Description

  The present invention relates to a fastening tape used for putting a disposable diaper into a worn state, a disposable diaper using the fastening tape, and a method for producing the disposable diaper.

  Disposable diapers are broadly divided into flat diapers that can be worn with the left and right wings of the dorsal side bound to the abdomen when used, and pants-shaped diapers that are shaped like pants. Type diapers are preferred for infants and those who cannot sit on a bed or futon because the diapers can be easily replaced by removing the left and right wings even when the wearer is lying down. ing.

  As a deployable diaper, a fastening tape is provided on each of the left and right wings, and a hook-shaped engagement member (fastening portion) provided on the skin side surface of the fastening tape is formed on the anti-skin side surface of the ventral side portion. In general, it is configured to be engaged with a loop-type engaging member or the like (target part) that is worn, and in this case, it is possible to wear it tightly by engaging it widely in the vertical direction. Generally, two are arranged side by side in the direction (body height direction) (conventional example [1]).

  By the way, as for the body shape of the wearer, in general, there is not much difference between the size around the waist and around the hip in the case of an infant, but in the case of an adult, the difference between the waist circumference and the hip circumference is large, and the degree of the difference depends on the person. There are various differences in leg swing sizes with respect to the waist and hips, so if there is only one type where the two fastening parts are aligned vertically in the vertical direction as described above, the body fits well. May create gaps and cause leakage.

Therefore, in the past, a notch was formed between the above two fastening parts, and these fastening parts were handled separately, so that the position was shifted so as not to create a gap, and stopped on the ventral side part. It has been proposed (see, for example, Patent Document 1) (conventional example [2]).
JP 2004-57541 A (for example, claims, paragraph [0022])

  If it is handled separately for each fastening part by cutting as described above, it can be fastened to fit the size of each wearer's waist, hips, leg rolls, etc., but separate fastening tapes Since the portion becomes long in a band shape, the covering property to the body is lacking in a fixed state (in a diaper wearing state), and the wearing stability may be poor.

  However, the advantage of being able to wear without creating a gap is prioritized for a person who has a large difference in leg swing size with respect to the waist and hips, and the conventional example [2] is useful. On the other hand, there is a person with a body shape that does not require cutting, and in this case, it is preferable to use the disposable diaper of the conventional example [1] type without cutting from the viewpoint of wearing stability.

  However, when using diapers for a large number of patients, such as nursing homes and hospitals, preparing diapers suitable for individual patients is a cumbersome task. For this reason, a person having a body shape that does not need the above-mentioned notch for this purpose would use the conventional type [2] diaper having the notch.

  On the other hand, the manufacturing process of the diaper of the type of the conventional example [2] will be described. The fastening tape is manufactured by flowing in the longitudinal direction while applying tension to the long raw material. Since the cut is made in the direction perpendicular to the direction or in the oblique direction, the tension in the production flow direction cannot be applied widely against the raw material, and it is applied only to a small part where there is no cut. In addition, there is a problem in that it is easy to cause breakage, and it is easy to bend the cut portion, and it is difficult to position the attachment portion when attaching to the diaper body.

  In the above cited reference 1, this problem is solved by the procedure of attaching to the diaper main body before incising the fastening tape and then incising, but assembling each part of the diaper like this In the case of a method of performing processing after a long time, the production line is lengthened. Therefore, a method of assembling after making each part as a finished product (or as close to the finished product as possible) is desired.

  Therefore, the object of the present invention is a single-use disposable diaper that can be suitably used for wearers of various body shapes, and a fastening tape and a disposable diaper that are less likely to break or bend the fastening tape in the manufacturing process. An object of the present invention is to provide a method for producing this disposable diaper.

  The fastening tape according to the present invention is attached to the back side or the abdomen side of a disposable diaper, and is provided with a plurality of fastening parts (hereinafter referred to as a wearing fastening part) that are separated in the vertical direction on the side opposite to the mounting side. A plurality of fastening portions, and at least two easy incision lines extending in the direction of the attachment side are formed in parallel between the plurality of fastening portions. A notch (hereinafter also referred to as a tip notch) is formed continuously at the opposite end of the line, and the easy incision line is separated and the plurality of fastening parts are constrained. It is characterized by being relaxed.

  The disposable diaper according to the present invention is characterized in that the fastening tape is a pair of left and right provided on the back side or the abdomen side of the diaper.

  As described above, in the fastening tape and disposable diaper of the present invention, as an unused product, the easy incision line is not cut, and the user can cut it if necessary, so cutting is unnecessary. For wearers with various body shapes, the easy incision line can be used in a connected state, so that there is a sense of wearing stability and the gap can be worn without any gaps. Thus, the restraint between the wearing fastening portions is relaxed, and the individual wearing fastening portions can be fastened separately at desired positions, and thus can be worn without forming a gap.

  Moreover, the fastening tape and the disposable diaper of the present invention are easy to cut the easy incision line as described below. In other words, when there is one easy incision line, it is necessary to grip one wear fastening part side and the other wear fastening part side and to separate them in the opposite directions when cutting. It tends to be complicated. However, in this respect, in the present invention, the plurality of easy incision lines can be cut at the same time and the restraint between the plurality of wearing fastening portions can be eased by simply picking and peeling between the leading end incisions. It becomes. For example, if a diaper is worn with the easy incision line connected, and there is a gap depending on the body shape, the tip is cut in this wearing state, that is, without removing the wearing fastening part of the fastening tape from the diaper body. The wearing operation can be carried out by the procedure of picking up and tearing it off, and reattaching the wearing fastening portion causing the gap.

