Description

Adhesive tape holder structure with adhesive tape fixing part

Technical Field

The present invention relates to an adhesive tape dispenser, and more particularly to an adhesive tape dispenser capable of preventing an adhesive tape roll inserted into the adhesive tape dispenser from reversely rotating in a direction opposite to the unwinding direction of an adhesive tape.

Background

In sealing a box or the like containing an article, it is common to join and seal the box or the like by adhering a tape roll to a cut portion of a lid portion of the box.

The above-mentioned case sealing method is generally performed by manual work of an operator using a roll type tape dispenser.

However, the roller-type tape holder of the prior art has a problem that since the blade (blade edge) is horizontally disposed, cutting force cannot be effectively transmitted to the tape when the tape is cut, and the tape cannot be cut at one time, so that the tape can be cut by applying force several times.

In order to solve the above problems, the applicant of the present patent has developed "tape dispenser" of korean patent No. 10-1649461 in which a cutter blade portion is formed with a prescribed inclination to improve cutting force.

Fig. 1a and 1b show a tape dispenser 1 with improved cutting force according to the prior art.

Fig. 1a is a schematic view showing a state where an adhesive tape is inserted into the tape dispenser 1, and as shown in the figure, a tape roll 2 is inserted into a circular drum 10' provided at a lower end of the tape dispenser 1, and when a worker moves the tape dispenser along a desired adhesion portion, the tape roll 2 is unwound while rotating, and the unwound tape 2 is guided by a guide roller 20 to be unwound and adhered to the adhesion portion, and when the adhesion portion is finished, the tape is cut at a desired length by a cutter blade at a corresponding position.

Fig. 1b is a schematic view showing a shape of the tape dispenser 1 according to the related art in which the tape roll 2 is removed, and as shown in the drawing, the surface of the drum 10' into which the tape roll 2 is inserted is smooth so that the tape roll 2 can be smoothly inserted without hindrance and the tape roll 2 can be smoothly rotated.

However, since the surface of the drum 10 'is free from any blockage, the adhesive tape roll 2 inserted into the drum 10' can be rotated in both directions.

Therefore, as shown in fig. 1a, the tape roll 2 is normally rotated and unwound in the direction of arrow a, but may be rotated in the direction of arrow b, i.e., in the reverse direction.

When the tape roll 2 is rotated in the reverse direction, the cut front end portion drawn from the tape roll 2 is rewound into the tape roll 2 and adhered to the tape roll 2, and when the tape roll is used later, the front end portion adhered to the tape roll needs to be found and peeled from the tape roll 2, tensioned, and then adhered to a large sheet again, which is troublesome.

The above-mentioned cumbersome process requires a considerable time, thereby causing a great hindrance to quickly perform the taping work.

Further, when the tape roll 2 is rotated in the reverse direction, the tape cannot be unwound smoothly, and the tape roll 2 is cut at an incorrect position when cut, so that a desired length cannot be cut.

Detailed Description

The present invention will be described in detail with reference to the preferred embodiments and the accompanying drawings, wherein like reference numerals denote like structures.

In the detailed description of the present invention or the claims, when a component is referred to as being "included" in a certain portion, the component is not limited to be included, and may include other components unless the contrary is intended.

An example of realizing a tape holder having a tape fixing portion will be described below with reference to specific embodiments.

Fig. 2 is an overall view of the adhesive tape dispenser with the adhesive tape fixing portion according to the present invention.

In one aspect, the tape dispenser is similar in structure to the tape dispenser of the prior art, but includes a cutting portion 110 for cutting a section of one side of the drum 10 inserted into the tape roll 2, unlike the prior art.

The cut-out portion 110 is formed by cutting out a predetermined section of the circular wall surface constituting the drum 10 in a direction perpendicular to the direction in which the adhesive tape rotates.

Here, the protrusion 120 is formed as a structure separated from the wall surface of the drum 10 by the cut-out portion 110.

The protrusion 120 protrudes further outward than the wall surface of the drum 10, and thus is formed to protrude differently from the wall surface of the drum 10.

The protrusion portion 130 is formed to protrude at a predetermined height from the upper surface of the protrusion portion 120, and the protrusion portion 130 has a longitudinal direction parallel to the direction in which the incision portion 110 is incised.

