アや切込みを全く有しない簡易開口容器に関する
ものである。[Detailed description of the invention] The invention is an easy-to-open container sealed with a lid made of a composite sheet containing metal foil such as aluminum foil, or a single-layer sheet. This relates to an easy-to-open container that does not need to be opened.
粉ミルクなどの缶の蓋には、0.2〜0.35mm程度

深さを有するスコアを設け、蓋の一部に中空状の
リベツトを形成せしめ、このリベツトに開缶用タ

上記スコア線を破断除去する形式のものが用いら
れている。 For the lids of cans of powdered milk, etc., a score having a depth of approximately 0.11 to 0.18 mm is provided on an aluminum material having a thickness of approximately 0.2 to 0.35 mm, and a hollow rivet is formed in a part of the lid. A can-opening tab is caulked to the rivet, and the score line is broken and removed by the lever action of the tab.
このような形式のものは、開裂後の蓋が鋭利な
端縁を有しているので、その処置に困ることがあ

に対し、均一で精度のよいスコア形成を行うため
には、高精度のプレス機械が必要であり、更に精
度向上のため肉厚のアルミ材を使用せざるを得な
いこととが相俟つて、コストアツプにつながると
いう欠点があつた。 This type of lid has sharp edges after being torn, so it may be difficult to handle it. Furthermore, when such a lid is subjected to vibrations or shocks during transportation, stress may concentrate on the score area, causing it to open unexpectedly.
Since it often occurs on large-diameter lids, extreme care was required when handling it. Furthermore, in order to form uniform and accurate scores on thin aluminum materials, a high-precision press machine is required, and thick aluminum materials must be used to further improve accuracy. This combined with the drawback of increasing costs.

案内として切断するカツターを別個に組合わせる
か、あるいは、消費者が適当な刃物などの開口具
を使用して開口しなければならず、開口操作が煩
雑であるという欠点があつた。 Another type of lid is one made of metal foil, a synthetic resin sheet, or a composite sheet of these, which is formed to fit over the opening of the container, and then wrapped or fused with a metal or plastic ring. ,
This type of product requires a separate combination of cutters that use the container's opening edge as a guide to cut the container, or the consumer must use an appropriate knife or other opening tool to open the container. The disadvantage was that the operation was complicated.
このような金属箔を基材とした蓋に対し、きわ

が、たかだか0.1mm程度の薄い金属箔を基材とし
たシートに、きわめて浅いスコアを付すことは高
精度のプレス機械をもつてしても困難なことであ
り、実用性に乏しい。 All of the above-mentioned drawbacks can be overcome by forming an extremely shallow score on a lid made of metal foil and fusing a tension piece for the opening, but the thin score of about 0.1 mm at most can be eliminated. It is difficult to give extremely shallow scores to a sheet made of metal foil as a base material, even with a high-precision press machine, and it is impractical.
このような問題点を解消するために、本件出願

やすくなるため中断する。 In order to solve these problems, the applicants of the present invention provided an easy-to-open container as shown in FIG. 1 as Utility Model Application No. 177932/1983. The opening of the lid shown in FIG. 1 is such that when the grip 1 is pulled up after the initial tearing, the lid 2 is torn along the guide edge 3 to the opening edge 5 of the ring 4 made of metal or plastic; A tear occurs on the inner guide edge 6 starting from point a. If the grip part 1 is still pulled up, the tear that reached the opening edge 5 will progress along this opening edge 5, and the tear that was along the inner guide edge 6 will progress to approximately half the circumference, and the tear that has reached the opening edge 5 will progress to the center of the lid. If sagging occurs in the tearing direction, the lid 2 tends to sag depending on the direction of tearing, so the process is interrupted.
従つて、開口縁５にそつた部分にのみ、引裂き
応力が集中され、外側引裂きのみが最後まで持続
されて完全開口がなしうるものである。 Therefore, the tearing stress is concentrated only on the portion along the opening edge 5, and only the outer tearing is sustained until the end, so that a complete opening can be achieved.

In some cases, tearing using the inner guide edge 6 as a guide is interrupted because it lacks smoothness or progresses to half the circumference. The stress of rough tearing is dispersed, and the opening edge 5
In some cases, the opening tension piece 7 was torn in the middle, and as shown by the imaginary line, an uncut portion of the lid 2 was left at the opening edge 5 at about 180° from the initial opening.

By this means, the entire lid is tension-free and the stress caused by the tearing of the outermost opening tension piece is concentrated on the opening edge of the ring, thereby providing an opening container that can be reliably opened without any uncut edges. . It is also an object of the present invention to provide a container in which the contents can be taken out or the container can be slit while the outermost opening tension piece remains torn.

FIG. 5 is an example of use in a secondary opening state, and
An innermost opening tension piece 26 having a similar shape is further disposed inside the inner opening tension piece 15, and this is fused or adhered to the upper surface of the lid 11 under the same conditions as the others. put. Even if the primary opening is performed by this innermost opening tension piece 26 and there is an uncut portion on the inner guide edge 25 facing the straight part 15d of the inner opening tension piece 15, the secondary opening by the inner opening tension piece 15 is performed. , without tearing stress being distributed.
This stress causes the inner guide edge 22 of the outer opening tension piece 16 to
Therefore, tearing of the inner opening tension piece 15 is performed extremely smoothly, and tearing of the outer opening tension piece 16 is performed extremely smoothly.
There are no uncut edges on the inner guide edge 22 of the
Therefore, a container in which slitting can be performed accurately is obtained. If this slitting is not the purpose, it is of course possible to tear the inner opening tension piece 15 followed by tearing with the outer opening tension piece 16 to completely open the opening.

例のものに特定されることはない。 In the embodiments shown in FIGS. 2 to 5 above,
The direction in which the grips attached to the inner and outer opening tension pieces 15, 16 and the innermost opening tension piece 26 are pulled up is
Each direction is alternately opposite. The reason for this is, for example,
To explain the embodiment of FIG. 2, the tear along the inner guide edge 22 of the outer opening tension piece 16 hits the primary opening by the inner opening tension piece 15, and the tear along the inner guide edge 22 of the outer opening tension piece 16 is caused by the guide provided at the terminal end 16c of the outer opening tension piece 16. Rim 24
The direction of tearing is reversed to prevent interference. However, as shown in FIG. 6, by making the starting end of the guide edge 24 provided at the terminal end of the outer opening tension piece 16 substantially perpendicular to the inner guide edge 22, tearing along the inner guide edge 22 can be avoided. However, since the guide edge 24 can be prevented from interfering with the guide edge 24, the gripping portions of the inner and outer opening tension pieces can be pulled up in the same direction. Therefore, the pulling direction of the gripping portion of each opening tension piece is arbitrary and is not limited to the one in the embodiment.

しうるなど、実用上の効果は大きい。 As described above, according to the present invention, a large opening is formed in the lid by tearing the opening of the innermost opening tension piece, and this primary opening eliminates the tension on the entire lid, and the opening tension piece of the outermost opening The stress caused by the tearing of the ring is concentrated on the opening edge of the ring, ensuring an opening with no uncut parts. In addition, by providing a plurality of opening tension pieces concentrically in this way, the contents can be taken out in the state of the primary opening, and by forming at least a straight part on the outer opening tension piece, the contents can be removed. It has great practical effects, such as being able to pick things up and take them out.
