Description

[Detailed description of the invention] Γ Industrial application field The present invention relates to improvement of disposable diapers.

Γ Conventional technology Traditionally, this type of disposable diaper
For example, diapers are known in which a water-absorbing layer such as paper cotton is laminated on a water-impermeable synthetic resin film such as polyethylene, and this water-absorbing layer is covered with a non-woven fabric. If you do so, you will need to secure the disposable diaper around your waist.

As such a fixing means, a band piece is integrally attached to the disposable diaper, but the base of the band piece is connected to the upper end of both side edges of the paper diaper, and the tip side is attached in a state where it can be freely expanded. Therefore, when stacking a large number of disposable diapers after manufacturing, it becomes necessary to fold the left and right band pieces over the top of the disposable diaper one by one, which not only requires considerable time and effort for packaging, but also makes it difficult to display and sell the products. When handled, the band pieces moved unnecessarily, causing them to lose their shape, resulting in poor appearance.

For this reason, as described in Japanese Patent Application Laid-open No. 48-49542, the left and right band pieces are overlapped on the upper surface of the disposable diaper, and their opposing ends are formed integrally with each other, and a perforation is formed between the two ends. A disposable diaper was devised that was separable.

Γ Problems to be solved by the invention However, with this structure, the total length of the pair of strip fasteners (band pieces) is smaller than the width of the diaper, and when worn on the wearer's body. There is not enough space in terms of handling dimensions, and there is a risk of damage to the fastener (band piece). Also,
Since the pair of left and right hand pieces are connected through the perforations in a tensioned state, there is a problem that if the hand pieces are pulled forcibly during sales or other handling, they will separate from the perforations and the product value will decrease. , Furthermore, if the connection force through the perforation is strong,
The band piece itself may be damaged. Furthermore, during use, it is difficult to easily create a space between the band pieces and the upper surface of the disposable diaper, which are in tension with each other, so that the left and right band pieces cannot be separated manually. There were problems in that unreasonable tensile force was applied to the material and the separation work could not be carried out smoothly.

The object of the present invention is to provide a disposable diaper that eliminates these problems.

Γ Means for Solving the Problems In order to achieve the above object, the disposable diaper of the present invention has band pieces 2, 2 at the upper ends of both side edges of the main body 1 of the disposable diaper, as shown in the drawings corresponding to the embodiments. In a disposable diaper with attached ends, these band pieces 2, 2 are folded over the upper surface of the main body 1 of the disposable diaper, and one end of the attachment pieces 4, 4 made of synthetic resin film is attached to the upper surface of the tip of the band pieces 2, 2. Glue them together and attach these mounting pieces 4, 4 to the band pieces 2, 2.
It is characterized in that the upper surface of the distal end portion of the attachment piece 4 is multi-layered and folded multiple times, and the distal edges of the mounting pieces 4, 4 are integrally connected via a separated portion 3 such as a perforation.

Γ Effect The left and right band pieces 2, 2 folded over the upper surface of the disposable diaper main body 1 are connected to each other by interposing attachment pieces 4, 4 whose tips are folded multiple times to form a multilayer structure. 4 are separated from each other and unfolded, and then the wearer is fitted with the paper diaper body, and then the attachment pieces are fixed to the paper diaper body. In addition, even if a tensile force is applied to the left and right band pieces 2, 2 during the above-mentioned installation, the mounting pieces 4, 4 have sufficient length compared to conventional band pieces and can be loosened according to the tension. Therefore, no unreasonable tension is applied to the left and right band pieces 2, 2.

Furthermore, when the left and right band pieces 2, 2 are to be separated via a part to be separated 3 such as a perforation, the attachment pieces 4, 4 are expanded to separate both band pieces 2, 2 upward from the upper surface of the disposable diaper main body 1. Therefore, the two parts to be separated can be easily separated by manually picking the parts to be separated without applying an unreasonable tension force to the band pieces 2, 2.

Γ Example To explain the example of the present invention with reference to the drawings, 1
is a longitudinally rectangular paper diaper main body, and the left and right band pieces 2, 2 of a horizontally elongated rectangular shape made of a synthetic resin film such as polyethylene, nonwoven fabric, or other suitable material are attached to one end of the paper diaper main body 1 at the upper ends of both edges on the long side. It is folded over the top of the section.

