Definitions

  • the invention relates to a cartridge system according to the preamble of claim 1.
  • Such a cartridge is for example in the DE 198 18 455 A1 described.
  • the cartridge filled with a filling substance for example with grease or with silicone, can be emptied in a hand lever press.
  • the cover is removed from the first end of the cartridge and the cartridge is inserted with this end first into an open hand-lever press.
  • the base at the second end of the cartridge is opened by removing the separable base area and closing the hand-lever press.
  • a piston of the hand lever press is inserted through the first end into the cartridge and the filling substance is pressed out through the open base at the second end of the cartridge.
  • the protruding wall area at the second end of the cartridge presses against an annular seal of the hand lever press.
  • the filling substance is emptied by means of an (over) pressure applied by the piston to the filling substance is exercised.
  • cartridges in which the filling substance is emptied via a vacuum by sucking the filling substance at the second end of the cartridge.
  • the cartridge is closed at the first end with a piston which is drawn into the cylindrical base body of the cartridge during vacuum evacuation.
  • a connector in particular a threaded connector, is generally formed at the second end at which the filling substance is sucked in.
  • Cartridges or emptying systems with pressurized emptying of filling substances, in particular of fats are more common than cartridges and corresponding emptying systems with vacuum emptying, but many filling companies also use cartridges for vacuum emptying. These filling companies must therefore decide before or during the filling process into which type of cartridge the fats are to be filled in order to serve a respective sales market or customer with the appropriate cartridges. This means that the filling companies have to keep both types of cartridges in stock in empty packaging, which requires a corresponding storage capacity. In the filling process, the filling machines also have to be adjusted to the cartridge system intended for filling, which causes set-up times.
  • a cartridge system is offered on the website of GR Ferner AB, Sweden (http://hugocartridge.com/en/home), which can optionally be adapted to both emptying systems.
  • the cartridge system has a so-called universal one Lid which has a tear-off collar and a piston area which remains in the cartridge after the collar has been torn off.
  • the object of the invention is to provide a cartridge system which can optionally be used for emptying the filling substances by (over) pressure or by vacuum suction and at the same time has the advantages of previous cartridge systems.
  • this object is achieved by a cartridge system according to claim 1, in particular in that the protruding wall area of the cartridge is set back at least partially in the radial direction relative to the cylindrical base body in order to fasten an adapter that can be placed on the second end of the cylindrical base body, in particular bounced on is.
  • the protruding wall area of the conventional cartridge described above is changed in such a way that it can interact with the adapter without increasing the diameter of the cartridge.
  • the adapter has a geometry which is adapted to a respective emptying system provided for vacuum emptying of the cartridge.
  • the wall thickness of the recessed Projecting wall area typically corresponds to the wall thickness of the cylindrical base body. In this way, the weight advantages that a conventional cartridge for pressure emptying has compared to cartridges for vacuum emptying are retained.
  • the protruding wall area is set back as a whole, ie over its entire height, with respect to the cylindrical base body. It is also possible, however, for the protruding wall area to be set back only partially, specifically at its free end, with respect to the cylindrical base body in order to interact with the adapter in order to fasten it.
  • the protruding wall area is set back by no more than 2 mm compared to the cylindrical base body.
  • the protruding wall area In order to ensure that the protruding wall area at the second end of the cartridge seals off with the sealing ring of a conventional hand lever grease gun, e.g. in accordance with DIN 1283, the protruding wall area must not be offset too far radially inward relative to the cylindrical base body.
  • the offset value described above should typically be observed in order to ensure the sealing effect.
  • the protruding wall area has at least one latching element or a latching edge for interacting with at least one latching element or a latching edge on the adapter in order to secure the adapter to the cartridge, preferably irreversibly, ie not in a non-destructive manner or releasably with considerable effort.
  • Locking elements or a (essentially) completely encircling locking edge are typically used for fastening formed on the protruding wall area, which usually interacts with complementary shaped locking elements or a complementary shaped locking edge on the adapter.
