Abstract

本发明涉及密封可靠且易拆开的人字形顶纸盒。该纸盒包括一个人字形封闭，该密封又包括相对着的侧板和由此侧板延伸上去的侧折边。同时还有相对着的端板及由该端板延伸上去的端折边，端折边高度低于侧板边，侧板与端板上的刻线是为纸盒开启方便而设的，相对着的侧折边相互粘贴，而端折边粘贴到侧折边的下部部位上。其特征是留下了一个未被密封区域，此区域在端折边的上部中心部分，这就能有利消费者开启纸盒。

Description

本发明涉及人字形顶纸盒的改良结构。
人字形顶纸盒广泛用于象牛奶、果汁、泞檬汁产品以及蔬菜混合汁这类液体食品产品的包装中。当食品被冷藏时，象一盒牛奶，完善的密封并不是决定性的，而避免泄漏是希望达到的。由于牛奶的短期放置与冷藏，将不会有由于污染物进入纸盒而使其腐坏变质的实际问题。提供一种既密闭可靠又使消费者不很费劲即可打开包装的密封是做得到的。
象橘子汁或蔬菜汁这类产品的包装是另一种类型的包装，它们要有足够的放置期且不需要冷藏。如果密封不足，细菌、霉菌和酵母菌都可以污染产物并导致其腐坏变质。再者，如果空气进入容器内，可导致氧化。所以提供一个极度牢靠的密封是非常必要的。按照目前的经验，整体的顶盖是用热封的，印压有竖直桩线、水平桩线和中心桩点。结果，从普通消费者的观点来说，纸盒容器不易被打开。这样就使得人字形顶容器的主要用途变得无效了。人们使用各种各样的应急方法努力去解决这个问题，其中包括减弱拆开线的牢固程度，但是这种方法结果证明不是令人完全满意的。
因此，由上所述，本发明的目的就是提供一种具有牢固密封且易被拆开的人字形顶纸盒。
人字形顶纸盒的发明在符合上述要求方面获得了成功，这个人字形密封包括相对着的侧板和由该侧板延伸上去的侧折边，同时还有相对着的端板和由端板延伸上去的端折边，该端折边低于所说侧板的侧折边的高度，所说的侧板与端板上所具有的刻线是为了便于纸盒封闭和开启的，相对着的侧折边互相粘贴，并且，端折边粘贴到侧折边的下部的部位上，其特征就是留下了一个非密封的区域，此区域在端折边上部中心处，这样就有利于消费者开启纸盒。
在图中图示出本发明的最佳实施例。
图1是本发明的人字形顶容器的透视图。
图2是打开的图1中所示纸盒的透视图。是具有纸盒拆毁部分的。
图3是图1纸盒的展开图示，并呈现出已经被热封的地方。
图4是模具的正视图。该模具用于热封图1至图3所示的纸盒。
图5是本发明中的人字形纸盒的另一个开启的纸盒的实施例透视图。
图6是模具凸出部分的正面侧向透视图。该模具是用于生产图5所示实施例的。
图7是模具凹进部分的正面侧向透视图。该模具是用于生产图5所示实施例的。
现在参见附图，图示的纸盒是主要的传统结构。它包括相对着的侧壁对10和11，由第五板块12联系着（见图3）。有底部的封闭13和指示在14处的普通的人字形顶。人字形顶包括有一对侧板15，侧板上有刻痕线16以便于容易地开启纸盒;还包括有带有刻痕线18的端板17。一对顶部的侧边19是侧板15的延伸，并且它比端板17延伸的折边20高一些。如图1所示，折边19面对面被热封，折边20被热封到折边19下部的内部上，如图2所示，在端头通常提供一对桩线21，此桩线不被打开并和第五板块相合在一起。在另一端有固定线21a，还有水平桩线22，桩线是牢固地呈凹凸锯齿状以使密封更结实，还有桩点23，该桩点23是延伸到接界并封接在内部折叠的端折边的相邻的边缘并将其压在一起。这就是现有的传统结构。
