Definitions

  • the invention relates to a dispenser for pasty products with a cylindrical container containing the product in a container interior, the bottom of which has a follower piston which is slidable under the pressure of the outside atmosphere on a container inner wall and carries at its upper end a head piece which has a manually operated conveyor with a pumping chamber and a delivery piston and an outlet channel for the product.
  • Such donors are known as outpatient care units in a variety of application areas, e.g. for the distribution of creams for health and personal care, in the area of household chemicals and shoe care products, but also for the provision of pasty foods, luxury foods and spices.
  • the invention is therefore based on the object of providing a dispenser of the type mentioned at the outset, which has a dispensing mechanism of simple and reliable construction, enables dispensing-resistant dispensing of the product and supports a variable design of the external shape of the dispenser.
  • the dispenser should be suitable for the combined dispensing of a two-substance product strand.
  • the side-by-side arrangement of the conveying device and the dispensing unit which is separated from it in terms of movement can, for example, the dispenser advantageously, for example, be elongated in the shape of a cylinder oval cross-section, elliptical cross-section or the like can be carried out without this causing arrangement problems in the area of the headpiece of the dispenser.
  • This advantageously enables ergonomic and stylistic aspects to be taken into account.
  • the strip chamber cylinder and the pump chamber cylinder are designed radially one behind the other so that they have a common wall area. This advantageously supports an integral design of the container, strip chamber cylinder and pump cylinder as an integral, preferably injection-molded plastic component.
  • the dispensing unit which essentially consists of the strip chamber cylinder and at least one mouthpiece body connected to it, which forms the dispensing channel between the upper region of the container and the dispensing opening is defined, determined, has a visor with which the opening and the closure of the dispensing opening that blends the end of the dispensing channel is realized and thus enables a clean working with the dispenser.
  • the dispenser enables pasty products to be dispensed, which are provided, for example, with colored strips distributed on their peripheral surface, for example when dispensing toothpaste.
  • a tubular, first mouthpiece body in the manner of a mandrel is inserted into the strip chamber cylinder and in the upper region of the annular chamber forming the strip chamber is provided with paint dispensing openings, slots or the like which are distributed around the circumference.
  • the length of the first mouthpiece body within the stripe chamber essentially corresponds to the height thereof, ie its extent in the axial direction of the dispenser.
  • the discharge channel in continuation of the first nozzle body, is preferably formed by a second nozzle body provided with the discharge opening, which is partially received in a latching connection on the outer peripheral surfaces of the strip chamber cylinder and the pump cylinder.
  • the second mouthpiece body preferably has a pocket which forms the holder and the abutment for the visor cooperating with the dispensing opening. Furthermore, the second mouthpiece body can advantageously serve as a guide for an actuating sleeve of the dispenser.
  • a particularly simple design of the dispenser is achieved in that a delivery piston, which is slidably guided within the pump chamber which is open downwards to the interior of the container, is accommodated in a snap connection seat on an elongated actuating tube body, which in turn has the actuating sleeve at its other end to actuate the piston.
  • a guide tube section formed on the upper side of the pump cylinder firstly provides external guidance of the actuating tube body and at the same time contributes to the radial fixing of a return helical spring extending between the upper side of the pump cylinder and the actuating sleeve.
  • the dispenser opening can be closed by a visor, which is opened when the dispenser is actuated.
  • the visor is preferably designed in the form of an angled plastic band body with an upper closure section and a lower foot section, the latter being inserted into the pocket of the second mouthpiece body.
  • a simple opening actuation of the visor can be achieved in that two actuating fingers are angled from it in one piece on both sides of the foot section, to which elements of the actuating sleeve each mature in the region of their angling.
  • FIG. 1 shows a dispenser 1 for pasty products according to the present invention in longitudinal section.
  • a product to be dispensed is located within a container 2, the container interior 3 of which merges freely into a pump chamber 5 and a strip chamber 6 on its upper side.
  • the pump chamber 5 and the strip chamber 6 are each delimited by a pump cylinder 7 and a strip chamber cylinder 8, respectively, which are arranged radially next to one another and have a common wall area 9.
  • Pump cylinder 7 and strip comb cylinder 8 form with the container 2 an integral plastic part, which is preferably made as an injection molded part.
