Description

Technical Field

[0001] This utility model relates to a pulp container. Background Technology

[0002] The current trend in the food and beverage packaging industry is to manufacture containers using paper pulp. These are called pulp-paper containers. or pulp container For example, it can be manufactured as follows. First, a paste-like paper pulp or paper slurry can be fed into a mold, which can consist of multiple molded bodies. After feeding in the pulp that completely wets the molded bodies, the water in the pulp is removed, and at the same time, the pulp is allowed to adhere to the walls and bottom of the mold. Subsequently, the mold is opened to obtain a pulp container, such as a pulp bottle.

[0003] WO 2019 / 034707 A1 relates to methods and apparatus for manufacturing containers, as well as methods and machines for filling and sealing containers. Containers are manufactured using fibrous pulp.

[0004] EP 1 285 994 A1 discloses a method for manufacturing an object formed from cellulose. The method includes a papermaking step, which includes: connecting each component to a suction channel in a papermaking mold; initiating the feeding of a cellulose slurry of a predetermined concentration into a cavity of the papermaking mold; and drawing in cellulose paste through the suction channel to form a cellulose layer on the inner surface of the papermaking mold.

[0005] The transport of pulp containers in container handling equipment presents new challenges to conveyor technology. Particularly during bulk transport and on assembly lines, pulp containers experience numerous problems due to friction, leading to container damage. In extreme cases, such damaged pulp containers cannot be delivered and are discarded, often along with the filler already inside.

[0006] The purpose of this invention is to develop an improved technology for transporting pulp containers in container processing equipment. Utility Model Content

[0007] This objective is achieved through the features of the following solution. Advantageous improvements are given in the specification.

[0008] One aspect of this disclosure relates to a pulp container. The pulp container has a container body made of pulp (such as fiber, preferably plant fiber (such as wood fiber, paper fiber, and / or hemp fiber, etc.)), water, and a binder (or composed of dried pulp). The pulp container has abrasion protection (such as abrasion body and / or abrasion layer) connected to the container body to protect the container body from contact-related abrasion.

[0009] Advantageously, the abrasion protection feature optimizes the transport of pulp containers within container handling equipment. The abrasion protection feature can, for example, protect the outer surface of the pulp container from abrasion at the bottom and / or outer side of the container. Preferably, the abrasion protection feature improves the sliding properties of the pulp container. This can, for example, make the pulp container easier to move on the conveyor surface. Alternatively, or preferably in combination with the above, the improved sliding properties can be used to allow the pulp containers to slide together during bulk transport, to prevent, for example, so-called abrasion.

[0010] In one embodiment, the abrasion protection is arranged on the bottom side of the container body. Alternatively or supplementarily, the pulp container may preferably be supported upright on the bottom surface solely by the abrasion protection. Alternatively or supplementarily, the pulp container may have a bottommost region formed by the abrasion protection. This advantageously prevents damage to the bottom of the container. Alternatively, the abrasion protection can improve the sliding properties of the pulp container, making it easier to transport, for example, especially even during dry operation. Therefore, advantageously, the abrasion protection can allow the container to include a dry-operation bottom, thus eliminating the need for belt lubrication, which is detrimental to the pulp container (which can become soaked and softened in the worst-case scenario).

[0011] In another embodiment, abrasion protection is arranged on the outer surface of the container body. Alternatively or supplementarily, the pulp container has a maximum diameter formed by the abrasion protection. This advantageously prevents or at least reduces abrasion of the pulp containers during bulk transport. Alternatively, the abrasion protection can improve the sliding properties of the pulp containers, making them easier to slide along with other pulp containers during bulk transport.

[0012] In another embodiment, the abrasion protection section is liquid-tight and / or airtight. This also advantageously protects the pulp container from external environmental influences. Alternatively or supplementarily, the abrasion protection section may contain a solid lubricant. Therefore, the abrasion protection section can advantageously improve the sliding properties of the pulp container. Alternatively or supplementarily, the abrasion protection section may be wear-resistant.

[0013] In one embodiment, the abrasion protection section has a coating, preferably a sliding coating. This allows for advantageous tempering treatment of an entire area of ​​the container body.

