Abstract

A box for receiving bulk loose goods, in particular fruit, vegetables or the like, has a bottom (1), end and sidewalls (3, 4), and at least one handle (5, 6; 27, 28) hingedly linked to two opposite walls (3, 4 or 5, 6). The handle can be brought from a position in which the reception opening is clear into a position in which the reception opening is partially covered. The box, the hinge (16, 30) and the handle (7, 8; 27, 28) are made of the same material.

Description

Bowl with bracket

The present invention relates to a bowl for holding lumpy goods, in particular fruit, vegetables or the like, with a bottom, end and side walls and a blank.

Such shells are known and used in a variety of forms and designs. So that the contents of such trays do not accidentally fall out, the filled trays are generally closed by means of a transparent stretch or shrink film. As a result, the content is reliably held in the tray and can also be visually inspected from the outside, but the disposal of such packaging from a mixed material will pose considerable problems. According to future regulations, for example, only substances made of the same material may be in a garbage container. In this case, plastic film should never be mixed with a cardboard tray.

SHEET From CH-PS 669 937, for example, a carrier is known in which the carrier itself and the carrier tape is produced from a blank. A reinforcement tape can also be glued to this carrier tape.

In an unfilled position, this carrier tape is still connected to an upper edge of an end wall section, which makes it easier to fill in the carrier container and also to stack it, in particular in the unfilled state. After filling, a pivoting movement of the carrier tape takes place in such a way that the side of the carrier tape lying outside in relation to the carrier container points in the swung-open state towards the interior of the container.

A disadvantage of such a container is, on the one hand, that the carrier tape itself is not very stable and is therefore usually still covered with a plastic strip. However, this carrying container again has two different materials, the disposal of which is difficult today. Furthermore, it is also more difficult to erect the strap because it has to be rotated. As a result of this arrangement, the crease line between the link linkage and the carrying container is also heavily stressed, so that tearing occurs here.

The present invention has for its object to provide a Schllae of the above type, in which the content is retained in the shell without using different material and still an optical inspection of the goods is guaranteed, in particular the stability of the entire shell and its handling is significantly improved. To achieve this object, at least one bracket is articulated to two opposing walls, which bracket can be brought from a position leaving a receiving opening to a position partially covering the receiving opening, the shell, joint and strip or bracket being made of the same material are.

This takes account of both requirements. Shell, joint and strip are made of a uniform material so that they can also be disposed of together in a garbage can. The bracket only partially covers the receiving opening of the bowl, so that the contained product can be inspected. For example, apples in this bowl can also be turned over to find out whether the apples already have brown spots. This makes this bowl very customer-friendly.

In one embodiment of the invention, the shell is preferably to be made from a blank, on the other hand the bracket or brackets are also made of the same material, but are fixed separately to the shell previously produced. Above all, the joint connection used later in a preferred exemplary embodiment of the invention is to be used here. This articulated connection consists of a simple rondelle, which in the position of use sits in one eye of a tab, the tab being bent off the bracket. The rondelle is connected to a wall of the shell, for example by gluing. At the opposite end of the bracket there is also a tab with one eye, which also rotates around a rondelle fixed to the opposite wall. Since the rondelle itself is preferably punched out of the bracket, an articulated connection of the same material is created here as is also used for the shell or for the bracket. So that the rondelle in the eye

REPLACEMENT LEAF the tab is held, it is preferably clamped between the wall of the shell and a corresponding tab, although the tab itself does not have a clamping effect on the tab itself. This prevents the tab from slipping off the rondelle.

It must also be clearly stated that a material that is very environmentally friendly is particularly preferred. This includes in particular recyclable cardboard. For this reason, cardboard materials are very preferably used in the present invention both for the shell, bracket and for the articulated connection.

In a preferred embodiment of the invention, in which, above all, the entire manufacture of the shell is made considerably easier and cheaper, all parts of the shell, the joint and the stirrups are to be produced from a single blank. In the present case, the invention has come up with several special variants for this cutting. This applies above all to the articulated connections, with only two articulated connections having the configuration described above with the rondelle sitting in the eye. In another articulated connection, the bracket is coupled to the blank via a corresponding gusset and remains firmly connected to the blank even after the bracket has been folded up.

