Description

TECHNICAL FIELD The present invention relates to a dispenser used for tape that brings adhesive force into contact with the tape and a liquid.

Tapes are already widely used in which one side of the tape is wetted before use and then applied to an object. Such tapes are sold under the names of water tape, gum tape, and the like. Gum tape is manufactured, for example, by applying glue to a base material such as kraft paper and drying the glue. In use, the adhesive side of the duct tape is wetted with a liquid such as water and then attached to the object.

As shown in Patent Document 1 or Patent Document 2 below, a tape dispenser for applying a liquid to the tape described above has been proposed.

The tape dispenser of Patent Document 1 includes a holder that rotatably supports a tape, an applicator made of a plate-shaped felt sponge, a liquid tank that supplies water to the felt sponge, and a guide roller. The tape fed out from the tape roll supported by the holder is sandwiched between the applicator and the guide roller. When the tape is fed out, the moist applicator comes into contact with the adhesive surface of the tape, thereby moistening the adhesive surface of the tape.

The tape dispenser of Patent Document 2 has a similar configuration to the tape dispenser of Patent Document 1. In the tape dispenser of Patent Document 2, two rollers press the tape against a water application piece made of a plate-shaped sponge. When the tape is unrolled, the moistened water coating comes into contact with the adhesive side of the tape, thereby moistening the adhesive side of the tape.

A fixing part 113 is provided at the upper end of the first member 111 and the lower end of the second member 112 to connect and fix the first member 111 and the second member 112 to each other. The fixing part 113 has an engaging pawl and a pawl receiving part. In the example of FIG. 2, the receiving portion is composed of a through hole, but it may also be composed of a recessed hole. The fixing part may also be composed of other fasteners.

As shown in FIG. 2, the first member 111 includes a support portion 114a for supporting the protrusion of the applicator 13, a support portion 114b for supporting the protrusion of the tape support member 12, and a guide portion. A support portion 114c for supporting the 14 shaft portions is provided. The structure of each support part is not particularly limited as long as it has a shape that can support the application part, the tape support member 12, or the guide part 14.

In the tape dispenser 1, the support portion 114a is composed of three protrusions extending along the vertical direction of the first member 111, as shown in FIG. The length of the middle protrusion is smaller than that of the left and right protrusions. The protrusion of the application part 13 is sandwiched between the left and right protrusions, and the protrusion is rotatably supported from below by the central protrusion. The second member 112 is also provided with three protrusions. By pressing the protrusion of the applicator 13 with the three protrusions, the applicator 13 is prevented from falling off.

The support portion 114b includes a concave portion 116 provided in a convex portion 115 protruding from the wall surface of the first member 111. The tape support member 12 is supported by placing the protrusion of the tape support member 12 on the recess 116. The second member 112 is also provided with a protrusion 117, and by pressing the protrusion of the tape support member 12 with the lower end of the protrusion 117, the tape support member 12 is prevented from falling off.

A projection 119 is provided in the recessed hole 118 to prevent the shaft portion of the guide portion 14 from falling off. As described above, the connecting portion 142 is connected to a position offset from the center of the shaft portion 143. A gap is formed between the wall surface of the recessed hole 118 and the connecting portion 142. As shown in FIGS. 6 and 7, the guide section 14 is arranged in a direction in which the guide section 14 approaches the application section 13 with the shaft section 143 fitted in the recessed hole 118 as the center, or in a direction in which the guide section 14 approaches the tape support member. It is designed to swing in a direction approaching 12.

As shown in FIG. 5, the second member 112 has a tape pushing part 120 at a position facing the tape guide part 14. The push portion 120 has a cross-sectional shape that is a combination of a curved surface and a smooth surface. As shown in FIG. 5, the curved surface of the push portion 120 and the curved surface of the guide portion each have a shape having a portion having substantially the same curvature. The push portion 120 is configured integrally with the second member 112, and is configured so that the number of parts does not increase.

As shown in FIG. 1, the second member 112 constituting the base 11 is provided with openings 123 and 124, each of which is a through hole, above the applicator 13 and the tape support member 12. As shown in FIG. 9, the tape roll 81 supported by the support member 12 is exposed from the opening 124 above the tape support member 12. By rotating the tape roll 81 exposed in the opening 124 with fingers, the tape can be fed out or rewound. The remaining amount of tape can also be checked through the opening 124.

As shown in FIGS. 1 and 9, a porous body 132 constituting the application section 13 is exposed from the opening 123 provided above the application section 13. The opening 123 functions as a tape outlet. For example, as shown in FIG. 10, one end of the tape supported by the tape support member 12 can be let out from the opening 123 so that the adhesive side of the tape comes into contact with the application section 13. When bringing the adhesive side of the tape into contact with the porous body 132 of the application section 13, pinch one end of the tape with your fingers and pull down the tape so that it comes into contact with the application section 13. The application area can be evenly moistened.

