[0004] Bag strand, in particular a rollable or rolled-up bag strand

[0005] Description

[0006] The present invention relates to a strand of bags, and in particular to a rollable and a rolled-up strand of bags.

[0007] Plastic bag strands have long been known and are ubiquitous. They are used, for example, as rolled-up garbage bags or as rolled-up pouches, such as those found at fruit and vegetable counters. These rolled-up bag strands are space-saving and can be separated via suitable perforation lines located near the bottom of the bag. However, this sometimes requires considerable force or the use of tools such as scissors or knives. Tearing a bag can therefore result in damage. Alternatively, as described in DE 26 27 927 Ai, rolled-up plastic bags are also used that are not connected to each other but are wound using the so-called interleaving method. In this method, adjacent bags overlap in sections.Especially when such rolls of bags are nearing their end, it is often no longer possible to remove individual bags without also unwinding the following bag(s) at the same time.

[0008] The present invention was based on the objective of making available bag strands that are no longer afflicted with the disadvantages of the prior art and that, in particular, ensure a safe and reliable provision of individual bags up to the last bag of a bag strand, regardless of the bag size.

[0009] Accordingly, according to a first embodiment of the invention, a bag strand with a strand start and a strand end was found, containing a plurality of bags connected in pairs, each formed from or comprising a front wall paper web, comprising an inner and an outer surface, and a back wall paper web, comprising an inner and an outer surface, each with two opposing first and second side edges, wherein the inner surfaces of the front and back wall paper webs are connected to each other at intervals, in particular planarly, from or spaced apart from the corresponding first side edges in the direction of or up to the corresponding second side edges, forming bag bottom areas, wherein, with respect to the strand start, at least one weakening area or at least one weakening line is present beyond the respective bag bottom areas.extending from or spaced apart from the corresponding first side edges towards or up to the corresponding second side edges of the front and back paper webs, wherein the joining of the bag bottom areas is based on cold glue, cold seal glue, heat seal glue or hot melt adhesives, in particular cold glue.

[0010] In the case of the numerous bags connected in pairs according to the first embodiment, separation along the weakening area or weakening line creates the bag opening. The weakening area or weakening line located at the end of the strand is regularly used for bag separation, particularly when the bag strand according to the invention is coiled and coiling begins at the beginning of the strand.

[0011] The bag bottom areas, formed by joining the inner surfaces of the front and back paper webs, can be linear or, in particular, planar, and preferably extend from the corresponding first side edges to the corresponding second side edges of the front and back paper webs. The interval-like arrangement of the bag bottom areas, as defined in the invention, means that the bag bottom areas extending from or at a distance from the corresponding first side edges towards or up to the corresponding second side edges do not directly adjoin one another or exist side by side without a transition, but are each arranged at a distance from one another, so that at least one weakening area or weakening line can exist between adjacent bag bottom areas, and bag walls remain that provide a fillable bag volume.The weakening areas or lines are preferably located directly adjacent to or near the bag bottom areas. Within a bag strand, the weakening areas or lines are preferably located on the side, relative to the adjacent bag bottom area, that is further away from the start of the strand than this adjacent bag bottom area.

[0012] Such embodiments according to the first embodiment of the bag strands according to the invention, with a strand start and a strand end, are preferred, comprising a plurality of bags connected in pairs, formed from or comprising a front wall paper web, comprising an inner and an outer surface, and a back wall paper web, comprising an inner and an outer surface, each with two opposing first and second side edges, wherein the inner surfaces of the front and back wall paper webs are interconnected at intervals from the corresponding first side edges to the corresponding second side edges, forming bag bottom areas, wherein, with respect to the strand start, at least one weakening area or at least one weakening line is present beyond the respective bag bottom areas.extending from the corresponding first side edges to the corresponding second side edges of the front and back paper webs, wherein the joining of the bag bottom areas is based on cold glue, cold seal glue, heat seal glue or hot melt adhesives, preferably on cold seal glue, heat seal glue or hot melt adhesives and particularly preferably on cold seal glue.

