Description

Technical Field

[0001] The present invention relates to a dispensing system, a dispensing outlet for use in a dispensing system, and a cartridge for use in a dispensing system. The dispensing system comprises a dispensing outlet, a valve element, and a cartridge having a cartridge outlet, wherein a longitudinal axis extends along the cartridge outlet, wherein the valve element is slidably arranged at an interface between the cartridge outlet and the dispensing outlet in a direction transverse to the longitudinal axis, and the dispensing outlet can be inserted into the interface to slide the valve element. Background Art

[0002] Dispensing systems exist in a variety of forms and may be used in a wide variety of applications, ranging from dental, medical, veterinary, to industrial applications, among others.

[0003] The dispensing system usually has an outlet which can be connected to a cartridge so that the material stored in the cartridge is directed to the application point via the outlet. If a two-component material is to be dispensed (such as adhesives, paints, molding materials, impression materials, etc.), the outlet part of the dispensing system usually includes a mixer to mix the two components to achieve a more or less ideal dispensing.

[0004] Dispensing systems are usually composed of plastic parts, and in particular, the spout (ie, the mixer) is a disposable part that is discarded after each use. When the spout is discarded, the remaining material to be dispensed also becomes waste.

[0005] After the dispensing system is used and discarded, the material remaining in the cartridge is stored in the cartridge for further use. Summary of the invention

[0006] The object of the present invention is to provide a dispensing system by means of which the life of the material stored in the dispensing system can be increased. A further object of the present invention is to provide a dispensing system that is simple to manufacture and reliable in use. A still further object is to reduce the amount of waste associated with the dispensing system.

[0007] This object is achieved by the subject-matter of the respective independent claims.

[0008] This dispensing system includes a dispensing outlet, a valve element and a cartridge having a cartridge outlet, wherein a longitudinal axis extends along the cartridge outlet, in particular along a direction of dispensing material from the dispensing outlet, wherein the valve element is slidably arranged at an interface between the cartridge outlet and the dispensing outlet in a direction transverse to the longitudinal axis, wherein the valve element is configured to open and close the cartridge outlet to dispense material therefrom, and wherein a portion of the dispensing outlet can be inserted into the interface, in particular for sliding (i.e., driving) the valve element in a direction transverse to the longitudinal axis, for example from a closed position of the valve element to an open position of the valve element, wherein in particular after the dispensing outlet is removed, the valve element automatically shifts back from the open position to the closed position to seal the cartridge outlet.

[0009] By means of such a dispensing system, the opening and closing of the valve element can thus be reliably ensured, thereby increasing the service life of the material stored in the cartridge.

[0010] In this regard, it should be noted that the valve element can be displaced from a closed position when the dispensing outlet is not attached to an open position when the dispensing outlet is attached to permit the material stored in the cartridge to be dispensed from the cartridge. After the cartridge is used and the cartridge outlet is removed, the valve element slides back to the closed position to close the cartridge. In this way, the material stored in the cartridge can be stored for a longer period of time.

[0011] By providing a sliding valve element, rather than a rotating valve element, the force applied to open and close the valve element can be concentrated in one direction, thereby achieving more reliable opening and closing of the cartridge. This means that the sliding valve element does not rotate when it moves.

[0012] In this regard, it should be noted that the dispensing outlet may also be referred to as a static or dynamic mixing tip.

[0013] In this regard, it should be further noted that the cartridge outlet comprises an outlet passage from a corresponding cartridge chamber of the cartridge and is the portion of the cartridge that is configured to be connected to the dispensing outlet.

[0014] In this regard, it should be further noted that the interface includes those portions of the cartridge outlet and the dispense outlet that are configured to cooperate with each other to attach the dispense outlet to the cartridge outlet.

[0015] It should further be noted that a piston and / or a plunger may be arranged in the cartridge in order to dispense the material via the dispensing system in the simplest possible manner.

[0016] As discussed in the foregoing, the valve element is thus able to slide transversely relative to the cartridge from a closed position to an open position and vice versa.

[0017] After the valve element slides laterally from the closed position to the open position relative to the cartridge, the dispensing outlet can be locked to the cartridge outlet to prevent movement along the longitudinal axis. Likewise, once the valve element moves from the open position to the closed position relative to the cartridge, the dispensing outlet can be unlocked to move along the longitudinal axis and in this way be disengaged from the cartridge.

[0018] The valve element may not be removable from the interface. In this regard, it should be noted that the valve element is not removable during normal use of the dispensing system. However, the valve element may be removed by using a tool or if excessive force is applied that would result in damage to the cartridge outlet.

[0019] The valve element can only slide relative to the interface, preferably only along one axis. In this way, the direction in which the valve moves between the open position and the closed position, and vice versa, can be controlled.

[0020] At least one portion of the dispensing outlet can be insertable into the valve element. In this way, the components can cooperate with each other to prevent leakage of material between the cartridge outlet and the dispensing outlet, thereby avoiding contamination therebetween.

[0021] At least one portion may include one or more inlet passages and / or wings. Material may be guided from the cartridge in such an inlet passage to a mixing element (if provided) and to an outlet of a dispensing outlet.