  • the adapter can, for example, have latching elements projecting radially inward on its outer edge.
  • the protruding wall area of the cartridge can accordingly have a circumferential, radially inwardly recessed locking edge and / or radially outwardly and / or inwardly protruding locking elements.
  • the latching system is preferably formed at the end of the protruding wall area that faces the floor.
  • the separable floor area has an inner floor area and preferably a (ring-shaped) circumferential floor area which connects to an outer, non-separable floor area.
  • the inner floor area can be connected directly to the outer, non-separable floor area by a radial section with reduced resistance, for example by a V-shaped groove.
  • an in particular ring-shaped circumferential base area can be provided which forms an intermediate area.
  • the annularly encircling floor area can be connected to the inner floor area and to the outer floor area by a respective section with reduced resistance, for example by a V-shaped groove.
  • the inner base area can be detached in that the ring-shaped circumferential base area is separated from the outer base area and, if necessary, also from the inner base area.
  • the outer base area After separating the inner base area - possibly by releasing the ring-shaped circumferential base area - the outer base area remains, which forms a circumferential collar on the inside of the cylindrical base body.
  • the outer bottom area can prevent the filling substance from splashing out when the cartridge is opened, as cited in the introduction DE 198 18 455 A1 is described.
  • the outer floor area can be used to support the adapter and, if necessary, for an additional locking connection to the adapter, as will be described in more detail below.
  • a smooth passage is formed when the bottom is separated from the cartridge, as shown in FIG FR 2 709 732 B1 is described, that is, no outer bottom area remains on the cylindrical base body.
  • At least one stop projecting above the floor is formed on the outer floor area as a rotation lock for the adapter, the stop preferably being spaced apart from the projecting wall area.
  • a threaded connector is often formed at the second, closed end of the cartridge, which is screwed to a corresponding thread of the evacuation system.
  • the stop can also be used to align the cartridge in a labeling system or during printing in a predetermined manner with respect to the longitudinal axis of the cartridge.
  • a circumferential sealing edge or a cup seal is typically formed on the adapter, which is used for (sealing) contact preferably on the inside of the protruding wall area.
  • the stop is separated from the protruding wall area, i.e. at a distance from it in the radial direction. Since the circumferential sealing edge does not necessarily extend over the entire height of the protruding wall area, the stop can, if necessary, nevertheless be connected to the protruding wall area along a section adjacent to the floor.
  • a pull-off device for separating from the outer base area is formed on the inner base area and / or on the (ring-shaped) circumferential base area.
  • the pull-off device can be, for example, a pull-off ring which is formed on the inner bottom area, as shown in FIG DE 198 18 455 A1 is described.
  • the pulling device can also be formed on the annularly encircling floor area, which extends, for example, between two V-shaped grooves in the floor, as shown in FIG FR 2 709 732 B1 is described.
  • the inner base area can alternatively only be connected to the outer, non-separable base area via a section with reduced resistance, for example by a single groove or by a recess in the base.
  • the cartridge described in DIN 1284 can have a smooth geometry, ie the protruding wall area has a constant wall thickness without a thickening protruding outward in the radial direction.
  • Such a cartridge can usually be used directly in an emptying system for vacuum emptying.
  • the cartridge has a geometry, also described in DIN 1284, with a circumferential bead, its use in a vacuum emptying system may, however, not be possible without further ado.
  • the protruding wall area has a circumferential bead protruding in the radial direction, which is detachably fastened to the wall area.
  • a circumferential bead as described in DIN 1284, can be useful so that the cartridge can be used in certain emptying systems for emptying by means of excess pressure. Due to the bead, however, the cartridge has too large a diameter to be used in some vacuum evacuation systems. For this reason, it is favorable to fasten the bead detachably to the wall area.
  • the bead can be designed, for example, as a separate component which can be bounced or flanged onto the cartridge or onto the protruding edge area.
  • the bead can be molded onto the protruding wall area via an area with low resistance or via a circumferential thin point.
  • the bead can be separated from the protruding wall area, e.g. by means of a pull-off device, before the adapter is attached to the protruding wall area.
