Description

box and lid

technical field

The invention relates to a box according to the preamble of claim 1 and a cover for such a box.

Background of the invention

Box form packages for snuff, loose snuff and packaging bulk commodities usually consist of boxes which are discarded when the contents are used up. The box comprises a lower part, a pot provided with an upper part, a lid that allows the box to be opened and reclosed a number of times, usually about 20 to 50 times. Such a box advantageously consists of plastic material. In order to save space, material and cost, the material of the box should be as thin as possible.

A known box of this type is shown in SE524025, and has a basic shape comprising a right cylinder of low height, and generally resembles a disc. Starting from this basic shape, a box can have rounded edges, a curved lid, and a profiled bottom, for example. There will usually be a lip or similar shape along the periphery of the vessel for the lid to rest on when the box is closed. This rim can be made such that the diameter of the wall of the vessel is slightly smaller above the rim than below the rim.

One problem with known boxes is that the lid often exhibits a tendency to stand askew on the vessel. This problem is often more intractable and occurs more frequently where the material thickness of the vessel and lid is reduced. A lid mounted askew means that the lid will fall off immediately or the box will not be closed properly. If, again, it is not closed properly, the contents of the box will come out of the box or it may dry out or become contaminated, or the quality may be compromised in some other way.

Contents of the invention

An object of the present invention is to produce an improved box which completely or partly eliminates the problems inherent in the prior art.

This object is achieved in whole or in part by a box and a lid, respectively, according to each independent claim.

Embodiments of the invention are set out in the dependent claims, the ensuing description and the figures.

According to a first aspect of the invention, a box is manufactured comprising an open container and a lid for closing the open container. In the closed state, the box is bounded by two base surfaces and at least one side surface, wherein one of the two base surfaces consists of the bottom wall of the open container, and the two Another of the base surfaces consists of the top wall of the lid, and the at least one side surface is formed by the sides of the container and the sides of the lid. In the closed state of the box, the container side and the lid side at least partially overlap each other. A distinctive feature of the lid is that an inwardly facing, inclined slide surface is provided on the inside of the top wall of the lid to allow the lid to move into the correct closed position relative to the container when closing the open container. The sliding surface extends at an angle relative to the top wall and the lid side along and adjacent to and away from the lid side.

When closing an open container, a box having the aforementioned features allows an incorrectly placed lid to be easily moved to the correct closed position relative to the open container. This can be used to aid in correct fitting of the cover and reduce the risk of incorrectly fitting the cover.

According to one embodiment, the inclined sliding surface can be formed such that the material thickness of the portion of the top wall adjacent to the sides of the lid is greater than the material thickness of the portion closer to the center of the top wall.

This cover design creates an inclined sliding surface which facilitates correct installation of the cover and reduces the risk of incorrectly installing the cover.

According to one embodiment, a groove may be provided on the inner side of the top wall of the lid, adjacent to the side of the lid, said groove being delimited by a low flange, the sliding surface being arranged on the inner side of the flange.

This cover design facilitates correct installation of the cover and reduces the risk of incorrectly installing the cover.

According to one embodiment, positively interlocking means may be provided for securing the lid relative to the open container when the box is in the closed state.

Such a device produces a secure closure of the container.

According to one embodiment, at least one dimension in the base surface may be greater than the height of the box in the closed state.

This design makes it possible to produce a box suitable for packaging snus, for example, which is relatively flat and thus easy to handle and store.

According to a second aspect of the invention, a box lid is produced for closing an open container. In the closed state, the box is bounded by two base surfaces and at least one side surface, wherein one of the base surfaces is formed by the bottom wall of the open container and the other of the base surfaces is formed by the lid The at least one side surface is formed by the side of the container and the side of the lid. In the closed state of the box, the container side and the lid side at least partially overlap each other. A notable feature of the box is that an inwardly facing, inclined sliding surface is provided on the inside of the lid top wall to allow the lid to move into the correct closed position relative to the container when the open container is closed. The sliding surface extends at an angle relative to the top wall and the lid side along and adjacent to and away from the lid side.

