Description

Expandable gift box

Field of technology

The subject of the technical solution is an openable gift box made of paper, which at small dimensions and low production costs can contain a large number of defined access areas for access to the contained gift items to allow them to be obtained from the box by the user.

Prior art

Gift boxes made of wood, cardboard and plastic are known in the art. Their disadvantage is the high production costs and are therefore unusable, for example, for seasonal products that would be affordable to the widest possible range of users, such as Advent and other calendars.

From the state of the art, a double-sided flat tea calendar is also known from the applicant's patent EP 1790495, in which tea bags are contained for users accessible from both sides of the calendar.

Its disadvantage is that when using tea bags of standard size, it has a relatively large area, which increases costs in production, transport and sale (especially when selling through the e-shop, but also on the area of shelves used in conventional stores). Furthermore, due to its simple planar arrangement, it does not allow for a wider development of graphic and artistic intentions and techniques, such as three-dimensional or moving image structures.

The disadvantage of similar products is also the relatively low strength and resistance to bending and other damage during transport and handling.

For reasons of cost, it is further desirable to be able to produce such a cassette by folding the smallest possible number of sheets of paper, and not to exceed the size of the printing sheet B0, while maintaining or increasing the number of spaces for the gift items contained.

The required number of included gift items is relatively large, for example in the case of popular Advent or monthly calendars it is at least 24, or 31.

The essence of the technical solution

The essence of the technical solution, which solves the above and other problems of the prior art, and at the same time meets the conflicting requirements of better performance while reducing production costs, is an openable gift box containing two flat plates, top plate and bottom plate made of paper, joined by a common back and openable relative to each other around this common ridge, wherein in the closed state of the cassette said two flat plates face each other with their reverse sides and outwardly facing their respective faces, and at least one of the two flat plates comprises on its face and / or reverse sides side at least one defined access area for accessing the gift item to allow the user to retrieve the gift item from the cassette.

In one preferred embodiment, the cassette is arranged for such use that in the closed state of the cassette the lower flat plate lies with its face side on the pad in front of the user, on which the upper flat plate faces upwards, and both plates are at the edges of the plates far from the user is connected by a back, i.e. the free edges of the plates against the back are facing the user. When the user lifts the free edge of the top plate facing each other, the cassette goes into a partially open state, where the two plates form an angle around the spine of, for example, 60 to 120 °, and can

- 1 CZ 34473 UI or it may not be possible, eg due to the use of limiting elements, further opening, eg to an angle between the plates of 180 ° or more. However, the orientation of the cassette can also be adjusted for use as in a classic book, i.e. by the longitudinal axis of the spine facing the user.

The shape of the top flat plate and the bottom flat plate may be a rectangle, a square, or the two plates may have a different shape, and their shape and size may be the same or different. However, the ridge-joined edges of the top plate and the bottom plate must have the shape of a straight line, which may be continuous or interrupted, for example, by an opening in the plates.

The gift box may have a spine formed as a sharp spine, i.e. substantially formed by a single fold (bend) of the paper, as the thickness of the paper allows.

In another embodiment, the back is a flat or rounded back formed by at least two folds of paper. For example, it can contain a total of three fractures, so that the ridge has a third fracture in the middle of its width, or even more fractures. The cassette can thus be more easily opened to an angle between the back (inner) sides of the plates of up to almost 360 °, i.e. by the cassette essentially turning upside down (the back sides in the closed state become face-up in the fully open state).

However, the use of a fixed, eg glued, spine part of another material, such as textile, plastic or a combination thereof with paper, is not excluded. The width of the back can be, for example, from 0.1 mm, resp. as the thickness of the paper allows, up to, for example, one or more cm, as required for space for inserted gift items. More preferably, the top flat side, the bottom flat side and the spine are made of paper, most preferably by cutting a corresponding shape from a single sheet of paper.

Thus, in the simplest case, the cassette comprises two opening plates, with an access surface of any shape and size located anywhere on these plates.

The term "access area" means a defined area on or through which a user has access to a gift item and is intended to include a cartridge embodiment, where the gift item is located entirely on a board surface or other area of the cartridge (typically an adhesive point on the surface). cassette, where the gift article is placed partially on the surface and some parts or parts of its packaging extend below this surface (typically the slits into which the corners of the flat bag are inserted), as well as the cassette design where the gift article is placed below the surface and the access surface contains a window, or closable, through which the user can pull out the gift item.

In one embodiment, the access area on the board may be defined by, for example, a graphic marking such as a frame around its perimeter and / or at least a portion of its area, a mechanical marking (such as blind printing, embossing, perforations, groove, flap, slit), and Adhesive surfaces or adhesive points or snaps, flaps, velcro are placed in the access area as storage elements for gift items. In another embodiment, grooves, flaps, slits or other elements for fastening gift items are placed in the access area as storage elements for gift items, which are packed or unpacked as required. Thus, in such an embodiment, the access area directly comprises a storage element for a gift item, where the object is located at least part of the access area, and the user retrieves the gift item from the access area surface, for example by peeling or pulling corners of the wrapper.