  • the problem here may be that the outside of the wall area does not run completely smooth after the bead has been pulled off.
  • An embodiment has therefore proven to be particularly advantageous in which the bead with a small number of point-like connections (for example in the form of thin webs) to the projecting wall area and the bead is otherwise completely spaced from the projecting wall area.
  • the areas between the point-like connections of the bead for separating it from the cartridge can be grasped without any problems and a sufficiently large pull-off force can be exerted.
  • the point-like connections can be provided geometrically in such a way that they tear off almost without leaving any residue and the sealing effect on the protruding wall area is not impaired.
  • the punctual connection can be realized, for example, by webs tapering towards the cartridge or in some other way.
  • the base has a preferably dome-like projection in the separable base area, the end face of which preferably ends flush with an end face of the protruding circumferential wall area.
  • the invention also includes an adapter for placing, in particular for bouncing, on a protruding, circumferential wall area of a second end of a cylindrical base body of a cartridge, which is designed as described above, comprising: an outer wall area for preferably irreversible attachment of the adapter to the protruding Wall area of the cartridge, as well as a preferably circumferential support section for supporting the adapter on the outer bottom section of the bottom of the cartridge.

  • the adapter is attached with the outer wall area to the protruding wall area of the cartridge.
  • the support section which can for example be in the form of an axially extending rib or the like, extends from the flat base body in the same direction as the outer wall area, i.e. in the direction of the bottom of the cylindrical base body of the cartridge.
  • the support section is set back radially with respect to the outer wall area of the adapter.
  • the adapter has a circumferential sealing edge for sealingly closing the second end of the base body, which is preferably designed to rest on an inside of the protruding wall area.
  • the sealing edge is offset radially inward relative to the outer wall area of the adapter and is typically designed in the manner of a sealing lip.
  • the protruding wall area of the cartridge is typically at least partially received between the radially inner sealing edge and the radially outer outer wall area of the adapter.
  • Of the Support section is typically offset radially inward relative to the sealing edge.
  • the adapter comprises a connecting piece, in particular a threaded connecting piece, in which an opening for emptying filling substances is formed.
  • the threaded connector typically protrudes beyond the flat base body on the front of the adapter.
  • the threaded connector can be connected to a thread of an emptying system, which is used for (vacuum) emptying the contents of the cartridge.
  • the thread or its geometry can, for example, be designed to be suitable for a grease gun system from Mato (see "http://mato.de/de/schmiertechnik/fettpressen-standard-lubeshuttle.html"), which enables vacuum emptying.
  • the threaded connector can be designed in the geometry of a silicone cartridge, as it is, for example, in FIG DE 10 2006 055 236 A1 is described. It goes without saying that the adapter can also be used in other emptying systems than those described here.
  • the opening is closed by a closure, in particular by a rotary closure, or by a cover area that is preferably releasably fastened to the socket.
  • the closure (lid) can be, for example, a closure that is injection-molded onto the adapter, can be torn off and, if necessary, reclosed.
  • the closure (cover) can also be designed as a separate component that is screwed onto the threaded connector, for example.

  • the connecting piece can, for example, be injected closed on its upper side.
  • the cover area can be releasably attached to the connector, for example by connecting it to the inside of the connector with thin webs so that the cover area can be broken out. Covering the opening of the adapter by means of the cover area offers the advantage that an area is available on the top of the adapter for operating instructions, ... that may be attached.
  • At least one, in particular rib-shaped, projection extending outward in the radial direction is formed on the support section and serves to rest against the stop serving as a rotation lock for the adapter.
  • the or one of the rib-shaped projections is pressed against the stop when the threaded connector is turned and in this way blocks further rotational movement between the adapter and the cartridge.
  • the threaded connector can be screwed into a receiving thread of a (vacuum) grease gun by rotating the cartridge around its longitudinal axis.
