Description

Dispensing tip and dispensing system

FIELD

The present invention relates to a dispensing tip for viscous material comprising a dispensing section with a dispensing opening for dispensing the material, and a base section comprising connecting means for connecting a material source providing the material to be dispended. Further, the present invention relates to a dispensing system for viscous material comprising said dispensing tip, a material source comprising one or more material compartments filled with a viscous material to be dispensed, wherein the material source is connected to the dispensing tip such that each of the one or more material compartments corresponds to one of the one or more transmission paths of the base section and thereby the material provided by the material source can enter the one or more transmission paths of the base section.

BACKGROUND

Dispensing tips for dispensing systems, and corresponding dispensing systems comprising said dispensing tips, exist in different forms and sizes. Especially, properties of said dispensing tips such as for instance shape, hardness, number of openings, etc. can be different for different intended fields of usage. Furthermore, said dispensing tips and dispensing systems can be used in many different applications, like medical applications, dental applications, or industrial applications.

It is known that the intended use of said dispensing tips and dispensing systems, respectively, namely dispensing viscous material, often is not continuous, but interrupted. The interruption time is very variable, from only seconds or even shorter to longer periods like minutes, hours or even days. During said interrupting periods, the viscous material provided still within the dispensing system has to be protected against possibly harmful contact to the environment, for instance by covering a dispensing opening of the dispensing tip.

It is further known that said dispensing systems can be provided already filled with material to the dispensed. In this case, said protection might also be necessary for the storing time of the respective dispensing system, which can be days, month, or even one or several years.

Accordingly, there is a need for dispensing tips and dispensing systems which provide an easy way to protect material stored in the dispensing system before and after usage, and/or also during breaks of usage of the dispensing system.

SUMMARY

The present disclosure provides a dispensing tip and a dispensing system according to the independent claims. Embodiments are given in the subclaims, the description and the drawings.

In one aspect, the present disclosure is directed at a dispensing tip for viscous material comprising a dispensing section with a dispensing opening for dispensing the material and a base section comprising connecting means for connecting a material source providing the material to be dispended, wherein the dispensing section is arranged on the base section, wherein the dispensing section comprises a continuous dispensing path for the material to be dispensed ending at the dispensing opening, wherein the base section comprises one or more continuous transmission paths for the material to be dispensed, whereby the dispensing section and the base section comprise respective bearing means for pivotably arranging the dispensing section on the base section, whereby the dispensing section is pivotable at least between a locking position and a dispensing position, wherein with the dispensing section in the dispensing position, the one or more transmission paths of the base section are connected to the dispensing path of the dispensing section in a flow-communicating manner for forming a continuous flow path through the base section and the dispensing section up to the dispensing opening, and wherein the dispensing section comprises a closing element, whereby with the dispensing section between the dispensing position and the locking position or in the locking position, the one or more transmission paths of the base section are form-fittingly closed by a surface of the closing element.

Dispensing tips are the final part of a dispensing system and actually the part of the dispensing system dispensing the viscous material to be dispensed. In other words, the material is spread and/or applied by the dispensing tip through its dispensing opening, which is mostly arranged at an end of the dispensing tip, into and/or at the intended area and/or volume. A dispensing opening can be a single opening, but also several separated sub-openings are identified as dispensing opening in the sense of the present invention. Preferably, the end of the dispensing tip carrying the dispensing opening can be formed as a functional applicationaid such as for instance a cannula, a swab, or a (micro-)brush.

According to the present invention, the dispensing tip essentially comprises two sections arranged at and on each other, namely a dispensing section and a base section.

The main purpose of the dispensing section is to guide the material to be dispensed from the base section, and hence from the material source, to the intended area or volume. For that, in most cases the dispensing section comprises an elongated shape, with the dispensing opening at and/or near an end of the dispensing section most distant to the base section. Elongated extending in the sense of the present invention covers shapes extending completely straight, but also curved and/or kinked shapes are possible. In addition, the dispensing section comprises a continuous dispensing path, starting at an opening facing the base section and extending up to the dispensing opening.

