EP2228310B1 - Blank for packaging with latching flap lid - Google Patents

Description

The present invention relates to a one-piece blank for forming a parallelepiped-shaped package with top flap pivotable about a trailing edge according to the preamble of claim 1 and a producible from such a blank package.

From the CH 534 616 The Applicant is known a box-shaped packaging with hinged lid, the front flap and side tabs grip with the lid closed over the end wall and side wall of the box body. The packaging further comprises a locking tab disposed on the front side of the box body, by which the hinged lid is held in its closed position, wherein the locking tab is disengaged when the lid is opened. For locking the locking tab in the hinged lid two locking edges are present on its inside end wall, behind which engages the locking tab when closing the hinged lid. By such a package is permanently taken care of a good backup of the hinged lid in its closed position and it allows the user a repeated opening and reliable closure of the hinged lid.

Conventionally, a one-piece paper or board-containing blank is used for packaging production, which has individual fields and tabs, which are suitable for folding and gluing. However, the manufacture of a package described above is made more difficult by the fact that additional care must be taken in the blank for the arrangement of the locking tab and the locking edges. In particular, by the added folding operations, the processing of such a blank within a machine Manufacturing process and a machine-compatible filling of the packaging to be problematic.

The EP 0 443 930 A1 discloses a blank for a carton having a locking mechanism of two locking tabs and two locking edges. The locking edges are formed in side lobes, which are laterally connected to the Deckelstirnfelds. The locking tabs are located at the top of sidewall panels that are juxtaposed in the cross-direction of the blank with respect to the longitudinally interfacing lid end panel and lid panel. The different alignment in the juxtaposition of the midfield and a concomitant complicated arrangement of outer lobes at these midfields makes the folding of the blank much more difficult.

In the US 2,777,629 Folded carton has a locking mechanism which consists of only one box-side locking tab and only one cover-side locking edge. For reliable reclosability of the carton, however, a closure mechanism with doubly lockable double-formed locking edge is preferable.

An object of the present invention is to provide a blank of the type mentioned, by which known blanks of this type can be replaced and allows a machine-compatible processing and filling of the packaging to be formed by means of common vertical and horizontal filling machines.

Such a blank is specified in claim 1. The other claims indicate preferred embodiments of this blank as well as a packaging produced therefrom.

Thus, the blank according to the invention comprises a series of fields, which are connected to each other in pairs via parallel longitudinal fold lines, so that the row of fields can be brought into a three-dimensional shape in a first longitudinal folding process. The resulting lateral openings allow a vertical or horizontal filling of this three-dimensional body. In the array of fields next to the lid frontal field and the lidded roof panel, essential elements for forming the lower packaging part are preferably arranged, in particular a rear wall panel, a bottom panel adjoining thereto and an end wall panel adjoining thereto.

Furthermore, the blank according to the invention comprises a plurality of fold-in flaps, in particular cover side flaps and / or side wall flaps of the packaging lower part, which are each connected to opposite outer edges of individual panels via a transverse fold line running perpendicular to the longitudinal fold lines. This can be in a subsequent Querfaltvorgang the intended Form packaging cubes and glue them to the intended surfaces. The attaching to the lid frontal Einfaltlappen are suitable for forming the locking edges and at the same time form an inside fixation of the hinged lid, which can be created without additional longitudinal folding.

Preferably, only the packaging parts which can be provided with a tapering or rounding or other types of structures, by means of which the Querfaltbarkeit is facilitated, while straight-edged and / or sharp-edged packaging sections are arranged within the longitudinally foldable array of fields by attaching to each field Einfaltlappen ,

To form the locking edges, various embodiments of the folding laps are conceivable. According to a first embodiment, the folding-in tabs are designed as adhesive tabs so that they can be bonded together with the lid side tabs during the formation of the packaging. In this case, the locking edges are formed by the side edges of the adhesive tabs facing the blank in the blank. These act after production of the package with the lid closed, each with a locking tab in the side region of the packaging base together. The side according to this variant arrangement of the locking tabs allows a particularly reliable locking of the hinged lid, as they are spaced from the intended handling surface on the lid end face and thus little affected by force effects in the handling of the lid. Such locking tabs may be connected in the blank, for example, on the side wall tabs in each case via a Querfaltlinie. Since she is two times are formed and cooperate with only one locking edge, they can be small in size. As a result, the force required for the Querfaltvorgang when forming the locking tab is low, which is particularly advantageous for smaller packaging dimensions. For example, in the case of packages with a side wall height smaller than 2 cm, the formation of such a locking tab can take place without damaging the side wall.

