  • the densely laid unit forms a hollow structure surrounded by multiple walls, which is arranged so that it can greatly save materials under the premise of ensuring the supporting function, and also has a relatively good buffering function when it is squeezed or impacted.
  • the hollow structure also makes it possible to fold the densely laid unit under certain circumstances, which is convenient for storage and transportation. In other words, the hollow structure can make it convenient to switch the foldable inner packaging structure between the unfolded structure shown in Figure 12 and the folded structure not shown.

That is to say, in the aforementioned other exemplary embodiments, some of the hollow closely spaced units constituting the packaging structure are provided with weak portions, and other hollow closely spaced units constituting the packaging structure are not provided with weak portions.
  • weak portion refers to a portion whose strength (such as tensile strength or compressive strength) is weakened relative to the rest of the portion.
  • tension or pressure When a material is subjected to tension or pressure, it will first break or tear at the weak portion due to the stress concentration at the weak portion.
  • the densely packed unit directly below the article will be subjected to downward pressure, and the wall below the edge of the article will generate tension relative to the portion that is not pressed downward, and due to the existence of the weak portion, this tension will cause the wall to be torn apart.

  • the weak portion may also include a cutout, a tear line, or the weak portion may be made of a material having a different tear strength than the rest of the wall.

  • One of the characteristics of the structure formed by the densely packed unit is that it will be crushed when subjected to axial load. As shown in Figure 14, when the top of the densely packed unit is subjected to pressure, the densely packed unit will have a tendency to fold or crush downward. The force represented by the arrow F in Figure 14 is the downward pressure acting on the edge of the densely packed unit (where the three walls meet).
  • the foldable inner packaging structural member composed of honeycomb densely laid units has the same structure per layer and is approximately isotropic, the structural stability is good, generally speaking, a large force is required to be crushed, and the weight of commonly used items is not easy to deform the densely laid structure when placed on the honeycomb densely laid units, therefore, the above structure has better compression resistance and bending resistance.
  • this pulling force F1 makes it more difficult for the closely spaced units to be crushed, and therefore, the foldable inner packaging structure composed of honeycomb closely spaced units can be used to support articles of various shapes, regardless of whether their area is larger or smaller than the floor area of the foldable inner packaging structure.
  • the wall of the densely packed unit is made of a tearable material.
  • the tearable material for example, paper or aramid paper can be used.
  • the tearable material may tear when subjected to shear force. Therefore, when pressure is applied to one or more densely packed units as described above, there is a possibility that the wall 230 between the unpressurized edge 251 and the pressurized edge 251 is torn by the shear force.
  • the wall of the densely packed unit usually has a certain supporting function, the densely packed unit is usually crushed before tearing.
  • the wall of the densely packed unit can adopt a single-layer structure and/or a double-layer structure.
  • the wall of the single-layer structure is formed by a layer of paper
  • the wall of the double-layer structure is formed by two layers of paper bonded to each other.

  • the tension F1 gradually generates a tendency from the horizontal to the oblique downward, and therefore there will be a vertical component force in the crushing process, and this vertical component force will cause the surrounding close-laid units that are not under pressure to be gradually crushed, thereby causing the crushing behavior to gradually spread in the horizontal direction.
  • this crushing and spreading behavior in the horizontal direction occurs before the wall is torn, that is, the crushing and spreading behavior has occurred before the pressure that causes the wall to tear has not yet reached the size of the pressure.
  • the close-laid unit under pressure and the close-laid unit under no pressure refer to whether the direct pressure generated by, for example, articles directly above the close-laid unit) cannot form an obvious tearing zone (a completely vertical tearing crack is formed in the best case), so that the article cannot be smoothly pressed into the foldable inner packaging structure or even if the article is pressed into the foldable inner packaging structure, the article cannot be well wrapped.

  • FIG16 shows a schematic diagram of the use of a foldable inner packaging structure according to an exemplary embodiment of the present disclosure.
  • the article when an article is placed on the foldable inner packaging structure of the present embodiment and pressure is applied, the article will press down the close-laid unit located below it, and the close-laid unit located below the article will be crushed due to the pressure. And due to the existence of the weak part, the wall of the close-laid unit below the edge of the article will be torn from its weak part.
  • the wall of the close-laid unit directly below will be crushed and folded, and the wall that has been crushed and folded will gradually increase the force required for further crushing due to the increase in area after folding and the stacking effect, and thus can play a good supporting role.
  • the crushing and spreading in the horizontal direction is avoided, so that the close-laid unit separated from the crushed close-laid unit will still maintain its original shape due to the structural stability of the close-laid unit itself, thereby forming a containing space that is basically close to the shape of the article to wrap the article.
  • a good packaging of the article can be formed.
  • the densely packed structure is crushed in the vertical direction when subjected to pressure to form a concave portion for accommodating the product.
