Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a post-treatment tape of a paper diaper for holding the diaper in a rolled state when discarding the diaper, and a paper diaper with a post-treatment tape having the post-treatment tape attached to the outer surface of the diaper. .
The paper diapers used in the present application include pants-type diapers and flat-type diapers (types in which left and right side portions are fastened with fastening tapes when worn).

[0002]

2. Description of the Related Art Conventionally, some paper diapers have a post-treatment tape Y attached to the outer surface 51 of the diaper as shown in FIG. By the way, as shown in FIG. 9, a conventional general post-treatment tape Y includes a first strip 1 on the base side, a second strip 2 on the intermediate side, and a third strip 3 on the front side. The first to the third are connected in sequence to one row.
The respective strips 1, 2 and 3 are folded in a Z shape and are bonded to the outer surface 51 of the disposable diaper in a position facing the waist side edge 52 in a vertically oriented posture.

That is, each of the first to third strips 1, 2, and 3 has an adhesive 11, 12, and 13 attached to one side thereof, and the end portions of the strips 1, 2, and 3 are connected to each other. A series of post-processing tapes Y are formed by sequentially adhering them, and the adhesive attachment surface (reference numeral 11) of the first strip 1 in a state where each strip 1, 2, 3 is folded in a Z shape.
Is adhered to the outer surface 51 of the diaper.

Although the strips 1, 2, 3 are actually film-shaped ultra-thin tapes (for example, vinyl tapes),
In FIGS. 9 and 10, for the sake of easy understanding, they are shown with a considerable thickness. Also, between the first strip 1 and the second strip 2,
Also, the second strip 3 and the third strip 3 are shown with a space therebetween for the sake of clarity in the drawing, but in the folded state of each strip, the second strip is actually shown. The strip 2 is adhered to the first strip 1 by the adhesive 12 on the side of the second strip 2, and the third strip 3 is attached to the second strip 2 on the side of the third strip 3 by the adhesive 1.
The second strip 3 and the third strip 3 do not flicker because they are bonded together. In addition, the portion where the ends of the strips 1, 2 and 3 are connected to each other, the adhesive on each side (11
And 12 or 12 and 13) are adhered to each other, the adhesive strength is strong, but the adhesive strength is weak in the strip portion adhered only by the adhesive on one side. In this post-processing tape Y, when the knob piece 5 at the tip of the third strip 3 is picked up and pulled outward, the third strip 3 is peeled off from the second strip 2, and then the second strip 3 2 is peeled off from the first strip 1 so that the second strip 3 and the third strip 3 extend linearly as shown in FIG. In addition, the upright point portion P where the second strip 2 stands up with respect to the first strip 1 is located at the upper (waist side edge 52 side) end of the first strip 1.

The post-processing tape Y of the paper diaper with the post-processing tape shown in FIG. 1 is used as follows. That is, at the time of discarding the paper diaper, as shown in FIG. 2, the paper diaper is rolled up so that the crotch side soiled with excrement is rolled inward, and the tip knob piece 5 of the post-processing tape Y is pulled outward, As shown in 10, the second strip 3 and the third strip 3 are linearly stretched, and the strips (2 and 3) in the stretched portion are tensioned while the adhesive-adhesive surface of the third strip 3 is stretched. The outer surface 51 of the disposable diaper, which exceeds the waist-side edge portion 52 of the rolled disposable diaper (reference numeral 13)
To adhere to. In this way, the post-processing tape Y can hold the paper diaper in a rolled state, and the dirty portion does not come into contact with the hand at the time of disposal, so that it can be treated hygienically.

[0006]

By the way, the conventional post-processing tape Y shown in FIGS.
As shown in 0, the second strip 3 and the third strip 3 are linearly extended, and when a large tension is applied to the strip of the extended portion, the tension is applied to the rising point P of the second strip 2. It concentrates in the vicinity, and the first strip 1 is easily peeled from the vicinity of the upper end 1c thereof. Particularly, when the knob piece 5 is grasped and pulled down from the state of FIG. 10, the adhesive portion of the first strip 1 to the outer surface 51 of the diaper is peeled off relatively easily from the rising point portion P (upper end portion 1c) side. I have something to do. In addition, a caregiver such as an infant may intentionally remove the knob piece 5 of the post-processing tape Y from the adhesive portion peeling direction (see FIG.
Although it is not strongly pulled downward (below 0), an infant may pull the knob piece 5 in the adhesive portion peeling direction with a sense of play. In that case, the first strip 1 is peeled off from the outer surface 51 of the disposable diaper relatively easily. Sometimes.

