Description

包装设备及方法
技术领域
本发明涉及一种用于包装物品的包装设备和包装物品，例如包装一包香烟、小雪茄烟、雪茄烟等的方法，在这里为清楚、简洁起见，它们将被统称为“吸烟物品(smokingarticle)”。本发明还涉及一种通过所述装置和方法生产的包装后的物品，例如一包吸烟物品。
背景技术
一包吸烟物品，例如一包香烟，通常在包装过程中生产，其中，在包装过程中，围绕一批吸烟物品形成容器。在包装过程之后，最后用阻挡膜包裹并密封包装，该阻挡膜被设计为既用来保护防止诸如湿气的外部影响，还用来保留香气并保持吸烟物品的新鲜度。阻挡膜通常为柔性的片材，其优选地为透明的并且可以由玻璃纸、聚丙烯或其它类似的合成膜材料制成，阻挡膜通常被热收缩、加热并结合在包装周围。
阻挡膜可以被配置为沿一条线撕破或破坏，以使消费者能够在购买后取得包装内的吸烟物品。就这一点而言，该线可以为例如通过刻划形成在阻挡膜材料中的薄弱线(alineofweakness)，或者为沿着粘附在阻挡膜上的撕条的线。耳片或翼片通常定位在线的末端，以允许用户启动阻挡膜的撕扯或破坏。然而，已经发现阻挡膜的结合或密封可能与该薄弱线相干涉。具体地，耳片或翼片可能粘在阻挡膜上使得影响通常的对膜的撕破或破坏的方便性，使消费者更加难以移除阻挡膜并取得吸烟物品。
发明内容
据此，本发明的目的在于提供一种改进的用于包装物品，例如吸烟物品，的设备和方法，其解决了上述问题。本发明的另一目的还在于提供一种相应地改进的一包吸烟物品。
根据本发明，提供了一种具有权利要求1中列举的特征的用于包装物品，例如吸烟物品，的设备。在从属权利要求中还列举了本发明的各种有利的和/或优选的特征。
因此，根据一方面，本发明提供了一种包装设备，特别是用于包装吸烟物品，其包括：
包裹装置，用于在待包装的物品周围包裹阻挡膜，所述物品例如为一包吸烟物品；和
至少一个密封头，所述密封头具有接触表面，所述接触表面用于与包裹在物品周围的阻挡膜接触并且沿接缝密封所述阻挡膜，以在物品周围形成保护性壳体，
其中，所述密封头的接触表面是至少部分不连续的，以在密封头中提供非密封区。
如上所述，在本发明中，阻挡膜设有薄弱线或薄弱区(例如，易破或可破的线或条)，其有助于膜的移除并且使消费者获取物品。因此，使用本发明，可以在阻挡膜的结合或密封过程中设置密封头，使得非密封区至少部分并且优选地全部覆盖膜中的薄弱线或薄弱区。通过这种方式，密封头能够在不负面地影响膜中的易破或可破的线或条的情况下进行阻挡膜的所需的结合。
在优选的实施例中，包裹装置被配置在待包装的物品周围包裹阻挡膜，使得提供阻挡膜的重叠区，在该重叠区密封头沿接缝接触并密封阻挡膜。阻挡膜的该重叠区例如可以通过重叠所述膜的边缘部和/或折叠所述膜的边缘部而形成。
在优选的实施例中，所述密封头包括加热装置，用于加热接触表面以通过热结合或熔接的方式沿接缝实现阻挡膜的密封，即，当密封头接触包裹在物品周围的膜时。就这一点而言，非密封区与阻挡膜不接触，并且因而实际上执行很少的或不执行热结合或熔接，并且因此这样不会涉及定位在该区中的膜的易破或可破的线或区域。可替代地，可以利用粘结剂粘结通过由密封头在接触表面上施加压力而获得。在这种情况下，非密封区与阻挡膜不接触并且在阻挡膜上不施加压力，在该特定的非密封区中其也如期望地没有粘结剂。因而，可以在该区中避免粘结剂粘结。
