Description

[0001] The invention concerns a blank for a box, an assembly of such blank and a tape for sealing the box, and a box formed from such blank or such assemblyBACKGROUND OF THE INVENTION

[0002] The invention relates to a blank for a box, an assembly of such blank and a tape for sealing the box, said tape having a breadth B, said blank having a thickness T and a rectangular bottom panel, a first rectangular side panel joined to a first side of the rectangular bottom panel, a second rectangular side panel joined to a second side of the rectangular bottom panel opposite the first side thereof, a first rectangular end panel joined to a first end of the bottom panel, a second rectangular end panel joined to a second end of the bottom panel opposite the first end of the rectangular bottom panel, a first rectangular corner panel joined to a first side of the first end panel, a second rectangular corner panel joined to a second side of the first end panel opposite the first side thereof, a third rectangular corner panel joined to a first side of the second end panel, a fourth rectangular corner panel joined to a second side of the second end panel opposite the first side thereof, a rectangular top panel joined to the first the end panel such that it is arranged at the side of the first end panel opposite to the side where the bottom panel is joined to the first end panel, a first rectangular top side panel joined to a first side of the top panel, a second rectangular top side panel joined to a second side of the top panel opposite the first side thereof, and a rectangular top end panel joined to the top panel such that it is arranged at the side of the top panel opposite to the side where the first end panel is joined to the top panel. Such a layout of a blank is known as the International fibreboard case code, also called the FEFCO-ESBO code 11th Edition, 2007, number 0410 M / A. From such a blank a box for packaging items can be erected which box is sealed by attaching tape over the seam between respective panels or by using glue. According to the FEFCO code 0410 M / A, the width of the side panels is equal to the height of the box, so that the seams will end up at the edges of the box, which complicates e.g. taping, whereas according to GB 1 248 131 A, US 2002 / 134827 A1 or EP 1 136 368 A1, such seams are retracted from edges at a bottom panel of a box.

[0003] Drawbacks of the known assembly and blank are that sealing the box formed out of said known blank by using tape is relatively difficult to perform and in some cases during transport of the box the tape tears resulting in the unwanted opening of the erected box. A further drawback of the known blank is that it is relatively complicated to use for automated packaging of articles. DE 20 2005 002860 U1 discloses blank for a box, having a rectangular bottom panel, a first rectangular side panel joined to a first side of the rectangular bottom panel, a second rectangular side panel joined to a second side of the rectangular bottom panel opposite the first side thereof, a first rectangular end panel joined to a first end of the bottom panel, a second rectangular end panel joined to a second end of the bottom panel opposite the first end of the rectangular bottom panel and having a free end side opposite the second end of the bottom panel, a first rectangular corner panel joined to a first side of the first end panel, a second rectangular corner panel joined to a second side of the first end panel opposite the first side thereof, a third rectangular corner panel joined to a first side of the second end panel, a fourth rectangular corner panel joined to a second side of the second end panel opposite the first side thereof, a rectangular top panel joined to the first end panel such that it is arranged at the side of the first end panel opposite to the side where the bottom panel is joined to the first end panel, a first rectangular top side panel joined to a first side of the top panel, a second rectangular top side panel joined to a second side of the top panel opposite the first side thereof, a rectangular top end panel joined to the top panel such that it is arranged at the side of the top panel opposite to the side where the first end panel is joined to the top panel.SUMMARY OF THE INVENTION

[0004] It is amongst other things an object of the invention to provide an alternative blank for a box as well as an assembly of a blank for a box and a tape. It is a further object of the invention to provide an assembly of a blank for a box and a tape from which a box can be formed which can relatively easily be sealed by means of the tape. It is a further object of the invention to provide an assembly of a blank for a box and a tape from which a box can be formed which when sealed by means of the tape can be transported with a relative low risk of unwanted opening. Another object of the invention is to provide a blank for a box from which relatively easily a box can be folded around articles to be packaged in an automated way.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0009] Figs. 1A to 1E are used to generally describe an embodiment of an assembly 30 according to the invention of a tape 74 and a blank 40 is shown schematically in views in perspective of various stages of folding a box from the blank 40. The tape 74 has a breadth B and is in this embodiment integrally provided with tear means, such as a tear strip 75. In other embodiments (not shown) the tape may alternatively be free from tear means. The blank 40 has a thickness T, and in this embodiment is manufactured from card board.

