Description

The present invention relates to an automatic inner sheet attachment roll tape cutter, and more specifically, to a roll tape cutter with an automatic inner sheet attachment type that is configured so that an inner sheet (or label sheet) is automatically attached one by one to the underside of the tape during the taping work of a packaging box, so that when a consumer opens (unboxes) the packaging box, they can pull the inner sheet attached to the tape and easily peel the tape off the packaging box, making it not only easy to open the packaging box but also extremely useful in terms of separating and collecting the packaging box, which is made of paper, and the tape, which is made of synthetic resin.

Generally, roll tape is made up of a roll of tape wound around a paper tube, with adhesive applied to the underside of the tape, and is often used to seal packaging boxes in which items are packaged.

When manufacturing and shipping home appliances, furniture, or small items, such as refrigerators, printers, TVs, knock-down furniture, and food, the products are placed in packaging boxes and then the packaging boxes are taped and sealed to prevent damage during shipping.

When taping packaging boxes, a roll of tape is placed at the joint of the paper core of the cutter to make the work easier.

The advantage of using a cutter is that it is easy to cut the tape, making taping the packaging box very quick and convenient.

However, when the packaging box is opened, the tape attached to the packaging box must be removed again. At this time, the adhesive surface of the tape sticks to the surface of the packaging box, making it difficult to remove the attached tape from the packaging box.

To separate the adhered tape from the packaging box, a common method is to cut the tape with a tool such as a knife, or to manually peel the tip (end) of the tape away from the packaging box to separate the tape.

However, while the conventional method of cutting the adhered tape with a tool such as a knife is convenient, it cuts the adhered tape into several pieces, which is inconvenient because, if the packaging box is made of paper, the several pieces of tape must be manually separated and discarded one by one in order to separate and eject the packaging box. Also, the method of separating the tape by manually peeling off the end of the adhered tape from the packaging box is inconvenient because it takes a lot of time and can cause injury to the fingernails.

To eliminate many of these inconveniences, methods have been proposed to make it easier to remove the applied tape, and there are two main methods that have been proposed to make it easier to remove the applied tape.

The first method is to form a non-adhesive portion by folding one side end of the adhesive tape, and the second method is to form a non-adhesive portion by adhering an inner sheet to the tip of the adhesive tape.

First, the first method of forming a non-adhesive portion by folding the adhesive tape itself is disclosed in Korean Patent Nos. 10-0835541 (Registration Date: 2008.05.29), 10-0835542 (Registration Date: 2008.05.29), 10-0853867 (Registration Date: 2008.08.18), 10-1358418 (Registration Date: 2014.01.22), and 10-1412145 (Registration Date: 2014.06.19), etc.

The second method, which involves forming a non-adhesive portion by adhering an inner sheet to the inner end of the adhesive tape, is proposed in Korean Patent Registration No. 10-1358419 (registration date: 2014.01.22.).

However, with both of the above methods, a non-adhesive portion (inner sheet) is attached to the end of the adhesive tape, and during the packaging box delivery process at the logistics center, the non-adhesive portion is repeatedly touched, pulled or interfered with in various places, causing it to randomly separate (peel off) from the packaging box. This causes the packaging box to be randomly opened during transport, causing packaged items or contents to fall out and become damaged or broken.

In particular, the second method requires the user to hold the cutter with one hand and manually attach the inner sheet to the adhesive surface formed on the underside of the tip of the tape with the other hand, which is very inconvenient to use and significantly reduces the efficiency of taping packaging boxes.

The present invention has been made to improve the above problems, and the first problem that the present invention aims to solve is to provide an automatic inner sheet attachment type roll tape cutter that, when taping a packaging box, pushes a pressure member (pusher) installed on the tape cutter body to automatically attach the inner sheets located in the uppermost layer of the inner sheet storage box one by one to the adhesive surface (lower surface) of the tape, so that when a consumer opens the packaging box, he or she can easily peel off the tape from the packaging box using the inner sheet, thereby making it not only easy to open the packaging box but also very useful in terms of separating and collecting the paper packaging box and the synthetic resin material.