[0022] The dispensing outlet may comprise a cover disc covering the interface. In this way, it is possible to avoid contaminants (such as, for example, dust or discharged mixed material) from dripping from the outlet of the dispensing outlet from reaching the components of the interface.

[0023] The dispensing outlet may further include a collar. Such a collar may further increase contamination resistance.

[0024] The collar may at least partially surround the interface and the cartridge outlet. This is an additional level of contamination resistance that is simple to manufacture.

[0025] The collar can at least partially surround the interface and can be at least partially arranged in the cartridge outlet. In this way, an assembly that is as compact as possible can be achieved.

[0026] The valve element may comprise an elongated plate having one or more through holes. Such a valve element is simple to manufacture and can ensure simple assembly with the cartridge.

[0027] The one or more through holes may be aligned with the cartridge outlet to open the cartridge outlet for dispensing, ie once the valve element is displaced to the open position, the one or more through holes may be aligned with the cartridge outlet to dispense the material stored in the cartridge.

[0028] The cartridge outlet may include one or more cartridge outlet passages. Such cartridge outlet passages allow the material stored in the cartridge to be dispensed in a guided manner.

[0029] The valve element can be slidably arranged to align the one or more through holes with the one or more cartridge outlet passages to open the cartridge outlet for dispensing, and to misalign the one or more through holes with the one or more cartridge outlet passages to close the cartridge outlet. In this regard, it should be noted that in the closed position of the valve element, the through holes do not cover any part of the cartridge outlet passage, and these parts are completely covered by the parts of the valve element that do not have through holes. In this way, when the valve element is in the closed position, the cartridge outlet can be beneficially isolated from the outside.

[0030] The valve element may include a projection extending parallel to the longitudinal axis. Preferably, in the assembled dispensing system, the projection extends toward the dispensing outlet. During use of the dispensing system, such a projection may help to open and close the valve element. In addition, such a projection may also help maintain the valve element in a closed position before and after use of the dispensing system by providing a seal between the valve element and the cartridge.

[0031] The valve element may include one or more protrusions extending along the longitudinal axis toward the cartridge. Such protrusions may help seal the cartridge before and after use of the dispensing system.

[0032] The valve element can be received in one or more passages in the cartridge outlet. Such passages can ensure that the valve element is correctly guided during its sliding movement between the closed position and the open position.

[0033] The projection can be held in one position by a component of the cartridge at the cartridge outlet. In this way, the valve element can be fixed in a closed position, for example during storage of the cartridge of the dispensing system, in order to avoid accidental opening of the valve element. This fixing can be achieved, for example, by a press fit, a form fit, an interference fit, etc.

[0034] The protrusion can be driven by the dispensing outlet to achieve the sliding of the valve element. This design is simple to manufacture and easy to use.

[0035] At least one of the one or more inlet passages may be configured to carry with it at least a portion of the valve element, in particular wherein the projection may be carried with it by at least one of the one or more inlet passages. This design is simple to manufacture and easy to use.

[0036] The component may include one or more arms. Such arms may be used to clamp the projection in the closed position in the simplest possible manner during use of the dispensing system. For example, the arm may include a convex surface facing the projection, which is shaped to complement the outer shape of the projection so as to cooperate with it. The outer shape of the projection may be at least partially cylindrical.

[0037] The one or more inlet passages may each include one or more wings, wherein the one or more wings are configured to engage between the valve element and the component, in particular wherein a respective wing engages between a respective arm and the valve element. Providing mutually cooperating wings and arms at the interface allows the dispensing outlet to be clamped to the cartridge outlet so that the cartridge outlet is reliably held at the cartridge outlet during the dispensing process.

[0038] Each of the wings may include one or more chamfered surfaces. Such chamfered surfaces help guide the dispensing outlet to the cartridge outlet, that is to say allow these two components to be pulled together.

[0039] The one or more protrusions may extend parallel to the sliding direction of the valve element. In this way, the protrusions may help guide the valve element between the open position and the closed position.

[0040] The one or more projections may have a part cylindrical shape.By using a curved surface, the guidance of the valve element in the cartridge outlet may be increased.

[0041] The cartridge outlet may include one or more passages. Providing such passages may help connect the dispensing outlet to the cartridge outlet and / or connect the valve element to the interface.

[0042] One of the projections is received in the one or more channels. In this way, the valve element can advantageously be guided in the cartridge outlet.

[0043] One of the one or more inlet passages may be movable relative to the component. For example, during use of the dispensing system, once the inlet passages have been moved relative to the component, for example into an assembled position, the inlet passages may be locked into position.

[0044] Two components are provided at the cartridge outlet, and two inlet passages are provided, wherein each of the inlet passages is movable relative to a respective one of the components, for example by entering and exiting a respective space formed in one of the components. Such components are simple to manufacture.

[0045] The valve element may include one or more recesses configured to receive at least a portion of the dispensing outlet. Such recesses may ensure that the dispensing outlet is properly placed at the cartridge outlet. In addition, the engagement between the recess and the portion inserted therein may help the valve element shift between an open position and a closed position, and vice versa.

[0046] The dispensing system may further comprise a closure ring arranged at the dispensing outlet, wherein the closure ring comprises a guide groove. Such a closure ring is easily operated by a user of the dispensing system, rotating the closure ring to lock and unlock the dispensing outlet to the cartridge and simultaneously guide the valve element between an open position and a closed position.