The main purpose of the base section is to provide connectivity to a material source providing the material to be dispensed. For that, the base section comprises connecting means for connecting said material source. If the material source and the base section are distinct and separate elements, said connecting means preferably ensure a secure and firm fixation of the material source on the base section. However, in the sense of the present invention, also material sources are covered which are at least partly formed integrally with the base section. In such embodiments, the connection means are automatically provided in a transition region between the base section and the material source. In addition, the base section comprises one or more continuous transmission paths. Each transmission path starts at an opening facing, if connected, the material source and extends up a respective opening in a surface of the base section facing the dispensing section.

According to the invention, the dispensing section is pivotably arranged at the base section. For that, both the base section and the dispensing section, respectively, comprise respective bearing means. The respective bearing means of both sections work together and interlock for allowing said pivoting motion of the dispensing section with respect to the base section. Said bearing means can for instance comprise a dome shape of the base section covered by an accordingly shaped recess of the dispensing section, for instance for providing a ball joint-like bearing. Also, other shapes of the bearing means are possible, including axle-like and/or hub-like shapes. In particular, the pivoting motion of the dispensing section covers a range of positions of the dispensing section, including at least a dispensing position and a locking position of the dispensing section. In the dispensing position of the dispensing section, the two sections of the dispensing tip are positioned with respect to each other such that the one or more transmission paths of the base section are connected to the dispensing path of the dispensing section in a flow-communicating manner for forming a continuous flow path through the base section and the dispensing section up to the dispensing opening. In other words, material to be dispensed entering the one or more transmission paths of the base section, can be conveyed through said one or more transmission paths, can enter the dispensing path, can be conveyed through the dispensing path, and finally be dispensed though the dispensing opening.

On the other hand, with the dispensing section in its locking position, and additionally also with the dispensing section between its dispensing position and its locking position, dispensing the material should be prevented. Hence, said continuous flow path should be blocked. For that purpose, according to the invention, the dispensing section comprises a closing element. The closing element preferably is adjacently arranged to the end of the dispensing path facing the base section, and extends such that a surface of the closing element facing the base section slides over the opening of the one or more transmission paths facing the dispensing section, when the dispensing section is pivoted from its dispensing position towards its locking position. Preferably, at least locally around the respective ends of the one or more transmission paths, the corresponding surface of the base section comprises a surface which is formed complementary to the surface of the closing element for enhancing the intended and desired form-fittingly contact. Thereby, the one or more transmission paths of the base section are form-fittingly closed by a surface of the closing element.

In other words, a contact of the viscous material to be dispensed in the material source, and essentially also in the base section, with the environment is always blocked, unless the dispensing section of the dispensing tip according to the in- vention is in its dispensing position. Harmful contact of said material to the environment can thereby be avoided during periods, in which dispensing said material is not intended, for instance in interrupting periods when using the dispensing tip, but also when storing the dispensing tip with a filled material source already attached to it. An especially easy way to protect material stored in a dispensing system comprising a dispensing tip according to the invention before usage and during breaks of usage can thereby be provided.

According to an embodiment, the dispensing section comprises one or more mixing elements arranged within the dispensing path. Said one or more mixing element can be for instance in the form of a T-mixer, a Quadro-mixer or a Helixmixer. Preferably, at least in a section for receiving the one or more mixing elements, the dispensing path can comprise a straight extension. Said mixing element can comprise mixing and/or swirling elements. A mixing element can provide a high smoothness of the dispensed material, preferably without any local fluctuations for instance concerning density. Additionally to that, if the material source provides two or more different materials, a mixing element can further provide a uniform mixing of said two or more materials.

