Description

Line Marker

[0001] The present invention relates to a line marker, and particularly to a line marker that can be erased with an eraser.

[0002] [Explanation of Prior Art] Since conventional line markers use ink, once drawn over text, they cannot be erased.

[0003] Also, instead of ink, there are some that use a transparent fluorescent tape and stick it over text like correction tape and then can peel off the tape, but they cannot be partially erased with an eraser.

[0004] [Related Technologies] As related prior arts, there are Japanese Patent Application Laid-Open No. 2003-211597 "Recording Material for Writing Instruments" (Patent Document 1), Utility Model Registration No. 3126930 "Tape-Type Line Marker That Can Be Attached and Removed" (Patent Document 2), and Japanese Utility Model Publication No. 07-52133 "Plastic Tape-Type Marker" (Patent Document 3).

[0005] Patent Document 1 describes a special writing property imparting layer provided, and although the characters written with a writing instrument on the imparting layer can be erased with an eraser, the imparting layer itself cannot be erased. Patent Document 2 describes a tape-type line marker with a configuration that can generate and delete lines by sticking and peeling. Patent Document 3 describes a configuration in which a slightly adhesive agent is applied to one side of a plastic tape and the tape is peeled off when erasing.

[0007] However, conventional ink-based line markers have the problem of being inconvenient because the marker drawn over text etc. cannot be easily erased with an eraser. Also, conventional tape-type line markers have the problem of being inconvenient because although the entire marker can be peeled off, only a part cannot be erased.

[0008] Furthermore, Patent Documents 1 to 3 do not describe any tape-type highlighters that can be easily erased with an eraser.

[0009] This invention has been made in view of the above circumstances, and aims to provide a tape-type line marker that can be easily erased with an eraser.

[0010] The present invention, which solves the problems of the above-mentioned conventional example, is a tape-type line marker comprising: a marker tape having a base tape attached on top of a translucent, adhesive-backed colored tape; a tape reel with the marker tape wound around a core; an outlet from which the marker tape is discharged; a blade section that, when the marker tape is pressed against paper and discharged from the outlet, peels the colored tape from the base tape, adheres the back side to the paper, and cuts the colored tape; and a winding reel that winds up the base tape from which the colored tape has been peeled off. The colored tape that is attached to the paper can be erased with an eraser.

[0011] Furthermore, in the line marker described above, the present invention provides a colored tape in which a transparent adhesive layer is formed beneath a translucent colored film, and a base tape is attached on top of the colored film to form the marker tape.

[0012] Furthermore, the present invention provides a line marker in which the case comprises two unit sections, each of which is equipped with a marker tape, a tape reel, a blade section, and a winding reel, and the colored film of the marker tape in the two unit sections is colored in different colors.

[0013] Furthermore, in the line marker described above, the case is stick-shaped, the blade portion of one unit is provided protruding from an outlet formed at one end of the case, and the blade portion of the other unit is provided protruding from an outlet formed at the other end of the case.

[0014] Furthermore, in the line marker described above, the thickness of the colored tape is set to 8 μm or more and 20 μm or less.

[0015] According to the present invention, a tape-type line marker has a case comprising: a marker tape in which a base tape is attached on top of a translucent, adhesive-backed colored tape; a tape reel in which the marker tape is wound around a core; an outlet from which the marker tape is discharged; a blade section that, when the marker tape is pressed against paper and discharged from the outlet, peels the colored tape from the base tape, adheres the back side to the paper, and cuts the colored tape; and a take-up reel that winds up the base tape from which the colored tape has been peeled off. Since the colored tape attached to the paper can be erased with an eraser, it is possible to easily erase a mark without damaging the paper and re-mark another area, thereby improving convenience.

[0016] Furthermore, according to the present invention, the case is equipped with two unit sections, each comprising a marker tape, a tape reel, a blade section, and a winding reel. The colored film of the marker tape in the two unit sections is colored in different colors, so that two colored lines can be drawn with a single line marker, providing the advantage of being able to use them interchangeably depending on the purpose.

This is a front view of the cap of this line marker. This is an explanatory diagram showing the structure of the marker tape.

[0018] Embodiments of the present invention will be described with reference to the drawings. [Summary of Embodiments] The line marker according to an embodiment of the present invention (this line marker) is a tape-type line marker and has a case comprising a marker tape in which a base tape is attached on top of a translucent colored tape with adhesive on the back, a tape reel in which the marker tape is wound around a core, an outlet from which the marker tape is discharged, a blade section that, when the marker tape is pressed against paper and discharged from the outlet, peels the colored tape from the base tape, attaches its back side to the paper and cuts the colored tape, and a winding reel that winds up the base tape from which the colored tape has been peeled off. The attached colored tape can be easily erased with an eraser, and it is possible to erase a marked area and re-mark another area, thereby improving convenience.