[0047] The projection can be forcibly guided in the guide groove, in particular wherein the rotation of the closure ring can be converted into an axial sliding movement of the valve element via the projection and the guide groove. Changing the rotational movement into a sliding movement by means of the guide groove ensures that sufficient force can be provided to open and close the valve element.

[0048] The guide groove can be integrally formed in the closed ring. This design is simple to manufacture and easy to use.

[0049] The guide groove may have a kidney-shaped size. This design is simple to manufacture and easy to use.

[0050] The closure ring may include a blocking element arranged at the inner surface of the closure ring. Such a blocking element may be used to block the closure ring from rotating from an open position to a closed position, for example when no dispensing outlet is attached to the cartridge.

[0051] The interface may comprise a rocking element pivotable about a pivot axis. This rocking element may pivot, ie rock, about the pivot axis.

[0052] The rocking element comprises a first wing and a second wing. Such wings can be configured to cooperate with other parts of the interface in different use conditions of the dispensing system.

[0053] Preferably, the rocking element can be engaged and disengaged from the closure ring, for example to block movement of the closure ring when no dispensing outlet is connected to the cartridge, for example via an interface.

[0054] For this purpose, for example, the second wing can be brought into engagement and disengagement with the closure ring only when the dispensing outlet is inserted into the mouthpiece.

[0055] The rocking element can be brought into engagement and disengagement with a blocking element of the closed ring, for example the second wing can be brought into engagement and disengagement with the blocking element.

[0056] The interface may comprise, for example, a frame protruding in the direction of the dispensing outlet. Such a frame may advantageously be used to receive a dispenser of the dispensing outlet so as to form an alignment device formed on the one hand by an inner shape of the frame and on the other hand by an outer shape of the dispenser, wherein these two corresponding shapes only allow the dispensing outlet to be inserted into the frame of the interface in only one orientation.

[0057] The rocking element can be pivoted between two arms of the frame, wherein a first wing of the rocking element abuts one arm of the frame, for example, as soon as the dispenser has been inserted into the interface.

[0058] In this regard, it should be noted that when inserted into the interface, the dispenser may deflect the rocking element (e.g. the first wing of the rocking element), pivot the rocking element to disengage it from the closed ring (e.g. the blocking element of the closed ring), for example pivot the second wing to disengage from the blocking element.

[0059] The dispensing system may further include a coding alignment device to ensure that the dispensing outlet is placed at the cartridge outlet only in one orientation. In this way, the dispensing outlet can only be placed at the cartridge in one way to ensure reliable use of the dispensing system.

[0060] The inlet passage, through hole and cartridge outlet passage may be arranged non-mirror symmetrically with respect to the longitudinal axis. Such an arrangement may provide a particular type of coding alignment device. Another type of coding alignment device may be provided by the particular design and shape of the distributor, wing and / or arm and the space formed therebetween.

[0061] The cartridge may be a dual-component cartridge including a first cartridge chamber and a second cartridge chamber, and the corresponding materials stored in the corresponding cartridge chambers in the first cartridge chamber and the second cartridge chamber only contact with another corresponding material in the dispensing outlet. In this way, cross contamination at the cartridge outlet can be prevented.

[0062] According to a further aspect, the present invention also relates to a dispensing outlet particularly configured for use with a dispensing system according to the present teachings, i.e., the dispensing outlet can be designed according to one or more specific embodiments disclosed herein, the dispensing outlet comprising: an outlet; a mixing element arranged in a mixer housing, the mixer housing having an outlet coaxially arranged along a longitudinal axis; two inlet passages, each of which comprises one or more wings. The dispensing outlet has the same advantages as those discussed in conjunction with the dispensing system.

[0063] The dispensing outlet may comprise further features as defined herein.

[0064] The dispensing outlet may include an IOR attached at its outlet. Such a dispensing outlet permits the dispensing outlet to be correctly placed at a treatment site, such as a dental patient's tooth cavity, etc.

[0065] The IOR may comprise an inner surface at which one or more inner surface ribs are arranged, and the outer shell comprises one or more outer side ribs arranged at the outer side. In this way, the IOR may be positioned relative to the shell.

[0066] One or more inner surface ribs and one or more outer side ribs can extend parallel to each other.In this way, the dispensing outlet becomes more user-friendly.

[0067] The one or more inner surface ribs may be configured to engage with the one or more outer side ribs.In this way, a predefined position of the IOR relative to the housing may be maintained during use of the dispensing outlet.

[0068] The one or more inner surface ribs and the one or more outer side ribs may extend parallel to the longitudinal axis. In this way, a dispensing outlet that is as compact as possible may be formed.

[0069] The IOR may comprise an inlet. The inlet may comprise one or more circumferentially extending ribs, preferably two circumferentially extending ribs. In this way, the attachment of the IOR at the housing may be facilitated.

[0070] The inlet may comprise one or more apertures, preferably two apertures. In this way, a snap-fit ​​connection may be formed which is easier to manipulate when assembling the dispensing outlet.

[0071] A corresponding rib of the one or more circumferentially extending ribs is arranged at a corresponding orifice of the one or more orifices. In this way, the construction size of the dispensing outlet can be minimized.

