Abstract

Transport container (10) with a base and four side walls (11, 12) arranged thereon, characterized in that at least two opposite side walls (11, 12) have a horizontally extending curvature towards the outside and are straight in the vertical direction.

Description

The invention relates to a transport system which comprises a transport container having a base surface and having four side walls arranged thereon and a lid for this purpose having a cover surface, at the outer peripheral edges of which angled side surfaces are arranged.

Such transport containers are well known and find particular their use in the private and domestic field in many ways. The side surfaces on the lid prevent the same from slipping and thus ensure reliable closure of the transport container with the lid.

The present invention has for its object to provide a transport system of a transport container and a corresponding lid, which causes a viewer a relatively edged appearance.

This object is achieved with a transport container having the features of claim 1, a lid with the features of claim 9 and a transport system with the features of claim 14. The further embodiment of the invention is shown in the respective dependent claims.

The transport container described above is inventively further developed in that at least two opposing side walls have a horizontally extending curvature to the outside and are formed in a straight line in the vertical direction. The curvature is not very pronounced, so that the transport container acts on a viewer due to an optical illusion larger and very straight. Due to the bulge in one direction only, a coating of the side wall is possible, for example, with an IML film. If arched in two directions, the film would shrivel.

For a reliable covering with a lid, a substantially horizontally formed, circumferential bearing surface is provided at the upper end of the side walls.

In an advantageous manner, a substantially vertical flanging surface is provided on the outer edge of the support surface. As a result, the upper edge is stabilized with the support surface and flaring surface against deformation in a lateral load.

For a relatively comfortable fit each handle is arranged on two opposite sides of the transport container on the support surface and / or flaring.

So that when using the transport container with a suitable lid, the surface of the handles form a level closure with the lid, the handles of the support surface and / or flanged face are available. Alternatively, the handles protrude beyond the surface of an overlying lid to facilitate centering of the lid.

The handles preferably have laterally at least one recess in which corresponding projections can engage on a lid in order to produce a latching connection.

For ease of manufacture with a stable assembly according to the invention is preferably provided that the handles are composed of a lower part and an upper part and are connected by means of a latching connection with the support surface.

For a simplified movement of the transport container without necessarily lifting it up, in one embodiment receiving means for one wheel are arranged in at least two adjacent corners of the base. Thus, only the side of the transport container without wheels must be slightly raised to move the transport container over a floor surface. When arranged in all four corners wheels can be dispensed with lifting entirely.

The lid described above is inventively further developed in that spaced from the peripheral edges of a circumferential groove is provided which divides the lid surface in a located within the groove part surface and in an outboard groove located edge surface. This supports the angular appearance and strengthens the stability of the lid.

In order to reinforce the angular appearance by means of an optical illusion, the edge surface is preferably substantially planar and the inner surface has an upward pointing curvature in one direction.

Advantageously, recesses in the side surfaces and the edge surface are provided in the lid according to the invention on two opposite sides into which the respective handles of a transport container according to the invention can protrude.

For improved stability, recesses in the edge surface are alternatively provided on two opposite sides.

In order to secure the lid on the transport container, in each case at least one projection is provided in the region of the recess. This Projection serves to protrude when resting the lid on a transport container under the handle or in a trough in the handle, so as to enable a latching connection.

In the transport system according to the invention, the transport container and / or the lid may be made of metal, wood or plastic. A particularly inexpensive production is possible by means of known injection molding of plastic.

An embodiment of the transport system according to the invention, comprising a transport container and a lid, will now be described in more detail by way of example with reference to the accompanying drawings, in which:

1a shows a perspective view of a transport container according to the invention without a lid;

1b a detailed view 1a shows;

2 shows a perspective view of a transport container according to the invention with a lid thereon;

3 shows a detailed view of a transport container according to the invention with an alternative handle;

4 the detail view 3 with an overlaid lid; and

5 a sectional view through the handle of 3 shows.

Based on 1a . 1b and 2 becomes the transport system according to the invention 1 represented, which is a transport container 10 and a matching lid 20 includes. Here is in the 1a and 1b the transport system 1 opened, ie the lid 20 is not on the transport container 10 , On the other hand, in the presentation of the 2 the transport system 1 closed, ie the lid 20 is on the transport container 10 ,

The transport container 10 has a base, which is not visible due to the perspective view and the bottom of the transport container 10 forms. There are four side walls at this base 11 and 12 arranged upright. Here are the side walls 11 a bit shorter than the side walls 12 , The walls may be formed at a slight angle from the vertical outward to facilitate manufacture by an injection molding process. Furthermore, by a slightly conical course of the circumference several transport containers 10 space-saving stacked into each other.

The side walls 11 . 12 have from bottom to top, so in the vertical direction, a straight-line course. On the other hand, in the horizontal direction are the side walls 11 . 12 provided with a slight curvature to the outside. The material or wall thickness, however, remains substantially the same despite the curvature. In a (not shown) viewing the transport container 10 exactly from above, the base is not exactly rectangular, but has at the edge of a curved side wall instead of a straight edge line on a slightly curved edge course.

