Definitions

the present invention relates to an aerosol container in which a valve cap is fitted into an opening at the neck and particularly, to a raw material which is used for producing the aerosol container.
an aerosol container is which a valve cap is fitted into an opening at the neck
the one having such a structure as shown in a cross-sectional view of Figure 2 is disclosed in, for example, Japanese Patent KOKAI (Laid-Open) No.76993/88.
This structure is the one in which ring recess (3) is formed on the neck of the container body (1); and valve cap (7) is fitted into the above-mentioned neck region (2) and the lower end (8) of the valve cap (7) is narrowed down into the above-mentioned recess (3), wherein valve housing (5) for valve (4) extending into the inside of the container, is airtightly supported with sealing member (6).
a high pressure-resistant property is requested for the container in itself, so that a resin such as polyethylene terephthalate is commonly used in the form of a single substance for a raw material of the container.
an aerosol container in which a valve cap is fitted into an opening at the neck of the aerosol container, characterized in that a raw material forming the aerosol container is a high molecular compound having a glass-transition temperature of 74°C-100°C.
the aerosol container of the present invention when the internal pressure thereof has come up to such a degree as the contents would be exploded, the aerosol container is expanded in itself to lower the internal pressure, so that a burst of the container can be avoided.
the glass-transition temperature of a raw material for the aerosol container is set in the range of 74 °C to 100°C , preferably 75°C to 85°C.
this glass-transition temperature is less than 74°C, the container is easily expanded in itself, while when the temperature is more than 100°C, the container is not expanded since the container is hard in itself.
the bottom region thereof is little drawn, so that the bottom region is provided with a lower strength as compared with other regions, and thus, it causes the result that the bottom region having a lower pressure-resistant property is exploded.
a high molecular compound having the abovementioned glass-transition temperature can be properly selected and employed.
polycarbonate, poly(ethylene naphthalate), polysulfone, polyethersulfone, a mixture of polyethyleneterephthalate (PET) and polyarylate (PAr) and the like can be exemplified.
PET polyethyleneterephthalate
PAr polyarylate
it is the mixture of PET and PAr, wherein a mixture ratio of PET to PAr by weight % is preferably 60:40 to 95:5, more preferably 80: 20 to 95:5 by weight %.
a biaxial stretching blow-molding hot-parison method comprises feeding a parison obtained through an injection molding while its hot state, to a reheating process without staying, followed by forming and thereafter, mechanically drawing the parison in a longitudinal direction while the parison is maintained at a constant temperature in a blow-die; and at the same time or in succession, blowing a pressed air into the blow-die so as to expand the parison in a circular direction (or in a transverse direction).
an aerosol container which comprises forming the engaged region of the valve cap on the periphery of the opening according to a non-stretching injection molding; and forming a body of the container which is filled with contents, according to a stretch blow-molding.
a stretch blow-molding the longitudinal drawing of the body and the transverse drawing thereof are controlled to a low stretch ratio of 1.00 to 1.15 times and 1.90 to 2.20 times, respectively, and thereby, the container can be deformed and expanded under a high pressure following a temperature elevation of the contents and thus, the thickness thereof can be thinned so as to lower the internal pressure.
an aerosol container of the present invention can be filled with, conventionally known ones can be employed.
contents for example, human-body articles, domestic articles, industrial articles can be exemplified.
human-body articles there are hair articles, cosmetics, odor-removing/sweat-repressing agents and other human-body articles;
domestic articles there are insecticides, coating agents, cleaners, foods and other domestic articles;
industrial articles there are automobile articles and other industrial articles.
hairsetting sprays As for the above-mentioned hair articles, there are hairsetting sprays, hairdressing conditioners, hair shampoos, rinses, acid wool-dyeing agents, oxidizing two-agent type permanent wool-dyeing agents, color sprays, decoloring agents, permanent-wave agents, hair-growing agents and the like.
cosmetics there are shaving creams, aftershave lotions, perfumes, eau de Cologne, face-cleansing agents, anti-suntan agents, foundations, dehairing/decoloring agents, bath agents, dentifrice agents and the like.
odor-removing/sweat-repressing agents there are odor-removing agents, sweat-repressing agents, body shampoos and the like.
muscle-antiflash agents As other human-body articles, there are muscle-antiflash agents, skin-trouble agents, medicines for a dermatophytosis, other medicines, injurious-insect repellents, cooling agents, cleaning-wiping agents, agents for oral-cavity and the like.
insecticides ther are space insecticides, insecticides for a cockroach, gardening insecticides, insecticides for a tick, insecticides for an uncomfortable insect and the like.
coating agents there are domestic paints, automobile paints, undercoating agents and the like.
cleaners there are domestic cleaners for glass, lens cleaners, carpet cleaners, bath cleaners, lustering cleaners for a floor/furniture, shoe/leather cleaners, wax lustering agents and the like.