All embodiments have in common that the bottom is connected to the brackets by means of folding lines with end and side walls and the side walls are in turn connected by punching lines. In this case, flaps are also provided on the side of the side walls, which in use position at least partially rest against the end walls from the outside and are connected to them, for example, by adhesive bonding. When speaking of punch lines or punching in the present invention, this includes any other

REPLACEMENT LEAF Cut into the blank. Furthermore, the punching lines are generally not continuous, but are interrupted by appropriate breakpoints. These breakpoints are broken later so that the bracket can then be removed from the side walls. The same applies to the rondelle in the eye.

The flap just mentioned is used for the above-described fixing of the rondelle between itself and the end wall of the shell, provided that a swivel joint with a rondelle rotating in one eye is used. In the other case, the rag is used to fix the side wall to the end walls.

Doubling strips are preferably provided for side walls and brackets, these doubling strips being connected to the brackets in each case via a folding line.

They in turn have a connection to one another via a corresponding punching line. When the shell is being produced, these additional strips are bent around the above-mentioned crease line, so that they rest against the side wall and the bracket from above or below and can be fixed thereon by gluing. The two punch lines are also one above the other so that they can be broken open. Additional side tabs can also be formed on the outermost strips.

A simple form of the invention uses a joint which is formed over a gusset already mentioned above. This gusset is located between two lines arranged at an angle to one another, which start from the end of the punched line between the side wall and the bracket. It is thus framed by the above-mentioned tab on the side wall and an additional section on the bracket. When the stirrup is erected, the two lines just mentioned are folded in opposite directions, so that the stirrup quasi through the end of the punching line

REPLACEMENT LEAF defined pivot point rotates. Finally, the gusset lies against the rag from the outside.

However, preferred embodiment with a rondelle, which is in the above. Eye sits. In this case, the embodiment is preferred in which the tab bracket is molded on itself, this tab being able to be at least partially stamped out of the tab, for example. When reassembling, the reinforcement strips are applied to the bracket and the side wall from below, so that the tabs and rondelle as well as the tab of the side tab already mentioned are deposited on the outermost strip. The main advantage of this arrangement is that only one adhesive application for all parts to be connected has to be done from one side.

In the second embodiment, on the other hand, the tab is formed laterally on the strip connected to the bracket or punched out of the side tab. In this case, the reinforcement strips are then placed on the side wall and bracket, although, for example, the rondelle must be provided with an adhesive layer from both sides. This is an additional step. The punching lines mentioned above should also be curved. It has been shown that these curved punch lines hold together much better despite fewer breakpoints. On the other hand, it is easier to break up later than with a straight one due to the smaller number of stops.

Overall, a shell is created which can be produced inexpensively from a blank in one work step and which in particular consists of the same material throughout, so that disposal does not pose any difficulties.

The cardboard tray shown in Figures 1 and 2 has a bottom 1, two end walls 3, 4 and two side walls 5, 6. The cardboard tray is formed from a one-piece blank and the walls 3-6 are glued to one another at suitable points in a manner known per se.

The special feature of this tray intended for packing fruit, fruits and the like is the bow-like cardboard strips 7 and 8, which run as parts of the tabs 9, 10 glued to the end walls 3, 4 from the respective end wall plane above the side walls to the other Extend end wall. This in the so-called open position of the shell, i.e. with the shell opening freely. In this position (Figure 1), the contents (e.g. fruit) can be filled into the bowl.

The cardboard brackets 7, 8 can be folded upwards by applying an external force (closed position, see FIG. 2), in order to prevent the contents from falling out unintentionally, but at the same time to ensure a good view of the contents.

The sections 7 ′, 7 ″ and 8 ′, 8 ″ of the stirrups 7 and 8 lying in the end wall planes are folded along the lines 11, 12 when they are opened, which form a gusset 16 between them. The fold lines 11, 12 are like this

REPLACEMENT LEAF trained to hold the stirrups in the open or closed position using the cardboard elasticity.

Both the brackets 7, 8 and the side walls 5, 6 have at least one recess 13, 14 into which mechanical or, if necessary, a finger can be used to grip the

Fold up the bracket.

As mentioned at the beginning, with this construction of the bowl, using only one raw material (cardboard), packaging can be created which is suitable for packaging fruit, fruits and the like.

The flat cardboard blank from which the shell is formed enables various parts of the shell to be reinforced by flanging.

Fig. 3 shows a flat cardboard blank, which is used to form the trays of FIGS. 1 and 2. The different parts of the blank are marked accordingly.

During or after production of the blank for the shell according to the invention, further punching lines have to be drawn. This includes the punching line 17 and 18 for releasing the end walls 3 and 4 so that they can be set up around the folding lines 19.

