Abstract
A swab is described formed of a paper stick having opposite ends of less paper density than the rest of the stick. An absorbent covering such as cotton is placed around the ends. The stick is obtained by rolling a paper having left and right edges harmonically cut with at least two amplitude maxima and at least one amplitude minima. Softer stick ends are achieved through this structural arrangement. A cut paper used for forming the swab stick and a manufacturing process are also described.
Claims22
A swab comprising:
- an elongate stem with first and second ends opposite one another, the stem being formed from a rolled paper with left and right edges harmonically cut with each edge having at least two amplitude maxima and at least one amplitude minima, the left and right edges when rolled forming the respective first and second ends;
- and
- an absorbent covering surrounding each of the first and second ends.
A paper with left and right edges harmonically cut with each edge having at least two amplitude maxima and at least one amplitude minima, the left and right edges when rolled forming respective first and second ends of an elongate stem.
A process for preparing a swab comprising:
- (i) preparing a swab stick by cutting a paper along left and right edges in harmonic pattern defining along each edge at least two amplitude maxima and at least one amplitude minima;
- (ii) rolling the cut paper into a stick;
- and
- (iii) placing an absorbent covering around opposite ends of the rolled stick.
