3 Claims. or. 223-109 This present invention relates to the general art of pin cushions and more particularly to a pin cushion having a block of sponge-like material, such as sponge rubber, which is impregnated near its center with preferably a paste-like corrosive inhibitor. The sponge blockis'then covered with pervious cloth on all six sides so that pins can be easily passed through it. Attached to the covering is a safety pin orv similar securing device so that the pin. cushion can be easily attached in a hanging positiontoa child's bathinette or crib. V

The handling of and use of. safety pins in connectionwith securing infants diapers in place is very appreciablycomplicated by the fact that mine, particularly, has avery corrosive: effect. upon the safety pin structure and most especially, the pointed end of the pin that must be repeatedlyv passed. through the rather substantial, material from which infants diapers are made. Persons attending infants with resulting necessity for frequent changes of diapers have been. confronted. with: this problem for a longtime. a

The diaper material itself. is normallya. relatively heavy, closely woven. material. with considerable nap and it. is almost invariably the rule that the diapers are folded so that the pin normally is passedv through not less: than two thicknesses of the diaper. and in most cases, four thicknesses, dependingsomewhat on. the manner in .which'the diapers are folded. It is very desirable that the pins be capable of passing through thematerials without stoppage or arresting. of the. movement to the end that it. will not be necessary to apply excess pressure in inserting the pin which might easily cause slippage and injury to the infant by being pricked with the pin.

The ordinary safety pin in normal use by the average mother will usually be found to be actually contaminated in the tip area, and this means that even minor punctures or scratches eifected on the infants skin may and, in many cases, have resulted in very serious infections. In this present invention means are provided for de-contamination of the safety pin in its normal storage period, or even the relatively short periods when the pins are taken from a diaper and before they are replaced in a clean diaper.

This present invention contemplates that the pins will be stuck into the co-rosive inhibitor treated area of the'pin cushion-proper so that corrosion itself will be inhibited. Each passage of the pin into the zone interiorily of the pin cushion will, in effect, be a cleaning action as well as an inhibiting action. It is, therefore, believed that a very worthwhile device has been provided which will very satisfactorily overcome many of the deficiencies in the technique formerly employed in the handling of safety pins for the fastening of infants diapers and other garments.

A principal object of the present invention is to provide a handy, convenient to use pin cushion proportioned and particularly arranged to accept the pointed pin portions of safety pins and treat the point and adjacent portion of the pin with a corrosive inhibitor.

A further object of this present invention is to provide 2,873,901 Patented Feb. 17, 195? 'ice a safety pin receiving pador cushion arranged so that the W pin passes through an area of untreated resilient material and then enters a treated area. When the pin is withdrawn the excess of the inhibitor is wiped off the pin as it passes through the untreated area of the pad so that it is ready for'use in a clean condition.

A further object of this present invention is to provide a safety pin corrosion inhibiting pad or cushion which provides a sanitary treatment for the endsof safety pins and straight pins having the same generalpin length, that is factory sealed and will give long periods of satisfactory service but cannot be re-treated, thus, guarding against complex chemical reaction and contamination.

Further objects,.advantages and. capabilities will be ap-- parent from the description and disclosure in the drawings, or may be comprehended or are inherent in the device.

Referring more particularly tothe disclosure in the drawings, the numeral 10 designates; a block of pervious resilient material suitable as a receptacle for pins and the like. Quite a variety of materials would be suitable, the felted materials, particularly-those of plastic base,.have

been used for similar uses, however, theideal material. ap-

pears to be either sponge rubber or the plastic sponge-mar terials. These materials are provided with alarge num- -ber of interstices which can befilled witha suitable corrosive-inhib'itor and do not tendto weep or penetrate to the outside of the-block where itwould cause discoloration ofi the; preferably, fabric coveringll- In a preferred arrangement it has been found expeditions to slit the block, as at 14, from one side only, and to then spread the slit portions apart, after the showing of Figures 3 and 5. Suitable corrosion inhibitives, particularly of a creamy or paste-like consistency are available on the market for cleaning and polishing table silverware. With the average sponge-like block, this type of material seems preferable to a liquid which tends to soak throughout the sponge and to soil and come out through the cloth covering. A cloth covering entirely around the block is more preferable to an imprevious covering in part, in that the pins can be stuck in from any side.

