"Filler neck"

Priority ? 15 »July 1970, Great Britain»

The invention "relates to a container filling device and in particular on a filler neck that seibat holds while the container with a liquid (ea are also a gas) is filled.

According to the invention, a filler neck for filling Proposed containers with a liquid, which has the following parts:

(a) an outer part with a circumferential seal is equipped for the attachment to the outer surface of a container to be filled, the Diohtung when it is on the said surface is applied, an outer chamber forms, which duroh the outer surface of the container, the seal and the outer rope is enclosed;

1 09884/1374

(b) an opening through the outer part to which a Vacuum line can be connected, whereby if the Seal rests against the outer surface of the container, in the outer chamber a vacuum can be generated, so that the filler neck is pressed against the outer surface of the container;

(c) a hollow inner part carried by the outer part and has a circumferential seal, which with the outer surface of the container around a hole can be brought into abutment in this outer surface; and

(d) a device for introducing the liquid to pull the container through the inner part to the opening in the outer surface of the container.

In a preferred embodiment of the invention Filler neck is when the filler neck against the outer Surface of the container to be filled is pressed, a second chamber that is separated from the outer chamber by a circumferential Seal is separated on the inner part, formed in the outer chamber

For the purpose of simple construction, it is often convenient that the peripheral seal of the outer part and / or of the internal part cylindrical surface disposed around the respective part IATO

In another advantageous embodiment of the inventive Filler neck tapers the seal on the inner part, which with the outer surface of the container in Plant should be brought inside, whereby if the

1 09884/1374

The filler neck is pressed against the outer surface of the container by a vacuum generated in the outer chamber and the liquid is introduced through the inner part into the opening, the circumferential seal around the inner part with the outer surface of the container into an even denser one Plant is forced.

The circumferential seals the inner part wad the external part can be made of any suitable material A be "However, it is preferable to use an elastomer it, ie rubber <-like material to use"

The circumferential seal of the inner part, which can be, for example, a piece of a Gunnni hose, is expediently stretched over an outwardly projecting rib on the inner part, so that the free end of the seal touch the outer surface of the container can ₀ The inner part is preferably arranged in an adjustable manner in the outer part, for example by means of a screw thread ο In cases where the outer surface of the container against which the filler neck is to be placed | is flat, it is preferred that the inner part is positioned so that its seal protrudes slightly over the outer seal _o This ensures that when the filler neck contacts the container, the free end of the inner seal is deformed before the first Chamber is sealed against the outer surface of the container o The advantage of this measure is explained below.

The inner part is sometimes sweeping with a hollow one Extension, for example a pin *, which allows that the filler neck lighter rj.ohtig in relation to

the container can be located. In cases where the sni-filling container is made of a deformable or flexible material, it is preferred that the hollow Localization FortBatÄ with suitable openings, for example Slots, provided in the wall, so that for the In the event that the container walls collapse, the entrance to the hollow porteatz and thus the inner rope does not blocked or closed.

It is often expedient that the inner part of the invention Filler neck »is provided with a recess which has an edge arranged in such a way that the inner circumferential Seal can be sealed while the filler neck is in use ». This gives a useful one Arrangement for achieving an evacuated outer chamber during the use of the filii connector,

According to the invention, a method is also introduced a liquid in a container with the aid of a filler neck carried by a holding part proposed, wherein the container has an opening in a wall, which method is carried out by opening the filler neck brings to the opening, wherein the filler pawl has a sifting means to a sealing connection with the wall to create the hole; that one applies a suction means ^ L to the container wall, which is carried by the holding part is, and a suction is applied to connect the container to the holding part, and that one liquid into the container introduces while the container is connected to the holder "

In this embodiment, the body of the filling nozzle admits from an outer rope 1, at which a loop ends Rubber seal 2 is attached.

Am bayonet attachment 3 »to which a vacuum line (not shown) is connected, is inserted into the outer part 1, so that a vacuum can be created in the Earamer 4, the occurs when the filler neck meets the outer surface 5 of a container is placed in such a way that the circumferential sighting 2 touches the surface 5 «.

A hollow inner part 6 is screwed into the outer rope t and has a conical lip 7 which extends around the circumference of the inner part 6. A short piece of a strong rubber hose 8 is stretched over the rib 7, so that a circumferential sifting 9 is created around the inner part, in such a way that the free end of the hose can be brought into contact with the outer surface 5 of the container, so that a second chamber 10, which is separated from the chamber 4, is created »The free end of the hose 8 is arranged around an opening 11 in the surface 5 of the container _o The inner part 6 preferably also has an extension in the form of a pin 12 which protrudes into the opening 11 to facilitate the localization of the filler neck with respect to the container. The end of the pin 12 preferably has longitudinal slots 13, for the reasons given below »

the surface is printed until the free bath of the seal 9 has deformed to the extent that the seal 2 also comes into contact with the surface 5. The Earner 4 is then evacuated. By creating a vacuum in the chamber 4, the seal 9 is sucked radially outwards away from the opening 11, whereby the seal 9 creates an even better seal o Applying a "jerk to the chamber 10 _1, for example when liquid is pumped into the container has a similar effect »

In some cases it may be desirable to evacuate the container before the tunnel, mn complete filling siohersustellen, especially if the containers have an unfavorable form "in such a case, before filling over the inner part 6 and the bayonet lug 16 a vacuum The inclined seal is less effective when vacuum is applied to the inner part 6; However, this is only of subordinate importance, since a vacuum has already been applied to the chamber 4.

If thin containers made of a relatively flexible material are evacuated, there is a tendency that the opposite sides of the container collapse and touch each other in the area of the opening 11 _o The pin 12 protruding into the container prevents the opposite sides from being compressed. The slots 13 in the end of the pin 12 also prevent the opposite side of the container from wearing the opening in the pin 12. If the container is not evacuated prior to filling, or if there is no risk of the opposing sides of the container collapsing when a vacuum is applied to the interior of the container, then