According to a second embodiment, two transverse fold lines are indicated on the fold-in tabs, by which they are subdivided into in each case three area sections. The respective adjacent to the lid end panel inner surface portions are formed as adhesive tabs, so that they can be bonded during formation of the package with the lid side lobes. Along the two transverse fold lines, a folding back of the fold-in folds is made possible so that the respectively central surface section comes to lie on the inner surface section and the respective outer surface section rests in the lid frontal field. Such an advantageous stabilization of the hinged lid thus formed is achieved in the front end edge regions. In addition, the locking edges are formed by the side edges of the surface portions lying in the lid frontal field. These act after production of the package with the lid closed with at least one locking tab in the front region of the packaging base together. The locking tab can be provided in the blank, for example, at the end of the row of fields to the end wall field subsequently. Such a locking tab can also be used in packaging with a comparatively small end wall height of, for example, less than 2 cm, but preferably the end wall height is at least 2 cm to one Damage to the end wall when machine forming the locking tab to avoid.

Due to the advantageous arrangement of the locking edges and locking tab, the blank described can still be extended while maintaining machine-compatible processability, in order to allow the formation of a package which has at least one additional functionality in addition to the latching mechanism of the hinged lid. For example, in the field row to the lid frontal field then a double bottom field can be arranged, which can be bonded to the bottom field when forming the package. Therein, for example, a first-opening securing of the packaging is realized by arranging a tear-open strip on the longitudinal folding edge between the double bottom panel and the lid front panel. Alternatively, a first opening safety device can be formed by a perforated connecting region in the end wall field, which can be bonded to the lid end field during the formation of the packaging and is torn open by the first opening of the hinged lid.

The Fig. 1 shows the lying in a plane one-piece blank 1 a carton for producing a cuboid packaging with a hinged lid. The blank is formed in its essential part of paper or cardboard-like material. The course of the fold lines is indicated on the blank by solid or dashed lines. Preferably, the blank is provided along the fold lines with grooves or other structures facilitating wrinkles. Along each fold line two adjoining sections of the blank are connected to each other. Areas provided with a bonding agent, in particular adhesive, are identified by hatched areas. For better clarity, the boundary lines of these adhesive surfaces are shown such that they either protrude slightly beyond the relevant structures of the blank or lie within these structures, depending on the application, a partial or complete coverage of the structures with the connecting means is possible.

In its middle region, the blank 1 consists of a row of fields 2 which are rectangular in their overall contour and in which a plurality of substantially equal length fields 3 - 8 are connected by parallel longitudinal fold lines 9 - 13. The row of fields comprises a lid end field 3 arranged at the end, a lidded roof field 4 adjoining thereto, a rear wall panel 5 adjoining thereto, a bottom panel 6 adjoining thereto, an end wall panel 7 adjoining thereto and an end-side opposing wall panel 8 adjoining thereto.

The lid roof panel 4 and the bottom panel 6 have a substantially identical rectangular shape. Their transverse length, by which one broad side of the packaging cuboid to be formed is determined in each case, is more than twice as large as in the other fields. Likewise, the rear wall panel 5 and the end wall panel 7 are formed substantially identical in their rectangular outer contour, to each form a narrow side of the packaging cuboid.

The lid end panel 3 has in comparison to the end wall panel 7 only a little shorter transverse length. It is thereby achieved that, after the packaging has been formed, the lid end panel 3 engages over the front wall panel 7 over a large area when the hinged lid is closed. At its free end, the lid end panel 3 is provided with a centrally disposed curved recess 14 which forms a handling means for opening the hinged lid.

