Definitions

  • the present invention relates to a bag for the packaging of products, preferably a mesh bag, particularly applicable to the packaging of fruit and vegetable products, such as citrus fruits or root vegetables.
  • This type of bag is usually manufactured from a flexible, continuous tubular sheet, preferably made of weldable material, generally in mesh form, which is transversely cut to form portions of tubular mesh.
  • the end mouths of these portions of tubular mesh are separately closed by means of staples or by heat-welding, which operation requires the sufficient supply of heat from the outside for the fusion of the material forming the tubular mesh, the product being contained inside the tubular mesh without the possibility of coming out of its inside as the end mouths of said tubular mesh are closed.
  • the continuous tubular mesh from which successive portions of tubular mesh are obtained is formed from a planar sheet of mesh the longitudinal edges of which are attached by heat-welding to form the actual tubular mesh.
  • bands of heat-weldable material in pairs, applied on respective faces of the tubular mesh in each end thereof, are conventionally arranged, which bands are subsequently attached by heat-welding, the end portion of the tubular mesh being partially melted and embedded between the two bands of one and the same pair.
  • the bands applied at the opposite ends of one and the same face of the tubular mesh are attached without interruption and optionally fixed by points to the corresponding face of the tubular mesh.
  • the continuous tubular mesh is formed from a planar sheet of mesh the longitudinal edges of which are attached by heat-welding, a band of heat-weldable material is applied along the line of attachment between both longitudinal edges, overlapping them to assure the correct attachment between them by the overlap of the actual planar sheet of mesh with the heat-weldable band.
  • the bags obtained have a considerable weight, therefore providing said bags with holding and transport means which allow gripping the bag as comfortably as possible is required.
  • detachable handles consists of making oblong or circular holes, suitable for allowing the passage of two or more fingers of the person carrying the bag, at the free end of the bands which, attached by heat-welding and applied in respective faces of the tubular sheet, are incorporated for the closing of the upper end of the bag, as described for example in Spanish utility model number U8801019 .
  • the holding means are arranged in one of the longitudinal ends of the bag, which makes it difficult to access it when the bag is supported at rest on a flat surface.
  • the bags have an oblong configuration, more elongated than narrow, they adopt a horizontal position, supported on a side of the tubular mesh, when they are left on a support surface such as a shelf for example.
  • Spanish utility model U1027615 discloses a mesh bag comprising a central body carrying the products to be contained and having longitudinally arranged a narrow strip of strong synthetic material, welded at its ends to the ends of the mesh bag according to the actual closing welds thereof, means for holding the bag like a longitudinal handle being determined.
  • the strip or band with a small width forms a longitudinal handle, unlike what is known by documents EP405595 , U1050533 or U8801019 which use handles in a transverse arrangement and arranged at an end of the bag, this solution still does not solve the problem of different elements for manufacturing the bag and the actual handle still being required.
  • the bag of the invention is intended for the packaging of fruit and vegetable products and is essentially characterized in that it comprises a flexible tubular wrapping housing the product in its central portion, the two end longitudinal portions of the tubular wrapping being empty, closed and attached mutually and inseparably, said attachment determining a single closing area of the bag common for both ends of the tubular wrapping, the mentioned end longitudinal portions forming a handle intended for gripping the bag and from which, when the bag is gripped, the mentioned central portion of the wrapping, and consequently the product housed therein, is suspended.
  • the bag is provided with a handle formed by the actual material forming the tubular wrapping, without needing to add external elements or detachable handles, as occurs in the bags known to date.
  • the handle is formed by a compactable portion of the material forming the tubular wrapping in its end longitudinal portions, the handle has a certain thickness and the bag can be gripped more comfortably.
  • the two end longitudinal portions of the tubular wrapping are constricted and juxtaposed.
  • the end longitudinal portions are tightened in respective points contiguous to the central portion of the tubular wrapping, determining respective ends of the handle.
  • the handle is provided with a transverse strip attaching respective points contiguous to the central portion of the tubular wrapping, an arched bag portion forming the actual handle being determined above the transverse strip.
  • one of the ends of the transverse strip is attached to the handle in the single closing area of the bag, the arched bag portion forming the handle being formed by one and the same end longitudinal portion of the tubular wrapping.
  • the rigidity of the transverse strip is sufficient to maintain the points of attachment with the handle separated when the bag is at rest and rests supported on a shelf or the like.
  • the transverse strip is arranged in relation to the wrapping such that the end edges of the transverse strip are folded over themselves, surrounding at least partially and tightening a corresponding section of the tubular wrapping.
  • the mentioned end longitudinal portions of the tubular wrapping are attached to one another by means of stitching, stapling or the like.
  • the tubular wrapping is formed from a plastic material and the two end longitudinal portions of the tubular wrapping are attached to one another by welding.
  • the tubular wrapping is formed from a plastic material and the two end longitudinal portions of the tubular wrapping are attached to one another and to the transverse strip by the fusion of the actual material forming the tubular wrapping and the transverse strip.
  • the tubular wrapping is formed by an extruded-type or woven tubular mesh.
  • Figures 1 to 3 depict respective bags 1 for the packaging of fruit and vegetable products 4 which comprise a flexible tubular wrapping 2 housing the product 4 in its central portion 3.
  • the tubular wrapping 2 is formed from a material such as cloth, plastic, leather or paper and the two end longitudinal portions 5 and 6 of the wrapping are gathered compacted and juxtaposed along a section 15, and inseparably attached along an attachment area 7, sufficient to form an elongated, tightened and narrow closing area determining a handle 7a.