[0013] Furthermore, embodiments according to the first embodiment of the bag strands according to the invention are particularly suitable in which the front and back paper webs are at least partially connected along or in the area of ​​corresponding side edges, or merge directly or via side folds. A cold adhesive, cold sealant, heat sealant, or hot melt adhesive is preferably used for the connection; a cold adhesive or hot melt adhesive, and in particular a hot melt adhesive, is preferred.

[0014] In the embodiments according to the first embodiment of the bag strands according to the invention, if the front and back paper webs transition directly into one another along corresponding side edges, a fold is regularly present at this transition. This fold is preferably formed as a crease. Such folded side edges generally form sharp creases. These creases are obtained using a tool or by machine.

[0015] The cold sealant may preferably comprise or be based on natural rubber and / or synthetic elastomers, in particular comprising or based on vinyl acetate polymers, vinyl acetate copolymers, acrylic polymers, styrene-butadiene rubber, butyl rubber, or polychloroprene. The cold sealant is typically applied cold, preferably at room temperature (20 °C), and the adhesive bond is created by mechanical compression without the application of heat. In other words, cold compression (at room temperature) takes place. Preferably, the cold sealant is applied to both surfaces that are to be joined.

[0016] The heat-sealable adhesive preferably comprises or is based on heat-sealable acrylic lacquer. The heat-sealable adhesive is typically applied cold, preferably at room temperature (20 °C), and the adhesive bond is created by mechanical pressing in a heated state, i.e., under heat. The heat-sealable adhesive can also be applied to only one surface to create a bond with another surface. Preferably, the heat-sealable adhesive is applied to both surfaces that are to be joined.

[0017] The hot melt adhesive preferably comprises or is based on ethylene vinyl acetate copolymers, ethylene ethyl acrylate copolymers, in particular ethylene / n-butyl acrylate copolymers, polyesters, polyacrylates, polyamides, polyurethanes, polyolefins, polyvinyl acetates, polyvinyl alcohols, polyvinyl butyral, polyisobutylene, ethylene / methacrylate copolymers, and / or styrene block copolymers, in particular ethylene vinyl acetate copolymers. Hot melt adhesives are typically applied hot, i.e., in the molten state, and the adhesive bond is formed by mechanical compression while hot, i.e., in the heated state. The hot melt adhesive can also be applied to only one surface to create a bond with another surface. Preferably, the hot melt adhesive is applied to both surfaces to be joined.

[0018] Cold glue preferably comprises or is based on polyvinyl acetate. Cold glue is typically applied cold, preferably at room temperature (20 °C), and the adhesive bond generally forms simply by contacting the surface to be joined, without the need for heating. Unlike cold-sealable and hot-sealable adhesives, no comparable pressure is required to create a bond. Applying the cold glue to a surface is usually sufficient to achieve an adhesive bond.

[0019] Cold sealant, hot sealant, and cold glue according to the invention are preferably aqueous preparations. In a particularly advantageous embodiment according to the first embodiment of the bag strands according to the invention, exactly one weakening area or exactly one weakening line is present beyond the respective bag bottom areas at the beginning of the strand, which extends from or spaced apart from the corresponding first side edges in the direction of or up to the corresponding second side edges of the front and back paper webs, or preferably extends from the corresponding first side edges up to the corresponding second side edges of the front and back paper webs.

[0021] The front wall paper web and the back wall paper web according to the first embodiment of the bag strands according to the invention are preferably formed in one piece. In this embodiment, the front and back wall paper webs form a continuous paper web. This paper web, when spread out on a flat surface, preferably has two opposing longitudinal edges. By folding this paper web twice parallel to the longitudinal edges, the front wall paper web is formed between the parallel fold lines. On the reverse side of the front wall paper web, the two longitudinal edges overlap and are joined together in the overlap area, preferably with a cold glue, cold sealant, heat sealant, or hot melt adhesive, and particularly preferably with a cold glue or hot melt adhesive.In this embodiment, the two paper web sections, each extending from the fold lines to the longitudinal side edges and joined in the overlap area, form the backing paper web. The two folds in the paper web preferably represent creases. Accordingly, in the embodiment described above, the fronting paper web is preferably enclosed by opposite side edges in the form of creases. Alternatively, the paper web can also be folded along its longitudinal axis in the middle or approximately in the middle, so that the fronting paper web and the backing paper web are formed by folding the two paper web halves over each other. This longitudinal fold is preferably designed as a crease.The bonding at the opposite side edges of the front wall paper web and back wall paper web is preferably carried out with a cold glue, cold sealing glue, heat sealing glue or hot melt adhesive, particularly preferably with a cold glue or hot melt adhesive and especially with a cold glue.

