Dispenser for dispensing liquid, pasty or
powdery filling goods

The invention relates to a dispenser for dispensing liquid, pasty or powdery filling goods, consisting of one preferably flexible container with a closure which has two interlocking locking parts of which one is firmly connected to the container, and which are rotationally symmetrical relative to one another on a common axis of rotation have pivotable sealing surfaces, both closure parts being provided with openings in the sealing surfaces, which in a relative position for releasing the container contents are congruent, and which can be closed by pivoting the closure parts.

Various requirements are placed on such donors. From the manufacturer's point of view, it must be easy and inexpensive to manufacture, with little effort to assemble of the individual parts and for filling is desirable. The filling material must neither during transport nor during storage its moisture content still change in any way Become dirty or flow out of the container. Ease of use is paramount for the consumer. In particular, the removal of the product should only be done with one Be possible by hand without having to deal with screw caps or loose caps. Even so, the clogging of the shutter opening is supposed to due to the drying out of the residues contained therein, be excluded.

A tube closure is already known from DE-PS 861 666 become, in which a closure cap made of plastic material is snapped onto the tube neck in a rotationally symmetrical manner. Closure cap and tube neck each have an opening that opens into allow the contents of the tube to be removed from a congruent position. There is the disadvantage of such a closure in that the elastic closure part is arranged on the outside, so that the inner opening in the Schiiessstel1ung is closed by an outer elastic wall. When an internal pressure occurs, e.g. an unintentional If the container is compressed, the sealing pressure is released, the elastic wall section is arched outwards and the container contents penetrate outwards between the sealing surfaces.

In order to ensure adequate tightness, must therefore the initial sealing pressure must be large, which is why the closure is stiff. Drying residues of the contents can also clog the outer closure opening. In use, the quickly dirty the outer opening.

It is therefore the object of the invention to create a dispenser of the type mentioned at the outset that is reliable and tight Has closure, which can still be operated easily and with one hand. The dispenser should be able to be operated either in a stationary holding device or hands-free, without the locking function being impaired in any way. This object is achieved according to the invention in that the closure part, the opening of which faces the interior of the container, is made of a relatively elastic material, and that the other closure part is made of a relatively rigid material is made, so that when the closure is closed, when an internal pressure occurs, the wall of the elastic closure part is pressed sealingly onto the opening of the rigid closure part.

The sealing pressure is brought about by the fact that the wall of the elastic closure part rests against the rigid closure part under prestress. Obviously, when the closure is closed, the outer opening is sealed is intensified when an internal pressure occurs. The relatively elastic material can be, for example, a plastic, which due to its relatively small shear modulus and its inner Restoring efforts limited rubber el astically deformable, while the rigid material is a plastic with a relatively large Shear modulus can be. Therefore, the initial sealing pressure can be low and the closure can accordingly run smoothly.

Oe according to the embodiment is one of the two closure parts firmly connected to the container. It is also advantageous if one of the two closure parts opens into a pouring spout. The pouring spout allows convenient and clean removal of the contents.

A construction which is particularly advantageous in terms of design and ease of use is obtained when the one closure part is used Sheath element forms and if the other closure part is a than Hollow body formed core element, which is mounted in the jacket element, wherein the pivotable closure part is a Has handle device. Depending on the configuration of the closure parts, there can also be two pairs of openings in the sealing surfaces be provided so that in the closed position there is a double seal with respect to the interior of the container. This is particularly advantageous for very thin filling goods or for those which contain easily evaporating substances.

In the course of use, the pouring spout can become dirty or Residual content can dry up inside the pouring spout, which was previously prevented by using a clip-on outer cap, for example. In order to ensure that the dispenser according to the invention can be operated with one hand in this case as well, the core element or shell element is connected to a cover surrounding the closure, which together with the core element

ment or jacket element is pivotable and with the in Schiiessstel1ung the opening of the pouring spout can be covered. This prevents the filling material that is located inside the closure parts or the pouring socket from drying out can. This is particularly important for pasty products.

Depending on the design of the closure, the axis of rotation of the closure parts can be approximately parallel or approximately transverse to the longitudinal axis of the container get lost. The arrangement of the axis of rotation is particularly important when the container is in a stationary auxiliary device is used, which is pivotable relative to the container Holding fastener part. With a parallel arrangement of the Axis of rotation, the closure can then be opened by rotating the container about its longitudinal axis. On the other hand, if the axis of rotation is transverse arranged to the container, the container is pivoted about the axis of rotation, the container body forming a lever arm.

12 and 13 exemplary embodiments with a core element made of elastic material.

