Definitions
- the present invention relates to packs for containing at least three cylindrical hygiene articles, in particular packs for at least three uncompressed toilet paper rolls, household towel rolls, kitchen paper rolls or other tissue paper rolls.
- Packs of this kind are also known in the field of other hygiene products that are wound onto rolls, in particular kitchen towels and household towels. Due to the greater axial extension of these rolls, the rolls are typically arranged parallel to one another, particularly in single layer or double layer arrangements. In other words, packs of 1x2, 1x3, 1x4, 2x2 or 2x4 kitchen towels or household towels are customary. However, other configurations for containing up to 16 rolls of kitchen towels or household towels are also widely used.
- the packaging material of these packs is usually made of a plastic film material, in particular a substantially transparent plastic film material, on which product designations, trade names, trademark designations, decorations or the like can be printed.
- the packs are easy to carry and to handle and have an appealing appearance when being carried in the streets or stored at home.
- packaging apparatus and packaging material that is already used in the packaging lines and that does not require major restructuring of the packaging lines. Additionally, it is preferred using simple bags having low manufacturing costs.
- GB 2 380 178 A relates to the packaging of rolls of sheet material in which containers are seated in the hollow spaces of the winding rolls, or between the respective rolls. According to this disclosure, the rolls may be wrapped to form a pack.
- US 5,735,106 relates to a continuous process for packaging and compressing products, in particular tissue paper rolls in a cylindrical sleeve.
- EP 0 279 770 A2 relates to a package comprising a wrapper formed from a single web of flexible sheet material formed into a tube having overlapping edge margins sealed together to form a single longitudinal seam for the tube lying substantially in the plane of one wall of the package, and a pair of end seals at opposite ends of the package, at least one end seal comprising end portions of two opposite walls of the tube sealed together in face-to-face relation in a plane extending longitudinally of the tube and generally at right angles to the plane of the overlapping edge margins forming the longitudinal seam.
- an object of the present invention is to provide a pack for containing cylindrical hygiene articles resulting in reduced pallet space, reduced manufacturing cost and an improved appearance of the printed faces of the pack, and which is easy to open.
- the pack for containing at least three cylindrical hygiene articles in particular at least three uncompressed toilet paper rolls, kitchen paper rolls, household towels or other tissue paper rolls, comprises a bag for containing the hygiene products. Furthermore, the at least three substantially cylindrical hygiene articles are arranged in a substantially triangular arrangement in the bag, wherein the pack is closed by a welding seam extending in a plane substantially perpendicular to a winding axis defined by at least one of the cylindrical hygiene articles.
- Bags may be produced from a tube-like material by simple welding in the cross-direction of the tube-like material.
- the processing and packaging lines of the tissue paper manufacturers are usually made for processing these bags such that investments in additional equipment can be basically avoided.
- the arrangement of the at least three basically cylindrical hygiene articles in a substantially triangular form in the bag has more than one beneficial effect.
- the space needed on a shipping pallet e.g. a Euro pallet
- the cylindrical objects namely the toilet paper rolls or kitchen paper rolls
- the respective rolls are situated out of phase with respect to one another.
- the cylindrical rolls have a round footprint
- a shifting of the rolls with respect to one another, in particular by half of the diameter leads to a considerable saving of pallet space as the rolls can use the groove between them more efficiently.
- the outer walls of the bag do typically have three faces, or sides, typically of the same size. On these three different faces a print can be applied enabling a brilliant and large-area print application.
- an isosceles triangle results, at least in the plane perpendicular to the winding axes of the hygiene articles.
- the three faces visible on the outside of the pack have basically the same dimensions.
- the angle of 60° of the three faces with respect to one another is also beneficial if the packs are placed in a display in a supermarket, as the faces are always visible from the outside, independent of the orientation in which the pack is placed in a shelf, provided the pack is placed on its bottom or top wall.
- the pack is also easier to carry as it does not have such a long vertical extension, which is particularly advantageous for smaller persons.
- the term "triangular" with respect to the arrangement of the cylindrical hygiene articles is to be understood such that the winding axes of the hygiene articles are situated such that they constitute the three corners of the triangle. This arrangement is independent of the layer in which the hygiene articles are situated. In particular, it is also understood that a triangular arrangement is present if the winding axes of an arrangement of cylindrical hygiene articles in a first layer in combination with the winding axes of cylindrical hygiene articles of a second layer constitute the corners of a triangle.
- cylindrical in connection with hygiene articles relates to hygiene articles which are distributed in rollform, in particular toilet paper rolls, household towel rolls or kitchen paper rolls, which may have a basically hollow winding core or, in different embodiments, have no such core at all but are wound fully or are provided as coreless rolls.
- bag will be understood to embrace all types of bags. Bags have the character of providing a volume into which the hygiene products can be filled. Bags are typically pre-manufactured by using a tube-like film material, a folded film material or two webs of film material, the respective layers of the film material being joined together on an appropriate number of edges in order to form the bag, leaving open only one single side of the pre-manufactured bag.
- bag is, inter alia, in contrast to the term “wrapper” which are provided in the form of a single layer of flat film material which is wrapped around the already arranged hygiene products and is then attached to itself in order to close in the hygiene products.
- the film material polypropylene films, polyethylene films, starch based films, biodegradable films and/or material mixtures thereof.
- a shrink film material may also be used.
- the packaging material may be provided in the form of different layers of material, in particular as a multi-layer film and/or a laminate.