[0058] In particularly advantageous embodiments, the front wall paper web, the back wall paper web, the front wall paper web sections, the paper bags, the paper web sections and / or the paper strips of the bag strands according to the invention have a basis weight in the range of 25 to 150 g / m². 2, preferably in the range of 40 to 120 g / m² 2 and especially preferably in the range of 35 to 60 g / m² 2 , on.

[0059] In particularly advantageous embodiments, it may also be provided that the front wall paper web, the back wall paper web, the front wall paper web sections, the paper bags or the paper web sections have a width in the range of 8 to 40 cm, preferably in the range of 20 to 30 cm.

[0060] Furthermore, in particularly advantageous embodiments, it can be provided that the distance between adjacent weakening areas or lines is in the range of 8 to 70 cm, preferably 20 to 45 cm.

[0061] The weakening areas or lines of the pouch strands according to the invention can, for example, have a wavy or jagged shape.

[0062] The weakening areas or lines are particularly likely to be present as perforation areas or lines.

[0063] Alternatively, the weakening areas or lines can be provided to include or represent cutouts or cuts. These cutouts or cuts preferably constitute 10 to 90% and particularly preferably 30 to 70% of the distance between the opposing side edges of the front wall paper web and the back wall paper web.

[0064] In a further embodiment, the bags of the bag strands according to the invention can have an inwardly folded side gusset on each side edge.

[0065] The bag strands according to the invention are preferably in the form of a wound or coiled bag roll strand. The bag strands according to the invention can also be wound, for example, onto a rod or shaft. Alternatively, the bag strands according to the invention can be in the form of a folded bag strand in which the back wall of the first bag abuts the back wall of the second bag and the front wall of the second bag abuts the front wall of the third bag, with the folding direction changing at the bag transition.

[0066] In the wound-up, roll-forming bag strands according to the invention, the weakening areas or lines are, in a advantageous embodiment, essentially parallel or, in particular, aligned parallel to the winding axis. The wound-up bag strands according to the invention may retain a hole in their core for the passage of a pin or shaft.

[0067] The bag strands according to the invention, in particular the rolled-up bag strands, are especially suitable for storing bags that can be separated as needed to hold or transport, for example, food, in particular fruit, vegetables or bakery products such as bread.

[0068] The present invention is based on the surprising finding that the existing rolled or rollable bag strands can be manufactured almost entirely, and in particular essentially entirely, from paper material. The invention thus provides access to rollable or rolled bag strands made from renewable resources. Furthermore, it is surprising that bags can be easily and readily separated from the rolled or rollable bag strands according to the invention. Regardless of the type of force applied, the bag always tears at the designated tear points. Improper tearing is not regularly observed, nor do the bag walls tear or the seams connecting the front and back sides open.Very thin-walled bag materials can also be used, which significantly reduces the weight of continuous bag rolls compared to conventional continuous bag rolls. Furthermore, it has been found that the wound bags according to the invention can always be handled perfectly, regardless of how many bags have already been unwound from a single bag strand. Due to the weight of the wound bag strand itself, there is no longer any unwinding of bag rolls when the bag supply is running low. The bag strands according to the invention offer the advantages described above in a structurally simple manner. Further details and advantages of the present invention are described in more detail with reference to the following figures.

[0075] Figure 4 shows a view of the front of a section of a bag strand according to a third embodiment of the invention in the unrolled state.

