Description
A DEVICE FOR PROTRACTED RELEASE OF ACTIVE SUBSTANCES,
PERFUMES AND SIMILAR VOLATILE SUBSTANCES
The invention relates to a device for protracted delivery of active substances, perfumes and similar volatile substances which consists of a bottle-like storage container, in particular made of glass, the delivery opening of which can be closed by a screw-off cap and, instead of the cap, a holder, which can be removably fixed on the delivery opening, for a cellulose plate or a similar absorbent plate as well as a wick or similar suction means which is connected to the plate and which is engaged in the storage container, in particular as far as the bottom of the latter.
A device of this kind is known in the state of the art, wherein the storage container is a glass bottle, hexagonal in cross-section, which comprises a cylindrical neck, tapering to the opening, with an external thread. To close this bottle-like storage container a threaded plastic cap is screwed on the neck of the container. In order to be able to vaporize the liquid contained in the said storage container in a regular manner over a longer time period, this device is provided with a separate holder which can be screwed on the mouth of the container instead of the closing cap. This holder comprises a support surface built in the form of spokes and a rim on which a cellulose plate is arranged.A strip of material is cut attached to or is cut out of the cellulose plate which strip is inserted through an appropriate hole made in the holder into the interior of the storage container and when the holder is screwed on the storage container it reaches the bottom of the latter. Thereby the liquid present in the container is sucked up by capillary action and delivered to the cellulose plate arranged on the outside of the holder so that the large surface of the plate is available as an evaporation surface.
The whole device can be covered by a decorative cap with ventilation openings which is removably fixed to the container and is reusable.
The container itself, which in the state of the art is made of glass, can after suitable emptying be recycled as used glass. The closure cap, which in the state of the art is made of plastic, can also be sent for recycling of the plastic. The holder, which also is made of plastic, but a different type of plastic, can also be sent for reprocessing. In the case of such devices it is disadvantageous that handling is to some extent difficult for the user because the latter must first remove the cap from the container and then the spearately supplied holder, together with the absorbent plate, must be correctly screwed onto the container for proper operation.
Starting from this state of the art, the aim of the invention is to provide a device of this general type, which consists of only a small number of individual elements and which is easier to use.
To achieve this objective, the invention proposes that the holder is formed on the cap on the opposite side to the threaded side of the cap and preferably consists of at least two fingers projecting axially from the base of the cap, the facing surfaces of which are provided with locating notches or preferably with portions of a screw thread path, the absorbent plate is arranged on the side of the base of the cap provided with the holder, and a suction means, in particular a wick, is held in the container, the end nearest the cap of which suction means projects out of the mouth of the container, whereby the cap in the closed position engages over the projecting end of the suction means and in the oppositely directed working position the end of the suction means is held bearing against the absorbent plate.
The holder is made in one piece with the cap and so in this case there is a single element, preferably made of plastic, and not two individual elements. By means of the appropriate arrangement of the wick and the absorbent plate it is ensured that, on the one hand, in the transportation position the cap can be screwed on the container in order to close the container, whereby at the same time the wick is covered and the holder together with the absorbent plate is permanently fixed to the container. For proper use it is only necessary to screw the cap off the container and to fix it again on the container in the opposite direction, in particular to screw it on the container again, as a result of which the wick is then brought into contact with the absorbent plate and evaporation of the active material contained in the bottle can occur.
Plastic is preferably used for the holder which is made in one piece with the cap. However it is also possible, to use sheet metal or the like instead of plastic. As a result of the construction in accordance with the invention, not only is the handling simplified but also the packing of the device for transport and for displaying for sale in sales outlets is simplified, since in all cases a single protective outer packing can be provided which can itself also be dispensed with, since all the individual elements are fixed to the container itself and consequently no external packaging is required to hold and protect the necessary functional elements.
A preferred further development consists in arranging that the suction means consists of a cylindrical wick, having a permanent shape, made of fibrous material
Furthermore it is preferably arranged that a wick holder is inserted in the mouth of the container which can be pushed into the mouth as far as an outer flanged edge and comprises a tubular opening in its centre for the wick to pass through.
In this case it is preferably arranged that the tubular opening for the wick to pass through is provided with a sleeve which has a flanged edge connected by means of a closed, approximately radially directed wall portion which optionally contains a ventilation hole, which sleeve can be pushed into the mouth of the container to form a positive fit, or optionally a nonpositive fit, the wall portion being inclined towards the bottom of the container, sloping away from the sleeve wall to the opening for the wick to pass through.
In order not to deform the wick when screwing on the cap to close the container or to push it into the container, it is proposed that the cap should comprise a cylindrical, blind end cavity in its base in which the projecting end of the wick engages in the closed position.
The cavity forms an overhang projecting away from the container which is adapted to the projecting end of the wick so that on screwing on the cap this projecting end of the wick is not deformed or pushed into the container.
In addition it is preferably arranged that radially directed support surfaces are formed on the wall of the cap on which the absorbent plate is supported.
This arrangement is adopted for this purpose so that the absorbent plate is supported by the support surfaces in the transportation position and consequently deformation of the absorbent plate or damage of the latter is prevented. In the working position, in which the holder is attached on the container mouth, the support surfaces are located on the side of the absorbent plate facing away from the container and thus form a sort of protection against contact by the user.
Preferably it is arranged for this purpose that in a known manner the support surfaces are formed by projections arranged like spokes and a rim.
It can also be arranged that the support surfaces are formed by ear-like projections projecting from the cap cover.
Preferably it is arranged that the bearing planes of the support surfaces for the absorbent plate extend at the same level as the base of the cavity in the cap which also forms a support surface for the absorbent plate.