[0010] The blank 40 (see Fig. 1A) has a rectangular bottom panel 41, rectangular first and second side panels 42, 43, respectively, and rectangular first and second end panels 44, 45, respectively, joined to the bottom panel 41. Rectangular first and second corner panels 46, 48, respectively, are joined to the first end panel 44. Furthermore, rectangular third and fourth corner panels 47, 49, respectively, are joined to the second end panel 45. A rectangular top panel 50 is joined to the first end panel 44, such that it is positioned at the side of the first end panel 44 opposite to the side where the bottom panel 41 is joined to the first end panel. The blank 40 furthermore comprises rectangular first and second top side panels 51, 52, respectively, joined to the top panel 50, a rectangular top end panel 53 joined to the top panel 50 and, optional, rectangular first and second top corner panels 54, 55, respectively joined to the top end panel 53.

[0011] Panels which are directly joining each other are joined by means of folding lines, such as the first end panel 44 and the top panel 50 which are joined by lid folding line 60. Each folding line can consist of a single, double or triple score lines. Please note that for sake of clarity only the lid folding line has been provided with a reference number. Neighbouring panels which are indirectly joined to each other, such as first side panel 42 and second corner panel 48, are spaced by a cut-out 56. The cut-outs 56 between the respective corner panels and the adjoining side panels each have a length G (measured in the longitudinal direction of the blank 40) which in the shown embodiments amounts to T [shown in the figures is appr. G=T, although G≈2T would be preferred], but which in other embodiments can have any value up to 4T, thus a length which is sufficient for allowing a correct folding of the panels with respect to one another. The dimensions of the respective panels will be further discussed with reference to the embodiments shown in Figures 5 and 6.

[0012] In Figures 1A - 1F the different stages of folding of the blank 40 is shown in which in Fig. 1B to 1E only the blank 40 is shown for clarity, i.e. the tape is not shown. Figure 1A shows the blank 40 in its flat position. In Figure 1B the corner panels 46, 47, 48, 49 are shown partly folded upwards. Thereafter first the end panels 44, 45 are folded upwards and then the side panels 42, 43 are folded upwards. In this situation, shown in Figure 1C the end panels 44, 45 have been erected. Thereafter the top panel 50 is folded over, and the top corner panels 54, 55 are partly folded downwards as shown in Figure 1D. Next the top end panel 53 and subsequently the top side panels 51, 52 are folded downwards obtaining the custom sized, unsealed box as indicated in Figure 1E. As a result of the dimensions of the panels as will be discussed with reference to Figures 5 and 6 a first seam 81 is formed between the abutting first side panel 42 and first top side panel 51, a second seam 82 is formed by the free edge of the top end panel 53, and a third seam (not visible in Figure 1E) is formed between the abutting second side panel 43 and second top side panel 52. As can be seen in Figure 1E these seams are formed on the external surface of the folded box. These three seams form the, what is called here the box seam, which can be seen as a single seam which extends around the box at a single vertical height from the bottom which is at least equal to ½B, i.e. half the breadth of the tape. This makes the application of the single tape 74 around the box to seal the box, as shown in Figure 1F, easy, and allows for automating the sealing process. Key in the invention is that the width of the side panels (42, 43, 51 and 52) relates to the height of the box, in order to obtain a box that has seams along three exterior sides of the box, at a constant height with respect to the bottom plane of the assembled box, in which said height is such that the ease of closing and opening of the box are improved while the risk of untimely opening is reduced.

[0013] In Figure 2 an alternative embodiment of a blank in accordance with the invention is shown in perspective. With respect to the blank shown in Figure 1A the following dimensions are different: the width of the top side panels 51, 52 is increased with a value D, the width and length of the top corner panels 54, 55 are increased with the value D, and the length of the top end panel 53 is increased with the value D. The other dimensions remain unchanged.

[0014] In Figure 3 a further alternative embodiment of a blank in accordance with the invention is shown in perspective. With respect to the blank shown in Figure 1A the following dimensions are different: the width of the side panels 42, 43 and the width of the corner panels 46, 47, 48, 49 are increased by the value D. The other dimensions remain unchanged.

[0015] After folding the blanks according to Figures 2 and 3 an overlap between respective panels is obtained, however the circumference of these blanks is not rectangular. Please note that this overlap between panels improves the protection of items packaged within the box. Also with the overlap which can be obtained in these alternative embodiments the seam of the box which is to be sealed by the tape, is still positioned at a single distance of at least ½B from the edge of the box. In case the box is sealed by means of glue the overlap between respective panels preferably is at least 1 cm to ensure a proper sealing.

[0016] Figs. 4A to 4D schematically show possible manners of sealing a box 80 with tape 74. In these Figures first end panel 44 is indicated which end panel 44 after folding does not comprise a seam and thus need not necessarily be provided with tape 74, as indicated in Figures 4C and 4D without detriment to the seal of the box. It is thus not necessary to completely surround the box by tape. The arrow in the drawings is indicative of the direction in which the tape is applied, but is not compulsory. In addition for clarity sake the tape has been depicted at a distance from the panels of the box, but it will be clear to a person skilled in the art, that the tape is attached onto the panels.

