发明内容
本公开涉及一种包装，所述包装具有：基底构件，所述基底构件限定了一腔体，所述的腔体被配置成接收其中的物品；以及凸缘，所述凸缘限定基底构件的外边缘并围绕所述腔体。一封盖构件，其构造成附接到基底构件的凸缘并覆盖腔体以将物品保持在其中。进一步地，所述封盖构件被构造为从所述基底构件的凸缘剥离以提供通向所述腔的通路，并且被构造为重新密封至所述凸缘。封盖构件包括构造成与基底构件的凸缘接合的第一层和经由粘合剂层层压到第一层的第二层。粘合剂层包括图案化施加的压敏粘合剂，该压敏粘合剂形成与基底构件的凸缘对准的周边。粘合剂层的中央部分由永久粘合剂形成并且配置为将第一层保持固定到第二层。第一层中的刻痕线围绕粘合剂层的永久粘合剂部分的至少一部分。第二层被构造成当至少一部分封盖构件从基底构件上剥离时与第一层分离，并且压敏粘合剂部分允许第一层的周边从刻痕线向外与第二层分离。底切刻痕线设置在与凸耳相邻的位置，在与封盖的热密封直接相邻的位置与基底构件的凸缘相邻。
本公开还涉及柔性的多层封盖材料，其构造成附接到基底构件的凸缘以将物品密封在基底构件的保持腔内。封盖构件被构造成被热密封至基底构件，然后从凸缘至少部分地剥离，然后再密封至凸缘。封盖材料包括底层或第一层以及第二层或顶层，两者通过粘合剂层彼此层压。粘合剂层包括形成周边的图案化施加的压敏粘合剂，其中图案与预期的基底构件的凸缘对准。粘合剂层的中央部分由永久粘合剂形成并且被配置为保持第一层的中央部分固定到第二层。刻痕线设置在第一层中，并围绕粘合剂层的永久粘合剂部分的至少一部分。第二层被配置为当至少部分封盖构件被剥离时与第一层的周边部分分离。压敏粘合剂部分允许第一层的周边从刻痕线向外与第二层分离。在与热密封区域直接相邻的位置处设置一个或多个底切边缘刻痕线。在边缘刻痕线的外侧设置有突出的凸耳构件。可以将形成的封盖材料切割并根据需要应用到容器上。
通过下面结合附图的详细描述，本发明的其它特征和特征的组合将变得显而易见。

详细说明
在附图中，在相同的数字标识相同的元件的情况下，示出了由数字10标识的包装或容器的实施例。如图1所示，包装10包括相对刚性的基底构件12，该基底构件12限定了一腔体，所述的腔体被配置成接收其中的物品。凸缘14限定了基底构件的外边沿或边缘并且围绕腔体。由柔性腹板材料形成的封盖构件16附接到基底构件12的凸缘14并覆盖腔体以将物品保持在其中。如图2所示，封盖构件16被配置为从基底构件12的凸缘14剥离以提供通向空腔的通道。封盖构件16包括第一或底层18、第二或顶层20以及用于将顶层20固定至底层18的粘合层22。底层18接合并固定到基底构件12的凸缘14上。底层18优选地热密封至凸缘14的顶表面以形成永久性结合。
参考图3和图4，粘合剂层22包括图案化施加的压敏粘合剂24，该压敏粘合剂形成了与基底构件12的凸缘14对准的周边。粘合剂层22的中央部分由永久粘合剂26形成，并且被配置为将第一层18保持固定到第二层20。第一层18中的刻痕线28围绕粘合剂层22的永久粘合剂26的至少一部分。油墨层30设置在第二层20的底表面或下侧。第一层18的底表面或底侧的一部分被热密封32到凸缘14的顶表面。
如图2所示，第二层20被构造成与第一层18的周边部分34分离，并且可以从基底构件12的凸缘14上剥离。第一层18的周边部分34是被热密封32到凸缘14的部分。当第二层被剥离时，压敏粘合剂24与第一层分离。在刻痕线28的位置处，第一层18的中央部分36与周边部分34分离。中心部分36通过永久粘合剂26保持固定到第二层20，并且与第二层20一起剥离。暴露的压敏粘合剂26允许将第二层20重新密封到第一层18的周边部分34，以将内容物重新固定在基底构件12的腔内。
