DETAILED DESCRIPTION

(6) In accordance with an advantageous technical aspect, the stop rim portion comprises a projecting fold with an inner rim portion (with the surface normal pointing inwards) against which an outer rim portion (with the surface normal pointing outwards) of the lid part comes to rest in the closed state of the pallet container. The folded configuration ensures secure positioning which prevents the lid part from slipping out of the tensioning element.

(7) Advantageously, the side part, the bottom part, the top part and the lid part each comprise an outer cardboard layer and an inner cardboard layer, whereby the at least one vacuum insulation panel is disposed between the cardboard layers. The two cardboard layers advantageously are designed in such a way that the vacuum insulation panels are fully enclosed on the sides thereof.

(8) According to a further technical aspect, the edge protection element comes to rest loosely against the outer cardboard layer or is firmly connected to the outer cardboard layer. The firmly embodied arrangement provides the advantage that the lid part can be handled jointly with the edge protection element, while the loose arrangement provides advantages during transport.

(9) Another preferred aspect is that the inner cardboard layer of the lid part comprises the outer rim portion. This aspect ensures that the inner cardboard layer rests against the inner rim portion and is tensioned against the inner rim portion by a force applied by the tensioning element to the outer cardboard layer.

(10) The outer rim portion on the lid part is preferably formed by an edge running continuously over three sides with an inwardly offset partial portion. The fourth side, without an inwardly offset partial portion, is preferably placed on the bottom part, since the entire weight rests on this wide edge when the lid is placed on it.

(11) Another advantageous aspect is that the inner cardboard layer includes receiving elements for refrigeration elements. For example, the receiving elements can be formed by U-shaped rails which are disposed relative to each other in such a way that the refrigeration elements can be inserted between them.

(12) Advantageously, the edge protection element is made of cardboard or plastic. Both materials make it possible to realize a rigid configuration of the edge protection element and are comparatively inexpensive to manufacture.

(13) Particularly preferably, the tensioning element is configured as a length-adjustable tensioning belt or an elastic strap. The elastic strap, for example, can be made of a rubber material.

(14) In accordance with an advantageous aspect, the pallet container comprises three (separate) adjacently disposed side parts. The separate side parts can be transported compactly stacked for transport and, thanks to the combination of edge protection element and tensioning element, are provided with a good connection for use during transport.

(15) In the following, the invention will be explained in more detail using the examples shown in the attached figures.

(16) FIG. 1 shows a pallet container 1 for the transport of temperature-sensitive products in a perspective view.

(17) In the example shown, the pallet container 1 has three side parts 21 (respectively two side parts on the right/left and one rear part), a bottom part 22 and a top part 23. The pallet container 1 is shown open, i.e. without the lid part.

(18) On the opened side, two opposite side parts 21, the bottom part 22 and the top part 23 have a common fully circumferential stop rim portion 4. When the pallet container 1 is closed, the lid part comes to rest firmly against the stop rim portion 4. The stop rim portion 4 has a projecting fold 41 projecting from the outer side with an inner rim portion 42.

(19) When the pallet container 1 is in the closed state, a complementarily embodied outer rim portion (see FIG. 2) of the lid part rests against the inner rim portion 42. Due to the configuration with a stop rim portion 4 in combination with an edge protection element 7 and a tensioning element 6 (see FIG. 4), both a stable pallet container 1 is provided and an air-permeable closure is created, for which reason the disadvantages of prior art with regard to the air-tight closure, in particular with regard to the use of dry ice, do not occur.

(20) The pallet container 1 at each edge thereof has an edge protection element 7 made of cardboard (in the example shown) extending over the entire edge. The edge protecting elements 7 may be mitered at the end portion. In the example shown, the edge protection element 7 is glued on respectively one side to the respective outer side (outer cardboard layer 52; FIG. 3).

(21) The pallet container 1 is designed as a pallet on the underside thereof in such a way that fork tools of a forklift truck can be inserted.

(22) FIG. 2 shows a lid part 24 as it can be placed on the opening of the pallet container according to FIG. 1. When the pallet container is in the closed state, the outer rim portion 43 of the lid part 24 comes to rest against the inner rim portion of the side part and the top part. For this purpose, an edge running continuously over three sides is formed on the outer rim portion 43 of the lid part 24 with an inwardly offset partial portion 431.

(23) FIG. 3 shows an exploded view of the basic structure of a side part, bottom part, top part or lid part using the example of a side part for the pallet container according to FIG. 1.

(24) As seen from the left to the right, the structure comprises refrigeration elements 8 with fastening profiles 81, an inner cardboard layer 51, four vacuum insulation panels 3, an outer cardboard layer 52 and edge protection elements 7.

(25) Between the outer cardboard layer 52 and the inner cardboard layer 51 the vacuum insulation panels 3 are arranged in such a way that they are laterally enclosed by the inner cardboard layer 51. The inner cardboard layer 51 comprises the outer rim portion 43 at the lid part. The receiving elements 81 for refrigeration elements 8 are attached to the inner cardboard layer 51.

(26) The closed pallet container is shown in FIG. 4. Thereby, the lid part according to FIG. 1 is placed on the opening of the pallet container according to FIG. 1. In the example shown, two tensioning elements 6 are arranged one above the other in the form of a tensioning belt.

(27) The respective parts of the pallet container described above without lid part can be seen again in detail in FIG. 5 to FIG. 8, so that the construction of the pallet container becomes clear. The top part 23 has a circumferential rim 231, the width of which corresponds to the thickness of the side parts 21 (respectively two side parts in FIG. 6 and one rear part in FIG. 7). The bottom part 22 (FIG. 8) has an identical rim 221. The side parts 21 in FIGS. 6 and 7 have a stop rim portion 4 against which the lid part (further side part) comes to rest firmly. The stop rim portion 4 has a projecting fold 41 projecting from the outer side with an inner rim portion 42.
