Definitions
- the invention relates to a method for filling a dispenser with a fluid to be dispensed, in particular a pasty mass, the dispenser having a head piece and a fluid container with a filling opening which is closed by the head piece after the fluid has been filled into the fluid container.
- the invention further relates to a fluid dispenser, in particular for pasty material, with a head piece which is placed on a fluid container while closing a filling opening thereof.
- Dispensers of the aforementioned type are suitable for dispensing flowable fluid media, including pastes.
- Filling machines that are used to fill a dispenser have filling tolerances and, in this context, slightly different fill levels in the media storage container of the dispenser.
- air can remain in the storage chamber of the fluid container with a filling volume at the lower limit of the tolerance range (minimum filling quantity) Donation channel reach and can lead to interruptions in the flow of the medium to be donated. This is perceived by the consumer as annoying or can be used in applications where precise dosing behavior is important, e.g. with pharmaceutical products, lead to considerable difficulties.
- a method for filling a dispenser and a dispenser of the type mentioned at the outset are known from EP-A-263 995. There is overfilling of the memory compensated by a deformation of a trailing piston arranged in the storage tank. With a filling volume at the lower scatter limit, however, air can get into a dispensing channel there.
- the invention is therefore based on the object of improving a method and a fluid dispenser of the type mentioned in such a way that a smooth filling of the dispenser which leads to improved functional properties of the dispenser also takes into account the filling tolerances of the filling machine and a dispenser which is improved in use be created.
- This object is achieved according to the invention in a method of the type mentioned at the outset in that when the headpiece is placed on the fluid container, a projecting region of the headpiece first comes into sealing contact with the fluid and, after the headpiece and the like have been made to provide an airtight seal for a storage chamber of the fluid container Sliding the head piece over a predetermined displacement path for moving the head piece in an end position on the fluid container through the head piece fluid is displaced from the fluid container into a discharge channel of the head piece.
- a projecting area of the headpiece When the headpiece is put on, a projecting area of the headpiece first touches and immerses the medium in the fluid container. Until an airtight seal occurs between the head piece and the fluid container, air is displaced from the storage container, which is located above the material to be dispensed.
- the content of the fluid chamber (preferably a pasty mass) is compressed by the further movement of the head piece and the predetermined, fixed displacement path. As a result, fluid can be pressed in a pumping chamber and fluid delivery channel of the head piece, without the fluid, however, reaching a discharge orifice of the fluid delivery channel.
- Pump dispensers can be filled with fluid for the first time by targeted dimensioning of the displacement path and the volume displacement that occurs, possibly also partially filling a discharge channel downstream of the pump chamber, which leads to the discharge opening, so that fluid can be dispensed in a controlled manner with the first or a subsequent dispensing stroke.
- the displacement path is chosen so that a fluid inlet opening of the head piece that can be connected to the dispensing mouth of the head piece always remains immersed in the fluid.
- a filling level in the fluid container is set during filling so that the volume displaced when the headpiece is put on is between a predefinable maximum and minimum volume volume until the first airtight seal. Overfilling is avoided on the one hand and air pockets in the head piece are avoided on the other hand.
- the above-mentioned object with regard to the dispenser is achieved according to the invention in a dispenser of the type mentioned in the introduction in that the head piece has a tubular chimney part projecting into a storage chamber of the fluid container, the fluid displacement volume of which corresponds at least to a volume of a pump chamber of the head piece.
- an annular groove is provided on a bottom side of the head piece for receiving a container wall of the fluid container surrounding the filling opening, the depth of which, based on the position of an upper edge of this container wall, when air is first sealed off and in an end position, which is present when the Dispenser is completely assembled, corresponds at least to the predeterminable displacement path.
- the annular groove and the upper edge simultaneously take on the function of sealing the fluid chamber and enable the headpiece to be displaced relative to the fluid container beyond the first airtight seal of the storage chamber to the locked end position of the headpiece on the fluid container.
- a locking device for fixing the end position is preferably provided between the head piece and the fluid container.
- This can be provided particularly easily in the area of the upper edge on the one hand and the annular groove on the other hand and can be designed, for example, as a snap or snap connection.
- this snap-in or snap-in connection then also fulfills the position fixing of the head piece on the fluid container in the fully assembled state of the dispenser, i.e. in the end position of the fully assembled head piece.
- the fastening device between the head piece and the fluid container can also be designed, for example, as a screw connection, which enables the storage container to be refilled particularly easily after emptying.
- FIG. 2 shows the dispenser in the partially assembled state, the head piece being partially pushed onto the fluid container, at the beginning of an air exclusion of a fluid chamber of the fluid container, and
- FIG 3 shows the dispenser in the fully assembled state, with the head piece on the fluid container in an end position.
- the dispenser 1 consists of a fluid container 10 for receiving a pasty mass to be dispensed and a head piece 20.
- the fluid container 10 forms a hollow cylinder which has a filling opening 11 at the upper end (facing the head piece 20), which allows a storage chamber 12 provided within the fluid container 10 to be filled.
- the fluid container 10 is delimited by a bottom wall 15.
- the cross section of the filling opening 11 corresponds to the cross section of the storage chamber 12, so that a trailing piston 14 can be inserted through the filling opening 11 into the fluid container.
- a fastening section 13 is provided on the outer wall of the fluid container 10 for a snap connection to the head piece 20. This fastening section 13 is designed here as a snap or snap connection, but can also be designed as a thread.
- the head piece 20 has a pump head 20 a, which contains a pump chamber 29 delimited by two check valves.
