Description

[Technical field]

[0001] The present invention relates to a roll of garbage bags, a method of disposing of garbage, and a method of providing a roll of garbage bags.

[0002] A roll of garbage bags is commonly known as a household item. A single garbage bag can be separated from the roll of garbage bags at its open end at a perforation or other weakened portion of material, such as a thinned portion of plastic material. Usually, the single garbage bag is separated manually. However, the weakened portion of material can also be separated using a tool such as a knife or scissors.

[0003] Such garbage bag rolls are typically produced in such a way that the individual garbage bags are produced separately and then folded into sheets. These sheets are guided via a feed track to a connecting device, where one sheet is connected to another. Particularly suitable connecting techniques are welding, for example by melting (by applying heat) and / or crimping (by applying pressure). At the connecting location, a material weakening, such as the aforementioned perforation, is then provided. In this way, a continuous strip of garbage bags is produced. A strip with the desired number of garbage bags for the garbage bag roll is separated therefrom and wound up. A roll of paper or the like is applied over the wound garbage bags to prevent the garbage bags from unraveling spontaneously. Other fastening methods are also possible. The individual garbage bags may be of some complexity and are regularly provided with a drawstring guided by a guide and / or a loop above the opening of the garbage bag in order to tie the garbage bag closed after it has been filled.

[0004] The individual bags in the bag roll are usually arranged transversely to the longitudinal extent of the bag roll, so that the rear open side of the bag faces one side and the closed underside of the bag faces the other side. The material weakening extending transversely to the bag roll therefore separates the individual bags on their long side. However, in principle it is also possible to design a bag roll in which the individual bags are allocated with a 90° shift, in which case the rear open side of the bag is provided with a material weakening for separating the individual bags.

[0005] All of the trash bag rolls and trash bags described thus far may be realized within the scope of the present invention, particularly in the embodiments.

[0006] From DE 20 2021 103 927 U1, a garbage bag roll is known which has film sections of several different colours, which allows the user to characterise the filled garbage bags by colour, thus facilitating the sorting of the garbage on the part of the garbage disposal operator.

[0007] CN 107792564 A describes a garbage bag with a central partition wall that forms two container areas.

[0008] From CN 205312322 U a garbage bag having two compartments is known.

[0009] SUMMARY OF THE PRESENT EMBODIMENT It is an object of the present invention to provide an improved trash bag and bag roll, and method for trash disposal, which facilitates waste separation.

[0010] This problem is solved by a garbage bag roll having the features according to claim 1, a garbage removal method having the features according to claim 13 and a method for providing a garbage bag roll according to claim 14.

[0011] The garbage bag roll according to the invention comprises a plurality of garbage bags wound one behind the other, the garbage bags being separable from one another by a material weakening extending laterally of the garbage bag roll, each garbage bag having at least one filling opening for garbage and at least two garbage bag areas which can be filled via said at least one filling opening, the garbage bag areas being non-destructively separable from the garbage bag, such that the garbage bag areas each form a separate garbage bag after separation from the garbage bag.

[0012] Thus, the present invention introduces a garbage bag as part of a garbage bag roll, with multiple garbage bag areas, allowing for garbage / waste separation already when filling the garbage bag. Thus, instead of having to prepare multiple separate garbage bins, each with a garbage bag, the user can transfer one garbage bag from the garbage bag roll into a garbage bin and separate different types of waste within that garbage bag. Due to the possibility of separating the garbage bag areas to form individual separate garbage bags, the separated and collected waste can be processed separately for each separation group. A trash bag having at least two trash bag regions can include having exactly two trash bag regions or at least three trash bag regions, which may include exactly three trash bag regions or at least four trash bag regions, of which the latter may include exactly four trash bag regions or at least five trash bag regions, of which the latter may include exactly five trash bag regions or at least six trash bag regions, of which the latter may include exactly six trash bag regions or at least seven trash bag regions, of which the latter may include exactly seven trash bag regions or at least eight trash bag regions, of which the latter may include exactly eight trash bag regions or at least nine trash bag regions, of which the latter may include exactly nine trash bag regions or at least ten trash bag regions.

[0013] According to an advantageous embodiment of the invention, each waste bag has a main bag wall which is provided with at least one connecting wall, via which a waste bag region is formed, the connecting wall extends in the longitudinal direction at least for each section, so that waste can be introduced to a corresponding filling depth in the longitudinal direction, and the connecting region is formed with a material weakening for non-destructive separation.

[0014] The advantage of this embodiment is that during production a normal film can be provided as the main bag wall, especially also in the form of a single bag; It may then be possible to attach the connecting wall (welded by means of thermal and / or pressure application).

