Definitions

  • the invention relates to a dispenser for pasty masses, with a dispenser head and a mass storage container operably releasably connectable to the dispenser head by means of a positive lock, wherein a piston which is movable in the dispensing direction is arranged in the storage container and the dispenser head has a passage opening.
  • a donor of this type is known from DE-GM 80 18 892.
  • the bulk storage container is connected upstream of the dispenser head.
  • the piston rod moving it in the dispensing direction requires a length which corresponds to that of the bulk storage container. Overall, this leads to a fairly long configuration with an increased top heaviness.
  • the dispenser which is designed as a slender free-standing device, can easily fall over despite the widened foot and, for example, carry along utensils such as toothed cups etc. with it.
  • the assignment of the detachable bulk storage container is done by means of the screw connection. Before that, the piston rod designed as a toothed rack must be retracted again, which is done via a gear wheel that projects laterally beyond the dispenser head area and is partially exposed for actuation.
  • the object of the invention is to make a generic dispenser for pasty masses such as toothpaste, cosmetics etc. more convenient, in particular with regard to the allocation of the mass storage container to improve.
  • a generic dispenser of increased utility value is achieved:
  • This is essentially due to the simplified assignment of the mass storage container, furthermore to an unmistakable docking and last but not least to the high tightness achieved of the storage container designed as a cartridge with a trailing piston, its further specific design in this way is that it has a sealing collar for sealing connection to the dispenser head in the area of the passage opening, and that the positive locking means of the cartridge are separate, that is to say they are at a spatial distance from the sealing collar.
  • the corresponding difference in location can be brought to optimum effect from two points of view: on the one hand, the most suitable can be used for the sealing effect, in terms of space and material, under the same premise also for the form-fitting means.
  • such a type of individualization also avoids the use of a storage container that does not have the corresponding features.
  • the use of the trailing piston system implies a suction pump, so that the dispenser mechanism is spatially small.
  • the sealing collar is designed to be pulled inwards with respect to the cartridge, in order to cooperate with a connecting piece of the passage opening of the dispenser head which projects into the interior of the cartridge in the composite state.
  • the correspondingly overlapping sealing compound is particularly advantageous for the pump system with regard to the suction of the mass from the cartridge. There is not even a minimal intake of the wrong air and an associated impairment of the function. What the Form-locking means, it also proves advantageous that they are formed on the cylindrical surface of the cartridge.
  • the antidotes are located on the dispenser housing. It is further proposed that the dispenser head forms a housing which essentially accommodates the cartridge, and that the positive locking means of the housing are formed on the lower edge thereof. This leads to an extreme spacing of the form-fit and sealants. All the spatial levels in between can be used for the indicated individualization, so that, for example, filling contents such as toothpaste, mustard, mayonnaise, color paste, sealant, cosmetics of all kinds are under control with regard to a risk of confusion. Another means of exclusion is that the cartridge forms a valve seat surface for a valve mounted in the dispenser head. Here too, the correct valve function can only be achieved if the correct cartridge is assigned. The valve seat surface is advantageously realized on the sealing collar.
  • Such a collar has a high internal stability compared to the thin-walled cartridge cover etc. due to the shape deviating from the flat ceiling wall.
  • the valve could be formed from the material of the dispenser head with a corresponding setting of the spray compound, it is proposed in a favorable further development that the valve has a valve plate designed as a free-cut tab of an anchoring plate.
  • Such a valve can be selected in the best possible material with regard to the sealing requirements, such as the associated factors of softness or flexibility. It is advantageous that the anchoring plate is clip-fastened below the pump chamber bottom of the dispenser housing. This not only brings a simplified assembly due to free access, but also has the advantage of easy interchangeability if you want to switch from one product to the other in a donation-like manner.
  • the cartridge can be detached from the dispenser head due to its superimposed axial and rotational movement. This leads to a drill-related sharpening of the remaining stock in the docking area. It is thus effectively avoided with simple means that paste-like mass is shifted from the passage area to the dispenser head, for example into the area of the wall, in order to thicken there, which would make it difficult to insert the next cartridge precisely.
