Description

  The present invention relates to a cookware with a handle.

  In addition to simply cutting the ingredients, cooked utensils with handles, especially kitchen knives, cut meat streaks at the cutting edge, strip potato buds with the chin, peel fruit, and decorate vegetables. It is used for many purposes. For this reason, conventional knives have been made with a thin pattern so that a fine operation can be easily performed. However, there is a problem that it is difficult to apply force to the handle when cutting hard foods.

  Therefore, in recent years, a cover has been developed that covers the handle so that the hand does not slip easily during use. For example, Patent Document 1 discloses a non-slip tool made of synthetic resin that is used by being mounted on a handle such as a cooking utensil.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

<First Embodiment>
The perspective view of the cooking utensil 1 with a handle which concerns on FIG. 1 (a)-FIG.1 (d) based on the 1st Embodiment of this invention is shown.

  As shown in FIG. 1A, the cooker 1 with a handle is a knife having a blade 11 and a handle 13.

  Specifically, the cooker 1 with a handle includes a blade 11 that is a blade portion exposed from the handle, a core 12 that passes through the inside of the handle, and a resin handle 13 that is formed around the core 12. Become.

  The blade 11 is a blade having a double-edged structure in which a blade is attached from both sides, referred to as a Western knife here. Further, the blade 11 has a rounded tip at the peak, and the peaks intersect with the blade edge at a safe angle (for example, 60 degrees or more) to form a cutting edge. The cutting edge is formed by a substantially straight and gentle curve, and the difference between the cutting edge center and the cutting edge, and the cutting edge center and the jaw is in the range of 0.5 to 3 mm, preferably about 1 mm.

  The shape of the blade 11 is not limited to this, and may be any shape. Moreover, as a raw material of the blade 11, for example, steel, stainless steel, ceramic, or the like can be used.

  As shown in FIG. 1B, the core 12 is a plate-like member formed in the same manner as a core used for a general knife. The core 12 may be formed integrally with the blade 11 or may be welded to the blade 11 after being formed of the same material or another material. The core 12 is provided with a plurality of (two in this embodiment) through-holes 121 for fixing the handle 13.

  The core 12 according to the present embodiment has a shape that passes to the middle of a pattern called a half core. If it is a half core, since all the core parts are covered with the handle 13 which will be described later, the core does not rust, and it is advantageous in that moisture does not enter the handle. Of course, it is good also as a shape with more intensity | strength, for example, the back passage which passes only to the ridge side of a handle | pattern, the main through-hole of the same shape as a handle | pattern, etc.

  As shown in FIGS. 1C and 1D, the handle 13 includes an inner member 131 that covers the core 12 and an outer member 132 that covers the inner member 131. Here, the handle 13 is formed so that its axis is substantially parallel to the cutting edge.

  The inner member 131 is a member made of a resin that is more rigid than the outer member 132 and is formed so as to cover the core 12. The composite part as shown in FIG. 1C can be manufactured by insert molding, for example. That is, the core 12 which is an insert product is loaded into the molding die of the inner member 131, molten resin is injected therein, and the core 12 is wrapped with the molten resin and solidified to be integrated. At this time, the inner member 131 and the core 12 are connected and fixed by being filled with the resin that forms the inner member 131 up to the through hole 121 of the core 12. As a material for the inner member 131, a resin having high mechanical properties such as polypropylene, ABS, polyacetal, polyamide, polycarbonate and the like is suitable.

  The connecting method of the inner member 131 and the core is not limited to the above. For example, as in the case of a general Japanese knife, the core 12 is provided with a key shape instead of the through-hole 121, insert-molded, and solidified resin Both can be connected and fixed by engaging the key shape. In addition, like a general kitchen knife, insert molding is performed after passing through the piercing through the through hole 121 and the inner member 131, and after inserting the handle, the inside is partially melted and solidified by using high frequency. Then, it may be connected and fixed.

  Further, as shown in FIG. 1 (c), the inner member 131 has a gently raised ridge 131a to prevent the thumb and index finger from moving toward the blade 11 side, and the thumb and index finger. A heel base 131b in which the handle head side of the heel 131a gently falls, and a handle head 131c in which the end of the handle is bent toward the blade edge side in order to prevent the little finger from moving to the opposite side of the blade 11 are provided.

  The outer member 132 is a member made of a softer resin than the inner member 131 and is double-molded so as to cover the inner member 131. Specifically, the outer member 132 integrally coats the molten resin using the inner member 131 of the intermediate part shown in FIG. If the outer member 132 uniformly covers the inner member 131, the hook 132a is formed according to the hook 131a, the hook 132b is formed according to the hook 131b, and the handle 132c is formed according to the handle 131c. In addition, as shown in FIG.1 (d), the collar base 132b is formed so that the collar base line M1 may incline with respect to the blade edge | tip surface M2.

