Description

Technical Field

[0001] This disclosure generally relates to an applicator tip for a dispensing system, a storage component for a dispensing system, and a dispensing system. Background Technology

[0002] Such applicator tips are well known in the art and can be used, for example, in dispensing systems to guide material to the area of ​​application. Therefore, the applicator tip includes a discharge device, such as, for example, a cannula or mixer, which can be connected to a storage component of the dispensing system for discharge operations. The storage component can be, in particular, a container for storing material and a housing configured to hold said container or a shield configured to at least partially receive said housing.

[0003] Furthermore, in such a dispensing system, it is desirable that the applicator tip attached to the storage component can rotate as much as possible around the storage component. This free rotational movement is of particular interest if the applicator tip includes a curved sleeve. The sleeve can then be rotated in the desired position to apply the material. However, the dispensing activator for discharging the material, which can be operated by the user of the dispensing system, remains in a position comfortable for the user. Summary of the Invention

[0004] To ensure the integrity of the connection, it is desirable that the applicator tip be well aligned with the storage component, so that the applicator tip is well positioned on the storage component after assembly. Furthermore, it is desirable that the applicator tip be securely held in the selected rotational position.

[0005] Therefore, an object of the present invention is to enable the applicator tip attached to the storage component to rotate over a large distance. Another object of the present invention is to provide an applicator tip that can be precisely connected.

[0006] These objectives are satisfied by the subject matter of the independent claims.

[0007] The present invention is based on the concept that in a dispensing system comprising an applicator tip connected to a storage component, if at least one of the applicator tip and the storage component includes a connecting member serving as a guide (the guide including a portion extending substantially circumferentially around a longitudinal axis), the applicator tip can rotate over a large distance. In this respect, it should be understood that the corresponding other of the applicator tip and the storage component is preferably constructed in a corresponding manner such that the corresponding other of the applicator tip and the storage component includes a protrusion configured to be guided in the guide of the storage component or the applicator tip in the assembled state of the dispensing system.

[0008] Further advantages and embodiments become apparent from the dependent claims, the specification, and the accompanying drawings.

[0009] Preferably, the protrusion is a radially inwardly projecting protrusion, particularly a protrusion that projects radially inwardly from the inside of the sidewall of the applicator tip. The protrusion may extend at least partially in the circumferential direction. The partial circumferential extension of the protrusion allows the applicator tip attached to the storage component to rotate easily because the contact area between the protrusion and the guide rail is relatively small.

[0010] Alternatively, the protrusion can extend entirely in the circumferential direction. In other words, the protrusion forms a ring-shaped structure, particularly a closed ring-shaped structure. This configuration allows for a secure connection between the applicator tip and the storage component, especially when the annular protrusion is in full contact with the guide rail. Furthermore, particularly if the protrusion and the guide rail are interference-fitted, a selected rotational position of the applicator tip relative to the storage component is firmly held, especially due to the large contact area between the annular protrusion and the guide rail. In this respect, it should be noted that the guide rail extends entirely in the circumferential direction.

[0011] The protrusion may also project radially outward from the outer side of the sidewall. It should be noted that the storage component may then include a guide rail on its inner side to receive the radially outward-projecting protrusion from the tip of the applicator.

[0012] Preferably, the portion of the guide rail extending in the circumferential direction extends at least partially in the circumferential direction. Alternatively, the guide rail may extend entirely in the circumferential direction. This allows for a full 360° range of rotation. Furthermore, a guide rail extending entirely in the circumferential direction allows for receiving protrusions that extend only partially or entirely in the circumferential direction.

[0013] Advantageously, if the applicator tip includes at least two axially extending guide ribs formed on the inner side of the sidewall, the applicator tip can be more precisely connected to the storage component of the dispensing system, wherein at least one of the at least two guide ribs includes a connecting member of the connecting structure. Additionally or alternatively, the connecting member of the connecting structure may be formed in the circumferential direction of the sidewall between the two guide ribs, particularly in the case of guide ribs formed without any connecting member.

[0014] In this respect, during assembly, the storage component is received between guide ribs, and the axially extending guide ribs help to safely guide the applicator tip onto the storage component as it moves axially towards it. Specifically, the guide ribs that receive the storage component prevent unwanted tilting of the applicator tip relative to the storage component and thus function as alignment elements, similar to tolerance sleeves or tolerance rings. This achieves a precise connection of the applicator tip.

[0015] In addition, guide ribs serve as visual markers, thereby ensuring precise alignment during assembly.

[0016] In the assembled state, the connecting member formed on one of the guide ribs interacts with the corresponding connecting structure formed on the storage component, thereby ensuring a secure connection of the applicator tip.

[0017] Preferably, the guide ribs protrude radially inward from the inside of the sidewall.

[0018] At least one guide rib may begin to extend axially from the rear end of the applicator tip and, in particular, may terminate at the inner front end of the applicator tip or at least at the inner side of the front wall. This extension of the guide rib allows for guidance during assembly until the applicator tip is fully positioned on the storage component.

[0019] In a preferred embodiment, a connecting member is formed at the rear end section of the guide rib. This allows the applicator tip to be securely attached to the storage component in the assembled state of the dispensing device.

[0020] To prevent undesirable tilting of the applicator tip during assembly, at least one additional guide rib may be arranged circumferentially offset from the guide rib including the connecting member at an angular position ranging from 10° to 350°.

[0021] If the guide ribs, including the connecting member, and the at least one additional guide rib are arranged on at least substantially diametrically opposite sides of the inner sidewall, tilting of the applicator tip during assembly can be reliably avoided in particular. The arrangement of the guide ribs in their diametrically opposite positions corresponds to an offset angle of 180° between the guide ribs including the connecting member and the additional guide ribs.

[0022] With the aid of examples, reliable tilt prevention can also be achieved by using three guide ribs arranged at an offset angle of at least about 120° between the guide ribs, or by using four guide ribs arranged at an offset angle of at least about 90° between the guide ribs.

[0023] It should be noted that the guide ribs, including the connecting member, and at least one additional guide rib that does not have a connecting member or also includes a connecting member, can be arranged at least substantially 90° to each other on the inner side of the sidewall. This configuration allows the applicator tip to be easily connected to and easily separated from the storage component.

[0024] The guide rib can define an internal space that is configured to receive and store components, wherein the inner surface of the guide rib forms the boundary of the internal space.

[0025] Preferably, the internal space has at least approximately the same dimensions as the external dimensions of the storage component, such that the ribs abut the outer surface of the storage component in the assembled state of the dispensing device. This allows for precise alignment of the applicator tip with respect to the storage component.

[0026] According to another embodiment, the guide ribs can define an internal space that is slightly smaller than the external dimensions of the storage component, thus facilitating an interference fit between the applicator tip and the storage component in the assembled state of the dispensing device.

[0027] The corresponding inner surface of the guide rib facing the internal space can have a shape complementary to the shape of the outer surface of the storage component. This allows for good contact between the applicator tip and the storage component.

[0028] For material discharge, the front wall may include a channel extending through it. Preferably, the channel is formed in a short tube extending axially from the front wall in a direction toward the rear end of the applicator tip. In the fully assembled state, the short tube may be at least partially received in the outlet opening of the container to allow the discharge action.

[0029] The channel in the short tube can also serve as a support for the dispensing device (particularly a sleeve, such as, for example, a curved or flexible sleeve). However, the applicator tip may typically include a sleeve, particularly a curved or flexible sleeve, i.e., not supported by the short tube. It should be understood that the sleeve penetrates the front wall of the applicator tip.

[0030] However, the short tube can also be closed, so that when the applicator tip is connected to the container and the short tube is received in the container's outlet opening, the applicator tip acts as a closing cap.

[0031] If the applicator tip preferably includes at least one axially extending positioning rib formed on the inner side of the sidewall, it facilitates the guidance of the short tube toward the outlet opening of the container during assembly, with the positioning rib offset circumferentially with respect to the guide rib.

[0032] In this regard, it should be noted that the locating ribs can be arranged relative to each other on the inner circumference of the sidewall as described above with respect to the guide ribs. In particular, a locating rib can be circumferentially offset from another locating rib at an angular position ranging from 10° to 350°. Preferably, a locating rib is arranged between two adjacent guide ribs in the circumferential direction of the sidewall.

[0033] Preferably, the positioning rib extends axially from the front wall toward the rear end of the applicator tip, and the axial length of the positioning rib is shorter than the axial length of the guide rib. This reduces the effort required to move the applicator tip onto or from the storage component, because the positioning rib contacts the storage component after the guide rib has contacted it.

[0034] Furthermore, in a preferred embodiment, the axial length of the positioning rib is equal to or longer than the axial length of the short tube. This ensures that the short tube is well guided toward the container's outlet opening during assembly and that the short tube is correctly aligned with the container's outlet opening in the fully assembled state.

[0035] The positioning ribs can protrude radially inward from the inside of the sidewall.

[0036] It should be noted that the positioning ribs can define the internal space configured to receive the storage component, and the inner surface of the positioning ribs forms the boundary of the internal space. The internal space defined by the positioning ribs can have the same or different dimensions as the internal space defined by the guide ribs, particularly smaller or larger dimensions.

[0037] The corresponding inner surface of the positioning rib facing the internal space can have a shape that is complementary to the shape of the outer surface of the storage component.

[0038] It should also be noted that at least one of the positioning ribs may include a connecting member similar to a guide rib.

[0039] The sidewall of the applicator tip may include at least one radially inwardly curved portion and / or at least one radially outwardly curved portion. Preferably, the inwardly curved portion and the outwardly curved portion alternate in the circumferential direction of the sidewall, thereby forming a corrugated outer sidewall.