- the hygiene products that can be contained in the pack include, but are not limited to, toilet paper rolls, kitchen paper rolls, household towel rolls, napkins, facials, hand wiping towels, object wiping rolls and any other suitable hygiene product for personal hygiene or for object wiping and cleaning, as long as it is provided in cylindrical form/roll form. It will be appreciated that also the comparatively big rolls used in public or professional dispensers may be the hygiene products contained in the pack. In a preferred embodiment, the hygiene products themselves are also contained in an individual packaging, in particular in the form of individual rolls wrapped in paper or in a plastic film material.
- the pack has a handle attached to the tope side of the bag, preferably integrated with the welding seam, or integrated into one of the sides/faces of the bag.
- the handle is particularly advantageous in carrying the pack easily and has, in the integrated form, the advantage of low manufacturing costs.
- the winding axes of the cylindrical hygiene articles are arranged such that they substantially constitute the three corners of a triangle, in particular of an isosceles triangle. It might be possible that the winding axes of the cylindrical hygiene articles are situated substantially parallel to one another. By these features, particularly beneficial pack sizes may be obtained.
- the hygiene articles are arranged in at least two layers, the winding axes of the hygiene articles of the first layer being parallel to the winding axes of the hygiene articles of the second layer.
- the winding axes of the first layer and the winding axes of the second layer of the hygiene articles are displaced with respect to one another to form at least one triangular arrangement.
- the hygiene articles are phase-shifted with respect to one another, in particular by half of the diameter of the cylindrical hygiene articles.
- This specific embodiment enables a close packing as the grooves between the cylindrical hygiene products are filled up with the next layer of hygiene products.
- the hygiene articles are arranged in at least two layers, wherein the winding axes of the hygiene articles of each layer are parallel to one another and are arranged in a triangular form.
- another preferred form of a packing arrangement is provided.
- a handle is attached to the bag, wherein the handle extends substantially parallel to the winding axes of the hygiene articles.
- a handle extends basically orthogonal to the winding axes and intersects with at least one of the winding axes.
- the outer shape of the pack is important for several reasons. First of all, the outer form aids in the provision of printing faces and provides an individual and aesthetic appearance. Second of all, it aids in finding advanced palleting solutions for packing a plurality of packs on a pallet in a space-saving manner. Accordingly, the pack may have the outer form of a prism, in particular a triangular prism. In another embodiment, the pack has the outer form of a wedge. In yet another embodiment, the pack has the outer form of a substantially pyramidal, conical and/or tapering arrangement. For all these outer forms, an exceptionally close packing scheme can be established, leading to a highly efficient packing of the pallets.
- an opening section is provided, which is defined by lines of weakness in the material of the bag, wherein the opening section extends over at least two walls of the pack.
- the opening section may be opened easily when a handle is provided which extends into the opening section and which constitutes a gripping section, in particular having a finger hole.
- a separate handle may be attached to the bag, wherein a first section of the handle is attached to the bag in a bottom wall and a second section of the handle is attached to the bag in an opening section such that the second section of the handle can be used for aiding in opening the opening section.
- a re-closable tab means may be provided for closing the pack after it has been opened.
- the pack is designed for comprising a specially designed opening flap for opening the pack more easily.
- a first end section and a second end section of the bag material are overlapped in an overlapping area and a printed area extends into the first end section and/or the second end section in the overlapping area.
- at least one line of weakness in particular a perforation, extends into the first end section and/or the second end section substantially within the boundaries of the printed area, wherein the first end section and the second end section are joined to one another in the overlapping area outside the boundaries of the printed area.
- the overlap is typically not joined such that a gripping section can be provided which can be easily gripped by an end customer.
- the overlapping area is situated in at least one of the side walls, preferably extending between two side walls in order to provide an opening flap in the side walls.
- the objective is also solved by a method for manufacturing a pack according to the present disclosure.
- the method comprises the steps of providing a first layer of hygiene articles by placing at least two columns of hygiene articles next to one another and providing at least a second layer of hygiene articles on top of the first layer of hygiene articles by placing at least one column of hygiene articles in the groove between the two columns of the first layer.
- a bag is held open in a substantially triangular form using at least two vacuum grippers which are operated under an angle.
- the triangular arrangement of the hygiene articles is inserted into the opened bag and the bag is closed by at least two folding blades which are operated under an angle. Then, the folded material is heat welded such that the bag is sealed tightly.
- Figure 1 shows a pack 1 according to the present disclosure in a schematic view plan view from the bottom of the pack. In other words, the bottom wall 20 of the pack 1 is shown.
- the pack 1 is comprised of a bag 2 for containing the hygiene products 3, wherein the bag 2 is made from a polyethylene material.
- the bag 2 shown in the Figure is a so-called flat bag, meaning that it is basically manufactured from a tube-like plastics foil material which carries a seal in the cross direction to seal together both layers of the tube in order to close a top part 28 of the flat bag.
- the bottom wall 20 shown in Figure 1 is the wall that sits in the position through which the hygiene articles 3 are introduced into the bag 2 before it is sealed off at a welding seam 4.
- the welding seam 4 extends in a plane substantially perpendicular to the winding axes 32 of the cylindrical hygiene products 3. This welding seam 4 is situated in this plane such that a bag 2 can be used for manufacturing the pack 1.
- the hygiene articles 3 are arranged basically in a triangular arrangement, as can be seen in Figure 1 .
- the winding axes 32 of the toilet paper rolls are situated in the center of the toilet paper rolls, virtually within the winding cores 30.
- the winding axes 32 of the toilet paper rolls 3 are, in the embodiment shown in Figure 1 , in a parallel arrangement.
- the three winding axes 32 of the toilet paper rolls 3 are arranged such that they constitute the corners of an triangle, in particular of an isosceles triangle.