  • the arrangement of the weak portion on the wall of the densely packed structure prevents the crushing and spreading of the densely packed structure in the horizontal direction, so that there will be a clear tearing zone between the densely packed units under pressure and the densely packed units not under pressure, thereby forming a good wrapping of the article.

  • the honeycomb dense-paved structure of the embodiment of the present disclosure is simple in structure, easy to manufacture and very easy to use. It is only necessary to press the items into the honeycomb dense-paved structure, and there is no restriction on the shape of the items. After pressing different items, the dense-paved units that are not under pressure separate the items, so that the items can be independently protected.
  • the holes 24 are arranged in a plurality and are arranged in a gradient in the height direction of the wall. Specifically, the size of the holes gradually decreases from the upper end to the lower end of the wall. A hole with a larger size means a lower strength here, that is, it is more likely to tear. Therefore, the holes with a decreasing size gradient in the height direction mean that the crushing force and tearing force of each layer of densely laid units also increase in a gradient. Therefore, under the action of the same pressure, the densely laid units above will be more likely to be crushed first, while the densely laid units below will require a greater force to be crushed later.
  • the upper part of the densely laid unit that first contacts the article is crushed first, and it is also easier to tear and separate from the surrounding densely laid units.
  • the already crushed densely laid units will also fold up, and combined with the smaller holes below, it takes a greater force to crush the densely laid units below.

Description

可折叠包装盒和可折叠包装盒组件以及包装结构件 技术领域
本公开总体上涉及包装技术领域，并且更具体地，涉及由一种可折叠包装盒和可折叠包装盒组件以及包装结构件。
背景技术
