Description

in 146504

The present invention relates to a container, for example a tube, of the kind in which the pressure in the container can be changed manually, preferably by compressing the container, for discharging a medium in the container through a discharge nozzle, the mouth of which can be closed by means of an outlet. screw cap · If the medium in the container is a paste or heavy liquid, it is usually sufficient to close the container to tighten the screw lid · However, in the case of light flowing liquids, such as locking oil, after the lid has been removed and reapplied several times no longer possible to obtain safe seal ·

The object of the present invention is to provide a container of the kind in which sealing is obtained in a simple and inexpensive manner by applying the screw cap.

This is achieved according to the invention in that the interior of the container communicates with the nozzle orifice via an elastically compressible hose passed through the nozzle, that the discharge nozzle has two diametrically arranged slits extending from the orifice and that two nozzle walls * separated by the nozzles turned lugs which are designed to allow flow through the hose but, when the screw cap is applied so that the slots are squeezed, are pressed against the hose and squeeze it.

When appropriate selection of hose material and dimensions in connection with the sizing of slots and knobs, there is no difficulty in obtaining a safe seal of the designated container when the screw cap is applied · The hair cap is removed and pressure is exerted on the container. medium, the pressure generated in the hose will drive the two knobs apart so that the contents of the container can flow through the hose.

According to the invention it is advantageous that the container can be divided into two parts along the plane of the slots and that the hose is connected to a bag loosely arranged in the container. Hereby the container can be easily refilled, by simply replacing the bag which, when compared to the other container, can is designed very easily. The hose can thereby have a length such that a part protrudes outside the nozzle mouth, which part is closed, but is cut or cut off after the bag is placed in the container.

The invention will now be explained in more detail in connection with the drawing, the only figure of which shows in perspective one half of the upper end of the container.

The container 1 in question is compressible so that a medium in the container can be discharged through a nozzle 2, the nozzle mouth which can be closed by means of a screw cap 3 communicates with the interior of the container 1 via a compressible hose 4 which is passed through the nozzle.

The nozzle 2 is slotted in the axial direction by two diametrically arranged slots. Hereby, two separate nozzle walls 5 are formed, on which are located mutually facing knobs 6, which abut against the hose 4. The hair cap 3 is attached to the nozzle 2, so that the slots are clamped together, the two knobs 6 press the hose 4 so as- together, that passage through it is impeded.

If the cap 3 is removed and pressure is exerted on the medium in the container 1, this will flow through the hose 4 because it is played out and pushes the knobs 6 apart.

r For stability, the wall of the container 1 is relatively thick. By designing the container such that it can be split in two along the plane of the nozzle slots and performing the hose as part of a bag which can be loosely placed in the container 1, it is achieved that the container can be easily refilled by replacing the bag. These bags, on the other hand, can be made of very thin material and are therefore cheap.
