Definitions

  • the present invention relates to a simple opening container lid used for a container such as a can of soft drink, oil and the like.
  • the purpose of this invention is to eliminate the various problems of the conventional tear-opening type simple opening container lid and other push-in type simple opening container lids. The result is enough to solve the problem.
  • the present invention is a further improvement of the simple opening container lid according to the international application.
  • 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.
  • 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.
  • FIG. 2 and FIG. 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
  • a convex part having a diameter of about 8 and having a predetermined cutting guide ⁇ 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.
  • 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.
  • the large convex portion is pressed. Ruptures as shown in Fig. 3.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • the connecting convex portion 9 is
  • the planar shape of the small convex portion 10 is a small circle or an ellipse
  • the end portion 11 is a large convex portion whose planar shape is a large circle. It is directly connected to 12.
  • FIG. 1 is a perspective view of an opening according to one embodiment of the present invention
  • FIGS. 2 and 3 are cross-sectional views and oblique views of a main part showing a split state of the opening according to the embodiment
  • 5 is a perspective view of an opening according to another embodiment
  • FIG. 6 is a perspective view showing a best mode for carrying out the invention.
  • 1 is a thin sheet of a container
