Definitions

  • the present invention relates to a container of flexible material, particularly for liquid, viscous or granular products.
  • Containers of the above type made of flexible single-layer or multi-layer material, with one or both outer surfaces heat sealable, for example of polyethylene, are known and obtained by successive folding and sealing, normally from a double film.
  • These containers also known as stand-up containers, normally have a widened, reinforced base and are tapered towards the top.
  • US-A-4978025 on which the preamble of claim 1 is based, discloses a closed container for flexible material, wherein an armature of semi-rigid material is provided to improve the stability of the container.
  • EP-A-0311824 discloses a paper bag having partition walls which divide the inner space of the bag in a plurality of compartments in order to better hold and protect the goods, especially bottles.
  • the aim of the invention is to eliminate the aforementioned drawbacks, providing a container of flexible material for liquid, viscous or granular products, that maintains a perfectly upright position under any condition, avoiding crosswise swelling.
  • a second aim of the invention is to provide the package with greater stability, both when it is full and during the subsequent emptying stage.
  • Another aim of the invention is to provide such a container that can be made simply and economically.
  • the container according to the invention is prepared with at least one inner reinforcement, which prevents the opposite side walls from separating beyond a certain limit when the container is filled with product.
  • This reinforcement advantageously consists of a tubular element or sleeve, which is placed inside the container and fixed by means of two respective weld lines to each of the two opposite side walls of the container.
  • each reinforcing element could consist of a diaphragm with the ends welded to the two opposite side walls of the container, diaphragm which lies folded inside the container when the container is in the flattened state, before filling, and spreads out, allowing a maximum widening of the container corresponding to its length, when the container is filled.
  • a plurality of reinforcing elements are placed, in order to avoid possible swelling in areas at a distance from that where a single reinforcing element would be situated.
  • the container according to the invention has been indicated as a whole with reference numeral 1. It is a container for liquid, viscous or granular products, also known as a stand-up container, made of flexible material in one or more layers, heat-sealable on at least one surface.
  • the container 1 has a standing base 2 and two opposite facing side walls 3, each welded to a respective half-perimeter 4 of the base 2, and welded to each other at the side edges 5 and the upper edge 6, after filling.
  • the container 1 thus takes on an upward tapering shape.
  • the two opposite facing side walls 3 are not perfectly squared, that is with their side walls at right angles to the base, but slope inwards, so that the container 1, when filled, takes on a substantially conical shape.
  • the container 1 is shown in the flattened form, that is with the base 2 folded and the two opposite side walls 3 touching each other, whilst in Figure 2 the container is shown in the condition of use, after filling.
  • the container 1 shown in figures 1 and 2 is a container for liquids, and for this purpose it is provided with a pouring nozzle 7 in the upper part of one of its side edges 5, whilst on the opposite side it is provided with a carrying handle 8, formed by making an opening in the corresponding welded strip 5, suitably wider than that in which the nozzle 7 is provided.
  • Figure 3 shows a container having a greater width than that of Figures 1 and 2, and provided with an upper handle.
  • Figure 3 the same reference numerals as in Figures 1 and 2 have been used to indicate similar or like elements.
  • the essential difference between the two types of containers illustrated is that in the one in Figure 3 two reinforcing elements 10 are used, which will now be described, instead of one as in the embodiment in Figures 1 and 2.
  • At least one reinforcing element 10 is provided, shown in isolation in Figures 4 and 5, and substantially shaped like a sleeve or tubular element, with two opposite surfaces 11, which are heat sealed by means of two respective weld lines 12, to the corresponding opposite walls 3 of the container 1, inside which said reinforcing elements 10 are housed.
  • the material forming the reinforcing elements 10 is also a flexible single-layered or multi-layered material, with at least one surface of heat-sealable material, such as polyethylene or the like, to allow welding to the corresponding walls 3 of the container 1.
  • the two weld lines 12 are advantageously arranged so as to diverge slightly towards the top, as shown in the appended figures, so as to allow the container a greater resistance to swelling.
  • the reinforcing element 10 when the container 1 is flattened, before filling, the reinforcing element 10 is also flattened, folding around two opposite fold lines 20 substantially positioned at the midline of the other two opposite surfaces 21 of the reinforcing element 10, causing the maximum separation between the two opposite side walls 3 of the container 1 during use.
  • Figure 5 shows the reinforcing element 10 in the open position, after filling of the container 1.
  • the tubular reinforcing element 10 does not cause any impediment to passage of the product, whether liquid, viscous or granular, whilst after filling, by taking on the shape shown in Figure 5, it prevents the opposite walls 3 of the container form separating from each other by a distance greater than that of the surfaces 21 of the reinforcing element 10, thus avoiding troublesome swelling or bulging of these types of containers.
  • the container 1 can be made to take on the desired shape, after filling, always avoiding problems of swelling of the container.
  • the reinforcing element can be replaced by a simple diaphragm or membrane, substantially corresponding to one of the surfaces 21 of the element illustrated in Figure 4 and 5, the opposite ends of which are welded to the opposite walls 3 of the container 1.
  • the reinforcing elements 10 according to the invention are inserted in the container during the production cycle thereof, between the two films destined to form the two opposite walls 3 of the container, and the weld lines 12 are advantageously made from the outside of the container.
  • the reinforcing elements 10 give the container greater stability thanks to the beam effect attributable to the inner connection between the two opposite walls 3.
