Oct. 2l, 1952 M. H. ABBOTT DISPOSABLE SANDAL OF PAPER OR THE LIKE Filed Oct. 3l, 1950 Maggio@ Patented st. 2l, 1952 UNITED'STATES PATENT 'oi-FICE j DISPOSABLE SANDAL OF PAPER OR THE LIKE "This invention relates to a sandal of paper or the like and in particular to a disposable one-use sandal of the type which utilizes a sole of paperboard to which is secured a creped toe-receiving cap.l

This sandal is intended primarily for use around hospitals, swimming pools, hotels, public baths, locker rooms and the like. Travelers will appreciate these sandals on overnight trains. on oversea nights, and on shipboard.

An object of this invention is to provide an inexpensive, disposable, sanitary sandal which is light and comfortable.

Another object is to provide a sandal having these attributes which may be easily packed so as to occupy a minimum of space.

Other objects and advantages will become apparent from a consideration of the accompanying description and drawing wherein:

Figure 1 is a perspective View of my sandal in its flat state as when first produced;

Fig. 2 is a side elevation of the sandal, showing the cap expanded upwardly as when in use or thereafter; and

Fig. 3 is a perspective view showing a tab at the rear of the sandal heel as when pressured to bend in response to resting of the foot upon its heel.

As shown, the sandal comprises a sole S to which is aixed a cap C. The sole may be made of a cellular paper-board having double faces lil and l2 between which are transverse corrugations i4. The cellular structure thus formed serves to insulate and prevent cold floor temperatures from being conducted to the foot of the wearer. The heel end portion of the sole S terminates in a crescent-shaped tab t which is formed by a curved incision it extending through substantially 180 (see Fig. 1) A scored line 2l on the sole face i@ extends outwardly from each end of the incision and transversely of the sole to facilitate upward bending of the tab and, if desired, severance of the tab from the sole.

The cap C is made of a creped paper having a large stretching capacity. Approximately 200% stretching capacity is found to be an optimum, all factors considered. It is laid flat on the toe end portion of the sole S with the rugae 22 running lengthwise thereof so as to permit trans verse stretching. The side and toe edge por tions 24 are secured to the sole by suitable means, such as an adhesive or staples. Three pairs of scored lines 26, 2l and 28 are impressed transversely of the cap and in intersection with the rugae 22 crossed thereby, and therethrough upon l the upper sole face I0 Where theyvare designated as 30, 3l and 32, respectively (see Fig. 2). These scored lines are spaced approximately as shown in Fig. 1, and are applied after the cap has been afxed to the sole. The forming of the for-l ward score lines 30 upon the upper sole facelll contracts the toe portion of the sole S and exerts a longitudinal pull thereon such as to pull it upwardly to a slight extent, as shown in Fig. 2; also the scoring on the sole face I0 at all three places 3D, 3l and 32` provides transverse lines of weakness at those points to enhance the ilexibility thereof, sov that when the wearer is walking, the sole readily bends upwardly in response to the natural pressure from the foot. The sole corrugations i4 are disposed transversely to aid in this bending function. The scoring also acts to modify the elastic properties of the crepe paper to oppose return of the cap to the original at state, following an initial arching thereof which results from insertion of the toes and instep of a foot beneath the cap.

The tab t serves a twofold purpose. The length of the sandal may be reduced for users having small feet by simply tearing off the tab. Another feature is that the tab will bend upwardly when the heel of the wearer is rested on a floor or foot stool, as so often is done by one who is reclining in a deck chair. In this position the tab serves as a protective sole for the back of the wearers heel, and simultaneously prevents the sandal from being forced upwardly and oi of the wearers foot.

The creped cap, when first assembled with the sole, lies ilat thereon and in this condition is convenient for packing and storing. When iirst used, however, the cap is stretched transversely into the form of an arch and tends to remain so indefinitely; because of this fact the sandal becomes conditioned for the foot to re-enter beneath the cap Without the hand lending any assistance in this operation. This is a feature of advantage, particularly for persons who are obese or invalids. Furthermore, the degree of cap stretch is so great that a single-size sandal will fit widely differing sizes of feet, thereby dispensing with the necessity of stocking several sizes of sandals for the accommodation of a large number of persons.

I claim:

l. In a one-use sandal of the type which utilizes a sole of paper-board to the top face of which is secured the side and front margins of a flat crepe paper cap having its rugae extending lengthwise of the sole, the feature of improvement which comprises the provision of scored lines extending transversely of the cap at varying distances longitudinally thereof and in intersection with the rugae crossed thereby at an angle of substantially 90, each scored line acting to lessen the resilient properties of the crepe paper to oppose return of the cap to its original fiat state following an initial arching thereof` occasioned by insertion of the toes and instep of a foot beneath the cap.

2. In a one-use sandal of the type which utilizes a sole of transversely corrugated paperboard to the top face of which is secured the side and front margins of a at crepe paper cap having its rugae extending lengthwise of thev sole, the feature of improvement which comprises the provision of scored lines extending transversely of the cap at varying distances longitudinally thereof and in intersection with the rugae crossed thereby at an angle of substantially 90, each scored line acting to lessenthe resilient properties of the crepe paper to oppose return of the cap to its original flat stateV following an initial arching thereof occasionedby insertion of the toes` and instep of a foot beneath the cap, at least one of the scored lines to- 4 Ward the rear end of the cap being impressed also on the top face of the sole therebelow to tension the sole in a direction longitudinally thereof and produce an up-pull at the toe portion of the sole.
