Description

The present invention relates to a folding box made of a one-piece, in the basic state flat base body, which in a folded state defines an inner pocket for receiving removable, light-sensitive cloths, comprising at least five panels which are laterally separated from one another by longitudinal fold lines, the first, third and fifth panel have substantially the same width, and the second and fourth panels have substantially the same width, and wherein on the first to fourth panels upper and lower tabs are hinged to an upper and lower horizontal fold line so that the upper and lower Tabs can form upper or lower walls, a tear line leading from the first panel through the second panel to the third panel and bordering a central horizontal fold line in the fourth panel, in order to provide a tear-open hinged lid.

Boxes for holding light-sensitive wipes are known in the prior art. However, these boxes normally allow unimpeded light to enter the contents through the opening provided for removing the wipes. In addition, a closed box can often inadvertently open partially or completely, for example due to mechanical tension in the area of a lid part, which also enables undesired incidence of light. The publication FR 2 818 958 A1 discloses a folding box, which consists of a one-piece, in the basic state flat base body, and which defines an inner pocket in a folded state.

The object of the present invention is to provide an improved folding box.

In a first aspect, the present invention is directed to such a folding box according to claim 1.

This provides a folding box with improved mechanical integrity, in which less light can also penetrate into the interior of the folding box due to the double wall.

A preferred embodiment of the invention provides that an upper edge of the sixth panel is arranged above the tear line in the second panel, in order to provide a light protection wall.

This makes it possible, in particular when storing light-sensitive content that protrudes into the region of the horizontal tear line, to open the hinged lid and to remove content without the light being able to enter the content directly, or at least being greatly reduced.

A lower edge of the sixth panel is further preferably arranged above the lower horizontal fold line.

This saves material, particularly in terms of production technology, since the light protection function of the sixth panel is primarily fulfilled by the part protruding beyond the horizontal tear line. For this purpose in particular, it is not necessary for the sixth panel to extend to the lower horizontal fold line in the folded state.

According to the invention, the fifth and seventh panels have guide elements projecting longitudinally over the sixth panel, for guiding and latching the hinged lid when opening and closing.

This at the same time provides a snap-in function which, together with the light protection function of the sixth panel, provides improved light protection since the hinged lid is less easy to open by itself, for example due to mechanical stresses in the upper horizontal fold line of the fourth panel. Thus, light-sensitive content is better protected against the incidence of light.

This embodiment is preferably improved in that the guide elements are each divided by tear lines into a part that cannot be detached from the fifth or seventh panel and a detachable part that is complementary thereto, for gluing into the hinged cover and for guiding and latching with the non-detachable part.

If the hinged lid is closed again after opening for the first time, the detachable and the non-detachable part only lie close together, separated by the opened tear line, and thus provide a snap-in function. This applies all the more if the detachable parts have concave or convex shapes that are complementary to the non-detachable parts. Even before snapping into the closed position, the edges of the detachable and non-detachable edges rub against one another, thereby guiding the movement when opening or closing, which further simplifies the actuation of the folding box.

The insertion of content, such as light-sensitive cloths, into the inside of the folding box is also simplified because the detachable part is glued to the inside of the hinged lid and therefore cannot protrude freely in the area of the hinged lid. The folding box is filled by placing the contents through the upper ones, which are still parallel to panels one to four Tabs are inserted into the folding box, parts of the guide elements that protrude inwards could block the way. In particular, automated filling could be significantly hampered.

According to the invention, the tear lines in the fifth and seventh panels in the folded state protrude below the tear lines in the first and third panels, for protection from light by the detachable parts when the hinged lid is open.

This enables the detachable parts glued into the hinged lid to protrude into the open gap between the hinged lid and the light protection wall or the guide elements, even with a partially or completely opened hinged lid, so that they also contribute to improved light protection of the inside of the folding box.

A further improvement of the invention provides that at least one of the longitudinal fold lines of the sixth panel in the area of the light protection wall is interrupted by a preferably arch-shaped holding element protruding laterally from the sixth panel.

As a result, when the fifth and seventh panels are bent at right angles in the folded state, the holding element protrudes laterally parallel to the sixth panel, i.e. perpendicularly to the seventh and fifth panels, respectively, and engages in the hinged lid in order to close it in the closed position hold.

At least one of the longitudinal fold lines of the sixth panel is particularly preferably interrupted by recesses.

This means that the respective fold line or both fold lines are structurally weakened, i.e. easier to fold, and that the respective fold line (s) puts less tension on the adjacent panels, so that they protrude less arched, but rather completely in flat planes oriented at right angles to one another are arranged. This is particularly advantageous since the fifth, sixth and seventh panels are arranged on the inside of the folding box and are in direct contact with the third, second and first panels, respectively, whereby a curvature could exceed manufacturing tolerances.

The upper edge of the sixth panel is particularly preferably arranged at least 5 mm, 10 mm, 15 mm or 20 mm above the tear line in the second panel. The top edge of the sixth panel is likewise preferably arranged at approximately 25%, 50%, 75% or 100% of the height of the guide elements above the tear line.