[0015] According to one embodiment, it may be provided that the main bag wall is an outer wall and the connecting wall comprises two layers (a "double bag wall"), one of which after separation belongs to a first separate trash bag and the other of which belongs to a second separate trash bag.

[0016] An advantage of these embodiments is that the trash bag can be easily separated into multiple smaller trash bag portions.

[0017] According to an alternative embodiment, it is provided that all the connecting walls are arranged next to one another on one side of the main bag wall, this embodiment being advantageous in terms of production and in particular being easy and therefore cheap to manufacture.

[0018] According to another embodiment of the invention, each garbage bag can comprise a number of individual bags providing a garbage bag area, the individual bags being attached (preferably in the form of folds) to a common strip on one side,

[0019] In this case, the individual bags are arranged like a booklet and are particularly preferably open on the opposite side of the strip so that the individual bags can be fanned out or unfolded. If necessary, a suitably adapted waste bin can be provided in which the individual bags can be fanned out simply by attaching the strip.

[0020] According to an embodiment, it is provided that the material weakening is formed in the strip: the individual bags can be manufactured separately and welded to one another in the strip (temperature and / or pressure application) while the material weakening is provided (for example by punching).

[0021] According to an embodiment of the present invention, the trash bag regions of the trash bag are configured differently.

[0022] On the one hand, the at least two garbage bag areas can be formed with different sizes; this is in particular to take into account the fact that different types of garbage to be filled should be separated from one another, but that not the same amounts occur per type.

[0023] Alternatively or additionally, it is provided that at least two of the trash bag regions of each trash bag have different colors. By marking the individual trash bag regions with different colors, it is possible to facilitate the user in separating the trash. For example, blue for paper trash, brown for food waste, yellow for plastic trash, etc. In some cases, labels can also be attached additionally or alternatively.

[0024] According to another preferred embodiment with differently formed trash bag areas, at least two trash bag areas of each trash bag are made of different materials. This depends on the trash to be disposed of. The materials can comprise at least two of the following: plastic film, recycled plastic, compostable plastic, aluminum, paper, cellulose, hemp. While compostable plastic and / or hemp are advantageous for food waste, it is immaterial whether the plastic waste itself is provided with plastic film or recycled plastic. In the case of paper waste, the trash bag area can be made of paper. The individual trash bag areas can also be made of different materials. For example, the trash bag area for food waste can be made of or include compostable plastic combined with a paper reinforcement. An optional drawstring for a trash bag area can be made of a different material than the rest of the trash bag area in question.

[0025] According to a preferred embodiment of the invention, more types of garbage bags are provided on the garbage bag roll. Thus, there is at least one garbage bag that is different from the other garbage bags. Where appropriate, this aspect can also be considered as an invention in itself, independently of the provision of the garbage bag area, i.e. the invention described so far. In this aspect, first one type of garbage bag can be separated from the garbage bag roll, and then another type of garbage bag can be separated. For example, a type of garbage bag can have several garbage bag areas, one of which is suitable for paper waste and one for food waste; this can be accommodated in a food waste bin. Another garbage bag can be for plastic waste, and a special compartment (another garbage bag area) for glass can be provided.

[0026] The waste disposal method according to the present invention comprises: - providing a trash bag having at least two compartments; - filling at least one of the compartments; - separating the filled compartment from the rest of the garbage bag; - removing the filled compartment into a trash can / garbage container; Includes.

[0027] Separating the filled compartments leaves only one further compartment which is filled and transferred to another type of trash bin. However, separating the filled compartments also includes leaving the remaining trash bags for further filling. Preferably, the different filled compartments are filled with different types of trash for trash sorting.

[0028] The advantages of this method arise from the advantages previously described for providing a roll of garbage bags according to the invention.

[0029] The method according to the invention for providing a trash bag roll of the type according to the invention comprises determining a (one or more) user group and / or period of use, for which it is estimated based on measurements which type of waste is generated in what amount, and assigning a production instruction for a trash bag roll from at least two production instructions for different trash bag rolls, each according to the type of the invention, such that the trash bag area of ​​the trash bag has a color and / or size that matches the estimated amount. The method ends with manufacturing the trash bag roll according to the assigned production instruction. For example, a user group "private households with adults" can be provided with a different trash bag roll than a "private households with small children", in which case the trash bag roll needs a larger trash bag area for restmuell (diapers). A distinction can also be made between user groups, namely, households and hotels, where a large amount of food waste is not usually expected, but a large amount of paper waste is expected. For example, a trash bag for a hotel can omit a trash bag area for food waste, which can be assigned to restmuell if necessary. The plastic and glass waste bag areas can be combined to form a garbage bag area, etc. The period of use can also determine what type and how much waste is generated: for example, in summer, more food waste is expected because more and / or better fruits are available, fresh vegetables are cooked more frequently, etc. [Brief description of the drawings]

[0030] The present invention will now be described in more detail with reference to the drawings in which: [Figure 1] FIG. 1 is a schematic diagram showing an entire garbage bag roll. [Figure 2a] FIG. 2a shows a first variation of a first embodiment of a garbage bag that can be provided by a garbage bag roll. [Figure 2b] FIG. 2b shows a second variation of the first embodiment of a garbage bag that can be provided by a garbage bag roll.

