Description

BACKGROUND

Technical Field

The present disclosure relates to an applicator, in particular to a dental applicator, the applicator comprising an applicator head with an applicator and an elongate body part, wherein the applicator is made from two parts of different material and comprises two kinks, with one of the two kinks being arranged at a part of the applicator where the two different parts at least partially overlap one another. The disclosure further relates to a method of forming an applicator.

Background Information

Applicators are well known, particularly in the dental and medical field for treating e.g. a patient's gums, his teeth, spaces between the teeth or the like. The applicators can be used to apply fluids, such as cremes, medicinal fluids, ointments and the like to parts of a patient's mouth or body.

SUMMARY

For carrying out the various tasks, conventional applicators generally have an application tip that is configured to carry out the precise application. For example, brushes are known for cleaning between a patient's teeth, also foams are also known for applying a dental or medical fluid at an area of the mouth. Particularly with regard to hard to reach areas of the mouth it is desirable to provide an applicator that can be deformed for the specific application and that reliably maintains its shape after deformation.

Moreover, it has been determined that the application tips need to be secured to the handle of the applicator such that neither the application tip nor parts thereof fall off in use of the applicator.

For this reason, it is an object of the present disclosure to provide an applicator that is simple to use, that maintains its shape and form in use and that does not loose parts thereof in use.

This object is satisfied by the subject matter described herein.

For example, such an applicator, in particular a dental applicator, comprises an applicator head with an application tip and an elongate body part, wherein the applicator is made from two parts of different material and comprises two kinks, with one of the two kinks being arranged at a part of the applicator where the two different parts at least partially overlap one another.

By forming the applicator of two parts, in particular only two parts, avoids parts of the applicator from becoming detached during use so that an applicator is made available that does not lose any particles in use.

Moreover, by forming the applicator of two parts of different material, each part can be tailored to its specific use.

For example, the provision of an elongate body part as a handle enables a good tactile control of the application tip during the use of the applicator specifically if this is made of a harder, less flexible material and hence a more robust material than the applicator head.

Moreover, the provision of an applicator head with an application tip that is e.g. integrally formed in one piece with the application tip reduces the number of different components of an applicator and hence reduces the risk of losing parts of the applicator on use thereof.

Such an applicator head formed of a second material can for example be formed of a material that is softer and/or more flexible than a material of the elongate body part and hence be used more effectively for the specific application.

The provision of two kinks enables the production of an applicator that can easily be deformed for the specific use of the applicator so as to reach hard to reach areas in the mouth of a patient.

By forming one of the two kinks in a region of the applicator where the two parts thereof overlap one another provides the applicator with an increased stability at this part of the applicator resulting in an applicator that can be deformed in a shape stable manner, with this change in shape also being maintained during the use of the applicator for improved application results.

One of the two parts made from a different material can be the elongate body part and the other of the two parts made from a different material can be the applicator head, preferably with the applicator head comprising the application tip that is integrally formed thereat. An applicator having such a design is more stable in use and avoids the problems of the prior art associated with losing parts thereof.

Some of the applicator head can overlap some of the elongate body part. In this way an applicator can be formed, e.g. in an injection molding process or an additive manufacturing process with the two parts being non-releasably attached to one another during normal use of the applicator.

A cross-section of the elongate body part along at least a majority of a length of the elongate body part is formed at least substantially by one of a triangle and a Reuleaux triangle or is formed by one of a triangle and a Reuleaux triangle. Forming the applicator in this way ensures that this does not role on a surface on which it is placed causing the application tip from being contaminated in use necessitating the use of a further applicator increasing the time and cost of a treatment.

In this connection a majority means more than half of a length of the elongate body part, specifically more than 70% and preferably more than 85% of a length of the elongate body part.

The application tip can comprise one of a brush with bristles and a foam. Such application tips can be reliably used for different medical and dental applications.

The application tip can be configured to store a liquid thereat. In this way a dental fluid can be introduced into the mouth of a patient for treatment of a target site, or unwanted fluid can be removed from a patient following a successful treatment of the patient. By way of example the application tip can be configured to store between 6 and 15 mg of dental fluid, preferably between 8 and 12 mg of dental fluid.

One of the two kinks can be arranged directly adjacent to that part of the elongate body part that is formed at least substantially by the Reuleaux triangle or the triangle. In this way one of the kinks can be formed at a part made of material that is stable in shape and form even after it has been deformed.

