技术领域technical field
本发明涉及一种吸头，特别是一种滴管吸头及其生产方法。The present invention relates to a suction head, in particular to a dropper suction head and a production method thereof.
背景技术Background technique
滴管吸头是化妆品滴管的主要组成部分。吸头连接吸液管，并与其放置在同一个容器内。吸头必须可挤压，以便将液体吸入吸液管中，并将吸入的液体挤出去。鉴于滴管吸头具有可挤压性，因此滴管吸头的材料必须柔软有弹性，目前现有吸头通常采用腈基丁二烯橡胶、橡胶、热塑性弹性体或丁基橡胶等材料，采用传统注塑方法制作。现有市场上的吸头所采用的材料和制作方法限制了吸头形状和颜色的多样化，使现有吸头形状简单，样式少，颜色单调，没有新意，外观效果不好。并且生产时有很大缺点是产品外观容易光合变黄。Dropper tips are the main component of cosmetic droppers. The tip is attached to the pipette and placed in the same container. The tip must be squeezable in order to draw liquid into the pipette and squeeze out the aspirated liquid. In view of the compressibility of the dropper tip, the material of the dropper tip must be soft and elastic. At present, the existing tip usually uses materials such as nitrile butadiene rubber, rubber, thermoplastic elastomer or butyl rubber. Made by traditional injection molding method. The materials and manufacturing methods used in the existing suction heads on the market limit the diversification of the shapes and colors of the suction heads, so that the existing suction heads have simple shapes, few styles, monotonous colors, no novelty, and poor appearance. And there is a big disadvantage in production that the appearance of the product is easy to photosynthetically turn yellow.

该生产方法是采用注吹一体机实现的，即一步法注吹成型。The production method is realized by an integrated injection-blow molding machine, that is, one-step injection-blow molding.
该生产方法是采用注塑机和吹塑机实现的，即两步法注吹成型。The production method is realized using an injection molding machine and a blow molding machine, namely two-step injection blow molding.
在上述方案的基础上，本发明还做了如下改进：On the basis of the above scheme, the present invention has also made the following improvements:
本发明具有的优点和积极效果是：通过采用离子键树脂以及注吹成型技术制作滴管吸头，利用离子键树脂在加工温度下具有良好加工流动性的特点，可获得形状复杂多样的产品，利用离子键树脂粘合力好的特点，可获得多种颜色的产品，因此，采用本发明的滴管吸头可具有多种形状和多种颜色，满足化妆品行业对美观包装的需求，有利于化妆品行业的发展。并且采用本发明的滴管吸头透明性好，具有优良的橡胶弹性和柔韧性，低温性能优良，拉伸强度优于聚乙烯，耐环境应力开裂性、耐油性优越，不易老化变黄。此外，离子键树脂的耐化学性能高于腈基丁二烯橡胶、橡胶、热塑性弹性体或丁基橡胶等材料，因此，采用本发明的滴管吸头能够应用于传统滴管材料无法兼容的液体，可用于制药行业，促进制药行业的发展，能够适用的液体范围更广。The advantages and positive effects of the present invention are: by using the ionomer resin and injection blow molding technology to make the dropper tip, the ionomer resin has the characteristics of good processing fluidity at the processing temperature, and products with complex and diverse shapes can be obtained, Utilizing the good adhesion of the ionomer resin, products of various colors can be obtained. Therefore, the dropper tip of the present invention can have various shapes and colors, which can meet the needs of the cosmetic industry for beautiful packaging, and is beneficial to Development of the cosmetic industry. In addition, the dropper tip of the invention has good transparency, excellent rubber elasticity and flexibility, excellent low temperature performance, better tensile strength than polyethylene, superior environmental stress cracking resistance and oil resistance, and is not easy to age and turn yellow. In addition, the chemical resistance of the ionomer resin is higher than that of materials such as nitrile butadiene rubber, rubber, thermoplastic elastomer or butyl rubber. Therefore, the dropper tip using the present invention can be applied to materials that are incompatible with traditional dropper materials. Liquid, can be used in the pharmaceutical industry, promote the development of the pharmaceutical industry, and can be applied to a wider range of liquids.