  • the other parts of the dispenser 1 which will be explained in more detail below, also consist of injection-molded plastic, preferably of polyethylene or polypropylene, so that the dispenser 1 is very light on the one hand and on the other hand the pasty mass to be dispensed is impaired by the material of the dispenser Donors and vice versa no impairment of the parts of the dispenser 1 which come into contact with the mass to be dispensed due to this mass.
  • a spreading spring follower piston 4 for continuous upward Promotion of the pasty mass inside the container 2 upwards into the pumping chamber 5 is provided along the inner container wall under the influence of the atmospheric pressure slidably and against the pump pressure by a spreading spring follower piston 4, through which the pasty mass in the container 2 constantly under the pressure the ambient atmosphere is kept.
  • a very simple tracking of the pasty product inside the container 2 is ensured upward into the area of a delivery piston 10 and a negative pressure within the container 2 is avoided when the pasty product is dispensed from the dispenser 1.
  • a first, tubular mouthpiece body 17 is inserted from above into a mounting neck portion of the same, which extends essentially into the region of the transition from the strip chamber 6 to the container interior 3 and that of the strip chamber 6 has an annular structure gives.
  • an opening 17 ' is provided, which also forms the beginning of an output channel 29.
  • a pasty dye (not shown here) is accommodated, which extends within the strip chamber, filling the annular space, downwards to shortly before the lower end of the first mouthpiece body 17 and there on the rest of the container interior 3 and the pump chamber 5 filling, dispensing pasty product mass, for. B. toothpaste.
  • the pump cylinder 7 and the strip chamber cylinder 8 have opposite on their outer peripheral surfaces 7 'and 8' locking lugs 27a and 27b, which serve the captive reception of a second, the discharge channel 29 continuing second mouthpiece body 15.
  • this is also a plastic injection-molded part, which is latched onto the pump cylinder 7 and the strip chamber cylinder 8 in the region of a shoulder 26, which is formed toward the container 2.
  • the second mouthpiece body 15 thus forms the end of the dispensing channel 29 with the dispensing opening 16. Its release or closure is effected by a visor 20, which will be explained in detail below and is held with a foot section 22 in a pocket 19 of the second mouthpiece body 15 .
  • a piston delivery device is provided in the remaining area of the headpiece of the dispenser 1, which from the pump chamber 5 delimited by the pump cylinder 7 with the delivery piston 10 slidably displaceable therein, an upper actuation sleeve 13, an actuation tube body 12 connecting the actuation sleeve 13 to the delivery piston a return coil spring 14 biased between an outer top of the pump cylinder 7 and an inner bottom surface of the actuating sleeve 13.
  • a region of the second mouthpiece designed according to the external shape of the actuating sleeve 13 body 15 also serves as a guide for the actuating sleeve 13 (see also Fig. 2).
  • the visor bringing about the closure or the release of the dispensing opening 16, with which the actuating sleeve 13 engages via nose-like projections 25 as shown in FIG. 1, is also explained in more detail below with reference to FIG. 3.
  • the visor 20 made of a plastic band piece has the shape of an angled band body with an upper, essentially circular closure section 21 covering the dispensing opening 16 in the closed position and a middle foot section 22 extending in the extension of an intermediate section of the visor 20, which is in the pocket 19 of the second mouthpiece body 15 is received in a stationary manner.
  • strip-shaped actuating fingers 23 are angled at an angle, the arrangement in relation to the adjacent actuating sleeve 13 being such that the actuating fingers 23 engage under the actuating sleeve 13.
  • the visor 20 By accommodating the foot section 22 of the visor 20 in the pocket 19 of the second mouthpiece 15, the visor 20 is clamped on one side and can be pivotally actuated with respect to its area above the angled portion of the actuating fingers 23 by pressing it.
  • the actuating sleeve 13 is provided with nose-shaped projections 25 (see FIG. 2) with which the actuating sleeve 13 engages the actuating fingers 23 in the region of their angling from the remaining part of the visor 20.
  • the dispenser 1 can be in the area of its head piece be closed off to the outside by a closure cap 28, which can be locked via locking lugs 27b on the second actuating sleeve 13 in such a way that the closure cap 28 forms a smooth, flush closure to the container 2 in the region of the shoulder 26, so that the entire dispenser has a completely smooth outer contour when closed.
