Abstract

在此描述了一种尤其适用于经过预焙烤和/或冷冻的面制品,比如比萨饼,calzones及馅饼,的包装件(2),在该包装件(2)中与所述面制品相正对的侧面上带有一所谓的敏感涂层,比如由经过聚酯涂敷过的压花镀金属或者金属制涂层所形成的一敏感涂层,其中该包装件(2)的底部(4)被设计成环绕一中部区域(10)带有多个通气开口(8)。

Description

尤其适用于经过预焙烤和冷冻的面制品的包装件
本发明涉及一种如权利要求1中前序部分所述类型的包装件，该包装件尤其适用于经过预焙烤和冷冻的面制品。
所公知的此类包装件有多种形状，并且可以用于许多特殊目的。为了用于那些希望在公知的微波炉中进行烹调的、经过过焙烤和冷冻的面制品，比如比萨饼，calzones及馅饼，例如可以使用托盘状或者圆盘状包装件，并且最好在该托盘状或者圆盘状包装件的内部带有一专用的微波反射金属涂层。用于微波炉中的这些经过专门涂敷过的包装件在本技术领域中被称为“微波敏感件”。为了避免所述面制品过热和被烤焦，存在有另外一种公知的“安全型微波接受器”，在该“安全型微波接受器”中微波反射涂层至少在穿孔形成的图案或者在局部区域上不带有所述的反射涂层。在该装置中需要注意的是，如果面制品与所述反射涂层发生接触，那么该反射涂层仅具有所需的效果。
然而，尤其是在比如比萨饼的中部，将会产生焙烤或加热不均匀的问题，也就是说将会发生在某些地方过热并被烤焦而某些区域仍然湿润且未被焙烤的现象。从而，这些位于中部的湿润、未焙烤区域或者位于外周部分(边缘)处的过热区域在实际中仅能够通过制备相对较小的比萨饼来加以避免。
本发明的目的在于明示出一种经过改进的包装件，该包装件属于导言中所述的类型，并且通过利用该包装件所述缺陷可以借助于简单方法来加以克服。
根据本发明的包装件其特征在于：该包装件的底部被设计成带有多个环绕一中部区域的通气开口。从而借助于简单方法，在此可以获得一种新颖并得以改进了的包装件，其中所述与已知包装件相对应、存在有过热或者未焙烤区域的缺点得以克服。在该装置中需要注意的是，根据本发明的包装件的外周形状可以是圆形，卵形，椭圆形，正方形，矩形或者根据所想及所需而设计出的其他形状。
通常，根据本发明用于经过过焙烤或者冷冻面制品，象比萨饼，calzones及馅饼，的包装件的高度可以被忽略或者相当小，但是比如用于那些较大冷冻面制品，象需要在一微波炉中进行焙烤的白面包，该包装件的高度将会较大，这也就是至少这样一种较高包装件中带有穿孔(通气开口)的侧壁下部也可以以这种方式来进行设计的原因。
根据本发明的包装件，比如，可以被进一步设计，以便使得所述通气开口大致呈三角形并且具有向外逐步增大的横向尺寸。
或者根据本发明的包装件可以被设计成能够使得所述通气开口由相对较小的圆形通孔组成，这些圆形通孔被排布在若干个同心的环形区域中，并且在各个环形区域中的通孔数目逐渐增大。
为了确保在所述底部处与通气开口之间具有良好的连通性，根据本发明的包装件从而可以被设计成其底部表面在穿孔成形的支撑区域中具有较大的厚度或深度，以便所述包装件底部中包括有所述中部区域的较大部分可以由一支撑表面自由地承载。
为了以一种简单的方式来对所述敏感涂层的效果以及所述通气开口的效果进行调整，并且对所述面制品进行包覆，这将更为有益，即根据本发明的包装件被设计成使得所述位于包装件底部侧面上的通气开口借助于一个或者多个可剥离的标签来进行贴覆，其中在这些标签中朝上与所述圆盘或者托盘下侧面相正对的侧面上比如带有一敏感涂层，所述标签的主要功能是向下包覆所述面制品，以便该包装件仅需要带有比如一透明的外盖即可作为适合的销售包装。
