Description

technical field

The invention relates to a container according to the preamble of claim 1.

State of the art

Containers with one or more threads in the area of an opening are already known and used in a variety of forms and configurations. For example, in the DE 10 2012 100 075 A1 discloses a container with a hollow-cylindrical neck section with an external thread for receiving a closure lid.

In the EP 3 102 498 B1 further discloses a metal container and a method for manufacturing a metal container with a container thread.

object of the invention

The object of the present invention is to overcome the disadvantages of the prior art. In particular, a container is to be provided which, in a simple, material- and labor-saving manner, allows several closure and/or metering elements to be accommodated in the area of an output at the same time, with the aim being to ensure that the recorded closure and/or metering elements can be easily and intuitively removed can be removed from the container and placed there again.

solution of the task

The features according to claim 1 lead to the solution of the problem.

Advantageous configurations are described in the dependent claims.

In typical exemplary embodiments, a container consists of a receptacle and an outlet. In this case, the outlet has a tube which has an outside and an inside. The tube of the outlet protrudes from the receptacle.

The outlet pipe has an external thread on its outside. The external thread is stamped or formed into the tube in such a way that it is designed as an internal thread on the inside of the tube.

This means that the external thread forms a first tooth flank and a first thread valley, with the first tooth flank being formed as a second thread valley and the first thread valley as a second tooth flank of an internal thread (8) on the inside of the tube.

The external thread has a first thread entry and the internal thread has a second thread entry.

This results in the advantage that the tube of the outlet has both an external thread and an internal thread due to the embossing or molding of a thread. The external thread of the tube receives, for example, a screw cap with an internal thread via the first threaded entry, the internal thread of the tube simultaneously receiving, for example, a screw cap with an external thread.

Like the tube, both the first threaded entry and the second threaded entry protrude from the exception container.

In typical exemplary embodiments, the receiving container consists of a metal, a metal alloy, plastic, or glass. The receptacle is preferably made of an aluminum alloy. Aluminum alloys also offer good workability, with relatively thin wall thicknesses being able to be achieved with high stability. In addition, receptacles made from an aluminum alloy make it easier to emboss or mold the external thread, which also creates the internal thread at the same time. As a result, there is a double thread, which is the external and internal thread at the same time.

Of course, the internal thread of the tube is used to accommodate differently designed screw caps. The dosing area of the screw cap can be designed, for example, as a roller dispenser, or a ball dispenser, or a pump dispenser, or a foam dispenser, or a membrane dispenser. There are no restrictions here as long as there is a screw cap that can be screwed into the internal thread of the tube of the receptacle.

Furthermore, it is provided that the screw cap has a drinking and/or dispensing device, which can be opened for drinking or dispensing a medium from the receptacle and can then also be closed again.

Of course, it can also be provided that the screw cap has its own hinged lid.

Furthermore, it is provided in typical exemplary embodiments that the receptacle has a coating on an inner wall. This coating can be made of plastic or another suitable material. The task of the coating is to separate the medium to be filled in from the material of the receptacle. Embodiments of the receptacle are also provided which have no coating on the inner wall. This largely depends on the material from which the receptacle is made.

In addition, the coating of the inner wall can also be applied to the inside of the outlet or to the internal thread. This improves the seal between the internal thread and the screw cap in a simple and advantageous manner.

Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawings; these show in:

• 1 a schematically illustrated and sectional view of a receptacle 1;
• 2 a schematically illustrated and sectional view of the receptacle 1 after 1 with a screw cap 10 and a screw cap 11;
• 3 a lateral plan view of a receptacle 1.

example

In 1 a receptacle 1 is shown in a sectional view. The receiving container 1 has a cylindrical side wall 18 which forms a hollow bottom 17 on the one hand and an outlet 2 on the other hand.

The outlet 2 in turn forms a tube 3 which has an outside 4 and an inside 5 . An external thread 6 is stamped or formed into the pipe 3 on the outside 4 , which at the same time forms an internal thread 8 on the inside 5 .

The external thread 6 has on the outside 4 a first thread trough 13 and a first tooth flank 14 which are formed on the inside 5 as an internal thread 8 with a second thread trough 15 and a second tooth flank 16 .

The external thread 6 has a first thread entry 7 on the outside 4 . Likewise, the internal thread 8 has a second thread entry 9 on the inside 5 .

The first thread entry 7 of the external thread 6 is used to engage and receive an internal thread, for example from a screw cap 11.

The second thread entry 9 of the internal thread 8 is used to engage and receive an external thread, for example from a screw cap 10.

An inner wall 12 of the receptacle 1, like the inside 5 of the tube, has a coating which is not visible due to the illustration.

In 2 FIG. 14 is a sectional view of the accommodating container 1. FIG 1 shown, the screw cap 10 being accommodated in the internal thread 8 and the screw cap 11 being accommodated in the external thread 6 .

In the present exemplary embodiment, the screw cap 10 accommodated in the internal thread 5 of the receptacle 1 has a ball dispenser 19 which is used for metered delivery of a medium from the receptacle 1 via a movable ball.

The screw cap 10 is screwed into the internal thread 5 of the receptacle 1 with a screw cap external thread 20 .

The screw cap 11 engages with an internal thread 21 of the screw cap in the external thread 6 of the receptacle 1 . The screw cap 11 completely covers the screw cap 10 and the outlet 2 of the receptacle 1 with the tube 3 .

In 3 1 is a side plan view of the receptacle 1, with the view through the outlet 2 of part of an inner wall 12 of the side wall 18 being released.

All other reference numbers shown in this figure have been included in 1 and 2 mentioned and described, which is why they are not described again here. The reference symbols mentioned in the previous figures therefore also apply to 3 .

• Das Aufnahmebehältnis 1 wird mit einem Medium gefüllt. Danach wird in das Innengewinde der Schraubverschluss 10 mit einem Kugeldispenser eingeschraubt. Danach wird die Schraubverschlusskappe 11 über den Schraubverschluss 10 gestülpt und in das Außengewinde 6 des Aufnahmebehältnis 1 eingeschraubt. Die Aufnahme eines Außengewindes des Schraubverschluss 10 in das Innengewinde 8 erfolgt über den zweiten Gewindeeingang 9. Die Aufnahme eines Innengewindes des Schraubverschlusskappe 11 in das Außengewinde 6 erfolgt über den ersten Gewindeeingang 7.

Referring to the 1 until 3 the functioning of the device according to the invention is explained as follows:

• The receptacle 1 is filled with a medium. Thereafter, in the internal thread of the screw cap 10 with a Ball dispenser screwed in. Thereafter, the screw cap 11 is slipped over the screw cap 10 and screwed into the external thread 6 of the receptacle 1 . An external thread of the screw cap 10 is received in the internal thread 8 via the second thread entry 9. An internal thread of the screw cap 11 is received in the external thread 6 via the first thread entry 7.

Although only a few preferred embodiments of the invention have been described and illustrated, it is obvious that those skilled in the art can add numerous modifications without departing from the spirit and scope of the invention. In particular, both the screw cap 10 and the screw cap 11 can be designed and shaped differently, as long as the respective threads match the internal and external threads of the receptacle.

Of course, the shape of the receiving container can also be designed in a wide variety of ways.
