DETAILED DESCRIPTION

[0030] Referring to FIGS. 1 to 2, a coreless roller for toilet paper comprising: a hollow cylinder body 100 and a side strip 200. The groove 101 is provided on the outer side wall of the hollow cylinder body 100, and this groove 101 is filled by the side strip 200.

[0031] The outer surface of the hollow cylinder body 100 and the outer side of the side strip 200 are smooth. The cylinder body and the side strip 200 to be easily removed from the rolled toilet paper. The roller can be removed from either side when the rolled paper is fully sleeved on the roller. The length of the cylinder body is comparable to the rolled paper generally sold on the market. The outer diameter may be 43 mm and the length may be 100-130 mm (preferably 110 mm). The rolled paper exceeding a width of 120 mm will be difficult to be used on a conventional toilet paper tube or toilet paper holder. It is not recommended that consumers purchase coreless rolled paper with a width of more than 110 mm.

[0032] A groove 101 runs along the cylinder body 100 in an axial direction through its outer side wall and a side strip 200 fills the groove 101. The groove 101 and the side strip 200 are substantially complementary in cross-sectional shape and not completely geometrically complementary. The cross-section of the groove 101 is in the shape of trapezoidal features with a wide outer width and a narrow inner width. There is a certain gap between the inner face of the side strip 200 and the bottom of the groove 101 opposite thereto. For example, a gap of 1 mm (about 4 ply thickness will not cause the outer side of the side strip 200 to protrude from the groove 101 of the roller) is able to cooperate with different thicknesses of toilet paper on the market, which can avoid being torn.

[0033] Magnetic attractor 102, 201 is provided on both the inner side of the side strip 200 and the bottom of the groove 101 opposite thereto. The side strip 200 may be allowed to be fixed in the form of snap fasteners in the groove 101 of the cartridge body. The side strip 200 may be made of plastic or iron sheet material.

[0034] If snap fastening is used, toggle-able iron or film sheets are fitted at both ends of the groove 101. When the side strip 200 is pressed against the groove 101, the toggle-able iron or film sheets hold the side strip 200 in place.

[0035] If the magnetic attractors 102, 201 are used for fixing, they are evenly distributed along the axial direction of the cylinder (the number of evenly distributed friction force is appropriate in order that the paper will not be damaged when the side strip 200 are withdrawn), so that the toilet paper is pulled with an even force to avoid being torn along the radial direction of the cylinder when it is rolled up. The main purpose of adopting the magnetic attractors 102, 201 is to be able to pull the smooth outer surface of the rolled toilet paper without destroying the toilet paper. The number and distribution of the magnetic attractors 102, 201 is decided after testing. If the magnetic attractors 102, 201 is too many or too dense, it will lead to strong magnetic force when the roller is pulled out. It is very easy to tear the toilet paper while the magnetic attractors 102, 201 is too little, it leads to insufficient magnetic force. The side strip 200 can not be compacted toilet paper. When the cylinder body is rotated, the paper will come loose and leave the groove 101.

[0036] This solution is preferred to magnetically fix the side strip 200, because after a long time, the iron sheet or film, the rotating bit will be fatigue phenomenon. It is likely to fall out of the cylinder body, but the magnetic attractor does not happen.

[0037] The radial width of the outer edge of the groove 101 is about one finger's width, so it is convenient for the side strip 200 to be took out from the rolled paper along the axial direction;

[0038] The entire hollow cylinder body can be used with a power device to roll toilet paper. It is also capable of being used with a telescoping roller or with a conventional toilet paper holder.

[0039] The cylinder body and side strip 200 material are preferred for plastic, because the roller is in the toilet for a long time in a humid environment. With other materials, such as recycled wood, there is a great chance of mold and bacteria. The use of plastic does not have this disadvantage and the use of plastic manufacturing cost is relatively inexpensive.

[0040] The method of using the roller is as follows: Remove the side strip 200 on the roller, the user will put the end edge of the last frame of the coreless rolling paper into the groove 101 of the cylinder body and then press the side strip 200 on the paper in the groove 101. The beginning end of the paper will be pressed into the groove 101. Rotate the roller until the whole roll of paper is completely set on the roller (it can be drove by manually or by electric tool). When the coreless roll of paper rolled in the roller completely set in the whole roll of paper, the roller of the cylinder body from the left or right with a little force a push, the user can easily top out the cylinder body. Put the roller of paper on the traditional roll of paper tube wrapped can be used, the roller of paper is extracted from the inner (to the outer). It can be placed in the traditional toilet paper tube to use or like ordinary core rolled paper in the toilet paper holder on the toilet paper (when the coreless rolled paper rolled completely in the roller, and then put into the toilet paper holder of the telescopic roller. It can be used directly, and the rolled paper is extracted from the outer to the inner).

[0041] For the production method of the roller, when the magnetic attractor fixing method is used, a cylinder body 100 suitable for the inner and outer diameters is first manufactured, and then cut into specified unit lengths. The axial grooves 101 are planned on the outer side walls of the cut cylinder body 100. The holes are drilled in the bottoms of the grooves 101 and magnetic attractors 102, 201 are placed in the holes, and fixed by utilizing glue; According to the size of the grooves 101, the side strip 200 is made according to the size of the groove 101 and the magnetic attractors 102, 201 corresponding to the holes are fixed with glue in the inner side portion of the side strip 200. The inner side of the side strip 200 and the bottom of the groove 101 opposite thereto are attracted to each other and a magnetizable metal strip can also be affixed to the entire inner side portion of the side strip 200.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes may be made within the scope of knowledge possessed by persons of ordinary skill in the technical field to which it belongs without departing from the purpose of the present invention.
