Description of Example Embodiments

Abrasive products may be, for example, sanding products for surface finishing of object surface(s) of applications. Suitable object surface(s) may include various materials, such as wood, metal, composites, plastics, minerals or different coatings such as paints or varnishes. Abrasive products may therefore be used for example, in different industries, such as automotive industry, wood and furniture industry, ships and boats, building and construction sites, composites industry as well as in metal finishing industry, to name a few. Common abrasive methods may comprise for example grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping or sanding.

Removal of materials with different properties and behaviour may require different properties from the abrasive product. Abrasive products are manufactured in a wide range of products. There exists abrasive products made of different materials or they have different shapes. One example of abrasive products is an abrasive roll comprising a rolled abrasive product. The rolled abrasive product may consist of a long strip of abrasive product that is rolled, wrapped, around a core. The long strip of abrasive product may be a perforated abrasive product comprising a multiple abrasive product pieces, abrasives, which are linked to one another successively. These abrasives are arranged to be torn off into suitable pieces usually along a perforation between the individual abrasives. The linked abrasives may have different shapes, usually rectangular or circular with a narrow perforated bridge linking the discs. The long strip of abrasive product may also be one, long, uniform, piece of abrasive product. This strip is arranged to be torn off into suitable pieces without perforations.

Abrasive products need to be protected from dirt, dust and abrasive contact with other non-object surfaces in order to maintain their abrasive features; demanding sanding operations require clean and undamaged sanding products. Therefore, the abrasive product, are usually packed for storage, transport and/or use. The package may protect the product from physical damage during storage, transport and use.

Usually in today's abrasive product roll packages the roll of the abrasive product is arranged freely on the bottom of the package. The roll may then move inside the package thus having an abrasive contact(s) with the surface(s) of the package especially during the transport and/or use, for example, when the product is extracted from the package. Therefore, the abrasive product may be damaged in the abrasive product roll package if it is movable inside the package. In the following, several embodiments of the invention will be described in the context of an abrasive product roll package for providing a package that protects the abrasive product or at least its abrasive coated side from contact with the inner surface(s) of the package during storage, transport and/or use. In addition, the abrasive product roll package according to the invention is also user-friendly. The package enables that the rolled product may be extracted, withdrawn, from the package without contact at least by the coated side with the inner surface(s) of the package or with the surface(s) or edge of an extraction slot of the package through which the rolled product is arranged to be extracted from the package. It is to be noted, however, that the invention is not limited to abrasive product rolls only. In fact, material of a product roll may be any material that is advantageous to be protected from unnecessary physical contact and dust.

The abrasive product roll package may comprise two parts, a package body and a lid. The package body comprises an open side and the open side is arranged to be closed by the lid i.e. the lid is arranged to close the package body. The lid is further openable, so that the product can be extracted from the package. The package body and the lid form a package, box, around the roll when they are put together. These two parts may be united by a hinge like a bridge at one side of the package, but the package may also comprise two separate parts. The bridge may be made of the same material as the package body and the lid, but it may also be a separate hinge structure made of some other material. The package body and the lid may also be made of different materials. The lid may be paper based material and the package body may be plastic material or vice versa. In addition, the package body and/or the lid may comprise two or more different materials, for example, paper based material and plastic material.

The abrasive product roll package may further comprise positioning openings at both ends of the package, wherein the ends are end sides of the package and the end sides are opposite sides of the package. The openings may be arranged in the center area of the end sides of the package. The openings at both ends of the package are formed from cut-outs that are composed of two parts, one part in the package body and the other part in the lid. The cut-outs are arranged to the end side of the package body part and the lid part. The positioning openings are arranged positioning the abrasive product roll inside the product roll package. Further to that, the positioning openings are arranged to form a holder, a fixation, for the protruding ends of the core of the abrasive product roll. The protruding ends of the core are so called supporting axel parts. The protruding ends of the core of the product roll are extensions of the roll core extending out of the product roll; the roll core is longer than the width of the product roll. For example, the roll to be packed may be provided with a core that is approximately two centimeter longer than the width of the rolled product strip i.e. the length of the protruding ends of the core may be approximately one centimeter. The length of the protruding ends i.e. extensions of the core may, however, be longer or shorter than the above mentioned 1 centimeter; the length of the extensions of the core may depend on the width of the roll and/or inner dimensions of the package. The roll may be fixed to the package by placing the extensions of the roll core into the positioning openings in the ends of the package so that the roll is fixed essentially on the center line of the package and thereby contact(s) between abrasive product and package may be avoided. The openings which the cut-outs form at the ends of the package make it possible to place and close the package around the roll when it is still on the roller shaft in the rolling machine. However, instead of the protruding core ends of the abrasive product roll it is also possible use some other supporting axel parts. Supporting axel parts may be, for example, separate extension parts that can be arranged on both ends of the roll so that extensions extend out of the product roll. In addition supporting axel parts may be, for example, ends of a bar that is arranged inside the roll. The bar ends extend of the product roll; the bar is longer than the width of the product roll. The size of positioning openings may be such that the core may rotate when arranged to the positioning openings. One way to brake the product is to press the lid down and clamp the axel parts when the product is torn off. The further purpose of the positioning openings in both ends of the package may be to function as bearing housings when the abrasive product is extracted from the package so that the the positioning openings bears core.