  • the end longitudinal portions 5 and 6 are attached in this example by means of a series of staples 11.
  • the tubular wrapping 2 is breathable and provides the bag 1 with the optimal features for the packing of perishable products such as fruit and vegetable products 4. More specifically, the tubular wrapping 2 is formed by a woven tubular mesh, made in a woven fabric forming a meshing of wide openings with plastic filaments with sufficient strength to retain the expected weight of the product 4, or of extruded type, the tubular mesh being obtained by the extrusion and expansion of a continuous laminar element of plastic material provided at the rear part with multiple openings, which after a drawing or extension process is transformed into a mesh with an appearance similar to a mesh of woven fabric.
  • the two end longitudinal portions 5 and 6 are as in the previous case gathered, compressed and put together along a section 15 sufficient to form a handle 7a, but in the example depicted in Figure 2 the gathered end longitudinal portions 5 and 6 are attached along an attachment area 7 by welding.
  • end longitudinal portions 5 and 6 can be put together along the section forming the handle 7a either by the juxtaposition of both portions, previously constricted in a disorderly manner or folded over themselves, preferably along longitudinal fold lines, in an intertwined manner or by means of the introduction of a end longitudinal portion 5 or 6 in the other end longitudinal portion 6 or 5, both portions being compacted or constricted in a disorderly or orderly manner before or after the operation of introduction of a first portion in the second portion, simultaneously or separately.
  • the attachment by welding can be carried out by the fusion of the actual material forming the tubular wrapping 2, i.e., by the fusion of the tubular mesh along the attachment area 7 without using external element for such purpose.
  • the fusion of the material forming the wrapping would occur by means of the application of ultrasounds.
  • the bag 1 obtained incorporates a handle 7a formed by the actual material forming the tubular wrapping 2, preventing having to add detachable handles as occurs in the bags known to date, and even preventing the use of external elements to perform the closing of the longitudinal ends 5 and 6 of the tubular wrapping 2, as occurs in the bag 1 according to the example of Figure 2 .
  • the handle 7a is formed by a compact, tightened mass of the material forming the tubular wrapping 2, the handle 7a is provided with a certain thickness and the bag 1 can be gripped more comfortably by the carrier.
  • the handle 7a is provided with a strip 16, preferably bearing identifying and/or advertising legends and graphics, arranged taut between two points to opposite areas of the handle 7a, both contiguous to the central portion 3 of the tubular wrapping 2.
  • the transverse strip 16 is advantageously made integral with the tubular wrapping 2 by means of welding, being able to simultaneously carry out the mutual attachment between the two end longitudinal portions 5 and 6 along the attachment area 7, and the attachment between such portions and the transverse strip 16 when the latter is applied or surrounds the mentioned attachment area 7, as depicted in the embodiment of Figures 4 and 5 .
  • the attachment area 7 can be short, being formed for example by a mere transverse weld segment, or can be more elongated, being formed by several separated transverse weld segments or by respective juxtaposed or overlapped sections of the end longitudinal portions 5 and 6 mutually attached by thermofusion.
  • the transverse strip 16 is rigid or semi-rigid, the points of attachment of the transverse strip 16 with the handle 7a are maintained separated at a predetermined distance, such that the arched bag portion is upright, facilitating its gripping when the bag is supported on a shelf or the like. This effect would be smaller in the event that the transverse strip 16 were formed from a material which is ductile in excess, which could be easily deformed when the bag rests on a shelf or the like.
  • the length of the transverse strip 16 can vary. However, it is possible to select a length such that, once attached to the tubular wrapping 2 forming the handle 7a, when said transverse strip 16 is tensed the separation distance between the two branches 7a is comprised between approximately 50 mm and approximately 150 mm, so that the handle 7a can be comfortably gripped by a user. In the embodiment depicted in Figures 3 and 4 , it is furthermore observed that by selecting a suitable length, the transverse strip 16 can be arranged in a vertical plane when the bag 1 is gripped.
  • the end edges 14 and 15 of the transverse strip 16 are folded over themselves surrounding at least partially and tightening the tubular wrapping 2 in respective points A and B contiguous to the central portion 3 of said tubular wrapping 2.
  • the mentioned points are actually formed by sections of tubular wrapping 2. It is thus achieved that the section or sections of the tubular wrapping 2 forming the mentioned arched portion of the handle 7a is maintained without expanding transversely, adopting an ergonomic compact shape, like a rope, and which facilitate its gripping.
  • the handle 7a can be provided with different finishes by varying the length of the constricted sections.
  • the tubular wrapping 2 is likewise tightened in two points A and B contiguous to the central portion 3, but unlike the bag of Figures 3 and 4 said points are not attached by one and the same transverse strip, but rather the wrapping 2 is tightened by means of independent elements 12 and 13, the configuration of which can vary according to the length of the sections to be tightened of the tubular wrapping 2.
  • the handle 7a can be provided with a more compact shape, its transverse expansion being prevented, by varying the length and proximity of the mentioned points A and B.
  • tubular wrapping 2 forming the bags 1 described above can be obtained from originally planar sheets, attached along the longitudinal edges thereof.
  • the tubular wrapping 2 in this sense, and in the event that the tubular wrapping 2 is formed by a tubular mesh, the latter can be a seam-free extruded mesh or can be formed from a planar woven mesh, with its longitudinal edges attached by heat-welding for example.