[0072] A respective one of the one or more orifices may be arranged downstream of the one or more circumferentially extending ribs when viewed from the inlet opening of the inlet of the IOR.In this way, the configuration size of the dispensing outlet may be minimized.

[0073] An inner surface with one or more inner surface ribs may be arranged at the inlet. In this way, the construction size of the dispensing outlet may be minimized.

[0074] The IOR is non-removably attached to the outer housing, for example via one or more snap-fit ​​connections, preferably via two snap-fit ​​connections. In this way, a connection that is simple to manufacture is used that permits the IOR to rotate relative to the housing while axially securing the IOR to the housing.

[0075] The outer housing may comprise a lip extending in the circumferential direction.In this way, a dispensing outlet which is as compact as possible can be formed, via which a snap-fit ​​connection is possible.

[0076] The static mixer may include a positioning grid that cooperates with two or more positioning grooves arranged in a connector of the static mixer. In this way, alignment between the connector and components of the static mixer may be ensured.

[0077] The housing of the static mixer may comprise an energy carrier which is preferably arranged adjacent to the positioning grid. In this way, the assembly of the dispensing outlet may be simplified.

[0078] The inlet manifold of the static mixer comprises a ledge. In this way, the assembly of the dispensing outlet can be simplified.

[0079] The inlet manifold can be permanently attached to the housing. In this way, a design that is as compact as possible can be ensured even for filigree components.

[0080] The inlet manifold may be permanently attached to the housing via the energy carrier and the flange. In this way, the assembly of the dispensing outlet may be simplified.

[0081] The IOR may include an inlet receiving portion having a body to which a sleeve is attached. For example, the sleeve may be attached to the body at an angle selected within the range of 15 to 75° relative to the longitudinal axis, particularly within the range of 25 to 65° relative to the longitudinal axis.

[0082] By way of example, the cannula may have a passage whose inner diameter is selected in the range of 0.1 to 2 mm. In contrast, the diameter of the housing of the mixing element arranged in the dispensing outlet may have an inner diameter selected in the range of 1 to 12 mm.

[0083] The length of the sleeve can be selected in the range of 5 to 100 mm, in particular in the range of 8 to 60 mm.

[0084] The dispensing outlet as well as the IOR may further comprise a plate connected to the body of the inlet receptacle.Such a plate enables an improved grip of the dispensing outlet.

[0085] The plate can be connected to the main body by one or more material webs. By this connection, material can be saved and the plate can be formed in a simple manner.

[0086] The dispensing outlet as well as the IOR may further comprise a plate which is then connected to the body of the inlet receiver via one or more webs at the portion where the sleeve of the inlet receiver is attached to the body. Such a plate enables an improved grip of the dispensing outlet when it is in use.

[0087] The plate may have a flat outer surface. Such a flat outer surface enables an improved grip of the plate when the dispensing outlet is in use.

[0088] According to a further aspect, the present invention also relates to a cartridge particularly configured for use with a dispensing system having the present teachings, i.e., the cartridge may be designed according to one or more specific embodiments disclosed herein, the cartridge comprising a cartridge outlet, the cartridge outlet comprising a valve element slidably arranged therein, wherein the valve element is arranged between a base of the cartridge outlet and an arm protruding inwardly from an outer wall of the cartridge. The cartridge has the same advantages as those discussed in conjunction with the dispensing system. BRIEF DESCRIPTION OF THE DRAWINGS

[0106] Figure 1a The dispensing system 10 is shown, which includes a dispensing outlet 12 connected to a cartridge outlet 14 of a cartridge 48. The dispensing outlet 12 is connected to the cartridge outlet 14 via an interface 18, see e.g. Figure 2a .

[0107] The dispensing outlet 12 includes a mixer housing 22 having an outlet 28 through which one or more materials M stored in a cartridge 46 can be dispensed. To cover the cartridge outlet 14, the dispensing outlet 12 includes a cover disc 32 connected to a collar 34. The collar 34 partially surrounds the cartridge outlet 14. Figure 1b As shown in FIG. 1 , the collar 34 surrounds three sides of the cartridge outlet 14 .

[0108] The mixer housing 22 includes a connector 26 at its end adjacent to the outlet 26, such as a snap-fit ​​feature 30, via which a particular type of tip can be connected to the dispensing outlet. For example, an intraoral rotation tip (IOR) 64, such as shown in FIGS. 5 , 13 , and 14 , can be connected to the outlet 28 of the dispensing outlet 12.

[0109] The end of the cartridge 48 remote from the cartridge outlet 14 comprises two gripping elements 36, via which the cartridge 46 can be held during use of the dispensing system 10. Figure 1b As shown in FIG. 1 , the plunger 38 is movably arranged in the cartridge 46 so as to engage a piston (not shown) for expelling the material M from the cartridge 46. During use of the dispensing system 100, the user grasps the wings with the fingers of his hand and can apply pressure to the plunger 38 with his or her thumb to push the material M stored in the cartridge 46 out of the cartridge 46.

