Abstract

An insert for a container, in particular for a mesh container, comprises a foldable frame with a number of side pieces (2, 3, 4, 5). A pocket (8) or a cover for the protection of the contents of the insert from contamination is fixed to at least one of the side pieces (2).

Description

Container for bulk objects and element of associated insertion.

The present invention relates to a container for objects that can be poured, and especially to an insert that It can be used in combination with such a container.

For storage and transport of objects, such as semi-finished pieces or individual pieces used in industrial manufacturing, calls are often used transport cages These are robust, stackable containers, multiple use, which within a framework of metal profiles they have side walls based on a metallic fabric robust large mesh. The objects that are being transported or Store can be stacked in one of these transport cages, and compact and sufficiently large objects can also be just throw inside.

In order to use a transport cage of this class, also for objects that are smaller than light of wire mesh or parts outstanding that could stand out without mesh protection of the wire cloth, and breaking, it is usual to coat the cage of transport first inside with a waterproof bag, and Throw the objects into the bag. It is true that this way protect objects by preventing them from falling or being damaged or get dirty, in case of long and lasting storage, but without however the bag is annoying when it comes to take out individual objects contained therein, for example to Use them in a manufacturing process. Like the sack, after remove an object, always collapse on itself, the operator always needs both hands to remove the objects, one to keep the bag open and the other to hold the object.

To remedy this problem, at least in a way partial, it is a known fact to stabilize the bag by pieces of cardboard and other flat objects, which are introduced into the inside the bag, between the wall of the bag and the objects there contents, in order to press the wall of the bag against the opposite side walls of the transport cage and keep well open the sack. Now this way of proceeding is only possible if the objects contained in the bag are sufficiently robust to withstand without damage the introduction of the cartons, and as long as there are enough items in the bag to hold down the pieces of cardboard against the side walls of the cage of transport. When the number of objects is no longer sufficient to this pieces of cardboard fold inwards and hinder additionally the removal of objects.

Transport containers are described between others in EP 373506 A1, in U.S. Pat. 5,074,460, in CH 471002 A, in SE 8007334 and in DE 8500532 U1. He transport container described in EP 373506 A1 It comprises a frame with which a bag can be fixed. He transport container described in U.S. Pat. 5,074,460 It comprises a moisture impermeable bag. The container of transport known from SE 8007334 comprises a cage of outer transport covered with cardboard. The cardboard has a waterproof plastic coating. By patent DE 8500532 U1 a folding box that can be folded flat with a bag is known square bottom stuck inside, which in raised position It forms a parallelepipedic packaging.

The objective of the invention is to create a container for objects that can be poured, or create an insert for such a container, which are suitable for housing small objects, protect them effectively against dirt during storage and transport and allow removal of simple way individual objects until full emptying of the container

The objective is solved by employing a insert having the characteristics of claim 1, or a container with an insert of this class according to the claim 15.

The insert comprises a bottom piece that is joined folding with one of the side parts, and that supports by below the objects contained in the insert, eventually surrounded for a sack. To facilitate the removal of the bottom piece at fold it, it has a grip.

An insert of this class comprises conveniently two longitudinal parts and two parts transversal. To be able to remove the insert comfortably from the container after having emptied it completely, the parts transverse sides can preferably be folded in such so that the insert that could be folded completely inside the container For this purpose, the side parts cross sections preferably comprise two equal halves size, folded together.

Due to the bottom piece, the insert can already be enough to prevent small objects from falling out of the transport cage through the gaps of the meshes. In In this case, the bag can be reduced to a simple canvas that covers the objects to protect them against dust.

The side part that is attached to the part of the background is preferably the same to which the cover. When the lining is placed in this way it can remain inside the insert when it is folded, without disturbing Appreciable when folded.

Also the bottom part comprises preferably at least two elements joined together so folding.

The gripping element is then located preferably in the vicinity of the junction between the two elements joined together in a foldable way, or in that of the two elements that are not attached to a side part.