The end wall panel 7 has at its adjoining the Gegenwandungsfeld 8 end a centrally disposed, elongated perforated portion 15 which is provided as an intended adhesive surface with a connecting means. By longitudinal folding at the longitudinal folding edge 13 can be the Gegenwandungsfeld 8 wrap inside the front wall panel 7 hang up and stick to the adhesive surface, creating a double-walled reinforcement of Stirnwandfelds 7 is ensured, which is claimed in handling the manufactured packaging the most. In addition, an inner-walled covering of the perforated connection region 15 is thereby achieved, so that after a tearing off of the perforation 15, the end wall of the packaging is not broken.

At the directly sequenced fields 3 - 7 of the row of fields 2, two essentially identically formed Einfaltlappen 16 a - 20 a and 16 b - 20 b are attached to their respective opposite transverse outer edges. The fold-in flaps 16a-20a or 16b-20b are in each case connected to the fields 3-7 over their entire transverse length by way of an associated transverse fold line 22a-26a or 22b-26b which runs perpendicular to the longitudinal fold lines 9-13.

The fold-in tabs 18a, 18b and 20a, 20b which adjoin the rear wall panel 5 and the end wall panel 7 on both sides are substantially identical to the tabs which form a wedge-shaped tapering outwardly. As a result, a simplified transverse folding and insertion of the same is ensured in the packaging to be formed bottom part. The fold-in tabs adjoining the bottom panel 6 on both sides are provided for bonding with the adhesive tabs 18a, 18b and 20a, 20b, whereby the side walls of the pack bottom part are formed, and are referred to below as side wall tabs 19a, 19b. By an advantageous rounding of their exposed corners a simplified transverse folding is guaranteed here.

On the side wall tabs 19a, 19b, a locking tab 21a, 21b is in each case in the region of their opposite free outer edges present. By a further perpendicular to the longitudinal fold lines 9 - 13 extending transverse fold line 27a, 27b folding them is made possible in the Verpackungsaussenraum, so that their exposed outer edge is directed downward. The transverse fold lines 27a, 27b are therefore preferably arranged as a cut on the underside of the blank 1, whereby an opposite transverse folding with respect to the other transverse fold lines 22a-26a or 22b-26b is simplified. The locking tabs 21a, 21b are arranged in the front half of the front wall 7, preferably in the front third, of the transverse length of the side wall tabs 19a, 19b, thereby allowing cooperation with locking edges arranged in the lid interior. Their exposed outer edge each has a rounded contour, whereby on the one hand increased Querfaltbarkeit and on the other hand adaptation to the contour of the associated locking edges is achieved. The cross-folding of the locking tabs 21a, 21b, which can be easily carried out by machine, is further ensured by its dimensioning, in that its maximum dimension through the central region of its rounded outer contour in the direction of the longitudinal folding lines 9 - 13 does not correspond to less than one third of its transverse length to be folded. For example, their transverse length can be about 1.5 cm and their maximum longitudinally parallel dimension about 0.6 cm.

The associated locking edges 28a, 28b are provided on the Einfaltlappen 16a, 16b, which are in communication with the Deckelstirnfeld 3 on the two-sided Querfaltlinien 16a, 16b. In extension of its front edge, each of the fold-in tabs 16a, 16b essentially adjoins the free edge of the lid end panel 3. The Locking edges 28a, 28b are formed along recesses in the region of the fold-in flaps 16a, 16b facing the lidded roof panel 4, which are adapted to the outer contour of the respectively associated locking tabs 21a, 21b by their rounded, outwardly tapering shape. The corners of the savings facing the cover roof panel 4 also have a rounding, so as to facilitate the folding of the fold-in tabs 16a, 16b in the transverse direction. The Einfaltlappen 16a, 16b are formed as adhesive tabs to be bonded to form the hinged lid with the rear side of the cover side flaps 17a, 17b.

The lid side walls are formed by the Einfaltlappen 17a, 17b, which are connected to the lidded roof panel 4 by the Querfaltlinien 23a, 23b and hereinafter referred to as lid side tabs. The length of the cover side tabs 17a, 17b corresponds in its frontal third substantially the transverse length of the Deckelstirnfelds 3, wherein the Querfaltbarkeit is increased by a thin saving along the front edge and a rounding of the exposed corners. The region adjoining the end-side transverse longitudinal third region has a rectilinearly running taper, which covers more than two thirds of the transverse length, so that the rear end of the cover side tabs 17a, 17b opens almost into the rear wall panel 5. As a result, the pivotability of the hinged lid to be formed is increased and tilting of the same on the lower packaging part is advantageously avoided.

