Description

TECHNICAL AREA

The Invention relates to the field of dispenser tubes for liquid or viscous products, typically creams or pastes. It particularly concerns this Area of applicator tubes making it possible to use such products store, donate and apply to a vehicle such as the skin (Sunscreen, skin care cream, slimming cream, self-tanning cream, Etc.).

STATE OF THE ART

donor for applying liquid or viscous products are already in great Number known. The dispenser head usually has a circular central opening, which is less suitable or unsuitable for a direct application of the product on the skin in the case of a cosmetic or dermatological product or on any carrier in the case of another product. One uses in this case the Palm or fingers as a means of application, with the disadvantages, that can be connected especially regarding hygiene and cleanliness.

Of the However, dispenser head may also have a variety of openings or not one centrally located opening exhibit. In this case, the dispenser head is a total of one Closure cap closed. This has because of the not individually sealed openings As a result, depending on the type of packaged product, product losses or soiling on the outer surface of the dispenser head can come, in a more or less strong and permanent way Extent. In addition, a tight seal can be difficult to accomplish, unless strong manual forces are used to close and open, the far over the normal strength that is for one User usually is considered acceptable. Finally, depending on the type of In the dispenser packaged product may encounter the problem that the openings clog gradually.

On On the other hand, it is advantageous to develop dispensing heads during the process Application of the product additionally ensure a certain massage of the skin, for example by to arch your head and rounded ridges, which makes sense to the opening are arranged around. However, the massage effect achieved remains limited.

you can also container use, usually vials, their head with a ball or role with largely spheroidal formed wall, which is free around its center or rotates about an axis and the by putting on and moving on one given carrier performs a rotational movement and in the container near the ball or roll contained product to the surface of the carrier drives. This ball or roller will open with a certain force the carrier pressed what the desired Massage effect leads.

Indeed these are usually around phial with more or less stiff walls, so that the field of application of such containers to the application of light liquid products limited.

The older one U.S. Patent 2,892,202 discloses a metal tube for applying pasty products, on which a plastic extension piece is provided, which can be reversibly screwed onto the tube neck, wherein the extension piece is provided with an applicator roller with a substantially spherical wall. To our knowledge the use of this donor seems to have been confidential and temporary.

The U.S. Patent 3,235,900 discloses a tube for applying pasty products having a thick, rigid tube head with a ball rotatable about an axis, which axis is materialized by two diametrically opposed shaft portions which are mounted in recesses recessed in the thick wall of the tube head. Due to the size and rigidity of such a tube head remains at the end of use much product in the interior of the tube, so that it is not possible to achieve a satisfactory release rate.

The The invention aims a dispenser with applicator with acceptable Indicate delivery rate, which has a real massage effect and viscous creams, typically sun creams or skin care creams, without the application of force able to apply.

PRESENTATION OF THE INVENTION

A first object of the invention is a tube for dispensing liquid, viscous, typically creamy or pasty products, by applying the products to a carrier, typically the skin, the tube having a dispensing head with a neck and a shoulder connecting the neck with a soft sheath , which is typically cylindrical, circular or elliptical in a soft mantle, and has a neck-mounted hub with a cavity connected to the interior of the tube and an applicator roller that rotates in the cavity by seating and moving on the carrier and that contained in the container Product up to the carrier drives, characterized gekennzeich net, that the extension piece is provided with a side wall, which comes to rest on the tube shoulder near the jacket end.

The Applicator pack according to the present invention is a tube with a soft tube coat, typically plastic or metal plastic: This can - easier as with a vial - a suitable Force on the coat can be combined with a suitable force on the wearer around the more or less viscous product to bring in the tube to the cavity, which then serves as a storage container for the delivery of the product, the product subsequently being from the applicator roll to the carrier is driven.

Unlike the in US 2,892,202 the tube is not only held by the tube neck: its peripheral part is held by a side wall, which is supported on the circumference of the tube shoulder in the vicinity of the tube jacket. As a result, the entire arrangement gets a more stable seat. The dispenser tube is thus less flexible and easier to handle.

