Description

Plastic bottle crate The invention relates to a bottle crate Made of plastic with parallel side and end walls, which are in the area of the box corners Form supports for lifting loads in a stack.

Bottle crates of this type are usually designed so that the The side and end walls at the box corners merge into one another with a rounding, the radius of which corresponds approximately to the radius of a bottle standing in a box corner. Since bottle crates are stacked in high stacks in practice, wear the lower boxes the weight of the stacked boxes. Usually, therefore one or more vertical stiffening ribs are provided in the area of the box corners, which together with the associated wall parts form strong corner supports. Additional horizontal ribs provide the necessary strength under loads in others Directions. The attachment of ribs takes into account the general requirement the desired strength with possible. Very little material expenditure and thus low To achieve weight. In addition, the plastic material commonly used is proportionate expensive and represents a significant cost factor in the manufacture of bottle crates represent.

For the practical usability of bottle crates is still their space requirements are important. It plays here because of the limited storage and transport space In particular, the footprint required for each box is important because the Crate height essentially by the height of the bottles intended for the crate is given. The footprint that each box in a field of as narrow as possible adjacent boxes required is a rectangle or square whose dimensions in addition to the number and size of the bottles to be placed in a crate on the strength the outer walls and the height of the outwardly protruding ribs depend. The number and size of the bottles is given, and the thickness of the outer walls and the height the ribs may have a certain dimension with regard to the required strength not fall below.

The invention is based on the knowledge that a better or at least just as good utilization of the base area can be achieved if those in the rectangular or square base through the rounded box corners free area for the construction is used.

The invention is based on a bottle crate of the introduction mentioned type and recommends that the side walls in the area of the box corners Flat corner surfaces extending over the height of the box form that up into the one defined by the rectangular or square base of the box Corner.

The required stiffening of the box can then by the up side wall reaching into the corner can be reached itself. In addition, there is the Possibility in the free space between the box corner and the neighboring bottle to attach internal stiffeners that do not appear to the outside and therefore neither impair the appearance of the box nor make it difficult to handle. Stacking boxes that are lying flat is made easier because the boxes have defined levels Surfaces, namely the corner surfaces, instead of in contact with ribbed side walls stand. The stackability of horizontal boxes is ideal for storing wine bottles important. In addition, with this type of stacking, the contents of all boxes can be sold be made accessible at the same time.

The invention recommends in its further training that the corner surfaces offset from the side walls to the outside up to the level of stiffening ribs which are arranged between the corner surfaces. It then becomes the entire, in the space available at the corners of the floor space is used. The transition from the side wall in the outwardly offset corner surface causes additional stiffening. The corner surfaces remain the contact surfaces when standing next to each other or horizontally stacked boxes.

Bottle crates are commonly used in bottling plants and breweries today loaded and transported by machine. To do this, one uses clamping jaws, the two or Detect three or more bottle crates standing next to each other at the same time and lift.

About slipping of the adjacent surfaces of two boxes or to prevent the middle box from slipping through in the case of three boxes, it is known, on the outer walls of a box from the middle to one side to provide two horizontal ribs and one horizontal rib on the other side. If the ribs are arranged diagonally symmetrically on opposite walls, they can penetrate into one another and prevent them from standing next to one another a slip. It is already known for the same purpose in the case of bottle crates with a grip edge made of a U-shaped profile within the profile a cam or the like to be provided, in the case of boxes standing next to one another in the handle edge of the neighboring box penetrates. In both cases, the locking parts protrude but disturbing far to the outside. In addition, the correct function is only then ensured when the boxes standing next to each other are at the same height.

This requirement is not always met with uneven parking spaces.

A further development of the invention proposes that the corner surfaces after Kind of a rack with horizontally running, in the same way distance arranged, narrow and low webs are provided, which are on the respective diagonally opposite corner surfaces of the box are at the same height, on the other hand, on the adjacent corner surfaces, by half the height of the web spacing from one another are shifted in such a way that the webs are next to each other or laterally one on top of the other Boxes can interlock like teeth. That way you will for sure prevents boxes from slipping through even if boxes are standing next to each other originally not occupy exactly the same altitude. There is always a large number of webs are in engagement with one another at the same time, the webs only need a lot to be low. A kind of corrugation is sufficient.