  Here, the outer member 132 covers the edge of the side surface of the inner member 131, and the blade-side surface 131d is left with the inner member 131 exposed. Thus, the strength of the handle 13 can be increased by forming the joint between the handle and the blade that are easily damaged by stress using only the inner member 131 made of a rigid resin. In addition, it is resistant to impact when the knife is stored in the knife knife, and will not be cracked or cracked without providing a base.

  Although the thickness of the external material 132 is about 5-6 mm here, for example, you may shape | mold to desired thickness suitably.

  The circumference of the collar 132b of the handle 13 is preferably about 105 mm to 130 mm.

  Further, as the material of the outer member 132, for example, an elastomer such as silicon rubber or fluororubber can be used.

  In addition, the handle 13 of the cooker 1 with the handle formed in this way is processed with a good appearance by covering the outer member 132 with molding defects such as sink marks of the inner member 131 that occur during the insert molding process. Can be molded. Further, according to this, even when a pattern such as a non-slip is provided on the outer member 132, the surface is not affected by molding defects, so that the outer member 132 can be marked clearly. Moreover, if the color of an inner member and an outer member is changed, the cooking utensil excellent in the design property can be provided.

  Moreover, since the handle 13 is integrally formed by insert molding and double molding, it is easy to wash, and it is hygienic without moisture and dirt entering the inside of the handle.

  Furthermore, as described above, the cooker 1 with a handle having a thick handle is easier to apply than a conventional knife with a thin handle (about 90 mm). Further, since the handle is formed in a streamlined shape according to the user's finger, a stable and high grip property can be realized. Thereby, it is easy to apply force to the blade, and it is possible to prevent the blade from slipping and the hand from becoming painful.

  In addition, as an example, when cutting hard ingredients such as pumpkin, there is a possibility that a force enters and fingers may slip on the blade side, but this can be prevented by providing a hook on the handle 13. As a result, since anyone can safely cut hard ingredients, it is possible to cook raw ingredients as they are without sacrificing flavor using a microwave oven or the like to facilitate cooking. .

  Further, by eliminating the warp (curved part) of the cutting edge that is difficult to transmit the force from the handle and making the cutting edge almost linear, the area of the cutting edge that hits the cutting board is large as shown in FIG. It is easy to apply power to. Thereby, a hard foodstuff can also be cut easily, without producing a crack in a foodstuff.

  The above embodiments are intended to exemplify the gist of the present invention and do not limit the present invention. The present invention can be variously modified within the scope of its technical idea.

For example, the shape of the blade and the handle need not necessarily be as described above. A modification is shown below.
<Modification 1>

  2 (a) and 2 (b) show a cookware 1a with a handle according to Modification 1 of the present invention.

  The cooker 1a with a handle has a structure in which a wide portion 111 is provided on the blade 11 of the cooker 1 with a handle according to the first embodiment, and a punch-through portion 133 is provided on the handle 13.

  As shown in FIG. 2 (a), the wide portion 111 is a portion in which the peak on the cut end is raised in a curved shape in the direction in which the blade width increases. The width of the blade 11a is the widest at the wide portion 111. Thereby, when pushing down a peak by hand in order to cut | disconnect a hard thing, it can prevent that a hand slips to a cut edge side.

  Moreover, as shown in FIG.2 (b), a peak can be easily pushed by a hand by attaching the application tool 14 with a cross-section next to a peak to a peak. Moreover, it is possible to use it safely, without the applicator 14 sliding down to the cutting edge side by the wide part 111. FIG.

  The punch-through portion 133 includes a plurality (three in this case) of convex portions 1311 formed in the inner member 131 and a through hole 1321 formed at a position corresponding to the convex portion 1311 of the outer member 132. FIG. 2C is a cross-sectional view of the cross section taken along the line B-B ′ when viewed from the direction of arrow A. The convex portion 1311 is a ridge having a height at least equal to or greater than the thickness of the outer member 132, and is formed so as to penetrate the through hole 1321 of the outer member and be exposed on the surface of the handle 13a. In addition, although the shape of the penetration part 133 is made into the shape which modeled the seed of the pumpkin in this example, it is not limited to this. Further, the number of punch-through portions is not limited to the above, and may be changed as appropriate.

  With such a configuration, the cooker with a handle 1a prevents the inner member 131 from being displaced from the outer member 132 or peeled off even when a load is applied to the handle 13a. Further, by increasing the height of the convex portion 1311 or adjusting the shape and position, it is possible to provide a non-slip function by hooking the user's finger. In addition, design can be achieved by making the inner member 131 and the outer member 131 different colors.

