Abstract
The present invention relates to a plastic preform suitable for stretch blow molding to form an aerosol container (20) or to an injection stretch blow molded aerosol container (20), wherein the preform or container is made of a polymeric material comprising a copolyester comprising at least 1 mole% isosorbide as comonomer and having an intrinsic viscosity of at least 0.7 dL/g.
Description
Technical field
The present invention relates to the aerosol container of Novel injection stretch-blow and applicable stretch-blow to form the novel plastic preform of aerosol container. The present invention also relates to the novel aerosol plastic dispenser for distributing aerosol or other similar pressurized product.
Prior art
Aerosol dispenser is known in this area. More specifically, aerosol dispenser comprises aerosol container, and described aerosol container comprises aerosol (or other similar pressurized product), and is equipped with the valve distribution device for distributing aerosol. The aerosol dispenser comprising the aerosol container being made of plastics such as is disclosed in U.S. Patent application US2004/0149781 and PCT application WO2007/140407.
Term used herein " aerosol " comprises aerosol according to literal meaning, and also comprising other can the product that maybe can flow from the liquid that pressurizing vessel distributes of the mode similar with aerosolization product. The product that other liquid such maybe can flow includes but not limited to foam or gel preparation, or sends from pressurizing vessel but need not be the liquid product of powder-form.
The example of typical case's aerosol composition can significantly but not exhaustivelyly for sterilant, wormer, hair jelly, cosmetic spray, air freshener, detergent, agent of shaving comprise foam and gel.
When plastic containers are for the preparation of aerosol container, the high interior pressure of plastic containers inside can cause the mechanical deformation of plastic aerosol container unfavorablely, and even causes aerosol plastic containers to explode. When this problem of mechanical deformation gentle sol plastic container explosion under the impact pressed in high has the aesthetics with concave side walls grip portions and ergonomic shape when container even more crucial, described container as such as in Fig. 1 or 2 of U.S. Patent application US2004/0149781 or such as PCT application WO2007/140407 Fig. 1,5, the container described in 6B, 6C, 7A to 7F, 8A, 8D, 8E, 8G, 8H. And have with straight sidewall or with compared with the container of the cylinder of convex sidewall, described concave side walls grip portions in fact press in high under easier mechanical deformation.
This be why aerosol plastic containers must withstand voltage with bear high in the reason of pressure. More specifically, at present in the European Community, plastic aerosol divider must meet the technical requirements of the standard FEA621 in March, 2007, and described standard FEA621 meets the regulation of the aerosol dispenser instruction 75/324/EEC in May, 1975 and relates to the measurement of the anti-interior pressure property of the empty receptacle not having valve.
PET (polyethylene terephthalate) is extensively for the preparation of two-way stretch container, more specifically prepares the polyester known of injection drawing blow (ISBM) container.ISBM level PET has the limiting viscosity (IV) of 0.7dL/g to 0.8dL/g and the second-order transition temperature (Tg) of about 75 DEG C to 80 DEG C usually.
Usually, polyester, such as PET homopolymer or multipolymer, in the region more than the natural draw ratio (NSR) of polymkeric substance, when can advantageously show the crystallization of strain inducing when a large amount of orientation. It is well known that, for obtaining the ISBM polyester container with good mechanical properties, the two-way stretch of polyester must be enough important in the strain hardening region of polyester, only slight beyond the NSR of polymkeric substance.
The NSR of polymkeric substance can measure with being familiar with in free blowing is tested. The free blowing of thermoplastics, particularly PET and PET copolymer is the technology known of the rule of thumb data of the stretch behavior for obtaining concrete resin formula. The method of free blowing PET preform is described in " blowing handbook (BlowMoldingHandbook) " that edited in 1989 by DonaldV.Rosato, DominickV.Rosato, Munich. Term " free blowing " refers to the blowing preform when not using mould. Relate to, from preform free blowing bottle, the temperature that preform is heated to more than its second-order transition temperature, then make preform expand at mold exterior, so that its free expansion without limitation, until strain hardening starts. Strain hardening can be detected as the stress following flowing level ground in stress-strain curve and rise. To a great extent, strain hardening is relevant to the molecular assembly process in resin. If the blowing pressure of preform and heating given preform is suitably arranged, then its by continuations expand, until all PET be oriented stretch by near natural draw ratio or slightly exceed natural draw ratio place stopping point.
But, standard I SBM level PET, even if in strain hardening region, usually it is not suitable for the withstand voltage ISBM aerosol container that preparation stands high interior pressure, more generally it is not suitable for the withstand voltage ISBM aerosol container preparing the technical requirements by the standard FEA621 realizing in March, 2007.
Structure the following glycol 1,4:3,6-bis-illustrated dewater-D-glucitol (hereinafter referred to as Isosorbide) easily prepared by renewable resources, such as sugar and starch, the native starch particularly extracted from corn, wheat, potato and pea. Such as, Isosorbide can by the hydrogenation of D-Glucose then acid-catalyzed dehydration preparation.
Isosorbide has been used as and has been incorporated into polyester such as the monomer in PET with low-level. Known Isosorbide mixes the limiting viscosity reducing copolyesters in copolyesters as comonomer.
Therefore, comprise the copolyesters of Isosorbide, particularly comprise the polyethylene terephthalate (PEIT) of isosorbide polymer, and it is known in this area by melt polymerization or by the preparation method of solvent polymeric.
