    DESCRIPTION
    Container for menstrual retention and emptying.
    The Field of Technology found as the most repeated for this type of device is the A61F 5/44
    STATE OF THE PREVIOUS TECHNIQUE
    Various types of deposits, receptacles or menstrual containers have developed over time, so in US1743733 an external menstrual collection system is designed, and in US2182702 a receptacle collects the liquid directly from the outlet of the matrix, which It goes to a tank and it has an external stopcock at the end of a tube for emptying.
    US5827248 is more evolved and similar in some respects to the current invention. The vessel is cup-shaped and has a drain pipe at its outlet with various valve variants, but none like the one presented.
    EXPLANATION OF THE INVENTION
    There are basically two types of containers (1), one in the form of a cup (2) and the other in the form of a low cylinder, or thick disk, or flat cup (21). They have a drainage system through a tube (3) that can be operated at will, being especially suitable for part-time emptying without having to take out the entire container.
    The novel inventions presented are improvements to existing devices and basically consist of:
    The drain tube (3) has the same inner diameter, but with parts of different wall thicknesses (6), (7), (8), (9) whose larger diameters protrude outside. The first section (6) of the drain pipe (3) is at the exit of the hole (5) and is of normal thickness or greater than normal. The second section (7), having the thickness of the wall of the thin tube, thinner than the previous one, allows easy bending in it because it is weaker between the attached sections (6) and (8), which in this way blind (12) through its middle zone, preventing the passage of liquid with what acts as a valve. This bending occurs below an angle between branches of said second section (7) of about 80 °. To make the bending, it is pushed up by the third part (8) of the tube (3), which
    5

    It is of normal thickness and less flexible, because it has a greater wall thickness than the second section (7). The fourth section (9) is of thin wall thickness and very flexible. To keep the tube bent upwards, the end part of the tube (9), where it has the exit hole (10), and / or the final part of the third part (8), can rest directly on the vaginal wall that makes that it be maintained in this position since the middle part (8) of the thicker wall of the tube (3) would need a greater force to remove it from this position than that exerted by the finest wall part (7). This force is carried out by the user by stretching said third part (8) downwards and having certain flexibility yields and allows the whole tube (3) to be placed in a straight or extended position, especially at a 180 ° flat angle between branches of the second section (7), and thus carry out the emptying. To put the tube (3) back into the position of use of the container (1), the reverse operation is carried out, pushing the second section (8) upwards, thereby bending the tube through its second thin-walled part (7) , blinding the passage of the liquid.
    The essence of the operation of the drain tube (3) as a valve, lies in the second section of thin wall (7) and in the third section (8) of normal wall, so the first (6) and last (9) sections ) may or may not exist. In the case that the first section (6) does not exist, the second section (7) starts directly from the base of the cup (2). Alternatively, some drainage tube fastening systems (3) are presented in the folded position, to the container itself (1), such as: the introduction of the ends (9) and / or (8) under a skirt or a concentric fin (17) of the cup (2), and which can be hung directly from the upper edge (13) of the container, or said fin protruding halfway from the side wall of the cup (2), in an area below the edge superior (13). Similar case is the introduction of the ends (9) and / or (8) of the drain tube (3) of the low cylinder or flat cup (21) into the hole defined by the disc (22), the membrane (24), the lower ring (25) and the drain tube (3). There is also another solution for securing said end (9) and / or (8) to the cup (2), with a cavity (20) which is a deformation inward of the side wall of the cup (2), in that the surface outside the cup is cylindrical where it allows to fully or partially accommodate the end of the drain tube (9) and / or (8) when it is in the folded position. Said cavity (20) has an open cylindrical shape and depending on its depth it can partially or totally accommodate the end of the drain tube (9) and / or (8) to which it fits. If it is fully housed, the end of the pressure tube is inserted through a groove having said cylindrical surface.

