Description

一种纸杯盖及其制备方法 技术领域
本发明涉及杯盖技术领域，具体涉及一种纸杯盖及其制备方法。
背景技术
目前有一种纸杯盖，包括中空的纸盖体和圆形的纸盖板，纸盖体的位于底端的圆形边缘从下往上向内弧形卷起形成弧形卷，纸盖板粘接有一薄纸张，该薄纸张绕住粘接在所述弧形卷上。
该纸杯盖需要用薄纸张作为中间的连接部件来连接纸盖体和纸盖板，而且需要使用胶水来固定。胶水是化学物，容易对饮品产生不良影响；而且每一个纸杯盖都要使用一薄纸张，薄纸张的用量也很大。
需要说明的是，本发明从此上述的纸杯盖出发进行创新。但是该公开于该背景技术的信息仅仅旨在增加对本发明的总体背景的理解，而不应当被视为承认或以任何形式暗示该信息构成已成为本领域技术人员所公知的现有技术。
发明内容
有鉴于此，为解决上述技术问题，本发明的目的在于提出一种节省纸张，不用胶水的纸杯盖及其制备方法。
所采用的技术方案为：
本发明的一种纸杯盖，包括中空的纸盖体和圆形的纸盖板，所述纸盖体的位于底端的圆形边缘从下往上向内弧形卷起形成弧形卷，将弧形卷的上端压平，形成一平面环状的连接面，所述连接面与纸盖板的平面边缘压合固定。
进一步地，将弧形卷的下端压平，形成另一平面环状的连接面。
进一步地，所述纸盖板为单层。
进一步地，所述纸盖板设有饮用口，所述饮用口的形状大小均与一盖片相匹配，所述盖片的一侧与纸盖板一体连接；所述盖片的另一侧可扣合在弧形卷 的侧端，也可从弧形卷侧端的扣合处掀起。
进一步地，在所述盖片的外周设有封闭的凸缘，使所述盖片位于所述凸缘之内。
进一步地，所述纸盖体的位于顶端的圆形边缘从上往下向外弧形卷起形成另一弧形卷。
本发明的上述纸杯盖的制备方法，包括如下步骤：
S1.将纸盖体的位于底端的圆形边缘从下往上向内弧形卷起形成弧形卷；
S2.将弧形卷的上端压平，形成一平面环状的连接面；
S3.将连接面与纸盖板的平面边缘压合固定。
进一步地，S2中，用模具将位于上端的弧形卷压平。
本发明的有益效果在于：
通过压平形成一平面环状的连接面，连接面与纸盖板的平面边缘压合固定，从而不仅能够起到密封性和牢固性作用，而且能大大节省纸张，不用胶水，非常环保。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为实施例1的纸杯盖分解的剖视结构示意图。
图2为图1的纸杯盖结合后的剖视结构示意图。
图3为图2的纸杯盖扣合盖片时的仰视结构示意图。
图4为图2的纸杯盖掀起盖片时的仰视结构示意图。
图5为实施例2的纸杯盖分解的剖视结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明优选的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例1
参见图1至图4所示，一种纸杯盖，包括中空的纸盖体1和圆形的纸盖板2，纸盖体1的顶端和底端均为圆形，纸盖体2整体上呈或大致呈圆台型，位于底端的圆形边缘从下往上向内弧形卷起形成弧形卷，将弧形卷的上端压平，形成一平面环状的连接面3，连接面3与纸盖板2的平面边缘压合固定。位于顶端的圆形边缘也可以从上往下向外弧形卷起形成另一个弧形卷。
本实施例的纸盖板2可以只为单层。
本实施例的纸盖板2设有饮用口3，所述饮用口3的形状大小均与一盖片4相匹配，盖片4的一侧与纸盖板2一体连接；盖片4的另一侧可扣合在弧形卷的侧端5，也可从弧形卷侧端5的扣合处掀起。纸质的盖片具有弹性作用，这是利用盖片自身的弹性作用，从而可以直接扣合在位于侧端的弧形卷，然后又可以直接从位于侧端的弧形卷扣合处掀起。这样就省去了另外设置一个用于盖片上的卡扣结构，巧妙地利用了弧形卷侧端的弧形结构作为卡扣结构。
作为一种优选的实施方式，本实施例在盖片4的外周设有封闭的凸缘6，使盖片4位于凸缘6之内，这样，可以控制液体饮品的残余量，使液体饮品的残余量位于凸缘之内，并流回饮用口，不会流向别处。
上述纸杯盖的制备方法，包括如下步骤：
S1.将纸盖体的位于底端的圆形边缘从下往上向内弧形卷起形成弧形卷；
S2.将弧形卷的上端压平，形成一平面环状的连接面；
S3.将连接面与纸盖板的平面边缘压合固定。
S2中，可以用模具很好地将位于上端的弧形卷压平。S3中，压合固定可以为超声波压合，也可以为热压压合等物理性压合。由于是面与面之间的压合，超声波压合或热压压合等物理性压合，可以很牢固地将连接面与纸盖板的平面边缘压合固定。
从而通过将弧形卷的上端压平，形成一平面环状的连接面，将连接面与纸盖板的平面边缘压合固定，使得纸杯盖不仅具有密封性和牢固性，而且能大大节省纸张，不用胶水，非常环保。
实施例2
参照实施例1，在实施例1的基础上，将位于下端的弧形卷压平，形成另一平面环状的连接面7。上下两面压平更方便模具的加工。
实施例3
作为一种优选的实施例，纸盖体的位于顶端的圆形边缘从上往下向外弧形卷起形成另一弧形卷，从而形成一种优质纸杯盖。该另一弧形卷可以减少单层纸质材料的厚度来进行卷边，又能够增加强度1倍以上。
需要说明的是，在本发明的描述中，术语“顶端”、“底端”、“上端”、下端等指示的方位，是基于附图1-2所示的方位而进行的描述，仅是为了更方便的描述，而不是指示或暗示所指的部件或元件必须具有特定的方位，因此不能理解为对本发明的限制。当附图1-2的位置旋转180°时，其相应的方位术语也适应性发生变化，这应当不影响本发明的保护范围。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施例的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施例或变更均应包含在本发明的保护范围之内。
