DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a cosmetic container including a reservoir having a screw cap for nail enamel, mascara or the like, the reservoir consisting of comparatively hard material such as glass, hard plastics or the like, and the screw cap, when closed, being intended to take a precisely defined angular position relative to the reservoir so as to provide for accurate positioning of outer contours, inscriptions or the like, corresponding stops being provided on the screw cap or within the thread portion of the reservoir for such a stop position to be attained.
REVIEW OF RELATED TECHNOLOGY
A typcal reservoir of the type under regard is constituted by a nail enamel bottle of glass having a screw cap of plastics serving to close the bottle. Although the invention is not limited to this kind of application, this is what is dealt with in the following.
Nail enamel bottles of the generic type frequently are of a non-circular cross-section that is continued by the outer contour of the screw cap. This helps in creating attractive designs, and moreover a screw cap of for instance oval cross-section can be handled more easily owing to more favourable leverage. For the entire unit to offer an attractive appearance once it is filled and whenever used, it must be ensured that the contours of the reservoir and closure cap or of the decoration of the reservoir and closure cap, respectively, are in alignment, having an accurate position relative to each other. Frequently, the closure cap of plastics exhibits a point provided by injection-molding which is likewise intended to take a predetermined position. In the case of nail enamel bottles, it is further important that reliable sealing of the closure cap and reservoir is attained so as to prevent any leakage of liquid on the one hand and any escape of volatile gaseous components on the other, such as volatile solvent components. Because of these volatile components and for avoiding any inadvertent toppling over, nail enamal bottles should allow rapid opening and closing, it being desirable to use a thread of a comparatively high pitch. For the tactile and acoustic control of whether the bottle is tightly closed, there is yet another requirement especially for units containing volatile components. During closing, the user is to arrive at a defined final position without having to pay special attention to this, and he is to receive acoustic and tactile acknowledgement of the fact that the closure cap has locked into the closing position.
Solutions that ensure the uniformity of contours when the unit is closed are known for reservoirs of comparatively soft plastics (see DE 39 42 000 A1). However, because of the given resilience of the material used, these prior art solutions cannot be conferred to reservoirs that are for instance made of glass. Producing reservoirs of glass has the additional disadvantage that comparatively high tolerances have to be taken into account because of the specific manufacturing technology.
OBJECTS AND SUMMARY OF THE INVENTION
It is the object of the invention to embody a reservoir that has a closure cap and can be made of comparatively hard material, such as glass, it being possible to compensate for any manufacturing tolerances and nevertheless to use a thread of comparatively coarse pitch permitting rapid opening and closing.
To comply with these per se rival requirements, it is provided according to the invention that at least one projection is disposed on the upper side of an annular collar of the reservoir, extending over a certain angle at circumference of the collar of the reservoir and, in cross-section, having a stop inclination, a rounded region of transition toward a plateau region that runs approximately parallel to the base surface and a stop shoulder that is approximately perpendicular thereto downwards, at least one recess of a contour which approximately corresponds to the projection and which extends over about the same angle at circumference being disposed on the lower edge of the screw cap, the low
