Definitions

  • the present invention is concerned with a double bag or sack, that is, one with two compartments, each of which is provided with a separate closure, destined to contain powdered or liquid food products.
  • culinary preparations are presented in the dry, powdered state, so that they can be prepared rapidly by heating or cooking in an appropriate liquid, such as water.
  • the preparation includes two different products, destined to be prepared in two successive stages, contained in two compartments of a double bag, but which has only one opening that operates on the two compartments simultaneously.
  • a particular result of this is that the entire product must be consumed immediately without the possibility of storing one of the constituents separately.
  • GB-A-494,010 relates to a wage bag or envelope comprising two compartments intended to hold banknotes and coins separately.
  • the mouth of this bag is sealed by a simple gummed flap or flaps or other adhesive.
  • the bag is subsequently opened by removal of the same flap or flaps, thereby releasing the contents of both compartments simultaneously. There is no suggestion that the two compartments could be opened separately.
  • GB-A-2,030,109 discloses a sachet intended to contain food products and comprising two separate compartments, but again these cannot be opened independently. With this type of double bag, it is not possible to use two doses of the same product or of the same variety at different times, while maintaining the second dose under the storage conditions that existed before the opening of the first compartment.
  • the purpose of the present invention is to remedy the above disadvantages by furnishing a double bag, each compartment of which has an individual closing device, characterized by a compact form, and easy and economical manufacture and filling.
  • a double bag for powdered or liquid food products constituted by an exterior sheet folded onto itself thereby forming two external walls which meet at a common fold line and by an interior sheet between said external walls, the sheets being sealed together at their edges thus forming two distinct compartments (GB-A-2 030 109) characterized in that the interior sheet is sealed to one or both of the external walls along two lines parallel to each other and to the common fold line.
  • the external walls have two supplementary folds symmetrical with respect to the fold line, the respective zones between the sealing line and the limit of each supplementary fold constituting the opening elements.
  • a first zone forming the opening element of a compartment is arranged between the two sealing lines and a second zone, forming the opening of the other compartment, is arranged beyond the sealing line that is the farthest removed from the fold line.
  • a double bag consists of two compartments 1 and 2, delimited by the respective external walls 3 and 4 and by an interior sheet 5a, 5b which is common to the two compartments.
  • the external walls 3 and 4 are in fact constituted by a single sheet folded along a common fold line A-A.
  • the folding forms two lips inside of which the double interior sheet 5a, 5b is sealed along two sealing lines 6 and 7, which are parallel to fold line A-A and are arranged on either side of this fold line.
  • the bag also has two other supplementary folds 8 and 9, into which extend corresponding folds 10 of interior sheet 5a, 5b.
  • the bag of general reference 11 has, for example, a rectangular form, the edges B of the sheets which constitute it being glued or soldered together in a manner which is known in the art.
  • Zones D1 and D2 which are respectively between sealing lines 6 and 7, and supplementary folds 8, 9, constitute the individual opening elements of compartments 1 and 2, parallel to fold line A-A.
  • zones D1 and D2 may equip zones D1 and D2 with precut matching notches 12.
  • a bag according to the invention has two compartments, 1 and 2, as before, defined by two external walls 3 and 4 of a single sheet folded along common fold line A-A, and by an interior sheet 5.
  • the interior sheet 5 is inserted inside the lips formed by the fold line A-A and it is sealed along two parallel sealing lines 13 and 14, arranged on the same side with respect to fold line A-A.
  • a first zone D3, forming the opening element of compartment 1 is comprised between the two sealing lines 13 and 14, while the second zone, D4, forming the opening elements of compartment 2, is arranged beyond the sealing line 14 which is the farthest removed from fold line A-A.
  • Sheet 5 is also sealed on edges B.
  • a double bag In order to manufacture a double bag according to the invention, one may place the single sheet forming the external walls onto a flat surface, followed by defining a fold line and carrying out the sealing of the sheet that forms the internal walls along the two lines. This is followed by folding as well as applying the supplementary folds according to the first mode of embodiment then sealing edges B which are perpendicular to the fold line. Under these conditions, the bottom of the bag is constituted by the opening elements D1 ⁇ D2 or D3-D4 and one may proceed with filling the compartments. After filling, the side opposite to fold line A-A is sealed by any appropriate means, for example, by first folding the edge of the interior sheet 5 and an edge of an external wall 3 onto the other external wall 4, along the cover flap 15.
  • the walls may be made of any suitable sheet- like material, for example, from paper made impermeable, metal-like paper, or metal or plastic materials. In the latter case, the sealing may be carried out by thermal welding.
  • the present invention permits preservation of the product, contained in the compartment that remains closed, under the initial storage conditions up to the time when it will be used.
  • the invention permits guaranteed safe consumption with all the predictions inscribed on the packaging (composition, mode of use, storage conditions, labelling and marking), which maintains its integrity until the use of the product that it contains.
