Description

一种模内标签 技术领域
本实用新型涉及标签技术领域，尤其涉及一种模内标签。
背景技术
模内贴标指在注塑、吹塑工艺加工塑料容器时，模内商标先由机械手贴附于模具内表面，在塑料容器吹胀成型或注塑成型时，利用原料本身热能商标内表面热融与容器外壁粘合，而外层印刷表面平稳，并能保持商标印刷的良好效果，在日化领域和调味品领域有了较多的应用。
但是现有的难以根据不同客人定制的需要，实现需要的多种效果，美观度不够，使得整体的档次较低，且在进行热熔贴合时，容易出现气泡、褶皱等现象，影响牢固度和平整度。
实用新型内容
本实用新型的目的是为了解决现有技术中存在的缺点，而提出的一种模内标签。
为了实现上述目的，本实用新型采用了如下技术方案：
一种模内标签，包括贴合层、透明保护层，所述贴合层的下端带有热熔胶，所述贴合层的上端设有图文层，所述透明保护层设置在图文层的上端，所述透明保护层靠近图文层的一侧表面设有转印层，所述贴合层的侧边设有环形凹槽，所述贴合层的下端中部设有凹陷口，所述贴合层的下端沿周向呈放射状设有与凹陷口连通的排气槽。
优选地，所述转印层通过转印形成，所述转印层设置在透明保护 层的边缘处。
优选地，所述图文层为印刷有油墨或镂空的薄膜。
优选地，所述排气槽的截面为等腰梯形结构，且排气槽的内底部宽度大于排气槽的开口宽度。
优选地，所述透明保护层的上端设有表面层。
优选地，所述贴合层、图文层、透明保护层、表面层相邻之间均通过粘黏剂粘合。
优选地，所述贴合层的下端中部设有凸部。
优选地，所述凸部由内向外设有两个环形的导流槽，所述导流槽与排气槽连通。
本实用新型的有益效果：
通过设置转印层，能给根据需要实现橘纹效果、金属效果、彩虹效果等多种效果，突显某些图文如商标等,或用来作为防伪标识；通过设置表面层，能给根据需要实现哑光效果、亮光效果、珠光效果，提升整体档次，满足不同客人定制的需要。
通过设置环形凹槽，在将贴合层与塑料吸附热成型时，塑料可在环形凹槽内成型，进而使得该模内贴标与塑料容器自然而然地触为一体，镶嵌牢固不易凸起或翘边，提升整体的牢固度和平整度，该模内贴标随瓶体的形状而改变，在塑料容器身上看不到标签的边角，外观看起来很漂亮。
通过设置凸部、排气槽、导流槽，在将贴合层与塑料吸附热成型时，贴合层的中心的凸部先与塑料容器接触，并通过吸附挤压的作用， 使得热熔胶通过导流槽流动至排气槽内，进而混合塑料填充排气槽并向外侧流动将气体排出，进而不会出现气泡、褶皱等现象，能够抗击生产和运输过程中的碰扭、刮擦和污染，使该模内贴标可长时间保持完整和美观。
本实用新型能够提升整体档次，满足不同客人定制的需要，并提升与塑料容器结合的牢固度和平整度，同时不会出现气泡、褶皱等现象，可长时间保持完整和美观。

具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型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实用新型一部分实施例，而不是全部的实施例。
在本实用新型的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。
实施例一
参照图1-3，一种模内标签，包括贴合层1、透明保护层5，透明保护层5为采用BOPP材质制成的透明薄膜，贴合层1的上端设有图文层4，图文层4为印刷有油墨或镂空的薄膜，薄膜表面通过油墨印刷形成图案、文字等图文信息,或是通过色彩薄膜镂空的形式形成图案、文字等图文信息，贴合层1采用OPP材质,贴合层1的下端带有热熔胶，可以与塑料材质在注塑或吸塑过程中能够与塑料紧密结合，透明保护层5设置在图文层4的上端，透明保护层5靠近图文层4的一侧表面设有转印层6，转印层6通过转印形成，转印层6设置在透明保护层5的边缘处，转印层6采用烫金热压的形式在透明保护 层5表面形成烫金的图案或文字，形成橘纹效果、金属效果、彩虹效果等多种效果，突显某些图文如商标等,同时在转印中结合凹凸压印技术，形成凸起的图案或文字，用来作为防伪标识，贴合层1、图文层4、透明保护层5相邻之间均通过粘黏剂3粘合，贴合层1的侧边设有环形凹槽2，贴合层1的下端中部设有凹陷口8，贴合层1的下端沿周向呈放射状设有与凹陷口8连通的排气槽7，热熔胶、塑料可填充排气槽7并向外侧流动将气体排出，进而不会出现气泡、褶皱等现象，同时排气槽7能够增大接触面积，使得贴合层1与塑料容器形成共融的区域更大，进一步提高连接的稳定性。
排气槽7的截面为等腰梯形结构，且排气槽7的内底部宽度大于排气槽7的开口宽度，使得塑料填充在排气槽7内时，能给有效实现卡合不易滑脱，进一步提高贴合层1与塑料容器贴合的牢固度。
实施例二
参照图4，本实施例与实施例一相比不同之处在于，本实施例透明保护层5的上端设有表面层9，透明保护层5、表面层9相邻之间均通过粘黏剂3粘合，表面层9可为哑光膜、珠光膜、亮光膜，能给根据需要实现哑光效果、亮光效果、珠光效果。
实施例三
参照图5、6，本实施例与实施例二相比更优之处在于，本实施例贴合层1的下端中部设有凸部10，在将贴合层1与塑料吸附热成型时，贴合层1的中心的凸部10先与塑料容器接触，并通过吸附挤压的作用，使得热熔胶、塑料向外侧流动，进而不易出现气泡、褶皱。
实施例四
参照图7，本实施例与实施例三相比更优之处在于，本实施例凸部10由内向外设有两个环形的导流槽11，导流槽11与排气槽7连通，使得热熔胶通过导流槽11流动至排气槽7内，进而混合塑料共融填充排气槽7并向外侧流动将气体排出。
以上，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。
