6 Claims, 9 Drawing Figures 1 FEMININE USE PADS carry. Also, due to its size and its considerable section,
its application is rather difficult.
In order to eliminate the before mentioned inconveniencies, the improvements which are the object of the present invention have beencontrived, which give as a result a new kind of pad, provided with peculiarities which make it much more advantageous than other de vices meant for the same purpose.
These advantages are the following:
I. Thepad is easily applied, due to its special shape and characteristics.
2. The pad has a minimum volume per unit, which allows the use of small containers, provided with a great number of pads. i
3. The pad has high absorbent imbibent.
4. The pad is covered by a solid jelly-like material for lubrication purposes and for making the pad relatively rigid, thus making application very easy, and which jelly-like material is easily dissolved by body heat.
Generally speaking, the improvements included in the object of the present invention include i a dehypower, and is greatly drated and pressed cellulose body, of high moisture imbibent characteristics, which is provided with a coating orsheath made up of a solid jelly-like material.
The above mentioned sheath can exhibit a continuous wall or layer, which has no effect whatsoever for the passage ,of moisture and secretions towards the internal pressed body, as the mentioned sheath, due-to its characteristics mentioned above, easily dissolves with body heat. I i
In anothervariation of the invention, there is the possibility of providing the walls of the sheath and the central body with bo'rings, which would be of aid for'the passage of moisture towards the interior pressed cellulose body, thus establishing passages or inlets for the flow, which enter the cellulose interior body making it expand or swell so that it becomes almost as thick as as it is wide, the body thus acquiring its normal volume of use.
The mentioned coating applied to the cellulose body is made of solid jelly or other jelly like products.
Another of the variations comprises several borings in the pad throug which the traction thread passes, thus describing a sinuous run for same, which will give'it much more strength. I
In another variation, the traction thread is made up starting from a thread which is sewn lengthwise on the pad, the prolongation or extensionof which 'gives place to the end of the traction thread. Said thread'exhibits very loose stitches, thus allowing the expansion or swelling of the pad.
In all the mentioned cases, the pad itself is obtained by punch-pressing of sheets, in order. to produce rectangular oblong pieces, which in some cases may have a rounded application extremity. In the case of oblong rectangular bodies, the sheath or coating of solid jelly has a rounded application or introduction extremity, and preferably it is provided with an axial inlet of a main boring for the passage of the flow and secretions. Both the interior material and the sheath or coating can be perfumed or deoderized, either one of them or both at the same time.
In the drawings:
FIG. 1 shows a top view of the cellulose body, of dehydrated cellulose and pressed in an extra flat shape, which forms part of the pad.
FIG. 2 is a side view according to the previous draw- FIG. 3 is a top view of the sheath covering-or coating for the cellulose body.
FIG. 4 is a longitudinal sectional view of the mentioned sheath.
FIG. 5 represents a complete perspective view of both elements.
FIG. 6 is a longitudinal sectional view of the previous figure.
FIG. 7 shows a top view of the dehydrated pressed cellulose body which is the inner part of the pad, provided with a thread sewn in a longitudinal manner, the free end of which forms the traction thread.
, FIG. Sis a side view, according to the previous figure, in which the loose stitches of the longitudinal thread can be seen, the end of which gives place to the traction thread. 1
FIG; 9 represents a top or plan view of the pad, in which the coating or sheath of jelly has been represented in dot lines, together with its rounded off introduction or application extremity.
In reference to the Figures, it can be seen that they are internal use pads, which comprise a cellulose body 1, dehydrated and pressed, which have an extra flat shape, said body being highly imbibent. The body 1 has a hole 2 on one of its ends or extremities for a traction thread 3, while the opposite end 4 is of a semicircular blunt shape, in the case ofFIGS. 1 to 6 The referred body 1 is coated or covered by a sheath 5 of solid vaseline (trademark) or jelly, which sheath is open on its end or extremity 6 and closed on the opposite end 7,
thislast also being semicircular and. rounded. The mentioned coating or sheath 5 is shorter than the body 1 at the end containing the hole 2 and the traction thread 3. The walls of the coating orsheath 5 maybe provided with borings 8 for aiding the passage of secretions towards the innerbocly 1. H r I 7 However, as shown in FIG. 5, this sheath or coating 5 preferrably has a continuous outer wall, without borin gs or openings. In this case, the passage of moisture and secretions towards the body 1 occurs when the sheath or coating is dissolved by body heat after application. U r I I i In another variation of said invention (FIG. 6), the means by which the moisture and secretions pass through to the absorbent middle body 1 are bbrings 9 which pass through both the sheath 5 and the body 1, thus forming transversal passages which go intothe pad. The rounded end or extremity 7, the nature of the material of the sheath or coating 5, and the extra flatness of the pad, thus make application or introduction of the pad relatively easy.
In another variation, corresponding to FIGS. 7 to 9, a rectangular pad which comprises a punched cellulose body 1, or celluloiddehydrated and pressed material shaped extra flat, is shown. The body 1 is positioned in the interior of a sheath of solid jelly or any jelly-like material 5. The sheath 5 is provided with a rounded end 7, and with an inlet or main bore for the passage of secretions towards the interior of the pad, which pad is highly imbibent or absorbent. The punch-pressed body 1 has a thread 11 sewn in a longitudinal manner, with loose stitches so as to allow for the expansion or swelling of the pad. The excess of thread 12 forms a traction thread loop.
In all these variations of the invention, the flat shape of the pad allows the packing of a great number of same in a minimum space, which also makes its carrying very easy.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
l. Improvements in pads for feminine use, of the type for internal application, said pads comprising a dehydrated pressed cellulose body of high moisture absorbent characteristics, said body being thin and flat, said cellulose body being positioned within the interior of an outer covering made of solid jelly-like material and shaped similar to the cellulose body, said covering being circular and rounded adjacent one end of said body, said solid jelly-like material dissolving by the thermic action of the human body, said covering acting as a lubricator for making the application of the pad easier aided at the same time by the flat shape of same, and means for the passage of moisture and secretions to the interior pressed cellulose body, said means including openings which go through the wall of said covering and through the interior cellulose body.