[0014] In another embodiment, the coating has a preferably cured wax. Alternatively, the coating can be a biopolymer coating, preferably a biopolyester coating, and particularly preferably a polyhydroxyalkanoate coating. Alternatively, the coating can be a silica coating (SiOx coating). Advantageously, the coating can thereby significantly improve the sliding properties of the pulp container, thereby reducing wear during pulp container transport. Biopolymer coatings, due to their biodegradability, can be particularly advantageously used in conjunction with a container body preferably also biodegradable and made of pulp.

[0015] In another embodiment, the coating may preferably be applied to the entire bottom (e.g., only) bottom side of the container body. Alternatively or supplementarily, the coating may preferably be applied to the entire side of the bottom section of the container body. Alternatively or supplementarily, the coating may cover the bottom section of the container body (e.g., only), which is formed by the bottom side of the container body and the side of the bottom section. Therefore, advantageously, the coating serves to counteract wear caused by the conveying elements in which the pulp container is located during transport.

[0016] In one embodiment, the abrasion protection section has at least one protective ring. This allows for advantageous surface conditioning of the circumferential area of ​​the container body. Preferably, the protective ring can be interrupted or continuous. Alternatively or supplementary, the protective ring can be a sliding ring. This advantageously improves the sliding properties of the pulp container. Alternatively or supplementary, the protective ring can comprise wood, cardboard, metal, and / or biopolymers, preferably biopolyesters, and particularly preferably polyhydroxyalkanoates. Therefore, easily separable components (such as protective rings made of metal) can advantageously promote the biodegradability, compostability, or at least recyclability of the pulp container.

[0017] In another embodiment, the at least one protective ring has a container bottom protective ring, which can be disposed on the bottom side of the container body, preferably against the outside of the bottom side or at least partially integrated into the bottom. This advantageously reduces wear on the bottom side of the pulp container and better protects the bottom side of the pulp container from external environmental influences.

[0018] In another embodiment, the at least one protective ring has at least one container side protective ring, preferably multiple container side protective rings spaced apart from each other relative to the vertical axis of the container body. Preferably, the at least one container side protective ring can be arranged on the outer side of the container body. This advantageously reduces lateral wear on pulp containers, especially during bulk container transport.

[0019] In one embodiment, the at least one container side guard ring is abutted against the exterior of the outer side. Alternatively, the at least one container side guard ring may be at least partially integrated into the wall of the container body. Alternatively, the at least one container side guard ring may be integrated into the label of the pulp container.

[0020] Another aspect of this disclosure relates to a method for conveying the disclosed pulp containers, preferably in a container handling apparatus downstream of a filling device. The method includes conveying the pulp containers, preferably vertically, by means of a preferably annular conveyor element, preferably a conveyor belt or conveyor chain. The pulp containers preferably contact the conveyor element only through abrasion protection, and the coefficient of friction (e.g., static friction or sliding friction) is preferably ≤0.3, ≤0.2, or ≤0.1. This advantageously allows the pulp containers to slide more easily on the conveyor element, thereby reducing wear on the bottom side of the pulp containers.

[0021] Alternatively, the pulp containers may preferably contact each other only through abrasion protection, with a coefficient of friction (e.g., static friction or sliding friction) preferably ≤0.3, ≤0.2, or ≤0.1. This advantageously makes it easier for the pulp containers to slide together, thereby particularly preventing or at least reducing scratches on the pulp containers.

[0022] In another embodiment, the contact surface of the preferred upper side of the pulp container of the conveying element, supported by the abrasion protection, is unlubricated, dry-lubricated, and / or additive-free. Alternatively or supplementarily, the conveying element can be operated in dry operation. The abrasion layer can advantageously eliminate the need for liquid lubrication of the contact surface. That is, particularly for the pulp container, such liquid lubrication can be problematic because the dried pulp in the container may absorb liquid lubricant or moisture from the lubricant, thereby causing, for example, the pulp container to soften.

