Definitions

• the invention relates to a device for receiving and delivering a spreadable material with a cylindrical receiving element, on the open delivery end of which a closure cap is detachably placed and in which a piston-shaped element is arranged so as to be longitudinally displaceable, which can be operated from the outside and at the other end of the Receiving element provided actuating means for material metering is displaceable.
• Such a device has long been known, for example, as a "Pritt" brand of glue stick.
• a glue stick has a cylindrical sleeve, the open discharge end of which is provided with a releasable closure cap when not in use in order to avoid drying out of the adhesive in the sleeve.
• the adhesive within the sleeve is poured into a piston-shaped element and, together with this, is held in the sleeve so that it cannot rotate, and is arranged to be displaceable in the longitudinal direction of the sleeve, the piston-shaped element being provided with an internally threaded bore in the center, into which a screw spindle engages, which extends almost over the entire length of the sleeve and thus also through the adhesive and at the end integrally merges into a type of knurled nut which is rotatably mounted at the other end of the sleeve and which projects outward from it, that is to say at the foot of the sleeve and a handling of the device is made possible by turning the knurled nut in one direction or the other while the sleeve is held tight, so that the piston-shaped element and thus the adhesive mass associated therewith moves in one direction or the other relative to the sleeve and either an adhesive dispenser or a reinsertion Enables the adhesive
• the object of the invention is therefore to improve a generic device in such a way that it requires less material while maintaining full functionality and at the same time improves handling.
• the actuating means have a first part which is arranged inside the receiving element and is effectively connected to the piston-shaped element and a second part which can be coupled to this and which is integrated in the closure cap and can be coupled to the first part by placing the closure cap on the other end.
• the piston-shaped element is non-rotatably mounted in the receiving element and has an internal screw thread
• the first part of the actuating means has a rotatable screw spindle mounted in the receiving element, which interacts with the internal thread of the piston-shaped element.
• the configuration is such that the first part of the actuating means does not protrude downward from the cylindrical receiving element, in order to avoid incorrect operation without first putting the closure cap on.
• the screw spindle of the first part is designed with a coupling element for the rotationally secure coupling of the second part.
• the coupling element is designed as an internal toothing
• the second part of the actuating means is designed as a pin-shaped web with a corresponding external toothing.
• the receiving element is provided on the outside with at least one profile running in the longitudinal direction, which interacts with a corresponding counter-profile in a sleeve-shaped jacket element, the receiving element being insertable into the jacket element at least in some areas, and that Sheath element has actuating elements at the end opposite the introducer for the receiving element which correspond to the second part of the actuating means.
• the device according to the invention can also be used as a refill cartridge which is placed in a permanent remaining jacket element is used with the user, the product mass then being moved by removing the closure cap by actuating the coupled actuating elements. The cap itself is then not used as an actuator.
• FIG. 1 shows a device according to the invention with an attached closure cap
• FIG. 2 shows the device according to FIG. 1 with the closure cap removed before the same is placed on the other end of the device and
• FIG. 3 shows the device according to FIGS. 1 and 2 with the closure cap placed on the other end of the device and thus serving as an actuating member.
• a device according to the invention for receiving and dispensing a spreadable material is generally designated 1 in the drawing.
• This device can be designed, for example, as an adhesive stick if the spreadable material is an adhesive compound, or else as a lip care stick if a suitable product is selected for the spreadable material. Other applications are of course also possible.
• the device 1 initially has a cylindrical receiving element 2, the upper end of which, in the state of use, is designated 3 and the other rear end is designated 4.
• a circumferential bead 5 is provided on the outside on the cylindrical receiving element 2, which bead serves to receive a sealing cap 6 in a latching and tight manner.
• this closure cap 6 has a circumferential inner locking bead 7.
• the closure cap is provided with a centrally arranged pin-like web 8, which is in the region of its Free end is equipped with an external toothing 9. The function of this web is explained in detail below.
• the cylindrical receiving element 2 has in the region of its end 4 a bottom region 10 which merges towards the inside into an inwardly directed annular region 11 which ends in an annular stop 12. Above the bottom area 10, the receiving element 2 is preferably extended with a slightly tapered diameter into an annular area 13 which is open at the bottom.
