Description

包装盒
技术领域
本实用新型涉及包装领域，更具体地说，涉及一种包装盒。
背景技术
目前在许多场合都会使用包装盒，例如在打包食物时、进行食品包装时、进行医用物品的包装时，等等。由于包装盒可能用来装饭菜等食物，因此要求其密封性好，能避免包装盒的盖子意外打开，并能在一定程度上防止汤汁洒出。但目前常用的包装盒的密封性能还不能满足要求。
在打开包装盒时，需要用手用力向上掰开包装盒的盖子边缘，再将盖子向上打开。在此过程中，由于包装盒的结构不利于操作，可能在打开的过程中导致包装盒内的食物等内容物洒出。
此外，由于许多包装盒是一次性使用的，大多厚度较薄，其四周的薄壁并不能保证强度，导致包装盒在受到外力时很容易变形破碎。
实用新型内容
本实用新型要解决的技术问题在于，针对现有技术中的包装盒密封性不能满足要求的缺陷，提供一种包装盒，其密封性较好。
本实用新型解决其技术问题所采用的技术方案是：构造一种包装盒，包括顶部开口的盒体、以及连接在所述盒体顶部且能打开的盖子，所述盒体包括底壁、以及连接在所述底壁周缘的侧壁，所述侧壁的顶端形成向外翻折的弧形顶缘；
所述盖子包括顶壁、以及连接在所述顶壁周缘的扣接部分；
在所述扣接部分上形成凸肋，所述扣接部分与所述弧形顶缘配合且所述凸肋挡在所述扣接部分的下缘处。
根据本实用新型所述的包装盒，在所述侧壁的相对两侧，设置有向内凹进的凹处。
根据本实用新型所述的包装盒，所述凹处呈上窄下宽的梯形。
根据本实用新型所述的包装盒，在所述盖子上，设置有水平向外延伸的握持部。
根据本实用新型所述的包装盒，所述弧形顶缘包括与所述侧壁连接且向上延伸的第一内侧部、一端与所述第一内侧部连接的第一弧形部、以及与所述第一弧形部的另一端连接的第一外侧部，所述第一弧形部向上凸出，所述第一外侧部从所述第一弧形部向下延伸。
根据本实用新型所述的包装盒，在所述弧形顶缘的第一内侧部与所述侧壁的连接处形成台阶。
根据本实用新型所述的包装盒，所述扣接部分包括从所述顶壁周缘向上延伸的第二内侧部、一端与所述第二内侧部连接的第二弧形部、以及与所述第二弧形部的另一端连接的第二外侧部，所述第二弧形部向上凸出，所述第二外侧部从第二弧形部向下延伸。
根据本实用新型所述的包装盒，所述凸肋的数量为多个，设置在所述接部分的第二外侧部上，且朝向所述第二内侧部凸出。
根据本实用新型所述的包装盒，在所述第二内侧部下端，形成朝向所述第二外侧部凸出的环形凸起，所述环形凸起围绕所述第二内侧部且与所述盒体的弧形顶缘接触。
根据本实用新型所述的包装盒，在所述顶壁与所述扣接部分之间形成向下凹进的过渡部，所述过渡部环绕在所述顶壁周围。
实施本实用新型的包装盒，具有以下有益效果：有效改善了密封性，其结构利于操作，且强度也得到了改善。

具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本实用新型，并不用于限定本实用新型。
图1是本实用新型中包装盒10的盒体100的立体图；图2A是本实用新型中包装盒10的盒体100的另一立体图；图2B是本实用新型中包装盒的盒体的截面图；如图1和图2A、2B所示，包装盒10包括顶部开口的盒体100、以及连接在盒体100顶部并将其封闭的盖子200(在图3中示出)。
盒体100包括底壁101、以及连接在底壁101周缘的侧壁102，侧壁102环绕底壁101。在图示的实施例中，底壁101呈带有圆角的长方形，侧壁102连接在底壁101上且围绕底壁101，使得整个包装盒10大致呈立方体形状。但本实用新型不限于此，底壁101也可以呈其他形状，例如圆形，此时包装盒大致呈圆柱状。
侧壁102的顶端形成向外翻折的弧形顶缘103，该弧形顶缘103包括与侧壁102连接且向上延伸的第一内侧部103a、一端与第一内侧部103a连接的第一弧形部103b、以及与第一弧形部103b的另一端连接的第一外侧部103c，第一弧形部103b向上凸出，第一外侧部103c从第一弧形部103b向下延伸。为了增加强度，在弧形顶缘103的第一内侧部103a与侧壁102的连接处形成台阶104。为了进一步增加弧形顶缘103的强度，在弧形顶缘103上，设置有从第一内侧部103a和第一弧形部103b向外延伸的肋条103d。
在侧壁102的相对两侧，设置有向内凹进的凹处102a。该凹处102a可以呈上窄下宽的梯形，但也可以是其他合适的形状。凹处102a的设置使得使用者在握持盒体100时会更加方便。此外，凹处102a可以增加盒体100的强度，降低盒体100在受到外力时发生变形、破损的几率。
图3是本实用新型中包装盒10的盖子200的立体图；图4是本实用新型中包装盒10的盖子200的截面图；图5是图4的局部放大图。如图3至图5所示，盖子200包括顶壁201、以及连接在顶壁201周缘的扣接部分202。该扣接部分202包括从顶壁201周缘向上延伸的第二内侧部202a、一端与第二内侧部202a连接的第二弧形部202b、以及与第二弧形部202b的另一端连接的第二外侧部202c。第二弧形部202b向上凸出，第二外侧部202c从第二弧形部202b向下延伸。
为了改善密封性，在第二内侧部202a下端，形成朝向第二外侧部202c凸出的环形凸起202d，该环形凸起202d围绕第二内侧部202a。当盖子200的扣接部分202扣接在盒体100的弧形顶缘103上时，该环形凸起202d与盒体100的弧形顶缘103的第一内侧部103a接触，以改善密封性能(参见图6、7)。
为了使盖子200与盒体100之间的配合顺畅，在顶壁201与扣接部分202之间形成向下凹进的过渡部203，过渡部203环绕在顶壁201周围。该过渡部203优选地呈向下凹进的弧形，且最低点低于顶壁201。
该过渡部203的作用在于，当盖子200的扣接部分202扣接在盒体100的弧形顶缘103上时，过渡部203位于弧形顶缘103的内侧，这可以改善包装盒10的密封性。
在扣接部分202的第二外侧部202c上，设置有朝向第二内侧部202a凸出的多个凸肋202e，这些凸肋202e均水平延伸，可以呈半圆柱形等形状，其表面圆滑以方便扣合。这多个凸肋202e的上缘与扣接部分202的第二弧形部202b之间的距离A等于或稍大于盖子200的扣接部分202的第一外侧部103c的下缘到第一弧形部103b的顶面之间的对应距离。也就是说，当盖子200扣接到盒体100上时，弧形顶缘103的第一外侧部103c会挤压扣接部分202上的凸肋202e，使得扣接部分202的第二外侧部202c向外轻微变形。当扣接到位后，凸肋202e挡在盒体100的第一外侧部103c的下缘处，使得盖子200不会轻易脱落，如图6和图7所示。这种结构有效地改善了包装盒10的密封性。
回到图3，在盖子200上，设置有从第二外侧部202c水平向外延伸的握持部205。该握持部205可以呈弧形。在打开盖子200时，可以握住握持部205，从而很方便地将盖子200打开。
本实用新型的包装盒10有效改善了密封性，其结构利于操作，且强度也得到了改善。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
