Description

SPECIFICATION Package for accommodating and spraying small amounts of liquid The invention relates to a package for accommodating and spraying small amounts of liquid, said package being formed of two foil sheet portions which are joined together and further consisting of a compressible container for storing, a conterminous system of passageways for conveying and a nozzle for spraying said liquid.
Small packages are already known which accommodate shampoo pastes and which have a neck formed at one corner thereof. A handle is located at the free end of the neck which permits to userto twist off the neck, thereby removing the handle and forming an irregular passageway aperture with burrs and jutting edges. Since in order to hold the small package and user must exert pressure on the container with the shampoo, he runs the risk of squeezing the shampoo out immediately upon opening the passageway. In order to avoid this to a certain extent, it is also known to open a system of passageways by cutting off one corner, thus permitting not only the liquid but also the air inside the package to be expelled at the same time, thereby achieving a spraying effect.This spraying effect, however, is only effected when the package is held in a certain position while expelling the liquid. In this position, the air and liquid will be ejected in equal amounts, if at all possible. Moreover, the spraying effect is dependent on the fact that the cut be made in a precisely predetermined manner, since the system of passageways would otherwise have one or more apertures which would render the spraying effect inadequate, if not entirely impossible. Both factors limit the usefulness and commodity value of the known packages considerably.
By contrast, the object of the present invention is to provide a package for accommodating and spraying small amounts of liquid which is adpated to be opened in a precisely predetermined manner without outside means of assistance, for instance by the application of pressure exclusively.
To accomplish this object with a package explained in detail at the outset, the invention prop osesthatthe passageway system be designed to keep the liquid within the container and to accelerate said liquid when pressure is applied to the container, said passageway system terminating tangentially in at least one turbulence space provided with at least one central nozzle aperture.
This is advantageous in that the package can be opened without any means of assistance, for example scissors. The liquid is stored in the container and, when the nozzle aperture is closed off by a removable adhesive tab, is retained by the air in the passageway system or is separated by a predetermined rupture site from said passageway system which opens externally. For instance, if the thumb applies a first pressure to the container, the predetermined rupture site will by opened and some liquid will enter the system of passageways, thereby expelling the air located therein through the nozzle which is always open. As more pressure continues to be applied to the container, this empties its contents into the passageway system, the passageway system having a cross section which diminishes the size in the direction of the nozzle aperture, thereby accelerating the liquid.A twisting or angular momentum is imparted to the already accelerated liquid in the turbulence spaced before it emerges from the nozzle aperture in a finely atomized state.
An approximately conical mist of very fine fog-like droplets of liquid is formed in this way. In so doing, none of the liquid is lost and the conical spray always has a constant shape, since the system of passageways does not have to be opened by means of tools, but, together with the turbulence space and the nozzle aperture, is already open when manufactured and remains open even during transport and storage of the packages. The manufacture of the package is simplified, since the foil sheet including the container, the system of passageways and the turbulence space only needs to be stamped or deep-drawn. The container is thereafter filled and the shaped foil sheet is joined with a flat foil sheet.
As a last step, the individual, filled packages can be cut off the train of packages. This can occur at the same time the foil sheets are joined together, preferably by fusing them together.
The package is designed for a single use and can accommodate many different types of liquids. It can be utilized in particular for perfume,toiletwater, hair spray and the like. It can also be used as well to spray sterilized or sterilizing substances in the field of medicine. The closed package, if desired packed in another envelope, can be sterilized by ultraviolet radiation, for example, the outer envelope being removed in the operating theatre, the surgeon pressing on the container to open the predetermined rupture site and directly sterilizing the site to be treated. It is an advantage that the package contains no propellants and does not require any foreign bodies either to close or to open it. The spray package can also be used in the food and beverage sector, for example for oil or vinegar.The container can even be designed as a mixing container in which the first pressure applied removes or ruptures a partition, thus enabling the liquids located inside the container to mix with one another before they enter the system of passageways and are sprayed out of the package.
The liquid may also be a specific amount of varnish which is sprayed onto damaged parts of motor vehicles, for instance, for the purpose of repairing them.
The package is also suitable for spraying other liquids such as insecticides and herbicides (weed killers).
In order to intensify the spraying or atomizing effect, it is also provided that two passageways be provided between the container and the turbulence space which are offset at an angle of 1800 and terminate tangentially in said turbulenece space.
If the compressible container, the passageways and the turbulenece space are formed in a deepdown polyethylene foil sheet, it is expedient to make the nozzle aperture at the same time the foil sheet is deep-drawn. This aperture is then located in the inherently stable wall of the turbulence space which is just as insensitive to impact as are the walls of the passageways, since the original thickness of the polyethylene foil remains essentially the same.
The drawings illustrates embodiments of the invention which will now be explained in detail with reference to the following description of the Figures, in which: Figure 1 shows a top elevation of the deep-drawn foil sheet, Figure 2 shows a side elevation of the deep-drawn foil sheet according to Figure 1, Figure 3 shows a side elevation of the planar foil sheet, Figure 4 shows a top elevation of the planar foil sheet according to Figure 3, Figure 5 shows a top elevation of the deep-drawn foil sheet joined to the planar foil sheet, Figure 6 shows a side elevation of the deep-drawn foil sheet joined to the planar foil sheet according to Figure 5, Figure 7 shows a side elevation of the package after formation of a predetermined rupture site in accordance with a first embodiment, Figure 8 shows a side elevation of the package after formation of a predetermined rupture site in accordance with a second embodiment, Figure 9 shows a top elevation of the package according to a third embodiment, Figure 10 shows a side elevation of the package according to Figure 9, Figure 11 shows a side elevation of the package in accordance with a fourth embodiment.
