Description

自助式干燥食品保鲜包装袋结构
技术领域
本发明涉及一种自助式干燥食品保鲜包装袋结构，当操作者食用干燥食品后并开始保鲜干燥食品时，仅需拉持包装袋外部的拉掣部以将保鲜器的封口薄膜撕开，进而包装袋内部的干燥食品通过保鲜剂保持干燥，增进使用便利性及食品保鲜性。
背景技术
干燥食品，如茶叶、咖啡、饼干或零食等食品采用包装袋包装，常见在包装袋内的食品一并投入保鲜剂，如干燥剂/脱氧剂等一起包装，如此减少、降低或避免食品受潮、氧化或变质；一般而言，干燥剂/脱氧剂，是以透气纸装成小包的形式投放到食品包装袋中，若食品包装袋外部受到不当外力挤压，会因干燥剂包/脱氧剂包存在有破损或破裂的可能，而难以完全避免食品不受污染，甚至因一时疏忽或因孩童不懂的辨识而发生误食事件，长期影响到食品包鲜包装的安全性。
发明内容
有鉴于此，现有的食品保鲜包装袋尚有进步空间，其安全性及方便性仍需改善，故本发明人乃针其所面临的问题深入探讨，并凭借多年从事相关产业的开发经验，而积极寻求解决之道，经不断努力的研究与长期测试，终于成功的发明出一种自助式干燥食品保鲜包装袋结构，以克服前述现有食品保鲜包装袋无法解决的问题。
为实现上述目的，本发明采用的技术方案是：
一种自助式干燥食品保鲜包装袋结构，其特征在于：包装袋内设有一保鲜器，该保鲜器包含有一耐挤压材料成型的收纳盒，该收纳盒的一面端贴合在该包装袋的内表面上，其内部具有一收纳室，该收纳室内填设有保鲜剂，且该收纳室的一面端形成有一出口，该出口上设有一透气薄膜以阻隔该保鲜剂外漏，又该透气薄膜的外部设置有一将该收纳室封闭的封口薄膜，该封口薄膜一端延伸至该包装袋的袋口外部而形成有一拉掣部。
所述的自助式干燥食品保鲜包装袋结构，其中，该透气薄膜及该封口薄膜由内而外贴设在该收纳室的该出口上，该出口位于该收纳盒贴合在该包装袋的相异端，当欲装干燥食品时，仅需打开该包装袋的袋口，通过该拉掣部的抓取，朝该包装袋的袋口外拉动撕开该封口薄膜，以脱离该收纳盒的该出口，并当投入食品后，将该包装袋的袋口封闭时，即能凭借该收纳室内部的该保鲜剂与该包装袋内部空间相通，产生保鲜效果。
所述的自助式干燥食品保鲜包装袋结构，其中，该出口至该收纳室之间，形成有一间隔层，该间隔层上设有至少一个使该出口与该收纳室相通的穿孔，且该透气薄膜贴设在该间隔层的一端表面上。
所述的自助式干燥食品保鲜包装袋结构，其中，该拉掣部开设有一夹片切口并由该夹片切口形成有一夹持片，该拉掣部凭借该夹持片夹持于该包装袋的袋口端，使该拉掣部维持在该包装袋的该袋口外部。
所述的自助式干燥食品保鲜包装袋结构，其中，该封口薄膜一端由一弯折180度的弯折部延伸至该包装袋的该袋口外形成该拉掣部，且该弯折部的弯折方向是由该封口薄膜的内边缘并朝该包装袋的该袋口反折。
所述的自助式干燥食品保鲜包装袋结构，其中，该透气薄膜及该封口薄膜由内而外贴设在该收纳室的该出口上一侧，该收纳盒在该出口贴合在该包装袋的一端形成有一贴膜框面，该封口薄膜具有两面，一面贴设在该贴膜框面上，而再由另一面表面与该包装袋的内表面贴合，且该封口薄膜与该拉掣部的连接处形成有至少一个切缝线；通过在该包装袋的该出口外部进行外拉持在该拉掣部，断开该切缝线，造成该封口薄膜上产生一缺口，使该收纳室内的该保鲜剂能由该缺口与该包装袋内部空间相通，造成食品在封口的该包装袋内产生保鲜效果。
所述的自助式干燥食品保鲜包装袋结构，其中，该拉掣部开设有一夹片切口并由该夹片切口形成有一夹持片，该拉掣部凭借该夹持片夹持于该包装袋的袋口端，使该拉掣部维持在该包装袋的该袋口外部。
所述的自助式干燥食品保鲜包装袋结构，其中，该包装袋为夹链袋。
所述的自助式干燥食品保鲜包装袋结构，其中，该包装袋为热封口机封合的热封袋。
本发明的主要优点是提供一种自助式干燥食品保鲜包装袋结构，该透气薄膜及该封口薄膜由内而外贴设在该收纳室的该出口上，该出口位于该收纳盒贴合在该包装袋的相异端，当欲装干燥食品时，仅需打开该包装袋的袋口，通过该拉掣部的抓取，朝该包装袋的袋口外拉动撕开该封口薄膜，以脱离该收纳盒的该出口，并当投入食品后，将该包装袋的袋口封闭时，即能凭借该收纳室内部的该保鲜剂与该包装袋内部空间相通，产生保鲜效果。
本发明的另一优点是提供一种自助式干燥食品保鲜包装袋结构，该透气薄膜及该封口薄膜由内而外贴设在该收纳室的该出口上一侧，该收纳盒系在该出口贴合在该包装袋的一端，形成有一贴膜框面，该封口薄膜具有两面，一面贴设在该贴膜框面上，而再由另一面表面与该包装袋的内表面贴合，且该封口薄膜与该拉掣部的连接处形成有至少一个切缝线；通过在该包装袋的该出口外部进行外拉持在该拉掣部，断开该切缝线，造成该封口薄膜上产生一缺口，使该收纳室内的该保鲜剂能由该缺口与该包装袋内部空间相通，造成食品在封口的该包装袋内产生保鲜效果。
如此创新独特设计，使本发明的该自助式干燥食品保鲜包装袋结构，系当操作者食用干燥食品后并开始保鲜干燥食品时，仅需拉持该拉掣部以将该保鲜器的该封口薄膜撕开，进而该包装袋内部的干燥食品通过该保鲜剂保持干燥，增进使用便利性及食品保鲜性。
