Description

Pressure cell for dispensing multicomponent substance contained therein

Technical area

The present invention relates to a pressure cell for discharging multicomponent substance contained therein, in particular a multicomponent substance for forming a hardening layer when coating a substrate, according to the preamble of patent claim 1.

State of the art

A pressure cell of the aforementioned type is known for example from WO-85/00157 and partly also from WO-02/076852. This known pressure box is formed as an elongated container with a arranged at a discharge-side end thereof dome and .A arranged at the other end thereof bottom. On Dom is, coaxial with the container, arranged a valve for discharging the multi-component substance. Within the container and coaxially with the axis thereof is disposed an elongated inner sleeve which is secured at one end thereof to the bottom and sealed thereto, while the other end of the inner sleeve is exposed within the container and sealed by a cover which can be deflashed by the inner sleeve , Coaxially to the container, an elongate plunger is arranged, of which there is an inner-side longitudinal section inside the inner sleeve and an outer longitudinal section outside the container. The plunger goes through the floor at a transition point between said lengths and is there on the one hand sealed against the ground and thus relative to the container, on the other hand on the ground and thus rotatable relative to the container but not axially displaceable.

In a state of the art publicly documented in brochures (for example, in brochures concerning pressurized cans for "Nano-Fix 200", available from Atheco AG, CH-7000 Chur, or for "Samicolor® Nanobois", available from Kälin & Co. AG , CH-8404 Winterthur), the plunger is provided at least on a part of its inner-side longitudinal portion with an external thread, with a corresponding internal thread of a bore of a relative to the inner sleeve displaceable threaded nut part cooperates to axially displace the Gewindemutterteil upon rotation of the plunger and to remove the latter by the interaction with the latter of the inner sleeve, wherein an actuating handle for rotating the plunger is mounted coaxially on the outer side longitudinal portion of the plunger. When the cover is removed from the inner sleeve, a component of the substance contained in the inner sleeve can come into contact with a component of the substance contained in the container outside the inner sleeve, whereupon the two components mix with one another in the container and thereby the ready-to-use multicomponent substance ready for dispensing is provided to be applied to the substrate when opening the valve of the pressure cell. Thus, the rotation of the actuating handle relative to the container causes "activation" of the pressure can in the sense that separately present components mix with each other upon activation, thereby providing the ready-to-use multicomponent substance.

As is well known, however, the ready-to-use multicomponent substance in the container of the "activated" pressure cell is only stable for a limited time, its usability deteriorates over time. It is therefore a disadvantage of the aforementioned prior art that the unintentional or willful unauthorized "activation" of the pressure cell can neither be prevented, nor is recognizable at the pressure can - think, for example, playful manipulation of goods on the shelf of a department store.

The object of the invention is therefore to prevent a unintentional "activation" of the pressure cell in a pressure cell of the type mentioned and to make a wanton unauthorized "activation" on the pressure cell recognizable.

Presentation of the invention

To solve this problem, a pressure cell of the type mentioned is characterized according to the invention by the combination of the features specified in claim 1. Advantageous developments of the inventive pressure box are defined in the dependent claims.

In particular, in the inventive pressure box of the actuating handle on the plunger axially between a safety position and a Sliding actuating position. In the safety position, the actuating handle is located at an axial distance from the container, and it is freely rotatable on the plunger. In the actuated position, the actuating handle is in the immediate axial vicinity of the container, and it is rotatably connected to the plunger. Only in the safety position is thus between the operating handle and the container around the plunger around a securing gap. In the inventive pressure box also in the securing gap suitable spacer is provided. This spacer is insertable into the securing gap to prevent displacement of the actuating handle on the plunger from the safety position to the actuation position. To release said shift from the securing gap, the spacer is removable from the securing gap.

From the foregoing it can be seen that the operating handle can not rotate the plunger when the spacer at the pressure box, i. in the safety gap: thus, thanks to the invention, an unintentional "activation" of the inventive pressure cell is prevented.

From the foregoing, it also appears that the spacer is no longer attached to the pressure box, i. in the safety gap is when the plunger was rotated by means of the actuating handle: thus, thanks to the invention, an "activation" made on the pressure box recognizable, regardless of whether it has taken place unconsciously, consciously or even wantonly and without authorization.

Preferably, the spacer comprises a clamp member which, when the spacer is in the safety gap, is clamped tightly to the plunger. As a result, the spacer is detachably attached to the plunger, i. attached to the pressure cell.