When closing an open container, a lid having the aforementioned features allows an incorrectly placed lid to be easily moved into the correct closed position relative to the open container. This can be used to facilitate correct fitting of the cover and reduce the risk of incorrectly fitting the cover.

According to one embodiment, the inclined sliding surface can be formed such that the material thickness of the portion of the top wall adjacent to the sides of the lid is greater than the material thickness of the portion closer to the center of the top wall.

According to one embodiment, a groove may be provided on the inside of the top wall of the lid, adjacent to the side of the lid, said groove being delimited by a low flange, the sliding surface being arranged on the inside of the flange.

specific implementation plan

1 to 5 show an embodiment of a box 1 comprising an open container 2 and a lid 3 for closing the open container 2 . The lid 3 is not bound by the open container 2, that is to say the two parts are not coupled together or connected by a hinge or any other similar means. In the basic form shown in Figure 1, the box 1 fitted with the lid 3 consists of a substantially straight cylinder whose inner space is delimited by two base surfaces 4, 5 and one side surface, wherein said base surface One of 4, 5 consists of the bottom wall 4 of the open container and the other of said base surfaces 4, 5 consists of the top wall 5 of the lid 3, said side surface being the circumferential surface of the cylinder. The side surfaces are formed by the side 6 of the container, called the side 6 of the container, and the side 7 of the lid, which side 6 is called the side 7 of the lid. Other shapes of boxes that may appear suitable to a person skilled in the art may also be used, for example a box 1 in the form of a cylinder with non-circular base surfaces 4, 5, with or without rounded edges or corners regular hexahedron or rectangular block. Figures 6a to 6e show examples of embodiments of the shape of the base surfaces 4, 5 viewed from above. It should be understood that, for example, if the box 1 has the shape of a regular hexahedron or rectangular block, then the interior space of the box 1 will be delimited by said base surfaces 4, 5 and four side surfaces, both the container side 6 and the lid side 7 comprising four sides. a side part. In various embodiments, the bottom wall 4 and top wall 5 may be flat or arched or may have some other cross-sectional shape when viewed from the side, which may be dictated by functional or cosmetic considerations . Figures 7a to 7c show examples of the described embodiment of the shape of the box 1 viewed from the side. In one embodiment, each of the bottom wall 4 and the top wall 5 is arched inwardly and outwardly relative to the box 1 with the same radius of curvature, as shown in FIGS. 4 and 5 .

As mentioned above and shown in Figure 2, the open container 2 is bounded by a bottom wall 4 and a peripheral container side 6. In the embodiment shown in Figure 2, the open container 2 has a substantially circular transverse shape when viewed from above. section. It must be pointed out again that the box 1 may have other embodiments as mentioned above, the open container 2 also taking a corresponding shape, for example a regular hexahedron or a rectangular block. 2, 4 and 5, the peripheral container side 6 of the open container 2 may likewise, like its exterior, comprise a straight portion 8 positioned adjacent to and perpendicular to the bottom wall 4 , and the outside of the straight portion 8 constitutes the peripheral surface of a right cylinder. Arranged on the outside, adjacent to the straight portion 8 , is an inwardly and upwardly directed edge 9 , the edge 9 closest to the straight portion 8 may also comprise a narrow edge at right angles to the straight portion 8 . Arranged directly above the edge 9 is an obliquely inwardly directed flange 10 , and an upper side 11 of the flange extends obliquely inwards and upwards from the outer circumference of the flange 10 . An outer side portion 12 is located above the flange 10, the side portion 12 having the same shape as the straight portion 8 but having a somewhat smaller diameter. The inner side of the circumferential container side 6 is flat without any functional parts.

