DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0027] FIG. 1 illustrates a container for cleaning and sterilizing menstrual cups in an isometric view.

[0028] A container is suitable for cleaning and sterilizing products of feminine hygiene such as a menstrual cup shown in FIGS. 9 and 10 which is made of elastic material and has a bell-shaped portion 27 for collecting menses and gripping means 28 at a tapered bottom of the bell-shaped portion 27, preferably in the form of a stem, for insertion and removal during menstrual cycle.

[0029] A container in accordance with the preferred embodiment of the present invention comprises a vessel 1 with an open-top closed tightly with a lid 5. The vessel 1 has a bottom 8 and side walls defining an inner cavity 25 for holding a cleaning liquid and for receiving a menstrual cup.

[0030] The container is made of elastic materials suitable for medical contact and being subjected to heat in a microwave oven such as silicone, polymer or co-polymer plastics materials. It is to be understood that all the container can be made of elastic and flexible materials or the container is partly elastic and partly rigid.

[0031] Referring to FIG. 2 and FIG. 8 illustrating the container in exploded view and in cross-section respectively, the container may comprise a vessel 1, discharging means, a brush 26 arranged in a cavity 25, a flexible string 6, a central ring 3, a clamp ring 4, a lid 5 with holding means 16 and tactile and/or visible markers 7.

[0032] The lid 5 is reversible so that it can be fitted on the open-top in two mounting positions and further comprises holding means 16 for connecting the menstrual cup with the gripping means 28. The first mounting position is with the holding means 16 directed towards the inner cavity 25 such that, when attached to the lid 5, the menstrual cup projects at least partially into the inner cavity 25. The second mounting position is with the lid 5 reversed and the holding means 16 directed away from the inner cavity 25 such that the menstrual cup projects outwardly.

[0033] The holding means 16 can have the form of three projections. The stem 28 is pinched between said projections resulting in the menstrual cup being retained firmly in place.

[0034] The clamp ring 4 with a portion at least partially enclosing the holding means 16 is attached to the lid 5 by screwing such that as the clamp ring 4 screws on the lid 5 said portion tightens up the stem 28 and retains the menstrual cup firmly in place. The upper portion of the clamp ring 4 comprises grooves and recesses allowing the user to screw the clamp ring 4 on the lid 5 and to secure the clamp ring 4 on the holding means 16. On the outside of the walls of the lid 5 and on the inside of the bottom part of the clamp ring 4 mating threads 18 are provided enabling these two parts to connect each other.

[0035] On the inside of the lid 5 and on the outside of the central ring 3 there are provided mating threads 17 so as to connect and seal these two elements together. Compatible chamfers are located at the beginning of the each thread 17 to ease the positioning of said elements and to start screwing. A circular bulge arranged in the lid 5 creates a slot between the bulge and the thread 17 of the lid 5 where a rim 15 of the vessel 1 and the central ring 3 can slot in. It is meant to complete the sealing process of the vessel 1 while screwing the lid 5 to the central ring 3. The clamp ring 4 is connected by screwing clockwise on the lid 5 and around the holding means 16. By screwing, the inner walls of the clamp ring 4 come into contact with the outer walls of the holding means 16 thereby reducing a diameter of a space available at the center of the holding means 16 and further resulting in clamping the stem 28 between the holding means 16 to firmly retain the menstrual cup as can be seen in FIG. 9.

[0036] The lid 5 has a protruding portion 20 on the side opposite to the side with the holding means 16. Said protruding portion 20 enables the lid 5 to be retained in the second mounting position. On the circumference of the protruding portion 20 bumps and recesses 22 are provided that serve a function of releasing the air from the vessel 1 and ensure against an air tight seal which could result in ejecting the lid 5 if the user unintentionally pressed on the vessel 1. Once the container is opened and the lid 5 is reversed (see FIG. 10), the lid 5 is plugged by pressure and rotation in the second mounting position so as to manipulate the container with the menstrual cup attached it with ease (see FIG. 9). The bumps 22 create a pressure on the flexible vessel 1 which fastens the lid 5. As can be seen in FIG. 7 a visible marker 23 saying “Do not use for drinking” indicates that the container should not be used as a drinking vessel due to bacteriological contamination. This prevents any misuse by accidental bystanders who may have found the container.

[0037] As can be seen in FIG. 3, a visible marker 19 is provided on the outside of the central ring 3 to indicate the appropriate direction of rotation to open the container.

[0038] The upper part of the vessel 1 is topped with the rim 15 which connects the vessel 1 to the central ring 3. The circular rim 15 also serves to firmly maintain the vessel 1 and the central ring 3 in place and to create a waterproof seal fully completed by an additional bulge on the rim 15 in order to apply pressure to the rim 15 and seal it when closing the container with the lid 5. Moreover, it creates a gradual pressure and gives the feeling of locking. The lid 5 and the central ring 3 are connected together by screwing in order to prevent against leakage.

