Description

Cosmetic product dispenser

The invention relates to a cosmetic product dispenser for dispensing liquid to pasty masses, comprising a dispenser housing having a dispensing nozzle in a dispenser head and a reservoir formed in the dispenser housing, wherein the reservoir has a bottom and the mass in the reservoir can be made smaller in volume.

Such cosmetic product dispensers have already become known in various respects. Reference is made, for example, to US Pat. No. 2,477,552. The storage container is under a constant, acting on the ground pressure according to a spring. When the exhaust valve is actuated, mass therefore emerges. Further, reference can be made to US 5772079 B. In this known cosmetic product dispenser, the storage space, while reducing the same, is sucked out by means of a pump.

From DE 202012008396 Ul a cosmetic product dispenser is known with a reducible storage space, for which purpose by means of a piston is acted directly on the mass in the reservoir.

Based on the illustrated prior art, the invention has the task of specifying a cosmetic product dispenser, in which a costly output of the product can be carried out without a complicated valve training or pumping mechanics.

A possible solution of the problem is given according to a first concept of the invention in a cosmetic product dispenser, in which it is geared to that in the storage room a container is added, that in terms of its volume is reducible, wherein the container is a bellows or a bag.

Thus, there is provided a cosmetic product dispenser in which the liquid to pasty mass is received in the reservoir in a bag or bellows, and by manual action, the volume of the mass can be dispensed by displacing the bottom in the dispenser housing. It is a mechanically very simple formable cosmetic product dispenser created.

In principle, the bottom can for example be formed immediately as a piston, so that by the movement of the piston, by pressure from below on the piston, mass can be output. Such pistons which are guided over one or, for example, two mutually arranged circumferential sealing lips in a cylindrical reservoir, which are often also referred to as follower pistons, are known, for example, from DE 202008011825 U1. In contrast, in the context of the present application, the piston is actively movable by a user. The floor can also be designed as desired. It does not have to cooperate sealingly in the sense of a piston with an inner surface of the storage space wall.

Further features of the invention are described below, also in the figure description and the drawing, often in their preferred assignment to the already explained concept or illustrated. However, they can also be of importance in an association with only one or more individual features which are described here or represented graphically, or independently or in a different overall concept.

It is also preferred that the container has a connection opening, with which it leads in the interior of the dispenser housing to a dispensing orifice. connects the line section of the dispenser head. The connection opening can be smaller than the usual diameter of the container, but also larger. It can therefore be provided a taper in the ceiling region of the container, which represents a tapering of the diameter of the container up to an output line cross-section.

The fact that the connection opening is formed directly on the container, possibly in a tube-shaped connection section projecting on the top side, can form a favorable sealing arrangement of the connection opening of the container in the dispensing head. The connection means of the container can also be formed oriented on the diameter of the container. With regard to a bellows formation of the container, for example at the inner or outer fold edge or in between. In any case, this provides manufacturing advantages if, as is preferred, the container itself, in particular in the form of a bellows, is a plastic injection-molded part. It can be demolded so cheap.

The action means is further preferably provided such that it acts on the ground via a spindle means. In this case, in particular, such spindle configurations can be realized, as they are known, for example, in lipstick housings.

The action means may be directly connected to the ground.

Also, a container bottom of the container may be connected to the ground. For example, a bond may be provided, at least when the ground is to be moved without rotational movement relative to the housing. The dispensing mouth can also be closed by a valve which can be opened by overpressure, as far as it can be generated manually in the container by said adjustment. The container may in particular be a bag. More preferably, it is designed as a bellows bag. In contrast to a conventional bellows this container has only one - in the use state upper - opening. The bellows bottom, as well as preferably a container bottom of another embodiment of the container, is closed.

The action means, with which the container, for example, said bellows by means of action on the bellows bottom, or the volume of the storage space as such (when forming the bottom as a piston, for example) to move by hand, may preferably be to move latching, so that a User feels a clear detent position after a certain movement section. Thus, for example, it can be supported that always equal amounts of mass are output.