[0040] Preferably, at least one guide rib is formed in the radially inwardly curved portion of the sidewall and / or at least one guide rib is formed in the radially outwardly curved portion of the sidewall. Similarly, at least one positioning rib may be formed in the radially inwardly curved portion of the sidewall and / or at least one positioning rib may be formed in the radially outwardly curved portion of the sidewall.

[0041] In this respect, if the sidewall is radially resiliently deflectable, as will be described in more detail below, the sidewall of the applicator tip is laterally compressed by applying force to the sidewall (particularly to the radially outwardly curved portion of the sidewall), causing the uncompressed portion of the sidewall to flex radially outward. Preferably, this includes the radially outward flexing of guide ribs of the connecting member.

[0042] After the applicator tip is placed in its desired final position during assembly, the release of force pushes the sidewall back to its original shape, causing the guide rib, including the connecting member, to snap back into its original position, thereby engaging the connecting member of the applicator tip with the corresponding connecting member of the storage component.

[0043] In a corresponding manner, the applicator tip can be released from the storage component by squeezing the sidewall of the applicator tip, which ultimately disengages the applicator tip's connecting member from the corresponding connecting member of the storage component by radially outward deflection of the guide rib, which includes the connecting member.

[0044] Therefore, the radially inward and / or radially outward curved portions formed on the outer sidewall, particularly the corrugations on the outer sidewall, can form a gripping feature. This gripping feature allows for torsional movement of the applicator tip by the user.

[0045] It should be noted that the gripping feature capable of twisting the tip of the applicator can also be formed by at least one fin that protrudes radially from the outer surface of the sidewall, particularly at least one fin that extends axially along the outer surface of the sidewall.

[0046] However, gripping features can also be formed with smooth outer surfaces of sidewalls, for example, if the outer surfaces of the sidewalls include friction-increasing materials, such as soft materials.

[0047] The gripping feature may also be formed by at least one flat portion of the sidewall. Furthermore, the gripping feature may also be formed by combining a flat portion of the sidewall with an arcuate portion of the sidewall. In this respect, the radially outwardly curved portion of the sidewall may correspond to the arcuate portion of the sidewall.

[0048] As indicated above, the guide rib including the connecting member may be radially deflectable. In particular, the guide rib including the connecting member may be spring-resiliently radially deflectable at least at a portion including the connecting member.

[0049] Furthermore, the sidewall may be at least partially spring-resiliently radially deflectable, particularly the portion of the sidewall that includes guide ribs comprising connecting members.

[0050] The elastic deflection of the guide rib and / or sidewall can be achieved, for example, by forming the applicator tip or at least the sidewall of the applicator tip (part of the sidewall having a guide rib including a connecting member) with a spring-elastic material (such as an elastomeric material, such as rubber or silicone).

[0051] However, the spring-elastic behavior of the guide ribs and / or sidewalls can also be achieved from rigid materials (such as thermosetting polymers) by selecting the wall thickness of the sidewalls in a manner that allows for spring-elastic deflection when a predetermined force is applied. This force can correspond to a typical force that can be applied by the user of the dispensing system. Such a typical force is, for example, the force used to squeeze the tip of the applicator with the index finger and thumb.

[0052] If the guide rib, including the connecting member, forms a spring arm, then the elastic deflection of the spring, including the guide rib, including the connecting member, can also be achieved, with the connecting member formed at the spring arm.

[0053] Such a spring arm can be formed of a spring-elastic material or a rigid material. In this regard, it should be noted that if the typical force applied by the user cannot, or at least does not significantly, radially deflect the sidewalls (other than the spring arm), the material and / or wall thickness can be considered rigid when applying pressure to the tip of the applicator laterally, especially when using the thumb and forefinger.

[0054] In a particular embodiment, the spring arm can be configured such that the guide rib including the connecting member is hollowed out at least in the section including the connecting member, thereby forming a cavity between the section including the guide rib and the sidewall. This configuration ensures the integrity of the sidewall, which may be desirable, for example, for applications requiring high hygiene standards.

[0055] According to another embodiment, the spring arm can be formed such that the sidewall includes two axially extending elongated slits, wherein each elongated slit is formed on either side of the guide rib including the connecting member. This configuration allows for easy production of the spring arm.

[0056] In this respect, the elongated slit preferably begins at the rear end of the applicator tip and extends axially toward the front end of the applicator tip. The elongated slit may terminate at the front wall of the applicator tip.

[0057] It should be noted that the narrow slit does not necessarily need to extend completely through the rear end of the applicator to form a spring-loaded arm that can be resiliently deflected radially. It may be sufficient if the sidewall is perforated by a narrow slit that does not extend through the rear end of the applicator tip.

[0058] The connecting member can be formed as a radially inwardly projecting protrusion or a guide rail. It should be understood that the connecting member of the storage component can be formed in other corresponding ways, i.e., as a guide rail or a protrusion, as will be described below.

[0059] The present invention also relates to a storage component, particularly a container, for a dispensing system, the storage component being configured to store material and extending in a longitudinal direction defining a longitudinal axis, the storage component further comprising a connecting member of a connecting structure, the connecting member being a guide rail including a portion extending substantially circumferentially around the longitudinal axis, particularly extending entirely in the circumferential direction, and / or the connecting member being a resiliently deflectable protrusion.

[0060] According to one embodiment, the storage component includes a guide rail having only a portion extending in the circumferential direction. In this respect, this portion of the guide rail may extend at least partially in the circumferential direction. In a preferred embodiment, this portion extends fully in the circumferential direction, for example, in a manner similar to a closed loop. If the applicator tip is attached to the storage component, this allows the applicator tip to rotate completely 360° relative to the storage component.

[0061] According to another embodiment, the guide rail may include a first portion that transitions into the second portion, the first portion extending substantially into or helically inclined relative to the longitudinal axis, and the portion extending substantially circumferentially around the longitudinal axis to form the second portion.

[0062] To achieve a large rotation range, the second part of the guide rail is longer in the circumferential direction than the first part of the guide rail is in the axial direction.

[0063] Preferably, at least one stop is formed in the first portion of the guide rail and / or in the second portion of the guide rail and / or in the region where the first portion transitions to the second portion. Therefore, if the circumferential extension of the guide rail separates from the axial or helical portion of the guide rail by means of the stop, the applicator tip can rotate over a considerable distance. In this context, the stop prevents the protrusion guided in the circumferential extension from accidentally rotating out of the circumferential extension. Thus, the applicator tip can be safely rotated about the container without separation.

[0064] In a dispensing system that includes such a storage component, it is of particular interest that the applicator tip can rotate about its extension axis if the dispensing device is bent. This allows the dispensing device to rotate in a desired position for applying material. However, the dispensing activator for dispensing material, which can be operated by the user of the dispensing system, remains in a position comfortable for the user.

[0065] After the applicator tip has rotated to the desired position, it is preferable that the applicator tip remains in that position. This can be achieved, for example, through an interference fit between the storage component and the guide ribs and / or positioning ribs of the applicator tip, as described above. It should also be noted that the storage component may also include at least one interference structure configured to interact with the applicator tip.

[0066] In the guide rail, the stop member is preferably arranged at the end of the second part of the guide rail.

[0067] The stop member can separate the end of the second part from the first part of the guide rail.

[0068] According to a preferred embodiment, the portion of the stop member facing the first part of the guide rail can be flush with the first part of the guide rail.

[0069] However, according to another preferred embodiment, no stop member is formed in the portion of the guide rail extending in the circumferential direction. This achieves a full 360° rotation range for the applicator tip.

[0070] Preferably, the stop is formed in the end portion where the first part of the guide rail transitions into the second part of the guide rail. In particular, if the circumferentially extending portion of the guide rail does not have a stop member, this stop prevents unwanted separation of the applicator tip.

[0071] The stop can be flush with the second part of the guide rail.

[0072] To allow the applicator tip to rotate within a large range of rotation about the storage component, when the stop is arranged in the first part of the guide rail and the stop member is arranged in the second part of the guide rail, the rotation angle of the second part of the guide rail can be at least 330°, preferably at least 350°, and ideally 360°. According to another embodiment, a stop may be formed in the beginning portion of a second portion that transitions into a first portion of the guide rail. When the stop and the stop member are arranged in the second portion of the guide rail, the rotation angle of the second portion of the guide rail may be at least 270°, preferably at least 280°, and more preferably at least 300°.

[0073] According to yet another embodiment, the guide rail may also be formed without any stops. When the guide rail is formed without any stops and the stop member is arranged in the second part, the rotation angle of the second part of the guide rail is then at least 330°, preferably at least 350°, and ideally 360°.

[0074] Typically, the width of the first part of the guide rail, as seen in the circumferential direction, can be greater than the width of the second part of the guide rail, as seen in the longitudinal direction.

[0075] Correspondingly, the protrusion, especially the protrusion at the tip of the applicator, may have a width corresponding to the width of the first part of the guide rail and a height corresponding to the width of the second part of the guide rail.

[0076] The protrusion can be elastically deflected in the radial direction about the longitudinal axis.

[0077] As described above, the tip of the applicator may include a cannula, and in particular, the cannula is curved or flexible.

[0078] The connection structure preferably allows for one-handed operation. This can be achieved, for example, by means of the grip portion formed at the tip of the applicator.

[0079] The storage component and / or applicator tip may include at least one interference structure, particularly creating an interference fit when the storage component and applicator tip are fully assembled. Such interference structure may be formed, for example, by guide ribs and / or positioning ribs.

[0080] It should be noted that the guide rails and / or protrusions formed at the tip of the applicator can be constructed in the same manner as described herein with reference to the storage component. Similarly, the protrusions and / or guide rails can be constructed in the same manner as described herein with reference to the tip of the applicator.