[0023] Another aspect of this disclosure relates to a method for conveying the disclosed pulp containers, preferably in a container handling unit downstream of the filling device. The method includes conveying the pulp containers vertically during bulk transport. The pulp containers preferably contact each other only through abrasion protection, and the coefficient of friction (e.g., static friction or sliding friction) is preferably ≤0.3, ≤0.2, or ≤0.1. This advantageously allows the pulp containers to slide together more easily, thereby particularly preventing or at least reducing abrasions on the pulp containers.

[0024] Another aspect of this disclosure relates to a method for manufacturing the pulp container disclosed herein. The method includes forming a container body from pulp in a container mold (e.g., as mentioned at the beginning of this document, for example, a multi-component type). The method also includes providing a wear protection element. The wear protection element can be positioned in the container mold during the forming of the container body. This advantageously integrates the wear protection element into the container body. Alternatively, for example, the wear protection element can be attached to the container body after forming.

[0025] The techniques disclosed herein can be preferably used in transporting pulp containers in container handling equipment for the manufacture, cleaning, coating, inspection, filling, sealing, labeling, printing and / or packaging of containers for liquid media, preferably beverages or liquid foods.

[0026] For example, pulp containers can be made into bottles, jars, barrels, cardboard boxes, small glass bottles, etc.

[0027] The preferred embodiments and features of this utility model described above can be combined with each other as needed. Attached Figure Description

[0039] Figures 1 to 9 Different embodiments of pulp containers 10A-10U are shown. Pulp containers 10A-10U have a container body 12 and abrasion protection parts 14A-14U.

[0040] The container body 12 is made of pulp. Preferably, the container body 12 is substantially or entirely made of pulp. As described at the beginning of this document, the container body 12 is formed or manufactured by means of a mold using a manufacturing apparatus. The mold is preferably multi-component. Pulp can be applied to the mold wall to form the container body 12. The pulp can be a liquid, paste, or porridge-like mixture formed of fibers, preferably plant fibers (such as wood fibers, paper fibers, and / or hemp fibers), water, and adhesives (such as glue).

[0041] The container body 12 may have a container bottom, a container body, and a container opening. Preferably, the container body 12 may also have a container neck between the container body and the container opening. However, the container body 12 may also resemble the shape of a beverage can, thus having a continuous cylindrical body. This is not shown in the patent drawings. The container bottom may be generally flat or smooth. Alternatively, the bottom may have, for example, multiple protrusions or a surrounding flange. The container body may be, for example, cylindrical or prismatic, such as cubic.

[0042] The abrasion protection unit 14A-14U protects the container body 12 from contact-related abrasion. The abrasion protection unit 14A-14U is connected to the container body 12.

[0043] The wear protection sections 14A-14U can, in principle, be arranged on any section outside the container body 12, preferably on the bottom side and / or outer side of the container body 12. The wear protection sections 14A-14U are preferably liquid-tight and / or gas-tight. The wear protection sections 14A-14U may contain a solid lubricant. The wear protection sections 14A-14U may be wear-resistant.

[0044] Figures 1 to 3 Pulp containers 10A-10L are shown, wherein abrasion protection sections 14A-14L are arranged at the bottom or bottom section of the container body 12. Preferably, when these pulp containers 10A-10L are upright, they are preferably supported on a bottom surface (e.g., a conveying element of a conveying device) solely by the abrasion protection sections 14A-14L. The bottommost region of the pulp container 10A-10L or its container body 12 may be formed by the abrasion protection sections 14A-14L.

[0045] like Figure 1 and 2 As shown, the wear protection parts 14A-14H can preferably be implemented as a liquid-tight, airtight and / or wear-resistant coating, or have such a coating.

[0046] The coating is preferably a sliding coating. The coating may contain a solid lubricant. Preferably, the coating may contain a cured wax. Alternatively, the coating may be, for example, a biopolymer coating, preferably a biopolyester coating, and particularly preferably a polyhydroxyalkanoate coating. Alternatively, the coating may be a silica coating (SiOx coating).

[0047] The coating can be applied to the container body 12 after the container body 12 is manufactured by a coating device, such as by spraying, smearing or immersing in a coating bath.

