Definitions

  • the present invention relates to a menstrual cup according to the preamble of claim 1.
  • menstrual cups are used to collect menstrual blood.
  • the well-known, bell-shaped menstrual cups made of thermoplastic elastomer (TPE) or silicone can be folded up and inserted into the vagina in this state. There the menstrual cup folds up again and sucks - albeit mostly unintentionally - with a slight vacuum. After the menstrual blood has been collected, it can be removed again by pulling on a pin which is arranged on the blunt tip opposite the receiving opening. After emptying and cleaning, menstrual cups can be reused, so that disposable sanitary towels or tampons can be avoided. This is one of the main reasons for the increasing popularity of menstrual cups against the background of increasing environmental awareness.
  • a menstrual cup which has a rotationally asymmetrical cup shape.
  • the present advantage of this embodiment is seen by the inventors that a rotationally asymmetrical shape is more suitable for a good fit of the menstrual cup, since it can be adapted to the anatomical conditions.
  • a single-use menstrual cup which comprises a shell for sealing the cervix and a pocket adjoining the shell, each made of a flexible material, which are individually manufactured and then connected to one another .
  • the pocket is used to collect menstrual fluid that has entered the pocket through the sealing cup.
  • This known menstrual cup is - in contrast to most known menstrual cups and also the menstrual cup of the present invention - not freely inserted into the vagina in order to lie circumferentially sealingly against the vaginal wall, but is placed with the edge of said shell directly on the cervix .
  • the shell also has two circumferential ribs; in addition, longitudinal ribs are provided along the shell and the pocket.
  • ribs are used to generate a resilient bias against the Ge cervix.
  • a return strap made of cotton as known from Tam pons, is provided, which runs through an eyelet provided in the center on the outside of the menstrual cup along the outside of the cup and cup and is used to pull out the menstrual cup.
  • US 2019/0083296 A1 discloses a menstrual cup which has the features of the preamble of claim 1.
  • the first end of a pulling element is arranged on the inside of the edge of the container wall and guided freely through the interior of the receiving space.
  • the second, free end of the tension element and in particular the special grip area are passed through an opening formed in the top of the container wall.
  • the advantages of the invention are particularly to be seen in the fact that the train element - contrary to US 2019/0083296 A1- does not run within the receiving space, but runs along the outside of the container wall of the Tas sen stressess and is guided by a guide device that does not Connects the recording room with the outside world. Rather, the guide device is designed without a fluid connection to the receiving space. Therefore, a possible leakage point for menstrual blood, as it could occur with the menstrual cup according to US 2019/0083296 A1, is avoided.
  • the fluid tightness particularly preferably also ensures that the pulling element does not come into contact with the menstrual blood either.
  • the menstrual cup according to the invention is or is placed in the vagina in such a way that its edge rests with its outer circumference on the vaginal wall.
  • the edge does not lie against the cervix in a sealing manner, but is placed further forward in the vagina and, with the outer circumference of the edge, seals the space behind the menstrual cup (in the direction of the cervix) opposite the space in front of the menstrual cup (in the direction of the vaginal opening).
  • the menstrual cup according to the invention does not come into contact with the cervix in the inserted state.
  • “Course of the tension element along the outside” of the cup body or its container wall is to be understood here as meaning that the tension element does not run through the receiving space.
  • the guide device provides a guide for the pulling element, the pulling force being able to act on the edge area of the cup body when pulling the grip area in order to deform the edge of the container wall.
  • the pulling force being able to act on the edge area of the cup body when pulling the grip area in order to deform the edge of the container wall.
  • some air from the outside between the vaginal wall and the deformed edge section can get into the space sealed off by the menstrual cup and thus cancel the sealing effect.
  • the menstrual cup can be pulled out of the vagina.
  • a user does not have to press the container wall of the menstrual cup laterally with one or more fingers in order to lift the edge off the vaginal wall so that air can penetrate into the sealed space between the menstrual cup and the cervix Under pressure cancels.
  • the guide device defines a location for the grip area so that it can easily be found and grasped by a user when the menstrual cup is in use.
  • the edge can be moved out of its holding or suction position when the grip area is pulled. It is assumed that when the edge is deformed outward, it is possible to prevent menstrual blood from sloshing out of the receiving space, since the container wall does not dip into the receiving space and thus into the blood.
  • the entry point for the air into the receiving space or the sealed space in the vagina is thereby advantageously shifted to the outside. After the air has flown into the space sealed by the menstrual cup through local deformation of its edge, the menstrual cup can be removed from the vagina.
  • the tension element is preferably elongated or elongated, i.e. it has a greater length than its width. It is preferably guided by the guide device with its first end on the said edge and preferably in the vicinity of its second end.
  • the pulling element here preferably extends at least over the entire height of the menstrual cup, i.e. from the edge along the container wall to the grip area, preferably on the shortest path from the edge to the tip of the cup body and preferably beyond. Before given, the length of the tension element is greater than the height of the cup body.
  • the tension element preferably runs freely along the container wall, preferably in the immediate vicinity or loosely in order not to be bulky and not to detract from the wearing comfort.
  • the term “free” here means that the tension element has no further fastening points with the cup body on its route along the container wall; the only loading fastening of the tension element on the cup body is rather preferably provided at the first end of the sen.
  • the Buchele element is guided by one or more guide elements of the guide device on the container wall. In the case of several such guide elements, these are preferably distributed along the outside of the container wall from the edge to the tip, advantageously along a line.
  • Said guide device is particularly preferably integrated in the cup body and is particularly preferably designed in one piece with it and in particular integrated into the container wall, always taking into account the fluid tightness towards the receiving space. It is also preferred if that Tension element is formed in one piece with the edge.
  • the term “in one piece” is to be understood as a material-uniform original shape, as can be realized, for example, by means of injection molding processes. In the case of a one-piece production, no parts are therefore glued or clamped together or the like after their production.
  • the guide device provided according to the invention particularly preferably comprises at least one through opening with an entry end and an exit end for the tension element.
  • the at least one fürgangsöff voltage here has no contact with the receiving space of the cup body; it is therefore fluid-tight with respect to the receiving space.
  • the tension element is particularly preferably freely guided through this through-opening, i.e. it can slide or move freely back and forth along the inner wall of the through-opening.
  • At least the exit end of the at least one through opening - and possibly also the entry end - is particularly preferably arranged in the region of the tip or preferably even integrated into the tip of the cup body.

