Abstract

The converted material container (1) consists of a flat plate with slot and appropriately dimensioned sectors give a container of surfaces (10) and surface extensions (11) to form bottom and side and rear surfaces and also complete a receiver profile (3) inside the container projecting in front or back into the closable opening (2). In a variant, using two container parts of identical size made up from plates again by conversion. The three casing surfaces per container are joined at acute, obtuse or right angles to give the extension surface acting as base or rear wall and in this case both container parts are joined to give openings so the extensions close off the openings by flap or cover.

Description

The invention relates to containers according to the preamble of claim 1 or 2 from deformable Material in the form of at least one in itself Circuit board.

So far, by means of relatively complex technical Processes such as deep drawing, containers are produced or become container parts and / or pre-bent container segments using one of the conventional joining methods Containers assembled. With conventional deep-drawing techniques it is not possible already in the source material Breakthroughs, passages, beads, etc. to provide what a Inexpensive manufacture of containers is a great advantage would. A fixed connection of several elements with the help one of the conventional joining techniques to a container the use of expensive special tools or flashbulbs. In addition, are often also appropriate complex and therefore expensive systems for implementation of the various conventional joining techniques.

In Handbook of Fastening and Joining of Metal Parts, Mc Graw-Hillbook Comp. Inc. New York-Toronto-London, 1956 first edition, Page 494 (top right) is the manufacture of a container described, in which a centrally arranged, flat flat, rectangular floor area, on its four sides there are flat extensions. These extensions must each be bent by 90 ° can be connected to one another, for example, by welding. This known container thus has between the bottom surface and rectangular sharp corner areas on the side walls in which dirt inevitably collects or accumulates can. Furthermore, there is no one in this container Well-shaped, fully or partially circumferential profile, for example to accommodate seals. In US 1,582,541 A (corresponds to the preamble of claim 1 or 2) is a container made of deformable material described in the form of a flat board in itself, which a with a number of cuts provided processing of the Containers. This container consists of a number formed from a rectangular unit area Lateral surfaces, from a closed bottom surface, the essentially from partially overlapping lateral surface processes is formed, as well as from one inside the container projecting and provided for reinforcement, bead-shaped Circumferential profile.

This bead-shaped circulation profile is in the known container obtained by punching or cutting the execution by means of appropriate folding devices first the bead-shaped profile is formed. Subsequently are in the extension of the intended bending edges between Mitres corresponding to the individual lateral surfaces in the profile introduced that are dimensioned so that after performing the cutting edges of the miters apply and be joined together by joining can. In this way, a protruding into the interior of the container receive a reinforcing circumferential profile.

In GB 1 103 316 A there is also a container made of deformable Material described in the form of a flat board in itself. In the longitudinal edges of the development of the container to be manufactured are in the extension of the later bending edges between the V-shaped incisions provided lateral surfaces, which so are designed to be in the corner areas of the container forming a flange projecting into the container Edges of the V-shaped incisions abut each other and can be connected by joining.

To meet the high demands in terms of hygiene during use of containers in the hotel and catering trade, in clinics, in food processing companies are sufficient containers that are used there, etc. comfortable and be cleanable reliably, i.e. they are not allowed have difficult to access areas and sections of any kind.

The object of the invention is therefore one in shape and size variably executable container with inside produce the above admission / connection profile, the also in areas with high demands regarding Hygiene can be used and used without having to its manufacture expensive special tools or devices as well as complex systems for carrying out the usual Joining techniques must be used.

According to the invention, this object is achieved by a container and container parts made of deformable material in the form of a in itself flat board according to the preamble of claim 1 or 2 by the features in the characterizing part of each Claim solved. Advantageous further developments are the subject that of claim 1 or 2 directly or indirectly related claims.

Such a container or container part has a preferred Embodiment of the invention as a circumferential profile a u-shaped or v-shaped or trough-shaped in cross-section Recording / connection profile. Furthermore, the cutouts are like this dimensioned and designed so that the corner areas between the Lateral surfaces and the profile-forming lateral surface extensions formed as spherical surface segment-shaped surface areas are.

Depending on the material of a board and a desired / preferred Bump type on edges / edges can be different Types of joining applied and in connection with the invention are used, for example a thermal Joining by welding, pressure welding, soldering, etc. in certain Cases also by gluing or - at least theoretically, although it's in connection with making containers is not useful and expedient according to the invention, by screwing using stud welding devices, etc. applied threaded bolt. As a result of a joining process is also spoken of a butt joint or a butt seam.

Since folding benches as well as devices for bending and swivel bending etc. have limited dimensions, need larger containers can be assembled from several container parts. Here, according to the invention, each container part is in principle made and manufactured in the same way as a A container according to claim 1.