  • At least one, preferably rib-shaped, projection extending inward in the radial direction is formed on the support section, which when the adapter is placed against a pull-off device of the cartridge for pulling off the detachable The bottom area presses in order to prevent the adapter from being attached to the protruding wall area of the cartridge as long as the second end of the cartridge is not open.
  • the pull-off device can be a pull-off ring, for example. If necessary, the projection extending inward in the radial direction can press against the dome-like projection when the adapter is placed in order to prevent the adapter from being attached until the second end of the cartridge has been opened.
  • the rib-shaped projection (s) are designed in such a way, in particular arranged at such a distance from the underside of the adapter or from the bottom of the cartridge, that they, together with the height of the pull-off device, prevent the adapter from bouncing against the protruding wall area, provided that the inner bottom area has not yet been removed.
  • this common height can be selected so that the adapter cannot be pushed or bounced so far onto the cartridge that the locking element (s) on the outer wall area of the adapter lock onto the protruding wall area of the cartridge.
  • the inwardly extending protrusion or protrusions are also designed or arranged so far away from the bottom of the cartridge that a piston can be pulled completely from the first end to the second end of the cartridge during vacuum emptying without doing too much Residual mass of the filling substances remains in the cartridge.

  • the projections can in particular be arranged uniformly distributed in the circumferential direction.
  • a number of approx. 5-10 projections have proven to be advantageous, but more or fewer projections can also be provided on the adapter. In principle, a single protrusion extending outwards or inwards is sufficient to ensure the function.

  • a latching in the opposite direction to the latching on the outer wall area of the adapter can be produced on the outer bottom section of the cartridge.
  • the locking element or locking edge formed on the support section typically protrudes with the free end downwards over the bottom, which may be unfavorable for the stability of the cartridge if the adapter is attached to a cover at the first end of the cartridge, as further is described in more detail below.

  • the cartridge 2 with the attached adapter 4 has a constant outer diameter which corresponds to the standardized diameter of a grease cartridge according to DIN 1284.
  • the protruding wall area 10 of the cartridge 2 has on its outside a locking edge 19 in the form of a circumferential groove into which a radially inward protruding locking edge 20 engages, which is formed on the inside of the outer wall area 18 of the adapter 4 is.
  • the latching of the adapter 4 on the cartridge 2 is ideally irreversible, ie the adapter 4 can cannot be detached from the cartridge 2 without a considerable expenditure of force or not in a non-destructive manner.
  • the adapter 4 has a circumferential support section 21 in the example shown in order to support the adapter 4 on the upper side of the base 7 of the base body 5 of the cartridge 2.
  • the support section 21 is in the in Fig. 5
  • the example shown is designed as an axially circumferential rib which extends from an annular circumferential planar section on the upper side of the adapter 4, which surrounds the threaded connector 16, to the lower side of the adapter 4.
  • a circumferential sealing edge 22 is formed which rests against the inside of the outer wall area 18 of the adapter 4.
  • the protruding wall area 10 of the cartridge 2 is encompassed by the radially inner sealing edge 22 and the radially outer outer wall area 18 of the adapter 4 and overlapped by the adapter 4, so that the second end 6b of the base body 5 is sealed by the adapter 4 and the filling substance can only exit through the opening 17 of the threaded connector 16.
  • the adapter 4 To attach the adapter 4 to an emptying system for vacuum emptying, it is screwed to a corresponding thread of the emptying system by rotating the cartridge 2 connected to the adapter 4 about its longitudinal axis.
  • the outer base area 7c of the base body 5 has a stop 23 protruding beyond the base 7 (cf. Fig. 1a ) on.
  • the stop 23 is radially spaced from the protruding wall area 10 of the cartridge 23 or designed in such a way that it does not collide with the circumferential sealing edge 22 of the adapter 4.
  • rib-shaped projections 24 extending outward in the radial direction are formed on the support section 21 (cf. Fig. 3 ), one of which comes into contact with the stop 23 serving as a rotation lock during the rotary movement of the cartridge 2. It goes without saying that the adapter 4 can also be protected against rotation relative to the base body 5 of the cartridge 2 in a way other than the use of rib-shaped projections 24.