相应地，根据本发明的包装件被进一步设计成能够使得该包装件沿其圆周或者外周边缘具有一环形狭窄区域，该区域具有较大的厚度或者深度，以便该包装件底部中包括有所述中部区域的较大部分被置于略微高于所述环形区域的位置处。该区域还可以更为有益地被设计成带有径向通气凹槽，以便在该包装件的底部处能够确保与所述通气开口之间的有效连通。
一种根据本发明并且被设计成一用于比萨饼或者类似面制品的圆形包装件的包装件，该包装件被设置成借助于若干个径向穿孔而被分隔成多个包装件，并且在一圆形中部区域中带有向下弯曲的边缘部分，这些边缘部分被设置成形成“支脚”，来对所述经过分隔开的包装件的顶端进行支撑。
一种根据本发明并且被设计成一用于比萨饼或者类似面制品的圆形包装件的包装件，该包装件由这样一包装件制成，即该包装件在平整状态下具有一波纹状外周边缘，而在向上弯曲的状态下沿其圆周具有向下的支脚，该支脚由所述外周边缘中的波峰形成，并且具有由所述外周边缘中的波谷所形成的径向通气开口。
一种根据本发明并且被设计成一用于比萨饼或者类似面制品的圆形包装件的包装件，该包装件被设计成带有一外周环形支撑表面，并且其支撑或者底部表面又被设计和定位成能够使得在该支撑或者底部表面与被设计成带有径向通气开口的所述支撑表面之间具有约为3-20毫米的距离。
在下文中将参照附图对本发明进行更为详细的描述，其中：
附图1示出了穿经一根据本发明的包装件实施例的剖视图，
附图2示出了一根据本发明的包装件实施例的平面正视图，
附图3示出了一根据本发明的包装件第二实施例的平面正视图，
附图4示出了一根据本发明的包装件第三实施例的平面正视图，
附图5示出了一根据本发明的包装件的平面正视图，其中在该包装件上图示出了不同类型的通气开口，
附图6示出了一根据本发明的包装件第四实施例的平面正视图，
附图7示出了穿经根据本发明在附图5中所示出的包装件的剖视图，
附图8示出了穿经根据本发明在附图6中所示出的包装件的剖视图，
附图9示出了一根据本发明的包装件第五实施例的平面正视图，
附图10示出了穿经根据本发明在附图9中所示出的包装件的剖视图，
附图11示出了一平面正视图，用来图示在一根据本发明的包装件底部上成形通气开口的不同方式。
在附图1中所示由卡纸板，塑料或者一种适合的包装材料(包括淀粉材料)所制成的包装件2，带有一个呈所谓的敏感涂层形状的表面涂层，该表面涂层比如可以由一经过聚酯涂敷过压花金属涂层制成，由于该包装件2将被用于在一微波炉中进行焙烤的比萨饼或者馅饼，所以该包装件2包括有一底部部分4和闭合的倾斜侧壁6。该包装件2中的底部部分4，正如在附图2中所示出的那样，在中部区域10的外侧被设计成带有大体呈三角形的通气开口8。可选择地，正如在附图3中所示出的那样，底部4可以被设计成带有大量的较小通气开口12，这些通气开口12在所述中部区域10的外侧被排布在若干个同心的环形区域中。或者正如在附图4中所示出的那样，所述底部也可以被设计成带有相对较少的较大三角形通气开口14。
正如在附图1中所能够看到的那样，包装件2具有一外围环形边缘16，该边缘16具有较大的深度，以便所述底部4可以被架空来与一支撑面分离。所述环形边缘16最好以一种未示出的方式而设计成带有径向通气凹槽18，以便与所述通气开口8，12或者14形成连通。
最后，应该指出的是，在本发明的范围之内也可以在所述包装件2底部部分4的中部区域10中带有多个通气开口。同样，底部表面中的所述支撑区域也可以通过将通气开口的边缘向下弯曲而形成(附图11)。
正如在附图5中所示出的那样，根据本发明的包装件20的底部部分4带有若干个不同类型的通气开口，换句话说即其宽度径向向外增大的三角形通气开口8，由圆形或者椭圆形通气开口22所形成的开口组或者沿该包装件的边缘区域排布的多个狭窄同心通气开口24，与此同时保持所述中部区域10远离这些通气开口。并且正如在附图7中所能够进一步明白的那样，所述包装件2被设计成分别在外侧环形支撑区域中带有径向通气开口26和支脚28。
