Abstract

A humidification device for a stringed musical instrument includes a bag of porous synthetic plastic material which permits water vapor and not water droplets to pass therethrough, the bag having releasable sealing means for opening and closing the bag, a water-absorbing material in the bag, and attachment means carrying the bag and attachable to at least a pair of strings of the instrument to position the bag adjacent or in the instrument body.

Claims

1. A humidification device for a stringed musical instrument having a hollow main body with tensioned strings extending across the body, said device comprising:

a bag comprising porous synthetic plastic material which permits water vapour and not water droplets to pass therethrough, said bag having releasable sealing means for opening and closing the bag,

a water-absorbing material in said bag, and

attachment means carrying said bag and attachable to at least a pair of strings of an instrument to position the bag adjacent or in the instrument body.

2. A humidification device according to claim 1 wherein the bag is of expanded polytetrafluoroethylene.

3. A humidification device according to claim 2 wherein the expanded polytetrafluoroethylene has a pore size of less than about 0.5 microns.

4. A humidification device according to claim 3 wherein the pore size is about 0.02 microns.

5. A humidification device according to claim 1 wherein the water-absorbing material comprises sponge material.

6. A humidification device according to claim 5 wherein the sponge material comprises reticulated foam.

7. A humidification device according to claim 6 wherein the foam has from about 50 to about 100 pores per inch.

8. A humidification device according to claim 7 wherein the foam has from about 80 to about 90 pores per inch.

9. A humidification device according to claim 1 wherein the attachment means comprises a generally wedge-shaped member with the bag being suspended from a narrow end thereof to enable the attachment means to be wedged between a pair of strings of a guitar, said guitar having a hollow main body with a sound hole therein, with the bag extending through the sound hole into the hollow guitar body.

10. A humidification device according to claim 9 wherein the wedge-shaped member carries a clip member engageable with one of the strings to retain the wedge-shaped member in position.

11. A humidification device according to claim 1 wherein the attachment means comprises a plate-like member carrying a pair of hook-shaped members to enable the plate-like member to be mounted under the strings with the hook-shaped members engaging a pair of strings, the bag being carried by the plate-like member so as to be positioned between the plate-like member and the body of the instrument.