The protrusion 130 is in contact with the roll inner side of the tape roll 2 after the tape roll 2 is inserted, while ensuring the unobstructed insertion of the tape roll 2 by the protrusion 120 when the tape roll 2 is inserted.

The cut-out portion 110 and the protrusion portion 130 at the level of the protrusion portion 120 form a fixing portion for preventing the reverse rotation of the lower roll 2.

Fig. 3 is an enlarged view of the fixing portion.

As shown in fig. 3, the cut portion 110 is cut from one end of the wall surface of the drum 10, traverses the wall surface toward the other end, and ends at a position before reaching the other end, so that a partial section on the other side is not cut.

That is, the cut-out portion 110 has a structure in which one end is open (hereinafter, referred to as an "open portion 111") and the other end is closed (hereinafter, referred to as a "closed portion 112").

The closed portion of the other-side end, which is not cut, functions as a shaft when the protrusion 120 moves inward and outward while the protrusion 120 formed by the cut 110 is supported without being completely separated in the drum 10.

The protrusion 120 formed by the cut-out portion 110 is formed to be inclined outward in a direction from the closed portion 112 of the cut-out portion 110 toward the open portion 111, so that the end of the cut-out portion 110 located on the open portion 111 side is raised and protruded outward of the drum 10.

The protruding portion 120 repeatedly pushes the both side closing portions 112 of the cut portion 110 toward the inside of the drum 10 and then lifts the same toward the outside using the same as a support bar and a shaft.

This is to press the protruding portion 120 when the tape roll 2 is inserted into the drum 10, and to restore the protruding portion 120 again by elasticity when the tape roll 2 is removed, thereby repeating the above-described operation.

Here, when the tape roll 2 is inserted into the drum 10 and pressed, the protrusion 120 generates a restoring force by elasticity, and the elastic force is applied in the outer direction of the drum 10, and finally, a force pushing the outer side of the drum 10 is applied to the roll inner side of the tape roll 2 by the protrusion 120, thereby fixing the tape roll 2.

The protrusion 130 formed on the upper surface of the protrusion 120 directly contacts the inner side of the tape roll 2 when the tape roll 2 is inserted into the drum 10.

Fig. 4a, 4b, and 4c are enlarged views of the protrusion 130 when the adhesive tape roll 2 is inserted into the drum 10, fig. 4a is an enlarged view of the protrusion 130 as viewed from the front, and fig. 4b and 4c are enlarged views of a cross section of the protrusion 130 as viewed from one side.

As shown in the drawing, the upper end of the protrusion 130 contacts the inner side of the tape roll 2, and transmits the elastic force generated by the protrusion 120 to the tape roll 2.

That is, the adhesive tape roll 2 is fixed while applying a force in a direction of pushing the roll inner side of the adhesive tape roll 2 to the outer side of the drum 10 to the protrusion 130 formed at the upper end of the protrusion 120.

Here, the protrusion 130 is formed to be inclined at a predetermined angle in the same direction as the rotation direction of the tape roll 2, with reference to the case where the protrusion is perpendicular to the protruding portion.

The end of the projection 130 is also inclined at a predetermined angle in the same direction as the direction in which the tape roll 2 rotates. As shown in fig. 4a, the tape roll 2 is rotated in the direction of arrow a, and the protrusion 130 is also formed to be inclined in the rotation direction of the tape roll 2 with respect to the direction perpendicular to the protrusion 120.

Here, since the direction in which the protrusion 130 is inclined is the same as the rotation direction, the inner side of the tape roll 2 contacting the protrusion 130 is not blocked by the protrusion 130 when the tape roll 2 rotates, thereby ensuring smooth rotation of the tape roll 2.

On the contrary, when the tape roll 2 is rotated in the b direction, that is, the protrusion 130 is rotated in the direction opposite to the inclined direction, the inner side of the tape roll 2 contacting the protrusion 130 is caught by the protrusion 130, and the rotation in the b direction becomes difficult. Therefore, since the protrusion 130 is inclined in the same direction as the rotation direction of the tape roll 2, the reverse rotation of the tape roll 2 can be prevented.

The end of the projection 130 is also inclined by a predetermined angle in the same direction as the rotation direction of the tape roll 2.

