Abstract

The invention relates to a cosmetic unit (1) having a bottle (2) for storing a cosmetic product and a cap (3) for sealingly closing the bottle (2), at which an applicator (26) is preferably fixed, wherein the bottle (2) and the closing device each carry a permanent magnet (12; 13), characterized in that the permanent magnets (12; 13) are obtained and supported in such a way that one of the permanent magnets (12; 13) can be moved from a first position, in which it attracts the other permanent magnet (12; 13), into a second position, in which it repels the other permanent magnet (12; 13).

Description

Cosmetic container with special locking device

Technical Field

The invention relates to a cosmetic container with a special closure device according to the features of the preamble of claim 1.

Background

Cosmetic containers with a lid which closes off this cosmetic container and holds the applicator by means of a rod are known in the most different shapes. In these cosmetic containers, it is very important that the lid can be safely held in its closed position. Since it is important to prevent the cosmetic container from being opened accidentally and the contents of the cosmetic container from flowing into, for example, a user's handbag.

For this purpose, a screw lock is preferred. These screw-locking means allow the cap to be screwed firmly onto the container neck. The screw locking devices usually have a thread which is self-locking, i.e. cannot be accidentally released.

However, problems can also arise here, for example, because the cap is not screwed sufficiently firmly onto the bottle neck inadvertently. Dire outflow can also occur.

As an alternative, detent locks have been proposed for this purpose, which are stopped by an audible click and thus indicate to the user that the closure is properly performed.

However, these detent locks are either very expensive to construct. If not, they mostly have the disadvantage that opening them requires rather some force. If the closure device should accidentally fall out of the bottle neck, this can result in an inadvertent, sudden movement when opening. Thereby possibly causing the contents to come out accidentally.

Magnetic latching devices have also been designed as a third alternative solution. For this purpose, magnets are used, which hold the lid permanently firmly on the cosmetic container. This results in an automatic forced locking of the cosmetic container, since the lid must be attracted sufficiently strongly by magnetism.

However, the problem of the rather demanding opening is not rare in these alternative solutions with the aid of magnets. This in turn can lead to terrible accidental sudden movements, in which a part of the contents of the cosmetic container can be accidentally discharged.

Disclosure of Invention

Against this background, the object of the invention is to create a closure device which, on the one hand, forces the lid to completely close the cosmetic container. On the other hand, the required closure should also ensure that, when it is opened, no sudden movements occur which could lead to an accidental emergence of the cosmetic product.

The solution according to the invention is achieved with the features of claim 1.

A cosmetic unit with a bottle and a cap for storing a cosmetic product is therefore proposed.

The applicator is preferably fixed to the cap. The cap then serves as a handle for manipulating the applicator secured thereto. In any event, the cap serves to sealingly close the bottle.

Provision is made here for the bottle to carry a first permanent magnet and for the locking device to carry a second permanent magnet. According to the invention, the permanent magnets are obtained and supported such that one of the permanent magnets can be moved from a first position in which it attracts the other permanent magnets to a second position in which it repels the other permanent magnets. In this case, the movement of the permanent magnet can generally take place without the cap moving relative to the bottle.

With the invention it is achieved that no force or significant force has to be applied at the lid in order to open the lid in order to detach the lid from the container and to conduct the opening process. In particular, no significant tensile forces are required. Sudden, unintentional movements are thus avoided, which otherwise occur in magnetic latching devices at the moment when the magnetic parts lift from each other, so that an air gap is created, which leads to an unexpectedly rapid collapse of the magnetic force.

It is particularly preferred that one of the permanent magnets is supported such that it can be moved from its first position into its second position by a rotational movement. The rotational movement for moving the magnets that are attracted to each other is associated with the smallest possible force consumption. It also excludes the user from being frightened by an accidental concession of magnetic force (Nachgeben) while turning and then sudden movements do not occur autonomously.

Ideally, the cosmetic unit carries a resetting means which destabilizes the second position in the sense that the associated permanent magnet automatically returns from its second position into its first position as soon as the user no longer exerts a force forcing the permanent magnet into its second position.