domestic cleaners there are indoor odor-removing agents, toilet odor-removing agents, waterproofing agents, washing starches, herbicides, clothing insecticides, flameproofing agents and the like.
ther are defogging agents, thawing agents, engine-starting agents, puncture-repairing agents, engine cleaners and the like.
ther are lubricating/anti corrosive agents, adhesive agents, metal deep-cut agents, mold releasing agents and the like.
a liquid, a fluid state, a semi-solid state, a foam state, a gaseous state, as well as a mixture of each of the above-mentioned states and a little solid in a powder state or a particle state, and the like can be properly selected and employed.
the above-mentioned contents can include a material which has been conventionally employed as an additive agent.
an additive agent a material which has been conventionally employed as an additive agent.
an additive agent alcohol; a synthetic resin; a propellant (a simple substance selected from the group consisting of LPG (liquefied petroleum gas), DME (dimethyl ether), N 2 CO 2 and the like, or a mixture thereof); cellulose; ammonium; water; perfumes; dyes; surface active agents; pigments are properly selected and added thereto.
some of the above-mentioned hair sprays include a denatured alcohol and LPG for the propellant as main components, to which an acrylic resin alkanolamine liquid, polyoxyethyleneoleyl ether, a perfume and the like are added, while some of the above-mentioned hair treatments include the denatured alcohol and LPG for the propellant as main components, to which a liquid paraffin, propylene glycol, methylphenyl polysiloxane and a perfume are added.
An aerosol container shown in Figure 1 has a content volume of 97ml and a weight of 30g, wherein reference numeral (10) is an opening of the aerosol container, which is an engagement region for engaging a valve cap (which is not shown in Figure 1), and reference numeral (11) is a body for retaining contents therein.
the aerosol containers were formed according to a biaxial stretching blow-molding hot-parison method, after mixing PET and PAr in mixing ratios as shown in Table 1.
a preheating temperature of 140 °C to 165°C and a heating time of 20 seconds were employed at a heating position, while a blow-die temperature of 20°C, a blow-pressure of 20 to 35kgf/cm 2 and a blow-time of 10 to 15 seconds were employed at a stretching position.
the stretch ratio of the body of each of bottles were 1.1 times in the longitudinal direction and 2.0 times in the transverse direction.
each of the aerosol containers was filled with contents and an aqueous solution containing LPG (liquefied petroleum gas) under the conditions of an ordinary temperature (about 25°C) and an internal pressure of 6kg/cm 2 and then, a valve cap as shown in Figure 2 was fitted into the opening.
LPG liquefied petroleum gas
an environmental temperature was elevated from an ordinary temperature (about 25 °C)
the temperature of 80°C was maintained for a period of eight hours, and then it was visually evaluated whether an engagement region which is positioned on the periphery of the opening of each of the aerosol containers had been broken or not.
composition of contents used here are as follows: ⁇ Hair Spray ⁇ Weight% Acrylic Resin Alkanolamine Liquid (3%) 4.00 Polyoxyethyleneoleyl Ether 0.01 Triethanolamine 0.50 Perfume 0.17 Denatured Ethyl Alcohol of 99% 55.32 LPG 40.00 100.00 PET wt.% PAr wt.% Glass Transition Temperature Evaluation at Temperature Elevated to 80°C Comparative Examples 1 100 0 73 Engagement Region was Broken at 75°C in Middle of Elevation Working Examples 1 95 5 75 Not Broken 2 88 12 78 Not Broken 3 80 20 81 Not Broken 4 68 32 88 Not Broken 5 60 40 95 Not Broken Comparative Examples 2 50 50 102 Occurrence of Burst at Container Bottom
Aerosol containers which were produced in the same mixing ratios as the ones in the Comparative Example 1 and Working Example 1 were filled with the same contents under an internal pressure of 6kg/cm 2 , respectively, and the environmental temperature was elevated. At this time, the temperature of vapor phase in the aerosol containers, the temperature of liquid-phase in the aerosol containers, the internal pressure in the aerosol containers, and the visual evaluation as to whether the engagement regions were broken are shown in Table 2.
the engagement region was not broken by using a aerosol container-forming raw material composed of a mixture of polyarylate with polyethylene terephthalate, even if a vapor-phase temperature is 71°C, and an internal pressure is in the range of 12 to 13kg/cm 2 . This is, because the container was expanded in itself, and its thickness was thinned, and thereby, the internal pressure was decreased.
aerosol container in which a valve cap is fitted into an opening of the container is produced to have a glass transition temperature of a raw material of the aerosol container in the range of 74 °C to 100°C, and thereby, such an effect that the aerosol container in itself maintains a high pressure resistance, while even if the internal pressure of the aerosol container is increased, the valve cap or the contents there of are not explosively scattered out of the container can be provided.
