Description

Adhesive sheet {Adhesive sheet}

The present invention relates to an adhesive sheet.

In general, wet tissues, tissues, mask packs, etc. (hereinafter referred to as wet tissues, etc.) are marketed by stacking a plurality of wet tissues in a case storing the wet tissues and the like. On the other hand, the upper surface of such a case is generally formed with an outlet for taking out wet tissues or the like.

On the other hand, the user holds the wet tissue exposed to the external space through the outlet with one hand and withdraws it from the case. At this time, since the user withdraws the wet tissues from the case, the loading amount of the wet tissues inside the case is gradually reduced. Accordingly, the total weight of the wet tissue and the case storing it is gradually reduced in the course of use. When the weight reduction amount of the case storing the wet tissues or the like is greater than a predetermined amount, the case may be lifted by the force of taking out the wet tissues or the like.

An object to be solved by the present invention is to provide an adhesive sheet in which a user can conveniently take out a wet tissue or the like from a case with one hand and stably fix it, regardless of a decrease in the amount of the wet tissue or the like.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the art to which the present invention pertains It is provided to fully inform those who have the scope of the invention, and the present invention is only defined by the scope of the claims.

In addition, the embodiments described herein will be described with reference to cross-sectional and/or schematic diagrams that are ideal illustrative views of the present invention. Accordingly, the form of the illustrative drawing may be modified due to manufacturing technology and/or tolerance. In addition, in each of the drawings shown in the present invention, each component may be enlarged or reduced to some extent in consideration of convenience of description. Like reference numerals refer to like elements throughout.

A 'case' referred to below is a container for storing a plurality of drawables therein. For example, the case may be configured to include any one or one or more of widely used materials such as paper, plastic wrapper, synthetic resin, and plastic.

At this time, here, the object to be drawn out is an object drawn out of the case in a drawing method. For example, the to-be-drawn object may be wet wipes, a tissue, a facial mask, an alcohol swab, or the like.

Meanwhile, a draw-out hole through which an object to be drawn is drawn may be formed at an upper portion of the case. In addition, a plurality of draw-outs may be stacked in a manner that intersects each other inside the case. For this reason, when one to-be-drawn object is drawn out by the user, the to-be-drawn-out stacked immediately below may be moved in the direction of the draw-out port together with the to-be-drawn object drawn out by the user by frictional force, and may be exposed outside the draw-out port. In such a case, a user who withdraws a draw-out could easily withdraw a draw-out by fixing the case by hand or fixing it to another external structure.

Taking wet wipes as an example, the more the user uses the wipes, the less the load amount of the wipes in the wet tissue case is. Due to this, the total weight, which is the sum of the weight of the wet tissue case and the weight of the wet tissues loaded inside the wet tissue case, will be continuously reduced. On the other hand, when the wet tissue is drawn out, a frictional force is generated between the outlet and the wet tissue. When the total weight of the wet tissue case is reduced by a predetermined amount or more, the frictional force between the wet tissue and the outlet becomes greater than the force due to the total weight.

At this time, when the adhesive sheet 1 according to an embodiment of the present invention is not used, the user holds the wet tissue with one hand and the wet tissue case with the other hand to apply a separate external force to the wet tissue case to withdraw the wet tissue. should provide

On the other hand, when the adhesive sheet 1 according to an embodiment of the present invention is used, the adhesive sheet 1 fixes the wet tissue case to an external object based on the adhesive force. That is, the adhesive sheet 1 provides a force in the direction of the external object to the wet tissue case based on the adhesive force. Accordingly, even if the total weight is reduced according to use, the user can withdraw the wet tissue from the wet tissue case using only one hand.

Hereinafter, the present invention will be described with reference to the drawings for explaining the pressure-sensitive adhesive sheet according to an embodiment of the present invention.

<Composition of adhesive sheet>

1 is a plan view of an adhesive sheet according to an embodiment of the present invention. In contrast, Figure 2 is a bottom view of the pressure-sensitive adhesive sheet according to an embodiment of the present invention. 1 and 2 , the adhesive sheet 1 according to an embodiment of the present invention may include an attachment part 11 and an attachment sheet 13 .