    Thus, the fastening of the folded drain tube (3) can be in any position if it is supported directly on the vaginal wall, or inside the hollow (19) that defines a concentric fin to the cup, or in the hollow (26) of a cylinder-shaped container (1) with a diameter of its base greater than its height, reminiscent of the shape of a large tablet. Not so, the solution of the cavity (20) in the wall of the cup (2) that is discretionary, that is, can only be placed in one cavity, or several, but not in any position. Similarly, discretionary gaps could be made under the fins or in a partial fin (17), both in the cup (2) and in a flat cup (21).
    A grid (11) above the outlet hole (5) acts as a filter for possible lumps so that the drain tube (3) cannot be blocked.
    The vacuum effect that users can experience when extracting a cup is usually broken by the entry of air through small holes made in the side wall of the cup, just below the ring corresponding to the top edge of the cup. These small holes are inclined with respect to the surfaces of the side wall of the cup and are usually between 1 and 2 mm in diameter. In the case of the invention, they could still exist, but they make no sense if the cup (2) is inserted with the drain tube (3) open (extended without bending), which communicates the atmospheric pressure with the indoor air. Also, in the extraction, if the bending is removed and the drainage tube (3) is extended, its contents are emptied and then the complete extraction of the container (1) is carried out with said tube (3) open there will be no vacuum effect.
    This invention does not seem to exist for these devices, nor does the fastening systems of the tube bent upwards to keep the passage of the liquid blinded. Said system makes the container (1) with drainage and valve system very simple in design, materials and manufacturing.
    One or more notches (14) in the inner part of the ring of the upper edge (13) of the cup (2), makes the wall thickness smaller in these notches, which causes its weakening, and any bending effort will be smaller, besides being less bulky and more compact. Four notches (14) diametrically opposed and equidistant from each other, means that, for one of the most usual folds of the cup, less force has to be applied than in the same cup without notches, and that said folding results in less volume and by So make your entry easier.

    A double ring (15) of the upper part of the cup is intended to improve the tightness of possible drop losses. This double seal (15) has a gap (16) between rings. This space (16) can be a membrane or the wall of the cup itself.
    A container (1) in the form of a flat cup (21) or low cylinder is hollow below. Its upper base is a disc (22) with a hole (5) from which the drain pipe (3) hangs, which when in a folded position due to its thinner wall area (7) acts as a valve, closing the bleeding path which temporarily accumulates in the vaginal cavity itself, until it is emptied by the drain tube (3).
    The drain tube (3) when folded allows its end (9) and / or (8) to be anchored in the recess (26) formed under the disk (22), the membrane walls (24) and the lower ring ( 25). Half-day emptying, without removing said flat cup, is achieved by applying a small force down on the third section (8) of the tube, so that the end (9) and / or (8) will leave the hole ( 26) to put the tube extended and thus empty the container. To continue with its use, the reverse operation is performed by applying an upward force on the third section (8) so that it bends by its second section (7) of thinner wall and overcoming the resistance so that the end again (9) and / or (8) between the hole (26) under the disk (22).
    Similarly, the container (1) in the form of a flat cup (21) or low cylinder can have the disc (22) located halfway down the cylinder. In the down position, the disc (22) would be the bottom base of the cylinder and would be uncovered from above. The hole (5) of the disc (22) from which the drain tube (3) hangs, has a first section (6) of normal wall thickness, a second section of thin wall thickness (7), a third section ( 8) of normal wall thickness and a fourth section (9) of thin wall thickness, in addition, said lower disk has a rounded edge from which a membrane (24) or cylinder wall ends up in a ring of similar diameter at the edge of the lower disc, thus forming a hollow above that collects all or part of the menstrual fluid, when the drain tube (3) is bent and does not let the liquid pass. In this case the end of the drain tube (3) rests directly on the vaginal wall. The menstrual flow can be emptied by the drain tube (3) when it is stretched from its position by its third section (8) and said tube is extended.
    The flat cup shape (21) is the minimum expression of a container with a drain tube (3) to retain menstruation.

