Description

Lid for a container

TECHNICAL FIELD The present invention relates to a lid for a container according to the preamble of claim 1.

STATE OF THE ART

For example, in the field of plastics processing, lids for bulk containers, e.g. Octagonal, rectangular or round containers, known. Commercially available lids for such containers are usually made of corrugated cardboard and are designed such that they are continuously closed on the lid surface and provided with glued short side elements.

These covers are usually used once or only a few times, dirty and damage easily and are thus quickly unusable. They only have the function of closing the container and possibly holding or supporting its side walls in the form. In particular, they are not suitable for guiding or holding commercially available granulate suction tubes through the lid.

For example, heavy, high strength octabin lids for special stackable plastic octabins are also offered which are relatively expensive, heavy, and also not designed to guide suction tubes through the lid. Significantly disadvantageous in the prior art, the lid is that these covers can not accommodate suction tubes, quickly pollute and are very bulky and thus difficult to handle. In the case of a corrugated cardboard lid they are still easy to damage and not durable.

In order to be able to perform a filling or emptying of the container, the known lid must be completely removed or placed ter to form a through-slot on the container, so that a suction tube is inserted.

As a result, inter alia, the following disadvantages in use: In the partial edition of the lid to form a through slot or with the lid removed, the bulk material from pollution is worse or not protected. In particular, in the case of high-quality, statically charged and / or transparent plastic granules and / or those for demanding applications, contamination of the granulate or bulk material, however, must be avoided at all costs. Due to, for example, the most varied types of granules in plastics processing and often extensive dust development, the bulk materials in the container must be well protected. The contamination of the bulk material otherwise leads to unacceptable additional costs during further processing.

Many plastic granules and powders (for example, cereals / flour in bakeries) are also used only partially closed lid due to the ambient conditions moisture from the air, resulting in additional post-drying and considerable energy costs. The weather-related environment variables are a major problem here.

Furthermore, with the suction tube simply plugged in, it can be used for off-center displacement of the suction tube and thus for inhomogeneous evacuation, e.g. in the case of granulate mixtures with color batch particles or recyclates, which as a rule are distributed inhomogeneously in the container. The suction pipe can change its own weight and its position with increasing emptying because it "floats" in the granulate, which can lead to an uneven emptying process, with consequent increased control and intervention effort A slipping suction tube can push the lid away, which in turn can lead to increased contamination of the bulk material, or jam and / or only suck in air.

Rigid slip covers require a lot of space and can be dirty on the unprotected inside surfaces. THE INVENTION

The invention is therefore based on the object to provide a lid for containers of the type mentioned, which does not have the disadvantages mentioned above.

This object is achieved by a container having the features of claim 1 and a container having the features of claim 18, advantageous embodiments can be found in the subclaims.

According to the invention, the lid is foldable. For this purpose, it comprises a first cover element and at least one second cover element which is connected to a first side of the first cover element and foldable relative to the first cover element, or preferably two second cover elements connected to the first cover element on opposite first sides of the first cover element and foldable relative to the first cover element. This allows the lid to be folded and stowed when not in use. This creates on the one hand

Space during storage, on the other hand is prevented by the folding that at least the container in the position of use facing underside of the lid is spared contamination.

It is preferably provided that the second cover elements are foldable under or over the first cover element, and the second cover elements in particular each have an equal or smaller surface area than the first cover element. The foldable page element can hereby at less than 99.9%, more preferably less than 90%, more preferably less than 75% and at least 25%, more preferably at least 50%, more preferably at least 70% of the length of the lid member. In this way, a particularly compact folding of the lid with an optimized (minimized) space is created.

According to an advantageous embodiment, it is provided that a first side element, which is foldable in relation thereto, is provided at least on a second side of the cover element which is different from the first side of the cover element. Preferably, this side element is designed so that it can be attached to the container wall and thus exerts a fastening function. For this purpose, it can be provided, in particular, that the at least one first side element is designed with connecting means for connecting the side element to the container to be covered. This is particularly advantageous when the lid is combined with a tube for filling or emptying. The side elements also serve to stabilize the entire lid system.

In order to improve the attachment of the lid to the container, it is preferably provided that second side elements which are foldable on the second lid elements are connected via one or more fold edges and / or hinges and / or film hinges. These second side elements can in turn be provided with connecting means to fix them to the container wall. In general, bonding agents such as adhesives, hook-and-loop fasteners or other connecting agents such as For example, magnets, snap fasteners, hooks, eyes, tabs or straps.

Preferably, it is further provided that for the optimized storage position the second cover elements and in particular the first side element are placed in a transport or storage position with its inner surface on the cover element.