目前，随着电子商务和线下零售业务的快速发展，无论是消费者还是品牌方，都对物品保护和可持续发展提出了更多的要求。通常来说对于物品的包装要求对物品进行良好的支撑和缓冲保护，并且提供消费者良好的开启体验。在线下零售场景中，单件或者多件物品在礼盒中往往需要固定位置摆放，电商包装场景中，当一件或者多件物品需要在一个包装箱中运输时，为了保证物品在运输过程中不被损坏，期望对于各个物品的包装是彼此独立的，避免物品与包装盒或者不同物品之间相互影响。
传统包装形式往往使用预先成型好的包装结构件(例如纸内卡或者塑料内卡)，然后将成型好的包装结构件放入包装盒体中，以利用包装结构件实现物品在包装盒体中的固定摆放。传统包装形式中，包装结构件和包装盒体为彼此分离的两个部件，使用时需要分别对两者进行操作和装配。考虑到电子商务和礼盒类业务的大量需求，包装结构件和包装盒体的较低的制造成本，更加环保的材料以及更加灵活适应不同物品尺寸的结构也是所期望的。因此，当前对于物品的包装结构件和包装盒体具有持续改进的需求。

具体实施方式
下面将参照附图来详细描述本公开的各个示例性实施例。应注意到：以下对各个示例性实施例的 描述实际上仅仅是说明性的，绝不作为对本公开及其应用或使用的任何限制。本领域技术人员将会理解，这些实施例仅仅说明可以用来实施的本公开的示例性方式，而不是穷尽的方式。此外，除非另外具体说明，否则在这些实施例中阐述的部件的相对布置、数字表达式和数值不限制本公开的范围。
在说明书中，相同或相似的附图标号指示相同或相似的部件。下述参照附图对本公开实施方式的说明旨在对本公开的技术内容进行解释，而不应当理解为对本公开的一种限制。另外，在下面的详细描述中，为便于解释，阐述了许多具体的细节以提供对本公开示例性实施例的全面理解。然而明显地，一个或多个实施例在没有这些具体细节的情况下也可以被实施。在其他情况下，公知的结构和装置以图示的方式体现以简化附图。
可折叠包装盒的基础构造
本公开提供了一种可折叠包装盒。例如参见图1A至图11D所示的示例性实施例，可折叠包装盒100、100A、100B、100C、100D、100E包括：可折叠外盒体；以及，可折叠内包装结构件9。根据本公开，例如参见图12至图18所示的示例性实施例，可折叠内包装结构件9由多个中空的密铺单元2密铺而形成，密铺单元2的上端部21敞开并且包括多个壁23，其中，多个壁23中的至少一个壁设置有沿高度方向布置的薄弱部24，壁23由可撕裂材料形成。根据本公开，可折叠内包装结构件9结合至可折叠外盒体，以使得可折叠内包装结构件9和可折叠外盒体形成为一体化构造。根据本公开，在可折叠包装盒交付使用之前，可折叠内包装结构件和可折叠外盒体被折叠成处于折叠压缩状态；在可折叠包装盒交付使用后，可折叠内包装结构件和可折叠外盒体被展开成处于立体状态以用作放置物品的包装盒。
术语“折叠压缩状态”是指可折叠包装盒中的可折叠内包装结构件和/或可折叠外盒体在交付使用之前按照其预定设计的折痕被折叠压平以提供较小的体积以便于保存的状态；术语“立体状态”是指可折叠包装盒中的可折叠内包装结构件和/或可折叠外盒体在交付使用后按照其预定设计的折痕被展开以提供较大的三维体积以便于用作具有一定容纳体积的包装盒的状态。此外，根据本公开，在可折叠包装盒处于立体状态下，可折叠外盒体的高度等于或大于可折叠内包装结构件的高度。举例而言，在如图1A至图1D、图5A至图5D、图7A至图7D以及图9A至图9D所示的示例性实施例中，可折叠外盒体的高度等于可折叠内包装结构件的高度；而在如图3A至图3D所示的示例性实施例中，可折叠外盒体的高度大于可折叠内包装结构件的高度。
根据本公开，可折叠外盒体和可折叠内包装结构件可以采用相同的材料制成，也可以采用不同的材料制成。制作可折叠外盒体和/或可折叠内包装结构件的材料包括但不限于纸、塑料、塑料板、瓦楞纸板或牛皮纸等。

可折叠内包装结构件的各种示例性实施例
本公开提供的可折叠包装盒中，可折叠内包装结构件由多个中空的密铺单元密铺而形成，所述密铺单元的上端部和下端部敞开并且包括多个壁，其中，所述多个壁中的至少一个壁设置有沿高度方向布置的薄弱部，所述壁由可撕裂材料形成。
图12是根据本公开的一个示例性实施例的可折叠包装盒中的可折叠内包装结构件9的立体图。如图12所示，本实施例的可折叠内包装结构件9由多个中空的密铺单元2密铺而形成。
针对术语“密铺”，其表示是指将一种或多种平面图形进行拼接使彼此之间不留空隙、不重叠地铺 满一个表面。“密铺单元”表示以一种或多种平面图形构成的基本立体单元，这些基本立体单元彼此拼接从而形成三维立体包装件。密铺单元可以包括例如正三角形密铺单元、正四边形密铺单元、正六边形密铺单元等。包装领域通常采用单一正六边形密铺单元彼此拼接形成蜂窝状结构，但应当理解，如上所述，本公开并不局限于单一正六边形密铺单元，而是可以包括例如正三角形密铺单元、正四边形密铺单元或者其他密铺单元以及其组合。