Reference numerals 4 and 4 denote mounting pieces made of a synthetic resin film which are superimposed on the upper surfaces of the tip ends of the left and right band pieces 2, 2 and bonded by heat bonding or an appropriate adhesive; 4 is folded multiple times (twice) on the upper surface of the tip portions of the band pieces 2, 2 to form a multilayer (3 layers), and the tip edges of the attachment pieces 4, 4 are separated via a part to be separated 3 such as a perforation. , are expandably articulated.

As shown in FIG. 5, the part to be separated 3 may have a structure in which the upper surfaces of the mounting pieces 2, 2 are separably connected by an adhesive tape piece 3a.

Reference numerals 5 and 5 denote adhesives (hot melt) applied to the lower surfaces of the attaching pieces 4, 4 near both sides with the to-be-separated portion 3 in the center, and when worn, as shown in FIG. The paper diaper is fastened by adhering to the side edge surface of the paper diaper.

Note that these adhesives 5, 5 are attached to the left and right band pieces 2,
It may be applied to the lower surface of the tip of No. 2.

Although various structures may be adopted as the main body 1 of the disposable diaper, the one shown in the figure has a paper cotton layer or pulp mat on a water-impermeable synthetic resin film 6 of elongated and rectangular shape made of polyethylene, polyester, polypropylene, etc. Both sides of the film 6 are folded over the upper surfaces of both sides of the water absorbing layer 7, and the lower surfaces of both sides of the longitudinally rectangular nonwoven fabric 8 are bonded by thermo-pressure bonding or as appropriate on the folded upper surface. It is integrally bonded with adhesive, and furthermore, two inclined cuts 9, 9 are provided on both sides of the water absorbing layer 7, each oriented toward the center of the water absorbing layer 7, and these inclined cuts 9, 9 are formed. A longitudinal line connecting the inner ends of the fold line 10 is defined as a fold line 10, and the trapezoidal portions 7a and 7a formed by the fold line 10 and the inclined cuts 9 and 9 are fold lines 10 and 1.
By folding it over the upper surface of the water absorbing layer between 0 and 10 to increase the thickness of the water absorbing layer in this part, the water absorption and water retention properties are increased. 11 is stretched in the longitudinal direction and worn, the centers of both side edges of the paper diaper main body 1 are in close contact with the inner thighs of the body to prevent leakage.

Γ Effect of the invention As described above, according to the invention, disposable diapers are
Left and right band pieces 2 attached to the upper ends of both sides of the
2 is connected between its tips on the upper surface of the disposable diaper main body 1 via the attachment piece 4, so that it does not unexpectedly unfold outward from the disposable diaper main body 1.
Therefore, the left and right band pieces 2, 2, which are folded over the top surface of the disposable diaper main body 1, are not only easy to handle when stacking products for packaging, but also the left and right band pieces 2, 2, whose tips are folded together multiple times to form a multilayer structure. Since the pair of attachment bands 2, 2 are connected through the attached attachment pieces 4, 4, the total length of the pair of attachment bands 2, 2 is substantially extended by the length of the attachment pieces 4, 4, respectively, making it easier to wear the disposable diaper body than in the prior art. In addition, even if a tensile force is applied to the left and right band pieces 2, 2, the mounting pieces 4, 4 will loosen in response to the tension, so that the left and right band pieces 2, 2 will not be unreasonably long. Since no tension force is applied, it is possible to prevent these band pieces 2, 2 from being torn or damaged.

Moreover, when separating the left and right band pieces 2, 2 through the separation part 3 such as a perforation, the mounting pieces 4, 4 are expanded and both band pieces 2, 2 are pulled upward from the upper surface of the disposable diaper main body 1. This allows the band pieces 2, 2 to be easily separated by pinching the two parts to be separated without applying unreasonable tension to the band pieces 2, 2.

Further, the band pieces 2, 2 are disposed on the upper surface of the disposable diaper main body 1 in a state that they are integrally connected to each other, and the attachment pieces 4
Since it is in a multi-layered state, when manufacturing a disposable diaper, the attachment piece 4 and the band piece 2, which are integrated at the center via the part to be separated 3, are simply brought into close contact with each other along the upper surface of the nonwoven fabric forming the main body 1 of the disposable diaper. It can be easily manufactured by conventional manufacturing processes, and the width of the manufacturing line can be made the width of the disposable diaper main body 1, so that the floor space of manufacturing equipment can be reduced.
