Applicators for dispensing cosmetic products, such as mascara, typically have a container with a threaded neck fitted with a wiper. An applicator having an axial wand is fitted at one end with a threaded cap and at the other end with an application means, typically a brush. The threaded cap engages the neck to seal the tank. The wiper has a diameter selected to allow the wand to pass and to wring the application means, e.g., the brush loaded with product for application when the applicator is removed from the tank.
Typically, the tank is a plastic component generally formed by molding. The wiper typically is a separate component, often made of elastomer, which can be snapped into the neck. The applicator is generally formed by assembling at least three components: a component forming an outer cap, a component cast in a single piece of plastic having a wand fitted at one end with an insert or part that can be snapped into the outer cap, and an application means, e.g., a brush, fitted to the other end of the wand.
The wiper is a component, sometimes an independent component, which is much acted upon in the axial direction when the applicator is removed from the tank for the purpose of applying the product contained in its tank. When the applicator is withdrawn, the application means exerts an axial pressure which tends to separate the wiper from the rest of the tank. This problem can be exasperated when some of the product gets deposited in and possibly dried around the central orifice of the wiper or in this orifice.
Furthermore, over time, the viscosity of the product tends to increase, which increases the frictional drag exerted by the application means on the wiper. As a result, the risk of the wiper being torn out and dragged along by the applicator is increased.
Given the variety of products to be packaged, it may be necessary to have specific application means adapted to particular products, in the same way that it may be necessary to use different application means to obtain certain particular makeup effects. But whatever the reason for modifying the application means, it is generally necessary to give the wiper a geometry adapted to the application means. In many cases, this may make it impossible to mold a wiper when it does not constitute an independent component, particularly relative to the neck.
Furthermore, in many prior art applicator dispensers, the tank and the neck form a molded component cast in a single piece, with the tank having a skirt added to the neck via an inner shoulder in such a way that, particularly for aesthetic reasons, the cap and the tank have one and the same outer cross-section. The product filling operation is long and impractical, particularly with mascara, insofar as a relatively viscous product has to pass through a relatively narrow neck. For commercial reasons, it is important for the product to be regularly renewed.
Examples of applicator dispensers are shown in the following French patents, and more particularly in the figures indicated: FR 2 850 549 (FIG. 1), FR 2 796 532 (FIG. 1), FR 2 796 530 (FIG. 1), FR 2 779 041 (FIG. 1), FR 2 771 907 (FIG. 1B), FR 2 762 494 (FIG. 9), FR 2 745 481 (FIG. 9), FR 2 648 686 (FIGS. 1 and 2) and FR 2 627 068 (FIG. 1).
In one aspect, an applicator dispenser for a cosmetic product, such as mascara, has an axial direction and includes a container. The container has a neck which is typically threaded on the outside. A longitudinal tank is fitted with a lateral wall and forms a cavity for the packaging the cosmetic product. The neck can be integral with a wiper of the application means having a swaged wiping part delimiting a central orifice. An applicator for the cosmetic product includes a cap which can grip the applicator. The cap typically has an outer shell and an insert threaded internally so as to engage with the neck by screwing to provide a sealed closure of the container. An axial wand can be fixedly attached by its upper end to the insert and by its lower end to an application means. The application means can be physically immersed into the product when the head is screwed onto the neck for the purpose of taking out a fraction of the product for use.
The lateral wall of the tank forms or comprises at its upper part a straight, typically annular, skirt, open at its upper end. An upper opening of transverse cross-section SR can range from about 50 mm2 to about 150 mm2. The container has a component for closing the opening integral with the tank. The closure component, which is typically a molded component distinct from the tank, includes a upper part forming the neck, a peripheral part engaging in a sealed way with the straight skirt of the tank via an axial assembly, and a lower part engaging with the wiper forming a forward axial stop for the wiper. The wiper can be formed as a molded component distinct from the closure component. The wiper includes a central part forming the swaged part and a lateral part engaging with the lower part of the closure component by a secondary assembly, so as to form an assembly component.
This applicator dispenser configuration helps to ensure that the wiper is fixedly attached to the closure component by engagement of its central part with the lower part of the closure component. The wiper may have a central part adapted to any type of application means so as to wring the application means. The central part may be adapted to any shape or any type of application means.
The applicator dispenser also has a tank having an opening of relatively high transverse cross section, which facilitates the operation of filling the tank with the cosmetic product. The applicator dispenser makes it possible to obtain, apart from technically advantageous functions, a variety of new shapes.

The applicator dispenser (1) was made in accordance with
The components forming the applicator (6), and the components (5) and (7) forming the assembly component (8), were assembled. Then, two types of unit were formed: a so-called traditional unit comprising the applicator (6) and the container (2) formed by assembling the assembly component (8) with the tank (3). This traditional assembly is adapted for traditional product filling. A second unit included the tank (3) and the closure unit (9) formed by screwing the applicator (6) to the assembly component (8). The second unit allows faster filling of the tank (3).
These alternatives relate in particular to the method of sealed engagement between the tank (3) and the closure component (7) or the assembly component (8), as can be seen in
In addition to resolving problems associated with conventional applicator dispensers such as those relating to the wiper, the applicator dispenser (1) can be constructed in a large number of different embodiments, only some of which have been shown in the Figures. As a result, the applicator dispenser (1) can be customized or adapted to meet the requirements of each customer. Moreover, the applicator dispenser (1) provides several advantageous technical contributions, both as regards the neck seal, and the possibility of faster filling and/or using different types of tanks.
Components of the applicator dispenser (1) can be manufactured by usual means of injection molding and can be assembled by axial snapping. Together this can provide a method of assembly that is relatively easy to automate.
It will be understood that while the invention has been described in conjunction with specific embodiments thereof, the foregoing description and examples are intended to illustrate, but not limit the scope of the invention. Other aspects, advantages and modifications will be apparent to those skilled in the art to which the invention pertains, and these aspects and modifications are within the scope of the invention and described and claimed herein.