如图12所述，本实施例的密铺单元2的上端部20并且包括多个壁23。本实施例中，下端部21也敞开，应当理解，下端部可以设置成封闭的。此外，本文中对于方向性术语(例如上和下)的使用是相对应的，取决于例如使用状态等相对应的方向性术语可以反转。三个壁交汇之处形成棱25。图12所示的实施例中密铺单元2设置成单一正六边形密铺单元或者蜂窝状单元，因此密铺单元2包括六个壁。通过多个壁，密铺单元形成被多个壁包围的中空结构，如此设置使得可以在保证支撑功能的前提下极大地节省材料，同时在受到挤压或者冲击时也具有比较良好的缓冲功能。此外，中空结构也使得在一定情况下可以将密铺单元进行折叠，方便进行存储和运输。换句话说，中空结构可以使得可折叠内包装结构件在图12所示的展开结构与未示出的折叠结构之间方便切换。
此外，中空密铺单元2的多个壁23中的至少一个壁设置有沿高度方向布置的薄弱部。在一些示例性实施例中，密铺单元2的多个壁23中的每个壁都设置有前述薄弱部。在另一些示例性实施例中，包装结构件还包括多个额外的中空密铺单元(未图示)，这些额外的中空密铺单元的上端部敞开并且包括多个壁，其中这些多个额外的中空密铺单元的多个壁中的每一个都不具有沿高度方向布置的薄弱部。也就是说，在前述另一些示例性实施例中，构成包装结构件的一些中空密铺单元设有薄弱部，构成包装结构件的另一些中空密铺单元不设有薄弱部。
术语“薄弱部”表示强度(例如抗拉强度或者抗压强度)相对于其余部分进行了减弱处理的部分。当材料受到拉力或者压力时，由于薄弱部处的应力集中，会首先在薄弱部处进行断裂或者撕裂。本实施例中，通过在壁上设置薄弱部，当从上方向下压入物品时，物品正下方的密铺单元将受到下压力，并且位于物品边缘下方的壁将相对于未被下压部分产生拉力，由于薄弱部的存在，此拉力将使得壁被撕裂开来。下文将会针对可折叠内包装结构件受压时密铺单元以及薄弱部的受力进行分析。
本文中，薄弱部还可以包括切除部、撕裂线，或者薄弱部由与壁的其余部分具有不同撕裂强度的材料制成。术语“切除部”表示将壁的材料移除一部分以将其强度。切除部可以包括孔、狭缝等。
本实施例中，薄弱部设置成孔24。应当理解，本文中公开的孔并不表示其一定为圆孔，除非明确指出为圆孔。本公开中，孔可以包括圆孔、椭圆孔、方孔等。对于可折叠内包装结构件来说，能够比较容易地对其进行穿孔处理，因此制造成本相对较低。
图13示出了本公开的一个示例性实施例的可折叠内包装结构件9的主视图，从主视图可以更清楚地看出孔24的分布。如图13所示，本实施例中，孔24设置成多个，并且在密铺单元的高度方向上设置在密铺单元的壁上。本实施例中，孔24设置在密铺单元的所有六个壁上，应当理解，可以根据需要将孔设置在密铺单元的一个或多个壁上。
下面参照图14所示密铺单元的受力分析图来更清楚地解释本申请的可折叠内包装结构件9的工作原理。图14中以单一正六边形密铺单元也即蜂窝密铺单元为例进行分析。
对于密铺单元形成的结构来说，其一大特性是承受轴向载荷时会被压溃。如图14所示，当密铺单元的上方受到压力时，密铺单元将会产生向下折叠或者压溃的趋势。图14中的箭头F表示的力为作用在密铺单元的棱(三壁交汇之处)的向下的压力。
首先将描述在图14中的所有密铺单元上均匀的施加力F时的变形行为。此时，所有密铺单元上方的力F是均匀的，并且当最开始施加压力F时，壁的上部部分将首先被压溃折叠，随后被压溃折叠的上部部分将力传递到壁的中部和下部。壁的压溃折叠后的部分由于压溃折叠后导致受力面积增大，并且压溃折叠后的部分也起到支撑作用，使得如果力需要进一步向下传递，需要施加更大的力。如此，同层的所有密铺单元同步被压溃折叠。实际上，随着压溃的进行，所需要的力的增加速度也是几乎倍增的。由于由蜂窝密铺单元构成的可折叠内包装结构件每层结构相同、近似各向同性，因而结构稳定性好，通常来说需要较大的力才能被压溃，常用物品的重量放置在蜂窝密铺单元上时不易使密铺结构变形，因此，上述结构具有较优良的抗压性能和抗弯性能。
随后将描述在一个或多个密铺单元上施加压力F时的变形行为。由于临近的密铺单元上并未存在向下的压力F，因此，当被施加压力F的密铺单元的壁产生向下的压溃趋势时，相邻棱之间(例如图14所示棱250和251)之间产生相对运动趋势，因而未受压力的棱251将对受压力的棱250产生拉力，也即位于物品边缘下方的壁230上受到如图14所示的远离受力的棱的方向的拉力F1。此拉力F1的存在使得密铺单元被压溃的难度加大，因此，由蜂窝密铺单元构成的可折叠内包装结构件可以适用于多种形状的物品的支撑，无论其面积大于还是小于可折叠内包装结构件的占地面积。
