Definitions

• the invention relates to a cosmetic dispenser in pen form.
• a cosmetic dispenser has a housing extending in a main extension direction and a discharge opening at a front end of the housing.
• a generic dispenser has a disposed within the housing liquid reservoir and a pumping device which can be actuated via an arranged on a lateral surface of the housing actuating handle and having a pumping chamber, which at an input side with the liquid storage and at an output side with the discharge connected is.
• a generic cosmetic dispenser has a salient feature a special outer shape.
• This outer shape has the shape of a pin, ie corresponds in length and diameter about the dimensions of a conventional fountain pen or the like.
• This genus of cosmetic dispensers which are adapted to a stylus with respect to their external shape, plays a special role among the cosmetic dispensers, since donors of this genus are particularly are transportable and can be stored in particular, where usually pens are kept. More significant, however, is that when they are manually guided in a manner similar to a pen, it allows a particularly high degree of accuracy in applying the cosmetic medium.
• Such media discharged by means of a generic dispenser may include, for example, cover media, lip gloss or eye shadow liquid. They can also be used as eyeliners.
• the object of the invention is to further develop a generic cosmetic dispenser pen shape to the effect that this combines the requirements of small external dimensions, high dosing accuracy and low production costs. According to the invention this is achieved by a generic cosmetic dispenser in the form of a pen, the pump chamber is at least partially limited by a formflexible wall, the outside of which forms the actuating handle.
• the pumping chamber which is preferably bounded on both sides by valves relative to the liquid reservoir and the discharge opening, is variable in terms of its internal volume in that it is limited at least in sections by a flexible wall which is flexible and elastically deformable in order to reduce the pumping chamber volume is.
• a flexible wall is understood to be a wall whose modulus of elasticity is less than 0.5 kN / mm 2 , preferably less than 0.25 kN / mm 2 .
• the features describing the dispenser according to the invention are to be understood as follows.
• the cosmetic dispenser according to the invention has a stick shape. This means that it has a length of at least 90mm in the direction of its main extension direction. Preferably, this length is even greater and is at least 100mm, more preferably preferably at least 120mm.
• the maximum diameter of the cosmetic dispenser is 18mm, but preferably below, especially below 14mm.
• the ratio of length to maximum diameter is preferably between 14: 1 and 8: 1.
• the cosmetic dispenser can be guided with thumb and forefinger, while at the same time it lies in the crook between thumb and forefinger. This is it It is possible to guide the discharge opening of the dispenser very precisely, which is of great importance depending on the cosmetic medium.
• the actuating handle is provided, which is formed by the outside of the inside of the pump chamber limiting form flexible wall.
• the pumping chamber as the main component of the pumping device is provided separately from a liquid reservoir for receiving the cosmetic medium and connected thereto via a channel, which preferably has an inlet valve.
• the reduction of the volume of the pumping chamber for the purpose of discharging the medium takes place via the deformation of the actuating handle, ie via the impressions of the actuating handle in the direction of a central axis of the cosmetic dispenser.
• provision is made in particular for the actuating handle to be actuated with the index finger. It is therefore at least partially preferably between 20mm and 40mm away from the discharge opening. This corresponds to the usual position of the index finger when guiding a pen.
• the cosmetic dispenser according to the invention is particularly inexpensive to produce due to its very simple design.
• the pumping device with a volumetrically variable by means of the actuating handle pumping chamber is particularly suitable to allow a small construction of the cosmetic dispenser, especially with regard to a particularly slim shape of the dispenser.
• Valves in particular overpressure valves, are preferably provided on the inlet side and the outlet side, wherein a valve opening at positive pressure in the pumping chamber can be arranged on the outlet side and wherein a valve opening at negative pressure in the pumping chamber can be arranged on the inlet side.
• the housing section comprising the discharge opening is movable due to the flexibility of the pumping chamber wall with respect to that housing section surrounding the liquid reservoir.
• these housing portions of the housing which are provided on both sides of the actuating handle relative to the main extension direction and thus on the one hand define the discharge and on the other hand limit the liquid storage, designed as a rigid housing sections and connected to each other by a likewise rigid connecting portion.
• a housing section is considered to be rigid if its modulus of elasticity is greater than 0.5 kN / mm 2 , in particular greater than 1, 0 kN / mm 2 .
• the connecting portion preferably forms a counter-force surface, which is arranged in the circumferential direction on the side opposite the actuating handle side of the housing.
• This counter-force surface facilitates the metered application of force to the actuating handle, since the cosmetic dispenser can be supported by means of a finger, in particular by means of the thumb, directly opposite the actuating handle provided on the lateral surface.
• the user's thumb preferably rests against the opposing force surface, while the actuating handle is pressed in by means of the user's forefinger.
• the connecting section can be arranged as a simple web against which the pumping chamber surrounded by the form-flexible wall is pressed in a hose-like manner.
• a more stable and therefore advantageous design provides, however, that the rigid connecting portion circumferentially surrounding the preferably tubular shape-flexible wall and having a recess through which the actuating handle can be actuated.
• the shape-flexible wall as a tubular wall, this is arranged within a sleeve formed by the rigid connecting portion, which preferably occupies a larger part of the lateral surface of the dispenser than the actuating handle itself.
• the connecting portion in particular also in its shape as the formflexiblen wall surrounding sleeve may be formed as a separate component, in which the formflexible wall is inserted in the course of assembly.
• the formflexible wall and the connecting portion are formed as one-piece two-component injection molded part made of different materials. As a result, the assembly is facilitated and reduces the risk of malfunction of the donor.
• valves which separate the liquid storage and the pumping chamber or the pumping chamber and the discharge opening from each other, can be designed as valves with at least one separate component, in particular a valve body.
• a particularly advantageous embodiment provides, however, that at least one of the valves is formed by integrally formed with the flexible wall valve surfaces.
• the flexible wall which also forms the actuating handle, takes on a further function by forming the outlet or inlet valve of the pumping chamber. On separate components can thus be partially omitted.
• Particularly advantageous is a design in which the flexible wall has two adjacent pressure equality on both sides of the valve abutting lips that dissolve at overpressure or negative pressure in the pumping chamber from each other and thus allow outflow or inflow of medium.

