Reusable containers and regeneration processes

Description

[0001] The invention relates to an ecologically sustainable stackable reusable container made of paper fiber, plastic and / or metal as a transport container for liquids and bulk goods, in particular for paints and other liquid, pasty or pourable products, e.g. painting products, as well as a regeneration process for such a reusable container.

[0002] Transportable containers in various designs for filling and transporting liquid paints are known from the prior art. These are usually bucket-shaped. There are round containers, typically cylindrical ones used for paints. However, oval, rectangular, or hybrid shapes are also used. Document EP 691 278 A1 describes an example of such a container.

[0003] Typically, containers are made from thermoformed sheet metal or plastic and fitted with a lid. To better meet ecological requirements and the objectives of the circular economy, cardboard containers are also becoming increasingly common. A disadvantage here is their low diffusion resistance. Some cardboard containers require an internal coating to make them liquid-proof. This coating, in turn, negatively impacts reusability and recycling. The contents, such as paint, can contaminate the coating, precluding reuse. Recycling requires the coating to be painstakingly separated from the cardboard. This complex and expensive process also negatively affects the container's price.Containers made of sheet metal or plastic are rather disadvantageous in terms of sustainability, especially regarding resource consumption, multiple use and recycling, but can be made suitable for multiple use, refilling and reuse through the process described.

[0004] A more advantageous solution for a reusable container is described, for example, in DE 10 2020 003 698 A1. The reusable container described here has a dimensionally stable outer container in which an inner layer is arranged. The outer container is made of wound-layer paper material. The inner layer is designed as a film-like insert that is held within the outer container and adheres to it. A lid is pressed in, creating a radially eccentric pressure contact with the upper edge of the inner layer. This contact secures the lid and forms a sealing surface between the lid and the layer. The inner layer and the lid are disposed of as intended after use, and the outer container can be reused multiple times to conserve resources.

[0005] Furthermore, DE 40 41 266 A1 describes a reusable container with a similar structure. In addition to the concept of a recyclable outer container, an inner container is described that is decomposable by means of UV radiation or biodegradable.

[0006] A disadvantage here is that the outer container is often damaged or soiled, preventing its full reuse multiple times. Furthermore, once opened, the reusable container is either difficult to reseal or the inner container is attached to the outer container in such a way that removing the inner container is difficult.

[0007] The object of the invention is to provide a sustainable, resource-saving, easy and cost-effective reusable container for transport and mixing, as well as to demonstrate a regeneration process for such a reusable container.

[0008] The problem is solved with respect to the reusable container by the features listed in claim 1 and with respect to the regeneration process by the features listed in claims 6 and 7. Preferred embodiments are set forth in the dependent claims.

[0009] For the purposes of the present invention, a reusable container is understood to be a container, in particular for paints and other liquid, pasty, or pourable products, which are hereinafter collectively referred to as the container contents. These include, in particular, painting or construction products, but also, for example, oils, fats, or fertilizers.

[0010] The reusable container according to the invention comprises as essential components a container base body, a mold insert, an adhesive ring, a banderole and a lid.

[0011] The container body has a hollow, e.g., hollow cylindrical, shell and a base and is made of a paper fiber material, plastic material, and / or metal material. The material can be supplied, in particular, as wound material or by fiber casting, injection molding, or paper blister molding processes. The container body constitutes the space-defining and stability-providing structure. It forms the shape of the container and absorbs the forces exerted by the container contents as well as external forces. The size and properties of the container body also define the volume and mass of the container contents. "Hollow cylindrical" in the context of the present invention is not to be understood in a strictly geometric sense. The shape of the container body is preferably slightly conical, oval-conical, and / or angular, opening upwards, without being limited to these shapes.The bottom of the container body is closed off by a base plate, which is preferably clamped, glued, and / or pressed into the main body shell. The main body shell and base plate can also be sections of a monolithic container body.

[0012] The mold insert is made of a dimensionally stable plastic film material. This lines the inside of the container body. For this purpose, the mold insert has a container-shaped main section that is positioned within the container body.

[0013] Together with the container base, a multi-layered wall structure is formed. The container-shaped main section creates a liquid-tight and diffusion-proof layer, while the outer cardboard, plastic, and / or metal container provides the container's stable form. The container-shaped main section, with a corresponding shape and size, is inserted into the container base without needing to be bonded to it at the contact surface. The advantage is that there is no need to separate the two different materials; the molded insert can simply be removed, thus achieving high recyclability and reusability.

