P&G WIPO Applications in May/June 2008

In May/June 2008 P&G published a few Internatonal Patents Applications. Let's see what they are dealing with

The most interesting application is related to the usage of a replaceable core in a training pant (WO 2008/050309). This document is an extension of previous applications already published in the past months. This time what it is involved in the application is the method for using the diaper (and the changeable core) to selectively enable or disable the wetness indicator. Anyway it is interesting to know that P&G is working on this type of construction and maybe we will see soon something similar on the market.

Another application of interest could be the WO2008/050275 related to a new construction of closing system. We all know how it is easy to damage hooks of mechanical closures during conversion process. This application covers a design to fold properly a MF tab avoiding risk of pop open.

It worth a mention the application WO2008/056315 where it is claimed type of graphics to be applied to training pants to let them look more real pants alike. Good idea but it seems facing some conflicts with other previous applications

Then we find an interesting application on individually wrapping of sanitary napkins (WO 2008/075290). The aim is to reduce the thickness of wrapping film and avoid damages during the process (eg hot melt application). The result is pretty interesting, howewer the relevant search report shows some conflicts with previous applications.

The last application I would like to highlight this time is the WO2008/056315. Here it is described a method to manufacture a diaper with changeable core replaceble from outside "on the fly". It will be one of the applications to deal with when somebody else decide to follow P&G on this field especially converting machinery manufacturer
