Container for the transport of live poultry

Abstract: A method for filling a container (100) with live poultry, said container (100) comprising compartments (I, II, III, IV, V), one on top of the other. Prior to the filling of a compartment (I, II, III, IV, V) with poultry, the bottom face (30, 40, 50, 60) of the compartment (II, III, IV, V) lying above it, together with the side face (31, 41, 51, 61) thereof, is moved away. Said side face (31, 41, 51, 61) is lying at the filling side of the container (100). The container (100) is constructed in such a way that the poultry will meet no obstacles at the filling side above the compartment to be filled. Moving away said bottom and side faces may be performed by sliding them away sideways or by flapping them up.

Description: The invention relates to a container for live poultry, said container being divided into a number of compartments lying one on top of the other, the compartments comprising a bottom wall, a top wall and four side walls, the bottom wall of a compartment, with the exception of the bottom compartment, forming the top wall of a compartment lying below it, and in which container at least part of the bottom wall of a compartment together with a corresponding side wall, being part of the side wall of the container, is fully or partially movable in such a way that said corresponding side wall moves into the compartment, the container having a filling side from which all compartments of the container can be filled. For the transportation of live poultry, for example chickens, from breeding farm to slaughterhouse containers specially equipped for this purpose are used. These containers have been made suitable for transportation by lorry and are provided with means for moving the container itself, for example by forklift truck. These containers have to be constructed in such a way that they can be filled, transported and emptied quickly and efficiently. It is known per se that these containers are divided into compartments which are high enough for the poultry to be able to stand in them, and are long and wide enough to accommodate a plurality of birds. Such a container is described in ES-U-1 006 405. In this container the bottom/top walls of the compartments consist of elongated elements which are hingedly connected to each other. The side wall of a compartment at the filling side of the container can be pivoted into the compartment, after which the bottom/top wall elements can be rolled up into the container for providing access to a lower compartment. The object of the invention is to provide a container which can be filled easily. This container, having compartments of which at least part of the bottom wall of a compartment is movable together with a corresponding side wall, is characterized in that said at least part of the bottom wall of a compartment together with a corresponding side wall is slidable essentially in the plane of the bottom wall. The container is preferably designed in such a way that the container wall is free of obstacles at the filling side above the compartment to be filled. Advantageous embodiments of the container are described further in Claims 2 and 3. During filling of a container according to the invention with poultry, first of all, the bottom wall is moved together with the side wall of all compartments, apart from the bottom one, fully or partially sideways The top wall of the container may also be moved fully or partially. The bottom compartment is then filled with poultry from the container filling side, from a height which corresponds essentially to the height of the side wall. In this method the birds do not meet with any obstacles and fall down over only one compartment height. When the bottom compartment is full, the bottom wall together with the side wall of the compartment lying above it is then returned to the initial position. This second compartment is again filled with poultry from the container filling side, and here again the birds cannot meet with any obstacles and again fall down over only one compartment height. The remaining compartments are filled in the same way, the top wall of the top compartment being closed when it is full. It will be clear that the method described with the container described is particularly efficient, causes little stress among the birds, and minimizes the risk of injuries. When the container is emptied in the usual manner, namely by placing the container at an angle, following which the birds leave the container through a side wall, a side wall of each compartment is, for example, hingedly connected to the bottom wall, not necessarily the same as the above mentioned side wall. The invention is explained with reference to the drawings, in which: Fig. 1 schematically shows a perspective view of a container according to the present invention; Figs. 2a and 2b schematically show an exploded side view and front view respectively of a preferred embodiment of a container according to the invention; Figs. 3a to 3f show the different phases of filling the container according to Figs. 2a and 2b; Fig. 4a again in side view and schematically shows the layout according to Figs. 2a and 2b; Fig. 4b shows a variant thereof; and Fig. 5 schematically shows a third embodiment. The same reference numbers in the different figures relate to