In another embodiment, as will be described in more detail below, the access area on the board may also be defined by, for example, a graphic marking such as a frame, and / or a mechanical marking (e.g. embossing, perforation, blind printing, cutout), but the storage element for the gift item is located. under a corresponding access surface where adhesive surfaces or dots or snaps, velcro, a recess formed in a plastic blister, cut-outs, grooves, slits, or other fasteners for securing gift items, whether or not in a package, may be placed. In such an embodiment, the access surface is typically formed as a window, which may be permanently open in the form of, for example, a rectangular section, or adapted to be opened by a user, for example

- 2 CZ 34473 UI perforations in or around the access area, by cutting a part of the perimeter of the window, a window with a sliding closing element, etc. In this case, the user obtains a gift item from the storage element by pulling the window or opening it through the access area.

In the case of multiple access areas, the access areas can be of the same or different shape and size independently.

The access area (for example a graphically marked area provided with an adhesive point or a cut-out window) can have a shape and dimensions corresponding to the shape and size of the gift object for which it is intended, resp. its projection into the plane of the side of the plate, if it is laid flat on or below it; however, the access area may be larger than the respective gift item, but also smaller. This is the case when the space-saving access areas partially overlap, and thus, for example, flat gift items mounted on the board surface partially overlap. However, the size of the access area is always less than or equal to the size of the side of the board or duplication on which it is located.

Removal from the cassette here means obtaining a gift item from any of the four sides of the cassette opening plates, outer (front) and inner (back), or from the insert described below, it being clear that in the closed state of the cassette only gift items accessible from the outer (front) sides of the cassette opening plates, if such items are present, and in the open or partially open state of the cassette, it is possible to obtain gift items accessible from all four sides of the cassette opening plates and any insert (s).

In another preferred embodiment, the cassette comprises two opening plates, and on each plate there are eight defined access surfaces bounded by printed frames on the front and back, an adhesive point for releasably securing a gift item, such as a tea bag, inside each frame so that the cassette contains a total of 32 access areas for user access to the gift item, to enable its retrieval (peeling off) from the cassette. In another specific embodiment, for example, the tea bags can be inserted with their corners, on one side or even on both sides, into suitably shaped cut-outs of the plates formed in the corresponding access surfaces.

More preferably, the top flat plate, the lower flat plate and the spine are made of paper, most preferably they are formed by a folded cut of a corresponding shape from a single sheet of paper.

Gifts can be, for example, tea bags, treats for children and pets, organic products, pictures of athletes, spices, etc.

By paper is meant here a rigid paper with a basis weight of, for example, above 150 g / m ² , such as cardboard, or even above 250 g / m ² , such as cardboard, preferably smoothed or laminated, most preferably suitable for printing.

The gift box can furthermore advantageously be formed in such a way that the upper flat plate and / or the lower flat plate are doubled by a parallel flat top plate (i.e. a second flat plate), respectively. parallel flat bottom doubling, independently spaced from the respective plates on the front or back of the respective plate, to form a flat cavity for inserting a paper or plastic insert or plastic blister, and the gift box is formed by simply folding this assembly, e.g. . Doubles may also include access areas for access to gift items located on or below the duplicate in the cavity.

In this embodiment, more preferably the top flat plate, the bottom flat plate, the spine, and the respective top doubling and bottom doubling are formed of paper, most preferably formed by a folded cut of a corresponding shape from a single sheet of paper.

In all cases, the necessary bends / breaks of the paper are preferably prepared in advance during production, for example by partial embossing of the paper.

The capacity of the gift box according to the technical solution can be further increased by including an inserted at least one leaf adjacent one edge to the spine, from the spine side adjacent to the reverse (inner) side of the plates, this edge may or may not be connected to the spine. sheet), and wherein said at least one sheet comprises at least one defined access area. In a preferred embodiment, at least a part of the sheet area below the defined access area is doubled for inserting a flat paper or plastic insert or plastic blister (insert or blister is common to multiple access areas / gift items), or for inserting a gift item (a cavity is formed for each gift item individually).

More preferably, the cassette comprises an interposed at least one double-leaf formed by a double-leaf top and a double-leaf bottom, the top and bottom designations being analogous to those described above for top and bottom flat plates, where the two double-leaf parts are folded together by at least part of their length parallel to the spine. from the side of the spine which is adjacent to the reverse side, i.e. the inner side of the plates, the double leaf being openable around this fold. The term "fold" is used herein to distinguish it from other bends / breaks in the bilayer material described below around which the bilayer is not openable. The term "at least part of its length" means that the fold need not be continuous, but may be interrupted by an opening in the double-leaf or a part of the surface of the double-leaf which is not immediately adjacent to the spine, as will be described below.