[0110] When the dispensing outlet 12 is placed at the cartridge 46, the dispensing outlet 12 moves along the longitudinal axis A of the dispensing outlet 12 toward the cartridge outlet 14. Once the dispensing outlet 12 abuts the cartridge outlet 14, it moves in a direction T transverse to the longitudinal axis A, as shown in e.g. Figure 1c This is indicated by arrows provided on the dispensing outlet 12 and the cartridge 46. In this regard, it should be noted that the longitudinal axis A of the dispensing outlet 12 is coaxial with the outlet 28 of the dispensing outlet 12.

[0111] Figure 2a and Figure 2b A cross-sectional view of the dispensing system of FIG1 is shown. A mixing element 20 is arranged in a mixer housing 22. This mixing element 22 can have any shape. For example, a spiral mixing structure can be used, and likewise, a mixing structure called a T mixing structure or a Quadro mixing structure can be used as the structure of the mixing element 20. Such mixing elements are well known in the art and are used to thoroughly mix the multi-component material M.

[0112] Figure 2a The dispensing outlet 12 is shown having been slid axially relative to the cartridge outlet 14 along the longitudinal axis A and then laterally relative to the cartridge outlet.

[0113] Figure 2b The assembled dispensing system 10 is shown once the dispensing outlet 12 has also been moved laterally relative to the dispensing outlet 12 .

[0114] The cartridge 46 has two cartridge chambers 42 for storing respective materials M of the two-component material M, such as a hardener and a corresponding binder.

[0115] The corresponding material M may be dispensed from the corresponding cartridge chamber 42 via the cartridge outlet passage 44 .

[0116] exist Figure 2a In the drawings, the cartridge outlet passages 44 are closed because the valve element 16 covers these passages. The lateral movement of the dispensing outlet 12 causes the lateral sliding movement of the valve element 16 relative to the cartridge outlet passages 44 so as to open these passages by aligning the through holes 40 of the valve element 16 with the cartridge outlet passages 44.

[0117] In this regard, it is noted that the through hole 40 is configured to receive a portion of the inlet passage 24 of the dispense outlet 12 , wherein at least one of the one or more inlet passages 24 is configured to actuate the valve element 16 when the dispense outlet 12 is connected to the cartridge outlet 14 .

[0118] The inlet passage 24 is configured to direct the corresponding material M stored in the corresponding cartridge chamber 42 from the cartridge 46 to the mixing element 20. In the open position of the valve element 16, the inlet passage 24 is aligned with the cartridge outlet passage 44, thereby permitting the material M to be directed.

[0119] In this way, when the valve element is in the open position, the corresponding material M stored in the corresponding cartridge chambers of the first cartridge chamber 42 and the second cartridge chamber 42 contacts another corresponding material M only in the dispensing outlet 12, thereby avoiding cross contamination at the cartridge outlet 14.

[0120] Figure 3a to Figure 3c Various views of a second type of dispensing system 10 are shown, similar to those described above in connection with FIGS. 1 and 2 .

[0121] 1 and 2, the design shown in Fig. 3 has a collar 34 at only one side of the dispensing outlet 12, which covers one side of the cartridge outlet 14. Like the mixing element and housing 22, the valve element 16, interface 18 and connector 26 may be formed identically to one another.

[0122] In this regard, it should be noted that the collar 34 may cover between 5% and 90% of the outer surface of the cartridge outlet 14 , in particular between 10% and 75% of the outer surface of the cartridge outlet 14 , in other words, the collar 34 will not surround the entire outer surface of the cartridge outlet 14 .

[0123] Figure 4a and Figure 4b A further view of the dispensing system 10 of FIG. 3 is shown, highlighting the lateral movement of the dispensing outlet 12 in a direction T transverse to the longitudinal axis A after the dispensing outlet 12 is placed at the cartridge outlet 14 .

[0124] Figure 5a to Figure 5d Various views of a third type of dispensing system 10 are shown, similar to those previously described in connection with Figures 1 and 2. The design differences are that the cartridge 46 has a cylindrical shape rather than a rectangular shape, and the dispensing outlet 12 includes only the cover disc 32, without the collar 34.

[0125] Also shown is a valve element 16 which, like the valve elements of all types of dispensing systems 10 shown herein, cannot be removed from the interface 18 during normal use of the dispensing system. Moreover, like all other valve elements shown herein, the valve element 16 can only slide relative to the interface 18 along only one axis in a direction T transverse to the longitudinal axis A.

[0126] For example, in Figure 4aAs shown in FIG. 8 , a portion of the dispensing outlet 12 is insertable into the valve element 16 , namely the inlet passage 24 with the wing 48 that is commonly formed in the dispenser 80 .

[0127] When sliding the dispensing outlet 12 laterally relative to the cartridge outlet 14 , the distributor 80 is clamped between the base 72 of the cartridge outlet 14 and the part of the cartridge outlet 14 having the arms 50 so as to prevent axial movement of the dispensing outlet 12 relative to the cartridge outlet 14 in the open position of the valve element 16 .

[0128] Figure 5b Show Figure 5a A perspective view of a third type of dispensing system 10 , Figure 5c The dispensing system is shown with the valve element 16 in the closed position (ie before having been slid laterally), and Figure 5d The dispensing system 10 is shown once the dispensing outlet 12 has been slid laterally to the open position of the valve element 16 .

[0129] like Figures 6a to 6c As shown in FIG. 1 , the valve element 16 is received in one or more passages 54 in the cartridge outlet 14 . These passages 54 are shaped to complement the valve element 16 so as to facilitate sliding movement of the valve element 16 relative to the cartridge outlet 14 .

