CONTAINER FOR STORAGE AND PREPARATION OF A PLANT PROTECTIVE MATERIAL CONTAINING AT LEAST TWO COMPONENTS BACKGROUND OF INVENTION 1. Field to which invention relates The present invention relates to a container for storage and preparation of a plant protective material containing at least two components.
2. Prior proposals The German Pat. Specification 1,939,086 describes a container for storing and preparing a plant protective material containing at least two components in the case of which all components intended for a ready-to-use spraying solution are so accommodated separately that mixing only occurs when the user desires it and takes suitable steps. This can be achieved because in the container containing a solvent a capsule provided with several separate chambers extends and the capsule is firmly connected with the container and the chambers comprise different plant protective components. For mixing the individual plant protective components it is necessary in this respect to pierce the bottoms of the chambers of the capsule with a suitable implement, for example with a plunger or with the projecting part of aspray gun.
In this respect it is possible in many cases for the plant protective components contained in the chambers of the capsule not to be fully removed from these chambers after the piercing of the chamber bottoms so that residues of in some cases highly poisonous plant protective components remain in the capsule and there is the danger that residues of the highly concentrated plant protective materials may remain on the plunger or projecting part ofthe spray gun used for piercing the bottoms of the chambers. Such residues lead to the danger that the user may come into contact with the highly concentrated active substances remaining on the plunger or projecting part of the spray gun when it has been withdrawn from the container.
SUMMARY OF INVENTION One aim of the present invention is to provide a container of the above-mentionedtype in the caseof which complete emptying of thechambers of the capsule is guaranteed and in the case of which the mixing of the individual components with the solvent does not require any devices which must be removed out of the container again and on which highly concentrated active substances could remain as a contamination.
The present invention consists in a container for storing and preparing a spraying liquid comprising at least two components, and which is at least partly filled with a solvent, and a capsule comprising at least two separate chambers extends into the container and is connected with it in a fixed manner, the chambers containing different plant protective components, characterised by a sliding sleeve for pressing out the separating bottoms of the chambers with an external diameter substantially corresponding to the internal diameter of the capsule, the sliding sleeve being adapted to remain in the capsule after pressing out the separating bottoms.
This sliding sleeve can in an advantageous manner be adapted to be plugged on the screw connection for the neck of the container so that the container after the pressing out of the separating bottoms of the capsule is initially closed and mixing together of the active substances contained in the capsule with the solvent contained in the container can take place, for example by shaking.
It is furthermore possible to provide a rod-shaped extension in the interior of the screw closure, on whose free end the sliding sleeve can be plugged. In this case the sliding sleeve can be plugged in a concentric telescopic manner on this extension for transport and thus remains in the interior of the neck of the container so that it cannot be lost. For piercing the separating bottoms the sliding sleeve is removed after unscrewing the closure cap and after tilting through is plugged on the end of the extension so that a pushing out of the separating bottoms as far as the end of the capsule is possible.
Since in the case of the use of several active substances in the capsule and of the simultaneous accommodation of the sliding sleeve in the neck of the container the capsule can extend to a substantial extent into the container it is advantageous to provide the sliding sleeve on the end which can be plugged on to the extension with a tapered part, which after the pressing out of the separating bottoms comes to lie at a position immediately under the neck shoulder of the container and that the part of the capsule, lying at this position, has an opening for the complete removal of the solution in thecontainer. In this manner a complete emptying of the container is possible even without additional implements, such as for example the take-in tube of a spray gun.
The opening formed in the capsule can in this case be closedby a separating wall or partition constructed as a hollow plug for transport and before use, the wall of this hollow plug covering the opening.
LIST OF SEVERAL VIEWS OF DRAWINGS The invention will now be described in detail in what follows referring to an embodiment shown. in the accompanying drawings.
FIG. 1 is a cross-sectional view of the container with the capsule in the condition fixed for transport.
FIG. 2 shows a cross-sectional view similar to FIG. 1 after the pushing out of the separating bottoms for mixing the active substances with the solvent.
