Abstract

A spout (2) for a petrol container (1) is provided at one end (3) with a double socket (4) permitting the spout (2) to be connected with the container (1) either in a pouring position in which it projects from the container or in a storage position in which it is reversed and located inside the container, the spout (2) having a non-return valve (8) in which a closure member (9) is buoyant to close the spout (2) when in its storage position, but when in the pouring position, allows petrol to flow through the spout (2). The spout (2) and thus container (1) are closable at the socket (4) by a cap (5). <IMAGE>

Description

SPECIFICATION Pouring pipes or spouts for petrol cans or other liquid containers The present invention relates to pouring spouts or pipes for petrol cans or similar liquid containers, the spout or pipe being provided at one end with a fitting which permits the spout or pipe to be connected to the container in a pouring position, in which it projects from the container to facilitate the pouring of liquid from the container, and in a storage position in which it projects into the container and the container can be closed by a cap applied to the fitting.

According to this invention such a spout is provided with a non-return valve which is adapted, in use, under the influence of liquid in the container to close the spout or pipe when the spout or pipe is in its storage position but is adapted, when the spout or pipe is in its pouring position, to allow liquid to flow through the spout or pipe from the container.

With this arrangement it is possible efficiently to eliminate the petrol spurt from the can which was previously sometimes produced on opening of the cap, due to the vapour pressure prevailing in the can.

The invention will be described more fully hereinafter with reference to the accompanying drawings which show, by way of example, two embodiments of the pouring spout in accordance with the invention and in which: Figure 1 is a partly sectional side view of one embodiment of the pouring spout; Figure 2 is a partly sectional side view of the second embodiment of the pouring spout; and Figure 3 shows part of a petrol can provided with the first embodiment of the spout illustrated in Fig. 1, the spout being in its storage position.

A can intended for holding petrol or other liquid is designated by 1. To facilitate pouring out of its contents it is provided with a pouring pipe or spout 2. The pipe 2 is provided at one end 3 with a double socket 4 by means of which the pipe 2 can be connected to the can 1 either in such a way that it projects there from and thus serves as a pouring spout or in such a way that the pipe 2 is located in a storage position inside the can.

The latter position is shown in Fig. 3. In this position the pipe 2 and thus also the can 1 are closable by means of a cap 5 which is screwed into the socket 4. The socket 4 is screwed on to a screw threaded neck 6 on the can 1 and the socket 4 seals against the neck 6 by means of a sealing ring 7.

The pipe 2 is provided with a non-return valve 8 which is adapted under the influence of the liquid in the can 1 to close the pipe 2 when the pipe 2 is in its storage position inside the can 1 but is adapted, in the pouring position of the pipe 2 outside the can 1, to allow the passage of liquid through the pipe 2 from the can 1. The non-return valve 8 is located at the end of the pipe 2 remote from the socket 4.

In the illustrated, preferred embodiments the non-return valve 8 consists of a valve body in which a closure member 9 is displaceable between an inner position 10 and an outer position 11. The inner position is determined by a valve seat against which the valve closure member 9 seals when bearing against it, while the outer position 11 is determined by shoulders or the like so arranged that liquid can pass through the pipe 2 when the valve closure member 9 bears against them.

The valve closure member 9 consists of a ball of plastics or other light-weight material which is buoyant in the liquid in the can 1.

According to the two embodiments shown, the pipe consists of concerntina-like plastics or like flexible and resilient material. In this case it is preferable to allow the concertina fold closest to the valve body to constitute the seat 10 of the valve 8, as is best shown in Fig. 2.

In the embodiment of Figs. 1 and 3 the valve housing is a separate part 1 2 connected to the outermost fold 10 of the pipe 2, which again forms the seat of the valve.

The shoulders 11, which define the outer position of the valve closure member 9, should hinder as little as possible the liquid during pouring. The shoulders therefore have a small circumferential extent. Moreover, the shoulders 11, which preferably are only three in number, have their tips on a circle the diameter of which is only slightly smaller than the diameter of the closure member 9 which is a ball. This makes it easy to press the valve closure member formed by the ball into position in the valve body.