[0048] The coating can be applied completely (wear protection parts 14A-14F) or partially (wear protection parts 14G and 14H) to the bottom or bottom section of the container body 12. Specifically, the coating can preferably be applied to at least one bottom side of the bottom of the container body 12. The coating can also preferably be applied to the sides of the bottom section of the container body 12 in the same way. Therefore, in general, the coating can preferably cover the bottom section of the container body 12, which is formed by the bottom side of the container body 12 and the sides of the bottom section.

[0049] With respect to the vertical axis of the container body 12, the coating may, for example, be arranged at the bottom 10% or less of the total height of the pulp containers 10A-10H or the container body 12, such as ≤9%, ≤8%, ..., ≤1%.

[0050] like Figure 2 As illustrated in the examples of wear protection sections 14G and 14H, the coating may also be applied only to at least one protrusion or the bottom end region or lower end region of the surrounding flange at the bottom of the container body 12. The coating at the lower end of at least one protrusion may be, for example, in a dotted pattern. The coating on the surrounding flange may be, for example, in annular or similarly surrounding pattern.

[0051] like Figure 3 As shown, the wear protection parts 14I to 14K can also be implemented as preferably liquid-tight, gas-tight, and / or wear-resistant container bottom protective rings, or have such protective rings. The container bottom protective ring can have any cross-sectional shape, such as circular, flat, or elongated.

[0052] The bottom protective ring of the container can be, for example, an interrupted or continuous protective ring. The bottom protective ring of the container can be implemented as a friction ring or a sliding ring that facilitates sliding on the bottom surface (such as the conveying element of a conveying device).

[0053] A bottom protective ring can be disposed on the bottom side of the container body 12. The bottom protective ring can abut against the outside of the bottom side. The bottom protective ring can be held in place, for example, by material bonding, compression fitting, and / or form fitting. Preferably, the bottom protective ring can be abutted against the bottom side or inserted (e.g., clipped) into a socket on the bottom side. Alternatively, the bottom protective ring can be semi-integrated or fully integrated into the bottom of the container body 12 and, for example, exposed towards the bottom side. The bottom protective ring can be positioned directly in the container mold during the molding of the container body 12, for example, so as to be (semi-)integrated into the bottom during the molding process. The bottom protective ring can be made of a non-pulp material. The bottom protective ring can also be manufactured, for example, directly on the bottom of the container body 12 by additive manufacturing (e.g., 3D printing).

[0054] The bottom protective ring of the container is preferably located on the outer circumferential edge of the bottom side. For example... Figure 3 As shown in the examples of wear protection parts 14G and 14H, the bottom protective ring of the container can also be arranged below the bottom surrounding flange of the container body 12.

[0055] Preferably, the abrasion protection portion 14A-14L on the bottom side of the pulp container 10A-10L serves to reduce friction between the bottom of the pulp container 10A-10L and the surface of the conveying device, or to facilitate sliding of the pulp container 10A-10L on the surface of the conveying device. This is, for example, in... Figure 4 The pulp container 10I and its abrasion protection part 14I are shown in the middle, wherein these embodiments are similarly applicable to Figures 1 to 3 All pulp containers 10A-10L (and Figure 9 Pulp containers 10S-10T).

[0056] like Figure 4 As illustrated, the pulp container 10I can stand upright on the upper contact surface 16 of the annular conveying element 18 of the conveying device 20. The conveying element 18 can be, for example, a conveyor belt or conveyor chain, such as a pad chain or a hinged belt chain.

[0057] The conveying device 20 may preferably be included in the container handling equipment. The container handling equipment may also include, for example, a filling device 22 for filling the pulp container 10I, and / or a closing device 24 for closing the pulp container 10I. Figure 4 (This is a schematic illustration).

[0058] The filling device 22 is adapted to fill the pulp container 10I with a liquid or paste-like filler. The filling device 22 can fill the pulp container 10I with beverages and food. Preferably, the filling device 22 may have multiple filling stations for filling the pulp container 10I. The multiple filling stations may be arranged, for example, around the circumference of a rotary filling device (filling turntable). Alternatively, the multiple filling stations may be arranged side-by-side in a row, and / or sequentially in a linear filling device. The conveying device 20 is preferably arranged upstream or downstream of the container in the filling device.

