Description

  The present invention relates to a cigarette rigid packet.

  In the following description, for convenience, reference will be made to a pure cigarette hard hinged packet as a non-limiting example.

  A cigarette (or cigar, cigarillo, or equivalent) packet with a rigid hinge lid consists of a cup-shaped outer box and a lid that is hinged to the outer box and moves between an open position and a closed position. Prepare. The outer box defines a compartment that houses an inner package having a group of cigarettes wrapped in aluminum foil, and is dimensioned based on the size of the inner package (ie, the cigarette group), and the outer box wall Hold the cigarettes firmly in between so that the cigarettes do not move with respect to the outer box when transporting and handling the cigarettes from the cigarette manufacturing plant to the consumer. Adjacent cigarettes do not move relative to each other. The slight movement of the cigarette inside the outer box can result in the cigarette spilling from the tip of the cigarette (on the opposite side of the filter), the cigarette being bent or possibly cracking. Therefore, it is necessary to prevent movement of cigarettes in the box.

  On the other hand, this type of cigarette packet must also be such that it can be easily extracted, especially from a full packet state (ie, when the packet is opened). This means that the cigarette must be housed fairly loosely inside the outer box, and clearly contrasts with the need to hold a group of cigarettes firmly in place as described above. It is what constitutes.

  In fact, the known cigarette rigid packet design with hinged lid is designed to hold the cigarette firmly inside the outer box to prevent movement during transport handling, and to facilitate the withdrawal of cigarettes from full packet conditions. Having a certain gap between the cigarettes has shown a trade-off between the two requirements.

In order to solve this problem, one patent document discloses that an outer box has three orthogonal main axes, each of which has a number of main walls parallel to two of the three main axes, and at least two main axes. It is defined by at least one connecting wall surface that is located between the wall surfaces and forms a predetermined angle other than zero with respect to the three main axis lines, so that the cross section of the outer box changes along each main axis line. A hard packet with a hinge lid of a cigarette has been proposed (see, for example, Patent Document 1). However, this cigarette packet is very complex to manufacture on a standard (commercial) packaging machine, but requires a specially designed machine that is much more expensive than an equivalent standard packaging machine. In addition, a certain patent document discloses a hard packet with a cigarette hinge cover having a certain trapezoidal cross section (see, for example, Patent Document 2). However, this packet does not solve the problem described above.

It is the figure which showed the hard cigarette packet group of FIG. 1 which comprises a carton. It is the figure which showed the hard cigarette packet group of FIG. 1 which comprises a carton.

  Reference numeral 1 in FIG. 1, FIG. 2 and FIG. 3 indicates an entire hard packet of cigarettes, and the packet is an outer box 2 made of hard cardboard and a group of cigarettes housed in the outer box 2. (With cross section shown in FIG. 7) and having an inner package 3 with a cigarette extraction opening on the upper front side. One group of cigarettes has a conventional three-row configuration consisting of 7/6/7 (20 in total), or other configurations (for example, a 10/10 two-row configuration or 5/5/5/5). 4 rows of books) may be arranged.

  The outer box 2 is hinged to the outer box 2 along the opening upper end 4 and the hinge 6, and an opening position (FIG. 3) for opening the opening upper end 4 with respect to the outer box 2 and a closing position for closing the opening upper end 4 (FIG. 1 and FIG. 2).

  When the lid 5 is closed, the outer box 2 has a polyhedral shape having three sets of six faces facing each other. More specifically, the outer box 2 has an upper wall 7 and a bottom wall 8 that face each other in parallel with each other, and is perpendicular to the upper wall 7 and the bottom wall 8 and extends in the longitudinal direction to form an edge of the upper wall 7. It has four side walls 9, 10, 11 connected to the corresponding edge of the bottom wall 8. These four side walls 9, 10, 11 are composed of two main (ie, large) side walls 9, 10 facing each other in parallel, and two sub (ie, small) side walls 11 facing in parallel. More specifically, one large side wall 9 forms the front wall 9 of the outer box 2, and the other large side wall 10 forms the rear wall 10 of the outer box 2. The four longitudinal end edges 12 are formed between the two small side walls 11 and the front and rear walls 9, 10, and the eight lateral end edges 13 are formed on the upper and bottom walls 7, 8. And the front and rear walls 9, 10 and the small side wall 11.