再有，在附图6中所示出的平板状包装件具有一底部表面32，该底部表面32被设计带有多个环绕一中部区域10的径向通气开口34。该包装件30的外周边缘轮廓36呈波纹状，以便最终的包装件30，正如在附图8中所示出的那样，在由“波峰”所形成的支脚之间得到径向通气开口38。可选择地，包装件30可以根据同一原理进行设计，但是带有一圆形的边缘轮廓。在这种情况下，包装件30可以被设计成在其环形支撑裙部中带有径向通气开口42。
在附图9和10中所示出的包装件4被用于可切割开的比萨饼，即在仅有一部分比萨饼需要在一微波炉中进行焙烤的情况下使用。该包装件44具有三个径向穿孔46，这些穿孔46从外周边缘切口48向内延伸至一专门设计的中部区域50处。在该包装件44的圆形边缘52中带有向下弯曲的倾斜“支脚”51，当包装件44中包括有已经被切割开的比萨饼时，这些倾斜“支脚”51用于支撑该被分隔开的包装件44的顶端(附图10)，以便在该被分隔开的包装件44的下方仍然能够得到较好的通气性。已经可以看出，在没有进行预先成形操作的条件下，很难成形所述径向穿孔46。在该装置中还已经可以看出，最好首先对径向弯曲线53进行模压，以便所述材料被拉伸或者被预拉伸，从而可以解决预先成形穿孔46的问题。
另外，在附图10中示出了所述包装件44的外侧支撑边缘也分别带有径向通气开口54和支脚56。该包装件44被设计成与参照附图6的包装件30一样，均在底部表面上带有若干个通气开口，但是这些通气开口均由点划线示出，该包装件44也可以带有圆形通气开口，或者也可以带有由所述类型的通气开口所组成的组合式通气开口。
附图11示出了如何以不同的方式在包装件的底部部分中设计通气开口，比如设计普通的通气开口8，34。在58处可以看到一个通气开口，该通气开口通过设计一由实线60所示出的切口而形成，此后围绕弯曲线62向下旋动而形成折板61，以便该折板61中向下正对的自由边缘可以用作用于该包装件底部表面的支撑件。在63处利用相同的原理成形有一T形切槽，此后将所形成的两个折板向下弯曲并且用作局部承载支脚，来对所述底部表面进行支撑。
借助于64，65和66，在此图示出了一个相应的原理，即在这些部位处仅通过成形锯齿状，波纹状或者矩形曲线切槽(rectangularcurve cutting)来形成两个折板，这些折板随后可以围绕间断的弯曲线来向下旋动。通过利用这种不规则的裁切线，可以达到更进一步的效果，即沿该包装件下侧面的通气装置更离散地存在，与此相反在向下旋动的折板之间则形成了相对紧密的径向通气管道。利用该装置中，可以带来更进一步的效果，即所述包装件材料中的吸收性边缘部分被暴露出来，以便由材料本身来从比如比萨饼中去除掉过多的水分。如果，比如由纸浆制成的包装件带有微波接受器(susceptor)和表面涂层，那么这种由暴露出来的材料边缘所产生的吸收作用自然会得以增强。
最好，根据本发明的包装件由这种材料制成，即在其一个侧面的整个部分上带有敏感涂层，但是对于某些面制品，比如馅饼，的应用领域来说，最好该包装件的垂直环形边缘部分不带有敏感涂层。
另外，需要强调的是，根据本发明的包装件能够对生的面制品，比如通过灌充而制成的比萨饼，进行完全包裹，在该制品被包裹在所述包装件中之后，该制品立即被进行冷冻以作为冷冻食品进行储存。在食用时，带有比萨饼的包装件被直接放入一微波炉中进行焙烤以便食用。换句话说，可以在无需配置一个专用烤炉的条件下通过灌充来制备比萨饼，这也着实明显暗示着对制备工艺的明显简化。