Here, the attachment part 11 is defined as a part configured so that one side of the adhesive sheet 1 according to an embodiment of the present invention can be separated from the surface of the base layer 10 . Specifically, one side of the attachment portion 11 is configured to be detachable on the base layer surface, and the other side is connected to a portion of the base layer 10 outside the first incision line 30 to be described later. In contrast, the attachment sheet 13 may be defined as a region excluding the attachment portion 11 on the base layer 10 .

On the other hand, when describing the layers constituting the adhesive sheet 1 according to an embodiment of the present invention, the adhesive sheet 1 according to an embodiment of the present invention includes a base layer 10 and an adhesive layer 20 . includes

First, the base layer 10 is a sheet that determines the overall shape of the adhesive sheet (1). Specifically, the base layer 10 may be made of a material having elasticity that can be deformed according to the shape of the attachment surface. 1 and 2, the shape of the base layer 10 is shown as having a substantially rectangular shape, but the present invention is not limited thereto. have.

For convenience of description, referring to FIG. 1 for the directions mentioned below, the front of the base layer 10 is the direction of the arrow H. On the other hand, the back side of the base layer 10 is in the direction of arrow B. On the other hand, the left side of the base layer 10 is the arrow L direction, and the right side of the base layer 10 is the arrow R direction.

Referring to FIG. 2 , the adhesive layer 20 is a layer attached to at least a portion of one surface of the base layer 10 . For example, the adhesive layer 20 may be provided by applying an adhesive on one surface of the base layer 10 . At this time, the adhesive having too strong adhesive force may tear the base layer 10 due to the adhesive force in the process of detaching the adhesive sheet 1 from an external object. In the opposite case, the adhesive sheet 1 does not sufficiently fix the case. may not be able to Accordingly, the pressure-sensitive adhesive may be selected to have an adhesive strength that can be detachably attached to the external structure without damaging the pressure-sensitive adhesive sheet 1 .

On the other hand, in order to distinguish the above-described attachment portion 11 from the attachment sheet 13, the base layer 10 of the adhesive sheet 1 according to an embodiment of the present invention has a first cut-out line 30 in the thickness direction. can be cut along the

Specifically, the first cut-out line 30 is a line that cuts the adhesive sheet 1 in the thickness direction so that the attachment part 11 and the attachment sheet 13 are distinguished. When described with reference to the first incision line 30 , the attachment part 11 is a portion of the base layer 10 on the inner side of the first incision line 30 in the adhesive sheet 1 . In contrast, the attachment sheet 13 is a part of the base layer 10 located in the outer region of the first incision line 30 .

Specifically, the first incision line 30 cuts the base layer 10 along an open path. Here, the first incision line 30 may be formed such that the open portion faces the front H of the base layer 10 . For this reason, in the attachment part 11 , the part connected to the attachment sheet 13 is located on the front side of the adhesive sheet 1 , and the other side of the attachment part 11 detaching from the base layer surface is of the adhesive sheet 1 . will be located on the rear side.

In addition, the first incision line 30 may cut the base layer 10 so as to be symmetrical left and right. Specifically, the base layer 10 is cut by drawing a gentle curve on the first incision line 30 . At this time, at least some of the left and right symmetric points of the first incision line 30 may be configured to have different left and right widths. For example, the first incision line 30 may be formed to include a section in which the width of the symmetric point increases from the front to the rear of the base layer 10 .

Hereinafter, in order to describe the shape of the first incision line 30 in more detail, the first incision line 30 is formed with the 1A incision line 31 located on the left side with respect to the left-right symmetry axis of the base layer 10 and It will be described by dividing by the 1B incision line 33 located on the right side. At this time, if described based on the 1A incision line 31 and the 1B incision line 33 , the attachment part 11 is a base layer located between the 1A incision line 31 and the 1B incision line 33 ( 10) is part of it.

Specifically, the first incision line 30 may have a plurality of sections defined according to the interval between the 1A incision line 31 and the 1B incision line 33 . For example, the plurality of sections may include a parallel section 30a, an extended section 30b, and a reduced section 30c.