The second problem that the present invention aims to solve is to provide an inner sheet automatic attachment type roll tape cutter that can eliminate the previous problem caused by the tape randomly separating (peeling off) from the surface of the packaging box during the shipping and transportation process, since the tip of the tape taped to the packaging box does not lift off from the surface of the packaging box and remains in close contact even after the taping of the packaging box is completed.

The technical problems of the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, the roll tape cutter of the automatic inner sheet attachment type according to the preferred embodiment of the present invention is an inner sheet attachment type roll tape cutter that automatically attaches inner sheets (or tags) one by one to the underside of the tape during the taping of a packaging box, so that when a consumer opens the packaging box, the tape can be easily peeled off from the packaging box using the inner sheet attached to the tape. The cutter body has a tape paper core connection part at one end for rotatably placing a roll tape on which the tape is wound, and an inner sheet storage box holder at the other end; a handle that is connected to the cutter body so that the worker can hold it by hand during the taping of the packaging box; a guide roller that is rotatably installed at the tip of the cutter body so that the upper surface of the tape is pressed downward to tightly attach the tape to the packaging box during the taping of the packaging box; a tape pull-out guide for preventing the tape from sagging downward and for guiding the pull-out of the tape during the taping of the packaging box; an inner sheet storage box that is detachably installed in the inner sheet storage box holder and for sequentially discharging (pulling up or lifting up) the topmost inner sheet one by one during the taping of the packaging box when a number of inner sheets are stacked inside; a pressure member that is elastically pushed and installed on the cutter body so that the top surface of the tape is pressed during the taping of the packaging box and the topmost inner sheet is attached to the adhesive surface of the tape one by one and discharged; and a tape cutter for cutting the tape after the taping is completed.

When taping the packaging box, the lower end of the pressure member presses the upper surface of the tape by pressing the pressure member, and the inner sheets located in the uppermost layer of the inner sheet storage box are automatically attached to the lower surface of the tape one by one and discharged (pulled up or lifted up), and the taping work is completed with the inner sheets attached to the tape, so that when opening the packaging box, the user can easily peel off the tape from the packaging box using the inner sheets.

In addition, the position of the inner sheet storage box can be configured to be variable (repositionable) within the inner sheet storage box holder in order to adjust the attachment position of the inner sheet attached to the adhesive surface of the tape.

In addition, the inner sheet storage box holder may be formed with multiple locking holes, a locking protrusion that is elastically coupled to the locking hole may be installed on one side of the inner sheet storage box, and an unlocking button that unlocks the locking protrusion may be installed on the other side of the inner sheet storage box.

The inner sheet storage box may also include a base plate located at the bottom; a hollow guide channel having a stopper formed at the top end and connected to the top of the base plate; an up and down plate on which a number of the inner sheets are placed, which is installed inside the guide channel so as to be movable up and down and is prevented from coming off by the stopper; and a spring installed on the top of the base plate to elastically maintain the up and down movement of the up and down plate.

In addition, in order to maintain the balance of the up-down plate when the up-down plate moves up and down, a plurality of balance maintaining columns are formed on the base plate, and the springs are installed on the balance maintaining columns, and the springs are configured to uniformly support both ends of the up-down plate.

In addition, a flange for handle may be formed on the front of the inner sheet storage box to facilitate removal of the inner sheet storage box.

In addition, a remaining amount confirmation window is formed on the side of the inner sheet storage box so that the remaining amount of the inner sheet can be confirmed with the naked eye, and the inner sheet storage box can be formed to be inclined at 45 degrees.

In addition, a rib may be formed on the front surface of the inner sheet storage box holder to facilitate separation of the tape.

As explained above, the present invention has the following advantages:

First, when taping the packaging box, the pressure member is pressed so that the lower end of the pressure member presses the upper surface of the tape, and the inner sheets located in the top layer of the inner sheet storage box are automatically attached one by one to the adhesive surface (lower surface) of the tape and discharged (pulled up). By completing the taping work with the inner sheets attached to the lower surface of the tape, when the consumer opens the packaging box, they can easily peel the tape off the packaging box using the inner sheets. This not only makes it easy to open the packaging box, but is also extremely useful in terms of separating and collecting the packaging box, which is made of paper, and the tape, which is made of synthetic resin.

