QACHEL. D. DA\H5 ATTORNEYS BIB This invention relates generally to disposable bibs. More particularly, this invention relates to disposable bibs formed from a roll of sheet material which may be individually torn from said sheet material.
The principal object of the present invention is to provide a plurality of disposable bibs formed on a roll of disposable sheet material.
Another object of the present invention is to provide a plurality of disposable bibs formed on a roll of disposable sheet material wherein the bibs are easily torn from the roll.
Another object of the present invention is to provide a plurality of disposable bibs of a simple design which is effective to be held in place by a pair of mutually opposed ties that are adapted to be received and secured around the wearers neck.
A further and more particular object of the present invention is to provide a unique perforated tear line on the disposable sheet material wherein the tear line provides, a) a pair of ties, b) forms the upper or neck portion of the bib and, at the same time, c) forms the bottom of the next succeeding bib.
A further and more general object of the present invention is to provide a plurality of disposable bibs which are easily and simply used and which are far more economical than other forms of packaging bibs.
These and other objects of the present invention will become apparent upon careful perusal of the following specification and claim, including the the accompanying drawing wherein:
FIG. 1 is a plan view of the disposable sheet stock illustrating the position of the perforated tear line forming the successive bibs.
FIG. 2 is a perspective view of a bib being torn along the perforated tear line from the roll of disposable sheet material.
FIG. 3 is a view in elevation of the bib as it would be secured around the neck of the wearer FIG. 4 illustrates the bib positioned upon and around the neck of an infant wearer.
Referring to FIGS. 1 and 2, it may be seen that there is a roll of disposable sheet material generally provided with an inner core 12 to facilitate the rolling of the sheet material. The sheet material is provided with a unique perforated tear line 14 in successive and identical curved shapes along the sheet material to form a plurality of sections 16 which, when torn along the perforated tear line 14, forms the bib I8 as shown in FIGS. 2, 3 and 4 particularly.
The disposable sheet material that may be used includes but is not limited to the polyvinyl synthetic resins of a thermoplastic nature such as polyvinyl chloride, polyvinyl acetate, polyvinyl acetal, polyvinyl alcohol, polyvinylidene chloride, polyethylene, polypropylene, as well as the various polyesters well known to form sheet materials. Additionally, there may be any one of the various cellulose derivatives such as cellulose acetate, butyrate, cellulose nitrate, ethyl cellulose, methyl cellulose, the polycarbonates, and even nylon. Also, the commonly used paper products that are formed into sheet material may be utilized to provide the disposable bibs of the present invention. In fact, the material that is usable is not in any way limited for use as the disposable sheet material.
The perforated tear line 14 is a unique score line that may be impressed into the sheet material by any suitable mechanical means well known in the art. The shape and form of the scoreline is unique in and of itself, particularly with its relationship to successive perforated tear or score lines 14. The tear line 14 is positioned between the outer edges 20 of the sheet material and is essentially a convex curved semioval. As shown, the perforated tear line 14 is convex downwardly towards the playout of the roll. However, the perforated tear line may be simply reversed in mirror image that, viewing FIG. 1, the roll would be at the left hand end of the figure rather than at the right-hand end as is presently illustrated in FIG. 2.
The semioval perforated tear line 14 has its nadir centrally located between the outer edges 20 and the tear line extends upwardly in a smooth curve from the nadir 22 to meet the outer edges 20 at an angle alpha not greater than 40. With such a small angle, there IS formed a tie means 24 composed of should pair of land 28 which are mutually opposed on each side of the sheet material, and which form the ties that may be secured as by a knot 30, as shown in FIG. 3, around the neck of the wearer such as the infant of FIG. 4.
The shape of the perforated tear line 14 must be in the general shape of a substantial semioval. The depth as measured from the nadir vertically to a line joining the ends of the perforated line 14 is shown as the distance X and is important to define the other proportions of the bib. For instance, the distance between the adjacent nadirs should be 1 52 to 3 times the distance X, and the width of the sheet material between edges 20 should be between 1 to 3 times the depth of the perforated tear line 14, or as shown, the distance X.
As may be clearly seen, the incorporation of the peculiar and novel shape of the perforated tear line 14 forms ties 28 and 30 between the outer edges which are of a length X, that is, the depth of the perforated tear line. The depth X of the perforated tear line may vary in commercial use between 5 and 15 inches although such sizes are not critical.
In use, the roll of disposable bib sheet material is placed in a suitable dispenser in hospitals or institutions or in the home, and at any time a bib is desired, it may be torn from the remaining bibs on the sheet material, as shown in FIG. 2. Once removed, the ties 26 and 28 are positioned around the neck of the wearer, as shown in FIGS. 3 and 4, and tied in a knot 30 or otherwise secured together in any convenient fashion to hold the bib 18 secure on the chest of the wearer. It may be seen that with the simple roll of disposable bibs, the convenience facilitates the frequent use and disposing of the bibs after use by the attendant or mother without necessity of washing or cleaning the bib, and always providing a fresh clean sanitary surface to be secured for protection of the wearer.
From the foregoing detailed description, it will be evident that there are a number of changes, adaptations and modifications of the present invention which come within the province of those skilled in the art. However, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the appended claims.
l. A plurality of disposable bibs comprising a roll of disposable sheet material, a plurality of sections successively formed in said sheet material each said section being defined by parallel sides constituting the outer edges of said sheet material, the top and bottom of each section each being defined by mutually identically-shaped convex curved perforated tear lines, each perforated tear line having its nadir centrally located between said outer edges, each said perforated tear line extending outwardly toward said outer edges and intersecting said outer edges at an angle less than 40, the distance between adjacent nadirs being 1.5 to 3 times the depth of said perforated tear line, and the width of said bibs being I to 3 times the depth of said perforated line, tie means formed on said sheet material between each said outer edge and said perforated tear line and being shaped to conform to be tied around the neck of the wearer, bib means formed on said sheet material within and partially bounded at the bottom by said perforated tear line, whereby individual disposable bibs are removable from said roll by tearing said perforated line.
2. The disposable bibs of claim 1 including said sheet material being composed of a thermoplastic.
3. The disposable bibs of claim 1 including said sheet material being composed of paper.
4. The disposable bibs of claim 2 wherein said thermoplastic is polyvinyl chloride, polyvinyl acetate, polyvinylidene chloride, polyethylene, polyester, a cellulose derivative, polypropylene, polyvinyl acital, polyvinyl alcohol, and copolymers thereof.
