Paper tissue with high lotion transferability
Abstract
A paper tissue and products made from paper tissue, such as paper handkerchiefs, facial tissues, bath and cosmetic tissues, paper tissue wipes of any kinds and the like. The invention describes both the process for making a smooth and absorbent lotioned paper tissue, with high transferability of the lotion. The process steps comprises the steps of (a) providing a paper tissue web continuously moving next to a lotion application unit comprising at least one rotating surface, (b) transferring said lotion onto one rotating surface, (c) expulsing said lotion from the said rotating surface into a stream of lotion droplets, by primarily the centrifugal force of the rotation of said rotating surface, (d) intercepting said paper tissue with said stream of lotion droplets. The invention also describes a paper tissue comprising a lotion distributed as discrete deposits on its surface. The deposits have a high local concentration of lotion and cover a relatively small area of the tissue.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A process of applying a lotion onto paper tissue comprising the steps of providing a paper tissue web continuously moving next to a lotion application unit comprising at least one rotating surface, the process further comprises the steps of:
transferring said lotion onto one rotating surface; expulsing said lotion from the said rotating surface into a stream of lotion droplets, by primarily the centrifugal force of the rotation of said rotating surface; optionally reducing the angle of which the stream of droplet is expulsed, optionally by adjustable flaps adjusted to match the width of the desired application; intercepting said paper tissue with said stream of lotion droplets; and optionally, collecting the lotion not intercepted by said paper tissue and recycling said collected lotion.
2 . The process of claim 1 wherein said application also comprises the use of an electrostatic mean targeted at facilitating said process.
3 . The process of claim 1 wherein said lotion is solid, semi-solid, liquid or semi-liquid, is expulsed from said rotating surface in a liquid or quasi-liquid form and is solid or quasi-solid after the interception by said paper tissue.
4 . The process of claim 1 wherein at least 20% of said droplets are of a volume of at least 3×10 −4 μl.
5 . The process of claim 1 wherein said droplets form deposits on said tissue and have a basis weight of at least 11 g/sqm.
6 . The process of claim 1 wherein said tissue receives said lotion at a basis weight of equal or less 9 g/sqm.
7 . The process of claim 1 wherein the ratio of said lotion basis weight of said deposits to said lotion basis weight of said tissue is at least 5.
8 . The process of claim 1 wherein a portion of said tissue are not affected by said lotion and wherein ratio R is defined as

and wherein said ratio R is less than 0.15 sqm/g.
9 . The process of claim 1 wherein the position of at least 2 of said rotating surfaces and optionally of said flaps induces at least one paper tissue area with lotion juxtaposed to at least one paper tissue area without lotion.Join the waitlist — get patent alerts