According to an embodiment, the base section comprises a straight and continuous assembly path, whereby the dispensing section is further pivotably arranged on the base section by the bearing means such that the dispensing section is pivotable into an assembly position, which differs from both the locking position and the dispensing position, wherein in said assembly position, the assembly path of the base section is aligned with the dispensing path of the dispensing section for an insertion of the one or more mixing elements through the assembly path into the dispensing path, and whereby further also with the dispensing section between the dispensing position and the assembly position or in the assembly position, the one or more transmission paths of the base section are form-fittingly closed by the surface of the closing element. As mentioned in the last paragraph, one or more mixing elements arranged in the dispensing path of the dispensing section can provide several advantages. By providing an assembly path and constructing the pivotable bearing of the dispensing section on the base section such that the dispensing path in the dispensing section can be aligned with said assembly path, an insertion of said one or more mixing elements through the base section into the dispensing path in the dispensing section can be rendered possible. An according position of the dispensing section with respect to the base section is denoted as assembly position. By additionally ensuring that also with the dispensing section between the dispensing position and the assembly position or in the assembly position, the one or more transmission paths of the base section are form-fittingly closed by the surface of the closing element, unintentional and accidental dispensing of material can thus be avoided.

According to an enhanced embodiment, the assembly position is located between the locking position and the dispensing position. In other words, the locking position and the dispensing position can again and still form the limits of the pivoting motion of the dispensing section. Especially, only in the dispensing position as final position, dispensing the material by the dispensing tip according to the invention is possible. A security against unintentional and accidental dispensing of material can thereby be enhanced.

According to an embodiment, the dispensing section is pivotable with respect to the base section in a range selected between 45° and 90°. If selected between 45° and 90°, the dispensing tip according to the invention can provide a sufficient distance between the locking position and the dispensing position, whereby excessively high requirements on the bearing and/or the bearing means can be avoided. Preferably, the locking position and dispensing position form the limits of the pivoting motion of the dispensing section and thereby span said range. Further, if applicable, the assembly position preferably is located in a center of said range, in the sense of that the pivoting motion starting at the assembly position covers at least essentially the same angle in both the locking position, and the dispensing position, respectively.

According to an embodiment, the base section comprises two or more transmission paths, and wherein the base section and/or the dispensing section comprises at least a part of a combination cavity, wherein in the dispensing position of the dispensing section the combination cavity is completed and arranged between the two or more transmission paths and the dispensing path in a flow-communicating manner, wherein respective ends of the two or more transmission paths and of the dispensing path open into the combination cavity. As already mentioned above with respect to the one or more mixing elements, the source element can provide more than one material, preferably two materials. However, also more than two materials are possible. The two or more materials can be identical, however preferably they are different.

Said two or more materials are dispensed via the single dispensing path in the dispensing section. By providing two or more transmission paths, conveying said two or more materials through the base section can be provided. Before entering the dispensing path, in the currently described embodiment a combining cavity is provided, into which all transmission paths open. Likewise, also the dispensing path opens into said combination cavity. Combining the two or more materials conveyed in the respective transmission paths before entering the single dispensing path can thus be provided.

Said combination cavity can be provided in different ways. On the one hand, the combination cavity can be provided only by the base section as a recess in a surface in which all transmission paths end. Alternatively, the combination cavity can be provided only by the dispensing section as a recess in a surface in which the dispensing path ends. However, also a combination of these possible embodi- merits is feasible, whereby the combination cavity is split in two parts likewise provided as recesses in both the base section and the dispensing section, respectively, whereby the combination cavity is formed by uniting these separate parts when pivoting the dispensing section into its dispensing position.

In summary, during the dispensing process, the two or more materials enter the combination cavity, combine with each other in the combination cavity, and a combination of all materials leave the combination cavity through the dispensing path. A combination of all materials to be dispensed can thereby be provided even before the combined material enter the dispensing path.

According to an embodiment, a longitudinal axis of a part of the dispensing path opening towards the base section extends straight in the dispensing section and/or a longitudinal axis of the one or more transmission path and/or, if applicable, a longitudinal axis of the assembly path, extend straight in the basis section. A straight path suits best for conveying material, as no bends and/or kinks and/or edges obstruct the flow of the material or form locations where material can be deposited. Hence, in this embodiment, conveying the material can be enhanced. However, especially the other end of the dispensing path can provide additional sections in which the dispensing path comprises one or more kinks or bends, in particular adapted to the intended application of the dispensing tip according to the invention.