[0014] In particular, the plastic film can be adapted to the inner shape of the container body during the production of the mold insert by means of a thermally guided deep drawing process, which leads to easier assembly.

[0015] Furthermore, the mold insert features an overlapping section that extends over the hollow base body shell at a section of the shell's edge. The mold insert can thus be inserted into the base body up to this overlapping section. The overlapping section then conforms to the upper edge of the base body, and the container is completely lined. In addition, the shell's edge section, as well as any molded area for the lid, is covered on the outside and therefore protected from contamination, especially from paint, in this critical area.

[0016] The adhesive ring is, for example, located on the outside of an over-fold.

[0017] Preferably, this is a double-sided adhesive tape or a hot-melt adhesive. Alternatively, the adhesive ring can also be provided on the banderole as adhesive tape or a strip-shaped adhesive coating, or as a hot-melt adhesive, so that in this variant the arrangement on the outer edge of the fold only takes place when the banderole is attached.

[0018] The band is arranged circumferentially on one outer surface of the casing. It encloses the hollow casing on the outer surface as well as the overlapping section. The band rests on the adhesive ring, forming a continuous contact adhesive seam with it. Thus, it is bonded to the adhesive ring. This continuous contact adhesive seam also acts as a capillary barrier, preventing liquid contents, such as paint, from seeping behind the band. Furthermore, it features an axially extending band adhesive seam that seals the band into a casing that surrounds and covers the outer surface of the casing. Advantageously, the band serves both as a protective barrier against contamination for the casing and as a carrier for product marking, similar to a label.The band is not glued to the container body, but its position relative to the mold insert is fixed by means of the circumferential contact adhesive seam. Advantageously, with a slightly conical shape of the container body, axial upward displacement of the band is prevented, so that the mold insert is also indirectly secured against axial upward displacement via the contact adhesive seam.

[0019] This can be used in conjunction with a protective band for the outer casing and associated base protection (contamination protection), as well as extended impact and / or contamination protection, as a combination protection measure using a special sustainable paper fiber molded part, made from, for example, paper blisters, paper fiber molding, paper injection molding and / or other paper fiber technologies, possibly in conjunction with a buffer zone through a special cross-sectional shape. The buffer zone can form the geometric shape of the paper fiber molded part.

[0020] The combination of dirt protection and shock protection makes it possible to optimally protect the secondary packaging and thus enable multiple uses without damage to standard plastic and metal containers.

[0021] The base protector can be created using a click and / or snap-in system thanks to a special technical design on the inner edge of the base protector. By pressing the plastic and / or metal container, e.g., a sheet metal container, into the base protector, it is mounted without adhesive and can therefore be easily removed again.

[0022] If necessary, depending on the type of application, a version without floor protection is also conceivable.

[0023] Bonding the band to another replacement component, and only in the area of ​​the folded edge, significantly simplifies the separation of the components during recycling. After the adhesive seal is broken, both the band and the mold insert can be easily removed. Furthermore, due to the low adhesive forces, which serve only for fixation, this allows for the automation of component separation, for example using an industrial robot, thus considerably streamlining the process.

[0024] The following application options are also possible for protecting the outer shell, with or without floor protection. The bonding process is also carried out in the area described above. 1. A plastic mold liner (mold insert) in a product-specific thickness defined according to the application, in the same shape as the respective container, in the area of ​​the outer surface of the respective plastic or metal container. 2. As an alternative to the ecological grass paper band, a plastic band. 3. A molded part in the same shape made of paper injection molding or paper fiber molding, or similar manufacturing processes, including or without bottom protection.

[0025] Thus, all application examples for paper, plastic and metal containers follow the same basic idea.