- the head piece 20 has a bottom wall 22 on a side facing the fluid container 10, from which a tubular chimney part projects as a projection 21.
- the projection 21 ends in the direction of the fluid chamber 10 in an end wall 23 with a fluid inlet opening 24.
- This fluid inlet opening 24 communicates with a downstream pump chamber 29, which in turn is connected to a fluid delivery channel 29 a connecting the pump chamber 29 to an opening 28 of the head piece 20.
- annular groove 25 is formed on the bottom side, which is delimited in the radial direction by a locking contour 27 of the pump head.
- this annular groove 25 engages with an upper edge 13 of an upper wall section of the fluid container 10, which extends around the filling opening 11.
- the fastening section 27 of the head piece 20 also engages with the fastening section 13 of the fluid container .
- the fastening device 15, 27 can also be designed as a screw connection, a groove base 26 of the annular groove 25 then serving as a stop.
- the filling of the dispenser is explained below with reference to FIGS. 1 to 3.
- pasty material to be dispensed is filled into the storage chamber 12 of the fluid container 10 using a filling device.
- the volume to be filled is set on the filling device. This is calculated from the geometric conditions of the fluid container 10 with the trailing piston 14 and a desired fill level in the storage chamber 12. Due to filling tolerances of the filling device, there are fill level fluctuations in the fluid container 10 between a minimum fill level A and a maximum fill level A 2 .
- FIGS. 2 and 3 shows a partially assembled state in which an airtight seal between the head piece 20 and the fluid container 10 is achieved for the first time.
- the sealing effect is ensured by a predetermined engagement position of the fastening section 27 of the head piece 20 with the fastening section 15 of the fluid container 10 with simultaneous internal contact between the upper edge 11 of the fluid container 10 delimiting the filling opening 13 and a cup-shaped inner section 26a of the head piece 20.
- a tubular chimney part (projection 21) or its end face 23 comes into contact with the pasty material in the fluid container 10, so that this is displaced by the head piece 20 from this projection 21 and between the head piece 20 and air located in the fluid container 10 is pressed out via the snap connection 15, 27.
- suitable devices for example grooves, are provided on the fastening device 15, 27. Due to the displacement of fluid caused by the tubular projection when the head piece 20 is placed on it, the fill level rises, as shown in FIG. 2, in order to reach the fill level B shown in FIG. 2, depending on the initial filling, when the airtight seal is closed for the first time.
- the minimum filling level B1 is reached in FIG. 2, the level of the medium being outside, ie radially around the projection 21, higher than the opening 24 provided on the projection 21.
- the distance ⁇ B to the opening edge 13 of the storage container, as shown in the left half of FIG. 2, is maximum.
- the right half of FIG. 2 shows the maximum fill level B2 which is reached when a fill volume has been filled in at the upper scatter limit of the filling device. Then the distance ⁇ B of the level to the opening edge 13 becomes minimal.
- the displacement volume of the projection 21 is dimensioned such that the minimum distance .DELTA.B is very small, ideally zero, that is, when the airtight seal is closed for the first time, all the air is displaced from the storage chamber 12. As long as ⁇ B remains less than or equal to zero, no medium is pressed out of the dispenser.
- the head piece 20 and the fluid container 10 are moved further towards one another in order to reach the end position shown in FIG. 3, ie the fully assembled state of the dispenser. Both are displaced relative to each other by the displacement path X, the opening edge 13 penetrating further into the annular groove 25. The contents of the storage chamber are compressed due to the airtight seal. Due to the pressure increase in the fluid container 10, medium is pressed into the head piece 20. Due to the predetermined displacement by the fixed path X, the head piece 20 is filled with a precisely definable volume of medium.
- this defined volume is chosen so that the displacement by the path X leads to the filling of a pump chamber 29 in the head piece 20, so that a quantity of medium defined by the piston stroke can be dispensed already when the medium is first dispensed.
- the flow resistance for pressing medium through the opening 24 in the direction of the mouth opening of the head piece 20 is chosen so that hardly any medium penetrates into the head piece 20 until the airtight seal is reached, so that an increase in the level of the medium in the fluid container 10 outside the Projection 21 and the associated squeezing out of residual air from the container is made possible.
- the flow resistance is selected so that after reaching the airtight seal when moving by the path X medium can penetrate into the head piece 20 without the trailing piston 14 being moved or being substantially deformed.
- this flow resistance is determined by the elasticity of a valve 30 arranged just above the opening 24, which is designed here as a check valve opening into the pumping chamber 29.
- the check valve 30 is designed point-symmetrical to the axial direction of the dispenser and is arranged concentrically to a central axis of the dispenser running in the axial direction.
- the opening 24 always remains immersed in the medium during a displacement by the path X, so that during the subsequent dispensing no air that may still be in the storage chamber can get into the dispensing channel of the head piece 20. Even when filling with a volume at the lower scatter limit, a minimum fill level C1 is reached in the end position, which allows the opening 24 to be in constant contact with the medium. With a filling volume at the upper spread limit, the maximum filling level C2 is reached.
- the filling volume to be set on the filling device or a desired filling level to be achieved on the fluid container 10 is dependent on the filling quantity scatter of the filling device, the fluid container cross section and the position of the opening 24 is determined.
- the height L of the projection 21 is chosen so that it before first time airtight seal comes into contact with the medium in the storage chamber 12. The height L is limited by the displacement volume of the projection 21 when immersed in the medium, because otherwise medium is pressed out between the fluid container 10 and the head piece 20 before the first airtight seal is reached.
- the filling quantity to be set on the filling device is further determined as a function of the displacement path X and also the viscosity of the medium.
