Description

  The present invention relates to packets for elongated shaped articles such as cigarettes, rod-shaped chewing gums and snout pouches.

  Packets or wrappers of the type described above are formed from substantially rectangular leaves with a flexible packaging material that is highly impervious to air and moisture, and in the form of a substantially parallelepiped. And has a rectangular cross section.

  The packet consists of four side walls extending parallel to the long axis of the parallelepiped, i.e. the front wall, the back wall or the back, two narrow walls or sides, two walls across the long axis, i.e. the top surface It is formed by the wall and the lower wall which is the bottom.

  This type of packet is the subject of USP 4,300,676, which discloses a cigarette-containing packet that is inserted into an outer wrapper with a box-shaped cardboard with a hinged lid.

  Cigarettes in the packet are placed side by side parallel to the long axis of the box.

  The top of the packet has a substantially U-shaped contour notch and extends through the front wall from both ends of the acute angle center that occupies the front wall and along the front wall to the top of the back surface. Includes two parallel parts.

  The notch forms a closure element on the wrapper that resembles a flap or tongue that is positioned over an opening from which the user can pull the article in the packet by pulling on one end.

  The closure element and the area around the closure element are completely covered by an adhesive label across the area including the top of the front wall, the top of the packet, and the back adjacent.

  The label portion positioned on the front wall includes a tab that facilitates tongue pullout and allows the user to reclose the packet upon removal of the cigarette or other article.

  Importantly, to ensure that the adhesive label completely covers the entire area occupied by the notch, and consequently ensures a hermetic chain of the wrapper, the parallel part of the notch is connected to the front wall of the packet, The top surface and the back surface are installed at a predetermined distance from the corner edge joining the two side surfaces.

  This is because the top surface of the packet as a whole is exposed to expose the upper end of all the articles contained in the packet when the closure element is pulled out, as opposed to the case where the conventional hinged lid packet is opened. It means not going up.

  As a result, an article whose upper end is located at the two ends of the top surface and is outside the notch line is not exposed and cannot be seen. Furthermore, the endmost article becomes difficult to access and remove when the contents of the packet are tightly fitted and totally surrounded by the wrapper.

USP 4,300,676

  The object of the present invention is to make it possible to remove all of the articles contained in the packet without the typical disadvantages of the conventional packets mentioned above, and to be cost-effective compared to packets with conventional hinged lids.

  Referring to FIGS. 1, 2, 3 and 6, reference numeral 1 indicates the entire packet which serves to accommodate a group of cigarettes 2 arranged side-to-side parallel to the long axis A of the packet.

  In the embodiment of FIG. 3, the articles 2 are shown as cigarettes 3 arranged in three rows 4, and in the embodiment of FIG. 6, the packet 1 contains a group of cigarettes arranged in two rows. As is obvious, the article 2 may be, for example, a rod-shaped chewing gum 5 (FIG. 13), a snuff pouch (FIG. 11), or the like.

  Packet 1 manufactured on a cigarette packer or other packaging machine (not shown) has a substantially parallelepiped appearance and rectangular cross-section, is highly impervious to air and moisture and typically heat sealed It includes an outer wrapper 7 formed by a possible bendable material.

  The wrapper 7 is formed by four side walls parallel to the long axis A and is a front wall 8, a rear wall or back surface 9, two relatively narrow walls or side surfaces 10 as well as two walls crossing the long axis A. It is formed by an upper wall shown as surface 11 and a lower wall shown as bottom surface 12.

  The top of the wrapper 7 has a substantially U-shaped notch 13, which is a central part 14 occupying the front wall 8, and from the opposite ends of the central part 14 to the front wall 8, top face 11, and rear face 9. It includes two parallel portions 15 extending over the top.

  On the back surface 9 of the wrapper, the two free ends 16 of the parallel part 15 are curled in the mutual direction.

  The U-shaped notch 13 forms a closing element or tongue 17 corresponding to the opening 18 for removing the article 2 from the packet 1.

  The part of the wrapper 7 with the notch 13 is covered by an adhesive label 19 and the part located on the front wall 8 is a tab designed to facilitate the operation of pulling out the tongue 17 when opening the packet. 20.

  The packet 1 includes an inner element 21 made of a rigid or semi-rigid paper material. The inner element 21 is interposed between the article 2 and the outer wrapper 7, contacts the front wall 8, and has the same height as the front wall 8. And a flat central portion 22 having a width (see FIGS. 15 and 16).