The Figg. FIGS. 2 and 3 show a packaging 30 made from the blank 1 and consisting of an upper side, ie hinged lid 31 located on the upper side of the packaging, and a lower packaging part 32, the hinged lid 31 in FIG Fig. 2 in open and in Fig. 3 in closed State is shown. In the illustration in Fig. 2 In particular, the functionality of the package 30 of a secure reclosability by the laterally disposed locking tabs 21a, 21b and the respectively associated lid inner side locking edges 28a, 28b can be seen. Likewise, the functionality of a first opening assurance by means of the perforated connection portion 15, which is entrained during the first opening of the package 30 with the hinged lid 31, so that in the torn-out area the Gegenwandungsfeld 8 comes to light. The narrow sides of the packaging cuboid 30 formed from the end wall panel 7, the rear wall panel 5 and the side wall tabs 19a, 19b have a width of approximately 2 cm, while the broad sides formed from the lidded roof panel and the bottom panel have a width of approximately 4.5 cm, wherein the longitudinal diameter of the cuboid 30 is about 8 cm.

During the production and filling of the package 30, an oblique angle folding or approximate rectangular folding of the panels 3 - 7 along the longitudinal fold lines 9 - 12 in the same folding direction towards the rear side of the blank 1, as well as a complete folding of the opposing wall panel 8 along the longitudinal fold line 13, takes place in the same same folding direction, so that the opposing wall panel 8 come to rest on the back of Stirnwandfelds 7 and the front of Stirnwandfelds 7 on the back of the Deckelstirnfelds 3. Subsequently, the surfaces resting on one another are glued together. In particular, only the perforated connection region 15 of the end wall panel 7 is adhesively bonded to the rear side of the lid end panel 3, whereby the first opening safeguard is formed by entraining only the perforated region 15 when the lid 31 is opened for the first time. The thus shaped three-dimensional body has lateral openings along the still unfolded Einfaltlappen 16a - 20a, 16b - 20b, whereby a vertical filling of the same is made possible. The locking tabs 21a, 21b are now approximated by a substantially complete refolding along the fold-back fold lines 27a, 27b formed on the front side of the side flaps 19a, 19b and thus brought into their locking position. Following this, the packaging cuboid 30 is completely formed by folding the folding tabs 16a-20a or 16b-20b along the transverse folding lines 22a-26a or 22b-26b by a right-angled folding in the direction of the interior of the basic body and against the intended adhesive surfaces 16a, 16b , 18a, 18b, 20a, 20b are glued together. The particularly simple production of the package 30 from the blank 1 therefore only requires one longitudinal fold for each field of the row of fields 2 and only one transverse fold of the two respectively associated fold-in tabs, with an additional fold-back folding of the locking tabs 21a, 21b to be performed only once.

The in Fig. 4 The blank 40 shown also consists in its central region of a substantially in their overall contour rectangular array 41, in which a plurality of substantially equal length fields 42 - 47 related to each other via parallel Längsfaltlinien 48 - 52. The rows of fields comprise a bottom floor panel 42 arranged at the end, a cover end field 43 adjoining thereto, a cover roof panel 44 adjoining thereto, a back wall panel 45 adjoining thereto, a bottom panel 46 adjoining thereto and an end wall panel 47 adjoining thereto. The panels 43-47 essentially correspond in their outer contour Fields 3 - 7 of the Fig. 1 blank 1 shown and explained above, wherein in the end wall panel 47, no perforated connection portion is formed and the Bottom panel 46 is provided as an adhesive surface with a connecting means to allow after performing the longitudinal folding sticking to the raised bottom panel 42 lying thereon.