  • the dispenser 1 is provided with a container of oval or elliptical cross-section, so that the dispenser 1 can be designed ergonomically and easy to handle.
  • a design is supported by the design of the dispensing unit A, in particular the strip chamber cylinder 8 and the pump cylinder 7, which are arranged one behind the other in the radial direction. Handling is further facilitated in that the actuating sleeve 13 is arranged at a lower level than the dispensing opening 16.
  • this shows schematically the dispenser 1 with the closure cap 28 removed from above, and in addition to the elliptical basic shape of the dispenser 1 it can be seen that the second mouthpiece 15 also has an oval shape in the region of the dispensing channel 29 or the outlet opening 16 and this also applies to the strip chamber cylinder 8.
  • the strip chamber cylinder and the second mouthpiece body 15 can also have a circular cross section in the region of the discharge channel 29. This also applies equally to the container 2 itself, which, if desired, also has the shape of a straight one Circular cylinder with corresponding consequences for the cross-sectional design of the closure cap 28 and the second mouthpiece body 15 can have.
  • Fig. 2 also illustrates the projections 25 of the actuating sleeve 13 for engaging the actuating fingers 23 of the visor 20, whereby of course other shapes can be selected or a non-protruding design of the actuating sleeve 13 securing the attack on the actuating fingers 23 can be selected.
  • the delivery piston 10 has a hat section 10 'for receiving it on the actuating tube body 12 in a snap connection seat and is designed as a stepped piston with an end face leading in relation to the pair of annular sealing lips. This leads to pressure relief and improved sealing in the sealing area of the delivery piston 10.
  • dispenser 1 which is designed as a piston dispenser and in particular as a strip dispenser, by means of which a product strand, for example provided with ornamental colored strips, can be provided in a two-component form, is particularly due to the elimination of all valve devices and the serial arrangement of the conveying device and output unit A des Dispenser 1 is particularly simple and straightforward.
  • the delivery piston 10 is the only part to be assembled from the inside and is received in the pump chamber 5 and then, after the return spring 14 has been put on, by pressing the actuating sleeve 13 with the actuating tube body 12 in a snap fit with the latter.
  • the dispenser 1 already assembled in this manner in its head piece is now filled into a head support, with a dye having a pasty or viscous consistency being filled, for example, into the annular strip chamber 6, to a fill level that is just before the end of the first Mouthpiece body 17, or, until just before the opening 17 'extends.
  • the dispenser 1 is filled with the main product to be dispensed, for example with toothpaste, starting with the filling of the pump chamber 5.
  • the main product mass lies on the dye mass within the strip chamber 6 during the filling process and is at least also in the area the opening 17 'of the first Munsdorf stresses 17.
  • the trailing piston 4 is inserted and the dispenser 1 is ready for operation.
  • the closure cap 28 has already been put on beforehand or is finally received on the second mouthpiece body 15.
  • the operation of the dispenser 1 is explained below. Starting from a state according to FIG. 1 and the container 2 filled with toothpaste, for example, as well as pump chamber 3 filled with toothpaste and the strip chamber 4 filled, for example, with color paste, the color paste resting above the opening 17 'on the toothpaste, is removed after removing the cap 28 the actuating sleeve 13 is pressed downward by finger pressure against the force of the return spring 14.
  • the dispenser 1 when the dispenser 1 is actuated for the first time, it may be necessary first to guide the product mass to be dispensed into the region of the dispensing opening 16 in an idle stroke, so that product mass is stable from the start of the second dispensing stroke the dispensing opening 16 is available.
  • an extremely reliable and clean-working strip dispenser is realized, which is suitable for dispensing a wide variety of pasty products and permits the dispensing of a product in different color patterns.
  • the dispenser 1 as a strip dispenser to dispense pasty food within the strip chamber to provide a spice paste in order to provide the main food product to be dispensed, which is located within the container 2 and the pump chamber 5, with a certain spice admixture distributed over the circumference of the dispensed product strand.
  • the dispenser 1 thus opens up an area of application in the cosmetic / medical field, the area of cleaning and care products, e.g. Shoe creams up to the portioned provision of pasty foods.
  • the cross-sectional shape of the container 2 can be varied widely according to the wishes of the users and e.g. about circular cylindrical shapes, in particular also include elliptical and other bilaterally symmetrical cross-sectional shapes.
