EP3169598B1 - Dosing cap comprising a brush device - Google Patents

Description

The invention is based on a dosing cap for a cleaning agent container, having a cup-shaped cap body with an open end part and a closed end part and a brush device for pre-treating objects to be cleaned.

Such dosing caps are well known. For example, from the publication WO 2014/004456 A1 a dosing cap is known in which surface irregularities are arranged on the outer base surface of the dosing cap. However, it is disadvantageous with this dosing cap that the dosing cap has to be turned over after the detergent dose has been applied to the laundry to be cleaned so that the detergent with the surface irregularities can be distributed and rubbed into the laundry. This makes using this conventional dosing cap comparatively cumbersome.

It is therefore the object of the present invention to provide a dosing cap that does not have the disadvantages of the prior art and in particular enables comfortable and user-friendly pretreatment.

Disclosure of the invention

This object is achieved with the dosing cap according to the invention according to claim 1. Because the brush attachment can be repositioned, it is advantageously possible to plug the brush attachment either onto the closed end part or onto the open end part, depending on your needs or intended use. If the brush attachment is to be visible on the cleaning agent container for presentation purposes, for example on a store shelf, the brush attachment is placed on the closed end part. If the brush attachment is used to pre-treat objects, such as

Laundry to be used, the brush attachment is placed on the open end part. Therefore, with the dosing cap according to the invention it is advantageously possible to combine the advantages of both positions of the brush attachment with one another. On the one hand, the brush attachment can be placed on the closed end part in an advertising-effective way that is visible to the consumer. On the other hand, the handling of the dosing cap during pretreatment can be made much more comfortable if the brush attachment is placed on the open end part, because after applying a cleaning agent, such as liquid detergent, the dosing cap can be distributed and rubbed in directly onto the object without turning it over cleaning agent with the brush attachment.

The brush attachment extends along a longitudinal direction, a width direction perpendicular to the longitudinal direction and a transverse direction perpendicular to the longitudinal direction and the width direction. If in the following we talk about “above” or “upper” and “below” or “lower”. is meant position information with reference to the longitudinal direction. When we talk about cross-section or cross-sectional area or cross-sectional plane below, we mean cuts parallel to the plane that is spanned by the width direction and the transverse direction or that is arranged perpendicular to the longitudinal direction.

According to the invention it is provided that the brush attachment has an annular brush attachment body designed in such a way that the lower part of the brush attachment body can be plugged onto the cap body and a large number of bristles are arranged on its upper part. With this annular design, a particularly efficient implementation of the brush attachment is advantageously possible. The brush attachment body is essentially rotationally symmetrical to its longitudinal axis, which extends parallel to the longitudinal direction. The cross-sectional plane of the brush attachment body lies perpendicular to the longitudinal axis of the brush attachment body, thus parallel to the plane spanned by the width direction and the transverse direction.

Furthermore, it is provided that the brush attachment body has a larger cross section on its lower part than the cross section of the cap body in the area of the closed or open end part, so that the brush attachment can be inserted over the outer surface of the corresponding end part. The brush attachment body can be designed in such a way that pushing the brush attachment body onto the cap body results in a sufficiently strong connection between the brush attachment body and the cap body, so that the brush attachment remains firmly arranged on the cap body, for example when the object is pre-treated.

For example, it can be provided in particular that the brush attachment is designed to be reversible in such a way that the brush attachment is in a first position when it is plugged onto the closed end part, or is in a second position when it is plugged into the open end part, wherein the brush attachment can be variably repositioned between the first position and the second position. This advantageously enables particularly comfortable use of the dosing cap.

The dosing cap is designed in such a way that it can be used to fill a partial dose of the cleaning agent contained in the cleaning agent container. For this purpose, the dosing cap can, for example, have marking lines and volume information that indicate the corresponding filling quantity. In addition, the dosing cap is designed such that it can close an outlet of the cleaning agent container. In addition, the dosing cap is designed such that it can be connected to the cleaning agent container, for example via a screw connection. The cleaning agent container can be any type of vessel into which a cleaning agent can be placed. The cleaning agent can have any type of composition that allows objects to be cleaned. It can be at The cleaning agent can be, for example, detergents, in particular liquid detergents, and/or dishwashing detergents, etc. The items to be cleaned can be, for example, laundry and/or dishes, etc.