封盖材料16的凸耳部分38被示出为延伸出基底构件12的凸缘14的外边缘。底边沿刻痕线40设置在第一层18中。刻痕线40被示出为邻近热密封32。在打开期间，使用者抓住凸耳38以开始剥离和分离封盖材料16。在凸耳38的区域中，第一层18的一部分保持固定到第二或顶层20。在边缘刻痕线40处，第一层的周边部分34开始与第二层分离。可以通过压敏粘合剂24将第二层完全从包装10中去除，或者将其一部分保持固定到第一层18的周边部分34。
在图5-8中，示出了包装110的另一实施方式。基底构件112具有多个侧壁，这些侧壁以通常矩形的形式构造。周边凸缘114从侧壁向外突出并形成连续的边缘表面。封盖材料116附接到凸缘114以密封由基底构件112形成的腔体。在图6中，示出了封盖材料116部分地向后剥离以暴露空腔。在封盖材料116的一个拐角142处形成凸耳138，其邻近由基底构件112的侧壁形成的拐角。
在图7中，封盖材料的顶面显示具有暴露的结构元件。封盖材料116被热密封132到凸缘114。内部刻痕线128设置在热密封132的内部。刻痕线138从凸耳拐角142基本上围绕凸缘114的内周延伸，但是在相对的拐角144处不连接。刻痕线138在剥离时形成第一层118的中央部分136与周边部分134的分离，如图6所示。如在图1-4的实施例中，周边部分134被热密封132到凸缘114并且通过图案化施加的压敏粘合剂124固定到顶层或第二层120。在封盖材料116的中心，邻近第一层118的中央部分136的118、120两层之间提供永久粘合剂。
在剥离角142处，封盖材料116的边缘突出穿过热密封132以形成凸耳138。在第一层116的下侧形成两条平行的刻痕线140。刻痕线140是弯曲的，并且在基底构件112的拐角142处与凸缘114相邻的热密封区域132部分重叠。可以考虑将热密封施加到封盖材料上，并在填充基底构件的腔体之后执行。
单个底切，例如图3和4中的边缘刻痕线140，足以允许剥去封盖材料16、116的各层的开口。一次剪切可能更容易完成。但是，可以提供多个底切，例如图7和8中所示的平行刻痕线140，并且可以适应与热密封32、132的配准错误。优选地，边沿刻痕线应在封盖的周边的热密封到基底构件的凸缘的0.125英寸和0.375英寸之内。如图所示，刻痕线可以与热密封区域重叠。如果与热密封的距离较大，则凸耳可能无法正确剥离这些层。所有刻痕线可以通过激光、机械或其它方式执行。激光微穿孔工艺是优选的。如果在封盖的中央部分与图案永久粘合剂对准，则可以更容易地完成这种形式的刻痕。刻痕优选在各层附接之后进行，并且优选地延伸穿过第一层。
在所示的两个实施例中，可以在将产品填充到基底构件的腔体中并且将封盖材料热密封附接到凸缘之后，完成封盖材料的最终修整。该最终修整切穿封盖层的外围边缘，并且不需要对包装进行最终的顶部模切。
在封盖材料的中央区域中永久性粘合剂的提供改善了中央区域的清晰度。因此，可以使用透明容器以对容器内的产品进行目视检查。油墨层不需要连续穿过封盖的中央区域。通常，油墨或图形将与所选的粘合剂材料化学相容。防雾涂料也可以与底漆材料一起施加到这些层上。
在一个预期的实施方案中，封盖材料可包括92号PET的第一或底层和100号PET的第二或顶层。除了在油墨层中施加图形之外，可以想到封盖材料是柔性的并且优选是透明的。与封盖材料相比，容器相对较硬，并且可以由APET材料形成。可以在第一层的底侧上提供密封剂层或涂层，以促进该层与凸缘的热密封。
一个或多个相关的示例性实施例描述和说明了本发明。从前述内容中，本领域技术人员应当理解，在不脱离本发明的精神和范围的情况下，可以在其中做出各种其它改变、省略和添加，并且本发明的范围由前述权利要求描述。
