专利说明:

FIELD OF THE INVENTION The invention relates to a menstrual cup. Such a cut is intended to be introduced into the vagina and be worn by a woman during the duration of her menstrual period to collect the menstrual flow.
For this purpose, the cup has a shape of small cup or cup with rounded edges, formed of elastic material.
Its opening in the upper part is usually delimited by a sealing ring, which seals the cup when it is in place in the vagina. Below the ring, the cut is generally constituted mainly by an inverted dome-shaped bottom part, which is connected to the sealing ring either directly or via a substantially cylindrical joining part. (hereinafter referred to as "cylindrical portion"). The flared bottom end usually ends at the bottom with a small rod to facilitate the removal of the cut.
BACKGROUND
The feminine hygiene market has changed a lot in recent years. Compared to sanitary tampons or periodic napkins, the menstrual cup appears as a solution more and more adapted to the expectations of modern women.
However, current cutting shapes leave much to be desired as to the ease of insertion and removal of the cut in the vagina. The insertion of a menstrual cup is usually done by first folding the cup on itself. The cup is then placed in the vagina, in which it unfolds and returns to its original shape. The elasticity of the cutting material causes the outer surface of its sealing ring to then be pressed against the vaginal wall, thereby allowing the ring to be relatively tight. The menstrual flow can then be collected in the inner cavity of the cup.
In general, a menstrual cup ends at the bottom with a small stem. The removal of the cut is done first by catching it by the stem. By pulling on this stem, you can first lower the cup to the opening of the vagina, then eventually remove the cup out of the vagina.
However, pulling on the rod to remove the cut creates a suction effect (or "suction" effect) very unpleasant, the edges of the cup coming to marry the vaginal wall. The object of the present invention is to overcome this difficulty and to provide a menstrual cup having a flared bottom portion, moderate cost, and whose withdrawal does not cause unpleasant sensations.
This objective is achieved by virtue of the fact that the menstrual cup comprises a plurality of non-convex gripping surfaces, distributed substantially axisymmetrically at least over said flared lower part, and configured to be gripped between fingers in order to facilitate removal of the chopped off.
For reasons of ergonomics, preferably the menstrual cup according to the invention has exactly either two gripping surfaces or three gripping surfaces.
Preferably, the lower portion has exactly two faces vis-à-vis one another, configured to be pinched between the thumb and the index finger.
As noted above, when a cut ends in a stem, pulling it to remove the cut is ineffective and may even be painful.
Thanks to the invention, the removal of the cut can be achieved without having to perform such traction on the rod.
In the case where a cut according to the invention comprises a rod, it should preferably serve only to guide the fingers towards the lower part of the cut, so that they can be easily placed on the gripping surfaces of the chopped off. It is possible to easily locate with the fingers the gripping faces of the cut due to their non-convex shape.
To allow removal of the cup out of the vagina, it has been found that advantageously pressure on the lower part of the cut allows to release or separate the cut of the walls of the vagina, and thus allow its removal.
In particular, the gripping surfaces can be used to turn the cut around its axis and thus take off the cut (or at least, dissociate it) from the walls of the vagina.
This possibility is enabled by the gripping surfaces, which offer a grip for the fingers and allow the transmission of a torque (while conversely it is very difficult to rotate a section whose lower part has a particular shape of revolution).
The removal of the cut is done by pressing the lower part of the cut, and possibly by rotating it; this operation or these operations allow to take off the cut of the vaginal wall; The cup can then be easily removed by pinching the grasping surfaces between the fingers and pulling the cup out of the vagina.
The fact that the gripping surfaces are non-convex, as defined above, means that at least in a sectional plane, the section of these surfaces forms a non-convex curve: for example a line segment, or a concave curve ( whose 'belly' is directed towards the inside of the cup).
The gripping surfaces may therefore be substantially flat surfaces; tiled surfaces (with the hollow directed towards the inside of the cup); hollow-shaped surfaces (the hollow may in particular have a curvature complementary to the shape of the fingers).
In one embodiment, the flared lower portion of the section is defined in part (and possibly substantially) by a surface of revolution, and the gripping surfaces are formed relatively recessed relative to said surface of revolution.
In one embodiment, each of the gripping surfaces is a contoured surface. By "profiled surface" is meant here a surface generated by the displacement of a generating curve along a line, or in a given direction of displacement.
The direction of movement may in particular be a direction perpendicular to the axis of the section.
For example, in one embodiment, the lower portion of the cup is defined in part by a surface of revolution, and the gripping surfaces are profiled in a substantially circumferential direction of movement, in a plane of horizontal section, with respect to this surface of revolution.
In one embodiment, the shaped shape has a substantially straight section. The generating curve is then substantially a line segment.
