Definitions

  • the present invention relates to a container for packaging food, and particularly to a container with a cutting knife that allows the plastic wrap to be easily cut and removed.
  • Disposable containers are being widely used as the culture of providing packaged food is spreading, such as providing delivery food or take-out food.
  • These disposable containers are generally made of plastic, and the upper surface is open to form an entrance, and the entrance is covered with plastic wrap and then fused to prevent the packaged food from spilling out.
  • the consumer removes the plastic wrap covering the entrance and consumes the food contained in the container.
  • sharp tools or knives are used, which causes various inconveniences, such as having to prepare such tools separately.
  • the purpose of the present invention is to provide a means that anyone can easily use to easily remove the plastic wrap covering the mouth of the container.
  • a cutting knife is formed to be detachable on one side of the container, and the cutting knife is plate-shaped and has an ' ⁇ ' shaped cutting line forming a tip at one edge, and the cutting knife is cut along the cutting line.
  • a container with a cutting knife that can cut the plastic wrap covering the container with the tip by removing part of the knife to expose the tip.
  • the cutting knife can be provided together with the container, so the cutting knife can be used without the risk of loss.
  • the tip of the cutting knife is not normally exposed, but can be exposed and used when cutting plastic wrap. Therefore, it is possible to prevent the tip from being damaged before using the cutting knife, and also prevent the user from getting hurt by the cutting edge, and can use it conveniently.
  • FIG. 1 is an illustration showing a state in which a cutting knife is formed in a container according to the present invention
  • Figure 2 is an illustration showing a state in which a cutting knife is separated from a container according to the present invention
  • Figure 3 is an illustration showing the folding process for using the cutting knife according to the present invention.
  • Figure 4 is an illustration of the state of use of the cutting knife according to the present invention.
  • Figure 5 is another example of a cutting knife according to the present invention.
  • a cutting knife is formed on one side of the container to be detachable, and the cutting knife has a plate shape.
  • An ' ⁇ '-shaped cutting line forming a tip is formed on one edge, and a part of the cutting knife is removed along the cutting line to expose the tip, thereby cutting the plastic wrap covering the container with the tip.
  • Figure 1 is an example showing a state in which a cutting knife is formed in a container according to the present invention
  • Figure 2 is an example showing a state in which a cutting knife is separated from a container according to the present invention
  • Figure 3 is an example showing a state in which a cutting knife according to the present invention is used. This is an example showing the folding process.
  • the cutting knife 100 is formed on one side of the container 200 so that it can be separated.
  • the cutting knife 100 is provided together with the container 200, so there is no need to provide the cutting knife 100 separately, so when the user wants to use the cutting knife 100 without the risk of losing it, it can be separated from the container 200. It becomes usable.
  • the cutting knife 100 may be made of a plastic material, or alternatively, it may be made of a material such as paper. Furthermore, it is also possible to be formed of a metal material.
  • the cutting knife 100 may be formed integrally with the edge of the container 200.
  • a separation line 120 is formed at the point where the container 200 and the cutting knife 100 are connected.
  • the separation line 120 is a cutting line, and when the cutting knife 100 is held and pulled by hand, the cutting knife 100 is separated from the container 200 along the separation line 120.
  • the cutting knife 100 has a plate shape.
  • An incision line 140 is formed in the shape of an ' ⁇ ' on one edge, and has the same structure as a sheath.
  • a sharp tip 160 in the shape of an ' ⁇ ' shape is formed on the cutting knife 100 in the shape of the cutting line 140.
  • This tip 160 is not exposed in normal times, but is exposed in a protruding state when a part of the cutting knife 100 is removed along the incision line 140. Accordingly, it is possible to prevent the tip 160 from being damaged before using the cutting knife 100, and furthermore, it is possible to prevent problems such as the user being injured by the tip 160.
  • the cutting knife 100 may be formed with a fold line 180. It is formed at the point where the body is cut in half, and is formed at a position that coincides with the point where the tip 160 is cut in half.
  • This fold line 180 may be formed in a structure in which a line is drawn or a concave groove is formed linearly, and when the cutting knife 100 is folded along this fold line 180, the tip portion 160 naturally forms. It also folds in half.
  • the cutting knife 100 and the tip 160 are folded in half as described above, the overall strength is improved. Accordingly, the cutting knife 100 and the tip 160 are not easily bent or distorted by external force, thereby ensuring structural stability.
  • the cutting knife 100 may be formed in a square shape. In this configuration, the tip 160 is formed at one of the four corners of the square-shaped cutting knife 100. By forming the cutting line 140 at one of the corners, the tip 160 is formed without being exposed to the outside. In this configuration, the remaining three corners are rounded, which prevents problems such as scratches on the corners and injuries to the user.
  • Figure 4 is an exemplary state of use of the cutting knife according to the present invention.
  • the cutting knife 100 is used by removing it from the container 200 and then exposing the tip 160. Preferably, it is used by folding it in half as described above, and the plastic wrap 220 covering the entrance of the container 200 is cut with the tip 160.
  • the cutting knife 100 and the tip 160 do not bend easily even if a relatively large force is applied, effectively cutting the plastic wrap 220. It becomes possible to cut it.
  • Figure 5 is another example of a cutting knife according to the present invention.
  • the cutting knife 100 according to the present invention described above can form a curved structure by alternately forming convex portions 192 and concave portions 194.
  • the convex portion 192 and the concave portion 194 are formed in a direction parallel to the tip 160, that is, in a direction parallel to the fold line 180.
  • the convex portion 192 and the concave portion 194 as described above may be formed in a semicircular, triangular, or square shape, and when the convex portion 192 and the concave portion 194 form a curved structure, they are cut. Since the strength of the knife 100 is improved, even thick plastic wrap can be effectively cut.
