DETAILED DESCRIPTION

(15) FIG. 1 shows a first exemplary embodiment of a base body 11 of a packaging 10 (see FIG. 2) for receiving cigarette sheath paper sheets 12, wherein the packaging 10 comprises a compartment 16 for cigarette sheath paper sheets 12. In order to have a better view, the closing flap 40 (see FIG. 2) is not shown here which in combination with the base body 11 constitutes the packaging 10.

(16) In this embodiment, the cigarette sheath paper sheets 12 are provided as a folded cigarette paper band 18, wherein the paper band 18 is at least twice as long, preferably at least ten times as long and more preferably at least twenty five times as long as the length of a cigarette to be manufactured.

(17) Based on FIG. 1 definitions for the different extensions or directions for an eased understanding when explaining the exemplary embodiments according to the invention are made. A transverse extension B, a longitudinal extension L and a vertical extension H are thus defined. It is understood that these definitions can also be chosen differently and do not limit the scope of protection in view of this chosen nomenclature. An opening 20 of the compartment 16 extends along the longitudinal extension L or transverse to the transverse extension B. In other words, the extension of the opening 20 in the direction of the longitudinal extension L is larger than the extension of the opening 20 in the direction of the transverse extension B.

(18) The base body 11 and the closing flap 40, not shown here, are made of cardboard and is provided as one integral piece as will be explained further down.

(19) FIG. 2 shows a first exemplary embodiment of a packaging 10 for receiving cigarette sheath paper sheets 12. The packaging has the base body 11 as shown in FIG. 1 and a closing flap 40. The closing flap 40 has a substantially shape-retaining bent end area 42 which has such dimensions and is configured such that the end area 42 reaches around a front surface 44 of the base body 11 at least partially in the closed state of the packaging 10.

(20) The closing flap 40 is an extension in the direction of the longitudinal extension L and extends along the full transverse extension B. The end area 42 reaches around the front surface 44 of the packaging 10 in the closed state and thus keeps the closing flap 40 closed. The sheath paper 12 is thus protected.

(21) The opening 20 of the compartment 16 extends along the transverse extension B or transverse to the longitudinal extension L. In other words, the extension of the opening 20 in the direction of the transverse extension B is greater than the extension of the opening 20 in the direction of the longitudinal extension L.

(22) The end area 42 comprises a cross section along a vertical extension H in the shape, at least substantially, of a half ellipse, wherein the height of the cross section is greater than the width of the cross section. The end area 42 comprises an end edge 46. The end area 42 further comprises a recess 48 which is open towards the end edge 46, so that the end area 42 does not reach around the front surface 44 in the area of the recess 48.

(23) The closing flap 40 is connected to the base body 11 via a first bending area 50, which is configured to lead the closing flap 40 around a further front surface of the base body 11 in a bent manner. Since the closing flap 40 is configured as a single closing flap 40, the further front surface 52 around which the closing flap 40 is led, opposite to the front surface 44 which the end area reaches around.

(24) FIG. 3 shows a further exemplary embodiment of a packaging 10 for receiving single cigarette paper sheets 12 or a cigarette paper band 18, wherein the closing flap 40 comprises at its free end a reinforcement area 84 with an insertion flap 92 and wherein the closing flap 40 comprises two insertion slits 94 which are configured to receive the insertion flap 92. The reinforcement area 84 is flipped backward and is held in the insertion slits 94 with its insertion flap 92. Due to the insertion an additional binder can be omitted. The possibility of producing the packaging integrally, i.e. as one piece, is disclosed by the paper pattern shown in FIG. 14.

(25) FIG. 4 shows a further exemplary embodiment of a packaging 10, wherein a typical filter paper block 15 is folded into the base body 11 of the packaging 10. Here, a sheet 19 of the filter paper block 15 is folded such that it is hooked behind a side part 80 of the packaging 10.

(26) FIG. 5 shows the exemplary embodiment of the packaging 10 according to FIG. 4 when the compartment 16 is swung in.

(27) FIG. 6 shows the exemplary embodiment according to FIG. 5 in the closed state.

(28) FIG. 7 shows the exemplary embodiment according to FIG. 6 in the opened state from a different perspective.

(29) FIG. 8 shows the exemplary embodiment according to FIG. 6 in the opened state from a different perspective.

(30) FIG. 9 shows a further exemplary embodiment of a packaging 10. The shown packaging 10 corresponds substantially to the packaging 10 shown in FIG. 2. Here, however, the closing flap 40 is configured as an extended closing flap 40. Thus, the closing flap 40 comprises a second bending area 60, which is configured to lead the closing flap around the further front surface 52 of the base body in a bent manner. The closing flap 40 comprises a first section 62 and a second section 64 which each have a transverse extension B and a longitudinal extension L which correspond at least substantially to the transverse extension B and the longitudinal extension L of the base body.