[0076] Figure ia shows a view of the front of a section of a bag strand (1) according to a first embodiment of the invention in its unwound state. In Figure ia, the beginning and end of the strand are indicated by reference numerals (2) and (4), respectively, but are not explicitly shown. The bag strand (1) according to the invention comprises a plurality of bags (10) connected in pairs. In Figure ia, two connected bags (10) of the bag strand (1) are shown in full, and two bags are indicated in sections. The bag strand shown or indicated in Figure ia is formed from a front wall paper web (12) with an inner and an outer surface (14, 16) and a back wall paper web (20) with an inner and an outer surface (22, 24). The front wall paper web (12) and the back wall paper web (20) each have two opposing first and second side edges (18, 26; 32, 34).The first side edges of the front (12) and back paper webs (20) can be part of a common side fold. Alternatively, they can be bonded together. Similarly, the second side edges of the front (12) and back paper webs (20) can be part of a common side fold or separate and bonded together. In the embodiment shown in Figure 1a, the corresponding first side edges (18 and 32) and the corresponding second side edges (26 and 34) of the front and back paper webs (12; 20) merge directly into one another. The front paper web (12) and the back paper web (20) are thus formed as a single piece. This single paper web (40) forming the front and back paper webs (12; 20) has two longitudinal side edges (42, 44) that overlap in the joining area (46).In the joining area (46), which in the illustrated embodiment is arranged centrally on the back side as shown in Figure ib, the bond can be made using a cold glue, cold sealant, heat sealant, or hot melt adhesive, preferably a cold glue or hot melt adhesive, and particularly a hot melt adhesive. Alternatively, the joining area (46) can also be arranged in the region of the first or second side edges of the front and back walls. In the illustrated embodiment, the inner surfaces (12; 22) of the front and back wall paper webs (12; 20) are joined together over a surface area at intervals from the corresponding first side edges (18; 32) to the corresponding second side edges (26; 34), forming bag bottom areas (28).The joining of the bag bottom areas (28) in the first embodiment of a bag strand according to the invention, shown in Figure ib, is preferably based on cold-seal adhesive, heat-seal adhesive, or hot-melt adhesives, and particularly on cold-seal adhesive. A weakening line (36) is present beyond the bag bottom area (28) with respect to the strand start (2). This line extends from the corresponding first side edges (18; 32) to the corresponding second side edges (26; 34) of the front and back paper webs (12; 20). It is also possible to have the perforation lines not start directly at the corresponding first and second side edges. Separation along a perforation line automatically forms a bag opening.If a sufficiently large distance is chosen between the bag bottom area (28) and the adjacent perforation line, the section remaining below the bag bottom area (28) can be folded over onto the front or back wall and glued to it to reinforce the bottom area, for example with a cold sealant, hot sealant or cold glue, preferably with a cold glue, applied beforehand to this remaining section.