  • the passage opening of the dispenser head is chambered, that is to say it has a lattice wall-like structure, which leads to a division of the mass residue and overall increases the coefficient of friction.
  • the dispenser head can be used as an opening tool for the cartridges.
  • the construction has proceeded in such a way that a piercing mandrel is formed in the passage opening to open the cartridge mouth. This is closed, for example, by an extremely thin, skin-like wall, which is taken into account when the cartridge is manufactured. It is also advantageous that the piercing mandrel is designed as a cone tip. The latter can be part of the chambering of the passage opening. Alternatively, it is proposed that the piercing mandrel be designed as a toothed ring. Using the axial and rotational movement of the cartridge, this ring gear practically cuts a hole in the sealing wall of the wall.
  • the positive locking means of the cartridge and the dispenser sleeve are designed in the filling state in the area of the wiper lips of the piston.
  • the piston even takes over the function in this area a kind of support core for the thin-walled cartridge.
  • the positive locking zone is stiffened by wall offset.
  • the further measure that the turning handle of the cartridge is formed by the exhibited section of the wall offset and that the front edge of this wall section forms the installation surface of the dispenser is advantageous.
  • the cylinder wall of the cartridge be designed with a wall thickness that is substantially less than that of the casing, while, of course, maintaining the self-supporting stability in the empty state.
  • This aspect is particularly important for saving material, but also has a favorable starting basis in other respects, namely in such a way that latching lugs can be easily formed on the inner wall of the cylinder wall of the cartridge, which only allow the trailing piston to move in the direction of emptying.
  • the thin walls in particular do not cause any problems when demolding. In mechanical terms, such a backstop of the trailing piston can even dispense with an inlet valve.
  • the so-called hydraulic dispenser system in this context, in which the mass in the outlet channel itself forms a type of check valve, the requirements for an extremely inexpensive dispenser version are met.
  • the mouth of which is sealed.
  • the sealing skin can be attached in a plane that is somewhat set back from the mouth of the mouth.
  • a protective cap is also conceivable.
  • the end at the other end is formed by the trailing piston, which acts like a lid.
  • a sealing skin can also be inserted in the zone of the wall offset, which is predestined for this purpose, which must first be perforated in use.
  • a dispenser which is designed in particular according to claim 1, wherein the dispenser head has an automatically closable dispensing tube, is further characterized by a fixed closing part which overlaps the dispensing tube from above and an axial mobility of the dispensing tube downward into the open position. This leads to a simple and extremely effective self-closing of the donor.
  • a dispenser which is designed in particular according to claim 1, with a closure part molded onto the actuating handle, characterized by a dispensing tube which can be moved axially downward into the open position.
  • a particularly advantageous development in particular also with regard to the desired individualization, results from the measure that the cartridge has at its end facing the dispenser head a flexible, axially compressible bellows section protruding in the dispensing direction. It is therefore partially involved in the design of the dispensing device by shaping the pumping space and moreover acts as a return spring. With regard to the latter function, it proves to be advantageous for the bellows section to have folding stages which are concentric with the central opening.
  • the sealing collar continues in the opposite direction into a short tube reaching into the cartridge space, which has openings at a stepped transition point to the sealing collar for applying a mass component to the paste strand.
  • this mass component can be a mouthwash component.
  • An additional function can also be assigned to the dispensing tube if the dispensing tube designed as an extension of the bellows section is used to form a closing element, the counter-closing surface of which is the mouth opening of the dispenser head. Such a configuration also enriches the aforementioned individualization. It is further proposed that between the actuation button and the bellows section of the cartridge there is a pressure ring which, concentrically surrounding the dispensing tube, rests on the top of the basically conical bellows section. With this measure, actuation forces are concentrated and transferred equally to the bellows section.
  • the pressure ring In order to assign the pressure ring to the dispenser mechanism with simple means, it is waxed with the actuation button on a transverse plane intersecting the longitudinal center axis of the rotationally symmetrical cartridge.