(31) In particular, the closing flap 40 is therefore configured so that the closing flap 40 along the longitudinal extension L transitions after the first bending area 50 into the first straight section 62, the first straight section 62 transitions into the second bending area 60, the second bending area 60 transitions into the second straight section 64 and the second straight section 64 transitions into the end area 42. The packaging 10 can thus be put down such that the closing flap 40 and the base body 11 show at least substantially the shape of a triangle when viewed from the side.

(32) The end area 42 also has an end edge 46 which runs along the transverse extension B and establishes the end of the closing flap 40. The closing flap can be bent along the bending area 50 (see FIG. 2) or along the bending areas 50, 60 (see FIG. 4) such that at least a part of the base body 11 comes to rest on the end edge 46.

(33) FIG. 10 shows the second exemplary embodiment according to FIG. 4 in a perspective view from the side. It can be seen that the base body 11 is raised above a support surface 66 of the packaging 10. The side with the front surface 44 is raised because the first bending area 50 maintains its round shape also in the partially opened state due to the inherent stability of the material.

(34) In this context it is advantageous if an abutment edge 68, which runs in a direction of the transverse extension B and which connects the closing flap 40 to the base body 11, sits at a distance from the front surface 44 along the longitudinal extension L. The side with the further front surface 52 is raised, because the base body 11 rests on the end edge 46. Should a liquid flow onto the support area 66, the base body 11 is protected from moisture.

(35) FIG. 11a shows the packaging 10 according to FIG. 2 in a view from the side.

(36) In FIGS. 11b to 11e it is shown that the closing flap 40 with the end area 42 is configured such that the end area can only be pushed over the front surface 44 undergoing a slight deflection against an elastic counter force when opening or closing the packaging 10.

(37) FIG. 11b shows the state of the packaging 10 when the closing flap 70 is led relatively loosely around the base body 11. It is noted that not all reference numerals that have been previously introduced are repeated in order to not obscure the disclosure. However, all reference numerals remain valid like they have been introduced and used before. Further, it is noted that while FIGS. 11b to 11e show the process of closing, they also disclose—when reversing the sequence of the figures—the process of opening the packaging 10.

(38) FIG. 11c shows that the second straight section 64 pivots, at least substantially, around a imaginary pivot axis 70 during opening and closing of the packaging 10. The closing flap 40 is now pulled somewhat tighter against the base body 11. It can be seen that in particular the bending in the area of the front surface 44 lies tight.

(39) When opening and closing the packaging, the end edge 46 moves on a first radius R1 around the pivot axis 70. Further, point 72 of the end area 42, which lies the farthest away from the pivot axis 70, moves on a second radius R2 around the pivot axis. Finally, a point 74 of the front surface 44, which lies the farthest away from the pivot axis 70, lies on a radius R3.

(40) It is shown how the end area 42 with the end edge 46 glides onto the front surface 44 during closing. FIG. 11d shows that the closing flap 40 is slightly deflected in an area adjacent to the end area 42. This allows for the end area 42 to further glide over the front surface 44. The end edge 46 moves beyond the point 74 on the front surface 44.

(41) In general it is also possible that the end area 42 undergoes a slight deflection. During practical experiments, however, it was found to be beneficial if the bending takes place substantially in the closing flap 40, here in the second straight section 64. The closing flap 40 is now pulled against the base body 11.

(42) FIG. 11e shows the situation when the closing flap is closed. The elastic counter force which was created by the bending of the closing flap 40 (perhaps also by the end area 42) now provides for bringing the closing flap 40 with the end area 42 back into its original shape. The packaging 10 is now closed and can only be opened again by applying a force. The closing flap 40 relaxes slightly and preferably pulls the end area 42 against the front surface 44.

(43) FIG. 12a shows again the packaging 10 according to FIG. 4 in a view from the side. In the following disclosed alternative process of closing an advantage is achieved in that the packaging 10 is resilient and has a elongate closing flap 40 instead of a hinge. Initially, the basic state is shown. It is pointed out that the process of closing shown in FIGS. 12a-12d can also be applied to the packaging 10 shown in FIG. 2. It is further pointed out that the process of closing shown in FIGS. 11a-11e can also be applied to the packaging 10 according to FIG. 4.

(44) FIG. 12b shows how the closing flap 40 tightens around the base body 11 due to the pressure force 45 as indicated by the arrow 47. The end area 42 therefore moves downwards as well as to the right when referring to the orientation shown in the drawing. FIG. 12c shows how the movement progresses. When the closing flap 40 finally reaches its end position, see FIG. 12d, the pressure force 45 ceases due to the fact that the user does not press the closing flap 40 anymore. The closing flap 40 then moves in the direction of the arrow 47′ back into the relaxed position.

(45) The movement of the closing flap 40 is substantially achieved in that the closing flap 40 tightens against the base body (arrow 47) under the influence of the pressure force 45 and relaxes (arrow 47′) when the pressure force 45 ceases. Also in this context it is pointed out that FIGS. 12a to 12d show the process of closing, however, at the same time—when viewing the sequence in reverse—disclose the process of opening the packaging 10.

(46) In FIGS. 13a to 13e further exemplary embodiments of packagings 10 are shown where the respective front surface 44 and end area 42 are configured differently. Each of said figures shows in a first representation the respective packaging 10 in a side view and in a second representation a magnified view of the end area 42 of the closing flap 40.