[0081] It should also be noted that the guide rail can be formed as a groove.

[0082] The present invention also relates to a dispensing system. The dispensing system includes a storage component, particularly as described above, preferably a container, configured to store material and extending in a longitudinal direction defining a longitudinal axis, and an applicator tip, particularly as described above. The applicator tip can be directly connected to the storage component via a connection structure (particularly bayonet type) and / or a form-fit (particularly interference fit) type connection structure.

[0083] The connection structure includes a first connecting member and a second connecting member. The first connecting member is a guide rail formed on the storage component or the tip of the applicator. The second connecting member is a protrusion formed on the corresponding other part of the applicator tip and the storage component. The protrusion is guided by the guide rail when the applicator tip is attached to the storage component. Attached Figure Description

Detailed Implementation

[0085] The multipurpose dispenser 10 and its advantages are described below with reference to the accompanying drawings. Statements regarding orientation and use are made with reference to the drawings.

[0086] The multipurpose dispenser 10 may also be referred to as a dispensing device, dispensing system, or simply dispenser 10, and is typically used for dispensing materials used in medical and dental applications. In particular, the materials that can be dispensed by the multipurpose dispenser 10 may be at least one of, for example, 1K materials, fluids, emulsions, medical fluids, etchants, adhesives, ointments, paints, etc.

[0087] As from Figure 1 As can be seen, the dispenser 10 includes a housing 12. The housing 12 may be formed as a single piece or may include multiple parts.

[0088] The housing 12 may be at least partially received inside the shield 14, which serves as protection against external influences such as fluids, dust, and dirt. Figure 1 The shield 14 shown includes a front portion 14a and a rear portion 14b that can be connected to the front portion 14a. The front portion 14a and the rear portion 14b are connectable, for example by means of a snap-lock connector or a threaded joint. However, the shield 14 can also be formed as a single piece.

[0089] Furthermore, the housing 12 is configured to receive the container 16 at least partially therein.

[0090] The housing 12, the shield 14 and the container 16 each extend in the longitudinal direction defining the longitudinal axis L.

[0091] To prevent undesirable rotational movement of the container 16 about the housing 12 along the longitudinal axis L, at least one of the housing 12 and the container 16 includes a torsion locking part 13, as will be referred to below. Figure 13a and Figure 13b A more detailed, exemplary description follows.

[0092] It should also be noted that the housing 12, the shield 14, and the container 16 each form a storage component. In this respect, the container 16 is a storage component for materials that can be dispensed by the multipurpose dispenser 10. The housing 12 is configured to at least partially receive the container 16, and thus forms a storage component for the container 16. Furthermore, the shield 14 is configured to at least partially receive the housing 12, and thus forms a storage component for the container 16.

[0093] It should also be noted that if container 16 is received in housing 12, housing 12 serves as a storage component for materials that can be dispensed by multipurpose dispenser 10. Similarly, if housing 12 holding container 16 is received in shield 14, shield 14 serves as a storage component for materials that can be dispensed by multipurpose dispenser 10.

[0094] Container 16 can be connected to housing 12 via a bayonet-type connection mechanism. Figure 2 For this purpose, container 16 includes at least one protrusion 106 on its outer circumferential surface, which is guided in an L-shaped groove 118 formed on the inner wall of housing 12 during assembly. The L-shaped groove includes an axial portion 118a extending in the direction of the longitudinal axis L and a circumferential portion 118b extending in the circumferential direction of the inner wall of housing 12.

[0095] In this embodiment, the container 16 includes two protrusions 106 formed on its outer circumferential surface in a diametrically opposed manner. In this context, the housing 12 includes two corresponding L-shaped grooves 118 present in the inner wall of the housing 12.

[0096] In order to securely hold the container 16 inside the housing 12, the container 16 and the housing 12 include a retaining part 120 when assembled.

[0097] The first retaining portion 120a is formed as a radially outward protrusion on the outer peripheral surface of the container 16, while the second retaining portion 120b is formed as a radially inward protrusion on the inner peripheral surface of the housing 12. Furthermore, in the fully assembled state, the first retaining portion 120a of the container 16 rests in a recess 122 formed on the inner peripheral surface of the housing 12.

[0098] As from Figure 2As can be seen along the longitudinal axis L, the first retaining portion 120a is arranged axially adjacent to the protrusion 106. Correspondingly, the second retaining portion 120b and the recess 122 are arranged axially adjacent to the circumferential portion 118b of the L-shaped groove 118.

[0099] To connect container 16 to housing 12, container 16 is axially inserted into housing 12 such that protrusion 106 is guided in the axial portion 118a of recess 118. When container 16 is fully axially inserted, container 16 is then rotated and twisted such that protrusion 106 is guided in the circumferential portion 118b of recess 118 (in... Figure 2 (Counterclockwise direction). Simultaneously, when the container 16 is fully connected to the housing 12, the first retaining portion 120a of the container 16 passes through the second retaining portion 120b of the housing 12 and finally rests in the recess 122. In this state, the retaining portions 120a and 120b prevent the container 16 from rotating backward, thereby securely connecting the container 16 to the housing 12. It should be understood that the container 16 can be removed from the housing 12 by moving it in the reverse manner of the assembly process described above. It should also be noted that the user's hand strength is sufficient to cause the first retaining portion 120a to pass through the second retaining portion 120b.

[0100] Container 16 is configured to store materials, such as those described above.

[0101] It should be noted that, generally speaking, the front part refers to the portion from which material can be discharged from the dispenser 10, while the rear part refers to the portion that is opposite to the front part when viewed in the direction of the longitudinal axis L. Accordingly, the dispensing direction points from the rear part to the front part.

[0102] In order to apply the material dispensed by the dispenser 10 to, for example, a patient's teeth, the dispenser 10 includes an applicator tip 18.

[0103] The applicator tip 18 can be attached to any of the housing 12, the shield 14, or the container 16. In this context, Figure 1 In the middle, the tip 18 of the applicator can be connected to the front part 14a of the shield 14, while Figure 4 An embodiment in which the applicator tip 18 is connected to the container 16 is shown. More on this later... Figure 12 and Figure 13a and Figure 13b Describe the advantageous manner of connecting the tip 18 of the applicator.

[0104] The applicator tip 18 serves as the dispensing outlet of the dispenser 10.

[0105] The applicator tip 18 may also include a sleeve 20. The sleeve 20 allows for more precise application of the material dispensed by the dispenser 10. The sleeve 20 may be bent or bendable independently, as... Figure 1 As shown, or it can be straight, such as Figure 4 As shown. It should be noted that if the material is to be dispensed over an area larger than that within a dental tube or similar, the applicator tip 18 may also be formed without a sleeve.

[0106] Turn now Figure 3 and Figure 5 Further details of the dispenser 10 will be described with reference to other accompanying drawings.

[0107] Dispenser 10 includes a dispensing activator 22 that is movable relative to housing 12. Activation of dispensing activator 22 allows a specific predetermined amount of material to be dispensed from dispenser 10.

[0108] As from Figure 5 As can be best seen, the distributing activator 22 includes a double-arm lever 24. The double-arm lever 24 extends in a direction parallel to the longitudinal axis L and is pivotally supported by a fulcrum 24a, so that the double-arm lever 24 can pivot about a pivot axis P. The pivot axis P is oriented perpendicular to the longitudinal axis L.

[0109] The fulcrum 24a can be formed on the inner wall of the shell 12, or as... Figure 5 It is formed on the support structure 26 as shown. The support structure 26 can be received in the housing 12.

[0110] One arm 28 of the double-arm lever 24 is attached to the button 30, while the other arm 32 of the double-arm lever 24 is configured to drive the drive nut 34 of the rotating mechanism 36. The arm 28 of the double-arm lever 24 attached to the button 30 may also be referred to as the push arm 28, and the other arm 32 of the double-arm lever 24 that can engage with the drive nut 34 may be referred to as the drive arm 32.

[0111] To limit the travel of the double-arm lever 24, the dispenser 10 includes a stop element 27 that interacts with the drive arm 32 of the double-arm lever 24 and stops its travel when the drive arm 32 is stationary at the stop element 27. When the button 30 is pushed radially inward, the stop element 27 ensures that the push arm 28 of the double-arm lever 24 does not collide with the container 16 received in the housing 12. Generally, the stop element 27 limits the travel of the dispensing activator 22 and thus prevents the dispensing activator 22 from colliding with the container 16 received in the housing 12.

[0112] When the drive arm 32 of the double-arm lever 24 reaches the stop element 27, the snap dome 29 attaches to the stop element 27 and provides acoustic feedback. The user then knows that the dispensing activator 22 has been fully activated, allowing the user to release the dispensing activator 22 and reactivate it by pushing the button 30 of the dispensing activator 22 again to further dispense material.

[0113] Furthermore, to ensure the stability and proper function of button 30, button 30 is supported on two longitudinal sides by lever arms. Specifically, button 30 is supported on one side by means of the push arm 28 of double-arm lever 24, and on the opposite side (not shown) by means of the arm of single-arm lever 24. Double-arm lever 24 and single-arm lever are pivotable about the same pivot axis P.

[0114] Furthermore, the double-arm lever 24 and the single-arm lever are arranged on opposite sides of the support structure 26. However, the double-arm lever 24 and the single-arm lever may also be arranged on opposite inner wall sections of the housing 12.

[0115] As described above, the push arm 28 of the double-arm lever 24 interacts with the drive nut 34 of the rotating mechanism 36. For this purpose, the double-arm lever 24 includes a cam (not shown) that projects radially inward toward the drive nut 34 and interacts with ratchet teeth 38 formed on the outer circumferential surface of the drive nut 34.