FIG. 3 shows a .view of the closing cap and the sliding sleeve.
FIG. 4 shows a view of the capsule for receiving the active substances.
DESCRIPTION OF PREFERRED EMBODIMENT In FIG. 1 the container for storing and preparing the plant protective agents is denoted by the general reference numeral 1. This container consists of a bottle body 2, with whose bottle neck 7 a capsule is connected for receiving the individual active substances. In this capsule several chambers 3, 4 are provided for receiving the individual active substances and the chambers are sealed off by the separating bottoms 21-23. In the embodiment shown only two chambers are provided but the number of chambers can, however, be changed as may be desired. The uppermost separating bottom 23 is constructed as a hollow plug with a wall 28 for reasons which will be explained presently.
In the upper part of the capsule 16 or of the bottle neck 7 a sliding sleeve 25 is accommodated, which surrounds an extension 26 of a closing cap 24 in a telescoping manner.
The closing cap 24 has an internal screw thread, which cooperates with an external screw thread on the upper end of the bottle neck 7 so that the closure cap 24 can be screwed onto the bottle neck to make a liquid-tight seal.
The sliding sleeve 25 has a tapered p'art 25a at its one end and the internal diameter of this part corresponds to the external diameter of the free end of the extension 26 of the closure cap 24. This extension preferably has at its free end an end section 29 with a shoulder 290 formed by this. This shoulder acts as an abutment for the end of the tapered part 250 of the sliding sleeve 25 in the plugged together condition.
For mixing the active material in the chambers 3 and 4 of the solvent 5 in the bottle body 2 the closure cap 24 is unscrewed, the sliding sleeve with the tapered part 25a is plugged on the free end of the extension 26 of the closure cap 24 and the arrangement formed in this manner is pressed under pressure into the eapsule so that the upper separating bottom 23 constructed as a hollow plug and the further separating bottoms 21 and 22 are pressed out ofthe capsule. The pressing through in a sliding manner of the hollow plug through the capsule ensures that complete emptying of the capsule takes place.
FIG. 2 shows the container 1 with the sliding sleeve 25 completely inserted into the capsule 16. Since the sliding sleeve 25 is made hollow emptying of the container through this sliding sleeve 25 is possible.
In order to make possible complete emptying of the container even in the case ofa capsule 16 extending for a considerable distance into the container, an opening 27 is placed at a position immediatley underneath the bottle neck 7 in the capsule 16 and this opening 27 simultaneously lies in part ofthe tapering part 25a of the sliding sleeve 25. In this manner a complete emptying of the container 1 is possible.
This opening 27 is closed before use by the wall 28 of the separating bottom 23 constructed as a hollow plug. Also during the insertion of the sliding sleeve 25 this opening is closedbefore the complete insertion of the sliding sleeve, since the outer wall of the sliding sleeve covers the opening.
FIG. 3 shows the closure cap 24 with the extension 26 and the closure cap 24 separately. As can be seen from figure 3 the end of the extension 26 has a section 29 with a reduced diameter, by means of which an abutment shoulder 29a is formed. The sliding sleeve 25 has a tapered section 25a with an internal diameter, which corresponds to the internal diameter of the part 29 with the reduced diameter. In this manner the sliding sleeve 25 can be plugged on the end of the extension 26. As can be seen fron FIG. 1 the diameters of the extension 26 and the sliding sleeve 25 are so selected that the sliding sleeve 25 can be plugged in a telescoping manner on the extension 26 before use in the condition ready for transport of the container 1 and therefore it takes up little space.
Naturally it is also possible to provide a correspondingly longer sliding sleeve or a sliding sleeve with an extension abutment, which is delivered with the container and also remains in the capsule after pressing in of the separating bottoms. In this case an extension on the closure cap is not necessary.
FIG. 4 shows the capsule 16 separately. This capsule can have a flange 30 at its upper end. The flange can be connected with the upper end of the bottle neck 7 by welding or in an other suitable manner.
