摘要:
A cap adapted for use as a container cover where the cap has a thermoplastic resin liner pressed formed onto the inner surface of a cap shell. The plastic liner is formed such that the difference between the intrasurface orientation index of the outer peripheral portion of the liner and the intrasurface orientation index of the central portion of the liner does not exceed 0.37 where the intrasurface orientation index is defined as the sum of the orientation coefficient of the liner in the radial direction and the orientation coefficient of the liner in the circular direction.A method of making a cap having a thermoplastic liner where the liner is press-formed into shape under conditions whereby the difference between the intrasurface orientation index of the outer peripheral portion of the liner and the orientation index of the central portion of the liner does not exceed 0.37.
摘要:
Container closure having an easily openable liner, said liner being composed of a composition comprising a base resin consisting of 95 to 30% by weight of a crystalline polyolefin and 5 to 70% by weight of a lowly crystalline or amorphous copolymer of ethylene with otherolefin, a lubricant in an amount of 0.001 to 5% by weight based on said base resin and a polymer containing at least 10% by weight of a conjugated diene in an amount of 1 to 15% by weight based on said base resin. This closure has a good sealing property and an easy openability in combination.

Disclosed is a bottle for a carbonated drink, which is formed by biaxial draw-blow molding of a polyester containing a surface active agent and being composed mainly of ethylene terephthalate units, wherein at least the barrel wall portion of the bottle is molecularly oriented biaxially so that the density is at least 1.34 g/cm.sup.3 as measured at 20.degree. C., and the surface active agent is distributed in the surface of the barrel wall portion so that the contact angle of the surface of the barrel wall portion to water is not larger than 76.degree..In this bottle, the speed of transfer of carbon dioxide gas from the liquid phase of the drink to the gas phase at the time of opening the bottle is controlled to a very low level. Accordingly, occurrence of the cap missile phenomenon at the time of removing the cap from the bottle or reduction of the carbon dioxide content in the drink at the time of repeating sealing and opening of the bottle can effectively be prevented.
摘要翻译:公开了一种碳酸饮料瓶,其通过双轴拉伸吹塑成型含有表面活性剂的聚酯而形成,主要由对苯二甲酸乙二醇酯单元组成,其中瓶的至少筒壁部分分子取向为双轴向 密度在20℃下测定为至少1.34g / cm 3,表面活性剂分布在筒壁部分的表面,使得筒壁部分的表面与水的接触角不是 大于76度。 在该瓶中,将饮料液相中的二氧化碳气体向打开瓶子时的气相转移速度控制在非常低的水平。 因此,可以有效地防止在重复密封和打开瓶子时从瓶子上取下帽子或者饮料中二氧化碳含量的降低时发生帽子导弹现象。
摘要:
A process for manufacturing a closure cap having a liner. A mass of molten thermoplastic is positioned in the inner face of a cap shell. The mass is spread by a heated punch and the spread mass is then formed by a cooled punch to the final liner shape.
摘要:
A movable discharge device for use in a particle/bulk material storage silo includes: a travel body configured to travel along a groove provided at a lower portion of a storage silo; a scrape-out unit configured to move integrally with the travel body and including a blade configured to rotate above the groove to rake coals in the storage silo and scrape out the coals to the groove; and a groove closing mechanism configured to close a predetermined region of the groove within a rotation trajectory region of the blade. The discharge device is configured to be able to suppress the change in the discharge amount of coals discharged by the blade from the particle/bulk material storage silo.

There is provided the novel compound 11-hydroxypregn-4-en-3-one-20-carbaldehyde, as well as a microbial method for production of the same. This novel compound is of value as a starting material for antiinflammatory corticoids such as hydrocortisone, cortisone, prednisolone and prednisone.
摘要:
A peelable adhesive structure is disclosed which comprises a plurality of parts at least one of which is made of metal, adhering together by means of a coating, characterized in that said coating has a peelable surface formed between a first layer of a denatured hydrocarbon resin or denatured hydrocarbon resin composition having an acid value of from 0.1 to 20 and a second layer containing an epoxy resin.

A peelable bonded structure having a peel strength of 0.05 to 5 kg/cm comprises a plurality of articles, at least one of which is made of metal, bonded together through a composite coating layer. The composite coating layer is composed of adjacent first and second coating layers at least one of which comprises (A) a modified olefin resin having a carbonyl group concentration of 0.01 to 200 milliequivalents per 100 g of the olefin resin and (B) a coating film-forming base resin at an (A)/(B) weight ratio of from 0.2/99.8 to 40/60 and has a multi-layer distribution structure having resin concentration gradients in the thickness direction such that the modified olefin resin (A) is distributed predominantly in the portion contiguous to the interface between the two coating layers and the base resin (B) is distributed predominantly in the opposite portion.

A bimetal is disclosed having a high, rapid deflection over a specified temperature range, including a high expansion metal alloy component having a high thermal expansion coefficient that changes rapidly at 50.times.10.sup.-6 /.degree. C. or greater at a temperature of between about 100.degree. C. and 250.degree. C. and containing from 15-30% by weight of manganese, the balance of iron. The second component has a substantially constant thermal expansion coefficient regardless of the temperature change, and is preferably a stainless steel. These bimetals are used in circuit breakers, thermal protectors and the like.
摘要:
When 1-halogeno-3-alkene-2-ol is reacted with an ortho-carboxylic ester and/or a ketene acetal, a .gamma.-halogeno-.delta.-unsaturated-carboxylic ester is obtained as a main reaction product. When this intermediate is treated with a basic substance, a substituted cyclopropane-carboxylic ester is formed. This ester can be used as an insecticide or an agricultural chemical as it is or after the alcohol residue of the ester has been converted to other alcohol residue.
