Description

[Technical field]

[0001] The present invention relates to a technique for fixing peeling of a lid sealant of a cup noodle container. [Background technology]

[0002] The technology of the original application of Patent Application No. 2023-117264 involves providing a protrusion on the outer edge of the lid sealing material of a cup noodle container, and after pouring hot water into the cup noodles, providing both wing tab portions on this protrusion in a first process of folding it parallel to the flange portion of the container body, and then performing a second process of making a valley fold on both ends of the folded wing tab portions, so that the tip portions of the protrusion portions folded in the first process catch on the flange, thereby enhancing the resealing function. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent application No. 2023-117264 Summary of the Invention [Problem to be solved by the invention]

[0004] As for the function of the lid seal material for sealing conventional cup noodle containers as described above, by applying two-stage folding to both wing tabs of the protruding part of the lid seal material to engage with the container body, the strength of the engagement function of the protruding part is given to the engagement function of the flange part of the container body by multiple layers of two to three layers, and the engagement function of the flange part of the container body is strengthened. These technologies address the issue of how to strengthen the folding core effect of the engagement part, which is the tip part of the protruding part, and as a technology focusing on the folding process, it was necessary to seek the effect of a different approach. If the objective was to expand the technology of the original application with the aim of improving the effective shape, similarity, and functionality derived from the technology of the original application, it was necessary to establish the effect of the prior art as a technology. [Means for solving the problem]

[0005] In order to achieve the above object, the present invention considers the minimum to maximum application of the shape of the protrusion and the shape of the tab, and the fusion of the technology of the original application with the existing products currently on the market. It has been found that if the tabs on both wings are tabs on only one side, even if a tab is provided on one side of the symmetrical protrusion and the second step is performed, the tip of the protrusion bent in the first step is difficult to open, and the strength of the resealing function is inferior to that of the tabs on both wings in the original application, but the effect is sufficient. When the shape of the protrusion is changed, the crest-like shape of the central tip of the protrusion is formed slightly narrower in the width direction, and the protrusions toward the tabs on both wings become gently crest-like, and the range of the part connected to the flange as a locking function is widened. In addition, when there are two or more protrusions, the tabs connected to the protrusions located on both sides become strip-shaped edges like paddles between the respective protrusions, and are formed along the outer periphery of the container body. The first step of folding these protrusions on both sides together with the band-shaped edge tabs against the flange allows for a wide engagement function. In addition, the second step of folding both ends of the protrusions into valley folds allows the protrusions on both sides to exert the same effect as the wing tabs, which is a distinctive feature of this technology, and it has been established as a derived technology. Effect of the Invention

[0006] As described above, in the technology for resealing the container body and lid sealing material of the present invention, by carrying out a second step of folding either the left or right tab portion, both wing tab portions, and two or more protrusion portions and the band-shaped edges which are tab portions connected to these, around the protrusion portion folded in the first step, a folding action can be applied to the central tip portion and both wings or either the left or right tab portion of the protrusion portion which is engaged as described above, and the engagement function of the protrusion portion is firmly fixed by the folding effect consisting of two and three layers, and becomes capable of engaging with approximately the flange portion. From the above, the effect of the present invention is that it has the same effect as the function invented in the original application, and by making the shape derived from the previous function, it has been possible to achieve improved resealing function as a technology that complements the invention of the original application.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. Figure 8 The explanation will be based on the above.

[0009] 1 to 3, 1 indicates a lid seal material, and a indicates a surface. 2 indicates a protruding portion, 3 indicates a crease for folding the protruding portion, 4 indicates a first step of folding the protruding portion 2 into a mountain fold, and 4 indicates a one-side tab portion of a second step of folding one side of the folded protruding portion 2 into a valley fold, and the tip portion of the folded protruding portion 2 shows an aspect in which the locking function is strengthened by the folding portion of the one-side tab portion 4 shown in FIG. In addition, although there is an A notation in Figures 1 to 3, in order to indicate that the one-sided tab formed on the protruding portion can be formed on either the left or right side, Figures 1 to 3 use the A notation, while Figure 4, which shows the one-sided tab located symmetrically on the opposite side, uses the B notation.

[0010] In Figures 5 to 8, 5 denotes the container body, 6 denotes a flange portion provided on the upper edge of the container body, and Figures 5 to 8 show the locking function of the protrusion portion 2 from the side in terms of the dynamic action effect. As shown in the figures, the protrusion portion 2 is a locking piece provided on the lid seal material 1, and an appropriate central portion from the tip portion of the protrusion portion 2 is folded in a mountain fold 3 so as to engage with the flange portion 6. In addition, by folding the tab portion 4 on either the left or right side of the folded protrusion portion 2 in a valley fold, the tip portion of the protrusion portion 2 is fixed so as not to spread out, and the function of fitting into the flange portion 6 is given, which indicates that the resealing function is enhanced. 。 EXAMPLES

[0011] An effective function of the lid seal material 1 will now be described as an embodiment. From Figure 1 Figure 8 The resealing function technologies up to this point are derived from the invention of the original application and are intended to improve the resealing function of the lid seal material. In this invention, securing a foldable portion to make the function of the protruding portion into a foldable shape is an important part and a feature of the invention. These invention technologies can be used for pre-made instant noodle containers and confectionery, as well as other containers and lid seal materials, and are technologies that can be realized with existing shapes, but they are technologies that can dramatically improve the folding effect by widening or narrowing the length in the longitudinal direction and / or the width in the width direction along the outer edge of at least 1 mm in the existing shape. We believe that these invented technologies can contribute to manufacturing costs because they can be realized simply by changing the shape of the lid sealant. Among the publicly known lid fastening and resealing ideas, this is one example in which the lid fastening can be done with simple steps that anyone can do without requiring any tools to hold the lid in place. [Industrial Applicability]

[0012] This technology contributes to sales promotion by enabling the production of cup noodles and resealable containers, as well as differentiation through new functionality. It is particularly cost-effective in the production of food products such as cup noodles, and is expected to have ample market value, making it suitable for use in related business formats.