Alternatively or additionally, provision may also be made for the action means to be moved (only) by way of a reverse rotation lock. This can be ensured that only one application movement can be made, but not a suck back of mass, such as in the pantry by moving in the opposite direction. On the other hand, in particular in the case of a firm connection of the container bottom with the action agent, a back rotation can also be provided, for example in order to achieve a back suction effect of the mass at the dispensing mouth.

The invention will be further explained with reference to the accompanying drawing, which, however, shows only exemplary embodiments. Hereby shows: 1 shows a cross section through a cosmetic product dispenser, in a starting position (without dispenser cap).

FIG. 2 shows a dispenser according to FIG. 1 with a modified connection section; FIG.

FIG. 3 shows a starting muzzle modified compared to the dispenser according to FIG. 1 or FIG. 2 and further modified connecting section;

FIG. 4 is an illustration according to FIG. 2 with the floor partially raised; FIG.

Fig. 5 is a view according to Figure 1, but wherein the mass is not received in a container, but by a piston is volume reducible; 6 shows an illustration according to FIG. 1, with respect to the upper area, in an exploded view, with a further modified connection area; and

Illustrated and described, first with reference to Figures 1 and 2, a cosmetic product dispenser 1, which can serve to dispense liquid to pasty masses, for example, to dispense a cream or an oil.

The cosmetic product dispenser 1 has a dispenser head 2, in which a dispensing mouth 3 is formed. Furthermore, the cosmetic product dispenser 1 has a dispenser housing 4, in which a storage space 5 is formed. In the storage space 5, a container 6 is further added, which is reduced in size with respect to its volume. The embodiment is a designed over a substantial part of its length as a bellows container.

Further, in the dispenser housing 4 as a means of action, a movable bottom 7 is formed, which is in the dispenser housing 4 vertically, that is movable along a longitudinal axis A. The bottom 7 in this case extends substantially perpendicular to the longitudinal axis A.

The bottom 7 is preferably not provided co-rotating in the vertical process. Thus, a firm connection can also be formed between the container bottom 10 and the bottom 7, for example an adhesive connection. This connection can be advantageous in that, when the bottom 7 is returned, but which may also preferably be excluded according to other embodiments, a back suction effect can be achieved, in order to withdraw a certain amount of mass from the dispensing mouth 3. In this respect, the repayability of the bottom 7 can also be limited. The agent is to be moved by hand. For this purpose, in the illustrated embodiment, on the bottom side of the cosmetic product dispenser 1, a rotary part 8 to be twisted by hand is provided. With this rotary member 8 can be acted on, for example, spindle means which are formed here as a telescoping spindle drive 9. Without that the rotary member 8 moves relative to the dispenser housing 4 in the direction of the longitudinal axis A, the action means, so here the bottom 7, can be moved in the manner described.

The volume-reducible container 6, in this case in particular the bellows, has a container bottom 10 and, in the exemplary embodiment of FIG. 1, a container ceiling 11. The container bottom 10 and the container ceiling 11 are provided substantially in superimposition. When projecting in the direction of the longitudinal axis A, the container bottom 10 and the container ceiling 11 overlap.

While the container bottom 10 and the container wall is otherwise closed, the container cover has an opening 12, through which mass can enter into a head-side line section 13 or can flow to the dispensing opening 3.

The opening 12 is formed in the embodiment of Figure 1 and preferably by a extending in the direction of the longitudinal axis A container line section 14. This container line section 14 at the same time provides a desired tight connection to the dispenser head 2. In the exemplary embodiment and preferably, a likewise line-like engagement means 15 is formed on the dispenser head 2, which engages in the container line section 14. Thus, a sealing connection between the inner surface of the container conduit section 14 and the outer surface of the engagement means 15, which in turn has an inner free passage for passage of mass, can be achieved. In particular, at as preferred manufacture of the container 6 made of an elastic plastic material, the dimension be made so that there is a certain expansion and thus elastically effective contact between the container line section 14 and the engagement means 15 in the assembled state.