The cup-shaped cap body can have any shape that allows cleaning agent to be poured into the cap body and the cleaning agent to be applied to the object to be cleaned. At the closed end part, the cap body has a closed shape so that the cleaning agent cannot flow out of the dosing cap. At the open end part, the dosing cap has an opening which enables the cleaning agent to be poured out of the dosing cap onto the object. The brush device or the brush attachment is designed in such a way that it enables the object to be pretreated. The brush attachment can be designed in such a way that it enables, for example, the cleaning agent to be distributed on the object and/or the cleaning agent to be rubbed into the object.

Advantageous refinements and further developments of the invention can be found in the subclaims and the description with reference to the drawings.

According to an exemplary development, it is provided that the brush attachment has a large number of bristles with a length of 4 mm to 20 mm. In this length range, a comparatively good pretreatment effect is advantageously achieved. According to a preferred development, it is provided that the bristles have a length of 6 mm to 10 mm, whereby a very efficient pretreatment can advantageously be achieved. In addition, with this length, a particularly good visibility of the bristles for the consumer can be achieved when the brush attachment is in the first position on the closed end part and the dosing cap is on the cleaning agent container, which is placed on a store shelf, for example. The large number of bristles can have different lengths, but it can in particular be provided that all bristles have the same length. The bristles can in particular be circular cylindrical, preferably slightly conical.

According to another exemplary development, it is provided that the bristles have a diameter of 0.3 mm to 3.0 mm. In this diameter range, a comparatively good pretreatment effect is advantageously achieved. According to a preferred development, it is provided that the bristles have a diameter of 0.8 mm to 1.0 mm. This means that a very efficient pretreatment can advantageously be achieved. The large number of bristles can have different diameters, but it can in particular be provided that all bristles have the same diameter.

According to another exemplary embodiment, it is provided that the bristles have a hardness in the range from 30 to 110 Shore A. This advantageously makes it possible to achieve a comparatively high level of flexibility, which means that particularly good pretreatment is possible. According to a preferred development, it is provided that the bristles have a hardness of 50 to 70 Shore A. Optimal pretreatment is possible in this area. The large number of bristles can have different degrees of hardness, but it can in particular be provided that all bristles have the same degree of hardness.

In particular, it can be provided that the brush attachment is made of an injection-molded material. In particular, the brush attachment is made of a rubber material and/or a plastic material. The lower part of the brush attachment body is plugged onto either the open end part or the closed end part. The upper part opposite the lower part accordingly has the large number of bristles.

An outside diameter at the closed end portion of the cap body may differ from an outside diameter at the open end portion of the cap body. Preferably the outside diameter at the closed end part is smaller than the outside diameter at the open end part. A lateral surface of the cap body can be conical at least in the area of the closed end part, so that during its production the cap body with its closed end part can be thrown out of an injection mold half. The difference in the outside diameters can be at least 2 percent based on the larger outside diameter.

The brush attachment or the cap body can have connecting means, so that a brush attachment attached to the closed end part and a brush attachment attached to the open end part can only be removed by overcoming a lifting force, even if, as in the exemplary embodiment explained above, the outer diameter is closed and open end part are different. The lifting force (in the axial direction of the cap body perpendicular to the cap base) should be greater than 2 N. Preferably, the lifting force for the closed end and the open end is each greater than 20 or even 100 N.

In one embodiment, the connecting means include elastic restoring forces of the brush attachment body. If the brush attachment is placed on the open end part or the closed end part of the cap body, the brush attachment body expands accordingly. The resulting elastic restoring forces ensure a firm hold of the brush attachment on the cap body. With appropriate material selection (e.g. silicone, elastomeric material), a tight fit on both end parts of the cap body can be made possible, even if the outer diameters at the closed end and at the open end differ from one another.

The connecting means may include adhesive. Alternatively or in addition to the elasticity of the brush attachment body, appropriate adhesive can be applied between the brush attachment and the cap body. One possibility here is to apply the adhesive to the outer wall of the cap body and, as long as the adhesive is still liquid or not yet hardened, to slide the brush attachment onto the closed end of the cap body. Adhesive strips can also be used, which are arranged between the brush attachment and the cap body.