[0017] In Figs. 5A and 5B a further embodiment of a blank in accordance with the invention is schematically shown in which after folding the side panels about each other. Please note that the Figures 5A and 5B represent one and the same embodiment of a blank (apart from the different use of folding lines, as will be discussed below), but for clarity reasons in Fig. 5A only the length dimensions and in Fig. 5B only the width dimensions are indicated. In Figs. 5C and 5D side views in cross-section and in Fig. 5E a top view in cross section of a box erected from the blank shown in Figs. 5A / B is schematically shown in cross-section. In these Figures 5C to 5E it is indicated that L is the inside length of the box, W is the inside width of the box and H is the inside height of the box. Please note that the length dimensions are measured in longitudinal direction of the blank and the width dimensions are measured in lateral direction of the blank. As before the blank has a thickness T (indicated in Fig. 5C) and comprises a rectangular bottom panel 41. A first rectangular side panel 42 is joined to a first side of the rectangular bottom panel 41 and a second rectangular side panel 43 is joined to a second side of the rectangular bottom panel 41 opposite the first side thereof. A first rectangular end panel 44 is joined to a first end of the bottom panel 41 and a second rectangular end panel 45 is joined to a second end of the bottom panel 41 opposite the first end of the rectangular bottom panel 41. Furthermore a first rectangular corner panel 46 is joined to a first side of the first end panel 44 and a second rectangular corner panel 48 is joined to a second side of the first end panel 44 opposite the first side thereof. Furthermore, a third rectangular corner panel 47 is joined to a first side of the second end panel 45 and a fourth rectangular corner panel 49 is joined to a second side of the second end panel 45 opposite the first side thereof. In addition, a rectangular top panel 50 is joined to the first the end panel 44 such that it is arranged at the side of the first end panel 44 opposite to the side where the bottom panel 41 is joined to the first end panel 44. A first rectangular top side panel 51 is joined to a first side of the top panel 50 and a second rectangular top side panel 52 is joined to a second side of the top panel 50 opposite the first side thereof. Finally, a rectangular top end panel 53 is joined to the top panel 50 such that it is arranged at the side of the top panel 50 opposite to the side where the first end panel 44 is joined to the top panel 50.

[0018] In the shown embodiments the tolerance t has a value equal to the thickness T of the blank, but in dependence of amongst other things the stiffness of the material of the blank the tolerance t can have any value up to 2T, i.e. two times the thickness of the blank.

[0019] As indicated in Figures 5A and 5B the rectangular bottom panel 41 has a length L + 2t and a width W + 4t. The rectangular side panels 42, 43 each have a length of about L + 2t and a width of H1 + t. The rectangular end panels 44, 45 each have a width W + 2t, the first end panel 44 having a length of H + 2t and the second end panel 45 having a length of H + t. The rectangular top panel 50 has a length L + 3t and a width W + 4t. The rectangular top side panels 51, 52 has a length of about L + 3t (meaning that the length can also be slightly smaller) and a width of H2 + t. The rectangular top end panel 53 has a length of H2 + t and a width between W + 2t and W + 4t. The cut-outs between the respective corner panels and the adjoining side panels each have a length G which in the shown embodiments is about T [shown is G≈T, although preferred value is G≈2T], but which length G in other embodiments could have any value up to 4T, thus a length which is sufficient for allowing a correct folding of the panels with respect to one another.

[0020] In embodiments where the dimensions H1 and H2 are equal (H1 = H2) a rectangular blank as shown in Figure 1A is obtained. In embodiments where H1 = H2 = ½H after erecting the box the respective panels abut each other as indicated in Fig. 1E. In embodiments where H1 = H2 = ½H + D, after folding the box an overlap of 2D between panels is created which overlap improves protection of items packaged within the box. In embodiments where either H1 or H2 equals ½H + D, after folding the box an overlap of D between panels is created which overlap improves protection of items packaged within the box. In the embodiments of Figs. 5 the values of H - H1 and / or H - H2 are equal to or greater than 1 cm, preferably 2 cm, most preferably 3 cm. Thus also with an overlap the seam of the box which is to be sealed e.g. by tape or glue, is still positioned at a distance of at least 1 cm from the edge of the box. In all these embodiments L is greater than or equal to ½H.

[0021] In Fig. 5A an embodiment is indicated in which the longitudinal folding lines comprise two parallel score lines which are spaced at a distance t" from each other, which distance in the shown embodiments equals T, but which distance t" in other embodiments could have any value up between T and 3T and in which the lateral folding lines consists of a single score line. In the embodiment shown in Fig. 5B, all the folding lines consist of single score lines, but the longitudinal score lines are offset relative to one another with a distance t‴ as indicated in the Figure, which distance t‴ in the shown embodiments equals T, but in other embodiments could have any value up between T and 3T.