[0077] Figure 2 shows a view of the front of a section of a bag strand (1') according to a second embodiment of the invention in its unwound state. In Figure 2, the beginning and end of the strand are indicated by reference numerals (2) and (4), but are not explicitly shown. The bag strand (1') according to the invention comprises a plurality of bags (10) connected in pairs. In Figure 2, two interconnected bags (10) of the bag strand (1') are shown in their entirety, while two bags are indicated in sections. These extend on either side of the interconnected bags. The bag strand shown in Figure 2 is shown in its entirety.The indicated bag strand (1') is formed from a back wall paper web (20) with an inner and an outer surface (22, 24) with opposing first and second side edges (32, 34) and a plurality of front wall paper web sections (50), each of which has an inner and an outer surface (52, 54) with opposing first and second side edges (53, 55) as well as a bottom edge (58) and an opening edge (56). In the illustrated embodiment, the front wall paper web sections (50) are connected to each other along the first and second side edges (53, 55) with the corresponding first and second side edges (32, 34) of the back wall paper web (20).The inner surfaces (52) of the front wall paper web sections (50) are also bonded to the back wall paper web (20) at their respective bottom edges (58) from the first side edge (53) to the second side edge (55), forming bag bottom areas (28), preferably using a cold-seal adhesive, heat-seal adhesive, or hot-melt adhesive, and in particular a cold-seal adhesive or one based thereon. The bottom edge (58) of the front wall paper web sections (50) is located further away from the strand start (2) than the opening edge (56) of a bag (10). Furthermore, the bottom edge (58) of a front wall paper web section (50) of a bag (10) and the opening edge (56) of a front wall paper web section (50) of an adjacent bag (10) are spaced apart from each other.In this way, an exposed back wall paper web area (60) remains between these adjacent bags, in which a weakening line (36) is arranged, extending from the first side edge (32) to the opposite second side edge (34) of the back wall paper web (20). In a further development of the embodiment according to Figure 2, the inner surfaces (52) of the front wall paper web sections (50) can have an area in the region of the opening-side edge (56) coated with cold-seal adhesive, heat-seal adhesive, or a hot-melt adhesive, preferably a cold-seal adhesive, which extends from the first side edge (53) to the opposite second side edge (55) of the front wall paper web sections (50). In this way, a bag can be filled and immediately sealed before and after separation from the bag strand (1').Furthermore, sealing after bag separation is achieved by applying a cold-seal adhesive, particularly to the inner surface (22) of the back wall paper web (20) in the area between the weakening line (36) and the adjacent opening-side edge (56). After the bag (10) is separated along the perforation line, the section of the back wall paper web (20) extending beyond the opening-side end is folded over the opening-side edge (56) onto the outer surface of the front wall paper web section (50) and glued to it. Alternatively, or particularly additionally, it can be provided that the inner or outer surface (22, 24) of the back wall paper web (20) in the area between the weakening line (36) and the adjacent bag bottom area (28) is also coated with a cold-seal adhesive.The bottom area of ​​the bag can be reinforced by folding this section remaining below the bag bottom area (28) over onto the front or back wall and then gluing it in place.

[0078] Figure 3a shows a view of the front of a first embodiment of a section of a bag strand (1"') according to a fourth embodiment of the invention in its unwound state. In Figure 3a, the strand beginning and end are indicated by reference numerals (2) and (4), but are not explicitly shown. The bag strand (1"') according to the invention comprises a plurality of bags (10) connected in pairs. In Figure 3a, two interconnected bags (10) of the bag strand (1) are shown in full, and two bags are indicated section by section. The bag strand shown in Figure 3a is a section of the bag strand (1).The indicated bag strand (i“') is formed from a plurality of sequentially successive paper bags (70) arranged along a longitudinal axis, each with a front wall (72) having an inner and an outer surface (73, 74) and a back wall (75) with an inner and an outer surface (76, 77) and a closed bottom end (79) and an open opening end (78). The bottom end (79) of each bag (70) faces the opening end (78) of the adjacent bag (70). Furthermore, in the illustrated embodiment, the bottom end (79) of each bag (70) is spaced apart from the opening end (78) of the adjacent bag (70). In the illustrated embodiment, the bag strand (i“') according to the invention also comprises a paper strip (90) with a first side edge and an opposing second side edge.In the embodiment shown in Figure 3a, the paper strip has a width that is less than one-quarter of the width of the paper bags (70). This allows for the production of fully functional, rollable, or rolled-up bag strands according to the invention while using very little material. The paper strip is connected to each bag (70) of the bag strand (1) and generally extends from the beginning (2) of the strand to the end (4). As shown in Figure 3a, the multiple paper bags (70) can each be connected to the paper strip (90) via the outside of the back wall. This connection of the paper strip (90) to the outside of the back wall of the bags can be achieved using, in particular, cold glue or hot melt adhesives.This connection can extend along the entire length of the outer surface of the back wall or be present only in sections, for example, not in the areas adjacent to the bottom end (79) and adjacent to the opening end (78). In the illustrated embodiment, since the bottom end (79) of one bag (70) is spaced apart from the opening end (78) of the adjacent bag (70), the paper strip extends in a section (96) between these adjacent bags. In this exposed section (96), which is located in the area of ​​the bottom end (79) of one bag (70) and the opening end (78) of the adjacent bag (70), there is a weakening line (36) extending from the first side edge (92) to the opposite second side edge (94) of the paper strip.Depending on where the weakening line (36) is located in the exposed section, a section remains that can be folded over the opening-side end to the outside of the front wall, and / or a section remains that can be folded over the bottom-side end to the outside of the front wall of the adjacent bag. By applying a cold-seal adhesive, in particular, to the inside of the paper strip in the spaced area between the bottom-side end (79) of one bag (70) and the opening-side end (78) of the adjacent bag (70), in other words, the exposed section (96), the bottom area of ​​one bag can be reinforced, and the opening-side area of ​​the adjacent bag can be sealed.