According to another exemplary embodiment, it is provided that the brush attachment has a web on which the plurality of bristles are arranged, the web being arranged in the upper region of the brush attachment body or on its upper part. The jetty is plate-shaped and connected to the large number of bristles. In particular, the bristles can be arranged perpendicular to the surface of the web. The bristles can be evenly spaced apart and in particular arranged in a line shape, with several lines being able to be arranged one behind the other and/or offset from one another. For example, the bristles may be evenly spaced from one another at a distance of 1 mm to 2 mm.

It can be provided that the web is arranged parallel to the cross-sectional area or to the cross-sectional plane of the brush attachment body. The web or its surface is therefore also arranged perpendicular to the longitudinal axis of the brush attachment body. According to an exemplary embodiment, the web is approximately semicircular and covers approximately 40% to 50% of the cross-sectional area of the brush attachment body, so that an approximately semicircular upper opening is formed. This upper opening is formed between an upper edge of the brush attachment body, which limits the brush attachment body upwards, and an edge of the web, this upper opening allowing the metered cleaning agent located in the dosing cap to exit the dosing cap on the web can be applied with the bristles onto the object to be cleaned. This advantageously enables particularly comfortable handling of the dosing cap.

In particular, it can be provided that the large number of bristles are surrounded by a circumferential collar which is arranged on the web. This collar advantageously prevents the cleaning agent from accidentally flowing off the bridge or the bristles. In particular, it can be provided that the collar has a height of 2 mm to 10 mm. The collar extends perpendicular to the surface of the web and the height of the collar is the vertical extent of the collar in relation to the surface of the web. According to a preferred embodiment, the collar height is 3.0 mm to 4.0 mm.

According to an exemplary embodiment of the present invention, it is provided that the brush attachment has a corrugation arranged laterally on the outer wall of the brush attachment body, the corrugation having indentations with a depth of 0.1 mm to 0.3 mm. The ribbing allows the user to grip the brush attachment better during pre-treatment. The corrugation with the indentations also enables the cleaning agent to be finely distributed on the object and thus improves the pre-treatment options of the brush attachment or the dosing cap. In particular, it can be provided that the indentations and projections on the outer wall of the brush attachment body alternate regularly, so that a particularly efficient gripping or pre-treatment surface is created. For example, the distance between adjacent indentations can be approximately 1 mm.

In particular, it can be provided that the corrugation comprises at least one corrugated area which extends in an angular range of 40° to 60° on the outside or outer wall of the brush attachment body. This angular range refers to a circular arc segment which is arranged on the outer wall of the annular brush attachment body. With this For example, the corrugated angular area allows efficient distribution of the cleaning agent. In particular, the corrugation on the outer wall of the brush attachment body can comprise two spaced apart corrugated areas which lie opposite one another with respect to the longitudinal axis of the brush attachment body. With this arrangement of the corrugated areas, a particularly efficient pretreatment is possible.

A further subject of the present invention relates to a cleaning agent container, having a dosing cap according to one of the preceding embodiments, wherein the brush attachment is either in a presentation state of the cleaning agent container on the closed end part of the dosing cap or is in a use state of the cleaning agent container on the open end part of the dosing cap. The presentation state can, for example, be the state in which the container is located if the brush attachment is to be particularly clearly visible to the consumer on a store shelf. The state of use is the state in which the container is when the brush attachment or the dosing cap is to be used for pre-treatment. It can be provided that, when in use, the brush attachment is arranged inside the container and is therefore not visible from the outside. Furthermore, please refer to the information on the dosing cap.

Another subject of the present invention relates to a use of a dosing cap according to one of the preceding embodiments for the pretreatment of laundry to be cleaned, wherein a partial amount of a detergent from a liquid detergent container is filled into the dosing cap, the partial amount being applied from the dosing cap to the laundry to be cleaned , whereby the applied detergent is distributed over the laundry to be cleaned using the brush attachment placed on the open end part of the cap body and rubbed into the laundry to be cleaned. It is advantageously possible to attach the brush attachment to the open end part for pre-treatment of the laundry, so that the dosing cap does not have to be turned over after the detergent has been applied. Please refer to the information on the dosing cap and the cleaning agent container.

Embodiment(s) of the invention

In the various figures, the same parts are always provided with the same reference numbers and are therefore usually only named or mentioned once.

