Description

Technical area

The invention relates to a pulp container, methods for conveying pulp containers and a method for producing a pulp container.

Technical background

A current development trend in the food and beverage packaging industry is the production of containers from pulp. These so-called paper pulp containers or pulp containers can be manufactured, for example, as follows. First, a pasty paper pulp or pulp can be introduced into a mold, which can consist of several shaped bodies. After introducing the pulp, which fully wets the moldings, the water is removed from the pulp and at the same time it is ensured that the pulp adheres to the walls and bottom of the mold. The mold is then opened and a pulp container is obtained, e.g. B. a pulp bottle.

The WO 2019/034707 A1 relates to a method and a device for producing a container and a method and a machine for filling and closing the container. A pulp containing fibers is used to produce the containers.

The EP 1 285 994 A1 discloses a method of making a pulp molded article. The method includes a papermaking step that includes connecting each section to suction channels in a papermaking mold, starting to feed a pulp slurry at a predetermined concentration into the cavity of the papermaking mold, and sucking the pulp slurry through the suction channels to form a pulp layer on the inner surface of the papermaking mold To form papermaking mold.

The transport of pulp containers in a container treatment plant poses new challenges for conveyor technology. Particularly during mass transportation and conveyor belt transportation, pulp containers experience many problems due to friction, which result in the pulp containers being damaged. In extreme cases, pulp containers damaged in this way cannot be delivered and are rejected, as is the content that has already been filled into them.

The invention is based on the object of developing an improved technology for transporting the pulp containers in a container treatment plant.

Summary of the invention

The task is solved by the features of the independent claims. Advantageous further developments are specified in the dependent claims and the description.

One aspect of the present disclosure relates to a pulp container. The pulp container has a container body which is made of pulp (e.g. fibers, preferably plant fiber (e.g. paper fibers, wood fibers, hemp fibers, etc.), water and a binder) (or consists of dried pulp). The pulp container has a wear protection (e.g. wear body and/or wear layer) which is connected to the container body to protect the container body from contact-related wear.

The wear protection can advantageously enable optimized transport of the pulp containers in a container treatment system. The wear protection can protect the pulp container from wear on the outside, e.g. B. on a container base and/or container outer jacket. The wear protection preferably makes it possible to improve the sliding properties of the pulp container. This can be used, for example, to make it easier to push the pulp container over a conveyor surface. Alternatively or preferably in combination, the improved sliding properties can be used to enable pulp containers to slide against each other in mass transport, for example to prevent so-called scuffing.

In one embodiment, the wear protection is arranged on an underside of a bottom of the container body. Alternatively or additionally, the pulp container can be supported upright, preferably only, on a surface via the wear protection. Alternatively or additionally, the pulp container can have a lowermost surface which is formed by the wear protection. This can advantageously prevent damage to the bottom of the container. Instead, the wear protection can, for example, improve the sliding properties of the pulp container, so that it can be conveyed better, especially during dry running. The wear protection can advantageously result in the container having a dry-running bottom, which means that belt lubrication, which is disadvantageous for the pulp container (pulp container can become saturated and soften in the worst case scenario), can be dispensed with.

In a further exemplary embodiment, the wear protection is arranged on an outer surface of the container body. Alternatively or additionally, the pulp container has a maximum diameter that is determined by the wear protection is formed. This can advantageously prevent or at least reduce scuffing in the mass transport of the pulp containers.

Instead, the wear protection can, for example, improve the sliding properties of the pulp container so that it can slide more easily along the other pulp containers during mass transport.

In a further exemplary embodiment, the wear protection is liquid-tight and/or gas-tight. The wear protection can thus advantageously also protect the pulp container from external environmental influences. Alternatively or additionally, the wear protection can have a solid lubricant. The wear protection can thus advantageously improve the sliding properties of the pulp container. Alternatively or additionally, the wear protection can be abrasion-resistant.

In one embodiment, the wear protection has a coating, preferably a sliding coating. In this way, an area of the container body can advantageously be coated over the entire surface.