First, the parallel section 30a is a section in which the interval between the 1A incision line 31 and the 1B incision line 33 is constant, starting from the open portion of the first incision line 30 . In addition, the expansion section 30b is a section in which the interval between the 1A cut-out line 31 and the 1B cut-out line 33 is widened to the rear of the base layer 10 after the parallel section 30a. In addition, in the reduction section 30c, after the expansion section 30b, the interval between the 1A incision line 31 and the 1B incision line 33 becomes narrower. Ultimately, the 1A incision line 31 and the 1B incision line 33 ) is a section that meets on the left and right axis of symmetry of the base layer 10 . This may be to increase the adhesive force of the attachment part 11 as will be described later, and details will be described later.

At this time, if the attachment part 11 is described based on the above-mentioned sections, the attachment part 11 is a parallel section 30a part, an expansion section 30b part, and a reduction section 30c part on the base layer 10. It may be a combined part.

On the other hand, the second cut-out line 40 is a cut-off line formed to prevent stress from being concentrated at one point or a part when the attachment part 11 and the attachment sheet 13 form a predetermined angle and a tensile force is applied. Specifically, the second incision line 40 extends on both sides of the first incision line 30 in a direction away from each other, respectively. At this time, the effect of preventing stress concentration by the second incision line 40 will be described in detail later with reference to FIGS. 5 to 7 .

Specifically, the second incision line 40 may be formed to form a gentle curve to prevent stress from being concentrated in a portion of the base layer 10 . In addition, the second incision line 40 may be symmetrically configured on the base layer 10 . Hereinafter, for convenience of description, the incision line connected to the 1A incision line 31 among the second incision lines 40 is referred to as the 2A incision line 41 , and the 1B incision line among the second incision lines 40 . The incision line following (33) is referred to as the 2B incision line (43).

Meanwhile, when the second cut-out line 40 is divided into sections, the second cut-out line 40 may specifically include a first section 40a, a second section 40b, and a third section 40c.

First, the first section 40a is a section that is connected to the first cut-out line 30 and forms a curve toward the outside of the base layer 10 . Specifically, the first section 40a of the 2A cut-out line 41 is curved toward the left end of the base layer 10, and the first section 40a of the 2B cut-out line 43 is on the right side of the base layer. The width of the portion where the attachment portion 11 is connected to the base layer 10 increases by forming a curve toward the end.

The second section 40b is a point at which a curve is drawn from the end of the first section 40a to a point forming a predetermined angle. Specifically, the 2A incision line 41 and the 2B incision line 43 are closer to the rear end (B direction) of the base layer than the ends of the 1A incision line 31 and the 1B incision line 33, respectively. It can be continued by drawing a curve toward a predetermined point on (10). In addition, at this time, the 2A incision line 41 and the 2B incision line 43 may be formed to increase the width of the left-right symmetry point.

The third section 40c is a section forming a straight line by a predetermined length toward the rear end (B direction) of the base layer 10 in the second section 40b. In this case, the third section 40c may be formed such that portions corresponding to the third section 40c in the 2A cut-out line 41 and the 2B cut-out line 43 are parallel.

On the other hand, the distance (hereinafter, the first interval; D1) between the third section 40c and the end of the base layer 10 may be set to be greater than or equal to a predetermined length in consideration of stress concentration when the adhesive sheet 1 is used. have. For example, the first interval D1 may be set to have a length longer than a straight distance (hereinafter, second interval; D2) between the third section 40c and the first incision line 30 . Details on this will be described later.

<Non-adhesive area>

Subsequently, referring to FIG. 2 , a plurality of non-adhesive regions may be formed on the back surface of the pressure-sensitive adhesive sheet 1 according to an embodiment of the present invention. Here, the non-adhesive region may mean a region in which the adhesive layer 20 is not provided on the back surface of the base layer 10 . That is, the portion on the back surface of the base layer 10 to which the adhesive is not applied may be a non-adhesive region.

In the above description, the non-adhesive region is a region to which the adhesive layer 20 is not applied, but is not limited thereto. For example, the non-adhesive region may be a region to which an adhesive having a lower adhesive strength than that of the adhesive layer 20 is applied. Hereinafter, it will be described that the adhesive layer 20 is not provided in the non-adhesive region for convenience of description, but is not limited thereto.

