摘要： A method of injection moulding a plastics material opening device (26; 126; 226) in a hole provided in a packaging sheet material (8) including mutually arranging a first mould tool (2; 102; 202) and a second mould tool (4; 104; 204) so as to form a mould cavity in which the hole edge (12) is arranged and so as to bias a sheet portion (8a) of the packaging sheet material arranged adjacent the hole edge away from the second mould tool, and injecting heated thermoplastics material into the mould cavity so as to form the plastics material opening device. The biasing of the sheet portion away from the second mould tool aids in the formation of plastics material on the side of the sheet portion disposed towards the second mould tool, for providing a controlled placement of the opening device at the sheet hole.

摘要： The disclosure relates to a packaging container and a method of producing a packaging container for liquid contents. The packaging container has a casing (2) produced from a web-shaped multilayer material and in the form of a sleeve, which, at one end, is connected to a bottom portion (4) and at the other end is connected to a top portion (3) produced from blow moulded thermoplastic material. The casing (2) is formed by winding of the multilayer material into sleeve form and liquid-tight sealing of the material edges to a joint seam (9) extending longitudinally of the sleeve, the top portion (3) being manufactured in that thermoplastic material is extruded to form a hose (15) which is blow moulded into continuous top portions which are separated from one another and connected to the sleeveeaux.

摘要： A reducible volume container (12) includes a package wall having an interior surface and an exterior surface with at least one tear strip (16) formed in the package wall. The tear strip is defined by a pair of generally parallel frangible tear lines. Each tear line includes a pair of generally parallel creases formed on the interior surface of the package wall and a linear cut formed in the exterior of the package wall. The linear cut is disposed in an area between the parallel creases and has a depth extending only partly through the thickness of the package wall.

摘要： The disclosure relates to a laminated packaging material (10) for liquid-tight, dimensionally stable packages possessing superior gas-barrier properties, in particular oxygen gas barrier properties. The packaging material comprises a core layer (11) of paper or paperboard and outer, liquid-tight plastic coatings (12, 13) preferably of polyethylene. Between the core layer (11) and the one outer, liquid-tight plastic coating (12) of the laminated packaging material (10), there is applied, by a coating process, a gas barrier layer (14) of polyvinyl alcohol, which, for the purposes of rendering the polyvinyl alcohol layer (14) pliable and water-resistant, also includes a polysaccharide, for example chitosan, and a chemical cross-linking agent.

摘要： In the manufacture of packaging containers, for example blown plastic bottles, a circular material blank is, in certain cases, fixedly welded to the end of a sleeve-shaped casing portion. It is advantageous from amongst other energy viewpoint if the welding can take place using ultrasound, but in this instance it has been proved that the central region to the circular blank absorbs ultrasonic energy to such an extent that it is deformed or breaks. A method of using ultrasound to fixedly weld a circular material blank (13) without such drawbacks occurring is proposed according to the present invention in that the oscillations caused by the ultrasound are reduced by a mechanical stabilisation of the central region of the circular blank (13), which is put into effect with the aid of a vacuum and a relief pattern (18) provided in the central region of the circular blank. An apparatus for employing ultrasound to fixedly weld a circular material blank (13) in place displays a counter abutment (12) with a work surface for fixedly retaining the circular material blank, the work surface forming a part of a vacuum chamber, and support means for the central region of the circular blank during the welding cycle.
摘要翻译：在包装容器的制造中，例如吹塑塑料瓶，在某些情况下，圆形材料坯料固定地焊接到套筒形壳体部分的端部。如果焊接可以使用超声波发生，则其他能量观点是有利的，但是在这种情况下，已经证明圆形坯料的中心区域将超声能量吸收到其变形或断裂的程度。根据本发明，提出了一种使用超声波固定焊接圆形材料坯料（13）的方法，因为通过圆形坯料（13）的中心区域的机械稳定性降低了由超声造成的振荡），其借助于设置在圆形坯料的中心区域中的真空和浮雕图案（18）来实现。一种使用超声波将圆形材料坯料（13）固定焊接在适当位置的装置显示了具有用于固定保持圆形材料坯料的工作表面的对接基台（12），形成真空室的一部分的工作表面和支撑装置对于焊接周期中的圆形坯料的中心区域。

摘要： The disclosure relates to a drinking straw for packaging containers of the type which contains a consumer-ready portion of, for example, juice or other beverage, and is often provided with an exteriorly applied drinking straw. The drinking straw is collapsible or compressible so as to take up little space on the packaging container wall and, prior to consumption of the contents of the package, the consumer has to manipulate the drinking straw so that it attains the lenght requisite for use. One method of storing the drinking straw which saves considerable space is to utilize a drinking straw which consists of two tubular sections (2, 3) with interconnecting end portions (4, 5). By using two tubular sections of the same diameter which are provided with specifically interconnecting end portions, the design and construction of the drinking straw will be rendered considerably cheaper and simpler. The interconnecting end portions (4, 5) display an area of reduced diameter and an outwardly flared portion, respectively, these being readily brought into frictional engagement with one another by the consumer.
摘要翻译：本公开涉及一种用于包装容器的饮用吸管，其包含例如果汁或其它饮料的消费者就绪部分，并且通常设置有外部施用的吸管。吸管是可折叠的或可压缩的，以便在包装容器壁上占据很小的空间，并且在消费包装内容物之前，消费者必须操纵吸管，使其达到使用的长度要求。储存可吸收空间的吸管的一种方法是利用由具有互连端部（4,5）的两个管状部分（2,3）组成的吸管。通过使用具有特定相互连接的端部的相同直径的两个管状部分，吸管的设计和结构将变得相当便宜和简单。相互连接的端部（4,5）分别显示直径减小的区域和向外扩张的部分，这些部分容易被消费者彼此摩擦接合。