At the directly successive rows 43-47 of the row of fields 41, two essentially identically formed fold-in tabs 56a-60a or 56b-60b are attached to their respective opposite transverse outer edges. The fold-in flaps 56a-60a or 56b-60b are in each case connected to the fields 43-47 over their entire transverse length via an associated perpendicular transverse fold line 62a-66a or 62b-66b extending perpendicular to the longitudinal fold lines 48-52. The lid side tabs 57a, 57b attached to the lid panel 44 and the side wall tabs 59a, 59b attached to the bottom panel are substantially identical in their outer contour to the lid side tabs 17a, 17b and the side wall tabs 19a, 19b of FIG Fig. 1 formed blank 1 is formed. The fold-in tabs 58a, 58b and 60a, 60b respectively attached to the rear wall panel 45 and to the end wall panel 47 are substantially identical to the adhesive tabs 18a, 18b and 20a, 20b of FIG Fig. 1 formed blank 1, wherein its outer contour, however, has no rectilinear outward taper. Instead, an increased Querfaltbarkeit is ensured by thin substantially longitudinally parallel recesses at its two side edges. The recesses are each bounded on the inside by a widened connection mouth to the back wall panel 45 and to the end wall panel 47. On the outside, the recesses facing the side wall tabs 59a, 59b are limited by end support extensions to the edge surface support of the fold-in tabs 58a, 58b or 60a, 60b on the bottom panel 46 during the production of the package.

To the end wall panel 47 is over a gegenfaltbare, i. Foldable to the front of the blank 40, also longitudinally parallel arranged longitudinal fold line 53, a locking tab 54 is connected. The locking tab 54 extends over a majority, more precisely about two-thirds, of the end edge length of the endwall panel 47 within its central region. Its transverse length corresponds approximately to one third of the transverse length of the end wall panel 47 and is in absolute values about 1 cm, whereby a longitudinal foldability of the same is made possible by common packaging machines. The dimensioning of the openings formed on the outside of the locking tab 54 thus formed is selected such that engagement of the locking tab 54 in associated locking edges 68a, 68b on the fold-in tabs 56a, 56b is made possible. By a respective rectilinear taper along the outer sides of the locking tab 54, which is also provided in each case complementary in the Einfaltlappen 56 a, 56 b in the region of the locking edges 68 a, 68 b, this engagement mechanism is advantageously supported.

The fold-in tabs 56a, 56b, which are connected to the lid end panel 43 via the transverse fold lines 62a, 62b, respectively, have two further transverse fold lines 69a, 70a, 69b, 70b, respectively, through which they are subdivided into three substantially equal surface sections 71a, respectively. 73a and 71b - 73b is achieved. The transverse fold lines 70a, 70b, which are respectively arranged on the outside, are provided in the direction of the front side of the blank 40, for example by arranging a perforation on the back side of the blank 40, for counterfolding the respective outer surface section 73a, 73b. The transverse fold lines 69a, 69b arranged on the inside are, like the remaining transverse fold lines 62a - 66a or 62 b - 66 b of the blank 40, provided for transverse folding in the direction of the rear side of the blank 40.

In this way, during the formation of the package, a so-called zig-zag folding of the folding tabs 56a, 56b may be carried out, in which a complete folding is carried out along the inside arranged transverse fold lines 69a, 69b, so that the middle surface sections 72a, 72b on the rear side of the inner surface portions 71a, 71b come to coincide with each other and along the outside arranged Querfaltlinien 70a, 70b a rückckwinklige refolding is performed, whereby the respective outer surface portions 73a, 73b orthogonal to the front of the central surface portions 72a, 72b protrude. By suitable adhesive surfaces now formed with a double wall thickness Einfaltlappen 56a, 56b are fixed. The foldability along the transverse fold lines 69a, 69b arranged on the inside is increased, in particular, by means of a centrally arranged circular opening and an end-face wedge-shaped saving.