As mentioned above and shown in Figures 3 to 5, the lid adjacent to the top wall 5 of the lid 3 is bounded by a peripheral lid side 7 which, in the embodiment shown in Figures 3 to 5, has a A substantially circular cross-section when viewed, and when the box 1 is closed, the circumferential lid side 7 is substantially concentric with and outside the container side 6 of the open container. At the bottom on the inner side of the peripheral lid side, the peripheral lid side 7 may also include means 13 designed to positively interlock with corresponding means 10 on the container side 6 so that when the box 1 is in the closed The container 2 secures a lid 3 . Such means 10 , 13 may consist, for example, of snap fastener elements 10 , 13 . Such snap elements 10 , 13 are shown in FIG. 5 and consist in this embodiment of flanges 13 which, when the box 1 is closed, fit into the corresponding flanges 10 of the container side 6 described above. Engaged, the flanges 10, 13 can rest on each other. Furthermore, a plurality of ridges 14 for guiding the lid relative to the container side 6 may be provided around the inside of the lid side 7 . The ridge 14 shown in FIG. 3 extends substantially from the transition between the top wall 5 of the lid 3 and the lid side 7 down the inside of the lid side 7 to about half the height of the lid side 7 . These ridges 14 rest on the outer side portion 12 of the side 6 of the container when the box 1 is closed.

According to one embodiment, a groove 15 is provided on the inside of the top wall 5 of the lid 3 , adjacent to the peripheral lid side 7 , said groove 15 being delimited by a flange 16 having a relatively low height. The groove 15 is wider than the upper edge 17 of the container side 6 of the open container and the upper edge 17 rests against, or closes to, the bottom of the groove 15 when the box 1 is closed. In one embodiment, the upper edge 17 rests against the bottom of the groove 15 and determines how much the container side 6 and the lid side 7 overlap each other. Furthermore, the upper edge 17 may have a suitable diameter so that when closed it rests against the inner side of the lid side 7 and the outermost part of the lower side of the flange 13 which is directed obliquely outwards and downwards. This design is easy to close. When closing, the upper edge 17 is pressed against the lid side 7 so that the lid side is depressed springing outwards substantially at a right angle, which facilitates especially the first stage of fitting the lid 1 . Portion 18 has a thickened cross-section when viewed from the side, which portion 18 may be located inwards from flange 16 towards the center of the lid. The material thickness of this portion 18 decreases inwards towards the center and determines a short distance into the top wall 5 of the lid 3 . A surface 19 is thus formed on the inside of the lid along which the upper edge 17 of the outer side portion 12 of the container can slide if the lid 3 is erected askew on the open container 2 . It has now surprisingly been found that the embodiment with the sliding surface 19 in the lid 3 eliminates or at least greatly reduces the above-described problems caused by the lid 3 being placed askew on the open container 2 . The crookedly placed lid 3 is easily moved, the upper edge 17 of the container side 6 sliding on the inclined surface 19 , past the flange 16 and down into the groove 15 . Additionally, the cover side 7 can

As shown in FIG. 8 , the top wall 5 can also be designed with a space, which is located on the side of the top wall 5 away from the inner side of the box 1 and is bounded by the top wall 5 and the outer cover 20 . This can be used to create a smaller enclosed space that can be used, for example, for temporary storage of used snus portions. One embodiment of a cover comprising such a space is described in WO 2005016036.

As shown in Figure 9, one embodiment of the box 1 may comprise a bottom wall 2 designed with a raised portion 21 forming a channel 22 around the raised portion and inside the sides of the container. Such protruding parts are described in SE 524025.

Various changes to the design may be made in addition to the changes described here without departing from the scope of the inventive concept. Furthermore, apart from different implementations of individual details, such as the snap elements 10, 13 and the guide ridges 14, it is also possible, when the box 1 is closed, that the lid side 7 is located inside the container side 6, the functional parts of the lid 3 and the container 2 reversed so that the sliding surface 19 in this case is part of the container 2. In this case, function and design would otherwise remain the same. These and other embodiments of the invention will be apparent to those skilled in the art.
