Title: Sanitary absorbent article with an adhesive positioning system covered by release strips linked to one another and method and apparatus for packaging the absorbent article
Inventor: BARR JAMES P
IPC: A61F13/60
Filed: 1995-06-15
Granted: 2000-09-19
Abstract: A   sanitary   napkin   with   laterally   projecting positioning tabs.  The adhesive securement system of the sanitary napkin includes three adhesive zones in a spaced apart relationship, namely one zone on the main body of the sanitary napkin and one zone on the undergarment facing surface of each positioning tab.  A quick-remove peelable protective  layer  covers  the  adhesive  zones  when  the sanitary napkin is not  in use.   The protective  layer includes a primary release strip extending longitudinally on the sanitary napkin to cover the adhesive zone on the main  body  and  a  transversal  secondary  release  strip overlaying the adhesive zones on the positioning tabs. This arrangement allows to remove the entire protective layer in a single peel-off stroke.   The invention also relates to a method and apparatus for folding a positioning tab of the sanitary napkin over its main body during a packaging operation that inserts the sanitary napkin in a disposable pouch.   The method comprises  the  steps  of creating a crease in the transverse release strip of the protective layer, near the juncture between the positioning tab  and  the  main body of  the  sanitary napkin.    The transverse release strip is made of sufficiently rigid paper material so the crease maintains the positioning tab in a folded condition during the packaging operation.

Abstract: L'invention concerne un procédé de nettoyage d'une surface métallique. Il consiste a) à mettre cette surface métallique en contact avec une solution de nettoyage alcaline chargée d'éliminer des contaminants tels que des souillures et de la graisse; et b) à mettre cette surface métallique en contact avec une solution de nettoyage contenant un ion acide de terres rares pour éliminer la saleté formée sur cette surface métallique lors de l'étape a). On peut utiliser ce procédé pour préparer une surface métallique à un processus de revêtement ultérieur qui comporte une étape supplémentaire consistant à mettre la surface métallique en contact avec une solution aqueuse de revêtement contenant un ion acide de terres rares et des cations de terres rares pouvant présenter plus d'un état de valence, ce qui accroît le pH de cette solution de revêtement, près de la surface métallique, jusqu'à une valeur suffisante pour précipiter un ou plusieurs composés des terres rares qui forment alors un revêtement sur la surface métallique. L'invention concerne aussi une solution de nettoyage aqueuse, contenant un ion acide de terres rares, utilisable à l'étape b) du processus inventé. Cette solution comporte des ions d'une ou plusieurs terres rares présents en quantité efficace pour éliminer la saleté d'une surface métallique ayant été auparavant mise en contact avec une solution de nettoyage alcaline. L'invention concerne aussi une surface métallique traitée par le procédé inventé.