  • the at least one said through opening is integrated into the container wall and runs in the container wall up to the tip of the cup body.
  • integrated into the container wall is to be understood as meaning that the through opening does not or hardly protrudes to the outside beyond the container wall, but is essentially embedded therein.
  • the through opening is then formed, for example, as a downward sloping channel in the container wall and ends in the region of the tip of the cup body. Due to such a course, small radii of curvature when deflecting the tension element at the inlet and outlet ends of the through opening are avoided, so that the tension element can be guided close to the container wall and the introduction of force via the tension element is optimized.
  • the guide device comprises a passage opening with an entry and an exit end for the pulling element, in which the passage opening extends in the direction of the tip of the cup body in the manner of a channel that is open or closed in cross section.

  • the version with the slot can be used, for example, to thread the tension element in the direction of the Be Schol terwand through the slot to prepare the menstrual cup for use. Threading out the tension element in the same way can be used to rinse the menstrual cup thoroughly under water and also to be able to effectively clean narrow-angled areas.
  • the edge is bead-shaped, the tension element being fastened with its first end to the bead-shaped edge, for example integrally formed thereon.
  • the bead-like configuration of the edge has the further advantage that it stabilizes the cup body.
  • the sealing of the menstrual cup against the vaginal wall can be optimally realized by the bead-shaped edge, since the outer circumference of the bead or the bead-shaped edge that protrudes laterally over the cup body rests on the vaginal wall.
  • the bead is preferably implemented by a circumferential material thickening during the manufacture of the menstrual cup.
  • said bead shape results from the edge of the container wall being folded over to the outside. If the container wall has a uniform thickness, for example, the edge in the folded-over area is twice as thick as the container wall.
  • the widened edge increases the sealing surface in relation to the vaginal wall and thus ensures that the menstrual cup is held securely.
  • the first end of the tension element can be connected to the edge in the case of a one-piece molding in the manner of a film hinge, the edge merging into the tension element in the direction of the tip. In this way it can be avoided that the tension element has to be folded over against the curvature of the edge, where it would lift off the cup body.
  • the menstrual cup preferably consists entirely of one piece, i.e. it is not produced by, for example, gluing, pressing, interlocking or screwing two or more parts together.
  • a one-piece menstrual cup (also sometimes referred to as “one-piece originally formed”) can be produced, for example, by means of an injection molding process.
  • it is also easily possible to use a compression molding process in which, for example, two halves of the menstrual cup are connected to one another - with thermal melting - and can then only be separated by destroying them.

Simultaneous gripping of the handle area and / or the section of the tension element between the handle area and through opening on the one hand and the handle section on the other hand is possible, please include. This reduces the risk of the fingers slipping off when pulling and the pulling force exerted can be used more efficiently and in a more controlled manner.
  • the at least one through opening which in turn has an entry and an exit end, is arranged between the base and the said handle section.
  • the grip area of the pulling element that runs through the through opening arranged in the tip like the grip section, is placed in the area of the tip, so that the grip area and grip section are both easily accessible for the user.
  • the pulling element is enlarged in cross section at its second end in such a way that it is not possible for this end to slip through the guide device counter to the pulling direction (i.e. away from the tip and down in the usage position of the menstrual cup).
  • the grip area thus forms a stop.
  • the grip area always remains on one side of the guide device during normal use, i.e. without excessive force being exerted, and can be gripped there again without the need for awkward handling to bring the grip area into its desired position.
  • the tension element is preferably designed to be flattened, with a flat side of the tension element running along the outside of the container wall. In this way, the tension element is only slightly bulky and is not perceived as annoying by the user.
  • the section of the tension element arranged between the first and second ends particularly preferably has a narrowed area which can slide through the guide device in both directions.
  • This narrowed area advantageously merges into a stop at least on the side facing away from the handle area, which comes to rest against the guide device when there is a large drawbar deflection. If the pulling element is pulled so hard that the stop hits the guide device, after the edge is deformed, the pulling force is additionally transmitted from the edge to the entire menstrual cup, so that the Menstrual cup can be detached from the vaginal wall and removed from the vagina more easily.
  • said stop is preferably implemented by a widened side edge contour.
  • the user receives immediate feedback from the stop that further pulling on the pulling element does not deform the edge any further. If the stop of the tension element comes to rest on the guide device, the user knows that the edge is now sufficiently raised and the menstrual cup can be removed. According to what has been said above, this can be done by further pulling on the pulling element, since this pulls the entire menstrual cup out of the vagina.
  • the grip area is advantageously designed not only for deforming said edge, but also for pulling out the entire menstrual cup from its position of use.