Furthermore, the brackets 7 and 8 must be detachable from the respective side walls 5 and 6. For this purpose there are punching lines 20 between the side walls 5 and 6 and additional strips T, 6 ^" and 7, ^" δ ^" . The strips T and ^~ 8 ^* are each connected to the bracket 7 and 8 via folding lines 15, whereby via these folding lines 15 the additional brackets 5, 6 and T, -T placed on the side walls 5 and 6 and the strips 7 and 8 and glued there for reinforcement

REPLACEMENT LEAF can. Accordingly, a further punching line 23 must also be present between the strips 5 ^* and T and ^~ 8 ^~ and 6 ^" , which after folding by the folding line 15 lies above the punching line 20. Both punching lines 20 and 23 are not continuous, but rather the respectively adjacent ones Strips are still connected to each other by holding points 24, which are only broken when the brackets 7 and 8 are raised.

Thus the strips 5 ^~ , T and ~ and ^" B ^~ are first folded around the fold line 15 and glued to the side walls or brackets 6, 8 and 5, 7. Now the end walls 3 and 4 are set up around the fold lines 19 and an erection of the reinforced side walls 5 and 6 together with the brackets 7 and 8 around the fold lines 19. Then the tabs 9 and 10 are bent together with the gussets 16 around oblique lines 25 so that they strike the end walls 3 and 4 from the outside and be stuck there.

After the tray has been filled with the corresponding product, the brackets 7 and 8 are erected, the punching lines 20 and 23 and the breakpoints 24 breaking. Simultaneously with the erection of the brackets 7 and 8, the gussets 16 are rolled over the respective line 11, the line 12 also buckling. After the brackets 7 and 8 have been erected, the gussets 16 each lie between the tabs 9 and 10 and the brackets 7 and 8, respectively.

According to FIG. 4, a further shell according to the invention has a base 1, two end walls 3 and 4 and two side walls 5 and 6. The cardboard tray is formed from a one-piece blank and the walls 3 to 6 are glued to one another at a suitable point in a manner known per se.

REPLACEMENT LEAF The special feature of this bowl intended for packing fruit, fruits and the like lies in a bow-like cardboard strip 27 which forms a regular swivel joint with the remaining part of the bowl. For this purpose, a tab 31a is connected to both ends of the strip 27, separated by an oblique line 25a, a tab 32 being located in the tab 31a, which is punched out of the tab 31a in such a way that it is held in the tab only slightly via breakpoints 31a remains. Furthermore, the tab 31a is separated by a continuous punching line 33 from a tab 9, which is connected to the side wall 5 via a folding line 25.

In the present exemplary embodiment, corner strips 38 and 39 are additionally provided between the side wall 5 and the tab 9 or the bracket 27 and the tab 31a for the design of bevelled corners of the cardboard tray. These can, but do not have to be arranged.

A stop edge 22 is also formed on the tab 9, which limits a rotary movement of the bracket 27, as described later.

The bracket 27 is connected to the side wall 5 on the one hand via a punching line 20, on the other hand a reinforcing strip 27 is assigned to it via a folding line 15.

A reinforcement strip _T also adjoins the opposite side wall 6 via a fold line 15, which reinforces in particular the upper edge of this side wall 6.

The folding of this exemplary embodiment of a blank according to the invention into a shell takes place as follows: First, the strip 6 is placed on the side wall 6 and the strip 21 on the bracket 27 and glued. Then the two end walls 3 and 4 are erected and the side wall 5 is set up, the tabs 9 striking the end walls 3 and 4 from the outside. These tabs 9 and the rondelles 32 are glued to the end walls 3 and 4 from the outside.

Now there is an erection of the side wall 6, two flaps 10 formed onto this side wall 6 now lying on the flaps 9 and also covering the rondelles 32. The rondelles 32 can, if desired, be additionally glued to the tab 10. This arrangement, however, forms a rotary shaft between tabs 9 and 10, in which tabs 31a of bracket 27 can move, as shown in FIGS. 5 and 6. For filling, for example, the bracket 27 still remains in the position shown in FIG. 5 and adheres to the side wall 5 via the punching line 20. After the filling or for carrying the shell, the punching line 20 and also the punching line 33 are broken, so that then the bracket 27 can freely rotate around the rondelles 32, these rondelles 32 then being located in an eye 35.