<Modification 2>
3 (a) and 3 (b) show a cooker 1b with a handle according to a second modification of the present invention.

  The cooker 1b with a handle is connected and fixed so that the axis of the handle is inclined with respect to the blade edge of the blade 11a of the cooker 1 with a handle according to the first modification. Here, as shown in FIG. 3A, the ridge line M1 is substantially perpendicular to the cutting edge surface M2 (range of 85 to 95 degrees).

  Thereby, as shown in FIG.3 (b), a user is easy to apply force with the blade 11b. In particular, when the spine is stretched from the relationship between the height of the user and the height of the cutting board, and the elbow is bent at about a right angle and the elbow is bent at a right angle, the operation of lowering the blade 11b from top to bottom becomes easy.

<Modification 3>
4 (a) and 4 (b) show a cooker 1c with a handle according to Modification 3 of the present invention.

  The cooker with handle 1c is obtained by further increasing the width of the blade 11a of the cooker with handle 1a according to the first modification.

  Specifically, as shown in FIG. 4A, the blade 11c of the cooking utensil 1c has a blade width d2 that is at least a quarter of the blade length d1.

  In addition, as shown in FIG. 4B, generally, the sharpness of the knife is affected by the angle θ of the apex of the extension line of the sword angle. In particular, if the angle θ is reduced or the blade thickness d3 is reduced, the strength decreases even though the sharpness increases.

  Therefore, the blade 11c of this example has a blade width d2 of 45 to 55 mm, preferably about 50 mm, and a blade thickness d3 of 2 mm or less, preferably 1.4 to 1.8 mm, more preferably about 1.6 mm. By doing so, while maintaining strength, a sharp blade can be realized.

  FIG. 4 (c) shows a state in which one side of the pumpkin 5c is cut from the inside with the cooker 1c with a handle. According to this, since the cooked cooking utensil 1c has a short blade length d1, the cutting edge hits the face of the pumpkin 5c and does not get in the way and can be cut smoothly. Also, since the blade is short, the user naturally uses the cutting edge, so that the pattern force is directly transmitted to the blade and the hard food can be easily cut.

  In the above, the modification of this invention was demonstrated. In addition to the above, the present invention can be used for various purposes. For example, by applying the handle 13 to a cooker 1d with a handle as shown in FIG. 5 (frying pan) or a cooker 1e with a handle as shown in FIG. It is possible to provide a cookware with a high pattern. Further, by using a resin having high heat resistance for the inner member and low thermal conductivity for the outer member, it can be used for a cooking device. Besides, it can be applied to various cooking utensils such as spoons, forks, turners, ladle, and pan lid handles. Moreover, if it is applied to an ice scoop or a hand mixer, it can be used comfortably by preventing cold and vibration from being transmitted to the hand.

<Second Embodiment>
Next, a second embodiment of the present invention will be described.

  7 (a) and 7 (b) are perspective views of the cooker 2 with a handle according to the second embodiment of the present invention.

  As shown to Fig.7 (a), the cooking utensil 2 with a pattern is a knife which consists of the blade 21, the core 22, and the resin-made handles 23. As shown in FIG.

  The blade 21 and the core 22 are the same as those used for a general Western knife. Of course, the shape of the blade 21 and the core 22 may be any shape, and the material is also free. Here, the core 22 includes a plurality of through-holes 221 for fixing the handle 23 in the same manner as the core 11 according to the first embodiment.

  As shown in FIGS. 7A and 7B, the handle 23 includes an inner member 231 that covers the core 22 and a pair of outer members 232 that covers both surfaces of the inner member 231.

  The inner member 231 is a cube-shaped member with rounded corners made of a resin that is more rigid than the outer member 232. Further, similarly to the inner member 131 according to the first embodiment, the core 22 is covered by insert molding and is connected and fixed to the blade 21.

  The outer member 232 is a member having a bowl-shaped cross section made of a softer resin than the inner member 231. The outer member 232 is attached and fixed to both surfaces of the inner member 231 by outsert molding. In addition, the pattern 100 for anti-slip | skid etc. can be attached | subjected to the outer member 232 by forming the unevenness | corrugation for a pattern in the casting_mold | template used for outsert molding.

  According to such a configuration, the cooker 2 with a handle according to the present invention has the outer member 232 attached and fixed to the inner member 231 by outsert molding. Use is possible. Moreover, the hard member can be cut more safely by the outer member 232 using a soft resin having a high grip property.

  Thus, according to the present invention, by providing the handle of the cooker with a handle from a hard resin and a soft resin, a cooker with a handle that is hygienic and has an excellent grip feeling is provided.