The vaulting in one direction, besides the effect on the viewer, also has the advantage that the side wall 12 For example, can be coated or printed with an IML film. IML stands for in-mold labeling and is a labeling process applicable to injection molded parts. In this case, the IML foils are inserted into the injection mold and, during actual casting, the foil is joined with the molten plastic of the melt. The film is thereby inseparably connected to the injection molded part.

At the upper end of the side walls 11 . 12 is a substantially horizontally formed, circumferential bearing surface 13 formed at the outer edge of a substantially vertical flanging surface 14 followed. For manufacturability by injection molding, in this case an angle between the side walls 11 . 12 and the bearing surface 13 as well as between the bearing surface 13 and the flanging surface 14 each a few degrees more than a right angle with 90 °.

In the areas of shorter side walls 11 is at the contact surface 13 and the flanging surface 14 on both sides of the transport container 10 each about a handle in the middle 15 provided, which protrudes in each case to the two surfaces in the direction of the surface normal. The handles 15 are thus something of the bearing surface 13 and the flanging surface 14 from. The measure of this projecting distance of the surface of the handles 15 preferably corresponds to the material thickness of the lid 20 ,

The lid 20 has a lid surface 21 on, at the edges of which angled side surfaces 22 are arranged. In the closed state of the transport system 1 is the lid 20 on the support surface 13 of the transport container 10 on and the side surfaces 22 of the lid 20 enclose the crimping surfaces 14 of the transport container 10 , Here is between the bottom of the lid 20 and the side surfaces 22 again provided a slightly larger angle than a right angle. To the one, so the side surfaces 22 on the flaring surface 14 on the other hand, to make a cover 20 to enable injection molding.

In the field of handles 15 is in the lid 2Q one recess each 23 provided in which the respective handles 15 protrude. Because the handles 15 from the support surface 13 in the order of magnitude of the material thickness of the lid 20 Protruding form the surfaces of the handles 15 with the lid surface 21 and the side surfaces 22 of the lid 20 in the closed state of the transport system 1 one level each.

The lid 20 has spaced from the marginal edges a circumferential groove 24 on top of the lid area 21 in one within the groove 24 partial area 25 and one outside the groove 24 located edge surface 26 divided. The inner part surface 25 of the lid 2Q has in one direction, preferably in the direction of the shorter side on an upward-facing curvature. Here is the outer edge surface 26 still trained flat and without curvature.

The distance of the groove 24 from the marginal edges of the lid 20 is dimensioned such that the outer edge surface 26 essentially the bearing surface 13 of the transport container 10 equivalent. The groove bottom of the groove 24 is formed substantially perpendicular to the groove walls, so as the optical illusion of the angular and straight action of the transport system 1 to support a viewer.

In the area of recesses 23 projections or lugs are provided, which when closing the transport container 10 with the lid 20 with the handles 15 form a latching connection or an elastomeric snap closure. It is essential that the handles 15 not on the lid 20 are arranged and the edge of the container 10 handle, as is common in other container-lid systems. The transitions between the recesses 23 of the lid 20 and the handles 15 and the bearing surface 13 of the transport container 10 are designed with small slots to make an airtight closure of the closed transport system 1 to prevent. The louvers and the latching, which can also be opened by light pressure from the inside, thus comply with legal requirements for child protection, so that in the transport system 1 Child on the one hand not stifled and on the other hand himself from the closed transport system 1 can liberate.

Finally, the illustrated transport container 10 in the lower four corners recording devices 16 for wheels 17 on which the transport container 10 can be moved over a bottom surface in a simple manner. The wheels 17 only protrude slightly downwards out of the base. On the side walls 11 . 12 the wheels remain 17 within the spanned, respective areas, in order to continue the possibility of nesting of several transport containers 10 to enable.

Based on 3 to 5 an alternative handle design is shown and explained. The handle 30 again stands from the support surface 13 and the flanging surface 14 However, in this alternative design, more than the material thickness of the corresponding lid (in 3 not shown). On the side surfaces of the handle 30 leading to the bearing surface 13 show are each a trough or depression 31 intended.

In 4 is the detail view of the handle 30 with a lid on top 32 shown. Because the handle 30 even with the overlying lid 32 protruding over this is the lid 32 in the process of hanging up by the handle 30 centered. Clearly visible is the alternative embodiment of the recess 33 in the lid 32 through which the handle 30 protrudes. The recess 33 is on all sides of the edge surface 34 of the lid 32 enclosed. That gives the lid 32 greater stability. On the inside of the recess 33 are latching projections 35 provided with the overlying lid 32 into the wells 31 in the grip 30 intervene and thus the lid 32 on the transport container (not in 4 shown).

According to the sectional view of 5 is the handle 30 from a lower part 36 and a top 37 that are set on top of each other. Here, the handle points 30 at the bearing surface 13 of the transport container 10 facing sides each have a locking connection 38 on that under one edge of the bearing surface 13 clicks and the handle 30 with the transport container 10 clamped connects.
