Vsrschiüßvcrrichtun ™ r.ach AnsT '"" h 1 ^u i "4, characterized in that the plate carrier (28) has a cylindrical shaft (37) through the wall or first and second slot (38,39) arranged therein. a first and a second projection element (30, 31), each having the latching step (35) with the latching stop (35 ') and assigned to the lower shell (14) of the housing (12), protrudes.

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

Closing devices are desirable for vacuum jugs in which by a simple latching mechanism that can be actuated for example by means of a push button When the lid is fixed, the pouring channel can be opened or closed. A closure is known according to DE-GM 83 35 012, in which the "ballpoint pen principle" is used for the locking mechanism There are projections on the outside of an inner sleeve element and inclined surfaces on its lower edge integrally formed in order to exert a laterally acting force on the sliding element when this one is perpendicular is subject to acting force. The sliding element in turn is provided with projections that be retained by the top edge of the inner sleeve member or retaining projections can to achieve a lower position and an upper position, the position change through Depression of an associated spring element is carried out.

With such closure devices provided cans have the disadvantage that the inclined surfaces must always maintain a certain angle of inclination on the sleeve element, so that between the two Parts of the locking mechanism (crown and sole) on which the projections are in the upper and lower position come to rest only a comparatively small distance and the sealing plate only a small distance Releases opening gap. Another disadvantage is that by abrasion and wear of the rubbing Parts of the function is impaired after a certain period of time.

The invention is based on the object of a new, improved locking device with a latching mechanism indicate which is a comparatively long distance between the closing and opening points of the Sealing plate allows. Wear of the locking elements should be minimized in order to impair their function to avoid even with prolonged use and to reduce the availability of the locking device

This object is achieved by a closure device according to the characterizing part of the present claim 1 solved.

In the case of the present invention, there are thus two locking positions which, with the appropriate dimensions the housing of the locking device can be pulled apart comparatively far. Through the

adjustable pawl carrier results in a completely new type of lock in which the parts are generally less susceptible to wear are and in which a relatively large opening path can be maintained. The latter is between the stop of the sealing plate and asm the stop of the pawl carrier on the latching step. More, for that Invention essential features, which are found in the subclaims, are in the following description an exemplary embodiment explained with reference to a drawing. The figures in the drawing show in individual:

Fi g. 1 shows a section through the top of a jug with a closure device according to the invention, wherein the cut is made through the lateral channel (Sealing plate closed);

F i g. 2 is a view similar to FIG. 1, but with a cut offset by 90 °;

F i g. 3 and F i g. 4 show sectional views similar to W12 in FIGS. 1 and 2, but in a different position the locking mechanism (sealing plate open).

1 to 4 are sectional side and front views through an upper part 1 of an insulating jug, the neck 9 of which is closed with a closure device 2. Such insulating jugs are known in numerous variations. In the present case, the insulating jug is equipped with an insulating vessel 3, a so-called dewar, which is built into a protective container 4. Outside the inner edge 5, the protective container 4 is designed with a collar 6, which is shaped into a closed pouring spout 7 with an outflow channel T on one side. A handle 11 is provided on the side opposite the pouring spout 7. The collar 6, sloping inwardly towards the edge 5, forms the neck 9, which has an internal thread 10 on at least part of its inner circumferential surface. The closure device 2 is screwed into the thread in such a way that it seals and closes the neck 9

The locking device can, however, also be attached to a folding arm with the omission of a thread which is hinged to the handle 8. Such embodiments are also known and with a to equip corresponding locking device according to the invention.

The locking device 2, the interior of which results from the two sectional views offset by 90 °, is composed of several parts. The exterior of the closure device forms a housing 12, which is in turn composed of an upper shell 13 and a lower shell 14 to 15. Both shells 13 and 14 have an approximately dome-shaped appearance.

In the upper shell 13 is a centric with a pulled down, free-ending, cylindrical wall 19 provided central opening 16 let in, in which a vertically movable push button 17 is guided and held. The push button 17 is with a flange 18 on the pulled down wall 19 so far that its upward movement is limited. Center opening 16 and push button 17 represent cylindrical structures.

Bead 24 in turn rests sealingly on the inner edge 5 of the protective container 4 and so for a seal cares

A channel 25 surrounded by walls within the lower shell 14 extends laterally from the opening 21 and, when the closure device is screwed in, comes to lie in alignment with the outflow channel T of the pouring spout 7. Through the opening 21 and the channels 25 and T there is a continuous path given for the liquid coming out of the vessel 3.

This path can be opened and closed by a sealing plate 27, which with its edges 27 ' presses against the seal seat 22 from below in the sealing state. The seal plate 27 is part a plate carrier 28, which is of particular importance for the function of the locking mechanism mentioned above Importance is

A cylindrical section located above the sealing plate 27 is denoted by 29. He is following above in two spring tongues 26, which together act as a braking element for a KJinkträger described below 40 serve.

Above the opening of the cylindrical section 29, the plate carrier 28 expands to form a guide sleeve 33. The guide sleeve 33 is vertically movably guided within an inner jacket 34, which is part of the Lower shell 14 struts upwards from the edges of the opening 21. The inner jacket 34 is at the point the channel 25 branches off, open, otherwise closed. To prevent liquid when pouring penetrates into the locking mechanism, a rolling ring seal 32 is between the plate carrier 28, namely in the guide sleeve 33 and the lower shell 14 of the housing 12 are used.

