Abstract

The dispenser has a storage for containing a product (12) in the free-form, and an outlet (18) for discharging the product. A plug (20) completely closes a straight way of the product from the storage to the outlet in one operating condition. The plug includes a wall that traverse to the straight way, and a passage that traverse to the wall. The passage is closed in the condition and is partially opened in another operating condition.

Description

The invention relates to an applicator for a liquid, gel-like, pasty or powdery product, in particular a cosmetic product, with
a memory in which the product is recorded in free form, and
an outlet for the product.

Applicators of the type mentioned are known. Especially if the product is in liquid (low viscosity) form, but also in the case of gelatinous, Pasty and powdered products are common in conventional applicators been observed that vibrations of the applicator, as in particular in the Transport from the manufacturer to the dealer, cause the product of the Memory to the outlet and through the outlet passes. Especially those Quantities of the product passing through the outlet are for later (appropriate) Lost use. In addition, they contaminate the applicator.

A problem can also be shocks when transporting in a handbag or the like, so represent in everyday life. Even such shocks can namely cause the product to exit the outlet.

The invention is therefore based on the object, the applicator of the aforementioned To develop such a way that it better against the adverse effects of shocks is protected.

According to the invention, the object is achieved by a barrier that in at least an operating state, a straight path of the product from the memory to the outlet at least partially blocked.

Since, according to the invention, the rectilinear path from the reservoir to the outlet at least is partially obstructed, the product must make a kind of "detour" to from the Memory to get to the outlet. In case of shocks, the product will however usually only moved in one direction. Shakes can therefore usually not cause the product to take the "detour". Rather, the product is in the If there is a shock, just hit the barrier or push it against the barrier. without it finding the way to the outlet. In other words it gets through the barrier a mass diversion and concomitant inhibition of mass flow in the case from shaking, for example, by falling down.

By the associated with the barrier increase the flow velocity in use, i. when the product takes the "detour" and through the friction In addition to the flow deflecting walls results in an intense Turbulence and thus mixing of the product, by a possibly existing Separation tendency of the product can be counteracted.

According to a preferred embodiment of the invention it is provided that the Barrier can assume at least two operating states, namely a first operating state, in which they provide a path of product from the store to the outlet in locked in a first measure, and a second operating state in which they find their way in locked to a second dimension that is smaller than the first dimension.

Such a configuration opens up the possibility, for example, for transport from manufacturer to dealer by setting the first operating state one particular great security against reaching the product (unintentionally) through the outlet exit. In contrast, the second operating state with a little less security against Leakage of the product from the outlet for everyday use be useful.

It can be provided according to the invention in particular that the barrier in the first operating state completely blocked the way. This gives you absolute security against leakage of the product from the outlet, for example during transport from the manufacturer to the dealer.

The barrier is inventively preferred from the first to the second operating state adjustable, but not vice versa. In other words, the adjustment is irreversible. In particular, when the barrier the path of the product from the store to the outlet in completely blocked in the first operating state, such irreversibility can be useful. It protects against incorrect operation.

The barrier according to the invention preferably has a wall transverse to the rectilinear one Way and a passage across the wall.

This embodiment is particularly easy to implement.

It can be provided that the passage closed in the first operating state and at least partially open in the second operating state. In turn this embodiment is considered to be particularly easy to implement.

According to a particularly preferred embodiment of the invention, the barrier a cup-shaped device. Such devices are particularly easy to manufacture.

A particularly easy to handle preferred embodiment of the invention provides that the barrier with respect to the memory and / or with respect to the outlet is adjustable.

According to a particularly preferred embodiment of the invention is provided that the barrier in the direction of the path of the product from the store to the outlet is displaceable.

In the aforementioned direction of displacement is usually the Longitudinal direction of a pencil-shaped applicator. In such a case, the invention requires Adjustability of the barrier does not increase the dimensions of the pen in the thickness direction.