[0116] When the button 30 of the activator 22 is pushed radially inward relative to the longitudinal axis L ( Figure 5 When arrow B is drawn, the drive nut 34 rotates, causing the drive arm 32 to move in the opposite direction. During this movement of the drive arm 32, its cam engages with one of the ratchet teeth 38 of the drive nut 34, causing the drive nut 34 to rotate about the longitudinal axis L. Figure 5 (Arrow R in the image).

[0117] Spring 35 ( Figure 3 Push the distribution activator 22 back to its initial position so that the distribution activator 22 can be operated again to further rotate the drive nut 34.

[0118] To prevent unwanted rearward rotation of the drive nut 34, the rotating mechanism 36 includes a blocking element 40 that interacts with the drive nut 34. The blocking element 40 is rotationally fixed and functions as a corresponding component for the drive nut 34. The blocking element 40 and the drive nut 34 together form a ratchet.

[0119] Specifically, the drive nut 34 includes additional ratchet teeth 42 formed on the end face of the drive nut 34, which interact with corresponding ratchet teeth 44 formed on the end face of the blocking element 40.

[0120] As from Figure 5 It becomes apparent that the blocking element 40 is connected to the support structure 26. However, the blocking element 40 and the support structure 26 can also be a single piece. That is, the blocking element 40 can be formed at the support structure 26.

[0121] During the rotation of the drive nut 34, its ratchet teeth 42 pass through the ratchet teeth 44 of the blocking element 40. After the rotational movement of the drive nut 34, the engagement between the ratchet teeth 42 of the drive nut 34 and the ratchet teeth 44 of the blocking element 40 prevents the reverse rotational movement.

[0122] To ensure the secure engagement of the ratchet teeth 42 of the drive nut 34 and the ratchet teeth 44 of the blocking element 40, the rotating mechanism 36 includes a spring 46 that axially biases the drive nut 34 toward the blocking element 40 about the longitudinal axis L. The spring 46 is compressed when the ratchet teeth 42 of the drive nut 34 passes the ratchet teeth 44 of the blocking element 40 during rotation of the drive nut 34.

[0123] One end of the spring 46 abuts against the housing 12, while the other end of the spring 46 abuts against the washer 48 disposed between the spring 46 and the drive nut 34. The washer 46 ensures the safe rotational movement of the drive nut 34 during operation.

[0124] Furthermore, the drive nut 34 includes an internal thread that engages with the threaded piston rod 50 of the dispensing mechanism 52. The threaded engagement between the drive nut 34 and the piston rod 50 allows the rotational motion of the drive nut 34 to be transmitted to the rotational motion of the piston rod 50.

[0125] The piston rod 50 also engages with the body nut 54 of the dispensing mechanism 52. For example, the piston rod 50 and the body nut 54 can be threaded together. In this context, it should be noted that the piston 50 can be double-threaded, wherein one thread interacts with the drive nut 34 and the other thread interacts with the body nut 54. Preferably, the respective threads are constructed in reverse order.

[0126] As will be described later, the body nut 54 is rotatably fixed by means of the clutch 56. In the rotatably fixed state, the body nut 54 enables the conversion of rotational motion into translational motion of the piston rod 50, wherein the piston rod 50 moves toward the front end of the distributor 10 in the direction of the longitudinal axis L.

[0127] Specifically, when received in the housing 12, the translational movement of the piston rod 50 causes the front end of the piston rod 50 to contact the plunger 58 stored inside the container 16. Figure 4 Contact. Specifically, when the piston rod 50 contacts the plunger 58, activation of the dispensing activator 22 causes a further translational movement of the piston rod 50, thereby pushing the plunger 58 toward the front end of the container 16, ultimately resulting in the dispensing operation. The plunger 58 is also referred to as piston 58.

[0128] In this regard, it is expected that even if container 16 is installed or reinstalled to be partially emptied or initially only partially filled, distribution from container 16 is directly possible or at least after only a few operation clicks of the distribution activator 22.

[0129] To achieve this, dispenser 10 includes a spring 60 acting on piston rod 50, wherein the spring force of spring 60 is selected such that piston rod 50 is pushed toward plunger 58 of container 16 in the dispensing direction, thereby making dispenser 10 ready for use immediately after insertion into container 16.

[0130] Specifically, the spring 60 acts on the piston rod 50 at one end by means of the transmission element 62, while the other end of the spring 60 abuts against the housing 12, particularly the inner end surface 64 of the housing 12 (see...). Figure 4 and Figure 7 ).

[0131] The transmission element 62 includes a cavity 66 configured to receive the reverse end of the piston rod 50, i.e., the end of the piston rod 50 that is not engaged with the plunger 58. The cavity 66 has a conical shape that enhances the connection between the piston rod 50 and the transmission element 62.

[0132] In addition, the transmission element 62 includes a guide structure 68. The guide structure 68 is radially recessed relative to the collar 72 against which the spring 60 rests.

[0133] As from Figure 4 and Figure 6 As can be seen, when the spring 60 is compressed or decompressed, the guide structure 68 is surrounded by the spring 60 and prevents undesirable tilting of the transmission element 62.

[0134] The rear end 70 of the guide structure also acts as a stop when it contacts the inner end surface 64 of the housing 12, thereby limiting the rearward movement of the piston rod 50.

[0135] exist Figure 7 In the illustrated embodiment, the guide structure 68 has a cross-shaped cross-section. However, the guide structure 68 may also have other cross-sectional shapes, such as a circular cross-section.

[0136] To allow the spring 60 to axially displace the piston rod 50, the distributor 10 includes a clutch 56 that interacts with the body nut 54, such that when the clutch 56 is disengaged, the body nut 54 is allowed to rotate freely, thereby enabling the piston rod 50 to be easily axially displaced by means of the spring force of the spring 60. In other words, the spring 60 pushes the piston rod 50 through the drive nut 34.

[0137] However, when the clutch 56 engages, the body nut 54 is rotated and fixed. Then, the piston rod 50 is no longer axially displaced by the spring 60. In fact, the engagement of the piston rod 50 with both the rotationally fixed body nut 54 and drive nut 34 is prevented from axial displacement of the piston rod 50 solely by means of the spring 60. Therefore, undesirable discharge operations caused solely by the spring 60 are avoided. However, the piston rod 50 can still be axially displaced by means of the rotating mechanism 36 activated by the dispensing activator 22.

[0138] It should be noted that the clutch 56 is fixed in rotation. However, in order to still allow disengagement or engagement with the body nut 54, the clutch 56 can be axially displaced about the longitudinal axis L.

[0139] For guidance during rotational fixation and axial displacement, the clutch 56 includes a guide portion 73 formed on its outer circumferential surface (see in particular). Figure 9b The guide portion 73 is correspondingly guided in the longitudinally extending groove 71 present in the support structure 26. Figure 5 Grooves can also be formed on the inner surface of the housing 12.

[0140] In this embodiment, the clutch 56 includes two guide portions 73 arranged diametrically opposite to each other on the outer circumferential surface of the clutch 56. The clutch 56 may also include only one guide portion 73 or more than two guide portions 73, such as three, four or more guide portions 73.

[0141] The engagement between the body nut 54 and the clutch 56 is achieved through an engagement portion 74 formed on the body nut 54 and a corresponding engagement portion 76 formed on the clutch 56.

[0142] exist Figure 7 In the embodiment shown, the engagement portion 74 of the body nut 54 is formed as a tooth 78 extending radially outward from the circumferential surface of the body nut 54.

[0143] Correspondingly, the engagement portion 76 of the clutch 56 is formed as teeth 80, which extend radially inward into a channel 82 that extends through the clutch 56 and is configured to receive the body nut 54. In particular, the channel 82 of the clutch 56 is dimensionally designed such that, in the engaged state, the body nut 54 is at least partially received therein.

[0144] Furthermore, it should be understood that in the engaged state, the teeth 78 of the body nut 54 mesh with the teeth 80 of the clutch 56, thereby hindering the rotational movement of the body nut 54.

[0145] It should be noted that engagement between the clutch 56 and the body nut 54 is also possible, wherein a tooth in the channel 82 extending into the clutch interacts with a cavity formed in the body nut 54. In a similar manner, the body nut 54 may include radially outwardly extending teeth that interact with the cavity formed in the channel 82 of the clutch 56.

[0146] The body nut 54 and the clutch 56 can also be constructed in the opposite manner, i.e., the body nut 54 may include a channel configured to receive the clutch 56 at least partially therein when the clutch 56 is engaged. In this configuration, when the clutch 56 and the body nut 54 are engaged, at least one tooth and / or at least one cavity is formed in the channel of the body nut 54, interacting with at least one corresponding cavity and / or tooth formed at the clutch 56.

[0147] It should also be noted that other designs for the engagement portions 74 and 76 are possible. For example, the engagement portions 74 and 76 can be formed as rough surfaces on the corresponding end faces of the body nut 54 and the clutch 56, with the corresponding end faces facing each other. Therefore, when the clutch 56 and the body nut 54 are engaged, the frictional force between the engagement portions 74 and 76 is large enough to impede the rotational movement of the body nut 54.

[0148] To ensure that the dispensing operation can only be performed by means of the dispensing mechanism 52, the clutch 56 is engaged by fully inserting the container 16 into the housing 12.

[0149] This is achieved by the following: Container 16 includes at least one ramp feature 84 projecting from its rear side away from container 16. Ramp feature 84 includes a ramp 86 that is helically inclined about the longitudinal axis L. Figure 9a In the illustrated embodiment, container 16 includes two such ramp features 84 arranged in opposite diameters at the rear side of container 16.

