硬质包装容器（瓶,罐）的有序造型设计

根据材质和成型特点,包装容器可分二大类:1.软质包装容器;2.硬质包装容器。软质包装容器主要以质地软,形变性大的纸质材料,软塑材料(塑膜、塑纸、复合膜、吸塑),纺织材料,编织材料等制作的盒、箱、袋、托盘等包装容器。硬质包装容器主要以玻、陶、塑、金属为原材料,通过模具热成型工艺和加工制成的瓶、罐、盒、箱等。这类包装成型后硬度强,不易变形、不透气、不渗水、化学稳定性好,被大量用在包装酒、饮料、药品、化妆品、化工产品、食品等各类液态、膏体、粉状、     

PET瓶面临发展新机遇

基于SolidWorks的中空塑料包装容器耐内压强度有限元分析

目的研究在不同壁厚、不同直径条件下,中空塑料包装容器承载内压强度的能力。方法主要通过Solid Works软件设计出了不同壁厚、不同直径和不同结构的包装容器3D模型,然后进行了有限元分析。结果通过多次试验和数据处理,得出了塑料包装容器承载内压强的能力与包装瓶壁厚、直径之间的关系公式。结论经过测试发现在碳酸饮料灌装压力0.5 MPa的条件下,包装容器壁厚至少要大于1.5 mm,瓶体才不会破裂,测试结果也为今后中空塑料包装容器的设计提供了一定的参考。

液体物料定量灌装机常见故障及处理

定量灌装机是通过控制充填到包装容器内的液体容积进行计量和灌装的机器,其分注液量准确、液量调整方便,是测量液体定量包装产品不可或缺的小容量计量设备。本文对液体物料定量灌装机可能出现的故障及处理分析如下：1.灌装液体的温度变化会影响灌装量。由于液体体积随温度升高而变大,随温度降低而变小,所以灌装时虽然容积没变,但质量变了,造成灌装质量误差。     

称重式液体灌装机发展前景分析

一、过去灌装机械的概况所谓灌装机械,通常是指将液体产品充填到包装容器内的机器。而灌装生产线则指实现产品从原料进入包装设备开始,经过加工、输送、装配、检验等一系列生产活动所构成的路线。灌装生产线具有较大的灵活性,可广泛应用于多种产品的生产加工。但过去由于技术水平的局限,灌装生产线系统存在不少缺点,例如采购成本昂贵、设备体积大、安装难度大、维修费     

旋转型灌装机运动方案设计

旋转灌装机在转动工作台上对包装容器(如玻璃瓶)连续灌装流体(如饮料、酒、冷霜等),转台有多工位停歇,以实现灌装、封口等工序。所以应采用灌瓶泵灌装流体,并且使泵固定在某工位的上方。采用软木塞或金属冠盖封口,它们可由气泵吸附在压盖机构上,由压盖机构压入(或通过压盖模将瓶盖紧固在)瓶口。压盖机构可采用移动导杆机构等平面连杆机构或凸轮机构。此外,需要设计间歇传动机构,以实现工作转台间歇传动。为保证停歇可靠,还应有定位(锁紧)机构。     

口服固体制剂常用包装材料及容器的研究进展

目的 为不同口服固体制剂准确选用合适包装容器提供理论参考和现实依据。方法 从口服固体制剂常用包装容器的原材料和辅料特性入手,通过解析不同包装容器的技术要求,介绍国内药品包材审评制度和现阶段国家药监局药品审评中心药用包装材料登记数据,对口服固体制剂不同包装容器的特点和使用进展进行综述。结果 对剂量要求精准、单日服用剂量较小的制剂宜选用单剂量独立包装的泡罩包装;对需长期用药、单日服用剂量较大的药物宜选用塑料瓶包装;颗粒剂和散剂多选用复合膜、袋包装;包装规格较大但不宜用塑料瓶包装的芳香性、油脂性、挥发性及易氧化药物,可选用玻璃瓶包装。结论 药品生产企业在选择药品包装时,应结合包装原材料物化性质、与承装药品相容性、力学性能、装量范围、携带使用方便性和价格成本等多方面因素,综合考虑选择合适的包装容器,以保证药品质量稳定和安全有效。     

物流过程对包装的影响

流通过程对包装质量的影响不光取决于包装容器的生产,在使用、防护、搬运、储存等流通过程中也将直接受到影响,这些因素在实际中往往被人们所忽视。一.包装在使用中存在的问题1.灌装内装物在灌装内装物时,有不少人认为装得越多越好,忽视了包装内装物的膨胀系数。如某外贸公司出口     