- the bag 2 used may also be a different type of bag, in particular a cylindrical bag, a bottom folding bag, a side folding bag, a shrink film bag or any other suitable type of bag. It will be understood that in all types of bags the top part is the closed part that is pre-manufactured and that has the specific forms.
- top side and bottom wall of the bag in the disclosure, it is to be understood that the terms “top” and “bottom” are not considered limiting and any other combination of walls can be used, provided that the first side is a pre-sealed side of the bag and the second wall is sealed off after the hygiene products are inserted into the bag.
- a triangular arrangement is also defined by the pyramidal form of the pack.
- the base of the packs is wider than the tip, resulting in a pyramidal, or conical, outer form of the packs.
- the bottom wall 20 of the pack 1 comprises two flaps 202 and 204 which result from the simple form of the bag 2 in its initial form, namely the bag configuration which leads to some excess material that needs to be folded into the center of the bottom wall.
- the flaps 202 and 204 of bag 2 stand up after filling the bag 2.
- These flaps 202 and 204 have to be folded into the bottom wall 20 of the pack 1 in order to close the pack.
- the process of folding in the flaps 202 and 204 will be explained below, in particular with respect to Figures 17 and 18 .
- the resulting flaps 202 and 204 do, accordingly, remain on the bottom wall 20 of the pack 1.
- FIG. 2 A schematic perspective view of the pack according to Figure 1 is shown in Figure 2 . It becomes immediately apparent that the three side walls 22, 24 and 26 have basically the same size, owing to the fact that the three hygiene articles in the form of the toilet paper rolls 3 have the same outer dimensions.
- the winding axes 32 of the toilet paper rolls 3 are arranged in a triangular form as mentioned above, i.e. the winding axes constitute the three corners of a triangle.
- three toilet paper rolls are basically aligned in a "column" such that the winding axes 32 of the three toilet paper rolls 3 of the respective columns fall substantially together. Accordingly, the three columns of toilet paper rolls 3 are then arranged in a form according to the triangular arrangement of the winding axes of the toilet paper rolls 3.
- the top wall 28 of the pack which is not directly visible in Figure 2 due to the perspective, is the wall that was manufactured before the hygiene articles 3 were inserted into the bag 2.
- the top wall 28 carries the single weld that constitutes the bag in the beginning.
- FIG 3 shows another embodiment of a pack 1 which is basically identical to the pack shown in Figures 1 and 2 but, additionally, carries a handle 5 situated in one of the side walls, namely in side wall 22.
- the handle 5 has a finger hole 50 which enables the end consumer to carry the pack 1 conveniently.
- Figure 4 shows yet another embodiment of the pack 1 which has also a basically identical outer shape as that shown in Figures 1 and 2 , but a handle 5 with a finger hole 50 is applied to the top wall 28.
- the handle 5 and the top wall 28 can be manufactured during the manufacture of the bag 2 itself, before the hygiene articles 3 are filled into the bag.
- top wall 28 and the bottom wall 20 have both a substantially triangular shape and the side walls 22, 24 and 26 extend between a translation of these two triangles basically in a plane.
- Wedge-shaped and prism-shaped does not imply necessarily that the corners of the respective triangles are sharp. In fact, the corners are rather rounded due to the cylindrical form of the hygiene articles 3. It will be appreciated, however, that even though there are no sharp corners, the overall appearance of the top wall 28 as well as the bottom wall 20 is triangular.
- Figure 5 shows another pack 1 having four hygiene articles 3 enclosed therein.
- the arrangement of the hygiene articles in the form of the toilet paper rolls 3 is such that the lower layer of the hygiene articles is arranged such that the winding axes 32 of the hygiene articles are parallel to one another and constitute the three points of a triangle.
- a single toilet paper roll is placed on top of the bottom layer such that the winding axis 32 of the second layer toilet paper roll 3 is exactly placed in the middle of the three winding axes of the lower layer.
- the pack results in a rather pyramidal-shaped form. This form implies that the base of the pack is wider than the top/tip. A handle 5 is placed on top of the pack.
- an opening section 6 is provided and defined by a perforation line 60 around the opening section 6.
- the opening section 6 enables the end customer to open the pack 1 easily and at a defined position of the pack.
- the arrangement of the different toilet paper rolls 3 according to Figure 5 is such that they are all phase-shifted with respect to one another.
- the four toilet paper rolls 3 are arranged such that they take up as little volume as possible.
- Figure 6 shows another pack 1 for containing three toilet paper rolls 3.
- the winding axes 32 of the individual toilet paper rolls 3 are arranged parallel to one another and constitute a triangle.
- the bag 2 is basically made in the same manner as that shown in Figures 1 to 4 and it can be imagined that the pack according to Figure 6 is basically a slice of the bags shown in Figures 2 to 4 .
- a handle 5 is provided in one of the corners of the pack. Furthermore, an opening section 6 defined by a perforation 60 is also present.
- the perforation 60 extends into the handle 5, constituting a gripping section 62 with a finger hole 64, which can be used for opening the opening section 6 by gripping it and ripping the pack apart.
- FIG 10 shows yet another embodiment of a pack 1, this pack containing six hygiene articles, again in a triangular form.
- An opening section 6 is defined by a perforation 60 in the bag 2.
- a first carrying handle 5 is provided, which extends from one of the side walls 22 to the other of the side walls 24 and serves to carry the pack 1 in an upright position.
- a second handle 52 is provided, basically in a plane perpendicular to the plane constituted by the first handle 5, wherein the second handle 52 extends from a first section 520 which is attached to the bottom wall 20 of the pack 1 towards a second section 522, which is attached to the top wall 28 of the pack.
