Any fragrance known in the art may be contained in the back sheet, which is in the form of a film, nonwoven fabric or film/nonwoven laminate. Examples of suitable fragrances include lavender, lilac, rose, and the like. The absorbent article of the present invention can prevent contamination of the production line, other non-scented products and the wearer's skin.
Description
Technical field
The present invention relates to a kind of absorbent commodity that comprises the tergite (baffle plate) that contains spice.
Background technology
Existing multiple absorbent commodity in the prior art, for example trousers, adult-incontinence articles, absorbent undergarment, cotton wool, crawlers lining, nursing pad and the analog thereof of baby diaper, training usefulness are used to absorb the body fluid that various physiological processes produces.The body fluid that absorbent commodity absorbed has niff usually.Therefore, numerous means are developed and are used to control the abnormal smells from the patient that absorbent commodity produces.
Most representative in these means is to mix deodorizer or spice in absorbent commodity.
For example, Korean patent No. 1996-15183 and U.S. Patent number 5,429,628 disclose odour absorbents or the spice releasing agent that mixes sealing among the absorbent cores of absorbent commodity or top flat.
U.S. Patent number 5,591,146 disclose a kind of cotton wool, comprise the binding agent of fragrant releasing agent, wherein binding agent can make cotton wool be bonded on wearer's the underwear, and the fragrance releasing agent of microcapsule form is removed from binding agent along with release liner and discharged fragrance.
WO 98/51248 discloses a kind of absorbent commodity, and it comprises at least a quick fragrance component of touching of tergite outer surface that is positioned at, and wherein fragrance component comprises the spice releasing agent of microencapsulation.
Yet the traditional handicraft for preparing this type of absorbent commodity still has problems, and comprises sealing deodorizer or spice and uses the step of the deodorizer or the spice of sealing, and wherein can not to be applied to equably on the absorbent commodity also be an individual problem for Mi Feng deodorizer or spice.Further, if deodorizer or spice are incorporated into the absorbent cores or the top flat of absorbent commodity, also may directly touch wearer's skin.
Disclosure of an invention
Technical problem
The purpose of this invention is to provide a kind of absorbent commodity that does not have the fragrance of the problems referred to above.
Technical scheme
Absorbent commodity of the present invention is characterised in that and mixes spice in the tergite and spice does not have sealed.
Absorbent commodity of the present invention is described below.
As conventional absorbent commodity, absorbent commodity has top flat, absorbent cores and the liquid-tight tergite with liquid permeability.In the present invention, the spice with non-tight is incorporated in the tergite.
This area spice commonly used all can be used for the present invention.The spice that is suitable for comprises single floral type spice such as Garden lavender, Syringa oblata Lindl., Flos Rosae Rugosae and jasmine; All sorts of flowers fragrant perfume, the mixture of promptly single floral type spice; Citrus type spice such as Fructus Citri Limoniae or Fructus Citri tangerinae; Oriental aromatic such as Moschus, succinum and Zibethum; Green or woody type spice; Fatty aldehyde type spice etc.Wherein, the preferred single floral type spice of the present invention such as Garden lavender, Syringa oblata Lindl. and Flos Rosae Rugosae.
Garden lavender spice composed as follows that can be used for the present invention: Essential lavender oil 40 to 60%, linalool or linalool oxide 10 to 30%, citronellol (citronelol) 5 to 10%, acetic acid iso-bornyl ester 10 to 20% and Camphora 5 to 10%.
Camphora strengthens the fragrance of Garden lavender slightly.
The present invention can use by acetic acid linalyl ester 25 to 40%, lavandin oil 40 to 60%, linalool or linalool oxide 5 to 15% and Fructus Citri Limoniae oil 0.01 equally to the 5% Garden lavender spice of forming.
