Definitions

  • the present invention relates to a bag used for the packaging and marketing of horticultural products, such as citrus fruits, potatoes, etc., although said bag is usable in any other field where similar benefits are required.
  • the object of the invention is to obtain a bag that, offering the adequate performance from the point of view of mechanical resistance, requires for its construction a smaller quantity of raw material, with the consequent and beneficial impact that this has from the point of view economic.
  • Certain types of fruit and vegetable products such as potatoes have long been commercialized in plastic bags of reticular structure, which allow both aeration and direct visualization of the product.
  • plastic bags of reticular structure which allow both aeration and direct visualization of the product.
  • it starts from a tubular mesh body that closes at both ends after the product is housed inside, and one of these handles ends can be provided that facilitate manual transport after acquisition by the consumer.
  • it starts from a continuous, laminar band, which closes on itself to configure the said tubular body, through a longitudinal welding line, after which the aforementioned process is repeated.
  • Utility Model U 9701734 which the applicant himself owns, consists of using a continuous band, structured based on a strip or intermediate longitudinal strip of continuous plastic, of considerable width, susceptible of carrying printed information, two lateral strips with respect to the aforementioned intermediate band, also of plastic, but of reticular structure, specifically based on a three-wire network, these strips being fixed to the intermediate by means of linear and longitudinal welding in correspondence with their overlapping edges, complementing the band with two other fringes or strips of continuous and narrower continuous plastic, also intended to partially overlap their free edge and be fixed together by means of a longitudinal weld, to define the tubular body, subsequently fragmentable into sectors or bags that close at their ends after receiving the dose inside of expected product.
  • the indispensable requirement for obtaining a bag such as that of Utility Model U 9701734, is that the plastic material constituting the different strips or longitudinal strips participating in the band, ie continuous strips and reticular strips, are made of compatible materials to be welded together.
  • the mesh is made of low density polyethylene and the closed sheet with medium density polyethylene.
  • the bag for fruit and vegetable products that the invention proposes definitively solves the above-mentioned problem, allowing that, from a basic structuring like the one shown in Utility Model U 9701734, polyethylene of average density can be used to obtain the closed bands that they participate in it, and bi-oriented polypropylene to obtain the mesh stripes, being one and the other strips solidly joined together.
  • the invention consists in incorporating into the continuous constitutive band of the base element for the confocation of the bags, that is to say the continuous band in which the strips or bands of medium density polyethylene and bi polypropylene bands participate.
  • the continuous band in which the strips or bands of medium density polyethylene and bi polypropylene bands participate.
  • - oriented, narrow polyethylene strips that overlap the bi-oriented polypropylene strips in correspondence with the areas in which said bi-oriented polypropylene strips in turn overlap the medium density polyethylene strips, obtaining a species sandwich based on two layers of polyethylene that weld directly to each other with interposition of the polypropylene mesh.
  • Figure 1. Shows, according to a partial perspective view, the continuous band from which it is used to obtain the bag of fruit and vegetable products that constitutes the object of the present invention.
  • Figure 3 shows a rear elevation view of the bag formed at the expense of the band of Figure 1.
  • Figure 4.- Shows a cross-sectional detail of the bag of figure 3.
  • Figure 5. Shows, finally, a representation similar to Figure 1 but corresponding to a variant embodiment of the continuous band.
  • the bag that is recommended is obtained from a continuous band (1), in the that an intermediate longitudinal strip (2) of medium density polyethylene is established, capable of supporting any type of printed infbrmac (3), overlapping the marginal areas of said strip (2) being strips (4-4 ') that as before they will be made of bi-orienta polypropylene ⁇ they are structured in the form of a mesh, strips (4-4 ') that, in turn, overlap their opposite side to the marginal zone of other strips ( ⁇ of the same polyethylene as the intermediate strip (2) and of approximately half that of the latter.
  • narrow strips (6) are also superimposed, also medium density polyethylene, strips (6) that remain concrete superimposed on the strips (4-4 ' ) of bi-orientated polypropylene mesh (so that when applying to the continuous band (1) pressure and heat in these 2 overlays, the strips (2 and 5) are solidly bonded by the narrow strips (6) through the empty spaces of the meshes (as shown particularly in figure 2, so that the components difer of the web (1) are solidly joined
  • the invention is applicable in the same way to a continuous band (1), such as that shown in Figure 5, which then has a symmetrical structure on both sides of the intermediate longitudinal strip (2) of polyeth as in the case of Figure 1, present asymmetric structuring, so that both sides of it are: two-sided strips of bi-oriented polypropylene, and only one of these lattice strips (4) another longitudinal strip (7) ) Matte size matching those of the central strip (2).
  • the band continues to close on itself transforming into a tubular body, in the c marginal, longitudinal and free zones of the strips (5-5 ') or (4' -7) overlap and are fixed by welding, with the contest of the narrow strips (6) mentioned, tubular and continuous body that, as well as It is conventional, it is fragmented into portions such as that shown in Figure 3, corresponding to respective units or bags that will conveniently close at their ends.

Abstract

L'invention concerne un sac du type qui est constitué d'une bande continue qui se ferme sur elle-même au moyen d'une ligne de soudure longitudinale, définissant un corps tubulaire qui peut être fragmenté en modules correspondant à des sacs respectifs, dans lesquels la bande continue comprend des bandes longitudinales de plastique fermé, alternant avec des bandes longitudinales de maille, qui se superposent au niveau de leurs zones marginales pour être assemblées entre elles. L'invention se caractérise en ce que les bandes de plastique fermé sont en polyéthylène et les bandes de maille en polypropylène bi-orienté, la bande continue comprenant en correspondance avec chaque ligne de superposition entre les bandes citées, une bande étroite également de polyéthylène, adaptée à la maille de polypropylène, qui se soude aux bandes longitudinales citées et à celles plus larges de polyéthylène par l'intermédiaire des orifices de la maille, fixant alors cette dernière. Ainsi, la construction du sac ne nécessite qu'une petite quantité de matière première.