If the actuating handle has an axial wall profile which at least in places coincides in the radial direction at least with a wall profile of the container, but otherwise within the Wandungsprofils of the container and nowhere projecting radially from the wall profile of the container, then the spacer located in the securing gap on advantageous Way an axial wall profile, which in the radial viewing direction at least in places with the wall profile of the Container roughly matches. It follows that the spacer located in the securing gap is at least in places approximately flush with the container and the operating handle, which gives the pressure box advantageously a regular representational form, which confectioning example with labels and quite generally the supply of the pressure cell and in particular the installation of the pressure cell on the shelf of a department store easier.

The spacer preferably has a pull-out aid designed as a handle, tab or the like, which facilitates its removal from the securing gap, wherein this pull-out aid can optionally be designed as a flexible tab arranged on the spacer and can be returned to the wall profile of the container by slightest stress.

In a preferred embodiment of the actuating handle, this has around its axis radially arranged radial arms and indentations formed therebetween, in which the spacer located in the securing gap for the fingers of an operator can be reached. This allows the operator to easily remove it from the securing gap by pressing on the spacer. In addition, if it is ensured in a preferred manner that the wall profile of the spacer located in the securing gap nowhere protrudes radially from the wall profile of the container, so here too the pressure box advantageously has a regular representational form, which the packaging, for example, with labels and quite generally supplying the pressure cell and in particular the installation of the pressure cell on the shelf of a department store easier.

Preferably, the actuating handle located in the actuation position is rotatably connected to the plunger by press fitting, which allows a particularly favorable production. In addition, it is preferably ensured that the operating handle by pressing it to the container out at

Overcoming the friction of the press fit is slidable in the operating position, this also leads to a particularly simple operation of the pressure cell in their "activation": you need only the bottom of the

Press in axially, if necessary by striking a suitable hard object. In another preferred embodiment, the operating handle located in the operating position with the plunger by cooperation of at least one survey with a corresponding recess rotatably connected, elevation and depression are mutually arranged on the operating handle and plunger, for example, with the survey as inwardly projecting flattening in an axial bore on the operating handle and with the recess as milled flattening on the plunger. This training ensures the adhesion between the operating handle and the plunger during its rotation particularly well.

In addition, it can be ensured in a preferred manner that the displacement of the actuating handle from the safety position to the actuation position is irreversible: as a significant advantage is achieved in that it is not possible to reverse the recognizability of a willful unauthorized "activation" on the pressure cell. Advantageously, the irreversibility of the displacement of the actuating handle from the safety position to the actuating position is ensured by a press fit between the actuating handle and the plunger.

Ways to carry out the invention

The pressure cell shown in Fig. 1 for discharging therein contained multicomponent substance according to the prior art according to WO-85/00157 is generally denoted by the reference numeral oil. The pressure box Ol has an elongate tubular container 02, whose longitudinal axis is designated A. A discharge side end 03 of the container 02 is provided with a dome 04 disposed thereon. The other, bottom end 05 of the container 02 is provided with a bottom 06 arranged thereon. On Dom 04, coaxial with the container 02, a generally designated 07 valve is arranged, through which the substance contained in the pressure cell oil can be applied. Within the container 02 and coaxially with an elongated tubular inner sleeve 08 is arranged. At its one, bottom axial end 09, the inner sleeve 08 is fixed to the bottom 06 and sealed against this. With its other, dome-axial End 10, the inner sleeve 08 is free within the container 02. The inner sleeve 08 is sealed at its dome-side end 10 by a cover 11, said cover 11 is absprengbar of the inner sleeve 08. Coaxial with the container 02, an elongated plunger 12 is arranged. An inside longitudinal portion 13 of the plunger 12 is located within the inner sleeve 08 and the container 02, and an outer longitudinal portion 14 of the plunger 12 is located outside the inner sleeve 08 and the container 02. At a transition point 15 between its inner longitudinal portion 13 and its outer side longitudinal section 14, the plunger 12 passes through the bottom 06 of the container 02. At this transition point 15, the plunger 12 is sealed against the bottom 06 and thus sealed against the container 02 and rotatably supported on the bottom 06 and thus relative to the container 02 but axially non-displaceable.