As shown in Figures 1 to 3, the dispenser 1 consists of essentially of a container 2 and a closure 3. In most cases, the container body is made of a flexible one Be made of plastic material so that the contents can be removed by squeezing the container. But it is It is also conceivable to manufacture the container from other materials, or additional removal devices such as plungers or Use propellant gas.

The closure consists essentially of a fixed to the Container connected closure part 5 and from a pivotable closure part 6. The two closure parts are as rotationally symmetrical, approximately cylindrical sleeves and rotate around the common axis of rotation 17. Openings 7 and 8 are arranged in the closure parts transversely to the axis of rotation 17, the fixed opening 7 being closable by turning away the pivotable opening 8. Depending on the circumstances, several pairs of openings can be made in the closure parts

7 and 6 may be provided. The pivotable closure part 6 opens into a pouring socket 9 ,. which facilitates the removal of the contents of the container. For removal, the two closure parts 5, 6 are rotated relative to one another until the pivotable opening 8 coincides with the fixed opening 7. Then the walls of the container are pressed together so that pressure is exerted on the contents inside the container will. The contents first pass through the two openings 7, 8 into a core cavity 18 and from there into the pouring socket 9.

The closure part, the opening of which faces the interior of the container is made of a relatively elastic material. This can be seen in the exemplary embodiment according to FIG the fixed closure part 5, since its opening 7 faces the interior of the container. In contrast, the pivotable closure part 6 is made of a relatively rigid material, so that the fixed closure part 5 pressed against the pivotable closure part 6 when an internal pressure occurs. In this way, a particularly secure seal is achieved when the closure is closed.

The pouring spout 9 is integrated into an outer cap 19, which in turn is made of a different material than the pivotable one Closure part 6 can exist. The individual components can be plugged together in the simplest possible way. the assembly the closure is made much easier.

The dispenser 1 can be inserted into a Wandhai sion 4 with the closure facing down. The wall bracket 4 is with a holding device 10 which holds the closure 3 positively receives. A recess 11 accommodates the pouring spout 9 and holds it in place at the same time. In this way For example, the outer cap 19 can have a cylindrical configuration without the closure in the holding device 10 being possible to rotate. To remove the contents of the container from in the wall bracket of the used dispenser must obviously only the container 2 can be rotated about its own axis until the

both openings 7 and 8 match. This ensures particularly simple operation, since both the rotary movement and the compression of the container with only one Can be hand run.

In the present exemplary embodiment, however, the outer cap 19 is also provided with a recessed grip 12 so that the closure can also be operated outside the wall bracket.

The recessed grip 12 engages in a corresponding projection 20 in the holding device.

The wall bracket 4 can be attached to a rear wall in various ways. You can, for example, screwed or can be glued or attached to the wall with the help of a suction cup. Instead of the wall bracket, any other stationary holding device can also be provided which can also be attached to a horizontal surface, e.g. on a table or on a washbasin. It is even conceivable that the closure part pivotable relative to the container, for example the outer cap 19 in the exemplary embodiment according to FIG. 1, has a fastening element with which the container can be fixed in place and which replaces the holding device. As such a fastener could for example a suction cup or a screw serve * It is It is also conceivable that the closure part, which can be pivoted relative to the container, has a self-adhesive surface with which the container can be fixed on a suitable base.

A modified embodiment is shown in FIGS a dispenser assembly shown. The axis of rotation 17 lies approximately transversely to the longitudinal axis of the container. The AusgiestülIe 9 runs in turn approximately at right angles to the axis of rotation 17, so that the pouring spout 9 runs approximately parallel to the longitudinal axis of the container » A locking pin 16 serves as a closure and to hold the pivotable closure part 6 in place. The fixed opening 7 is arranged laterally so that the pouring spout 9 transversely to the container

The longitudinal axis must be rotated in order to open the closure. The wall bracket 4 is adapted to the particular shape of the lock. The pouring spout 9 is also pushed through a recess 11, which, however, opens downwards. Even here the pivotable closure part 6 is held by the recess 11 on the pouring socket 9, while the container for Opening the shutter is pivoted. In the present exemplary embodiment, the fixed closure part 5 is again off made of a relatively elastic material. The fixed closure part can be a separate component or it can be directly be integrated into the container.

As shown in Figure 6, the container is in a position A, in which the container axis runs approximately vertically, closed. In position A, the opening of the pouring spout 9 is also through covered part of the holding device. For this purpose, the recess 11 is widened to form a type of sealing trough 21. As soon the container is pivoted in the direction of the arrow X, the pouring spout 9 also rotates as a result of the friction between the two Closing parts with and is pivoted out of the sealing trough 21. The opening of the pouring spout is released and this points approximately vertically downwards. The closure itself is only opened when the container reaches position B. Has. The * FuI! Can now be easily removed by pressing the walls of the container.

