[0001] Roll of garbage bags, method for disposing of garbage and method for providing a roll of garbage bags Description

[0002] The invention relates to a roll of garbage bags, a method for disposing of garbage, and a method for providing a roll of garbage bags.

[0003] Garbage bag rolls are a common household item. A single garbage bag can be torn off the open end of the roll, typically at a perforation or other point where the material is thinned. This thinning could be, for example, a section of plastic. Usually, a single garbage bag is torn off by hand. However, the thinning may also allow for tearing with a tool such as a knife or scissors.

[0004] Such garbage bag rolls are typically manufactured by producing individual bags separately and then folding them into sheets. These sheets are then fed via conveyor belts to a joining device, where each sheet is joined to another. Welding is a particularly suitable joining technique, for example, by melting (with heat application) and / or pressure welding (under pressure application). The material is then weakened at the joint, for example, by perforation. This creates a continuous strip of garbage bags. A strip containing the desired number of bags for the garbage bag roll is cut from this strip and wound onto it. A paper roll or similar material is then applied to the wound garbage bags to prevent them from unwinding. Other fixing methods are also possible.The individual garbage bags can have a certain level of complexity; for example, it is regularly provided that a drawstring is provided on the top of an opening of the garbage bag, which is guided in a guide and / or loops in order to pull the garbage bag closed after it has been filled and to keep it in the closed state.

[0005] The individual bin bags on a bin bag roll are typically positioned perpendicular to the roll's length, so that the open side of the bags faces one side and the closed underside faces the other. The material's narrowing, running transversely to the roll, separates the individual bags along their length. However, it is also possible to design bin bag rolls where the individual bags are arranged at a 90° angle, meaning that the side of the bag that will be opened is the one where the material's narrowing is located to separate the individual bags.

[0006] Everything said so far about garbage bag rolls and garbage bags can be implemented within the scope of the invention and especially in embodiments.

[0007] From DE 20 2021 103 927 U1 a roll of garbage bags is known which has film parts in several colors to enable a user to color-code the filled garbage bags and thus facilitate the sorting of the waste by the waste disposal company.

[0008] CN 107792564 A describes a garbage bag with a central partition to form two container areas.

[0009] A garbage bag with two compartments is known from CN 205312322 U.

[0010] US 2011 / 0007986 A1 describes a multi-compartment bag with two or more longitudinal compartments.

[0011] Document KR 200 493 779 Y1 discloses a roll of garbage bags according to the preamble of independent claim 1.

[0012] The object of the present invention is to promote waste separation and to provide improved garbage bags and garbage bag rolls as well as a method for disposing of waste.

[0013] The problem is solved by a waste bag roll with the features according to claim 1 by a method for disposing of waste with the features according to claim 10.

[0014] The garbage bag roll according to the invention thus comprises a plurality of garbage bags rolled one after the other, which can be separated from one another by material weakenings extending in the transverse direction of the garbage bag roll. Each garbage bag has at least one filling opening for waste and at least two garbage bag sections that can be filled via the at least one filling opening. The garbage bag sections can each be separated from the garbage bag without damage, so that after separation from the garbage bag, the garbage bag sections each form separate garbage bags. In addition, each garbage bag has a main bag wall, and at least one connecting wall is provided on the main bag wall, through which garbage bag sections are formed.The connecting walls run at least partially in the longitudinal direction, thus enabling the introduction of waste at a filling depth corresponding to the longitudinal direction, and a material weakening for non-destructive separation is formed on the connecting walls.

[0015] The invention introduces a garbage bag as part of a garbage bag roll, which, with its multiple compartments, allows for the separation of waste / waste while the bag is being filled. The user thus does not need to maintain several individual bins with their respective garbage bags, but can instead take a garbage bag from the roll and place it in a bin, sorting different types of waste within the bag. The ability to separate the compartments to form individual, separate garbage bags allows the sorted waste to be disposed of separately according to its sorting group.The fact that the garbage bag has at least two garbage bag compartments can mean that it has exactly two garbage bag compartments or at least three garbage bag compartments, the latter can comprise exactly three garbage bag compartments or at least four garbage bag compartments, of which the latter can again comprise exactly four garbage bag compartments or at least five garbage bag compartments, of which the latter can again comprise exactly five garbage bag compartments or at least six garbage bag compartments, of which the latter can again comprise exactly six garbage bag compartments or at least seven garbage bag compartments, of which the latter can again comprise exactly seven garbage bag compartments or at least eight garbage bag compartments, of which the latter can again comprise exactly eight garbage bag compartments or at least nine garbage bag compartments, of which the latter can again comprise exactly nine garbage bag compartments or at least ten garbage bag compartments, and so on.

[0016] Advantages can include the fact that a normal film can be provided as the main bag wall during production, especially in the form of a single bag, and the connecting walls can be attached afterwards (welded on, by welding with the application of temperature and / or with pressure).

