Date Jul. 20, 1995A container having a snapped-in valve adapter is provided according to the invention with the elastic cooperation, upon engagement and disengagement, of an arrow projecting from the tangential plane of the adapter with one of a plurality of recesses disposed on the circumference of the container with the arrowhead in the direction and the opposite direction of the arrow.

Description

The invention relates to a container with a latched Valve adapter according to the preamble of claim 1 (DE-U-92 09 492).

Valve adapters according to the invention are used for opening and closing the one located inside the valve Valve body that can be reached from the outside with the adapter is. In particular, the valve adapter according to the invention with a dispensing tube and a handle Mistake. When operating the handle, e.g. of the Valve body via a valve tube, the so-called Valve stem, open, through which the substrate flows out and so gets into the adapter tube. adapter This type is used mainly on pressure cans hold the substrate together in the adapter tube and selectively to apply when the valve has been opened is. Such adapters often have at the outer end of the Adapter tube a clamp connection for an extension tube that can be plugged on and with it Help the substrate when operating the handle can also be applied specifically if the Exit of the substrate at a greater distance from the Valve must take place. An example of such Applications of the invention are polyurethane foams, which as assembly foams preferably in construction used to seal components.

According to the invention, the adapter and valve are separated manufactured, the adapter with the container, in the substrate is filled, held together until the substrate is to be applied. The happens especially in small containers, which are proportionate contain small amounts of substrate and their Valve and adapter relatively simple have to be. In these and other use cases the invention usually consist of valve and Adapter made of separate plastic parts.

According to the invention, the valve adapter has a latching device on, which serves to connect the adapter with that Containing valve and containing the substrate temporarily connect positively to this way to ensure that the adapter for Is available when the substrate is deployed should. Such locking connections make outer packaging superfluous, which enclose the parts, but to avoid packaging waste are undesirable. The invention Locking device makes it possible Valve adapter to be used several times, if only Subsets of the substrate are consumed and the Reliable valve adapter between several of these processes should be kept ready.

If the invention applies to cans, especially pressure cans, as used for example in polyurethane foams are used, the recess is appropriate attached in the can cap, which so far only serves to cover the valve to prevent an untimely Exclude actuation of the can valve. Such and other containers must be compared because of their Inferiority on fast-working packaging machines to get finished. So far it is are usually automatic filling machines, at their End the capped and ready-labeled Pressure outlet emerges.

So far it has been the practice to do the can cap by hand mostly brought together by workers with the valve adapter and to lock with them. Although the workload for this is comparatively considerable is, the known locking devices do not bring them together by machine, even then not if the can already has the cap on it is.

In particular, this does not succeed with a previously known one Valve adapter (DE-U-92 09 492) with the Latching device with a can cap can be connected. Because here is the cap lid recessed and form the edges of the recess a slide guide that is parallel to the box and its lid runs. The lead serves as Kulissenstein and must therefore from above through the Recess in the can cap inserted into the backdrop become. In a packaging machine that sets a change of direction ahead because first the adapter guided radially over the can cap and then in the backdrop must be inserted axially. Such movements are difficult to achieve and also set ahead that the backdrop with the sliding block is aligned before the sequence of movements occurs. As a result, valve adapters can be used with the known Locking device only by hand with the Can cap are connected.

In practice there is another disadvantage. He is that there are many in self-service stores Buyers not only those with the can cap Want to buy adapters, but also from others Take off caps adapter to pass over multiple adapters to be able to dispose of. With the well-known scenery guide this is easy because the form fit is only radial Direction exists and the adapter from the can cap can be easily solved if it is axially upwards is pushed.

The invention therefore goes another way, the Basic idea is reproduced in claim 1. Further Features of the invention are the subject of the dependent claims.

Since according to the invention the barbed Projection as preferably aligned transversely to the adapter The packaging machine needs an arrow only a radial movement in the direction of the arrow run to the adapter in the recess introduce the one with the tip of the arrow Direction of arrow is brought up to the can cap. As soon as the arrow head reaches the recess, find in the direction of the arrow the movement for tensioning the Locking spring instead, which relaxes after locking is. The invention enables in this way easier handling when locking the adapter and creates the conditions for the replacement the manual work with packaging machines with high Number of bars.