The locking edges 68a, 68b are respectively arranged on the free corner of the outer surface portion 73a, 73b which faces the lid end field 44 and which, after the zigzag folding, projects orthogonally from the respective central surface portion 72a, 72b. They are each formed by shaping savings, which are adapted to the transverse length of the locking tab 54 and the outside wedge-shaped taper. The inner surface portions 71a, 71b are formed on the front side as adhesive tabs and are thus after a Rechtswinkelfaltung on the rear side of the cover side tabs 57a, 57b after a rectangular folding of the same fixable. In this case, the respective central surface portion 72a, 72b lies on the rear side of the also folded at right angles Lid stop box 43, so that the locking edges 68a, 68b are brought into their intended position for cooperation with the end wall-side locking tab 54. Due to the double-walled design of the zig-zag folded fold-in tabs 56a, 56b, the stability in the end-side corner regions of the hinged lid thus formed is increased.

At one end of the row of fields 41, the double bottom panel 42 is arranged following the lid frontal field 43, whose outer contour substantially corresponds to the bottom panel 46 and which can be fixed on its adhesive surface. The longitudinal fold line 48 between the double bottom field 42 and the lid end field 43 is designed to be rupturable by a special perforation. In less than fingerbreiter spacing to the longitudinal fold line 48 a parallel thereto further tearable perforation line is formed. In the less than fingerbreiten range between the two perforation thus a Aufreisstreifen 55 is realized, is formed by the first opening securing the package at the first opening of the hinged lid. On an outside, the perforation lines open into wedge-shaped recesses, which allow easier manual access to the tear strip 55.

The Figg. FIGS. 5 and 6 show a packaging 80 made from the blank 40, consisting of an upper-side hinged lid 81 and a lower packaging part 82, the hinged lid 81 in FIG Fig. 5 in open and in Fig. 6 is shown in the closed state. In the illustration in Fig. 6 In particular, the functionality of the package 80 is a secure reclosable work by the frontally arranged locking tab 54 and the associated inner lid locking edges 58 a, 58b can be seen. The narrow sides of the packaging cuboid 80 formed from the end wall panel 47, the rear wall panel 45 and the side wall tabs 59a, 59b have a width of about 3 cm, while the broad sides formed from the lidded roof panel and the bottom panel have a width of about 8.5 cm, wherein the longitudinal diameter of the cuboid 30 is about 12.5 cm.

In the production of the package 80, a rectangular folding of the panels 42-47 takes place along the longitudinal fold lines 48-52 in the same folding direction in the direction of the rear side of the blank 41, as well as a substantially complete counterfolding of the locking tab 54 in the direction of the front side of the blank 41 along the longitudinal fold line 13 in the same same folding direction. In this case, the front of the bottom panel 46 comes to rest on the back of the lid front panel 42 and the two surfaces resting on one another are glued together. The base body thus formed has lateral openings along the unfolded fold-in tabs 56a-60a and 56b-60b, respectively, allowing for vertical filling thereof. Now, the above-explained zig-zag folding of the Einfaltlappen 56a, 56b, so that the locking edges 68a, 68b are directed away from the inside arranged Querfaltlinien 69a, 69b orthogonal. Following this, the packaging cuboid 80 is completely formed by folding the folding tabs 56a-60a or 56b-60b along the transverse folding lines 62a-66a or 62b-66b by a right-angled folding in the direction of the interior of the basic body and against the intended adhesive surfaces 71a, 71b , 58a, 58b, 60a, 60b are glued together. The particularly simple production of the package 80 from the blank 1 thus requires only one longitudinal fold for each field of the field row 2 and only one each Cross folding of the two respectively associated Einfaltlappen, with an additional only once to be performed counterfolding of the locking tab 54 and a zig-zag folding of the Einfaltlappen 56a, 56b.

In a machine-oriented processing, the blank 1, 40 is rolled up in a first step in a gluing machine in the extension direction of the row of fields 2, 41, wherein a first folding along the intended longitudinal fold lines is performed, thereby creating a three-dimensional substantially parallelepiped basic body. In the second step, this basic body is fixed by means of the respective adhesive surface 15, 46 provided on at least one field of the rows of fields 2, 41. Since the Einfaltlappen are still in the unfolded state, a conventional machine-vertical filling of the packaging to be formed can be carried out in the third step through the lateral openings of the body thus formed. In the fourth step, the machine-appropriate folding of the folding laps along the intended transverse fold lines and the bonding of the same takes place, in order finally to the in FIGS. 2, 3 or in Figs. 5, 6 shown packaging to arrive.
