Description

  The present invention relates to a box relating to the first half of claim 1 and a lid of the box.

    Snuff tobacco box-like packaging, whether from bulk snuff or packed goods, is most commonly composed of boxes that are discarded when their contents are consumed. The box is composed of a lower container with an upper lid, the box can be opened and closed many times, often 20 to 50 times. Such a box is advantageously constructed of a plastic material. The box should be as thin as possible to save space, material, and price.

A well-known box of this kind is shown in SE 524025, whose basic shape is a low, straight cylinder, often associated with a pack. Proceeding from this basic shape, the box may have, for example, a rounded edge, a curved lid, and a rectangularly shaped lower part. Along the outer periphery of the container, it often has an edge or the like because the lid is supported when the box is closed. This edge is formed where the container wall has a somewhat smaller radius at the top than at the bottom of the edge.

  One problem with known boxes is that the lid often tends to tilt over the container. This problem is more troublesome and occurs more frequently where the container and lid thickness is reduced. An obliquely fitted lid means that the lid falls off immediately or that the box is not closed properly. If it does not close properly again, the contents of the box may fall out of the box, or it may dry out or become contaminated. There may also be some degradation in quality by other methods.

  The object of the present invention is to produce an improved box that completely or partially eliminates the problems inherent in the prior art.

  The problem is solved completely or partially by a box and lid according to each independent claim.

  Embodiments of the invention are described in the dependent claims together with the following description and the accompanying drawings.

According to the first aspect of the present invention, the box is made up of an open container and a lid for closing the open container. In the closed state, the box is formed by two base surfaces: a base surface composed of the bottom wall of the open container and a base surface composed of the top wall of the lid, and the container side surface and the lid side surface. And at least one aspect. In the closed box, the container side and the lid side at least partially overlap each other. The distinguishing feature of the lid is that an inwardly facing and inclined sliding surface is placed inside the top wall of the lid to move to the correct lid closing position relative to the container when the box is closed. . The slide surface is provided at an angle with respect to the upper wall and the lid side surface along and adjacent to the lid side surface, and is separated from the lid side surface. The inner side of the lid side surface includes a plurality of protrusions extending downward along the inner side of the lid side surface from the transition between the upper wall of the lid and the side surface of the lid.

  When closing the open container, the box with the aforementioned characteristics allows the lid in the wrong position to be easily moved to the correct closed position with respect to the open container. This serves to encourage correct installation of the lid and reduces the risk of incorrectly installing the lid.

  According to one embodiment, the inclined slide surface is formed where the upper wall has a thicker material thickness in a portion where the upper wall is adjacent to the lid side surface than a portion closer to the center of the upper wall.

  Such a lid design provides an inclined sliding surface that facilitates correct lid attachment and reduces the risk of inaccurate lid attachment.

  According to one embodiment, a groove defined by a low flange, on which the sliding surface is arranged, may be arranged inside the top wall of the lid adjacent to the lid side.

  Such a lid design facilitates the correct installation of the lid and reduces the risk of incorrect installation of the lid.

  According to one embodiment, means for securely connecting are provided for securing the lid to the open container with the box closed.

  Such a method achieves a positive closure of the container.

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

  Such a design provides a box suitable for snuff packaging, such as a box that is relatively flat and thus easy to handle and store.

  According to claim 2 of the present invention, the box lid is manufactured to close the open container. In the closed state, the box is formed by two base surfaces, a base surface composed of the bottom wall of the open container, a base surface composed of the top wall of the lid, and the container side surface and the lid side surface. Defined by at least one aspect. In the closed box, the container side surface and the lid side surface at least partially overlap each other. The distinguishing feature of the box is that an inwardly facing and inclined sliding surface is placed inside the top wall of the lid to move the lid to the correct closed position relative to the container when closing the open container. It is. The slide surface is provided at an angle with respect to the upper wall and the lid side surface along and adjacent to the lid side surface, and is separated from the lid side surface.

  When closing the open container, the lid having the above-mentioned characteristics can easily move the lid in the incorrect position to the correct closed position with respect to the open container. This serves to facilitate correct installation of the lid and also reduces the risk that the lid will be installed incorrectly.

  According to one embodiment, the inclined slide surface is formed where the upper wall has a thicker thickness in a portion adjacent to the lid side surface than in a portion closer to the center of the upper wall.

  According to one embodiment, a groove defined by a low flange on which the slide surface is located may be located inside the top wall of the lid adjacent to the lid side.

  A more detailed description of the embodiments is given below with reference to the accompanying drawings.

  1 to 5 show an embodiment of a box 1 composed of an open container 2 and a lid 3 for closing the open container 2. The lid 3 is free from the open container 2, i.e. the two parts are not connected or connected by hinges or other similar arrangements. In the basic shape shown in FIG. 1, a box 1 to which a lid 3 is attached is basically composed of a straight circular cylinder, and its internal space has an opening container together with the side surface, that is, the circumferential surface of the cylinder. The base surface 4 is composed of the bottom wall 4 and the base surface 5 is composed of the base surface 5 composed of the top wall 5 of the lid 3. The side surface is formed by a side surface 6 of the container called the container side surface 6 and a side surface 7 of the lid called the lid side surface 7. Other box 1 shapes that appear to be suitable for those skilled in the art are, for example, the shape of a cylinder with non-circular base surfaces 4, 5, a cube with or without curved edges or corners, or a cuboid A box 1 such as may also be used. 6a-e show top views of one embodiment of the shape of the base surfaces 4,5. If the box 1 has, for example, a cubic or rectangular block shape, the inner space of the box 1 is defined by the base surfaces 4, 5 and four side surfaces, both the container side surface 6 and the lid side surface 7. Will be understood to consist of four aspects. In various embodiments, the bottom wall 4 and the top wall 5 may have a flat or arched shape, or other cross-sectional shape as seen from the side, as determined by function and appearance considerations. Figures 7a-c show an example of said embodiment in the shape of box 1 as viewed from the side. In one embodiment, the bottom wall 4 and the top wall 5 are externally arched with the same radius of curvature, respectively on the inside and outside of the box 1, as seen from FIGS. 4 and 5, respectively. ing.

