Description

The present invention relates to a box described in the introductory part of claim 1, and to a lid for such a box.

Background of the invention

Packaging in the form of boxes for snuff powders, both in bulk and in the form of packaged portions of the goods, is usually a box that is thrown away after consuming the contents. A box consists of a lower part, a container for which an upper part is provided, a lid that allows you to open and close the box a certain number of times, often around 20-50 times. Such boxes are mainly made of polymeric material. In order to save volume and material and reduce costs, the material of the box should be as thin as possible.

A known box of the specified type is described in patent 8E 524025; The basic shape of the box is a low straight round cylinder and often resembles a washer. A box made on the basis of the said basic shape may have, for example, rounded edges, a curved lid and a profiled bottom. An edge is often provided on the outer circumference of the container, against which the lid should rest when the box is closed. This edge can be obtained due to the fact that the wall of the container above the edge has a slightly smaller diameter than under the edge.

One of the problems associated with known types of boxes is that the lid often has a tendency to skew the container. This problem is often complicated and occurs more often in the case of a decrease in the thickness of the material of the container and the lid. A distortion of the lid may cause the lid to immediately pop off or the box to be closed incorrectly. If the box is closed incorrectly, the contents of the box may fall out of the box, may dry out or become dirty, or the quality of the contents may otherwise deteriorate.

Brief description of the invention

The aim of the present invention is to create an improved box that would completely or partially eliminate the problems inherent in the prototype.

This goal is fully or partially achieved due to the box and the lid in accordance with the relevant independent claims.

Embodiments of the invention are described in the independent claims, in the description below and in the drawings.

According to a first aspect of the present invention, there is provided a box consisting of a container and a lid for closing the open container. In the closed state, the shape of the box is determined by two main surfaces, one of which forms the bottom wall of the container, and the second the top wall of the lid, and at least one side surface that forms the side of the tank and the side of the lid. When the box is closed, the side of the container and the side of the lid are at least partially overlapping. A distinctive feature of this lid is that the inner side of the upper wall of the lid has an inwardly inclined sliding surface located in such a way that when the open container is closed, the lid can be moved relative to the container to the correct position for closing. This sliding surface runs along the side of the lid at an angle to the top wall and to the side of the lid and does not adjoin the side of the lid.

When an open container is closed, the box having the above features makes it possible to easily move the incorrectly installed cover relative to the open container to the correct position for closing. This contributes to the correct installation of the cover and reduces the chance that the cover will be installed incorrectly.

In accordance with one embodiment of the invention, said inclined sliding surface can be formed due to the fact that the upper wall in the area adjacent to the side of the cover has a greater thickness than in the area closer to the center of the upper wall.

This design of the cover forms an inclined sliding surface, which contributes to the correct installation of the cover and reduces the likelihood that the cover will be installed incorrectly.

In accordance with one embodiment of the invention, a groove adjacent to the side of the cover and formed by a low protrusion may be provided on the inside of the top wall of the lid, and a sliding surface is formed inside the groove.

This design of the cover contributes to the correct installation of the cover and reduces the likelihood that the cover will be installed incorrectly.

In accordance with one embodiments of the invention for fixing the cover with respect to the open container, when the box is in the closed state, devices of mutual coupling can be used.

Such devices provide reliable closure of the container.

In accordance with one embodiment of the invention, at least one of the dimensions of the main surfaces may be greater than the height of the box when closed.

- 1 010237

This design allows you to create a box suitable for packing snuff powders, for example, a relatively flat box, which, accordingly, simplifies handling and storage of the box.

According to a second aspect of the present invention, a box lid is provided for closing an open container. In the closed state, the shape of the box is determined by two main surfaces, one of which forms the bottom wall of the container, and the second the top wall of the lid, and at least one side surface that forms the side of the tank and the side of the lid. When the box is closed, the side of the container and the side of the lid are at least partially overlapping. A distinctive feature of this lid is that the inner side of the upper wall of the lid has an inwardly inclined sliding surface located in such a way that when the open container is closed, the lid can be moved relative to the container to the correct position for closing. This sliding surface extends along the side of the lid at an angle to the top wall of the lid and to the side of the lid and does not adjoin the side of the lid.