[0079] Figure 3b shows a view of the front of a second embodiment of a section of a bag strand (1"') according to the fourth embodiment of the invention in its unrolled state. This second embodiment differs from the first embodiment in that the bottom end (79) of one bag (70) is located directly adjacent to the opening end (78) of the neighboring bag (70). In this embodiment, the weakening line (36) is advantageously located in the paper strip in the area of ​​the transition between the bottom end (79) of the bag (70) and the opening end (78) of the neighboring bag (70).If the connection of the paper strip (90) with the outside of the back wall of the bags is not located in the areas adjacent to the bottom end (79) and the opening end (78) of the respective adjacent bag, the weakening line (36) may also be located in these unconnected sections of the paper strip.

[0080] Figure 3c shows a view of the front of a third embodiment of a section of a bag strand (1"') according to the fourth embodiment of the invention in its unrolled state. This third embodiment differs from the first embodiment in that the bottom end (79) of one bag (70) partially overlaps the opening end (78) of the adjacent bag (70). The weakening line (36) is then advantageously located in the paper strip (90) in the area of ​​the partial overlap of the adjacent bag (70). In this section, the paper strip is preferably not connected to the outer surfaces of the partially overlapping bags. In the embodiments shown in Figures 3b and 3c, the paper strip (90) also suitably has a width that is less than one-quarter of the width of the paper bags (70).

[0081] Figure 4 shows a view of the front of a section of a bag strand (1") according to a third embodiment of the invention in its uncoiled state. In Figure 4, the beginning and end of the strand are indicated by reference numerals (2) and (4), but are not explicitly shown. The bag strand (1") according to the invention comprises a plurality of bags (10) connected in pairs. In Figure 4, two connected bags (10) of the bag strand (1) are shown in full, and two bags are indicated in sections. The bag strand (1") shown or indicated in Figure 4 is formed from a plurality of sequentially arranged paper bags (70), each with a front wall (72) having an inner and an outer surface (73, 74) and a back wall (75) having an inner and an outer surface (76, 77) and a closed bottom end (79) and an open opening end (78).The bottom end (79) of one bag (70) faces the opening end (78) of the adjacent bag (70). The third embodiment of the bag strand (1") according to the invention, shown in Figure 4, further comprises a plurality of paper web sections (80) with a first side edge (82) and an opposite second side edge (84). In the illustrated embodiment, these paper web sections (80) are connected in a first section (86), which extends from the first side edge (82) to the opposite second side edge (84), to the outside (77) of the back wall (75) of one bag (70) at the bottom end (79), and in a second section (88), which extends from the first side edge (82) to the opposite second side edge (84), to the outside (77) of the back wall (75) of the adjacent bag (70) at the opening end (78).These paper web sections (80) each have a weakening line (36) extending from the first side edge (82) to the opposite second side edge (84). The inner or outer surface (81, 83) of the paper web sections (80) can be coated with a cold-seal adhesive, in particular, in the area between the weakening line (36) and the adjacent bottom end (79) of the paper bag (70). In this way, the bottom area can be reinforced by folding over and bonding it to the outer surface of the front panel.

[0082] Particularly advantageous are embodiments in which, alternatively or additionally, the section between the weakening line (36) and the adjacent opening-side end (78) of the paper bag (70) is equipped with, in particular, cold-seal adhesive. In this way, the opening-side end can be sealed by folding it over and adhering it to the outside of the pre-wall.

[0083] The features of the invention disclosed in the foregoing description, in the claims and in the drawings may be essential for the realization of the invention in its various embodiments, both individually and in any combination.