At least one of the side parts is also preferably provided with a cut, which in state Insert folding matches the gripping element. This way is offered the possibility of simultaneously grabbing the grip element of the bottom part and the side part, preventing in this way that when removing the insert out of the container the insert is deployed.

According to a first preferred embodiment, the transverse lateral parts each comprise an element in the form of a band, adjacent to the side part attached to the part of the bottom, and whose width corresponds to twice the thickness of the part From the bottom. This band-shaped element offers the possibility of first lifting the bottom part and folding to then the transverse lateral parts on the part of the bottom, thus forming a compact body that can be removed With ease of container.

According to a second preferred embodiment, the bottom part can be folded around the parts folded sides.

The lining is preferably of a type such that I can close repeatedly. If it is made in the form of a sack, you can especially present a closure tape to return to close it

In this way the effect of protection against dirt even if objects have already been removed container.

To keep the lining permanently open, while parts are being removed, they are also preferably provided means for temporarily fixing the liner to at least one Second lateral part.

Other features of the invention are deduced. of the following description of embodiments with Reference to the figures.

The figures show:

Figure 1 a perspective view of an insert according to the invention, in a full state;

Figure 2 a view of the folding frame of the insert of Figure 1, in an unfolded position;

Figures 3 and 4 views of the frame of Figure 2, in the two phases of folding;

Figure 5 a perspective view of the frame folding according to a second embodiment;

Figures 6 and 7 views of the frame of Figure 2 in two phases of folding; Y

Figure 8 a third embodiment of the frame folding.

Figure 1 shows a perspective view of the insert according to a first embodiment of the invention. The insert It consists of a folding frame 1, for example cardboard corrugated, which has two longitudinal side parts 2, 3 and two transverse lateral parts 4, 5. The lateral parts 2 to 5 they are linked together, in each case, in the corners, so folding. The edge lengths of frame 1 are adapted to the interior dimensions of a transport cage. In particular the height of the side parts has been chosen such that these reach barely below the angular profiles  surrounding the upper edge of the transport cage, and that guarantee the stacking capacity of transport cages.

As represented here, the parties lateral 2, 3, 4 and 5 can all have the same height, and to be united in all their height in the edges taken from each other. But adapting to the typical structure of a transport cage, the edges of the longitudinal side part 3 may be lowered from above to the height of a dashed line 6, and along of line 6 there may be a die cut, so that zone 7 of the longitudinal side part 3 located above the line 6 is can easily fold down, in order to access the insert content even if stacked on top of another cage transport. For this same purpose it can also be omitted alternatively zone 7.

Bag 8 full of the objects that it is about store is subject to the side 2. It can be a permanent fastener, for example of a fastened fastener, but you can also imagine not setting the restraint until you are open bag 8, to extract pieces of it. To keep the open bag, for the extraction of objects, are planned also in the other side parts 3, 4 or 5 means for temporary fixation of the bag. As fasteners of this class double-sided adhesive gaskets are suitable, for example, one face stick to one side and against whose other face it You can squeeze the sack, if necessary, and you are in conditions for releasing the bag without damage when it is going to close again partially emptying

In order to comfortably close the bag again, this one takes in the area of his mouth, which is represented here closed, a traction joint 10.

Figure 2 shows a perspective view of the frame 1 only, without the bag 8. A bottom piece 11 is observed here which serves to support the bag and its contents. It is united in a way foldable to the bottom edge of the longitudinal side part 2. The bottom part 11 comprises two elements 13, 14, joined together folding along a die cut 12, and which are both provided of a cut to grab 15 in the vicinity of the die cut 12.

The width of the bottom part 11 is slightly smaller than that of the longitudinal side part 2, as it can be seen through the narrow gap 16 between the bottom 11 and the transverse lateral part 4. Thus, when the insert is in the position represented in figure 2, it is comfortably possible to hold one of the two cuts to grab 15, lift the bottom part 11 and fold it to it time along the die cut 12. Figure 3 shows frame 1 with the bottom part 11 raised this way.

