Description

G. T. GRABLE BIB Filed Aug. 20. 1964 INVENTOR. GENE T. GRABLE LEON D. ROSEN,

ATTORNEY United States Patent O 3,299,440 BIB This invention relates to bibs and more particularly to improvements therein.

Bibs are often used on children to protect their clothing. It is sometimes convenient to provide disposable bibs, but they must be of low cost, compactly storable, sturdy, and convenient to use. This invention provides bibs having these and other desirable qualities.

Accordingly, one object of the present invention is to provide a disposable bib which prevents runoff of liquids falling thereon and yet protects the covered clothing.

Another object is to provide a disposable bib having fastening straps which may be easily and securely tied together.

Another object is to provide an easily and efliciently usable bib which is readily cut from a continuous strip of material without waste.

Another object is to provide a continuous strip of disposable bibs, from which individual bibs can be removed and easily used.

Another object is to provide a continuous strip from which individual bibs of sturdy construction can be removed.

Another object is to provide a continuous strip of easily fastened bibs which are of a shape which enables their protection of clothing with a minimum of material, and wherein all of the strip material is efficiently utilized.

The foregoing and other objects are attained by a bib comprising a first layer of absorbent material such as porous paper to prevent runoff of liquids spilled thereon and a thin second layer of an impermeable material such as a plastic to prevent liquids from penetrating to the clothing covered by the bib. The bib of the invention includes an apron portion and two straps, the space between the straps being of the same shape as the outside of the apron portion to enable the production of bibs from a continuous strip of material without waste. The bibs of this invention are easily fastened because the second layer thereof is generally of a deformable but somewhat resilient plastic material. Thus, when the bib straps are tied together, they form a knot which is not likely to undo itself. I

The bibs of the invention are provided in a compactly storable and easily dispensed form by manufacturing them as a strip. The strip is as wide as each bib, and perforations are punched therein to define individual bibs. The user mereely tears along one perforation to remove one bib at a time from the roll. The bibs thus removed are ready for use without further tearing or manipulation, and are used merely by tying the resulting straps around the bib-wearers neck.

The novel features that are considered characteristic of this invention are set forth with particularity in the appended claims. The invention itself, both as to its organization and manner of use, as well as additional objects and advantages thereof, will best be understood from the following description when read in connection with the accompanying drawings, in which:

FIGURE 1 is a perspective view of a rolled strip containing bibs, which is constructed in accordance with the present invention;

FIG. 2 is a partial edge elevation view of a bib constructed in accordance with the invention;

FIG. 3 is a pictorial view of a bib shown in use on a wearer;

FIG. 4 is a front elevation view of an individual bib such as one removed from the strip of FIG. 1; and

FIG. 5 is a front elevation view of another embodiment of a bib constructed in accordance with the invention.

Reference is now made to the drawings and particularly to FIG. 1 which illustrates a strip 10 of material partially wound on a roll 11, the strip having perforation lines 12 which define individual bibs 14. By tearing the strip 10 along a perforation line 12, a single bib of the form shown in FIG. 4 is removed from the strip.

Each bib 14 of the type shown in FIG. 4 includes an apron 18 which serves to catch food, and two straps 20 which enable the fastening of the bib around the wearers neck. The apron 18 includes a breast portion 22 which generally covers the breast or stomach of the wearer, and a neck portion 26 which is generally positioned against the neck of the wearer. The straps 20 depend from either side of the neck portion 26, and extend parallel to each other.

The bib 14 is symmetrical about a centerline 32. The outline of the bib may be defined as four edges. Two of these are parallel edges 34 which are the edges of the strip of material from which the bib is removed and which form outer edges of the straps 20. An apron edge 36 extends between the edges 34 and around the breast portion 22, thereby defining most of the apron 18. An inner strap edge 38 extends between the edges 34 and forms inner edges of the straps 20 and part of the outline of the neck portion 26 of the apron. The shape of the apron edge 36 is geometrically congruent with the shape of the inner strap edge 38. The congruency of the edges enables the bibs to be formed from a continuous strip of material without waste and/or to be packaged as a continuous strip of constant width as shown in FIG. 1.

