Description

Technical Field

[0001] The invention relates to a garbage bag roll, a garbage cleaning method and a garbage bag roll providing method. Background Art

[0002] Rolls of garbage bags are a well-known household item. Individual garbage bags can be separated from the roll at the open end by perforations or other material weakenings. Another material weakening can be where the plastic material becomes thinner. Individual garbage bags can usually be separated by hand. In some cases, separation can also be achieved at the material weakening using tools such as a knife or scissors.

[0003] Such garbage bag rolls are usually manufactured in the following way: individual garbage bags are produced separately and then stacked into thin sheets. These thin sheets are fed successively via a feed track into a splicing device, where one thin sheet is spliced ​​to another thin sheet. Splicing techniques are particularly suitable for welding such as by melting (providing high temperature) and / or pressure welding (providing pressure). Then, a weakening of the material is introduced at the connection, such as the perforation mentioned above. In this way, a continuous garbage bag strip is produced. From this, the strip of the number of garbage bags required for the garbage bag roll is separated and rolled up. Then, a paper roll or the like is attached to the rolled garbage bags to prevent them from winding up on their own. Other fixing schemes may also be possible. The individual garbage bags may have a certain complexity, for example, a drawstring is usually provided on the upper side of the garbage bag opening, and the drawstring is guided in a guide and / or loop so that the drawstring is tightened and kept in a closed state after the garbage bag is filled.

[0004] The individual garbage bags in the garbage bag roll are usually arranged transversely to the longitudinal extension of the garbage bag roll, so that the side of the garbage bag that will be opened later points to one side and the closed lower side of the garbage bag points to the other side. The material weakening extending transversely to the garbage bag roll separates the individual garbage bags on their longitudinal sides. In principle, however, the garbage bag roll can also be designed so that the individual garbage bags are offset by 90°, that is, the side on which the garbage bag is to be opened later is the side on which the material weakening for separating the individual garbage bags is provided.

[0005] The above technical contents about garbage bag rolls and garbage bags can all be realized within the scope of the present invention, especially within the embodiments of the present invention.

[0006] Patent document DE 202021103927 U1 discloses a garbage bag roll having film portions in multiple colors so that users can color-code filled garbage bags, thereby making it easier for garbage disposal companies to sort garbage.

[0007] Patent document CN 107792564 A describes a garbage bag with a central partition forming two container areas.

[0008] Patent document CN 205312322 U discloses a garbage bag with two compartments. Summary of the invention

[0009] The present invention aims to promote garbage sorting, provide improved garbage bags and garbage bag rolls and garbage disposal methods.

[0010] In order to achieve the above-mentioned objectives, the present invention proposes a garbage bag roll having the features according to claim 1, a garbage cleaning method having the features according to claim 13, and a garbage bag roll providing method having the features according to claim 14.

[0011] In view of this, the garbage bag roll of the present invention comprises a plurality of garbage bags rolled up one after another, and the garbage bags can be separated from each other by a material weakening portion extending transversely along the garbage bag roll. Each garbage bag has at least one garbage filling opening and at least two garbage bag areas that can be filled through the at least one filling opening. The garbage bag areas can be separated from the garbage bag without damage, so that the garbage bag areas are separated from the garbage bag to form separate garbage bags.

[0012] In this regard, the present invention introduces a garbage bag as part of a garbage bag roll, which has a plurality of garbage bag zones, so that the garbage / waste is separated as early as when the garbage bag is filled. In this way, the user does not have to carry a plurality of separate garbage cans with their respective garbage bags, but can take the garbage bag from the garbage bag roll and put it into the garbage can, and classify the different types of garbage in the garbage bag. Since the garbage bag zones can be separated to form individual garbage bags, the classified collected garbage can be cleaned separately according to the classification groups. The garbage bag has at least two garbage bag zones, which may mean that the garbage bag has exactly two garbage bag zones or at least three garbage bag zones, the latter may include exactly three garbage bag zones or at least four garbage bag zones, the latter may include exactly four garbage bag zones or at least five garbage bag zones, the latter may include exactly five garbage bag zones or at least six garbage bag zones, the latter may include exactly six garbage bag zones or at least seven garbage bag zones, the latter may include exactly seven garbage bag zones or at least eight garbage bag zones, the latter may include exactly eight garbage bag zones or at least nine garbage bag zones, the latter may include exactly nine garbage bag zones or at least ten garbage bag zones, and so on.

[0013] According to an advantageous embodiment of the invention, each garbage bag comprises a main bag wall on which at least one connecting wall is arranged, by means of which a garbage bag region is formed. The connecting wall extends at least partially in the longitudinal direction, so that the garbage can be introduced at a filling depth corresponding to the longitudinal direction, and a material weakening is formed in the connecting region to achieve lossless separation.

[0014] An advantage of this embodiment is that a common film can be provided as the main bag wall during production, especially in the form of a single bag, to which the connecting wall can be attached later (welded by providing high temperature welding and / or pressure welding).

