Description

i

  The present invention relates generally and essen-

  purpose of a safety or safety shut-off device for a container or tank with

  a closing cap, as well as with a locking device

  rust provided on the container or reservoir, which comprises at least one locking surface which, when the closure cap is mounted, is in engagement with at least latching

  an elastically deformable hook in the radial direction relative to

  to the median axis of the container, which hook is separated

  surface of the locking or locking surface in the

  of the median axis by shifting or moving an auxiliary element

  with a corner or corner surface and coming into

  taken with a biased or corresponding corner of the crozier

  The invention also relates to various applications

  and uses resulting from the implementation of such a

  positive, as well as systems, assemblies, devices, containers,

  equipment and facilities that are provided.

  In a known safety closure device of this type (German Federal Patent 2,541,175) are provided, on the threaded or screwable closure cap, resiliently displaceable or offset hooks whose gripping or engaging parts slide. when screwing on the closing cap, on protrusions or protuberances of the container,

  so that the hooks are moved radially towards the ex-

  Pivoting back to the original or original position when the engaging parts are behind the projections or protuberances This position of the engaging parts of the hooks behind

  projections or protuberances prevent loosening or demon-

  closing cap This loosening or disassembly is possible only when an annular or ring-shaped element, provided on the receptacle and having a biased or outer corner surface, is offset or displaced in the direction of the closure cap, so that the biased or wedge-shaped surface engages behind slanted surfaces or corresponding corner hooks and hooks

  are moved radially outwardly by pivoting.

  In this position of the annular ring member, the closure cap can be unscrewed from the container because the input elements engage the hooks.

  located outside the region of projections or protuberances

buisances of the container.

  This known closure device has the disadvantage that the annular ring member, for unlocking or detaching the hooks of the closure cap, must be moved in the same direction as the closure cap to loosen or detach the closure cap Because of this same direction of movement, there is the risk that an intentional opening of the container will occur, that is to say that the known closure device is

not completely safe or reliable.

  It is the task of the invention to create a device

  safety closure in which the risk of opening

  accidental or fortuitous nature is further reduced.

  For the solution of this problem, a device for

  security closure, of the kind mentioned at the beginning, is

  formed according to the invention so that the part of the hook, engaging with the locking surface, extends radially outwardly from

  the hook and that the auxiliary element consists of a

  hood to relieve or relieve the loss of

  hook between hook and lock surface, is

mobile towards the container.

  In the safety closure device according to the invention, the movement of the auxiliary element, to separate or undo the catch between hook and locking surface, is therefore in the opposite direction to the removal of the closing cap, so that a container opening inadvertently 1 inadvertently or error

  is practically not possible or to be feared.

  Preferably, the cap member is moved toward the container against the counter pressure of at least one spring provided on the closure cap, so that release or disengagement of the cap member, ap: separation between hooks and locking surface, automatically leads to a return of the cap member to its starting position and, thus, to a restoration of the

  hooking catch between hooks and locking surface.

  In a configuration of this type is obtained a particularly simple structure if the cap member consists of a cup-shaped element closed at the outer end of the closure cap and against the inner bottom surface of which applies the spring to which case the spring is preferably formed at the outer end of the cap of

  closure coming from matter with it.

  To maintain the cap member, after the movement towards the container, so after separation from the hooking catch and locking surface, in this position and to be able to remove or detach the closure cap from the container, a protruding handle protruding or radially outwardly protruding projection may be provided on the closure cap, which extends into or through an opening in the cap member, the axial extent of which is greater that the extent

  axial protrusion forming handle or boss

  lant. This projection protruding handle or protruding boss can be used to maintain the relative position of the closure cap and the cap member one by

  to the other, so to allow the removal of the capu-

  closing post-separation of the snap hook

  between brackets and locking surface due to the

  placement or offset of the cap member.