[0130] As shown, the valve element 16 includes a protrusion 52 that protrudes generally in the direction of the longitudinal axis A from the valve element 16 .

[0131] The projection 52 may be held in place by a feature 50 of the cartridge 46 at the cartridge outlet 14, such as Figure 6a , namely held between oppositely disposed arms 50 that project from cartridge wall 74 into cartridge outlet 14. Arms 50 have open ends 84 that are convexly curved to receive cylindrical projection 52 therein in the closed position of valve element 16.

[0132] The projection 52 can be driven by the dispensing outlet 12 to achieve the sliding movement of the valve element 16. The portion of the dispensing outlet 12 configured to drive the projection 52 is an inlet passage 24, which has a portion that is also cylindrical in shape and can be clamped between the male open ends 84 of the oppositely arranged arms 50 in the open position of the valve element 16. Thus, the corresponding inlet passage 24 can move relative to the component 50.

[0133] The valve element includes a protrusion 56 at a side thereof disposed opposite to the side having the projection 52. The protrusion 56 extends parallel to the sliding direction of the valve element 16. The protrusion 56 has a part-cylindrical shape.

[0134] A corresponding one of the projections 54 is received in a corresponding one of the one or more channels 54. The channels 54 are shaped complementary to the projections and in this way also ensure sealing between the valve element 16 and the cartridge outlet 14 in its closed position.

[0135] For example, in Figure 6a As shown in FIG. 1 , two components 50 are provided at the cartridge outlet 14 , and two inlet passages 24 are provided, wherein each of the inlet passages 24 is movable relative to a corresponding one of the components 50 .

[0136] In the closed position of the valve element 16, the curved surfaces of the arms act as hooks, hooking the projection 52 therebetween. When the projection 52 is clamped between the arms 50, the first web 58 is clamped between the base of the cartridge outlet 14 and the arms 50, thereby urging the protrusion 56 into sealing engagement with the passage 54. This interference, so to speak, pushes the valve element 16 toward the cartridge outlet to maintain the closed position.

[0137] In the open position, the valve element 16 is driven by the inlet passage 24 of the dispensing outlet 14 to slide laterally relative to the cartridge outlet 14, thereby releasing the protrusion 52 from the "hook" formed by the curved surface of the open ends 84 of the arms 50. The cylindrical portion of the inlet passage 24 is then positioned between the open ends 84 of the arms 50 and is likewise hooked therebetween, thereby ensuring the correct positioning of the valve element 16 in the cartridge outlet 14.

[0138] Figure 7a and Figure 7b An additional cross-sectional view of the second type of dispensing system 10 is shown. As shown, each inlet passage 24 includes a wing 48, wherein the wing 48 is configured to engage between the valve element 16 and the arm 50. In this regard, it should be noted that the respective wing 48 can be engaged between the respective arm 50 and the valve element 16.

[0139] At this point, it should be noted that such wings 48 and arms 50 may be provided at all types of dispensing systems 10 shown herein.

[0140] To facilitate the introduction of the wings 48 and the engagement of the respective wings 48 under the respective arms, each of the wings 48 may include one or more chamfered surfaces 78. These chamfered surfaces are provided so that axial compression of the dispensing outlet 12 towards the cartridge outlet 14 is also achieved when the wings are guided under the arms.

[0141] Figure 8a to Figure 8h (remove Figure 8c 1 and 2 ) show a view of the valve element 16. As shown, the valve element 16 includes an elongated plate 76 having a through hole 40.

[0142] The valve element 16 includes two recesses 80 arranged parallel to the protrusion 52 , the recesses 80 being configured to receive a respective wing associated with one of the inlet passages 24 .

[0143] The location of these recesses 80 and through holes 40 provide a coded alignment means, thereby ensuring that the dispensing outlet 12 is correctly placed at the cartridge outlet 14 in only one orientation. This is due to the shape and positioning of the corresponding parts.

[0144] like Figure 8a and Figure 8c As shown in FIG. 4 , the through hole 40 and the cartridge outlet passage 44 are arranged in a non-mirror-symmetrical manner relative to the longitudinal axis A.

[0145] like Figure 8b , Figure 8d , Figure 8f and Figure 8h As shown in FIG. 4 , the plate-shaped valve element 16 is arranged with a projection 46 at the side of the valve element 16 opposite to the side having the projection, wherein the through hole 40 extends between the side surfaces.

[0146] Figures 9a to 9f A view of a dispensing outlet of a second type of dispensing system 10 is shown. The inlet passage 24 of the dispensing outlet 12 is likewise arranged non-mirror-symmetrically with respect to the longitudinal axis A. It is positioned complementary to the through hole 40 and the cartridge outlet passage 44 in order to ensure a correct positioning of the inlet passage relative to the cartridge outlet passage 44 in the open position of the valve element.

[0147] As shown in the various views, the wings 48 protrude from the inlet passage 24 in a direction perpendicular to the longitudinal axis A.

[0148] Fig.10a and Fig.10b as well as Fig.11a and Fig.11b A view of a cartridge of a second type of dispensing system 10 is shown. It is configured to be used in conjunction with a valve element 16 as shown in FIG. 8 and a cartridge outlet as shown in FIG. 9 .

