    • An all purpose cleaner for hard surfaces comprises an aqueous solution of a secondary alcohol ethoxylate surfactant, an alkylpolyglycoside surfactant, and water, optionally comprising a chelating agent and sufficient pH modification agent to provide an alkaline solution. The ethoxylate surfactants preferably have HLB values of from 12.2 to 14.6, and each surfactant may comprise up to about 5 weight percent of the solution. The solution may be essentially free of organic solvents, such as alkylene glycol or alkylene glycol ethers, or other volatile organic compounds. As a result, the solution may be fragrance free, and, if so desired, colorless. Optionally, however, the cleaning solution may contain fragrances, coloring agents, anti-bacterials, stabilizers, preservatives, and other constituents, including a minor amount of a co-surfactant.
    • 用于硬表面的全能清洁剂包括仲醇乙氧基化物表面活性剂的水溶液,烷基多糖苷表面活性剂和水,任选地包含螯合剂和足够的pH改性剂以提供碱性溶液。 乙氧基化物表面活性剂优选具有12​​.2至14.6的HLB值,并且每个表面活性剂可包含至多约5重量%的溶液。 该溶液可以基本上不含有机溶剂,例如亚烷基二醇或亚烷基二醇醚或其它挥发性有机化合物。 结果,溶液可以是无香料的,如果需要,则为无色的。 然而,任选地,清洁溶液可以含有香料,着色剂,抗菌剂,稳定剂,防腐剂和其它成分,包括少量的辅助表面活性剂。

    • Methods for forming rib and groove plastic fastener elements and for securing them to a film web are provided. The rib element, as extruded, has an arrowhead-shaped tip, a concave tail, and a generally upstanding stem portion connecting the tip and tail. The groove element is formed having a base with a pair of generally upstanding neck elements disposed on opposite ends of the base. The base does not extend beyond the neck elements. The rib and groove elements are readily secured to the film web without entrapment of air between the elements and film web. Reclosable plastic containers may be formed utilizing the disclosed rib and groove elements.
    • 提供了用于形成肋和凹槽塑料紧固件并将其固定到薄膜网的方法。 肋元件,如挤出的,具有箭头形尖端,凹形尾部和连接尖端和尾部的通常直立的杆部分。 凹槽元件形成为具有基部,其具有设置在基部的相对端上的一对大致直立的颈部元件。 基部不延伸超过颈部元件。 肋和沟槽元件容易地固定到膜片上,而不会在元件和膜片之间夹带空气。 可以利用所公开的肋和槽元件形成可再闭合的塑料容器。