This ensures that, when the lid is completely lifted off and away from the bottle with its permanent magnet, the movable permanent magnet also returns again into its initial position, so that no resetting action is initiated with its permanent magnet whatsoever.

It is particularly preferred here that the resetting means is a third permanent magnet which magnetically repels the movable permanent magnet into its second position in such a way that it is pressed back into its first position as soon as the user no longer exerts a sufficient force.

The return means may alternatively be a spring element and preferably a torsion spring element. This resetting means is designed in such a way that it presses the permanent magnet, which is moved into its second position, back into its first position as soon as the user no longer exerts sufficient force.

The design is preferably such that the first permanent magnet is firmly connected to the lid and the third permanent magnet is firmly connected to the bottle. The first and second permanent magnets are thus immovable and can only move with the lid or bottle where they are fixed. The second permanent magnet is sandwich-shaped and is arranged rotatably between the first permanent magnet and the third permanent magnet.

Ideally, the second permanent magnet is firmly connected to the preferably tubular actuating collar or actuating ring and is accommodated largely (usually completely) within it. This actuating collar is mounted on the neck of the bottle in a rotationally movable manner. The steering collar preferably also houses the third permanent magnet (if present) within its interior, typically completely within its interior.

The actuating collar preferably has at least one stop means. The actuating collar can be locked on the neck of the bottle in a rotationally movable manner by means of this locking means. This greatly simplifies installation.

Ideally, the cosmetic unit has at least one positioning means. The positioning device is constructed as follows: the cap is always oriented when it is moved onto the neck of the cosmetic bottle such that when the cap reaches its fully closed position, the poles of the first permanent magnet of the cap are in a particular position relative to the poles of the second permanent magnet of the bottle.

The positioning means are simultaneously or alternatively responsible for bringing the pole of the first permanent magnet of the cover in a specific position with respect to the pole of the third permanent magnet in the undeflected position when the cover reaches its fully closed position.

Detailed Description

The best overview of the invention is obtained with the aid of example 1. This embodiment is shown most clearly in figures 1, 2 and 3.

As one can see with the aid of fig. 1, the cosmetic unit 1 is formed by a bottle 2. The bottle 2 is filled with a cosmetic stock 6. The cosmetic inventory preferably relates to mascara or eyeliner.

Furthermore, the cosmetic unit 1 comprises a cover 3. The cover 3 carries the rod 4 in most cases. The rod 4 is preferably connected integrally or monolithically with the cover 3. This rod 4 itself can be turned integrally into an applicator 26. Applicator 26 is only schematically shown here. The rod 4 alternatively has a coupling element 5 shown here for coupling the applicator 26.

As can be seen, when the lid 3 is on the bottle 2 in its fully closed position, the stem projects into the cosmetic stock 6 with the applicator 26 carried by it.

The cosmetic unit typically has a scraper 7. The scraper 7 is inserted into the neck 8 of the bottle 2 and is typically fixed there by a stop. The scraper 7 is used to keep the applicator 26 and the stem 4 holding it free of excess cosmetic product once the cap is removed from the bottle and the stem with the applicator 26 is pulled through the scraper 7. In this way, for example, uncontrolled dripping of excess cosmetic product is prevented. Applicator 26 is loaded with makeup only after being pulled out to the extent that it works well with the applicator.

As is also clear from fig. 1, the cover 3 may also comprise a decorative sleeve or cover 9, if appropriate. The decorative sleeve gives the cover a finished appearance outward. It makes the internal structure of the cap designed according to the technical specifications invisible to the eyes of the user.

If the cover 3 is viewed in more detail with the aid of fig. 2, it is confirmed that the cover has a base 10 in this preferred embodiment. The base 10 has the form of a ring-groove-shaped recess. The base 10 carries a stop element 11. The stop element 11 is configured here in the form of a circumferential annular shoulder. The side walls of the base 10 are sufficiently thin to enable the first permanent magnet 12 to be tensioned into the annular groove forming the base 10. The side walls of the base 10 are elastically expanded here.

As can be seen, the first permanent magnet 12 is preferably designed here as a completely closed ring in the circumferential direction. This ring forms a passage in its centre for the bottle neck 8. The first permanent magnet 12 is firmly connected to the cover 3. The first permanent magnet is thus not rotated relative to the cover into a position different from the position occupied by the cover.

