Definitions
- the invention relates to a dispensing and dosing device with a housing consisting of a housing body and a housing head and a satellite arranged in the housing body and containing the medium to be dispensed, the satellite having a means for dispensing the medium arranged on the side of the housing head ice.
- a compression spring designed as a spiral is arranged between the housing and the satellite.
- a pressure stamp is arranged in the housing body below the satellite, the satellite being located between the pressure stamp and the housing head and the pressure stamp being in engagement with the pressure spring.
- a rotary receptacle is provided on the end of the container body opposite the container head and serves to receive and rotate the compression spring. The rotation of the compression spring causes the pressure plunger to shift.
- Such a propellant-free spray can is known from DE 38 32 938.
- This has a cylindrical bottle body, in the interior of which a satellite containing the fluid to be sprayed is arranged.
- a spray head connected to the satellite via a valve is arranged above the bottle head of the spray can, while a pressure stamp exerts pressure on the satellite inside the spray can.
- the plunger engages a coil spring which is fixedly connected to a rotary receptacle which forms the end part of the spray can opposite the bottle head.
- the spiral spring is rotated in the bottle body, so that by corresponding receiving grooves of the pressure stamp for receiving at least one spring turn, the pressure stamp can be moved up or down. It is thus possible to build up pressure on the satellite so that when the spray head is actuated, the fluid is sprayed.
- a guide insert is arranged between the coil spring and the satellite and has recesses which extend in the longitudinal direction for guide elements of the pressure plate.
- the force required to turn the rotary holder is relatively high.
- it can come to such a tension of the spring in the spring receiving grooves of the Drehste pels that rotation of the rotary mount is virtually blocked or the rotary mount jams.
- a packaging for paste-like or viscous, generally semi-liquid masses is known from FR-PS 663 516.
- This package comprises a rigid container with a dispensing opening, the contents of which are dispensed by means of a piston plate actuated by a coil spring rotating about its axis.
- the spring extends through the piston plate and is free on the output side of the piston for pressure relief, on the other side compressed between the piston plate and the container bottom.
- a container part connected to the bottom end of the spring is rotated, and the resulting spring rotation pushes the piston plate toward the opening.
- a refill satellite is not planned.
- U.S. Patent 3,838,796 shows a pocket-like fluid and Paste dispenser with a rigid housing, a flexible bag located therein, which contains the fluid or paste to be dispensed.
- An elastic element such as a coil spring extends between the housing and the bag.
- a plate is attached to the lower end of the coil spring and the upper end of the coil spring is connected to an annular flange.
- the bag remains pressure-free after assembly until the plate is released from a latch. The spring can then pressurize the material contained in the bag via the plate.
- the invention has for its object to provide a spraying and dispensing device in which the rotary holder can be actuated easily.
- the dispenser and metering device thus comprises a housing consisting of a housing body and a housing head and a satellite arranged in the housing body and containing the medium to be dispensed, the satellite having a means for dispensing the medium arranged on the side of the housing head.
- a compression spring designed as a spiral is arranged between the housing and the satellite.
- a pressure stamp is arranged in the housing body below the satellite, the satellite being located between the Druckste pel and the housing head and the pressure stamp being in engagement with the pressure spring.
- a rotary mount is provided on the end of the housing body opposite the housing and serves to receive and rotate the compression spring. The rotation of the compression spring causes a displacement of the pressure stamp, the pressure stamp on its radial outer side being configured as a plurality of projections. Deten point supports, so that the compression spring presses against the point supports.
- point supports greatly reduces the frictional forces acting on the compression spring and the risk of the compression spring jamming, thus enabling simple, effective operation of the spraying and dispensing device. These are important acceptance criteria. In addition, damage to the satellite is largely excluded and it can be completely emptied. The use of the refill device according to the invention is particularly economical.
- the plurality of point supports corresponds to one turn of the compression spring, i.e. the point supports are distributed over a full circle of 360 ° and a full turn of the spiral spring lies on the point supports.
- the point supports are evenly distributed over a full turn of the compression spring, i.e. the point pads are evenly spaced from each other.
- the number of point pads is preferably six. It is expedient to provide a support for the compression spring on the pressure stamp with play, thereby preventing the compression spring from jamming. At the same time, a direct pressure transmission from the compression spring to the satellite is possible, since the compression spring is no longer clamped.