Such a container part is in accordance with a preferred embodiment the invention each consisting of three contiguous a jacket surface forming a rectangular surface unit, of which the two outer under right, blunt, if necessary even at an acute angle to one of at least molded on a lateral surface extension, as the floor / rear wall serving container surface are formed, and from one on the free end areas of the lateral surfaces provided lateral surface extensions by forming, adapting and / or joining molded, protruding into the interior of the respective container part, circumferential recording profile.

To complete a larger container, two equally sized container parts along the end edges of the receiving profile and along edges at the middle Shell surface opposite openings by joining firmly connected with each other. Even with one of two container parts composite container is the opening if necessary, along which the protruding inside the two container parts Recording profile is molded, again by means of a lid or flap-shaped cover part closable.

If even larger containers are required, you can choose between the two container parts described above at least one out of three connected a rectangular area unit Forming intermediate surfaces formed intermediate container part are inserted, the two outer lateral surfaces of which middle surface are molded so that the (Side) openings of the intermediate container part the same Have dimensions like the openings of the two container parts. To get a closed recording profile, the molded receiving profiles of the intermediate container part exactly correspond to the mounting profiles of the two outer container parts.

According to the invention, containers can be designed in a very variable manner different size 'with one compared to the conventional methods low labor and cost getting produced. On top of that are compared to the conventional ones Manufacturing methods in those made according to the invention Container lengths are considerably shorter, which in particular is due to the fact that the largely arbitrary customizable mounting profiles for seals or Connection profiles already at the end areas of the lateral surfaces are molded, and not additionally attached and / or cumbersome to use.

Another particularly noteworthy advantage of the various Embodiments of very different sizes executable container is that in the openings of the Container protruding receiving profiles or profile sections are already formed and only in the corner or edge areas still need to be adjusted. Here too are the ones to be made Compound lengths compared to conventional manufacturing methods considerably shorter and are generally in easily accessible places.

With regard to the requirements already mentioned hygiene when using the containers, for example in connection with medical technical devices, in the catering sector, also for household appliances and the like critical areas of application are those according to the invention executed containers the transition areas between the individual lateral surfaces with each other and / or between the lateral surfaces and the respective floor / rear surfaces or container sub-areas and the transition areas the receiving profiles as curved surface areas and / or in the transition areas to the floor or rear surface areas or an admission profile or admission profile sections in the respective "corner areas" as essentially spherical surface segment-shaped surface areas executed.

In this case, in particular, the curved areas, in a certain Scope also the substantially spherical surface segment-shaped Areas of even or changing radii have the order of a multiple of Thickness of the formable material boards are. Hence can the aforementioned transition areas between the individual Surfaces without difficulty with appropriate cleaning agents to be cleaned or treated without in particular in the corners and / or in areas where the sides and Floor surfaces collide at right angles, contamination fix that often only with special equipment and eliminated with great care and time consuming can be.

Furthermore, according to the invention, the channels of receiving profiles in the "corner areas" with appropriately dimensioned radii be executed. Thus are carried out according to the invention Container not only in connection with, as already mentioned medical technical devices and household appliances as well in gastronomy, but also in connection with refrigeration, heating and / or air conditioning apparatus, yes even can be used in frame construction and related areas.

in addition to the container parts shown in FIG. 3a, an intermediate container part which can be inserted between them;

1 shows a block-shaped container 1, designated in its entirety by 1, in a schematic perspective illustration, and the corresponding processing is shown in FIG. 1b. As can also be seen from the development in FIG. 1b, the container 1 has a total of four lateral surfaces, namely three self-contained lateral surfaces 10 ₁ to 10 ₃ and a fourth lateral surface formed from two lateral surface halves 10 ₄₁ and 10 ₄₂ .

The two lateral surface halves 10 ₄₁ and 10 ₄₂ are, as shown in FIG. 1a, joined along their longitudinal edge 4 _1b . Of course, the fourth area does not need to be composed of two halves of the same size, but can just as well consist of two unequal areas. Appropriately, however, a divided surface, here the fourth surface should be divided so that the joining process does not have to be carried out in the transition area between two outer surfaces.

The parallelepiped-shaped container 1 has a self-contained surface composed of lateral surface extensions 11 ₁ and 11 ₂ (FIG. 1b) by joining. On the longitudinal side of the development 100 opposite the lateral surface extensions 11 ₁ and 11 ₂ , further lateral surface extensions 11 _{3 are} provided, between each of which cutouts 101 are formed, the specific configuration and dimensioning of the spherical surface segment-shaped surface regions 7 to be formed in the "corner regions" and of the shape depends on the recording profile.