According to the invention is separately a special attachment manufactured - comprising said cavity and a side wall - the neck of a standard tube head can be fixed by clipping on or screwing on. In the latter case may be the starting piece be provided with a fastening jacket whose diameter is slightly larger as the diameter of the tube neck. In such a geometric Embodiment, the side wall has a certain height, the slight is larger than that of the tube neck, since it covers the circumference of the cavity above the Tube neck is located, must connect to the circumference of the tube shoulder, which connects the end of the tube jacket with the tube neck. The attachment can be removed advantageously by unscrewing or unscrewing, so that the consumer can clean it. However, in should In this case additional funds for orientation of the extension piece be provided in relation to the tube, so that the applicator roll can rotate about an axis whose orientation relative to the remaining tube remains constant (repeatable orientation). at The orientation means are, for example, a screw thread of the neck of the tube arranged increase, which serves as a screw stop, by the forward movement counteracts the Schraubwulstanfangs the fastening shell, or also around a non-circular web resting on the tube shoulder, after screwing or after axial pressing in as a guide for the open end one with the extension piece connected shell portion, for example, the at the periphery of the cavity attached side wall.

According to the invention Applicator role partially housed in the cavity that They feel like putting on and moving the tube on a carrier the skin in the cavity can rotate while the packaged in the tube Product up to the carrier driving, wherein the product by an opening recessed in the wall of the cavity of the Inside the tube can flow to the cavity.

Of the Cavity and the applicator roll have a solid, at least repetitive Orientation opposite the rest of the tube and in particular with respect to the end weld, the after filling of the product the open end of the tube jacket is made. This end weld is elongated formed in a direction which the angular positioning of Rotary axis of the role can define. Since this seam however manufactured later is used, a reference system is used, which refers to an axis of Tube, usually supports an axis of symmetry of the tube neck or tube shell before the final seam is produced. It thus becomes a stable donor proposed, without surprise can be handled, because the applicator roll always the same orientation relative to the has remaining tube. This orientation is preferably so selected the applicator roll is about an axis parallel to the end seam rotates.

Preferably The applicator roller rotates about an axis so that its outer surface a stable lateral surface represents. It is rotationally symmetric about the axis. Preferably has the cavity at least in the lower part of a wall, which with an offset to the outside Adjusts to the general shape of the lateral surface of the applicator roll. These So wall is also rotationally symmetric to the same axis. The distance between the walls - the gap - is small and depending on the viscosity of the product to be donated. He is big enough thus the driving force dependent on the friction on the surface of the applicator roller from the viscous flow in this Cleft-dependent Pressure loss compensates. Preferably, it is at the same time small enough to prevent inadvertent leakage, i. to any outflow of the product without turning the applicator roll. Thereby the channel needs to supply product to the applicator roll not to be equipped with a valve. This distance is typically less than 2mm.

For small applicator tubes, it may prove useful to materialize the axis of rotation by, for example, providing the ends of the applicator roller with a shaft which rotates in a bore formed on the periphery of the cavity. In contrast, in a larger role, typically 50 mm in length or more and with a gap of a few tens of milli The roll does not need to be corrugated because it can move within the cavity without appreciably changing its general orientation (it typically remains stable at about 3 °). The roller thus moves "freely" in the cavity and can thereby rotate about an axis whose general orientation is largely constant. When the roll is placed on a wearer (typically the skin), it drives the product already in the gap of the cavity from the dispensing opening to the wearer. However, the roller is driven by placing it on the support to the "bottom" of the cavity and can close a part of the product discharge opening more or less. For further supply of product, it is sufficient to press on the soft tube wall and to stroke it with the roller on the carrier. Due to the absence of a fixed axis of rotation creates a variable gap between the wall of the cavity and the surface of the roller, which varies depending on the distance to the carrier and depending on the application force. A preferred embodiment of the invention is a dispenser tube having an applicator roller that does not have axial elevations or perforations materializing the axis of rotation and that moves "freely" within the cavity, thereby rotating about an axis of generally constant general orientation. This tube is presented in the examples below, placed vertically in a conventional manner, with the head up.

The Role can be filled completely or preferably hollow, whereby the dispenser becomes lighter. For the production the hollow roll can For example, two half shells are joined together. The role can be out a plastic such as polyolefin, a polymer material, a polyurethane foam, consist of a polyethylene foam. It can also be made of metal or Be glass. It can be smooth or have grooves on its surface, to carry the product easier.