Not visible in Fig. 1, but in Fig. 2a and 2b, is the initially mentioned, in brochures publicly documented prior art, according to which the plunger 12 is provided at least on a portion of its inner-side longitudinal portion 13 with an external thread 16, which with a corresponding internal thread 17 of a bore 18 of a displaceable relative to the inner sleeve 08 Gewindemutterteils 19 cooperates, so that upon rotation of the plunger 12, the threaded nut member 19 axially displaces, then in a suitable direction of rotation of the plunger 12, the threaded nut member 19 cooperates with the lid 11 to the lid 11th to remove from the inner sleeve 08 (this interaction results in the present embodiment of training itself from the integral-one-piece Anformung the Gewindemutterteils 19 on the lid 11). For actuation i. for rotation of the plunger 12, an actuating handle 20 is coaxially attached to the outer side longitudinal portion 14 of the plunger 12.

As shown, the operating handle 20 is in its operating position 22 in the immediate axial vicinity of the bottom end 05 of the container 02 (see in Fig. 3), in its safety position 21, however, at an axial distance from the bottom end 05 of the container 02 (see, in Fig. 2a and 2b), being in this safety position 21 between the actuating handle 20 and the bottom end 05 of the container 02, around the plunger around, a Securing gap 23 forms, in which a matching spacer 24 is used, as shown in Fig. 2a and 2b.

When the operating handle 20 is in its safety position 21, but no spacer 24 is in the securing gap 23, the operating handle 20 on the plunger 12 can be moved axially from its safety position 21 to its actuating position 22. The insertion and insertion of a spacer 24 in the securing gap 23 thus prevents the displacement of the actuating handle 20 on the plunger 12 from the safety position 21 to the actuating position 22, while the removal of the inserted spacer 24 from the securing gap 23, the displacement of the actuating handle 20 on the plunger 12 of the Safety position 21 to the operating position 22 releases.

The actuating handle 20 is freely rotatable in its safety position 21 on the plunger 12. This is achieved by a corresponding design of the seat of the operating handle 20 on the plunger 12 in its safety position 21, for example according to a training variant shown in Fig. 2a and 2b, by the operating handle 20 is seated in its safety position 21 with clearance on the plunger 12.

By contrast, the operating handle 20 is rotatably connected in its operating position 22 with the plunger 12. This is achieved by a corresponding design of the seat of the operating handle 20 on the plunger 12 in its operating position 22, for example according to a variant shown in Fig. 3 training variant by the operating handle 20 is seated in its operating position 22 with press fit on the plunger 12.

According to another variant of the training or in addition to the above-mentioned training variant with press fit in the operating position 22 of the actuating handle 20 whose rotatable connection with the plunger 12 by the interaction of at least one elevation 25 rotatably connected to a corresponding recess 26, wherein elevation 25 and recess 26 alternately Operating handle 20 and plunger 12 are arranged. For example, in Fig. 3 on one half of the axial section and much better in Figures 4a, 4b, 5a and 5b, the elevation 25 as inwardly projecting flattening within an axial bore 27 of the actuating handle 20 and the recess 26 as milled Flattening on the plunger 12 recognizable. However, it should be clear that an adhesion of equal quality between the operating handle 20 and the plunger 12 is ensured during its rotation when the elevation 25 on the plunger 12 and the recess 26 are mounted on the actuating handle 20, and even better, if in pairs Accordingly, more than just a survey such as 25 and a recess 26 are provided on each of the plunger 12 and the actuating handle 20.

It is advantageous to provide that the displacement of the actuating handle 20 on the plunger 12 from the safety position 21 to the actuation position 22 is irreversible in order to make the activation of the pressure cell permanently recognizable. A simplest approach is to use the seat of the

Actuating handle 20 on the plunger 12 form an interference fit, so that the displacement of the actuating handle 20 to its operating position 22 can only take place by firmly pressing the operating handle 20 to the container 02 in overcoming the friction of the press fit and the

Actuating handle 20 could be withdrawn only by force in its safety position 21. In addition, the irreversibility of the

Displacement of the actuating handle 20 is promoted from its safety position 21 to its actuating position 22 by the measure described below.

On the plunger 12, a groove 29 is provided near the end of its outer side longitudinal portion 14, which is referred to as an annular recess on the plunger 12 in Figs. 5a and 5b and in Figs. 2a, 2b and 3 can be seen. On the actuating handle 20 is a matching, substantially annular cam 28 is provided which consists in the illustrated embodiment of four integrally formed on the actuating handle ring segments 20 which protrude in the axial bore 27 of the actuating handle 20 inwardly and are all recognizable in Fig. 4a, while in Fig. 4b only two of them are recognizable. This division of the cam 28 in four ring segments gives this, with a corresponding design of the actuating handle 20 of sufficiently elastic material, a certain radial elasticity. In the safety position