    There may also be possible combinations between the above forms. The advantages of some of these inventions can be summarized in ease of introduction, safety of operation, emptying part-time without the need to remove the entire container, simplicity of forms and materials, and therefore economic.
    BRIEF DESCRIPTION OF THE DRAWINGS
    Figure 1 shows an elevation section of a cup-shaped container (1) (2) with the drain tube (3) at its bottom. In the section you can see the wall thicknesses (4) of the cup (2), as well as those of the drain pipe (3). The hole (5) communicates the bottom of the cup (2) with the drain tube (3) that has its outlet (10). A grid (11) integrated in the bottom of the cup acts as a lump filter. The first section (6) of the drain tube (3) having a normal wall thickness compared to the second section (7) having a thin wall thickness. It is followed by the third section (8) of normal thickness and a fourth section of the thin wall end (9).
    The upper edge (13) of the cup (2) is like a ring of approximately circular section and having a notch (14) marked.
    Figure 2 shows a section of the bottom of the cup (2) and the beginning of the drain tube (3) when it is bent upwards by its second section (7), which is the weak part because it has a thin wall thickness, with the blinding zone (12), which is followed by the third section (8) of the drain pipe (3).
    In figure 3 the upper edge (13) of the cup is drawn with a notch (14).
    Figure 4 shows a section of a cup (2) with double ring (15) at its upper edge, with a gap between rings (16).
    Figure 5 is a section of a cup (2) truncated from below, with a skirt or a concentric fin (17) attached to the upper edge (13) of the cup, this fin has a lower edge (18), which defines a gap (19) between the fin and the outer wall of the cup (2). In this hole (19) the end of the drain tube (3) can be introduced when it is bent. The shape of the side walls of said cup (2) is a straight cone.

    In Figure 6 a section of a cup (2) having a concavity (20) is drawn on the side wall to fully or partially accommodate the end of the drain tube (3) when it is bent upwards. The lower part of the figure corresponds to a plan view of a part of the inside of the cup (2) where the upper edge (13) and the side wall of the cup (2) deformed inwardly by the cavity ( twenty).
    Figure 7 is an elevation view of a container (1) that is an object of symmetrical revolution with respect to its central axis and has a low cylindrical shape (21) reminiscent of a thick disk or a large, hollow round tablet below , from which the drain pipe (3) hangs. It has an upper disc (22) somewhat inclined towards the hole (5), from whose edges the drain tube (3) with its different parts of different thicknesses (6), (7), and (8). From the edge of the upper disc (23) hangs a membrane (24) whose lower end is a ring (25). This defines a gap (26) between the disc, the membrane, the ring and the drain tube, which will be where the end of the drain tube (3) is housed when it is bent.
    DETAILED EXHIBITION OF AN EMBODIMENT
    Without being limiting, a specific embodiment of the present invention, a container for menstrual retention and emptying, is set forth below.
    The container (1) is shaped like a cup (2) from whose base the drain tube (3) communicates through the hole (5) inside the cup (2) with the outside through the outlet hole (10 ).
    The drain tube (3) does not have a first section or is very small, but directly has the second section (7) with a thin wall that is attached to the lower end of the cup. Said section (7) has a thin wall thickness that gives a lot of flexibility in this area. It is followed by a middle or third section (8) of greater wall thickness of the tube than the previous one, which ends in the fourth section (9) with a thin wall thickness similar to that of the second section (7).
    In use, the tube (3) bends down the weak part (7) by pushing it up the middle part (8), the tube being blinded in this area (12). This closes the passage of the liquid and the end (9) is placed under the upper edge (13) of the cup, between the side wall of the cup and the vaginal wall, which is anchored in this position.
    One or more strips above the hole act as a grid (11), in order to filter the liquid and retain the lumps.
    The shape of the side walls of the cup (2) is rather conical or parabolic and rather slender, topped at its upper edge (13) by a solid inner ring of the same cup material and of a certain thickness.
    The upper edge (13) of the cup (2) has four notches (14) diametrically opposite two to two and equidistant from each other that will serve to improve the folding for the introduction of said cup (2).
