Abstract

一种塑料袋，包括袋体（1），袋体（1）的一端为封口端（2），封口端（2）侧的袋体（1）上设有粘接线；袋体（1）的两侧侧壁分别伸入袋体（1）的内部形成折叠区域（10），折叠区域（10）的粘接线呈弧线（5），弧线（5）的两端点位于折叠区域（10）和非折叠区域（11）的交界区域的内边缘的两侧。由于塑料袋折叠区域封口端侧的粘接线呈弧线，使得粘接线处被施力时，力度会被分散开来，不会造成因为力量过于集中而使某处的粘接线断裂，塑料袋连接处裂开的情况发生。因此该塑料袋使用时底部不会轻易发生损坏，提高了实用性。

Description

一种塑料袋
郑重声明
本发明要求了申请日为2016年06月07日、申请号为CN201620560125.4、名称为“一种塑料袋”的中国实用新型专利申请的优先权。
技术领域
本发明涉及物品承装袋技术领域，尤其涉及一种塑料袋。
背景技术
塑料袋是人们日常生活中必不可少的物品，常被用来装物品。因其廉价、重量极轻、容量大、便于收纳的优点被广泛使用。通常塑料袋包括多个塑料面，各个塑料面连接在一起后围成的空间，可以承装物品。塑料面之间的连接，目前大多采用热合的方式粘接在一起。而各塑料面经过热合粘接在一起后，形成的粘接边为一条直线。当塑料袋内承装物品后，物品对该粘接边所施加的力过于集中，导致该粘接边非常容易开裂。使塑料袋不能很好的承装物品，给人们生活、工作带来不便。
发明内容
本发明的目的在于提供一种塑料袋，该塑料袋封口端侧用于连接的粘接线可分散应力，使封口侧袋体的连接处不易损坏，从而提高了实用性。
为解决上述技术问题，本发明的技术方案是：
一种塑料袋包括：袋体，所述袋体的一端为封口端，其特征在于，所述封口端侧的所述袋体上设有粘接线；所述袋体的两侧侧壁分别伸入所述袋体的内部形成折叠区域，所述折叠区域与非折叠区域的交界区域的所述粘接线呈弧线，所述弧线的两端点位于所述折叠区域的内边缘的两侧。
优选方式为，所有所述弧线均向同一侧弯曲。
优选方式为，所有所述弧线均向所述封口端侧弯曲。
优选方式为，所有所述弧线均向远离所述封口端侧弯曲。
优选方式为，所述弧线为圆弧形。
采用上述技术方案后，本发明的有益效果是：因塑料袋折叠区域的封口端侧的粘接线呈弧线，使粘接线处被施力时，力度会被分散开来，不会造成因力量过于集中而使某处的粘接线断裂，塑料袋连接处裂开的情况发生。因此本发明的塑料袋，使用时底部不会轻易发生损坏，提高了实用性。
附图说明
图1是本发明塑料袋的结构示意图；
图2是实施例中的塑料袋的结构示意图；
图3是本发明塑料袋侧面撑开时的结构示意图；
图中：1—袋体、10—折叠区域、11—非折叠区域、2—封口端、3—提手、4—粘接线、5—弧线、6—挂孔。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明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发明，并不用于限定本发明。
如图1和图3所示，一种塑料袋包括袋体1，袋体1的一端为封口端2，封口端2侧的袋体1上设有粘接线4。袋体1的两侧侧壁分别伸入袋体1的内部形成折叠区域10，也就是袋体1的两侧为折叠区域10，中间为非折叠区域11。折叠区域10与非折叠区域11的交界区域的粘接线4呈弧线5，弧线5的两端点位于折叠区域10的内边缘的两侧。
所有弧线5均向同一侧弯曲，使应力分散更加均匀，进一步避免了断裂。图1中所有弧线5均向封口端2侧弯曲，弧线5优选圆弧形，还可以为其他弧形。
本实施例的塑料袋由塑料薄膜制成，袋体1还包括开口端，开口端侧袋体1的两侧设有提手3，中间设有挂孔6；每个提手3端部的袋体1连接在一起。
如图2所示，本发明的塑料袋所有弧线5均向远离封口端2的一侧弯曲。
本发明的塑料袋使用时，在未装物品时可通过挂孔6挂在某处，便于管理，同时塑料袋中间的两层塑料薄膜11上均设有一挂孔6，一个挂孔6用于固定， 一个挂孔6用于打开塑料袋，非常方便。当塑料袋打开后，两侧的折叠区域10被展开，使塑料袋围成空间去承装物品。再手提两侧的提手3时，在重力的作用下物品对封口端2侧的粘接线4施加压力，同时物品还对折叠区域10对应的粘接线4施加横向的拉力。因本发明的粘接线4包括弧线5，尤其是弧线5的两端部位于折叠区域10和非折叠区域11的交界区域的内边缘的两侧，将所承受的压力和拉力均匀的分散开来，避免了因应力过于集中而导致粘接线4裂开的情况发生。因此本发明的塑料袋，其非常耐用，不易损坏。
工业实用性
采用本发明所揭示的结构，使得塑料袋封口端侧的粘接线不易断裂，提高了实用性。
