Description

The present invention relates to a hard pack for tobacco products.
In particular, in the following description, reference is made to a tobacco product composed of a group of cigarettes enclosed by an inner package typically made of metal foil paper.

  A pack of this type is formed from a pre-creased flat punched blank and is connected to the rear edge of the container and serves to close the open upper end of the container; And a reinforcing frame that projects partially to provide an element that is partially installed inside and that holds the lid in a stable closed position.

  Once these hinged lid packs are opened, the lid is properly stabilized while the pre-consumer cigarette remains, even if the reinforcement frame generally has a retaining element along the corner edges. Experience some problems to keep it closed.

  Thus, further considering that a portion of the inner package is removed first, the group of cigarettes cannot be adequately protected, resulting in product degradation due to the resulting loss of aroma and moisture content.

  In FIGS. 1 to 6 of the accompanying drawings, 1 is designed to include a tobacco product composed of a group 2 of cigarettes 3 (see FIGS. 3 and 4) enclosed by an inner package 4 made of metal foil paper. The whole pack of 1st Embodiment is shown.

  The pack 1, which has a substantially parallelepiped appearance with respect to the longitudinal axis A extending parallel to the axis of the cigarette 3, includes an inner box member, ie, a packet 5, and an outer box member, ie, a case 6.

  The inner box member 5 consists essentially of a hinged lid packet and includes a container 7 and a lid 8 connected to the container 7 along a first hinge line 9 extending across the axis A.

  The container 7 has two pairs of four longitudinally arranged parallel side walls forming a front wall 10 and a rear wall, i.e. a rear face 11 (Fig. 6), connected to each other by two side walls 12, One end of the space surrounded by the four walls is closed by the bottom wall 13.

  The other end of the container 7 is closed by a lid 8, which occupies the same plane as the upper end wall 14 parallel to the bottom end wall 13, the rear surface 11 of the container, and along the first hinge line 9. And a rear wall 15 connected to each other and two triangular side walls 16 occupying the same plane as the side surfaces 12 of the container 7.

  The lid 8 is pivotable about a hinge 9, and when in the closed position shown in FIG. 1, the free edge provided by the side wall 16 and the top wall 14 of the lid 8 described above is connected to the side surface 12 of the container 7. Arranged in contact with the corresponding free edges respectively provided by the front wall 10.

  The outer box member or case 6 crosses the longitudinal axis A with two longitudinal walls 18 that are rigidly joined around the four sides of the back wall 17 in addition to the main rectangular back wall 17 (FIG. 6). And two walls 19 to be arranged.

  The outer box member 6 has a recess 20 (FIG. 6). The recess 20 has a rear wall or back surface 11 of the packet 5 in contact with a rear wall 17 of the outer box member and a bottom end wall 13 on one side. The packet 5 is accommodated in an arrangement that contacts the directional wall 19, the upper end wall 14 contacts the other lateral wall 19, and the side surface 12 contacts the longitudinal wall 18 of the outer box member.

  The depth of the outer box member, that is, the case 6 is substantially equal to the depth of the packet 5 in which the lateral width of the side surface 12 is measured.

  The packet 5 is hinged to the free edge provided by the corresponding lateral wall 19 of the outer box member 6 along the corner edge connecting the front wall 10 and the bottom end wall 13 to form the second hinge line 21. 1 between the fully housed first position shown in FIG. 1 and the second position shown in FIG. 4 with part of the packet pulled out of the recess and the pack 1 fully open. It becomes possible to rotate around these same edges.

  A movement limiting coupling means 22 is arranged between the longitudinal wall 18 of the outer box member 6 and the side surface 12 of the packet 5, by which the packet 5 rotates on the second hinge line 21 within a predetermined rotation angle. Allowed to do. This movement limiting coupling means 22 includes a pair of tabs 23 which are formed by cuts 24 provided in each side surface 12 and whose free ends project towards the front wall 10 of the packet. Each tab 23 is designed to engage an adaptively shaped edge of the anti-turn 25 formed by the inner surface of the corresponding longitudinal wall 18 so that the pack 5 is second as shown in FIG. Angular movement within a limited range is allowed when rotating around the hinge line 21.