parts of the same type and having the same function. Fig. 1 schematically shows the layout of a rectangular container 100 according to the present invention. Hidden lines are indicated by a dashed line. The base of the container is formed by a frame 200, indicated by a thick line, and made up of ribs 1-2, 2-3, 3-4, 1-4, 1-5, 2-6, 3-7, 4-8, 5-6, 7-8 and 5-8, connected at the ends. By way of example, the frame 200 is divided into five rectangular compartments I-V which are disposed one above the other, and which are situated between the respective corner points 1-2-3-4-9-10-11-12, 9-10-11-12-13-14-15-16, 13-14-15-16-17-18-19-20, 17-18-19-20-21-22-23-24 and 21-22-23-24-5-6-7-8. The compartments can in turn be subdivided into subcompartments. Each compartment has four side walls (in the case of compartment I these are the walls with corner points 1-2-9-10, 2-3-10-11, 3-4-11-12 and 1-4-9-12), a bottom wall (in the case of compartment I this is the wall with corner points 1-2-3-4), and a top wall (in the case of compartment I this is the wall with corner points (9-10-11-12). The top wall of a compartment is at the same time the bottom wall of the compartment lying above it, insofar as there is one. Each wall of each compartment is fully or partially closed, in such a way that it is impossible for the birds to put any parts of their body through any openings in the wall, and this prevents compartments lying below from being soiled with droppings. During loading of the container 100 with poultry, compartment I is filled first, then compartment II, etc., until the container is full. Fig. 2a schematically shows a side view, and Fig. 2b schematically shows a front view of a preferred embodiment of a container according to the invention in a position in which the bottom compartment is being filled with poultry. In Figs. 2a and 2b halves of the bottom walls 30, 40, 50, 60 of the top four compartments and the respective side walls 31, 41, 51, 61 connected thereto are slid aside. The sliding directions are indicated by a double arrow. Half of the top wall 70 of the top compartment is also slid aside. Figs. 3a to 3f illustrate the filling of the compartments of the container according to Figs 2a and 2b, of which a cross-section perpendicular to the plane of drawing at the line Q-Q is shown. First of all, the bottom compartment is filled by bringing in chickens by means of a conveyor belt 90 at the same level as the side wall, which is illustrated in Fig. 3a. After filling of the bottom compartment, half of the bottom wall 30, together with the side wall 31, is slid to the right and fixed. The compartment lying above it is then filled, which is illustrated in Fig. 3b, following which half of the bottom wall 40, together with the side wall 41, is slid to the right and fixed. The compartment lying above it is then filled, which is illustrated in Fig. 3c, after which half of the bottom wall 50, together with the side wall 51, is slid to the right and fixed. Figs. 3d and 3e illustrate similar action to those mentioned above. After filling of the top compartment, which is illustrated in Fig. 3e, half of the top wall 70 is slid to the right and fixed, which is illustrated in Fig. 3f, following which the container is ready for transportation. Figs. 4a, 4b, and 5 show in side view by way of example different solutions for full or partial removal of the bottom wall together with a side wall of a compartment according to the invention. In the above-mentioned Fig. 5 a filled circle represents a hinge line perpendicular to the plane of drawing at the place which is taken up during filling of a compartment lying below, and an unfilled circle represents the same hinge line in the filled state of the container. This applies mutatis mutandis to the walls of the compartments shown by solid and dashed lines respectively in Figs. 4a, 4b and 5. Fig. 4a, in which 80 represents (a part of) the bottom wall and 81 a side wall of a compartment, again shows the embodiment according to Fig. 2a, and Fig. 4b a variant with a larger number of divisions of the bottom wall. Fig. 5 shows an embodiment in which the bottom wall is sub-divided into strips by means of a large number of hinge lines in such a way that the bottom wall can be moved sideways by means of rolling up. In Figs. 1-3 the container is always shown comprising five compartments, as is customary in the United States of America. Of course, the containers can also comprise a different number of compartments, for example four, as is customary in Europe. The frame 200 of the container can be made of wood or plastic, but it is preferably made of metal, for example of tubular aluminum sections. The bottom wall of each compartment and the side wall thereof at the filling side of the container are made of, for example, a perforated metal or plastic plate. The walls of the container, with the exception of the top wall, the side wall at the filling side and the side wall at the emptying side, are provided with, for example, a fine wire mesh. The container can be filled by hand or by a fully or partially mechanized method, for example using a conveyor belt. The removal or replacement of the bottom and side walls of the compartments can also be manual or motor-driven. The containers are placed, for example, two at a time on a lorry for transportation.