[0026] Examples of construction types are shown below: Type 1 (Plastic Container): By fully bonding the paper band in the area of ​​the Formliner border with any attached flexible plastic section that adheres directly to the projecting outer edge of the plastic container through adhesion (e.g., adhesive film or equivalent), or the plastic bag system as an overlap, the outer surface in the area of ​​the projecting lid is fully protected. This protects the container edge from contamination and serves as an adhesive surface for both the band and the Formliner, thus providing combined protection. This self-adhesive plastic section extends directly under this projection, allowing the band and the Formliner to adhere through an overlapping effect without the adhesive coming into contact with the outer surface of the plastic container. Therefore, the secondary packaging remains completely clean and free of adhesive residue.This makes it possible to separate all types of materials separately during the refilling process. Design 2 (metal containers): This is achieved by fully bonding the paper or plastic band in the area of ​​the Formliner border, as already described. This principle is then applied to standard metal containers.

[0027] This allows standard plastic / metal containers to be integrated into a circular economy. This enables trouble-free refilling through comprehensive protection of these container types.

[0028] The lid features a dimensionally stable lid base and a lid molding film. This design is also intended for use with plastic and / or metal containers. The dimensionally stable lid base is the structure that provides shape and stability to the lid and has a circumferential axial groove around the edge. The lid base is preferably made of the same material as the container base: a paper blister, molded paper fiber, or another paper fiber material. Plastics, for example, recycled plastics, are also a possible material. The lid design for the cardboard container is described here as an example.

[0029] A lid form sheet, corresponding to the shape of the lid base, is assigned to the lid base and is arranged on the inside of the lid base. The lid form sheet is preferably spot-glued to the inside of the lid base or fixed by adhesive forces and serves as a contamination protection for the lid base (e.g., plastic and metal), and for the cardboard container, for example, as a contamination and / or diffusion barrier. The lid base, made of paper fiber and / or injection-molded paper, preferably has an impregnation and is thus moisture-repellent.

[0030] The reusable container is designed for a closed state as described below.

[0031] In the closed position, the lid is placed on the hollow base body. The lid not only securely seals the container but also stabilizes it, allowing for safe stacking during transport. In the closed position, the axial groove on the lid base overlaps the edge of the base body. Between the axial groove and the edge of the base body, the lid's molded film is pressed tightly against the mold insert. The sealing surface is thus advantageously formed directly between the lid's molded film and the mold insert. This creates a liquid- and airtight seal. Leakage of the container's contents is prevented, and the contents can be stored for extended periods without any loss of quality.

[0032] The container base and lid base, as well as the connection between these two components, are designed to be so robust that they can withstand the massive acceleration and centrifugal forces encountered during mixing with biaxial and centrifugal shakers. Furthermore, the container base, in conjunction with the mold insert, is designed to allow mixing to be carried out using a standard electric hand mixer.

[0033] The reusable container according to the invention is characterized by components of different recycling categories.

[0034] The container base and lid base are designed as reusable components.

[0035] The mold insert, adhesive ring, band, and lid mold film are designed as replaceable components that are detachably connected to the reusable components. Categorizing them as replaceable components does not necessarily mean that they must be replaced after every use. For example, the mold insert can be reused if it is lined with an adhesive film.

[0036] The multiple reusability of the two basic bodies as reusable components saves natural resources and reduces packaging costs for the products considered as container contents.

[0037] A surprisingly advantageous solution was found that, using simple means, allowed the functional requirements for the components during use and the functional requirements for sustainable product design to be aligned. The recycled components provide the structure that creates space and stability, but do not need to meet any special requirements regarding liquid and diffusion tightness and can therefore be provided cost-effectively. The replacement components are largely free from the requirement of dimensional stability and can thus be provided with significant material savings, which is particularly advantageous due to the single-use nature of the replacement components.

[0038] Furthermore, the replaceable components provide comprehensive protection for the recyclable components, thus enabling a high number of reuse cycles. Specifically, the container body is encased both internally and externally. Additionally, any soiling of the outer shell is covered by a new replacement band during reuse. A further advantage is that new product labeling is required for each reuse anyway, and the band eliminates the need for additional labeling. Moreover, the band can be printed before being applied.

[0039] The ability to replace only part of the reusable container to restore its reusability also allows for the proper disposal of materials. Furthermore, the ease of separation and reassembly enables process automation, which also has a positive impact on the cost of the reusable container.

[0040] In special applications, it is also possible to clean the mold insert by a washing process, preferably filtering and reusing the wastewater from the washing process.

[0041] According to an advantageous further development, the reusable container is characterized in that the mold insert has a lining and removable adhesive film on at least the main section of an inner surface of the mold insert.