  • the rich distinction between the cartridges favors the packaging of a wide variety of media and dispensing in dispenser doses. Since there are also oil-containing products under such media, for example, but oiling on the bottom would limit the acceptance of such a dispenser, the cartridge is provided with a bottom plug that has an air vent at an elevated point. The loss, albeit a small one, is so safely absorbed.
  • An embodiment is particularly advantageous in that the bottom stopper is cup-shaped and clipped into the downwardly open end of the cartridge.
  • the invention further proposes that an extended end region of the dispensing tube be clip-connected is held at the top in the piston cover and that a loosely inserted outlet valve interacts with a valve seat surface formed in the piston cover.
  • the space required for the piston in the axial direction in any case can be optimally used for the valve chamber thus created. It also proves structurally advantageous that on the one hand the piston forms the upper end of the pump chamber and on the other hand the counterclip means for the dispensing tube to be assigned and finally even the valve seat surface for the outlet valve.
  • a favorable embodiment finally results with simple means in that the outlet valve is supported on a circumferential shoulder of the dispensing tube by means of molded-on spring struts.
  • the heel is formed by the cross-sectional jump between the widened, relatively protruding support for the dispensing end area and the reduced cross-sectional area leading to the mouth. If this runs coaxially to the widened area, depending on the valve construction, this narrowed area can also be used to guide the output valve.
  • Another object of the invention relates to a dispenser system with a self-priming pump head and a replaceable cartridge. Even if the pump head is self-priming, it is desirable, in particular if the pump head is formed with a pump chamber with a valve and the second valve is replaced by the inertia of the pasty mass, so that as much pasty mass as possible penetrates into the pump chamber when the cartridge is inserted that self-priming starts easily.
  • the dispenser system provides that the cartridge be used for the first time is designed with such an effective length that self-priming is ensured by filling the pumping chamber during the insertion of the cartridge and that a cartridge is designed for subsequent use with a short effective length that is only sufficient for an operational connection to the pumping chamber.
  • the pump chamber is configured so as to protrude into the cartridge in the operating position, such that a section of a pump chamber wall is in direct contact with the mass located in the cartridge.
  • the pump chamber therefore dips into the filling level of the cartridge, which displaces the filling of the cartridge into the pump chamber.
  • the pump chamber is - partially - filled.
  • the extent of the protrusion of the pump chamber wall can only be designed differently with respect to a first cartridge and a subsequent cartridge. This is preferably done by changing the effective cartridge length. In a specific embodiment, this is achieved differently in the effective cartridge length by extending the cartridge above a level of the trailing piston in the filled state. The length of the first cartridge is above the Piston, in the filled state, i.e. larger than with a subsequent cartridge. Accordingly, the invention also relates to a cartridge system that consists of a first cartridge and subsequent cartridges.
  • the outer dimensions of the first and subsequent cartridges are the same, while the filling space lengths for the first and subsequent cartridges are different. For example, a lower stand edge with different sizes is formed for this purpose. In the case of the cartridge with a smaller casing on the edge of the stand, the filling space can be extended accordingly without the overall dimensions of the first and subsequent cartridges changing (in terms of height).
  • a dispenser in the form of a cartridge K can be assigned to the dispensers 1 shown in the drawings.
  • the latter is in a releasable connection, so it can be replaced at any time or replaced with a fresh cartridge. In this way, the relatively more expensive dispenser is disposable.
  • the dispenser head 2 of the dispenser which is designed as a stand-alone device, contains an output mechanism, consisting of a pump 3, which can be activated via an actuation button 4 for portion-wise dispensing of paste mass 5.
  • the dispensing path passes centrally through the dispenser head 2.
  • the mass 5 passes one after the other a central opening 6 of the cartridge mouth 6 ', a passage opening 7 of the dispenser head 2, the so-called pump chamber 8, a dispensing tube 9 and finally its upward or side-facing mouth opening 10. The latter is in the closed basic position of the dispenser 1 kept locked.
  • the pumps 3 of the individual dispensers 1 can be designed as an inserted part of the dispenser head 2, but alternatively also from a blanket-like material section of the dispenser.