• this pumping and discharging unit 30 has a main body 40, an inlet valve unit 50 and a by means of a securing member 62 on the main body 40 fixed application tip 60 with discharge opening 64.
• the main body 40 consists of two sub-components, which are integrally connected as a two-component injection molded part.
• the outer of these subcomponents is a housing sleeve 42 made of a rigid plastic.
• This roughly sleeve-shaped subcomponent has at its end facing the application tip 60 a latching thickening 42a for fixing the securing component 62.
• On its opposite end facing the liquid reservoir 26 it has on the one hand a latching device 42b for coupling the hollow tubular component 22 of the liquid reservoir 26.
• it has an inwardly facing latching groove 42c which serves to receive the inlet valve unit 50.
• This inlet valve unit 50 consists of an insert 52, not shown, which is designed to produce the latching connection with a circumferential latching ring 52a.
• an elastically deformable umbrella-shaped valve body 54 can be latched, which closes the through-channels, not shown, until a deformation of the valve body 54 and thereby opening of the through-channels is effected by a negative pressure within the main component 40.
• a hose-like component 44 is used, which consists of an elastically deformable plastic and which is formed in one piece with the housing sleeve 42 in the above-mentioned manner.
• This component 44 is open only at its front ends 44a, 44b, wherein the front end 44a points in the direction of the inlet valve 50 and wherein the front end 44b points in the direction of the application tip 60.
• This tubular body 44 surrounds a pumping chamber 46. For the purpose of pumping liquid by means of this pumping chamber 46, the internal volume of Pumping chamber 46 can be reduced.
• a recess 42d is provided in the sleeve body 42, through which the elastically deformable tubular body 44 can be deformed in the manner indicated by dashed lines in FIG.

• an outlet valve 48 is provided, which is formed by two valve lips 48a formed as an integral part of the hose body 44, these valve lips 48a abutting one another until the pumping chamber 46 closes, until due to an overpressure in the Pumping chamber 46 are separated from each other and thereby release access from the pumping chamber 46 in the application tip 60 and thus to the discharge opening 64.
• Figure 3 shows the handling of the dispenser 10 according to the invention. This is held in the same way as a pen, being guided by index finger 3, thumb 2 and middle finger 4. He lies at the same time in the crook 5 between the thumb 2 and index finger 3 at. This type of holding ensures that the discharge opening 64 can be guided safely, so that a precise discharge of the cosmetic medium is possible. As can be clearly seen from Fig. 3, in the position of the actuating handle 44c chosen so that it can be easily operated with the index finger, while the pin is supported by the thumb 2 and middle finger 4.
• Fig. 4a shows a delivery state of the dispenser, in which the pumping chamber 46 is still empty. To use the dispenser, this is grasped in the manner described above, so that the index finger 3 rests on the actuating handle 44c. To start up the dispenser 10, liquid must first be conveyed into the pumping chamber 46. For this purpose, in the manner illustrated in FIG. 4b, the actuating handle 44c is pressed through the opening 42d, so that the volume of the pumping chamber 46 is reduced. This results in an opening of the outlet valve 48, so that the air flows in part from the pumping chamber 46.
• Fig. 4d shows a state of the dispenser 10, in which this already has a completely filled with fluid pumping chamber 46. If, starting from this state, the operating handle 44c is pressed with the index finger, with the inlet valve 50 closed, the respective amount of liquid is discharged through the discharge opening 64.
• the immediacy between the volume reduction of the pumping chamber 46 and the liquid discharge leads to an easy way to dispense the liquid through the discharge port 64 in a very metered manner, whereby it is quite easy not only to carry out the desired amount due to the pen-like handling of the dispenser 10 these also at the desired location, in particular the desired area of the skin to discharge.
