Description

一种纸塑结合的包装盒
技术领域
本实用新型涉及一种包装盒，尤其是涉及一种纸塑结合的包装盒。
背景技术
目前盛装液体或粉末的包装盒大多为金属包装盒或PE包装盒，随着环保意识的提升，纸质包装盒越来越受到关注，然而，纸质包装盒存在边密封问题，而且其造型也由于材质的原因受到很大局限(大多只能是方方正正的造型)，以上种种都大大限制了纸质包装盒的应用。
实用新型内容
本实用新型的目的就是为了克服上述现有技术存在的缺陷而提供一种纸塑结合的包装盒。
本实用新型的目的可以通过以下技术方案来实现：
一种纸塑结合的包装盒，为翻盖包装盒，包括：
盒盖卡纸，
盒身卡纸部，由多个卡纸围成，具有上沿口，
注塑成型的一体式塑料框架，用于连接盒盖卡纸和盒身卡纸部，由通过铰链塑料件连接的盒身塑料件和盒盖塑料件组成，盒身塑料件由设置于盒身卡纸部的卡纸缝隙处的盒身塑料件本体以及包裹于盒身卡纸部上沿口处的上沿口塑料件组成，盒盖塑料件包裹于盒盖卡纸周围，上沿口塑料件和盒盖塑料件通过扣合连接实现包装盒的密封。
优选地，所述的盒身卡纸部由用于形成侧壁的四个侧壁卡纸以及用于形成盒底的盒底卡纸组成，盒身塑料件本体填充于卡纸缝隙处，并包裹于卡纸缝隙处内外两侧。
优选地，所述的盒身塑料件本体包裹于卡纸缝隙处内侧的宽度大于包裹于卡纸缝隙处内侧的宽度。包装盒的内侧面是迎着内容物的一面，因此相邻两个卡纸缝隙处内侧面的塑料件的宽度较宽能够有效避免内容物润湿卡纸，提高密封性能。
优选地，所述的盒身卡纸部的横截面呈椭圆矩形状。所述的椭圆矩形是在圆角矩形基础上，将四条边向外微微弯曲形成。
优选地，所述的盒盖卡纸的形状与盒身卡纸部的横截面形状相匹配。
优选地，包装盒密封时，所述的盒盖塑料件扣合于上沿口塑料件上，并通过卡扣连接。
优选地，所述的盒身塑料件本体还包括盒底支撑筋。
与现有技术相比，本实用新型具有以下有益效果：
(1)在切面处卡纸被塑料包裹，卡纸不会被液体浸润，包装盒的密封也是通过塑料件(上沿口塑料件和盒盖塑料件扣合连接)实现的，密封性能好。
(2)一体式塑料框架配合不同材料的卡纸和精美的印刷可具有多变的亮丽的外观，克服了现有卡纸盒造型单一的缺陷。
(3)纸塑结合的包装盒较卡纸盒具有更高的强度，保证强度及密封性能的同时，大大节省了塑料的用量，不仅降低了成本，而且更加环保。
附图说明

图2为本实用新型的包装盒封闭状态的示意图；
图3为本实用新型的包装盒封闭状态的仰视示意图。
图中，1为盒盖卡纸，21为侧壁卡纸，22为盒底卡纸，31为盒身塑料件本体，32为上沿口塑料件，33为盒底支撑筋，4为盒盖塑料件，5为铰链塑料件。
具体实施方式
下面结合附图和具体实施例对本实用新型进行详细说明。
实施例1
一种纸塑结合的包装盒，如图1～3所示，为翻盖包装盒，包括盒盖卡纸1、盒身卡纸部及注塑成型的一体式塑料框架，其中：盒身卡纸部由多个卡纸围成，具有上沿口；注塑成型的一体式塑料框架用于连接盒盖卡纸1和盒身卡纸部，由通过铰链塑料件5连接的盒身塑料件3和盒盖塑料件4组成，盒身塑料件3由设置于盒身卡纸部的卡纸缝隙处的盒身塑料件本体31以及包裹于盒身卡纸部上沿口处的上沿口塑料件32组成，盒盖塑料件4包裹于盒盖卡纸1周围，上沿口塑料件32和盒盖塑料件4通过扣合连接实现包装盒的密封。本实施例的包装盒密封时，盒盖塑料件4扣合于上沿口塑料件32上，并通过卡扣连接，如图2所示。
本实用新型中，优选盒身卡纸部由用于形成侧壁的四个侧壁卡纸21以及用于形成盒底的盒底卡纸22组成，盒身塑料件本体31填充于卡纸缝隙处，并包裹于卡纸缝隙处内外两侧。为了更好的避免卡纸去切面润湿，盒身塑料件本体31包裹于卡纸缝隙处内侧的宽度大于包裹于卡纸缝隙处内侧的宽度(如图1所示)。盒盖卡纸1的形状与盒身卡纸部的横截面形状相匹配。本实施例中，盒身卡纸部的横截面呈椭圆矩形状。椭圆矩形在圆角矩形基础上将四条边向外微微弯曲形成。由于盒底要承受内容物的全部重量，因此，本实用新型的盒身塑料件本体还包括盒底支撑筋，设置于盒底卡纸22底部，以增强盒底强度，如图3所示。
本实施例通过注塑成型的塑料在四个转角处、底部周围、沿口周围以及盖子周围，通过一体成型的铰链将盒身和盒盖组合起来，产品盖上后具有密封性。与现有产品相比，纸塑结合的包装盒较卡纸盒具有更高的强度；在切面处卡纸被塑料包裹，卡纸不会被液体浸润；配合不同材料的卡纸和精美的印刷可具有多变的亮丽的外观。
上述对实施例的描述是为便于该技术领域的普通技术人员能理解和使用实用新型。熟悉本领域技术的人员显然可以容易地对这些实施例做出各种修改，并把在此说明的一般原理应用到其他实施例中而不必经过创造性的劳动。因此，本实用新型不限于上述实施例，本领域技术人员根据本实用新型的揭示，不脱离本实用新型范畴所做出的改进和修改都应该在本实用新型的保护范围之内。
