Description

The invention relates to a roll-on dispenser.

Roll-on dispensers are typically used as deodorants and have a container for receiving a deodorant liquid to be dosed and a dosing ball which is rotatably held in a socket and via which the liquid can be dosed. Roll-on dispensers also have a cap that is placed on the container and covers the dosing ball.

With conventional roll-on dispensers, it is usually difficult to refill the container.

Proceeding from this, the invention is based on the object of specifying a roll-on dispenser which is easy to refill and at the same time also offers a high level of dosing convenience.

The object is achieved according to the invention by a roll-on dispenser with a container, with a socket for holding a dosing ball and with a closure cap which, when fitted, covers at least part of the socket and thus the dosing ball. The socket is formed as a self-contained component and includes an internal fastener for releasably securing the socket to the container. Furthermore, the socket has an outer fastening element for the detachable fastening of the closure cap on the socket.

The mount is therefore designed in the manner of an adapter, which is arranged as an independent structural unit between the container and the closure cap.

Due to the detachable attachment of the socket to the container, it can be easily removed from the container, so that the container can be refilled. It is therefore a refillable roll-on dispenser.

Because the socket also has the outer fastening element for releasably fastening the closure cap, the socket itself simulates a conventional bottleneck of a container of a conventional roll-on dispenser. The container itself therefore does not need to have any fasteners for the closure cap. As a result, the design degrees of freedom are increased. In particular, this is also reflected in the fact that the socket has the largest possible diameter to accommodate the largest possible dosing ball. This achieves a high level of dosing convenience.

In a preferred embodiment, at least the inner or the outer fastening element and preferably both fastening elements are designed as twist-lock fasteners. This means that twisting clockwise or anti-clockwise is required for fastening and for loosening. A twist lock is therefore formed. This is designed, for example, as a bayonet catch.

In a preferred embodiment, the outer fastening element and preferably also the inner fastening element are designed to form a screw connection and for this purpose has at least one section of an external thread or internal thread. Corresponding rotary closure elements, in particular threaded sections, are arranged on the closure cap and on the container. At least part of an internal thread is therefore formed in the closure cap and at least part of an external thread is formed in the case of the container. Due to the configuration in the manner of a screw cap both for fastening the socket to the container and for fastening the closure cap to the socket, the individual elements can be connected to one another by simply screwing them on.

In a preferred embodiment, the container has a container opening and the socket has an opening for inserting the dosing ball. The two openings have at least largely and preferably exactly the same diameter. A largely identical diameter is understood here to mean that the two diameters differ from one another by no more than 20%, preferably by no more than 10% or also by no more than 5%.

This measure enables the largest possible dosing ball diameter. At the same time, the container opening is chosen to be as large as possible, so that easy refilling is made possible.

In an alternative embodiment, the diameter of the opening of the mount is larger than the diameter of the container opening. An increase in diameter therefore takes place via the socket.

Preferably, the roll-on dispenser generally has its largest diameter in the area of the socket.

In a preferred embodiment, there is a child safety device between the socket and the container educated. This means that in order to release the holder from the container, a safety device must also be overcome in addition to a rotary movement. For this purpose, child safety elements are specially designed on the container and on the socket, which engage in one another in a form-fitting manner and prevent twisting. In order to release these securing elements, it is necessary and sufficient to press the socket together so that it is deformed into an oval shape and the form fit between the two securing elements is thereby eliminated.

In an expedient embodiment, the socket has a lower section which is oriented towards the container. In the direction of the cover, the lower section is followed by an upper section. The outer fastening element is typically formed on the upper section and the inner fastening element on the lower section.

The lower section is preferably somewhat widened compared to the upper section and preferably forms an intermediate ring which is not covered by the closure cap when it is in place and which therefore remains visible between the container and the closure cap.

The configuration of this intermediate ring offers several advantages both in terms of functionality and in terms of design.

The closure cap covers the upper section when it is in place. The upper section typically has the holder for the dosing ball. An annular shoulder or an edge is preferably formed between the upper section and the lower section, on which the closure cap preferably rests when it is in place. In this respect, this edge forms a stop for the closure cap and thereby also limits the opening of the closure cap onto the socket.

In a preferred embodiment, the intermediate ring is aligned with the closure cap and/or with the container. This achieves an appearance similar to that of conventional roll-on dispensers, in which the container typically transitions seamlessly into the closure cap. This is achieved by the aligned arrangement, in particular both to the container and to the closure cap. This means that the intermediate ring has the same outer diameter as the container in its upper area and as the closure cap in its lower area.

The intermediate ring expediently has a height of more than 0.5 cm, in particular more than 1 cm. Specifically, it has a height of, for example, a maximum of 3 cm or a maximum of 2 cm. Height is understood to mean the extension of the intermediate ring in a longitudinal direction of the roll-on dispenser. This longitudinal direction is defined by the direction in which the container extends from a container bottom in the direction of the closure cap. Due to this great height, several functions can be integrated into this intermediate ring.

The intermediate ring is also preferably of cylindrical design, which is advantageous for the integration of the functions described below.

