Norj a-Norge (NO) (72) Per Sigmund Strömberg, Lilleström, Norway-Norge (NO) (7 * +) Oy Jalo Ant-Wuorinen Ab (5 * 0 Plastic box, especially for bottles - Plastl & da, i synnerhet för flaskor

The invention relates to a plastic box, in particular for bottles, in which the four corners of the rectangular bottom of the box are formed with hollow profile bars perpendicular to the bottom surface, which are connected in one piece by transverse beams arranged at the top and bottom of the box parallel to the open side and end walls.

However, in the known plastic box on which the invention is based, the corners are reinforced in such a way that they are formed as hollow profile columns and the cross-beams forming the upper edge of the box and the bottom of the box are formed in one piece with the hollow profile columns. The cross beam is a wall with stiffening flanges parallel to the bottom of the box. The cavity of the corner profiles can be further stiffened by reinforcing members. However, the crossbeams around the large side and end openings are made relatively weak, so that they can bend sideways, especially when stacking several boxes on top of each other, which is why larger quantities of such boxes cannot be stacked without further ado.

It is further known to form the side walls of the transport platforms into a U-shaped profile, the open side of which is turned towards the underside of the transport platform. The branches of the U-profile are reinforced separately by forming flanges and using iron reinforcements. When the side walls of this transport platform are not provided with openings but the walls are, on the contrary, closed, they do not have such strength problems as plastic boxes for bottles.

This also applies to another known transport container in which the crossbeams and corner posts are formed by individual metal profiles attached to connecting pieces which remain attached to the metal profiles. The end and side walls consist of plates with edges that fit the U-profile of the crossbeams and corner posts. The inner and outer walls form smooth surfaces, but due to the considerable manufacturing steps and the assembly of many different parts, the transport container is simply not suitable as one-piece plastic boxes for bottles, which box has large end and side openings for removing bottles.

Now that. it is an object of the invention to further develop such a box so that, with minimal material consumption, the rigidity of the boxes is correspondingly improved so that the crossbeams at the top of the boxes do not bend outwards when the boxes are stacked due to high weight loading.

According to the invention, this is solved in that the cross beams consist of a U-profile directed towards the bottom of the box, with internal stiffening flanges, the branches of which form smooth surfaces with the inner and outer wall walls of the hollow profile columns.

Thus, the crossbeams are sufficiently stiffened so that no bending occurs during stacking and the end and side openings can be shaped large enough. In addition, profiling allows for a significant reduction in the weight of the box. In addition, the boxes are easier to clean. Both end and side walls can be provided with large openings through which the contents of the box can be removed laterally.

According to one embodiment, the inner surfaces of the crossbeams and the hollow profile columns arranged at the bottom of the box are shaped to be slightly inclined towards the central part of the box. This makes it easier to stack the boxes and prevents the stacking edges from getting stuck.

According to a further feature of the invention, the open sides of the U-profile are provided with gripping edges, which facilitates the handling of the boxes.

Other features of the invention will become apparent from the following description and claims.

3 60840 offers considerable possibilities to place one or more stacks of boxes freely on the floor of the trade. Since the cross beam in its very top position slides behind the wall plates of the U-profile beams and is not visible from the outside of the box, it also does not prevent the goods from being taken out of the box through the opening.

According to one, but by no means insignificant, feature of the invention, all the outer surfaces of the box are flat. In addition, the box wall is closed at the top, the top surface corners are provided with holes for ventilation, the box wall base is open and the extension of the inner plate at the bottom of the wall forms a stabilizing edge. Alternatively, the box wall at the bottom may be closed so that the bottom surface corners are provided with holes for ventilation, the top of the box wall is open, the extension of the inner wall at the top of the wall forms a stabilizing edge, and this stabilizing ring causes the boxes to adhere to each other. are stacked on top of each other.

These features are important when cleaning boxes, as a box with flat walls is clearly much more hygienic in use than a box with all kinds of protrusions, such as in previously known boxes. Because the box is provided with holes for ventilation, efficient cleaning is also possible in the space between the two partitions by draining the water between the walls. In addition, holes may be appropriate, for example, in the manufacture of a box.

When stacking these types of boxes, relatively high stability is required. This can be solved primarily by the fact that the vertical corners outside the box are rectangular, while the corresponding inner corners are rounded and that the upper (possibly lower) inner edge of the box is slightly inclined downwards and inwards.

The purpose of the sloping edge is to make it easier to stack the boxes and to prevent the stabilizing edges of the boxes from wedging.

According to another embodiment of the invention, this cross latch comprises two parallel plates, between which members are arranged, which act as combined spacer and connecting members.

This cross latch is further provided with a guide edge which can slide in the sliding groove of the cross latch. The cross latch is further provided with a suitable finger grip.

Other features of the invention will become apparent from the following description and claims.

^ 60840

The invention will be described in more detail with reference to the accompanying drawing, in which: Figure 1 shows an embodiment of a box according to the invention, Figure 2 shows a lower or possibly upper corner edge according to the invention, Figure 2a shows an edge in section and Figure 2b in profile.

Fig. 3 shows a part of the side opening of a box according to the invention, Fig. 4 an upper or lower corner edge according to the invention, Fig. 5 a bottom view of a box, and Fig. 6 a bottom view of a box with regular depressions.

Fig. 7 shows another structure of a box according to the invention, Fig. Ö a side of a box without an outlet with a cross latch, Fig. 9 a section through the box part and the cross latch, and Fig. 10 the slope of the sliding groove and the lower part of the sliding groove.