The application tip can be a brush with bristles, with the brush and bristles being formed by at least one of a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU), a thermoplastic vulcanizate (TPV), and a thermoplastic olefin elastomer (TPO). In this way a simple to use applicator can be made available.

By way of example such materials can be Santoprene 8281, further examples of TPE materials that come from block copolymers group are amongst others CAWITON, THERMOLAST K. THERMOLAST M, Amitel, Hytrel, Dryflex, Mediprene, Kraton, Pibiflex, Sofprene, and Laprene. Out of these styrenic block copolymers (TPE-s) are CAWITON, THERMOLAST K. THERMOLAST M, Sofprene, Dryflex and Laprene. Laripur, Desmopan or Elastollan are examples of thermoplastic polyurethanes (TPU). Sarlink, Santoprene, Termoton, Solprene, THERMOLAST V, Vegaprene or Forprene are examples of TPV materials. Examples of thermoplastic olefin elastomers (TPO) compound are For-Tec E, Engage and Ninjaflex.

The two kinks can be configured to be bent in one direction, in particular in only direction, especially such that the application tip can face upwardly relative to the elongate body part. This means that the applicator can be bent in one direction at each kink so that a hook shaped applicator or the like is formed in use providing sufficient degrees of freedom of use of the applicator.

At least one of the two kinks can be configured as a peripherally extending groove, for example, the groove has a round, circular, oval, triangular cross-section transverse to a longitudinal axis of the applicator. The provision of an applicator with such grooves enables the applicator to be bent by 360° relative to the longitudinal axis so that the user thereof can manipulate the position of the application tip for his specific desired use.

The applicator head can be made from a material different from the elongate body part. For example, the applicator head can be made from a material that is softer and/or more flexible than a material of the elongate body part. This means that the applicator head can be tailored to the specific use of the applicator.

The elongate body part can be made from one of polypropylene and polylactide. Such plastics are stable in shape and size also after they have experienced a certain deformation.

The applicator head can comprise a material selected from the group of members consisting of a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU), a thermoplastic vulcanizate (TPV), a thermoplastic olefin elastomer (TPO), polyethylene (PE), polypropylene (PP), poly vinyl chloride (PVC), polyurethane (PU), polystyrene (PS) and combinations of the foregoing. Such thermoplastic elastomers are flexible and soft in use for, e.g. dental applications and also permit the storage of fluid thereat.

The applicator head can be configured to receive a part of the elongate body part. This means that parts of the elongate body part can extend into and possibly through some of the applicator head for improved attachment of the applicator head at the elongate body part.

The part of the elongate body part received within the applicator head can comprise one or more centering elements, for example, two groups of centering elements are provided that are axially spaced apart from one another. The centering elements enable the precise positioning of the applicator head at the elongate body part and can also provide a security against rotation in order to prevent a rotation of the applicator head relative to the elongate body part.

One of the kinks can be arranged at that part of the applicator head and that part of the elongate body part that is received within the applicator head. In this way the second kink is also provided in that part of the applicator that has the harder and more rigid material properties than the applicator head.

The application tip can be a foam application tip made from an open cell foam having pores. Such an application tip can be used to distribute dental or medical fluids in an expedient manner.

The applicator can further comprise an undulating surface or the like. Such an undulating surface can act as a grip for holding the applicator. In this connection it should be noted that other forms of grip can likewise be provided that have enable an improved gripping of the applicator in use.

The undulating surface can cover between 5 and 30%, preferably between 10 and 25% of the outer surface of the elongate body part. In this way a length of the grip can be selected such that it approximately amounts to a length corresponding to between 1 to 3 widths of fingers of a user of the applicator.

The undulating surface can comprise a plurality of peaks and valleys. Such undulating surfaces are simple to manufacture e.g. in an injection molding process.

The applicator can comprise one or more first points of injection. These can beneficially be formed at that part of a mold used to form the elongate body part.

The one or more first points of injection can be disposed at the elongate body part. In this way a material of the elongate body part can be injected into a corresponding mold at that part of the mold designed for the elongate body part in such a way that a material of the elongate body part does not have to flow through non-desirable regions of the mold.

One of the one or more first points of injection can be disposed at the undulating surface. Since the structure of such an undulating surface can be more filigree than that of the elongate body part it can be necessary to provide a point of injection at a position that corresponds to that part of the mold where the undulating surface is formed, such that the material can flow more easily into the part of the mold shaped for molding the undulating surface, i.e. the grip.

