AI Technical Summary
Existing cup noodle container lid seal materials lack sufficient strength and functionality in their re-sealing mechanism, particularly in maintaining the shape and effectiveness of the folding tabs, which are symmetrical and easily detachable.
The lid seal material incorporates tabs with a minimum width of 1 mm on both wings, allowing for two-fold folding, with a central tip that is bent to enhance the locking function, and a curved depression to fit the container's curved body, enhancing the re-sealing capability.
The enhanced lid seal material provides a robust re-sealing function by ensuring the tabs are securely locked to the container flange, improving the re-sealing effectiveness and durability.

Abstract
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] In the prior art, a typical resealing technique involved providing a protrusion around the outer edge of the lid seal of a cup noodle container, and after pouring hot water into the cup noodles, folding this protrusion onto the side of the cup container body to lock and secure it in place. However, there is a technology in which tabs are provided in the longitudinal direction on both wings of this protrusion to provide a locking function that allows the protrusion to be easily locked and secured to the container body, and these tabs can be folded symmetrically from left to right. The folded tabs and the tip of the protrusion are overlapped in two layers, and part of the tab is simultaneously folded in a mountain fold to lock it into the flange of the container body, thereby increasing the strength of the protrusion and maintaining the resealing locking function of the lid. In addition, the shapes of cup noodle containers and lid sealing materials up to now have generally been configured with protruding parts as folding tabs, and the locking function of folding the tip of the protruding part parallel to the container body and locking it into the flange is widely known as a ready-made technology. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent No. 7076625 Publication 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, the protruding parts of the lid seal material are folded in two or three stages to engage with the container body, which gives strength to the engagement function of the protruding parts with a multi-layer structure of two to four layers, thereby realizing an enhanced engagement function with the flange part of the container body. 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 parts, but as a technology that focuses on the folding process, it is also necessary to seek the effect of a different approach, and with the aim of achieving a more effective shape similarity and improved functionality, it was necessary to establish a technology that derives from the effect of the prior art when the issue of enhancing the functionality of "length" and "width" from the shape of the protruding parts of existing products is addressed. [Means for solving the problem]
[0005] In order to achieve the above-mentioned object, the present invention provides a structure in which tabs having a length and width of at least 1 mm or more are provided on both wings of the protrusion portion of a prefabricated lid seal material, and these tabs can be folded in half, and in a first step, when the central tip portion of the protrusion portion is the front portion and the base portion of the protrusion portion that contacts the lid seal material at a wide angle is the rear portion, the central portions of the front and rear are appropriately folded in a mountain fold to give the central tip portion of the protrusion portion a shape that can exert its locking function so as to engage with the flange of the container body, and in a second step, both wing tab portions and a part of the folded protrusion portion are folded simultaneously to strengthen the locking function.
[0006] The tip of the protruding portion of the lid seal material is characterized in that it has a curved recess so that when the tip is bent, it fits into the curved shape of the lower part of the flange portion of the container body. Effect of the Invention
[0007] As described above, in the technology of the present invention for resealing the container body and lid sealing material, by carrying out a second step of folding both wing tabs around the protrusion portion folded in the first step, a folding action is applied to both wings of the central tip portion of the protrusion portion that is engaged as described above, and the engagement function of the tip portion of the protrusion portion is strongly fixed by the folding effect consisting of two and three layers, and the action of engaging with the flange portion becomes a strong engagement function different from the prior art. In addition, the curved recess in the protrusion portion is shaped to fit into the curved side portion of the container body when the protrusion portion is folded in a mountain fold in the first step, thereby widening the engaging area, and the engaging function of the flange of the container body also applies over a wide curved area, and the wider the engaging area, the greater the effect. From the above, the effect of the present invention is that it overcomes the previous weaknesses and achieves improved resealing function. [Brief description of the drawings]

[0010] 1 to 4, 1 indicates the lid seal material, a indicates the front side, and b indicates the back side. 2 indicates the protruding portion, 3 indicates the crease for folding the protruding portion, 4 indicates the first step of folding the protruding portion 2 into a mountain fold, and 4 indicates the two wing tab portions of the second step of folding both wings of the folded protruding portion 2 into a valley fold. The tip portion of the protruding portion 2 shown in Fig. 4 shows a mode in which the locking function is strengthened by the folding portions of the two wing tab portions 4 shown in Fig. 3.
[0011] 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 2 from the side in terms of the dynamic action effect. As shown in the figures, the protrusion 2 is a locking piece provided on the lid seal material 1, and an appropriate central portion from the tip of the protrusion 2 is folded in a mountain fold 3 so as to engage with the flange portion 6. In addition, the folded protrusion 2 is fixed so that the tip of the protrusion 2 does not spread out by folding both wing tab portions 4 in a valley fold, and the function of fitting with the flange portion 6 is given, thereby showing that the resealing function is enhanced.
[0012] 9 to 11 show perspective views of the plan views of FIGS. 1 to 4 and the side views of FIGS. 5 to 8. In FIG.
[0013] In Figures 12 to 15, 7 indicates that a curved recessed portion is provided at the tip portion of protrusion portion 2, and when the tip portion of protrusion portion 2 shown in Figures 1 to 11 is bent, recessed portion 7 engages with the step of flange portion 6, and the curved recessed portion 7 is shaped to fit into the cylindrical curved side portion that forms container body 5, and these recessed portions 7 indicate that the tip portion of protrusion portion 2 can exhibit a wide range of locking functions. EXAMPLES
[0014] An effective function of the lid seal material 1 will now be described as an embodiment. The resealing function technology shown in Figures 1 to 15 is a technology that can be used for existing instant noodle containers and confectionery products, as well as other containers and lid sealants, and is a technology that can be realized with existing shapes, but this is an example in which the folding effect can be dramatically improved by forming the existing shape into a width and length of at least 1 mm or more. [Industrial Applicability]
[0015] 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.
