The present invention refers to a packaging providing for the use of a refill applicable for cosmetics having as its main characteristic the de- tachment of the refill by double torsional moment. The invention also provides for the moment applicable on the cap having a different strength than the moment applicable on the base.

Additionally, the present invention refers to a flask refill that is also detachable by torsional moment. Description of the State of the Art

The growing demand for reusable products and the concern with the final destination of polymer-based objects, due to their long degradation time, has led industries in general to modify their product strategies. The culture of reusing materials has been widely disseminated in society, and with this consumers are more aware and give preference to products with an ecological and/or social appeal.

The state of the art for make up product refills is limited, because there are still not many cosmetic packagings that allow content substitution. Most current make up packagings are disposable in the name of practicality. In general terms, the current products that allow the exchange of refill are not portable or are unattractive. The solutions found still provided for substitutions using tabs or other devices to assist the exchange, or complex procedures.

One of the prior arts is described in document US 6.945.419, which reveals a container for cosmetic products in general constituted by an extractable hollow cartridge, by an outer body, and by a cap. Removable locking means are provided between the cartridge and the outer body. The cartridge is threaded to the outer body of the product by the bottom, and the outer body and the cartridge are joined by pressure fixing means exercised by the cartridge protrusions and recesses of the hollow outer body.

Another prior art described in document US 4.705.053 is a make up unit that comprises a container for mascara, an adjuster ring controls the compression and a reservoir of mascara, said refill, is accommodated in a barrel. Thus the degree of compression of the wiper element can be adjusted and, as a result, the force of the wiping action will be adjusted.

The documents described herein provide for the use of refills making the use of the packaging entirely original in aesthetic terms without exposing that there is a refill product inside. However, these products fail to meet the demand of upmarket users, associated to practicality of use and reuse.

The present invention has the advantage of not requiring the use of tools to substitute the refill, the substitution being provided by a single kind of movement. Brief Description of the Invention

Detailed Description of the Drawings As can be seen in figure 1 , a make up packaging 1 , according to the teachings of the present invention, comprises a cap 2, a flask 3 and a refill 4. A view of the flask 3 can be seen in figure 2.

The cap 2, as revealed in figure 3, comprises a cap refill 7 con- nectable to an outer cap container 5. An applicator 10, composed of a wand 14 and a brush 13, can be provided, according to a preferred embodiment of the invention.

The flask 3 comprises a flask refill 8 connectable to an outer flask container 6 and to a base 9. Said flask refill 8 can be seen in figures 4, 6 and 7. Said outer flask container 6 is constituted of materials present in the state of the art.

In terms of packaging use according to the present invention, there are provided three different torsional moments, a first being to connect the flask 3 to the cap 2, the second torsional moment for detaching the flask refill 8, and the third torsional moment to detach the cap refill 7. To ensure the feasibility of this use, the flask refill 8 presents in at least one of the ends at least a lock 15, as illustrated in figures 4 and 5, on which force is applied to carry out the torsional moments. The lock 15 is triangular in shape and when the second torsional moment is applied, it allows the displacement of the flask refill, detaching the accommodation ridges 20 arranged radially to the axis of the flask refill 8. Preferably, the refill is connected through locks commonly used in the state of the art, for example, of the hook kind, in which case it is important to note whether the connection should be less accentuated, so that the combination can be subsequently disassembled by the user.

Besides at least one lock 15, there is at least one anti-rotation device on the refill mounting of the flask 8 and refill of the cap 7 (not illus- trated) and also on the combination of the base 9 and outer flask container 6 of the refill 4. This allows opening without any false turns of any of the parts. The base 9, illustrated in figures 7, 8 and 9, presents axial projections 40 to accommodate the flask refill 8. The base 9 also presents radial ridges 35 that assist the connection of the base to the outer flask container 6. in a preferred embodiment of the invention, when transmitting the first torsional moment, the cap 2 is connected to the flask 3 avoiding spillage of the content of the packaging 1.

When transmitting the second torsional moment, substantially greater than the first torsional moment, the outer flask container 6 becomes released from the flask refill 8 and stays connected to the rest of the packaging 1. When transmitting the third torsional moment, which requires more strength, or a greater torsional moment than the second torsional moment, the cap refill 7 is detached from the outer cap container 5 and thus is detached from the cap 2, thus allowing the withdrawal of the cap refill 7. In the teachings of the present invention, the sequence of operations should be thus so that the user has greater contact area to apply the second force to the combination because if the outer cap container 5 is released first, it would be harder to withdraw the remainder of the refill 4, because the contact area would be smaller. In the preferred embodiment of the invention, to ensure the feasibility of this concept of the invention, the locks 15 and the accommodation ridges 20 should be designed such that the second torsional moment is at least 2.5 to 10 times greater than the first torsional moment, the third torsional moment is about 5 to 25 times greater than the first torsional moment. Further, according to this preferred embodiment, the third moment should be about 2 to 2.5 times greater than the second torsional moment. The connection of the parts with each other occurs within the same range of values. Exemplifying this preferred embodiment, the first torsional moment falls within the range of about 0.1 to 1.0 kgf, the second torsional moment in the range of 1.0 to 2.5 kgf, and the third torsional moment in the range of 2.5 to 5.0 kgf. As can be seen in the example of the embodiment above, the graduation of strengths of the torsional moments is defined without intervals between the ranges, that is, the withdrawal range of a part starts at exactly the same value as the following range begins, forming an uninterrupted sequence of ranges of torsional moments. It is important to point out that substituting the cap refill 7 is applicable preferably in mascaras, however the cap refill 7 can be used for other purposes comprising or not an applicator 10.

The procedure of mounting a new flask refill 8 is carried out by inserting a new refill 4 in the outer cap container 5, forming the combination of the outer cap container 5 and refill 4; next, the combination of the outer flask container 6 and base 9 should be inserted into the outer cap container 5 and refill 4 combination, and transmit the first torsional moment, the connection of the new refill 4 occurs by the same first torsional moment in which the flask refill 8 is encased when the accommodation ridges 20 arranged radially to the axis of the flask refill 8 connect to the outer flask container 6. The process of connecting the cap refill 7 is similar to the process of connecting the flask refill 8, by torsional moment.

It is important to note that the present invention provides an advantage over the solutions of the state of the art whereby it permits the ex- change of the refill from the make up packaging, without compromising the aesthetics of the product and its functional characteristics.

Moreover, the make up packaging now described will not be discarded with said refill is changed, thus avoiding wastage of nonbiodegradable material. It is worthy of note that the structure of the make up packaging and refill, as revealed in the present invention, has a simplified configuration compared to prior arts. Said configuration also provides a reduction in manufacturing costs, which can be passed on to the end consumer.

Additionally, the process of substituting the refill 4, in accordance with the teachings of the present invention, requires no additional procedures besides the torsional moment similar to the opening and closing process of the proposed packaging.

Lastly, the present make up packaging is applicable preferably in mascaras, however said packaging can be used for other purposes.

Having described examples of preferred embodiments, it must be understood that the scope of the present invention encompasses other potential variations, and is only limited by the content of the claims appended hereto, including possible equivalents therein.