本实施例中，密铺单元的壁由可撕裂材料制成。关于可撕裂材料，可以使用例如纸或芳纶纸。可撕裂材料当承受剪切力时将可能会发生撕裂，因此，在如上所述在一个或多个密铺单元上施加压力时存在未受压力的棱251和受压力的棱251之间的壁230被剪切力撕裂的可能性。但由于密铺单元的壁通常具有一定的支撑功能，因此通常在撕裂之前密铺单元已经发生压溃。密铺单元的壁可以采用单层结构和/或双层结构。以密铺单元的壁使用纸为例，单层结构的壁由一层纸张形成，双层结构的壁由两层纸张彼此粘合形成，切除部可以形成在采用单层结构的壁上，也可以形成在采用双单层结构的壁上，还可以同时形成在采用单层结构的壁和采用双单层结构的壁上。
参照图14，由于受压的密铺单元产生向下移动的趋势，因此拉力F1逐渐由水平产生朝向斜向下的趋势，并且因此在压溃过程中将存在竖向分力，而此竖向分力将导致周围的未受压力的密铺单元也被逐渐压溃，由此使得压溃行为在水平方向上逐渐漫延开来。并且许多情况下这种水平方向上的压溃漫延行为产生在壁撕裂之前，也即在还未达到使得壁撕裂的压力的大小之前已经发生压溃漫延行为。也即受压力的密铺单元和未受压力的密铺单元(本文中受压力和未受压力指的是是否由例如物品等在密铺单元正上方产生的直接压力)之间无法形成明显的撕裂区(最优情况下形成完全竖向的撕裂裂口)，使得物品无法被顺利压入可折叠内包装结构件或者即使物品被压入可折叠内包装结构件时也无法对物品进行良好的包裹，随后将参照图17对包裹行为进行更详细的描述。
申请人发现通过在密铺单元的壁上设置薄弱部，可以使得在密铺单元上施加压力F时，位于物品边缘下方的壁易于撕裂，使得物品边缘下方的密铺单元易于与周围密铺单元分离并且被压溃和折叠。并且从如上对密铺单元的压溃行为的分析可知，密铺单元压溃时下方将逐渐形成更强的支撑，而此时 由于在薄弱部处撕裂开来，防止了水平方向上的压溃漫延行为，并且四周的密铺单元将形成环绕包围结构，也能起到良好的保护作用。
下面将参照图15描述根据本公开的实施例的密铺单元，图15是根据本公开的一个示例性实施例的密铺单元的俯视平面示意图。
图15中加粗部分表示受到压力的密铺单元，并且图15中所示受到压力的密铺单元已经和周围的密铺单元撕裂开来。如图15所示，由于薄弱部的存在，薄弱部将形成应力集中点，当受力时易于产生撕裂，从而便于受力的密铺单元和邻近的密铺单元撕裂开来，最终使得图15所示的受力区域下方的密铺单元与邻近的密铺单元完全撕裂。
图16示出了根据本公开的一个示例性实施例的可折叠内包装结构件的使用示意图。如图16所示，当在本实施例的可折叠内包装结构件上方放置物品并施加压力时，物品将下压位于其下方的密铺单元，位于物品下方的密铺单元因受到压力而被压溃。并且由于薄弱部的存在，物品边缘下方的密铺单元的壁将从其薄弱部撕裂。随着物品的进一步压下或者压溃深度的增加，正下方的密铺单元的壁将被压溃和折叠，而已经压溃和折叠的壁将由于折叠后面积增大以及堆叠作用导致需要进一步压溃的力逐渐增大，并且因此能够起到良好的支撑作用。同时，由于薄弱部的撕裂避免了水平方向上的压溃漫延，使得与发生压溃的密铺单元分离开的密铺单元将由于密铺单元本身的结构稳定性仍然保持其原有形状，从而形成与物品形状基本接近的容纳空间来包裹住物品。由此，能形成对物品的良好包装。
从以上描述可以看出，本实施例中，通过密铺结构使得在竖向方向上受压力时密铺结构在竖向方向上被压溃形成用于容纳产品的凹部。同时密铺结构的壁上薄弱部的设置使得避免了密铺结构在水平方向上的压溃漫延，使得受压力的密铺单元和未受压力的密铺单元之间将存在明确的撕裂区，由此能够形成对物品的良好包裹。
通常蜂窝密铺结构或者蜂窝纸板用于对物体进行支撑作用，申请人通过理论分析和试验验证(下文将对试验进行详细描述)首次发现了可以使用蜂窝密铺结构和蜂窝纸板来包裹或包装物品。并且如上所述由于密铺结构在竖向方向上被压溃，可以将物品压入蜂窝密铺结构并且在压入后底部依然具有良好的支撑。而薄弱部的设置使得避免了密铺结构在水平方向上的压溃漫延，因此可以物品形成非常良好的包裹作用。此外，本公开的实施例的蜂窝密铺结构的构造简单、制造方便并且非常便于使用。只需要通过将物品压入蜂窝密铺结构即可，对于物品形状没有限制，并且压入不同物品后未受压力的密铺单元将物品间隔开来，能够对物品进行独立的保护。
再次返回图12和图13，可以看出，本实施例中孔24设置成多个，并且在壁的高度方向上成梯度设置。具体地，孔的大小从壁的上端部到下端部逐渐减小。更大尺寸的孔意味着此处更低的强度，也即更容易发生撕裂。因此，高度方向尺寸梯度减小的孔意味着每一层密铺单元的压溃力和撕裂力也是梯度增加的。因此，在同样的压力的作用下，上方的密铺单元将更容易首先被压溃，而下方的密铺单元将需要随后更大的力才能被压溃。因此，当物品压下时，最先与物品接触的密铺单元的上部首先被压溃，并且也更容易与周围的密铺单元发生撕裂而分离。随着压溃的进行，已经压溃的密铺单元也将折叠起来，与下方尺寸更小的孔相结合，使得需要更大的力才能压溃下方的密铺单元。由此通过梯度设置的孔使得可以更有效地产生高度方向上的逐层压溃或渐进式压溃效果，避免了在物品压入可折 叠内包装结构件的过程中其他部位同时或者率先产生变形影响整体效果。