In FIG. 1b, thin lines in the area of the lateral surface extensions 11 ₃ indicate transition regions from receiving profile sections 3 ₁ to 3 ₄ (FIG. 1a) to the four lateral surfaces 10 ₁ to 10 ₄₂ , for which reason reference numerals 3 ₁ to 3 ₄ in FIG. 1b are in parentheses. The four receiving profile sections 3 ₁ to 3 ₄ schematically indicated in FIG. 1a are combined to form a receiving profile 3, which in FIG. 1a protrudes into the interior of an opening indicated by an arrow 2 on the front of the container 1.

In Figure 1a, the transition areas between the lateral surfaces 10 ₁ to 10 ₄₂ with each other, between these lateral surfaces and the bottom / rear surface or the receiving profile 3 or the receiving profile sections 3 ₁ to 3 ₄ are also indicated by thin lines, which preferably as curved Surface areas 6 are executed, which is shown more clearly, for example, in corresponding transition areas 6 in Figure 3a. The curved surface areas 6 can have a constant radius or also changing radii, which are generally of the order of magnitude of a multiple of the thickness of the deformable material blank from which the development 100 is cut out.

Furthermore, the mounting profile 3 in FIG. 1a is rounded in the transition areas between the four mounting profile sections 3 ₁ to 3 ₄ . A detailed representation of a transition of a receiving profile channel 32 which is rounded in the "corner regions" is shown in FIG. 2a. In 2a in top view Further, a transition area between the two jacket surfaces, for example, 10 ₁ and 10 ₄₂ and the molded-receiving profile 3 illustrated that is carried out substantially as a spherical surface segment-shaped surface region 7, which also more clearly, for example, in respective transition areas 7 in Fig. 3a is reproduced.

As shown in Fig.2b, a channel of a recording profile also designed as a right-angled channel 32 ' his.

The development 100 'shown in FIG. 1c differs from the development shown in FIG. 1b only in that only relatively narrow lateral surface extensions 11 _{2 are} provided on the longitudinal side of the development 100' opposite the cutouts 101. The result of this is that, unlike the container produced in FIG. 1a, the container shown from the unwinding 100 'does not have a closed rear side, but rather only an opening on the rear side which is reduced by, for example, curved and / or subsequently flat surface areas 6 formed by the lateral surface extensions 11c , while on the front, as with the container 1 in FIG. 1a, a receiving profile corresponding to the receiving profile 3 in FIG. 1a protrudes into the interior of an opening on the front of a container similar to the container 1 in FIG.

In 3a two equal and identical parts in the embodiment of container 1 ₁ are shown. Each container section 1 ₁ is composed of three lateral surfaces 10 _{20-10 22,} and provided therebetween, assembled from unspecified lateral surface projections, forming a bottom container part surface 12. In this case, are perpendicular in the embodiment of Figure 3a, the three lateral surfaces 10 _{20-10 22} to each other and aligned at right angles to the lower or bottom lateral surface 12 in FIG. 3a.

Of course, the two lateral surfaces 10 ₂₀ and 10 _{22 could also be arranged} at an acute or obtuse angle with respect to the partial container surface 12 made from lateral surface extensions if the central lateral surface 10 _{21 is} adapted accordingly. An unspecified end portions of the lateral surfaces 10 _{20-10 22} a circulating receiving profile 3 _2a is formed projecting in the illustrated embodiment, the interior of the container portion 1. ₁

Also in the container parts 1 ₁ , the transition areas between the lateral surfaces 10 ₂₀ to 10 ₂₂ , the partial container surface 12 and the molded receiving profile 3 _{2a are} curved surface areas 6, while the "corner regions" between the curved surface areas of the individual lateral surfaces 10 ₂₀ to 10 ₂₂ and the molded receiving profile 3 _{21 are formed} as substantially spherical surface segment-shaped surface areas 7. The channel profile of the recording profile 3 _2a corresponds to the rectangular profile of the channel shown in FIG. 2b.

By bonding / joining of the two container sections 1 ₁ along the respective opening 5 ₁ enclosing edges 4, a container is provided which can have, for example, in about twice the volume as the container la shown in Figure 1a.

In FIG. 3b, an intermediate container part 1 _{2 is} provided between the two container parts 1 ₁ of FIG. 3a, which is formed from three container surfaces 10 ₃₁ to 10 ₃₃ , for example, arranged at right angles to one another in the embodiment shown, with the free, also not designated in more detail End regions of the lateral surfaces 10 ₃₁ and 10 _{33 are} each molded into the interior of the intermediate container 1 ₂ protruding receiving profile sections 3 _2b .

As the schematic illustration is given in Figure 3b, the dimensions of the two lateral openings 5 ₂ correspond to the intermediate container to the corresponding openings of the container parts 5 ₁ 1 _1; Likewise, the cross sections of the receiving _profiles 3 _2a and 3 _{2b are} identical, so that a large container can be produced by joining the respective edges 4 of the container parts 1 ₁ and the intermediate container 1 ₂ .
