Description

Container with improved magnetic lock

The present invention relates to a container for consumer products and a blank for forming such a container, which finds particular application for retaining elongated consumer goods (e.g. cigarettes) such as smoking articles.

The smoking article is typically packaged in a rigid hinged lid container formed of foldable laminate blanks. By way of example, elongated smoking articles such as cigarettes and cigars are often sold as boxes of rigid boxes, such as hinged lid containers having a box portion and a lead connected to the box around a hinge line extending across the rear wall of the container. do. In use, the leads are pivoted about the hinge line to open the pack, thereby approaching the consumer item held in the box. In fact, in order to access the smoking article or other consumer goods, the consumer typically grabs the box portion with one hand, uses the other hand to pivot the lid portion around the hinge line, and removes the smoking article from the box portion.

Such a pack typically consists of a one-piece laminated cardboard blank. In some cases, the container further comprises a reinforced inner frame at least partially wrapped around the consumer article. This can provide additional rigidity to the container and protect the consumer item. Additionally, the inner frame extending beyond the upper edge of the box front wall makes it easier for the lead front wall to align with the box front wall when the lid is in the closed position, so that the container has a substantially flat front surface to the consumer to provide.

The hinged lid can often experience problems such as box portions and leads that are not exactly aligned due to twisting of the leads, so that the gap is visible on the front of the container between the lead and the box portion. This is often referred to as the "smiling" effect. The degree to which smiling occurs typically increases with the extended use of the package.

This is often handled by frictionally engaging the lead with the surface of the inner frame. However, this type of mechanism may become unreliable after repeated opening and closing of the container, since the inner frame surface that engages the leads may also experience torsion or wear.

As an alternative, application of the magnetic composition on the front surface of the inner frame and on the inner surface of the lead has been proposed in WO 2014/096427. This provides a hinged lid container with a magnetic locking device that is capable of reliably maintaining the lid in the closed position even after repeated opening and closing of the container. In particular, WO 2014/096427 discloses the use of magnetic compositions (e. G. Magnetic inks) for gravure printing, offset printing, flexographic printing, lithographic printing, Screen printing, slot die coating, roll coating or reverse roll coating, knife-over-roll gravure, and reverse direct gravure for example by techniques such as gravure, wire rod coating, air-knife coating, or slot-orifice coating.

However, in order to ensure sufficient magnetic force, a considerable amount of magnetic composition should be used. To achieve this, the magnetic composition needs to be applied to a multi-pass process to form a superposed layer, so that a coating of sufficient thickness is formed.

It would therefore be desirable to provide a container with improved means for maintaining the container in a closed condition. In addition, it would be desirable to provide such a container that can be assembled and packed using conventional high-speed methods without requiring any major deformation of existing packing devices. Moreover, it would be desirable to provide a method of forming such an improved consumer container.

According to an aspect of the present invention, there is provided a container for a consumer article. The container is a box portion at least partially formed from a blank having a thickness T, the blank defining a front wall of the box portion; A lead portion suspended from the rear wall of the box portion along the hinge line, the lead portion being movable about an hinge line between an open position where the consumer material can be removed from the container and a closed position where the consumable material can not be removed from the container, Lead portion; And an inner frame received within the box portion, wherein the inner frame includes an inner frame front wall and the portion of the frame front wall extends beyond the upper edge of the front wall of the box portion. In addition, the container includes a magnetic locking device comprising a first magnetic material provided on the inner surface of the lead portion and a second magnetic material provided on the inner frame front wall, wherein the first and second magnetic materials comprise a lead portion Are arranged to overlap when in the closed position, so that the magnetic locking device releasably retains the lid portion in the closed position. The second magnetic material is a flexible magnetic laminate material applied on the outer surface of the inner frame front wall such that the outer surface of the flexible magnetic laminate material is located on the front wall of the box portion by a distance substantially corresponding to the thickness T of the blank And is horizontally offset from the outer surface.

Figure 2 shows a schematic cross-sectional view of the container of Figure 1;
Figure 3 shows a schematic plan view of a strip of continuous blank material from which an inner frame for a container according to the invention can be cut;
Figure 4 shows a schematic plan view of a blank for forming a box and lid portion of a container in accordance with the present invention.