Specifically, the non-adhesive region may be divided into a first non-adhesive region 21 , a second non-adhesive region 23 , and a third non-adhesive region 25 according to a formed portion.

First, the first non-adhesive region 21 is a non-adhesive region formed in the attachment portion 11 . In the first non-adhesive region 21 , one end of the attaching part 11 does not adhere to the adherend while the attachment part 11 is attached to the surface of the adherend.

Specifically, the first non-adhesive region 21 may be formed on the rear end side (arrow B direction) of the attachment part 11 . Therefore, in a state in which the attachment part 11 is attached to the adherend, the end of the head of the attachment part 11 may not be attached to the adherend. Accordingly, when the user wants to separate the attachment portion 11 from the adherend, the user can easily separate the attachment portion 11 from the adherend by holding the portion of the first non-adhesive region 21 .

Meanwhile, the second non-adhesive region 23 is a non-adhesive region formed on the outer side of the base layer 10 . Here, the second non-adhesive area 23 may be a non-adhesive area provided so that the user can easily detach the pressure-sensitive adhesive sheet 1 adhered on one surface (hereinafter, referred to as the attachment surface) of the external structure to which the skin is attached.

Specifically, the second non-adhesive region 23 may be formed on the front end side (arrow H direction) of the base layer 10 . This induces the adhesive sheet 1 to be separated from the front (H direction) portion when the user separates the adhesive sheet 1 from the attachment surface.

In order to help understanding, in the following, when the direction from the base layer 10 to the adhesive layer 20 is called downward and the reverse direction is called upward, the user lifts the second non-adhesive region 23 upward to the adhesive sheet. (1) is assumed to be detached from the attachment surface. At this time, the separation of the adhesive sheet 1 from the front (H direction) portion and the separation from the rear (B direction) portion may have the following differences.

First, when the adhesive sheet 1 is separated from the attachment surface from the front, the portion where the attachment part 11 and the attachment sheet 13 are connected is the attachment part 11 and the attachment sheet 13 is the first cut-out line 30 ) will separate from the attachment surface before the parts not connected by Therefore, the adhesive sheet 1 is detached from the attachment surface, and both the attachment part 11 and the attachment sheet 13 are detachably detached.

On the other hand, when the adhesive sheet 1 is separated from the attachment surface from the rear, the portion where the attachment part 11 and the attachment sheet 13 are not connected is first separated from the attachment surface, and the attachment part 11 is still attached to the attachment surface. may remain attached to the For this reason, in order for the user to completely separate the adhesive sheet 1 from the attachment surface, a separate external force may be applied to the attachment part 11 to separate it from the attachment surface. Also, in this case, in the process of detaching the adhesive sheet 1 from the attachment surface, the attachment part 11 maintains the adhesive state, whereas the adhesive sheet 1 is separated from the attachment surface and ends at the end of the first incision line 30 . The stress is concentrated on the pressure-sensitive adhesive sheet 1 may be torn.

The third non-adhesive region 25 is a non-adhesive region formed in a predetermined region covering the second cut-out line 40 on the back surface of the base layer 10 . For example, the predetermined region in which the third non-adhesive region 25 is formed may be a region including the entire second cut-out line 40 therein.

Specifically, in the third non-adhesive region 25, a tensile force is applied to the attachment sheet 13 (specifically, the end of the second incision line) in a state where the attachment part 11 and the attachment sheet 13 are fixed to different external objects. It may be a non-adhesive area provided to prevent concentration. Here, the tensile force is an external force that separates the attachment part 11 from the surface of the base layer and the adhesive force of the adhesive sheet 1 , and the attachment part 11 and the attachment sheet 13 receive a force in different directions from the second It may be a tensile force applied to the end of the incision line (40).

If there is no third non-adhesive area 25, the attachment part 11 and the attachment sheet 13 may receive external force in different directions, and stress may be concentrated at the end of the second cut-out line 40. In this case, the end of the second incision line 40 may be further cut by an external force to damage the adhesive sheet 1 .