[0059] The sealing device 24 is adapted to seal the pulp container 10I. The sealing device 24 can, for example, use a lid, cork, crown cap, screw closure, or membrane to seal the pulp container 10I. The sealing device 24 may have multiple sealing stations for simultaneously or overlappingly sealing the pulp container 10I. The sealing stations may, for example, be arranged around the circumference of a rotary filling device (filling turntable). Alternatively, the multiple sealing stations may be arranged side-by-side in a row, and / or sequentially in a linear sealing device. The sealing device 24 may be arranged downstream of the container in the filling device. The conveying device 20 is preferably arranged upstream or downstream of the container in the sealing device 24.

[0060] The pulp container 10I preferably contacts the contact surface 16 only through the abrasion protection part 14I. The abrasion protection part 14I reduces friction between the pulp container 10I and the contact surface 16. The material pairing of the abrasion protection part 14I and the contact surface 16 or the conveying element 18 preferably has a coefficient of friction (e.g., static friction coefficient or sliding friction coefficient) of ≤0.3, ≤0.2, or ≤0.1. The conveying element 16 may, for example, be coated with a sliding coating, such as Teflon, and / or be made of plastic.

[0061] Particularly preferably, the contact surface 16 of the pulp container 10I of the conveying element 18, supported by the abrasion protection part 14I, is unlubricated, dry-lubricated, and / or additive-free. The conveying element 18 can operate in dry running mode or in a circular motion. The conveying element 18 can, for example, have a dry-lubricated conveyor belt or a dry-lubricated conveyor chain.

[0062] Figures 5 to 7 A pulp container 10M-10R is shown, wherein abrasion protection 14M-14R is arranged on the outer surface of the container body 12. The pulp container 10M-10R may have a maximum diameter formed by the abrasion protection 14M-14R. Preferably, the abrasion protection 14M-14R may protrude radially further (much) than the outer surface of the container body 12 relative to the vertical axis of the pulp container 10M-10R.

[0063] Preferably, when the pulp containers 10M-10R are upright, they preferably only come into contact with each other through the abrasion protection parts 14M-14R during bulk transport. The abrasion protection parts 14M-14R can reduce friction between the pulp containers 10M-10R during bulk transport. Through the abrasion protection parts 14M-14R, the pulp containers 10M-10R can (more easily) slide together.

[0064] like Figures 5 to 7 As shown, the wear protection part 14M-14R can preferably be implemented as a liquid-tight, gas-tight, and / or wear-resistant container side protection ring, or have such a protection ring. The container side protection ring can have any cross-sectional shape, such as circular, flat, or elongated.

[0065] Each pulp container 10N, 10P, or 10R may also include multiple container side guard rings. The container side guard rings may be spaced apart from each other relative to the vertical axis of the pulp container 10N, 10P, or 10R.

[0066] The container side guard ring can be, for example, an interrupted or continuous guard ring. The container side guard ring can also be implemented as a friction ring or a sliding ring capable of sliding along the container side guard ring of another pulp container.

[0067] The container side protection ring can also be relatively hard, or harder than the container body 12. The container side protection ring can be made of, for example, wood or cardboard. The material of the container side protection ring can, for example, have a hardness that prevents it from being abraded. This ensures that the container side protection ring will not be damaged, and, for example, will not damage the same hardness material used for the container side protection rings of other pulp containers. Alternatively, the container side protection ring can, for example, be made of a material specifically designed to abrade itself to protect the corresponding pulp container, thus becoming a so-called sacrificial ring. This abrasion will not damage the container body 12 itself and is suitable for protecting the container body 12.

[0068] Figure 5 The pulp container 10M is shown, wherein the abrasion protection part 14M has a protective ring on the side of the container. Figure 5 A pulp container 10N is also shown, wherein abrasion protection 14N has two vertically spaced container side protection rings. The container side protection rings can abut against the exterior of the outer surface of the container body 12. The container side protection rings can be fitted onto the corresponding container body 12. The container side protection rings can be connected to the outer surface of the container body 12 by compression fitting, form fitting, and / or material bonding. Preferably, the container side protection rings can be abutted or clipped onto the outer surface, for example, inserted into a socket on the outer surface. The container side protection rings can be made of a non-pulp material. The container side protection rings can also be manufactured by additive manufacturing (such as 3D printing), for example, directly on the outer surface of the container body 12.