The second advantage is that the logo of each company is printed on the surface of the inner sheet attached to the tape, allowing consumers to easily identify the company's product after receiving the packaged box. Another advantage is that a sequence (number) can be written on the inner sheet, making it easy to peel off multiple tapes in reverse order.

Thirdly, even after taping of the packaging box is completed, the tip of the tape taped to the packaging box does not lift up from the surface of the packaging box and remains in close contact, eliminating the previous problem of the tape randomly separating (peeling off) from the surface of the packaging box during the shipping and transportation process.

Fourthly, the inside of the handle and the external protrusions are coated with rubber and urethane material to improve the grip, and when used in workplaces that require long periods of taping work (e.g., delivery and logistics companies), it can safely protect the hands of workers and reduce fatigue.

Fifth, the stopper on the inner sheet storage box is positioned appropriately so as not to interfere with the ejection (pulling up or lifting) of the inner sheet during the taping process of the packaging box, allowing the inner sheets to be ejected (pulled up or lifted up) one by one at the appropriate time, improving product reliability.

The sixth advantage is that a spring is installed on the balance column of the inner sheet storage box, which maintains the balance of the up-down plate and prevents it from tipping over. By supporting both ends of the up-down plate evenly, the inner sheet can be discharged smoothly.

Seventh, the inner sheet storage box has handle flanges on both ends on the front, making it very easy to pull the inner sheet storage box out and in.

Eighth, a remaining amount confirmation window is formed on the side of the inner sheet storage box, and the remaining amount of inner sheets can be checked through the remaining amount confirmation window, allowing the inner sheets to be refilled at the appropriate time.

The ninth feature is that the installation angle of the inner sheet storage box is inclined at approximately 45 degrees, which effectively prevents interference with the packaging box during taping, and by guiding the tape adhesive position as far as possible toward the end of the tape, tape usage is reduced and taping work is made easier.

The advantages of the present invention are not limited to those mentioned above, and other advantages not mentioned will be clearly understood by those skilled in the art from the claims.

Figure 14 is a perspective view for explaining the assembly of the pressure member of the present invention, Figure 15 is a plan view showing the shape of the inner sheet of the present invention, Figure 16 is a diagram showing various protruding positions of the inner sheet adhered to the tape, and Figures 17 and 18 are diagrams explaining the taping work of a packaging box using the inner sheet automatic attachment type roll tape cutter of the present invention.

In the drawing, the taping of a packaging box is described as an example, but the technology of the present invention can be equally applied to the taping of items other than packaging boxes.

The inner sheet automatic attachment type roll tape cutter 100 of the present invention can be variously changed to small size (a), medium size (b), and large size (c) as shown in Figures 2 to 4, and its shape can also be variously changed.

As is well known, the roll tape 10 can be composed of a paper sleeve 11 and a tape 12 wound around the paper sleeve 11. The upper surface 12a of the tape 12 is configured as a smooth surface, and the lower surface of the tape 12 is formed as an adhesive surface 12b.

As shown in Figures 1 to 4, the roll tape cutter 100 with automatic inner sheet attachment according to a preferred embodiment of the present invention is a tape cutting device that automatically attaches inner sheets 30 one by one to the underside (adhesive surface) 12b of the tape 12 during the taping operation of the packaging box 1 (see Figures 17 and 18), so that when a consumer opens the packaging box 1, the tape 12 attached to the inner sheet (or tag or label sheet) 30 attached to the tape 12 can be easily peeled off, making it easy to open the packaging box.