本实施例中，梯度设置的孔在壁的高度方向上从上端部开始设置，但并未延伸整个壁的高度，也即并未完全延伸到壁的下端部。应当理解，这并不构成限制，孔的大小、间距以及延伸距离等可以根据需要进行设置。本实施例中，孔沿壁的宽度方向设置在大致中间位置处。应当理解，孔沿壁的宽度方向也可以设置在更靠近任一棱的位置处。
下文中将通过试验来进一步讨论孔的间距、孔的形状、纸的克重、蜂窝状六边形结构的边长等对物品的包装的影响。
首先制备多个可折叠内包装结构件进行准静态压缩试验。本实施例中，可折叠内包装结构件采用蜂窝状结构。关于准静态压缩试验，本试验采用纸箱抗压试验机GK-KY25(可从苏州苏试试验集团有限公司市购)，压缩速度为1mm/min，压缩深度以将物品完全压入蜂窝状结构内部为结束判定依据(此时对应的应力急剧上升)。关于物品，其是高度为约60mm且直径为约60mm的规则圆柱体。如下表1示出了各个样品的基本信息：
表1
首先对参数信息进行解释如下。
关于样品尺寸，其表示可折叠内包装结构件的长宽高尺寸。关于单元布置，其表示单元的纵向排列数量与横向排列数量。关于单元边长，其表示蜂窝结构的六边形的边长。关于最大孔径和最小孔径，其表示孔的最大纵向尺寸和最小纵向尺寸，例如在孔为圆形孔的情况下，最大孔径表示孔的最大直径，最小孔径表示孔的最小直径，在孔为椭圆形孔的情况下，最大孔径表示孔的长轴上的最大直径，最小孔径表示孔的长轴上的最小直径。关于孔间距，其表示相邻的孔的邻近边缘在竖向方向之间的间距。关于纸张克重，其表示构成蜂窝结构的纸的克重。此外，应当注意，上述样品之间的对比应被理解为本申请的不同实施例之间的对比，并非与现有技术之间的对比，下文中的试验对比也应如此理解。
1、首先将讨论单元边长的影响。蜂窝状结构的单元边长主要影响物品被包裹的严密程度，单元边长越小，物品被包裹的效果越好。图6示出了蜂窝状结构的俯视图，图中的阴影部分为位于试验物品下方的蜂窝状单元。
可以看出，在理想情况下，设试验物品的俯视面积为S，完全位于其正下方的蜂窝状单元的个数为m个，其边缘覆盖的蜂窝状单元的个数为n个。当物品被压入蜂窝状结构时，如前所述，导致位于物品边缘下方的蜂窝状单元的壁被撕裂。因此，被压溃和撕裂的蜂窝状单元的数量为(m+n)，这些 蜂窝状单元的面积可以表示为S1，也即S1＝(m+n)xS蜂窝状单元，可以定义α＝S/SS1来表示物品被包裹的严密程度，此外，蜂窝状单元的单元边长被定义为l，根据简单的几何关系，可得：
显然当l越小，则α越大，物品被包裹的严密程度就越高，即被包裹的效果越好。但同时，l不易过小，l过小导致在蜂窝状结构生产时的困难，具体地，例如如果l低于4mm，则在生产过程中，拉伸力便会高于纸所能承受的层间结合力引发纸断裂。
因此，经过理论推导和测试，单元边长设置在5mm-12mm的范围内是合适的。优选地，单元边长可以设置成10mm。上述样品中均采用10mm的长度(有没有一个范围)作为单元边长。
此外，应当理解，本公开并不局限于10mm的边长，也可以根据实际情况采用其他合适长度的单元边长，只要不违背本公开中上述理论。
2、下面将进一步讨论孔的大小、间距和纸的克重对压溃行为和撕裂行为的影响。孔的大小、间距以及纸的克重均会对蜂窝状结构的压溃的容易程度产生影响，因此，三者共同决定了蜂窝状结构的压溃的容易程度。如前所述，本公开中对于物品的包装是通过物品下方的蜂窝状单元的逐层压溃或渐进式压溃以及物品边缘下方的壁(或者物品边缘下方的蜂窝状单元与邻近的蜂窝状单元之间)的撕裂来实现的。孔的尺寸越大，蜂窝状单元的强度就越低，撕裂行为就更容易产生。孔的尺寸越小，蜂窝状单元的强度就越高，撕裂行为就更难以产生。孔的间距越大，蜂窝状单元的强度就越高，撕裂行为就更难产生。孔的间距越小，蜂窝状单元的强度就越低，撕裂行为就更容易产生。纸张克重越小，蜂窝状单元的强度就越低，撕裂行为以及压溃行为都更容易产生。纸张克重越大，蜂窝状单元的强度就越大，撕裂行为以及压溃行为都更难以产生。因此，为了保证撕裂行为以及压溃行为的产生，孔的尺寸不应过小，孔之间的间距不应过大，纸张克重也不易过高，否则一是难以产生压溃，更重要的是压溃时由于蜂窝状单元的撕裂过于困难，在纸还未发生撕裂时蜂窝状结构可能已经被整体压溃(即无法产生逐层压溃效果)，出现物品以外的蜂窝状单元也发生变形的情况，也即压溃行为的水平漫延替代了撕裂行为。但同时，孔的尺寸也不应过大，孔之间的间距也不应过小，同时纸张克重也不应过小，这是为了保证最基本的支撑功能。
