Description

一种防止儿童打开的自封袋 技术领域
本实用新型涉及包装袋技术领域，具体涉及一种防止儿童打开的自封袋。
 背景技术
目前，由于凹凸自封袋具有以下特点：（1）封口严密，可有效防止污染、防潮、防水、防虫、防止东西散落；（2）轻轻一按便会密封的严严实实的，无毒无味，柔韧性好，封合随意，非常方便；（3）价格低，可以重复使用，节能环保。因此现已成为日常生活中不可缺少的日常用品，广泛用于产品包装，存放食品、饰品、药品、化妆品、冷冻食品、邮品等行业。
 技术问题
大多数凹凸自封袋封装时采用凹条和凸条互相扣合的方式，将物品封装在袋体内，自封条上安装有拉扣，拉动拉扣即可将自封袋打开和封装，但是，拉扣安装在自封条上占有一定的长度，因此并不能彻底将自封袋内密封，同时对于儿童来说用手轻轻拉动拉扣就可以完全打开自封袋，对于包装了非食品类的儿童不宜碰触的物品，很容易发生儿童误食的事故。
 技术解决方案
为了解决上述现有技术的问题，本实用新型提供一种防止儿童打开的自封袋，确保自封袋能完全密封，同时防止儿童打开，造成危险事故。
本实用新型的目的可通过下列技术方案来实现：一种防止儿童打开的自封袋，包括袋体，所述袋体开口处的两个内侧面分别热合连接有第一自封条和第二自封条，所述第一自封条面上设有互相平行的凹条和凸条，所述第二自封条面上设有互相平行的凸条和凹条，所述第一自封条和所述第二自封条通过凹条与凸条互相扣合的方式密封连接；所述第一自封条的四周均与所述袋体热合连接，所述第二自封条的下边线与两侧边均与所述袋体热合连接；所述第一自封条上设有矩形的活页，所述活页的上边线与所述第一自封条连接，所述活页的下边线位于所述凹条与所述凸条的中间，并且所述活页的两侧边线与下边线与所述第一自封条通过易撕线连接。
优选的，所述袋体上对应的所述活页重合的位置设置有相同的易撕线。掰开活页时，活页沿着易撕线从第一自封条上裂开，同时活页对应袋体的位置也沿着易撕线裂开。
优选的，所述活页与所述第一自封条的其中一个端部距离为5-8cm。
优选的，所述第一自封条上的所述凹条位于所述凸条的上方，所述活页的两侧边的易撕线穿过所述凹条；相对应的，所述第二自封条上的所述凸条位于所述凹条的上方。
优选的，所述第二自封条的下边线的热合线位于所述凹条的下方。第一自封条与第二自封条上的凸条与凹条互相扣合后，将袋体的开口向两边拉扯时，第二自封条与第一自封条的扣合处在拉扯力的作用下向第一自封条倾斜，又因第二自封条的下边线与袋体热合连接，因此紧抓住袋体的开口向两边拉扯很难将自封袋的袋口打开。
本实用新型使用时：将袋体与第一自封条、第二自封条按照热合工艺热合加工完成后，在袋体内装入物品，然后通过两个自封条上相对应的凸条与凹条相互扣合将自封袋袋口密封；由于第二自封条的上边线与袋体属于分离状态，因此在封口状态下将袋口拉扯打开时，扣合的位置向第一自封条倾斜，又因为第二自封条的下边线与袋体热合连接，因此单纯的拉扯自封袋的袋口很难或者不能将袋子打开，因此能防止儿童将自封袋打开，使袋子具有安全性；当需要打开自封袋的袋口时，先将活页向外掰开，此时活页与对应位置的袋体部位均沿着易撕线裂开，将活页上附带的部分凹条从扣合处掰开，活页被掰开后在第一自封条上形成一个窗口，窗口的两侧边相当于新的扣合连接的端面处，因此从窗口打开袋口时，容易沿着扣合端面打开，如此只有当活页被掰开后才能轻松地将自封袋的袋口打开，具有一定的步骤与技巧，相对于儿童来说打开的步骤方式复杂，因此儿童不易打开；最后，因为活页的易撕线属于一次性结构，在购买新产品等情况时能根据易撕线是否打开判断是否属于新产品，或者自封袋是否使用过，具有一定的鉴别功能。
 有益效果
本实用新型所带来的综合效果包括：本实用新型构造简单合理，使用方便，第二自封条的上边线不与袋体热合连接，当第一自封条与第二自封条扣合后，当儿童向两边拉扯袋口时，扣合的第二自封条向第一自封条倾斜，因此自封条的扣合处不容易拉开，避免儿童将自封袋打开，使自封袋对于儿童来说具有安全性；此外，当成人需要打开自封袋时，先将活页向外掰开，然后沿着活页处的窗口向外将自封条扣合处掰开，从而将自封袋袋口打开，自封袋的打开方式具有一定的方式技巧，因此对于成人，很容易将自封袋打开；此外，活页的易撕线还能能起到一定的自身鉴别作用。

 本发明的最佳实施方式
下面结合附图和实施例进一步说明本实用新型。
实施例
