Description

Technical Field

[0001] The present invention relates to a tape dispenser.

Background Art

[0002] In the packaging of cardboard boxes and the like, adhesive tapes having an adhesive layer on one side of kraft paper, cloth, vinyl, etc. have been widely used. In Japan, since it is difficult to recycle adhesive tapes, when disposing of cardboard boxes, it is required to peel off the adhesive tapes for the purpose of recycling the cardboard boxes.

[0003] On the other hand, the use of tapes in which dried aqueous paste is processed on one side of a base material such as kraft paper is spreading. When using such a tape, adhesion is caused by applying water to the paste surface, and it is adhered to an adherent object such as a cardboard box.

[0004] For such tapes, various tape dispensers have been proposed for the purpose of applying water to the tapes to give the tapes adhesiveness to adherent objects (Patent Documents 1 to 4).

It is characterized by the following:

[0009] Furthermore, it is preferable that when the flap is pushed down, the flap comes into contact with the main body and its rotation is restricted, thereby ensuring that the force with which the tape pressing portion presses the tape remains constant.

[0011] Further, it is preferable that the coating substrate pressing portion abuts against the coating substrate to make the distance between the tape pressing portion and the coating substrate constant.

[0012] Also, the interval between the pair of coating substrate pressing portions is preferably wider than the width of the coating member and narrower than the width of the coating substrate.

[Modes for carrying out the invention]

[0017] The tape dispenser according to this embodiment will be described with reference to the figures. As shown in Figures 1 and 2, the tape dispenser 1 comprises a main body 10, an applicator 20, and a flap 30. The tape dispenser 1 is configured with the applicator 20 and flap 30 attached to the main body 10.

[0018] Tape dispenser 1 applies a liquid to the side of a tape wound around a core material, where a dry water-based adhesive has been applied to one side of a base material such as kraft paper, thereby creating adhesion. The water-based adhesive is applied to the inner circumference of the wound tape, and hereafter, the inner circumference of the tape with the water-based adhesive applied will also be referred to as the adhesive side. The liquid that creates adhesion is often water, but is not limited to water.

[0019] The main body 10 includes a tape cover 11, a side plate 12, a tape support section 13, a support shaft 14, a tank 15, and a coating body installation section 16.

[0020] The tape cover 11 protrudes from the side plate 12 and has a cylindrical shape with a portion cut out. The tape cover 11 protects the attached tape. The cut-out portion of the tape cover 11 serves as a passage for the tape to pass through during use. The bottom of the tape cover 11, along with the bottom of the tank 15, contributes to the self-supporting of the tape dispenser 1. The top of the tape cover 11 restricts the movement of the flap 30, which will be described later.

[0021] The tape support section 13 rotatably supports the wound tape. The tape support section 13 has a cylindrical shape corresponding to the shape of the tape core and protrudes from the side plate 12 of the main body 10. A part of the tape support section 13 has two notches formed therein, which gives it a fall prevention section 13a that can move radially. The tip of the fall prevention section 13a has a claw that widens radially. When attaching the tape, inserting the tape core into the tape support section 13 causes the fall prevention section 13a to deform inward, allowing it to be accepted into the tape support section 13, and inserting the tape core all the way in prevents the attached tape from falling off with the claw at the tip. There is no limit to the number of fall prevention sections 13a; in this case, a pair of fall prevention sections 13a are formed diagonally opposite each other.

[0022] Furthermore, the side plate 12 has an opening 12b formed in a part of the section sandwiched between the tape cover 11 and the tape support part 13. After the tape is used up, the core of the tape can be pushed out and removed through the opening 12b with a finger or the like. The opening 12b is large enough for a finger or the like to be inserted and is positioned in a place where the core of the tape can be pushed out.

[0023] Tank 15 stores the liquid to be applied to the adhesive surface of the tape. The top of Tank 15 is partitioned by the coating material mounting plate 16a, forming a recess, which functions as the coating material installation section 16. The coating material installation section 16 consists of the coating material mounting plate 16a, ventilation holes 16b, fixing grooves c, and an opening 16d.

[0024] The coating material mounting plate 16a is rectangular in shape, and three sides are fixed to the inner wall of the tank 15. A rectangular opening 16d is formed between the one side of the coating material mounting plate 16a that is not fixed and the inner wall of the tank 15. The width of the opening 16d, that is, the distance between the side of the coating material mounting plate 16a that is not fixed to the wall surface of the tank 15 and the inner wall surface of the tank 15, should be set to a degree that allows the liquid absorption portion 22b of the coating member 22 to pass through, for example, about 1 to 5 mm.

[0025] Multiple ventilation holes 16b are formed in the coating material mounting plate 16a. The ventilation holes 16b suppress pressure fluctuations inside the tank 15 caused by the absorption of liquid inside the tank 15 into the coating member 22, thereby preventing the absorption of liquid into the coating member 22 from being hindered.

[0026] Furthermore, fixing grooves 16c are formed opposite each other on both wall surfaces of the coating material installation section 16. As will be described later, the fixing grooves 16c hold the coating material 20 in a fixed position on the coating material installation section 16.