One or more second points of injection can be provided. These can preferably be designed for injecting a second kind of material into the mold of the applicator.

By way of example, the one or more second points of injection can be disposed at the applicator head. In this way the second points of injection can beneficially be arranged at a position where the injection mold injects the material for the applicator head.

Beneficially the one or more second points of injection can be disposed at the kink arranged at the applicator head. In this way the material of the applicator head can flow more easily around the kink and possibly also in the region of at least one of the first and second types of centering element.

According to a further aspect the present disclosure relates to a method of forming an applicator, in particular a dental applicator, the applicator comprising an applicator head with an application tip and an elongate body part, wherein the applicator is made from two parts of different material and comprises two kinks, with one of the two kinks being arranged at a part of the applicator where the two different parts at least partially overlap one another, the method comprising the steps of injection molding the elongate body part and then injection molding the applicator head with parts of the applicator head being overmolded onto parts of the elongate body part.

In this way the applicator can be manufactured in a fast, facile and cost effective manner.

In this connection it should be noted that a width of the second type of centering elements 32 along the longitudinal axis A can be selected in the range of 0.1 to 10 mm, preferably in the range of 0.5 to 5 mm.

The second type of centering elements 32 are arranged between the application tip 14 and the first kink 18.

Both the first and second types of centering elements 30, 32 are formed as rectangular structures that engage the applicator head and prevent a movement thereof relative to the elongate body part 16.

On forming the applicator head 12 over the elongate body part 16 one forms a continuous outer surface 44 of the applicator 10, with an outer part of the second type of centering elements 32 forming a part of the continuous outer surface 44.

The applicator head 12 tapers in diameter between the second kink 20 and the application tip 14.

FIG. 3A shows a side view of the elongate body part 16 and FIG. 3B shows a perspective view of a connecting portion 36 of the elongate body part 16. The applicator head 12 is injection molded over the elongate body part 16 over the length of the connecting portion. A length of the connecting portion 36 is selected as 10 to 30% of a length L of the elongate body part 16 between the front end 40 and the rear end 38.

FIGS. 4A and 4B show enlarged views of the triangular shape of the applicator 10, with FIG. 4A showing the application tip 14 attached and FIG. 4b showing the application tip 14 removed from the elongate body part 16.

The first kink 18 is arranged at the connecting portion 36, i.e. at that part of the applicator 10 where the applicator head 12 is overmolded onto the elongate body part 16, whereas the second kink 20 is arranged only at the elongate body part 16.

Both the first and second types of centering elements 30, 32 project from an outer surface 42 of the connecting portion 36.

The first type of centering elements 30 are arranged transverse to the second type of centering elements 32 and also transverse to a longitudinal axis A of the applicator 10 that extends in parallel to the main direction of extent of the applicator 10. By arranging the first and second types of centering elements 30, 32 transverse to one another a security against rotation can be improved.

The second type of centering elements 32 are arranged in parallel with the longitudinal axis A of the applicator 10.

The two types of centering elements 30, 32 are arranged axially spaced apart from one another, with the second type of centering elements 32 being arranged between the first type of centering elements 30 and the second kink 22.

In this connection it should be noted that a spacing between the first and second types of centering elements 30, 32 along the longitudinal axis A can be selected in the range of 0.1 to 5 cm, preferably in the range of 0.5 to 3 cm.

In the shown examples two first types of centering elements 30 and two second types of centering elements 32 are provided in respective groups, with each centering element 30, 32 of a respective group being arranged at opposite sides of the elongate body part 16.

In this connection it should be noted that between 1 and 4 of such first and second types of centering elements 30, 32 can respectively be provided, i.e. one of each our of each or one first and four second types of centering elements 30, 32.

The second kink 20 is arranged directly adjacent to that part of the elongate body part 16 that is formed at least substantially by the Reuleaux triangle.

The two kinks 18, 20 are configured to be bent in one direction while being able to be bent at any angle in the radial direction by 360° relative to the longitudinal axis. The triangular shaped body permits the applicator 10 to lie on a flat surface without rolling off and the applicator 10 can be placed onto the flat surface with the application tip 14 facing away from the flat surface, i.e. relative to the elongate body part 16.

The first and second kinks 18, 20 are each configured as a peripherally extending groove 22. The groove 22 can have one of a round, circular, oval, and triangular cross-section transverse to a longitudinal axis A of the applicator 10.

