The present invention relates to a reusable and machine washable hypoallergic
pillow
cover/protector. This is comprised of 3-layers of laminated fabric that is
water-impermeable,
breathable, and antimicrobial. Generic pillow covers/protectors can be
assembled with sewing
machines which leave gaps in the fabric or include generic zippers with gaps
that both allow for the
transmission of allergens between the user and the pillow. The invention
utilizes ultrasonic
welding/bonding technology, waterproof tapes, and a hermetic zipper to render
the cover allergen-
proof. This would provide a hygienic and hypoallergenic sleeping environment
for personal use at
home, travel use in public accommodations, and/or clinical environments.
La présente invention concerne une taie doreiller hypoallergénique réutilisable et lavable à la machine. Elle est composée de trois couches de tissu laminé imperméable à leau, respirant et antimicrobien. Les taies doreiller génériques peuvent être assemblées à la machine à coudre, ce qui laisse des espaces dans le tissu, ou comprennent des fermetures à glissière, qui permettent la transmission dallergènes entre lutilisateur et loreiller. Linvention utilise une technologie de soudage/adhésion par ultrasons, des rubans étanches à leau et des fermetures à glissière hermétiques pour que la taie soit à lépreuve des allergènes. Cela permettrait un environnement de sommeil hygiénique et hypoallergénique pour lutilisation personnel à la maison, lutilisation de voyage dans les locaux dhabitation publics et/ou dans les environnements cliniques.
