Technical area

The invention relates to a container packaging.

State of the art

Container packaging comprising a container, a closure cap and an applicator fixedly connected to the container shoulder for dispensing the contents stored in the container are well known in the prior art. For ease of handling in the application, the dispensing opening of the applicator is often positioned eccentrically to the container main axis. Problems prepares in such cases, the tight closure of the discharge opening after removal of contents.

JP 2000109109 A discloses an applicator unit which can be screwed onto a container and has an output unit arranged eccentrically to the central axis of the container. For closing the dispensing unit, a cap which can be plugged onto the applicator unit and has an elliptical shape is provided. The closure cap has at least two protrusions which project inwards from the closure cap bottom and which seal the opening of the dispensing unit when the closure cap is attached. Due to the elliptical shape of the closure cap a precise fit of one of the extensions is ensured on the opening of the applicator in each case. The closure means either engage in the opening of the applicator or they surround the corresponding opening of the dispensing unit.

DE 689 06 136 T2 relates to a dispenser for pasty products with a protective cap and a dispenser cap, wherein the dispenser cap has an eccentric to the central axis of the dispenser arranged, lateral dispensing tube and a push button, which is connected to an actuating device of the dispenser. The protective cap has on its inner wall at least one guide ramp, a guide groove adjoining the guide ramp and a located at the end of the guide channel

Closure means with which the opening of the dispensing tube can be sealed. When attaching the protective cap guide ramp and guide channel ensure that the dispensing tube is positioned accurately to the closure means. - -

From the documents CN 103402883 A, JP 2002321755 A and EP 1 837 286 AI further variants of closure caps for applicators with an eccentric dispensing tube are known. To close the dispensing opening, these documents propose caps fitted to the applicator.

Despite these approaches known from the prior art, there is still a need for container packaging with a dispensing opening positioned eccentrically to the container main axis for the product to be stored in the container, whereby the dispensing opening should be designed so that it can be easily closed after a removal of contents.

Presentation of the invention

This is where the invention starts. It is intended to provide a container packaging with an eccentrically positioned to the container main axis discharge opening for the stored in the container contents, the output opening after a removal of contents should be easy to close tightly. This task will

solved according to the invention by the container packaging according to independent claim 1. Further advantageous aspects, details and embodiments of the invention will become apparent from the dependent claims, the description and the drawings.

The present invention provides a container packaging comprising a container for receiving a filling material and a closure cap available. The container comprises a container body, a container shoulder and an applicator fixedly connected to the container shoulder. The applicator has an applicator base section and an applicator dispensing section with a dispensing opening. In the area of

Applikatorbasisabschnitts, the applicator has an external thread. The

Closure cap has a shell portion and a lid portion and is equipped in its shell portion with a corresponding with the external thread of the Applikatorbasisabschnitts internal thread. The discharge opening of the

Applicatorausgabeabschnitts is offset from the axis of rotation of the external thread of the

Applicator base section arranged. The cap has in the

Mantle portion facing portion of its lid portion concentric with

Rotary axis circumferential groove, wherein the groove with the applicator output section cooperates such that at one with the help of the external thread of the

Applicator base section and the internal thread of the shell section of the

Closure cap screwing the closure cap with the container - -

Applicator output section engages with its output opening in the groove and the discharge opening is closed in the groove.

Under the axis of rotation of the external thread of the Applikatorbasisabschnitts is understood to be the axis about which the closure cap is rotated when, by the interaction of the external thread of the Applikatorbasisabschnitts and the internal thread of the

Sheath section of the closure cap Screwing the closure cap to the container takes place. If the closure cap is screwed to the container, that is, the closure cap is placed on the container, the axis of rotation of the external thread of the Applikatorbasisabschnitts coincides with the axis of rotation of the internal thread of the skirt portion of the cap.

With respect to a planar projection of the closure cap in a direction parallel to the shell portion of the closure cap, the axis of rotation of the internal thread of the shell portion of the closure cap and with appropriate orientation during

Screwing the cap and container also the axis of rotation of the external thread of the Applikatorbasisabschnitts through the center of the flat projection of the cap. The container packaging according to the invention ensures an uncomplicated and at the same time secure closing of the dispensing opening of the applicator after a removal of filling material. When screwing the cap on the container no special alignment of the cap needs to be observed. Since in the jacket portion facing portion of the lid portion of the cap arranged groove concentric with the axis of rotation, engages the

Applicator dispensing section irrespective of the orientation of the cap when placed on the container in the groove and after screwing the

Closure cap on the container in the groove tightly closed. The filling material is preferably a paste, a cream, a gel or a liquid.

