Description

cake knife

[0001] The present invention relates to a cake knife, and more particularly, to an integrated, foldable cake knife.

[0002] There was an inconvenience in that when cutting a cake on a birthday, you had to use the knife twice because there was only one knife.

[0003] To solve this problem, as shown in FIGS. 1 and 2, two interchangeable cake cutting knives are proposed in Korean Patent Publication No. 20-1992-0017831.

[0004] Fig. 1 is a plan view of two conventional cake knives, and Fig. 2 is an enlarged view of part "A" of Fig. 1, in which two cake cutting knives (1) having conventional cake knife handles (2) are formed with a slide tube (4) at the upper end of one knife so that they can be inserted and removed from each other, and a slide rod (3) is formed at the upper end of the other knife (1), thereby connecting the two knives (1). When in use, the slide rod (3) of one knife (1) is inserted into the slide tube (4) of the other knife (1).

[0005] As described above, the two cake cutting knives (1) have to be manufactured separately so that one side of the knife (1) is equipped with a slide body (4) and the other side of the knife (1) is equipped with a slide rod (3), which increases the manufacturing cost. In particular, if the slide rod (4) is equipped, the mold cost, etc. increase, and since the slide rod (3) and the slide body (4) must be manufactured to be slidably connected, there is a problem that the quality must be strictly controlled. In addition, since it can only be used for cutting cakes, there is a problem that a separate mechanism is required to transfer the cut cake to a plate, etc.

[0006] The present invention has been proposed to solve the problems of the above-mentioned prior art, and aims to provide a cake knife that is manufactured with a single cake knife, thus reducing manufacturing costs, eliminating the need for strict tolerance management during the manufacturing process, and is convenient to use and does not require any separate mechanism.

[0007] For the above purpose, the present invention provides a cake knife for cutting a cake;

[0008] A cake knife is provided, which includes cutting sections provided on both sides of a bendable bending portion, and is characterized in that the cutting sections on both sides are bendable at the bending portion.

[0009] In the above, the cutting part includes a cutting upper part and a cutting lower part provided with an upper part and a lower part of a bendable first bending part; and the cutting lower part is characterized in that it can be bent inward with respect to the cutting upper part.

[0010] In the above, the cutting lower part is characterized by having a sloped portion on the inner side in the width direction.

[0011] In the above, the lower cutting portion is characterized by including a handle portion that protrudes outward in the width direction more than the upper cutting portion.

[0012] The cake knife according to the present invention can be manufactured as a single cake knife, thus reducing manufacturing costs and simplifying manufacturing. Furthermore, it is convenient to use because it does not require any joining or other processes for use, and strict tolerance management is not required during the manufacturing process. Furthermore, the cut cake can be easily lifted and transferred to a plate or other device without the need for a separate tool.

[0026]

[0027] For convenience of explanation, in the following description, the horizontal direction of Fig. 3 is referred to as the width direction, the vertical direction as the up-down direction, the direction toward the bending portion (120) is referred to as the width direction inward, and the direction toward the handle portion (117) is referred to as the width direction outward. In addition, as illustrated in Fig. 4, when the cutting portion (110) is bent, the side where the two cutting portions (110) face each other is referred to as the inner side or the inner surface.

[0028]

[0029] As illustrated in Fig. 3, the cake knife (100) according to the present invention has a length longer than its vertical width and is provided in the form of a thin plate. The cake knife (100) is manufactured from a synthetic resin such as plastic.

[0030] The cake knife (100) comprises a bending portion (120) and cutting portions (110) provided on both sides of the bending portion (120). The cutting portions (110) are provided on both sides of the bending portion (120) so as to be foldable at the bending portion (120). Since the cake knife (100) is structured to be folded at the bending portion (120), the cutting portions (110) on both sides can be manufactured as one piece, making it easy to manufacture and reducing manufacturing costs.

[0031] The above-mentioned bending portion (120) is formed between the cutting portions (110) on both sides. The above-mentioned bending portion (120) is formed on the inner surface. The above-mentioned bending portion (120) is formed as a concave groove extending in the vertical direction. The above-mentioned bending portion (120) extends in the vertical direction to the end.

[0032] The above cutting portion (110) is provided on both sides in the width direction of the above bending portion (120). The above cutting portion (110) is bent on both sides in the width direction of the above bending portion (120) so that the cutting portions (110) on both sides face each other with the above bending portion (120) as the center.

[0033] As illustrated in Fig. 4, the cake knife (100) is bent at the bending portion (120) so that the angle (θ) between the cutting portions (110) on both sides becomes smaller than 180°. The cake knife (100) can be used at various angles by adjusting the angle (θ) between the cutting portions (110) on both sides by bending at the bending portion (120).

[0034] In addition, the cutting portions (110) on both sides are bent at the bending portion (120) so as to have an angle (θ) smaller than 180°, and when cutting the cake (C) in the bent state, the cake (C) can be cut and separated with one cut, which is efficient.

[0035]

[0036] The above cutting portion (110) is provided on both sides in the width direction of the above bending portion (120). The cutting portions (110) on both sides are shown in a symmetrical shape with the same length in FIG. 3, but the cutting portions (110) on both sides may be provided to have different lengths.

