A combination including a packet having a space therein containing a tablet formed of a solid fabric softener composition which is partially water soluble. The packet is formed from a pair of flexible porous open-celled sheets which are joined together in face-to-face relation. A flexible opening formed in the packet leads to the space defined between the pair of flexible porous open-celled sheets. The opening has a normally closed position when the sheets which form the packet are in their expanded condition. However, the opening is expandable to an ope...
In combination, a pair of flexible, porous, open-celled sheets joined together in face-to-face relation to form a packet; said packet including a flexible opening; said opening having a normally closed position when the sheets forming said packet are in their expanded condition; said opening being expandable to an open position by squeezing the sides of said packet in a direction along the axis of said opening; a space defined between said sheets; said space being enclosed by said sheets except at said opening which leads from the exterior of said packet...
