器に関する。[Detailed Description of the Invention] [Background of the Invention] [Industrial Field of Application] The present invention prevents powder and granules stored inside the can from being scattered into the atmosphere when compressed gas is released when the can is opened. This invention relates to an easy-to-open fully open can container that prevents scattering of powder and granular materials.

ルとして用いている。<Prior Art> Conventionally, easy-open type full-open collars, which are formed so that almost the entire end panel of the can can be removed, have a pull tab fixed to the removable panel portion of the end. First, it is used to cause the initial tearing of the end panel and then as a handle to tear off the removable panel portion.

環状の弱目線の一部に裂開を生しさせる。This removable panel section has a U-shaped line of weakness cut into it immediately adjacent to the connection between the pull tab and this section.
By tearing it open, the gas inside the container will be released into the atmosphere, and then this U-shaped weakened line will cause the torn part to form a thread, thereby further causing the pull tab. As the tab is pivoted relative to the end panel and lifted about the anchor point, the nose of the pull tab pushes into a portion of the lid of the end panel and ruptures a portion of the annular weak line. make it come alive.

き缶開させてフルオープン化容器を開けていた。Further, by pulling up this pull tab, the entire lid is torn along the weak line from the tearing part of the end panel, and the entire lid, which occupies most of the end panel, is removed and the can is opened, resulting in a fully open container. It was open.

器にっていは多くの提案がなされていない。In carbonated beverages such as beer, which are consumed by releasing compressed gas stored inside these easy-open cans into the atmosphere, when the lid is opened, the gas is released into the atmosphere, and a gas-liquid mixture ( In order to prevent this, a can lid with a fine mesh placed on the back side of the can lid to prevent the contents from scattering (Utility Model Publication No. 48-30259) (see Japanese Patent Application Laid-open No. 70686/1986), or a can lid with a metal fitting with a pinhole attached to the back side of the opening of the can lid (see Japanese Patent Application Laid-open No. 70686/1986). Various improvements have been made, such as a can lid with a thin resin film plate on the inside of the can (see Utility Model Application Publication No. 47-22065), but there are many proposals for fully open cans. Not done.
〈発明が解決しようとする課題〉
前記缶蓋の裏側に細網を張ったものは圧縮ガスの抜けが
良好で粉粒体が圧縮ガスの放出と共に飛散することは無
いが、開缶後に細網が残存して見栄えが悪いし、開缶に
二重の手間がかかるといった欠点がある。<Problems to be Solved by the Invention> The can lid with a fine mesh on the back side allows the compressed gas to escape well and the powder particles do not scatter with the release of the compressed gas, but the fine mesh does not form after the can is opened. The disadvantages are that the residue remains, which makes it look unsightly, and that opening the can requires double effort.

全にガスが抜かれない状態のまま開缶されるので、フル
オープン化のような開口部の広い蓋では、粉粒体の飛散
を避けることができ難いとの問題点があった。In addition, if the metal fitting with the pinhole is attached to the back side of the opening of the can lid, the release of compressed gas may be slow, or the can may be opened without the gas being completely released, so it may be difficult to fully open the can. A lid with a wide opening has a problem in that it is difficult to prevent powder from scattering.

スと共に飛散するといった問題点があった。Particularly in the case of a person who opens a can by rapidly raising the pull tab to cause a split in the U-shaped weak line and a tear in the annular weak line at almost the same time. When gas is still not released from the initially cleaved part, f1. There was a problem that the powder particles were scattered together with the compressed gas.

た。Furthermore, in cases where a synthetic resin thin film plate that is expanded to the width of the end panel is provided on the back of the can lid, when the can is opened, the thin film plate is pushed upward by the pressure of the compressed gas, preventing the release of the compressed gas. This can prevent the powder and granules from scattering, but this slows down the escape of the compressed gas, and if the pull tab is pulled up rapidly, the powder and granules described above will be released together with the compressed gas. There were problems such as scattering.

基づき本発明を完成するに至った。Summary> As a result of extensive research in view of the above issues, the inventors of the present invention have developed a U-shaped weak line part and a tab on the inside of the end panel, which is the first tearing part of a fully open can container lid. The weak l] line part torn by the nose part of the can is covered with a stretchable film provided with pores, and at least a part of the film is tightly wrapped around the seam part of the fully open can container. At the same time, by fixing a part of the film to the lid and making a cut line along the weak line of the full-open can container lid in a region other than the part where the nose of the tab is pushed, the lid of the full-open can container can be fixed. The tensile tab fixed to the film is pulled up to create a crack in the U-shaped weak line formed near the fixation point of the tab, releasing the compressed gas into the atmosphere through the pores of the film, and further tightening the tab. Even if a part of the lid of the end panel is pushed in by the nose part and a part of the annular weak line is ruptured, the compressed gas inside the can can be released through the pores of the film and the can can be stored inside the can. The present invention was completed based on the knowledge that it is possible to separate the compressed gas from the granular material that has been used.

形成されていること、を特徴とするものである。That is, in the easy-to-open fully open can container of the present invention that prevents scattering of powder and granular material, an annular weak line is carved along the periphery of the end panel that forms the lid of the can container, and the weak line is This is an easy-to-open can container for powder, in which a pull tab is fixed to the end panel on the inner side of the weak line so that the nose part of the pull tab touches, and a U-shaped weak line is formed near the fixing point of the tab. In order to open the lid, when the pull tab is pulled up using the fixing point as a fulcrum, a crack is generated in the U-shaped weak line formed near the fixing point, and the can container is in an unsealed state. (hereinafter referred to as "first unsealing"), and then this pull tab is further raised using the fixed point as a fulcrum, and the nose part of the tab pushes a part of the lid part of the end panel and splits it into a part of the annular weak line. By causing an opening and pulling this pull tab, the entire lid part is torn along the weak line from the tearing part of the end panel and removed (hereinafter referred to as "second opening") to prevent scattering of powder and granular material. In the easy-to-open full-open can container, the weak line is engraved with a film that is at least partially wrapped and fixed to the wrapping portion of the full-open can container, and a portion of the film is fixed to the lid portion. The U-shaped weak line part, which is the first part of the lid of the fully open can container formed by the process, and the part of the weak line that is pushed by the nose part of the pull tab and the part of the weak line is torn are separated from the inside of the can. The film has a cut line along the weak line of the annular shape except around the area where the lid part is pushed by the nose part of the pull tab, and the film has a cut line along the weak line of the annular shape except for the area where the lid part is pushed in by the nose part of the pull tab, and the film has a cut line along the weak line of the annular shape, and the film is cut at the initial tearing part of the can lid. A pore is provided near the weak line of the U-shape, and the film is made of a material with such extensibility that it will not be damaged when the nose of the pull tab is pushed into it. It is characterized by:
