RECEPTACLE WITH SCREW CAP

Abstract: By a receptacle (1) in which the pressure can be changed by squeezing for the dosing through a nozzle outlet (2) of the contains, and in which the nozzle outlet can be closed by a screw cap (3), the interior of the receptacle is connected with the nozzle opening via a compressible tube (4) leading through the nozzle. The nozzle has two slots passing through the opening and situated opposite each other. On the two nozzle walls (5) separated by the slots are found two projections facing each other (6). When the screw cap (3) is affixed in such a manner that the slots are squeezed together, the projections (6) will exert such pressure on the tube (4) that passage even of liquids of low viscosity is prevented.

Description: RECEPTACLE WITH SCREW CAP. The invention relates to a receptacle e.g. of a tube type of a kind in which the pressure in the interior can be manually changed, preferably by squeezing of the recepacle for the dosing of a contained medium through an outlet nozzle the opening of which can be closed by a screw cap. When the medium in the container is a paste or a slug¬ gish liquid it is generally sufficient to close the receptacle by tightening the screw cap. In case of li¬ quids of low viscosity such as lock lubricators it is, • however, when the cap has been removed and replaced a certain number of times no longer possible to obtain a secure tightening. The object of the invention is to devise a receptacle of the described character in which it will be feasible in a simple and inexpensive way to ensure a tight clo¬ sing when replacing the screw-cap. This is according to the invention achieved in that -the receptacle interior is connected with the nozzle outlet via an elastic resilient tube leading through the nozzle, and that the outlet nozzle is provided with two slots passing from the opening and situated oppo¬ site each other, and that on the two nozzle walls sepa¬ rated by the slots are found two projections facing each other, which when the screw cap is affixed in such a manner that the slots are squeezed together will exert pressure against the tube and thus prevent the passage through the latter. By a suitable choice of tube material and dimensions in connection with the dimensioning of slots and projec¬ tions it will be easy to ensure a safe tightening of the described receptacle when the screw cap is replaced. When the screw cap is removed and pressure is exerted on OMPI the medium in the container, the pressure thus produced in the tube will take the two projections apart, so that the medium contained can flow through the tube. It is according to the invention advantageous that the receptacle can be divided in two parts along the line of the slots, and that the tube constitutes a part of a detachable bag placed in the receptacle. This allows an easy refilling of the receptacle simply by replacement of the bag, which compared to the container as such is inexpensive. Thus the tube may be of such a length that part of the bag will protrude out of the nozzle opening, this part will be closed but intended for cutting off, when the bag is placed in the receptacle. In the following the invention is described in detail with reference to the drawing showing in perspective one half of the upper section of the receptacle. The described receptacle 1 is compressible in such a man¬ ner that a medium contained in the interior can be exau- sted through a nozzle 2. The opening of the nozzle, which can be closed by means of a screw cap 3 is connected with the interior of the receptacle 1 via a resilient tube 4 leading through the nozzle. The nozzle 2 isslotted in axial direction, and on the two nozzle walls separated by opposite situated slots are found projections 6 facing each other. When the screw cap 3 is placed over the nozzle 2 in such a manner that the slots are squeezed together, the two projections 6 will compress the tube 4, and pre¬ vent passage -through the latter. When the cap 3 is removed, and pressure exerted on the medium contained in the receptacle 1, the liquid will flow through the tube 4 as this is distended and squeeze the projections 6 apart. To ensure stability the wall of the receptacle is com¬ paratively thick. By designing the receptacle so that it can be divided in two along the line of the nozzle slots and make the i:ube part of a bag, which is easily inserted detachably in the receptacle 1, it will be achieved that the receptacle can be easily refilled by replacement of the bag. The bags for the purpose can on the other hand be manu¬ factured of a very light material and at a low price. • PI
