In FIG. 2, four stacked paperboard

In FIG. 2, four stacked paperboard cups according to the paperboard cup in FIG. 1 are shown. An area X is marked in this Figure, which is shown in FIGS. 3 and 4 in enlarged dimensions. In the embodiment chosen in FIG. 2, the paperboard cups do not possess an upper shoulder 8, which renders the insulating properties of these paperboard cups slightly less effective, in comparison to the paperboard cup according to FIG. 1. The degree of insulation of the paperboard cup and thus its geometric form is determined in particular by the temperature of the liquid to be filled into the cup. The material thickness of the inner cup, followed by the gap between the inner cup and the outer sleeve and the thickness of the material of the outer sleeve all determine the drop in temperature between the drink in the cup and the hand holding it. The mass per unit area of the paperboard of the inner and outer sleeves amounts, as a rule, to several hundred grammes per square metre; in the case of coffee cups, a paperboard having 350 g/m2 is often used. The paperboard of the inner cup is polyethylene-coated, whereby the mass per unit area of the coating lies normally in the range between 15 to 30 g/m2. The gap between the inner and outer sleeve measures approximately 1.2 mm at mid-cup height. Thus a liquid having a temperature of 80° C., which is filled into a paperboard cup according to FIG. 1, achieves an outer temperature of below 60° C., permitting the paperboard cup to be held in the hand for a longer time without causing pain. If liquids are filled in having temperatures which approximate the boiling point of water, a paperboard cup according to FIG. 2 can then deliver a sufficient insulating effect, as long as the diameter difference of the shoulder 8 measures approximately 1.2 mm.

For large paperboard cups, for instance, having a volume of 400 ml, the diameter of the cup opening 27 (FIG. 2) is so large that radial stability decreases. In particular when paperboard cups are gripped with excessive force at the shoulder-shaped stacking stopper 5, this can become so deformed that, for example, individual cups can become stuck during temporary storage. This disadvantage is eliminated by means of an inner shoulder 8, which is located in the area of the stacking shoulder. Shoulders of this type are known in German published patent appllication 198 40 841, but are only used in order to improve the general deforming of the cup opening without any particularly good stacking properties arising therefrom.

For paperboard cups of the present invention, the shoulders 8 have the capacity to stabilize the upper stopper 7, whereby the stability of the shoulder-shaped stacking stopper 5 is increased and the likelihood of the stacking stopper 5 being deformed is reduced.

FIG. 3 illustrates the excellent stacking and de-stacking properties of the paperboard cup of the present invention. Stacking of a paperboard cup is achieved by the contact 10 of the drinking lip 9 of the stacked paperboard cup and the shoulder-shaped stacking stopper 5 of the paperboard cup being stacked. The axial force F1, which, for example could act by means of pressure from above on the stacked paperboard cups and which axial force F1 is denoted in FIGS. 3 and 4 by a double arrow, is absorbed between the contact 10 of the stacking stopper 5 and the upper stopper 7 of the outer sleeve 2, which is adhered to the inner sleeve 31. As the force at the contact 10 of the stacking stopper 5 is directed normally onto the drinking lip 9, no force is generated in the direction of the inner sleeve 31, whereby no movement either of the outer sleeve 2 of the paperboard cup being stacked is generated in the direction of the inner sleeve 31, thus resulting in an extremely stable stacking design. The stability is only limited by the pressure of the drinking lip 9 of the stacked paperboard cup and by the support of the drinking lip by means of the upper stopper 14 of the outer sleeve 2. The radial increase in stability of the shoulder-shaped stacking stopper can be seen in a comparison of FIGS. 3 and 4 and comparing the action of the force F2. The force F2 is denoted by the direction of a double arrow and should act in the area of the stacking stopper 5. Due to the design of the shoulder 8, a large cylindrical area 28 to 29 is formed, which reduces the likelihood of the shoulder-shaped stacking stopper 5 being deformed because said cylindrical area 28 to 29 reduces the free-standing area of the outer sleeve 2 in the area from 29 to 30.

The FIGS. 5 and 6 illustrate the position 15 of the support of the rolled lip 6. For an economical production of the paperboard cup, the position 15 of the rolled lip 6 can be applied several millimeters above the paperboard cup bottom (see FIG. 5), whereby a saving in material of up to 20% can be achieved. If great stability is required, then the position 15 of the rolled lip should be applied to the level of the paperboard cup bottom (see FIG. 6), as then the force from gripping the cup is absorbed by the cup bottom 4.

In FIGS. 7 to 12 the essential procedural stages for applying the stacking stopper 5 with the aid of various states of the forming station 16 are shown. The forming station 16 comprises the cup take-up 18, the lower cup support 17 and the pressing arrangement 19, whereby the lower cup support 17 is not shown in FIGS. 7 and 12.