It should be noted that the corner surfaces are a prerequisite for the realization of this advantageous feature. With the well-known bottle crates there are no flat surfaces available in the corners or in any other area, which lie next to each other when the boxes are standing next to each other or stacked horizontally.

A further development of the invention provides that at the top of the box and at a distance below that, two horizontal stiffening ribs extending into the corner surfaces are present, which one with the associated wall part in a well-known manner Gripfringem'1t Form a U-profile and limit a handle opening at the top. There is also the possibility that the stiffening rib on the upper edge of the box is led to the box corner and in the area of the corner surfaces from these to Box interior protrudes. Seen from above on the box is then one over the The entire side wall has a smooth, continuous surface, which makes it easier to stack more Boxes relieved.

The invention provides in its further development that the box bottom in a manner known per se within a floor frame parallel to the side and end walls of the box extending, intersecting bars, and that at least the one that is closest to the corner surfaces and that runs at right angles to them Rod has downwardly open U-profile. The U-profile bars not only increase that Load-bearing capacity of the box with a pressure acting on the corner surfaces, but also prevent a change in shape due to their greater flexural strength of the box, for stacking horizontal boxes with a framework for receiving and Separation of the bottles, it is recommended that the framework walls in per se known In their upper area to occupy projections pointing into the interior of each compartment, which cause the bottles to be slightly inclined. This prevents the bottles fall out of a lying box.

For the formation of the end walls of the bottle crate, one recommends Development of the invention that the end walls laterally by over the box height extending outer ribs are limited, which represent part of the corner surfaces. In addition, further ribs can be provided, for example the end walls divide into individual fields.

On the other hand, it is often advantageous if the end walls after a development of the invention in the same way as the side walls are and converge with these in the box essentially without rounding. This means that corner surfaces are also present on the end walls, which with the Corner surfaces on the side walls form a stiff angle profile. Such a box speaks because of its symmetrical shape and continuous vertical surfaces also externally. All of the advantages and options outlined above with regard to the Side walls also apply to the end walls. In addition, the proportionate large cavity in the area of the corners used to attach effective stiffeners will. One or more horizontal stiffening ribs can be placed in the box corners be provided, which merge into the side and end walls of the box and outside the vertical projection of the base of a bottle standing in the corner of the box lie. At the top of the box there can be short diagonal ribs bridging the box corners be arranged leading to a stiffening of the box under loads run in a diagonal direction. Finally, there is another recommendation the invention the possibility that in the box corners one is about the box height extending wall is arranged in the side and end walls of the box passes over and this is supplemented to form a hollow profile. Then particularly stiff ones arise and load-bearing corner supports.

The invention is described in more detail below with reference to the drawings. 1 shows the side view of a first exemplary embodiment with a sectional illustration in the left part according to the section line I in Fig. 2; Fig. 2 in the left part is a sectional view corresponding to the section line II in Fig. 1 and in the right part a bottom view of the embodiment; Fig. 3 in the right part the front view of the embodiment 1 and 2 and in the left part a sectional view corresponding to the cutting line III-III in Fig. 1; Fig. 4 is an enlarged partial view of those provided with bars Corner surfaces of two adjacent boxes; 5 shows a modification of the corner area in the upper left part of FIG. 2; Fig. 6 in the right part is a side view and in the left part a sectional view of a second embodiment the invention ; 7 in the left part shows a sectional illustration of the exemplary embodiment 6 and in the right part a view from the ground; Fig. 8 right the end view and on the left a sectional view of the exemplary embodiment according to FIGS. 6 and 7; Fig. 9 shows the top view of the box corner in the upper left part of FIG. 7.

The bottle crate according to FIGS. 1 to 3 is parallel to each other running side walls 1 and end walls 2. In the area of the box corners are the Sidewalls offset outward with the mediation of an inclined surface 3 and form flat corner surfaces 4, which lead into the corner of the box base and essentially run through the entire height of the box. The end walls 2 are vertical Ribs 5 bounded, which are also part of the. Corner surfaces 4 are. Additional vertical and horizontal stiffening ribs 6 divide the end walls into individual fields.