  The packet 1 has a U-shaped hard (ie, rigid cardboard) collar 14 that is glued to the inside of the outer box 2, partially extends outside the upper end 4 of the opening, and closes the lid 5. Engages with corresponding inner surface. The collar 14 has a front wall 15 that contacts the front wall 09 of the outer box 2 and two side walls 16 that are on both sides of the front wall and contact the small side wall 11 of the outer box 2. In a preferred embodiment, the collar 14 has two projections 17 that project laterally from the front wall 15 to interfere with the side walls of the lid 5 and hold the lid 5 in the closed position.

  As shown in FIGS. 4 and 5, the top wall 7 and the bottom wall 8 are trapezoidal, that is, an unequal side quadrilateral (geometrically, the unequal side quadrilateral is the “primary” base and “sub” of the quadrilateral. Defined as a quadrilateral with two parallel sides known as the base and two sides known as the hypotenuse of the quadrilateral. Specifically, the upper wall 7 has a first trapezoidal shape, and the bottom wall 8 has a second trapezoidal shape different from the first trapezoidal shape of the upper wall 7. Specifically, as shown in FIG. 4, the main base of the upper wall 7 is located on the rear wall 10 (therefore, the sub-base is located on the front wall 9), and the main base of the bottom wall 8 is shown in FIG. Is located on the front wall 9 (therefore, the minor base is located on the rear wall 10). The cross section of the outer box 2 parallel to the top wall and the bottom walls 7 and 8 continuously changes in the longitudinal direction, and the first trapezoidal shape of the top wall 7 is changed to the bottom wall (as shown in FIGS. 6 to 8). 8 to the second trapezoidal shape.

  As shown in FIGS. 1, 2, and 3, each longitudinal edge 12 has a constant shape and size along its entire length. The main side wall 9 (front wall 9) connects the sub-bottom of the top wall 7 to the main bottom of the bottom wall 8, and the main side wall 10 (rear wall 10) connects the main bottom of the top wall 7 to the sub-bottom of the bottom wall 8. Each sub-side wall 11 connects the oblique side of the upper wall 7 to the oblique side of the bottom wall 8. In the illustrated embodiment, each bottom side of the top wall 7 is parallel to each bottom side of the bottom wall 8, and the hypotenuses of the top and bottom walls 7 connected to the same sub-side wall 11 are opposite to the corresponding bottom side. It is inclined to.

  In the illustrated embodiment, the first trapezoidal shape of the top wall 7 and the second trapezoidal shape of the bottom wall 8 are isosceles trapezoids and have a regular reflection relationship.

  In this embodiment, it is a cross section (FIG. 7) of the outer box 2 parallel to the top wall and the bottom walls 7, 8, and the cross section at the longitudinal center between the top wall 7 and the bottom wall 8 is rectangular. This is an important technical feature that increases the gripping of the cigarettes, i.e. holds them in place. In a preferred embodiment, the cross section of the non-deformed (ie, undeformed) cigarette group has the same shape and the same size as the cross section at the longitudinal center of the outer box 2. This means that at the central position in the longitudinal direction, the cigarettes are not deformed at all, and only slightly deformed at any other position (the cigarettes are slightly displaced from the undeformed initial state, only a little compression occurs). This means that cigarettes have no adverse effects. In other words, the outer case of an equivalent and standard hard cigarette packet (that is, in the form of a rectangular parallelepiped) has the same cross section as the cross section of the central portion in the longitudinal direction of the outer case 2.

  In the illustrated embodiment, each sub-side wall 11 is curved spirally, i.e. spirally.

  In the illustrated embodiment, the cross section of the outer box 2 parallel to the top wall 7 and the bottom wall 8 has the same circumference at any position (ie, the outer box 2 has a constant circumference). . This is important in that the outer box 2 can be easily wrapped with a rectangular transparent plastic wrapping with excellent results in terms of appearance (i.e. without unsightly packaging folds). It is a feature.

  As shown in FIG. 9, the outer box 2 is formed from a flat and substantially rectangular blank 18, which is provided with two longitudinal fold lines 19 and a number of transverse fold lines 20, A panel 9 ′ (specifically, a front wall 9 portion forming a part of the lid 5) that forms a front wall 9 portion of the outer box 2 between the longitudinal broken line 19 and a front wall 9 of the outer box 2. Forming the rear wall 10 of the outer box 2, the panel 8 'forming the bottom wall 8 of the outer box 2, and the remaining part of the front wall 9 of the outer box 2. Panels 9 "are defined respectively.