[0042] After use and emptying of the container's contents, the adhesive film can be removed. Thanks to the adhesive film, the mold insert, which is a replaceable component, can also be reused for a second filling. Therefore, the mold insert only needs to be replaced every second time the reusable container is used. This further improves environmental compatibility. In the industrial production of the mold insert, a material with an adhesive film coating is preferably used.

[0043] In a further advantageous development, the reusable container is characterized by the fact that a base molding made of paper fiber material with an impregnation is arranged on the outside of the base body and that the base molding and the lid base body have corresponding surface shapes.

[0044] The durable base component, attached externally to the bottom of the container, provides additional mechanical and moisture protection. For plastic and / or metal containers, this base component serves, for example, as a dirt guard and / or impact protection element.

[0045] The base and lid each have a surface texture that corresponds to each other. "Corresponding" means that both the base and lid have sections that interlock when stacked, thus providing effective protection during transport. These surface textures can be, for example, beads or other embossings with convex or concave shapes. The base is preferably designed as a negative of the lid's surface. The base and lid preferably interact in a grid-like fashion, similar to a grid base and lid. The base can also serve solely as a dirt and / or impact protection feature.

[0046] After a further advantageous development, the reusable container is characterized by the fact that a natural fiber strap handle is attached to the outside of the hollow base body shell.

[0047] The natural fiber handle serves as a carrying handle for the container. This significantly improves handling during transport and use. Since it is made of natural fiber webbing, the sustainability of the reusable container is further enhanced. The band preferably features cutouts in the area where the natural fiber handle is attached to the container's body.

[0048] The natural fiber handle is preferably attached to punched recesses in the base body shell, or, for example, in the case of plastic containers, by means of an adapter piece, so that it can also be replaced when worn without damaging the base body shell and thus does not limit the number of usage cycles of the reusable container.

[0049] According to a further advantageous embodiment, the reusable container is characterized by the fact that the hollow base is made of wrapping paper. The base is impregnated with beeswax. This prevents the base from becoming soggy and rendering the entire packaging useless if it is placed on a damp surface.

[0050] Following this training, the adhesive ring is made of double-sided adhesive tape. Double-sided adhesive tape is readily available and therefore significantly reduces the production costs for the reusable container. However, a hot melt adhesive or similar material can also be used.

[0051] In this training course, the band is made of grass paper, for example, and features cutouts for the natural fiber strap handle. The band also serves as a space for individual printing on the container. This allows the container to be adapted to the respective sales companies and the color of the product inside. Consequently, the packaging markings can be easily replaced during the reuse process.

[0052] Another aspect of the invention relates to a regeneration process for a reusable container, which, by extension, also applies to plastic and metal containers, and is designed as described. The description of the device according to the invention applies accordingly to the method according to the invention, including the following aspects.

[0053] The regeneration process comprises the following steps: a) Loosen and remove the lid molding film b) Insert a new lid molding film c) Peel off and remove the adhesive film d) Peel off and remove the banderole, and if necessary, also the base (e.g., dirt and / or impact protection for plastic and / or metal containers) e) Apply a new banderole to the outside of the casing and create a new adhesive bond using a new contact adhesive seam and a new axially extended banderole adhesive seam

[0054] After use and complete emptying of the container contents, in process step a) the lid molding film, which is usually contaminated with traces of paint, is detached from the lid base, and subsequently, in process step b), a new lid molding film is inserted. Furthermore, in process step c), the adhesive film, which is also contaminated with traces of paint, is removed. In process step d), the banderole is peeled off, and in process step e), a new banderole is applied to the outer surface of the casing, a new adhesive bond is created using a new contact adhesive seam, and a new axially extended banderole adhesive seam is created.

[0055] Following this recycling process, hereinafter referred to as partial recycling, all color contaminants on the surfaces in contact with the container contents are removed and the reusable container can be reused.

