Description

可替换式化妆品容器以及制造该容器的模具 技术领域
本申请涉及化妆品技术，具体涉及一种可替换式化妆品容器以及制造该容器的模具。
背景技术
化妆品是日化用品中常见的产品，一般包括外壳以及置于该外壳内的内胆。在生产的过程中，内胆和外壳一般为分体部件，组装时将两者固定连接在一起。当内胆中的化妆物料使用完毕后，直接将容器丢弃，造成了资源的浪费，也不符合环保的要求。
发明内容
为了克服上述缺陷，本申请提供一种可替换式化妆品容器，该容器中的内胆可以替换，且内胆与外壳之间通过过盈配合而固定在一起，因此容器中除内胆外的其他部件可以重复使用，减少了资源的浪费，且内胆拆装便利，便于使用。

实施例：如图1-11所示，一种可替换式化妆品容器，包括内胆10和外壳20，内胆10包括具有镂空的上开口端11和下封闭端12，上开口端11径向向外延伸形成翻边14，外壳20包括具有镂空的顶端21和具有镂空的底端22，内胆10安装于外壳20内，翻边14扣合于顶端21,顶端21与内胆10过盈配合，下封闭端12位于底端22的内侧。
如图5-7所示，内胆10为上端开口、下端封闭、内部中空的筒状结构。内胆10中内部中空形成的容置槽用于存放化妆料体或者护肤料体，上述料体可以是膏状物。上开口端11沿圆周方向形成一圈封闭的翻边14，如图9和图10所示，翻边14与内胆10之间具有一定的间隙。可选地，上开口端11先径向向外延伸、再轴向向下延伸形成纵向截面类似“L”型的翻边14；同样参考图5-7所示，外壳20为上下两端开口、内部中空的筒状结构，外壳20中内部中空形成的容置槽用于放置内胆10，外壳20与内胆10的结构 类似，可为近似圆柱体、圆台体、多面体等形状。当内胆10安装于外壳20时，外壳20的顶端21插入翻边14与内胆主体之间的间隙内，通过内胆10与外壳20的顶端21之间过盈配合使两者紧密结合，所谓内胆10与外壳20的顶端21过盈配合：可以是顶端21的外侧壁与内胆10过盈配合，也可以是顶端21的内侧壁与内胆10过盈配合；还可以是顶端21的内、外侧壁皆与内胆10过盈配合；当内胆10中的料体使用完毕后，从外壳20的底端22的镂空处使内胆10的下封闭端12受到向上的外力，内胆10向上移动而脱离外壳20，再装入新的内胆10即可完成内胆的更换，操作十分方便。
本申请中内胆通过翻边扣合于外壳的顶端，再通过内胆与外壳20的顶端21过盈配合于外壳而使两者紧密结合，因此安装和拆卸非常方便，而且内胆和外壳的结构简单，制造成本低，易于工业化生产；本申请中内胆可以被替换，因此除了内胆外的其他部件都可重复使用，减少了资源浪费，符合环保要求；当内胆装入外壳后，内胆的下封闭端位于外壳的底端的内侧，因此内胆的下封闭端不与外界接触，降低了内胆破损的可能性。
如图2和图8所示，顶端21沿轴向方向延伸形成插片23，翻边14扣合于插片23上，且插片23与内胆10过盈配合，内胆10包括内胆主体和翻边14。顶端21上表面沿轴向向上延伸形成插片23，插片的厚度小于顶端的厚度，插片23插入翻边14内且翻边14置于顶端21上，将内胆10除了翻边14的部分定义为内胆主体，则内胆10由内胆主体和翻边14组成，插片23与内胆10之间过盈配合存在以下三种实施方式：插片23的外侧壁与内胆10的翻边14过盈配合；或插片23的内侧壁与内胆主体过盈配合；或插片23的内、外侧壁分别与内胆主体、翻边过盈配合。
如图2所示，在一实施方式中，插片23的外侧壁沿径向向外延伸形成凸筋24，凸筋24与翻边14的内侧壁过盈配合，或翻边 14的内侧壁沿径向向内延伸形成凸筋24，凸筋24与插片23的外侧壁过盈配合。即插片23与翻边14之间通过凸筋24过盈配合，可选地，插片23或翻边14沿圆周方向形成一圈或多圈凸筋24,亦或者，插片23或翻边14沿圆周方向形成若干相互间隔的凸筋24；即插片23与翻边14之间通过一圈凸筋或者若干圈平行的凸筋24过盈配合；也可将凸筋24设计为相互间隔的若干段，而不是一整圈。
在另一实施方式中，插片23的内侧壁沿径向向内延伸形成凸筋24,凸筋24与内胆主体的外侧壁过盈配合,或内胆主体的外侧壁沿径向向外延伸形成凸筋24,凸筋24与插片23的内侧壁过盈配合。即插片23与内胆10靠近上开口端11处的外侧壁通过凸筋24过盈配合；可选地，插片23或内胆10沿周向形成一圈或者若干圈平行的凸筋24,亦或者，插片23或内胆10沿周向形成若干相互间隔的凸筋24。