- the second section 522 is attached to the foil material of the bag 2 in the area of the opening section 6. Accordingly, the second handle 52 can be used as an aid for opening the opening section 6 by pulling the handle 52 such that a force is effected on the opening section 6.

Description
- The present invention relates to packs for containing at least three cylindrical hygiene articles, in particular packs for at least three uncompressed toilet paper rolls, household towel rolls, kitchen paper rolls or other tissue paper rolls.
- It is known to fill hygiene products for distribution, presentation and for retailing to the end customer into packs, in particular into flexible packs made from a plastic film material. The packs are usually made such that an appropriate number of hygiene products can be retailed to the customer. For example, rolls of toilet paper are often supplied to the end customer in packs of 1x2, 2x2, 2x5, 2x4, 3x3, 4x3 or 4x5 rolls. However, other configurations for containing up to 25 toilet paper rolls are also widely used. Typically, the rolls are arranged in these packs in single, double or triple layer arrangements such that the respective winding axes of the toilet paper rolls of a layer are situated in the plane defined by the layer and the winding axes are substantially parallel to one another. In other typical packs, the winding axes of the toilet paper rolls of one layer are parallel to one another but extend substantially perpendicular to the plane defined by the layer such that the winding axes represent the nodes of a substantially perpendicular grid.
- Packs of this kind are also known in the field of other hygiene products that are wound onto rolls, in particular kitchen towels and household towels. Due to the greater axial extension of these rolls, the rolls are typically arranged parallel to one another, particularly in single layer or double layer arrangements. In other words, packs of 1x2, 1x3, 1x4, 2x2 or 2x4 kitchen towels or household towels are customary. However, other configurations for containing up to 16 rolls of kitchen towels or household towels are also widely used.
- The packaging material of these packs is usually made of a plastic film material, in particular a substantially transparent plastic film material, on which product designations, trade names, trademark designations, decorations or the like can be printed.
- In the field of developing packs for hygiene articles, many conflicting objectives have to be observed.
- From the logistics point of view, it is important to provide a pack that saves pallet space and, thus, reduces the cost of shipping. In particular for hygiene articles, a large proportion of the volume occupied by the hygiene articles is made up from air as the hygiene articles have a substantially hollow winding core and cannot be stacked too tightly due to their cylindrical form. This is in particular the case when it comes to uncompressed hygiene articles such as toilet paper rolls and kitchen and household paper rolls. Accordingly, new packaging solutions also aim to increase the density of the hygiene articles per shipping volume.
- From a customer point of view, it is desirable that the packs are easy to carry and to handle and have an appealing appearance when being carried in the streets or stored at home.
- From a marketing point of view, it is preferred to have the possibility of imprinting on the pack walls the trade name and customer information such that as large as possible areas are provided which are preferably unwrinkled, enabling a spotless print appearance.
- From a manufacturing costs point of view, it is preferred to use packaging apparatus and packaging material that is already used in the packaging lines and that does not require major restructuring of the packaging lines. Additionally, it is preferred using simple bags having low manufacturing costs.
- All these conflicting issues have to be considered when developing a new pack design.
-
GB 2 380 178 A -
US 5,735,106 relates to a continuous process for packaging and compressing products, in particular tissue paper rolls in a cylindrical sleeve. -
EP 0 279 770 A2 relates to a package comprising a wrapper formed from a single web of flexible sheet material formed into a tube having overlapping edge margins sealed together to form a single longitudinal seam for the tube lying substantially in the plane of one wall of the package, and a pair of end seals at opposite ends of the package, at least one end seal comprising end portions of two opposite walls of the tube sealed together in face-to-face relation in a plane extending longitudinally of the tube and generally at right angles to the plane of the overlapping edge margins forming the longitudinal seam. - On the basis of the aforementioned prior art and the design constraints mentioned, an object of the present invention is to provide a pack for containing cylindrical hygiene articles resulting in reduced pallet space, reduced manufacturing cost and an improved appearance of the printed faces of the pack, and which is easy to open.
- This object is solved by a pack comprising the features of claim 1. Preferred embodiments are defined in the dependent claims.
- According to the present disclosure, the pack for containing at least three cylindrical hygiene articles, in particular at least three uncompressed toilet paper rolls, kitchen paper rolls, household towels or other tissue paper rolls, comprises a bag for containing the hygiene products. Furthermore, the at least three substantially cylindrical hygiene articles are arranged in a substantially triangular arrangement in the bag, wherein the pack is closed by a welding seam extending in a plane substantially perpendicular to a winding axis defined by at least one of the cylindrical hygiene articles.
- The advantage of using a bag for containing the hygiene products is, inter alia, a cost issue. Bags may be produced from a tube-like material by simple welding in the cross-direction of the tube-like material. The processing and packaging lines of the tissue paper manufacturers are usually made for processing these bags such that investments in additional equipment can be basically avoided.
- The arrangement of the at least three basically cylindrical hygiene articles in a substantially triangular form in the bag has more than one beneficial effect. In particular, the space needed on a shipping pallet, e.g. a Euro pallet, is considerably reduced as the cylindrical objects, namely the toilet paper rolls or kitchen paper rolls, can be packed more densely. This is due to the fact that the respective rolls are situated out of phase with respect to one another. As the cylindrical rolls have a round footprint, a shifting of the rolls with respect to one another, in particular by half of the diameter, leads to a considerable saving of pallet space as the rolls can use the groove between them more efficiently.
- Furthermore, due to the arrangement of at least three hygiene articles in the triangular form, the outer walls of the bag do typically have three faces, or sides, typically of the same size. On these three different faces a print can be applied enabling a brilliant and large-area print application.
