Abstract

A lateral tear tape comprises a continuous tape (1) rolled on a core (2), and provided with lateral lines of weakness or cutting slots (4) to form strips of the required widths. Both ends of the tape (1) are tapered for easy use and the back surface at one end (3) is blank. i.e. without glue, to enable the tape to be torn laterally using the fingers without it becoming dirty.

Description

LATERAL TEAR TYPE TAPES The present invention relates to a lateral tear tape and, more particularly, to an improved tape which can be torn laterally to form regularly sized films or strips of tape. Hitherto, tape has always been manufactured as a continuous roll and, during se it is cut by a knife or a peir of scissors and so on. Owing to this manner of use, the tape must be manually removed and it is therefore dirtied as well as deglued. Moreover, it is difficult to find the ends of prior tapes which ends are often broken when separated, and prior tapes are difficult to cut into uniform sizes for regular use.
It is therefore an object of the present invention to overcome the aforesaid disadvantages and provide a lateral tear type tape which can be conveniently used.
Another object of the invention is to provide a regularized and standardized tape which is manufactured in suitable predetermined lengths and widths.
A further object is to provide a lateral tear tape which can provide several films on strips in standardized sizes.
Yet another object of the invention is to provide a lateral tear tape which is only partly glued for ease of separation and preventing dirtying.
In order that the present invention may be more readily understood, reference will now be made to the accompanying drawings, in which: Figure 1 is a perspective view of a lateral tear tape according to the invention, Figure 2 is an elevational view of the tape, and Figure 3 is a fragmentary sectional view through the tape of figure 1.
Referring now to Figure 1, the tape 1 is rolled around a cylindrical roll core 2. Several lines of weakness such as cutting slots or score lines 4 are laterally disposed on the tape 1. The cutting slots 4 can be provided at any required spacing to form films, strips or tape pieces 11 of the desired width.
The films 11 formed between every pair of adjacent cutting slots 4 and one end thereof are connected together for providing an unitary edge 3. As shown in the drawing an imaginary line is provided for distinguishing between the right and left sides wherein the back surface of the right side is not glued so as to permit easy tearing apart with the fingers. The unglued portion of the tape 1 is located on the unitary edge 3. The back face of the left side is coated with glue, for the function of sti.ck- ing. The width of the tape 1 can be predetermined by any requirement and the cutting slots 4 could also be manufactured in the form of curves or zigzags etc.
Now referring to Figure 2, the tape 1 is rolled on the core 2 by utilizing a technology of coning to form a construction having two unglued ends 3,5 of the film 11. Because of the unglued end 4, one can laterally tear the film conveniently and since the end 4 is devoid of glue, the film can be separated from the tape 1 easily and without dirtying. Accordingly, it can be seen that the present invention has provided many advantages and improvements. For example, it can provide a formal size of films for regular use and, since one end of the tape is without glue, the use of the tape becomes easier and better than ever before whilst the films are capable of avoiding the risk of becoming dirty. It is obvious that the present invention has provided a new and utility product for good working.
Whilst the invention has been explained in relation to a preferred embodiment, it is to be understood that various modifications thereof will become apparent to those skilled in the art upon reading this specification. Therefore, it is to be understood that the invention disclosed herein is intended to cover such modifications as fall within the scope of the appended claims.

Claims (3)

1. A lateral tear tape in which the tape is wound in a roll and a multiplicity of cutting slots, score lines or other lines of weakness are formed laterally of the tape and in which the tape is partially glued.
2. A lateral tear tape as claimed in claim 1, in which the lines of weakness are formed substantially parallel to the longitudinal axis of the core.
3. A lateral tear tape substantially as hereinbefore described with reference to the accompanying drawings.