Preferred heights of the light protection wall are thereby realized. If the guide elements have rounded corners, it is further preferred to arrange the upper edge of the sixth panel at the base of the rounded corners.

The tear line in the second panel particularly preferably has a bulge which overlaps the light protection wall, in order to provide a supported engagement point.

This allows the tear line to be opened easily without damaging parts of the folding box or the hinged lid.

The invention is explained in more detail below with reference to the figure.

According to the figure , the base body 8, which is flat in the basic state shown, of a folding box 9, which in a folded state defines an inner pocket for accommodating removable, light-sensitive cloths, is formed in one piece and comprises in particular a first panel 1, a second panel 2, a third panel 3 , a fourth panel 4, a fifth panel 5, a sixth panel 6 and a seventh panel 7, which are laterally separated from one another by longitudinal fold lines 10-15.

The first, third, fifth and seventh panels 1, 3, 5, 7 have essentially the same width, the fifth and seventh panels 5, 7 having a somewhat smaller width, approximately by the thickness or twice the thickness of the flat base body 8 reduced. Likewise, the second, fourth and sixth panels 2, 4, 6 have essentially the same width, the sixth panel 6 having a somewhat smaller width.

On the first to fourth panels 1, 2, 3, 4, upper flaps 16 and lower flaps 17 are articulated on an upper horizontal folding line 18 and on a lower horizontal folding line 19, so that the upper flaps 16 have upper walls and the lower flaps 17 lower Can form walls by folding them at right angles along the respective fold lines and gluing them together, for example.

A tear line 20 in the form of a perforated line leads from the first panel 1 through the second panel 2 to the third panel 3 and adjoins a central horizontal fold line 22 in the fourth panel 4 to provide a tear-open hinged cover 23.

As a result, the panels five, six and seven 5, 6, 7 can each be folded inwards at right angles over the respective longitudinal fold lines 13, 14, 15 such that they are inside the four, three, two and one 4 through the panels , 3, 2, 1 formed outer walls, whereby a spirally folded folding box 9 is realized.

The upper edge 24 of the sixth panel is arranged above the tear line 20 in the second panel - represented by a dotted line 25, which represents a projection of this tear line 20 in the second panel 2 in the folded state - in order to provide a light protection wall 26. The lower edge 27 the sixth panel is arranged slightly above the lower horizontal fold line 19, which does not impair the light protection function.

The fifth and seventh panels 5, 7 have guide elements 28, 29 projecting longitudinally beyond the sixth panel 6, which guide the hinged lid 23 when opening and closing and finally engage in the folded state (not shown further here). In particular, the guide elements 28, 29 prevent the hinged lid 23 from opening by itself, or from mechanical tension, for example in the middle horizontal fold line 22, from opening at least over an angle, starting from the light between the hinged lid 23 and the light protection wall 26 could kick.

The guide elements 28, 29 are each divided by tear lines 30, 31 in the form of perforated lines into a part 28a, 29a, which cannot be detached from the fifth or seventh panel 5, 7, and a complementary detachable part 28b, 29b, which - here not shown - folded state in the hinged cover 23, in particular in the panels one 1 and three 3, glued, whereby the detachable parts 28b, 29b interact with the non-detachable parts 28a, 29a for guiding and latching the hinged cover 23, in particular along of the tear lines 30, 31. The tear lines 30, 31 in the fifth and seventh panels 5, 7 in the folded state are partially congruent with the tear line 20 in the first and third panels 1, 3, so that tear lines 20, 30, 31 are torn simultaneously can be.

Alternatively - not shown further here - the tear lines 30, 31 in the fifth and seventh panels 5, 7 can protrude below the tear lines 2 in the first and third panels 1, 3 in the folded state, for light protection by the detachable parts 28b, 29b when the hinged lid is open 23. For this purpose, the tear lines 30, 31 could, for example, be drawn further down or unloaded further down.

The longitudinal fold lines 14, 15 of the sixth panel 6 in the region of the light protection wall 26 are interrupted by arcuate holding elements 32, 33 protruding laterally from the sixth panel 6. These rub when opening and closing the hinged lid 23 in the folded state on the inside of the hinged lid 23 and thus stabilize it.

The longitudinal folding lines 14, 15 which lie against the sixth panel 6 and define it are interrupted by recesses 34 which are elongated and which curvature in particular of the fifth, sixth and seventh panels 5, 6, 7 by reducing the mechanical hysteresis of the folding lines 14, 15 reduce when folding.

The tear line 20 furthermore has, in the second panel 2, a bulge 35 which overlaps the light protection wall 26 and which, in the folded state (not shown here), serves to provide a supported engagement point.

The invention is not restricted to the above exemplary embodiments. Rather, it extends to other forms of training, which are covered by the following patent claims. For example, the folding box can be made of paper, cardboard and / or plastic.