- Due to the triangular arrangement and the typically identical size of the individual hygiene articles, an isosceles triangle results, at least in the plane perpendicular to the winding axes of the hygiene articles. In other words, the three faces visible on the outside of the pack have basically the same dimensions. The angle of 60° of the three faces with respect to one another is also beneficial if the packs are placed in a display in a supermarket, as the faces are always visible from the outside, independent of the orientation in which the pack is placed in a shelf, provided the pack is placed on its bottom or top wall.
- Due to the higher packaging density within the pack, the pack is also easier to carry as it does not have such a long vertical extension, which is particularly advantageous for smaller persons.
- In the description, the term "triangular" with respect to the arrangement of the cylindrical hygiene articles is to be understood such that the winding axes of the hygiene articles are situated such that they constitute the three corners of the triangle. This arrangement is independent of the layer in which the hygiene articles are situated. In particular, it is also understood that a triangular arrangement is present if the winding axes of an arrangement of cylindrical hygiene articles in a first layer in combination with the winding axes of cylindrical hygiene articles of a second layer constitute the corners of a triangle.
- The term "cylindrical" in connection with hygiene articles relates to hygiene articles which are distributed in rollform, in particular toilet paper rolls, household towel rolls or kitchen paper rolls, which may have a basically hollow winding core or, in different embodiments, have no such core at all but are wound fully or are provided as coreless rolls.
- Throughout the description, the term "bag" will be understood to embrace all types of bags. Bags have the character of providing a volume into which the hygiene products can be filled. Bags are typically pre-manufactured by using a tube-like film material, a folded film material or two webs of film material, the respective layers of the film material being joined together on an appropriate number of edges in order to form the bag, leaving open only one single side of the pre-manufactured bag. The term "bag" is, inter alia, in contrast to the term "wrapper" which are provided in the form of a single layer of flat film material which is wrapped around the already arranged hygiene products and is then attached to itself in order to close in the hygiene products.
- It is preferred to use for the film material polypropylene films, polyethylene films, starch based films, biodegradable films and/or material mixtures thereof. A shrink film material may also be used. The packaging material may be provided in the form of different layers of material, in particular as a multi-layer film and/or a laminate.
- The hygiene products that can be contained in the pack include, but are not limited to, toilet paper rolls, kitchen paper rolls, household towel rolls, napkins, facials, hand wiping towels, object wiping rolls and any other suitable hygiene product for personal hygiene or for object wiping and cleaning, as long as it is provided in cylindrical form/roll form. It will be appreciated that also the comparatively big rolls used in public or professional dispensers may be the hygiene products contained in the pack. In a preferred embodiment, the hygiene products themselves are also contained in an individual packaging, in particular in the form of individual rolls wrapped in paper or in a plastic film material.
- In a preferred embodiment, the pack has a handle attached to the tope side of the bag, preferably integrated with the welding seam, or integrated into one of the sides/faces of the bag. The handle is particularly advantageous in carrying the pack easily and has, in the integrated form, the advantage of low manufacturing costs.
- In a preferred arrangement, the winding axes of the cylindrical hygiene articles are arranged such that they substantially constitute the three corners of a triangle, in particular of an isosceles triangle. It might be possible that the winding axes of the cylindrical hygiene articles are situated substantially parallel to one another. By these features, particularly beneficial pack sizes may be obtained.
- In an alternative embodiment, the hygiene articles are arranged in at least two layers, the winding axes of the hygiene articles of the first layer being parallel to the winding axes of the hygiene articles of the second layer. The winding axes of the first layer and the winding axes of the second layer of the hygiene articles are displaced with respect to one another to form at least one triangular arrangement.
- In order to decrease the pack size even further, the hygiene articles are phase-shifted with respect to one another, in particular by half of the diameter of the cylindrical hygiene articles. This specific embodiment enables a close packing as the grooves between the cylindrical hygiene products are filled up with the next layer of hygiene products.
- Preferably, the hygiene articles are arranged in at least two layers, wherein the winding axes of the hygiene articles of each layer are parallel to one another and are arranged in a triangular form. In this embodiment, another preferred form of a packing arrangement is provided.
- In order to enable easy carrying of the pack, a handle is attached to the bag, wherein the handle extends substantially parallel to the winding axes of the hygiene articles. In an alternative, a handle extends basically orthogonal to the winding axes and intersects with at least one of the winding axes.
- The outer shape of the pack is important for several reasons. First of all, the outer form aids in the provision of printing faces and provides an individual and aesthetic appearance. Second of all, it aids in finding advanced palleting solutions for packing a plurality of packs on a pallet in a space-saving manner. Accordingly, the pack may have the outer form of a prism, in particular a triangular prism. In another embodiment, the pack has the outer form of a wedge. In yet another embodiment, the pack has the outer form of a substantially pyramidal, conical and/or tapering arrangement. For all these outer forms, an exceptionally close packing scheme can be established, leading to a highly efficient packing of the pallets.
- In order to aid the customer in the process of opening the pack, an opening section is provided, which is defined by lines of weakness in the material of the bag, wherein the opening section extends over at least two walls of the pack. The opening section may be opened easily when a handle is provided which extends into the opening section and which constitutes a gripping section, in particular having a finger hole.
- In another embodiment, a separate handle may be attached to the bag, wherein a first section of the handle is attached to the bag in a bottom wall and a second section of the handle is attached to the bag in an opening section such that the second section of the handle can be used for aiding in opening the opening section.
- To be able to re-close the opening section after hygiene articles have been withdrawn, a re-closable tab means may be provided for closing the pack after it has been opened.