When closing an open container, a lid having the above features makes it possible to easily move an improperly installed lid relative to the open container to the correct position for closure. This contributes to the correct installation of the cover and reduces the chance that the cover will be installed incorrectly.

In accordance with one embodiment of the invention, said inclined sliding surface may be formed due to the fact that the upper wall in the area adjacent to the side of the cover has a greater thickness than in the area located closer to the center of the upper wall.

In accordance with one embodiment of the invention, a groove adjacent to the side of the cover may be provided on the inside of the top wall of the cover; This groove is formed by a low protrusion, and a sliding surface is provided inside the groove.

Below is a more detailed description of embodiments of the invention with reference to the accompanying drawings.

Description of embodiments of the invention

FIG. 1-5 shows a variant of box 1 consisting of a container 2 and a lid 3 for closing the container 2. The lid 3 is not connected to the container 2, that is, these two parts are not interconnected, do not have a hinge joint or other similar connections. In the basic form shown in FIG. 1, the box 1 with the lid installed 3 is basically a straight cylinder of circular cross section, the inner space of which is defined by two main surfaces 4, 5, one of which is the bottom wall 4 of the container 2, and the second is the top wall 5 of the cover 3, and also a side surface, i.e. a side surface of said cylinder. This side surface forms the side part 6 of the indicated container, hereinafter referred to as the side part 6 of the container, and the side part 7 of the lid, hereinafter referred to as the side part 7 of the lid (reference symbols 6 and 7 on the drawings are shown conventionally). Other forms of box 1 may also be used that may seem appropriate to a person skilled in the art, for example, a cylinder-shaped box 1 with main surfaces 4, 5 that have a different shape than a round one, in the shape of a cube or a rectangular parallelepiped with rounded edges or corners or without rounding. FIG. 6a-e illustrate examples of variations in the shape of the main surfaces 4, 5 in a plan view. It is taken into account that if box 1 has, for example, the shape of a cube or a rectangular parallelepiped, the inner space of box 1 is defined by the indicated main surfaces 4, 5 and four side surfaces; however, both the side part 6 of the container and the side part 7 of the lid consist of four side sections. In various embodiments of the invention, the bottom wall 4 and the top wall 5 may be flat or curved or may have some other cross-sectional shape in the side view, which may be dictated by the purpose of the box or considerations related to the appearance of the box. FIG. 7a-c depict examples of these options for the shape of boxes 1 in side view. In one embodiment, the bottom wall 4 and the top wall 5 are curved with the same radius of curvature,

- 2 010237 inwards and outwards in relation to box 1, respectively, as shown in FIG. 4 and 5.

As stated above and shown in FIG. 2, the open container 2 is formed from the bottom wall 4 and the annular side portion 6 of the container, which in the embodiment shown in FIG. 2 has a substantially circular cross-section, as viewed from above. It is necessary to point out once again that box 1 may have other forms of form, as indicated above, and open container 2, in turn, acquires a corresponding form, such as, for example, a cube or a rectangular parallelepiped. As shown in FIG. 2, 4 and 5, the annular side part 6 of the open container 2 may, in turn, include a straight section 8 (conditionally indicated on the drawings), which is adjacent to the bottom wall 4 and is perpendicular to the plane of said bottom wall, and the outer part of which is an annular side surface of a straight cylinder of circular cross section. Outside the side wall is located adjacent to the specified straight section of the edge 9, directed inward and upward, and on a straight section 8 close to the specified edge can also be provided with a narrow edge located at a right angle to the specified straight section. Directly above the edge 9 is a protrusion 10, directed obliquely inward; the upper portion 11 of the protrusion 10 goes obliquely inwards and upwards from the outer edge of the protrusion 10. The outer portion 12 of the side portion is located above the lip 10, with the portion of the side portion having the same shape as the straight portion 8, but somewhat smaller in diameter. The inner part of the annular side part 6 of the container is flat and has no functional parts.