Fig. 11 shows two superimposed boxes, the top box being provided with a bottom with intermediate edges, and Fig. 12 a section through the bottom according to Fig. 11.

Figures 13 and 14 show a section of the wall of the box on the side of the box shown in Figure β, which may be provided with a gripping member, and Figures 15 and 16 show a member for closing the opening located between the wall plates.

In Fig. 1, 1 means the corner beam of the box, 2 the outlet openings, 4 3 drawers with vertical inner and outer corners. The number 5 means a cross latch which slides in a sliding groove 6, in which two cross latches 5 are shown in their uppermost invisible position and two latches in the intermediate position, and in which one or more latch devices 7 are placed in the sliding grooves. a stabilizing edge located at the bottom of the box, but as will be apparent from the above, the stabilizing edge may also be located at the top of the box.The number 9 denotes the cross-sections of the side opening and a reinforced mesh structure 10 is placed on the bottom on which the objects can be placed. holes 11 are drilled in the corners for ventilation, the inner edge of the wall extending upwards (possibly at the bottom) by a part 12 downwards and inwards.

Figure 2a shows the corner structure of the bottom (possibly the top) of the wall, where 10 denotes the net and 13 the stiffening and spacer members in the walls. Fig. 2b shows the same as Fig. 2a but with the difference that the net 10 is not shown, in which case the structure of the stabilizing ring edge Ö is clearly visible.

Because the walls of the box are double, it is possible to equip the tops of the top beams with notches without reducing the stiffness of the box. These notches communicate with the stiffened portion of the T-shaped profile of the net 10 when the boxes are stacked on top of each other, which has not previously been possible due to the poor structure of the crossbeams. Thus, the invention has made it possible to stack the boxes much more firmly than has hitherto been possible.

Fig. 3 shows an outlet opening in the wall surface, which clearly shows how the stiffeners 13 and the spacer members 14 are arranged between the wall-memory plates 14.

Figure 4 shows the upper corner (possibly the bottom corner) of the wall, in which the inner edge is inclined and the corners are provided with holes.

Figures 5 and 6 show two other embodiments of the bottom of a box according to the invention. In Figure 5, the grids of the grid are parallel to the outer surfaces of the box. Intermediate and stiffening members 13 are arranged in the extension of each profile 10. · It is clear that the members 13 do not have to be placed as shown, but can be placed between the wall plates 14 to the extent of the gear plate, regardless of the location of the T-profiles of the net 10. The beam stiffening this T-profile is marked with the number 10 ’.

Figure 6 shows a different type of base structure, in which the inner walls of the box are provided with regularly outward, perpendicular roundings 22, which roundings are evenly spaced along the entire inner surface of the box. The base in Fig. 6 is provided with a torn base plate 21 with a stiffening column grid 10 "vertically against the base. Instead of a perforated base plate, for example, the net shown in Figs.

Figure 11 shows another structure of a box base, comprising for example a perforated plate 21 and provided with spacers 10 '". The purpose of these spacers lo'" is both to separate the goods placed in the box from each other while providing the necessary stiffening of the box base. They thus act as stiffening columns as the columns 10 'and 10' in Figures 5 and 6. Instead of a perforated plate, the base can be equipped with a suitable lattice structure 6 60840.

The box is shown in Figure 6 from below. Although the box in this case is provided with a wavy stabilizing edge, i.e. with the extension of the inner surface of the box 6, it is self-evident that this stabilizing edge can be made similar to that shown in Figures 2b and 5, whereby only that part of the inner wall of the box which is located above the bottom becomes corrugated. Thanks to the corrugation according to Figure 6, the volume of the box can be utilized much more efficiently without being at the expense of the strength of the box.

Fig. 7 shows another embodiment of the outlet opening and the cross latch compared to the structure according to Fig. 1. The opening 2 is provided with sloping corners 15, which increases the rigidity of the box, and the wall thickness of the box is smaller at the upper part 16 of the wall than at the lower end, as shown in Fig. 10. Fig. 7 shows a section I how the stabilizing edge β adheres behind the top 16 of the wall.

5 'means a strip in the cross latch 5, which strip, when in its lower position, goes into a corresponding opening 23 in the lower part of the sliding groove 6, as shown in section II of Fig. 10. The left side of the opening 2 in Figure 7 shows the cross latch in the latch position, while its right side shows the latch in the upper position, where the goods can easily be taken out of the opening. 5 "refers to a suitable handle in a cross latch by means of which it can be moved across the opening. Figure 6 shows one side of a box according to the invention provided with an opening 2 'which is used only when moving the box by gripping the edge 17. Figure 9 shows another structure of the cross latch. consists of two plates, between which are connected intermediate spacer and connecting members 5 '"· The second plate is provided with a guide edge 6' which slides in a sliding groove 6. The lower end 23 of the sliding groove may have holes for guiding the cross latch when it is in its lower position. The sliding edge of the latch is substantially parallel to the outer edge of the box. The inner edge of the box is slightly inclined inwards as indicated by the angle α in Fig. 10, whereby the part 25 remains inside the surface of the box. This part corresponds to the material thickness of the cross latch plates.

Fig. 11 shows a box which, in the same way as shown in Fig. 1, is provided with corner posts 1, rounded as indicated in point 4. The crossbeams 26 and 27 have double walls as in the other walls of the box, as shown in the figures.