- In a further preferred embodiment, the pack is designed for comprising a specially designed opening flap for opening the pack more easily. In this embodiment, a first end section and a second end section of the bag material are overlapped in an overlapping area and a printed area extends into the first end section and/or the second end section in the overlapping area. Furthermore, at least one line of weakness, in particular a perforation, extends into the first end section and/or the second end section substantially within the boundaries of the printed area, wherein the first end section and the second end section are joined to one another in the overlapping area outside the boundaries of the printed area. In the printed area, the overlap is typically not joined such that a gripping section can be provided which can be easily gripped by an end customer. In a preferred embodiment, the overlapping area is situated in at least one of the side walls, preferably extending between two side walls in order to provide an opening flap in the side walls.
- The objective is also solved by a method for manufacturing a pack according to the present disclosure. The method comprises the steps of providing a first layer of hygiene articles by placing at least two columns of hygiene articles next to one another and providing at least a second layer of hygiene articles on top of the first layer of hygiene articles by placing at least one column of hygiene articles in the groove between the two columns of the first layer. In a further step a bag is held open in a substantially triangular form using at least two vacuum grippers which are operated under an angle. The triangular arrangement of the hygiene articles is inserted into the opened bag and the bag is closed by at least two folding blades which are operated under an angle. Then, the folded material is heat welded such that the bag is sealed tightly.

Figure 1 shows a pack 1 according to the present disclosure in a schematic view plan view from the bottom of the pack. In other words, thebottom wall 20 of the pack 1 is shown. - The pack 1 is comprised of a
bag 2 for containing thehygiene products 3, wherein thebag 2 is made from a polyethylene material. Thebag 2 shown in the Figure is a so-called flat bag, meaning that it is basically manufactured from a tube-like plastics foil material which carries a seal in the cross direction to seal together both layers of the tube in order to close atop part 28 of the flat bag. Thebottom wall 20 shown inFigure 1 , however, is the wall that sits in the position through which thehygiene articles 3 are introduced into thebag 2 before it is sealed off at awelding seam 4. - The
welding seam 4 extends in a plane substantially perpendicular to the windingaxes 32 of thecylindrical hygiene products 3. Thiswelding seam 4 is situated in this plane such that abag 2 can be used for manufacturing the pack 1. - The
hygiene articles 3 are arranged basically in a triangular arrangement, as can be seen inFigure 1 . - By the term "triangular arrangement", the following is understood: the winding
axes 32 of the toilet paper rolls are situated in the center of the toilet paper rolls, virtually within the windingcores 30. The winding axes 32 of the toilet paper rolls 3 are, in the embodiment shown inFigure 1 , in a parallel arrangement. Furthermore, the three windingaxes 32 of the toilet paper rolls 3 are arranged such that they constitute the corners of an triangle, in particular of an isosceles triangle. - It will be appreciated that the
bag 2 used may also be a different type of bag, in particular a cylindrical bag, a bottom folding bag, a side folding bag, a shrink film bag or any other suitable type of bag. It will be understood that in all types of bags the top part is the closed part that is pre-manufactured and that has the specific forms. - Even though reference is made to a "top side" and a "bottom wall" of the bag in the disclosure, it is to be understood that the terms "top" and "bottom" are not considered limiting and any other combination of walls can be used, provided that the first side is a pre-sealed side of the bag and the second wall is sealed off after the hygiene products are inserted into the bag.
- In alternative embodiments, shown also schematically in
Figures 5, 7 and8 below, a triangular arrangement is also defined by the pyramidal form of the pack. In these arrangements, the base of the packs is wider than the tip, resulting in a pyramidal, or conical, outer form of the packs. - Returning to
Figure 1 , thebottom wall 20 of the pack 1 comprises twoflaps bag 2 in its initial form, namely the bag configuration which leads to some excess material that needs to be folded into the center of the bottom wall. In particular, as a bag having no specified extension in a direction perpendicular to the plane of the bag is used and the final shape of the pack 1 is a triangular pack, theflaps bag 2 stand up after filling thebag 2. Theseflaps bottom wall 20 of the pack 1 in order to close the pack. The process of folding in theflaps Figures 17 and 18 . The resulting flaps 202 and 204, do, accordingly, remain on thebottom wall 20 of the pack 1. - A schematic perspective view of the pack according to
Figure 1 is shown inFigure 2 . It becomes immediately apparent that the threeside walls - In the embodiment shown in
Figure 2 , nine toilet paper rolls are arranged in the triangular form. In other words, the windingaxes 32 of the toilet paper rolls 3 are arranged in a triangular form as mentioned above, i.e. the winding axes constitute the three corners of a triangle. However, three toilet paper rolls are basically aligned in a "column" such that the windingaxes 32 of the three toilet paper rolls 3 of the respective columns fall substantially together. Accordingly, the three columns of toilet paper rolls 3 are then arranged in a form according to the triangular arrangement of the winding axes of the toilet paper rolls 3. - The
top wall 28 of the pack, which is not directly visible inFigure 2 due to the perspective, is the wall that was manufactured before thehygiene articles 3 were inserted into thebag 2. In other words, thetop wall 28 carries the single weld that constitutes the bag in the beginning. - From
