Description

Referring to Fig. 3, which shows the most commonly used type of applicator, this type of applicator a, e.g. lipstick or lip balm, is based on the principle of extending the carrier b of the mass c in the applicator and from the retracted position (Fig. 3a) to the extended position (Fig. 3a). Fig. 3b).

The carrier 6 is usually formed by a simple "cup", i.e. a hollow cylinder, one base of which is closed and the other open, which usually contains two cylindrical projections b1 on its outer shell. A considerable amount of mass c is placed in the "cup". It is usually about one third of the mass of the preparation, but it can be even more, see Fig. 3. Inside, the "cup" can contain elements to help mass c stored in the "cup" did not loosen and did not fall out.

The applicator a comprises an actuator a1 with a base a2 and an inner tube a3, which is usually an integral part of the base, and a cylindrical housing (not shown), the actuator a1 being adapted for pivotal connection with the housing and the housing and adapted to fit on the inner tube q3. of the control element a1 and for a pivotal connection with the control element a1.

The inner tube a3 usually comprises two slides a4 for guiding the two cylindrical projections b1. Both links a4 have a first transverse groove a41 at the first end of the link remote from the base a2 of the control element a1 for locking, i.e. securing the carrier b in the extended position and a second transverse groove a42 at the second end of the link closer to to base a2. which is oriented in the opposite direction to the first transverse groove a41 for locking the carrier b in the retracted position.

The housing usually comprises two helical cutouts (not shown) which are arranged on the inner wall of the housing for guiding the cylindrical projections b of the carrier b.

The cylindrical projections b1 of the carrier b are in contact with the links a4 i with the helical cutouts, and when the control element a1 and the housing are rotated relative to each other, the cylindrical projections b1, and with them the carrier b, are guided by the slides and helical cutouts from the retracted position to the extended position.

However, after consuming the mass that protrudes above the edge of the cup and / or the housing, a problem arises with the arrangement described above. The additional mass that is stored in the "cup" can no longer be consumed, because the type of carrier described above and the ejection mechanism no longer allow further ejection of the mass from the cup. Thus, in applicators that contain this type of carrier and the ejection mechanism, approximately one third of the material, often very expensive material, is not used at all.

U.S. Pat. No. 8,915,664 B2 discloses a lipstick wherein the mass is contained in a cup which is formed by an outer wall with a first guide cylindrical protrusion and a longitudinal cutout and a base located inside the outer wall and comprising a second guide cylindrical protrusion which fits into the longitudinal cutout of the outer wall for movement through the longitudinal cutout. The first and second guide cylindrical projections are located just above one another.

The outer casing of the lipstick is divided into a lower and an upper part. The lower part comprises a lower helical cut-out, the width of which is adjusted so that the first and second guide cylindrical projections with this cut-out

-1 CZ 2020 - 293 A3 move together. The upper part comprises an upper helical cut-out, which is adapted so that only one, namely the other, cylindrical guide protrusion can move through it. Thus, between the lower and upper part of the package, the vertical movement of the cup as a whole is stopped and by further rotation only the base moves vertically, guided by a second guide cylindrical protrusion, which is guided by the upper helical cutout and the longitudinal cutout in the outer wall of the cup.

Although the solution according to U.S. Pat. No. 8,915,664 B2 describes a two-phase mass ejection, it has a number of disadvantages.

The disadvantage is the material which, when inserted into the cup, fills the longitudinal cut-out in the outer wall, which makes it impossible or at least considerably impairs the functioning of the mechanism.

Furthermore, the solution does not allow the use of two opposite guide cylindrical projections (or more projections), because two different helices and actuation of two guide projections one above the other would lead to crossing at some point, which would prevent or at least significantly impair the operation of the mechanism. This has, among other things, a negative effect on the strength of the mechanism and the smoothness of the control, which in turn affects the failure rate of the mechanism.

Said solution also has other disadvantages, for example an unstable storage of the mass in the cup, because when the mass is inserted into the cup, air remains in the lower part, which has no way to escape.

The essence of the invention

The problem of unused mass remaining below the edge of the cup, resp. The applicator carrier solves the present invention and at the same time eliminates other above-mentioned disadvantages of the known solutions.