[0149] The cartridge 46 includes a cartridge outlet 14 in which a valve element 16 can be slidably disposed. The valve element 16 can be disposed between a base 72 of the cartridge outlet 14 and an arm 50 that protrudes inwardly from an outer wall 74 of the cartridge 46.

[0150] Figures 12a to 12e Various views of a fourth type of dispensing system 10 are shown. The dispensing system 10 further comprises a closing loop 66 arranged at the dispensing outlet 12. Figures 12a to 12c The views shown in are similar to those shown in connection with the third type of dispensing system 10 , in which the dispenser 82 is clamped between the arm 50 and the base 72 of the valve element 16 .

[0151] Fig.12d The dispensing outlet 14 is shown in the open position of the valve element 16 once the closure ring 66 has been rotated.

[0152] Fig.12e The closure ring 66 is shown to include a guide groove 68 formed integrally therewith. To hold the guide groove 68 in place, a web 70 projects from the inner surface of the closure ring 66.

[0153] The projection 52 is positively guided in the guide groove 68. During use of the dispensing system 10 of the fourth type, a rotation of the closing ring 66 is converted via the projection 52 and the guide groove 68 into an axial sliding movement of the valve element 16 in order to displace the valve element 16 from the closed position to the open position and vice versa.

[0154] In order to achieve an opening and closing movement of the valve element 16 , the guide groove 68 has a kidney-shaped size in order to guide the projection 16 of the valve element 16 in a direction T transverse to the longitudinal axis A.

[0155] Fig.13a and Fig.13b Another type of dispensing outlet 12 is shown. Fig.13a A perspective view of the dispensing outlet 12 is shown, and Fig.13b Shown along Fig.13a Cross-sectional view taken along section line A:A.

[0156] The dispensing outlet 12 is configured to be used in the dispensing system 10 as shown in the foregoing. The dispensing outlet 12 includes a mixing element 20 and an IOR 64 disposed in a housing 22. The dispensing outlet 12 can be attached to a cartridge via an interface 18 described in the foregoing in conjunction with any type of dispensing system 10 (see, e.g., Figure 5b ).

[0157] The IOR 64 includes an outlet 63 through which material is dispensed, wherein the outlet 63 is at a first end 67 of a cannula 65 of an intraoral rotation tip (IOR) 64. The first end 67 is disposed opposite a second end 69 of the cannula 65, wherein the cannula 65 is connected to an inlet receiving portion 138 of the IOR 64 at the second end 69.

[0158] Sleeve 65 includes a passage 134 for directing material dispensed from cartridge 46 via dispensing outlet 12 into IOR 64 , through outlet 63 of IOR 64 .

[0159] In this regard, it should be noted that other types of connection means than those described herein may also be employed.

[0160] The IOR 64 is attached to the outer side 112 of the housing 22 such that the IOR 64 can rotate relative to the mixing element 20 but cannot move axially, ie, cannot move along the longitudinal axis A but can rotate about the longitudinal axis A. As shown in FIG.

[0161] The IOR 64 includes an inlet 118 formed in a body 140 of an inlet receiver 138, which is arranged at the end 19 of a dispensing element 12 (e.g., a static mixer or a dynamic mixer). The end 19 of the dispensing outlet 12 is inserted into the inlet 118 of the inlet receiver 138 and snap-fitted into place there via two snap-fit ​​connections 30.

[0162] The end 19 of the outer side 112 of the housing 22 includes a lip 122 extending in the circumferential direction. Fig.13b In the example shown in FIG. 1 , the lip extends completely around the outer side 112 of the housing 22. However, it should be noted that the lip 122 may also include two or more partial lips (not shown). The function of the lip 122 is to provide a portion of the snap-fit ​​connection 120 via which the IOR 64 is attached to the housing 22. The attachment is selected so that the IOR 64 cannot be removed from the housing 22 during its normal use.

[0163] Figures 14a to 14c Show Fig.13a and Fig.13b A view of the intraoral rotating tip 64. Fig.14a , the IOR 64 is attached to the dispensing outlet 12. The IOR 64 includes an inlet receiving portion 138 for attaching the sleeve 65 to the dispensing outlet 12.

[0164] The end 19 of the outer side 112 of the housing 22 is inserted into the inlet 118 .

[0165] The inlet 118 further comprises two orifices 124. These orifices 124 form part of the snap-fit ​​connection 30. In this regard, it should be noted that the snap-fit ​​connection can also be formed without these orifices 124.

[0166] As viewed from an inlet opening 126 of the inlet 118 , the inlet 118 comprises two circumferentially extending ribs 128 , each arranged at one of the orifices 124 , wherein the orifices 124 are arranged downstream of the respective circumferentially extending rib 128 as viewed from the inlet opening 126 .

[0167] When the IOR 64 is snap-fitted into place at the dispensing outlet 12 via the inlet receiver 138, the two ribs 128 engage behind the circumferential lip 122. Thus, the IOR 64 is axially fixed to the dispensing outlet 12.

[0168] The inlet 118 of the IOR 64 includes an inner surface 129 having a plurality of inner surface ribs 130 disposed thereon. Figure 6b The inner surface ribs 130 extend parallel to each other and parallel to the longitudinal axis A.