Figure 2 it can also be seen that in the three side walls (faces) 22, 24 and 26, substantially no folding of the material occurs. Accordingly, on all threeside walls -
Figure 3 shows another embodiment of a pack 1 which is basically identical to the pack shown inFigures 1 and 2 but, additionally, carries ahandle 5 situated in one of the side walls, namely inside wall 22. Thehandle 5 has afinger hole 50 which enables the end consumer to carry the pack 1 conveniently. -
Figure 4 shows yet another embodiment of the pack 1 which has also a basically identical outer shape as that shown inFigures 1 and 2 , but ahandle 5 with afinger hole 50 is applied to thetop wall 28. Thehandle 5 and thetop wall 28 can be manufactured during the manufacture of thebag 2 itself, before thehygiene articles 3 are filled into the bag. - The packs shown in
Figures 2 to 4 have in common that the outer shape of the bag, even though it was a bag before thehygiene articles 3 are filled into the bag, has now, after thehygiene articles 3 are placed into thebag 2, a wedge-shaped or prism-shaped outer form. - The terms "wedge" and "prism" are understood in this connection to mean that the
top wall 28 and thebottom wall 20 have both a substantially triangular shape and theside walls - Wedge-shaped and prism-shaped does not imply necessarily that the corners of the respective triangles are sharp. In fact, the corners are rather rounded due to the cylindrical form of the
hygiene articles 3. It will be appreciated, however, that even though there are no sharp corners, the overall appearance of thetop wall 28 as well as thebottom wall 20 is triangular. -
Figure 5 shows another pack 1 having fourhygiene articles 3 enclosed therein. - Here, the arrangement of the hygiene articles in the form of the toilet paper rolls 3 is such that the lower layer of the hygiene articles is arranged such that the winding
axes 32 of the hygiene articles are parallel to one another and constitute the three points of a triangle. - In the second layer, a single toilet paper roll is placed on top of the bottom layer such that the winding
axis 32 of the second layertoilet paper roll 3 is exactly placed in the middle of the three winding axes of the lower layer. - As can be seen in
Figure 5 , the pack results in a rather pyramidal-shaped form. This form implies that the base of the pack is wider than the top/tip. Ahandle 5 is placed on top of the pack. - Furthermore, an
opening section 6 is provided and defined by aperforation line 60 around theopening section 6. Theopening section 6 enables the end customer to open the pack 1 easily and at a defined position of the pack. - As may be appreciated, the arrangement of the different toilet paper rolls 3 according to
Figure 5 is such that they are all phase-shifted with respect to one another. In other words, the four toilet paper rolls 3 are arranged such that they take up as little volume as possible. -
Figure 6 shows another pack 1 for containing three toilet paper rolls 3. Here, again, the windingaxes 32 of the individual toilet paper rolls 3 are arranged parallel to one another and constitute a triangle. Thebag 2 is basically made in the same manner as that shown inFigures 1 to 4 and it can be imagined that the pack according toFigure 6 is basically a slice of the bags shown inFigures 2 to 4 . - In the embodiment shown in
Figure 6 , ahandle 5 is provided in one of the corners of the pack. Furthermore, anopening section 6 defined by aperforation 60 is also present. Theperforation 60 extends into thehandle 5, constituting a grippingsection 62 with afinger hole 64, which can be used for opening theopening section 6 by gripping it and ripping the pack apart. -
Figure 7 shows yet another embodiment of a pack 1. According to this embodiment, five hygiene articles in the form of toilet paper rolls 3 are provided in abag 2. As can be seen from the Figure, the three winding axes 33 are, again, parallel to one another and constitute the outer corners of a triangle. However, in the arrangement shown inFigure 7 , the two lower columns of toilet paper rolls 3 include two hygiene articles each, wherein in the top layer only a single hygiene article is present. Accordingly, the pack according toFig.7 has, again, a form resembling that of a pyramid. Ahandle 5 is provided on one of theside walls 22 of the pack 1. -
Figure 8 shows yet another embodiment of a pack 1 includinghygiene articles 3. In a first layer, fourhygiene articles 3 are situated and in the second layer, two hygiene articles are situated. The winding axes 33 of all hygiene articles are parallel to one another. However, the four hygiene articles in the lower layer are situated such that the four windingaxes 32 constitute the corners of a parallelogram. Furthermore, three of the hygiene articles of the lower layers each constitute with their windingaxes 32 the triangle typical for the packs. In other words, the four toilet paper rolls 3 in the lower layer are arranged in a "diamond"-shape. Ahandle 5 is also present on top of the pack 1 and attached to thebag 2. - Important for all embodiments of the present invention is that the cylindrical hygiene articles, in particular toilet paper rolls of one layer, are arranged such that they are packed in the closest possible packing. This leads to an arrangement in which the winding axes of each three neighbouring rolls having parallel winding axes constitute the three corners of a triangle. This is in stark contrast to the arrangements usually used for cylindrical hygiene articles, in which the winding axes of the respective cylindrical hygiene articles are either arranged in a single plane (e.g. kitchen paper rolls) or are arranged such that they constitute the nodes of a rectangular grid (e.g. toilet paper rolls). The conventional arrangements result in basically rectangular shapes of the packs. Packs in which deliberately a shifting of the hygiene articles occurs in a direction perpendicular to the winding axis of the hygiene articles, in particular such that the axis of neighbouring hygiene articles are shifted with respect to the remaining by half the diameter of the cylindrical roll, are not known.