  In addition, since the fastening tape is not largely cut as in the conventional example [2], in the production process of the fastening tape, the tension in the production flow direction is in a wide range with respect to the material material (on the opposite side). It can be applied to a wide range from the location excluding the front end notch to the mounting side, so that the original fabric can be stably driven, and the fastening tape can be prevented from being bent or damaged. In addition, since the planar shape can be stably maintained as described above when attaching to the diaper main body, the attachment location can be easily positioned. As a result, the fastening tape can be attached to the diaper main body at the stage where the fastening tape is brought close to the finished product (or the stage where the finished product is made), and the production line can be made compact.

  In other words, as a method for producing disposable diapers, a production line for the diaper main body and a production line for the fastening tape are separated from each other, the fastening tape is produced on the fastening tape production line, and this is attached to the diaper main body. Can be adopted.

  The cutting strength of the easy incision line should be such that it can be easily cut by hand and can resist the tension applied at the time of manufacture without breaking.

  As an aspect of the said easy incision line, what formed the cut in the broken line shape is mentioned. Examples of the broken line-like cut (perforated line) include those in which the cut is dotted, those in which the length of the cut is not uniform (for example, those formed in a chain line), and the like.

  As a method of forming this broken line-shaped cut, for example, a method of pressing and cutting the fastening tape base material using a drum cutter having a broken line (dot-shaped) blade, or a method of melting and cutting by heating to a dot shape Is mentioned. In these cases, by adjusting the length and pitch (or heating width and pitch) of the above blades while taking into account the strength of the fastening tape base material, the cutting strength of the easy incision line can be set appropriately (easily by hand). Can be cut and can resist the tension during manufacture).

  As another aspect of the easy incision line, the base material of the fastening tape is made of a thermoplastic resin, and the easy incision line is a solid line or a broken line by heating the base material. In which a fragile portion is formed. In this way, the substrate can be weakened to such an extent that it can be broken by hand, for example, by thinning the substrate by heating. Specifically, by applying a heat sealing device, the base material can be made brittle, and by adjusting the degree of heating and pressurization at this time, it can be easily cut by hand and manufactured. It is preferable to use an easy incision line having a strength capable of resisting the tension of time.

  By the way, as described above, at least two easy incision lines are formed between the wearing fastening part and the wearing fastening part, so that the width between these easy incision lines becomes narrow. Depending on the strength of the adhesive tape base material, there is a concern that the rear end of the easy incision line (the end in the attachment side direction) cannot be cut and may be cut off in the middle.

  Therefore, in the present invention, it is preferable that a reinforcing material is disposed in a region sandwiched between the at least two easy incision lines so that the portion between the easy incision lines is not easily broken. In addition, by arranging the reinforcing material in this way, it becomes easy for the user to recognize the portion between the easy incision lines. It becomes easy to understand. Furthermore, if the reinforcing material is colored, the presence or absence of the reinforcing material can be recognized not only as a difference due to the texture but also as a difference in color tone, which makes it easier to understand.

  In addition, it is preferable that an auxiliary fastening portion (hereinafter sometimes referred to as an auxiliary fastening portion) is provided in a region sandwiched between the at least two easy incision lines.

  The reason for this is that, in the case where a plurality of wearing fastening parts are separately pulled and fastened by cutting along the easy incision line, depending on how the fastening position is shifted, the cutting base of the easy incision line (see above) There is a concern that the fastening tape may be peeled off due to floating or the like that rubs against clothing. When the easy incision line is cut, the portion between the easy incision lines flickers like a tail. However, if an auxiliary fastening portion is provided as described above, the floating can be suppressed, and the portion between the tail-like easy incision lines can be stopped, so there is almost no fear that the fastening tape will be peeled off by being caught, The fit of the diaper can be further improved, and the appearance is also cleaner. However, the problem of flickering between the easy incision lines is easily separated by a break-away line (like the easy incision line, etc.) so that the easy incision lines are bridged between the rear ends of the easy incision lines. A linear portion) may be formed, and the portion between the easy incision lines may be cut off.

  In addition, the presence of the auxiliary fastening portion can improve the strength of the portion between the easy incision lines as in the case where the reinforcing material is disposed, and the user can easily recognize the portion between the easy incision lines. .

  According to the fastening tape and the disposable diaper according to the present invention, it is possible to select whether to cut the easy incision line of the fastening tape at the time of wearing or not, so that it is possible to wear various body shapes without preparing various kinds of diapers. On the other hand, while being able to wear without producing the gap | clearance which causes a leak, a comfortable wearing feeling for each wearer is realizable. And since it can be applied well to wearers of various body shapes with one product like this, even if it is a case where many wearers are targeted, such as hospitals and care facilities, the types of disposable diapers to be prepared It can be reduced, the work is not complicated, and the burden on the caregiver is reduced.

  In addition, as a manufacturing method of the disposable diaper, it is possible to select a technique for incorporating the fastening tape close to the finished product and then incorporating the fastening tape into the diaper body, so that the manufacturing line can be made compact.
