DEVICE AND METHOD FOR TREATING A CONTAINER WITH A TREATMENT MEDIUM

TECHNICAL FIELD The present invention relates to an apparatus for treating a container having a container interior and a container exterior with a treatment medium, preferably for sterilizing the container in a beverage filling installation, as well as a sterilization apparatus having the apparatus and a method for treating a

Container interior and a container having outside container with a

Treatment medium, preferably for sterilizing the container in a beverage filling plant.

State of the art

Devices for treating containers with a treatment medium are known, for example from wet aseptic in beverage filling plants. Here, the containers to be cleaned undergo sterilization by means of a sterilization medium. For the sterilization of the

Container interior, the container is applied via a device with a sterilizing medium or with a sterilizing medium-vapor mixture. The sterilization of the container outside mostly takes place by passing the containers past stationary nozzles.

By passing the container to be treated on the stationary nozzles cleaning is ineffective. Thus, a large number of nozzles and a high throughput of sterilization medium are needed to allow sufficient sterilization of the container outside such as a container closure or a mouth area.

In order to overcome these disadvantages, it is occasionally attempted to simultaneously treat the container interior and at least one critical region of the container exterior.

For example, DE 10 2009 041 215 A1 shows a method and a device for stretch blow molding or blow molding and filling of sterile containers, wherein the gaseous medium conducted into and exiting from the container interior by deflecting surfaces in one above the Container opening arranged bell body are directed to the outer regions of the mouth region of the container. A secure admission of the outer areas, in particular due to the oblique introduction of the sterilization medium into the container interior and the corresponding unilateral leakage of the sterilization medium from the mouth of the container, can not be provided here only conditionally or for a liquid sterilization medium.

Further, JP 2001 276766 shows a washing nozzle device for washing a container, wherein a plurality of nozzles is provided at the tip of the main body thereof. The tip is thereby pushed into the container to be cleaned. Furthermore, the washing nozzle device has a nozzle arrangement branched off from the main body in the lower region, on the tip of which in turn a nozzle for cleaning an orifice region on the outside of the container is arranged. To clean the container this is pushed with the container opening down over the washer nozzle assembly. To achieve a circulating cleaning effect, the container should be rotated. For a rotary carousel-based plant, such a washing nozzle device is unsuitable.

Summary of the Invention It is an object of the present invention to provide an improved apparatus for treating containers.

This object is achieved by a device for treating a container having a container interior and a container outside with a treatment medium, preferably for sterilizing the container in a beverage filling plant, having the features of independent claim 1. Advantageous further developments emerge from the subclaims.

Brief Description of the Figures Preferred further embodiments of the invention are described by the following

Description of the figures explained in more detail. Showing:

Figure 1 shows schematically a perspective sectional view of an apparatus for sterilizing a container with a sterilizing medium; and

FIG. 2 is a schematic sectional view of a device for sterilizing a container with a sterilization medium in a further exemplary embodiment.

Detailed description of preferred embodiments In the following, preferred embodiments will be described with reference to the figures. In this case, identical, similar or equivalent elements are denoted by identical reference numerals. In order to avoid redundancy, the repeated description of these elements will be omitted in the following description.

FIG. 1 shows schematically a perspective sectional view of a device 1 for sterilizing a container, not shown here, with a sterilization medium. In this case, a nozzle element 2 has a centrally arranged inner nozzle 4 for acting on the container interior of the container to be cleaned with the sterilization medium. In this case, a connection line 6 for supplying the sterilization medium to the inner nozzle 4 is provided. For example, peracetic acid is used as the sterilization medium. But it can be another

Treatment medium or sterilization medium can be used.

Further, a nozzle ring 3 is arranged concentrically to the nozzle member 2. Between the nozzle ring 3 and the nozzle member 2, there is formed an outer nozzle 5 for pressurizing a portion of a container outer surface of the container. In this case, the outer nozzle 5 is provided by a provided on the nozzle ring 3 guide surface 32 and a parallel thereto provided on the nozzle member 2 counter surface 22 in the form of an annular gap 50. To supply the outer nozzle 5, a branch 7 is provided in the nozzle element 2, which connects a feed chamber 9 formed between the nozzle element 2 and the nozzle ring 3 with the connecting line 6. The feed chamber 9 is in this case for supplying the

Sterilization medium provided to the outer nozzle 5 and opens into the annular gap 50. Between the nozzle ring 3 and the nozzle member 2, a seal 12 for sealing the supply chamber 9 is further arranged.