  As mentioned above and as shown in FIG. 2, the open container 2 has a bottom wall 4 and, in the embodiment shown in FIG. 2, a circumference having a basically circular cross section when viewed from above. The container side 6 is defined. It has to be pointed out again that the box 1 may have other embodiments as described above. Instead, the open container 2 has a corresponding shape such as a solid or rectangular block shape. With reference to FIGS. 2, 4, and 5, the circumferential container side 6 of the open container 2 may instead be composed of a straight portion 8, such as on its outer side, adjacent to the bottom wall 4. In position, perpendicular to its plane, its outer side is composed of the circumferential surface of a straight circular cylinder. Arranged on the outside adjacent to this is an edge 9 directed inward and upward, which is closest to the straight part 8 and may be composed of a thin edge perpendicular to the straight part. The flange 10 is arranged immediately above the edge 9 and faces diagonally inward, and from the outer periphery of the flange 10, the upper side 11 of the flange extends diagonally inward and upward. The outer side surface portion 12 is located on the flange 10, and the side surface portion 12 has the same shape as the straight portion 8, but has a somewhat smaller radius. The inside of the circumferential container side surface 6 is a plane if there is no functional part.

  As described above and as shown in FIGS. 3-5, the lid adjacent to the top wall 5 of the lid 3 is defined by a circumferential lid side surface 7, which in the embodiment shown in FIGS. When viewed from the top, it has a basically circular cross section, and when the box 1 is closed, it is essentially concentric with the container side 6 of the open container and located outside it. At its inner bottom, the circumferential lid side surface 7 may alternatively consist of means 13, which in order to fix the lid 3 to the open container 2 with the box 1 closed, Designed to securely connect with corresponding means 10 on 6. Such means 10, 13 may be composed of fasteners 10, 13, for example. Such fasteners 10 and 13 are shown in FIG. 5 and, in this embodiment, are composed of flanges 13 and, as described above, when the box 1 is closed, Adapted to engage, the flanges 10, 13 are able to support each other. Furthermore, many protrusions 14 for guiding the lid to the container side surface 6 may be provided around the inside of the lid side surface 7. The protrusion 14 shown in FIG. 3 extends from the transition between the upper wall 5 of the lid 3 and the lower lid side surface 7 along the inside of the lid side surface 7 to a height approximately half of the lid side surface 7. When the box 1 is closed, these protrusions 14 come into contact with and support the outer side surface portion 12 of the container side surface 6.

According to one embodiment, the groove 15 is arranged inside the top wall 5 of the lid 3 adjacent to the circumferential lid side surface 7, the groove 15 being defined 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 when the box 1 is closed, the upper edge 17 is placed in contact with or near the bottom of the groove 15. . In one embodiment, the top edge 17 is placed in contact with the bottom of the groove 15 and determines how far the container side 6 and the lid side 7 overlap each other. The upper edge 17 further has a radius adapted to contact and support the inside of the lid side 7 and the outermost part of the lower part of the flange 13 facing obliquely outward and downward when closing it. . Such a design makes it easy to close. The top edge 17 is pressed against the lid side surface 7 so that the lid side surface is essentially right-angled and elastically pressed outwards when closed, a first stage that fits the lid 1. Is noticeable. A portion 18 having a thickened cross section when viewed from the side may be disposed inward from the flange 16 toward the center of the lid. The material thickness of the portion 18 becomes thinner toward the center and reaches the upper wall 5 of the lid 3 at a short distance. The surface 19 is thus formed on the inside of the lid, and if the lid 3 ends obliquely on the open container 2, the upper edge 17 of the outer surface 12 of the container can slide along that surface. it can. It is surprisingly clear that this embodiment with the sliding surface 19 of the lid 3 eliminates or at least significantly reduces the above-mentioned problems caused by the lid 3 placed obliquely on the open container 2. is there. The lid 3 placed at an angle is simply moved, the upper edge 17 of the container side 6 sliding on the inclined surface 19 falls over the flange 16 and into the groove 15. Furthermore, the lid side surface 7
As shown in FIG. 8, the upper wall 5 may be designed to be located on the side away from the inside of the box 1 and to have a space defined by the upper wall 5 and the outer lid 20. This serves to create a small sealed space that may be used, for example, for temporary storage of used snuff. An example of a lid made up of such a space is described in WO2005016036.

  As shown in FIG. 9, one embodiment of the box 1 may consist of a bottom wall 2 designed with a protrusion 21, so that a channel 22 is provided around the protrusion and inside the container side. Form. Such a protrusion is described in SE 524025.

  Without departing from the spirit of the invention, the design may be varied in various ways added to what has been described herein. Apart from the different embodiments of the individual details, such as the fasteners 10, 13 and the guide projections 14, in this case for the lid side 7 to be located inside the container side 6 when the box 1 is closed, It is also possible for the functional parts of the lid 3 and the container 2 to be reversed such that the slide surface 19 is part of the container 2. In such cases, the function and design remain the same in other respects. These and other embodiments of the invention will be apparent to those skilled in the art.