To the Holding the applicator roll in the cavity is the wall of the cavity extended, typically again on the lateral surface, which has the same axis of symmetry as the applicator roller, above supported by a plane passing through this axis, so that a ring lip is formed, which holds the role in the cavity. Different words the space bounded by the cavity has a cross-section that a circular section with an angular amplitude greater than 180 ° corresponds. The difference between the angle amplitude and 180 ° corresponds twice the angular range of the annular lip. The lip is "above" the through the axis of symmetry going level and extends over a height - typically a few millimeters - the low is sufficiently sized so that the application area of the role as possible is great but enough for the lip to hold the roll in its cavity can. In addition, the lip preferably has a smaller width than Height and has a sufficiently large elasticity to hold the roll by pressing into the opening formed by the annular lip to be able to. The upper end of the lip may be flat and transverse to the tube axis run, wherein the application then preferably held transversely to the carrier Tube takes place. However, the upper end of the lip can also be a substantially flat upper wall parallel to a relative to the tube axis inclined (non-transverse) level, which may be the ease of use of Tube can improve when applying the product. typically, the upper wall of the lip is flat and supports itself on a plane, which includes an angle of 45 to 90 ° with the tube axis.

According to one preferred special embodiment of the invention, the dispenser tube near her head part on a cylindrical shell, the cylinder as axis an axis A and as orthogonal cross-section to the axis A has an ellipse and the main axis of the ellipse parallel to the Rotation axis B of the roller and perpendicular to the axis A of the cylinder runs. Preferably, the final Seal the tube, the end weld also parallel to Axis B arranged. The applicator roller is a cylindrical or axially symmetrical roller with a curved, largely spheroidal Wall, which like a gentle application of the product on a support the skin with one almost equally to one Generating line along distributed force allows.

Of the Cavity has a central opening, over the he communicates with the inside of the tube. For the easier Compensation of the entrained product flows are the walls the cavity and the roller preferably designed so that the Distance between these walls with coaxial arrangement of roller and cavity not completely constant is: he is near the opening smaller and larger at the ends of the roll.

Which Whatever shape the applicator roll has, the tube head is made, advantageously by a head provided with a simple neck largely irreversible with a cavity and applicator roll comprehensive approach which is a largely irreversible first fastener has, typically a fastening jacket with at least a Rastwulst with asymmetrical slopes, which formed continuously is or is not and complementary to a largely irreversible second attachment means which is arranged on the tube head, for example on the outer surface of the Neck part.

Advantageously, the cavity provided on the opening for connection to the tube interior is surrounded by a bottom of the wall of the cavity mounted sealing jacket, wherein the upper wall of the tube neck in the patent EP 1 292 504 above the tube neck is provided a transverse end wall with a cylindrical shaft whose diameter is slightly smaller than the outer diameter of the sealing jacket of the endpiece, wherein the cylindrical shaft extends to both sides of the transverse end wall.

advantageously, is over the tube head a closure cap provided which the applicator while the storage of the tube protects. is not the role with raises which act as rotation waves, they can be within the Move cavity, while ensuring the Tightness during the storage of the cap advantageously at its upper Wall is provided with internal ribs which, when the cap fixed on the tube head, come on the roll to concern and push the roller to the bottom of the cavity, so that the roller dispensing opening closes.

On This way results in a dense and inexpensive dispenser tube with applicator roller, both in terms of their use (by the soft tube wall, the product flow to be dispensed can be controlled be) as well as in terms of their production (the bottom of the cavity does not need to be equipped with valves or flaps as the easy molded and easy to manufacture and to assemble role itself acts as a closure. If the tube head with a reversible screw-on or clip-on end piece is equipped (where the extension the cavity and the applicator roll), other devices may also be used to guarantee the tightness during be formed of storage, for example, a system that two stable positions of the endpiece allows: a closed position, in the the donation opening is closed, and an opening position, in the the donation opening is open. For an elliptical tube as described above the extension typically be designed so that, for example, by rotation around 180 ° the axis of the tube neck changes from a configuration "open" to a configuration "closed".

Of course you can too Containers that have a head and a soft-walled body, such as bottle tubes (or Tottles), which are produced in particular by extrusion blow molding be provided with the roller and the cavity according to the invention are, i. with a peripheral wall directly connected to the soft container wall is connected or is supported by a side wall, which is located on End of the soft wall is supported.