[0069] In principle, as an alternative to the protective ring on the side of the container, a coating can also be applied to the side of the container, similar to the reference. Figure 1 and 2 Description of the coating on the bottom of the container.

[0070] Figure 6 A pulp container 10O is shown, wherein the abrasion protection part 14O has a container side protection ring. Figure 6 Pulp container 10P is also shown, wherein abrasion protection 14P has two vertically spaced-apart container side protection rings. The container side protection rings can be integrated into a preferably wraparound label 26 of the pulp containers 10O, 10P. The label 26 can, for example, be affixed, fitted, or retracted onto the outer surface of the container body 12. The label 26 is preferably rectangular. The container side protection rings can be integrated into the label 26 before or after applying the label 26.

[0071] Figure 7 A pulp container 10Q is shown, wherein the abrasion protection part 14O has a container side protection ring. Figure 7 Also shown is a pulp container 10R, wherein abrasion protection 14R has two vertically spaced container side protection rings. The container side protection rings may also be partially or fully integrated into the wall of the container body 12 and, for example, exposed outwards. The container side protection rings may, for example, be positioned directly in the container mold during the molding of the container body 12 so as to be (partially) integrated into the wall during the molding process.

[0072] Preferably, the abrasion protection portion 14M-14R on the side of the pulp container 10M-10R serves to reduce friction between the contacting pulp containers 10M-10R, or to facilitate sliding of the pulp containers 10M-10R together and / or harden the pulp containers 10M-10R at their contact points. This is, for example, in... Figure 8 The pulp container 10N and its abrasion protection part 14N are shown in the figure, wherein these embodiments are similarly applicable to Figures 5 to 7 All pulp containers 10M-10R (and Figure 9 Pulp containers 10S-10T).

[0073] like Figure 8 As illustrated, the pulp containers 10N can stand upright on the upper contact surface 16 of the annular conveying element 18 of the conveying device 20. The pulp containers 10I can contact each other or support each other during bulk transport.

[0074] The pulp containers 10N preferably contact each other only through abrasion protection parts 14N. Abrasion protection parts 14N can reduce friction between the pulp containers 10N. The material pairing of abrasion protection parts 14N and abrasion protection parts 14N preferably has a coefficient of friction (e.g., static friction coefficient or sliding friction coefficient) of ≤0.3, ≤0.2 or ≤0.1.

[0075] like Figure 9 As illustrated in the example, refer to Figures 1 to 4 The described technique can be particularly preferred with reference to Figures 5 to 8 The techniques described can be combined in any way.

[0076] For example, the abrasion protection part 14S of the pulp container 10S will protect the abrasion protection part 14N of the pulp container 10N (see...). Figure 5 The features of the wear protection part 14I of the pulp container 10I (see) Figure 3 The characteristics of ) are combined together.

[0077] The abrasion protection part 14T of the pulp container 10T is, for example, the abrasion protection part 14N of the pulp container 10N (see...). Figure 5 The features of the wear protection part 14A of the pulp container 10A (see) Figure 1 The characteristics of ) are combined together.

[0078] The abrasion protection part 14U of the pulp container 10U is, for example, the abrasion protection part 14N of the pulp container 10N (see...). Figure 5 Features of the pulp container 10A, abrasion protection part 14A (see) Figure 1 The features of the wear protection part 14I of the pulp container 10I (see) Figure 3 The characteristics of ) are combined together.

[0079] The pulp container 10S-10T can particularly advantageously contain the reference. Figure 4 and 8 The effects described are combined in reducing friction with the conveying element 18 and reducing friction between each other.

[0080] This invention is not limited to the preferred embodiments described above. Instead, numerous variations and modifications are possible, which also utilize the concepts of this invention and therefore fall within its scope of protection. All scope descriptions provided herein should be understood as disclosed, meaning that all values ​​falling within the corresponding range appear to be individually disclosed, for example, preferably also as the narrower outer boundary of the corresponding range.