首先对比表1中样品A和样品C的测试结果。对于样品A和样品C，除最小孔径及孔间距不同之外，其他条件均相同。具体地，样品A中孔间距设置成7mm，而样品C中的孔间距设置成更大的14mm。试验结果表明样品A能够比较顺利地将物品压入蜂窝状结构，而样品C则难以将物品压入蜂窝状结构。因此，可以看出，孔间距过大将会导致难以产生撕裂行为。
进一步对比样品A和样品B的测试结果。对于样品A和样品B，除了孔的形状以及最大孔径不同之外，其他条件均相同。具体地，样品A中孔的形状为圆形，最大孔径为4.5mm，样品B中孔的形状为椭圆形，最大孔径为5mm。经过测试发现，样品A和样品B都能产生比较良好的压溃行为和撕裂行为。
随后进一步对比样品D和样品E。对于样品D和样品E，除了纸张克重不同之外，其他条件均相 同。具体地，样品D中纸张克重为110g/m2，而样品E中纸张克重为170g/m2。经过测试发现，其他条件合适的情况下，110g/m2和170g/m2克重的纸也都能产生良好的压溃行为和撕裂行为。
如上所示仅列出了5个代表性样品进行了数据对比，申请人通过一系列理论推导以及试验对比后发现如下参数设定。纸的克重范围可以设置在110g/m2和170g/m2之间。进一步地，纸的克重范围可以设置在110g/m2和140g/m2之间。蜂窝状单元的单元边长可以设置在5mm-12mm之间，可选的6mm-15mm之间，可选的7mm-14mm之间，可选的8mm-12mm之间。在蜂窝状单元的单元边长为5mm的情况下，孔的梯度直径范围(也即沿高度方向成梯度减小的最大孔径和最小孔径)可以设置成1mm-2.5mm。在蜂窝状单元的单元边长为12mm的情况下，孔的梯度直径范围可以设置成2mm-5mm。相邻孔的边缘之间的间距可以设置成最大孔径的10％-200％。
接下来将进一步通过试验讨论孔的均匀性、最大孔径与单元边长之间的关系以及开孔的壁的数量对物品的包装的影响。
与前述试验类似，首先制备多个可折叠内包装结构件进行准静态压缩试验。本实施例中，可折叠内包装结构件采用蜂窝状结构。本试验采用纸箱抗压试验机GK-KY25(可从苏州苏试试验集团有限公司市购)，压缩速度为1mm/min，压缩深度以将物品完全压入蜂窝状结构内部为结束判定依据(此时对应的应力急剧上升)。关于物品，其是高度为约60mm且直径为约60mm的规则圆柱体。如下表2示出了各个样品的基本信息：
表2
表2中所示出的同样的参数与表1中所示的参数的含义相同，在此不在赘述。此外，对于最大孔径和最小孔径之间的关系，以样品F为例，最大孔径和最小孔径相同表示壁上所设置的孔的大小均相同，也即设置有等尺寸的孔。开孔壁数量即为蜂窝状单元的六面壁中设置有孔的壁的数量。
首先对比样品F和样品G。对于样品F和样品G，样品F中为等尺寸的孔，而样品G为梯度设置的孔，具体地，沿壁的高度方向从上端部沿向下方向孔的尺寸逐渐减小。通过对比发现，在样品F中，在压入样品时，位于底部的蜂窝状单元也产生压溃现象。相比之下，样品G中通过设置梯度孔，底部的蜂窝状单元并未产生压溃现象。结合前述分析可知，梯度设置的孔使得可以更有效地产生高度方向上的逐层压溃效果，避免了在物品压入蜂窝状结构的过程中底部也产生压溃现象，从而形影响整体效果。
接下来对比样品H和样品I。对于样品H和样品I，除了最大孔径和最小孔径(或者孔径梯度范围)不同之外，其他条件均相同。具体地，样品H中孔径梯度范围为4.5mm-2mm，样品I中孔径梯度范围为3mm-0.5mm。通过对比发现，虽然样品H和样品I都能产生压溃行为和撕裂行为，但样品H中物品周围还产生了一定的蜂窝状单元的坍塌现象，也即压溃行为在水平方向上有小范围的漫延，这使得样品H中的压入物品后的包裹效果较差。而样品I中并未出现水平方向上的压溃漫延，使得样品I中压入物品后的包裹效果更优。
最后将对比样品J和样品K。对于样品J和样品K，除了开孔壁数量不同之外，其他条件均相同。具体地，样品J中六个壁均设置有孔，样品K中仅两个壁设置有孔。通过对比发现，虽然样品J和样品K都能产生压溃行为和撕裂行为，但样品J中物品周围产生了蜂窝状单元的坍塌现象，并且未设置孔的壁的撕裂行为也较差。这表明样品J的压溃行为在水平方向上产生了漫延，这使得样品J中压入物品后的包裹效果较差。而样品K中并未出现水平方向上的压溃漫延，并且由于在六个壁上均设置有孔，撕裂行为也表现良好，使得样品K中压入物品后的包裹效果更优。