[0031] A roll of garbage bags, generally designated by reference numeral 1, is made up of a number of garbage bags 10-1, 10-2, etc., wound one behind the other, and the garbage bags can be separated from one another by material weakening portions 12, e.g. in the form of perforations, that extend in the lateral direction of the roll of garbage bags. Typically, a first garbage bag 10-1 is used by being separated from a second garbage bag 10-2, while the remaining garbage bag roll is kept as stock. Garbage bags 10, 10', 10'', 10''', 10 shown below are IV The embodiment of can in principle be provided individually, but preferably can also be provided by a garbage bag roll, such as the garbage bag roll 1 shown in FIG.

[0032] FIG. 2a shows a first variant of a first embodiment of the invention as trash bag 10, and FIG. 2b shows a second variant of this embodiment as trash bag 10'.

[0033] In the garbage bag 10, the outer wall 14 is closed and forms a garbage bag by itself, and on the inside of the outer wall, the garbage bag sections 16-1, 16-2 are formed, preferably by welding to the connecting wall, the back side of each garbage bag being provided by the outer wall 14, and the individual garbage bag sections can be separated from the remainder of the garbage bag by means of perforations 20. The drawstrings 18-1 and 18-2, which are optionally provided on the first garbage bag section 16-1 and on the second garbage bag section 16-2, are guided by loops which extend to the connecting wall and also to the inside of the outer wall 14.

[0034] In the garbage bag 10' shown in Fig. 2b according to the second variant of the first embodiment, an open wall is provided as the main bag wall 14', on which connecting walls are arranged to form the garbage bag areas 16'-1 and 16'-2. By means of the perforations 20', the main bag wall 10' can be divided into two parts, each with a garbage bag area, each part can therefore be further used as a separate garbage bag (separater Muellbeutel) and can be discarded, in particular after filling. Optional drawstrings 18'-1 and 18'-2 are also provided here.

[0035] In the trash bag 10'' shown in Figure 3 according to the second embodiment of the invention, two trash bag regions 16''-1 and 16''-2 are formed adjacent to each other, each region being provided by a common bag with two adjacent (double) layers as connecting walls 22-1 and 22-2, which can be separated from each other by perforations 20'' to form separate trash bags with drawstrings 18''-1 and 18''-2, respectively. The main bag wall is in this case the outer wall of the entire trash bag 10'', which is not numbered in Figure 3.

[0036] In the third embodiment of the garbage bag 10''', shown in FIG. 4, a bag is provided as main bag wall 14''', which is open at the top in FIG. 4, to which further garbage bag areas 16'''-1, 16'''-2, 16'''-3 are attached, whereby they are separable at perforations 20'''-1, 20'''-2, 20'''-3. In principle, the design is like a glove with separable fingers. Drawstrings can also be provided here, but are not shown in FIG. 4.

[0037] A garbage bag 10 according to a fourth embodiment of the present invention, as shown in FIG. IV In the multiple garbage bag area 16 IV -1, 16 IV -2, 16 IV -3 and 16 IV -4, which are welded in the manner of folds in the strip 30 and preferably have a single perforation 20 IVWhen the strip 30 is torn off, the garbage bag 10 IV Includes multiple trash bag areas (16) IV -1, 16 IV -2, 16 IV -3, 16 IV -4. Each garbage bag area is 16 IV -1, 16 IV -2, 16 IV -3, 16 IV -4 has a drawstring, and the example shown here is drawstring 18 IV -1 and 18 IV In this embodiment, the individual garbage bag sections 16 IV -1~16 IV -4 can in particular be made of different materials, for example paper for paper waste, compostable material for food waste, in particular compostable plastic, plastic film for plastic, recycled plastic for glass, or even aluminium with a rather thick and stable wall.

[0038] In all the above embodiments, the size and / or purpose of the trash bag areas can be varied, the latter possibly by colouring and / or labelling. In this way it can be determined what type of trash is generated by a particular user group and size ratios of the trash bag areas can be provided accordingly, with some trash bag areas being omitted entirely.

[0039] The embodiments according to Figures 2a, 4 and 5 may be implemented with less trash bag area than shown, and the embodiments according to Figures 2a, 2b, 3, 4 and 5 may be implemented with more trash bag area than shown. [Explanation of symbols]
