Cosmetic containers, in particular mascara containers

Abstract

A cosmetics container is disclosed, in particular a mascara container (400), whose components are a container part (401), a container cap (402), a wiper (436), which is inserted into a container neck disposed on a container part, and an applicator (403), which is connected to the container cap and passes through the wiper with a brush rod provided with an applicator brush on its free end. Material intersections, which are realised as detachable form-fit, detachable substance-to-substance or detachable force-fit connections, are formed least partially between the different or coinciding materials for separation purposes, a joining end (412) of the brush rod (411) being connected to an applicator holder (414) by way of a bayonet joint (413).

DETAILED DESCRIPTION

(9) FIGS. 1 to 7 show a mascara container 400 as one embodiment of the cosmetics container according to the invention, mascara container 400 comprising a container part 401 and a container cap 402 provided with an applicator 403, as in particular FIGS. 1 and 2 show.

(10) As FIG. 2 shows, container cap 402 comprises a cap inner part 405 provided with a cap thread 404 and a cap outer part 406, both cap inner part 405 and cap outer part 406 being sleeve-shaped and each comprising a cap bottom 407, 408 on one end and each comprising an opening edge 409, 410, which are disposed on opposite ends of cap bottoms 407, 408 and between which a connection is produced, which can be realized as a press-fit connection, an adhesive connection or a welding connection.

(11) As in particular a synopsis of FIGS. 4 to 7 clearly shows, applicator 403 comprises a brush rod 411 whose joining end 412 is connected to an applicator holder 414 by means of a bayonet joint 413, applicator holder 414 being received in a recess 415 formed in cap bottom 407 of cap inner part 405.

(12) Applicator holder 414 comprises a cup-shaped receiving part 416 (FIG. 5) for receiving joining end 412 with a connective protrusion 417 formed on a cup bottom, a projection 420 of connective protrusion 417, which protrudes over an opening edge 418 of a receiving opening 419 formed in cap bottom 407 of cap inner part 405, engaging behind opening edge 418 after a deformation which is not illustrated and preferably takes place by means of an ultrasonic welding tool in order to connect applicator holder 414 to cap inner part 405.

(13) To form bayonet joint 413, joining end 412 of brush rod 411 comprises two radially protruding, diametrically opposite pins 421, which, as in particular FIG. 6 shows, are disposed at a distance a from a stop collar 423 of brush rod 411 and enable an engagement in a locking groove 426 each, which are formed in a cup wall 424 of applicator holder 414 at a distance a from a cup edge 425.

(14) As FIG. 7 shows, an axially oriented insertion groove 427 is provided for each pin 421 for inserting pins 421 into locking grooves 426 in cup wall 424, such that after inserting joining end 412 into applicator holder 414 by means of an axial feed movement via a subsequent rotation of brush rod 411 around its longitudinal axis, pins 421 can be locked in locking grooves 426. For this purpose, a pretension, which secures the joining end 412 of brush rod 411 in applicator holder 414, can be produced via an embodiment of locking grooves 426, which inclines slightly in the rotational direction, with an abutment of stop collar 423 against cup edge 425.

(15) As in particular FIGS. 2 and 3 show, container part 401 comprises a container body 429, which is provided with a bottom 428 and comprises a receiving opening 430 on the end opposite bottom 428 for receiving a container neck 431. A connective end 432 of container neck 431, whose outer diameter corresponds in size to the inner diameter of container body 429, is inserted into receiving opening 430 in such a manner that a shoulder 434 formed in the cross over area to a thread part 433 of container neck 431 is disposed so as to be flush with an opening edge 435 of receiving opening 430.

(16) A wiper 436 made of plastic is inserted into thread part 433. Wiper 436 comprises a stop collar 439 on the upper axial end of a sleeve 438, which is inserted into container neck 431, for the outer abutment against an opening edge 440 of container neck 431. Stop collar 439 limits an opening 445 using an opening edge 444, opening 445 being formed for passing brush rod 411 through wiper 436. Sleeve 438 is provided with a plurality of fastening tabs 443 on its lower axial end, the fastening tabs 443 being dispersed across the circumference of a sleeve edge 442 and which engage behind shoulder 434, which is formed on container neck 431, when deformed radially outward and after wiper 436 has been inserted into container neck 431 for fixating wiper 436 in its position in container neck 431.

(17) The deforming process for deforming fastening tab 443 can take place corresponding to the deforming process of connective protrusion 417 on applicator holder 414 by means of an ultrasonic welding tool. For this purpose, the deforming process (which is comparable to the deforming of connective protrusion 417, which takes place before cap inner part 405 is inserted into cap outer part 406) takes place before container neck 431 is inserted into container body 429.