[0019] [Outline of this line marker: Figures 1-4] The outline configuration of this line marker will be explained with reference to Figures 1-4. Figure 1 is a right side view of this line marker, Figure 2 is a left side view of this line marker, Figure 3 is a bottom view of this line marker, Figure 4 is a top view of this line marker, and Figure 5 is a front view of this line marker. The rear view is the same as the front view and is therefore omitted. As shown in Figures 1-5, this line marker comprises a main body 1 and caps 2a and 2b.

[0020] The main body 1 consists of two sets of unit sections (marker tape units) for drawing tape-type marker lines, housed in a transparent plastic case. As will be described later, each unit section houses marker tapes 30 (30a, 30b), and has a mechanism for attaching the colored tape to the surface of a notebook or book (hereinafter referred to as "the surface") to draw marker lines, and for retrieving the base tapes 33 (33a, 33b). Basically, it has the same configuration as the mechanism of correction tape. In this line marker, as shown in Figure 4, it is equipped with unit section A and unit section B.

[0021] Unit A and Unit B have the same basic configuration, but the marker tapes 30a and 30b are different colors. This allows two different colored marker lines to be drawn with a single stick. Discharge ports (openings) 5a and 5b are provided at both ends (front and back) of the stick-shaped main body 1, so that the marker tapes 30a and 30b are discharged from different ends.

[0022] Furthermore, a blade portion 6a is provided so as to protrude from the discharge port 5a, and a blade portion 6b is provided so as to protrude from the discharge port 5b. Caps 2a and 2b are detachably provided at both ends of the main body 1 from which the marker tapes 30a and 30b are discharged.

[0023] [Marker Tape Structure: Figure 6] Before specifically describing the structure of the unit part of this line marker, the structure of the marker tape 30 will be explained using Figure 6. Figure 6 is an explanatory diagram showing the structure of the marker tape. As shown in Figure 6, the marker tape 30 has a three-layer structure, with an adhesive layer 31, a colored film 32, and a base tape 33 stacked in order from bottom to top. The colored film 32 is a film made of a transparent material that is colored to be light-transmitting, and is colored in a color that makes the letters and other text underneath the colored tape clearly visible when it is attached to a paper surface or the like. The color of the colored film 32 may be fluorescent or non-fluorescent.

[0024] The adhesive layer 31 is a layer containing an adhesive with weak adhesive strength. In Figure 6, the adhesive layer 31 is shown protruding from the colored film 32 to clearly show that the marker tape has three layers, but it may also be formed by coating it on the back surface of the colored film 32, for example.

[0025] In this specification, the portion consisting of the adhesive layer 31 and the colored film 32 is referred to as the colored tape. When pressed onto a paper surface and discharged, the adhesive layer 31 beneath the colored film 32 adheres to the paper surface, and the colored tape forms a marker line. To ensure that the text and other elements beneath the colored tape are clearly visible when attached to a paper surface, the thickness of the colored film 32 and the adhesive layer 31 is made thinner than that of correction tape.

[0026] The base tape 33 is a support layer that holds the colored tape, which consists of an adhesive layer 31 and a colored film 32. The base tape 33 is unwound from the tape reel 4 overlapping the colored tape, the colored tape is peeled off via the blade portion 6, and only the base tape 33 is wound onto the take-up reel 7. The film thickness of the base tape 33 is 12 μm to 40 μm (0.012 mm to 0.040 mm).

[0027] In particular, the colored tape of the present invention can be easily erased by rubbing it with an eraser after it has been applied to the paper surface, as the tape is scraped off the paper surface and adheres to the eraser. The colored tape, which combines the colored film 32 and the adhesive layer 31, is formed to be thinner than the type of tape that allows you to peel off the marker line by hand, and the film thickness of the colored tape is 8 μm to 20 μm, with 10 μm to 17 μm being preferable. The thickness of the colored tape varies depending on the color of the colored film 32.

[0028] Furthermore, the adhesive strength of the adhesive layer 31 is adjusted to be stronger than that of sticky notes but weaker than that of correction tape. The adhesives used in correction tape are generally acrylic or rubber-based, which adhere firmly to the surface and have the properties to withstand long-term use. However, the adhesive in this adhesive layer 31 has been adjusted in terms of material and composition to be easy to peel off and flexible. Moreover, if the amount of adhesive is too little, the colored tape will not adhere well to the paper, and if there is too much, it will be difficult to erase with an eraser, so the amount has also been adjusted to an appropriate level.

