METHOD FOR FIXING TAIL END OF TOILET PAPER ROLL AND TOILET PAPER ROLL THEREFROM

Abstract

A method for fixing a tail end of a toilet paper roll and the toilet paper roll therefrom. The end of the toilet paper roll is not adhered with glue, but the circumference of the toilet paper roll is wrapped by a paper sheet except the toilet paper roll. The head and the tail ends of the paper sheet are not adhered with glue, but joined together in a mechanical combination way, so that the tail end of the toilet paper roll is hooped onto the paper roll by the paper sheet. In this way, there is no need to apply a pressure or any other treatments between the tail end and the external layer of the paper roll when fixing the tail end of the paper roll, the damage of the external layer of the paper roll is avoided, and the quality of the finished paper roll is improved.

3. The method of claim 1, wherein at least one end of the head and the tail ends of the paper sheet extends from the overlapping portions to form a lateral wing.

4. A paper roll, comprising a tail end of the paper roll hooped onto the paper roll by a paper sheet made of material different from that of the paper roll, without bonded with glue, the paper sheet having a head and a tail ends joined together by a mechanically joining mechanism, instead of bonded with glue.

5. The paper roll of claim 4, wherein the mechanically joining mechanism includes any one of: a mechanism in which the overlapping portions between the head and the tail ends of the paper sheet are laminated to form a whole; and a mechanism in which the overlapping portions between the head and the tail ends of the paper sheet are pressed to form convex-concave patterns respectively, and the head and the tail ends of the paper sheet are fitted together through the convex-concave patterns.

6. The paper roll of claim 4, wherein at least one end of the head and the tail ends of the paper sheet extends from the overlapping portions to form a lateral wing.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] FIG. 1 is a structural schematic diagram illustrating a cross section of a paper roll according to a first embodiment of the present disclosure.

[0014] FIG. 2 is a structural schematic diagram illustrating a cross section of a paper roll according to a second embodiment of the present disclosure.

[0015] FIGS. 3-9 respectively show various embodiments in which both head and tail ends of a paper sheet wrapping a paper roll are joined together by way of mechanical joining.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0016] Refer to FIG. 1. It shows a paper roll 1 and a paper sheet 2 wrapping a circumference surface of the paper roll 1. In order to clearly distinguish the paper roll 1 and the paper sheet 2, it is intended to leave a large gap between the paper roll 1 and the paper sheet 2 in FIG. 1. And, in order to clearly show the tail end 1a of the paper roll 1, it is intended to draw the tail end 1a of the paper roll to have a tilted shape in FIG. 1. In fact, there is no gap between the paper roll 1 and the paper sheet 2, and the tail end 1a of the paper roll is hooped onto the paper roll 1 by the paper sheet 2.

[0017] Both head and tail ends of the paper sheet 2 are tilted radially outwardly, to from overlapping portions 2a. In the overlapping portion 2a, both the head and the tail ends of the paper sheet 2 are joined together in a mechanically joining mechanism, instead of bonded with glue. In this embodiment, the mechanically joining mechanism is formed by applying sufficient laminating force on the overlapping portions 2a, to bond the paper fibers together, so that the both head and tail ends of the paper sheet 2 are joined together. The whole overlapping portions 2a may be joined together, and alternatively parts of the overlapping portions 2a may be joined together, for example, laminating may be performed on the overlapping portions 2a at regular intervals along the axial direction of the paper roll (i.e., a direction perpendicular to the figure), so that there is no need to join the whole overlapping portions together.

[0018] FIG. 2 shows another embodiment, which is different from FIG. 1 in that the tail end 1a of the paper roll 1 and the paper sheet 2 are joined together by a mechanically joining mechanism. Other structural features of this embodiment are the same as those in FIG. 1. The mechanically joining mechanism of the tail end 1a of the paper roll 1 and the paper sheet 2 is the same as the mechanically joining mechanism of the head and tail ends of the paper sheet 2.

[0019] FIGS. 3-9 show some different embodiments in which the head and tail ends of the paper sheet 2 are joined together by way of mechanical joining. These structural schematic diagrams may be equivalent to partial enlarged view of the overlapping portions 2a of the head and tail ends of the paper sheet in FIG. 1. The following description will illustrate the different embodiments by reference to FIGS. 3-9 respectively.

[0020] In FIG. 3, the overlapping portions of the head and tail ends of the paper sheet 2 are pressed with concavo-convex patterns 3, and the head and tail ends of the paper sheet 2 are fitted together through the concavo-convex patterns.

[0021] FIG. 4 may be seen as a variation of FIG. 3. The concavo-convex patterns in FIG. 4 are bumps each of which is provided with a through-hole 4 formed by puncture with a needle or the like.

[0022] In FIG. 5, one end of the head and tail ends of the paper sheet 2, i.e., the left end in the figure is bent and wraps the other end to form a wrapping mechanism. In order to clearly show how the end of the paper sheet is bent, it is intended to leave a visible gap at the wrapping portion in FIG. 5. In fact, the head and tail ends of the paper sheet are joined together closely, without gap therebetween. The embodiments shown in FIGS. 3 and 4 may also apply the wrapping mechanism shown in FIG. 5.

[0023] In FIG. 6, both the head and tail ends of paper sheet 2 extend from the overlapping portions to form lateral wings 2b, 2c, respectively. As the advantage of such structure, it is convenient for the user to separate the joined head and tail ends of the paper sheet 2 by drawing the lateral wings 2b, 2c. Further, on the basis of FIG. 6, in FIG. 7, each of the lateral wings 2b, 2c is folded to increase the thickness of the lateral wing and enhance the strength.

[0024] In FIG. 8, one end of the head and tail ends of paper sheet 2, i.e., the left end in the figure extends from the overlapping portions to form a single lateral wing 2b. Further, on the basis of FIG. 8, in FIG. 9, the lateral wing 2b is folded to increase the thickness of the lateral wing and to enhance the strength.

[0025] The embodiments shown in FIGS. 3 and 4 may also apply the lateral wing mechanisms shown in FIGS. 6-9.