Conversely, when the third non-adhesive region 25 is present, when an external force is applied to the attachment portion 11 and the attachment sheet 13 , the third non-adhesive region 25 in the base layer 10 becomes the attachment portion 11 . ) or is moved along the attachment sheet 13 so that the stress is not concentrated on one point of the attachment sheet 13 .

<Stress distribution structure>

Hereinafter, a structure for dispersing the stress of the pressure-sensitive adhesive sheet 1 according to an embodiment of the present invention will be described based on FIGS. 3 to 7 .

First, Figure 3 is a view showing the state according to the use state of the adhesive sheet according to an embodiment of the present invention. In addition, FIG. 4 is a view illustrating that the wet tissue case is fixed to an external object using an adhesive sheet according to an embodiment of the present invention.

Referring to FIG. 3 , when the adhesive sheet 1 according to an embodiment of the present invention is used, the attachment part 11 is attached to an external object in a state detached from the surface of the base layer 10 , The sheet 13 may be attached to an external object different from the attachment part 11 . In this state, the adhesive sheet 1 according to an embodiment of the present invention fixes two different external objects based on the adhesive force of the adhesive layer 20 .

For example, referring to FIG. 4 , the user attaches the attachment part 11 to the wet tissue case (P) and attaches the attachment sheet 13 to the external object to fix the wet tissue case (P) to the external object. can In this case, the external object may be selected according to the user's needs. For example, the external object may be selected from a desk, floor, wall or other structure.

Meanwhile, in FIG. 4 , it is illustrated that the attachment part 11 is attached to the wet tissue case P and the attachment sheet 13 is attached to an external object, but is not limited thereto. For example, it does not matter if the attachment part 11 is attached to an external object and the attachment sheet 13 is attached to the wet tissue case P, on the contrary. Hereinafter, for convenience of description, it is assumed that the attachment part 11 is attached to the wet tissue case P and the attachment sheet 13 is attached to an external object (not shown).

In addition, in FIG. 4, an example of fixing the wet tissue case P using the adhesive sheet 1 is exemplified, but the present invention is not limited thereto. can be used for

Meanwhile, FIGS. 5 to 7 are views showing a portion for dispersing stress in the pressure-sensitive adhesive sheet 1 according to an embodiment of the present invention.

5 to 7 show a portion for dispersing stress according to the angle between the external force F acting on the attachment part 11 that fixes two external objects and the surface of the attachment sheet 13 (or the surface of the base layer) the drawing shown.

The user pulls the to-be-drawn object W from the case P at various angles in a state in which the attachment part 11 is attached to the wet tissue case P and the attachment sheet 13 is attached to an external object (not shown). can be pulled out

At this time, an external force directed upward is necessarily applied, but an external force directed to the side (by a force pulling the object to be drawn out in the side direction) may optionally also be generated. Even in this case, the adhesive sheet 1 according to an embodiment of the present invention provides a fixing force for fixing the case P and should not be damaged.

Hereinafter, a case in which the user pulls the to-be-drawn object W at various angles and finally the pressure-sensitive adhesive sheet 1 is subjected to external forces of various angles will be described as an example. For example, the external force of various angles may be an external force applied to the attachment part 11 in a state where the attachment part 11 and the attachment sheet 13 form an acute angle, a right angle, or an obtuse angle.

On the other hand, since the case P is seated on an external object, there is little risk of damage to the adhesive sheet 1 even if a separate compressive force is applied. Therefore, hereinafter, the stress distribution in the region where the second cut-out line 40 is formed to prevent damage due to tensile force will be described in detail.

First, FIG. 5 is a diagram illustrating a portion in which stress applied to an attachment portion is dispersed when an external force and the surface of the attachment sheet form an acute angle. As shown in FIG. 5 , when the attachment portion 11 and the external force F form an acute angle, stress may be dispersed at a portion where the attachment portion 11 and the attachment sheet 13 are connected.

Specifically, the width of the portion where the attachment portion 11 and the attachment sheet 13 are connected by the second cut-out line 40 is increased, so that stress distribution may be more efficient. This may be an effect obtained by cutting the base layer 10 along the first section 40a.