Preferably, the applicator is formed integrally with the container shoulder. A one-piece design of applicator and container shoulder brings manufacturing advantages. The container shoulder is connected in this embodiment in a known manner, for example by welding to the wall of the container body. - -

The closure cap is preferably designed as a molded part made of plastic. The production of caps as molded plastic parts is established and therefore simple and inexpensive to perform. According to a preferred embodiment, the container and the applicator made of plastic or metal, in particular of a plastic laminate, of aluminum or of an aluminum alloy. On the one hand, the abovementioned materials have favorable properties during the production process and, on the other hand, advantageously provide the flexibility of the container wall desired for dispensing the contents.

Also preferred are embodiments according to which applicator and

Container shoulder are not made in one piece, but the applicator is firmly connected to the container shoulder, in particular aufprellt on the container shoulder. Also, the manufacturing processes required for this purpose are established, which is why applicator and container shoulder can be connected inexpensively and safely. Particularly preferably, the applicator can be produced in these cases as a molded part made of plastic.

In the embodiments in which the applicator and container shoulder are not made in one piece but the applicator is firmly connected to the container shoulder, the container and applicator can also be made of different materials. Are also container shoulder and container body is not formed in one piece, but are connected to each other only in the course of the manufacturing process, then basically container body and container shoulder can be made of different materials. Particularly preferred for the training of the

Applicator, the container shoulder and the container body, the materials plastic or metal, especially aluminum or an aluminum alloy used. On the one hand, the abovementioned materials have favorable properties during the production process and, on the other hand, advantageously provide the flexibility of the container wall desired for dispensing the contents.

According to a particularly preferred embodiment of the present invention, the container is a tube, the container body is a tube body and the container shoulder is a tube shoulder. The invention

Cooperation of closure cap and container or of the groove and applicator opening is particularly well suited for sealing tubes.

According to a further preferred embodiment, the groove has a width B and the dispensing opening has an outer diameter A, the width B of the groove being at most 1.5 ×, preferably at most 1.2 ×, particularly preferably at most 1 ×, _ _

in particular, preferably at most 1.05 times the outer diameter A of the

Issue opening is. In this case, under the outer diameter A of the dispensing opening, the extent of the dispensing opening including the applicator in the region of the dispensing opening in the direction of a center of the planar projection of

Cover section of the cap containing straight lines understood. The width B of the groove is understood to be the extent of the groove in the direction of a straight line containing the center of the planar projection of the cover section of the closure cap. In the case of a conically tapering in the direction of the lid portion groove whose maximum width is meant, ie the width of the groove at its end remote from the lid portion. Of course, these definitions are always based on a corresponding orientation of the cap and container during their screwing, ie a coincidence of the axis of rotation of the external thread of the Applikatorbasisabschnitts and the axis of rotation of the internal thread of the lateral surface of the cap.

Finally, embodiments are particularly preferred in which the center of the dispensing opening is more than 25% of the outer diameter AD of the

Applicator base portion is formed offset relative to the axis of rotation D to the outside. Under "OD of the applicator base section" is the maximum

Outer diameter of the Applikatorbasisabschnitts including there arranged

Externally threaded understood. The center Z of the discharge opening represents the center of the expansion of the discharge opening, including the applicator wall in the region of the discharge opening in the direction of a center of the planar projection of the

Also in this case, it is assumed that a corresponding orientation of the closure cap and container when screwing them, ie a coincidence of the axis of rotation of the external thread of the Applikatorbasisabschnitts and the axis of rotation of the internal thread of the lateral surface of the closure cap. As already stated several times, the dispensing opening of the applicator is not in the region of the axis of rotation of the external thread of the applicator base portion, but is arranged offset therefrom. Relative to the axis of rotation, the dispensing opening is thus always offset outwards in the direction of the wall of the container body. This facilitates the application of contents to any type of application surface. These benefits are particularly evident when the dispensing opening is more than 25% of the total

Outer diameter of the Applikatorbasisabschnitts offset relative to the axis of rotation D is formed outwardly, more preferably by more than 33% and more preferably by more than 40%. - -