  Inner element 21 has ribs 23 along each longitudinal edge having a depth equal to the depth of wrapper 7 and more precisely a width corresponding to the lateral width provided by side 10 of packet 1. Thus, the rib 23 occupies two substantially parallelepiped spaces inside the wrapper 7, each of which corresponds in cross section to the portion of the top surface 11 between the notch 13 and the side surface 10.

  Referring to FIG. 4, the inner element 21 is a flat having a substantially substantially rectangular outer shape formed symmetrically with respect to the major axis A ′ and divided into a plurality of panels by fold lines in the longitudinal direction and the transverse direction. It is formed from a blank 24.

  More precisely, the blank 24 is connected to the second, third and fourth panels 30, 31 and 32 and their respective end flaps 33 by means of four longitudinal crease lines 25, 26, 27 and 28 on both sides of the central panel 29. Divided.

  Finally, the single crease line 34 forms a bottom flap that traverses one end of the central panel 29, traverses the long axis A ', and contacts the bottom surface 12 of the assembled packet 7.

  The edge 36 of the central panel 9 remote from the bottom flap 35 has a U-shaped notch 37 to facilitate removal of the article 2 from the panel. In this case, the two end flaps 33 have correspondingly shaped cutouts 38.

  In the flat blank 24 panel and flap creation method, the inner element 21 is formed by folding along the respective crease lines. The continuous folding process will be easily understood from the drawings.

  In particular, adjacent panels 30, 31 and 32 are joined with a portion of the central panel 29 along each of the two longitudinal edges forming the central panel 29 to form one longitudinal wall of the rib 23. More precisely, the second panel 30 is an outer wall that contacts the corresponding side surface 10 of the wrapper 7, the third panel 31 is a wall that contacts the back surface 9, and the fourth panel 32 is a wall that faces the inside of the packet 1. And comes into contact with the article 2.

  After being bent into a predetermined shape, the inner element 21 is fixed by sticking two end flaps 33 to the central panel 29 with an adhesive so that the flat central portion 22 is doubled.

  The inner element 21 is supplied to the packaging machine by stacking flat blanks up and down (see FIG. 14), and when assembled together with the wrapper 7, it is finally formed in a form as shown in FIGS. .

  FIG. 15 shows a blank 39 that is different from the blank 24 described above, which includes another panel 40 that is coupled to the bottom flap 35 along a transverse fold line 41 on the opposite side of the central panel 29.

  One side of the panel 40 is designed to contact and engage the back surface 9 of the wrapper 7, and the other side of the panel 40 is designed to contact the third panel 31 having two ribs 23.

  Another difference between the blank 39 of FIG. 5 and the blank 24 of FIG. 4 is that the two third panels 31 have a substantially L-shaped appendage 42 at both ends adjacent to the additional panel 40. It is.

  When bent at right angles to the two respective panels 31, the appendage 42 forms a closing element corresponding to the open end provided by the rib 23 of the inner element 21.

  FIG. 6 shows the packet 1 designed to house two rows of cigarettes 3, the blank 44 shown in FIG. 7 being in contact with the blank 39 of FIG. 5 and the additional panel 40 contacting the side 10 of the outer wrapper 7. Would be different in that it comprises two side flaps 45 each formed by a crease line 46.

  Furthermore, the free end of the panel 40 has a notch 37 designed to facilitate the removal of the article 2.

  FIGS. 8 and 9 show a panel that houses a snug pouch 6 placed over the edges and parallel to the front wall 8 and the rear wall 9.

  The blank 47 shown in FIG. 10 differs substantially from the blank 44 in FIG. 7 in that the notches 37 in the panels 40 and 29 are dissimilar in size and are not axially aligned with each other. .

  FIG. 11 shows another packet 1 containing a cigarette pouch 6 stacked on the edge in a direction across the front wall 8 and the rear wall 9.

  The blank 48 shown in FIG. 12 is substantially similar to the blank of FIG.

  FIG. 13 shows a packet 1 holding a bar-shaped chewing gum 5 that is superimposed on the edge in a direction across the front wall 8 and the rear wall 9.

  Obviously, in packet 1 with the illustrated inner elements, the problems with the prior art relating to user access and extraction to the item closest to the side wall of the wrapper are totally eliminated.

  The quality and strength of the packet can be selectively determined based on the type of blank used for the inner element 21.

  The position of the inner element 21 in the wrapper 7 is equally rotated by 180 ° around the major axis A ′ from the position shown in the attached drawings. That is, the flat central portion 22 thereby contacts the back surface 9 of the wrapper 7.
