Abstract

The present invention relates to a disposable diaper,

In a disposable diaper composed of a liquid permeable topsheet, a liquid impermeable backsheet, an absorber, a frontal tape, a release tape, a pason tape, etc., the panson tape may be removed from the frontal tape and the back flap liquid fired at the waist. The invention is characterized in that the new tape is attached to the transparent backsheet surface so as to remove or attach the parson tape to the new tape.

Description

Disposable diapers

The present invention relates to a fastening means of a disposable diaper, and more particularly, in a disposable diaper composed of a liquid permeable top sheet, a liquid impermeable back sheet, an absorbent body, an adhesive tape, and the like, the diaper is easily filled or pulled back while the wearer is pressed back. It relates to a disposable diaper having a fixed fastening means.

In the present invention, the disposable diaper is based on the liquid permeable topsheet 1 which is in direct contact with the skin of the wearer when worn, the liquid impermeable backsheet 2 which forms the outer surface when worn, and an absorber located therebetween. In addition, it refers to a disposable hygiene product having a function of absorbing or blocking urine and incidence excreted by a physiological action of a person by applying an elastic body and an adhesive tape as a means of improving fit and fastening.

The tape used as the double fastening means is largely attached to the frontal tape 6 attached to the front portion of the liquid impervious back sheet 2, and to the rear flap 5 at the waist portion so that the frontal tape 6 and the ash are It can be divided into adhesive tape (7), and release tape (8) for fixing the pason tape before wearing.

In addition, they can be divided into various types according to the application method. The typical tapes with adhesive coating on the backing are composed of mechanical tapes such as hooks & loops and release, pattern and frontal tapes. Prelaminated tape.

However, the conventional fastening means may be easy to fill the diaper while the wearer is lying on the back, but when it is in the back state, it is inconvenient to remove the panson tape adhered to the frontal tape. The emergence of disposable diapers having a structure that can be fastened has been urgently needed.

Accordingly, an object of the present invention is to provide a diaper that can easily hold the fastened tape even when pressed backward by adding another new tape in addition to the existing tape so that the tape can be pulled back and forth according to the user's convenience. .

Hereinafter, the accompanying drawings of the present invention will be described in detail.

In FIG. 1, the disposable diaper according to the present invention is viewed from the liquid impermeable back sheet 2 side, and a new tape 9 is attached to the liquid impermeable back sheet surface outside the front flap 4 of the waist and the pason is placed thereon. It is a top view of what stuck the tape 7.

FIG. 2 is an illustration (arrow symbol) showing that the disposable diaper according to the present invention can be removed or pasted by the user in a cold state in accordance with a posture in an easy direction. In other words, the taper tape 7 is removed from the rear flap of the liquid permeable back sheet 2 and attached to the frontal tape 6. In this case, when the diaper is to be removed from the user, the diaper is not only from the front but also from the rear flap. It can also be removed from the tape 9. Therefore, it is possible to easily and easily pull out the pattern tape 7 in any direction before and after.

3 is a cross-sectional view of a disposable diaper flap having a fastening means according to the present invention, unlike a conventional tape, after attaching a new tape 9 to the back flap liquid-impermeable back sheet 2 of the waist portion first, and then using a pason tape ( 7) It is attached so that it can be attached and detached.

At this time, when the diaper is filled, the adhesion between the new tape 9 attached to the rear flap of the waist and the pason tape 7 is maintained for a long time. That is, the holding force (Shear Adhesion or Holding Power) and the force that allows the user to easily fall off the Parson tape (7) from the new tape. In other words, Peel Adhision is important, and the following test was repeated to adjust the values of the holding strength and adhesive strength of the existing tape in order to select a tape having the applicable physical properties.

The measurement of the holding force was time to withstand a certain load at a constant temperature, and the measurement of the adhesive force was tested by the load applied when peeling at a 180 ° angle at a constant speed.

The final test results are as follows.

Here, the holding force was measured by the time it took to hang the weight of 1kg on the pason tape in the oven at 40 ℃, the adhesive area between the pason and the new tape was 1 inch × 1 inch, the other conditions were the same.

Adhesion was also measured by the load on the peel tape at 180 ° peeling off the release tape.

As can be seen from the experimental results, the holding force was similar or slightly higher (previously measured by the time it took for the panson tape (7) to detach from the back flap of the disposable diaper), and the peeling force was also known as the pason on the existing frontal frontal. The tape 7 was adjusted to have a value similar to or slightly higher than the peel force (experimental value: 700 gf / in).

Based on this, a hand-made product is made and described in detail by the following Examples and Comparative Examples.

Example 1,2 and Comparative Example 1,2

Example 1

With the disposable diaper according to the present invention, the new tape 9 is attached to the liquid impermeable backsheet 2 of the rear flap and the pason tape 7 is adhered thereto, but the adhesive surface of the new tape 9 and the pason tape 7 is adhered thereto. (7-Ⅱ) and (9-Ⅰ) are disposable diapers with loops and hooks, respectively.

Example 2

Disposable diapers in which the adhesive surfaces of the new tape 9 and the parson tape 7 are made of a polymer film and an adhesive, respectively, in Example 1.

Comparative Example 1

Disposable diaper with a conventional taper attached to the liquid impervious back sheet (2) on the back flap (2) and attached to the loop frontal with a hook.

Comparative Example 2

In Comparative Example 1, the panson tape and the release tape are a polymer film, and a disposable diaper under which an adhesive is formed.

Determination of ease of diaper filling

Disposable diapers prepared in the above Examples and Comparative Examples were divided into 50 50 people each for standing infants weighing more than 10 kg, and scored by scoring absolute satisfaction with 10 out of 10 points and averaged them.

(0 points: very dissatisfied ← ‥‥‥‥‥‥‥‥ → 10 points: very satisfied)

Judgment result for ease of diaper filling

Examples 1 and 2 showed a high score of 8.6 or more, while Comparative Examples 1 and 2 showed a low score of 5.0 or less.

This proves that the diaper wearer who is lying on the back has the advantage of being able to pick and use the pason from the rear flap in addition to removing the pason tape from the frontal tape when filling or removing the diaper. Doing.

1 is a plan view of a disposable diaper which can be easily filled or peeled off in a back lying state according to the present invention from the liquid-impermeable back sheet side;

2 is a side view of the disposable diaper according to the present invention, which shows that the disposable diaper which can be easily filled or peeled off in the back state can be peeled off in a desired direction according to convenience in the cold state.

3 is a cross-sectional view showing a portion of the fastening means of the disposable diaper which can be easily filled or peeled off in the back lying state according to the present invention.
