Abstract

An insulating jug having a protective housing is formed of a molded construction of synthetic material and includes an integrally formed spout, which is closed or pipe-shaped and has a conical cross-section that diverges inwardly. A recess is formed in the top of the protective housing to receive a lid element that is threaded on its lower portion and by inserting the threaded portion into a mating threaded portion in the top of the protective housing respective sealing surfaces are brought into contact, and the top of the lid resides within the recess and blocks the spout. Pouring is accomplished by use of relieved portions on the threaded part of the lid, which when unthreaded appropriately permit liquid to exit a container arranged within the molded protective housing.

Claims

1. An insulating jug comprising a protective housing having an injection molded construction of synthetic material and an insulating container inserted therein, said insulating container being held between a floor member and a shoulder in an upper region of said protective housing, an opening of the insulating jug being arranged in said shoulder, an open annular recessed area being formed above said opening and shoulder in said protective housing, said open annular recessed area being dimensioned larger than said opening and adapted to receive a lid for attachment by complementary threads provided on said lid and on said shoulder of the protective housing, and a laterally projecting spout commencing at said open annular recessed area, and characterized in that said spout is of pipe-shaped cross-section and is conically enlarged inwardly, said spout being integrally formed with said injection molded-construction, synthetic-material protective housing, and an annular flange is arranged at an inner edge of said shoulder and projecting into the opening of the insulating container and having one of said complementary threads formed as an internal thread thereon, and said lid has on a lower side a projection having the other of said complementary threads formed as an external thread thereon for engagement with the internal thread of said annular flange, said lid having a shoulder above said projection with a sealing surface that cooperates with an upper surface of said annular flange of said shoulder, so that in a first lid position said sealing surface of said lid and said upper surface form a seal and in a second lid position axially spaced apart from said first position and having said threads engaged, said sealing surface is spaced apart from said upper surface, whereby liquid can be poured from said container.

2. A jug according to claim 1, characterized in that on the lid there is provided a marking which indicates by it'"'"'s rotational position relative to the housing when the lid is in the pouring position.

3. A jug according to claim 1, characterized in that the jug has a handle which is integral with the housing and which lies diametrically opposite the spout.

4. A jug according to claim 1, in which in said annular flange at least one axially extending flattened area is provided arranged on that side of the annular flange that faces the spout when the lid is in a pouring position.

5. A jug according to claim 1, further comprising a casing surface provided on said lid projection and having at least one axially extending flattened area, said flattened area being so formed to end before said sealing surface of the lid and being arranged on that side of the projection that faces the spout when said lid is in a pouring position.

6. A jug according to claim 5, characterized in that the lid has a pouring position which is displaced in respect of its closed position by a given angle of rotation, more particularly 180°

, and said axially extending flattened area is located on that side of the lid which points toward the spout when the lid is in the pouring position.

7. A jug according to claim 5, characterized in that the lid has a pouring position which is displaced in respect of its closed position by a given angle of rotation, more particularly 180°

, and said axially extending flattened area is located on that side of the lid which points towards the spout when the lid is in the pouring position and further comprising a second flattened area diametrically opposite said at least one flattened area for venting the jug in said pouring position.