According to a preferred variant, the child safety device is designed in the area of the intermediate ring. In particular, the intermediate ring has two opposing pressure surfaces which are pressed against one another and thus compressed in order to release the child safety device. This deforms the socket in the area of the intermediate ring and the child safety lock is released. The intermediate ring is preferably flattened in the area of the pressure surfaces—in contrast to the cylindrical shape. However, the intermediate ring is otherwise cylindrical. In comparison to the rest of the intermediate ring, the two pressure surfaces preferably have a different surface structure, for example roughening or grooving.

In a preferred embodiment, the intermediate ring also has at least one open area for inscription and in particular two opposite open areas. The two free surfaces are preferably arranged between the two pressure surfaces in the circumferential direction of the intermediate ring.

The open spaces therefore offer the possibility of applying a customer-specific logo. By designing the socket in the manner of an adapter, a wide variety of designs and variants can be created for different customers in a modular manner, with the sockets differing in terms of their labeling, color scheme, etc., but otherwise being identical, which keeps tool costs low .

• 1A, 1B zwei Seitenansichten eines Roll-On Dispensers, die um 90° zueinander verdreht sind,
• 2A, 2B Explosionsdarstellungen zu den Abbildungen in den 1A, 1B,
• 3A -3F unterschiedliche Darstellungen der Fassung, nämlich 3A eine Aufsicht von oben, 3B eine erste Schnittansicht, 3C eine um 90° gedrehte Schnittansicht, 3D eine Seitenansicht korrespondierend zur Schnittansicht gemäß der 3B, 3E eine um 90° gedrehte Seitenansicht korrespondierend zur Schnittansicht gemäß der 3C sowie 3F eine Ansicht von unten auf die Fassung.

An embodiment of the invention is explained in more detail below with reference to the figures. These show:

• 1A , 1B two side views of a roll-on dispenser rotated by 90° to each other,
• 2A , 2 B Exploded views for the illustrations in the 1A , 1B ,
• 3A - 3F different representations of the version, viz 3A a view from above, 3B a first sectional view, 3C a sectional view rotated by 90°, 3D a side view corresponding to the sectional view according to FIG 3B , 3E a side view rotated by 90° corresponding to the sectional view according to FIG 3C as 3F a bottom view of the frame.

The roll-on dispenser 2 shown in the figures is generally made up of a container 4 , a socket 6 and a closure cap 8 . The socket 6 is designed as an independent component in the manner of an adapter and is arranged between the container 4 and the closure cap 8 .

The socket 6 generally comprises an upper portion 10 and a lower portion forming an intermediate ring 12 which can be seen. The upper section 10 has an external thread 14 as an external fastening element and the lower section has an internal thread 16 as an inner fastening element (cf 3B , 3C ).

Correspondingly, the closure cap 8 has an internal thread (not shown here) and the container 4 has an external thread 18 .

Insofar as threads are generally spoken of here, this is understood to mean at least one threaded part extending over a section of the circumference. In the exemplary embodiment, the external thread 14 is designed as a fully circumferential thread. The internal thread 16 is preferably also designed as a completely circumferential thread turn.

In the simplest case, the counter-threads for this are formed by short thread sections, which can also be reduced to simple lugs or webs.

It is essential that the mutually corresponding threaded fasteners allow a screw connection between the socket 6 and the container 4 on the one hand and between the socket 6 and the closure cap 8 on the other hand.

Between the socket 6 and the container 4 there is also a child safety device, which is not explained in any more detail here, in a conventional manner.

The intermediate ring 12 has a height H which is, for example, in the range between 0.5 and 3 cm and in particular in the range between 1 cm and 2 cm.

On its peripheral side, the intermediate ring 12 has two opposing pressure surfaces 20 and free surfaces 22 between these. The intermediate ring 12 and thus the socket 6 can be pressed together via the pressure surfaces 20 so that the child safety device can be released. The open spaces 22 are used for applying logos, for example.

The mount 6 has an opening 24 towards the closure cap 8 . Furthermore, the container 4 has a container opening 26 . These two openings 24,26 preferably have the same diameter.

In the upper section 10 and specifically in the opening 24 a dosing ball not shown here is arranged. It is rotatably held within the socket 6. For this purpose, the upper section 10 tapers towards the top and thus encompasses the dosing ball protruding beyond the opening 24 so that it is held in a form-fitting manner.

As in particular from the representations of 3A , 3B and 3F, a support for the dosing ball is formed within the socket 6, which is formed by (three) struts in the exemplary embodiment.

How particularly well from the 3A , 3B as can be seen, the intermediate ring 12 is flattened in the area of the pressure surfaces 20 so that they can be gripped easily.

A shoulder is formed between the upper section 10 and the intermediate ring 12 . When fitted, the cap 8 extends to this paragraph and is aligned with the intermediate ring 12. As specifically from the 1A , 1B it can be seen that the intermediate ring 12 is still aligned with the upper area of the container 4. This then tapers, starting from the intermediate ring, to a container bottom.

In the exemplary embodiment shown, the closure cap 8 is flattened on its upper side, so that the roll-on dispenser 2 can also be placed upside down in the manner of an upside-down bottle. As an alternative to this, the closure cap 8 is provided, for example, with an eyelet for hanging up the roll-on dispenser 2 .