在又一实施方式中，可替换式化妆品容器中设置有第一子凸筋和第二子凸筋，第一子凸筋用于令插片23的内侧壁与内胆主体的外侧壁过盈，第二子凸筋用于令插片23的外侧壁与翻边14的内侧壁过盈。具体存在以下四种情况：
第一种情况：插片23的内侧壁沿径向向内延伸形成第一子凸筋，插片23的外侧壁沿径向向外延伸形成第二子凸筋；
第二种情况：插片23的内侧壁沿径向向内延伸形成第一子凸筋，翻边14的内侧壁沿径向向内延伸形成第二子凸筋；
第三种情况：翻边14的内侧壁沿径向向内延伸形成第二子凸筋，内胆主体的外侧壁沿径向向外延伸形成第一子凸筋；
第四种情况：内胆主体的外侧壁沿径向向外延伸形成第一子凸筋，插片23的外侧壁沿径向向外延伸形成第二子凸筋。
即在上述四种情况下，插片23的内、外侧壁通过第一子凸筋、 第二子凸筋分别与内胆主体、翻边14过盈配合。
如图1所示，内胆10的外侧壁与外壳20的内侧壁之间设有空隙15；即外壳20除了插片23与内胆10紧密配合外，外壳20的其他部位与内胆10之间具有空隙15，这样，两者的接触面积很小，减少了安装和更换内胆时的阻力，便于内胆的拆装。而如果直接通过内胆10和外壳20之间大面积贴合并过盈接触或摩擦接触，因接触面积较大，造成内胆安装或拆卸于外壳时阻力很大，使用非常不便，而且对内胆和外壳两者的尺寸精确要求高，提高了加工成本。
如图1所示，下封闭端12的底面与底端22的底面之间的距离为L，且L为1.5±1mm。将内胆的下封闭端12设计于外壳的底端22内部，并将下封闭端的缩进量控制在1.5mm左右，既可保证内胆的下封闭端不会接触到外界，又尽可能地提高了内胆的容积。
可选地，外壳20为透明外壳，底端22上贴合透明的保护膜，保护膜将底端22上的镂空密封。外壳20可采用高级的材料制成，如高档的金属、塑料，可替换件的内胆10可采用普通的塑料制成，这样既可以保证化妆品容器的品质，又可适当地降低成本。将外壳的底端22贴上透明的保护膜，可以防止外部的灰尘进入外壳与内胆之间，保证了化妆品容器的洁净度。
可选地，内胆10的外侧壁沿轴向形成卡槽，外壳20的内侧壁沿轴向形成能够插入卡槽的卡筋，或外壳20的内侧壁沿轴向形成卡槽，内胆10的外侧壁沿轴向形成能够卡入卡槽的卡筋。在外壳20与内胆10之间的圆周方向通过卡槽与卡筋相互限定，从而进一步防止内胆10相对于外壳20发生转动，便于使用。
如图1-7所示，本申请还包括外盖30、垫片40和盖片50，上开口端11上设有缺口13，盖片50置于缺口13上而将上开口端11密封，外盖30可拆卸地盖合于外壳20，外盖30与盖片50之间设有垫片40，且垫片40贴合于外盖30的内侧。内胆10置于外壳20 内，且两者之间通过凸筋24过盈配合，盖片50盖合于内胆10的上开口端11并置于缺口13上，外盖30的内侧壁设有内螺纹，外壳20的外侧壁设有外螺纹，外盖30通过内外螺纹锁紧于外壳20上，外盖30与盖片50之间设有垫片40以进一步密封内胆10，同时还可减少外盖30与内胆10之前的磨损。
本申请还提供有一种模具，该模具用于制造上述的可替换式化妆品容器。本申请中的内胆10、外壳20和外盖30可分别通过模具单独成型，成型后再进行组装。内胆和外壳的结构简单，因此模具制造成本低，易于产品的工业化生产。
需要说明的是，上述一种模具可以根据实际生产情况理解为若干套模具，每一套模具用于注塑成型可替换式化妆品容器中的一个部件，各个部件通过组装形成可替换式化妆品容器。例如，一种模具可以包括第一模具、第二模具、第三模具、第四模具和第五模具。其中，第一模具用于生产内胆10，第二模具用于生产外壳20，第三模具用于生产外盖30，第四模具用于生产垫片40，第五模具用于生产盖片50。在另一种可能的实现方式中，垫片40采用非注塑工艺制造，则本申请中指明的一种模具可以包括第一模具、第二模具、第三模具和第五模具。
需要说明的是，模具可以根据实际制造情况自由组合装配，能够注塑制造本申请所公开的可替换式化妆品容器的模具，均在本申请的保护范围中。
应当指出，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