An annular gap 50 with a constant flow cross-section is provided by the guide surface 22 and the mating surface 32 arranged in parallel. The guide surface 22 arranged on a rim 30 directed in the direction of the central axis M of the device is inclined inwardly with respect to the center axis M such that the sterilization medium flowing through the annular gap 50 strikes the region of the container exterior to be cleaned. Due to the design of the outer nozzle 5 as an annular gap 50, the sterilization medium can be passed over the full circumference of the nozzle ring 3 at the same time directly onto the area of the container outer side 104 to be cleaned. The treatment medium emerging from the outer nozzle therefore strikes the outside of the container directly, without making a "detour" over the container interior. Furthermore, the nozzle element has an additional line 8, whereby the guided to the inner nozzle 4 partial flow of the sterilizing medium pure steam or saturated steam is added. The pure steam or saturated steam is mixed with the sterilization medium in a mixing region 44 of the inner nozzle 4. In order to ensure uniform distribution of the

To allow sterilization medium in the pure steam or saturated steam and to provide suitable flow conditions, in particular suitable flow velocities of the pure steam sterilization medium mixture are in the mixing region 44, a first expansion stage 45 and a second expansion stage 46 each having a larger

Flow section arranged, wherein the second expansion stage 46 the

Outlet opening cross-section 42 of the outlet opening 40 of the inner nozzle 4 has.

The pointing in the direction of the container to be sterilized end face of the nozzle member 2 further comprises a discharge surface 24. Due to the dome-like shape of the discharge surface 24, the pure steam sterilizing medium mixture exiting from the container interior 102 is conducted to the outer nozzle 5. The sterilization medium emerging there partially mixes with the pure steam sterilization medium mixture, but primarily ensures safe removal of the pure steam sterilization medium mixture from the treatment zone. In this way it is ensured that particles entrained from the container interior 102 are not present on the container

Mouth region of the container 100 are deposited.

The nozzle element 2 and the nozzle ring 3 have a plastic. Alternatively, the nozzle element 2 and / or the nozzle ring 3 can also be made of a different material, for example a metal or a metal alloy, such as steel or stainless steel.

An inner nozzle 4 for pressurizing the container interior 102 of the container 100 and an outer nozzle 5 for applying the container thread 106 arranged on the container outer side 14 with the sterilization medium are arranged on the side of the nozzle member 2 facing the container 100 on the device 1.

The nozzle ring 3 is connected to the nozzle element 2 via a threaded portion 10, so that the nozzle ring 3 undergoes a change in position in the direction of the central axis M with a screwing movement of the nozzle ring 3 relative to the nozzle element 2. Due to the change in position of the nozzle ring 3 relative to the nozzle member 2, a distance between the disposed on the nozzle member 3 guide surface 32 and arranged on the nozzle member 2 counter surface 22 and thus the Flow cross section of the annular gap 50 formed as outer nozzle 5 are changed. As a result, the flow of the sterilization medium through the annular gap 50 can thereby be adjusted. The guide surface 32 is formed by a at the the container to be cleaned 100 facing side of the nozzle ring 3 arranged on this rim 30.

The inner nozzle 4 is supplied via the connecting line 6 sterilizing medium, which in the mixing region 44 with an introduced via an additional line 8 pure steam or

Saturated steam is mixed. Via the first expansion stage 45 and the second expansion stage 46 of the mixing region 44, the sterilization medium-pure steam mixture thus produced is supplied to the outlet opening 40 of the inner nozzle 4 and conveyed into the container interior 102 for sterilization.

The outer nozzle 5 is connected to a feed chamber 9, which by a in the

Nozzle element 3 separately trained branch 6 is supplied with sterilizing medium. To seal the feed chamber 9 on the side facing away from the container 100, a seal 12 in the form of a sealing ring is provided between the nozzle ring 3 and the nozzle member 2.

The supply of the connecting line 8 and the branch 6 is provided via a common sterilizing medium tank. Alternatively, they can be independent of each other

Sterilization medium supply arrangements may be provided.

At the direction of the container 100 to be sterilized facing end side of the nozzle member 2, a discharge surface 24 is provided. Due to the dome-like shape of the discharge surface 24, the pure steam sterilizing medium mixture exiting from the container interior 102 is conducted to the outer nozzle 5. The sterilization medium emerging there partially mixes with the pure steam sterilization medium mixture, but primarily ensures safe removal of the pure steam sterilization medium mixture from the treatment zone. In this way it is ensured that particles entrained from the container interior 102 are not present on the container

Mouth region of the container 100 are deposited.