With reference to FIG. 1 and FIG. 5 to FIG. 15, the configuration of the roll tape cutter 100 of the automatic inner sheet attachment type according to the preferred embodiment of the present invention will be considered. The roll tape cutter 100 of the automatic inner sheet attachment type according to the present invention includes a cutter body 110 for placing the roll tape 10; a handle 117 that can be held by the operator; a guide roller 120 for pushing the upper surface of the tape 12 downward during the taping operation of the packaging box 1; a tape pull-out guide 130 for guiding the pulling out of the tape 12; an inner sheet storage box 140 for sequentially discharging (pulling up) the topmost inner sheet 30 one by one during the taping operation of the packaging box 1 with a plurality of inner sheets 30 stacked inside; a pressure member 150 for allowing the topmost inner sheet 30 to be attached to the lower surface of the tape one by one and discharged during the taping operation of the packaging box 1; and a tape cutting unit 160 for cutting the tape 12 after the taping operation is completed.

Explaining further with reference to Figures 5 to 7, a tape paper core coupling part 112 for rotatably mounting (installing) the roll tape 10 is formed at the rear end of the cutter body 110, and a shaft 118 is formed on the upper side of the tip of the cutter body 110. An inner sheet storage box holder 115 is formed on the lower side of the tip of the cutter body 110, and a guide roller 120 is rotatably mounted on the shaft 118.

The inner sheet storage box holder 115 opens toward the front, and the inner sheet storage box 140 is configured to be inserted into the open portion in a sliding manner.

The tape paper core joint 112 may be formed with a separation prevention protrusion 113 to prevent the roll tape 10 from accidentally separating (falling out) from the tape paper core joint 112.

It is preferable that the tape/cardboard core joint 112 be formed into various shapes, such as a heart shape, to make the appearance even more beautiful.

Referring also to Figures 1 and 7, the handle 117 is attached to the upper side of the cutter body 110 so that the worker can hold it by hand when taping the packaging box 1.

The handle 117 is rotatably connected to the cutter body 110 by a structure in which hinges 117a (see FIG. 13) are fitted to both ends of the shaft 118, and is configured to rotate a certain angle based on the hinges 117a.

That is, the handle 117 is configured to be separated from the cutter body 110, making it easy to hold and facilitate taping operations. In addition, it is preferable that the inside and external protrusions of the handle 117 are coated with rubber and urethane material 114 to improve the grip.

The rubber and urethane material 114 not only provides a good grip, but also safely protects the hands of the worker and reduces fatigue when used in workplaces where long periods of taping work are required (e.g., home delivery and logistics companies).

Referring further to FIG. 1, FIG. 4 and FIG. 7, the guide roller 120 presses the upper surface of the tape 12 downward during the taping operation of the packaging box 1. The guide roller 120 may be rotatably installed on the tip of the cutter body 110, more precisely, on the shaft 118, so that the tape 12 can be tightly attached to the packaging box 1.

When taping the packaging box 1, the guide roller 120 applies downward pressure to the top surface of the tape 12 to make the tape 12 adhere tightly to the packaging box 1, and the rotation of the guide roller 120 ensures smooth taping.

The tape pull-out guide 130 shown in Figs. 4 to 7 may be formed on the cutter body 110 to prevent the tape 12 from sagging downward and to guide the pulling of the tape 12 during the taping operation of the packaging box 1. The installation position of the tape pull-out guide 130 is not limited to the cutter body 110, and although not shown in the drawings, the tape pull-out guide 130 may be formed on the handle 117.

The tape pull-out guide 130 may be formed of at least one or more members. In addition, the tape pull-out guide 130 functions to reinforce the durability of the cutter body 110, maintains a constant distance between the tape 12 and the inner sheet 30, and serves to guide the pull-out of the tape 12.

As shown in FIG. 6, when the tape pull-out guide 130 guides the tape 12, static electricity is generated due to friction between the tape pull-out guide 130 and the tape 12. However, this static electricity keeps the end of the tape 12 in a straight line facing upward, making it very easy to tape the end of the tape 12 to the packaging box 1 at the beginning of the taping work for the packaging box.

The position of the inner sheet 30 (see Figures 15 and 16) that adheres to the tape 12 is preferably 3 to 4 cm from the end of the tape 12, because this is the optimal position when the tape 12 is peeled off from the packaging box 1 without interfering with the adhesive strength of the tape 12.