Meanwhile, FIG. 6 is a view showing a portion in which the stress applied to the attachment portion is dispersed when the surface of the attachment sheet forms a right angle with the external force. As shown in FIG. 6 , when the attachment portion 11 and the external force F form a right angle, the portion adjacent to the second section 40b and the third section 40c in the attachment sheet 13 is subjected to an external force ( It rises in the direction F) and disperses the stress. This is because the base layer 10 of the second cut-out line 40 is not attached to the external structure by the third non-adhesive region 25 .

Meanwhile, FIG. 7 is a diagram illustrating a portion in which the stress applied to the attachment portion is dispersed when an external force and the surface of the attachment sheet form an obtuse angle. As shown in FIG. 7 , when the attachment portion 11 and the external force F form an obtuse angle, the portion adjacent to the second section 40b and the third section 40c of the attachment sheet 13 is the external force F ) to dissipate the stress.

On the other hand, when explaining the reason why a predetermined length is required for the above-described first interval (D1), when the first interval (D1) is shorter than a predetermined length, the second cut-out line 40 in the adhesive sheet 1 and This is because the portion located between the ends may be torn due to the concentration of stress by the external force F that draws out the to-be-drawn object. In this case, when the first interval D1 is longer than necessary, there may be a disadvantage in terms of material cost. Accordingly, the first gap D1 may be formed to have a length equal to, similar to, or longer than that of the second gap D2 in consideration of stress concentration and material cost.

On the other hand, the attachment portion 11 according to an embodiment of the present invention forms a neck-head structure having a section in which the width increases with respect to the portion connected to the attachment sheet 13 , which may be for the following reasons.

Specifically, when the shape of the attachment part 11 is a straight shape without a change in width, the width of the attachment part 11 has to be relatively narrow in order to maintain the first interval D1 to a predetermined length or more. . In this case, as the width of the attachment portion 11 decreases, the force for fixing the external structure may be reduced. In addition, when the width of the attachment portion is formed to be wider in order to increase the adhesion force of the attachment portion 11 , there may be a disadvantage in terms of material cost. In addition, in consideration of the material cost, the width of the attachment part 11 is increased, but when the width of the adhesive sheet 1 is left as it is, the first interval D1 is shortened, so that the adhesive sheet 1 is torn in the process of use for the above-mentioned reasons. can get

<How to use>

8 to 9 are views showing an example of the use of the adhesive sheet 1 according to an embodiment of the present invention.

First, FIG. 8 is a diagram illustrating that a user draws out a wet tissue from a wet tissue case fixed to an adhesive sheet according to an embodiment of the present invention. As shown in FIG. 8 , the adhesive sheet 1 according to an embodiment of the present invention provides a fixing force to the wet tissue case P based on the adhesive force in the process of drawing out the wet tissue W by the user. For this reason, the wet tissue case (P) may not be pulled in the withdrawal direction together with the wet tissue (W) by the force (F) to withdraw the wet tissue (W).

In more detail, the wet tissue case (P) is raised in the direction of the external force by the force (F) to withdraw the wet tissue so that the wet tissue case (P) and the external object are in a non-contact state (refer to the arrow in FIG. 8), and in this state, the user Keep pulling the wet tissue (W) to take it out. At this time, a stress is applied to the pressure-sensitive adhesive sheet 1 by the user pulling the wet tissue (W) (F). On the other hand, as described above, this stress may be dispersed in a predetermined portion on the surface of the adhesive sheet 1 according to the force F and the angle of the adhesive sheet 1 .

Meanwhile, FIG. 9 is a view showing a wet tissue case to which an adhesive sheet is attached according to an embodiment of the present invention. As shown in FIG. 9 , the adhesive sheet 1 according to an embodiment of the present invention may be provided to the consumer in a state of being attached to the cover (C) portion of the wet tissue case (P). For example, the adhesive sheet 1 may be marketed by being attached to the cover C with the supplier's trademark printed on one surface. For this reason, in the adhesive sheet 1 according to an embodiment of the present invention, the adhesive sheet 1 and the wet tissue case P are inevitably separated in the process of using the adhesive sheet 1, so that the adhesive sheet 1 and the There is an effect of inducing separation of the wet tissue case (P).