[0017] According to one aspect of this, it can be provided that the main bag wall is an outer wall and the connecting wall has two layers ("double bag wall"), one of which, after separation, belongs to a first separate garbage bag and the other to a second separate garbage bag.

[0018] The advantages of these designs are that the garbage bag can be easily separated into several smaller garbage bag sections.

[0019] According to an alternative aspect, all connecting walls are provided side by side on one side of the main bag wall. This embodiment can be advantageous in manufacturing, in particular being easy and therefore inexpensive to produce.

[0020] According to embodiments of the invention, the garbage bag areas of the garbage bags are designed differently.

[0021] Firstly, at least two garbage bag compartments can be designed in different sizes; this is particularly to take into account the fact that the different types of waste to be filled in, which are to be separated from each other, do not occur in the same quantities per type.

[0022] Alternatively or additionally, at least two sections of each garbage bag are provided that are different colors. Marking the individual sections of the garbage bag with different colors makes it easier for the user to separate the waste. For example, blue could be for paper waste, brown for organic waste, yellow for plastic waste, etc. Alternatively or additionally, labeling may also be provided.

[0023] According to another preferred embodiment with differently designed bin liner sections, at least two bin liner sections of each bin liner are made of different materials. This can be determined by the type of waste being disposed of. The materials can include at least two types: plastic film, recycled plastic, compostable plastic, aluminum, paper, cellulose, and hemp. Compostable plastic and / or hemp can be advantageous for organic waste, whereas it is not critical if plastic waste is itself encased in plastic film or recycled plastic. For paper waste, the bin liner section can be made of paper. A single bin liner section can also itself be made of different materials. For example, the bin liner section for organic waste can consist of compostable plastic in combination with, or include, a paper reinforcement.The optional drawstring can be made of a different material for garbage bag areas than the rest of the garbage bag area.

[0024] According to preferred embodiments of the invention, the roll of garbage bags provides for several types of garbage bags. Thus, there is at least one garbage bag that differs from the others. This aspect can optionally be considered an invention in itself, independent of the provision of the garbage bag compartments, i.e., the invention described so far. In this aspect, one type of garbage bag can first be detached from the roll, followed by another type. For example, one type of garbage bag can have several compartments, one of which is suitable for paper waste and one for organic waste; this can be accommodated in a compost bin. Another garbage bag can be provided for plastic waste, in which a special compartment (separate garbage bag compartment) is provided for glass.

[0025] The inventive method for waste disposal comprises: Providing a garbage bag with at least two compartments, filling at least one of the compartments, separating the filled compartment from the rest of the garbage bag, and placing the filled compartment in a garbage can / bin.

[0026] Separating the filled compartment can result in a single, separate compartment remaining, which is then filled and placed in a different type of waste bin. Alternatively, separating the filled compartment can also mean leaving the remaining waste bag for further filling. Preferably, compartments are filled with different types of waste for the purpose of waste separation.

[0027] The advantages of the method result from the aforementioned advantages for providing the garbage bag roll according to the invention.

[0028] For the sole purpose of understanding the invention, an exemplary, non-inventive garbage bag roll is described below. In this exemplary, non-inventive garbage bag roll, each garbage bag could comprise a plurality of individual bags that provide the garbage bag compartments, with the individual bags being attached on one side to a common strip (preferably in the manner of a fold). In this case, the individual bags are arranged like a booklet and are particularly preferably open on one side opposite the strip, so that the individual bags can fan out. A suitable, functional garbage can can optionally be provided for this purpose, in which only the strip needs to be attached, and the individual bags can then be fanned out. Furthermore, material weakenings could be formed on the strip.The individual bags can be manufactured separately and welded together on the strip (temperature and / or pressure application), and at the same time the material weakening (e.g. by punching) can be provided.

[0029] For the sole purpose of understanding the invention, an exemplary method, not belonging to the invention, for providing a roll of garbage bags according to the invention is described below. This exemplary method, not belonging to the invention, for providing a roll of garbage bags of the type according to the invention comprises determining a user group and / or a usage period, whereby, based on measurements, it is estimated what types of waste occur and in what quantities for the user group and / or the usage period, and a manufacturing instruction for a roll of garbage bags is provided, consisting of at least two manufacturing instructions for different rolls of garbage bags, each according to the invention, such that the garbage bag sections of the garbage bags have colors and / or dimensions suitable for the estimated quantities. The method concludes with the production of the roll of garbage bags according to the specified manufacturing instruction.For example, a different roll of bin bags can be provided for a "private household with adults" than for a "private household with small children," where the roll needs to have a larger compartment for residual waste (diapers). A distinction can also be made between private households and hotels, where hotels typically don't expect a large amount of organic waste, but rather more paper waste. Therefore, a bin bag for hotels could omit the organic waste compartment entirely, and this waste could be added to the residual waste; compartments for plastic and glass could be combined into one, and so on. The usage period can also dictate which types of waste and in what quantities are generated.For example, more organic waste can be expected in the summer because more and / or better fruit is available, people cook more often with fresh vegetables, and so on.

