摘要： A can lid comprises a metallic lid surface in which an opening is formed which is bounded by a closed margin of the lid surface and which is closed by a closure piece. The closure piece is separated from the surrounding lid surface by a microgap extending at least sectionally along the margin of the lid surface. A margin of the closure piece and the margin of the surrounding lid surface adjoin one another at the microgap. The closure piece can be moved out of the plane defined by the opening to release the opening. The can lid further comprises a layer composed of a plastic material applied to a flat side of the metallic lid surface in a manner covering the microgap. The margin of the closure piece and the margin of the surrounding lid surface are offset from one another transversely to the plane defined by the opening.

摘要： An easy-opening closure for hermetic sealing of the open end of a packaging container includes an end member for being double-seamed to the open end of the container and having an interior ledge portion defining a large central opening and a composite lidding member of at least two polymer layers defining a predetermined peel strength at an interfacial plane for controlled delamination of the two layers. The composite lidding member covers the central opening and is bonded to the ledge portion to define a bond strength greater than the peel strength of the two polymer layers. The lidding member has a continuous ring-shaped notch cut into the bottom polymer layer adjacent the ledge portion and a discontinuous ring-shaped notch cut into the top polymer layer and spaced inwardly from the first notch to define a small unnotched portion between its ends and to define with the first notch a ring member therebetween which is connected at the unnotched portion to the central portion of the lidding member. With this construction, the force required to open the closure from the inside of the container is greater than the force required to open the closure from the outside of the container. The closure is circumferentially opened by upward pulling of the bonded overlapping portion of the composite lidding member to cause delamination and peeling of the top polymer layer from the bottom polymer layer bonded to the end member in an area between the first notch and an outside circumference of the lidding member and removal of the ring member between the first and second notches.

摘要： A structure is provided in a container having a fluent material, such as a liquid or powder, to be selectively dispensed therefrom, and a simple, quick opening means for the container which may be effected without the need for special tooling such as a can opener.In one form, an opening is provided in the wall of a metal, plastic or paperboard container through which the contents thereof may be dispensed. Simple closure means is provided in the form of a short plastic or metal strip which is sealed to the container around the opening to close off same. The strip contains an unsealed tab portion at one end thereof which normally lies flat against the container wall and may be easily lifted by hand and pulled to break the seal with the wall of the container and to expose the opening.

摘要： An easy-opening closure for hermetic sealing of the open end of a packaging container (100) includes an end member (20) for being double-seamed to the open end of the container and having an interior ledge portion (23) defining a large central opening (24) and a composite lidding member (30) of at least two polymer layers (35, 36) defining a predetermined peel strength at an interfacial plane for controlled delamination of the two layers. The composite lidding member covers the central opening and is bonded to the ledge portion to define a bond strength greater than the peel strength of the two polymer layers. The lidding member has a continuous ring-shaped notch (67) cut into the bottom polymer layer adjacent the ledge portion and a discontinuous ring-shaped notch (69) cut into the top polymer layer and spaced inwardly from the first notch to define a small unnotched portion between its ends and to define with the first notch a ring member therebetween which is connected at the unnotched portion to the central portion of the lidding member. With this construction, the force required to open the closure from the inside of the container is greater than the force required to open the closure from the outside of the container.

摘要： An easy-opening closure is provided for hermetic sealing of the open end of a packaging container. The closure includes a composite end for being double-seamed to the container and having an interior ledge portion defining a central opening through the closure. The composite end includes at least two polymer layers defining a predetermined peel strength for delamination and a formable substrate layer bonded to the bottom one of the polymer layers and adapting the end member to be double-seamed to the container. The end member has a notch cut into the top polymer layer in the ledge portion which is spaced from and surrounds the central opening. A lidding member covers the central opening and has a portion overlapping and bonded to the top polymer layer in the ledge portion of the end member to define a predetermined bond strength greater than the peel strength of the two polymer layers of the end member. With this construction, the force required to open the closure from the inside of the container is greater than the force required to open the closure from the outside of the container since the closure is easily-opened by upward pulling of the bonded overlapping portions of the lidding member to cause delamination and peeling of the portion of the top polymer layer bonded to the lidding member from the bottom polymer layer beginning at the notch and continuing to the central opening.
摘要翻译：提供了一种容易打开的封闭件，用于密封封装容器的开口端。封闭件包括复合端部，用于双重接合到容器并且具有限定通过封闭件的中心开口的内部凸缘部分。复合端包括限定用于分层的预定剥离强度的至少两个聚合物层和结合到聚合物层的底部一个的可成形基材层，并且使端部构件双重缝合到容器。端部构件具有切割成突出部分中的顶部聚合物层的切口，其与中心开口间隔开并且围绕中心开口。封盖构件覆盖中心开口并且具有与端部构件的凸缘部分中的顶部聚合物层重叠并结合的部分，以限定比端部构件的两个聚合物层的剥离强度大的预定粘结强度。利用这种结构，从容器内部打开封闭件所需的力大于从容器的外部打开封闭件所需的力，因为封闭件通过向上拉动粘合的重叠部分容易地打开封闭构件使从底部聚合物层开始从凹口开始并连续到中心开口的结合到封盖构件的顶部聚合物层的部分脱层和剥离。

摘要： A molded plastic container having a weakened portion of its wall which may be severed by a pushing or pulling action using one or more fingers of the hand to allow dispensing the contents of the container through the resultant opening. In one form the weakened portion is defined by a channel in the wall defining an open loop of reduced wall thickness. Severance may be effected of the material inwardly of the open loop by pressing inwardly with the finger of the hand. In another form, the loop defined by the channel in the wall is closed and is irregularly shaped to permit it to be manipulated or grasped by the finger to assist in severing the tab and/or to permit the tab to be pulled out once it is partly severed. The method for forming the channel is also provided.

摘要： PURPOSE: A drink can having a cover tip is provided to promote sanitary use of a drink can and easiness in management and treatment by adopting a cover tip for closing an opened drink hole portion selectively. CONSTITUTION: A cover tip(2) is set on a rotatable shaft portion(15) of an opener tip(13) in an upper cover(12). The cover tip has a side fixed to the rotatable shaft portion but slightly larger than the opener tip of a drink hole. The other side of the cover tip having a fan shape is positioned under the opener tip in a perpendicular direction. The drink hole is opened when a user removes a hole tip(14) of the drink hole by using the opener tip. If the user leaves a specific amount of liquid drink in a drink can(1), the user closes the drink hole with the cover tip. Thereby, the liquid drink in the can is kept regular without losing carbonic acid if the liquid drink in the can is a kind of carbonic acid drink. In addition, the liquid drink does not overflow when a shock is applied to the drink can having the drink hole opened.
摘要翻译：目的：提供具有盖尖的饮料，以通过采用用于选择性地关闭打开的饮料孔部分的盖尖来促进饮料罐的卫生使用和管理和处理的容易性。构成：盖顶部（2）设置在上盖（12）中的开启端（13）的可旋转轴部分（15）上。盖顶部具有固定到可旋转轴部分但稍大于饮料孔的开启尖端的一侧。具有扇形的盖尖的另一侧在垂直方向上位于开启顶端的下方。当用户通过使用开启尖端去除饮料孔的孔尖（14）时，打开饮料孔。如果用户在饮料罐（1）中留下特定量的液体饮料，则用户用盖尖关闭饮料孔。因此，如果罐中的液体饮料是一种碳酸饮料，罐中的液体饮料将保持规则而不会损失碳酸。此外，当饮料孔打开的饮料罐受到冲击时，液体饮料不会溢出。
