Definitions

  • ABSTRACT A package for liquids or food products, of the kind comprising a tubular sheath of plastic or the lilke material, each end of which is closed by a transverse weld, so as to form a bag adapted to be opened by cutting of? one of the corners thereof, characterized in that at least one of said corners is in serted inside said bag to form a tightly closed concave cavity, while it is possible to open the package by any known means.
  • the present invention relates to packages of the kind comprising a tubular sheath of plastic or the like material, each end of which is closed by a transverse weld, so as to form a bag adapted to be opened by cutting off one of the comers thereof.
  • the specific object of the present invention is to provide safe and inexpensive means, adapted to be used in automatic mass production, which ensure an efficient protection against contamination for the portions of a plastic material package which are adjacent to the opening area thereof.
  • At least one of the angles of the package or bag that is, one of the comers thereof, is inserted inside the bag, so as to form a concave cavity which is tightly closed, but enables nevertheless the bag to be opened by any known means.
  • the outer surface of said corner is protected against any contamination, from the time a product is put into the bag up to the time said product is to be consumed.
  • the corner which must be cut ofi' to enable the product to flow out of the bag is withdrawn from the interior of the package only at the very moment it is going to be cut off.
  • the corner inserted inside the package is positioned against the inner longitudinal wall of the latter.
  • the corner inserted inside the package is positioned against the inner portion of the corresponding transverse weld of the latter.
  • the tight closure of the concave cavity formed in the package can be obtained by any means, but preferably by an adhesive strip applied lengthwise over the free edges of said cavity.
  • the latter is obtained by at least one line of glue interposed between the free edges of the concave cavity.
  • FIG. I is a perspective view of a corner of a package formed according to the invention.
  • FIGS. 3 and 4 are sectional views, on an enlarged scale, illustrating two embodiments of said package.
  • the invention relates, as previously stated, to packages comprising a tubular sheath 2 said lips constituting the free edges of the cavity 6.
  • comer 5a is pushed back against the transverse wall 8 including the transverse weld 8.
  • said comer 5a is pushed back against the longitudinal wall '7.
  • connection is obtained by means of an adhesive strip 10 overlapping said two edges 9 over the whole length thereof, as shown in FIG. 3.
  • the free edges 9 of the cavity 6 are bonded together by a line of glue 12.
  • the inner cavity 6 is thus protected against any contamination, both during the storage and the transportation and handling of the package.
  • a package for liquids or food products of the kind com prising a tubular sheath of plastic or the like material, each end of which is closed by a transverse weld, so as to form a bag adapted to be opened by cutting off one of the corners thereof, characterized in that at least. one of said corners is pushed back inside said bag to form a tightly closed concave cavity, while it is possible to open the package by any known means.
  • a package as claimed in claim 1 further characterized in that that corner inserted inside the package is positioned against the inner longitudinal wall of the latter.
  • a package as claimed in claim ll further characterized in that the tight closure of the concave cavity formed in the package is obtained by at least one line of glue interposed between the free edges of said cavity.
