Description

The invention relates to a storage and application device for liquid, in particular nail polish.

Such storage and Appliziereinrichtungen have long been known.

In particular nail polish bottles, but also other storage and application devices are often constructed as follows: They have a body (often in the form of a glass vial), which encloses a storage space. Here, at least a part of the body is designed as a hollow neck with an external thread. The hollow neck ends at an end face. In the case of a body formed as a vial, the hollow neck may also be referred to as a bottleneck.

Furthermore, the storage and Appliziereinrichtungen a closure and Appliziereinheit. This consists of an internal thread having, screwed onto the external thread cap and an applicator connected to the cap applicator, at its free end an applicator, for example in the form of a brush, is formed. The brush consists of a hair body formed from a variety of hair. In order to fully maintain the functionality of the applicator (ie the brush), it is usually necessary that it does not touch the bottom of the storage space in any condition, otherwise it deforms would, which would diminish its utility value. The applicator takes the minimum distance from the bottom of the storage room only with screwed cap. In general, however, the cap should not be screwed during use (in the present case when painting the fingernails), which is also difficult, since this requires both hands. This results in the problem that the use of the nail polish bottle is quite difficult when their level is nearing the end and / or that a relatively large amount of nail polish remains and is thrown away.

To solve the problem described suggests the DE 297 02 226 U1 in that the applicator carrier extends through the closure cap so that its first end is outside the closure cap and is connected thereto by means of a spring. By pressure on the first end, the applicator carrier can thus be displaced in relation to the closure cap in such a way that the distance of the applicator from the closure cap is increased. Thus, you can immerse the applicator when placed on the hollow neck cap deeper into the receiving space.

Although the described storage and application device can thus basically partially solve the problem outlined above, it has numerous practical disadvantages. On the one hand, the one-handed operation is relatively difficult because at the same time the body (the vial) must be held and pressed onto the first end of the applicator carrier. Furthermore, the effort that one must operate to achieve the necessary tightness in the storage condition, very high. Finally, the production cost is high.

From the US 3,337,901 a storage and application unit for nail polish is known, in which on the applicator Aufschraubbegrenzungsmittel are formed to rest on the end face of the container neck. Between the cap and the applicator, an elastic element acts in the form of a compression spring, such that the cap is axially movable when the Aufschraubbegrenzungsmittel to the end faces Unte exciting the elastic element relative to the applicator from a use position into a screwed-on closure position. The cap is designed in several parts and has a cap-shaped conical outer part and also a cap-shaped conical inner part, which is pressed into the outer part. Between the applicator and the inner part of a stop and a counter-stop are formed, which jointly specify by mutual striking the screwed-on closure position.

The object of the invention is to provide a storage and application device for liquid of the type mentioned above, with which can solve the aforementioned problems and which is also easier and less expensive to manufacture compared to the prior art.

This object is achieved by a storage and Appliziereinrichtung with the features of the independent claim 1. Further developments of the invention are shown in subclaims.

The storage and applicator according to the invention for liquid, in particular nail varnish, has a container interior having reservoir for liquid, which has a container opening equipped with a container opening, which has an end face and one with a External thread equipped jacket surface, wherein a closure and Appliziereinheit is provided, which has an internal thread, screwed onto the external thread cap and an applicator with the cap coupled applicator with Aufschraubbegrenzungsmitteln for abutment with the end face, wherein the applicator on an end facing away from the cap an applicator for applying the liquid, and wherein an acting between the cap and the applicator applicator elastic element is present, such that the closure cap upon contact of the Aufschraubbegrenzungsmitteln to the end face under tensioning the elastic member relative to the applicator from a use position into a screwed-on closure position is guided axially movable by means of guide means, wherein the guide means formed on the applicator stop and a stopper formed on the cap Counter-stop, which together define by mutual striking a use position and the closure position, wherein the closure cap is formed in several parts, with a cap-shaped outer part and a coaxial in the externally fixed sleeve-shaped inner part, on the inner shell of the counter-stop is formed.

