Abstract
Description
[Technical field]
[0001] The present invention relates to a container for packaging food, and more particularly to a container with a cutting blade that allows a plastic wrap to be easily cut and removed by forming a cutting blade. [Background technology]
[0002] As the culture of providing packaged food spreads, such as the generalization of food delivery and takeaway services, disposable containers are widely used. Such disposable containers are generally made of plastic and have an opening at the top to form an entrance, which is covered with plastic wrap and then fused to prevent the packaged food from leaking.
[0003] As described above, when food is served with the opening covered with plastic wrap, consumers must remove the plastic wrap from the opening before eating the food in the container. In this process, sharp tools or blades are used, which causes various inconveniences, such as the need to prepare such tools separately. Summary of the Invention [Problem to be solved by the invention]
[0004] An object of the present invention is to provide a means that is easy for anyone to use and allows for the easy removal of vinyl wrap covering the opening of a container. [Means for solving the problem]
[0005] In order to achieve the above-mentioned object, the present invention proposes a container with a cutting blade, in which a cutting blade is formed detachably on one side of a container, the cutting blade is plate-shaped, and a V-shaped incision line is formed on one side edge to form a pointed end, and by removing a part of the cutting blade along the incision line to expose the pointed end, the plastic wrap covering the container can be cut by the pointed end. Effect of the Invention
[0006] According to the present invention, the cutting blade is provided together with the container, so that the cutting blade can be used without the risk of losing it. In particular, the sharp tip of the cutting blade is not normally exposed, but can be exposed and used when cutting vinyl wrap, which prevents the sharp tip from being damaged before the cutting blade is used and prevents the user from being injured by the sharp tip, making it easy to use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] In the following, the present invention proposes a container with a cutting blade, in order to provide a means that is easy for anyone to use and allows for easy removal of vinyl wrap covering the entrance of a container, in which a cutting blade is formed on one side of a container in a detachable manner, the cutting blade is plate-shaped and has a V-shaped incision line formed on one side edge that forms a pointed end, and by removing a part of the cutting blade along the incision line to expose the pointed end, the vinyl wrap covering the container can be cut by the pointed end.
[0009] The present invention will now be described in detail with reference to the accompanying drawings, FIGS.
[0010] FIG. 1 is an example diagram showing a state in which a cutting blade is formed on a container according to the present invention, FIG. 2 is an example diagram showing a state in which the cutting blade is separated from the container according to the present invention, and FIG. 3 is an example diagram showing a process of folding the cutting blade according to the present invention for use.
[0011] In the container with a cutting blade according to the present invention, the cutting blade 100 is formed detachably on one side of the container 200. Since the cutting blade 100 is provided together with the container 200, the cutting blade 100 does not need to be provided separately.
[0012] Therefore, when a user wishes to use the cutting blade 100, the user can remove it from the container 200 and use it without worrying about it being lost.
[0013] The cutting blade 100 may be made of a plastic material, a paper-like material, or a metal material.
[0014] The cutting blade 100 may be integrally formed on the edge of the container 200, and in this configuration, a separation line 120 is formed at the point where the container 200 and the cutting blade 100 are connected. The separation line 120 is a tear line, and when the cutting blade 100 is picked up by hand and pulled, the cutting blade 100 is separated from the container 200 along the separation line 120.
[0015] The cutting blade 100 is plate-shaped. A V-shaped incision line 140 is formed on one side edge, which is a structure with a notch. When the incision line 140 is formed as described above, a V-shaped pointed tip 160 is formed on the cutting blade 100 according to the shape of the incision line 140. The pointed tip 160 is not usually exposed, but when a part of the cutting blade 100 is removed along the incision line 140, it becomes exposed while protruding. Therefore, it is possible to prevent the pointed tip 160 from being damaged before the cutting blade 100 is used, and further, it is possible to prevent inconvenience such as the user being injured by the pointed tip 160.
[0016] The cutting blade 100 may have a fold 180 formed at a point where the body is halfway and where the tip 160 is halfway. The fold 180 may be formed in a lined structure or a linear grooved structure, and when the cutting blade 100 is folded along the fold 180, the tip 160 is naturally folded in half as well.
[0017] Meanwhile, when the cutting blade 100 and the tip 160 are folded in half as described above, the overall strength is improved, and the cutting blade 100 and the tip 160 are not easily bent or crushed by external forces, so structural stability is ensured.
[0018] The cutting blade 100 may be formed in a rectangular shape. In this configuration, a pointed tip 160 is formed at any one of the four corners of the rectangular cutting blade 100. An incision line 140 is formed at any one of the corners, so that the pointed tip 160 is formed without being exposed to the outside. In this configuration, the remaining three corners are chamfered, which can prevent inconvenience such as a user being scratched by the corners.
[0019] FIG. 4 is an exemplary view showing a state in which the cutting blade according to the present invention is used.
[0020] After removal from the container 200, the cutting blade 100 of the present invention is used with the tip 160 exposed. Preferably, as described above, the cutting blade 100 is folded in half for use, with the tip 160 cutting the vinyl wrap 220 covering the inlet of the container 200. When the cutting blade 100 is folded in half and the vinyl wrap 220 is cut, the cutting blade 100 and tip 160 are less likely to bend, even when a relatively large force is applied, so that the vinyl wrap 220 can be effectively cut.
[0021] FIG. 5 is an exemplary view showing another embodiment of a cutting blade according to the present invention.
[0022] The cutting blade 100 according to the present invention described above can have a curved structure by alternately forming the convex portions 192 and the concave portions 194. The convex portions 192 and the concave portions 194 are formed in a direction parallel to the pointed end 160, i.e., in a direction parallel to the fold line 180, and at this time, the positions of the convex portions 192 and the concave portions 194 are formed in opposite positions with respect to the fold line 180, so that when the cutting blade 100 is folded in half, they are completely overlapped and folded.
[0023] The convex portions 192 and concave portions 194 as described above can be formed in a semicircular, triangular, rectangular, or other shape. When the convex portions 192 and concave portions 194 are formed in this manner to form a curved structure, the strength of the cutting blade 100 is improved, so that even thick vinyl wrap can be effectively cut.
