Abstract

Transport securing arrangement for stackable packaging trays, which can be set up with a base part (2) and side walls (3, 5) to form a rectangular box (1) and are connected in the corner area (4), characterized in that one each in the corner area (4) Overlapping tab (7) is arranged, the overhead part (7a) rising upwards and fixed by a dimension (Z) to form a stacking edge (7 ') and for engagement in recesses (8) in the bottom part (2) of the following Rise (1 ') is provided.

Description

The invention relates to a transport safety arrangement with the preamble features of claim 1 and a corresponding blank for this purpose.

Such transport safety arrangements are in commerce, for example in the discount area in large scale in use, especially in the form of so-called. Stacking lugs. In this case, the individual articles, for example a few dozen cups, are combined in a tray to form a packaging unit and stacked one above the other on a transport pallet. Most corrugated boards are used for this purpose. However, the vertically upstanding stacking lugs are relatively easy to fold and their counter-openings are often troublesome so there is a risk that the stack on the transport pallet becomes unstable. As a result, such stacking lugs are relatively unpopular in trade or picking. In addition, such stacking when cutting certain supernatants, so that much cardboard waste occurs and thus the production is relatively expensive.

Accordingly, the invention has for its object to provide a transport safety arrangement which avoids the disadvantages mentioned above and offers good stackability, especially at low cost.

This object is achieved by a transport safety arrangement according to the features of claim 1. Preferred embodiments are subject of the dependent claims.

Due to the self-centering and the secure locking of aligned in the manner of a flat pyramid stacking edges with corresponding recesses in the bottom part of the following tray high stacking strength is achieved, so that the generally provided pallet height can be exploited. Since the blanks for the crate have a substantially rectangular basic shape, the punching sheet is usable with little waste. In addition, this blank can be erected and connected by machine in a simple manner. The only slightly protruding stacking edge is no risk of buckling and it is a simple, stable stacking or palletizing, possibly also possible with robots. The corner areas of the crates are built stably, without hindering the removal of goods. Overall, a particularly inexpensive production, since only simple blanks are required.

Hereinafter, an embodiment of the transport safety arrangement will be explained and described with reference to the drawing. Hereby show:

1 a transport safety arrangement in side view (center) and in two perspective views (slightly tilted up and down); and

2 a blank for the crate (carrier packaging according 1 ).

In 1 is in the middle a side view of a transport crate 1 shown, which consists essentially of a bottom part 2 with attached side walls 3 exists (see the two related perspective views, slightly tilted up or down). The side walls 3 are here to the approximately cuboid crate 1 Erectable, with the side walls 3 in the corner 4 are connected, in particular by tabs 6 starting from a similarly constructed back or front wall 5 (hereinafter also referred to as sidewall) the side walls 3 embrace. These are preferably integral with the bottom part 2 made of corrugated cardboard (see blank in 2 ). In the 1 , wall pointing down to the left 5 bounded (depending on the customer) an access opening to those in the crate 1 stored goods. For this there is a Umklapplasche 9 provided (see also 2 ).

In the four corners 4 are top grip tabs 7 provided, consisting of an overhead part 7a and a side part 7b consist. The latter becomes the sidewall in each case 3 folded down and fitting in a corner section 3 ' inserted, in particular flush with the side wall 3 glued (namely with the tab 6 ). This results in a positive, stable anchoring of the part 7b and a secure support of the part 7a , this part 7a In this case, it assumes an orientation which increases upward by the angle α, so that a supernatant of the dimension Z (cf. 1 , Center) and thus a stack edge 7 ' that results in corresponding recesses 8th , in particular in the slot shape of an overlying tray 1' intervenes. This dimension Z preferably corresponds to the thickness of the bottom part 2 , In synopsis of the four corner areas 4 with the stack edges rising to the tray interior 7 ' results in imaginary extension preferably a flat pyramid shape, so that stacked crates 1 Center yourself, if necessary with slight sideways movements and thus the stack edges 7 ' and the recesses 8th almost find it yourself. When palletizing thus easy stackability and increased stacking strength is achieved.

In 2 is the bottom part 2 with molded side walls 3 . 5 and tabs 6 represented as a single blank, which thus forms the main part of the package. In addition, the overlap tabs 7 and the flapper 9 as well as per se known Einstecklaschen 9 ' integrally formed. The latter will be separated from the flapper 9 in locking slots 9 '' at the tabs 6 plugged in. Due to the compact shape of the blank results in a significant cost reduction in the production and at the same time a high stability. Preference is given to the creases or fold lines shown by dashed lines to delimit the side walls 3 and 5 As well as the adjacent components while passing through the corrugator (with punching the recesses 8th etc.), so that there is a further cost reduction. The tabs 6 become inside to the bottom part 2 folded out and the side walls 3 and 5 to the climb 1 erected, and then usually glued by machine (see. 1 ) or otherwise connected. Through the flapper 9 is side or front wall 5 then double-layered and therefore stable and without open cut edges, if desired by the customer.

As mentioned, the four corner areas have 4 a basically same structure, as indicated by the same reference numerals. In particular, the overhead part extends 7a from every corner area 4 starting inwards towards the middle of the crate and rising upwards so that there is a stacking edge 7 ' yields and thus a total of a pyramid shape with a shallow pitch angle α of about 10 °. The stacking edge thus formed 7 ' must not be straightforward, but z. B. also be slightly curved to the recesses 8th intervene and so the stacked trays or crates 1 . 1' etc. to "lock". The stack edge 7 ' can be even more pronounced when the part 7a an incision 7c in the direction y of the blank (here only at the right, upper handle tab 7 shown. This results in a particularly high stability and robustness of the transport safety arrangement.