According to an enhanced embodiment, the longitudinal axis of the one or more transmission paths and, if applicable, the longitudinal axis of the assembly path, are oriented parallel with respect to each other within the base section. An especial dense arrangement of all paths in the base section can thereby be provided. Further, the cross section of said paths in the base section can thereby be maximized. Alternatively, or additionally, according to another enhanced embodiment, with the dispensing section in the locking position and/or in the dispensing position, the longitudinal axis of the part of the dispensing path opening towards the base section is inclined with respect to the longitudinal axis of the one or more transmission paths, and, if applicable, with the dispensing section in the assembly position, the longitudinal axis of the part of the dispensing path opening towards the base section is aligned parallel with respect to the longitudinal axis of the assembly path. Preferably, an inclination angle between of the longitudinal axis of the dispensing path in both the locking position and the dispensing position, respectively, with respect to the longitudinal axis of the transmission paths is the same except different signs. Further, if also an assembly path is provided in the base section, the longitudinal axis of the dispensing path is parallel but miss-aligned with the longitudinal axis of each transmission path in the assembly position.

According to an embodiment, the bearing means provide pivoting the dispensing section with respect to the base section about a single pivoting axis. In other words, the pivoting motion of the dispensing section sweeps across a plane. The construction of the dispensing tip according to the invention can thereby be simplified.

According to a further enhanced embodiment, the pivoting axis is perpendicular with respect to the longitudinal axis of the part of the dispensing path opening towards the base section and/or with respect to the longitudinal axes of the one or more transmission paths and/or, if applicable, with respect to the longitudinal axis of the assembly path. Preferably, the pivoting axis is perpendicular with respect to the longitudinal axes of all listed paths. By that, an alignment of the respective path, preferably of all paths, with the pivoting motion of the dispensing section can be provided easily. According to an embodiment, the base section and the dispensing section both comprise corresponding latching elements for holding the dispensing section with respect to the base section in two or more defined pivoting positions, wherein the defined pivoting position encompass the locking position and the dispensing position and, if applicable, the assembling position. By that, the disposing section is held at least partly in its desired positions by the latching elements. Providing a force by a user to hold the dispensing section in said positions, in particular in the dispensing position, the locking position, and, if applicable, in the assembly position can be avoided. In particular for the locking position, which is the position in which the dispensing tip is usually provided for storage and transport, more than one pair of respective latching elements can be provided to enhance the secure and firm arrangement of the dispensing section in said locking position.

According to an enhanced embodiment, the corresponding latching elements are provided as part of the bearing means. The bearing means are already provided for allowing the pivoting motion on both the base section and the dispensing section, respectively. By adding the latching functionality to said already present elements, building space can be saved and the whole construction of the dispensing tip according to the invention can be simplified. For instance, the bearing means can be formed as axle and hub, and for providing the latching elements, said axle and hub can comprise a rounded star shape, the rounded star spikes accordingly shaped and placed to represent the desired positions of the dispensing section.

According to an embodiment, the dispensing section is injection moulded over the base section. Injection moulding allows providing the dispensing section in a wide variety of different shapes in an especially easy way. As the dispensing section is pivotable with respect to the base section, a tightness of the dispensing tip according to the invention especially at the interface surfaces, at which these sections are arranged at each other, can be enhanced, in particular, the surface of the closing element and the corresponding complementary surface of the base section. Further, also the bearing elements can be provided easily. If applicable, the latching elements can be provided for instance by materials with different hardness for the base section and the over-moulded dispensing section, especially for allowing an elastic deflection of the latching elements.

According to an embodiment, the base section is injection moulded. All general advantages described above with respect to the moulding of the dispensing section can also be provided when moulding the base section. Preferably, both sections, the base section and the dispensing section, respectively, are moulded in a two-component moulding process. In other words, firstly the base section is moulded, and afterwards the dispensing section is moulded over the base section, preferably with a different, for instance harder, material.