One Another object of the invention is an applicator dispenser tube, characterized in that it comprises a tube such as one of the above has described which after filling with the to be donated filling a final weld given direction D, and that the applicator roll in predetermined Way is oriented with respect to the direction D of the end weld.

Preferably the tube is elliptical, with a major axis parallel to the axis of rotation B of the applicator roll, which in turn is largely parallel to the direction D of the end weld is.

EXAMPLES

Example 1 ( 1 and 2 )

The in 1 illustrated item is the headboard of a tube 100 for donating sunscreen by putting on the skin. The tube consists of a tube jacket 102 and a dispensing head, the dispensing head having one inside 103 the tube connected cavity 111 made of plastic and a roll 300 which rotates freely about an axis B perpendicular to the axis A of the tube head. By putting on and moving on the skin, the applicator roller rotates 300 around the axis B, forcing the product contained in the container forward until it reaches the skin. The tube coat 102 is made of plastic. The peripheral part 120 of the cavity 111 is from a sidewall 121 kept that in the end 104 of the soft coat 102 supported, more precisely over the bridge 109 at the edge of the shoulder 101 , The applicator roller 300 is largely irreversibly attached to the tube head, via the annular lip 119 which is an extension of the wall 112 of the cavity 111 represents.

The applicator roller 300 is in a cavity 111 housed in the tube head. It has a fixed orientation relative to the rest of the tube, especially the end weld 104 (Cf. 2 ), which is made after filling the product over the open end of the tube sheath. In this way, a stable donor tube is obtained, which offers a handling without surprise with always the same orientation with respect to the rest of the tube. The applicator roller rotates freely about the axis B parallel to the end weld 104 ,

The applicator roller 300 rotates about the axis B. It is rotationally symmetric about this axis. In addition, has the cavity 111 - at least at the bottom - a wall 112 slightly outwardly directed to the general shape of the shell surface of the applicator roll 300 adapts. Since the offset is not necessarily constant, it is supported approximately on an area that is rotationally symmetric to axis B. The distance between the walls is approximately 1 mm with a coaxial arrangement of roller and cavity in a sunscreen. As a result, the channel for supplying the applicator roll with product need not be provided with a valve.

To hold the applicator roller 300 in the cavity is the wall 112 of the cavity 111 extends and again supported on the lateral surface with the axis B as a rotational symmetry axis, via an annular lip 119 , which is located above a passing through the axis B level. The height of the lip of the ring 119 above this level is about 2 mm. The upper end of the ring lip 119 of the cavity 111 is flat and is supported on a plane transverse to the axis A of the tube.

The applicator roller 300 is a largely cylindrical roller which is rotationally symmetric about the axis B. It does not have any elevations or perforations in the axial direction that materialize the axis of rotation B. It moves "freely" in the cavity 111 and can rotate around an axis whose general orientation is largely constant.

The tube 100 has a tube jacket 102 elliptical cross section, wherein the major axis of the ellipse is also parallel to the axis B, which in turn is parallel to the end seam 104 has. In this way, one obtains an elongated applicator of cylindrical shape, which allows a gentle application of the product to the skin with a force distributed almost uniformly along a generatrix line.

The cavity has a central opening 113 about which he deals with the interior 103 the tube communicates.

The tube head is made by one with a neck piece 105 provided head 104 largely irreversible with a cavity 111 and the applicator roll 300 comprehensive approach 110 is connected. The starting piece 110 has a largely irreversible first fastener, typically a fastening jacket 118 with a continuous Rastwulst 117 which is complementary to one on the outer surface of the neck portion 105 arranged Rastwulst 106 has.

The on the cavity 111 provided opening 113 for connection with the tube interior 103 is from one down to the wall of the cavity 111 attached sealing jacket 130 surrounded, and above the tube neck 105 is a transverse end wall 107 with a cylindrical shaft 108 provided, whose diameter is slightly smaller than the outer diameter of said sealing jacket of the endpiece, wherein the cylindrical shaft extends to both sides of the transverse end wall.

Advantageously, a cap is above the tube head 200 provided, which the applicator roll 300 as well as protecting the entire head during storage of the tube. The flap is attached to the tube head by axial pressing and reversible clipping. After pressing is the inner wall of the open end 220 the cap 200 by the at the periphery of the shoulder 101 trained footbridge 109 guided and oriented.