一种防止儿童打开的自封袋，包括袋体1，所述袋体1开口处的两个内侧面分别热合连接有第一自封条2和第二自封条3，在附图中，网格填充线均为热合线，所述第一自封条2面上设有互相平行的凹条4和凸条5，所述第二自封条3面上设有互相平行的凸条5和凹条4，所述第一自封条2和所述第二自封条3通过凹条4与凸条5互相扣合的方式密封连接；所述第一自封条2的四周均与所述袋体1热合连接，所述第二自封条3的下边线与两侧边均与所述袋体1热合连接；所述第一自封条2上设有矩形的活页6，所述活页6的上边线与所述第一自封条2连接，所述活页6的下边线位于所述凹条4与所述凸条5的中间，并且所述活页6的两侧边线与下边线与所述第一自封条2通过易撕线7连接。所述袋体1上对应的所述活页6重合的位置设置有相同的易撕线7。掰开活页6时，活页6沿着易撕线7从第一自封条2上裂开，同时活页6对应袋体1的位置也沿着易撕线7裂开。所述活页6与所述第一自封条2的其中一个端部距离为5-8cm。
所述第一自封条2上的所述凹条4位于所述凸条5的上方，所述活页6的两侧边的易撕线7穿过所述凹条4；相对应的，所述第二自封条3上的所述凸条5位于所述凹条4的上方。所述第二自封条3的下边线的热合线位于所述凹条4的下方。第一自封条2与第二自封条3上的凸条5与凹条4互相扣合后，将袋体1的开口向两边拉扯时，第二自封条3与第一自封条2的扣合处在拉扯力的作用下向第一自封条2倾斜，又因第二自封条3的下边线与袋体1热合连接，因此紧抓住袋体1的开口向两边拉扯很难将自封袋的袋口打开。
本实用新型实施例使用时：将袋体1与第一自封条2、第二自封条3按照热合工艺热合加工完成后，在袋体1内装入物品，然后通过两个自封条上相对应的凸条5与凹条4相互扣合将自封袋袋口密封；由于第二自封条3的上边线与袋体1属于分离状态，因此在封口状态下将袋口拉扯打开时，扣合的位置向第一自封条2倾斜，又因为第二自封条3的下边线与袋体1热合连接，因此单纯的拉扯自封袋的袋口很难或者不能将袋子打开，因此能防止儿童将自封袋打开，使袋子具有安全性；当需要打开自封袋的袋口时，先将活页6向外掰开，此时活页6与对应位置的袋体1部位均沿着易撕线7裂开，将活页6上附带的部分凹条4从扣合处掰开，活页6被掰开后在第一自封条2上形成一个窗口，窗口的两侧边相当于新的扣合连接的端面处，因此从窗口打开袋口时，容易沿着扣合端面打开，如此只有当活页6被掰开后才能轻松地将自封袋的袋口打开，具有一定的步骤与技巧，相对于儿童来说打开的步骤方式复杂，因此儿童不易打开；最后，因为活页6的易撕线7属于一次性结构，在购买新产品等情况时能根据易撕线7是否打开判断是否属于新产品，或者自封袋是否使用过，具有一定的鉴别功能。
本实用新型实施例所带来的综合效果包括：本实用新型实施例构造简单合理，使用方便，第二自封条3的上边线不与袋体1热合连接，当第一自封条2与第二自封条3扣合后，当儿童向两边拉扯袋口时，扣合的第二自封条3向第一自封条2倾斜，因此自封条的扣合处不容易拉开，避免儿童将自封袋打开，使自封袋对于儿童来说具有安全性；此外，当成人需要打开自封袋时，先将活页6向外掰开，然后沿着活页6处的窗口向外将自封条扣合处掰开，从而将自封袋袋口打开，自封袋的打开方式具有一定的方式技巧，因此对于成人，很容易将自封袋打开，同时又能保证自封袋的密封性；此外，活页6的易撕线7还能能起到一定的自身鉴别作用。
本说明书所附图式所绘示的结构、比例、大小等，均仅用以配合说明书所揭示的内容，以供熟悉此技术的人士了解与阅读，并非用以限定本实用新型可实施的限定条件，故不具技术上的实质意义，任何结构的修饰、比例关系的改变或大小的调整，在不影响本实用新型所能产生的功效及所能达成的目的下，均应仍落在本实用新型所揭示的技术内容得能涵盖的范围内。同时，本说明书中所引用的如“上”、“下”、“左”、“右”、“中间”及“一”等的用语，亦仅为便于叙述的明了，而非用以限定本实用新型可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本实用新型可实施的范畴。
以上参考了优选实施例对本实用新型进行了描述，但本实用新型的保护范围并不限制于此，任何落入权利要求的范围内的所有技术方案均在本实用新型的保护范围内。在不脱离本实用新型的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。