在优选的实施例中，所述密封头是大致细长的形状，并且所述非密封区可以被提供为横向于所述密封头的纵向范围的中间区。就这一点而言，所述非密封区可以延伸达所述密封头的全部宽度的至少50％，优选地至少75％，更优选地至少90％。在一个特定的实施例中，密封头的接触表面沿纵向方向是完全不连续的，使得所述非密封区延伸跨越所述密封头的全部宽度。然而，在可替代的实施例中，接触表面可以沿纵向仅部分地不连续(并且因而也是部分连续的)，使得所述非密封区不延伸跨越所述密封头的全部宽度。具体地，在非密封区附近，接触表面可以横跨密封头的宽度的25％(优选地等于或小于10％)。通过确保接缝至少在小区域内是连续的，阻挡膜可以更好地保护防止诸如潮湿的外部影响，并且还更好地保留香气并保持吸烟物品的新鲜度。连续区域优选地位于接缝的外周或边缘部，但是可以同样位于其中心或中间部。
在特别优选的实施例中，非密封区的几何形状在二维或三维上变化。例如，非密封区的几何形状可以在密封头的接触表面所在的平面中变化。更特别地，非接触区的宽幅可以在密封头的宽度方向上(例如，线性地或以阶梯方式)变化。因而，在诸如耳片或翼片的致动装置被设置在阻挡膜上或中以被用户操作(例如抓取并拉动)从而致动或破坏膜中的薄弱线或薄弱区的情况下，密封头可以被设置为：当阻挡膜被沿接缝密封或热结合时，非密封区的较宽部覆盖耳片或翼片。所述非密封区由所述密封头中的凹部或空腔形成。这样，作为一种非密封区在接触表面所在的平面中的几何形状的变化的替代方案或附加方案，所述凹部或空腔的(垂直于所述接触表面的)高度或深度可以在密封头的宽度方向上变化。通过这种方式，在非密封区中由密封头赋予阻挡膜的辐射热的量也可以得到控制。
在优选的实施例中，所述包裹装置包括保持器，优选地为可旋转的圆盘的形式，用于保持一个或多个所述待包装的物品并且用于将包裹在阻挡膜中物品运输到密封头。所述密封头优选地相对于保持器能够移动，以接触包裹在相应物品周围的阻挡膜并沿接缝密封阻挡膜。在保持器为可旋转的圆盘的情况下，通过使圆盘绕其轴线旋转来运输包裹后的待包装的物品，并且密封头可以是相对于圆盘在径向方向上能够移动的，以沿接缝接触和密封阻挡膜。
在特别优选的实施例中，所述设备包括至少两个密封头，每个密封头被配置为在包裹在待包装的物品周围的阻挡膜中形成接缝的一部分。就这点而言，所述密封头优选地被配置为单独地并且相继地与物品接合。两个密封头例如可以围绕保持器或圆盘的外周彼此间隔设置，以单独地并且相继地接合每个物品。因而，所述密封头中的每一个密封头可以具有非密封区，并且各个非密封区具有不同的形状或构造，它们可以在形成接缝的过程中彼此配合和/或互相补充。
在优选的实施例中，待包装的物品包括一包吸烟物品，其包括被支撑在由刚性或半刚性材料(例如硬纸板、增强纸、纸板、纤维板、聚合物片材等等)形成的框架上或内的一批吸烟物品本身。当然，所述刚性或半刚性材料的框架也可以是相对柔软的，在不考虑其构成成分的情况下其应该在尺寸上是稳固的，以便给予吸烟物品的包装结构稳定性，并且由此在运输和储存过程中保护吸烟物品以防损坏(例如意外的压或挤)。因而，一批吸烟物品和框架使用阻挡膜通过将阻挡膜的重叠部密封起来以形成一个或多个接缝而被包裹或封闭。
根据另一方面，本发明提供了一种包装物品，例如一包吸烟物品的方法，该方法包括如下步骤：
提供用于包裹在待包装的物品周围的阳挡膜，所述阻挡膜包括易破线或部；
将阻挡膜包裹在待包装的物品周围；
提供具有接触表面的至少一个密封头，密封表面用于密封阻挡膜，其中，所述接触表面是至少部分不连续的，以在密封头中提供非密封区；和
使密封头接触包裹在物品周围的阻挡膜，以沿接缝密封阻挡膜，藉此所述非密封区被定位为至少部分地并且优选地基本上完全覆盖阻挡膜的易破线或部。
在优选的实施例中，所述方法包括加热密封头的接触表面以通过热结合或熔接的方式沿接缝实现阻挡膜的密封的步骤。此外，时密封头接触阻挡膜的步骤优选地包括通过密封头的接触表面在阻挡膜上施加压力。
