Fig. 6 has broken a seal sanitary napkin in the independent bag with its plane graph of opening from folded state according to Fig. 5.

First and

second wing

23,24 of sanitary napkin in the independent bag shown in Figure 6 is in the state that is folded on the top flat 12.The rearward end 17 of sanitary towel 2 overlaps on the mid portion 18 top flat bending to the inside along chain-dotted line A-A with the arrow directions X, and the leading section 16 of sanitary towel is crooked and overlap on the rearward end 17 with arrow y direction along chain-dotted line B-B, and its state as shown in Figure 4.

The SANITARY NAPKIN CONSTRUCTION of the independent bag of band is described below in conjunction with Fig. 4.The plastic sheeting of the independent bag 3 of formation and sanitary towel 2 overlap each other and are integral, and are converted into three layers.First adhesion zone 26 in the sanitary towel 2 is by first separate paper, 31 covering protections, and second adhesion zone 27 is by second separate paper, 32 covering protections, and the 3rd adhesion zone 28 is by the 3rd separate paper 33 covering protections.First separate paper 31 is bonded on by first hot-melt adhesive 36 on the rearward end 40B inner face of independent bag 3, second separate paper 32 by second hot-melt adhesive 37 with position that first separate paper 31 overlaps each other on engage.The 3rd separate paper 33 is bonded on several positions of independent bag 3 inner faces by the 3rd hot-melt adhesive 38.Encapsulation is bonded in the independently outside of the leading section 40A of bag 3 with the base end part 4A of splicing tape 4 by the 4th bonding agent 39, is bonded in the independently outside of the rearward end 40B of bag 3 with tearable the turning up the soil of 4 free end 4B.The inner face of the independent bag at the position that free end 4B engages also is the part by the 3rd hot-melt adhesive 38 bonding the 3rd separate papers 33.Splicing tape 4 is bent to form non-cementability grip portion 4C to the inside by the fore-end of free end 4B.Can find out obviously that from Fig. 4 and Fig. 6 first separate paper 31 is in the rearward extended state of rearward end 40B from independent bag 3 of end 31A thereafter.

For the independent bag 3 that breaks a seal, at first draw back splicing tape 4 by arrow P direction shown in Figure 4, make it to be state shown in Figure 5.In Fig. 5, fixedly sanitary towel's leading section 16, make independent bag 3 to the rotation of arrow Q direction, and the 3rd separate paper 33 that is fixed on the independent bag 3 is peeled off from the 3rd adhesion zone 28.When continuing to peel off the 3rd separate paper 33 backwards, just can peel off first separate paper 31 and second separate paper 32 that is bonded on first separate paper 31 that are bonded on the independent bag 3 continuously.Certainly, the step of the independent bag 3 in Kaifeng is not limited to this, and step described herein just for example.Sanitary towel's user also can be under the state of Fig. 5, before beginning to peel off the 3rd separate paper 33 from sanitary towel's leading section 16, the sanitary towel's rearward end 17 and the rearward end 40B of independent bag 3 are moved along arrow R direction, make sanitary towel 2 and independent bag 3 be in the deployed condition of Fig. 6, the leading section 16 of the 3rd separate paper 33 from sanitary towel begun to peel off.In this case, for the sanitary napkin of the independent bag of packing into, as long as sanitary towel 2 and independent bag 3 are moved fast to arrow R direction just grasp the rearward end 31A of first separate paper 31 that rearward stretches out from the rearward end 40B of independent bag 3.

Under the situation of the independent bag that the uses sanitary towel relatively plastic sheeting of thin extension thick as 5-50 μ m, be difficult to grasp when breaking a seal this thin film, Kaifeng difficulty more when thin film is charged, it is often pretty troublesome to break a seal.Therefore,, preferably make the rigidity height of the rigidity of first separate paper 31, preferably use to be not easy charged material than the thin film that forms independent bag 3 for the sanitary napkin of the independent bag of packing into.Because the rearward end 40B of first separate paper made from this material 31 is very easy to grasp, so the independent bag in Kaifeng is simple to operate.

Fig. 7 and 8 is the identical views of Fig. 6 of example with the expression embodiment of the present invention.In the sanitary napkin of independent bag shown in Figure 7, replace first and second

separate papers

31 and 32 with one the 4th separate paper 51.A face of above-mentioned the 4th separate paper 51 is relative to first adhesion zone 26 clad can, and its another side is relative to second adhesion zone 27 clad can, so two faces of separate paper 51 must above-mentioned relatively adhesion zone be peeled off easily.In addition, one of these two release surface also become the bonding plane to the inner face of independent bag 3.A face separately of Fig. 5 and first and second

separate paper

31,32 of 6 is respectively the face of first and second adhesion zone of lining, and their another sides separately be first and second

separate paper

31,32 each other and the bonding plane of independent bag 3, this is and the 4th separate paper 51 differences.

In the sanitary towel of independent bag of packing into of Fig. 8, adopts long the 5th separate paper 52 first and second

separate papers

31,32 of replacement.A face of the 5th separate paper 52 is the face of first and

second adhesion zone

26,27 of lining, and also is the face that engages facing to independent bag 3 inner faces.The consumption of the consumption of separate paper and Fig. 5 and separate paper shown in Figure 7 is compared more on the configuration space of first and

second wing

23,24 as shown in the drawing.

For the sanitary napkin of the independent bag of packing into of the present invention, because be on covering wears second wing of arm of short underpants, to form second adhesion zone, so can prevent the second wing position deviation and crook.The lining protection of first and second separate paper that first and second adhesion zone that is formed separately from each other on first and second wing is separated from each other; in owing to engage one another between first and second separate paper separate paper is bonded on the independent bag, institute is so that Kaifeng operation and first and second separate paper strip operation of independent bag become continued operation.Because first separate paper adopts and to make than the high flaky material of independent fluid-pressure moulding material membrane rigidity, the rearward end by making this separate paper is rearward extended from an independent bag rearward end and is formed the grip portion independent bag that can break a seal rapidly.Because independent bag and separate paper engage one another for peeling off from sanitary towel integratedly, so can simply they be abandoned as rubbish.