  • the piston of the piston pump bears the reference number 12. It runs in the pumps which are cylindrical in design here chamber 8, defined in both directions. At the top, the tube-like, continuously open shaft 13 of the piston 12 continues into a sleeve-shaped pressure piece 14 to which the dispensing tube 9 is connected. A clearance F is left between the pressure piece 14 and the shaft 13, which neutralizes a section of the vertical movement of the pressure piece and thus of the piston. This route is primarily carried out without piston displacement, so that at the start of the actuation the orifice opening 10 has emerged from the area of the closing part 11; Only then does the displacement process resulting from the reduction in the volume of the pump chamber 8 take place, which brings about the expression of a strand-shaped, metered portion of the pasty mass 5.
  • the downward displacement of the pressure piece 14 via the actuation button 4 takes place against spring loading.
  • the corresponding compression spring incorporated into the dispenser head 2 bears the reference number 15. It is a helical compression spring, the end turn of the cartridge on which is supported on a horizontal ring wall 16 and the end turn of the push-button on the horizontal collar 17 of the pressure piece 14 finds its abutment.
  • the clearance F is limited by the flanks of an annular groove 18 realized in the sleeve-shaped pressure piece 14, into which an annular collar 19 molded onto the shaft 13 engages.
  • the actuation button is realized as a one-armed lever, which is supported on the ceiling 20 of the dispenser 1 on the actuation side and is fixedly mounted in the end area facing away from the actuation surface 4 'about a horizontal transverse axis 22.
  • the latter Around the Mittelbe Rich the practically the entire clear width of the dispenser lengthwise using the actuation button 4, the attack on the pressure piece 14 takes place.
  • the latter has axially stub-like, cantilevered cross pin 23. These are overlapped in the area of a recess 24 by the legs of the U-shaped key body.
  • the dispenser head 2 is clipped into a housing 25 of the dispenser 1 from below and is held by means of an inner bead 26.
  • the upper support is achieved by the wall offset of the housing 25, since an annular shoulder 27 is formed there.
  • the section of the housing 25 which adjoins the inner bead 26 downwards forms a sheath 28, likewise of cylindrical shape, which surrounds the cylindrical cartridge K in a protective manner in a correctly assigned position.
  • the pump 3 designed as a bellows pump uses a dome-like bellows 29. This is held on the dispenser head 2.
  • the actuating handle 4 of this dispensing mechanism likewise uses a long-lever body, which in turn is mounted in a stationary manner on the left side by a horizontal transverse axis 22.

  • the actuation-side end of the actuation button 4 protrudes outwards through a window 30 of the dispenser.
  • the window defines the basic and operative position of the actuation button through the upper or lower edge of the window 30.
  • the dome-shaped dome of the bellows 29 directly forms the dispensing tube 9 in the center.

  • the tube 9 forms a closing member 32 on the upper side. This sits in the basic position in the mouth opening 33 of the ceiling 20.
  • the closing member has a plate shape and merges into the wall of the tube 9 via radial webs.
  • the openings 34 remaining between the radial webs clear the flow path as soon as the actuation button 4 is pressed down (see, for example, FIG. 11).
  • the dome-shaped cover of the bellows 29 deforms while reducing the volume of the pump chamber 8, so that the pasty substance can escape in portions.
  • the action on the crest is relatively uniform, as a result of a central opening 35 in the actuation button 4.
  • the dispensing tube 9, which is directed upward, projects through this opening.
  • the opening takes into account the need for movement due to the tilting position relative to the tube axis.
  • An inlet valve V1 is located upstream of the pump chamber 8 on the cartridge side, and an outlet valve V2 is located downstream of the pump chamber.
  • the former is designed as a folding valve, the latter is designed as a so-called hydraulic valve, in which the tube 9 has such a length and cross section that the pasty mass 5 therein when the volume is increased the pump chamber keeps the tube channel practically blocked, so that the pump chamber is primarily refilled via the inlet valve V1. At most, this results in sucking back any excess of pasty mass that may remain in front of the opening 10.

The relatively low sucking back effect is even beneficial in that any excess from the previous donation phase is sucked back.