Figure 1 shows schematically a dosing cap 1 according to an exemplary embodiment of the present invention. The dosing cap 1 has a cup-shaped cap body 3. In this embodiment, the cap body 3 is designed as a hollow circular cylinder. The cap body 3 has an open end part 4 and a closed end part 5. A brush attachment 2 is attached to the closed end part 5. The brush attachment 2 extends along a longitudinal direction X, a width direction Y perpendicular to the longitudinal direction When “lower” is mentioned, position information is meant with reference to the longitudinal direction X. When we talk about cross-section or cross-sectional area or cross-sectional plane YZ in the following, we mean cuts parallel to the plane that is spanned by the width direction Y and the transverse direction Z. The brush attachment 2 is circular and has a larger cross section than the closed end part 5, so that the brush attachment 2 can be inserted over the outer surface of the closed end part 5. In this embodiment, the brush attachment 2 has a large number of bristles 6, which are arranged perpendicular to the surface of the brush attachment 2. The bristles 6 are surrounded by a collar 7, which is arranged perpendicular to the surface of the brush attachment 2 and runs around the bristles 6. The brush attachment 2 is located on the closed end part 5 in a first position. This first position could, for example, be the position in which the dosing cap 1 is arranged on a liquid detergent container 20 when this is placed on the store shelf for advertising or presentation purposes. For reasons of clarity, for example, connecting means for connecting the dosing cap 1 to the liquid detergent container 20, such as a screw thread, are not shown.

Figure 2 shows schematically the dosing cap 1 Figure 1 in a different state. In this state, the brush attachment 2 is in a second position on the open end part 4. For this purpose, the brush attachment 2 has a larger diameter in cross section than the diameter of the open end part 4, so that the brush attachment 2 can be plugged onto the open end part 4. This second position could, for example, be the position in which the dosing cap 1 is used to pre-treat laundry. Detergent is applied to the laundry from the dosing cap 1 applied and then distributed on the laundry with the brush attachment 2 and rubbed into the laundry.

Figure 3 shows schematically a brush attachment 2 for a dosing cap 1 according to another exemplary embodiment of the present invention in a perspective view. The brush attachment 2 has a brush attachment body 9. The brush attachment body 9 is designed in the shape of a circular ring and, in this exemplary embodiment, has a cross-section in the shape of a circular ring. The brush attachment body 9 is essentially rotationally symmetrical to its longitudinal axis X, which extends parallel to the longitudinal direction X. The cross-sectional plane YZ of the brush attachment body 9 lies perpendicular to the longitudinal axis X of the brush attachment body 9, thus parallel to the plane spanned by the width direction Y and the transverse direction Z. The brush attachment 2 has an upper opening 11 and a lower opening 12. In this exemplary embodiment, approximately half the cross section of the upper opening 11 is covered by a web 8 on which a large number of bristles 6 are located. In this embodiment, the bristles 6 are evenly spaced apart and extend approximately perpendicular to the cross-sectional area YZ of the upper opening 11. The distance between adjacent bristles 6 is approximately 1 mm to 2 mm. The web 8 is designed as a flat plate and extends parallel to the cross-sectional area YZ of the upper opening 11. In this exemplary embodiment, the bristles 6 have a length of approximately 10 mm and a diameter of approximately 0.9 mm, the bristles 6 being circular cylindrical are trained. The bristles 6 are designed to be flexible and have a hardness of approximately 70 Shore A. The web 8 is bordered on its edge by a collar 7. The collar 7 is formed all around the edge of the web 8 and extends perpendicular to the cross-sectional area YZ of the opening 11 or to the surface of the web 8. In this exemplary embodiment, the collar 7 has a height of approximately 3.5 mm. The web 7 advantageously serves, among other things, to prevent the detergent from flowing down the side of the brush attachment 2.

On the outer wall (hereinafter also referred to as the outer wall) of the brush attachment body 9, a corrugation 10 is arranged, which in this exemplary embodiment has a depth of approximately 0.2 mm. The corrugated area 10 extends on the outer wall of the brush attachment body 9 over an angle of approximately 50°. In this exemplary embodiment, the brush attachment 2 also has a second corrugated area 110, which, however, is in the Figure 3 is not visible. This second corrugated region 110 is located opposite the corrugated region 10 on the other side of the outer wall of the brush attachment 2. In this exemplary embodiment, this second corrugated region 110 is designed identically to the corrugated region 10.