[0029] Furthermore, while the main component of the correction film in typical correction tapes is a white pigment (titanium dioxide), the main component of the colored film 32 of this line marker is, for example, a fluorescent powder pigment, which allows for the formation of a tape with a bright color.

[0030] [Unit Configuration: Figures 1-4] Next, the configuration of the unit will be explained using Figures 1-4. As shown in Figures 1-4, unit A basically consists of a tape reel 4a, a marker tape 30a, a blade section 6a, and a take-up reel 7a. Similarly, unit B basically consists of a tape reel 4b, a marker tape 30b, a blade section 6b, and a take-up reel 7b. As mentioned above, unit A and unit B have the same configuration except for the color of the marker tape 30, so in parts where it is not necessary to distinguish between unit A and unit B, the lowercase English subscript will be omitted in the explanation.

[0031] The tape reels 4 (4a, 4b) are reels on which the marker tape 30 is wound around a core before use. As described above, the marker tape 30 (30a, 30b) is a three-layer tape.

[0032] The blade section 6 (6a, 6b) peels off the colored tape (colored film 32 and adhesive layer 31) portion from the marker tape 30 when the back side of the marker tape 30 is pressed against the paper surface and is discharged, and then cuts the colored tape. The take-up reel 7 (7a, 7b) is a reel that winds up the base tape 33 after the colored tape has been peeled off by the blade section 6.

[0033] As shown in Figure 2, the tape reel 4a and the take-up reel 7a are connected by a connecting belt 8a and rotate in conjunction with each other. Similarly, the tape reel 4b and the take-up reel 7b are connected by a connecting belt 8b and rotate in conjunction with each other. This ensures that the unwinding of the marker tape 30 and the winding and retrieval of the base tape 33 proceed at the same pace, preventing the tape from becoming slack or pulled.

[0034] As shown in Figure 1, in unit A, the marker tape 30a is pulled out from the tape reel 4a and discharged from the discharge port 5a, pressed against the paper surface by the blade 6a to peel off and cut the colored tape, and the base tape 33a is wound onto the take-up reel 7a. The same applies to unit B, but the marker tape 30b and base tape 33b are not shown in Figures 1 to 4.

[0035] [Case Configuration: Figures 1-4] The case forms the outer casing of the main body 1 and is made of a rigid, transparent plastic that is resistant to deformation. It serves as a container for housing the unit. The case is hollow and stick-shaped, with outlets 5 (5a, 5b) at both ends. The outlets 5 are openings for discharging the marker tape 30 to the outside of the case 1. The cross-sectional shape of the case in the lateral direction is roughly trapezoidal, making it easy to hold like a pen.

[0036] Furthermore, as shown in Figure 4, multiple anti-slip sections 11, which are convex straight lines, are formed on the upper surfaces of unit sections A and B, perpendicular to the longitudinal direction of the case. The anti-slip sections 11 prevent the fingers from slipping towards the front of the case even when force is applied when drawing colored lines.

[0037] [Construction of Cap 2: Figure 5] Next, the structure of cap 2 will be explained using Figure 5. Figure 5 is a front view of the cap. As shown in Figure 5, cap 2 is a lid that covers the tip of case 1 and is made of a roughly trapezoidal, translucent, soft plastic or the like. Cap 2 protects the blade portion 6 that protrudes from the tip of case and prevents damage.

[0038] [Effects of the Embodiment] This line marker is a tape-type line marker and has a case comprising: a marker tape 30 in which a base tape 33 is attached on top of a translucent colored tape with adhesive on the back; a tape reel 4 in which the marker tape 30 is wound around a core; an outlet 5 from which the marker tape 4 is discharged; a blade section 6 that, when the marker tape 30 is pressed against paper and discharged from the outlet 5, peels the colored tape from the base tape 33, attaches its back side, and cuts the colored tape; and a take-up reel 7 that winds up the base tape 33 from which the colored tape has been peeled off. The attached colored tape can be easily erased with an eraser, and for example, by erasing a marked and memorized part in a reference book and re-marking another part, the same reference book can be used repeatedly to memorize different things, thus improving convenience.

[0039] Furthermore, this line marker has a three-layer structure consisting of an adhesive layer 31, a colored film 32, and a base tape 33. The combined thickness of the colored tape, including the adhesive layer 31 and the colored film 32, is made thin to about 8 μm to 20 μm, which allows the marked line to be easily erased with an eraser without damaging the paper.

[0040] This invention is suitable for tape-type highlighters that can be easily erased with an eraser.