According to the invention, the projection of the adapter no longer aligned with a specific recess be there before the locking takes place the recess is divided into several recesses is, each a snap connection with the projection of the adapter. The probability, that the projection is one of the recesses hits as soon as a packaging machine Adapter with its projection on the locking connection can be brought about by reducing the recesses enlarge to the extent that the machine as a rule the snap connection always hits. Since it is but is a snap connection, the user can the adapter locked to the container at any time disconnect from the adapter if it goes over spread the substrate by using the arrowhead pulls over while overcoming the locking spring.

The invention thus creates a machine-friendly Training the locking connection, which the Manual work facilitates and the locking of the adapter with the container in a packaging machine correspondingly increased speed and high Degree of rationalization enabled.

For example, the arrow is largely unyielding and can consist of solid material. According to the characteristics of claim 2, it displaces the edges of the recess due to elastic deformation of the material, that behind the arrowhead back to its original Form returns at the back of the arrow sits behind the recessed edges that with this bring about a positive connection of the valve adapter. Vice versa will be when the snap connection is released resilient recess edges from the back of the arrow pushed outwards, thereby eliminating the form closure and the valve adapter becomes free.

The invention not only has the advantage that it is for the usual packaging machines favorable conditions creates, which also in the manual work pay off because it’s relatively easy Spend arrow in the recess by hand. she also has the advantage that they have closed recesses can provide an all-round positive locking achieve, which makes it more difficult for unauthorized persons Adapters from the container, in particular from the can cap to separate.

This advantage does not require a complicated one Shape of the locking connection. Rather, it is enough two opposite edges of the recess for that Suppress when manufacturing and dissolving the To provide snap-in connection. Then especially recommend Molds according to claim 4.

For such and other embodiments of the invention Shapes of the arrow and the recesses are suitable according to claim 5. The rounding of the wedge edge has the advantage that compact arrow formations arise that cause a short arrow length, reducing the depth of the recesses without the manageability of the valve adapter and its affect simple execution. This creates the additional advantage that the locked Valve adapter not turned around the shaft of the arrow can be and thereby a defined orientation of the adapter, which is useful for pressure sockets is that matched with the adapter Extension pipe parallel to the axis of the pressure cell hold as soon as the valve adapter is locked.

The embodiments of the invention which are implemented the features of claim 6 are possible, result in a practically backlash-free connection of the valve adapter, so that this in its predetermined assignment held to the valve or the pressure cell becomes. This enables appropriate containers Pack more easily and have it ready for sale. This can be done easily with the features of claim 7.

The end of the adapter tube closes for many pressure sockets with the pipe socket that is attached to the valve will, an angle. That is special the case of pressure cans filled with a liquid gas to apply the substrate. In these In cases, claim 8 enables alignment of the Extension pipe with the pressure cell for the production the parallelism of the axes.

In most packaging machines, the containers Bottled upright and finished. For in these cases it is advisable to look at the characteristics of the To make claims 9 and 10 use. Here plays the rotational position of the container relative to the fixed Machine station holding the adapter with its tab forward, no matter. Much more is at least one of the recesses in any rotational position met.

In particular, the invention can be appropriately mäp Apply claim 12 to pressure cans of the type described. Then it is appropriate to consider the features of the claim 11 to realize. Because here the recesses arranged in the valve cap of the pressure cell special measures on the Pressure cell to there the relevant parts of the locking connection to attach. The sockets can then have the usual smooth metal cylinder shape.

You will see the recesses on the circumference radial circle around the axis of symmetry of the container cap arranged and at a relatively short distance attach to ensure with maximum security that when advancing the adapter Arrow hits a recess. The then comparatively serve thin webs of adjacent recesses as springs of the locking connection, since the material is sufficient is elastic.

