Abstract: A plastics tray, in particular a crate, to be used for objects or merchandise, which is provided with a space bounded by edge parts (6,7) at both sides, said space being used for posi­ tioning a carrier (5) for marks. The space and the carrier (5) extend around the plastics tray.

Description: A plotios troy, in particulor @ @rote, to be used for objects of merchandise. The invention relates to c plastics troy, in particular a crate, to be used for objects or merchandise. Various factories or commercial enterprises nowadcys use trays or crates especially made of a plssticsf which all have distinguishing features as to form and design. Thus, for example, the beverage industry utilizes for each different brand an especially design crate adapted ta a particular brand, contrary to those branches of industry using glass or tinned packing means. This offers the disadvantage that, because of the great variety of crates for, for instance, a number of bottles, they are unnecessarily costly, while return transports of these crates cause additional difficulties, for example, in getting crates with empty bottles back to the proper ploce of delivery. It is the object of the present invention to provide a plastics tray, in particular a crate, of a single standardized model, which can be utilized by different manufacturers, each manufacturer or any other supplier of the tray or crate contents being able to carry his own brand name. This requires special measures to be taken into account already when manufacturing the tray or crate. According to the invention, chis object @@ @@@@@ utilizing plosties troy or ctate orovided @@@@ extending around the tray for positioning u carrier provided with marks or colours, said space being bound by edge parts at both sides of said spoce. Preferably, the carrier is put in place in @ lo@se or partly loose relationship, said carrier also extenaing around the tray. According to a very preferred embodiment the carrier consists of a plastics foil hact shrunk onto the tray The carrier may be formed, f@@ excmple, by plate provided with a label, or alternatively, by c for instance in the form of a band which can be put around the tray or crate for instance by attoching its end to each other using an adhesive. This wrapper may also consist of n light kind of cardboard or paper. However, it is also possible to use a plastic for the mork carrier, as indicated hercin before. The-invention will now be explained by means of an embodiment as shown in the drowings, wherein - Figure 1 represents a perspective view of an embodiment of a tray or crate in accordance with the invention; - Figure 2 is an identical perspective view of a crate as shown in Figure 1 but without the carrier for marks; Figure 3 is @ top view of a looding peile wherein solid and broken likes and @@@ the @@@@@ - Fig. 4 is a vertical cross-sectional, portially lateral view of a port of a trait according to the invention, and -- Fig. S is is a vertical cross-sectlonal view of an end K of a crate of the invention In the embodiment as shown in Figure 1, a crate is provided with partially double-walled side wolls 1 and partially double-walled end walls 2 provided with handle-forming openings 3. Along the upper border areas the side walls 1 and the end walls 2 are provided with recessed portions 4; the manner in which these recessed portions are obtained will be described later on, In this embodiment there is provided around the crate a whopper 5 being formed by a strip of material, for example a light kind of cardboard or paper, which strip has been pulled tightly around the crate, the extremities of the strip being attached to each other for example by means of an adhesive. As is clearly apparent from the drawing, this wrapper forms the carrier for marks, thus making it possible to readily see what kind of merchandise the crate contains. It is also possible to attach, for instance by using an adhesive, -the wrapper 5 to the crate at several points, so that it is placed on the crcte in a loose or partly loose relationship. In the embodiment as shown in Figure 1, all the walls hove a special locotion for positioning the carrier which is in the form of a wrapper 5, the positioning place being formed in that in areas adjocent to the spot reserved for the mark carrier there are provided portions 6 and 7 which are raised with respect to the edges of the carrier. On occount of the raised portions 6 and 7, the wrapper 5 cannot slide or be slid off the crate, since near the raised portion 7 the wall extends outwardly with respect to the wrapper 5, there being at the raise@ portion. @@ obutting edge for protecting the wrapper. The relcec 6 and 