In contrast to the aforementioned prior art in the form of US 3,337,901 the inner part is formed as a sleeve, so it is a component open on both sides, resulting in great advantages in the production. In general, the caps are made of plastic, in particular these are plastic injection molded components. In plastic injection molding, the cost of the tool (injection mold) plays a major role. The simpler the shape is built, the easier is the demolding of the molded plastic component and the cheaper the plastic injection molded parts are to produce. In the aforementioned prior art, the inner part is cap-shaped and has a trained as a stop shoulder on the inner shell. The demolding of such a cap-shaped component with internal shoulder is relatively complicated and therefore expensive. In the storage and application device according to the invention, however, the demolding can be done much more cost-effective, since the inner part is designed as a sleeve, whereby in particular the counter-stop, which cooperates with the stop on the applicator, much easier to demold and thus produce is two shapes can be used, which can then be extended by the oppositely disposed openings of the sleeve with ready-molded plastic sleeve.

In a particularly preferred manner, the inner part has an inner jacket and a cylindrical outer jacket.

In a further development of the invention, the stop has a first and a second stop surface and the counter-stop on a first and second counter stop surface, wherein for specifying the use position first stop and first counter-stop and to specify the closing position second stop and second counter Stop in the system to each other.

Thus, both the screwed-on closure position and the use position are predetermined by stop and counter-stop.

Particularly preferably, the first and second stop surfaces facing each other and spaced apart in the axial direction.

Conveniently, the first and second mating abutment surfaces are remote from each other.

In a further development of the invention, the abutment surfaces of end faces of an annular groove are formed.

It is possible that the counter-abutment surfaces are formed by end faces of a protrusion dipping into the annular groove. Appropriately, the projection is designed as an annular stop collar.

The annular groove has over the dipping projection a significantly larger axial extent.

In a particularly preferred manner, the stop is formed on the applicator carrier. Accordingly, it is preferred that the counter-stop is formed on the inner part of the closure cap. In principle, however, it would also be possible to form the counter-stop on the applicator carrier and the stop on the inner part of the closure cap. It is advantageous, however, that the stop in the form of an annular groove on the applicator carrier and the counter-stop in the form of a projection, in particular annular stop collar on the closure cap is formed.

In a further development of the invention fixing means are provided for fixing the inner part in the outer part, which are designed such that the outer and inner parts are rotationally fixed and fixed relative to each other relatively immovable in the axial direction. Expediently, the fixing means comprise interlocking means on the one hand the outer part and on the other hand on the inner part, which engage radially in one another and thereby provide an axial securing of the inner part in the outer part.

In one embodiment of the invention, the inner part of the internal thread. The internal thread is expediently formed on the inner jacket of the inner part.

In a further development of the invention, the elastic element acts on the closure cap away from the applicator carrier and biases it into the use position when the threads do not mesh with one another.

In a particularly preferred manner, the elastic element is designed as a spring, in particular compression spring.

Conveniently, the compression spring is supported on the one hand on the applicator carrier and on the other hand on the outer part of the closure cap, in particular on a roof section of the closure cap.

In one development of the invention, the applicator carrier has a shank portion, at the free end of which the applicator is arranged and has a diameter portion which is larger than the shank portion, wherein the screw-on limit means are formed by an annular shoulder at the transition between the bearing portion and the shank portion.

In a further development of the invention, anti-rotation means for preventing rotation between the closure cap and the applicator carrier are present between the bearing section of the applicator carrier and the inner part of the closure cap.

In a particularly preferred manner, the anti-rotation means by a polygonal profile the bearing portion on the one hand and the inner shell of the inner part on the other hand formed.

The FIGS. 1 to 3 show a preferred embodiment of the storage and applicator 11 according to the invention, which serves according to the embodiment for storage and application of nail polish.

The storage and applicator 11 has a container interior 12 having reservoir 13 for the nail polish. In the exemplary embodiment shown, the storage container 13 has a belly section 14 which surrounds the container interior 12, wherein a belly section 14 is not absolutely necessary. It is essential that the reservoir 13 has a container neck 15, the one of Channel-like container opening 16 is interspersed. The interior of the container neck 15, so the channel-like container opening 16 is not filled, but the highest level is usually just below the container neck 15. The container opening 16 is used in this case only for access to the container interior 12. The container neck 15 has a lateral surface 17, on which an external thread 18 is formed. Further, the container neck 15 has an annular end face 19th

How the particular FIGS. 1 and 2 1, the storage and application device 11 has a closure and application unit 20, which consists of two main components, a closure cap 21, which will be explained in more detail below, and an applicator carrier 22 with associated applicator 23. The applicator carrier 22 consists in the example described made of plastic. In particular, the applicator carrier 22 is a one-piece plastic injection molded component.