- guide grooves are preferably formed in the axial direction in the inner surface of the housing body for receiving a respective point support, the number of guide grooves being less than or equal to the number of point supports.
- the number of guide grooves in the housing body is preferably three.
- a protective jacket is arranged between the compression spring and the satellite, which has longitudinal grooves for reaching through and guiding the point supports. In the case of the six point supports, these are also six longitudinal grooves, the longitudinal grooves being open at the bottom, that is to say for the rotation.
- the protective jacket is preferably attached to the bottle body on the side of the housing head.
- the satellite has a valve with a spray head, the spray head protruding from the bottle head.
- the valve is preferably fastened to the satellite by means of a screw connection. This enables the satellite to be reused, which can be refilled.
- the valve can be made of plastic. This makes the satellite fully recyclable.
- the housing body has a cylindrical shape.
- the pressure stamp is carried out with a 6 x 60 ° point support with play within the spring turn. This prevents the pressure stamp from being squeezed when the pressure is generated within the spring winding, with the result that a friction-minimized pressure and thus a balanced spring pressure come into play. For the operator, this means enormous relief when generating pressure, since the pressure stamp guide is exposed at the upper edge of the spring and does not clamp the spring as in the prior art, which previously led to an interrupted power transmission during pressure generation.
- the protective jacket ensures optimal alignment the elements of the pressure stamp to the compression spring and satellite are achieved, furthermore an optimal standard for the user is achieved in terms of safety, since the mechanical pressure-generating part is completely shut off. Due to the pressure transmission designed as a print run, optimal protective functions against damage to the satellite can be achieved, since the grooves for guiding the satellite can be kept very narrow and the risk of damage to the satellite by the spring is therefore low.
- valve of the satellite by means of a screw connection, reusable use is achieved.
- satellites can be exchanged when used or when changing media.
- each satellite can be refilled, whereby complete waste prevention is achieved. Since the valve can be made of plastic, the satellite is absolutely recyclable.
- the spraying and dispensing device according to the invention can be used for all sprayable substances or fluids such as hairspray, body spray, shoe spray and cosmetic articles without the use of any propellant gas.
- the spray can as a dispenser or dosing device for viscous media, e.g. Use ketchup, mustard, mayonnaise, washing lotion, toothpaste etc. It is then e.g. another spray or dispenser head with different dimensions is required.
- a completely new field of application of the device according to the invention results from the use of two-chamber satellites.
- the two separate chambers for two media to be mixed can be dimensioned in relation to one another in such a way that a mixture of an assigned mixing chamber is dispensed in the desired ratio with a rotary actuation, for example a fluid mixture for hair dryers.
- a further smaller satellite can be arranged in a satellite such that the pressure stamp always pressurizes both satellites simultaneously.
- the diameters of the two nested satellites must be adjusted.
- the inside of the satellite can also have a partition to form two chambers in such a way that the pressure stamp always pressurizes both satellite chambers simultaneously.
- a mixing tube and a mixing chamber from which the medium mixture is discharged are expediently provided.

- the plunger 6 has point supports 12 on its radial circumference, which, as will be explained later, rest on the winding of the spiral spring 7 or are guided by the spiral spring 7.
- the plunger 6 moves up or down on the coil spring due to the point supports 12 (depending on the direction of rotation) in order to achieve this rotary movement, ie thus the plunger 6 is not simply the same Is rotated high, at least some of the point supports 12 are in engagement with corresponding grooves of the bottle body 3, which are arranged on the inside of the bottle body 3 in the axial direction.
- This forced guidance of at least some of the point supports 12 m the grooves 13 an upward or downward movement of the pressure stamp 6 can be achieved.
- the latter dodges sideways and, for example, the compression spring 7 is blocked or itself damaged.
- a protective jacket 5 is arranged between the compression spring 7 and the satellite 8, so that an impairment of the satellite on the part of the spring 7, for example by jamming, can be excluded.

- the cylindrical protective jacket 5 has at its upper end a flange-like widening 30, the lower edge 31 of which serves as a stop and slide bearing for the spiral spring 7. Furthermore, the flange-like widening 30 is used to fasten the protective jacket 5 at the upper end of the bottle body 3.
- the attachment can consist, for example, of a weld.
- the protective jacket 5 points in the axial direction Longitudinal grooves 14, in the preferred embodiment 6 pieces, which are open at the bottom, ie in the direction of the rotary mount 4.