In view of the conventional problem that the post-treatment tape (first strip) is easily peeled off from the outer surface of the diaper as described above, the present invention prevents the post-treatment tape from being peeled off even if it is carelessly handled. An object of the present invention is to provide a post-treatment tape for a disposable diaper and a paper diaper with a post-treatment tape.

[0008]

The present invention has the following constitution as means for solving the above problems.

The Invention of Claim 1 of the Present Invention The invention of claim 1 of the present application is intended for a post-processing tape for holding the diaper in a rolled state when the diaper is discarded.

The post-processing tape according to claim 1 is
The first strip on the base side, the second strip on the intermediate side, and the third strip on the front side are connected in a Z-shape in a sequentially bendable state. A knob piece for facilitating pinching with a finger may be attached to the tip portion (free side end portion) of the third strip.

At the standing point portion where the second strip stands upright from the first strip, a reinforcing strip having a predetermined length extending in the direction opposite to the extending direction of the first strip is continuous. . That is, the first strip and the reinforcing strip are extended by a predetermined length in opposite directions on the same plane with the standing point portion interposed therebetween. In the present invention, as the reinforcing strip, a member different from the first strip and the second strip can be used. In that case, one end of the reinforcing strip is erected on the second strip. It is advisable to bond it near the dots.

Adhesives that can be adhered to the outer surface of the diaper are attached to the respective surfaces of the first strip and the reinforcing strip that are opposite to the third strip side (the side that faces the outer surface of the diaper when in use). . Further, a pressure-sensitive adhesive which can be adhered to the outer surface of the diaper is attached to the surface of the third strip facing the second strip.

The pressure-sensitive adhesive adhering surfaces of the first strip and the reinforcing strip may be covered with a peelable release sheet.

As the first to third strips, for example, a vinyl adhesive tape cut into a predetermined length can be used. In this type of adhesive tape, an adhesive is attached to the entire one surface of the tape, and the connecting portion of each of the first to third strips is
By firmly adhering the adhesive-adhesive surfaces to each other, it is possible to firmly bond them. Further, this type of adhesive tape has a certain degree of adhesive strength when the adhesive-adhesive surface is adhered to the adhesive-non-adhesive surface, but has an adhesive strength that allows relatively easy peeling.

The post-treatment tape for a disposable diaper according to claim 1 can be provided by itself or can be provided together with the disposable diaper (in an unattached state). And this post-treatment tape is used when disposing of used diapers.
It can be attached to the outer surface of the disposable diaper for use. That is, the post-treatment tape adheres the adhesive-adhesive surfaces of the first strip and the reinforcing strip to appropriate places on the outer surface of the used paper diaper (near the waist side edge portion) when the dirty paper diaper is discarded. At that time, when the second strip and the third strip are stretched, the stretch strip is attached at a position such that the predetermined length range of the stretch strip can extend beyond the waist side edge of the disposable diaper. In addition, the protruding length from the waist side edge of the extension strip is 5 mm to 120
It can be carried out in the range of mm, of which 35 mm to 60 mm
A degree is preferable. With this post-processing tape attached,
The first strip and the reinforcing strip are adhered to the outer surface of the diaper on the front and rear sides of the base end portion (upright point portion) of the second strip.

Then, the dirty paper diaper is rolled up from the crotch portion side, and the tip end (free end) of the third strip is pinched to make a third
The strip and the second strip are peeled off in sequence and linearly extended,
In this state, the adhesive-adhesive surface of the third strip is adhered to the outer surface of the diaper beyond the waist side edge. Then, the used disposable diaper can be maintained in a rolled state, and can be easily discarded.

During the extension work of the third strip and the second strip,
Also, when pulling the adhesive portion of the outer surface of the diaper with the extension strip (tightening the paper diaper) or the like, a considerable amount of pulling force is concentrated on the erected points of the second strip, but the erected points are on both sides. In, the first strip and the reinforcing strip are bonded to the outer surface of the diaper, so that the adhesive force between the two strips increases the holding force with respect to the standing point. Further, since both of the strips hold the upright portions from both sides, even if the pulling direction with respect to the upright portions is biased (whether pulling from above or below), either strip (opposite to the pulling direction) Since the holding force of the strip on the side is maintained in a strong state, it is possible to prevent the strip on the weak side (the side where peeling is easy) from peeling.

