(ci. 12s-zsm' 9 Claims.

Another object of my invention is to provide A a device of this kind, having a central portion or insert made of gauze, or other material which is extremely absorbent, and which is preferably .more absorbent than the cotton which forms the outer portion of the appliance. Whenever I refer to absorbent cotton, it is to be understood that I may utilize any type of absorbent material or absorbent fabric.

Another object of my invention is to provide a device of this kind, having a; central portion or insert made 'of gauze or other material, said central insert being' completely covered by the exterior material of the appliance.

While I have shown a preferred method of making the improved article, it is to be understood that the claims for the article of manufacture are not to be limited to any particular method of making the same.v Y

Fig. 1 is a top plan view oi one embodiment of the invention, and shown held with its wide face horizontal.

Fig. 2 is a top plan view of the gauze insert.

Fig. 3 is a central sectional view, illustrating the first step in the method of manufacture.

Fig. 4 is a View similar to Fig. 3, showing the second step in the method of manufacture.

Fig. 5 is a side elevation showing the completed Fig. 10 is a side elevation, generally similar to Fig. 5, and showing the article which results from the second method of manufacture.

Referring to Figs. 1, 2 and 3, the improved article comprises a core or aninner portion 2, which can be made'from ordinary woven gauze material, of the type which iscommonly used for making bandages and the like. lThis gauze material may be substituted by any'other type of material or fabric. It is extremely absorbent. The core portion 2 can be made by assembling a number of sheets of thin gauze material, and without the use of any binder or binder means. This core 2 is-very flexible and soft. y According to the .rstexnbodiment of the invention, I apply to the face of the core portion 2, spirally wound layers I and Ia of cotton batting or other absorbent material. The turns or windings of said face layers I and Ia arev held to each other by means of the natural adhesion of said material, and without the use of any binding material or binding means. Said natural adhesion maintains the turns in' contacting position..

When the members assembled as shown in Fig. 3, the outer members I and I a have their edges spaced from each other and separated by the intermediate inner core member 2.

Thread is then passed substantially centrally through the members I and la and 2, so as to form a loop 3 which can be tightened, said thread having projecting thread end portions 4 and la.

Upon tightening the loop 3, by pulling upon the ends l and la, the adjacent faces of the members I and Ia are brought into rm contact with each other, so that the edges 'of members I and la become continuous in eiect. as shown in Fig. 5, and said edges cover the side edges of the core member. Said edges of members I and Ia then adhere to each other. The edges of members I and Ia may be then pressed together, although this is not necessary or preferred. It is then impossible or substantially impossible, to distinguish any lines of separation between the members I and la. The members I and Ia therefore have a continuous outer periphery which completely enclosesand covers the core member 2. 'I'he loop 3 can be maintained in the tightened material by the natural friction of the thread or in any other suitable manner.

It will be understoodl that Fig. 3 and Fig. 4

are exaggerated, as the separation between the members I and Ia will be much less than the separation illustrated in Fig. 3 Vand in Fig. 4, when the parts are assembled, and prior to the tightening of the loop 3.

vSince the gauze or other core member 2 is made of'material which is preferably more absorbent than the material which' is used for making the members I and la, if the appliance I and 2 and Ia have been I is moistened, the core member 2 will become saturated with the moisture, before the outer covering, composed of the members I and la, is

I saturated.

Likewise, since the soft cotton material which is used for making the members I and la, completely encloses the member 2, any contact between the member 2 and the tissue of the body is prevented, thus preventing any irritation.

According to the second method of manufacture, the core member 2 is located between two spirals 6 and 6a, which are made by spirally winding' the

strands

5 and 5a, which are made of absorbent batting, or other suitable material. It will be noted that the spirals can be formed by winding the strands and 5a around a suitable mandrel, which can be made of rigid material. By making this mandrel of small diameter, and winding the turns of the spiral with sufficient tension, said spiral becomes continuous at the inner central portion thereof, when the mandrel is withdrawn, thus producing the continuous spiral shown in Fig. 1 or Fig. 9, in which the various windings or turns abut each other.

Referring to Fig. 6, it may be assumed that this winding action has started at the central points of the circular end faces of the core memy ber 2, and that said spiral winding has been continued, until the peripheries of said spirals are defined by the circular lines which are indicated by the reference numerals 1 and 8.

'I'he winding is then continued, until the spirals have the same diameters as the circular end faces of the core member 2. This is illustrated in Fig. 7, in which the circular lines which are defined by the reference numerals 9 and i0, indicate that the outer diameter of each spiral is equal to the diameter of the end face of the core member 2. y

As shown in Fig. 8, the

strands

5 and 5a are now crossed.

The spiral winding of the

crossed strands

5 and 5a is then continued, so as to make one or more additional layers, which are indicated by the reference letter X in Fig. 9.

There may be one or more of said additional layers of the crossed strands.

The purpose of this is to completely cover the edge of the core member 2, independently of the tension which is exerted by the-loop 3.

The members which are assembled according to the second method are connected in any suitable manner, as for example by passing thread through the members, in order to form the loop 3 and the projecting end-portions 4 and '4a.

However it is one of the advantages of the second method of manufacture, and of the article resulting therefrom that it is not necessary to subject the loop 3 to any substantial tightening, in

order to cause the relatively soft cotton batting to cover the edge of the core 2 completely.

The complete device has a continuous outer -covering of soft absorbent cotton, whose layers are maintained in proper form by the natural adhesion of the layers of absorbent cotton.

I do not wish to be limited to any specific ma terial or materials.

In the broadest aspect of my invention, it includes a core member which is completely enclosed by face material. Said core member 2 is flexible, but it has enough stiffnessA to cause said core member to have a normal predetermined shape, which is disc-like in this embodiment. The core member is stiffer than the face material.

I have shown a preferred embodiment of my invention but lit/is clear that numerous changes and omissions could be made without departing from its spirit.

I claim: 4

A menstrual tampon comprising an absorbent core member having end faces, face members applied to said end faces, and a connecting member holding .the central portion of said core member and the central portions of said face members together in compressed condition, said face members extending laterally beyond said core member and having their edges held substantially abutting `each other by said connecting member so as to cover the edge of said core member. y 2.