In one embodiment, in a plane perpendicular to an axis of the mid-height section of the gripping surfaces, the sum of the apex angles of the gripping surfaces is greater than 90 °. The gripping surfaces then have a large surface, which facilitates the holding of the cut and allows in particular to rotate it with the fingers more easily than if the gripping surfaces were smaller.
In one embodiment, said gripping surfaces are arranged below 70%, and preferably below 50%, of the height of an inner cavity of the section from a bottom of said cavity. Thus, the presence of the gripping surfaces does not substantially reduce the capacity of the inner cavity of the cut.
In one embodiment, at least a portion of said gripping surfaces have a pattern and / or grain.
A pattern here designates a particular relief of the face or faces that can be identified visually.
A grain here designates a slight relief that can be perceived to the touch but does not change the general shape of the surface or gripping surfaces.
The pattern and / or the grain makes it possible to distinguish the gripping surfaces from the rest of the lower portion of the section (of the portion of the lower part of the section which is complementary to the gripping surfaces); this remainder may in particular be smooth or substantially smooth, at least in comparison with the portion of the gripping surfaces having the pattern or grain.
Moreover, another disadvantage mentioned by the users who have tested a menstrual cup is the comfort of use, and in particular the presence of a prominent stem at the base of the cup.
To remedy this problem, advantageously, in one embodiment of the invention the lower part of the cup is devoid of rod. The absence of rod results in particular in that the thickness of the cut at the low point is less than one third of the maximum diameter of an internal cavity of the cut. Preferably, the thickness of the cut at the low point is even less than one fifth of the maximum diameter of the internal cavity of the cut.
In a manner known per se, the top of a menstrual cup is generally constituted by a sealing ring.
In one embodiment, the menstrual cup further comprises at least one pressure equalizing passage, arranged between the inside and the outside of the cup, the at least one passage opening outwardly below the cup. ring.
Also, when pressing on the gripping surfaces of the section to remove it, advantageously the section is removed from the vaginal wall at the outer orifice of at least one of said passage. A communication is then established by this passage between the inside and the outside of the cup: this communication immediately causes a balancing of the pressures between the inside and the outside of the cut, which facilitates the removal of the cut in removing any feeling of sucking.
Preferably, the outer orifice (s) of the pressure equalizing passage (s) are arranged (s) substantially in line with the one or more gripping surfaces. Indeed, when pressing on a gripping surface, the part of the cut that is the most detached from the vaginal wall is the portion of the cut that is located substantially to the right of the gripping surface (or surfaces of grasping) on which (s) we pressed. It is therefore in this portion of the outer surface of the section that it is most effective to provide the external orifices of the pressure balancing passages of the section.
Preferably, the external orifice (s) of the pressure equalizing passage (s) are located just below the sealing ring, for example at a distance below the lower edge of the ring less than half the radius. outside the ring.
In one embodiment, the sealing ring has a cylindrical outer surface over a height greater than 1 / 10th, and preferably 1 / 5th, of an outer radius of the ring.
Thus, this cylindrical outer surface forms a large surface intended to be in contact with the wall of the vagina, in contrast for example with a torus-shaped outer surface, which would allow only a contact along a line with the wall of the vagina. As a result, such a ring gives the cup a particularly great seal.
In one embodiment, the sealing ring has an upper surface inclined towards the inside of the cup, that is to say in the form of a funnel. This embodiment facilitates the entry of the menstrual flow into the cut and reduces the risk that part of the flow is not collected by it. BRIEF DESCRIPTION OF THE DRAWINGS The invention will be better understood and its advantages will appear better on reading the detailed description which follows, of embodiments shown by way of non-limiting examples. The description refers to the accompanying drawings, in which: - Figures 1 and 2 are two schematic views of front and side respectively of a menstrual cup according to a first embodiment of the invention; - Figures 3 and 4 are sections of the menstrual section of Figures 1 and 2, respectively in a meridian plane and in a transverse plane; FIG. 5 is a schematic perspective view of the menstrual cup of FIGS. 1 and 2; - Figures 6 and 7 are schematic views, respectively in perspective and in cross section, of a menstrual cup in a second embodiment of the invention; and - Figure 8 is a sectional view illustrating the removal of a menstrual cup. DETAILED DESCRIPTION OF THE INVENTION Referring to Figures 1-7, two menstrual cups 10 illustrating two embodiments of the invention will now be described.
These two sections are identical with the exception of certain characteristics which will be indicated later. Also, the identical or similar elements of these two sections have the same numerical references.
For the elements common to both cutting shapes, the following description is therefore common to both cutting shapes.
These two forms are illustrated respectively in Figures 1 to 5 (first embodiment) and in Figures 6 and 7 (second embodiment).
The menstrual cup 10 has a flared lower portion 20, a cylindrical portion 30 and a sealing ring 40.