[0030] The invention is described in more detail below with reference to the drawing, in which Fig. 1 schematically shows a garbage bag roll as a whole; Fig. 2a shows a first variant of a first embodiment of a garbage bag that can be provided by the garbage bag roll; Fig. 2a shows a second variant of the first embodiment of a garbage bag that can be provided by the garbage bag roll; Fig. 3 illustrates a second embodiment of a garbage bag; Fig. 4 illustrates a third embodiment of a garbage bag; and Fig. 5 illustrates a purely exemplary garbage bag not belonging to the invention solely for the purpose of understanding the invention.

[0031] A roll of garbage bags, designated as a whole by 1, consists of a plurality of garbage bags 10-1, 10-2, etc., rolled one after the other, which can be separated from one another by means of material weakenings 12 extending transversely along the roll, for example in the form of perforations. Typically, the first garbage bag 10-1 is separated from the second garbage bag 10-2 and used, while the remaining roll is stored as a supply. The embodiments of garbage bags 10, 10', 10", 10‴ shown below can in principle be provided individually, but are preferably supplied by a roll of garbage bags of the type described in Fig. 1 shown roll of garbage bags provided.

[0032] Fig. 2a shown as garbage bag 10 is a first variant of a first embodiment of the invention, Fig. 2b A second variant of this embodiment is available as a 10' garbage bag.

[0033] In the case of the garbage bag 10, an outer wall 14 is closed and forms a garbage bag in itself, wherein garbage bag sections 16-1, 16-2 are preferably formed on the inside of the outer wall, preferably by welding on a connecting wall, wherein the back of the respective garbage bags is provided by the outer wall 14, and wherein the individual garbage bag sections can be separated from the rest of the garbage bag due to perforations 20. Optionally provided drawstrings 18-1 on the first garbage bag section 16-1 and 18-2 on the second garbage bag section 16-2 are guided through loops, wherein the loops extend on the connecting wall and also on the inside of the outer wall 14.

[0034] At the in Fig. 2b The shown garbage bag 10' according to the second variant of the first embodiment has an open wall 14' as the main bag wall, to which the connecting walls for forming the garbage bag sections 16'-1 and 16'-2 are arranged. Due to the perforation 20', the main bag wall 10' can be divided into two parts, each with a garbage bag section, and each part can then be reused as a separate garbage bag, in particular for disposal after filling. Optional drawstrings 18'-1 and 18'-2 are also provided here.

[0035] At the in Fig. 3 In a second embodiment of the invention, the garbage bag 10" shown has two garbage bag sections 16"-1 and 16"-2 arranged side by side, and each section is provided by a common bag. The connecting walls 22-1 and 22-2 consist of two adjacent (doubled) layers that can be separated from each other by a perforation 20", forming separate garbage bags, each with a drawstring 18"-1 or 18"-2, respectively. The main bag wall in this case is the one shown in Fig, 3 outer wall of the entire garbage bag 10", not marked with a reference symbol.

[0036] At the in Fig. 4 In the shown garbage bag 10‴ according to a third embodiment, a bag is provided as the main bag wall 14‴ which is in Fig. 4 It is open at the top and to which the further garbage bag sections 16"'-1, 16"'-2 and 16"'-3 are attached, being detachable at the perforations 20'-1, 20"'-2 and 20"'-3. This is essentially designed like a glove with detachable fingers. Drawstrings can also be provided here, but these are in Fig. 4 are not shown.

[0037] At the in Fig. 5 The garbage bag 10 IV< shown solely for the purpose of understanding the invention, and which does not belong to the invention, has a plurality of garbage bag sections 16 IV< -1, 16 IV< -2, 16 IV< -3 and 16 IV< -4, which are welded together on a strip 30 in the manner of a fold, wherein a preferably single perforation 20 IV< is formed on the strip. If the strip 30 is torn off, the garbage bag 10 IV< is split into the plurality of garbage bag sections 16 IV< -1, 16 IV< -2, 16 IV< -3 and 16 IV< -4. Each garbage bag section 16 IV< -1, 16 IV< -2, 16 IV< -3 and 16 IV< -4 has a drawstring, here designated by way of example as drawstrings 18 IV< -1 and 18 IV< -4.The individual garbage bag sections 16 IV< -1 to 16 IV< -4 can be manufactured particularly well from different materials, for example paper waste from paper, organic waste from compostable material, especially compostable plastic, plastic from plastic film for plastic and glass from recycled plastic or aluminum with a slightly thicker and more stable wall.

[0038] In all the aforementioned embodiments, it is possible to vary the size and / or intended use of the waste bag compartments, the latter optionally through color and / or labeling. This allows for the determination of which types of waste occur in what proportions within a specific user group, and the size ratios for the waste bag compartments can be adjusted accordingly, with some compartments being omitted entirely.

[0039] The embodiments according to Fig. 2a and 4can be implemented with fewer garbage bag areas than shown, the embodiments according to Fig. 2a , 2b , 3 and 4 also with more garbage bag areas than shown. Bezugszeichenliste