In a further embodiment, the coating has a, preferably hardened, wax. Alternatively, the coating may be a biopolymer coating, preferably a biopolyester coating, particularly preferably a polyhydroxyalkanoate coating. Alternatively, the coating can be a silicon oxide coating (SiOx coating). In this way, the coating can advantageously significantly improve the sliding properties of the pulp container, which means that less abrasion can occur during transport of the pulp container. Due to its biodegradability, the biopolymer coating can be used particularly advantageously in conjunction with the container body made of pulp, which is preferably also biodegradable.

In a further embodiment, the coating coats (e.g. only) an underside of a bottom of the container body, preferably over the entire surface. Alternatively or additionally, the coating can coat a lateral surface of a bottom section of the container body, preferably over the entire surface. Alternatively or additionally, the coating can (e.g. only) cover a bottom section of the container body consisting of an underside of a bottom of the container body and a lateral surface of the bottom section. The coating can therefore advantageously aim in particular to counteract wear caused by a conveying element on which the pulp container stands during transport.

In one embodiment variant, the wear protection has at least one protective ring. In this way, a circumferential area of the container body can advantageously be coated over the entire surface. Preferably, the protective ring can be interrupted or continuous. Alternatively or additionally, the protective ring can be a sliding ring. This can advantageously improve the sliding properties of the pulp container. Alternatively or additionally, the protective ring can comprise wood, cardboard, metal and/or a biopolymer, preferably a biopolyester, particularly preferably a polyhydroxyalkanoate. This can advantageously support biodegradability or compostability of the pulp container or at least recyclability through easily separable parts (e.g. metal protective ring).

In a further embodiment variant, the at least one protective ring has a container base protection ring which is arranged on an underside of a base of the container body, preferably on the outside of the underside or at least partially integrated in the base. This can advantageously reduce wear on the bottom of the pulp container and the bottom of the pulp container can be better protected from environmental influences.

In a further embodiment variant, the at least one protective ring has at least one container jacket protective ring, preferably a plurality of container jacket protective rings spaced apart from one another with respect to a vertical axis of the container body. Preferably, the at least one container shell protective ring can be arranged on an outer surface of the container body. This can advantageously reduce wear on the shell side of the pulp container, particularly in container mass transport.

In one exemplary embodiment, the at least one container jacket protective ring rests on the outside of the outer jacket surface. Alternatively, the at least one container jacket protective ring can be at least partially integrated in a wall of the container body. Alternatively, the at least one container jacket protective ring can be integrated into a label of the pulp container.

Another aspect of the present disclosure relates to a method for conveying pulp containers as disclosed herein, preferably container downstream of a filling device in a container processing plant. The method involves conveying the pulp containers, preferably upright, by means of a preferably rotating conveying element, preferably a conveyor belt or conveyor chain. The pulp containers contact, preferably only, via the wear protection the conveying element, preferably with a coefficient of friction (e.g. coefficient of static friction or coefficient of sliding friction) ≤ 0.3, ≤ 0.2 or ≤ 0.1. This advantageously makes it possible for the pulp containers to slide more easily along the conveyor element, thereby reducing wear on the bottom of the pulp containers.

Optionally, the pulp containers can contact each other, preferably only, via the wear protection, preferably with a coefficient of friction (e.g. coefficient of static friction or coefficient of sliding friction) ≤ 0.3, ≤ 0.2 or ≤ 0.1. This advantageously makes it possible for the pulp containers to slide more easily along one another, whereby in particular scuffing on the pulp containers can be prevented or at least reduced.

In a further exemplary embodiment, a contact surface, preferably on the upper side, of the conveying element, on which the pulp containers are supported via the wear protection, is unlubricated, dry-lubricated and/or free of auxiliary substances. Alternatively or additionally, the conveying element can be operated in dry running. The wear layer can advantageously make it possible to dispense with liquid lubrication of the contact surface. This can be particularly problematic for pulp containers, since the dried pulp of the pulp container can absorb the liquid lubricant or the moisture from the lubricant, which could, for example, soften the pulp container.