An inner cavity 12 is formed inside the cup 10.
The section 10 has a generally rotational shape about an axis X. It is considered for simplicity the description that this axis X is vertical and that the opening of the cavity 12 is arranged upwardly.
The flared lower portion 20 is the portion of the cup in which the diameter of the inner cavity 12 of the cup decreases.
In the first embodiment (Fig.l to 5), the flared bottom portion 20 comprises two profiled gripping surfaces 22 and 24, axisymmetric and arranged vis-à-vis.
In the second embodiment (FIGS. 6 and 7), the flared bottom portion 20 comprises three profiled gripping surfaces 122, 124 and 126, which are axisymmetric and arranged facing each other.
The gripping surfaces (22,24; 122,124,126) are profiled surfaces.
In the embodiments shown, the gripping surfaces are profiled surfaces with substantially straight section.
Thus in the first embodiment, the gripping surfaces 22, 24 are generated by the displacement of a curve which substantially forms a line segment in a direction perpendicular to the section plane of FIG. 3. In FIG. represented the line D which can be considered as the straight line of this line segment for the surface 24.
In the embodiments presented, the gripping surfaces of the cut 10 are arranged only on the lower portion 20. They could possibly extend over the cylindrical portion 30.
These gripping surfaces extend in particular only up to a height less than 50% of the height H of the inner cavity 12 of the section. This height H is measured from the bottom of the section, and is 0% at the bottom of this cavity, and 100% at the top opening of the cavity (Fig.3).
The gripping surfaces occupy a relatively large area on the lower part 20, to allow the placement of the fingers and the gripping of the cut.
Thus, as seen in FIG. 4 or 7, in a section of the section along a transverse plane at mid-height of the gripping surfaces, the sum of the angles at the apex of gripping surfaces is greater than 90 °.
The gripping surfaces have a visual and tactile appearance different from the rest of the outer surface of the lower part 20.
Thus in the first embodiment, the gripping surfaces 22 and 24 have a grain on grained surfaces 28. This grain is conventionally obtained by grained surfaces of complementary shape, provided in the manufacturing molds of the section 10.
The gripping surfaces 22 and 24 are fully grained in the surfaces 28, with the exception of reservations 29. These reservations 29 are the portions of the gripping surface 22 and 24 that are not grained, unlike the rest of the surfaces 22 and 24. The reservations 29 thus remain smooth as the remainder of the outer surface of the cup 10. The alternation of grained surfaces and smooth surfaces (surfaces 28/29) forms a pattern that allows tactile recognition. and / or visual gripping surfaces 22 and 24.
In the second embodiment, the gripping surfaces 122, 124, 126 are entirely grained, and do not include smooth reservations.
Advantageously, the presence of the gripping surfaces in the lower part of the cup 10 makes the rod totally useless.
In the first embodiment, the bottom of the cup 10 has just a small peak 25, in the form of a peak. This allows to locate the end of the cut and facilitates the placement of the fingers on the gripping surfaces.
The upper part of the cup 10, in the vicinity of the sealing ring 40, comprises pressure balancing passages 45. These passages have external orifices (also marked 45) which are located generally to the right of the gripping surfaces. 22, 24 (as can be seen in particular in Figure 2). These passages are passages that pass through the wall of the section and thus connect the internal cavity 12 of the section on the outside thereof. The sealing ring has a cylindrical outer surface 41. This surface extends vertically (along the X axis) along a certain height. This height is greater than 1 / 10th of the outer radius R of the ring 40 (FIG. 3).
The cylindrical outer surface 41 is intended to improve the seal by increasing the contact area between the upper and outer edge of the cup and the wall of the vagina; and maintain sufficient rigidity, both when folding and deploying the cut once installed. The ring 40 further has an upper surface 42 inclined towards the inside of the cup. The shape of this surface 42 is represented by the arrow A in FIG. 3. The upper surface 42 thus has a downward slope towards the inside of the section, since the edge formed at the upper end of the outer cylindrical surface 41 until the junction of the ring 40 with the internal cavity 12 of the section.
Due to the inward (radially) inclination of this surface, a menstrual flow which would be on this upper surface of the ring 40 would flow inside, and not outside, the cavity 12 of the cup.
FIG. 8 schematically shows a removal operation of the section 10.
To remove it, it is necessary to pinch the lower part of the cut between the fingers. The cup 10 can be rotated about its axis to separate it from the vagina; The cup is then pulled down and extracted outside the vagina.
Although the present invention has been described with reference to specific exemplary embodiments, it is obvious that various modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. In addition, individual features of the various embodiments mentioned can be combined in additional embodiments. Therefore, the description and drawings should be considered in an illustrative rather than restrictive sense.