  The panel 9 ′ is connected to a flap 21 along a horizontal fold line 20, and the flap is folded 180 ° and adhered to the inner surface of the panel 9, thereby partially reinforcing the lid 5.

  The panel 10 ′ has two wings 11 ′, which are on either side of the panel 10 ′ and separated from the panel 10 ′ by a longitudinal fold line 19, and the inner part of the two sub-side walls 11 of the outer box 2. Form. The panel 9 has two wings 11 "which are on either side of the panel 9" and are separated from the panel 9 "by a longitudinal fold line 19 to form the outer part of the two secondary side walls 11 of the outer box 2. The panel 9 ′ has two wings 11 ″ ′, which are on both sides of the panel 9 ′ and separated from the panel 9 ′ by the longitudinal fold line 19, and the two secondary side walls of the outer box 2. 11 further outer portions are formed.

  Each wing 11 ′ has two tabs 22 that are separated from the wing 11 ′ by two transverse fold lines 20 at both ends of the wing 11 and contact each inner surface of the panels 7 ′, 8 ′. Is bent at 90 °.

  In the embodiment of FIGS. 1-8, the end edges 12 and 13 are all angular. As an alternative embodiment, some of the end edges 12, 13 may be chamfered or rounded. More specifically, in the embodiment of FIGS. 11 and 12, the longitudinal edge 12 is chamfered, and in the embodiment of FIGS. 13 and 14, the longitudinal edge 12 is rounded.

  As an alternative embodiment not shown, the cigarette packet 1 comprises a rigid inner box that is inserted into the outer box 2 and can be partially separated from the outer box 2 as a slide opening type. In other words, the cigarette box 1 has a hard inner box that contains a group of cigarettes and is accommodated inside the outer box 2. It slides between a closed position in the state inserted in the outer box 2 and an open position in a state in which the inner box is partially pulled out from the outer box. In this embodiment, the outer box 2 is not provided with a lid 5, and one sub-side wall 11 replaces the opening, and either translational movement or rotation around the hinge connecting the two boxes is performed through the opening. One side causes the inner box to slide relative to the box 2. Although not necessarily so, the inner box is usually the same shape as the outer box 2 (although it is clear that it is slightly smaller than the outer box to fit inside the outer box 2).

  FIG. 15 shows a modification of the blank 18 of FIG. 9 and shows the shape of the upper tab 22 (that is, the tabs 22 on both sides of the panel 7 forming the upper wall 7 of the outer box 2). 18 is different. In the blank 18 of FIG. 15, each upper tab 22 has an isosceles trapezoidal shape with an obtuse inner angle β that coincides with the corresponding obtuse inner angle β of the panel 7 ′. In both blanks 18 of FIGS. 15 and 9, each bottom tab (that is, the one adjacent to the panel 8 ′ forming the bottom wall 8 of the outer box 2) coincides with the corresponding sharp inner angle α of the panel 8 ′. Is an isosceles trapezoidal shape having a sharp inner angle α. The inner angles α of the bottom tab 22 and the panel 8 ′ are equal, and the folded bottom tab 22 rests completely on the panel 9 ″ to create a more accurate and sturdy cigarette packet 1. Similarly, The interior angles β of the panel 7 'are equal and this also creates a more accurate and sturdy cigarette packet 1.

  FIGS. 16 and 17 show two groups of cigarette packets 1 inserted into their respective packages to form a carton of cigarette packets 1.

  The cigarette packet 1 described has many advantages.

  First of all, the cigarettes within the group are sufficiently inside the outer box 2 of the cigarette packet 1 to prevent any special cigarette movement (and thus damage) when transporting and handling the packet 1. While being held firmly, the cigarette can still be easily pulled out of the outer box 2 of the packet 1, especially when the packet is full (ie when the packet is opened). Two conflicting requirements (to prevent the movement of cigarettes during transport and handling, to easily hold the cigarettes in the outer box 2 and to easily pull the first cigarettes out of the cigarettes) An effective compromise is achieved because of the novel design of the outer box 2 such that the cross section of the outer box 2 parallel to the top wall 7 and the bottom wall 8 changes continuously in the longitudinal direction. It will be.

  Secondly, the described cigarette packet 1 can be easily manufactured even with a standard (commercial) packing machine, and the packet itself uses a blank of the outer box 2 which is only slightly different from a conventional blank. Since it can be manufactured, it is manufactured easily and inexpensively.