在优选的实施例中，阻挡膜中的所述易破线或部包括：一条或多条薄弱线，例如刻划线或穿孔线，并且还可以包括致动装置，例如耳片或翼片，致动装置设置在阻挡膜上或中以被用户操作(例如，抓取并拉动)以致动或破坏易破线或部(例如弱线或弱区)。就这一点而言，所述非密封区理想地被定位为至少部分地并且更优选地完全地覆盖致动装置(例如，耳片或翼片)。
根据另一方面，本发明提供一种包装后的物品，例如一包吸烟物品，其由本发明的如上述实施例中的任一个所描述的装置和/或方法生产。
因而，本发明还提供了一种包装后的物品，例如一包吸烟物品，具有包括阻挡膜的外包裹层，所述阻挡膜沿接缝被密封以形成包围物品的保护性壳体。阻挡膜具有易破部或条和用于致动易破部或条的耳片，其中接缝延伸跨过所述易破部或条，并且接缝不覆盖耳片。
在优选的实施例中，在柔性阻挡膜中的易破部或条包括至少一个薄弱线，例如刻划线或穿孔线，并且接缝在它跨过膜的易破部或条的位置是至少部分不连续的。
因此，在另一个方面中，本发明提供一种包装后的物品，例如一包吸烟物品，其具有包括阻挡膜的外包裹层，所述阻挡膜沿接缝被密封以形成包围物品的保护性壳体。阻挡膜包括易破线或部，并且接缝延伸跨过易破线或部，接缝在它跨过膜的易破线或部的位置是至少部分不连续的。在接缝的不连续区域中，阻挡膜通常不被密封。
在优选的实施例中，接缝在接缝的全部宽度范围(即，横向于接缝的纵向范围)内的至少50％、更优选在至少75％、并且甚至更优选地在至少90％上是不连续的。在特别优选的实施例中，接缝在其宽度的至少一部分上被密封；优选地在其宽度的至少约10％上被密封。
附图说明
为了更全面理解本发明及其优点，在下面的说明中参照所附的附图更详细地解释本发明的示例性实施例，其中相似的附图标记表示相似的部件，并且其中：
图1示出根据一个特定实施例的用于包装吸烟物品的平片阻挡膜的平面图；
图2示出根据实施例的用于包装吸烟物品的装置的侧视图；以及
图3示出用于图2中的包装设备的密封元件的平面图和剖视图。
具体实施方式
附图被引入以提供对本发明的进一步理解，并且被引入并构成本说明书的一部分。附图图示了本发明的特定实施例，并且与本说明一起用于解释本发明的原理。随着参照下面的详细说明更好地理解本发明的其它实施例以及本发明的许多伴随的优点，将容易地领会它们。
可以领会的是，在商业上可行的实施例中可能是有用或必要的常见并熟悉的元素没有必然地被图示，以便于提供实施例的更概要的视图。附图中的元素没有必然地相对于彼此按比例图示。还可以领会的是，虽然可能以特定发生顺序描述或说明了方法实施例中的某些动作和/或步骤，然而本领域技术人员将理解关于顺序的这些特征实际上不是必需的。还可以理解的是，除了在本文中已经另外阐述了特定的含义，用在本说明书中的术语和表达具有通常的含义，正如关于它们对应的各自的探究和研究领域给予所述术语和表达的含义。
参照附图1和2，在图2的侧视图中部分示出了根据本发明的优选实施例的包装设备1。装置1包括包裹装置2，其被配置用于将阻挡膜4的片3包裹在待包装的物品P周围。在该特定实施例中的阻挡膜的片3在图1中被明确图示为大致矩形的片，其具体地被设计为通过包裹装置2包裹在香烟、小雪茄烟或其它这种吸烟物品的大致矩形的包P的周围。就这一点而言，图1标识了阻挡膜片3的对应于吸烟物品的包P的“前”和“后”面的那些部分。此外，带有剖面线或阴影线的阻挡膜片3的周边外区域5表示在已经用膜包裹包P之后、所述片3的重叠的部分。
如图1所示，阻挡膜4的片3包括两行穿孔和/或刻划线6，它们平行于彼此延伸横跨片3的宽度，以在阻挡膜中形成易破的或可撕破的条7。就这一点而言，在该易破条7的一个端部区域处设置耳片或翼片8，作为用户抓取并拉动以致动易破条7并由此沿着穿孔和/或刻划线6破坏阻挡膜4的致动装置。