There are handle openings in both the side walls 1 and the end walls 2 7 attached, the forehead of the ribs .6 and on the Seiton winds of ribs 8 can be bordered. In addition to stiffening, ribs B or 8 an enlargement available Grip surface upwards is the Box bounded by a circumferential horizontal outer rib 9, which in the corner surfaces 4 opens and in the area of which protrudes into the box interior. Above the handle openings 7 forms the rib 9 together with that running on the upper edge of the handle openings Rib 6 and 8, respectively, have a U-shaped profile. The side and end walls are on the bottom bounded by a likewise circumferential rib 10, which in turn in the corner surfaces 4 joins.

The box interior is through intersecting half-timbered walls 11 in total 24 bottle compartments divided. The half-timbered walls 11 point in the area of their crossing points in a known manner on the bottom cutouts, which lead to a saving of material and facilitate the drainage of washing and condensation water. The upper edge of the Truss walls 11 are also designed in a known manner zigzag to To facilitate the setting of the bottles, the bottom of the box is supported by a frame 12 bordered and consists of parallel to the side and end walls Rods 13> which intersect at right angles approximately below the middle of each compartment.

The rods 13 are approximately rectangular in cross section. Apart from are the two adjacent to the end faces 2 and running parallel au diea.n Stibe 14 with a downwardly open U? Roffl sterieh * a This allows a higher Buckling strength with an aut-die'Eckflächen 4 acting load reach. In addition, the higher flexural rigidity of the rods 14 prevents premature parallelogram-like deformation of the box under load. If necessary, can also the rods 13 or some of them can be equipped with a U-profile.

On each corner area 4 is a field of horizontally running, at the same distance mordered, narrow and low webs 15 are provided. the Web of the diagonally opposite corner surfaces 4 take the same Altitude a. The webs of adjacent corner surfaces, on the other hand, are half the web spacing shifted in height against each other With two boxes standing next to each other, their Corner surfaces 4 rest against one another, the webs 15 of both boxes can therefore enter the spaces penetrate between the webs of the other box in the same way as when interlocking of two racks. When lifting, for example, three adjacent ones Boxes with the help of clamping jaws prevent the bars from engaging with one another 15 certainly a slipping through of the middle box. A corresponding shift protection is achieved when stacking boxes that are lying flat.

Since a very large number of webs 15 are in engagement with one another, can the web height can be very small. In the practical handling of the boxes, disruptive, So there are no parts that protrude far outwards available. The web height can for example be 1 mm with a web width of 2 mm and a distance of 2.5 mm. In Fig. 4 it is shown enlarged how the webs 15 interlock, when the two parts shown are pushed together by two bottle crates. The bar profile shown is only an example.

In each of the box corners there is a cavity that is used for setting a bottle 16, shown only schematically, is not required for stiffening a horizontal web 17 is provided which connects the end wall 2 with the inclined surface 3 and the corner surface 4 connects.

If necessary, several webs 17 in different Alternatively, according to FIG. 5, a hollow profile can also be used Realize at the corners, if the front and side wall through one over the box height extending wall 18 are connected.

The exemplary embodiment according to FIGS. 6 to 9 is correct many features with the embodiment described above. Same or similar parts therefore have the same reference numerals.

The bottle crate according to FIGS. 6 to 9 is proportionate to 12 large bottles intended. Therefore, the dimensions are different from those of the first Embodiment. The end walls are in the present case With the exception of the different dimensions, it is designed in exactly the same way as the side walls 1. The end walls are also offset outwards in the area of the box corners and have flat corner surfaces 4a, which with the corner surfaces 4 of the side walls in substantially collide without rounding. Only the corner surfaces 4 are with webs 15 provided. If necessary, such webs can easily but also on the Attach corner surfaces 4a.

Both the end walls 2 and the side walls 1 have in the lower Area of the box has openings 19 through which the bottle labels are visible and which provide better air circulation, especially when boxes are stacked horizontally enable.

To save material, there is a rib that runs around the bottom of the box in the area of the box corners openings 20. According to FIG short diagonal ribs 21 are arranged, which merge into the rib 9 surrounding there and bring about a diagonal stiffening of the box, the framework walls 11 have in its upper area short projections 22, which when stacked horizontally Guide the crates to incline the stored bottles. Appropriately run the Projections 22 upwards in an inclined surface to allow the setting of the bottles not to hinder
