Nosan is attached. However, this lid must be fitted with a tear tab in the opening in advance, which increases the number of manufacturing processes. In addition, the opening remains sharp at the tearing part of the container. Defects such as causing various kinds of pollution when separated from water are actually pointed out. In order to solve this problem, a push-to-split type simple open container has been developed. According to the inventor of the present invention, “a single thin plate is formed with a convex portion having a deep drawing process!), And is cut to a part or the entire periphery near the periphery of the convex portion.

前記の蓋は凸部を押込むことによ ]?切断案内線を裂開し開口す るものであるが、 この切断案内線は一挙に裂開するのでは く、 最も剪断負荷がかかる局部から裂開し始め、 その後他へ誘導され て裂開が進行する過程をもって裂開される性質のものである。 従 つて、 凸部への押圧力の最大値は常に当初の押込開始時に記録さ れ、 それによつて局部が裂開した後は極めて低い押圧力で裂開進 行する。 かかる性質は前記蓋の発明時に既に明らかに ¾つている ものであ 、 凸部の平面形状を長円と し、 同 部の一端から他端 へ順次押込むことによつて長円の開口部分を得る簡易開口容器盞 と して具体的に案出されているカ 本発明は切断案内線の前記性 質を利用しつつ、 更に低押圧力で押込開口が可能であ ]?、 又種々 の大きさの開口部を自由に得ることが可能な簡易開口容器蓋を提 供することを目的とする。 - 以下本発明の実施例を図面を用いて説明する。 The lid is pushed in by a convex part.]? The tearing guide line is torn open, but this tearing guide line does not tear open at once, but from the local part where the shear load is most applied. It begins to cleave, and then is cleaved by the process of being induced to progress to another. Therefore, the maximum value of the pressing force on the convex part is always recorded at the beginning of the initial pushing, so that after the local rupture, the tearing proceeds with extremely low pressing force. This property is clearly apparent when the lid was invented, and the planar shape of the projection is an ellipse, and the opening of the ellipse is sequentially pushed from one end to the other end of the projection. The present invention is specifically devised as a simple-opening container to be obtained. The present invention makes it possible to perform the push-in opening with a lower pressing force while utilizing the above-mentioned properties of the cutting guide line. It is an object of the present invention to provide a simple-opening container lid capable of freely obtaining an opening of the container. Hereinafter, embodiments of the present invention will be described with reference to the drawings.
この第 1 の実施例は図 1に示される。 即ち単一の薄板 1に深絞 加工をも って ¾る平面形状において小円の小凸部 2と平面形状 において大円の大凸部 3が帯状の違結凸部 4を介して形成されて ^ ) , 且つそれら凸部の周縁近傍に切断案内線 5を形成した開口 部分を含むものからなる。 This first embodiment is shown in FIG. That is, a small thin convex portion 2 in a planar shape obtained by deep drawing on a single thin plate 1 and a large convex portion 3 of a large circle in a planar shape are formed via a band-shaped misconnecting convex portion 4. ) And an opening having a cutting guide line 5 formed near the periphery of the projection.
この実施例における開口部分の押込裂開状態は図 2及び図 3に示 される。 即ち最初に小凸部 2を押圧し.小凸部 2の周縁近傍の切断 案内線 6を全周に渡って裂開するがこの場合小凸部 2の平面形状 を小さく形成しておけば、 その裂開のための押圧力は極めて低い The pushing and tearing state of the opening in this embodiment is shown in FIG. 2 and FIG. That is, first, the small convex portion 2 is pressed, and the cutting guide line 6 near the periphery of the small convex portion 2 is torn open all around.In this case, if the planar shape of the small convex portion 2 is formed small, The pressing force for its cleavage is extremely low
OMPI もので足 ] る。 OMPI Foot with something].
例えば、 厚さ 0.3腿の ア ル ミ ニゥ ム板に所定の切断案内鎳を形成 した直径 8 簡程度の凸部であれば 3 K 以下で開口することができ る。 これは指圧の限界といわれる 10 よ ] 遙かに低く、 婦人や子 供等の力の弱い者でも容易に裂開できる し、 又勢い余って開口部 に指を突込んで不慮の損傷を負う よ うな危険も防止するこ とがで き る。 も っ と も、 小凸部 2の開口部分を指の腹よ ]?相当に小さ く しておく ことによ つても これを防止するこ とができることは明ら かである。 For example, a convex part having a diameter of about 8 and having a predetermined cutting guide に formed on an aluminum plate having a thickness of 0.3 thigh can be opened at 3 K or less. This is said to be the limit of acupressure.10] It is much lower, and even weak people, such as women and children, can easily rupture, and they may accidentally injure their fingers with excessive force. Such danger can be prevented. It is clear that this can be prevented by making the opening of the small convex portion 2 substantially smaller than the finger pad.