21 of the operating handle 20, the cam 28 is engaged in the groove 29. To the operating handle 20 from the safety position 21 to the actuation position

To move 22, ie first at the beginning of the displacement of the cam 28 must be levered out of the groove 29, which is possible thanks to the mentioned elasticity, but provides an axial resistance, the then suddenly diminishes when the cam 28 leaves the groove 29. Thereupon, the axial force of the operator to overcome the mentioned axial resistance suddenly transfers to overcoming the friction of the interference fit in the displacement of the operating handle 20. In such circumstances, a fairly large friction of the press fit can be provided, which in fact the irreversibility of the displacement of the operating handle 20 ensures its safety position 21 to its actuation position 22. Again, it should be clear that the same result is achieved when, conversely, the cam on the plunger 12, for example, as an annular elevation and the groove on the operating handle 20 are mounted as a recess.

3, but also from FIGS. 2 a and 2 b, it can be seen that the actuating handle 20 has an axial wall profile which approximately coincides at least in places with a wall profile of the container 02 in the radial viewing direction, but otherwise within the wall profile of the container 02 lies and nowhere protrudes radially from the wall profile of the container 02.

Preferably, as shown in FIGS. 2 a and 2 b, the spacer 24 located in the securing gap 23 also has an axial wall profile 30 which likewise, at least in places, coincides approximately with the wall profile of the container 02 in the radial viewing direction, so that the in the securing gap 23 located spacers 24 at least in places with the container 02 and the operating handle 20 is approximately flush. It can be provided that the spacer 24, to facilitate his

Removal from the securing gap 23, as a handle, tab or

^{■ has the} same trained pull-out, optionally so that it does not protrude substantially from the wall profile of the container 02 radially, as arranged on the spacer 24 flexible tab may be formed, which is brought back by slightest stress in the wall profile of the container 02.

In a preferred embodiment of a spacer 24 shown in Fig. 2a, 2b, 6 and 7, this is made in one piece of elastic material such as plastic, and it has a clamp member 31, which, when the spacer 24 as in Fig. 2a and 2b shown in the securing gap 23 is seated clamped on the plunger 12. As shown in Figs. 4a, 7 and 8a, the operating handle 20 can be around its

Axis radially arranged radial arms 32 and formed therebetween

Indentations 33 have. In these recesses 33 of the present in the securing gap 23 spacer 24 for the fingers of a

Operator accessible. The operator allows this

Measure to act on the spacer 24 or press to remove the latter from the securing gap 23 or wegzudrücken without for this purpose the wall profile of the spacer used 24 would have to protrude radially from the wall profile of the container 02.

In Fig. 8a and 8b a butterfly-shaped configuration of the spacer 24 'is shown with a central annular socket 34 and two breakaway wings 35 arranged thereon, the axial wall profiles of the (not shown) container, the wings 35 of the distance ha Iters 24' ( with Wandungsprofil 30 ') and the actuating handle 20 and its arms 32 approximately match. In this embodiment it is provided that the spacer 24 'can be broken off at intended break points 36 thereof and on the actuating handle 20 past the plunger 12 and removed therefrom. To activate the pressure cell then the operating handle 20 is to push the plunger 12 until it engages in the operating position.

The wheel-shaped spacer 24 "is mounted on the plunger 12 between the bottom end of the container of the pressure cell and the operating handle, wherein the axial wall profiles of the container (not shown) of the spacer 24 "(with wall profile 30") and the actuating handle 20 and whose arms 32 approximately match. In this embodiment it is provided that both the actuating handle 20 and the spacer 24 "are detachable from the plunger 12. To activate the pressure box, the actuating handle 20 and the spacer 24" are to be removed one after the other from the plunger 12, then the actuating handle 20 (now without the Spacer 24 ") again put on the plunger 12, and finally the operating handle 20 on the plunger 12 to push to the operating position 22.

In Fig. 10 a splint-shaped configuration of the spacer 24 '"is shown, in which an elongated body 37 of the spacer 24''at one end with a head 38 and at the other end with an elastic fork 39 is provided. The pin-shaped spacer 24 '"is inserted with its body 37 in a corresponding diametrical through-hole 40 of the plunger 12 and holds therein by means of the elastic fork 39, wherein the axial wall profiles of the container (not shown), the head 38 of the spacer 24'" (( With this design it is provided that to activate the pressure cell, the spacer 24 with the help of his serving as a handle head 38 from the plunger 12 to remove by pulling away and Thereafter, the actuating handle 20 on the plunger 12 is to be pressed until it engages in the actuation position 22.