[0022] In Figs. 6A and 6B a further embodiment of a blank in accordance with the invention is schematically shown in which after folding the side panels abut each other. Please note that the Figures 6A and 6B represent one and the same embodiment of a blank (apart from the different use of folding lines, as will be discussed below), but for clarity reasons in Fig. 6A only the length dimensions and in Fig. 6B only the width dimensions are indicated. In Figs. 6C and 6D side views in cross-section and in Fig. 6E a top view in cross-section of a box erected from the blank shown in Figs. 6A / B is schematically shown in cross-section. In these Figures 6C to 6E it is indicated that L is the inside length of the box, W is the inside width of the box and H is the inside height of the box. Please note that the length dimensions are measured in longitudinal direction of the blank and the width dimensions are measured in lateral direction of the blank. As before the blank has a thickness T (indicated in Fig. 6C) and comprises a rectangular bottom panel 41. A first rectangular side panel 42 is joined to a first side of the rectangular bottom panel 41 and a second rectangular side panel 43 is joined to a second side of the rectangular bottom panel 41 opposite the first side thereof. A first rectangular end panel 44 is joined to a first end of the bottom panel 41 and a second rectangular end panel 45 is joined to a second end of the bottom panel 41 opposite the first end of the rectangular bottom panel 41. A first rectangular corner panel 46 is joined to a first side of the first end panel 44 and a second rectangular corner panel 48 is joined to a second side of the first end panel 44 opposite the first side thereof. Furthermore, a third rectangular corner panel 47 is joined to a first side of the second end panel 45 and a fourth rectangular corner panel 49 is joined to a second side of the second end panel 45 opposite the first side thereof. A rectangular top panel 50 is joined to the first the end panel 44 such that it is arranged at the side of the first end panel 44 opposite to the side where the bottom panel 41 is joined to the first end panel 44. A first rectangular top side panel 51 is joined to a first side of the top panel 50 and a second rectangular top side panel 52 is joined to a second side of the top panel 50 opposite the first side thereof. Furthermore, a rectangular top end panel 53 is joined to the top panel 50 such that it is arranged at the side of the top panel 50 opposite to the side where the first end panel 44 is joined to the top panel 50. When compared with the embodiment of the blank shown in Figs. 5 the blank according to Figs. 6 further comprises a first rectangular top corner panel 54 joined to a first side of the top end panel 53 and a second rectangular top corner panel 54 joined to a second side of the top end panel 53 opposite the first side thereof.

[0023] In the embodiment of Figs. 6A to Dthe rectangular bottom panel 41 has a length L + 2t and a width W + 4t. The rectangular side panels 42, 43 each have a length of about L + 2t (meaning that the dimension can also be slightly smaller) and a width of H1 + t. The rectangular end panels 44, 45 each have a width W + 2t. The first end panel 44 has a length of H + 2t, while the second end panel 45 has a length of H + t. The rectangular top panel 50 has a length L + 3t and a width between W + 4t and W + 6t. The rectangular top side panels 51, 52 have a length of about L + 3t (meaning that the dimension can also be slightly smaller) and a width between H2 and H2 + t. The rectangular top end panel 53 has a length of about H2 (meaning that the dimension can also be slightly smaller) and a width between W + 2t and W + 4t. The rectangular top corner panels 54, 55 each have a length of about H2 and a width between H2 and H2 + 2t.

[0024] In particular embodiments of Figs. 6 the dimensions H1 and H2 are equal (H1 = H2) such that a rectangular blank as shown in Figure 1A is obtained. In embodiments where H1 = H2 = ½H after erecting the box the respective panels abut each other as indicated in Fig. 1E. In embodiments where H1 = H2 = ½H + D, after folding the box an overlap of 2D between panels is created which overlap improves protection of items packaged within the box. In embodiments where either H1 or H2 equals ½H + D, after folding the box an overlap of D between panels is created which overlap improves protection of items packaged within the box. In the embodiment of Figs. 6 the values of H - H1 and / or H - H2 are equal to or greater than 2 cm, preferably 3 cm. Thus also with an overlap the seam of the box which is to be sealed, e.g. by tape or glue, is still positioned at a distance of at least 2 cm from the edge of the box. In all these embodiments L is greater than or equal to ½H. This is preferred to make the corner panels 46, 47, 48 and 49, and if present, the top corner panels 54 and 55, fit within the box without requiring additional folds.

[0025] In Fig. 6A an embodiment is indicated in which the longitudinal folding lines comprise two parallel score lines which are spaced at a distance t from each other, and in which the lateral folding lines consists of a single score line. In the embodiment shown in Fig. 6B, all the folding lines consist of single score lines, but the longitudinal score lines are offset relative to one another as indicated in the Figure.