The subject of the invention is a mass carrier. The substance can be, for example, a cosmetic or a medicinal product. The mass carrier comprises a pull-out element having a substantially cylindrical shape with a first base, a second base and a housing and at least one cylindrical projection arranged on the surface of the housing. The carrier further comprises a hollow sleeve arranged around the circumference of the housing of the pull-out element having at least a first part at the first edge and a second part at the second edge, and mass securing means arranged on the first base of the pull-out element and / or at least part of the inner wall of the first part of the sleeve. The sleeve comprises at least one cutout adapted to contact the at least one cylindrical protrusion for connecting the pull-out element to the sleeve. The at least one cutout comprises means for locking the at least one cylindrical protrusion in the first locking position and in the second locking position, wherein the second locking position is displaced relative to the first locking position towards the first edge of the sleeve, and for passing at least one cylindrical protrusion under force towards the first edge of the sleeve from the first locking position to the second locking position. The at least one cylindrical protrusion and the at least one cutout are arranged such that when the pull-out element is connected to the sleeve by means of the at least one cylindrical protrusion and the at least one cutout in the first locking position, the sleeve extends beyond the first base of the pull-out element by at least its first part.

The invention further relates to an applicator comprising a cylindrical actuating element and a cylindrical housing, wherein the actuating element comprises a base and an inner tube which is an integral part of the base and which further comprises at least one slide for guiding at least one cylindrical protrusion. The at least one link has a first transverse groove at a first end of the link remote from the base of the actuator for locking the carrier in the extended position when the at least one cylindrical protrusion of the retractable carrier element is in the first locking position. The control element is adapted for pivotal connection to the housing. The housing has a first edge remote from the base of the actuator and is adapted for mounting on the inner tube of the actuator and for pivotal connection to the actuator and includes at least one helical cutout arranged on the inner wall of the housing for guiding the at least one cylindrical protrusion. The applicator further comprises a carrier according to the present invention and a stop disposed on the first edge of the housing, the stop being adapted to contact the carrier sleeve to provide back pressure to pass the at least one cylindrical protrusion from the first locking position to the second.

- 2 EN 2020 - 293 A3 locking positions. The first transverse groove at the first end of the inner tube link includes an extension for locking the carrier in the extended position when at least one cylindrical protrusion of the retractable carrier element is in the second locking position.

The dependent claims define further advantageous embodiments of the invention.

The mass carrier according to the present invention provides a connection of the pull-out element to the sleeve, which allows the pull-out element relative to the sleeve to slide out of the first locking position to the second locking position. This will allow more material to be ejected from the carrier and reduce the amount of unused material that remains in the conventional cup currently used in applicators at the end of use.

The carrier applicator of the present invention reduces the amount of unused mass remaining in the carrier by up to 33% at the end of use by a two-phase ejection mechanism, where in the final stage of use when the mass is consumed to the edge of the carrier and / or housing, thus, when it becomes difficult to apply or not applicable at all, the carrier according to the present invention allows the extension element to be extended relative to the sleeve from the first locking position to the second locking position, in which a substantial part of the otherwise unusable material is extended above the edge of the carrier and / or housing.

The base of the carrier is a substantially cylindrical pull-out element having a first base, a second base and a housing and a hollow sleeve which is arranged around the circumference of the housing of the pull-out element. The sleeve has at least a first edge and a first portion at the first edge and a second edge and a second portion at the second edge. The first portion may in a preferred embodiment form less than half the height of the sleeve, where the height of the sleeve is the distance between the first and second edges of the sleeve. In a preferred embodiment, the second part of the sleeve may form the remaining part of the height of the sleeve. The first edge of the sleeve and the first base of the pull-out element are oriented in the same direction.

The connection of the pull-out element and the sleeve to form the carrier takes place by means of at least one cylindrical protrusion which is arranged on the surface of the housing of the pull-out element and which fits into at least one cut-out arranged in the sleeve. The at least one cylindrical projection and the at least one cut-out are arranged such that when the pull-out element is connected to the sleeve by at least one cylindrical projection and the cut-out in the first locking position, the sleeve extends beyond the first base of the pull-out element by at least its first part; use.

The at least one cutout comprises means for locking the at least one cylindrical protrusion in the first locking position and in the second locking position and for passing the at least one cylindrical protrusion under a force in the direction of the first edge of the sleeve from the first locking position to the second locking position. These means in a preferred embodiment comprise at least one pair of opposite protrusions arranged to separate the first locking position from the second locking position, said protrusions being adapted to pass at least one cylindrical protrusion between the protrusions from the first locking position to the second locking position.