This arrangement provides, on the one hand, an additional support for the absorbent plate in the transportation position, when the cap is
Screwed on the container mouth, whereas in the opposite orientation of the cap, namely when the holder is screwed on the container mouth, the base of the cavity ensures that the absorbent plate is held firmly against the wick projecting out of the container mouth. The desired movement of liquid from the container through the wick into the absorbent plate is thus ensured.
For easier manipulation it is provided that the support surfaces comprise a rim which surrounds the radial end edge of the absorbent plate and which projects in the same direction as the fingers above the edge of the support surfaces.
The rim which surrounds the radial end edge of the absorbent plate can be used as a handle when screwing on or screwing off the closure cap or the holder without there being any risk that the absorbent plate will be deformed radially by manual operations.
Preferably it is arranged that the absorbent plate is circular in plan view.
It is also preferable that the plate contains engagement slots for the fingers to pass through.
Alternatively, or additionally, it can also be arranged that the support surfaces are formed by a disc which can be pushed onto the cap wall so that it is positively engaged or forms a friction fit.
It is true that more work and expense is necessary for this because an additional separate part must be manufactured and mounted, however as a result of this construction it is ensured that even with the device arranged in the working position, that is when the holder screwed on the container mouth, the absorbent plate is supported from below by support surfaces, for which purpose it is arranged in particular that the disc is located on the side of the absorbent plate facing away from the base of the cap.
In addition it is arranged in a known manner that a reusable decorative cap comprising ventilation slots or holes is removably attached to the container.
Embodiments of the invention are shown in the drawings and are described in more detail, by way of example only, with reference to the following drawings in which:
Figure 1 shows a first embodiment in the working position;
Figure 2 shows the same in the transportation position;
Figures 3 and 4 show details in top view;
Figure 5 shows a detail seen in a view corresponding to Figure 2; and,
Figures 6 to 10 show a second embodiment in similar views.
The device for protracted delivery of active substances, perfumes or similar volatile substances consists substantially of a bottle-like storage container 1 made of glass, the delivery opening 2 of which can be closed by a screw-on cap 3. Furthermore, instead of the cap 3, a removably attachable holder 4 for a cellulose plate 5 is arranged on the delivery opening 2, and a wick 6, which in the working position of the device is connected to the plate, is engaged in the storage container 1 as far as the bottom of the latter.
According to the invention, the holder 4 is formed on the cap 3 on the other side to the threaded side of the cap 3. In the embodiment example the holder 4 comprises two diametrically opposite fingers 7 projecting axially from the base of the cap, the facing surfaces of which are provided with sections of a screw thread 8. The cellulose plate 5 is arranged on the side of the base of the cap provided with the holder 4. A wick 6 is held in the container 1, and the end of the wick nearest the cap projects beyond the mouth of the container 1. Consequently the cap 3 in the closed position, shown in Figure 2 and Figure 7, engages over the projecting end of the wick 6, whereas in the opposite, working position, shown in Figure 1 and Figure 6, the end of the wick 6 is held bearing against the cellulose plate 5.The wick 6 has a cylindrical structure and consists of shape-retaining fibrous material. In order to ensure holding and centering of the wick 6 in the correct position, a wick holder 9 is inserted in the mouth of the container 1 which can be pushed into the mouth of the container 1 as far as an outer flanged edge 10. In the centre the wick holder 9 comprises a tubular guidance opening 11 for the wick to pass through which may also comprise longitudinal grooves for ventilation purposes.
The tubular opening 11 for the wick to pass through is, connected by an approximately radially directed wall portion 12, which optionally may also contain a ventilation opening, constructed in one piece with a sleeve comprising a flanged edge 10 thus forming the wick holder 9. The wall portion 12 is inclined inwards from the sleeve wall to the opening for the wick to pass through, sloping down towards the container bottom so that any excess liquid secreted from the wick is trapped there and can be led back into the container through an appropriate opening near the opening 11 for the wick to pass through.
The cap 3 contains in its base a cylindrical blind end cavity 13 into which in the closed position shown in Figure 2 or Figure 7 the projecting end of the wick 6 engages.
Radially directed support surfaces 14 are formed on the outer wall of the cap 3 on which the cellulose plate 5 is supported in the closed position shown in Figure 2 or Figure 7. In the embodiment example shown in Figures 1 to 5 the support surfaces 14 are formed by projections like spokes and a rim 15, as can be seen in particular in Figure 4. In the embodiment example shown in Figures 6 to 10 the support surfaces 14 are formed by projections 16 projecting like ears from the outer wall of the cap, as can be seen in particular in Figure 9. The bearing plane of the support surfaces 14 for the cellulose plate 5 extends at the same level as the base of the cavity 13 in the cap 3, as a result of which the bottom of the cavity 13 is also available to act as a support surface for the cellulose plate 5.In the working position shown in Figures 1 and 6, as a result of this construction the base of the cavity 13 holds the cellulose plate 5 firmly bearing against the projecting end of the wick 6 so that a regular transport of liquid is ensured.
The support surfaces 14 comprise in addition a rim 17, surrounding the radial end edge of the cellulose plate 5, which projects from the edge of the support surfaces 14 in the same direction as the fingers 7.
As can be seen in particular in Figures 3 and 8, the cellulose plate 5 has a circular structure and the said plate contains engagement slots 18 for the fingers 7 to pass through.
By means of the embodiment of the device in accordance with the invention, explained in the drawings with the help of embodiment examples, simplified manipulation is ensured and also during transportation it is ensured as far as is possible that the individual functional elements required cannot be lost.
The invention is not limited to these embodiment examples but can be altered in many ways within the scope of the appended claims.