This corresponds to a case where the protrusion 130 is formed to be inclined at a predetermined angle in the same direction as the direction in which the adhesive tape roll 2 rotates.

If one end surface of the projection 130 is flat, the area of the end surface of the projection 130 contacting the inner side of the tape roll 2 becomes very narrow due to the inclination of the projection 130, and the friction force is reduced, thereby reducing the effect of preventing the reverse rotation.

At the same time, since the tip of the projection on the one side and the portion in close contact with the inner side of the tape roll 2 form an acute angle, the tape roll is prevented from rotating reversely when rotating in the direction a (forward rotation).

On the other hand, the distal end surface on the side of the projection is formed to be inclined at the same angle as or similar to the predetermined angle at which the projection 130 is inclined in the same direction as the inclination of the projection 130, so that the distal end surface of the projection 130 which is in close contact with the inner side of the adhesive tape roll 2 is increased in area.

Thereby, the friction between one side end of the protrusion 130 and the inner side of the tape roll 2 is increased, thereby preventing the reverse rotation more effectively.

Since the direction of inclination is the same as the direction a (normal rotation), the tape roll 2 does not interfere with the rotation when it is rotated in the normal direction.

Further, since the diameter of the tape roll 2 is slightly different depending on products, when the tape roll 2 is inserted into the drum 10 to press the protrusion 130, the degree of pressing is different depending on the diameter of the tape roll 2.

Therefore, in the present invention, the protrusion 130 is inclined at a predetermined angle while being raised from one side to the other side in the longitudinal direction, so that the tape roll 2 can be easily inserted and fixed even when the pressing degree is different.

Fig. 4b and 4c are enlarged views of the state of the protrusion 130 when the adhesive tape rolls 2 having different diameters are inserted into the drum 10, and fig. 5a and 5b are enlarged views of the state of the protrusion 130 when the adhesive tape rolls are viewed from the front under the same condition, and the following description will be made in more detail with reference to fig. 4b, 4c, 5a and 5 b.

Fig. 4b shows a state where the tape roll 2 'having a relatively large diameter is inserted, and the diameter is relatively large, so that the degree of pressing the protrusion 130 against the inner side of the tape roll 2' is relatively weak, and the protrusion 120 is relatively small downward. This corresponds to fig. 5b, which is relatively less pressed and thus located in a relatively high position with respect to fig. 5 a.

On the contrary, fig. 4c shows a state where the tape roll 2 'having a relatively small diameter is inserted, and the diameter is relatively small, so that the inner side of the tape roll 2' presses the protrusion 130 relatively strongly, and the protrusion 120 is downward relatively much. This corresponds to fig. 5a, being pressed more in relation to fig. 5b and thus being in a relatively low position.

At this time, since the height of the protrusion 130 is gradually decreased from the left side to the right side (see fig. 4b and 4c), when the tape roll 2' having a relatively large diameter is inserted, the right side having a low height does not contact the inner side of the tape roll 2, thereby forming the space 30.

When a tape having a relatively large diameter is inserted into the space 30 and the protrusion 130 is pressed more strongly by the inner side of the tape roll 2, the protrusion 120 can be pressed downward by the space.

As shown in the lower ends of fig. 4b and 4c, the protrusion 120 is pressed more strongly, so that the protrusion moves downward to the extent of the space 30, the space disappears, and the upper surface of the protrusion 130 comes into contact with the adhesive tape roll 2.

Unlike the present invention, if the protrusion 130 is formed horizontally, the space 30 or the formed small space is not formed, and thus, compared with the present invention, the adhesive tape of various sizes cannot be accommodated.

In addition, in order to prevent the reverse rotation, it is necessary to generate sufficient frictional force at the contact portion between the adhesive tape roll 2 and the protrusion 130, and therefore, it is preferable that one or more protrusions 130 are formed on the upper surface of the protrusion 120.

The technical idea of the present invention is explained above by means of several embodiments.

The utility model discloses the technical personnel in the field can follow the utility model discloses record the matter, can be right the embodiment carries out various deformation or changes. Although not explicitly shown or described, those skilled in the art can make various modifications including the technical idea of the present invention from the additional description items of the present invention, which fall within the scope of the present invention. The embodiments described above with reference to the drawings are illustrative of the present invention, and the scope of the present invention is not limited by these embodiments.