The embodiments of the invention are important for small containers, where the adapter with its adapter tube essentially axially parallel to Axis of symmetry of the container is held to in the shelves of self-service stores, such as hardware stores, space-saving packaging and installation to enable the goods. That is also why the characteristics of claim 13 useful, the recesses Can form slots whose longer axis runs perpendicular to the radial plane. Because in these Cases can be profiled accordingly arrow of the adapter in the recess Block rotary movements.

It also facilitates the insertion of the adapter projection essential in one of the recesses if remaining misalignments by an appropriate one Guide to be balanced, which is the adapter projection lead into the nearest recess. To For this purpose, the webs can be centered be profiled for the arrow of the adapter. Then ensures that each footbridge for the two adjacent to it Recesses has a centering slope.

The substrate contained in the can 101 is below the pressure of a propellant. The can valve is with a cap 2 covered on the can cylinder put on and with this friction and / or is positively connected. The generally with 3rd designated adapter can be with a sleeve 106th a pipe socket 109 on the not shown Apply valve and has two handles, which for the fingers of a hand with recessed grips are provided if with the help of the adapter Valve body actuated, e.g. should be tilted to clear the way for the substrate into the adapter tube 109 to give. Behind the one following the sleeve 106 Tube 109, the adapter tube 3 is kinked at 112, see above that its free end 111 with the pipe socket 106, 109 encloses an acute angle. To the free end 111 of the adapter tube can be an extension tube Slide on 110 and is frictional with this connected.

The adapter has one labeled 4 in FIG. 3 Ledge on one of its flanks. This serves as part of a particular from FIGS. 2 and 3 visible locking connection of the valve adapter 3 with the can cap 2.

As shown in FIG. 1, the protrusion is 4th formed as an arrow aligned transversely to the adapter. Accordingly, it has an arrowhead, one wedge with two bevels or wedge surfaces 36, 37 forms. The ends of the wedge 36, 37 are undercut at 14 and 15 and therefore counteract barbs effective in the direction of the arrow, which behind the edges 16 and 17 of the recess set, which is generally designated 5. The recess is rectangular and therefore has upper and lower Cut-out edges 18 and 19 on the vertical Join edges 16 and 17 together.

According to the exemplary embodiment, the arrow shaft is 13 with a slit-shaped penetrating the wedge Provide recess 35. The material of the tab 4 is elastic and therefore forms a spring into which the wedge is included.

The projection 4 is in the direction of its described Arrow with the rounded wedge edge 38 to the front pressed into the recess 5, so his arrowhead when the bevels 36, 37 emerge the recess edges 16 and 17 due to the slot 35 after, so that the material of the arrow is pointing inwards is displaced and the spring is tensioned. Here the chisel tip deforms until the undercuts 14 and 15 behind the inner jacket of the cap and the recess edges 16 and 17 are. As a result the elasticity of the material then relaxes the spring and the recess edges 16 and 17 arrive into the groove 21 formed by the undercut. The edges of the wedge bevels 36, 37 act as barbs against the direction of the arrow, while the rear Edge of further insertion of the arrow into the Recess 5 prevented when the positive engagement of the Snap connection is established.

When the snap connection is released, the projection becomes 4th pulled out in the opposite direction of the arrow, the Feather the arrowhead is cocked again and then the slopes 36 and 37 on the recess edges slide outward until the spring is released.

Deviating from the illustrated embodiment the projection 4 and the arrow 13 consist of solid material. In this case, the recess edges serve 16 and 17 as a spring with the arrowhead and the Barb is elastically deformed.

As can be seen from Fig. 2, the arrow is in pairs arranged bevels sharpened twice. How 3 can be seen from the undercuts 14 and 15 formed barbs on the flat sides 22, 23 of its shaft 13. As a result can after the production of the positive connection, in particular 3 shows the shaft 13 of the Arrow can not be rotated about its axis. Thereby is the position of the adapter shown in Fig. 1 guaranteed to the can.