  A second coupling means 26 is arranged between the upper wall 14 of the lid 8 and the corresponding lateral wall 19 of the case 6, and automatically rotates when the packet 5 rotates away from the recess of the case 6. The lid 8 is opened. The second coupling means 26 is formed by a notch 28 and has a single tab 27 protruding from the free edge of the lateral wall 19 toward the back wall 17 of the case 6, and the upper wall 14 and the rear wall 15 of the lid 8. Includes two slots 29 and 30, respectively.

  The slots 29 and 30 serve to form a web 31 that coincides with the corner edge to which the two walls 14 and 15 of the lid are connected.

  As can be seen in FIG. 5, when the packet 5 is rotated and taken out from the outer box member 6, when the tab 27 comes to the position of the slots 29 and 30, it slides into the slot and engages the web 31. As seen in FIG. 5, the lid 8 rotates counterclockwise around the associated hinge line 9.

  As shown in FIGS. 2 and 6, the main back wall 17 of the case 6 allows the user to easily remove the packet 5 from the case 6 so that the lid 8 automatically opens with the back of the packet 5. 11 has a circular opening 32 that allows contact with the 11.

  In the pack shown in FIG. 7, the packet 5 does not have the hinged lid 8, but instead, the upper lateral wall 19 and a part of the rear wall 17 of the outer casing member 6 perform the function that the lid of FIG. 1 performs. This is different from the pack shown in FIG.

  In the embodiment of FIG. 7, instead of pushing the back surface 11 of the packet through the opening 32, the packet 5 is pulled out of the recess 20 by pulling the tab 33 connected to the front wall 10. Then, when this solution is applied to the packets of FIGS. 1-6, the hinged lid 8 automatically opens in a similar manner.

  In a further embodiment of the pack (not shown), the hinged lid 8 may be a conventional design having a front wall that occupies the same plane as the front wall 10 of the packet. In this example, the two side walls 16 exhibit a trapezoidal outline rather than a triangle.

  8 and 9, 5 'and 6' show two flat blanks of packaging material, which are subjected to a series of folding steps to produce an inner box member, ie packet 5, and an outer box member, ie case. 6 is formed.

  In the following description of the components of the blanks 5 'and 6', at least some of the reference numbers used are the same as those already used to indicate the corresponding portions of the two box members 5 and 6.

  The blank 5 of FIG. 8 has a substantially rectangular outline and is divided into a plurality of panels by crease lines that extend parallel to each other across the longitudinal axis A ′.

  Two panels 10 'and 11' corresponding to the front wall 10 and the back surface 11 of the packet respectively, and a panel 13 'positioned between the two panels and corresponding to the bottom end wall 13 are arranged on the longitudinal axis A'. Is done.

  The panel 10 ′ is connected to a flap 10 ″ that is folded twice and flattened to the limit along the crease line far from the intermediate panel 13 ′.

  The panel 10 'is connected to the two side panels 12' on both sides in the longitudinal direction along the associated crease line.

  Similarly, the panel 11 'is connected to the two side panels 12 "on both longitudinal sides along the associated crease line.

  The panels 12 ′ and 12 ″ are overlapped and fixed together to form the above-described side surface 12 of the inner box member 5.

  Panel 11 'is separated from further panel 15' by a crease line 9 'coinciding with lid hinge line 9 and further panel 15' is separated from end panel 14 'by an associated crease line.

  The two panels 15 'and 14' coincide with the rear wall 15 and the upper wall 14 of the lid 8, respectively.

  Two triangular flaps 16 'separated from each side panel 12' 'by diagonal notches are joined to both ends of the panel 15', separated from the panel by respective crease lines, and cross the longitudinal axis A '. Arranged on the axis.

  The two flaps 34 are connected to the two ends of the side panel 12 '' far from the triangular flap 16 'through respective crease lines, and connect the side surface 12 and the bottom end wall 13 of the inner box member 5 to each other. Play a role.

  Similarly, the two flaps 35 are connected to the two triangular flaps 16 ′ through respective crease lines, and serve to connect the upper wall 14 and the rear wall 15 of the lid 8 to each other.