[0150] The clutch 56 also includes at least one ramp feature 88 that is complementary to the ramp feature 84 of the container 16. In particular, the ramp feature 88 of the clutch 56 includes a ramp 90 that is helically inclined about the longitudinal axis L in a manner complementary to the ramp 86 of the container 16.

[0151] The ramp feature 88 of the clutch 56 is formed on the end surface of the clutch 56 facing the container 16. Figure 9b In the embodiment shown, the clutch 56 includes two such ramp features 88, which are arranged diametrically opposite each other on the end surface of the clutch 56 facing the container 16 during assembly.

[0152] Engagement of clutch 56 is achieved by inserting container 16 into housing 12 and rotating container 16 about longitudinal axis L. The torsional motion of container 16 ( Figure 10 During the period indicated by arrow T), the ramp feature 84 of container 16 and the ramp feature 88 of clutch 56 come into contact, such that when container 16 is further twisted, ramp 86 of container 16 slides along ramp 90 of clutch 56, which ultimately results in axial displacement of clutch 56 and engagement with body nut 54. Figure 10 Arrow E in the diagram.

[0153] In the fully assembled state, the outermost tips of the corresponding ramp features 84 and 88, as seen in the direction of the longitudinal axis L, are in contact with each other (see...). Figure 10 ).

[0154] During engagement of clutch 56, clutch 56 moves against the spring force of spring 92, which is used to bias clutch 56 away from body nut 54 to disengage it.

[0155] exist Figures 6 to 8 In the illustrated embodiment, the spring 92 is arranged between the blocking element 40 and the shoulder 94 formed at the clutch 56. However, the spring 92 may also abut against the inner wall of the housing 12 instead of the blocking element 40.

[0156] Furthermore, the spring 92 is arranged radially inward relative to the guide 73 of the clutch 56 (see [reference]). Figure 7 and Figure 8 This allows spring 92 to remain securely in place.

[0157] The engagement and dispensing operation of the piston rod 50 with the plunger 58 of the container 16 is achieved as follows.

[0158] When the clutch 56 disengages and allows the body nut 54 to rotate freely, the spring 60 pushes the piston rod 50 toward the front end of the dispenser. As the container 16 is inserted into the housing 12, the piston rod 50 contacts the plunger 58. Upon further insertion of the container 16, the piston rod 50 is pushed in the opposite direction to the dispensing direction (towards the rear end of the dispenser 10), while still remaining in contact with the plunger 58.

[0159] Spring 60 is compressed, and the spring force of spring 60 ensures that piston rod 50 and plunger 58 remain in contact. This contact is maintained when clutch 56 and body nut 54 are engaged, thus allowing for immediate dispensing operation. However, because the frictional force between body nut 54 and piston rod 50 is greater than the spring force of spring 60, dispensing operation is only achieved when dispensing activator 22 is in operation.

[0160] Now for reference Figure 11Further advantages related to the bonding or specialization of components of dispenser 10 are described. This bonding or specialization is desirable because the multi-purpose dispenser 10 can be used with various containers 16 containing different materials (particularly different drugs, adhesives, paints, etc.). However, it is necessary to ensure that the metering is correctly set for each container used.

[0161] Figure 11 An exemplary dedicated mechanism is shown for connecting the correct container 16 to the correct housing 12. However, the dedicated mechanism described herein is also applicable to any other combination of parts of the dispenser 10, including, for example, but not limited to, connections between the applicator tip 18 and / or the container 16 and / or the housing 12 and / or the shield 14.

[0162] exist Figure 11 In the illustrated embodiment, the dedicated mechanism is implemented as a first coding structure 96 formed on the outer peripheral surface of the container 16 and a matching second coding structure 98 formed on the inner wall of the housing 12, in which case the inner wall of the housing 12 is the inner peripheral surface of the inner wall of the housing 12.

[0163] In this embodiment, the first coding structure 96 is formed by a plurality of protrusions and recesses of different widths, while the second coding structure 98 is formed by a corresponding number of recesses and protrusions with complementary widths. Therefore, the container 16 and the shell 12 can only be assembled when the first coding structure 96 and the second coding structure 98 are matched. Figure 11 In the diagram, the encoding structures 86 and 98 are schematically shown as blocks.

[0164] The first coding structure 96 and the second coding structure 98 can also be implemented in another way. With the aid of an example, the first coding structure 96 and the second coding structure 98 can be implemented using typical magnetic modes. It should be understood that the magnetic modes of the first coding structure 96 and the second coding structure 98 are complementary to each other.

[0165] As from Figure 11 As can be seen, both container 16 and shell 12 include a set of two identical coding structures 96 and 98. Within a set of coding structures, the first coding structure is constructed in a point-symmetric manner with respect to the second coding structure of the same set of coding structures.

[0166] It should be noted that this type of encoded structure group can also be used for connections between other parts of the allocator 10.

[0167] To allow for general application, a second coding structure 98 present in the housing 12 can be formed on a ring 100 fixedly connected to the inner circumferential surface of the housing 12. The ring 100 can be removed from the housing 12 using a specified tool and can be replaced by another ring 100 including other coding structures 98. The dispenser 10 can then be used with another container 16 including a matching coding structure 96.

[0168] Furthermore, ring 100 forms part of a bayonet-type connection mechanism, and for this reason, a groove 102 is included in the inner circumferential surface of ring 100. Groove 102 extends parallel to the longitudinal axis L. That is, groove 102 extends parallel to the channel surrounded by ring 100, wherein the channel is configured to receive container 16.

[0169] The other parts of the bayonet-type connection mechanism are formed by circumferentially extending grooves 108 and recesses 104, each formed in the inner circumferential surface of the housing 12. It should be understood that the circumferentially extending grooves 108 and recesses 104 may also be formed in the ring 100, that is, the entire bayonet-type connection mechanism is formed in the ring 100.

[0170] The assembly of container 16 within housing 12 functions as follows.

[0171] If the first coding structure 96 and the second coding structure 98 match, the protrusion 106 formed on the outer peripheral surface of the container 16 passes through the groove 102 of the ring. Figure 11 (See arrow I in the diagram). By twisting the container 16, the protrusion 106 is guided in the channel 108 and eventually comes to rest at the recess 104 in the inner surface of the housing 12. It should be noted that the spring 92, which axially biases the clutch 56 to its front end, also acts on the container 16 via corresponding ramp features 84, 88, thereby bringing the protrusion 106 of the container 16 to rest at the recess 104 of the housing 12. In other words, the spring 92 supports the assembly of the container 16 into the housing 12.

[0172] However, when the container 16 is twisted in the opposite direction to remove it from the housing 12, the spring 92 can also assist in ejecting the container 16 as the protrusion 106 passes through the groove 102, thereby supporting the disassembly of the dispenser 10.

[0173] The protrusion 106 is preferably spring-resiliently deflected in the radial direction relative to the longitudinal axis L. This allows the protrusion 106 to snap into the recess 104 if the container 16 is fully inserted into the housing 12, thereby securely holding the container 16 in the housing 12.

[0174] Now for reference Figure 12 and Figure 13a The text describes an advantageous connection mechanism for connecting the applicator tip 18 to the container 16. In this respect, Figure 13aA first embodiment of container 16 is shown.

[0175] It should be understood that the manner in which the applicator tip 18 is connected to the container 16 as described below also applies to the connection of the applicator tip 18 to the housing 12 or the shield 14, if the connection structure is designed to be similar to the connection structure used with respect to the container 16.

[0176] The applicator tip 18 is dome-shaped and extends longitudinally between the front end 128 and the rear end 130 along the longitudinal extension axis L of the applicator tip 18. It should be noted that, in the assembled state of the dispenser 10, the longitudinal extension axis L of the applicator tip 18 is preferably aligned at least substantially parallel to the longitudinal axis L of the dispenser 10.

[0177] The applicator tip 18 extends to its rear end 130 such that the front portion of the container 16, including the outlet opening, can be received inside the applicator tip 18.

[0178] The front end 128 includes a front wall 132 that transitions into the sidewall 134. The sidewall 134 circumferentially surrounds the extending axis L of the applicator tip 18.

[0179] As from Figure 16 , Figure 19 , Figure 25 The side view depicted in the middle and Figure 22 The cross-sectional view shown provides the best view of the front wall 132, which forms a hollow truncated cone such that the front wall 132 is angled about the longitudinal axis L of the applicator tip 18.

[0180] The sidewall 134 is also angled about the longitudinal axis L of the applicator tip 18, however, at a smaller angle than the front wall 132. In fact, the sidewall 134 is almost parallel to the longitudinal axis L of the applicator tip 18. In this respect, it should be noted that the sidewall 134 may also be parallel to the longitudinal axis L of the applicator tip 18.

[0181] The applicator tip 18 includes a plurality of splines 126 or guide ribs 126 that extend axially in the direction of the extension axis L and project radially inward from the inside of the sidewall 134.

[0182] exist Figure 12 In the illustrated embodiment, the applicator tip 18 includes three guide ribs 126, each circumferentially offset from the other at an angle of approximately 120°. However, the number and angular positions of the guide ribs 126 may also differ. Figure 12 The example shown illustrates this. By way of the example, the applicator tip 18 may include two guide ribs 126 arranged at an angle between each other ranging from 10° to 350°. Preferably, the two guide ribs 126 are arranged on at least substantially diameter-opposite sides inside the sidewall 134, i.e., at an angular position corresponding to 180°.

[0183] With the aid of another example, four guide ribs 126 may be arranged on the inner side of the sidewall 134 such that the angle between two adjacent guide ribs 126 corresponds to at least approximately 90° (see [reference]). Figure 15 , Figure 18 , Figure 21 and Figure 24 ).