The at least one double sheet comprises at least one defined access area for accessing the gift item to allow the user to retrieve the gift item from the cassette. Analogously to the plates above, the inner (front) side and the outer (reverse) side are defined for the inserted double sheet, and similarly to the plates above, the definitions apply to the access areas and other elements of the cassette. The fold of the double leaf may or may not be connected to the spine (loosely inserted double leaf).

If the access surface or a part thereof is defined as a window, at least a part of the surface of the double leaf located below such an access surface is provided with a doubling analogously to the upper resp. bottom plates, for inserting a flat paper or plastic insert or a plastic blister (the insert or blister is common for several access areas / gift items), or for inserting a gift item (a cavity is formed for each gift item individually).

In this way it is possible to obtain up to multiples of the number of access areas, and / or to achieve an increase in their dimensions, depending on whether the inserted double sheet is connected (for example glued) to the back (inner) side (s) of the plates by its front side (s), or, in the case of multiple inserted double sheets, whether adjacent faces of the double sheets are joined (e.g. glued).

The sheets (double sheets) may be combined with each other, and independently may or may not be connected to the spine, and may be the same size as the plates, or even smaller in order not to protrude from the space between the plates, and independently the same or different shape. The sheets (two sheets) are most preferably made of paper.

The term "double leaf fully unfolded" means a position of the double leaf where its top and bottom lie in one plane, i.e. make a straight angle of 180 ° around the fold, for example just after cutting from a sheet of paper or opening a gift box.

The double-leaf folded state means a partially folded state, in which the upper and lower parts form an obtuse or acute angle around the fold, as well as a fully folded state, in which the upper and lower parts form an angle of 0 ° around the fold, i.e. they essentially lie on top of each other.

The term "cut" in the usual sense refers to an interruption (e.g. cutting) of a sheet material, where the material on one side of the interruption is removed. The term "intersection" refers to an interruption of sheet material, where material remains present in the product on both sides of the interruption.

- 4 CZ 34473 UI

Another preferred embodiment is a gift box in which the bilayer comprises at least one pair of bilayer slits, wherein both slits of at least one of the pairs of slits pass, with the bead fully unfolded in the plane, over the longitudinal axis of the fold connecting the top of the blister and the bottom of the blister. the fold sheet), and at the same time the bilayer contains at least three folds of material which are straight (but may be continuous or interrupted by an opening, for example), parallel to the longitudinal axis of the fold and different from the fold, i.e. the blister is not opening around these folds, and are located between a corresponding pair of intersections (i.e. between or between the endpoints of the intersections, the pairs of intersections having a corresponding shape and spacing and the fractures having a corresponding spacing for spacing at least one of the fractures, together with the bilayer material located around the fracture between the pair of intersections) from the longitudinal axis and for the exit of this quarry into a part of the space delimited by the planes enclosed by incl part of the double-leaf and the lower part of the double-leaf, when closing the double-leaf unfolded in a plane around the fold into a folded state.

The closing process typically occurs for the first time after the manufacture of the cassette, or after its filling with gift objects, when it is usually necessary to move the quarry at the beginning, which is to protrude into the space, away from the plane of the fully distributed double-leaf.

It is clear that as the double sheet continues to close in a partially folded state, the angle to fold the double sheet formed by the surfaces of the material on opposite sides of the fracture protruding into space will gradually tighten, said surfaces of material remaining still flat, and in the fully folded state of the cassette. the upper and lower parts of the double leaf together form an angle of 0 ° around the fold facing away from the double leaf fold, the surfaces of the material on opposite sides of the fracture projecting into space will also form an angle of 0 ° around this fracture but towards the double leaf fold.

Similarly, typically when the cassette is opened by a user, the fracture emerges into space from the plane of the double-sheet material in the opposite manner, and the process of opening and closing to form three-dimensional structures can be repeated as desired.

In a preferred embodiment of the gift box, the folds are formed as pre-prepared partial recesses or perforations of the double-leaf material to facilitate the initial assembly of the box and its opening and closing in use.

In another embodiment of the cassette, the inserted double sheet may have its upper part connected, for example glued, to the reverse side of the top plate of the cassette, or in the case of a double embodiment with a top double. If several inserted double sheets are present, this inserted double sheet may have the upper part joined, for example glued, to the lower part of the previous double sheet. The same inserted double sheet may have its lower part connected to the bottom plate, the bottom doubling or, in the case of several inserted double sheets, to the top part of the following double sheet.

This reduces the space for the access areas, but automatically opens the double sheet around the fold when the cassette is opened or, in the case of several inserted double sheets, when the adjacent open double sheet is closed. Conversely, an increase in the space for the access areas is obtained due to the fact that the access areas in various embodiments can be placed on any part of the double sheet, including the areas protruding when the cassette is opened into the space.
