Problems solved by technology

However, when the thickness of the non-woven fabric is increased, the softness is destroyed, and the discomfort when sticking the tape to the skin is increased
[0012] Additionally, if Figure 15 (a) As shown in (b), when the length of the uncut portion Y is made longer than the length of the slit X, the tensile strength of the tape can be increased, but in this case, since the function as the slit X is reduced, the In the state where the tape T is pulled, when the tape is cut directly, it needs to be pulled with a large force to cut it. In addition, if the tape is pulled and cut forcibly, the appearance of the cut, especially the uncut part Y, will be damaged.

Embodiment Construction

[0061] Embodiments of the present invention will be described below with reference to the drawings.

[0062] figure 1 It is a perspective view which shows the reel R of 1st Embodiment of this invention. This roll tape R is used as a medical tape, and a long tape 1 is wound up in multiple layers around a cylindrical roll core 2 . The medical tape is used in the medical field to fix bandages or gauze, etc., and can be directly attached to the patient's skin, etc.

[0063] The tape main body 1c of the adhesive tape 1 is formed of an extremely thin nonwoven fabric using rayon or the like, and has high air permeability, flexibility, and moisture permeability. An adhesive agent 1a for affixing the tape 1 to the patient's skin or the like is laminated on the back surface of the tape 1 .

[0064] The adhesive tape 1 has a plurality of cutting portions 11 for selectively cutting the adhesive tape 1 along the width direction. The cutting portions 11 are formed at regular intervals ...

Abstract

In a middle region (A) of adhesive tape (1) is provided a long cut line (21) extending along a virtual cut line (D). This long cut line (21) is made longer in length than a second adjacent cut line (22) provided in an adjacent region (B) and an outside cut line (23) provided in an outside region (C). The adjacent region (B) and outside region (C) of the adhesive tape (1) are provided with a tensile strength that can withstand the tensile stress that arises when the adhesive tape (1) is unreeled.

Description

technical field [0001] The present invention relates to a reel for winding long tapes. Background technique [0002] Conventionally, medical tapes, band-aids, etc. are often used at medical sites, and an adhesive is laminated on the tape with the main body. As roll tape, the tape is usually wound on a cylindrical roll core. The adhesive tape is required to have air permeability, softness and moisture permeability because it is directly pasted on the skin of the human body. Therefore, a thin nonwoven fabric formed of rayon or the like forms the belt main body (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-116695 [0004] The adhesive tape whose main body is made of a thin non-woven fabric has good air permeability, flexibility, moisture permeability, etc., and has a function suitable for the adhesive tape that causes little discomfort when sticking on the skin. However, since nonwoven fabrics in particular have st...