Invention of Claim 2 The invention of Claim 2 of the present application is the post-processing tape of Claim 1 wherein the length L ₁ from the rising point of the second strip to the end on the side of the first strip. , The length L ₂ from the standing point to the end on the side of the reinforcing strip is set to 2 · L ₂ ≦ L ₁ ≦ 3 · L _2, and the length L ₂ on the side of the reinforcing strip is 15 mm to It is set in the range of 25 mm.

In the post-processing tape in which the first strip and the reinforcing strip are extended on both sides of the rising strip of the second strip, the length L ₂ from the rising strip to the end on the side of the reinforcing strip is , 15 mm
If the length is about 25 mm, the holding force (peeling resistance) is sufficient, and the length L ₁ from the standing point to the end on the first strip side is L _1.
Is set to be in the range of not less than 2 times and not more than 3 times the length L ₂ (15 mm to 25 mm), the second polymerized on the first strip.
The length of the strip can be increased, the total length (extended length) of the second strip and the third strip can be sufficiently secured, and the entire length does not become longer than necessary. For example, the length L on one side of the reinforcing strip
_{When 2} is the minimum of 15 mm, the minimum length L ₁ of the first strip side
Is 30 mm, in which case the length of the second strip is 30 mm,
The length of the third strip can be set to 45 mm (15 mm of L ₂ +30 mm of the length of the second strip), and the total effective length of the second strip and the third strip can be set to 75 mm. Further, if the length L ₂ on the side of the reinforcing strip is the maximum of 25 mm, the length L ₁ on the side of the first strip is 50 mm at the minimum and 75 mm at the maximum, and accordingly the second
The total length of the strip and the third strip is 125 mm minimum and 1 maximum.
It will be 75 mm. The total length of the second strip and the third strip is
It can be carried out in the range of 75 mm to 175 mm, but is preferably 75 mm to 125 mm.

By the way, when this kind of post-treatment tape is attached to the waist side edge of the disposable diaper, the waist side edge has a shirring portion (expandable portion) having a width of about 30 mm to 50 mm. The post-treatment tape cannot be attached to. Therefore, when the post-treatment tape is attached near the waist side edge portion, it is necessary to attach the post-treatment tape at a position reserved at least downward by the width of the shirring portion. On the other hand, when the second strip and the third strip are stretched, the protruding length from the waist side edge of the stretched strip is 5 mm as described above.
It can be carried out in a range of up to 120 mm (among them, preferably 35 mm to 60 mm). Then, from such conditions, the extension length when the second strip and the third strip are extended (the length from the rising point of the second strip to the tip of the third strip) is 75 mm to 175 mm (preferably 75 mm to 125
mm), but the above condition (2 · L ₂ ≦ L ₁ ≦ 3 · L ₂ and the length L ₂ = 15 mm to 25 m in claim 2 of the present application.
In m), the extension length of each strip can be set within 75 mm to 175 mm.

Invention of Claim 3 of the Invention In the invention of Claim 3 of the present invention, in the post-treatment tape of Claim 1 or 2, the reinforcing strip is formed by extending the second strip. In this case, the reinforcing strip is continuous with the second strip.

Invention of Claim 4 of the Invention According to the invention of Claim 4 of the present application, in the post-treatment tape of Claim 1 or 2, the reinforcing strip is an extension of the first strip. In this case, the reinforcing strip is integrally continuous with the first strip.

The Invention of Claim 5 of the Present Invention The invention of claim 5 of the present application is directed to a paper diaper with a post-processing tape to which a post-processing tape for holding the paper diaper in a rolled state at the time of discarding the paper diaper is attached.

According to the paper diaper with a post-treatment tape of the invention of claim 5, the post-treatment tape of claim 1 is used, and the first strip and the reinforcing strip of the post-treatment tape are attached to the waist side of the outer surface of the diaper. Adhesives are attached to the outer surface of the disposable diaper in a posture in which they are vertically oriented at the edge position.

In this way, if the post-treatment tape is adhered to the outer surface of the disposable diaper in advance, the third tape is immediately applied after the disposable diaper is used.
The strip and the second strip can be extended and used.