-
Figure 9 shows another embodiment of the pack 1. Again, nine hygiene articles in the form of toilet paper rolls are included in abag 2, wherein in this view thetop wall 28 is visible. Ahandle 5 is situated in thetop wall 28 as well as anopening section 6 defined by aperforation 60. The perforation extends into the handle, providing agripping section 62 having afinger hole 64 such that the end customer may, by using the grippingsection 62, easily open theopening section 6. -
Figure 10 shows yet another embodiment of a pack 1, this pack containing six hygiene articles, again in a triangular form. Anopening section 6 is defined by aperforation 60 in thebag 2. A first carryinghandle 5 is provided, which extends from one of theside walls 22 to the other of theside walls 24 and serves to carry the pack 1 in an upright position. Asecond handle 52 is provided, basically in a plane perpendicular to the plane constituted by thefirst handle 5, wherein thesecond handle 52 extends from afirst section 520 which is attached to thebottom wall 20 of the pack 1 towards asecond section 522, which is attached to thetop wall 28 of the pack. Thesecond section 522 is attached to the foil material of thebag 2 in the area of theopening section 6. Accordingly, thesecond handle 52 can be used as an aid for opening theopening section 6 by pulling thehandle 52 such that a force is effected on theopening section 6. - It is appreciated, however, that also only one of the handles may be used in the pack 1 of this embodiment. In this respect, the
second handle 52 is of particular interest as it enables the end customer to carry the pack conveniently by using the handle. If it comes to opening the pack, the end customer may use thesecond section 522 of thehandle 52 to open the pack in theopening section 6 in order to withdraw/remove single hygiene products from the packaging. -
Figures 11 to 14 show different arrangements of toilet paper rolls 3 which are all considered to include triangular arrangements of the cylindrical articles.Figures 12 and 13 have also a triangular outer shape in a plane perpendicular to the winding axes. InFigures 11 and 14 , thehygiene articles 3 are arranged in several sections which could be considered to constitute triangles as it is shown schematically inFigure 11 , where the three different triangles are indicted by reference numerals I, II and III. -
Figure 15 shows abag 2 with itsbottom end 20 in a position in which the flaps of thebag 2 are not yet completely folded in and sealed by heat welding. Accordingly, the "ears" of thebag 2 are still shown. - In
Figure 16 , a pack 1 is shown in a different perspective such that thetop wall 28 can be seen, in which ahandle 5 is prefabricated. In this pack 1 a specific opening mechanism is provided, resulting in anopening flap 88. - This
opening flap 88 is formed as follows. In theside wall 22 of thebag 2 an overlappingarea 8 is provided, constituted by overlapping afirst end section 80 and asecond end section 82 of the bag material. A printedarea 84 extends into thefirst end section 80. In order to constitute thebag 2, thefirst end section 80 and thesecond end section 82 are joined to one another in the overlap, e.g. by heat welding. In the printedarea 84, however, joining is prevented by the print such that thefirst end section 80 and thesecond end section 82 are not connected to one another within the boundaries of the printedarea 84, but are only connected to one another in the sections outside the boundaries of the printedarea 84. - Two lines of weakness are provided, in particular in the form of
perforations 86 which also extend into thefirst end section 80. Theperforations 86 are provided inside the boundaries of the printedarea 84. - The
specific opening flap 88 resulting from the above mentioned features can be easily gripped by an end customer in the freely accessiblegripping section 800 and can be easily ripped open along the lines of weakness, resulting in an opening mechanism which is easy to use and easy to understand. - Even though the perforations and the printed area are described in this embodiment as extending both into the first end section, it will be understood that any other combination is also possible, in particular providing the printed area such that it extends into the first end section and providing the perforations such that they extend into the second end section, and vice versa, or both can be provided in the second end section.
- In a preferred embodiment, the printed
area 84 extends in theoverlap 8 only along a specific portion of the overlap, leaving agripping section 800 of theopening flap 88 unattached, but closing off the pack completely. This embodiment is schematically shown inFigure 17 . -
Figure 18 shows schematically a manufacturing process of the pack in which the bag, in which the hygiene articles have been filled in the configuration as described above, now needs to be closed. In particular, thebag 2 shown inFigure 18 was in a position as shown inFigure 15 above, in which theflaps - The
flaps folding blades bag 2 and in particular with theflaps folding blades respective side walls folding blades - After the
flaps folding blades folding blades blades Figure 19 . Thesealing blades bag 2 material occurs and the bag is left over in the closed position. -
Figure 20 shows schematically the opening of thebag 2, which is, as shown inFigure 21 , a typicalflat bag 2 being constituted of a basically tubular material which is heat welded by aweld 40 on one of its ends, leaving a flat pack to be filled. - As shown in
Figure 20 , at least twogrippers bag 2 in a substantially triangular form such that the tissue paper rolls in their triangular arrangement can be inserted into the bag. - It follows, that the following steps are preferably carried out for filing the bag:
- providing a
bag 2 and advancing it into a filling and closing station; - in the filling and closing station, opening up the
bag 2 by at least twovacuum grippers bag 2 in a substantially triangular form; - providing an arrangement of cylindrical hygiene articles in the triangular form;
- advancing the hygiene articles in their triangular arrangement into the opened bag;
- closing the bag by folding in the remaining material of the bag using
folding blades - heat welding and cutting the access material by the
heat welding blades - The provision of the hygiene articles in a triangular form can be achieved, e.g. by arranging, in a first step, a first layer of two "columns" of hygiene articles next to one another. In a second step, placing the third column of hygiene articles in a second layer on top of the first and second column of the hygiene articles, specifically in the groove between the first and the second column. This packaging method results in the embodiments shown above, e.g. in
Figures 1 to 4 ,6 and 7 ,9 and 10 ,15 and 16. Naturally, it is also possible to use another manufacturing method to achieve the specific arrangements. - While only preferred embodiments have been described in terms of particular variations and illustrative figures, those of ordinary skill in the art will recognize that the invention is not limited to the variations or figures described.
- Therefore, it will be understood that various modifications, variations, changes and adaptations will be apparent to those of ordinary skill in the art without departing from the scope of the appended claims.
