Definitions

• This invention relates to a pack containing a cleaning powder.
• cleaning powders Consumers expect cleaning powders to be pleasantly perfumed and they expect this perfume to be noticeable both on opening the pack and on use of the powder.
• modern cleaning powders increasingly contain components which adversely affect the stability of perfumes, with the result that off-odours can develop and that the impact of the perfume is reduced.
• components which adversely affect the stability of perfumes, with the result that off-odours can develop and that the impact of the perfume is reduced.
• examples of such components are chlorine bleaches such as sodium hypochlorite and sodium trichlorocyanurate, and oxygen bleaches such as sodium perborate and sodium percarbonate, if desired, in combination with an acid bleach precursor such as tetraacetylethylenediamine.
• the present invention provides a pack containing a cleaning powder, the inside surface of the pack, or part thereof, being impregnated with a perfume.
• packs containing perfumed cleaning powder which are made from absorbent material carry a small amount of perfume which has become absorbed either directly from the solid powder or from the vapour phase.
• the packs of our invention carry relatively large amounts of perfume which has been applied to their inside surfaces from the liquid phase.
• the perfume is applied to the pack in the headspace region, that is in the region of the pack vacated by the powder as it settles down due to mechanical handling after packing.
• Application of the perfume to this region of the pack gives the greatest opportunity for the perfume to be noticed once the pack is opened.
• the material from which the pack is made should be capable of absorbing perfume and of releasing it again.
• Cardboard and coated cardboard normally used for carton or drum manufacture do in fact meet these criteria.
• Canadian Patent No 971,135 which relates to a carton principally designed for holding facial tissue:.
• the carton is adapted for perfume to be deposited between the sealing flaps and for the perfume vapour to communicate with the tissues inside the carton.
• the object of this invention is to prevent liquid perfume from coming into contact with the tissues in order to prevent problems of allergy and skin sensitisation. In our invention these latter problems are much reduced because of the difference in mode of use between cleaning powders and toilet tissues and so our method of impregnating the pack is likely to be more effective and less expensive than the proposal in Canadian Patent No 971,135.
• the perfume may be applied to the pack, or to a blank for the pack, by any suitable method. Spraying the perfume, either neat or in solution in a suitable perfume diluent, directly onto the appropriate region of the blank is a simple and effective method of carrying the invention into effect.
• the invention is particularly applicable to cartons of rectangular shape which are sealed at the top and bottom by overlapping flaps or by a so-called flip-top closure.
• Such cartons are generally erected by machine from flat blanks, and it is a relatively simple matter to arrange for the blanks to be sprayed with perfume at the region which will define the headspace in the filled pack. Alternatively, it is an equally simple matter to arrange for the erected but as yet unfilled carton to be sprayed.
• Each carton in the first set was filled with 3 kg of a fabric washing powder which had been sprayed with 6 gms perfume.
• the cartons in the other set were filled with the same fabric washing powder which had been sprayed with 5 gms perfume.
• the remaining 1 gm of perfume was sprayed onto the inside of the top of the cartons. In other words, 16.7% of the perfume was applied to the cartons in the second set.
• the two sets of cartons containing the fabric washing powder were then sealed, divided into three groups and stored for four weeks under three different storage conditions; ambient temperature and relative humidity (RH), 28°C/70% RH and 37°C/70% RH.
• RH ambient temperature and relative humidity
• the three sets of cartons containing fabric washing powder were assessed subjectively by a trained panel, and also instrumentally.
• the instrumental assessment was carried out at the end of the storage period before the cartons were opened, by withdrawing 5 ml of the vapour in the headspace of the carton using a hypodermic syringe. The vapour was then injected into a Carbowax 20M (registered trade mark) chromatography column and the eluent was passed onwards to a gas-liquid chromatography column.
• the results of this assessment are given in Table 1.
• Each caiton in Set 1 was filled with 3 kg of a fabric washing powder which contained 8 gm of perfume capsules and which had been sprayed with lg of the same perfume.
• the capsules were gelatin-based and were prepared as described in US Patent No 2,800,458. They were 2.5 microns in diameter and consisted of approximately 60% by weight of perfume).
• Each carton in Set 2 was filled with 3 kg of powder which was identical with the first powder except that it contained 9 gm of the perfume capsules and no perfume was sprayed on.
• Each of the third set of cartons (Set 3) was sprayed with 1 gm of perfume and filled with 3 kg of powder which was identical with that used for Set 2 except that it contained 8 gm of perfume capsules.
• Each carton was sealed and the three sets were then divided into two sub-sets.
• the first sub-set was stored for four weeks at ambient temperature and relative humidity, and the second sub-set was similarly stored at 37°C and 70% relative humidity.