In another aspect, the present disclosure is directed at a dispensing system for viscous material comprising a dispensing tip according to one of the preceding claims, a material source comprising one or more material compartments filled with at least a component of the material to be dispensed, wherein the material source is connected to the dispensing tip such that each of the one or more material compartments corresponds to one of the one or more transmission paths of the base section and thereby the material provided by the material source can enter the one or more transmission paths of the base section.

The dispensing system according to the present invention comprises a dispensing tip according to the present invention. All advantages described above with respect to different embodiments of the dispensing tip according to the present invention can also be provided by the dispensing system according to the present invention comprising the respective embodiment of the dispensing tip according to the present invention. Material stored in the one or more material compartments of the material can be conveyed from the material source into the dispensing tip attached and connected to the material source, namely into the one or more transmission paths in the base section of the dispensing tip. Subsequently, the material to be dispensed can be conveyed into and through the dispensing path of the dispensing section up to the dispensing opening. There, the actual dispensing process takes place.

According to an embodiment, the base section and at least the one or more material compartments are formed in one piece. In other words, the connecting means in this embodiment are provided by continuous material in the transition region from the base section to the one or more material compartments. The allocation and also the connection of an according opening of the one or more material compartments to one of the one or more transmission paths of the base section can thereby automatically be provided in an easy way. In particular, the one or more material compartments can also be provided by injection moulding. Further, as the dispensing section of the dispensing tip according to the invention is provided already attached to the base section, this embodiment essentially can be implemented as single use dispensing system, in particular if the one or more material compartment is pre-filled with material to be dispensed.

According to an alternative embodiment, the base section and the material source are formed as two separate pieces. In this embodiment, the connecting means of the base section, preferably matched by corresponding connecting means of the material source, ensure a secure and firm connection and fixation of the material source, and hence of the material compartments of the material source, at the base section of the dispensing tip according to the invention. In other words, the dispensing tip according to the invention can form a dispensing system according to the invention with selected material sources, which essentially can also provide different materials to be dispensed. The application areas of the dispensing system can thereby be enlarged. According to an embodiment, the base section comprises an assembly path and the material source comprises a continuous straight insertion path aligned and connected to the assembly path of the base section. As already described above, in the embodiment of the dispensing tip comprising an assembly path in the base section, inserting one or more mixing elements into the dispensing path of the dispensing section is possible through the base section. By providing a continuous and straight insertion path in the material source aligned and connected to said assembly path, inserting the one or more mixing elements can also be rendered possible with a material source already attached to the base section. This holds true for both embodiments, a base section and material compartments as single-piece, or as separate entities, respectively.

According to an embodiment, the at least the one or more material compartments are deformable, whereby the material source comprises handling areas for applying external pressure to the one or more material compartments. By that, an application of pressure onto the handling areas, for instance simply squeezing the material compartments by hand, can convey the material to be dispensed, from the respective material compartment, through the transmission paths of the base section, and, if the dispensing section is in its dispensing position, into the dispensing path of the dispensing section, and finally through the dispensing opening.

According to an alternative or additional embodiment, the material source comprises one or more pistons, wherein in each of the one or more material compartments one of the one or more pistons is axially movably arranged, wherein the dispensing system further comprises a dispenser apparatus configured to axially move the one or more pistons within the respective material compartment, and wherein the material source comprises coupling means for coupling the material source to the dispenser apparatus. Coupling means in the sense of the present invention can for instance be circumferential flanges on the material source. Said dispenser apparatus usually enables much finer and dosing, especially compared to purely manual squeezing. In particular, the dosing is preferably adjustable, measurable, and/or repeatable. Further, the dispenser apparatus can be re-used with several material sources and dispensing tips according to the invention.

DETAILED DESCRIPTION

Fig. 1 and Fig. 2 depict a possible embodiment of the dispensing tip 10 according to the invention, comprising a dispensing section 20 and a base section 30. Both Fig. 1 , 2, respectively, show a sectional view A and a perspective view B of the dispensing tip 10. In Fig. 1 , the dispensing section 20 is depicted in its dispensing position D, in Fig. 2 in its locking position L. In the following, Fig. 1 , 2 are described together, whereby the special features shown in Fig. 1 , 2 are emphasized.