最后，需要指出的是本发明的原理——在一包装件中经过敏感涂层涂敷过的支撑表面中设计通气开口——可以与用于比萨饼或者其他面制品的公知箱状包装件结合使用，其中在所述箱状包装件的外侧面上带有一敏感涂层。本发明是将比萨饼从所述箱子中取出并且将其放置在该箱子中的敏感涂层上，以便在比萨饼的下方形成良好的通气性。当所述箱子中的敏感涂层被用作一高架式焙烤底层来在一微波炉中对比萨饼或者其他面制品进行支撑时，为了进一步优化所述的通气性，本发明中的敏感涂层还可以带有若干个通气开口，或者被设计成带有需要进行模压的备用穿孔部分。
另外一种可能是，用于比萨饼或者其他面制品的箱状包装件的底部表面内侧被设计成带有这样一个部分，即一个带有敏感涂层并且备用于进行模压的部分，如同对所述敏感涂层部分进行模压一样，以便在该箱子的底部形成开口。随后对其进行翻转，使得带有开口的箱子底部朝上，此后在翻转状态下将所模压出的敏感涂层部分置于所述开口的上方，以便使得所述敏感涂层部分不会落入具有相同形状的开口中，其中所述敏感涂层比如可以呈三角形。该敏感涂层部分也可以进一步被设计成带有多个通气开口，这些通气开口比如可以通过对备用的穿孔开口进行模压而形成。

Claims (10)

1.一种尤其适用于经过过焙烤(预焙烤)和/或冷冻的面制品，比如比萨饼，calzones，及馅饼的包装件，其中在该包装件中与面制品正对的侧面上带有一所谓的敏感涂层，比如由经过聚酯涂敷过的压花金属涂层所形成的敏感涂层，其特征在于：所述包装件的底部被设计成环绕一中部区域带有多个通气开口。
2.根据权利要求1中所述的包装件，其特征在于：所述通气开口大致呈三角形，并且其横向尺寸向外逐步增大。
3.根据权利要求1中所述的包装件，其特征在于：所述通气开口由相对较小的圆形通孔组成，这些通孔排布在若干个同心的环形区域内，并且在各个区域内的通孔数目逐步增大。
4.根据权利要求1中所述的包装件，其特征在于：在所述包装件的外侧面上，所述通气开口借助于一个或者多个可剥离的标签进行贴覆，在这些标签中朝上与所述圆盘或者托盘的下侧面相正对的侧面上比如带有一敏感涂层。
5.根据权利要求1中所述的包装件，其特征在于：其底部表面在穿孔成形区域具有一定的厚度或者深度，以便该包装件底部中包括有所述中部区域的较大部分可以被架空来与支撑表面分离。
6.根据权利要求1中所述的包装件，其特征在于：沿所述包装件的圆周或者外周边缘具有一环形狭窄区域，该区域具有较大的厚度或者深度，以便使得所述包装件底部中包括有所述中部区域的较大部分被置于一略微高于所述环形区域的位置处。
7.根据权利要求1和6中所述的包装件，其特征在于：所述环形外周区域被设计成带有径向通气凹槽。
8.根据权利要求1中所述并且被设计成一个用于比萨饼或者类似面制品的圆形包装件的包装件，其特征在于：其借助于径向穿孔而被分隔成多个包装件，并且在一圆形的中部区域中带有向下弯曲的边缘部分，这些部分被设置成形成“支脚”，来对被分隔开的包装件的顶端进行支撑。
9.根据权利要求1中所述并且被设计成一个用于比萨饼或者类似面制品的圆形包装件的包装件，其特征在于：其由这样一个包装件制成，即该包装件在平整状态下具有波纹状外周边缘，而在向上弯曲的状态下沿其圆周具有向下的支脚，这些支脚由所述外周边缘中的波峰形成，并且具有由所述外周边缘中的波谷所形成的径向通气开口。
10.根据权利要求1中所述并且被设计成一个用于比萨饼或者类似面制品的圆形包装件的包装件，其特征在于：其被设计成带有一外周环形支撑表面，并且其支撑或者底部表面被设计和定位成能够使得在该支撑或底部表面与所述被设计成带有径向通气开口的支撑表面之间具有约为3-20毫米的间隔。