Various means have been employed to impregnate the sponge block with the corrosion inhibitive such as injecting the material through a hollow needle or tube, but a preferred arrangement follows the showing of Figures 3, 4 and 5 wherein the paste-like material is introduced into an opening 14 formed by slitting the block 10 with a knife entering from only one of the six faces of block 10. After the inhibitor is fully positioned, the two sides or walls of opening 14 are cemented together as by cement, indicated in Figure 3 at 16 and 18. This seals the block so that the inhibitor is fully enclosed and yet does not interfere with the passage of the pin point, as 20, through even the cemented joint.

After the inhibitor has been in this sponge for a reaa large volume inside the sponge block so that the safety pin or the straight pin, if desired, as 22, may be introduced from any of the six faces of the block toward the center of the block and the point 20 will be fully engaged in the inhibitor and also will have the mechanical cleaning of the point as it goes into the block and then when the pin is to be used, the withdrawal of the pin wipes off the bulk of the excess within the impregnated area with the final cleaning occurring in the un-impregnated area, which is shown in the conventional sectioning in Figure 4, as at 24.

Many forms of corrosion inhibitives may be used, probably the most satisfactory is the general class of cleaning compounds such as are used in cleaning silverware. These are normally a combination of cleaning and inhibitive agents. A suitable inhibitor can be provided by considering the type of corrosion existent. This is normally a metal compound which has been created by association with uric acid from the urine and this can be best counteracted by some of the milder alkalies. A paste made of water and ordinary baking soda (sodium bicarbonate) serves very effectively to neutralize the acid and if the device is readily available so that the pins can be inserted in it before the uric acid has had an opportunity to coact with the metal, then a full inhibiting is achieved. It is further desirable that a mild vegetable oil soap such as castile soap be employed which can be mixed with the concentrated soda solution so that a paste results. A mixture of this kind serves well to both neutralize the acid and to clean the point of the pins and neither ingredient, normally, enters into chemical reaction with each other or the water involved and in case the infant happens to be pricked with the point of the pin, there is no danger of infection or rash as might be true if stronger alkalies or detergents were used. A finely divided neutral abrasive, such as pumice, may be used as a further admixture to assist in the mechanical cleaning of the point of the A manner of using this device is believed to be quite well illustrated in Figures 1 and 2. It has been found convenient to employ a safety pin, as 26, which is secured as by a stitched-on tab 28, to the cloth covering 12 of the block so that the same may be easily attached as to the cloth covering of the bathinette indicated in Figure 1 at 30, or the safety pin may be used to secure the block to a childs crib or even to the clothing of the infant's attendant. The pins, as 22, should be then left open as they 4 are removed from the diaper and stuck into the block, preferably in a radial manner, after the showing of Figure 4, so that the extreme points 20 of the pins are directed into the area of greatest concentration which should be preferably in the center of the sponge block. It therefore follows that the overall size of the sponge block 10 should be such that, for the type of pins used, the block would be of a size to permit the pin reaching the center but preferably not past the center, as that is the point of greatest concentration, and the cleaning of the pin in removing the same will be best affected if only the extreme point is in the area of greatest concentration of the inhibitor. I

It is believed that it will be clearly apparent from the above description and the disclosure in the drawings that the invention comprehends a novel construction of a safety pin corrosive inhibitor.

Having thus disclosed my invention, I claim:

1. A diaper pin holder, comprising: a block of sponge material; a chamber in the approximate center of said block and a paste, chemical corrosive inhibitor disposed in said chamber.

2. The subject matter of claim 1 in which the chemical inhibitor is a paste consisting of sodium bicarbonate, a mild vegetable oil soap, a neutral finely divided abrasive and water.

3. The subject matter of claim 1 in which said block has a fabric covering; means secured to said fabric covering adapted to hold an opened safety pin with its hinge portion uppermost near the top of said sponge block and with its point outwardly and downwardly extending.