[0184] As from Figure 12 and Figure 13a and Figure 13b As can be seen, the applicator tip 18 includes a protrusion 110, which, when connected to the container 16, is guided in a guide rail 112 formed on the outlet side of the container 16 or the head 162. The protrusion 110 and the guide rail 112 are formed together. Figure 13a The bayonet-type connection structure in the middle. Figure 13b In this structure, the protrusion 110 and the guide rail 112 form a shape-fit connection, and depending on the size of the protrusion 110 relative to the guide rail 112, an interference fit connection is formed. For example, from... Figure 13a and Figure 13b It can be further seen that the guide rail 112 is formed as a groove.

[0185] In this regard, it should be noted that the bayonet-type connection structure is an exemplary connection structure, wherein the protrusion 110 forms a first connecting member and the guide rail 112 forms a second connecting member. The protrusion 110 and the guide rail 112 can also be formed together to form a form-fit connection structure. For example, this can be achieved such that the protrusion 110 has a width substantially corresponding to the width of the guide rail 112. The protrusion 110 and the guide rail 112 can also form an interference fit connection structure by forming the width of the protrusion 110 to be slightly larger than the width of the guide rail 112.

[0186] The protrusion 110 can be elastically deflected in the radial direction about the longitudinal axis L.

[0187] It should be noted that protrusions may also be formed at the container 16, and guide rails may be formed at the tip of the applicator 18.

[0188] It should also be noted that the connection mechanism described herein with respect to the applicator tip 18 and the container 16 also applies to the connection between the applicator tip 18 and the housing 12 and / or the shield 14.

[0189] As from Figure 13a As can be seen, the guide rail 112 includes a helically inclined first portion 112a and an extension extending in the longitudinal direction. This orientation of the first portion 112a forces the applicator tip 18 onto the container 16 upon attachment and pushes the applicator tip 18 off the container 16 upon disengagement.

[0190] The second part 112b of guide rail 112 extends circumferentially around the longitudinal axis L. The first part 112a and the second part 112b transition into each other.

[0191] Furthermore, a stop 114 is formed in the guide rail 112 to prevent undesirable separation of the applicator tip 18 from the container 16. However, when a predetermined force is applied, the protrusion 110 can move over and past the stop 114. This force is typically applied by the user manually operating the dispenser 10, i.e., using typical hand force to attach and detach the applicator tip 18 by hand. Preferably, the applicator tip 18 can be attached to or detached from the container 16 by a single-handed operation.

[0192] Specifically, the stop 114 prevents the protrusion 110 guided in the circumferentially extending second portion 112b from moving toward the first portion 112a, causing the applicator tip 18 to accidentally detach from the container 16 during the rotational movement of the applicator tip 18.

[0193] exist Figure 13a In the illustrated embodiment, the stop 114 is formed in the second portion 112b and defines the starting point of the second portion 112b. Specifically, the stop 114 is formed in the second portion 112b, wherein the first portion 112a transitions into the second portion 112b.

[0194] Furthermore, the second part 112b terminates at the stop member 116. The stop member 116 separates the end of the second part 112b from the first part 112a of the guide rail 112.

[0195] In addition, such as from Figure 13a It becomes obvious that the second part 112b of guide rail 112 is longer in the circumferential direction than the first part 112a of guide rail 112 is longer in the axial direction.

[0196] As from Figure 13a As can be seen, the portion of the stop member 116 facing the first portion 112a is flush with the first portion 112a and has the same inclination about the longitudinal axis L as the first portion 112a.

[0197] The stop 114 and the stop member 116 define a rotation angle of at least 270° for the second portion 112b, preferably at least 280°, and more preferably at least 300°. That is, the applicator tip 18 can rotate relative to the container 16 by a rotation angle of at least 270°, preferably at least 280°, and more preferably at least 300°. It is desirable that the applicator tip 18 includes a curved sleeve 20. The sleeve 20 can then be rotated in the desired position to apply material. However, the dispensing activator 22 remains in a position comfortable for the user.

[0198] It should be noted that the guide rail 112 may also be formed without the stop 114. When only the stop member 116 is arranged in the second portion 112b, the rotation angle of the second portion 112b of the guide rail 112 is then at least 330°, preferably at least 350°, and ideally 360°. In this respect, a full rotation angle of 360° is possible if the stop member 116 is not formed in the second portion 112b of the guide rail 112. It should also be noted that the guide rail 112 may include only the stop 114 formed in the first portion 112a and / or the second portion 112b, without any stop member 116.

[0199] However, in order to keep the applicator tip 18 in the desired rotational position, at least one of the container 16 and the applicator tip 18 may include at least one interference structure 124.

[0200] The interference structure 124 causes an interference fit between the container 16 and the applicator tip 18, especially during full assembly.

[0201] exist Figure 12 In the illustrated embodiment, the interference structure 124 is formed by three splines 126, which project radially inward from the inner surface of the applicator tip 18 and extend axially about the longitudinal axis L. The number of splines 126 can vary, i.e., less than three or more than three, such as one spline 126, two splines 126, four splines 126, or five or more splines 126.

[0202] The interference structure 124 may also be provided on the outer circumferential surface of a portion of the container 16 that interacts with the tip 18 of the applicator. In this case, the interference structure 124 may be formed, for example, by a portion that protrudes radially from the container 16.

[0203] Additionally or alternatively, an interference fit can also be achieved through the interaction of the protrusion 110 with the second portion 112b of the guide rail 112. For example, this can be achieved if the width of the protrusion 110, as seen in the longitudinal axis L, is slightly larger than the width of the second portion 122b of the guide rail 112, also seen in the longitudinal axis L.

[0204] In this context, such as from Figure 13a As can be seen, the width of the first portion 112a, as seen in the circumferential direction, is greater than the width of the second portion 112b, as seen in the longitudinal direction L. To ensure safe guidance, the protrusion 110 may be dimensioned to substantially correspond to the dimensions of the first portion 112a and the second portion 112b of the guide rail 112.

[0205] According to another embodiment, which substantially corresponds to the embodiment just described but not shown, the stop 114 is formed in the first portion 112a of the guide rail 112 instead of the second portion 112b. Specifically, it is formed in the end portion of the first portion 112a that transitions into the second portion 112b. Furthermore, in this embodiment, the stop 114 may be flush with the second portion 112b.

[0206] This configuration allows for a rotation angle of almost 360°, limited only by the circumferential dimension of the stop member 116. Therefore, the applicator tip 18 can rotate to even greater degrees.

[0207] According to another embodiment not shown, a stop 114 may also be formed in the region where the first portion 112a transitions to the second portion 112b. It should be understood that, additionally, at least one additional stop 114 may also be formed in at least one of the first portion 112a and the second portion 112b.

[0208] Turn now Figure 13b The second embodiment of container 16 describes another manner in which the applicator tip 18 is connected to container 16. The container 16 of the second embodiment substantially corresponds to... Figure 13a The container 16 of the first embodiment shown.

[0209] Unlike the container 16 of the first embodiment, the container 16 of the second embodiment does not include the spirally extending first portion 112a. Instead, the guide rail 112 includes only the portion extending circumferentially around the longitudinal axis L. In particular, the guide rail 112 extends fully in the circumferential direction, thus forming a closed loop guide rail 112, thereby allowing a full 360° rotation of the applicator tip 18 attached to the container 16. In this respect, it should be noted that no stop member 116 is formed in the circumferentially extending guide rail 112. However, the guide rail 112 may also extend only partially in the circumferential direction, thus having a limited range of rotation.

[0210] In order to attach the applicator tip 18 to Figure 13b The container 16 shown has a protrusion 110 formed at the tip 18 of the applicator that can be radially deflected outward, such that the protrusion 110 moves over the head 162 of the container 16 and eventually snaps into the guide rail 112 to securely hold the tip 18 of the applicator in the container 16.

[0211] In addition, with Figure 13a Compared to the container 16 shown, the torsion locking part 13 is placed in a different position. Specifically, Figure 13b The torsion locking part 13 of the container 16 shown is formed on the outer surface of the body 164 of the container 16. In contrast, Figure 13aThe twist locking part 13 of the container 16 shown is formed at the shoulder 166, which is formed between the recessed head 162 of the container 16 and the body 164 of the container.

[0212] In either case, the corresponding torsion locking portion 13 is formed as a protrusion and configured to interact with a corresponding recess (not shown) formed on the inner sidewall of the housing 12 or the shield 14 to prevent unwanted torsion of the container 16 relative to the housing 12 or the shield 14, respectively. It should be noted that the container 16 may include a recess, and the housing 12 or the shield 14 may include a protrusion to allow torsion locking of the container 16.

[0213] It should also be noted that, if with Figure 13a and Figure 13b The torsion locking part 13 described in conjunction with the container 16 shown may also be additionally or alternatively connected to a corresponding other... Figure 13a and Figure 13b The corresponding other containers 16 shown are used in combination. This also applies to... Figure 13a and Figure 13b The guide rail 112 is shown.

[0214] In the following description, further embodiments of the applicator tip 18 will be referenced in the appendix. Figures 14 to 36 describe.

[0215] Figures 14 to 34 The applicator tip 18 shown corresponds substantially to the applicator tip 18 described above, such that the above description generally also applies to the applicator tip 18 described below.

[0216] However, Figures 14 to 25 The tip of the applicator shown is 18 and Figure 12 The difference of the applicator tip 18 is that a protrusion 110 is formed at one of the guide ribs 126 such that the protrusion 110 protrudes radially inward from that particular guide rib 126.