Two opposite protrusions may be arranged on the longitudinal sides of the slot to divide the slot into substantially two parts; a portion of the cutout in which the cylindrical protrusion is locked in the first locking position and a portion of the cutout in which the cylindrical protrusion is locked in the second locking position, the two portions being separated by a pair of opposing protrusions and a constricted space therebetween. The cylindrical projection can thus be locked by the edge of the cut-out and by the opposite projections, which serve as a barrier without the action of force and prevent the movement of the cylindrical projection. The cylindrical protrusion then passes through the opposite protrusions in the final phase of use, when the mass is consumed to the level of the edge of the carrier and the pull-out element needs to be moved from the first locking position to the second locking position.

In a preferred embodiment, the shapes of the cylindrical protrusion and the cutout may correspond to each other so that the cylindrical protrusion in the cutout is partially secured directly by the edge of the cutout. For example, the cutout may have a shape whose width corresponds to the diameter of the cylindrical protrusion and whose height

-3GB 2020 - 293 A3 corresponds to approximately twice the diameter of the cylindrical protrusion. One skilled in the art will appreciate how the shapes may correspond so that the cylindrical protrusion is in contact with the edge of the slot to secure it in the slot, but still allow the cylindrical protrusion to still move from the first locking position to the second locking position. It will also be apparent to one skilled in the art that direct contact of the cylindrical protrusion with the edge of the cutout is not necessary, and that securing the cylindrical protrusion in said cutout may be provided by other suitable means, such as other contact elements.

For example, the cut-out may in a preferred embodiment be arranged in the second edge of the sleeve. The means for locking the at least one cylindrical protrusion in the first position and in the second position may comprise at least two pairs of opposite protrusions. While in the second locking position the cylindrical projection can still be locked by the opposite projections and the edge of the cut-out, in the first locking position it can be locked by four projections which are arranged in two pairs. The advantage of arranging the cutout in the other edge of the sleeve is simpler and less expensive production.

Alternatively, the cut-out may be arranged in the wall of the sleeve so that the edges of the cut-out are formed by the wall of the sleeve on all sides. The cutout may in this embodiment comprise only one pair of opposite protrusions which are located approximately halfway up the height of the cutout so that the cylindrical protrusion is secured by the cutout edge from below and opposite protrusions from above in the first locking position and the opposite protrusions from below and the cutout edge from above in the second locking position . Here, "bottom" in said orientation means closer to the second edge of the sleeve and "from above" means closer to the first edge of the sleeve.

Advantageously, the pull-out element can be produced simultaneously with the sleeve so that at least one cylindrical protrusion of the pull-out element is made directly in the desired contact with the cut-out of the sleeve, e.g. by means of 3D printing.

At the same time, the opposite projections are adapted to pass the cylindrical projection between said projections from the first locking position to the second locking position under the action of a force. For example, they may be made of a suitable material and / or size to form a barrier without the force of securing the cylindrical protrusion in the first or second locking position, but will allow the cylindrical protrusion to pass therebetween under the action of the force. A suitable material may be, for example, a softer plastic or any material that allows transient deformation of the protrusions to pass the cylindrical protrusion.

In a preferred embodiment, in which the cutout is located at the second edge of the sleeve, the cylindrical protrusion may pass through two pairs of opposite protrusions. The first pair may be located near the second edge of the sleeve so that the cylindrical protrusion passes through the first pair of protrusions to the first locking position immediately during manufacture to connect the pull-out member and the sleeve. The second pair of protrusions then passes in the final phase of use, when the mass is consumed to the level of the edge of the carrier and the pull-out element needs to be moved from the first locking position to the second locking position.

In a preferred embodiment, the pull-out element comprises at least two, preferably opposite, cylindrical projections arranged on the surface of its housing. In a preferred embodiment, the sleeve comprises at least two, preferably opposite, cut-outs which are adapted to contact the at least two cylindrical projections for connecting the pull-out element to the sleeve.

The carrier further comprises means for securing the mass against release and subsequent falling out of the carrier. These means may be arranged on the first base of the pull-out element and / or on the inner wall of the first part of the sleeve.

