Problems solved by technology

With indicators made of paper, the wetted range of the core often does not coincide with that of the indicator, making it difficult to determine the actual wetted range of the core from the wetted range of the indicator
Therefore, known indicators sometimes do not provide enough information for mothers to obtain

Embodiment Construction

[0016] Details of the indicator of the present invention will be more fully understood from the description given below of a disposable pant-type diaper as one embodiment of a body fluid absorbent article with reference to the accompanying drawings.

[0017] Depend on figure 1 The disposable pant diaper 1 shown in the partially cut-away perspective view comprises a liquid-permeable topsheet 2, a liquid-impermeable backsheet 3 and an absorbent core 4 between these two layers 2,3. Portions of the top layer 2 and bottom layer 3 that extend outward beyond the peripheral edge of the core 4 overlap and are joined together. The diaper 1 has a front waist region 6 , a rear waist region 7 and a crotch region 8 extending between the waist regions 6 , 7 . Such as figure 1 As shown, the side edge regions of the front and rear waist regions 6, 7 overlap and join together at a plurality of locations 10, with the top layer 2 located inside, said locations 10 being spaced apart in the verti...

Abstract

An indicator (18) disposed between the liquid-impermeable sheet (3) and core (4) of a body fluid absorbable article comprises a water absorbable sheet (21) and a display element (19) intimately contacted with the water absorbable sheet (21). For the water absorbable sheet (21), use is made of a porous thermoplastic film whose overall light transmittance is not more than 40% in the dry state and not less than 60% in the water absorbing state.

Description

technical field [0001] The present invention relates to an indicator for use in conjunction with a bodily fluid-absorbent article such as a disposable diaper and which provides a visual indication of whether the body fluid-absorbent core of the article is wet. Background technique [0002] Various indicators are known which are generally used to visually sense whether urination has occurred from the outside of the backsheet of a bodily fluid-absorbent article. For example, an indicator disclosed in Japanese Patent Application Laid-Open No. 1997-299401A is interposed between a backsheet and a bodily fluid-absorbent core. The indicator includes an ink layer for viewing when the layer is wetted and an ink carrying layer interposed between the ink layer and the underlayer to maintain intimate contact with the ink layer. The ink carrying layer contains a surfactant. The document cited above discloses an embodiment of the indicator in which the ink-carrying layer is made of pape...
