Containers for liquids.

The invention relates to a container for liquids which is provided with a pouring device.

Containers for liquids are known which have only a single opening through which, when the container is emptied, the liquid flows out and the compensating air flows in at the same time. a These flow conditions lead to the disadvantage that the outflowing liquid has a turbulent flow that leaves the container in the form of jerky and intermittent jets and results in undesirable splashes of liquid droplets.

In order to remedy this disadvantage, it has already been proposed in the vicinity of the pouring opening, for example in the area a neck of the container to open an auxiliary line that does not carry any liquid and only for air access is determined. This line is through one of its ends in connection with the top of the container, which the Contains liquid,

The present invention is directed to containers of this type and allows for equipment with a pouring device, wherein it is preferably a container that is made from a plastic drop by the blow molding process and in which an inner partition can only be formed by squeezing the walls. It is advantageous if the handle of the Container serves as a ventilation pipe or as a pipe for the passage of the compensating air.

The invention has a container of this type with a neck for pouring the object in which an auxiliary line for the Passage of the air opens, which is in connection with the upper part of the container *. Such a container is marked s: h according to the invention in that the pouring device, the alch is located inside the neck of the container, a line is formed, the cross-section of which is smaller than the line cross-section of the Neck, and by means of a portion that cooperates with a seat on the inner wall of the neck, sealingly in the Neck can be clamped into which the above-mentioned auxiliary line opens.

The arranged in the interior of the neck of the pouring device is for a basic feature of the present invention, a line which makes it possible to guide the liquid when pouring through the neck in a respect to the neck cross-section smaller w cable cross-section, wherein the region of the neck, the outside this line remains free for the passage of air.

According to a further feature of the invention, the pouring device both rigidly connected to the container or detachably connected to the interior of the neck.

The invention can be used in various ways. BeeoMers advantageous embodiments according to the invention are given in detail below.

In a first preferred embodiment according to the invention, the line of the AuegieSvorrichtung is at its lower end

Selects opening, this should be the mouth of the air duct immediately are opposite when the pouring device is being prepared for use. After an advantageous modification This embodiment of the invention opens the air line in a HdäLraum which is formed in the interior of the neck and the surrounds the entire circumferential surface of the cuff in such a way that also in the event that only a single lateral opening is used, this is inevitably in connection with the air line of the container.

In all embodiments, the dimensions of the spout The device is preferably chosen so that the liquid line touches the upper hand of the neck after the pouring device has been inserted towers above in order to avoid that the liquid jet when emptying the container possibly with the opening of the neck comes into contact.

If, on the other hand, one chooses an embodiment according to the invention in which a shaft and a sleeve is used, it is advantageous when the sleeve has such dimensions in the application that it is not level with the neck but that the upper part of the sleeve, on the contrary, is arranged below the upper opening of the neck in order to achieve that the neck can be closed with a conventional lid which bears ridges or lips covering the walls of the neck pinch.

The pouring device according to the invention is advantageous made from one piece, namely from a synthetic one Shaped material, which is the same material from which the container is made.

The invention is explained below with the aid of several exemplary embodiments explained with reference to the drawings. In the drawings show:

The containers shown in the drawings are different embodiments of a canister or tank known per se, which has a part 1 forming a handle on its upper part, in which a line two is provided, which at one of its ends with a cavity 3 of the container in connection and the other end into the interior a neck 4 of the container opens.

In the in Pig. In the embodiment shown in FIG. 1, a line of a pouring device in accordance with the features of the invention is inserted into the interior of the neck 4. This i Ausgießleitung has the shape of a shaft 5, which is provided at its lower end with a bulge 6, whose outer surface closely to a surface 7 creates a seat which is formed at the lower end of the neck 4 of the container.

Pur the pail, that the canister and the pouring device from Plastic are made, the bead 6 can as well as the seat 7 easily during the process of the canister or form the pouring device.

It can be seen that when the container is pivoted to pour out the liquid contained therein, it passes through the shaft 5 flows and the compensating air can continuously penetrate via line 2 into the container without the air flowing out with the liquid comes into contact.

Spacers can be used between the shaft 5 and the wall of the neck 4 8 and 9, for example in an arrangement of four pieces, can be provided in order to make the shaft easier to attach to the one assigned to it Able to bring and hold there. The spacers can either be attached or molded onto the shaft itself or, in other applications, on the neck.

It can also be noted that the shaft 5 protrudes outwardly with respect to the neck 4 in order to avoid that during pouring the resulting jet reaches the opening edge of the neck.

It should also be noted that this version is form according to the invention also allows the use of an internally threaded cover 10 of conventional type, the inner bulges of which 11 pinch the upper portion of the neck 4.

In the Pig. 2, in which the already described Parts are provided with the same reference numbers as in Fig. 1, the pouring device is through a telescopic Line 12 is formed, which comprises two sections 12a and 12b with different cross-sections, which are defined by a surface 13 are connected to one another, which is supported on a seat 14 provided at the lower end of the neck 4. The one with one Section 12b with a smaller cross-section penetrates into the interior of the container and is slidably disposed opposite a corresponding part 15 of the container.

If you want to pour out the liquid contained in the canister, it is sufficient to remove the section 12a of the line 12 from the neck to facilitate the outflow of the liquid and its transfer. It is advantageous if a bead 16 is provided at the lower end of the displaceable section 12b to avoid unintentional full pulling out of the line from the To prevent pouring device. In the event that this or the canister is made of a semi-rigid plastic material is, an intentional pulling apart of the assembled components of the pouring device by the Bead 16 does not significantly interfere when a tensile force is exerted sufficient to deform the plastic material.

It can be seen that in this embodiment, the Container part is at the same level as the upper part of the neck when it is closed by a lid. This arrangement makes it easier to stack the canisters.

In the embodiment shown in FIGS. 3 to 5, there is a bulge or a cavity on the lower part of the neck 4 4a is provided, which runs all around the neck and into which the line 2 opens. This cavity can be found in the course of the Form the molding process of the canister by providing a bead on the neck wall. The pouring device comprises a substantially cylindrical shaft 17 and a coaxially arranged opposite this sleeve 18, which has a bead-shaped Forms continuation of the shaft at its lower end. The outer diameter of the sleeve 18 corresponds essentially to the inner one Diameter of the neck 4 so that the sleeve can be inserted into the neck with a tight fit. The sleeve 18 is supported with a Paragraph 19 on a seat 20 which is provided in the neck 4. In addition, the sleeve 18 is under training at the level of the cavity 4a pierced by holes 21 which establish a connection between the line 2 and the annular space, the between the sleeve 18 and the central shaft 15? educated is. This opens directly into the tree 3 "in which the liquid is contained" and serves as a guide when pouring out the Liquid, while the air penetrates through the annular space into the interior of the canister, which the shaft 17 separates from the sleeve 18, the air passage through the Holes 21 takes place, which are with the cavity 4 a and the line 2 in connection. The latter is consequently of the Shaft 17 completely separated and sealed against these, so that the flow of the liquid does not pass through the access is disturbed by air and no turbulent flow of liquid can be caused. This embodiment has the further Advantage that the sleeve 18 separates the penetration and the accumulation of liquid in the shaft 17 from the neck 4 Gaps partially avoided or delayed when liquid penetrates from the interior of the container via line 2, if the container is accidentally overturned or otherwise carelessly handled.