Finally, the invention preferably provides that the barrier to a Increasing the pressure in the memory in the sense of an adjustment from the first operating state responds to the second operating state.

With this configuration, an automatic is almost realized because usually a Conveying the product from the reservoir to the passageway with an increase in the Pressure in the memory goes along. So it becomes an automatic adjustment of the barrier from the first operating state to the second operating state during the mere intended use Use of the applicator has been achieved.

In the following the invention with reference to a preferred embodiment with reference to the accompanying drawings with further details is explained in more detail. Show

FIG. 1

an enlarged schematic longitudinal sectional view of an applicator for cosmetic products according to a particularly preferred embodiment of the invention in a first operating state and

FIG. 2

the applicator of Figure 1, but in a second operating state.

The applicator shown in the drawing includes a memory 10 in which a liquid cosmetic product such as lip red 12 is incorporated. The memory 10 is connected via a conveyor channel 14 with a working surface 16 of the applicator. In the Working surface 16 are outlets, one of which is exemplified by the reference number 18 is provided.

In the operating state according to FIG. 1 (first operating state), the memory 10 is closed on its working surface 16 side facing by a plug 20, which is in an opening 22. To seal a sealing bead 24, which is in the first Operating state on the inner wall of the opening 22 sealingly. In the first operating state according to Figure 1, the plug 20 closes the memory 10 tightly, so that also in the case of shocks the lip red 12 not to the outlet 18 on the work surface 16 can get.

In the second operating state shown in Figure 2, the plug 20 is opposite the first operating state of Figure 1 in the direction of the work surface 16 towards shifted. The displacement is limited by a circumferential nose 26 at a Paragraph 28 is striking.

In the second operating state (FIG. 2), the plug 20 seals the memory 10 no longer off. Namely, the plug 20 has passages 30, 32 which are in the second operating state a way for the lip red 12 from the reservoir 10 through the delivery channel 14 to open the outlet 18. This is the case because in the second operating state the passages 30, 32 overlap only partially with the opening 22, in contrast but partially protrude beyond the opening 22.

In the second operating state, the lip red 12 makes a "detour" on his Paths from the reservoir 10 to the outlet 18, namely through the passages 30, 32 therethrough. This detour is accompanied by an increase in the flow velocity as well with friction on the walls of the plug 20, resulting in an intense turbulence and thus mixing the otherwise tendency to separation mass (lip red) leads.

The promotion of the Lippenrotes 12 from the memory 10 via the delivery channel 14 to the working surface 16 with the outlets 18 is due to pressure in the memory 10th If the plug 20 is in the first operating state (FIG. 1), such causes Pressure initially no promotion of lip red 12, but rather an adjustment of the Plug 20 from the first operating state of Figure 1 in the second operating state of Figure 2. Such a pressure build-up, for example, by pressing a (not shown) rotary mechanism, and in fact usually during the so-called Andrehens, i.e. while overcoming any dead spaces in the memory 10 that are not with Lip red 12 are filled. Once the plug 20 has the second operating state (FIG 2), leads because of the passages 30, 32 and the generation of a negative pressure in the memory 10 is no longer that the plug 20 in the first operating state (Figure 1) resets. In other words, the adjustment of the plug 20 is from the first Operating state (Figure 1) in the second operating state (Figure 2) irreversible.

Although the passages 30, 32 in the second operating state (Figure 2) a Promote the Lippenrotes 12 from the memory 10 back to the outlets 18 allow offers the bottom 34 of the cup-shaped plug 20 sufficient protection against unintentionally conveying lip red from the reservoir 10 towards the outlets 18 due to from shaking. Vibration can usually only linear movements trigger, but not movements that make a "detour" around the bottom of the pot 34 through the Make passages 30, 32 through. The plug 20 thus provides in both operating states shown an effective protection against vibration-induced leakage.

Those disclosed in the above description, claims and drawings Features of the invention can be used individually or in any combination for the realization of the invention in its various embodiments essential be.