Preferably, both the dispensing section 20 and the base section 30, are produced via injection moulding, more preferably two-component injection moulding. For that, the base section 30 is moulded first, and afterwards the dispensing section 20 is moulded over the base section 30.

In the depicted embodiment, the upper end of the base section 30 is formed as a dome, and the dispensing section 20 as an accordingly shaped partly spherical shell. By that, the interface regions of the base section 30 and the dispensing section 20 automatically form bearing means 40 allowing a pivoting motion of the dispensing section 20 with respect to the base section 30. In other words, the dispensing section 20 can be pivoted from its dispensing position D (see Fig. 1 ) into its locking position L (see Fig. 2), and vice versa.

The base section 30 comprises at its lower end connecting means 36 for a connection to an external material source 70 (not depicted). Material stored in and conveyed from the material source 70 can enter the base section 30 and be conveyed through the base section 30 through a transmission path 32. Said transmission path 32 is continuous in the base section 30 in the sense that it continuously extends between an opening in the lower end, facing a possibly attached material source 70, up to an upper end of the base section 30 facing the dispensing section 20.

Likewise, the dispensing section 20 comprises a dispensing path 22 continuously extending from a lower end of the dispensing section 20 facing the base section 30, up to a dispensing opening 24 at an upper end of the dispensing section 20. With the dispensing section 20 in its dispensing position D (see Fig. 1 ), the transmission path 32 and the dispensing path 22 are arranged such with respect to each other that they are connected in a fluid communicating way. Hence, material conveyed through the transmission path 32 of the base section 30 enters the dispensing path 22 of the dispensing section 20 and is conveyed up to the dispensing opening 24 for the actual dispensing process.

However, as such dispensing processes are undesired for instance during storage and/or transportation, the dispensing section 20 can also be pivoted into its locking position L (see Fig. 2). In this position, the end of the transmission path 32 facing the dispensing section 20 is no longer connected to the dispensing path 22, but is form-fittingly blocked by an accordingly shaped and arranged surface 28 of a closing element 26 of the dispensing section 20. Material nevertheless present in the transmission path 32 is stopped by this surface 28 and cannot be conveyed further.

In other words, a contact of material to be dispensed in the material source 70, and essentially also in the base section 30, with the environment is always blocked, unless the dispensing section 20 is in its dispensing position D. Harmful contact of said material to the environment can thereby be avoided during periods, in which dispensing said material is not intended, for instance in interrupting periods when using the dispensing tip 10, but also when storing the dispensing tip 10 with a filled material source 70 already attached to it.

Fig. 3, 4 show another possible embodiment of the dispensing tip 10 according to the invention. Fig. 3 depict three sectional views, in which the dispensing section 20 is depicted. Additionally to the dispensing position D (view A) and locking position L (view C), also an assembly position A (view B) of the dispensing section 20 is shown. As depicted, said assembly position A can be arranged between the dispensing position D and the locking position L. In Fig. 4, the dispensing tip 10 is depicted in a perspective view, whereby the dispensing section 20 is in its assembly position A. Again, the dispensing section 20 is pivotably arranged at the base section 30 by respective bearing means 40.

In contrast to the dispensing tip 10 of Fig. 1 , 2, in this embodiment the base section 20 comprises two transmission paths 32. Hence, two materials, in particular different materials, can be conveyed through the base section 30 and finally be dispensed through the dispensing opening 24 of the dispensing section 20. A combination cavity 60, in which both transmission paths 32 and also the dispensing path 22 open, ensures that both materials used during the dispensing process are combined before entering the dispensing path 22.

