DE1053748B - Powder compact with fully automatic intermediate lid - Google Patents

Description

The invention relates to a powder compact with an intermediate lid, which is invisible when the box is closed Mechanism when opening and closing the main cover is automatic without any special manual operation is moved in the corresponding sense.

In the case of a powder compact, apart from the elegance of taste, beauty and material value, there is one the most important requirements that the mirror is safely protected from dust by powder. This one Protection is provided by an intermediate lid, which is located between the powder in the lower part of the can when the can is closed and the mirror is in the top of the box.

Many of the previously known constructions have the disadvantage that their intermediate cover with a special Closure must be provided in order to be able to fulfill their actual sealing task. Due to the narrowness within the powder compact, this closure must be so small that it is no longer with the fingertip, but only with the fingernail and therefore often closed Damage to the fingernails. After opening, the intermediate cover, which is under spring pressure, jumps and releases the powder compartment. After use, the intermediate cover must · - · before closing of the main lid - ■ to be closed separately for itself, it necessarily having a jerky Movement over the latching of the lock jumps. With the relatively large area of the intermediate cover This short jerk is enough to puff out so much powder and the mirror at the last moment to gather dust with it.

There are already various powder compacts in which this disadvantage is avoided and in which A special lock is missing for the intermediate cover. The intermediate cover is already moving automatically with the main lid.

In one of these versions, the ceiling! A roller blind is used that covers the powder compartment when the powder jar is closed and rolls up when the jar is opened and unrolls when it is closed. However, this construction has the disadvantage that the powder can be transferred from the underside of the roller blind when it is being rolled up onto the upper side, which in turn causes the mirror to become dirty again. A protection against powder dusting of the mirror by this device is not given. In addition, when the powder compact is open, the mechanism guiding the roller blind is visible and is very annoying with such an article.

Furthermore, a powder compact with an intermediate lid is known in which a leaf spring is attached to the intermediate lid and slides in a guide on the main lid. In this version, however, the intermediate cover itself must be the mirror, as the inner powder compact with a fully automatic

side of the main cover is not available for mirror training. So on the one hand it is a Special use of the mirror is given, and on the other hand there is the mechanism that transmits the movement can be seen when the can is open. However, this box has a separate intermediate lid compared to the cans already has the advantage that the powder box is gently and firmly through one of the main lid is closed from spring pressure acting on it.

It is now also known to separate the intermediate cover, which is hinged offset relative to the main cover to put itself under spring action so that it opens immediately when the main cover is lifted. When the main cover is closed, it is closed again without any special manual operation. These Execution has the disadvantage that when opening and closing a scraping contact of these two covers takes place against each other, so that a mirror attached to the main cover would soon be destroyed.

So as far as powder compacts with an automatic intermediate lid are known, this intermediate lid is either itself mirror - due to the construction - and thus fails its purpose as The mirror, or the movement mechanism, can be fully seen when the can is open, which is tastier Aspect is undesirable.

All these disadvantages mentioned are eliminated by the fact that the transmission of motion from the mirror-bearing Main cover on the intermediate cover, which is hinged offset with respect to the main cover, by means of a The flexible shaft is housed in the powder compact and is invisible even when the can is open. Included the flexible shaft can be given a preload when the powder box is closed, which when the box is closed a firm pressing of the intermediate cover on the powder box ensures and easy sprinkling

effects of the main lid by about 20 ° when opening the can closure. The completely invisible movement mechanism actuates the intermediate cover in a manner that amazes the user when the main cover is opened and closed. Due to the tightly and gently closing intermediate cover, it is hardly possible for the mirror in the main cover to get dirty. As with the known design, the preload ensures that the intermediate cover is pressed firmly against it. However, this pretensioning, which was not yet clearly recognized in the known embodiment, also causes the main lid to spring open after the can closure has been opened and thus a further convenience when using the can. In the drawing, an embodiment according to the invention is explained in more detail in the figures, namely FIG. 1 shows a perspective view of a powder compact according to the invention in approximately 3 / -i open state, the outer shape of which is slightly in unimportant details for reasons of drawing simplicity differs from the shape shown in FIGS. 2 and 3, FIG. 2 shows a sectional drawing through the lower part and the powder box insert ring, FIG. 3 shows a vertical section through the main hinge. This powder compact, shown as a possible embodiment, accommodates all other parts in the two shells, namely the lower part 1 and the mirror-bearing main cover 4. The hinge sleeve 2 is connected to the lower part 1 and the U-shaped tang 3 is rigidly connected to the mirror-bearing main cover 4 by soldering or the like. After the four-edged driver part 5 has been introduced into the U-shaped tang 3 and the hinge sleeve 2, the connection of the two main shells 1 and 4 is established. Since there are now 3 square holes in the U-shaped tang that fit the square driver part 5, and the inner bore of the hinge sleeve 2 is round, the driver part 5 must take part in every movement of the mirror-bearing main cover 4 that rotates in the main hinge (see in particular Fig. 3). This driving part 5, which serves as the hinge axis, has at one end a thickening 11 with a blind hole into which a flexible shaft 6 is soldered in the usual sense. The intermediate lid hinge between the lower part 1 and the intermediate lid 9 is designed in the same way as was described here for the main hinge between the lower part 1 and the main cover 4. Here the powder box insert ring 7 is rigidly connected to a hinge sleeve 8, which is suitably adapted to the shape of the powder box insert ring for better soldering (see FIG. 2). As with the main hinge above, the U-shaped tang 12 of the intermediate cover 9 slipped over the hinge sleeve 8 are also connected to one another by the square part of the driver 10, which in turn is seated in the square holes of the intermediate cover tang 12 can move freely rotating in the cylindrical bore of the hinge sleeve 8. Like the driver 5, this driver 10 is provided with a thickening 13 into which a blind hole for receiving and soldering the second end of the flexible shaft 6 is drilled. The flexible shaft 6 is now soldered in such a way that the intermediate cover 9 just closes fully when the mirror-bearing main cover 4 is still open at an angle of about 20 °. If the main lid 4 of the fully assembled powder compact in this sense is now closed from the fully open state, it rotates with the square holes of its U-shaped tang 3 the driver 5 mounted in the hinge sleeve 2. This driver 5 in turn transmits this rotating movement via the Flexible shaft 6 attached to the other end, with its square part in the square holes of the intermediate lid hinge 12 stuck and guided in the hinge sleeve 8, second driver 10 and thus automatically closes the intermediate lid 9 rigidly attached to the intermediate lid hinge 12 with. The intermediate cover 9 is already fully closed when the mirror-bearing main cover 4 is still open by about 20 °. By continuing to close the main cover 4 fully, a bias is forced in the flexible shaft 6, which on the one hand presses the intermediate cover 9 firmly onto the powder box and thus reliably prevents the mirror from being soiled by powder dust, and on the other hand on the main cover 4 when the powder box is opened again Bias transmits and the main cover 4 automatically opens again by this 20 °. Patent application: 1. Powder compact with intermediate lid operated by a mechanism that is invisible when the tin is closed when opening and closing the main cover automatically without any special manual operation in the corresponding Sense is also moved, characterized in that the transmission of movement from the mirror-bearing main cover to the opposite ⁴ S the intermediate lid, which is hinged offset to the main lid, is made by a flexible shaft that is housed in the powder compact lower part and is invisible even when the tin is open. 2. powder compact with intermediate lid according to claim 1, characterized in that the flexible When the powder box is closed, the shaft receives a pretension that it does when the box is closed A firm pressing of the intermediate cover on the powder box ensures that it pops open easily of the main lid by about 20 ° when opening the can closure.