• a piston-like or plate-shaped element 14 is inserted into the cylindrical receiving element 2 so that it cannot rotate, but is guided so as to be displaceable in the longitudinal direction with respect to the receiving element 2.
• the piston-shaped element 14 can have longitudinal profiles on its outside, which interact with counter-profiles on the inside of the receiving element 2 and bring about the non-rotating arrangement.
• the piston-shaped element 14 has a base region 15, on the outside of which an annular projection 16 is formed on the underside, which forms a minimum distance from the base region 10 of the receiving element 2.
• the piston-shaped element 14 merges into a sleeve-shaped region 17 which extends approximately to the upper edge of the piston-shaped element 14.
• This sleeve-shaped area 17 has an inner bore with an internal screw thread 18.
• a spreadable material 20 is poured in such a way that this spreadable material protrudes like a pin upwards into the interior of the receiving element 2, namely in its full state up to about the upper edge of the receiving element 2.
• the spreadable material 20 provided with a continuous inner recess or inner bore 21.
• the annular region 11 of the receiving element 2 with an annular stop 12 serves to mount a first part of actuating means for longitudinally displacing the piston-shaped element 14 with respect to the receiving element 2.
• This first part of the actuating means initially has a screw spindle 22 which is connected to the Internal screw thread 18 of the piston-shaped element 14 cooperates and largely over the stretches the entire length of the receiving element 2 to its delivery end 3.
• This screw spindle 18 merges at its other end into a spindle sleeve 23, which widens into a circumferential bead 24, which bears against the annular stop 12 of the annular region 11 of the bottom region 10 of the receiving element 2 and a displacement of the screw spindle 22 from the excludes position shown in the figures in the longitudinal direction downwards.
• the spindle sleeve 23 merges into a cylindrical region 25 with a smaller diameter, in such a way that this region 25 bears in the annular stop 12 of the annular region 11 in a rotatable but supported manner.
• circumferential locking beads 26 are preferably provided on the cylindrical region 25 of the spindle sleeve 23.
• the screw spindle 22 If, during the first assembly, the screw spindle 22 is pushed through from below through the annular area 11 in the base area 10 of the receiving element 2, in which the latching bead 24 then engages behind the annular stop 12, the screw spindle 22 can be rotated, but in the longitudinal direction ⁇ direction due to the locking bead 23 and the locking beads 26 fixed in the receiving element 2.
• the spindle sleeve 23 is extended downward into a tubular region 27, to which a surrounding, cross-sectionally L-shaped region 28 is preferably formed in a circumferential manner, which approximately fills the inner cross section of the annular region 13 of the receiving element 2.
• the tubular area 27 of the spindle sleeve 23 is provided on the inside with an internal toothing 29, which corresponds to the external toothing 9 on the pin-shaped web 8 of the closure cap 6.
• the function of the device 1 is as follows:
• a circumferential locking bead 30 is preferably provided on the outer circumference of the annular region 13, so that the closure cap 6 is rotatably held on the annular region 13.
• the screw spindle 22 is thus rotated, as a result of which the piston-shaped element 14 forcibly moves in the longitudinal direction with respect to the receiving element 2 and, with a corresponding direction of rotation, the product mass 20 to the desired extent from the open end 3 of the Device 1 protrudes and enables application of the product to a surface or the like.
• the closure cap 6 is rotated accordingly in the other direction, so that the piston-shaped element 14 with the product mass moves downward again in the receiving element 2, whereupon the closure cap 6 is again pulled off the other end 4 and onto the open end 3 is placed and is then finally in the closed position shown in Figure 1.
• the device can only be actuated if the closure cap 6 is removed and used as an actuating element, so that incorrect operation with the closure cap 6 still closed is reliably avoided.
• the closure cap 6 thus assumes a double function as a closure element and as an actuating element, so that, unlike in conventional devices of this type, an additional actuating element in the form of an actuating element which constantly protrudes downward from the receiving element is unnecessary.
• the device 1 according to the invention can also be used as a refill cartridge if a sleeve-shaped jacket element remaining with the user is used, which is constructed in principle in such a way as the closure cap 6 or which is constructed such that the receiving element 2 is secured against rotation can be inserted into the casing element and the casing element is then even equipped with an actuating element which can be rotated relative to the casing element and which can cooperate with the actuating means of the screw spindle 22 of the device 1.