(47) The packaging 10 shown in FIG. 13a is the exemplary embodiment known from FIG. 4. The cross section along a vertical extension H of the closing flap has substantially the shape of a half circle, wherein the height h of the cross section is greater than the width b of the cross section.

(48) FIGS. 13b to 13d show exemplary embodiments where the cross section has substantially the shape of a U. The exemplary embodiments differ in that the curves of the U become less and less pronounced.

(49) In FIGS. 13a to 13d the front surface 44 was chosen such that it corresponds to the shape of the end area 42 and vice versa. This allows for a good form fit. The exemplary embodiments that have the curves of the U less pronounced are believed to be less preferred, since the effect of gliding onto, as it is shown in FIGS. 11b to 11e, is more difficult for such shape. However, depending on the design goal, such embodiment can be preferred if a particularly good form fit is desired. Further it can be advantageous if the contour of the front surface 44 is designed asymmetrically, so that the end area 42 glides over a round surface during closing, but has to be lifted over an edge for opening.

(50) Finally it is shown in FIG. 13e that the shape of the end area 42 does not have to correspond to the contour of the front surface 44. Such embodiment is encompassed by the invention, even though it is believed today to be less preferred.

(51) FIG. 14 shows a paper pattern that allows for an integral manufacture of the packaging 10. The paper pattern is bent along the parallel dashed lines, and the side parts 80 and 82 are inserted. The area 84 is used as a material reinforcement for the end area 42. It is flipped back and thereby doubles the material thickness in the end area 42. Other kinds of reinforcement can also be chosen.

(52) The closing flap 40 comprises at its free end a reinforcement area 84 with an insertion flap 92. The closing flap 40 further comprises at least one insertion slit 94, here two insertion slits 94, which are configured to receive the insertion flap 92, so that the reinforcement area 84 can be flipped back and can be held in its insertion slit 94 or in its insertion slits 94 with its insertion flap 92.

(53) The paper pattern offers a good possibility to implement the packaging 10 according to the invention. When producing a real-life model, disclosed advantages of the invention can be understood well. Further, based on such model, further advantages and special characteristics of the packaging 10 according to the present invention are disclosed.

(54) FIG. 15a shows in a side view an exemplary embodiment of the packaging 10, where the closing flap 40 is manufactured in one layer in full.

(55) FIGS. 15b-15g show exemplary embodiments of the packaging 10, where the closing flap 40 starting from the end area 42 comprises a section that comprises at least two layers. The section is preferably embodied as one integral piece. The dashed line in FIG. 15g indicates that the section can extend over and beyond the bending area 50.

(56) FIGS. 15h-15k show exemplary embodiments of the packaging 10, wherein the closing flap 40 starting from the end area 42 comprises a section with a material in at least two layers, which leads to the first bending area 50 and which is configured between the first bending area 50 and the base body 11 as a spring area 77, so that it pushes the first bending area 50 away from the base body 11 in the manner of a spring and thus pushes the end area 42 against the front surface 44.

(57) FIG. 16a shows a further exemplary embodiment of a packaging 10 wherein the closing flap 40 is configured such that in the closed state of the packaging 10 a section 64 of the closing flap 40, which is adjacent to the end area 42, has in the vicinity of the end area 42, see arrow 98, a smaller distance to the base body 11 than at a location 99 of the section 64 which is farther away from the end area 42. In this exemplary embodiment the closing flap 40 is flipped over the base body 11.

(58) FIG. 16b shows a further exemplary embodiment of a packaging 10 which corresponds to the exemplary embodiment according to FIG. 15a with the exception of the bending area 50.

(59) FIG. 16c shows a further exemplary embodiment of a packaging 10 where in the closed state of the packaging 10 a section 64 of the closing flap 40, which is adjacent to the end area 42, has in the vicinity of the end area 42, see arrow 98, at least substantially the same distance to the base body 11 as at a location 99 of the section 64 that is farther away from the end area 42.

(60) FIG. 16d shows a further exemplary embodiment of a packaging 10, which corresponds to the exemplary embodiment according to FIG. 15c with the exception that the closing flap 40 is flapped twice over the base body 11.

(61) FIG. 16e shows a further embodiment of a packaging 10, which corresponds to the exemplary embodiment according to FIG. 15d, with the exception that the closing flap 40 is configured such that in the closed state of the packaging 10 a section 64 of the closing flap 40, which is adjacent to the end area 42, has in the vicinity of the end area 42, see arrow 98, a smaller distance to the base body 11 as at a location 99 of the section 64 that is farther away from the end area 42.

(62) What has been described above are preferred aspects of the present invention. It is of course not possible to describe every conceivable combination of components or methodologies for purposes of describing the present invention, but one of ordinary skill in the art will recognize that many further combinations and permutations of the present invention are possible. Accordingly, the present invention is intended to embrace all such alterations, combinations, modifications, and variations that fall within the spirit and scope of the appended claims.