The inner dimensions of the package have to be bigger than the diameter and width of the roll to avoid contact between the abrasive product and the inner surface(s) of the surrounding abrasive product roll package. When abrasive product pieces are linked to one another and rolled into a roll they do not move or glide mutually neither by packing nor by extraction. Further, if the roll is fixed inside the package the products will touch the package with the mineral side neither by storage nor by extraction. Possible materials for the package may be, for example, paper based, plastic material, or some other suitable material and the material of the core may be, for example, plastic, paper or some other suitable material. The outer shape, design and/or material of the package may freely be chosen to be suitable for an abrasive product roll arranged to be packed. In addition to the protective properties of the package, it is advantageous if the package is easy to use. For example, extraction of rolled products may be easy, although the end of material of the rolled product is covered and protected from physical contacts and dust. The end of material of the rolled product is in this context the end of the material that is arranged to be used next.

The lid of the package may be functional and it may be adjusted in different positions; fully open, fully closed, partly opened to form an extraction slot and closed with the front tab out for holding the end of the linked product chain and protecting the same end.

The package may further comprise the opportunity to brake the roll, for example, with a finger in the core, when tearing off a piece from the abrasive product. In addition, it may be possible to roll back extensive material into protection under the lid and inside the package by turning the core from outside of the package by hands. Figure 1 shows a perspective view of a closed product roll package 100 according to an example embodiment. The package 100 comprises a package body part 101 and a lid part 102. The package body 101 is arranged to form the actual box part of the package 100. A front wall 104 and an end wall 106 of the package body 101 are shown, as well as, a lid end tab 109 and a back end tab finger 1 12 of the lid part 102. Further, a positioning opening 120 in the end part of package is shown. The package body part 101 may have, for example, a rectangular shape or a cubic shape of a box. The positioning openings are arranged to be formed for the package 100 when lid part 102 of the package 100 is closed.

Figure 2 shows a perspective view of the product roll package 100 shown in fig. 1. A bottom 103, the front wall 104, a back wall 105, end walls 106, cut-outs of the end walls 107 of the package body 101 are shown. A lid front tab 108, the lid end tab 109, and cut-outs of the lid end tab 1 10, two end tab fingers 1 1 1 , 1 12, of the lid 102 are also show. Further an optional material bridge, a hinge, 1 13 between the package body 101 and the lid part 102 is shown. The lid front tab 108 may also be called product extraction tab due to its functionality.

The cut-outs 107, 1 10 define the positioning opening 120 when the package is closed. Positioning openings 120 are arranged to position the core of the product roll (not shown) into the center of the package 100. The roll may be locked inside the package 100 without touching the inner surface of the package 100.

The front tab 108 of the lid 102 may be left outside i.e. open as a dust protection visor for the rest of product which is left out as much as the front tab portion, visor, covers for facilitating the extraction of the next piece of the product. When the front tab 108 of the lid 102 is left outside, open, the lid 102 is not closed completely, but a slit is left for the linked chain of products to be pulled out. As mentioned above, when the core ends of the roll are protruding from the package 101 it is possible to put a finger into the open end of the core and brake the roll when cutting off the product at the perforations or at a desired length of the rolled product. Another way of braking the roll and product is to press the lid 102 down i.e. to close the extraction slot (532 of fig. 5, 632 of fig. 6, and 732 of fig. 7, 932 of fig. 9) of the package 100. The cut-outs 107 in the end walls 106 and the cut-outs 1 10 in the lid end tabs 109 will then clamp around the core and hold the roll when tearing off the product or piece(s) of the product.

In a closed package 100, the two end tab fingers 1 1 1 , 1 12 at both ends may be placed on different sides of the end walls 106 of the package 100, inside and outside. The front tab fingers 1 1 1 may be arranged outside and the back end tab fingers 1 12 may be arranged inside the end walls 106 of the package 100 or vice versa. This may create a torsion in the end tabs 109 and thereby higher friction which may hold the lid 102 in an adjusted position, when the package 100 is closed. There may also be indentations between the cooperating surfaces of the lid 102 and the body 101 to create a desired hold for the lid 102 at different positions between the open and closed states of the lid. In other words, the lid may be adjusted and/or hold in desired positions with help of desired friction arranged by tab fingers 1 1 1 , 1 12 or indentation(s) between package body 101 and lid parts 102.
