TEST CONTAINER FOR TESTING INSPECTION DEVICES

Abstract

A test container for checking container inspection machines, which inspection machines are suitable for examining at least a first category of containers for the presence of foreign bodies, with a man body in which a liquid is disposed, with a mouth via which the liquid is able to be introduced into the container, with a first closure by means of which the container is closed, wherein a foreign body which can be detected by the inspection machine is disposed in the container is provided. The container and/or the liquid disposed therein has a further substance or for example a transmitting device which can be detected by a user and/or by a detection device in order thus to distinguish the test container per se from another container of the category to be inspected.

Claims

1. Test container for checking container inspection machines, which inspection machines are suitable for examining at least a first category of containers for the presence of foreign bodies, with a man body in which a liquid is disposed, with a mouth via which the liquid is able to be introduced into the container, with a first closure by means of which the container is closed, wherein a foreign body which can be detected by the inspection machine is disposed in the container, wherein the container and/or the liquid disposed therein has a detection means which can be detected by a user and/or a detection device in order thus to distinguish the test container per se from another container of the category to be inspected, wherein the liquid prevents the multiplication of germs for a long period of time.

2. Test container according to claim 1, wherein the liquid has at least one substance with a germ-killing action.

3. Test container according to claim 1, wherein the liquid is similar in appearance and index of refraction to a product actually to used be.

4. Test container according to claim 1, wherein the liquid, in particular as a replacement for beer, is a denatured, coloured, high-percentage alcohol solution.

5. Test container according to claim 1, wherein the test container is a test container produced at least partially under sterile conditions.

6. Test container according to claim 1, wherein the liquid in the container has been introduced under sterile conditions and/or also a closure of the container has been manufactured and attached to the container under sterile conditions.

7. Test container according to claim 1, wherein the container has been subjected to heat treatment, in particular a heat treatment just below the boiling point for a few hours, which effectively slows down the multiplication of germs.

10. Test container according to claim 1, wherein the container has been subjected to radiation which penetrates into the medium used for disinfection or for sterilisation is conceivable, such as for example UV light or also electron irradiation.

10. Test container according to claim 1, wherein the test container is a plastic container or a glass container.

11. Test container according to claim 1, wherein a further substance is located in the liquid, making it possible to differentiate the container on the basis of a smell of the liquid.

12. Test container according to claim 11, wherein the further substance is selected from a group of substances containing acetone, raw pyridine, crystal violet, fusel oil, isopropyl alcohol, methyl ethyl ketone, methyl isopropylene ketone, ethyl sec-amyl ketone, wood alcohol, rock oil, methanol, thiophene, mixtures of these substances and the like.

13. Test container according to claim 1, wherein several foreign bodies with physical characteristics which differ from one another are disposed in the container.

15. Test container according to claim 1, wherein at least one foreign body is fixed relative to the container.

16. Test container according to claim 1, wherein the test container has an identification element which can be recognised by a machine.

17. Test container according to claim 1, wherein the container has a second closure which closes the container in addition to the first closure.

18. Test container according to claim 17, wherein the second closure is disposed inside a mouth region of the test container.

Description

BRIEF DESCRIPTION

[0025] Some of the embodiments will be described in detail, with reference to the following figures, wherein like designations denote like members, wherein:

[0026] FIG. 1 shows a representation of a container;

[0027] FIG. 2 shows a view of a detail of the container according to FIG. 1, and

[0028] FIG. 3 shows a representation of a wall section of the container.

DETAILED DESCRIPTION

[0029] FIG. 1 shows a schematic representation of a container 1 according to embodiments of the invention. In this case this container has a circumferential main body 2 as well as a base. A liquid 4 is disposed within the container.

[0030] Furthermore the container has a closure 12, such as a screw cap in this case, which closes the container in a liquid-tight manner.

[0031] A deliberately introduced foreign body 8 is located within the container or the liquid respectively. This is illustrated here as circular, but it may also have other geometric configurations. In addition it would also be possible to dispose a further foreign body 8a on an inner wall of the container. In this way those inspection processes which react to defects on or in the wall of the container can also be controlled. In addition defects could also be applied in a targeted manner, for example on the main body of the container, such as for example scratches, material irregularities and the like. It would also be possible for a plurality of different foreign bodies to be disposed in the container, in order to test different characteristics of an inspection machine 20 in a targeted manner. In this case it would be possible for these foreign bodies to react differently to movements of the container, such as for example rotations of the container about its longitudinal axis. These foreign bodies can also be made from different materials.

[0032] FIG. 2 shows a detail view of an upper region of the container 1. In this case it can be seen that the container has a second closure 14 which is disposed in a neck region lb of the container. This second closure means may be a clamping member which, as is indicated in FIG. 2, expands in the direction of the mouth or the inner wall of the mouth respectively and thus likewise securely closes the container. The reference numeral 16 identifies quite schematically a transmitting device which for example can transmit a signal which identifies the container 1. In this case it may for example be an RFID tag or the like or in particular a transmitting device which is activated by an external power source. In this way this element can be activated for example in a machine disposed downstream and can transmit a signal by which the test container which has undesirably entered the output stream of containers is separated out again.

[0033] FIG. 3 shows a detail of the main body 2 or the wall region thereof respectively. It will be recognised that here an element 18 is introduced in the wall. As mentioned above, this element can in turn serve for testing inspection devices. In addition, however, this element 18 may also be an information carrier which for example has a marking or by means of which a marking or an information can be read respectively which unambiguously identifies the test container.

[0034] Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.

[0035] For the sake of clarity, it is to be understood that the use of a or an throughout this application does not exclude a plurality, and comprising does not exclude other steps or elements. The mention of a unit or a module does not preclude the use of more than one unit or module.