Another aspect of the present disclosure relates to a method for conveying pulp containers as disclosed herein, preferably container downstream of a filling device in a container processing plant. The method involves conveying the pulp containers upright in mass transport. The pulp containers contact each other, preferably only, via the wear protection, preferably with a coefficient of friction (e.g. coefficient of static friction or coefficient of sliding friction) ≤ 0.3, ≤ 0.2 or ≤ 0.1. This advantageously makes it possible for the pulp containers to slide more easily along one another, whereby in particular scuffing on the pulp containers can be prevented or at least reduced.

Another aspect of the present disclosure relates to a method of making a pulp container as disclosed herein. The method includes forming the container body from pulp into a (e.g. multi-part) container shape (e.g. as mentioned at the outset herein). The method further includes providing wear protection. The wear protection can already be positioned in the container shape when the container body is being formed. In this way, integration of the wear protection into the container body can advantageously be made possible. Alternatively, the wear protection can be connected to the container body, for example after molding.

The techniques disclosed herein may preferably be used to transport the pulp containers in a container processing plant for manufacturing, cleaning, coating, testing, filling, sealing, labeling, printing and/or packaging containers for liquid media, preferably beverages or liquid foods.

For example, the pulp containers can be designed as bottles, cans, canisters, cartons, bottles, etc.

The previously described preferred embodiments and features of the invention can be combined with one another in any way.

Detailed description of exemplary embodiments

The 1 until 9 show different embodiments of a pulp container 10A-10U. The pulp container 10A-10U has a container body 12 and a wear guard 14A-14U.

The container body 12 is made of pulp. Preferably, the container body 12 is made essentially or entirely from pulp. The container body 12 can be formed or manufactured by a manufacturing device using a mold, for example as explained at the outset herein. The shape is preferably multi-part. The pulp may be applied to a wall of the mold for forming the container body 12. The pulp can be a liquid, pasty or mushy mixture of fibers, preferably plant fibers (e.g. wood fibers, paper fibers and/or hemp fibers), water and a binder, e.g. B. glue.

The container body 12 may have a container base, a container body and a container mouth. The container body 12 can preferably also have a container neck between the container body and the container mouth. The container body 12 can also have a shape similar to a beverage can and thus have a continuous cylindrical body. This is not shown graphically in the patent drawings. The container bottom can be essentially flat or planar. Alternatively, the base can have, for example, several projections or a circumferential collar. The container body can, for example, be cylindrical or prism-shaped, e.g. B. be cuboid.

The wear protection 14A-14U protects the container body 12 from contact-related wear. The wear protector 14A-14U is connected to the container body 12.

In principle, the wear protection 14A-14U can be arranged on any section on the outside of the container body 12, preferably on an underside of a base and/or an outer lateral surface of the container body 12. The wear protection 14A-14U can preferably be liquid-tight and/or gas-tight. The wear protection 14A-14U can have a solid lubricant. The wear protection 14A-14U can be abrasion resistant.

The 1 until 3 show pulp containers 10A-10L, in which the wear protection 14A-14L is arranged on a bottom or bottom portion of the container body 12. Preferably, the pulp container 10A-10L, when standing upright, is preferably only on a surface, e.g. via the wear protection 14A-14L. B. a conveying element of a conveying device. A lowermost surface of the pulp container 10A-10L or its container body 12 can be formed by the wear protection 14A-14L.

Like in the 1 and 2 is shown, the wear protection 14A-14H can preferably be designed as or have a coating that is preferably liquid-tight, gas-tight and / or abrasion-resistant.

The coating is preferably a sliding coating. The coating can have a solid lubricant. The coating can preferably have a wax, preferably hardened. Alternatively, the coating can be, for example, a biopolymer coating, preferably a biopolyester coating, particularly preferably a polyhydroxyalkanoate coating. Alternatively, the coating can be a silicon oxide coating (SiOx coating).

The coating may be applied to the container body 12 after manufacture of the container body 12 by a coating device, e.g. B. by spraying the coating, by applying the coating or by immersing it in a coating bath.