The third permanent magnet 13 is arranged directly below the first permanent magnet 12. The third permanent magnet 13 is also configured as a ring. The third permanent magnet also constitutes a passage in the center for the bottle neck 8. The third permanent magnet is preferably also completely closed in the circumferential direction.

The third permanent magnet 13 is connected in a rotationally fixed manner to the actuating collar 14.

The operating collar 14 is itself rotatably supported by the neck 8 of the bottle 2. For this purpose, the neck 8 of the bottle preferably has an expanded neck section 15. The diameter of the expanded neck section 15 is greater than the diameter of the immediately upper portion of the neck. While it is smaller than the diameter of the belly 16.

It can be clearly seen with the aid of fig. 3 that the neck of the bottle, or more precisely the expanded neck section 15 of the neck of the bottle, carries a stop element 17. This stop element 17 serves to rotatably stop the actuating collar 14. The actuating collar 14 is secured by this stop element 17 in the direction of the container longitudinal axis L.

Ideally, the neck portion may form a stop lug or one or more partial stop elements 19. The stop element or elements additionally prevent the third permanent magnet from moving in the direction of the longitudinal axis L of the cosmetic unit.

The one or more stop elements 19 are designed such that they are radially offset in such a way that the third permanent magnet can be moved together with its actuating collar 14 into the position shown in fig. 3. In this case, the one or more stop elements 19 can be passed.

In such an embodiment, the second permanent magnet 18 is arranged directly below the third permanent magnet 13. The second permanent magnet 18, when it comes to its geometry, is generally constructed as explained above for the first permanent magnet 12. Only its outer diameter may be slightly smaller. A second permanent magnet 18 is fixed at the bottle neck 8. The fixing is carried out in such a way that the second permanent magnet cannot rotate relative to the bottle neck 8 but maintains its position.

The basic structure of such an embodiment is thus illustrated.

The manner in which the first embodiment operates can best be understood by comparing figures 2 and 3.

Each of the three

permanent magnets

12, 13, 18 has one pole pair, preferably two or three pole pairs, as seen in the direction along its circumference. Each pole pair consists of a south pole and a north pole, i.e. two poles with opposite attractive forces. The pole pitch of the three permanent magnets is typically the same as seen in the circumferential direction.

Fig. 2 shows the interlocked state, in which the cap 3 is held tightly on the bottle 2.

In this state, the first permanent magnet 12 and the second permanent magnet 18 are oriented such that their poles are flush, respectively. This means that each north pole of the first permanent magnet 12 is located directly or at least substantially above a south pole of the second permanent magnet 18. The same description preferably applies to each south pole of the first permanent magnet 12 and the second permanent magnet 18. The third permanent magnets 13 are arranged in this state with opposite orientations to each other. Each of its north poles is preferably as exactly flush as possible with the south pole of the first permanent magnet 12 and at least substantially flush with the south pole of the second permanent magnet. This means that each north pole of the third permanent magnet is located just or at least substantially above a south pole of the first permanent magnet 12 or the second permanent magnet 18. In this way, the third permanent magnet 13 attracts both the first permanent magnet 12 and the second permanent magnet 18, preferably so that a maximum holding force is achieved.

Fig. 3 shows in a snap shot the unlocked state shortly before the lid pops up in the direction of the longitudinal axis L during opening.

Here, the user rotates the manipulation ring 14 in the circumferential direction. The user moves the third permanent magnet 13 in the circumferential direction with the manipulation ring. The third permanent magnet 13 is thus oriented in the opposite direction to the first permanent magnet 12 and the second permanent magnet 18 in this adjustment. Each of its north poles is now preferably as exactly flush as possible with the north pole of the first permanent magnet 12 and at least substantially flush with the north pole of the second permanent magnet 18. The third permanent magnet 13 thus exerts a strong repulsive force against the first permanent magnet 12. On this basis, the cover 3 is pressed upward in the direction of the longitudinal axis L and then springs up. The rod 4 together with the applicator is then pulled out by the scraper 7 and the cap 3 is preferably completely removed and separated from the bottle 2.