The applicator carrier 22 has a shaft section 24 that is round, in particular circular, relatively elongate and extends along a longitudinal axis of the applicator carrier 22, which is flexible. Optionally, profilings (not shown) may be formed on the outer circumference or on the lateral surface 17 of the shank portion 24, whereby the lacquer flow from the shank in the direction of the applicator 23 is improved.

The shaft portion 24 is integrally connected in the example described with a bearing portion 26 which connects coaxially with the shaft portion 24 to this. The bearing portion 26 has over the shaft portion 24 has a larger diameter. Thus, at the transition between the shank portion 24 and the larger diameter bearing portion 26 an annular shoulder 27 is formed, the Aufschraubbegrenzungsmittel 28 forms, if the annular shoulder 27 is attached to the end face 19 of the container neck 15.

As in particular in FIG. 1 shown, may be formed on the annular shoulder 27, an annular seal in the form of a sealing collar 29. The sealing collar 29 seals the passage between the annular shoulder 27 and the end face 19 of the container neck 15.

The bearing portion 26 of the applicator 22 has a relatively elongated, coaxially aligned with the longitudinal axis 25 receptacle 30, which is formed in the example as a cylindrical receiving opening in the form of a blind hole. In the cylindrical receiving opening, an elastic element in the form of a compression spring 31 is inserted, which is supported on the one hand on a bottom 32 of the cylindrical receiving opening and on the other hand on the closure cap 21. The compression spring 31 thus acts between the applicator carrier 22 and the closure cap 21. The function will be explained in more detail below.

The bearing section 26 has an outer jacket on which there are a plurality of, for example, two or three pocket-shaped recesses 34 grouped around the longitudinal axis in regular sections.

At the in FIG. 3 shown variant, instead of the pocket-shaped recesses 34, an annular groove 35 is formed, which has an axial extent, wherein the bottom of the annular groove 35 is formed by sections of a polygonal profile, for example hexagonal profile.

The shank portion 24 of the applicator carrier 22 has a bearing end 26 opposite free end 36 to which an applicator 23 is arranged in the form of a brush.

At the free end 36 of the shank portion 24 is formed in the axial direction to the longitudinal axis 25 aligned receiving recess (not shown). In this receiving recess a hair body 38 consisting of a plurality of hairs 37 is received. The receiving recess may for example be formed as a punched hole. The attachment of the hair body 38 in the receiving recess is expediently carried out with the aid of a wire clamp which, on the one hand, claws into the material of the shaft portion 24 and, on the other hand, holds the hair 37 together in the hair body 38.

As mentioned above, acts between the cap 21 and the applicator 22, an elastic element in the form of a compression spring 31. When the Aufschraubbegrenzungsmitteln, so the annular shoulder 37 to the end face 19, the closure cap 21 is under tensioning of the compression spring relative to the applicator 22 of a use position 39 in a screwed-on closure position 40 guided by means of guide means 41 axially movable.

The guide means 41 comprise a stop 42 formed on the applicator carrier 22 and a counter-stop 43 formed on the closure cap 21, which together define the use position 39 and the closure position 40 by striking against each other.

An important aspect of the invention is the design and arrangement of the counter-stop 43. As in particular in the FIGS. 1 and 2 shown, the cap 21 is a multi-part formed, with a cap-shaped outer part 44 and a coaxially fixed in the outer part 44 sleeve-shaped inner part 45, on the inner shell 46 of the counter-stop 43 is formed. The closure cap 21 is expediently made of plastic, ie the outer part 44 as well as the inner part 45 are made of plastic, in particular outer part 44 and inner part 45 are plastic injection molded components.