The coating can completely (wear protection 14A-14F) or partially (wear protection 14G and 14H) coat the bottom or bottom portion of the container body 12. In detail, the coating can coat at least one underside of a bottom of the container body 12, preferably over the entire surface. In addition, the coating can coat a lateral surface of a bottom section of the container body 12, preferably also over the entire surface. Overall, the coating can therefore preferably cover a bottom section of the container body 12 consisting of an underside of a bottom of the container body 12 and a lateral surface of the bottom section.

With respect to a vertical axis of the container body 12, the coating can, for example, be in the lowest 10% or less, e.g. B. ≤ 9%, ≤ 8%, ..., ≤ 1%, with respect to a total height of the pulp container 10A-10H or the container body 12 may be arranged.

It is also possible for the coating to coat, for example, only a bottom or lower end region of at least one projection or a circumferential collar on the bottom of the container body 12, as exemplified by the wear protection 14G and 14H in 2 is shown. The coating of a lower end of at least one projection can, for example, be point-shaped. The coating of a circumferential collar can, for example, be ring-shaped or also circumferential.

As in 3 is shown, the wear protection 14l to 14K can also be designed as or have a container bottom protective ring, preferably liquid-tight, gas-tight and / or abrasion-resistant. The container bottom protection ring can have any cross-sectional shape, e.g. B. round, flat or elongated.

The container bottom protective ring can be, for example, an interrupted or continuous protective ring. The container bottom protection ring can be used as a friction ring or a sliding ring to enable easy sliding over a surface, e.g. B. a conveying element of a conveying device.

The container bottom protection ring can be arranged on an underside of a bottom of the container body 12. The container bottom protection ring can rest on the outside of the bottom. For example, the container base protective ring can be held in a material-locking, non-positive and/or positive-locking manner. The container bottom protective ring can preferably be glued to the underside or inserted into a receptacle on the underside, e.g. B. clipped in. Alternatively, the container bottom protective ring can also be partially or fully integrated into the bottom of the container body 12 and, for example, be exposed towards the underside. The container bottom protective ring can, for example, be positioned in the container shape directly when the container body 12 is formed in order to be (partially) integrated into the bottom during the forming process. The container bottom guard ring may be made of a non-pulp material. It is also possible for the container bottom protective ring to be manufactured additively, e.g. B. 3D printed, e.g. B. directly to the bottom of the container body 12.

The container base protective ring is preferably arranged on an outer circumferential edge of the underside of the base. It is also possible for the container bottom protection ring to be arranged at the bottom of a circumferential collar of the bottom of the container body 12, as exemplified by the wear protection 14K and 14L in 3 is shown.

The container bottom-side wear protection 14A-14L of the pulp containers 10A-10L preferably has the task of reducing friction between the bottom of the pulp container 10A-10L and a conveyor surface or of enabling the pulp containers 10A-10L to slide easily over the conveyor surface. An example of this is in 4 based on the pulp containers 10l with their wear protection 141, the explanations being analogous for all pulp containers 10A-10L 1 until 3 (as well as the 10S-10T pulp containers 9 ) apply.

As in 4 As shown by way of example, the pulp containers 10l can stand upright on a top contact surface 16 of a rotating conveyor element 18 of a conveyor device 20. The conveying element 18 can be, for example, a conveyor belt or a conveyor chain, e.g. B. mat chain or hinged chain.

The conveying device 20 can preferably be included in a container treatment system. The container treatment system can, for example, also have a filling device 22 for filling the pulp containers 10l and / or a closing device 24 for closing the pulp containers 101 (purely schematic in 4 shown).

The filling device 22 can be designed to fill the pulp containers 10l with a liquid or pasty filling material. The filling device 22 can fill the pulp containers 10l with a drink or food. The filling device 22 can preferably have several filling stations for filling the pulp containers 101. The multiple filling stations can, for example, be arranged around the circumference of a rotary filling device (filler carousel). Alternatively, the plurality of filling stations can be arranged, for example, in a row next to one another and/or one behind the other in a linear filling device. The conveying device 20 can preferably be arranged upstream or downstream of the container from the filling device.

