本发明的最佳实施方式
[0028] 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。
[0029] 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包括顶部幵口的盒体 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） 。
[0030] 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 1 01。 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， 此吋包装盒大致呈圆柱状。
[0031] 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。
[0032] 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吋会更加方便。 此外， 凹处 102a可以增加盒体 100的强度， 降低盒体 100在 受到外力吋发生变形、 破损的几率。
[0033] 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 1 0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 2 01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 20 2b、 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。
[0034] 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上吋， 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) 。
[0035] 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。
[0036] 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上吋， 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。
[0037] 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上吋， 弧形顶缘 1 03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 1 03c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。
[0038] 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。 在打幵盖子 200吋， 可以握住握持部 205， 从而很方 便地将盖子 200打幵。
[0039] 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。
[0040] 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。