[0056] Another aspect of the invention relates to a further regeneration process for a reusable container, which is designed as described. The description of the device according to the invention also applies accordingly to this method according to the invention, including the following aspects. The regeneration process comprises the following process steps: a) Detach and remove the lid mold film b) Insert a new lid mold film d) Peel off and remove the band d1) Detach and remove the mold insert and the adhesive ring d2) Insert a new mold insert into the container body and position a new overlap section on the hollow base body at the shell edge section and arrange a new adhesive ring e) Arrange a new band on the outside of the shell and create a new adhesive bond by means of a new contact adhesive seam and create a new axially extended band adhesive seam

[0057] This further regeneration process is also referred to below as the comprehensive regeneration process. It differs from the partial regeneration process by the additional process steps d1) and d2) and by the omission of process step c). In this process, all replacement components are separated from the recycled components and replaced with new replacement components. The result is a fully regenerated reusable container. Material usage is higher than in a partial regeneration process. However, the advantage is that virtually all parts of the reusable container that were subject to previous use are refurbished. The comprehensive regeneration process is also advantageously feasible with both a mold insert with an adhesive film and a mold insert without an adhesive film.

[0058] It is advantageous to be able to perform the partial regeneration process and the comprehensive regeneration process in alternating sequence when using a mold insert with adhesive film.

[0059] Preferably, the base molding can also be removed and replaced with a new base molding.

[0060] Almost all requirements according to Article 10 of the EU Packaging Regulation 2025 for reusable packaging can be met by the device according to the invention: The invention is described as an embodiment by means of Fig. 1 Exploded view as oblique view (schematic) Fig. 2 Exploded view as an oblique projection with bottom molded part (schematic) explained in more detail.

[0061] In this context, identical reference symbols in different figures refer to the same features or components. These reference symbols are used in the description even if they are not shown in the figure in question.

[0062] The Fig. 1 An oblique exploded view shows the individual parts of one version of the reusable container.

[0063] This is described starting from the container body 1. This has a hollow cylindrical shell 11, which has a cylindrical outer shape on its outer surface 112. In a modified embodiment, this shape is slightly conical. In the bottom area, the shell 11 is closed with the base 12 (which is concealed here), thus forming an interior space.

[0064] A liquid- and diffusion-tight molded insert 2 made of a pre-formed plastic film is inserted into the container body 1. The main section 21 of the molded insert 2 fits completely into the container body 1 and conforms to its inner walls. For improved positioning, the molded insert has an overlapping section 22 at its upper end. This completely encloses the upper outer edge section 111 of the container body shell 11.

[0065] To fix the outer edge 221 of the over-fold, an adhesive ring 3 is attached, through which the over-fold section 22 is firmly attached to the outer surface 112 of the outer shell in the upper shell edge section 111, without there being direct adhesive contact with the container body.

[0066] The adhesive ring 3 serves to attach the band 4, which completely encloses the base body shell 11 on the outer surface 112 and forms a circumferential contact adhesive seam 41 with the adhesive ring 3. Furthermore, the band 4 is sealed with the axial band adhesive seam 41. The band 4 is therefore not directly bonded to the container base body 1, which facilitates a regeneration process.

[0067] In this embodiment, a natural fiber strap handle 6 is attached to the base body shell 11 in the upper third of the outer surface 112. The natural fiber strap handle is guided through punched recesses in the base body shell 11 and can therefore be easily removed and replaced if it becomes worn. The band 4 is also recessed at the overlapping areas of the natural fiber strap handle 6 for this purpose.

[0068] A lid 5 is placed on the container base 1 for stabilization and sealing. This lid consists of the lid base 51 and an attached lid molding 52, which conforms to the inner surface 512 of the lid base. To close the container base 1, the lid 5 overhangs its overlapping section 22 with its edge groove 511. This presses the lid molding 52 and the mold insert 2 directly against each other along a circumferential line at its overlapping section 22, achieving a reliable seal of the container contents.

[0069] The Fig. 2 Figure 1 shows a further embodiment of the reusable container in an oblique exploded view. This embodiment differs from the embodiment shown in Figure 2. Fig. 1 Furthermore, a base form 7 is attached. The base form 7 is attached to the base body 12 from below by means of adhesive points.

[0070] How Fig. 2As further shown, the base component 7, viewed from below, has a cross-shaped groove that corresponds to a cross-shaped rib on the lid body 52, viewed from above. When two identical reusable containers are stacked on top of each other, the shapes of the base component 7 and the lid body 52 interlock, allowing them to be stacked securely against displacement and rotation. Since the lid body 52 has the same shape on its inner surface 512 – here as a negative of the lid body's upper surface – the lid foil 52 is also shaped identically to the base component 7.