Further, in the post-processing tape used in claim 5, both sides of the rising point portion of the second strip are adhered to the outer surface of the diaper with the first strip and the reinforcing strip. Similar to the description in 1, the post-processing tape can be firmly held against the outer surface of the diaper.

The invention of claim 6 of the present application is the invention of claim 6 of the application, wherein the paper diaper with the post-processing tape of claim 5 is used as the post-processing tape.
I'm using one.

That is, according to claim 6, the post-processing tape has a length L ₁ from the rising point of the second strip to the end on the side of the first strip and the end on the side of the reinforcing strip from the rising point. While setting the relationship with the length up to 2 · L ₂ ≦ L ₁ ≦ 3 · L ₂ ,
Length from the standing point to the end on the side of the reinforcing strip Length L ₂ is 1
It is used in the range of 5 mm to 25 mm.

The post-processing tape is composed of the third strip and the second strip.
The length from the standing point when the strip is linearly extended to the tip of the third strip is measured from the attachment position of the rising point of the post-treatment tape attached to the paper diaper to the waist side edge portion. 5mm ~ 120mm (preferably 35mm ~) from the length to the edge
It is set to be 60 mm) longer.

Therefore, in the paper diaper with the post-treatment tape according to claim 6, as in the case of claim 2, the adhesion range (length L ₂ = 15 mm to 25 mm) of the reinforcing strip portion can be sufficiently secured, and The total extension length of the second strip and the third strip can be sufficiently secured (for example, the total extension length is 75 mm to 175 mm).
In addition, it is possible to sufficiently secure the length of the extension strips (the second strip and the third strip) protruding from the waist side edge portion.

In the first embodiment, the second strip 2 is integrally formed with a reinforcement strip 4 which will be described later.

Each of the first to third strips 1, 2 and 3 is made of, for example, a vinyl adhesive tape cut into a predetermined length. The width of each strip 1, 2, 3 is 15 mm
It is a degree. In each of the first to third strips 1, 2, and 3,
Adhesives 11, 12, and 13 are attached to the entire one surface of each. In this type of pressure-sensitive adhesive tape, when the pressure-sensitive adhesive adhered surfaces are adhered to each other, both are strongly adhered, but when the pressure-sensitive adhesive adhered surface is adhered to the non-adhesive surface, it has a certain degree of holding power. The adhesive strength is such that it can be peeled off relatively easily.

The material length of the first strip 1 is about 54 mm,
At the left end of the first strip 1, a folded-back portion 1b is formed which is folded back upward by a predetermined small length (for example, about 8 mm) with the adhesive surface of the adhesive 11 facing outward. The adhesive 11 is also attached to the upper surface of the folded portion 1b.

The material length of the second strip 2 is about 66 mm,
At the right end portion of the second strip 2, a folded-back portion 2b is formed by folding back the adhesive 12 to the upper side by a predetermined small length (for example, about 10 mm) with the surface on which the adhesive 12 is attached facing outward. The adhesive 12 is also attached to the upper surface of the folded portion 2b. still,
In FIG. 3 and FIG. 4, a stepped portion is shown in the middle portion of the second strip 2 (a connection portion with the first strip 1) for drawing, but in reality, the first strip 1 is a pole. Since it is thin, the second strip 2 has a flat shape as a whole.

The material length of the third strip 3 is about 54 mm.
The material length of the knob piece 5 is about 9 mm. It should be noted that this knob piece 5 may be of a different color so that it can be distinguished from the other strips 1, 2, 3.

The left end portion (folded portion 1b) of the first strip 1 is
It is connected to the lower surface of the middle part of the second strip 2 on the left side. That is, the first strip 1 and the second strip 2 are adhered to the lower surface of the left end of the second strip 2 in the range of the folded portion 1b at the left end of the first strip 1 with the adhesives 11 and 12. By doing so, they are firmly connected. The second strip 2 can be bent and extended with respect to the first strip 1 at the connecting portion. The bending point of the second strip 2 with respect to the first strip 1 is the standing point P of the second strip 2.

On the left side of the standing point P (on the side opposite to the first strip 1), the reinforcing strip 4 is continuous. In the first embodiment, the reinforcing strip 4 is formed by extending the second strip 2.