The inner jacket 34 carries two opposite one another, starting from its inner edges and projecting inwardly first and second projection elements 30 and 31. The (31) of the elements is provided with a latching step 35 provided, as shown in FIG. 2 shows. This results in a stop 35 'at a certain height. At the In the area of the first and second projection elements 30 and 31, the plate carrier 28 is a shaft 37 with partial formed changed diameter, in the wall two opposite first and second Slots 38, 39 are embedded through which the Z-shaped first and second projection elements 30, 31 protrude.

Furthermore, a vertically adjustable pawl carrier 40 is attached to a rotation axis 41, which in its first Position (F i g. 2) to the left and in its second position (F i g. 4) is inclined to the right and thereby against the stop 35 'strikes from below. The axis of rotation 41 is rotatably embedded in the guide sleeve 33 and allows the pawl carrier 40 to oscillate. In addition, the pawl carrier 40 moves together with the plate carrier 28 up and down.

The pawl carrier 40 has an approximately crest-shaped appearance in cross section. At its top it points a recess 44 delimited by two pawls 42 and 43 into which a pendulum pusher 45 engages. With the pendulum handle 45, the one with a bell 53 via an axis

essential cylindrical outside with an external thread 20 is provided, has a relatively large opening 21 on its underside, which is formed by an annular Seal seat 22 is surrounded. The seal seat 22 is formed from a portion of an H-shaped cross-section Rubber ring seal 23 is formed, the recessed

The underside of the pawl carrier 40 is rounded and lies frictionally wiping the spring tongues 26, which accordingly act as a braking element between the plate carrier 28 and the pawl carrier.

ger 40 work. The pawl carrier 40 is therefore pendulum-braked stored.

The pendulum pusher 45 is also suspended in a pendulum fashion on an axle 46, with arms splayed to the side 47, 47 ', which bear against the bell 53, generate a restoring torque in each case in the central position. The pendulum pusher 45 is made of plastic and has an internal elasticity. Its foot is provided with two ribs 49, which run in the extension of the axis 46. These ribs 49 can each be pressed in two in a compatible manner of three grooves 50 which are formed in the trough 44 with the same extent. This is due to the deflectability of the pendulum pusher 45, the foot of the pendulum pusher 45 is pushed into that of the grooves 50, the adjacent pawl 42 or 43 is in the upper position. This pawl becomes accordingly when going down the pendulum pusher 45, as will be explained further below, pressed down, so that the pawl carrier 40 oscillates from one position to the other. The pendulum pusher 45 has within predetermined elongated holes 56, 56 'of the shaft 37 from the plate carrier 28 a certain vertical play, so that the Pendulum pusher 45 is movable with respect to the pawl carrier 40.

The plate carrier 28 is given a defined closed position with respect to the housing 12 by a spiral spring 52 surrounding it in the region of the shaft 37. This Coil spring 52 presses upwards against the bell 53 on the underside of the push button (flange 18). Downward presses the spiral spring 52 on the lower shell 14 of the housing 12. Since the bell 53, as shown in FIG. 2 shows is let into a head 54 of the plate carrier 28 with play, this is when the pawl 43 is disengaged pulled up. The movement stops when the sealing plate 27 rests against the sealing seat 22.

An upper wall 55 of the push button 17 closes flush with the card-shaped outside in this position the upper shell 13.

The function of the locking device is explained below.

In Fig. 2, the pawl 42 only rubs against the smooth one Inner wall of the projection element 30. When you press the push button 17, the coil spring 52 is on the Bell 53 compressed and the plate carrier 28 shifted downwards. At the same time it becomes rigid with the bell 53 connected axis 46 with the pendulum pusher 45 moved down until the ribs 49 in the Press in the grooves 50 belonging to the pawl 43. The pawl carrier 40 experiences a slight torque right (in Fig. 2). The plate carrier 28 is pressed down at the same time. The pawl 43 moves against the stop 35 'until the sealing plate 27 is in the open position according to FIG. 3/4 is reached When releasing the Push button 17 moves the spring 52 the plate carrier upwards until the pawl 43 is below the stop 35 'stops and remains there. The pendulum pusher 45 continues upwards and leaves with its ribs 49 the Grooves 50 again.

The next time the push button 17 is pressed down, the same ribs 49 snap into the grooves on the left 50 (see Fig. 2/4), which belong to the pawl 42 and push the pawl 43 out of its locking position by pivoting of the pawl carrier 40 out. The plate carrier 40 can thus move within the inner jacket 34 slide at the top until the sealing plate 27 strikes the sealing seat 22 from below. The sealing plate 27 ensures now for a sealing of the opening 21. In the open state of the opening 21, the liquid can from the Vessel can be poured through channel 25-7 ', while in the closed state no pouring is possible is possible. The opening and closing is made possible by actuating the push button 17, the adjustable pawl carrier 40 in the open position against the lower stop 35 'and between the locking steps lets the plate rack remain overall in the position thus defined.

The terms "vertical" and "right" and "left" used in the above description relate on the in the F i g. 2 and 4 shown position of use. Of course, you set the usage locations and construction options are not fixed.