さて、 この場合に小凸部 2が裂開するに伴い、 違結凸部 4の長 さを適当に短く しておくと、 この違結凸部 4 の両側にも形成さ れている切断案内線も誘導裂開され、 大凸部 3の周瘃に形成され ている切断案内線へ到達することになるが、 ここで凸部 3の連結 凸部 4に近い部分を押圧すと大凸部はは図 3に示すよ う な状態で 裂開する。 Now, in this case, if the length of the connecting protrusion 4 is appropriately shortened as the small protrusion 2 ruptures, the cutting guides formed on both sides of the connecting protrusion 4 are also provided. The wire is also cleaved inductively and reaches the cutting guide line formed around the large convex portion 3. Here, when the portion of the convex portion 3 close to the convex portion 4 is pressed, the large convex portion is pressed. Ruptures as shown in Fig. 3.
この 2度目の押圧力については、 既に連結凸部 4の両側の切断 案内線が裂開されて、 大凸部 3 の周縁近傍に形成された切断案内 線に繋がっているため、 単に裂開を連続させてゆ く だけの押圧力 で足 ])る。 従って、 大凸部 3 を順次押圧し切新案内線を裂開 して ゆ く押圧力は極めて低いもので充分である。 違結凸部 4が長く、 小凸部 2を裂開した時に、 裂開が大凸部 3の周緣まで誘導されな い場合には、 連結凸部 4を順次押圧裂開し、 同様の結果を得るこ とができるのは当然である。 Regarding this second pressing force, the cutting guide lines on both sides of the connecting projection 4 have already been torn and are connected to the cutting guide lines formed near the periphery of the large projection 3. Press with just enough pressure to continue. Therefore, an extremely low pressing force for sequentially pressing the large convex portions 3 to tear open the new guide line is sufficient. In the case where the connecting projection 4 is long and the small projection 2 is cleaved and the rupture is not guided to the circumference of the large projection 3, the connecting projections 4 are sequentially pressed and cleaved, and the same result is obtained. Of course.
この 2度目以降の大凸部裂開のための押圧力は、 前記と同条件 下で、 3 K?以下で足 るこ とが経験から明らかにされている。 From the experience, it has been clarified that the pressing force for the second and subsequent large cleft is less than 3 K under the same conditions as above.
( '.- QMP1 上記実施例に示すよ うに、 本発明の簡易開口容器蓋は押込押圧 力の軽減を図 ]?、 容易且つ安全に盞を開口することを可能にする ものであるが、 同時に蓋を押込開口する者に対して何処から押し 始めればよいかを指標する手段と しても都合が良いものである。 けだし、 一般的に開口者にはボタ ン状の部分を押す心理的傾向が あるといわれてお 、 蓋上に単に大凸部のみが形成されている場 合に何の知識や経験も い者はどのよ う 方法で開口するのか迷 う ときもあろうが、 かかるときに小凸部をボタ ン状に形成してお けば、 その箇所を押すことによ ]?開口するのであることを指標せ しめることが容易であろう。 ('.- QMP1 As shown in the above embodiment, the simple-opening container lid of the present invention reduces the pressing force, and enables easy and safe opening of the sandalwood. It is convenient as a means to indicate where to start pushing to the person. In general, it is said that the opener has a psychological tendency to press the button-shaped part, and there is no knowledge or experience when only a large convex portion is formed on the lid. You may be wondering how to open it, but if you make a small convex part in the form of a button at this time, it will be possible to open it by pressing that part. It will be easy to make an index.
本発明に係る簡易開口容器蓋は図 4 ， 図 5に示すよ う 種々の 形状的変容を加えたものについても可能であ ] 、 その裂開方法及 び裂開状態、 更にはその効果についても上記第 1の実施例と同様 のことがいえる。 The simple-opening container lid according to the present invention can also be applied to various modified shapes as shown in FIGS. 4 and 5], and its tearing method and tearing state, and its effect are also discussed. The same can be said for the first embodiment.
即ち、 第 2の実施例は図 4に示されるよ うに、 小凸部 7の平面 形状を小円と し、 大凸部 8の平面形状を長円とし、 且つ連結凸部 9 のを帝状と したものであ ]?、 第 3 の実施例は図 5に示すよ うに 小凸部 10の平面形状を小円又は長円とし、 この端部 11を平面形状 が大円である大凸部 12に直結させたものである。 That is, in the second embodiment, as shown in FIG. 4, the planar shape of the small convex portion 7 is a small circle, the planar shape of the large convex portion 8 is an elliptical shape, and the connecting convex portion 9 is In the third embodiment, as shown in FIG. 5, the planar shape of the small convex portion 10 is a small circle or an ellipse, and the end portion 11 is a large convex portion whose planar shape is a large circle. It is directly connected to 12.