In the third embodiment of the paper diaper with post-processing tape shown in FIG. 6, the post-processing tape Y (with the release sheet 6 peeled off) is directed in the vertical direction to the outer surface 5 of the diaper.
It is attached at a position close to the waist side edge portion 52 in FIG. When the post-processing tape Y is attached, the adhesive adhesive surfaces (reference numerals 11 and 14) of the reinforcing strip 4 and the first strip 1 are adhered to the outer surface 51 of the diaper, respectively. The first strip 1 and the second strip 2 are located above and below the rising point P of the strip 2.

By the way, in the underpants-type disposable diaper 50 shown in FIGS. 1 and 6 to 8, the width M ₁ is set at the waist side edge portion 52.
Shirring part (expansion / contraction part) 53 (M ₁ = about 30 mm)
However, the reinforcing strip 4 and the first strip 1 of the post-processing tape Y cannot be bonded thereto. Therefore, when the post-processing tape is attached to the position close to the waist-side edge portion 52, it is necessary to attach the post-treatment tape at a position with the width M ₁ of the shirring portion 53 down. Then, the third of FIGS.
In the embodiment, the upper end of the post-treatment tape Y (the end 4a of the reinforcing strip 4) is extended from the waist side edge 52 to the length M ₂ (M ₂ = 40).
(around mm) so that it is installed downward. Further, in this state, the rising point portion P of the second strip 2 from the waist side edge portion 52.
The length M _{3 up to} is about 56 mm.

On the other hand, the second strip 2 and the third strip 2 of the post-processing tape Y
The strip 3 is linearly stretched as shown in FIG. 8, and the length L ₅ (L ₃ + L _{4 of} FIG. 7) of the stretched strip is 94 m.
It will be about m. Therefore, in the paper diaper with the post-treatment tape of the third embodiment, the length L ₅ (94 mm) of the extension strip when the second strip 3 and the third strip 3 are linearly extended.
However, it is about 38 mm longer than the length M ₃ (56 mm) from the waist edge 52 to the standing point P of the second strip 2. Difference between this length L ₅ (94 mm) and length M ₃ (56 mm) (38 mm)
Is the length protruding from the waist-side edge portion 52 when holding a rolled-up diaper as shown in FIG. 2 (adhesion margin). In addition, the protruding length (38 mm) of the extension strip in the case of the waist side edge portion 52 is within the preferable range of "35 mm to 60 mm" described in claim 6.

In the paper diaper with the post-treatment tape of the third embodiment, the reinforcing strip 4 and the first strip 1 are provided on the upper and lower sides of the rising point P of the second strip 2 by the adhesives 14 and 11, respectively. It is adhered to the outer surface 51 of the disposable diaper.

When the used paper diaper (FIG. 1) is discarded, the paper diaper 50 is rolled up from the crotch portion side as shown in FIG. 2, and the knob piece 5 is picked up to pull out the third strip 3 and the second strip 2. Are sequentially peeled off and linearly extended, and in that state, the adhesive-adhesive surface of the third strip 3 is bonded to the outer surface 51 of the diaper beyond the waist-side edge portion 52.

By the way, when the third strip 3 and the second strip 2 are stretched and when the stretched strip pulls the adhesive part of the outer surface of the diaper (tighten the diaper), the second strip 2 is pulled. Although a considerable amount of tensile force is concentrated on the rising point portion P of the above, since the reinforcing strip 4 and the first strip 1 are bonded to the outer surface 51 of the diaper above and below the rising point P,
The holding force with respect to the standing point P is increased by the adhesive force of the two strips 1 and 4. Further, since both the strips 1 and 4 hold the upright point portion P from both sides, even if the pulling direction with respect to the upright point portion P is biased (whether it is pulled from above or below), either strip Since the holding force of (the strip on the side opposite to the pulling direction) is maintained in a strong state, the strip on the weak side does not receive the peeling action.

In this post-processing tape Y, the second strip 2
L from the upstanding point P to the end 1a on the first strip 1 side
_1, the relationship between the length L ₂ from the standing point portion P to the end portion 4a of the reinforcing strips 4 side, and sets to _{2 · L 2 ≦ L 1 ≦} 3 · L 2, the reinforcing strip 4 side The length L ₂ of each of the reinforcing strips is set in the range of 15 mm to 25 mm. By doing so, the holding force of the reinforcing strip 4 can be sufficiently secured, and at the same time, the length L ₅ of the extension strip during use can be increased. (The total effective length of the second strip 3 and the third strip 3) can be sufficiently secured.