The shape of the arrow can be further simplified, by omitting the groove 21 and adapting to the Undercuts 16 and 17 connects a smooth shaft. In this case, the distance between the undercuts 14 and 15, which form the barbs, from the tangential plane to an outer curve 24 of the Adapter tube 109 substantially the depth of the Recess correspond to a slight radial Game between the adapter 3 and the can or Ensure cap cylinder. Then can be prevented be that the adapter tube unintentionally a Angular position to the pressure cell.

The median plane of the chisel tip, indicated by the dash-dotted line Line 25 is shown in FIG. 2, closes with the dash-dot line in FIG. 1 drawn axis of the adapter tube 109 a acute angle. This ensures that the latched adapter tube is not out of its axially parallel position to the can cylinder in the Drawing plane of Fig. 1 can be pivoted.

The can 101 covers the can cap 102 which is placed on the pressure can 101, the can valve from. The adapter can be attached to the can valve Put on 103. The cover 102 has recesses 105 with which a projection formed on the adapter 103 104 is locked. The adapter itself points a sleeve 106 on a discharge pipe of the can valve put on and with this non-positive is to be connected. Handle recesses 107 make it possible User to press the sleeve 106 to do this Open exhaust valve. Then it flows in the pressure can contained substrate in the subsequent pipe 109, which is angled relative to the tube end 111. An adapter extension tube can be attached to the tube end 111 110 slide on and becomes non-positive held. The substrate can then be used the free end 108 of the adapter also to hidden ones Target areas such as gaps and undercuts judge.

The pressure cell 101 has according to that in FIG. 3 illustrated embodiment one in one Radius around the axis of symmetry of the container, because of the cylinder shape of the pressure can the longitudinal axis of the container represents, running groove 113 into which at the correct seat of the pressure cell cover is all-round collar 114 protruding inwards. The pressure can cap is in a packaging machine mechanically put on because the material of the Pressure cap resiliently yields. The Sliding movement of the cap 102 onto the can 101 the embodiment of FIG. 3 with the help of a web 116 limited. In the embodiment of the Fig. 4 serves the same purpose a circumferential projection 117 in the lid. The recess 105, which with the Protrusion of the adapter interacts each above that cooperating with the groove 114 Parts of the cap.

The exemplary embodiments according to FIGS. 4, 8, 9 and 11 all show a plurality of recesses 105, each with a snap connection the projection of the adapter can go. With these However, the recesses 105 are exemplary embodiments only on part of the circumference 118 of the cap 102 arranged in an angular range, the smaller than 90 °. The examples in FIGS. 5, 7 and 9 are preferred embodiments of the invention because each cap 102 over the entire circumference 118 a radial circle around the axis of symmetry of the container and thus the cap 102 is distributed are and therefore an angular orientation of the recesses 105 relative to the direction of movement of the adapter projection is not required.

6 are the recesses 105 of the pressure can cap 102 with slots 120 realized. In these cases, the closed Execution of the recesses all-round Form-fit achieved, so that the projection of the Adapters apart from the snap-in connection with the pressure cell cover 102 only canceled by a radial movement can be. The slots run parallel to the axis of symmetry 119 of the cap 102 and thus the Container that the pressure cell forms. As per the illustration 9, on the other hand, are the recesses 105 Slits 121, which are perpendicular to the axis of symmetry of the Cap 102 are arranged on the circumference 118 of the cap.

The cap 102 according to the embodiment of FIG. 7 and 6 is divided into two one-piece cylinders, the one another at the point designated by 122 pass over. The cylinder with the smaller diameter 123 joins the bottom of the cap while the cylinder with the larger diameter 124 itself extends from paragraph 122 to the open end of the cap. Paragraph 122 lies in a radial plane the cap and extends over the circumference 118 of the Cap. The recesses 105 are located on the shoulder 122 in the larger diameter cap cylinder 124. They are also designed as slots 125. Its longer axis runs perpendicular to the radial plane 118. However, the slots end at the base of the cap cylinder 123 with the smaller diameter 123. They thus connect the two Cap cylinder.