A width of the groove 22 of second kink 20 is larger than a width of the groove 22 of the first kink 20 in a direction transverse to the longitudinal axis A.

In this connection it should be noted that a width of the groove 22 of the second kink 20 can be selected in the range of 1% to 5% of a length L of the applicator 10.

In this connection it should further be noted that the second kink 20 is arranged at a length corresponding to 10 to 30% of a length L of the applicator 10.

In this connection it should be further noted that a width of the groove 22 of the first kink 18 is selected in the range of 0.2 to 1% of a length of the applicator 10.

In this connection it should further be noted that the first kink 18 is arranged at a length corresponding to 2 to 10% of a length L of the applicator 10.

The material of the application tip 14 made of foam can be one of polyethylene (PE), polypropylene (PP), poly vinyl chloride (PVC), polyurethane (PU), polystyrene (PS) and combinations of the foregoing.

FIG. 6 shows a view of yet a further applicator head 12. The application tip 14 has four claws 44 that form a cage 46 in which a fluid can be collected on use of the applicator 10 of FIG. 6.

The claws 44 are connected at each end to one another and are curved in shape and merge into a tip 48 at a most distal point of the applicator 10.

FIG. 7 shows a view of yet a further applicator head 12. The application tip 14 is a brush 24 with bristles 26. In contrast to the brush 24 with bristles 26 shown in connection with FIGS. 1 to 4, the bristles 26 extend in parallel to one another and only in two directions that are oppositely disposed with respect to the longitudinal axis A rather than radially with respect to the longitudinal axis A.

A method of forming the applicator 10 can comprise the steps of injection molding the elongate body part 16 and then injection molding the applicator head 12 over and onto parts of the elongate body part 16.

On using the applicator 10 a user can decide where the applicator 10 is intended to be used and then bend the application tip 14 relative to the elongate body part 16 at least once at one of the first and second kinks 18, 20 prior to using the application tip 14 even at hard to reach target cites.

FIGS. 8A to 8C show a further type of the applicator 10. This applicator 10 comprises an undulating surface 46. Such an undulating surface 46 can be beneficially used by a user of the applicator 10 to grip the applicator 10 in an improved manner.

The undulating surface 46 covers approximately 20% of the outer surface of the elongate body part 16. In this connection it should be noted that it could be arranged to cover between 5 and 30%, preferably between 10 and 25%, of the outer surface of the elongate body part 16.

The undulating surface 46 comprises a plurality of peaks 52 and valleys 54. In the example shown 13 peaks 52 and 12 valleys are provided. In this connection it should be noted that a respective number of peaks 52 and valleys 54 selected in the range of 5 to 40 can be provided. It is generally desirable if the number of peaks 52 provided is one more than the number of valley 54, i.e. if six peaks are provided then 5 valleys 54 can be provided and if 40 peaks 52 are provided then 39 valleys 54 can be provided.

As can also be seen from FIG. 8A two first points of injection 48 and one second point of injection 50 are provided. The first points of injection 48 are disposed at the elongate body part 16 and the second point of injection 50 are disposed at the applicator head 12.

As can be seen from the enlarged view of FIG. 8B one of the first points of injection 48 is disposed at the undulating surface 46 and the second point of injection 50 is disposed at the kink 18 arranged at the applicator head 12.

In this connection it should be noted that the term point of injection refers to a formation at which the material of the respective component is injected into a mold for forming the applicator 10, with the formation remaining visible at the outer surface of the applicator 10 in the region of where the respective material was injected into the mold for the formation of the corresponding part of the applicator 10.

FIG. 8C shows a side view of the applicator of FIG. 8B indicating the position of the formations remaining after formation of the respective part, i.e. their points of injection 48, 50.

The respective point of injection 48, 50 is disposed in the vicinity of a filigree component to be formed as the material will flow best out of an injection nozzle (not shown) at this point as it has the highest temperature and pressure at the injection nozzle meaning that it will flow best into these filigree components from the injection nozzle.

It should also be noted that the grip shown in the manner of an undulating surface 46 in FIGS. 8a to 8c can also be formed at the other kinds of applicators 10 shown in the foregoing. Similarly, the other kinds of applicators can also have the first and second points of injection that are respectively present at regions of the applicator 10 where the material can be beneficially injected into a mold for forming the respective part at increased efficiency and with improved results.