  The invention will be better understood and atresbuts,

  characteristics, details and advantages of it appear

  more clearly on reading the explanatory description which will

  follow with reference to the accompanying schematic drawings given solely by way of non-limiting example illustrating a presently preferred specific embodiment of the invention and in which: Figure 1 shows a partial section through a safety closure device in the closed position, the dispensing or delivery element of the container or reservoir being shown essentially in front view or in elevation; FIG. 2 represents a partial view of the safety closure device according to FIG. 1;

  FIG. 3 shows, according to a corresponding representation

  in Figure 1, the safety closure device in the position for the opening of the container; and FIG. 4 represents, in an elevational view corresponding to FIG. 2, the closure device of FIG.

  Safety in the service position according to Figure 3.

  The safety closure device shown is used for closing a pipette, in particular for glue or adhesive material, including the dispensing element or delivery element 2, which has an outlet pipe 3 in the shape of a nozzle or nozzle. , is pressed or pressed into the cylindrical container 1, so that the annular shoulder, flange, flange or collar 2 'rests on a shoulder, step or corresponding recess of the container 1 On the annular shoulder 2' are formed projections 4 in which are provided orifices 4 'On the dispensing or delivery element 2 is mounted or placed a closure cap which has a cylindrical portion 5 with a guide extension 6 and

  that a shutter piece 7 attached to rods or bars trans-

  versales 8 and which closes the outer end of the outlet pipe 3 On the rear end of the cylindrical portion are formed spring arms or 9 spring

  of material with it while in the connection area

  between the cylindrical portion 5 and the extension of guiding

  6, hooks 10 extend towards the end

  These hooks consist of an elastically deformable material and extend somewhat obliquely or inclined outwardly. At the front end of the hooks, portions are formed.

  latching or engaging 11 which extend radially

  outward and, in the position shown on

  FIG. 1, are placed in engagement with the orifices 4 'of the -

  protrusions 4 penetrating into them and thus prevent from

  remove the closure cap from the container.

  On the closure cap is threaded or fitted a bucket-shaped cap member 15 which has an oblong or elongated opening 17 into which

  projecting protuberance forming a handle or boss

  The spring arms 14 extend in the cylindrical portion 5 of the closure cap and extend radially outwardly. The resilient arms 9 engage against and press against the inner surface of the bottom wall of the cap member 15. so as to move it away from the open end of the closure cap to a position in which the inner end of the opening 17 is applied against the

protrusion 14 (Figure 2).

  At the open end of the cap member 15 is provided a wedge-shaped or wedge-shaped surface 16 which extends obliquely outwardly and towards the hooking or engaging portions 11 of the hooks. 10 Between

  the inner end of the hooks 10 and the hook portion

  11, inclined or wedge-shaped surfaces 12> correspondingly or conjugately inclined> are provided on the hooks. Stop surfaces 13, which are situated in the vicinity of the projections 4, are furthermore provided. on the hooks 10 at a certain spacing distance of these

skewed surfaces 12.

  For the opening of the safety closure device, the cap member 15 is shifted towards the container 1 against the counteracting action of the springs 9, so that its biased surface 16 comes into contact with or engages the biased surfaces. The closure cap can not then be moved axially because the abutment surfaces 13 of the hooks bear against each other.

  As a result of this, the surface skewed 16

  the hooks 10 radially inwardly and bring the hooking or engagement portions 11 of the hooks out of the region of the orifices 4 'by pulling them out of them (FIG. 3). is obviously also offset with respect to the protuberance forming a handle or boss

  protruding 14 and is in the position according to Figure 4.

  To now be able to remove the closing cap of the container, the user maintains the protuberance forming

  handle 14 in the position shown in FIG.

  t 4 at opening 17, that is to say, it maintains the

  hooks in their position pushed radially towards the inside.

  so that they do not prevent or hinder the removal of

closing cap.

  To install or mount the closure cap, the element

  cap is grasped and mounted or placed together with the cap

  closing portion on the container, so that the hooking portions 11 of the hooks 10 come into the area or in the vicinity of the orifices 4 'If the cap member 15 is then released or released, the springs 9 repel the element cap to the outside and the hooking portions 11 of the hooks can move radially outwardly

  to enter the holes 4 '(Figure 1).

  The various parts of the safety closure device, therefore the dispensing or delivery element with the projections 4, the cap member 15 and the closure cap are preferably made of synthetic, plastic or artificial material.
