Definitions

  • the present invention relates to a flexible plastic bag of the type obtained from at least one strip of plastic film shaped so as to determine by soldering a bottom on which the bag rests, two side walls, a dorsal face forming stiffening and gripping zone connecting the two side walls, a front face corresponding to the side where the pouring of the contents of the bag takes place after opening it and which is provided with a means of stiffening and stabilization of the bag.
  • US-A-3462067 describes a sachet of the type described above, but which does not allow the sachet to be closed after a first use.
  • the present invention proposes to remedy these drawbacks.
  • a bag of the above type in which the means consists of a buttress of generally oblong shape and is made integral with the bag by two lines of welding or bonding one arranged substantially at the base of the front face, the other slightly offset from the upper part of said buttress, thus determining an area open on 3 sides and in particular towards the top of the bag where the pouring opening.
  • the buttress means is provided at its upper part with means for closing and pinching the upper horn of the bag through which said pouring takes place, this latter means consisting essentially of two legs substantially symmetrical with respect to the longitudinal axis of the buttress and cooperating with a finger disposed between said legs.
  • the buttress will preferably be arranged in such a way that its base (6 ′) can, when the sachet is placed on a flat surface, bear on said flat surface.
  • It may be of any material, for example synthetic material, possibly of recycling to limit the cost price, of cardboard, etc., this in a nonlimiting manner.
  • front buttress may be used, which advantageously fulfill, in addition to the desired function, namely stiffening and stabilization of the bag, one or more complementary functions.
  • the buttress cooperates in the closure of the bag, once it has been opened.
  • the buttress is generally oblong and trapezoidal. It is made integral with the bag (1) by two welding or gluing lines (13,14) arranged one (13) substantially at the base of the front face, the other (14) slightly offset from the upper part of said buttress (12), thus determining an area (15) open on 3 sides and in particular in the direction of the top of the bag where the pouring opening (16) is to be made.
  • FIG. 8 This structure of the upper part of the bag is shown, enlarged, in FIG. 8.
  • the upper horn (17) comprising the opening (16) is folded against the buttress (12) and inserted between the zone (15) and the front face of the bag, as shown in the figure 9.
  • the bag comprises a buttress (18) provided at its upper part with means (19) for closing and pinching the upper horn (17) of the sachet.
  • the means (19) consists essentially of two legs (20, 21) substantially symmetrical with respect to the longitudinal axis of the buttress (18) and cooperating with a finger (22) disposed between said legs.
  • the closure is obtained by folding the upper horn (17) of the bag so as to arrange it over the tabs (20, 21) under the finger (22), where it is held by the clamping effect thus obtained.
  • the buttress of the type described above and shown in Figures 1 to 12 may be attached to the bag by any means, such as welding or gluing, at any time during the process of manufacturing and filling the bag.
  • the buttress (6, 7, 8, 9, 12, 18) can be added by a process analogous to that making it possible to fix the stiffening and gripping element (11), as described by way of example in patent application in France No. 83-18257 in the name of the applicant.
  • the stiffening and stabilization means may consist of one or more vertical ribs (7), already shown in Figure 1.
  • these ribs (7) are used in conjunction with a buttress such as (6) of the type illustrated in the above.
  • the rib (s) (7) can also alone contribute to obtaining the desired result, namely stiffening and stabilization of the sachet.
  • FIG. 13 and 13 A there is shown a bag (1 ') provided with two vertical front ribs (23, 24) of this type.
  • the lower edge of the front face of the bag (1 ′) in contact with the surface on which it is arranged will also be reinforced by a weld (25).
  • FIGS. 14 and 14 B show an embodiment of the same type as the previous one, but with a single stiffening and stabilization rib (26), possibly reinforced by a weld (27) on the lower edge of the front face.
  • the ribs (23, 24, 26) may be produced, by way of nonlimiting example, using the following device.
  • a conformator (28) of a type known to those skilled in the art on which a film (29) is made to be shaped into a continuous rod (30), then to be filled with the liquid to be packaged and transformed into sachets or individual cushions, inter alia by means of a central cannula (31), intervention and shaping stations of the rib (s) (23, 24, 26) are provided.
  • a former (33) through which the film passes gives it a W shape.
  • a post (41) disposed downstream is provided with two spacer fingers (42, 43) which unfold the zone shaped as W so as to give it the structure sought to form the front face of the future sachet.
  • the bag (101) has on its front face (102) two edges (103, 104) which are stiffened to give the bag stability and shape.
  • These elements are added to the surface on the sheath forming the bag by gluing, sealing, welding or any other suitable process.
  • said elements will be single or composite, flat or angular etc.
  • FIG 17 a reinforcement (105) attached externally to the bag and forming an angle whose apex marks the edge of the bag.
  • the opening angle of the reinforcement (105) can be arbitrary. We can also consider giving it a certain elasticity so that the angle remains well marked even when the bag is completely filled.
  • FIG. 18 shows a similar structure with external reinforcement (106), which is applied to the edge by enveloping an insert (107) disposed parallel to said edge.
  • the insert can be made of any material.
  • the reinforcement (108) is obtained by pinching the edge of the bag, as illustrated above.
  • the angle of the external reinforcement (111) is pinched, which accentuates the marking of the edge.
  • FIG. 23 shows an external reinforcement (112) folded back on itself, determining a longitudinal cavity (113) which can be empty or inflated, thus accentuating the stiffening.
  • FIGS. 26 and 27 illustrate a device making it possible to obtain the embodiments of FIGS. 17 to 23.
  • the laying of the stiffening element will preferably be done when the film is shaped from a sheath on a shaper foreshadowing the shape and dimensions of the finished package.
  • a feeding system will convey the stiffening element which will be affixed at the level of the shaper on the film sheath.
  • the bags are obtained from a sheath (116) which passes over a matrix (117).
  • This matrix comprises, to form the front edges, one or more conformers (118).
  • the stiffening element (119) is applied by welding, gluing or sealing from a supply coil (120), by means of a suitable device (121), the nature of which is related to the method of attachment, namely welding, gluing or sealing.
  • the device (121) will for example include a head (122) of profile complementary to that of the shaper (118).
  • the system will operate in an alternative manner, that is to say that when a bag is being filled, the film advance is stopped and the device applies a stiffening element on a bag in the process of being shaped.
  • the stiffening element will be cut automatically before or during installation to the necessary length, for example the length of the edge corresponding to the filled and closed bag.
  • provision will also be made to reinforce the upper edges of the bag.
  • the structure of this horizontal reinforcement will be identical to that illustrated in FIGS. 17 to 25 for the vertical reinforcement.
  • the installation will be made from a power supply (124) and according to a procedure completely similar to that described above for the vertical reinforcement.