The closing device 24 can be designed to close the pulp containers 10l. For example, the closing device 24 can close the pulp containers 10l with a lid, a cork, a crown cap, a screw cap or a film. The closing device 24 can have several closing stations for simultaneous or overlapping closing of the pulp containers 10l. For example, the closing stations can be arranged around the circumference of a rotary closing device (sealing carousel). Alternatively, the plurality of closing stations can, for example, be arranged in a row next to one another and/or one behind the other in a linear closing device. The Closing device 24 can be arranged downstream of the container from the filling device. The conveying device 20 can preferably be arranged upstream of the container or downstream of the container 24.

The pulp containers 10l preferably contact the contact surface 16 only via the wear protection 141. The wear protection 141 can reduce friction between the pulp container 10l and the contact surface 16. The material pairing of wear protection 14l and contact surface 16 or conveying element 18 can preferably have a coefficient of friction (e.g. coefficient of static friction or coefficient of sliding friction) ≤ 0.3, ≤ 0.2 or ≤ 0.1. The conveying element 16 can, for example, be coated with a sliding coating, e.g. B. Teflon, and / or made of plastic.

Particularly preferably, the contact surface 16 of the conveying element 18, on which the pulp containers 10l are supported via the wear protection 14l, can be unlubricated, dry-lubricated and/or free of auxiliary substances. The conveying element 18 can be operated in dry running or rotate. For example, the conveying element 18 can be a dry-lubricated conveyor belt or a dry-lubricated conveyor chain.

The 5 until 7 show pulp containers 10M-10R, in which the wear protection 14M-14R is arranged on an outer surface of the container body 12. The pulp containers 10M-10R may have a maximum diameter formed by the wear guard 14M-14R. Preferably, the wear protection 14M-14R can protrude radially (significantly) further with respect to a vertical axis of the pulp container 10M-10R than an outer surface of the container body 12.

Preferably, the pulp containers 10M-10R, when standing upright, can touch each other in mass transport, preferably only via the wear protection 14M-14R. The wear guard 14M-14R can reduce friction between the pulp containers 10M-10R in bulk transportation. The pulp containers 10M-10R can slide together (easier) thanks to the wear protection 14M-14R.

Like in the 5 until 7 is shown, the wear protection 14M-14R can preferably be designed as a, preferably liquid-tight, gas-tight and / or abrasion-resistant, container jacket protective ring or have such. The container jacket protective rings can have any cross-sectional shape, e.g. B. round, flat or elongated.

There can also be several container jacket protection rings per pulp container 10N, 10P, 10R. The container shell protection rings may be spaced apart from one another with respect to a vertical axis of the pulp container 10N, 10P, 10R.

The container jacket protective ring can be, for example, an interrupted or continuous protective ring. The container jacket protective ring can be designed as a friction ring or a sliding ring to enable sliding along a container jacket protective ring of another pulp container.

It is also possible that the container jacket protective rings are comparatively hard or harder than the container body 12. The container jacket protective rings can be made of wood or cardboard, for example. For example, the material of the container jacket protective rings can be so hard that it cannot be rubbed off. This means that it is not damaged, for example, and it also does not damage the equally hard material of the container jacket protective ring of the other pulp container. Alternatively, the container jacket protective ring can, for example, be specifically made as a so-called sacrificial ring from a material that wears out and thus protects the respective pulp container. This wear does not damage the container body 12 itself and is desired to protect the container body 12.

The 5 shows a pulp container 10M, in which the wear protection 14M has a container jacket protection ring. The 5 also shows a pulp container 10N, in which the wear protection 14N has two vertically spaced container jacket protection rings. The container jacket protective rings can rest on the outside of an outer surface of the container body 12. The container jacket protective rings can be placed over the respective container body 12. The container jacket protective rings can be connected to the outer surface of the container body 12 in a force-fitting, form-fitting and/or material-locking manner. The container jacket protective ring can preferably be glued or clamped to the outer jacket surface, e.g. B. inserted in a receptacle on the outer surface. The container shell guard rings may be made of a non-pulp material. It is also possible for the container jacket protective rings to be manufactured additively, e.g. B. 3D printed, e.g. B. directly onto an outer surface of the container body 12.

