The invention relates to a transport and storage container of plastic according to the preamble of patent claim 1.
Such containers are known as solid boxes or as folding boxes with swingable sidewalls and are oftentimes used for the transport of articles in the household but also in the storage and transport field. As such containers also transport valuable or sensitive items, especially when used commercially, they generally have a lid and can be closed and provided with a safety device, like for example in the form of a seal, to prevent unauthorized opening of the containers. These containers are generally stackable. When using containers of this type as storage containers, stacked containers encounter the problem that a removal of goods from the lower containers of a stack requires a rearranging of containers stored on top in order to be able to remove goods from a subjacent container.
It is therefore the object of the present invention to create a transport and storage container of the mentioned type which enables a removal of goods from stacked containers without the need to rearrange containers stored on top, and which as transport container can essentially not be manipulated, is easy to manufacture and to assemble as well as easy to handle.
This object is attained by a transport and storage container with the features set forth in claim 1.
The transport and storage container of plastic in accordance with the invention includes a bottom part and four sidewalls which are articulated to the container bottom when configured as folding box and preferably swingable open inwardly towards the bottom, with each two confronting first sidewalls being detachably engageable with the two other confronting second sidewalls in the corner regions of the collapsible storage and transport container. For this purpose, the two first sidewalls have in the two upper corner regions latching bars which are respectively engageable at the edges of the two second sidewalls behind respective detent noses for locking the sidewalls, when swung open. The storage and transport container has at least in one sidewall, preferably in the two confronting second sidewalls, a removal opening which can be closed by a lid. This lid can only be opened from the inside of the container. The lid is closed during transport of the container and cannot be opened or manipulated from the outside. For storage, the containers are stacked in such a way that a removal opening of each container is accessible form the front. Prior to stacking the containers, the lids are partially or entirely opened so that the goods contained in the container can be removed from the container.
Further advantages of the invention are set forth in the dependent patent claims and ensue from the following description in which the invention is described in greater detail with reference to an exemplary embodiment shown schematically in the drawings.

The storage and transport container according to the invention is shown in the figures in a collapsible configuration with a removal opening 2 in a sidewall which is swung open. The removal opening 2 may, however, also be arranged in a sidewall of a storage and transport container which sidewall is fixedly connected to the bottom. FIG. 1 shows a perspective illustration of a sidewall 1 of a collapsible container with fully opened removal opening 2, with lid 3 being swung open as viewed from the outside. The lid 3 includes two parts which are connected to one another by hinges and involve an upper lid element 3a and a lower lid element 3b. The upper lid element 3a has been fully folded back to the outside and rests upon the outer side of the lower lid element 3b. Both lid elements 3a, 3b are of different height in this embodiment, with the lower lid element 3b having a height which is approximately twice the height of the upper lid element 3a. The two lid elements 3a, 3b may, however, also have a same height. The sidewall 1 has a frame-like shape with abutment edges 4 formed on the side margins of the removal opening 2 against which abutment edges the closed lid 3 bears. The lower lid element 3b is hinged by hinge elements 14 to the sidewall 1 at the lower side margin 5 of the removal opening 2. At least one horizontal pin 7 is formed on each of the two vertical side margins 8 of the removal opening 2 in the direction removal opening 2. When closing the lid 3, the lower lid element 3b is first folded up and pushed upwards. As soon as the lid element 3b rests against the abutment edges 4 and is then pushed downwards, the pins 7 engage respective recesses 13 at the side margins 9 of the lid element 3b and hold the lid element 3b in the removal opening 2. To fully close the removal opening 2, the upper lid element 3a is folded up and pushed against the abutment edge 4. Arranged in the upper corner regions of the upper lid element 3a are latching bars 10 which can be latched detachably with the sidewall 1 and engage in the sidewall 1 when the upper lid element 3a is pressed against the abutment edges 4.
FIG. 2 shows a sidewall 1 of a collapsible container with a removal opening 2 with partially closed lid, as viewed from the outside. The lower lid element 3b is folded shut and held in the sidewall 1 by the pins 7. The grips of the latching bars 10 can be seen in the corner regions of the outwardly folded upper lid element 3a. These grips can be grabbed only from the inside of the container. The latching bar and its grip are concealed by a cover 12 on the outside of the lid element 3a.
FIG. 3 shows a sidewall 1 of a collapsible container with a removal opening 2 with partially closed lid 3, as viewed from the inside. The lower, closed lid element 3b conceals the outwardly folded upper lid element 3a to the outside. Further shown are the detent noses 11 on the vertical side margins 8 of the removal opening 2 for detachably engaging the latching bars 10, arranged in the upper corner regions of the upper lid element 3a, with the sidewall 1.
FIG. 4 shows a sidewall 1 of a collapsible storage and transport container with a removal opening 2 with closed lid 3, as viewed from the outside. The covers 12 of the grips and the latching bars 10, respectively, can be seen in the upper lid element 3 in the two upper corner regions. These covers resemble the shape of a can. The lower lid element 3b has form elements 12′ which complement the covers 12 and are arranged in such a way that the covers 12 engage these form elements 12′, when the lid element 3a has been folded outwards. The latching bars 10 engage detent noses formed in the form elements and hold the outwardly folded lid element 3a in position. Actuating the latching bars 10 releases the engagement and the upper lid element 3a can be folded up.
FIG. 5 shows the sidewall 1 of the collapsible container with closed lid 3, as viewed from the inside. The grip portions of the latching bars 10 can be seen in the upper lid element 3a in the two upper corner regions. Pulling up the grip portion of the latching bar 10 releases the upper lid element 3a which can be swung to the outside. As the grip portion of the latching bar 10 is accessible only from the inside, the removal opening 2 can thus be opened only from the inside as well.
FIG. 6 shows a perspective illustration of a detail of the lower lid element 3b, as viewed from outside. FIG. 7 shows the respective detail of the sidewall 1 with the removal opening 2 without lid elements 3a, 3b. The hinge elements 14 with attached pins 15 which extend in parallel relation to the bottom edge of the lid element 3b and engage slotted bores 16 in the lower side margin 5 of the sidewall 1 can be seen. As a result, the hinge elements 14 and thus the lower lid element 3b are swingably mounted in the sidewall 1. Vertical webs 18 can be seen in recesses 17 in the lower side margin 5 of the sidewall 1 and engage the recesses 19 of the hinge elements 14, when the lower lid element 3b is inserted and raised, to prevent the possibility of a displacement of the pins 15 to the side. These webs 18 prevent the pins 15 from being pushed or pulled out of the bores 16 as a result of manipulation or improper use of the container, the sidewalls 1, or the lower lid elements 3b. To fold the lower lid element 3b outwards, the lower lid element 3b is raised until the pins 15 of the hinge elements 14 are positioned at the upper edge of the slotted bore 16. In this position, the lower lid element 3b is released in the recesses 13 from the pins 7 on the vertical side margins 9 of the sidewall 1 and can be folded to the outside.
In the exemplary embodiment, the lid 3 is hinged to the lower side margin 5 of the sidewall 1. It is, of course, also conceivable, to connect the lid 3 with the sidewall 1 at the upper or a vertical side margin 8. By covering and closing the removal opening 2 in a sidewall 1 of the transport and storage container, it is possible to remove goods from stacked containers, without the need to rearrange the containers stacked on top. The connection of the lid elements 3a, 3b with one another as well as with the sidewall 1 does not need any additional parts and can be connected only by being plugged together and does not require any further mounting aids. This simple assembly and handling of the lid in the sidewall of the container saves costs during manufacture and simplifies also replacement of defective parts.