[0039] The vessel 1 has the discharging means allowing the cleaning liquid and menses to be expelled after cleaning process. The discharging means comprises a bottleneck 9 arranged on the outside of the vessel 1, a spout 10, and a cap 2 with a rod 12 that enters the spout 10 and closes it tightly. The bottleneck 9 creates a waterproof seal with the cap 2. The spout 10 permits to drain off the water and thick organic materials after cleaning. The cap 2 is provided for the purpose of closing the flexible vessel at the bottleneck 9 thanks to the rod 12 entering the spout 10. A circular part located at the base of said rod 12 and a dedicated groove 11 in the bottleneck 9 help to lock them together. Moreover, the angles of the extremity of the rod 12 and narrower inner walls of the bottleneck (see detail section A-A, FIG. 8) allow to maintain the rod 12 inside once it has passed said narrower walls so it can be pulled outwards to release the cap 2 and thus free the spout 10. The flexibility of the vessel 1 allows the cap to enter the bottleneck 9 with small pressure. Additional securing means may be provided to prevent the cap 2 from unwanted and accidental unlocking. For this purpose, close to the bottleneck 9, a protruding stripe 14 with a pinch 24 is provided. The pinch 24 enters an opening 13 in a portion of the cap 2 and presses the cap 2 against the vessel 1 thereby securing the cap 1 fitted in the spout 10.

[0040] The brush 26 is arranged in the inner cavity 25 of the vessel 1 at the extremity of the bottom 8. The brush 26 extends into the bell-shaped portion 27 and is in contact or at close proximity with said portion when the lid 5 is in the first mounting position with the menstrual cup attached to it.

[0041] The vessel 1 may comprise visible and/or tactile markers, for instance two circular markers 7 as shown in FIG. 5 indicating where to squeeze the vessel 1 using fingers in order to clean the menstrual cup with the help of the brush 26. When squeezed, the brush 26 comes into contact with inner walls of the bell-shaped portion 27 and cleans the menstrual cup. An additional marker may be provided on the outside of the bottom 8 of the vessel 1 indicating where to press with a finger so as the brush 26 can enter into contact with the bell-shaped portion 27 in order to clean it.

[0042] The flexible string 6 is connected to the central ring 3 through an opening formed in the central ring 3, on the opposite side of the bottleneck 9 with the cap 2. The opening has a slot shape although other shapes are also possible. Said flexible string 6 enables users to hold and manipulate the container securely upon the process of cleaning and sterilization.

[0043] Although the embodiment of the present invention illustrated in the drawings comprises additional elements like a central ring, a clamp ring, a brush, etc., it would be apparent for the person skilled in the art that these elements are not necessary for the invention to solve the objective technical problem and shall not limit the scope of protection given in the appended claims.

[0044] During the process of cleaning, the container contains the menstrual cup attached to the lid 5 along with the cleaning liquid, for instance water. The menstrual cup is cleaned by squeezing, hand-shaking or pressing the markers 7 by fingers.

[0045] Sterilization must happen in a microwave oven. The level of water required for smooth and effective cleaning is indicated by the extremity of the cleaning brush 26 which normally does not exceed 60 mls. For the sterilization, the level of water can be higher in order to fully submerge the menstrual cup.

[0046] For cleaning, a quantity of water is introduced in the cavity 25 of the vessel 1 up to the level of the brush 26. Then, the lid is 5 plugged upside-down on the central ring 3 that is in the second mounting position (see FIG. 10). Afterwards, the emptied menstrual cup is attached to the holding means 16 by pinching the stem 28 between the projections. Then, the user tightens the stem 28 by rotating clockwise the clamp ring 4 until the menstrual cup is firmly held. By screwing the clamp ring 4 causes the projections to bend inwards and to press against the stem 28. The lid 5 is subsequently reversed and fitted in the first mounting position with the menstrual cup inserted head down inside the vessel 1 and submerged in the water. The lid 5 is screwed on the central ring 3 to create a waterproof sealing. During the manipulation, the user operates the flexible vessel 1 by squeezing on the circular markers 7, using the thumb to press the bottom 8 to clean the inner part of the bell-shaper portion 27 with the brush 26 or by simply shaking the container.

[0047] After completing the procedure of cleaning, the cap 2 closing the spout 10 must be lifted and pulled outward thanks to the recess 21 (see FIG. 5) formed in the bottleneck 9 allowing the user to unlock the cap 2 with a finger or a nail. Beforehand, the container should be held with the cap 2 upward to avoid any used water to leak through the opened spout 10. The cleaning liquid containing menses must be expelled through the spout 10. Pressure can be applied on the flexible vessel 1 to speed up the expulsion of content and any remaining thick organic materials. When the container is empty, the cap 2 can be fitted again in the spout 10 and the lid 5 put upside down in the second mounting position. The user can safely dry the menstrual cup without having to hold it by hand (see FIG. 10).

[0048] For sterilization, the process remains the same and comprises steps of filling up the vessel 1 with water, connecting the menstrual cup to the lid 5, closing the container with the lid 5 being in the first mounting position, placing the container into the microwave oven. The cap 2 must be pulled out so as steam or boiling water can expel trough the spout 10. During the microwave process, steam produced by evaporation of the water within the container passes through the spout 10 and over the menstrual cup. On completion of the microwave cycle, residue water present in the container can simply be removed by inverting or partially inverting the container to allow drops to flow out. In addition, a dry and clean cloth can be used to absorb remaining liquid or organic materials. It is also advised to fully open and unscrew the clamp ring 4 to clean and dry the void space in between the holding means 16 and the clamp ring 4.