根据本发明，与传统结构的不同之点在于折边19和折边20之间的密封区域的不同，在热充装时，根据传统的实践，是将整个折边20的内部封接到折边19上。按照本发明，一个呈倒三角形的理想区域被留下来没有封密，这个区域是在折边20的顶中间，由图2中的被拆开部位以数码25指示，余留的封密区域是画有横断阴影的，并被指示于24。在图3中非密封区域被指示于23a和23b，当纸盒封合时，23a和23b的结合就提供了区域23，这样就已详细地说明了，当在三角形的尖顶25处有个桩点23的位置时，即未密封区呈倒三角形状，在三角形顶点处有一桩点，不管这是个未密封区域，一种有效的密封被提供了，并且纸盒还有一水平桩线，该水平桩线在侧折边中，沿着端折边的顶。在顶端中间的非密封区域能使消费者开始开启纸盒。由于较小的密封而被拉开，消费者可利用杠杆作用毫不费力地开启纸盒。
如图所示的，是一个合适的压模30的凸形颚板，它包括模具正表面部分31，31用于把折边19的上部分压在一起，模具面上32和33部分可压制端头，还有水平凸起桩线34，竖直凸起桩线35，以及用于桩点36的隆起凸出部36，联接折边19和20的模具面37在38处被割去，以便留下了一个三角形的非密封区域，这个凸形模具可以和相应的凹形模具配合使用。
为提供所要求的非密封区域有两种选择，一种可以是包含有硅氧烷材料的使用，硅氧烷可作为隔离剂以防止区域25处粘着，另一种选择是如果以用粘着代替热封的话，可省去粘着区域25。然而，以热塑料树脂覆盖的纸盒，热密封是一种可推荐的封合方法。推荐的结构材料共有五层，名曰：一个聚乙烯内层，该内层用以接合簿箔，一个纸板层和一个聚乙烯外层，再一个是热塑料层，该层的热塑料类型是能适用食品的，诸如乙烯基树脂，即聚氯乙烯。但是纸盒内部至少要覆盖一层热塑料。
附图5示出一种改良的结构，这种结构是与图1到图4所示的结构相似的。但是有个非封闭或轻度封闭区域，该区域接近桩点23上方的折边20的顶部，实际上是以一个矩形25a代替图2中的三角形，并显示另一个非密封或是轻度密封的区域25b，该区域25b延伸于桩点23和桩线21a之间。区域25a和25b是留下的没有密封或轻度密封的，这是由于提供了一种模具，该模具在这些区域不施加压力或者施加较小的压力。也即，在具有一个非密封区域或轻度密封区域的端折边中，还有另一个未密封区域或轻度密封区域，该未密封区域或轻度密封区域是沿着端折边的下部实质上从中央延伸到与外边缘有一间距的点。水平桩线是在侧折边上的，并沿着端折边的顶。竖直桩线在侧折边的每个端头附近。所述另一未密封区或轻度密封区实质上就是从所说的桩点延伸到所说的端折边的桩线，桩点是在该区域之下的。
合适的压模的结构图示于图6和图7中，分别表示凸模颚板40和凹模颚板 41。现在来参阅图6凸模颚板40，它具有一个压模表面42，该表面具有高起的长凸条43以提供水平桩线，并有竖直凸条44和45以提供容器边上的桩线，这是为留着密封时用的，竖直凸条46以提供容器边上的一桩线，这是为打开时用的。凸模颚板40具有固定螺钉47以提供中央桩点23，图5中被松放的大致为矩形的区域25a是由接近固定螺钉47上方的非压区48提供的，纸盒边的方向上的凸起是被开启用的。还提供一个从固定螺钉47延展到直壁46的松放区域49，该固定螺钉47是提供桩点23的，而该直壁46是提供桩线21a的，桩点是紧邻非密封区之下处。凸模颚板40还包含有用于封闭容器的顶折边19的区域50以及区域51，52，53和54，它们是用于密封折边20的剩余部分的。
显示在图7中的凹模41，具有一个上部区域55，该上部区域55与凸模颚板上的部分50紧密配合，一个轻度凹进区域51的上边缘位于容纳凸条43处。模具41具有槽沟56和57以容纳直壁44和45，而槽沟58容纳直壁46，它还具有非压区59以松放压力并与凸模的区域49相匹配以及大致为矩形的压力松放区域60，该区域与凹模区域48匹配。