The outer part 44 has a base portion 47 which is as exemplified in FIG FIG. 1 shown in the screwed-on closure position 40, the bearing portion 26 of the applicator 22 and the container neck 15 completely encloses. The base portion 47 of the closure cap 21 has an outer shell 48 with a cylindrical, in particular circular cylindrical cross-section. Further, the base portion 47 has an inner shell 49 facing the inner part 45. Expediently, the inner shell of the outer part 44 has a cylindrical, in particular circular cylindrical cross section. The outer part 44 has in addition to the base portion 47 in a transverse to the longitudinal axis 45 extending and integrally attached to the base portion 47 roof portion 50, the inner surface 51 serves as a bearing surface for the compression spring 31.

As exemplified in FIG. 1 shown, the inner part 45 is completely received in the outer part 44 and fixed there by means of fixing 52 such that the outer part 44 and inner part 45 are rotationally fixed relative to each other and relatively immovable fixed in the axial direction.

In the example shown, the fixing means 52 are formed by positive locking means. In the example case, recesses 43 arranged around the longitudinal axis in the circumferential direction and projections 44 dipping into the recesses 43 are provided as positive locking means. In the example shown are the recesses are formed on the outer casing 55 of the inner part 45, while the projections 54 are arranged on the inner casing 49 of the outer part 44.

As in particular in the FIGS. 1 and 2 shown, the stop 42 and the counter-stop 43 together by mutual striking both the use position 39 and the closure position 40 before. The stop 42 has a first and a second stop surface 56a, 56b, while the counter-stop 43 has a first and second counter-abutment surface 57a, 57b. To specify the use position 39, the first abutment surface 56a and the first abutment surface 57a are in contact with each other. To specify the screwed-on closure position 40, the second abutment surface 56b and the second abutment abutment surface 57b bear against each other.

In the example shown, the stop 52 is formed on the applicator carrier 22 and the counter-stop 53 on the closure cap 21.

As already mentioned above, is located on the bearing portion 46 has a circumferential annular groove 35 which is bounded in the axial direction of end faces, of which the upper end surface of the first abutment surface 56a and the second lower end surface facing the second abutment surface 56b forms.

The counter-stop 53 is accordingly arranged on the inner part 45 of the closure cap 21. The counter-stop 53 is formed in the form of a dipping into the annular groove 35 projection 58. There may be a plurality of circumferentially on the inner shell 46 of the inner part 45 radially inwardly projecting projections 58 may be formed or alternatively, it is possible that the projection 58 is formed as an annular stop collar.

As in particular in the FIGS. 1 and 2 shown, the counter-abutment surfaces 57 a, 57 b are formed from opposite end faces of the projection 58.

As in particular in the FIGS. 1 and 2 shown, the inner part 45 has next to the counter-stop 53 in the form of the projection 58 on the inner shell 46 also formed on the inner shell 46 internal thread 59, which cooperates with the container neck 15 formed on the external thread 18 when screwed.

The inner part 45 is a sleeve that is open at both ends. Such a sleeve is relatively easy to produce by means of plastic injection molding, since it can be demolded from both sides and the annular stop collar or projection 58 can be formed on the separation of the two moldings. As a result, the radial extent of the projection 58 on the inner casing 46 of the inner part 45 can be relatively large, since there is no Entformungsproblem, which in turn relatively wide counter-stop surfaces 57a, 57b creates, creating a defined concern to the associated abutment surfaces 56a, 56b on the applicator 22 can take place.

Before use, the cap 21 is in the in FIG. 1 shown screwed closure position 40. In this closure position 40, the compression spring 31 is compressed, so claimed to pressure. The closure position 40 is by mutual concern of the lower counter-stop surface 57b on the inner shell 46 of the inner part 45 of Closure cap 21 on the lower stop surface 56b on the bearing portion 26 of the applicator 22 predetermined.

To the cap 21 in its use position 39 according to FIG. 2 to bring this is unscrewed, whereby the two threads 18, 59 are disengaged. As soon as this occurs, the previously tensioned compression spring 31 provides its spring energy and presses the closure cap 21 away from the applicator carrier 22, namely until the upper counterstop surface 57a abuts against the upper stop surface 56a. The immersion depth of the shaft portion 24 in the reservoir 13 is always the same, regardless of the position of the cap 21, ie in the use position 39 is given by the abutment of the Aufschraubbegrenzungsmittel 28 to the end face 19, the immersion depth, the screw when screwing the cap 21 by the relative Mobility between the cap 21 and the applicator 22 is not changed.