Figures 1 and 2 show a segment of a deep-drawn polyethylene foil sheet 1 which has been separated from a trail or web of foil. The polyethylene foil sheet 1 is expediently translucent. It has a turbulence space 2 connected through two passageways 3 and 4 4to a container 5 which is compressible and designed to accommodate the liquid. The container 5 has a greater depth than the turbulence space 2 and passageways 3 and 4 so that the liquid is accelerated within the passageways 3 and 4. In the first embodiment, a planar foil sheet 6, preferably aluminium foil, has a nozzle aperture 7.
When joining the deep-draw foil sheet 1 and the planar foil sheet 6 as indicated by the arrows between Figures 2 and 3, the nozzle aperture 7 is aligned accurately to the center of the turbulence space 2. The two passageways 3 and 4 are provided between the container 5 and the turbulence space 2 and terminate tangentially in said turbulence space 2 offset at an angle of 1800. Both passageways can have a conical configuration and can taper from the container 5 toward the turbulence space 2. The nozzle aperture 7 of the turbulence space 2 is closed off by a removable adhesive tab 27 in accordance with Figure 6. The air located inside the two passageways 3 and 4 keeps the liquid in the container 5.Passageways 3 and 4 have parallel passageway segments 9 of substantially constant cross section as well as approximately right-angled bent portions 10 at the free ends thereof, said bent portions tapering to a great extent and terminating tangentially in the turbulence space 2 at diametrically opposite positions.
The tab 27 can be replaced by a predetermined rupture site 8 provided between the passageway system 3, 4 and the container 5. In addition to the container 5, an antechamber 11 can be provided adjacent the predetermined rupture site 8 which communicates with both passageways 3 and 4, but which remains separated from the container 5 by the predetermined rupture site 8 as long as the liquid is enclosed in the container 5. In order to more easily rupture or separate the predetermined rupture site 8, the container 5 can be beveled adjacent the predetermined rupture site 8 - as illustrated at 12 - to exert a wedge action on the predetermined rupture site 8 when the finger applies pressure in the direction of the arrow 13 in Figure 6, thus making iteasierto separate foil sheets 1 and 6 in this way.
In the embodiment in accordance with Figure 7, the predetermined rupture site 8 is designed as an adhesive connection 14 by cementing or glueing a groove 17 stamped into the deep-drawy foil sheet 1 to a locaton 16 on the planar foil sheet 6.
In the embodiment in accordance with Figure 8, the predetermined rupture site 8 is formed by deep-stamping it 15 upon joining or subsequent to joining the deep-drawn foil sheet 1 to the planar foil sheet 6, thereby producing in the planar foil sheet 6 a projecting bead 18 which sealingly engages a recessed bead 19 in the deep-drawn foil sheet 1.
In the embodiment in accordance with Figures 9 and 10, the planar aluminum foil 6 is overlaid with a thin thermoplastic foil 20 such as a polyethylene foil.
Both the aluminum foil 6 and the polyethylene foil 20 do not have any holes or perforations and the nozzle aperture 7 is formed in the center of the turbulence space 2 at the same time the deep-drawing operation is executed. After the container 5 has been filled with liquid, the deep-drawn polyethylene foil sheet 1 which is open at the top is covered by the planar aluminum foil 6 which has also been overlaid with a thin polyethylene foil 20, whereupon the foil sheets are fused together by heat and pressure such that a container for the liquid is formed which is closed on all sides, whilst the entire system of passageways 11,9, 10 remains open and communicates with the turbulence space 2 via the nozzle aperture 7.The juncture between the thin polyethylene foil 20 and the planar aluminum foil 6 is so weak at least in the area of the predetermined rupture site 8 that, when an initial pressure is applied to the container 5 as shown by arrow 13, the thin polyethylene foil 20 will tear away from the aluminum foil 6 and be opened such that the liquid will be able to flow unimpededly into the passageways 3,4 adjacent the beveled area 12 or the open predetermined rupture site 8.
In the embodiment in accordance with Figure 11, the container 5 is designed as a dual-chamber container, one chamber 21 being filled completely with a liquid, whilst another chamber 22 containing air in addition to another liquid. Between the two chambers 21 and 22 there is located a partition 23 which ruptures when an initial pressure is applied to the chamber 21 as indicated by arrow 13. The liquids from both chambers 21 and 22 can be mixed in this way inside the container 5. The predetermined rupture site 8 is thereafter opened by further pressure, whereupon the mixture can be sprayed by expelling it from the nozzle aperture 7 by continuous application of additional pressure.
The planar foil sheet 6 can also consist of plastics, for instance polyvinyl chloride (PVC), and can also be overlaid with the thin polyethylene foil 20. Alternately, the deep-drawn foil sheet 1 and the planar foil sheet 6 can have an integral design, both foil portions expediently being joined together along one of the longer edges by means of a folded edge.
After filling the container 5, the planar foil segment 6 can be folded over the deep-drawn foil portion 1.
Subsequently both foil portions are sealingly fused together.
