改进结构的信封
摘要：
本发明涉及一种改进结构的带窗口的信封；它主要由：封面(1)、上下封底(22、21)、固定封舌(31)、活动封舌(32)、袋体(4)组成；其特征在于：封面(1)上开有窗口，袋体(4)的前面的四周粘着于封面(1)的背面上，并粘于窗口的边缘处；袋体(4)的开口(41)是朝向活动封舌(32)的；袋体(4)的前后两个面是相同大小或不同面积的且其材料为塑料，优选聚脂塑料；当然，袋体4的前后两个面中，远离窗口的一个面亦可为不透明的。本发明具有以下优点：1.对信封的生产厂商来说，可以采用统一规格的袋体，使生产更加标准、便捷化；2.对寄信人来说，收信人、寄件人信息的标签纸可不依信封规格而变化，采用相同的格式；3.可以节约纸张耗费和节省邮资。
摘要（英）：

The invention relates to an envelope with an improved structure and a window, which mainly comprises a cover (1), upper and lower back covers (22, 21), a fixed sealing flap (31), a movable sealing flap (32), and a bag body (4). The envelope is characterized in that the cover (1) is provided with the window, the periphery of the front part of the bag body (4) is struck on the rear side of the cover (1), and is struck on the edge of the window; an opening (41) of the bag body (4) faces toward the movable sealing flap (32); the front surface and the rear surface of the bag body (4) have the same size or difference areas and are made of plastic (the preferred material is polyester plastic); and of course, one, which is far away from the window, of the front surface and the rear surface of the bag body (4) can also be opaque. The envelope has the advantages that: 1, for manufactures of the envelope, the bag body with unified specification can be adopted to ensure that the production is more standard, convenient and quicker; 2, for senders, tagboards of information of addressees and the senders can be not changed according to the specification of the envelope, and adopt the same format; and 3, the envelope can save paper cost and save the postage.