Inasmuch as the inner edges of the straps 20 define the apron 18 and vise versa, the

edges

36 and 38 are shaped so as to simultaneously optimize the shape of both the straps and the apron. The intersection 40 of the apron edge 36 and edge 34 would generally be a smooth, continuous line if it were not necessary to make the apron edge define part of another bib of the strap. However, the elimination of the corner at 40 would results in the extreme ends of the straps (on the next bib of the strip) being very narrow and of little strength; if the bib were tied at such narrow ends, the ends might tear. Accordingly, the straps 20 are provided with ends which are not extremely narrow; generally the angle A between the inner strap edge 38 and the edges 34 is at least about 30.

The apron 18 is preferably shaped so that it is wide to protect large areas of clothing. Accordingly, the inner edges of the straps 20 are substantially parallel to the outer edges 34 throughout most of the length of the straps. At the base portions 42 of the straps, where the straps meet the neck portion 26 of the apron, the inner edge of the straps curve inwardly so as to form wide bases. The bases 42 of the straps generally receive the full shear and tension forces applied to the straps in pulling the bib snugly around the wearers neck and tying it, so they are wide to prevent tearing. Thesrounding of the inner edges of the straps at the base 42 is also desirable to enable the bib to snugly fit the neck of the wearer. By placing the intersection 40 of the strap and apron edges approximately even with the portion of edge 38 which defines the apron neck portion 26 (i.e. the two intersections 40 of each bib and the middle of the inner strap edge 38 all lie on an imaginary straight line) the bases 42 of the straps are wide and therefore strong.

Generally the center portions of the straps 20, which have almost parallel sides, are no wider than about oneeighth the width of the strip from which the bibs are formed. This enables the straps to easily be wrapped about the wearers neck and to be tied together. The straps may be narrower than this, but are then likely to tear.

The construction of the bib includes an absorbent top layer 44 and an impermeable bottom layer 46, as shown in FIG. 2. The top layer 44 is of a paper towel material or the like to enable its absorption of liquid food spilled thereon, and to prevent the liquid from flowing or dribbling off the bib and onto the wearers clothing. The impermeable layer 46 is of a thin impermeable material to prevent any liquid which is absorbed by the top layer 44 from penetrating to the covered clothing.

When the bib is tied around the wearers neck, the knot must hold itself securely. Generally, straps of a paper-towel-like material will not hold together unless the tying knot is very tight. However, before a knot can be pulled tight, the material is likely to tear. It is found that the use of a deformable but resilient plastic backing layer 46 enables the straps to hold a knot well. When a knot is being pulled tight, the deformable plastic lies between the adjacent paper strap loops. As soon as the tension on the straps is released, the plastic springs back somewhat and holds together the paper portions which tend to separate. The plastic is largely deformed to the shape of the knot so it does not tend to undo the knot;

however, the plastic expands laterally a small amount when the lengthwise tension on the straps is removed.

It has been found that a paper towel material of approximately six-thousandths inch thickness backed by a layer of Saran, a trademark for vinylidene chloride sheet material, manufactured by the Dow Chemical Company, Inc. of Midland, Michigan, of approximately onehalf thousandth inch thickness, provides an easily tied bib construction. having the deformable characteristics of Saran can also be used.

Although the embodiment shown in FIG. 4 is especially useful as explained hereinbefore, other shapes can be employed. The embodiment shown in FIG. 5, for example, has straps 50 and an apron 52 of a form which enables its production from a continuous strip without waste, and which can be packaged on a continuous strip or roll. This embodiment, however, lacks several of the advantages possessed by the embodiment of FIG. 4, which have been set forth.

The particular bibs described herein may be packaged as a continuous strip, but may also be packaged in stacks or in othermanners. Additionally, other shapes of bibs may be employed which include only some of the features set forth herein. Thus, while particular embodiments of the invention have been described herein, the invention is not limited thereby, but is of the full scope of the appended claims.