To close the dispenser, the container must be swiveled back in the direction of the arrow Y again. The pouring spout 9 is first pivoted back into the sealing trough 21 until it is there. The container is swiveled further until it has reached the approximately vertical position A again. In this embodiment, too, the dispenser can be removed from the wall bracket at any time in the open or closed state with a handle. Under certain circumstances it is even desirable that the container only remains in the wall bracket in the rest position and for the opening process, and then to be removed for use of the contents.

FIGS. 7a and 7b show two exemplary embodiments which also have all the features of the dispenser according to the invention, but in which not only the axis of rotation 17 of the closure parts but also the pouring spout 9 run approximately parallel to the longitudinal axis of the container. In the embodiment according to the figure 7a, the openings 7 and 8 are not arranged transversely, but parallel to the axis of rotation 17. A handle bar 13 also facilitates the operation of the lock here and can also be used to Serve holding in a stationary holding device. The openings 7 and 8 are arranged eccentrically on a common diameter. The pivotable closure part 6 is rotated so-Tange until the two openings coincide. When the closure is closed, the fixed closure part 5 made of elastic material pressed onto the opening 8 like a membrane. The embodiment according to FIG. 7b has a closure similar to that shown in FIG. 1, for example. Only that The pouring spout is designed as a direct extension of the core element.

FIGS. 8 to 10 show an exemplary embodiment in which the pouring spout 9 is firmly connected to the container 2. In the exemplary embodiment, the pivotable closure part 6 is again arranged within the fixed closure part 5. The closure, however, has two pairs of openings 7, 8 or 7 ¹ and 8 ¹ , so that the core cavity 18 is sealed twice. The pivotable closure part 6 is integrated in a cover 14 with which the pouring spout 9 can be completely covered.

The cover 14 has an inwardly facing trough 23, the wall of which is provided with a slot 22 in the plane of the Pouring spout 9 runs. The inner diameter of the cover 14 is dimensioned such that when the pouring spout is covered, the Opening 15 of the pouring spout closed by cover 14 will. In this way, the filling material located in the pouring spout is prevented from drying out.

The attachment in the wall bracket 4 is in this version basically the same as in the other exemplary embodiments.

Since, in the exemplary embodiment according to FIG. 8, the sealing surfaces which are in contact with one another are approximately conical, without how e.g. in Figure 4 a locking pin holds the pivotable closure part in place, a safety device must be used for the pivotable Closure part may be provided. This securing is expediently carried out by the fact that the contacting one another is used to press the seal tightly Sealing surfaces interlocking retaining ribs 24 running transversely to the axis of rotation are provided. These retaining ribs prevent that the pivotable closure part 6 can move axially without the pivoting being impaired. There the fixed closure part 5 is made of an elastic material, the pivotable closure part can be made of rigid Material are pressed into the fixed closure part so that the retaining ribs snap into one another. This also significantly simplifies the assembly of the closure.

FIG. 9 shows the dispenser closure with the pouring spout 9 pivoted in. By rotating the container about its own axis, the pouring spout 9 is pivoted out of the slot 22 and released, as shown in FIG. They are in this position too. Openings 7, 8 or 7 ', 8 ¹ congruent so that the filling material can be removed. Similar to the exemplary embodiment according to. FIGS. 4 to 6 could also, here the pouring spout 9 be covered by the stationary holding device 4.

FIG. 11 shows a further exemplary embodiment in which the pouring socket 9 is firmly connected to the container 2. The Ausgießstül Ie is not provided with a cover as in the exemplary embodiment according to FIG. 8. Instead of a recessed grip, the pivotable closure part 6 is provided with a grip strip 13 which would enable the pivotable closure part 6 to be fixed in a holding device. There the pouring spout 9 moves when the container is rotated,

the recess in the holding device would have to be accordingly be dimensioned.

FIG. 12 shows an exemplary embodiment in which, similarly to that shown in FIG. 4, the core element, which is the fixed closure part 5 corresponds, is made of an elastic material. The pivotable closure part 6 is a jacket element formed and provided with a AusgießstülIe 9. Additionally A fixed cover 14 can close the opening of the pouring spout when the closure is closed.

In the embodiment according to Figure 13 is also the core element made of elastic material. The core element here, however, corresponds to the pivotable closure part 6, while the closure part 5 made of rigid material is firmly connected to the container.
