Description

The present invention relates to a sliding open hard packet for tobacco products.
The present invention can be used with particular advantage in hard cigarette packets, the following description relating to this being given merely as an example.

  Sliding open rigid packets are known as types described in patent application FR-2499947-A3, patent US-4534463-A1 or US-5080227-A1. The sliding open rigid packet includes a first container, the first container contains a group of cigarettes wrapped in a sheet-like foil, and a closed position where the first container is completely inserted into the second container; A part of the first container is housed in the second container so as to slide relative to the second container between the open position where the first container is pulled out from the second container. Each container is a substantially parallelepiped and includes two end walls and side surfaces defined by side walls defined by the two end walls and separated from each other by corresponding straight longitudinal edges.

  Although marketed and generally favored by smokers due to its relative simplicity of manufacture, the above-mentioned type of sliding open hard cigarette packet lacks the non-anatomical shape and lack of safety protection of the internal cigarette. When considered, it has several drawbacks. That is, when the packet is inside the user's pocket, the inner container tends to slide open, resulting in the cigarette falling from the packet.

FR-2499947-A3 US-4534463-A1 US-5080227-A1

  The object of the present invention is to provide a rigid packet for tobacco products which is designed to overcome the above-mentioned drawbacks and which is particularly cheap and easy to manufacture.

  According to the invention, the rigid packet for tobacco products includes a first container for containing tobacco products and a second container for slidably containing the first container, the first container being completely second. The first container is configured to slide relative to the second container between a closed position to be inserted into the container and an open position in which a portion of the first container is withdrawn from the second container. Each of the container and the second container is a substantially parallelepiped, and is separated from the main side wall by upper and lower end walls, a main side wall confined by the upper and lower end walls and facing each other in parallel, and a corresponding longitudinal edge. A rigid packet for tobacco products comprising a side defined by the at least one small side wall, wherein the main side walls of the first container and the second container have the same concave surface and the same radius of curvature. And the song Radius, characterized in that it is constant along the entire length of each major side wall.

  Several non-limiting embodiments according to the present invention will now be described by way of example with reference to the accompanying drawings.

  In the accompanying drawings, reference numeral 1 denotes a container 2 for housing a cigarette group 3 wrapped in a sheet-like foil, a closed position (FIG. 1) in which the container 2 is completely inserted into the container 4, and the container 2 A container 4 for slidably containing the container 2 is included so that the container 2 slides with respect to the container 4 between an open position (FIG. 2) in which a part of the container 2 is drawn out.

  The container 4 is a substantially parallelepiped and is limited by the lower end wall 5, the upper end wall 6, the upper and lower end walls 5 and 6, and a main side wall 8 facing the substantially parallel side, and two main edges 8 from the main side wall 8. Side 7 defined by the separated small side wall 9 and the passage of the container 2 between the closed position (FIG. 1) and the open position (FIG. 2) parallel to and opposite the small side wall 9 Including an open end 11 that enables The main side wall 8 and the small side wall 9 of the container 4 are separated from the upper and lower end walls 5 and 6 by a lateral edge 12 across the length, and the lateral edge 12 is between the two main side walls 8 and the upper and lower end walls 5 and 6. The main horizontal edge 12 and the small horizontal edge 12 are divided.

  The two main side walls 8 of the container 4 are curved walls having the same concave surface and the same radius of curvature R, the radius of curvature being constant along the entire length of each main side wall 8, so that the two main side walls 8 are They are equidistant and substantially parallel along their entire length. The other walls, that is, the upper and lower end walls 5 and 6 and the small side wall 9 are flat walls.

  The container 2 is a substantially parallelepiped and is mainly defined by two main side walls 16 which are limited by the lower end wall 13, the upper end wall 14, the upper and lower end walls 13 and 14 and face each other substantially in parallel, and four longitudinal edges 18. It includes a side surface 15 defined by a parallel opposing small side wall 17 separated from the side wall 16. The main side walls 16 and 17 of the container 2 are separated from the lower end wall 13 and the upper end wall 14 by eight horizontal edges 19 across the length, and the horizontal edge 19 is located between the main side wall 16 and the upper and lower end walls 13 and 14. It is divided into four main lateral edges 19 and four small lateral edges 19 located between the small side wall 17 and the upper and lower end walls 13 and 14.

  The two main side walls 16 of the container 2 are curved walls having the same concave surface and the same radius of curvature R, the radius of curvature being constant along the entire length of each main side wall 16 and the same as the radius of curvature R of the main side wall 8. Thus, the two main sidewalls 16 are equidistant and substantially parallel along their entire length. The other walls, that is, the upper and lower end walls 13 and 14 and the small side wall 17 are flat walls.

  The top wall 14 of the container 2 includes an opening 20 that extends across the main side wall 16 and allows for extraction of a cigarette from the container 2 when the container 2 is in the open position (FIG. 2).