In a preferred embodiment, the mass securing means are arranged on the first base of the pull-out element and may comprise one or more elements of different shapes and forms which secure the mass inside the carrier and minimize the possibility of its release and subsequent falling out of the carrier.

-4EN 2020 - 293 A3

In a preferred embodiment, these means comprise a transition region which is arranged on the first base of the pull-out element and a head adjoining it, preferably of a convex shape. In a preferred embodiment, the diameter of the head is smaller than the diameter of the pull-out element and larger than the diameter of the transition layer. The advantage of said arrangement is that the mass wraps the convex head evenly during pressing and is caught by the narrowed neck formed by said transition layer between the pull-out element and the head, which provides a more stable grip of the mass. In addition, the head and the transition area fill a relatively large part of the space of the carrier to be filled with mass, which further reduces the amount of mass that remains unused.

Alternatively or in addition, the means for securing the mass against release from the carrier may be arranged at least on a part of the inner wall of the first part of the sleeve, which is located at the first edge of the sleeve and may comprise, for example, protrusions or a structured surface. One skilled in the art will appreciate that the placement of the means on the inner wall of the sleeve is designed so as not to prevent the sliding element from sliding out of the first locking position to the second locking position.

In a preferred embodiment, the pull-out element may further comprise at least one opening passing through the pull-out element between its two bases for the removal of air compressed by the mass during its insertion. The at least one opening is preferably located in the head of the pull-out element. In a preferred embodiment, the at least one opening can be located at the circumference of the housing or directly formed in the circumference of the housing of the pull-out element. The pull-out element preferably comprises one opening arranged in the head and several openings arranged around the circumference of the housing of the pull-out element, these being preferably evenly distributed. The advantage of the presence of at least one opening is the removal of air when the material is introduced into the carrier, which further strengthens the securing of the material.

In a preferred embodiment, the sleeve may further comprise a first region of first diameter oriented in the direction of the first edge of the sleeve and the first base of the slider, and a second region of second diameter, wherein the first diameter is smaller than the second diameter, thereby creating an extension between the first and second regions. . The first part of the sleeve and the first area of the sleeve need not be identical. In a preferred embodiment, in which in addition the mass securing means comprise a transition region and an adjoining head, the height of the first region of the sleeve may be substantially the same as the height given by the common height of the two elements, i.e. the transition region and the head.

The carrier according to the present invention is primarily intended for application in an applicator, in particular for a cosmetic or medicinal preparation.

The applicator of the present invention comprises a cylindrical actuator and a cylindrical housing, the actuator comprising a base and an inner tube that is an integral part of the base and further includes at least one slide for guiding at least one cylindrical protrusion of the mass carrier retractable member. The at least one link has a first transverse groove at a first end of the link remote from the base of the actuator, which serves to lock the carrier in the extended position when the at least one cylindrical protrusion of the retractable carrier element is in the first locking position.

The control element is adapted for pivotal connection to the housing. The housing has a first edge furthest from the base of the control element and is adapted to fit on the inner tube of the control element and to be pivotally connected to the control element. The housing comprises at least one helical cut-out arranged on the inner wall of the housing for guiding at least one cylindrical projection of the mass carrier.

The applicator comprises a carrier according to the present invention and a stop arranged on the first edge of the housing. The stop is adapted to contact the carrier sleeve to provide a back pressure to pass the at least one cylindrical protrusion from the first locking position to the second locking position. The first transverse groove at the first end of the inner tube link includes an extension for locking the carrier in the extended position when at least one cylindrical protrusion of the retractable carrier element is in the second locking position.

-5GB 2020 - 293 A3

The applicator according to the present invention operates on the principle of two slides, which guide the carrier by means of a cylindrical projection from the retracted position, when the carrier and the substance inserted therein are inserted in the housing, to the extended position, resp. into a position for use in which the carrier and the substance inserted therein are pushed out of the housing for use. This is achieved in such a way that the at least one cylindrical projection of the carrier extension element is in contact, in addition to the at least one sleeve cutout, with at least one substantially longitudinal link which is arranged in the inner tube of the actuator and also with at least one helix or helix. a helical cutout which is arranged on the inside of the housing. During the relative rotational movement of the actuating element and the housing, the at least one cylindrical projection is guided simultaneously by at least one substantially longitudinal link and at the same time by at least one helix, whereby the carrier is extended from the retracted position to the extended position, resp. to the position for use.