The application section 13 and the unwound tape are exposed through an opening 123 provided above the application section. Therefore, the work of applying the liquid can be performed while visually checking whether the liquid is evenly applied to the tape. When the liquid inside the tank 131 runs out, it is possible to check the state of the applicator 13 and the state of the tape through the opening 123 and replenish the tank 131 with the liquid.

The tape is exposed through an opening 124 in the tape support member 12. Therefore, the remaining amount of tape can be easily visually confirmed through the opening 124.

A cutter 15 is provided at the edge of the opening 123 along a direction intersecting the extending direction of the tape. The cutter 15 is provided at the edge of the opening 123 of the tape on the supporting member 12 side. When cutting the tape with the knife 15, the tape is lifted in a direction in which the tape is separated from the coating section 13, and the knife 15 and the tape are brought into contact with each other.

When the user pulls the tape to feed the tape, the guide section 14 is positioned in a direction approaching the application section 13, as shown in FIG. When the guide section 14 is in this state, the tape placed on the guide section 14 is close to the application section 13. This makes it easier to bring the tape into contact with the application section 13.

As shown in FIG. 1 and the like, the base portion 11 has a shape in which a curved portion 125 is provided in a portion housing the applicator portion 13. When feeding out the tape, pinch the tip of the tape with your fingers and pull the tape diagonally downward along the curved part 125, thereby drawing out the tape while bringing the application part 13 into contact with the adhesive side of the tape. be able to.

When the user stops pulling the tape or the tape bends in the direction of rewinding the tape, the guide portion 14 is positioned in a direction approaching the tape support member 12, resulting in the state shown in FIG. 6. In the state shown in FIG. 6, the pushing part 120 of the tape and the guiding part 14 are close to each other, and the tape is placed between the pushing part 120 and the guiding part 14, so that the leading end of the tape is difficult to fall off from the guiding part 14. keep it as is. In this state, the tip of the tape is located away from the application section 13, making it difficult for the tape to get wet with liquid. Note that the guide section 14 also has a function of determining the direction in which the tape is fed out.

In the tape dispenser 1 described above, the applicator 13 rotates and contacts the adhesive surface of the tape to moisten the adhesive surface. If the non-rotating, fixed applicator is in constant contact with the adhesive side of the tape, the applicator may feel like it is caught on the tape when unrolling the tape, or the applicator may feel like it is getting caught on the tape, or the operating feel when pulling out the tape may be poor. becomes heavy. Compared to a case where a fixed application unit that does not rotate is in constant contact with the adhesive surface of the tape, the operational feeling when feeding out the tape is improved.

In the above-mentioned tape dispenser 1, the part for applying the liquid and the tank for storing the liquid are configured as one rotating body. Further, a roller for pressing the tape against the application part can also be omitted. In the above tape dispenser, the number of parts is small, so the device is compact, and the mechanism is simplified, so the device is less likely to break down.

In the dispenser 1 described above, the through-holes 137 for supplying liquid to the porous body 132 are composed of fine holes. Further, the tank 131 is hermetically sealed with a lid 135. The amount of liquid supplied to the porous body 132 through the through holes 137 is limited by capillarity. Therefore, for example, even if the dispenser 1 is turned upside down or tilted, water does not easily leak from the tank 131. When the tank 131 is rotated, liquid is more easily supplied to the outside of the tank 131 due to centrifugal force. Therefore, when the porous body is to contain a large amount of liquid, by rotating the tank 131, the porous body can contain a large amount of the liquid. Note that the first member 111 has a shape that can store liquid, but is not used as a liquid reservoir. Further, the packing 134 may be omitted.

In the tape dispenser 1 described above, the base 11 is composed of a plate-shaped case, but it may also be composed of a block-shaped member. Further, in the dispenser 1, most of the tape support member 12, application section 13, and guide section 14 are covered with the base. It may be configured such that most of the portion is exposed from the base. Although the support member of the tape is configured to be rotatably supported with respect to the base, it may be fixed with respect to the base. In this case, the tape roll may be rotatably supported by the tape support member.

The shape of the tape support member is not limited to the configuration of the above embodiment, and may be any shape that can support the tape roll, such as a cylindrical shape, a columnar shape, a rod shape, or a polygonal column shape. The shape of the application part is not limited to the configuration of the above embodiment, and may be, for example, cylindrical with a polygonal cross section, a cylindrical shape with a star-shaped cross section, or the like. The tank constituting the application section may have a single through hole or a plurality of through holes. Examples of the through-hole include a circular through-hole, a rectangular slit hole, a polygonal through-hole, and the like. The guide portion or push portion of the tape may have a shape other than the shape having the above-mentioned curved portion. The tape guide portion may be composed of, for example, a flat plate-like member, or may be composed of a protrusion that guides the tape. The blade is not limited to the above configuration, and may have any configuration and arrangement suitable for cutting the tape.

In the tape dispenser described above, the tape support member 12, application section 13, and guide section 14 were provided with shafts, and the base 11 was provided with a support section that received the shafts. This relationship may be reversed, and the base may be provided with a shaft, and the support member, application portion, or guide portion of the tape may be provided with a support portion that receives the shaft.