[0027] The applicator 20 is placed on the applicator mounting plate 16a. The applicator 20 absorbs the liquid in the tank 15 and applies the absorbed liquid to the adhesive surface of the tape. The applicator 20 comprises an applicator base 21 and an applicator member 22. The applicator member 22 comprises an applicator part 22a and a liquid absorption part 22b.

[0028] As shown in Figure 3, the coating substrate 21 is a base to which a strip-shaped coating portion 22a is wound and attached. Also, as shown in Figure 2, fixing portions 21a protrude from both sides of the coating substrate 21. The coating body 20 is installed in the coating body installation portion 16 by inserting the fixing portions 21a into fixing grooves 16c provided in the coating body installation portion 16. This ensures that the position of the coating body 20 and the coating body installation portion 16 remains constant.

[0029] The coating member 22 comprises a strip-shaped coating portion 22a, which is wrapped around the coating substrate 21, and a strip-shaped liquid absorption portion 22b, which is fixed to the coating portion 22a and inserted into the tank 15. The coating portion 22a directly contacts the adhesive surface of the tape and performs the function of applying liquid to the adhesive surface. The liquid absorption portion 22b absorbs the liquid in the tank 15 and transfers the liquid to the coating portion 22a. Here, the coating portion 22a and the liquid absorption portion 22b are shown as separate components, with the liquid absorption portion 22b being joined to the coating portion 22a, but the coating portion 22a and the liquid absorption portion 22b may also be formed from a single component.

[0030] The material of the coating member 22 is not limited as long as it can adequately perform the function of absorbing the liquid in the tank 15 and applying the absorbed liquid to the adhesive surface of the tape. For example, a water-absorbing sponge such as polyvinyl alcohol (PVA) can be used as the material of the coating member 22. PVA sponge has a three-dimensional mesh structure in which individual pores are completely continuous, and about 90% of its volume is hollow. PVA sponge has high hydrophilicity and exhibits excellent water absorption and retention due to capillary action caused by its fine pores. Therefore, when a PVA sponge comes into contact with moisture, it quickly absorbs the moisture, takes it inside, and retains it. Furthermore, because PVA sponge has excellent flexibility and elasticity in the water-absorbing state, it can evenly contact the adhesive surface of the tape without damaging the adhesive surface of the tape.

[0031] There is no limit to the thickness of the coating member 22, and it is set appropriately based on the width of the opening 16d, the size of the coating base 21, the depth of the coating member installation section 16, and the difference between the protrusion amount of the tape pressing section 34 and the protrusion amount of the coating base pressing section 35, which will be described later. For example, the thickness of the coating member 22 is set to about 1 to 3 mm.

[0032] The width of the coating portion 22a (D1 shown in Figure 3(B)) is set to be shorter than the width of the coating substrate 21 (D2 shown in Figure 3(B)). The width of the coating portion 22a should be set to be slightly wider than the width of the tape used so that the liquid can be applied to the entire width of the tape when applying it to the adhesive surface of the tape. In addition, the distance between the end of the coating substrate 21 and the end of the coating portion 22a (D3 shown in Figure 3(B)) is set to be greater than or equal to the thickness of the coating substrate pressing portion 35, which will be described later.

[0033] The flap 30 functions to press the tape against the applicator 20, allowing the applicator 20 to apply liquid to the adhesive surface of the tape. The flap 30 has a curved top plate 31 from which side plates 32 extend from both sides. Both side plates 32 have coaxially formed support shaft holes 33. The flap 30 is attached to the main body 10 by inserting the support shaft 14 of the main body 10 into the support shaft holes 33. As a result, as shown in Figure 4, the flap 30 is rotatable around the support shaft 14.

[0034] As shown in Figure 5, the flap 30 includes a tape pressing portion 34 and a coating substrate pressing portion 35 that protrude from the back surface toward the coating body 20 when in use.

[0035] The tape pressing section 34, as the pulled-out tape passes through, contacts the outer surface of the tape, pressing the tape against the applicator 20 and performing the function of applying the liquid absorbed by the applicator 22a to the adhesive surface of the tape. The contact surface of the tape pressing section 34 with the tape is formed smoothly so that the tape can be pressed uniformly against the applicator 22a.

[0036] The protruding height of the tape pressing portion 34 (H1 shown in Figure 6) is appropriately set according to the curved shape of the flap 30. For example, when the flap 30 is closed, the rear of the top plate 31 of the flap 30 is separated from the top of the tape cover 11, and when in use, when the flap 30 is pressed in the closing direction, the tape pressing portion 34 is set to sufficiently press the tape against the applicator 20, while the rear of the top plate 31 of the flap 30 comes into contact with the top of the tape cover 11.

[0037] The coating substrate pressing portion 35 is a plate-shaped member that protrudes from the underside of the top plate 31, spaced apart in the width direction of the tape and straddling the tape pressing portion 34. It functions to contact the coating substrate 21 and press the coating substrate 21 toward the tank 15. It also functions as a guide to suppress misalignment in the width direction as the tape passes between the coating body 20 and the tape pressing portion 34.