Referring further to Figures 9 to 11, the inner sheet storage box 140 can be detachably installed in the inner sheet storage box holder 115 in a sliding manner. When a number of inner sheets 30 are stacked inside the inner sheet storage box 140, the top of the inner sheet storage box 140 is opened to sequentially discharge (pull up) the topmost inner sheet 30 one by one during the taping operation of the packaging box 1.

Considering the configuration of the inner sheet storage box 140, the inner sheet storage box 140 may be configured to include a base plate 141 located at the bottom; a hollow guide channel 142 having a stopper 142a formed at the upper end and connected to the top of the base plate 141; an up-down plate 143 on which a number of inner sheets 30 are placed, which is installed inside the guide channel 142 so as to be movable up and down and is prevented from coming off by the stopper 142a; and a spring 144 installed on the top of the base plate 141 to elastically maintain the up and down movement of the up-down plate 143.

A number of inner sheets 30 are stacked on the up-down plate 143, and the springs 144 elastically support the up-down plate 143, while the stoppers 142a prevent the inner sheets 30 from accidentally detaching.

The stopper 142a must be formed in an appropriate position and manufactured to an appropriate size so as not to interfere with the discharge (pulling up or lifting) of the inner sheet 30 when the pressure member 150 is pressed to attach the top inner sheet 30 to the adhesive surface 12b of the tape 12 during the taping operation of the packaging box 1 (in the inner sheet attachment mode). For example, the position of the stopper 142a is preferably formed to extend inward from the frame, and the size and shape of the stopper 142a are preferably formed to be small and round.

In order to maintain the balance of the up-down plate 143 when the up-down plate 143 moves up and down, i.e., to prevent the up-down plate 143 from tipping over, a plurality of balance maintaining columns 145 are further formed on the base plate 141, and springs 144 are installed on the balance maintaining columns 145, and the springs 144 uniformly support both ends of the up-down plate 143.

It is preferable that handle flanges 146 are further formed on both front ends of the inner sheet storage box 140 to facilitate pulling out or inserting the inner sheet storage box 140. The handle flanges 146 serve to allow the user to conveniently pull out or insert the inner sheet storage box 140 using the thumb and middle finger.

The side of the inner sheet storage box 140 is formed with a remaining amount confirmation window 147 so that the remaining amount of the inner sheet 30 can be confirmed with the naked eye, so that the user can refill the inner sheet 30 at the appropriate time while checking the remaining amount of the inner sheet 30 through the remaining amount confirmation window 147.

The installation angle of the inner sheet storage box 140 is inclined at about 45° (see FIG. 3), which effectively prevents interference with the packaging box 1 during taping, and the adhesive position of the tape 12 is guided as far as possible toward the end of the tape, reducing the amount of tape used and making taping easier.

Referring to FIG. 12, the upper side of the inner sheet storage box holder 115 may be formed with a number of first ribs (or creases) 148 that facilitate separation of the tape 12. The first ribs 148 allow the tape 12 to be easily attached and detached, making it very convenient to use.

A second rib (or wrinkled portion) 149 may be formed on the lower side of the side of the inner sheet storage box holder 115. When taping the packaging box, the second rib 149 is placed on the edge of the packaging box 1 and then pressed to perform the taping operation, so there is no need for the user to press the packaging box 1 by hand as in the past, making the taping operation very easy (see FIG. 17).

As shown in FIG. 8 and FIG. 15, the inner sheet 30 is configured as a sheet paper (label sheet) manufactured in a certain size and various shapes, and can be refilled in the inner sheet storage box 140. Also, the inner sheet 30 can be made of paper, vinyl, etc.

The inner sheet 30 can be printed on its surface, and the different colors can be used to improve visibility, making it easier for workers to find and remove the tape from the packaging box 1. The shape of the inner sheet 30 can be changed to, for example, a polygon (a), a round shape (b), and various designs (c, d). In order to minimize interference when pulling out (pulling up) the inner sheet 30, it is preferable to cut the corners of the inner sheet 30 and form the shape of the inner sheet 30 into a round shape.