By a mixing element 50 arranged in the dispensing path 20, a uniform mixing of said two materials can be ensured. For an insertion of said mixing element 50, the base section 20 comprises an assembly path 34 extending straight through the base section 30. As clearly visible in Fig. 3, view B, and in Fig. 4, respectively, the assembly position A of the dispensing section 20 is such that the dispensing path 22 is aligned to said assembly path 34. Thereby, inserting the mixing element 50 through the assembly path 34 of the base section 30 into the dispensing path 22 of the dispensing section 20 is feasible.

Again, the dispensing section 20 comprises a closing element 26 with a surface 28, which form-fittingly blocks all transmission paths 32 of the base section 30. All respective advantages described above with respect to an embodiment with a single transmission path 32 can thereby also be provided for an embodiment of the dispensing tip 10 according to the invention with two or even more transmission paths 32. The following three Fig. 5, 6, 7 depict a possible embodiment of the dispensing system 100 according to the invention, whereby a material source 70, namely two material compartments 72 of said material source 70, is attached to the base section 30 of the dispensing tip 10 according to the invention. In this embodiment, said material compartments 72 and the base section 30 are provided as single piece, preferably produced via injection moulding. In alternative, not depicted embodiments, the material source 70 can also be provided separate from the dispensing tip 10.

Fig. 5 shows an exploded view and Fig. 6 an assembled view, both in perspective. Further, in both Fig. 5, 6, the dispensing section 20 of the dispensing tip 10 is shown in its assembly position A. Fig. 7 show three side views of the dispensing system 100, with the dispensing section 20 in its assembly position A (view A), in its locking position L (view B), and in its dispensing position D (view C), respectively. In the following, Fig. 5, 6, 7 are described together, whereby the special features shown in Fig. 5, 6, 7 are emphasized

In contrast to the embodiments depicted in Fig. 1 to 4, in this embodiment the material source 70, namely two material compartments 72 of said material source 70, are already attached to the base section 30. Said material compartments 72 are closed on a lower end by movable pistons 76. Said lower end also provides coupling means 78 for a coupling to a dispenser apparatus. Said dispenser apparatus is constructed to push the pistons 76 and thereby convey the material stored in the respective material compartment 72. However, also other conveying principles are possible, for instance providing deformable material compartments 72 with handling areas for simply applying external pressure to said material compartments 72.

In the exploded view of Fig. 5, the bearing means 40 are clearly visible, both of the base section 30 and of the dispensing section 20, respectively. As depicted, the bearing means 40 are provided in the form of axle and hub. However, in the present embodiment, said bearing means 40 also provide the functionality of latching elements 42. Therefore, the bearing means 40 are not provided circular, but comprising a rounded star shape, the rounded star spikes accordingly shaped and placed to represent the desired positions L, A, D of the dispensing section 20. Further, the base section 20 is formed of a material softer than the dispensing section 20. Hence, the pivotable motion of the dispensing section 20 can nevertheless be provided, but additionally and as already mentioned above, the bearing means 40 can also provide the functionality of latching elements 42. In other words, the dispensing section 20 is pivotably movable but further held in its locking position L, in its assembly position A, and in its dispensing position D, respectively, without need for external fixation.

In addition to the latching means 42 provided by the bearing means 40, for the locking position L additional and separate latching means 42 are provided. As the dispensing system 100 is stored and transported preferably with the dispensing section 20 in its locking position L, an additional fixation in this specific locking position L can be provided.

As depicted, the material source 70 comprises two material compartments 72. Hence, similar as described above with respect to the embodiment depicted in Fig. 3, 4, a mixing element 50 can be arranged in the dispensing path 22. As the material source 70 is directly attached to the base section 30, a continuous insertion path 74 in the material source 70 aligned and connected to the assembly path 34 in the base section 30 allows an insertion of the mixing element 50 through the material source 70 and the base section 30 into the dispensing path 22 of the dispensing section 20.

In Fig. 7, three different side views of the dispensing system 100 are depicted, namely with the dispensing section 20 in its assembly position A (view A), in its locking position L (view B), and in its dispensing position D (view C), respectively. It is clearly visible that the pivotal motion of the dispensing section 20 covers a range of 90°.
