.
  • the cavities 7' only extend partially along the surface and perimeter of the base 3.
  • containers 1 provided with hermetically sealed cavities 7 which extend throughout the surface and perimeter of the base 3, as a double bottom or base of the container, are also object of the invention. It is provided that, if desired, the cavities 7 arranged along the edges are connected to the adjacent cavities 7' on the container base 3, to form a single cavity and single working pressure.
  • the manufacturing process of the container 1 according to the invention consists of the general process of manufacturing containers from sheet-like material, which is folded, cut and heat-sealed to form the useful configuration to be able to contain the products of interest.
  • the volumes which will form the stiffening element 6 are created and, preferably, said volumes are filled with pressurized air and their ends immediately welded to form, in this way, the hermetically sealed cavities 7.
  • this technical solution of providing a container formed from a flexible flaccid sheet-like material 1 with a stiffening element 6 which comprises at least one hermetically sealed cavity 7 with a pressurized element therein is applicable to any form, material or size of container 1 without, due to this, due to this departing from the object of the invention.