  The four longitudinal edges 18 of the container 2 and the two longitudinal edges 10 of the container 4 are arcuate and not angular edges, while the lateral edges 12 and 19 of the containers 2 and 4 are all angular. In other forms not shown, one or more longitudinal edges 10 of the container 4 and / or one or more longitudinal edges 18 of the container 2 may be angular. In particular, the longitudinal edge 10 of the container 4 and the longitudinal edge 18 of the container 2 may all be angular. Furthermore, in other forms not shown, some lateral edges 12 of the container 4 and / or some lateral edges 19 of the container 2 may be arcuate and non-cornered edges, and so on. The lateral edges 12 and / or 19 and the longitudinal edges 10 and / or 18 may be arcuate edges without corners.

  As will be appreciated, when the container 2 is in the closed position (FIG. 1), each side wall 8 and 9 of the container 4 aligns and faces the corresponding side wall 16 and 17 of the container 2. More specifically, both containers 2 and 4 minimize the amount of material required to manufacture containers 2 and 4, while at the same time cigarette groups 3 in container 2 and in container 4 In order to minimize the movement of the container 2, the cigarette group 3 and the container 2 are formed to have a size capable of accommodating each with a small gap. As will be apparent, the slight gap should allow the user to easily remove the cigarette from the container 2 between the cigarette group 3 and the container 2. Similarly, the slight gap should allow the user to easily pull the container 2 from the container 4 between the container 2 and the container 4.

  The dimension across the length of the main side wall 8 of the container 4 (ie parallel to the main side edge 12) is smaller than the dimension across the corresponding length of the main side wall 16 of the container 2 (ie parallel to the main side edge 12), and so on. Thus, the container 4 does not cover the two longitudinal edges 18 of the container 2 facing the open end 11 of the container 4 when the container 2 is in the closed position (FIGS. 1 and 5).

  The small side wall 9 of the container 4 includes a hole 21 (FIGS. 1 and 5) shaped and dimensioned to allow insertion of the user's finger, and the purpose of this hole is when the container 2 is in the closed position (FIG. 1). And 5), allowing the user to apply pressure on the small side wall 17 of the container 2 facing the hole 21 to allow the container 2 to escape from the container 4.

  In the packet 1 shown in FIGS. 1 to 4, the small side walls 17 are parallel, the width of the container 2, that is, the distance between the two small side walls 17 is constant, and the main side wall of the container 2 has the same dimensions. is there. 5 to 8, the small side wall 17 of the container 2 is concentrated at one point so that the width of the container 2, that is, the distance between the two small side walls 17 changes, and the main side wall of the container 2 has the same dimensions. Not. More specifically, the small side wall 17 of the container 2 is concentrated, that is, converged toward a point spaced from the center of gravity of the container 2 in the range of 80% to 120% of the radius of curvature R of the main side walls 8 and 16. Yes. Packets 1 in FIGS. 5 to 8 contain a group of 3 cigarettes formed by 20 cigarettes (not shown separately) arranged in three layers, in particular 7, 7, and 6 cigarettes. It is suitable for. As is obvious, the six cigarette layers are placed in contact with the relatively small main side wall 16 of the container 2.

  In another variant not shown, the small side wall 17 of the container 2 is branched.

  In an embodiment not shown, each main side wall 8 of the container 2 includes a recess near the open end 11, the main purpose of which is for the user to grip the main side wall 16 of the container 2 to exert a pulling force. In addition, it helps to withdraw the container 2 from the container 4 in the closed position.

  In an embodiment not shown, the packet 1 includes stop means for limiting the sliding of the container 2 with respect to the container 4 and thus preventing the container 2 from detaching from the container 4. The stopping means is formed by two first tongues protruding from the respective main side walls 16 of the container 2 and two second tongues protruding from the respective main side walls 8 of the container 4. Each first tongue projects from the respective main side wall 16 of the container 2 outwardly of the container 2, each second tongue projects from the respective main side wall 8 of the container 4 inward of the container 4, and each first The tongue portion is disposed so as to engage with the second tongue portion when the container 2 slides outward from the container 4, and prevents the container 2 from being detached from the container 4.

  By way of example, the hard cigarette packet 1 of the accompanying drawings may have a height of 8-10 cm, a width of 4.5-6 cm, a thickness of 2-3 cm, and a radius of curvature of 12-20 cm.

  Test results show that the cigarette packet 1 described above is easy to handle for the user and fits comfortably in the user's pocket due to the anatomical shape with the radii of curvature on the main sidewalls 8 and 16 It was. Furthermore, due to the curvature of the main side walls 8 and 16, the opening of the packet 1, i.e. the relative movement between the inner container 2 and the outer container 4, is not performed along a straight line, but on the curvature radius R of the main side walls 8 and 16. This is done along curves with equal radii. This condition does not cause discomfort to the user and prevents accidental opening of the packet, particularly in the user's pocket.

  In view of the advantages of the cigarette packet 1 as described above, the form of the packet 1 can be integrally applied to the manufacture of a rigid container for cigarette packets or other types of cigarette products such as cigar packet cartons.