According to a further aspect of the present invention, a method of forming a container for a consumer material is provided. The method includes: providing first and second laminated blanks, wherein the first laminated blank has a thickness (T); Applying a first magnetic material on the first laminated blank; Applying a second magnetic laminate material on a second laminate blank; And folding the first and second laminated blanks to form first and second foldable blanks, wherein the foldable blank cooperates to form a container including a compartment for accommodating consumer items do. The method further includes inserting a second foldable blank in the first foldable blank so that at least a portion of the first foldable blank has a closed position in which the consumer can not be removed from the compartment and a closed position where the consumer can be removed from the compartment And is movable relative to the second foldable blank between the open positions. Wherein the first magnetic material and the flexible magnetic laminate material are arranged to overlap with each other when the movable portion is in the closed position so that the first magnetic material and the flexible magnetic laminate The material forms a magnetic lock that holds the moveable portion releasably in the closed position. Moreover, the second magnetic material is a flexible magnetic laminate material applied on the second laminate blank before the second laminate blank is folded and received in the first foldable blank, so that in the assembled container the outer surface of the flexible magnetic laminate material Is offset from the outer surface of the first foldable blank by a distance substantially corresponding to the thickness (T) of the blank.

It is to be understood that any feature described with reference to one aspect of the present invention may be equally applied to any other aspect of the present invention.

In contrast to a known container, in a hinged lid according to the invention, a magnetic locking device is provided by combining the magnetic material applied on the surface of the lid with a flexible magnetic laminate material applied on the outer surface of the inner frame front wall. More specifically, a portion of the flexible magnetic laminate material is included between the inner surface of the box front wall and the outer surface of the inner frame front wall. That is, the flexible magnetic laminate material is applied on the outer surface of the inner frame front wall such that the outer surface of the flexible magnetic laminate material is spaced from the outer surface of the front wall of the box portion by a distance substantially corresponding to the thickness T of the blank As shown in FIG. From a manufacturing standpoint, this means that the flexible magnetic laminate material is applied onto the blank before the inner frame blank is folded and inserted into the box portion of the container. Thus, in the assembled container, at least a portion of the magnetic laminate material is contained between the outer surface of the inner frame front wall and the inner surface of the box front wall.

According to the present invention, it is easy to form a container with a magnetic locking device that provides a reliable means for maintaining the lid in the closed position, even after repeated opening and closing of the container. In addition, the magnetic material can be applied without modifying the existing blank to a minimum or without any modification, so that the existing device can be conveniently used to form the container according to the present invention.

In particular, combining a layer of magnetic material, such as a layer applied by printing with a magnetic ink, with a flexible magnetic laminate material, such as a flexible magnetic tape, provides sufficient magnetic force to maintain the lid reliably in the closed position.

In addition, since the magnetic surface defined by the outer surface of the flexible magnetic laminate material is offset relative to the outer surface of the box front wall by a distance substantially equal to the thickness of the blank portion forming the box front wall, , The front wall of the lid can be easily aligned with the box front wall while completely covering the magnetic material. This contributes to minimizing the visual impact of the first and second magnetic materials provided on the container. At the same time, the container provides the user with a substantially flat front surface, and the ingress of dust or other small particles into the container is advantageously prevented.

As used herein, the terms "forward", "rear", "upper", "lower", "upper", "lower", "horizontal", "horizontally", " And "side" refer to the relative position of a portion of a container and its components in accordance with the present invention when the container is in an upright position with a hinge line at the rear of the container with a lead of the outer housing at the closed position. When describing a container according to the present invention, these terms are used regardless of the orientation of the container being described. The rear wall of the container is a wall containing a hinge line.

The term "inner surface" is used throughout this specification to refer to the interior side of the container, for example the side of a portion of the blank facing toward the consumer, once the container is in the closed position. The term "outer surface" is used throughout the specification to refer to the side of a portion of the blank facing the exterior of the container when the container is assembled.

The term "magnetic material" is used throughout this specification to describe a material capable of interacting with a magnetic field, including both paramagnetic and ferromagnetic materials. Since the magnetisable material is a paramagnetic material, it can only remain magnetized in the presence of an external magnetic field. Alternatively, the magnetizable material may be a material that is magnetized in the presence of an external magnetic field and remains magnetized after the external magnetic field is removed (e.g., a ferromagnetic material). As used herein, the term "magnetic material" encompasses both magnetizable materials as well as the types of materials already magnetized.