可以在阻挡膜材料的连续卷中提供附图的图1中图示的阻挡膜4的单个片3，沿从成卷的卷供给到包装设备1的包裹装置2的膜的行进方向(由箭头“D”表示)，所述阻挡膜材料的连续卷包括沿片各自的前缘L和后缘T彼此串联连接的多个片3。对于应用于吸烟物品的典型的包P，阻挡膜4的片3的典型尺寸在图1中具体地以毫米为单位表示。然而，本领域技术人员可以领会这种尺寸仅仅代表本发明的一个特定实施例，并且这些尺寸在其它实施例中可以不同，而不影响本发明构思。在该实例中的阻挡膜4优选地由透明的聚丙烯材料构成，其中薄弱线6优先地通过激光穿孔和/或刻划预形成在膜4中。替代地，阻挡膜4可以包括撕条，并且可以沿着撕条的纵向边形成薄弱线6。
再次参照附图中的图2，包裹装置2包括保持器10，该保持器以旋转圆盘的形式提供，以用于保持并运输多个包P，其中每个包均已被阻挡膜4的片3包裹。就这一点而言，旋转圆盘10被安装成绕中心轴线A旋转，并且包括沿圆盘10的外周间隔开的多个凹陷或凹部11以用于分别接纳并保持被相应的阻挡膜4的片3包裹的吸烟物品的单独的包P。从图2的立体图中，各个包P的“底”端以及它们的阻挡膜4的片3的折叠和重叠部5面朝纸外。
进一步参考图2，可以看出包装设备1包括两个密封站20、20’，每个密封站具有用于将阻挡膜4的片3密封在各自的包P周围的密封头21、21’(例如，通过热结合或熔接)。具体地，如图2的细节放大图所示，密封头21包括细长的密封元件22(以剖面图示出)，密封元件具有用于沿被保持在圆盘10的凹陷或凹部11中的包P的径向面朝外的侧边与阻挡膜4的重叠部5接触的接触表面23。密封头21通常包括加热装置(例如电加热元件，未示出)，用于加热所述密封元件22，使得接触表面23在包P的侧边的整个长度上沿着接缝9密封或熔接阻挡膜4，并且阻挡膜4提供围绕所述包的保护性外壳。就这一点而言，圆盘10通过绕轴线A的沿方向R的旋转将被保持在各个凹陷或凹部11中的包P运输到两个密封站20、20’中的每一个密封站。在密封站20、20’中的每一个密封站中，包P的侧边与形成在围绕圆盘10的弯曲的静止的盖板14中的对应的槽12、13对齐。然后圆盘10与包P停止在这些位置，以使密封头21、21’能够径向向内移动穿过槽12、13，以通过接触表面23、23’接合并密封阻挡膜4。
现在参考图3，更详细地图示了密封头21、21’的密封元件22、22’。图3的上部以平面图或仰视图(即，沿相对于圆盘10的轴线A的径向方向)示出了每个对应的密封元件22、22’的接触表面23、23’。接触表面23、23’中的每一个接触表面具有非密封区24、24’，非密封区沿相应密封元件22、22’的横向于其纵向范围的宽度范围内延伸。就这一点而言，非密封区24、24’用剖面线表示，并且由密封元件22、22’中的每一个密封元件的表面中的凹部或空腔25、25’形成。因此，非密封区24、24’中的每一个非密封区在对应的密封头21、21’的接触表面23、23’中形成至少局部不连续部。为了清楚起见，在下面的说明中，两个密封站20、20’将分别被称作第一密封站20和第二密封站20’。第一和第二密封站20、20’的各种部件也将用术语“第一”和“第二”表示，这有助于使本说明书的更加清楚。
例如，在第一密封头21中，非密封区24具有基本一致或者恒定的宽幅(breadth)26，并且延伸达第一密封元件22的宽度27的90％。通过这样，第一密封头21的接触表面23在第一密封元件22的右侧保持连续的窄带或条(即，约为接触表面23的整个宽度27的10％)，如图3所示。
相比之下，第二密封头21’的非密封区24’横向延伸达第二密封元件22’的全部宽度27’，致使接触表面23’在该区域完全不连续。此外，非密封区24’的宽幅26’还在接触表面23’的平面中以阶梯形式在右侧的较窄宽幅和左侧的较宽宽幅之间变化，如图3所示。