[0169] like Fig.14c As shown in FIG. 1 , the dispensing outlet 12 has an outlet 28 that is aligned with the passage 134 of the IOR 64 (see FIG. 1 ). Fig.14a ), wherein the material to be dispensed exits outlet 114 and subsequently exits passage 134.

[0170] like Fig.14c As further shown in FIG. 1 , the outer side 112 of the housing 22 includes one or more outer side ribs 132 disposed at the outer side 112. The outer side ribs 132 extend parallel to each other and parallel to the longitudinal axis A.

[0171] The inner surface ribs 130 are configured to engage with the outer side ribs 132. In this manner, the IOR 64 can be rotated about the longitudinal axis A and the dispensing outlet 12. The IOR 64 can be positioned relative to the dispensing outlet 12 depending on the engagement position.

[0172] In this manner, the IOR 64 of the dispensing outlet 12 may be positioned, for example, at a patient's tooth to be treated, and the cartridge attached thereto may be rotated, for example, by a dental professional, to dispense material at a desired angle in a convenient manner.

[0173] Figures 15a to 15c Another type of IOR 64 is shown connected to a dispensing outlet 12 as taught in conjunction with Fig. 1. Naturally, an IOR may be used in conjunction with each dispensing outlet 12 as taught herein.

[0174] The plate 142 is connected to the body 140 of the inlet receiver 138 via a web at the portion of the inlet receiver 138 where the sleeve 65 is attached to the body 140 .

[0175] Plate 142 has a flat outer surface 146 that acts as a finger positioning aid during the dispensing process so that a user can securely hold IOR 64, for example, at a patient's teeth during dispensing.

[0176] The plate 142 is connected to the body by one or more webs of material 144, with the present example having three such webs 144. In this regard, it should be noted that between two and six webs 144 may be provided.

[0177] Figures 16a to 16c Another type of dispensing system 10 is shown. This dispensing system 10 is similar to the design shown in conjunction with FIG.

[0178] The difference is that the closing ring 66 comprises a blocking element 148 which is arranged on an inner surface 150 of the closing ring 66 .

[0179] The interface 18 further includes a rocking element 152 pivotable about a pivot axis 154 , wherein the rocking element 152 includes a first wing 156 and a second wing 158 .

[0180] The rocking element 152 can be engaged and disengaged from the closed ring 66 by a pivoting movement about the pivot axis 154, ie the second wing 158 can be engaged and disengaged from the closed ring 66. Thus, the rocking element 152 can be engaged and disengaged from the blocking element 148 of the closed ring 66.

[0181] The interface 18 further comprises a frame 160 protruding in the direction of the dispensing outlet 12. The frame can be configured to receive the dispenser 80 of the dispensing outlet 12. The inner shape of the frame 160 is adapted to the outer shape of the dispenser 80, wherein these two corresponding shapes only allow the dispensing outlet to be inserted into the frame of the interface in only one orientation, thereby forming a coded alignment device.

[0182] The rocking element 152 is configured to pivot between two arms 162 of the frame 160 , wherein the first wing 156 and the second wing 158 of the rocking element 152 respectively abut one arm 162 of the frame 160 , for example, once the dispenser 80 is inserted into the interface 18 .

[0183] In this regard, it should be noted that when the dispenser 80 and the inlet passage 24 are inserted into the interface 18, a portion of the dispenser 80 is configured to deflect the swing element 152 (for example, the first wing 156 of the swing element 152), pivoting the swing element 152 to disengage it from the closing ring 66, for example, the blocking element 148 of the closing ring 66 is then no longer engaged by the second wing 156 because it is pivoted to disengage from the blocking element 148, in this way the closing ring 66 can be rotated to secure the dispensing outlet to the cartridge 46 and open the valve element 16.

[0184] Thus, the multi-component cartridge 46 can be filled with a material M selected from the group consisting of topical medications, medical fluids, wound care fluids, cosmetic and / or skin care preparations, dental fluids, veterinary fluids, adhesive fluids, disinfecting fluids, protective fluids, paints, and combinations thereof.

[0185] Thus, such material M, and therefore the dispensing system 10, can be advantageously used for treatment of target areas, such as the nose (e.g., antihistamine ointments, etc.), ears, teeth (e.g., molds for implants or cheek applications (e.g., ulcers, gum treatments, canker sores, etc.)), eyes (e.g., precise deposition of medications on the eyelids (e.g., chalazions, infections, anti-inflammatory drugs, antibiotics, etc.)), lips (e.g., herpes), mouth, skin (e.g., antifungal, melasma, acne, warts, psoriasis, skin cancer treatments, tattoo removal medications, wound healing, scar treatments, stain removal, anti-itch applications, etc.), other dermatological applications (e.g., skin nails (e.g., antifungal applications or strengthening formulations, etc.)) or cytological applications.

[0186] Alternatively, the material M, and therefore the dispensing system 10, can also be used in the industrial sector for the production of products and for the repair and maintenance of existing products, for example in the construction industry, the automotive industry, the aerospace industry, the energy industry (for example for wind turbines), etc. The dispensing system 10 can, for example, be used for the dispensing of building materials, sealants, bonding materials, adhesives, paints, coatings and / or protective coatings.
