DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is directed to a device for ventilating a container for liquids or liquid container which is formed by a removable ventilation device projecting into the container and having line portions of an air line which are angled in the outlet region of the filling opening or emptying opening.
2. Description of the Related Art
Devices of this type are used, for example, in liquid containers for transporting, storing, and making available operating media of all kinds such as fuels, oils or the like, foodstuffs, additives, etc. In particular, repair and maintenance operations for vehicles, machine tools and machinery, machine shops, construction firms and manufacturing operations in the metalworking industry deal with the handling of such liquids.
The devices mentioned above are used, at the same time, for moderately apportioned distribution of liquid held in a container into other containers, e.g., those having a relatively narrow inlet, such as cans, housings or the like.
Liquid containers which are filled up to the filling and emptying neck prevent a laminar flow of liquid out of a container as long as air from the atmosphere is not allowed to enter the hollow interior of the container. At least at first, i.e., until that time when sufficient air can flow into the container via the filling and emptying neck, the liquid flows out in an uncontrollable manner or a time-consuming emptying process takes place accompanied by loss of liquid and/or cleaning work results in the affected surrounding area subsequently.
In order to counter these circumstances, manufacturers of liquid containers or cans have arranged a ventilating line inside the filling and emptying opening forming a connection between the atmosphere and the container space.
For example, CH-A-537308 discloses a liquid container in which at least one holding strip which is formed out in a protruding manner is provided at the inner side of the filling and emptying neck for receiving the ventilation line by means of a holding slot of complementary design such that the ventilation line can be pushed onto the holding strip.
In contrast to a fixed arrangement of the ventilation line, the ventilation line can be removed to fully expose the filling and emptying neck so as to improve access to the container space.
Nevertheless, with the ventilation line disclosed in the cited reference, which has an angled shape in the outlet region of the container, turbulence or unevenness in the liquid flowing out at the filling and emptying opening can also be prevented only after a quantity of liquid has been removed from the full container, because the short ventilation line does not allow any air into the container as long as the end projecting into the container space is located below the surface of the liquid. Also, when containers are partly empty, the air contained therein is not sufficient to prevent uneven emptying.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide a device of the type mentioned above which enables a liquid container or can in the filled state to be ventilated as it is being emptied so that a measured, laminar flowing out of liquid can take place.
This object is met in accordance with the invention in that the line portion of the ventilation device adjoining the line portion communicating with the surroundings extends in a region of the container located farther away from the filling and emptying opening under the upper wall of the container. As a result of this technical step, it is possible when emptying the container for air in the surrounding atmosphere to enter this container, especially in the small hollow space first formed in the upper container region by the initial tilting of the liquid container, and for air to flow in from the surroundings.
The vacuum created in the container when the liquid flows out can be compensated by the suction effect occurring in the surroundings via the line portions by the supply of air to the container regio