[0038] The coating substrate pressing sections 35 are arranged in pairs. The distance between the pair of coating substrate pressing sections 35 (D4 shown in Figure 6) is set to be the same as or slightly longer than the width of the tape. For example, a widely used tape width is 50 mm, and in the case of a 50 mm wide tape, the distance between the pair of coating substrate pressing sections 35 is preferably 50 to 52 mm, and more preferably 50.5 to 51 mm. If the distance between the pair of coating substrate pressing sections 35 is too narrow, it becomes difficult for the tape TA to pass through, while if the distance is too wide, the tape TA is more likely to shift in the width direction, which may result in uneven application of the liquid to the adhesive surface. In this case, the coating substrate pressing sections 35 are formed integrally with the tape pressing section 34, but they may also be arranged at a distance from the tape pressing section 34.

[0039] The height of the coating substrate pressing portion 35 (H2 shown in Figure 6) is set according to the thickness of the coating body 20, and is installed so as to allow sufficient liquid to be applied to the back surface of the tape and to provide sufficient resistance for smooth tape removal. If the coating portion 22a is a PVA sponge, it swells when it absorbs liquid and its thickness increases, so if the height of the coating substrate pressing portion 35 is too low, it becomes difficult for the coating substrate pressing portion 35 to contact the coating substrate 21 during use. On the other hand, if the height of the coating substrate pressing portion 35 is too high, the tape pressing portion 34 will not be able to sufficiently press the tape against the coating portion 22a. For this reason, the height of the coating substrate pressing portion 35 is preferably about 0.8 to 1.2 times the thickness of the coating portion 22a, and more preferably 0.9 to 1.1 times.

[0040] Furthermore, a cutter 36 is formed at the tip of the flap 30. The cutter 36 is a blade with a typical serrated shape and serves the function of cutting the pulled-out tape.

[0041] Furthermore, it is preferable that the main body 10, the coating substrate 21, and the flap 30 are all made of resin. This would result in a lightweight and easy-to-operate device, and allow the tape dispenser 1 to be provided at a low cost.

[0042] Next, we will explain how to use the tape dispenser 1. First, insert the core TA1, around which the tape TA is wound, into the tape support section 13 of the main body 10. Insert the core TA1 until it passes the claw of the anti-drop section 13a to secure the tape TA.

[0043] Then, as shown in Figure 7, with the flap 30 open, the tape TA is pulled out through the opening of the tape cover 11, the tape TA is passed over the coating body 20, and then passed between the main body 10 and the flap 30, and then the flap 30 is closed as shown in Figure 8.

[0044] As shown in Figure 9, hold down the flap 30 from above with your hand, and pull out the tape TA in this position.

[0045] As shown in Figure 10, when the flap 30 is pressed by hand, the tape pressing part 34 presses the tape TA against the coating body 20, and the adhesive surface of the tape TA comes into contact with the coating part 22a. Since the liquid in the tank 15 has sufficiently permeated the coating part 22a via the liquid absorption part 22b, when the adhesive surface of the tape TA comes into contact with the coating part 22a, the liquid is applied from the coating part 22a to the adhesive surface of the tape TA, and the tape TA is pulled out.

[0046] Furthermore, when the tape TA is pulled out while the flap 30 is held down, the tape TA passes between the coating substrate pressing portions 35 on both sides. Since the coating substrate pressing portions 35 also function as guides for the tape TA, the tape TA does not shift in the width direction, and the adhesive surface of the tape TA contacts the coating portion 22a over its entire width, so that the liquid is applied evenly and uniformly to the adhesive surface, and adhesion is given to the tape TA.

[0047] Furthermore, when the flap 30 is pressed down, the rear of the top plate 31 of the flap 30 comes into contact with the upper part of the tape cover 11 of the main body 10, restricting the movement of the flap 30. In addition, the coating substrate pressing part 35 comes into contact with the coating substrate 21, restricting the pressing of the tape TA by the tape pressing part 34. As a result, the pressing force of the tape TA against the coating body 20 by the tape pressing part 34 is kept constant. In other words, the tape pressing part 34 does not press the tape TA against the coating body 20 with excessive force. Therefore, the adhesive surface of the tape TA is evenly coated over its entire surface, and no excessive force is required to pull out the tape TA, allowing the tape TA to be pulled out smoothly.

[0048] As shown in Figure 11, after pulling out the required length of tape TA, the tape TA can be cut using the cutter 36 and then attached to the object to be adhered to. When cutting the tape TA, holding down the flap 30 prevents unnecessary tape TA from being pulled out, making it easy to cut the tape TA.

[0049] Thus, the tape dispenser 1 according to this embodiment offers excellent ease of use.

[0050] This invention allows for various embodiments and modifications without departing from the broad spirit and scope of the invention. Furthermore, the embodiments described above are for illustrative purposes only and do not limit the scope of the invention. In other words, the scope of the invention is indicated not by the embodiments, but by the claims. Various modifications made within the scope of the claims and the equivalent scope of the meaning of the invention are considered to be within the scope of the invention. [Explanation of Symbols]