FIG. 7 shows the feeding of the outer sleeve into the cup take-up 18 of the forming station 16. The outer sleeve 2 already possesses the lower rolled lip 6, which is applied in advance procedural steps. As soon as the cup take-up is equipped with the outer sleeve 2, it is carried between the lower cup support 17 and the pressing arrangement 19. This state is shown in FIG. 8.

In order to apply the shoulder-shaped stacking stopper 5, the outer sleeve 2 is brought into the pressing arrangement 19. The lower take-up support 17 is carried so far in the direction of the pressing arrangement 19 until the outer sleeve 2 touches with its upper edge 24 the stop ring 25 of the pressing arrangement 19. The forming station is then closed. This state is shown in FIG. 9.

The pressing arrangement 19 is subsequently closed. The outer slider 23, as shown in FIG. 10, travels downwards so that it drives the outer jaws 21 radially inwards. In addition the expansion mandrel 20 travels downwards, thus driving the inner jaws 22 radially outwards. Thus the inner jaws 22 and the outer jaws 21 form the shoulder-shaped stacking stopper 5. In order that the shoulder-shaped stacking stopper is formed in the way it is shown in FIG. 3, the cup is supported by the inner cup support 26, which supports the cup cone below the stacking stopper 5. The direction of motion of the outer jaws 21, the inner jaws 22, the expander mandrel 20 and the outer slider 23 are denoted during the closing of the pressing arrangement 19 by arrows.

The next procedural step is shown in FIG. 11. The pressing arrangement 19 is again completely open. To better illustrate the opening process of the pressing arrangement 19, the direction of motion during opening of the the pressing arrangement 19 of the expansion mandrel 20, the outer jaws 21, the inner jaws 22 and the outer slider 23 are denoted by arrows. In addition, the movement of the lower cup support 17, which sets in directly after the pressing arrangement 19 is opened, is denoted by an arrow.

After the forming station 16 is opened, the cup take-up 18 can be carried to the next position (FIG. 12), where the outer sleeve 2 is equipped with the inner cup 1. The further stages for finishing the paperboard cup are not described here.