This brush attachment 2 can now be used to pre-treat laundry. If the brush attachment 2 is attached to the open end part of the cap body 3, detergent can be applied to the laundry from the dosing cap 1 through the remaining opening 11, which is not covered by the web 8. The bristles 6 can be used to distribute the detergent on the laundry and rub it into the laundry. With the side corrugations 10, 110 you can also do one Pretreatment takes place by rubbing the detergent with the corrugations 10, 110, which makes a particularly fine treatment of the laundry possible. Alternatively, it is of course also possible to use the brush attachment 2 separately, i.e. without the cap body 3, for pretreatment.

Figure 4 shows schematically a side view of the brush attachment 2 Figure 3 . You can see in the Figure 4 Among other things, the uniform contact of the bristles 6. It can also be seen that the collar 7 covers the lower area of the bristles 6. In this exemplary embodiment, the web 8 has a thickness of approximately 1 mm to 2 mm. For the rest, please refer to the comments on Figure 3 referred.

Figure 5 shows schematically the brush attachment 2 from the Figure 3 in a top view from above. The cross section of the brush attachment body 9 is symmetrical to the lines of symmetry 13, 14. In this view it can be seen that the web 8 covers approximately half of the cross section of the brush attachment body 9. The inner part of the web 15 is curved approximately 2 to 4 mm outwards, ie away from the line of symmetry 13, in relation to the axis of symmetry 13 of the brush attachment body 9, so that the web 8 is slightly less than half, approximately 45%, of the Cross-sectional area of the brush attachment body 9 is covered. In addition, there are Figure 5 the two opposite ribbed areas 10 and 110 are indicated on the outer wall of the brush attachment body 9.

Figure 6 shows schematically a detailed view of the brush attachment 2 in the area of the web 8 with the bristles 6 in a sectional view along the plane that is spanned by the longitudinal axis X and the width direction Y. The two bristles 6 shown in dashed lines lie in a common plane, while the two bristles 6 not shown in dashed lines lie one plane behind them. Between two adjacent bristles 6 lying in one plane, a bristle is thus arranged, which lies one plane behind it. This results in a uniform distribution of the bristles 6 on the web 8. Furthermore, the comments on the Figures 3, 4 and 5 referred.

Figure 7 shows schematically the corrugation 10 on the outer wall of the brush attachment body 9 Figure 3 in a detailed view in a cross section. The corrugation 10 has regularly spaced indentations 16 and projections 17 which are distributed in the corrugated area 10 over the outer wall of the brush attachment body 9. The indentations 16 are approximately 0.2 mm deep in this exemplary embodiment. With this corrugation 10, a fine pre-treatment of the laundry can advantageously be carried out. Furthermore, please refer to the comments on the Figures 3, 4 , 5 and 6 referred.

Figure 8 schematically shows a detergent container 20, such as a liquid detergent container 20, according to an exemplary embodiment of the present invention. The cleaning agent container 20 has a dosing cap 1 according to the invention with a brush attachment 2. The brush attachment 2 is located on the closed end part 5 of the dosing cap 1. In this position, the brush attachment 2 is good for a consumer, for example visible when the cleaning agent container 20 is in a presentation state and is for sale or presentation on a store shelf.

Figure 9 shows schematically the cleaning agent container 20 Figure 8 in a different state. In this so-called state of use, the brush attachment 2 is no longer on the closed end part of the dosing cap 1 but the brush attachment 2 has been moved from the closed end part to the open end part 4 of the dosing cap 1. The brush attachment 2 is therefore located inside the cleaning agent container 20 and is no longer visible from the outside. In this state of use, cleaning agent can be filled from the container 20 into the dosing cap 1 and applied from the dosing cap 1 to, for example, the laundry. In a simple manner, the detergent can now be distributed on the laundry using the brush attachment 2 and rubbed into the laundry without the dosing cap 1 having to be turned over because the brush attachment 2 is located on the open end part 4 of the dosing cap 1. Furthermore, reference is made to the above statements

For the sake of completeness, it should be noted that the exemplary embodiments described above merely serve to illustrate the invention and are in no way intended to limit the subject matter of the invention.