通过表2中的试验对比可以看出，梯度设置的孔的压溃行为优于均匀分布的孔的压溃行为，梯度设置的孔可以产生良好的逐层压溃行为，与前述分析一致。此外，申请人通过试验发现，当最大孔径低于蜂窝状单元的单元边长的30％时，易于出现水平方向上的压溃漫延，使得物品周围的蜂窝状单元易变性，导致包裹性较差。当最大孔径大于蜂窝状单元的单元边长的40％时，能够很好地减弱水平方向上的压溃漫延。此外，开孔壁的数量越多，压溃行为和撕裂行为能够更易于发生，并且能够更易于防止水平方向上的压溃漫延。因此，在本公开中，最大孔径设置成大于蜂窝状单元的单元变成的40％。进一步地，优选地在六个壁上设置孔。
此外，本实施例中，通过由纸基可撕裂材料来构造蜂窝状单元，整体结构是100％绿色和可循环的。同时由于纸基可撕裂材料不具有弹性，使得可以形成用于保护物品的永久性结构，能够更好地对物品提供相应的保护。
接下来将给出对本公开另一示例性实施例的可折叠包装盒中的可折叠内包装结构件的描述。该另一个实施例中的可折叠内包装结构件的基本构造和操作与前述一个实施例中的可折叠内包装结构件的基本构造和操作相同。因此，在该另一个示例性实施例中的可折叠内包装结构件中，将省略与前述一个示例性实施例中的可折叠内包装结构件的部件的具有相同功能和构造的部件的描述。
图18示出了根据本公开的可折叠包装盒中的可折叠内包装结构件9的另一个示例性实施例。如图18所示，该另一个示例性实施例与前述一个示例性实施例的主要区别在于可折叠内包装结构件9的底部设置有底部支撑件7。底部支撑件7成平板状并且可拆卸地附接到可折叠内包装结构件9的底部，例如通过粘合等。使用时，可折叠内包装结构件9通过底部支撑件7被放置在地面上，由此增大了与地面的接触面积，使得能够更好地起到支撑作用。当需要对可折叠内包装结构件进行例如折叠运输时，底部支撑件7可以和可折叠内包装结构件9分离并且在使用时附接到可折叠内包装结构件9的底部。
由上可知，根据本公开的一个或多个实施例中提供的可折叠内包装结构件采用蜂窝状结构，所述 蜂窝状结构由多个中空的蜂窝状单元密铺而形成，蜂窝状单元的上端部和下端部敞开并且包括六个壁，其中，六个壁由纸形成并且设置有从上端部沿高度方向朝下尺寸逐渐减小的梯度设置的多个孔。蜂窝状结构保证了其可以起到一定的支撑作用并且在受压力时可以产生压溃行为。壁由纸形成保证了壁在受到拉力时可以产生撕裂行为。孔的设置保证了壁更易于在孔处产生撕裂。而梯度设置的孔则保证了逐层压溃和撕裂行为的发生，减少或者避免了水平方向上的压溃漫延。
根据本公开的可替换实施例，如图19A所示，本公开提供另一种可折叠内包装结构件9，相比于图16中所示的实施方案，该方案以另一个方向(即：垂直于图16中的摆放方向)放置，其中多个中空的密铺单元2中的多个壁23中的至少另一个壁23设置有横向薄弱部80。例如，设置有横向薄弱部80的壁可以是形成多个中空的密铺单元2中的位于外围侧的中空的密铺单元2的壁。根据一些实施例，横向薄弱部80可以构造成沿垂直于高度方向的方向布置的至少一条横切线80。在图19A示的实施例中，横切线80沿垂直于密铺单元高度方向的方向贯穿包装结构件9的所有多个中空的密铺单元2，即：图示三层中空密铺单元均有至少一个壁被横切线所切。如图19B所示，在可折叠包装盒包括可折叠外盒体10以及如图19A所示的包装结构件2的示例中，当将物品P放置在包装结构件2的上方并施加压力时，物品将下压位于其下方的密铺单元，位于物品下方的密铺单元因受到压力而被压溃。。在未图示的实施例中，横切线80也可以沿垂直于密铺单元高度方向的方向不贯穿所有密铺单元2，例如，仅贯穿50％的密铺单元，剩余50％的密铺单元的壁上不具有该横切线，即：假设共有10层密铺单元，横切线80仅沿垂直于密铺单元高度方向的方向裁切5层密铺单元2的壁，而不裁切剩余5层密铺单元2的壁。这样，当物品沿着横切线被压入到包装结构件中，上面5层密铺单元被压缩，而下面5层密铺单元不被压缩，从而为物品的包装保护带来良好的缓冲性。需要说明的是，除非在结构上和/或功能上存在冲突，以如图19A和19B所示的可替换实施例中所描述的可折叠内包装结构件9的构造也可以结合到图1至图18所示的各种示例性实施例中。举例而言，在结合方案中，内包装结构件9的位于中间的密铺单元2可以采用图1至图18所示的各种示例性实施例所描述的切除部设计，而位于外围侧的密铺单元2采用图19A和19B所示的可替换实施例中所描述的横切线设计。
本文中描述的尺寸和值不应被理解为严格限于所引用的精确数值。相反，除非另有说明，否则每个尺寸旨在表示所列举的值和围绕该值的功能上等效的范围。例如，公开为“10mm”的尺寸旨在表示“约10mm”。
虽然本公开的一些实施例已被显示和说明，本领域普通技术人员将理解，在不背离本公开的原则和精神的情况下，可对这些实施例做出改变，本公开的范围以权利要求和它们的等同物限定。