Critical Factors in Opening Pharmaceutical Packages: a Usability Study among Healthcare Workers,Women with Rheumatoid Arthritis and Elderly Women

This cross‐sectional study compared the usability of pharmaceutical packages to determine the critical factors involved in packages with different opening mechanisms. Four packaging types (a bottle with a screw cap, a box with a pill plate, disposable plastic droppers with a container and a jar with a hinge cap) were evaluated by 45 women (nurses, older women and women with rheumatoid arthritis). Usability was evaluated for subjective measures related to the ease of opening and for objective measures related to the time needed to open the packaging, electrical muscular activity (electromyography, EMG) and ranges of motion of the upper extremities. Of the arthritic women, 13% were unable to open the screw‐cap bottle, and 20% did not succeed in opening the plastic dropper packaging. Everyone else, except one older woman handling the plastic dropper packaging, managed to open all the packages. Regarding the ease of opening, the participants gave the plastic dropper packaging the lowest rating (p < 0.001). The arthritic women used greater relative biomechanical strain while opening the screw cap bottle and the box with pill plate compared with the other participants (p < 0.05), with the relative muscular strain in the forearm varying by 29–40% for the maximal EMG activity and the relative range of motion in the wrist being 70–90% of the maximal range of motion. These findings revealed both subjectively and objectively measured features on the usability of pharmaceutical packages. The comprehensibility of the opening mechanism and the ease of handling the package should be considered when user‐friendly products are being created. Copyright © 2013 John Wiley & Sons, Ltd.     

Quality of orange juice in barrier packaging material

The vitamin C content and the colour of orange juice made from concentrate were measured during 9 months of storage at 20°C either under artificial light or in darkness. The packaging materials used were glass, standard monolayer polyethylene terephthalate (PET) and multilayer PET (PET/nylon and oxygen scavenger/PET) containers. In this experiment, all bottles were sealed with aluminium foil in order to avoid any cap effect. The results showed that in plastic packaging materials, the loss of vitamin C was related to the oxygen permeability, and that glass provided the best preservation of ascorbic acid. No statistical difference (p < 0.05) was revealed between the vitamin C content in the juice stored under artificial light or in darkness, whatever the packaging used. The modification of colour was studied with the L, a* and b* values during storage at 20°C under artificial light. L and b* decreased, revealing a reduction of lightness and yellow colour of the juice, whereas a* increased, due to the formation of brown pigments. This change in colour was partly related to the oxygen permeability of the packaging used. The losses of aroma compounds by permeation through the bottle (PET) and the cap (high‐density polyethylene, HDPE) have also been investigated. The results showed that permeation mainly took place through the cap. The use of a multilayer cap [HDPE with internal barrier layer of low‐density polyethylene (LDPE)/EvOH/LDPE] considerably limited the permeation of the aroma compounds studied, whatever the PET bottle used.

目的改善文房四宝包装形式单一和与需求不同步的现象。方法用可调节长度的多孔塑料筒包装替代竹制笔帘,减少墨汁瓶注入口数量,将两个注入口简化为一个。将宣纸的纸质简包装改为秸秆制作的环保板材包装盒,将携行状态下的砚台的塑料袋包装改为橡胶密封圈和橡胶皮套组合包装。结果保留了竹笔帘包装透气的优点,杜绝了毛笔从笔帘中滑落的现象,减少了对生态资源的依赖。墨汁瓶口设计的渗漏可能性极低,提高了携行可靠性。宣纸包装盒简化了取放程序,增加了防潮、防虫功能,还能重复利用,并将秸秆变废为宝,创新了砚台携行包装形式。结论长期以来传统文具包装忽略了创新和与消费层面的沟通,观念守旧产品更新迟滞。文房四宝传统文具的包装要顺应时代的发展变化和需求,在传承的基础上创新,加强对设计人才的培养,以期改善传统文具产品包装的落后面貌。     

Warpage analysis of epoxy molded packages using viscoelastic based model

Package warpage during the cooling process just after the molding is one of the critical issues in the manufacture of plastic integrated circuit (IC) packaging. Such warpage depends on the epoxy molding compound characteristics and the dimensional details of the IC package design such as downset and the chip to die-pad area ratio. In this study, the analysis methodology using a viscoelastic based material model is adopted to account the time and temperature dependent behavior of epoxy molding compound. Using such model the effect of compound thickness ratio of the top to bottom side of the package is optimized to reduce the package warpage. Secondly, the effect of the cooling rate on the warpage is also examined in this study.