The second permanent magnet 18 has in this embodiment the function of a reset element for the third permanent magnet 13. Because the second permanent magnet 18 repels the pole of the third permanent magnet 13 with its pole-as before-the pole above the second permanent magnet. A torque is generated at the third permanent magnet 13 in this way even when the poles of the two permanent magnets are exactly superposed one above the other. As soon as the user no longer applies a torque in the opposite direction at the actuating ring 14, said torque rotates the third permanent magnet 13 back into its initial position. This restoring moment is even more pronounced from the outset if the poles of the second permanent magnet 18 and of the third permanent magnet 13 are only substantially flush with one another or even have a certain degree of misalignment.

Here, fig. 4 is to be noted. The figure schematically shows the neck of a bottle when the bottle is opened. The bottleneck 8 can be clearly seen. The third permanent magnet 13 and the second permanent magnet 18 can also be seen clearly. These two permanent magnets are best seen since the handling ring 14 is omitted from the illustration of fig. 4.

It can be seen very clearly that the permanent magnet in the preferred embodiment based on fig. 4 has two pole pairs each, i.e. alternately a south pole, a north pole, a south pole and a further north pole each.

It is also clearly visible that the permanent magnet has a slot 23. The permanent magnets are fastened in a rotationally fixed manner by form fit to the lid 3 or to the bottle 2 or to the actuating ring 14 by means of the grooves.

Of particular interest in the illustration of fig. 4 is that the positioning means can be seen here. The positioning means are constituted in this example by a raised, preferably arrow-shaped region 24. These regions each form a funnel-shaped narrowing of the groove 25. This groove 25 extends along a corresponding projection of the cover 3, respectively, when re-latched. This results in that the cap 3, when it is fitted, is always necessarily placed at the bottle neck 8 in such an orientation that the first permanent magnet 12 of the cap is oriented with its poles in such a way with respect to the third permanent magnet 13 in its rest position, thus achieving an attractive force which is sufficient for closing or, ideally, even maximum.

The second embodiment corresponds in function to the first embodiment. The same applies here, if no further consequences result from the differences in the design of the structures described in the following.

This second embodiment is schematically shown just clearly in fig. 5.

The basic structure and the way of operation correspond to what is shown in fig. 1 to 3. The difference here is that in this embodiment, only the first permanent magnet 12 and the third permanent magnet 13 are present.

The second permanent magnet is replaced by a spring element 20, which is designed here in the form of a torsion spring. The torsion spring, as one can clearly see, forms a spring eye (Federauge) which is wound around the neck 8. The spring element 20 forms

free arms

21 and 22 at both ends.

The free arm 21 is bent at the end, for example. The free arm projects into an opening in the bottle neck. The free arms 21 are thus secured against the bottle neck.

The free arm 22 is likewise bent at its end, for example. The free arm projects into an opening in the actuating ring 14. The opening is formed, for example, starting from its inner surface. The arm 22 is thus fastened at the steering ring. The spring element thus becomes a return spring for the operating ring 14.

The user can turn the operating ring 14 and with it the third permanent magnet 13 in the circumferential direction to counter the continuously increasing stress of the spring element 20. This is done until the third permanent magnet 13 repels the first permanent magnet 12 in the manner and method described above and the cover 3 thus pops up.

As soon as the user releases the actuating ring 14 and no corresponding torque is applied any longer, the spring element 20 forces the actuating ring 14 back into its initial position. The third permanent magnet 13 is guided back into its original position with the operating ring. Once the cap 3 is again fitted onto the bottle 2, the third permanent magnet is now ready to attract the cap 3 or the first permanent magnet 12 of the cap again.

When permanent magnets are currently referred to, these are hard magnetic materials such as ferrites or neodymium or the like, which after magnetization substantially retain their magnetic repulsion capability permanently without further energy input. Bare steel with a low remanence that it will permanently retain is not a material in this sense.

The permanent magnet can of course also be formed from a plurality of very small, plastic-bonded magnetic particles. The permanent magnet can be formed in particular from a magnet powder on the lid side and the bottle side, which becomes an integral component of the lid wall or of the bottle wall or of the shoulder of the lid or of the bottle during injection molding.