在图 2 中，列出了根据纸板杯在图 1 中的四个堆积的纸板杯。在此图中，显示在图 3 和 4 中扩大尺寸标记面积 X。在图 2 中选择的体现，纸板杯不具备上面的肩膀 8，呈现这些纸板杯稍微不那么有效，与纸板杯按图 1 绝缘性能。绝缘的纸板杯和因而其几何形态的确定程度特别是由液体的温度进杯子里填补。内杯后, 跟间隙内杯和外套筒之间的材料厚度和外套筒所有材料的厚度确定在杯中的饮料和抓着它的手之间的温度下降。每单位面积质量的内在与外在的纸板袖子的数额，作为一项规则，几个几百克每平方米;在咖啡杯，有 350 g/m2 纸板常用。纸板的内杯是聚乙烯涂层，藉以单位面积涂层的质量通常位于范围在 15 至 30 g/m2 之间。内、 外套筒措施在中期杯高度大约 1.2 毫米之间的差距。因而一种液体温度为 80 ° C，填入一纸板杯根据图 1，达到外的温度低于 60 ° C.，允许纸板杯将举行手较长时间而不会造成疼痛。如果液体都有近似的水沸点的温度，根据图 2 的纸板杯然后可以提供足够的隔热效果，只要 8 肩直径差措施约 1.2 毫米。大纸板的杯子，例如，为 400 毫升，27 (图 2) 的杯口直径具有体积如此之大，径向稳定性降低。特别是当纸板杯都笼罩在肩背形的堆叠塞子 5 过度使用武力，这会变得如此畸形，例如，临时贮藏过程中，可以成为困个人的茶杯。通过内肩 8，位于该地区的堆叠的肩膀，消除这一缺点。这种类型的肩膀在德国出版专利事宜 198 40 841，众所周知，但只用于以提高一般变形，没有任何特别好的叠加特性，由此产生的杯口。本发明的纸板杯子，肩膀 8 有能力稳定上部塞 7，藉以增加肩背形的堆叠塞子 5 的稳定性和减少堆叠塞子 5 被变形的可能性。FIG. 3 illustrates the excellent stacking and de-stacking properties of the paperboard cup of the present invention. Stacking of a paperboard cup is achieved by the contact 10 of the drinking lip 9 of the stacked paperboard cup and the shoulder-shaped stacking stopper 5 of the paperboard cup being stacked. The axial force F1, which, for example could act by means of pressure from above on the stacked paperboard cups and which axial force F1 is denoted in FIGS. 3 and 4 by a double arrow, is absorbed between the contact 10 of the stacking stopper 5 and the upper stopper 7 of the outer sleeve 2, which is adhered to the inner sleeve 31. As the force at the contact 10 of the stacking stopper 5 is directed normally onto the drinking lip 9, no force is generated in the direction of the inner sleeve 31, whereby no movement either of the outer sleeve 2 of the paperboard cup being stacked is generated in the direction of the inner sleeve 31, thus resulting in an extremely stable stacking design. The stability is only limited by the pressure of the drinking lip 9 of the stacked paperboard cup and by the support of the drinking lip by means of the upper stopper 14 of the outer sleeve 2. The radial increase in stability of the shoulder-shaped stacking stopper can be seen in a comparison of FIGS. 3 and 4 and comparing the action of the force F2. The force F2 is denoted by the direction of a double arrow and should act in the area of the stacking stopper 5. Due to the design of the shoulder 8, a large cylindrical area 28 to 29 is formed, which reduces the likelihood of the shoulder-shaped stacking stopper 5 being deformed because said cylindrical area 28 to 29 reduces the free-standing area of the outer sleeve 2 in the area from 29 to 30.图 5 和图 6 说明位置 15 卷唇 6 的支持。以纸板杯经济生产，热轧唇 6 15 的位置可用于几毫米以上纸板杯底部 (见图 5)，即可以达到节省 20%的物料。如果极大的稳定性是必需的那么热轧唇的位置 15 应适用于水平的纸板杯底部 (见图 6)，作为然后从扣人心弦杯力吸收由杯底 4。图 7 到 12 显示的基本程序性阶段申请堆叠塞子 5 与成形站 16 各国的援助。成形站 16 包括杯卷取 18，低杯支持 17 和紧迫安排 19，藉以低杯支持 17 不会显示在图 7 和 12。图 7 显示了进成形站 16 杯卷取 18 外套筒。外套筒 2 已经拥有热轧的下唇 6，即应用预先程序步骤。尽快杯卷取配备外套筒 2，它被进行低杯支架 17 和紧迫安排 19 之间。这种状态如图 8 所示。为了应用的肩背形的堆叠塞子 5 外, 套筒 2 带进紧迫安排 19。低卷取支持 17 为止进行紧迫安排 19 方向直到 2 外套筒接触它的上部边缘 24 止动环 25 的紧迫安排 19。然后关闭成形站。这种状态如图 9 所示。随后关闭压安排 19。外滑块 23，如图 10 所示旅行向下，它驱动外颚 21 径向向内。此外膨胀芯 20 旅行向下，因而驾驶内在颌骨 22 径向向外。因此内部大白鲨 22 和外颚 21 形成的肩背形的堆叠塞子 5。为了在肩背形的堆叠塞子它图 3 中所示的方式形成的杯子被受内杯支持 26，支持下面的堆叠的塞子 5 杯锥。外颚 21、 内在颌骨 22、 20 膨胀芯轴和外滑块 23 运动方向是紧迫安排 19 闭幕时由箭头表示的。接下来的程序性步骤如图 11 所示。紧迫安排 19 又是完全开放的。为了更好地说明紧迫安排 19，运动期间开放的方向开放进程紧迫安排 19 20 膨胀芯轴、 外颚 21、 内在颌骨 22 和外滑块 23 由箭头表示。此外，低杯支持 17，设置中直接打开紧迫安排 19 后，运动是由箭头表示。成形站 16 打开后，杯卷取 18 可以被运到下一个位置 (图 12)，在外套筒 2 配有内杯 1。此处没有描述的进一步整理纸板杯阶段。

在图2中，根据图四所示的纸板杯的1个堆叠的纸板杯。在这个图中有一个区域，在图中显示。4和3在放大的尺寸。在图2中选择的实施方案中，纸板杯不具有一个上肩8，这使得这些纸板杯的绝缘性能稍欠有效，根据图1与纸板杯进行比较。纸板的绝缘程度，从而其几何形式的确定，特别是由温度的液体，以填补进入杯。内杯的材料厚度，其次是内杯和外套之间的差距和外套的材料的厚度，都决定了杯里的饮料和手拿着它的温度下降。每对内、外套量纸板单位面积的质量，作为一项规则，以每平方米几百克；在咖啡杯的情况下，一种纸板有350克/平方米是常用的。内杯的纸板是聚乙烯涂层，从而使涂层的质量单位面积通常在15至30克/平方米之间的范围内。内和外套措施之间的差距约1.2毫米，中杯高度。因此，有一种液体，具有80个温度的温度，这是填充到一个纸板杯根据图1，达到低于60角的外部温度，允许纸板杯在手举行一个较长的时间，而不会引起疼痛。如果是液体填充具有温度近似的沸腾点水，纸板按图2杯就可以提供足够的保温效果，只要作为直径差肩8措施约1。2毫米，对于大的纸板杯，例如，有一个体积为400毫升，杯口直径27（图2）是如此之大，径向稳定性下降。特别是当纸板杯被过度的力量在肩膀形的堆积器5，这可以成为如此变形，例如，个别杯子可以成为暂时储存卡。