Once the bottom part 11 has been pressed flat against the longitudinal side part 2, you can begin to fold the transverse lateral parts 4, 5.

The transverse lateral parts 4, 5 are subdivided by means of vertical die cuts 17, 18 in a narrow element 19 in the form of a band and two halves 20, 21 that They are essentially the same size. The width of the element in band shape 19 is represented disproportionately large in the figures, and corresponds approximately to twice the thickness of the bottom part 11, eventually something else, so that the longitudinal side wall 2 and the bottom part 11 is also can comfortably compress the empty bag 8. Figure 4 shows the frame 1 with transverse side parts 4, 5 partially folded When fully folded, the two halves 20 they are directly attached to element 14 of the bottom plate. A clip for grabbing 22 of the longitudinal side part 3 is arranged in such a way that in the folded state of it coincides with the clippings 15 of the bottom part 11. Of this mode can be safely seized by a single manipulation, through the grip cutout 22, the grip cutout 15, and take it out of the transport cage without the risk of produce an unwanted deployment.

In the second embodiment of the frame 1 represented in figure 5, in the unfolded state, the parts transverse sides 4, 5 are subdivided by a single die cut 18 in two identical halves 20, 21; the element is missing in band form 19. Instead, fund part 31 is subdivided by three punched 34, 35 and 36 into two elements in the form of a band 37, 39 and two large surface elements 38, 40. In this case the width of the band-shaped element 37 corresponds approximately to twice the thickness of the parts lateral, and that of element 39, triple this.

When folding this frame they are first cast inward the transverse lateral parts 4, 5 by the die cut 18, as shown in figure 6 and compress against the longitudinal side part 2 and the bag 8 (which not represented) Then you can grab the part of the bottom 31 for its clipping to grip 15, and lift it. The position resulting is represented in figure 7, rotated 180 ° with with respect to the perspective of figures 5 and 6. The width of the large area element 38 corresponds to the height of the lateral parts, so that the die cut 35 becomes the height of the upper edge of the side parts. From the position shown in figure 7 now folds the part of the bottom along the die cuts 35, 36 so that the element in the form of a band 39 rest on the upper edges of the side parts, and the large surface element 40 is attached on the outside to the longitudinal side part 2, as indicates by means of arrow 41. In this position, the cutout for grab 15 of the bottom part matches the clipping to grab 22 of the longitudinal side part 2, so that the user can comfortably grab, through the cuts to grab 15, 22, in the remaining hollow space 42, conditioned by the thickness of the transverse lateral parts between the two longitudinal side parts 2, 3, thus removing the frame comfortably out of the cage for transport.

Clipping to grab 15 can not only be made as a hole but may have a section in C-shape, with a flip tongue that stays inside and that when taking the frame out of the transport cage is pushed into the cutout to grab and the hole 42, keeping thus the frame also in a folded state after leaving it.

The frame can be removed in this way simple without damage outside the transport cage, keeping it taking up little space for a new use.

Figure 8 shows a third version of the Insert, in a perspective view. As in the previous embodiments, insert 1 is foldable, and for this purpose it can have the same arrangement as the one shown in figure 1 or in figure 4. Frame 1 forms down and sideways a sealed envelope that protects objects that They fill it up. For that reason, the sack that in the first two realizations surround objects on all sides, it is reduced by this case to a tarp or flexible sheet 24, which is sized such that you can close the open upper face of the frame one.

This canvas 24 may be fixed at the edges of at least two side parts opposite each other, where at less one of the fixings must be removable and can be close again, for example, using adhesive tape, such As mentioned above or Velcro tape. Figure 8 shows an embodiment where the detachable fastener is formed by a rigid stirrup 25 with hooks 27 that start from the outer the transverse lateral parts 4, 5 and that in state closed fits two notches 26 in the corners of the frame. A semi-open state is represented, where stirrup 25 rest in a central area on the edges of the parts transverse sides 4, 5. In fully open state, the stirrup 25 with canvas 24 can also be folded out of the cage of transport containing insert 1.