[0217] It should be noted that a guide rail can be formed on the guide rib 126 instead of the protrusion 110. The guide rail can be constructed in a manner similar to the guide rail 112 described above. Such a guide rail present at the tip 18 of the applicator can be formed, for example, by a guide rib 126 having a large circumferential extension. However, the guide rail can also be segmented and distributed on multiple guide ribs 126. In particular, the second portion of the circumferential extension of the guide rail can be segmented and distributed on multiple guide ribs 126, while the first portion of the axial extension of the guide rail can be formed on only one guide rib 126.

[0218] As from Figure 15 , Figure 18 , Figure 21 and Figure 24As best seen in the rear view depicted, each of the applicator tips includes four guide ribs 126, one of which includes the protrusion 110.

[0219] The four guide ribs 126 are arranged such that the angle between two adjacent guide ribs 126 corresponds to at least substantially 90°.

[0220] Specifically, three additional guide ribs 126 without protrusions are arranged at angular positions of at least substantially 90°, 180° and 270° with respect to the guide ribs 126 including the protrusion 110.

[0221] As already mentioned, the number of guide ribs 126 can vary. However, from the perspective of preventing tilting, it is preferable that the applicator tip 18 has at least one additional guide rib 126 in addition to the guide rib 126 that includes the connecting member.

[0222] As from Figure 15 , Figure 18 , Figure 21 and Figure 24 The rear view shown further reveals that the guide ribs 126 define an internal space in the radial direction between themselves, and the radial internal space is configured to receive storage components, such as container 16.

[0223] The interior space is defined by the inner surfaces 136 of the guide ribs 126, which face the interior space respectively. For example... Figure 15 , Figure 18 , Figure 21 and Figure 24 As shown, the inner surface 136 of the guide rib 126 is arc-shaped to ensure good alignment with the circular outer surface of the container 16 in the assembled state.

[0224] In order to allow the guide rib 126 to be used as the interference structure 124, the internal space defined by the guide rib 126 is slightly smaller than the external dimensions of the container 16.

[0225] This interference connection between the applicator tip 18 and the container 16 allows for maintaining a selected rotational position of the applicator tip 18.

[0226] However, the guide rib 126 not only serves to hold the tip of the applicator 18 in the desired rotational position, but also helps to align the short tube 138, which extends axially rearward from the front wall 132, with the outlet opening of the container 16.

[0227] The short tube 138 includes a channel 140 extending through the front wall 132 and serving as an outlet channel for the applicator tip 18, such as in... Figure 22 As you can see.

[0228] The channel 140 of the short tube 138 is configured as a receiving sleeve. Figures 14 to 25 (not shown), so that the short tube 138 is used as a sleeve socket.

[0229] The short tube 138 is supported by three support structures 142, which extend radially outward from the side surface of the short tube and are based on the inside of the front wall 132.

[0230] The rear end of the short tube 138 includes a rounded edge, which allows the short tube 138 to be repeatedly inserted into the outlet opening of the container 16 without deteriorating the outlet opening of the container 16 or the valve formed in the outlet opening of the container 16.

[0231] To further assist in guiding the short tube 138 toward the outlet opening of the container 16, the applicator tip 18 may include at least one additional positioning rib 144 formed on the inner side of the sidewall 134 (see [link]). Figure 14 , Figure 15 , Figure 17 or Figure 18 ).

[0232] Similar to guide rib 126, positioning rib 144 extends axially from front wall 132 in a direction toward the rear end 130 of applicator tip 18. However, the axial length of positioning rib 144 is shorter than the axial length of guide rib 126, as shown in the image. Figure 14 and Figure 17 This becomes obvious. This ensures that during assembly, the positioning rib 144 contacts the container 16 after the guide rib 126, thereby reducing the force required to attach the applicator tip 18 to the container 16.

[0233] However, the axial length of the positioning rib 144 may be at least the same as or longer than the axial length of the short tube 138 to ensure good guidance of the short tube during attachment of the applicator tip 18.

[0234] The positioning rib 144 has a rounded edge at its respective rear end, which helps to move the applicator tip 18 onto the container 16 during assembly.

[0235] exist Figures 14 to 19 In the illustrated embodiment, the applicator tip 18 includes four positioning ribs 144 circumferentially offset with respect to the guide ribs 126. Specifically, the positioning ribs 144 are arranged between adjacent guide ribs 126 in the circumferential direction of the sidewall 134. Furthermore, the positioning ribs 144 are arranged offset about 45° with respect to the guide ribs 126. It should be noted that the number and position of the positioning ribs 144 can vary. For example, the applicator tip 18 may include only one, two, three, or more than four positioning ribs 144.

[0236] Still referencing Figures 14 to 19As can be seen in the embodiment shown, the positioning rib 144 is formed by the radially outward bending portion 146 of the sidewall 134. Figure 15 ) is formed or formed at the radially inwardly curved portion 148 of the sidewall 134 ( Figure 18 ).

[0237] Guide rib 126 is formed only of the radially inwardly curved portion 148 of the sidewall 134. However, guide rib 126 may also be formed at the radially outwardly curved portion of the sidewall 134 (not shown). It should also be noted that some of the guide ribs 126 may be formed of the radially inwardly curved portion 148 of the sidewall 134, and some other guide ribs 126 may be formed at the radially outwardly curved portion 146 of the sidewall 134.

[0238] The curved portions 146 and 148 of the sidewall 134 cause ripples on the outer side of the sidewall 134, thereby forming the gripping feature 150.

[0239] It should be noted that, Figures 20 to 25 In the illustrated embodiment, similar to Figure 12 The applicator tip shown has a gripping feature 150 formed by a plurality of radially protruding fins 152 extending axially along the outer surface of the sidewall 134.

[0240] Now let's return to the specific design of the guide rib 126, which includes the protrusion 110.

[0241] In order for the protrusion 110 formed at the guide rib 126 to pass through the stop 114 present in the guide rail 112, the guide rib 126 including the protrusion 110 is spring-elastically radially deflected at least in the portion including the protrusion 110.

[0242] This can be achieved, for example, by using a sidewall 134 that is spring-elastically radially deflectable in at least the portion of the sidewall 134 having a guide rib 126 including a protrusion 110.

[0243] Such a resiliently deflectable sidewall 134 can be formed, for example, by using a spring-elastic material. However, the resiliently deflectable sidewall 134 can also be obtained by using a rigid material and selecting its wall thickness, such that the sidewall 134 can be resiliently deflected when a predetermined force (such as a typical force that can be applied by the user of the dispensing system) is applied, particularly by squeezing the tip 18 of the applicator with the thumb and forefinger.

[0244] This method, in which the sidewall 134 is formed of a spring-elastic material and / or the wall thickness of the sidewall 134 is selected such that the sidewall 134 can be radially elastically deflected, is used in... Figures 14 to 16 And in the tip 18 of the applicator shown in 17 to 19.

[0245] However, the spring-elastic radial deflection of the protrusion 110 at the guide rib 126 is also achieved by using a rigid material, since the guide rib 126 including the protrusion 110 forms a radially elastically deflectable spring arm 154, wherein the protrusion 110 is formed at the spring arm 154.

[0246] according to Figures 20 to 22 In the embodiment shown, the spring arm 154 is formed such that the guide rib 126 including the protrusion 110 is axially partially hollowed out in the section including the protrusion 110, thereby forming an axially and radially extending cavity 156 between the rear end section 158 including the protrusion 110 and the sidewall 134 (see...). Figure 22 In this respect, the protrusion 110 is formed at the rear end section 158 of the spring arm 154.

[0247] During assembly or disassembly, the protrusion 110 at the spring arm 154 can be radially deflected outward into the cavity 156.

[0248] Figures 23 to 25 Another way of forming the spring arm 154 is shown in the figure.

[0249] Here, the sidewall 134 is cut by two axially extending elongated cuts 160, such that an elongated cut 160 is formed on either side of the guide rib 126 including the protrusion 110. The resulting spring arm 154 can thus be radially deflected outward about the remaining sidewall 134 during assembly or disassembly.

[0250] As from Figure 23 As can be seen, the elongated slit 160 extends axially from the rear end 130 of the applicator tip 18 and extends toward the front wall 132 of the applicator tip.

[0251] picture Figures 20 to 22 As in the illustrated embodiment, the protrusion 110 is formed at the rear end section 158 of the spring arm 154.

[0252] Figures 20 to 25 The spring arm 154 configuration of the illustrated embodiment redundantly accommodates the positioning rib 144 because, during assembly or disassembly, the spring force applied by the spring arm 154 pushes the spring arm 154 toward the container 16 and thus pushes the guide rib 126 and its protrusion 110 toward the container 16, such that at least the protrusion 110 contacts the container 16. Therefore, the guide rib 126 formed as the spring arm 154, together with other guide ribs 126, allows the applicator tip 18 to be properly aligned with the container 16.

[0253] It should be noted that, regarding Figures 20 to 25 In the embodiment shown, the remainder of the applicator tip 18, excluding the spring arm 154, can be so rigid that the force applied by the user cannot, or at least not significantly, deflect these remainders.

[0254] Turn now Figures 26 to 28 Further embodiments of the applicator tip 18 will be described.

[0255] Figures 26 to 28 The tip 18 of the applicator basically corresponds to Figures 20 to 22 The tip of the applicator shown is 18.