  • rib-shaped projections 25 projecting radially inward are formed on the support section 21. These rib-shaped projections 25 press against the top of the pull-off ring 8 shown in FIGS. Latching of the support section 21 with the in Fig. 5 The illustrated inner edge 26 of the outer bottom region 7c is prevented in this way.
  • the support section 21 can have one or more latching elements or a latching edge at its end facing the base 7.
  • the opening is formed above the latching element 20 and extends partially into a radially inwardly extending wall section 27 on the upper side of the adapter 4, which adjoins the outer wall area 10 of the adapter 4.
  • the radial extension of the locking element 20 corresponds at most to the radial extension of the opening in the radially inwardly extending wall section 27. In this way, there is no undercut in the radial direction of the locking element 20 and the adapter 4 can be injection-molded without the use of Slides are demolded in the axial direction.
  • the circumferential outer wall 9 of the cover 3 is releasably connected to a piston area 28 of the cover 3, as shown in FIG Fig. 6a, b can be seen.
  • the piston area 28 has a circumferential side wall 30 for resting on the inside of the cylindrical base body 5 of the cartridge 2 and a head area 29 , on the underside of which the receiving area 14 for the adapter 4 is formed.
  • piston area 28 of the cover 3 is shown in the form of the tear-off tape immediately after the circumferential outer wall 9 has been loosened. During the vacuum emptying of the cartridge 2, the piston area 28 is drawn into the base body 5 until the filling substance of the cartridge 2 is completely emptied.
  • Figure 6b shows the piston area 28 of the lid 3, which rests against the underside of the outer bottom area 7c of the cartridge 2 after the filling substance has been completely emptied.
  • Figures 7a, b show an example of a cartridge 2, which differs from that in Fig. la, b shown cartridge 2 characterized in that on the protruding wall portion 10 is formed in a radially outwardly projecting circumferential bead 31.
  • the bead 31 makes it possible to use the cartridge 2 in applications which require the geometry with a bead 31 described in DIN 1284.
  • the bead 31 is in the in Figures 7a, b
  • the example shown is releasably attached to the protruding wall area 10.
  • the bead 31 is connected to the projecting wall area 10 via eight thin spots 32 in the form of tear-off webs, as shown in FIG Figures 8a, b can be seen.
  • the webs 32 enable a point connection of the bead to the protruding wall area 10.
  • the areas between the point-like connections of the bead 31 can be easily grasped by an operator and a sufficiently high pulling force can be exerted.
  • the webs 32 are tapered to a point and form a point-like connection to the protruding wall area 10, so that the bead 31 can be torn off almost without leaving any residue and the sealing effect on the protruding wall area 10 is not impaired.
  • the removal of the bead 31 from the protruding wall area 10 is necessary if the cartridge 2 is to be used for vacuum emptying and the diameter of the cartridge 2 provided with the bead 31 is too large to be introduced into a corresponding emptying system.
  • the bead 31 can also be releasably connected to the cartridge 2 in some other way, for example via a circumferential tearable thin point.
  • the cartridge 2, the cover 3 and the adapter 4 are made of plastic and, in the example shown, are manufactured by injection molding.
  • Polyolefins, in particular polyethylene or polypropylene, have proven to be advantageous as plastic materials.
  • the bottom 7, more precisely the inner bottom region 7b, of the cartridge 2 shown in FIGS. 1 a, b is produced with the aid of what is known as fluid centering, in which a movable inner core of the injection molding tool is centered with the aid of the liquefied plastic material. Due to this production method, the inner base region 7b has an additional thin point on a section of the inner base region 7b that protrudes into the interior of the cartridge 2.
  • the bottom 7 of the in Figures 7a, b In contrast, the cartridge 2 shown was manufactured with a movable inner core and initially star-shaped injection without fluid centering, as is customary, for example, in the manufacture of silicone cartridges.
  • the inner bottom area 7b of the in Figures 7a, b The cartridge 2 shown therefore has no thin point or no section protruding into the interior of the cartridge 2.