Although not shown in the drawings, the inner sheets 30 can be printed with the logos and letters of each company, allowing consumers to easily identify the packaged product after receiving the packaging box 1 delivered to their home. When taping the packaging box, each inner sheet 30 is attached to each of the intersecting tapes 12, and the order is written on each inner sheet 30, so that multiple tapes 12 can be easily peeled off in reverse order. In other words, the order (numbers) can be written on the inner sheets 30, allowing the taped tapes to be easily peeled off.

Also, as shown in FIG. 2 and FIG. 16, the position of the inner sheet storage box 140 can be configured to be variable within the inner sheet storage box holder 115 in order to adjust the attachment position of the inner sheet 30 attached to the adhesive surface 12b of the tape 12. Here, adjusting the attachment position of the inner sheet 30 means that the inner sheet 30 protrudes shorter or longer from the tape 12. The reason for this is to prevent the inner sheet 30 from getting caught or interfering with the conveyor when sorting packaging boxes at a logistics center, or to allow the protruding position of the inner sheet 30 to be appropriately adjusted according to the consumer's preferences.

In order to change the position of the inner sheet storage box holder 115 in this manner, the inner sheet storage box holder 115 is formed with multiple locking holes 171, a locking protrusion 172 that is elastically coupled to the locking hole 171 is provided on one side of the inner sheet storage box 140, and an unlock button 173 that unlocks the locking protrusion 172 is provided on the other side of the inner sheet storage box 140. The position of the inner sheet storage box holder 115 can be adjusted by inserting the locking protrusion 172 into any one of the multiple locking holes 171. The unlock button 173 is configured with a structure that allows the user to easily press it using the index finger.

As shown in FIG. 10, the unlock button 173 is elastically supported by a spring 173a on the front side of the base plate 141, and the unlock button 173 and the locking protrusion 172 are configured to maintain contact on the inclined surface 173b. When the user presses the unlock button 173 and the unlock button 173 advances or returns to its original position, the locking protrusion 172 can be inserted into one of the locking holes 171 while appearing and retracting (moving forward and backward) due to the inclined surface 173b.

As shown in Figures 12 to 14, the pressure member 150 is installed in the cutter body 110 so that it can be elastically pushed against the cutter body 110 so that the uppermost inner sheet 30 adheres one by one to the adhesive surface 12b of the tape 12 during the taping operation of the packaging box 1.

The pressure member 150 is slidably installed within the support structure 118 and configured to be elastically pressed by a spring (not shown). The support structure 118 is connected to the handle 117 by a bolt B.

The head 151 of the pressure member 150 protrudes outside the handle 117. The pressure member 150 is arranged in a diagonal direction, and when the user grips the handle 117, the head 151 is arranged to be placed at the position of the user's index finger (second finger), making taping very convenient.

Although not shown in the drawings, a design change could position the head portion 151 so that it is placed at the user's thumb position.

Also, as shown in Figures 1 and 2, a tape cutting portion 160 may be provided at the tip of the handle 117 for cutting the tape 12 after the taping operation is completed.

The tape cutting portion 160 may be integrally formed at the tip of the cutter body 110 or may be attached separately. The tape cutting portion 160 may be formed in a knife or sawtooth shape, etc.

Meanwhile, as shown in Figures 17 and 18, after placing an item in the packaging box 1 (a), in the past, the user had to press the top of the packaging box by hand before taping (b), but in the present invention, the second rib 149 (see Figure 12) is placed on the edge of the packaging box 1 (c), and then the cutter 100 of the present invention can be pressed downward to perform the taping work (d). Therefore, since the user does not need to press the packaging box 1 by hand as in the past, the taping work is very convenient.

In the roll tape cutter 100 with automatic inner sheet attachment according to the preferred embodiment of the present invention, the roll tape 10 is inserted into the tape paper core connection part 112 of the cutter body 110 and placed there, and then the tip (frontmost part) of the tape 12 is pulled and pulled out to the front side of the cutter body 110 (see Figures 2 to 4).