A further preferred embodiment of the present invention provides that the cover element has at least one connection opening for filling or emptying. Also, a plurality of such openings may be provided to allow about the emptying of the container into several production lines. The at least one opening is preferably round and preferably has a diameter of 76 to 36 cm, preferably less than 20 cm, more preferably less than 10 cm and even more preferably less than 5 cm. In particular, a suction tube or a hose or the like can be inserted into the connection opening. Preferably, the connection opening on a molding of plastic and / or metal and / or natural materials. This molding serves as an adapter for attaching the suction pipe or the like. The named plastic or metal moldings which form and / or frame and / or stiffen the at least one push-through opening can have different inner and outer diameters, and / or with different guide elements, and / or different lengths of the guide. tion elements, preferably be designed as a pipe socket.

The molded part is preferably formed with at least one through opening and either sealing or largely sealing the einzusteckenden suction tube, wherein the lid and / or the molded part can have additional Zuluftöffnungen or columns or air-permeable devices with drying means for pressure equalization. Alternatively or additionally, the molded part may not be designed to be sealing to the suction pipe in order to allow secondary air for pressure equalization.

Preferably, the at least one connection opening or the adapter is designed such that it extends the at least one inserted suction tube with the tube longitudinal axis at an angle to the lid surface. Preferably, this angle can be 90 °, but it is also possible that the angle is preferably more than 75 °, more preferably more than 45 ° and even more preferably more than 30 ° and / or 30 °. The holder of the suction tube is thus either 90 ° degrees to the lid but also executed in different variants with different inclinations and thus allows optimal emptying of the container. The inclinations are preferably carried out in fixed units and / or also variably rotatable in smaller steps and are fixed by means of locking elements.

The connection opening can be arranged substantially centrally, in particular, on the cover element. In this way It is achieved that when the intake manifold is introduced, a displacement of the cover due to asymmetrical introduction of force via the intake manifold is avoided. But also an eccentric arrangement is conceivable, for example, to provide a balance, if the container is to be stored approximately on an inclined plane. The molded part with the connection opening can for example be inserted into two parallel running guide rails which are attached to the cover, so that it can be removed for folding the cover.

It can preferably be provided that the connection opening is configured with a pierceable elastomer unit and / or a closure element. The connection opening, which is preferably designed as a through opening, may be self-closing with sealing lips and / or rubber sleeves and / or elastic valves. In this way it is ensured that the passage of contaminants through the lid is avoided in the interior of the container. Also, the lid can be protected in the folded state against contamination during storage.

If according to the invention of suction tube or connecting pipe is mentioned, this is not exclusively a pipe meant, but it may also be a hose or another form of bulk material. Also, not only must be sucked on the suction pipe to empty the container, but this can also be provided for filling the container. Said molding is formed according to an advantageous embodiment to at least one side of the lid member flat. The molding is preferably 5 cm or less, preferably 3 cm or less, in particular less than 2 cm, more preferably less than 1 cm, more preferably less than 5 mm, over the surface of the cover element.

In order to simplify the attachment of the connection pipe to the lid, provision can be made, in particular, for the molding to have at least one guide element and / or at least one holding element for at least one connection pipe or suction pipe.

The lid according to the invention may be made of compact plates and / or web plates and / or multilayer plates and / or lightweight panels made of commercially available compact and / or foamed plastics (for example PP, PE, PUR, PVC or the like) or corrugated board or organo sheets or fiber composite materials. Also combinations of these are possible.

Also, the use of commercially available wood and / or building boards and / or composite panels and / or aluminum plates may be advantageous in special applications as a material for the lid. Furthermore, the lid material may be antistatic to reduce dust buildup. Preference is also given to at least impregnated and / or lacquered and / or plastic-film and / or plastic-fabric-laminated panels and / or boards as well as natural fiber materials. For better durability, wiping and cost reasons are outer layers and / or films of commercially available plastics (homopolymers or copolymers) in particular polypropylene (PP), polyethylene (PE), polyurethane (PUR) and polyvinyl chloride (PVC) and / or coated therewith fabric and / or textiles preferred.

For special applications, which depend in particular on the nature of the goods to be filled in the container, according to a further embodiment of the invention, the lid on its - the container in the use position facing - inside a moisture-absorbing device with desiccant ( eg silicates or other hygroscopic substances), preferably a replaceable desiccant unit with ventilation openings. In this way, existing interfering moisture can be absorbed in the container or in the bulk material contained therein.

Further, the lid may have a grounding device for dissipating a static charge. Thereby, the subsequent processing of the bulk material can be simplified, as this would otherwise charge due to the internal friction during emptying of the container. This is certainly avoided with the grounding. In addition, it can be provided that the lid is made in one piece. For example, it may be stamped or constructed of assembled, for example glued and / or welded, elements. Folded edges may be formed from the lidding material by embossing, punching, perforating, ultrasonic welding or embossing, and / or formed by the flexible films and / or textile materials or fabrics joining the foldable elements. These connecting materials can be welded onto the cover material and / or adhesively bonded and / or also formed via film hinges or double / multiple folds directly by plastic connections.