In principle, it is also possible to provide a container jacket coating instead of a container jacket protective ring, analogous to the explanations for coating the container bottom with reference to 1 and 2 .

The 6 shows a pulp container 10O, in which the wear protection 140 has a container jacket protective ring. The 6 also shows a pulp container 10P, in which the wear protection 14P has two vertically spaced container jacket protection rings. The container jacket protective rings can be integrated into a preferably circumferential label 26 of the pulp container 10O, 10P. The label 26 can, for example, be glued, slipped over or shrunk onto an outer surface of the container body 12. The label 26 can preferably have a rectangular shape. The container jacket protective rings can be integrated into the label 26 before or after the label 26 is applied.

The 7 shows a pulp container 10Q, in which the wear protection 140 has a container jacket protection ring. The 7 also shows a pulp container 10R, in which the wear protection 14R has two vertically spaced container jacket protection rings. The container jacket protective rings can be partially or fully integrated in a wall of the container body 12 and, for example, be exposed to the outside. The container jacket protective rings can, for example, be positioned in the container mold directly when the container body 12 is formed in order to be (partially) integrated into the wall during the forming process.

The container shell-side wear protection 14M-14R of the pulp containers 10M-10R preferably has the task of reducing friction between pulp containers 10M-10R that come into contact with one another. or to enable the pulp containers 10M-10R to slide easily against one another and/or to harden the pulp containers 10M-10R at their contact points. An example of this is in 8th based on the pulp containers 10N with their wear protection 14N, the explanations being analogous for all pulp containers 10M-10R 5 until 7 (as well as the 10S-10T pulp containers 9 ) apply.

As in 8th As shown by way of example, the pulp containers 10N can stand upright on the top contact surface 16 of the rotating conveyor element 18 of the conveyor device 20. The pulp containers 10l can touch or support each other during mass transport.

The pulp containers 10N preferably contact each other only via the wear protection 14N. The wear protector 14N can reduce friction between the pulp containers 10N. The material pairing of wear protection 14N and wear protection 14N can preferably have a coefficient of friction (e.g. coefficient of static friction or coefficient of sliding friction) ≤ 0.3, ≤ 0.2 or ≤ 0.1.

As in 9 is shown by way of example, can be made with reference to the 1 until 4 Techniques explained are particularly preferred with those with reference to 5 until 8th The techniques explained can be combined with one another as desired.

For example, the wear protection 14S of the pulp container 10S combines the features of the wear protection 14N of the pulp container 10N (see 5 ) and the features of the wear protection 14l of the pulp container 10l (see 3 ).

The wear protection 14T of the pulp container 10T combines, for example, the features of the wear protection 14N of the pulp container 10N (see 5 ) and the features of the wear protection 14A of the pulp container 10A (see 1 ).

The wear protection 14U of the pulp container 10U combines, for example, the features of the wear protection 14N of the pulp container 10N (see 5 ), the features of the wear protection 14A of the pulp container 10A (see 1 ) and the features of the wear protection 14l of the pulp container 10l (see 3 ).

The pulp containers 10S-10T can be particularly advantageous with reference to 4 and 8th Combine the explained effects with regard to the reduced friction to the conveying element 18 and the reduced friction with one another.

The invention is not limited to the preferred embodiments described above. Rather, a large number of variants and modifications are possible, which also make use of the inventive idea and therefore fall within the scope of protection. In particular, the invention also claims protection for the subject matter and features of the subclaims, regardless of the claims referred to. In particular, the individual features of independent claim 1 are each disclosed independently of one another. In addition, the features of the subclaims are also disclosed independently of all features of independent claim 1 and, for example, independently of the features relating to the presence and / or configuration of the container body and / or the wear layer of independent claim 1. All range information herein is to be understood to be disclosed in such a way that all values falling within the respective range are disclosed individually, e.g. B. also as preferred narrower external boundaries of the respective area.