In the extended position, the cylindrical projection, and thus the carrier, is locked against insertion into the housing in the first transverse groove at the first end of the link. This is a position for normal use where at least one cylindrical protrusion is in the first locking position.

The first transverse groove at the first end of the inner tube link includes an extension for locking the carrier in the extended position in the final stage of use, i.e. in which at least one cylindrical protrusion of the carrier extension element is in the second locking position.

In a preferred embodiment, the at least one substantially longitudinal link may further comprise a second transverse groove at the other end of the link which is closer to the base. The second transverse groove is oriented in the opposite direction as the first transverse groove and serves to lock the cylindrical projection, and thus the carrier, in the retracted position.

As mentioned above, the control element is adapted for pivotal connection to the housing. Complementarily, the housing is adapted for pivotal connection to the control element. The pivotal connection can be provided by complementary elements arranged on the housing and on the control element, for example a groove and a complementary protrusion. Said elements can also secure the housing after mounting on the inner tube of the control element.

The applicator of the present invention further comprises a stop arranged on the first edge of the housing. The stop is adapted to contact the carrier sleeve to provide a back pressure to pass the at least one cylindrical protrusion from the first locking position to the second locking position. As already described for the mass carrier, the at least one cut-out in the carrier sleeve is adapted to contact the at least one cylindrical projection for connecting the pull-out element to the sleeve. The at least one cutout comprises means for locking the at least one cylindrical protrusion in the first position and in the second position, the second position being displaced relative to the first position towards the first edge of the sleeve, and for passing the at least one cylindrical protrusion under force sleeves from the first position to the second position. When applied in the applicator, the effect of the force is ensured by the back pressure created by the contact of the sleeve with the stop. The stop creates a barrier to the sleeve, thereby providing a counter-pressure on further rotation of the housing and the slider, thereby providing the force required to move the at least one cylindrical protrusion from the first locking position to the second locking position. locking position. Due to the contact with the stop, the sleeve remains stationary and in this second extension phase, the pull-out element is extended to the second locking position, thus allowing another considerable part of the mass to be pulled out, which would otherwise remain unused in the carrier.

In a preferred embodiment, the stop can be provided as part of the housing. In this embodiment, the stop will form the end of the first edge of the housing, i.e. the edge remote from the base, which will have a diameter smaller than the housing itself. It will be apparent to a person skilled in the art that the diameter can only be reduced to a certain extent so as not to damage the mass introduced into the carrier.

Alternatively, the stop may be a separate element.

-6GB 2020 - 293 A3

The stop can be made of plastic or any suitable material. Advantageously, it can be made of metal for greater durability and / or as a decorative element.

In a preferred embodiment, the stop may be adapted to contact the first edge of the sleeve. In this embodiment, the diameter of the stop will correspond to the diameter of the first part of the sleeve so that the stop forms a barrier to the first edge of the sleeve.

In a preferred embodiment, where the carrier comprises an extension between the first and second sleeve regions, the stop may be adapted to contact the extension of the sleeve. In this embodiment, the diameter of the stop will substantially correspond to the first diameter of the first region of the sleeve so that the stop forms a barrier in contact with the extension of the sleeve.

After the at least one cylindrical projection has been moved to the second locking position, said projection no longer moves back to the first locking position. Further rotation of the housing and the actuating element pushes the mass carrier into the retracted position and extends the carrier to the extended position, the at least one cylindrical projection remaining in the second locking position.

In a preferred embodiment, the inner tube may comprise at least two substantially longitudinal slides, preferably opposite, and the housing may comprise at least two helical cutouts arranged on the inner wall of the housing, at least two slides and at least two helical cutouts arranged to correspond to their location. at least two cylindrical projections for guiding said at least two cylindrical projections, and thus also the mass carrier, from the retracted position to the extended position.

In a preferred embodiment, the applicator may further comprise a top part, for example in the form of a lid, or as a separate element which is removably connected to the housing.

The individual parts of the carrier and / or the applicator are preferably made of plastic. In other preferred embodiments, they may be made of metal or other suitable material. Different parts can be made of different materials.