Finally, the lid may have at least one additional opening. This serves to guide measuring technology, in particular measuring probes or measuring sensors or venting or pressure compensation devices, into the interior of the container in order to provide information about the state of the bulk material - e.g. its humidity or temperature - to get.

Amongst others, the invention offers the following advantages over previous solutions:

- During the emptying process with a suction tube, the contents of the container are reliably protected from dirt;

- By means of the insertion opening or connection opening, a suction pipe connected can be kept stable and secure, this being supported in particular by the design as a molded part, The lid can be folded very compact and is therefore stackable for transport and storage and requires little storage space. In addition, can be achieved in the folded state by folding the lid of the dirt entry during storage by the arrangement of the inner side facing lid and lid side elements;

The lid can be produced very inexpensively; The lid can be very easily fixed by means of the side elements on the container;

By at least one extended side member additionally a weighting and stiffening of the lid is achieved

The lid is suitable for attaching a desiccant to dry and clean the material stored in the container. Since ^¬ by itself can significantly reduce quality defects or Ausfallra ^¬ th of machines due to polluted by suction material, the manufacturing process is of high quality and safe.

In addition, an environmentally friendly use of the lid by an energy-saving effect (predrying hygroscopic materials), its multiple use, its space-saving design, increasing safety at work and finally minimizing the Committee in production through optimally prepared and clean material.

BEST MODE FOR CARRYING OUT THE INVENTION

The lid 100, which in the example shown is an octagonal lid with eight corners, comprises a first lid element 1, which has at its, the opposite long first sides 11, 12 connected via a folding edge second lid elements la. In the present example, two second cover elements are shown, but it is also possible to provide only a second cover element. The other versions therefore apply accordingly for only a second cover element accordingly. At the likewise opposite, short second sides 13, 14 of the cover element 1, in the example shown, two almost equally long side elements 2 are likewise connected via one folding edge each.

At least one connection or insertion opening 4 is preferably arranged centrally on the first cover element 1 and formed with a flat side upwards. It can also be provided a plurality of openings 4, as the embodiment of Figure 4 shows. Also, the side parts 2, 3, 3a may be of different lengths (long refers to the direction from the folding edge to the respective cover element 1, la away) or - as shown in Figure 4 - the same length. Preferably, the first side parts 2 (of which only one may be provided) longer than the second side parts 3, 3a, preferably at least twice as long. On the second cover elements 1a, further folding elements 30, 30a (in the example shown three for every second cover element 1a) side elements 3 and 3a are connected. The second cover elements 1a can be placed with their inner surface on the cover element 1 for protection against soiling, in particular during transport or storage, while folding in the second side elements 3, 3a. The folded state of the container is shown in particular in FIGS. 2B and 3.

The long first side elements 2 in this exemplary embodiment do not quite have the length of the cover element 1, so that they are folded onto the second side elements 1a. you can. The connecting or insertion opening 4 is enclosed by a molded part 7, 7a (compare FIGS. 2A, 2B, 3) with a preferably variable inner diameter. The connection or insertion opening 4 preferably has a sealing means 4a.

The molded part 7, 7a, which protrudes on one side of the lid - elements 1, has a holding plate 7, with which it is attached to the lid or integrally connected thereto. Next, the molding preferably has a connected to the support plate 7 adapter or Rohrstutzten 7a, in which a suction tube or the like on or can be plugged. The molding 7, 7a may e.g. a two-part irreversibly or reversibly zusammenschnapp- ble component made of plastic and / or metal with a connected via a film hinge closure cap for the pipe socket 7a of the plastic molding or a rubber sleeve. The retaining plate 7 can be inserted into corresponding guides attached to the cover 100.

Furthermore, a drying means 5, preferably designed as an inlay, can be provided on the underside (facing the container) of the lid 100 in order to remove moisture from the bulk material in the container or to absorb it. At the same time, the inlay or the inlay receiving device can also serve to fix the lid and as a spacer or as a stiffener to possibly stiffen the container with increasing emptying. The attachment of the lid 100 to the container 200 is preferably done as follows:

The (still) folded lid 100 for container 200, such as octabins, can be placed on the filled container 200 on the container bottom 202 facing away from the front side of the container wall 201. Then, the long side members 2 are unfolded, as are the second lid members la and the second side members 3, 3a. All side elements 2, 3, 3a can be placed externally on the container wall 201 and, if necessary, firmly but detachably connected thereto, as shown in FIGS. 2A and 4. The connecting or insertion opening 4 is now accessible in the lid 100 that has been unfolded such that a suction tube can be inserted into the container 100 for emptying.
