Vessel, in particular vacuum jug or flask

The invention relates to a vessel according to the preamble of claim 1.

Vessels of this type are known and are used every day, for example as vacuum jugs or bottles, vessels with measuring beakers for dry and .Q liquid substances and the like.

The closure members of the known vessels are arranged or dimensioned so that they are used for the purpose of closure or opened manually. As a result, a closure member is given the one with the Hand immediately grabbing handle and therefore not only built relatively large, but also used a correspondingly large amount of material.

The invention is based on the object of providing a vessel 20

of the present genus so that a smaller size is possible and the closure member is none Handling required.

This object is achieved by the characterizing part of claim 1.

In an embodiment according to the invention, this requires Closing member does not have a handle that can be directly grasped by hand because it closes with the help of the cap

bar or can be opened. It can therefore be made smaller be, whereby material can be saved and the size can be reduced. The latter is for vacuum jugs or bottles therefore of particular advantage,

because they are items that are used as supply 35

containers are packed in bags or the like and therefore with the largest possible capacity

• · I ■

assets should be as small as possible.

In addition, the configuration according to the invention enables

_ a relatively large power transmission because one b

Cap offers a large contact surface for the hand.

The training according to claim 2 is advantageous because it has a thin-walled construction and therefore allows inexpensive hollow body, which is particularly important for plastic parts.

In an embodiment according to claim 3, the form-fitting surfaces engage in one another in the form of a sleeve, namely

Closing over the entire surface, so that the cap is not only in the 15th

the attached position is held sufficiently, but also the cavity of the cap against contamination is sealed from the outside.

If the form-fitting surfaces according to claim 4 a rule 20th

Form a moderate polygon, there are possibilities in that Number of corners to. assemble the cap and the closure member. The latter is in. Compared to only. one possibility, of course, much more user-friendly.

The further embodiment according to claim 5, the size of the vessel can be further reduced because the Closure member in the vessel uri the cap can be sunk in the closure member.

By training according to claim 6, the grip the cap so that a relatively high torque is exerted with little effort

can be.
35

The design according to claim 7 or 8 improves the retention of the cap in its joined with the closure member Position.

An exemplary embodiment of the invention is described below with the aid of a drawing.

Show it

1 shows an insulating jug in a partially vertical cross-section;

2 shows a plan view of the vacuum jug without a cap; 3 shows a cap in a vertical half-section.

10

The generally designated 1 jug comprises a protective casing 2 with integrally molded-caster and handle 4, disposed in the protective housing 2 insulated container 5, an a filling opening 6 capping ° bares closure member 7 in the form of a threaded plug with a thread 8 and a cup-shaped cap 9 is inserted in an upper-side recess 11 of the closure member 7. The cap is in this position

[<floor 12 above.

20th

The outer peripheral surface 13 of the cap 9 and the inner peripheral surface 14 of the closure member 7 form regular polygons, the edges of which are in positive-locking surfaces 15 which are transverse to the direction of rotation 16 of the cap 9 extend and thus represent a rotational drive between the cap 9 and the closure member 7. The closure member 7 itself is almost completely sunk into the protective housing 2.

Di _e form-locking surfaces 15 extend over the entire lateral surface 17 of the cap 9. The in the fitted position of the closure member 7 projecting part of the cap 9, the hand not shown, can an operator conveniently and easily grasp and exert a torque in the rotational direction of the cap .

To release or close the closure member, the cap 9 is put on or inserted and in the direction of rotation turned. The interlocking surfaces 15 come into mutual abutment, so that the closure member 7 in Direction of rotation 16 is taken.

If the cap 9 is to serve as a drinking vessel, it must be pulled out of the closure member 7.

So that the cap 9 sits with a certain degree of adhesion in the recess 11, this is at least in the area of yours The reason is so tight, or a latching (18) is provided that a certain force is required to move the

Pull the cap out of the recess 11. Through this 15th

this prevents the cap from falling out unintentionally.

The latching 18 can be formed by small knobs 19 on the cap edge 20, which are preferably annular Border free cut 21.

The embodiment described above comprises a screw plug as a closure member. Within the scope of the invention it is also possible to use other plugs, 25

perform the rotary movements when closing or opening, For example, stoppers that can be fixed in the form of bayonet locks.