  The side panel 12 ″ has a notch 24 ′ that serves to form a tab 23 ′ that forms part of the motion limiting coupling means 22 described above.

  Finally, the panels 15 'and 14' have respective slots 29 'and 30' that form part of the coupling means 26 shown in FIG.

  The blank 6 ′ in FIG. 9 is divided into a plurality of panels by crease lines that run parallel to each other across the longitudinal axis A ″.

  A central rectangular panel 17 'providing a circular opening or hole 30' is connected to the two side panels 18 'via a longitudinal crease line that coincides with the longitudinal side and a transverse crease line that coincides with the lateral side. Connected to two further panels 19 '.

  The central panel 17 ′ coincides with the back wall 17 of the outer box member 6, and the adjacent panels 18 ′ and 19 ′ coincide with the longitudinal wall 18 and the lateral wall 19.

  Next, the side panel 18 ′ is reinforced to reinforce the longitudinal wall 18 and to form a detent 25 that engages the tab 23 of the motion limiting coupling means 22 by the action of each adaptively shaped longitudinal edge. Are connected along respective longitudinal crease lines to corresponding end panels 25 ′ that are double folded and flattened to the extreme for each panel 18 ′.

  A panel 36 connected to the lateral upper panel 19 ′ along each crease line is designed to function as a reinforcing element for the associated lateral wall 19. The panel 36 also has a notch 28 ′ shaped to form a tab 27 ′ which is formed by the slots 29 and 30 of the lid 8 each time the pack 1 is opened. Interacting with 31 provides the coupling means 26 described above.

  The blank 6 ′ also has a substantially trapezoidal contoured flap 37 connected to the transverse panel 19 ′ at the bottom of the blank, as seen in FIG. And the flap 37 is fixed to the bottom of the container 7 with an adhesive to provide an element for connecting the outer box member 6 and the inner box member 5 to each other.

  The two flaps 38 are connected to the end of each longitudinal panel 18 ′ along the respective crease lines, and the longitudinal wall 18 and the lateral wall 19 of the outer casing member 6 are connected to each other via the flap 38. .

  The main advantage provided by the pack 1 described and illustrated above is that when the packet 5 is received in the recess 20, the lid 8 is kept in the correct closed position, resulting in a completely sealed state, The condition is that it can be maintained for as long as there is a product to be consumed.

  A further advantage is that the lid 8 automatically opens when the packet 5 is removed from the recess 20.

  Finally, it will be appreciated that the pack 1 embodied in accordance with the present invention is economically manufactured by providing the packet 5 and case 6 with at least one rounded or chamfered longitudinal corner edge. Further advantages can be provided in addition to those already mentioned.

  In essence, the above specification and the accompanying drawings include an inner box member or casing 6 characterized by the cigarette outer box or case 6 and the hinged lid design shown in FIG. 1 or the lidless design shown in FIG. The packet 6 and both the case 6 and the packet 5 have a sharp corner edge, but with respect to the pack 1, the teachings of the present invention are (in accordance with an embodiment not shown) longitudinal and / or transverse direction It can be equally applied to any type of inner box member or outer box member formed by rounding or chamfering at least some of the corner edges. For example, the longitudinal corner edges may be rounded or chamfered without having a right-angle shape, or similarly (when the cigarette packet design disclosed in US Pat. The lateral wall 19 and the rear wall 17 of the case 6 may be connected to each other and the upper corner 14 and the rear surface 11 of the packet 5 may be rounded or chamfered without forming a right angle. Also, some of the longitudinal corner edges and of the transverse corner edges so that both the longitudinal and lateral corner edges have rounded or chamfered corner edges rather than sharp corner edges. Some may be rounded or chamfered without being rectangular.

  Finally, when another type of embodiment (not shown) is employed, both the outer case 6 and the inner packet 5 can have the shape of a cigarette packet disclosed in Patent Document 2. In this case, the back surface 17 of the case 6 and the main surfaces 10 and 11 of the packet 5 have a convex shape, each having a flat central portion and two creased curved side portions, and this creased curved side. The side is connected to the case and the side of the packet along an acute, longitudinal corner that is joined to the flat center on one side and not pointed on the other.