[0015] According to one aspect of the present invention, the main bag wall is an outer wall and the connecting wall comprises two layers ("double bag wall"), one of which belongs to the first separate garbage bag after separation and the other belongs to the second separate garbage bag.

[0016] An advantage of these embodiments is that the waste bag can be easily divided into several smaller waste bag sections.

[0017] According to an alternative aspect, all connecting walls are juxtaposed on one side of the main bag wall. This embodiment is advantageous for production, and is particularly easy to produce, so the cost is low.

[0018] According to other embodiments of the invention, each trash bag may comprise a plurality of individual bags providing a trash bag area, each individual bag being attached on one side to a common strip (preferably in a folded manner).

[0019] In this case, each individual bag is arranged in a folded booklet shape, particularly preferably, opened on the side opposite to the strip, so that the individual bag can be spread out. For this reason, a suitable trash can can be provided if necessary, in which the strip only needs to be fastened, and the individual bags are then spread out.

[0020] According to an embodiment of the invention, the strip is provided with material weakenings. The individual bags can be manufactured separately and welded together on the strip (providing high temperature and / or pressure), while material weakenings can be provided (eg by punching).

[0021] According to embodiments of the present invention, the trash bag area of ​​the trash bag takes different configurations.

[0022] On the one hand, at least two garbage bag areas can be designed to be of different sizes; this is particularly necessary in view of the different quantities of each type of different types of landfill waste to be separated from one another.

[0023] Alternatively or additionally, at least two garbage bag areas of each garbage bag have different colors. By marking the garbage bag areas with different colors, users can more easily sort garbage. For example, blue can represent paper garbage, brown can represent organic garbage, yellow can represent plastic garbage, etc. Optionally, labels can also be provided as an alternative or supplement.

[0024] According to another preferred embodiment in which the garbage bag sections are constructed differently, at least two garbage bag sections of each garbage bag are made of different materials, which may depend on the garbage to be disposed of. These materials may include at least two materials in plastic film, recycled plastic, degradable plastic, aluminum, paper, cellulose and hemp. Degradable plastic and / or hemp are beneficial to organic garbage, and it does not matter whether the plastic garbage itself is in the form of plastic film or recycled plastic. With regard to paper garbage, the garbage bag sections can be made of paper. Each garbage bag section itself can be made of different materials. For example, the garbage bag section for organic garbage can be composed of or contain degradable plastic connected to a paper reinforcement. In the garbage bag section, an optional drawstring can be made of other materials that are different from the relevant garbage bag section.

[0025] According to a preferred embodiment of the present invention, a plurality of types of garbage bags are provided in the garbage bag roll. This means that there is at least one garbage bag that is different from the other garbage bags. This aspect may also be considered as an invention independently of the garbage bag area (i.e., the above-mentioned invention), as appropriate. In this regard, one type of garbage bag may be separated from the garbage bag roll first, and then another type of garbage bag may be separated. For example, a garbage bag may have multiple garbage bag areas, one of which is suitable for paper garbage and one for organic garbage; they may be placed in an organic garbage bin. Another garbage bag may be provided for plastic garbage, wherein a specific compartment (independent garbage bag area) is provided for glass.

[0026] The garbage cleaning method of the present invention comprises:

[0027] - providing a garbage bag having at least two compartments;

[0028] - filling at least one compartment;

[0029] -Separate the filled compartment from the rest of the trash bag;

[0030] - Throw filled compartments into the trash / rubbish container.

[0031] Separating the filled compartments may be accompanied by a single additional compartment remaining, which is in turn filled and thrown into a different type of waste bin. However, separating the filled compartments may also mean that the rest of the waste bag remains to be filled further. For waste separation purposes, different filled compartments are preferably filled with different types of waste.

[0032] The advantages of the above method derive from the aforementioned advantages of providing the trash bag roll of the present invention.

[0033] According to the invention, the method for providing a garbage bag roll of the type of the invention comprises: determining a user group and / or a period of use, estimating the type and amount of garbage that occurs in the user group and / or period of use based on the measured values, and specifying the garbage bag roll production specifications from at least two production specifications of different garbage bag rolls of the type according to the invention, so that the garbage bag area of ​​the garbage bag has a color and / or size that matches the estimated amount. The above method ends with the production of garbage bag rolls according to the specified production specifications. For example, different garbage bag rolls can be provided for the user groups "adult private homes" and "private homes with infants and young children", the latter garbage bag rolls must have a larger garbage bag area for residual garbage (diapers). The user groups can also distinguish between private homes and hotels, which are generally not expected to generate a lot of organic garbage, but more paper garbage. For example, the garbage bag area for organic garbage can be completely omitted in the garbage bags for hotels, and such garbage can be allocated to residual garbage if necessary; the garbage bag areas for plastics and glass can be combined into one garbage bag area, and so on. The period of use itself may also determine the type and amount of garbage generated. For example, more and / or better quality fruit may be available in the summer, cooking with fresh vegetables is more frequent, etc., so more organic waste is expected.
