PACKAGING BAG

  The present invention relates to a bag made of a weldable material, intended for automatic packaging, preferably hygiene articles, such as sanitary napkins, this bag having substantially a parallelepiped shape when it

has been completed.

  Packs of this type are generally placed on

  store shelves, so that one of the smallest

  the packaging is visible directly on the outside and that one of the side surfaces is visible from above.

  manufacturer wishes the information concerning his goods to be

  that are inscribed on these surfaces are visible on store shelves and, as such, it is important that these surfaces be whole and uninterrupted and that the

  text can be placed so that it can be read when

age is on the shelf.

  To pack the items in the bag, they are introduced

  by one of the ends of the latter, which is then closed

  When it comes to packing a number of hygiene items, such as sanitary napkins, it is important that the bag be closed

  after a towel has been removed, to prevent the

  Remaining stains may become dirty Normal means of closure

  maliciously used are what is called a "hinged lid"

  which is formed by a short side connected to one of the surfaces la-

  of the package and which comprises ap: elongation for overflowing on a portion of the other side surface and which is welded along its side edges to both side sureces of the package This hinged lid can be pulled up

  to open the small end of the packaging and can be

  closed Up by now, it has been impossible to

  to make bags with an articulated lid placed at the

  end by which articles are introduced automatically.

  the bag is closed by a weld seam after filling, so that the hinged lid is

at the opposite end.

  However, it is not practical that commercial information

  they are printed on the end

  filling of the package, since this end is called

  to be welded and cut after filling and that the posi-

  probing cords can not be determined accurately.

  especially when the contents of the Gst bag consist of compressible products such as sanitary napkins. As a result, information relating to

  goods must be printed on the surface forming the

  opposite end of the package and o the hinged cover is arranged, placing commercial information on one

  future end walls of the package determine the direction

  information to be listed on the surface of the

  side to be visible together with the wall of ex-

  tremité on the shelves of the stores.

  Since the end where the hinged lid is located forms the natural top of the package, the consumer

  will normally place the package with this top, and

  with the opening, towards the top, with the result that

  important information concerning the goods,

  written on the side surfaces of the packaging, will be

  look upside down and, therefore, will be illegible.

  The object of the present invention is to provide a bag

  intended for automatic packaging, which does not present the in-

mentioned above.

  The bag according to the invention is characterized in that it is formed practically in one piece with an anterior or front part, a rear part and a bottom, the front parts and

  are welded together along the edges, in the direction

  the longitudinal axis of the bag, in that a transverse band

  dirty is disposed at the free end of the front part of the bag, and is attached thereto by the welds of the edges of the bag, and is also joined to said end portion, at least, along its edges to welding, and in that, after filling, the bag is intended to be closed by a weld,

  after which, it can be opened by breaking these points of

  hard and possibly other closures.

  Unlike the previous measures, the information

  can now be printed on the natural background

  The result of this is that the information on the ribs of the latter can be oriented so as to be bound on the shelf of the store, together with the

  information written on the bottom of the package, while being correctly placed when the packaging is oriented with the background

down.

  The invention will now be described in more detail with reference to the embodiments shown in the accompanying drawings, in which: FIG. 1 represents a package of the kind of

  to which the invention relates, but which is a way of

  already known; Figure 9 shows the package of Figure 1 in another position; Figure 3 shows a bag according to the invention flat; Figure 4 is a sectional view along the line IV-IV of Figure 3; Figure 5 is a sectional view similar to Figure 4, but relating to a slightly modified bag; and,

  Figures 6 and 7 illustrate a bag according to the invention.

  The bag shown in FIGS. 1 and 2 is made of a thermoplastic material. This bag comprises a front portion 1 and a rear portion 2 which are united by weld seams 3. The rear portion 2 extends to form the top 4. of the bag, as well as an articulated lid 5 which is

  born, as can clearly be seen in Figures 1 and 29 to

  border on the front part 1 The cover 5 is welded at 6 to the weld seam 3 Figure 1 shows how the

lid opens.

  The filling of the bag shown on the fibers 1 and 2 takes place from the small end (of the bottom), which is then closed by a weld seam (not shown). These packages are normally placed on shelves, as shown in Figure 2, so that we see a small end and a

  Since the closure of the bag takes place at the base of the bag, it is clear that commercial information can not be printed on it beforehand and that the top of the packaging must contain this information The disadvantage that this represents is visible in Figure 1 where we see that the information on the side of the packaging is oriented upside down when the bag is placed with its natural top

  The blank for producing a bag according to the invention,

  shown in FIGS. 3 and 4, is formed of a piece of

  The front and rear portions are welded along the edges oriented in the direction of the longitudinal axis of the bag. As can be seen clearly in FIG. previous is a little shorter than the part

  placed a transverse band 10 which is attached to the welds of the edges of the bag and also, with the aid of welding points, along its lengths 11 and 12 Two holes 13, 14 to suspend the bag blank in the machine 'packaging are provided in the,

  upper region of the rear part a.

  The filling of the bag takes place in the direction of the arrow B of Figures 3 and 4 and is closed by welding together the upper edge of the strip 10 and the rear portion 8, the portion extending above the weld seam At the same time, being cut in the packaging thus formed, the strip 10 serves as a movable lid time after the soldering points 11, 12

  The bag blank shown in Figure 5 looks like

  much to that of Figure 4, so that the details cor-

  The front portion 8 has a perforation 15 extending

  in the lateral direction of the bag, under the band 10.

  The front end of the embodiment represented on the

  5 is that the bag is completely closed until the perforation has been broken, which, of course, is essential

hygienic point of view.

  The packs obtained with the blanks of FIGS. 3-5 are shown in FIGS. 6 and 7. The pack shown in FIG. 6 is standing upwards with the above, ie with the openable lid formed by the band. 10 top Since the weld bead, designated 16 in FIG. 6, is at the top, the goods information can be

  all around on the side surface.

  It goes without saying that many modifications can be made to the exemplary embodiments represented E and described,

  without departing from the scope of the invention.

  Thus, for example, the transverse band 10 6 '

  could be placed on the inner face of the border

  7 and could extend over a certain distance above the upper edge of this part as is the case in FIG. 4. The band 10 could also be placed inside the front part 7 with its edge at the same level