The carrier according to the present invention, resp. the applicator containing said carrier can be used for any substance, in particular a mass of a cosmetic preparation, e.g. a lipstick, a concealer, or a medicinal preparation, e.g. a lip balm, or another medicinal preparation. However, the use is not excluded, for example in connection with industrial materials.

Examples of embodiments of the invention

In the following, lipstick will be described as an example of an embodiment of the present invention, but applications can also be applicators for cosmetics in general, applicators for medicines, but also, for example, applicators for industrial preparations.

Referring to Fig. 1, the mass carrier 10 according to the present invention comprises a pull-out element 11 having a substantially cylindrical shape with a first base 111, a second base 11Γ and a housing 112 and two opposite cylindrical protrusions 113 arranged on the surface of the housing 112. The carrier 10 further comprises a hollow sleeve 12 arranged around the circumference of the housing 112 of the pull-out element 11, which has a first part 121 at the first edge 121a and a second part 122 at the second edge 122a. The first portion 121 forms less than half the height of the sleeve 12, where the height of the sleeve 12 is the distance between the first edge 121a and the second edge 122a of the sleeve 12 and the second portion 122 of the sleeve 12 forms the remainder of the height of the sleeve 12. element 11 are oriented in the same direction.

The sleeve 12 further comprises means 114 for securing the mass 9 arranged on the first base 111 of the pull-out element 11. These means may also be on a part of the inner wall of the first part 121 of the sleeve 12 (not shown).

The sleeve 12 further comprises two opposing slots 123 adapted to contact two cylindrical protrusions 113 for connecting the slider 11 to the sleeve 12 by engaging the two opposing cylindrical protrusions 113 into two opposing slots 123 arranged in the sleeve 12.

The cylindrical projections 113 and the cut-outs 123 are arranged so that when the pull-out element 11 is connected to the sleeve 12 via these projections 113 and the cut-outs 123 in the first locking position 13, the sleeve 12 extends beyond the first base 111 of the pull-out element 11 with its first part 121 to secure the mass 9 in the carrier. 10 during use.

The cutouts 123 are in an exemplary embodiment arranged in the second edge 122a of the sleeve 12. The cutouts 123 comprise means 124 for locking the cylindrical protrusions 113 in the first locking position 13 and in the second locking position 14 and for passing the cylindrical protrusions 113 by a force towards the first edge 121a. sleeves 12 from the first locking position 13 to the second locking position 14.

In an exemplary embodiment, these means 124 include two pairs of opposing protrusions 125a. 125b arranged to separate the first locking position 13 from the second locking position 14, said protrusions 125a, 125b being adapted to pass the cylindrical protrusions 113 between the protrusions 125a. 125b from the first locking position 13 to the second locking position 14 under the action of a force.

In the exemplary embodiment, two opposing protrusions 125a, 125b are arranged on the longitudinal sides of each slot 123, thereby substantially dividing the slot 123 into two portions; a portion of the cutout in which the cylindrical protrusion 113 is locked in the first locking position 13 and a portion of the cutout in which the cylindrical protrusion 113 is locked in the second locking position 14, the two portions being separated by a pair of opposing protrusions 125a, 125b and a constricted space therebetween. Opposing protrusions 125a. 125b thus serves as a barrier without the action of force and prevents the movement of the cylindrical protrusion 113.

-8GB 2020 - 293 A3

The shapes of the cylindrical protrusion 113 and the cut-out 123 in the example correspond to each other so that the cylindrical protrusion 113 in the cut-out 123 is partially secured directly by the edge of the cut-out 123, in particular in the second locking position. Thus, the cutout 123 has a shape whose width substantially corresponds to the diameter of the cylindrical protrusion 113, and whose height corresponds to approximately twice the diameter of the cylindrical protrusion 113 and the height of the protrusions.

In the first locking position 13, each cylindrical projection is locked by four protrusions which are arranged in two pairs. The first pair is located near the second edge 122a of the sleeve 12 so that the cylindrical protrusion 113 passes through the first pair of protrusions to the first locking position 13 during manufacture to connect the slider 11 and the sleeve 12. The second pair of protrusions the mass 9 is consumed to the level of the edge of the carrier 10 and the extension element 11 needs to be extended from the first locking position 13 to the second locking position 14.

Alternatively, the cutout 123 may be arranged in the wall of the sleeve 12 such that the edges of the cutout 123 are formed by the wall of the sleeve 12 on all sides (not shown).