For favorable implementation of the assembly, an annular support member 20 is further provided. The mounting part 20 has an inner opening 21, through which the container line section is inserted. According to an extension of the container line section 14 upwards towards a Überschnappeffekt can result and thereby the container 6 in total be supported on the support member 20.

Since the support member 20 further radially outward has a support portion 22 with which it rests on an end face of the dispenser housing 4, thereby a favorable mounting option is achieved even before placing the dispenser head 2 on the dispenser housing 4.

In particular, not only limited to this embodiment, it is preferable that the container 6 or the mass as such, see also the following comments on the embodiment of Figure 6 is introduced into the pantry 5, at first not yet placed dispenser head 2, namely with respect to the container 6 in the filled state. Then, the dispenser head 2 is placed or, as usual in this manufacturing area, bounced on.

FIG. 4 shows a partially raised floor 7. Accordingly, the container 6 is reduced in size, here folded over a substantial part of its length. The illustrated bellows is preferably a plastic injection part. In the case of the embodiment of FIG. 1, the region of an upper fold, or else with respect to another separation point, can be fixedly connected to the further, lower part, for example adhesively bonded or welded, in order to achieve favorable manufacturability. On the other hand, a preparation may be provided with an example decaying core.

In the embodiment of FIG. 2 deviating connecting means of the container 6 are formed on the dispensing head 2. In this case, a ceiling section 23 of the container is enlarged radially outward, so that an integrally formed on the container 6, that is, of the same material produced therewith, is produced. ter, support section 22 results. This in turn comes on an upper face of the dispenser housing 4 for support. After placement of the dispenser head 2 on the dispenser housing 4, it is then clamped between a corresponding bottom of the dispenser head 2 (in the radially outer region) and said end face of the dispenser housing 4 in the connection state. Alternatively, the support portion may also be formed by a separate part, which is otherwise glued or welded to the container 6, for example. In the embodiment of Figure 3 connecting means are formed, which in terms of the bellows on a diameter close to the inner

Diameter of a fold are located. Such a container and in particular such a bellows may therefore also be produced advantageously in one piece in the plastic injection molding process.

With regard to the intermeshing of the container conduit section 14 and the engaging means 15, both in the embodiment of Figure 1 and in the embodiment of Figure 3, the conditions may also be reversed. This is such that the container line section 14 engages in the interior of the engagement means 15.

The container mouth 3 can be seen in the embodiment of Figures 1 and 2 as in the direction of the longitudinal axis A and preferably concentric with this coincident bore formed, which opens into an end face 16 of the donor head 2.

In the embodiment of Figure 3, the dispensing mouth 3 is formed laterally facing. In detail, the dispenser head 2 in this case has a first tube or a bore 17, with which mass can be conducted from the container 6 through the dispenser head 2, which tube 17 in one of the donor mouth 3 upstream in the flow direction vestibule 18 opens. The antechamber 18 can be seen with a larger cross-sectional area formed transversely to the flow direction of the mass, as the tube 17. Thus, there is a certain calming and slowing down here at the outlet of the mass until it finally exits at the dispensing opening 3.

In terms of manufacturing, it is preferred, as also shown in FIG. 3, that the dispensing opening 3 is formed with the storage space 18 in a separate part which is plug-connected to a second lower part of the dispensing head 2, in which the tube 17 is formed.

Incidentally, the dispenser head 2, as can be seen, inter alia, from FIG. 3, can be locked with the part of the housing which adjoins the bottom and forms the storage space 5.

In the embodiment of Figure 6 is given a similar configuration as in the embodiment of Figure 1. In contrast to a simple clamping holder, however, a plug-in holder is additionally provided by plug-in jumpers 19, which engage in a corresponding plug-in recess 24 in the end face of the storage container for assembly.

In the embodiment of Figure 7 is also a comparable embodiment as given in the subject of Figure 1. However, the support section 22 rests here on a seal 25, which is additionally arranged on the front side of the dispenser housing 4.

Even with an embodiment according to FIG. 2, the ceiling section 23 may be formed with plug-in projections 19 and / or the support section 22 may rest radially on the outside on a seal 25. All disclosed features are essential to the invention.