In a further preferred exemplary embodiment of the invention according to FIGS. 7 to 9, above all the movement of the cardboard strips, which are now designed as separate brackets 27 and 28, is significantly improved compared to the other parts of the shell. A regular swivel joint 30 is formed here, as will be described below.

An essential difference is the design of the stripes _ and ^" 28 ^" . To each of these, tabs 31 are connected, separated by an inclined line 25a, a tab 32 being located in the tab 31, which is punched out of the tab 31 so that it is only

REPLACEMENT LEAF held slightly above breakpoints still remains in the tab 31. Furthermore, the tab 31 is separated from the strip IT or _T by a continuous punching line 33. In this case, a stop edge 22 described above also forms on the strip 5 ^~ or ^" _T, which limits a rotary movement of the bracket 27 or 28.

The folding of this exemplary embodiment of a blank according to the invention takes place as follows:

First the strips ^~ 5, 21 and T, ^" 2_T. Are folded inwards around the fold lines 15 so that they come to rest on the side walls 5 and 6 and brackets 27 and 28. This strengthens the side walls and brackets Gluing takes place between the strips 5 ', 6' and the side walls 5 and 6 and between the strips 27, 28 and the brackets 27 and 28, it being evident that the tabs 31 are not fixed by adhesive bonding provided with an adhesive layer so that it adheres to the respective tabs 9 and 10. The end walls 3 and 4 are now erected and the side walls 5 and 6 are erected, the tabs 9 and 10 being attached to the end walls 3 and 4. This takes place with the interposition of the tabs 31 and side tabs 34, which each protrude laterally from the strips 5 and _T and from which the tab 31 is also punched out. These side tabs 34 must be covered with an adhesive tape not be provided so that they stick to the outside of the end walls 3 or 4.

When the brackets 27 and 28 are erected, the holding points 24 break and each bracket 27 and 28 can rotate freely, an eye 35, which is formed by punching out the rondelle 32, rotating about this rondelle 32. A movement of the bracket 27 or 28 is limited by the stop edge 22.

REPLACEMENT LEAF The only disadvantage with this cut is that for the connection of the strips 5, 6 or 27, 28 and the rondelle 32 adhesive has to be applied to the cut from above, in which case the side tabs 34 on the end walls 3 or 4 adhesive has to be applied again to these side tabs 34 from the other side. Here, the cut according to FIG. 10 offers a further improvement, in which case the corresponding shells according to FIGS. 11 and 12 can be formed from this cut. The change relates primarily to the tabs 31a, which are provided on the bracket 27 and 28 in this embodiment. In continuation of the punching line 20, they are shaped out of the tabs 9 and 10 by means of a continuous punching line 33a. Your kink line with the bracket 27 or 28 is part of the inclined line 25 defined above.

In this embodiment, the strips 5, 27 and 6, 2 ^" 8 are folded outwards around the fold lines 15 and thus engage under the side walls 5, 6 or brackets 27, 28. This makes it possible to apply the adhesive from one side only The rear sides of the end walls 3 and 4 are coated in the area of the contact surface of the tabs 9, 10 and the circular plate 32, the back of the tabs 9 and 10 and the strips 5, 6 ^" , ^" 27 ^" and 28 and the side tabs 34a in the area of the rondelle 32.

Furthermore, it can be seen in this exemplary embodiment that the punched lines 20a and 23a are curved. This makes it possible to provide significantly fewer breakpoints 24 per punch line 20a or 23a, so that breaking off the brackets 27 and 28 from the side walls 5 and 6 is also facilitated. In contrast to the straight punching lines according to the first two exemplary embodiments, the blank does not break so easily in the production machine here, so that a

REPLACEMENT LEAF Filling and later erection of the bracket 27 and 28 is much easier.

Also to be mentioned in this exemplary embodiment are holes 36 in the corner regions of the base 1, which on the one hand improves a microclimate in the shell and on the other hand makes stacking of the shells easier. In contrast to straight corners, the trays do not get stuck when stacking.

In Figure 12 is also indicated that the _. a price label or another security strip 37 can be placed on both brackets 27 and 28, indicating that such a shell is unaffected.

It can also be seen from FIGS. 11 and 12 that the side tabs 34a protrude somewhat beyond the end walls 3 and 4, respectively. This has the effect that when the brackets 27 and 28 are opened, the corner regions of these brackets 27 and 28 or parts of the tab 31 are covered by the protruding parts of the side tabs 34a and are thus also protected against mechanical attack from the outside. This is another significant advantage of the present invention.