4 is with the recesses a latticework 128 in the can cap 102 realized. They are in this latticework Recesses 127, which are square to round Openings 129 are formed in the circumference 118 of the cap 102 could be.

The recesses 105 of the cap 102 in the exemplary embodiment 10 in turn consist of Longitudinal slots 130, the corresponding transverse slots 131 form a structural unit, which the Cross out longitudinal slots 130 at right angles. In the intersection area the slots 130 and 131 result the ends of springs 132 which give way elastically and a slight latching of the projection 104 on the adapter Ensure 103 with the cap 102.

In the embodiment of FIGS. 11 to 13 is in Circumference 118 of the cap 102 has a window 133 in it. Guides 134 are on the inside of cap 102 molded. These guides are to the lid opening 137 open towards it, so that a receiving plate from this side 136 are inserted into the guide 134 can until it comes to rest in management reason 138. Between the cap opening 137 and the window 133 there are molded catches 135, which the receiving plate 136 fixed in the guides 134. The Recording plate 136 carries the recesses 105, the through the window 133 for the projection 114 of the adapter are reachable. The mounting plate 136 can be used as flat molded part (see FIG. 12) are formed, which become elastic before insertion into the guide 134 deformed.

Thus, on the circumference 118 of the cap 102 any combination of slots 120, 121, 125 and intersecting longitudinal and transverse slots 130, 131 and / or openings 129 for receiving the Provide projection 104 of the adapter 103 to different Form the tab with the same Cap 102 to be able to lock.

The cap according to FIGS. 10 and 10a has on it a notch on the cover facing away from the opening 137, in the packaging machine as an alignment aid 139 is used. With this alignment aid 139 the cap 102 aligned to the arranged on the adapter 103 Projection 104 with sufficient probability in one of the recesses.

14 to 17 are the vertical edges chamfered the recess and form guide surfaces 140, with which the projection 104 is centered. The two Slopes 146, 147 of the wedge-shaped arrowhead 141 interact with the guide surfaces 140, as soon as the wedge tip 141 locks in the direction of the arrow is moved with the can cap 102. The arrowhead is again undercut at 148 and 149 and forms barbs with these undercuts. The barbs are supported when locked 148 and 149 on the associated edges of the recess 105 from. This creates a positive connection of the projection 104 with the can cap 102, but at Movement of the approach 104 in the opposite direction again is lifted, causing the adapter to separate from the can cap 102 can be separated.

The locking is therefore based on the spring action of the elastic material. In the case of the embodiment 12 the arrowhead itself becomes Spring whose elasticity is increased by the slit which is the wedge in the direction of the arrow and in the opposite direction enforced.

In the embodiment of FIG. 14, however, is one Unilateral arrowhead 151 is provided, the spring 152 of arrow 151 from an acute-angled bend the arrow shaft 153. Will the Arrow 153 pushed into recess 105 in the direction of the arrow, so the spring 152 deforms and forms after crossing the recess 105, a barb, which is on the inside of the pressure cap cylinder 102 supports.

In the exemplary embodiment in FIG. 15, arrow 154 is designed as a body of revolution, i.e. he has one outside cylindrical shaft 155 and a conical Point on that with an undercut 145 one Barb forms the positive connection with the can cap 102, as is basically the case in Connection with FIGS. 1 and 2 is explained above. The suspension, which is used to bring about the positive locking the latching is required can by Yielding the edges of the recess 105 or through Compliance of the arrowhead and thus the undercut 145 can be guaranteed.

The embodiment of FIG. 16 essentially corresponds the embodiment of FIGS. 1 and 2 with the exception that the glue surfaces at the end a fork 156 of the shaft 157 of the arrow is arranged are. The fork tines provide the spring action for sure. The locking takes place here also by the Yielding of arrow springs 158 and 159.

As soon as the latching has occurred, the lead becomes 104 on the outer cylinder 118 of the can cap 102 supported. A support 142 is used for this purpose the projection 104 is formed. Is the adapter with the can cap 102 locked, so ensures Support 142 a brace that fixes the adapter.
