DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to bottles for multi-phase liquid products.
BACKGROUND ART
For cosmetic purposes it is known to use two-phase liquid products. for example hair setting lotion or products similar to setting lotion with a so-called top admixture. The top admixture consists of isoparaffins as the second phase. These are liquids which are highly volatile at room temperature and even more so at higher temperature, so that a sealed packing involves great difficulties. In addition isoparaffins have an extremely high leakage capacity. They have a low density and therefore always float on top in a two-phase mixture.
If these liquid products are bottled in conventional bottles, then considerable losses in top admixture arise as a result of diffusion and leakage in the region of the closure. For economic reasons, the closure caps of the bottles are provided with integrated sealing elements. in which case it is not possible to avoid capillaries and microscopic gaps between the neck of the bottle and the sealing element. The seals which on account of economic and functional requirements are mostly manufactured from polyolefins, only have a low diffusion density with respect to isoparaffins.
DISCLOSURE OF INVENTION
The object of the invention is therefore to design the closure for multi-phase liquid products in such a manner that liquid losses as a result of diffusion and leakage are avoided. According to the invention, this is achieved in an advantageous manner in that, in bottles filled with multi-phase liquid products, the bottle closure is designed as a base and the bottle is shaped such that it cannot stand with its opening facing upwards.
In bottles designed in accordance with the invention, the highly volatile top admixture having a lower density is isolated in a part of the bottle remote from the opening, so that the highly volatile liquid is not in the opening/closure region and losses during storage are thereby avoided. This therefore prevents both a visible drop in the filling level and an actual loss of effectiveness of the entire product. The bottle and the closure can be manufactured economically and there is no need for expensive sealing, which would also result in awkward handling.
In a preferred embodiment a screw or clamping closure extends over the neck of the bottle. In order that the bottle may also be stored on its side, it is expedient to provide the latter with at least one lateral bearing surface.
BRIEF DESCRIPTION OF DRAWINGS
The invention will be described further, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 shows a bottle in longitudinal section, standing on its closure; and
FIG. 2 shows the bottle according to FIG. 1 lying on its side.
BEST MODE FOR CARRYING OUT THE INVENTION
The bottle 1 illustrated has a neck 2 and a base 3 which is curved outwards and which prevents the bottle 1 standing with the opening 4 facing upwards. A closure cap 5 is screwed or clamped onto the neck 2 of the bottle, extends laterally over the neck 2 of the bottle, and has an outer ring 6. The outer ring 6 has approximately the same diameter as the bottle 1, so that there is a base 7 which corresponds to or is larger than the diameter of the bottle. As can be seen from the drawing, the outer ring 6 of the closure cap 5 is in an end-to-end abutting relationship with the main wall of the bottle 1. Therefore, in the position shown in FIG. 1 not only the central ring of the closure cap 5 supports the neck 2 of the bottle 1, but also the outer ring 6 of the closure cap 5 supports the main wall of a bottle 1. The bottle may be provided with one or more lateral bearing surfaces so that it can also be stored lying on its side (FIG. 2).
As can be seen from the two Figures, the highly volatile top admixture 11 of isoparaffins, which floats on top of the liquid, is not in the immediate region of the bottle closure, both in the standing position according to FIG. 1 and the position according to FIG. 2 where the bottle is on its side, so that storage losses