During the taping operation of the packaging box 1, the second rib 149 (see Figs. 12 and 17) is placed on the edge of the packaging box 1 (c), and the cutter 100 is pressed downward to perform taping, and the adhesive surface 12b of the tip of the tape 12 is attached to the surface of the packaging box 1, and then the guide roller 120 presses the upper surface of the tape 12 downward to make the tape 12 adhere to the packaging box 1, and at the same time, the cutter body 110 is pulled in the direction of the arrow (rearward) (see Fig. 17). Next, when the pressure member 150 is pressed, the lower end of the pressure member 150 presses the tape 12 downward, and the inner sheets 30 located in the uppermost layer of the inner sheet storage box 140 are automatically attached one by one to the adhesive surface 12b of the tape 12 and discharged (pulled up), and the taping operation is completed with the inner sheets 30 attached to the end of the tape 12 (see Fig. 18).

In addition, even after taping of the packaging box 1 is completed, the tip of the tape 12 taped to the packaging box 1 does not lift off from the surface of the packaging box 1 and remains in close contact, eliminating the previous problem that occurs when the tape 12 is randomly separated (peeled off) from the surface of the packaging box 1 during the delivery or transportation process of the packaging box 1.

In addition, when a consumer opens the packaging box 1, there is no need to cut the tape using a tool such as a knife to separate the attached tape from the packaging box as in the past. The tape 12 can be easily peeled off from the packaging box 1 using the inner sheet 30, and since no tape 12 remains on the packaging box 1, this is extremely useful in terms of separating and collecting the packaging box 1, which is made of paper, and the tape 12, which is made of synthetic resin.

As explained above, the present invention has the following advantages:

First, when taping a packaging box, the pressure member is pressed so that the lower end of the pressure member presses the upper surface of the tape, and the inner sheets located in the top layer of the inner sheet storage box are automatically attached one by one to the adhesive surface (lower surface) of the tape and discharged (pulled up). By completing the taping work with the inner sheets attached to the lower surface of the tape, when the consumer opens the packaging box, they can easily peel the tape off the packaging box using the inner sheets. This not only makes it easy to open the packaging box, but is also extremely useful in terms of separating and collecting the packaging box, which is made of paper, and the tape, which is made of synthetic resin.

The second advantage is that the logo of each company is printed on the surface of the inner sheet attached to the tape, allowing consumers to easily identify the company's product after receiving the packaged box. Another advantage is that a sequence (number) can be written on the inner sheet, making it easy to peel off multiple tapes in reverse order.

Thirdly, even after taping of the packaging box is completed, the tip of the tape taped to the packaging box does not lift up from the surface of the packaging box and remains in close contact, eliminating the previous problem of the tape randomly separating (peeling off) from the surface of the packaging box during the shipping and transportation process.

Fourthly, the inside of the handle and the external protrusions are coated with rubber and urethane material to improve the grip, and when used in workplaces that require long periods of taping work (e.g., delivery and logistics companies), it can safely protect the hands of workers and reduce fatigue.

Fifth, the stopper on the inner sheet storage box is positioned appropriately so as not to interfere with the discharge (pulling up or lifting) of the inner sheet during the taping process of the packaging box, allowing the inner sheets to be discharged (pulled up or lifted up) one by one at the appropriate time, improving product reliability.

The sixth advantage is that a spring is installed on the balance column of the inner sheet storage box, which maintains the balance of the up-down plate and prevents it from tipping over. By supporting both ends of the up-down plate evenly, the inner sheet can be discharged smoothly.

Seventh, the inner sheet storage box has handle flanges on both ends on the front, making it very easy to pull the inner sheet storage box out and in.

Eighth, a remaining amount confirmation window is formed on the side of the inner sheet storage box, and the remaining amount of inner sheets can be checked through the remaining amount confirmation window, allowing the user to refill the inner sheets at the appropriate time.

Ninth, the installation angle of the inner sheet storage box is inclined at about 45 degrees, which effectively prevents interference with the packaging box during taping work, and by guiding the tape adhesion position as far as possible toward the end of the tape, tape usage is reduced and taping work is made easier.