[0037] The above cutting part (110) is composed of a first bending part (115), and a cutting upper part (111) and a cutting lower part (113) provided at the upper and lower portions of the first bending part (115).

[0038] The first bend portion (115) is spaced apart from the upper and lower ends of the cutting portion (110) and extends in the width direction to the cutting portion (110). The first bend portion (115) may be formed as a concave groove extending in the width direction on the inner surface of the cutting portion (110). The first bend portion (115) extends to the width direction outer end of the cutting portion (110). The width direction inner end of the first bend portion (115) may extend to the lower end of the bend portion (120) or may be positioned spaced apart in the width direction outward from the lower end of the bend portion (120). The first bend portion (115) may be formed to intersect the lower end of the bend portion (120).

[0039] The above cutting upper portion (111) is provided on both sides in the width direction of the above bending portion (120). The above cutting upper portion (111) is provided to extend in the width direction on both sides of the above bending portion (120). The above cutting upper portion (111) is provided as an upper portion of the above first bending portion (115).

[0040] The above cutting lower part (113) is provided as the lower part of the first bending part (115). The above cutting lower part (113) is provided as the lower part of the first bending part (115) and extends downwards from the lower end of the bending part (120). The above cutting lower part (113) extends in the width direction from the lower part of the above cutting upper part (111).

[0041] The cutting lower portions (113) on both sides are provided with their widthwise inner sides separated from each other. The cutting lower portions (113) on both sides may also be provided with their widthwise inner ends spaced apart from each other. The upper ends of the cutting lower portions (113) on both sides may be spaced apart from each other. The widthwise inner upper ends of the cutting lower portions (113) on both sides may be located at the intersection of the bending portion (120) and the first bending portion (115).

[0042] The above cutting lower part (113) is formed to protrude outwardly in the width direction from the outer end of the cutting upper part (111) in the width direction, and the part protruding outwardly in the width direction from the cutting upper part (111) becomes a handle part (117). By providing the handle part (117), the cake knife (100) can be conveniently used by holding the handle part (117) when used.

[0043] The above cutting portion (110) includes a cutting upper portion (111) and a cutting lower portion (113) provided at the upper and lower portions of the first bending portion (115), respectively, such that the cutting lower portion (113) can be bent inward with respect to the cutting upper portion (111). The cutting lower portion (113) is provided so as to be bendable with respect to the cutting upper portion (111) by the first bending portion (115).

[0044] As shown in Fig. 5, the cutting lower part (113) is bent inward at the first bending part (115), so that the angle (θ1) between the cutting lower part (113) and the cutting upper part (111) is less than 180°, and can be bent at 90° so that the cut cake (C) is well supported.

[0045] As shown in the arrow "A" direction of Fig. 4, when the lower part of the cutting lower part (113) of the above cutting part (110) is pulled inward, the cutting lower part (113) is bent at the first bending part (115) as shown in Fig. 5, and the cutting lower part (113) enters the lower part of the cake (C) cut from both sides.

[0046] The above-mentioned bending part (120) is bent to cut the cake, and the cutting lower part (113) is bent inward (direction "A" in FIG. 4) so ​​that the cutting lower part (113) enters the lower part of the cut cake (C) from both sides, and in this state, the cut cake (C) can be lifted by applying pressure in the direction of arrow "B" in FIG. 4, so that the cutting motion and the lifting and separating of the cut cake (C) can be performed continuously. In addition, the cut cake (C) can be lifted while being supported by the cutting lower part (113) from both sides, so that the cut cake can be lifted stably.

[0047]

[0048] As illustrated in Fig. 3, the two-sided cutting lower portions (113) may further be provided with an inclined portion (1131) on the inner side in the width direction. The distance between the two-sided cutting lower portions (113) increases as they go downward from the inner side in the width direction.

[0049] The above cutting lower part (113) is provided with an inclined portion (1131) on the inner side in the width direction so that the lower portions of the cutting lower parts (113) on both sides are spaced apart from each other on the inner side in the width direction. With the inclined portion (1131) provided, when the cutting lower parts (113) on both sides are bent at the first bending portion (115), the cutting lower parts (113) on both sides may not overlap each other.

[0050] When the lower cutting parts (113) on both sides are bent at the first bending part (115) according to the bending angle (θ) of the cutting parts (110) on both sides and the angle of the inclined part (1131), the inclined parts (1131) on both sides may face each other as shown in FIG. 6, a gap may be formed between the inclined parts (1131) on both sides, or the inclined parts (1131) on both sides may overlap each other. However, since the inclined parts (1131) are provided, when the lower cutting parts (113) on both sides are bent at the first bending part (115), interference between them is reduced, so that the lower cutting parts (113) can be easily bent.

[0051]

[0052] As described above, the cake knife (100) according to the present invention can be manufactured with one cake knife, so that the manufacturing cost is reduced and the manufacturing can be done simply. In addition, since it is manufactured with one cake knife, there is no need for strict tolerance management during the manufacturing process.

[0053]

[0054] The cake knife according to the present invention can be manufactured with a single cake knife, thereby reducing manufacturing costs and making it simple to manufacture. In addition, since strict tolerance management is not required during the manufacturing process, defects are prevented, thereby reducing costs by preventing waste of materials.
