Patent CA-2531872-A1 (CA)
Inventor: CYMBOL REA E
IPC: A41B13/10
Filed: 2006-01-09
Abstract: A barrier against soiling to the wearer, this functional, esthetically pleasing and easy to use bib comprises a body made of washable, flexible, durable and non-porous material with a front and a back. The body includes two increasingly widening semi-circular upper sections that protect the wearer's shoulders from soiling while also becoming the method of securing around the wearer's neck with adjustable co-operative fasteners that fasten these two upper sections together to accommodate a range of neck sizes.  In fastening the upper sections together, a portion of the bib body arcs outwardly to conform to the wearer's body and due to the placement of the increasingly widening semi-circular upper sections over the shoulders of the wearer, rotation of the bib is virtually eliminated thus preventing solid or liquid food material from coming into contact with the user at its sides. The lower body of the bib forms into a bowed pocket for catching and retaining food particles and liquid thus shielding the user from soiling. The pocket, which has been pre-prepared by folding the body fabric under and then affixing together along the sides and top for extra rigidity, is formed firstly by folding the lowest portion of the body, which is the pre-prepared front pocket flap, upwards toward the front of the bib and fastening with a corresponding co-operative fastener on each side.  Secondly it is formed by folding the bottom right and left comers of the pocket around to the backside of the bib and fastening to the corresponding co-operative fasteners on the backside with the edge being parallel to the pocket formed in front. This pocket is not intended to be temporary while being used by the wearer and unfastens for the purpose of wiping and/or washing the body of the bib when removed from the wearer.  The integrity of this pocket to retain liquid and food particles is assured and maintained by the special manner in which it is folded and constructed, by eliminating any folds within the pocket and also by eliminating any perforations caused by affixing within the pocket, which could cause liquid to leak. The resulting pocket does not just minimize liquid leakage, it prevents liquid leakage and is free from applied trim along its edges providing a very easy to clean surface when unfastened, to be cleaned by wiping or washing.