进一步参考图3，图的下部以在垂直于圆盘10的轴线A的平面中沿方向X-X和X’-X’截取的剖面图示出了第一和第二密封头21、21’的密封元件22、22’。以这种方式，可以看出相应的第一和第二密封头21、21’的非密封区24、24’的几何形状在三维上发生变化。因而，当第一密封头21的接触表面23与沿着吸烟物品的包P的侧边区域重叠的阻挡膜4接触时，在第一密封元件22的右侧标注“a”的区域与阻挡膜4直接接触，而标注“b”的部分与阻挡膜4间隔开(例如0.1mm)并且不接触阻挡膜4。实际上，整个非密封区24不接触阻挡膜，并且因此对接缝9的形成不起作用。形成非密封区24的凹部或空腔25的高度28越高，在非密封区24内第一密封元件22与阻挡膜4之间的距离越大，并且来自密封元件22的辐射热可能越少地影响在该非密封区中的阻挡膜。关于第二密封头21’，明显的是，在非密封区24中第二密封元件22’与阻挡膜4更进一步地间隔开(即，由于空腔25’的高度28’)。在右侧由“c”表示，间距可以为约0.1mm，而它在第二密封元件22’的宽度27’上近似线性地增大到由“d”表示的一侧的约0.2mm。这里应当注意，虽然在图3中高度28、28’被呈现为分别在密封元件22、22’的宽度27、27’范围内变化，但是它们也可以沿密封元件22、22’的所述宽度27、27’具有基本恒定的数值，而不会明显改变密封元件的密封性能。
通过设置第一和第二密封元件22、22’，使得其非密封区24、24’与在相应密封站20、20’的每个密封站处的阻挡膜4的片3中的易破条7对齐，从而可以沿在包P的侧边处的接缝9、9’密封或热结合阻挡膜4，而不会负面地或不利地影响用户对易破条7的后续操作。即，通过以这种方式配置密封元件22、22’，第一和第二密封头21、21’确保沿接缝9、9’形成令人满意的密封，同时非密封区24、24’同时确保阻挡膜4的片3中的易破条7保持其操作功效。就这一点而言，第二密封头20’被优选地设置为使得非密封区24’的较宽的部分覆盖在易破条7的耳片或翼片8上，由此确保阻挡膜4的热密封或结合最少地影响致动装置，并且由此还确保合适地开始易破条7的致动。
虽然本文图示并描述了本发明的具体实施例，但是本领域技术人员可以领会存在多种替代和/或等价的执行例。就这一点而言，应当注意，待包装的物品P的形状对本发明来说不是关键的。香烟包装通常具有矩形形状，但是其它形状也是可行的。
应当领会的是，示例性的实施例或多个示例性的实施例仅仅是举例，而不意图以任何方式限制范围、适用性或构造。而是，前述摘要和详细说明将为本领域技术人员提供实施至少一个示例性实施例的方便的路径，应当理解，在不偏离在所附的权利要求书和它们的合法等价方式中阐述的范围的情况下可以对示例性实施例中所描述的元素的功能和设置作出各种改变。例如，虽然关于图3描述的具体实施例包括沿着包P的侧面形成两个平行的接缝9、9’的两个密封元件22、22’，但是可以领会的是，本发明的装置1和方法还可以包括具有一个密封元件22以沿着每个物品或包装P的侧面形成单一的接缝9的单一的密封头21。通常，本发明意图覆盖本文讨论的具体实施例的任何修改或变形。
此外，可以领会的是，在本文档中，术语“包括”、“包含”、“含有”、“具有”以及其任何变形被理解为具有包含性的(即，非排他性的)意义，使得本文所描述的过程、方法、设备、装置或系统不限于所列举的那些特征或部件或元素或步骤，而是可以包括未明确列出或者对所述过程、方法、用品或装置来说固有的其它元素、特征、部件或步骤。此外，除非明确另有说明，术语“一”(a)或“一个”被理解为是指一个或多个。而且，术语“第一”、“第二”、“第三”等等仅用作标记，并且并非意在给它们的对象强加数量要求或建立某一重要等级。