[0256] However, in Figures 26 to 28 In the tip 18 of the applicator, the gripping portion 150 is not formed by a plurality of radially projecting fins 152 extending axially along the outer surface of the sidewall 134. Instead, the gripping portion 150 is formed by two flat portions 168 and two arcuate portions 170 of the sidewall 134, particularly on the outer side of the sidewall 134. In this respect, preferably, the two flat portions 168 and the two arcuate portions 170 are arranged in a diametrically opposed manner. However, the number of flat portions 168 and / or arcuate portions 168 may be different from two, and may be less than or more than two, such as only one flat portion 168 and / or one arcuate portion 170 or three, four or more flat portions 169 and / or arcuate portions 170. Furthermore, the flat portions 168 and arcuate portions 170 may also be arranged in another manner. By way of example, when viewed in the direction of the longitudinal axis L of the applicator tip 18, the three flat portions 168 can be arranged in a triangular manner. Specifically, the applicator tip 18 may then exclude any arcuate portions 170, or the arcuate portions 170 may form rounded corners between the flat portions 168. Furthermore, the dimensions of the flat portions 168 and the arcuate portions 170 in the circumferential direction (circumferential dimensions) can be the same or different. Figures 26 to 28 In the illustrated embodiment, the circumferential dimension of the arcuate portion 170 is larger than the circumferential dimension of the flat portion 168. However, the circumferential dimension of the arcuate portion 170 may also be smaller than the circumferential dimension of the flat portion 168.

[0257] However, in order to form the gripping part 150, the sidewall 134 can also be as described above. Figures 14 to 19 The description is at least partially corrugated. Specifically, the entire sidewall 134 can be as shown in... Figures 14 to 19 The wavy pattern is constructed as described in the context.

[0258] also, Figures 26 to 28 The tip of the applicator 18 and Figures 20 to 22 The difference in the tip of the applicator shown lies in the number of guide ribs 126, including protrusions 110 as connecting members. Specifically, Figures 26 to 28The applicator tip 18 includes two guide ribs 126, each of which is provided with a protrusion 110. In this respect, it should be noted that the protrusion 110 is positioned as follows: Figures 20 to 22 The described method is set at a radially elastically deflectable spring arm 154 formed by a corresponding guide rib 126.

[0259] Guide ribs 126, including protrusions 110, are arranged in the arcuate portion 170 of the sidewall 134 with opposite diameters. That is, guide ribs 126 with protrusions 110 are formed in the radially outwardly curved portion 146 of the sidewall 134.

[0260] Furthermore, guide ribs 126, excluding any connecting members, are arranged in a diametrically opposed manner in the flat portion 168 of the sidewall 134. It should be noted that at least one of the guide ribs 126 in the arcuate portion 170 of the sidewall 134 may not include a connecting member. Furthermore, at least one of the guide ribs 126 in the flat portion 168 of the sidewall 134 may include a connecting member, such as a protrusion 110. Further, the guide ribs 126 in the flat portion 168 of the sidewall 134 may be guide ribs 126 including a connecting member, such as a protrusion 110, while the guide ribs 126 in the arcuate portion 170 of the sidewall 134 may be guide ribs 126 without connecting members.

[0261] The positioning of the guide rib 26, as described above, allows the user to disengage the protrusion 110 from the guide rail 112 by radially inwardly pressing the applicator tip 18 in the region where the corresponding flat portion 168 transitions into the arcuate portion 170 of the sidewall 134. The applicator tip 18 can then be separated from the container 16. Similarly, attachment of the applicator tip 18 to the container 16 can be supported. Therefore, the above-described configuration of the applicator tip allows for intuitive user interaction.

[0262] also, Figures 26 to 28 The applied tip 18 shown includes a positioning rib 144 that is circumferentially offset from the guide rib 126, such as, for example, regarding Figures 14 to 16 or Figures 17 to 19 The tip of the applicator 18 is shown in the illustration.

[0263] As from Figure 27 As can be seen, the positioning rib 144 is placed in the bow-shaped portion 170 near the corner between the bow-shaped portion 170 and the flat portion 168. However, the positioning rib 144 can also be placed in the flat portion 168.

[0264] It should be noted that the number of positioning ribs 144 can vary from four and can be less than or greater than four. It should also be noted that... Figures 26 to 28 The tip 18 of the applicator can be configured to not have any positioning ribs 144.

[0265] from Figure 27 It can be further seen that the guide rib 126, including the protrusion 110, has approximately the same circumferential dimension as the guide rib 126 excluding any connecting members. Furthermore, the positioning rib 144 has a circumferential dimension smaller than that of the guide rib 126. This allows for a good balance between the frictional force that holds the applicator tip 18 in the desired rotational position and the force applied by the user to rotate the applicator tip 18.

[0266] In the following text, we will discuss... Figures 29 to 31 Another embodiment of the applicator tip 18 is described. Figures 29 to 31 The tip 18 of the applicator basically corresponds to Figures 26 to 28 The tip of the applicator is 18. However, with Figures 26 to 28 The tip of the applicator is compared. Figures 29 to 31 The applicator tip 18 does not include any positioning ribs 144. Instead, the circumferential dimension of the guide rib 126, including the protrusion 110, is larger than the circumferential dimension of the guide rib 126 excluding any connecting members (see in particular). Figure 30 In other words, the guide rib 126, including the protrusion 110, forms an arc-shaped wall.

[0267] picture Figures 26 to 28 Like the applicator tip 18, this configuration allows for a good balance between the frictional force that holds the applicator tip 18 in the desired rotational position and the force applied by the user to rotate the applicator tip 18.

[0268] also, Figures 29 to 31 The sidewall 134 of the applicator tip 18 shown can be as follows: Figures 14 to 19 The description is at least partially corrugated. Specifically, the entire sidewall 134 can be as shown in... Figures 14 to 19 The wavy pattern is constructed as described in the context.

[0269] Turn now Figures 32 to 34 Another embodiment of the applicator tip 18 is described. Figures 32 to 34 The tip 18 of the applicator basically corresponds to Figures 29 to 31 The tip of the applicator is 18. However, in Figures 32 to 34 In the tip 18 of the applicator, the circumferential dimension of the guide rib 126, including the protrusion 110, is significantly elongated, such that the guide rib 126 forms a circumferentially closed annular wall. In other words, the two guide ribs 126 including the protrusion 110 (as shown in the image) Figures 29 to 31 (As shown) are connected in the circumferential direction to form a circumferentially closed annular wall.

[0270] This construction makes the guide rib 126 redundant, excluding the connecting member. In this respect, it should be noted that the positioning rib 144 is also unnecessary. It should also be noted that the annular guide rib 126 can be segmented in the circumferential direction by axially extending narrow cuts. Furthermore, the annular guide rib 126 can also be used in conjunction with the corrugated sidewall 134, as per [reference to...]. Figures 14 to 19 Described.

[0271] Like the other guide ribs 126 including the protrusion 110, the annular guide rib 126 including the protrusion 110 is also radially deflectable. In particular, the annular guide rib 126 can be radially outwardly deflected into a cavity 156 formed between the guide rib 126 and the inner side of the sidewall 134.

[0272] It should be noted that sidewall 134 can be as follows: Figures 14 to 19 The description is at least partially corrugated. Specifically, the entire sidewall 134 can be as shown in... Figures 14 to 19 The wavy pattern is constructed as described in the context.

[0273] about Figures 35 to 37 Another embodiment of the applicator tip 18 is described.

[0274] As from Figure 35 and Figure 36 As can be seen, the protrusion 110 is not formed on the inner side of the applicator tip 18, but rather on its outer side. In particular, the protrusion 110 is formed on the outer side of the sidewall 134. Furthermore, the protrusion 110 is formed in the radially inwardly recessed portion of the sidewall 134. This allows for a smooth transition between the outer surfaces of the applicator tip 18 and the storage component in the assembled state.

[0275] As from Figure 35 As can be seen, each protrusion 110 is positioned at a circumferential location corresponding to the flat portion 168 of the sidewall 134.

[0276] However, as Figure 36 As shown, a protrusion 110 can also be positioned at a circumferential location corresponding to the arcuate portion 170 of the sidewall 134.

[0277] Furthermore, the applicator tip 18 may include a protrusion at each circumferential position corresponding to the flat portion 168 and the arcuate portion 170, i.e., is Figure 35 and Figure 36 The combination of applicator tips 18 shown. However, applicator tips 18 may include only at least one protrusion 110 at any circumferential location. It should also be noted that guide rails 112, particularly circumferentially, preferably fully circumferentially, may be located on the outer side of sidewall 134, rather than at least one protrusion 110 or supplementing at least one protrusion 110.

[0278] Furthermore, each protrusion 110 may be positioned at a circumferential location (not shown) corresponding to a guide rib 126 formed on the inner side of the applicator tip 18. That is, the guide rib 126 includes a radially outwardly projecting protrusion. However, the protrusion 110 may also be formed at a circumferential location not corresponding to the guide rib 126, thus making the guide rib 126 a guide rib 126 without a connecting member.

[0279] Figure 35 and Figure 36 The applicator tip 18 shown is configured to connect to a storage component, which in this case is a housing 12, but could also be a shield 14.

[0280] As from Figure 37 It becomes apparent that the housing 12 includes a guide rail 112 on its inner side, the guide rail 112 receiving an outwardly projecting protrusion 110 of the applicator tip 18.

[0281] The guide rail 112 of the housing 12 preferably extends in the circumferential direction about the longitudinal axis L. In particular, the guide rail 112 may extend in the entire circumferential direction to form a closed loop, thereby allowing full 360° rotation of the attached applicator tip 18.

[0282] It should also be noted that Figure 35 or Figure 36 The applicator tip 18 may include at least one additional connecting member formed on its inner side to engage with a corresponding connecting member of the container 16, particularly as described above. Figures 12 to 34 The embodiments shown are described.

[0283] It should also be noted that sidewall 134 can be as follows: Figures 14 to 19 The description is at least partially corrugated. Specifically, the entire sidewall 134 can be as shown in... Figures 14 to 19 The wavy pattern is constructed as described in the context.