As stated above and shown in FIG. 3-5, the part of the cover adjacent to the top wall 5 of the cover 3 is formed by an annular side part 7 of the cover, which in the embodiment shown in FIG. 3-5, has a substantially circular cross-section, when viewed from above, and which mainly coincides with the side portion 6 of the open container and is located outside said side portion of the container when the box 1 is closed. At the bottom of the inner part of the lid, on the annular side part 7 of the lid, devices 13, in turn, are provided for intermeshing with corresponding devices 10 on the side part 6 of the container in order to fix the lid 3 with respect to the open container 2 when the box 1 is in the closed state. Such devices 10 may, for example, be elements 10, 13 for latching engagement. Such an element 10, 13 for latching engagement is shown in FIG. 5 and in this embodiment of the invention consists of a protrusion 13, which is designed so that when the box 1 is closed, it engages with the protrusion 10 corresponding to it on the side part 6 of the container described above; however, the projections 10 and 13 can abut each other. On the inner side of the side portion 7 of the lid, there may also be several protrusions 14 intended to guide the lid with respect to the side portion 6 of the container. The protrusions 14 shown in FIG. 3, protrude approximately from the transition between the top wall 5 of the cover 3 and the side part 7 of the cover downward along the inner side of the side part 7 of the cover approximately half the height of the side part 7 of the cover. When the box 1 is closed, these protrusions 14 abut against a portion 12 of the outer side of the container side 6.

In accordance with one embodiment of the invention, on the inside of the upper wall 5 of the cover 3, there is a groove 15 adjacent to the annular side part 7 of the cover; the groove 15 is formed by a protrusion 16 having a relatively small height. The groove 15 is wider than the upper edge 17 of the side part 6 of the open container, and when the box 1 is closed, the upper edge 17 abuts against or close to the bottom of the groove 15. In one embodiment of the invention, the upper edge 17 abuts against the bottom of the groove 15 and determines how tightly the side part 6 of the container and the side part 7 of the cover overlap. In addition, the upper edge 17 may have a diameter calculated in such a way that when the box is closed, it lies against the inner side of the side part 7 of the lid and the outer part of the lower part of the protrusion 13, which is directed obliquely downwards and outwards. This design facilitates closure. When closing, the upper edge 17 is pressed against the side part 7 of the lid so that the side of the lid has an elastic pressure mainly outward, at right angles, which considerably facilitates the first stage of the lid installation 1. A thickened cross section can be provided, when viewed from the side , a portion 18 extending from the projection 16 inward toward the center of the lid. The material thickness of this section 18 decreases inward towards the center of the lid and soon passes into the upper wall 5 of the lid 3. Thus, on the inside of the lid a surface 19 is formed, along which the upper edge 17 of the outer portion 12 of the container can slide if lid 3 is installed on the open container 2 with a bias. It was unexpectedly found that this option with the sliding surface 19 in the lid 3 eliminates or at least reduces the number of the problems described above caused by the tilting of the lid 3 when it is installed on the open container 2. The lid 3, which is installed with a skew, can be easily moved; while the upper edge 17 of the side part 6 of the container slides along an inclined surface 19 over the protrusion 16 and enters the groove 15.

The top wall 5, as shown in FIG. 8 may also have a cavity located on the side of the upper wall that does not come into contact with the inside of the box 1, and is formed by the upper wall 5 and the outer lid 20. This allows you to create a smaller closed cavity that can, for example, be used for temporary storage of used parts of snuff An example of a lid containing such a cavity is described in application HUO 2005016036.

As shown in FIG. 9, one of the variants of the box 1 may include a bottom wall 2 in which a protruding portion 21 is provided; thus, a channel 22 is formed around said protruding section inside the side of the container. Such protruding section is described in patent 8E

524025.

The described construction can be modified in various ways in addition to those described in the present application, without departing from the general idea of the present invention. In addition to various options for individual parts, such as elements 10, 13 for locking by snap and guide lugs 14, it is also possible that in a closed box 1, the side part 7 of the cover is located inside the side part 6 of the container, and the functional elements of the cover 3 and capacity 2 are reversed, so that the sliding surface 19 in this case will be part of the container 2. In this case, the described functions and structures will not change otherwise. These and other embodiments of the invention will be apparent to those skilled in the art.