7 are also present at the corners of the crate, so tray they merge from one wall, for example from the wall 2, into the other wall 1. If desired, this wrapper 5 con removed, for instance by using a knife. In a preferred embodiment the libel 5 extending around the tray hcs been heat shrunk onto the plastics foil comprising the marks. So as to clearly show the spoce 8 for positioning the shown in Figure 1, the crate of Figure 1 has been drown @@ Figure 2 without the carr@er The raised portions 6 and 7 in the side walls 1 and the d walls 2 can be clearly seen therein, so that the space 8 for positioning the carrier is clearly determined by the raised portions 6 and 7. As is apparent for instance from the loading diagram of the loading pallet 19 shown in Figure 3, it is most desirable that a carrier for marks be put in place in a protective manner. In said Figure, broken lines 10 indicate the arrange ment of adjoining crates. Solid lines 11 indicate a second layer of crates on the pallet 19. The spaces for pusitioning the carriers being protected cs a result of the raiscd portions, th carriers or labels will not get damoged, for instance when sliding against each other due to the shaking on a truck. Upon the layer indicated by the slid lines another layer of crates can be placed in accordance with pattern indicated by the broken lines 10. The @@ternatin arrangements in the positioning of the creter on the looding pallet can be continued until the maximum numb@@ of loyers has been reaches the carriers b@@@g well protected et all times. The embodiments of crates generally described hereinbefore are manufactured with the @id of complicated moulds, the material to be used being a thermoplastics mcterial, such as on impact-resistant polyethylene of polypropylene. The cross sectional view of Figure 4 shows the complicated manner in which. such a crate is composed, the base is generally. indicated by the reference numeral 12. Along the circumference the base is provided with a number of supports 1.3 disposed at some distance frsm each other. Each interval of spaces between two s.upports. is such that it is adapted to always fittingly receive two parallelly arranged top edges 14 of a crate.. This is necessary in order to obtain the loading diagram as illustrated in Figure 3, so that the crates in o layer are always retained by crates of a layer disposed thereupon or thereunder. In the crosssectional view of Figure 4, an end well is provided with an opening 15, which serves as a handle The reference numeral 18 indicates the inner side of the end wall. Together with the bose 12, the end wall 18 and the side wall 19, an interior is formed which consists of vertical partitions 20 interconnected by means of connecting members 21 at the upper part. In certain places said connecting members 21 extend in. the form of ribs 22 along the walls in upward direction, so as to reinforce the walls. In the vitinity of the upper edge 1.4 the inner end wall 18 has protruding flange 23 enclosing, in coni@nction@ a reinforcing border 17 and a vertical rib 24, a rece@@@d area. Thus, a rigidupper border is obtoi-ned-, as is shown for example in Figure 1. The remaining part of the end woll 18 as well as that of a side wall 19 possesses an outer part A.,r located at some distance from the inner part 1.8. By @ay f ribs 26, the part 25 in turn is connected to the part 18. The ribs 26ore disposed at regular intervals along the circumference of the crate. It is obvious thot a relatively complicated mould construction is needed for the manufacture of the inner part 18 of the end wail with the ribs 13, 17, 76 and the outer port 25 However, this construction ran be profitably utilized to provide a place for positioning ç corrier, by making a step 27 in the core between the wall sections 18 and 25 and the ribs 26. In a similar way it is possible to so provide on the outside a recessed portion 28 so as to obtain a positioning ploce 29 in the wall section 25. At the rib 16 it is possible to provide likewise a recessed portion indicoted by the reference numeral 30. To this end it is possible to use ports of the mould which, with respect to the closing direction of the moulds, are movable sideways with a view to forming the recess at the rib 24 and the opening 15. Figure 5 shows a part of a cross-section through a double walled crate comprising walls 36 and 37. The crate comprises a grip 33 and a space 31 extending around the crate. This space ed is bound by edges 32 and 34. Advantageously a ridge 38 may be present in order to hold the wrapper 5 extending around the tray. For an @asy removal of the wrapper the inner wall 37 may be provided with apertures 39.
