Abstract
Description
Technical Field
[0001] The present invention relates to a collar core used when wearing a kimono.
Background Art
[0002] The collar core serves as the base of the collar of the undergarment worn under the kimono. When wearing the undergarment of a kimono, the presence of a collar core as a base causes it to follow the collar of the kimono, resulting in an effect of looking neat and clean. Collar cores include those with a slender and straight shape, a slightly curved shape, and a bridal collar core. The materials of the collar core include polyethylene, nylon, polypropylene, kozo paper, paper core, cloth core, etc. Collar cores are also used for kimonos in general and bridal dresses. Conventional collar cores are inserted into the collar. Or, it is necessary to perform a sewing operation of sandwiching the collar core between the collars and folding and sewing it to the collar width. There is also a case where a fabric collar core with tension is sewn and worn on the collar, or a fabric collar core with tension is sewn and worn on the outer collar (see Fig. 7).
[0003] Patent Document 1 discloses a collar core for a haori that has cuts in a substantially inverted mountain shape from the center of the collar width of a horizontally long rigid core plate, and the collar core is inserted into the collar and sewn and folded along the cuts.
[0004] Patent Document 2 is formed of a crescent-shaped polymer core (reference numeral 5 in this Patent Document 2) at the center of the collar of a fabric piece of the collar core and a strip-shaped polymer core (reference numeral 9 in this Patent Document 2) with a slight gap between the outer curved sides at both left and right ends. The strip-shaped polymer core is a collar core that folds in half along the gap, and due to the presence of a cut (reference numeral 10 in this Patent Document 2) at the center of the crescent polymer core, the pleat part is formed in a V shape and serves as a center mark. Note that this cut only enters the crescent-shaped polymer core and does not enter the fabric piece below it. That is, the so-called hole due to this cut is not open.

[0005] [Patent Document 1] Utility model registration: 1986-120702 [Patent Document 2] Utility model registration: 59-8961 Summary of the Invention [Problem to be solved by the invention]
[0006] In Patent Document 1, when the collar stiffener is inserted into the collar and folded, the collar is thick enough with just the cuts (symbols 2 and 3), so the collar stiffener on the inside around the shoulders of the collar becomes twisted, and wrinkles and folds cannot be eliminated.
[0007] The technique disclosed in Patent Document 1 requires sewing to prevent the collar stays from moving, which requires sewing skills, labor, and time.
[0008] The kimono in Patent Document 2 is made of a piece of fabric and a polymeric core, and because the collar side is made of a piece of fabric, it is difficult to spread between the collar and the outer collar, which takes time and effort, and wrinkles and folds do not disappear even when folded.
[0009] Here, the present invention aims to improve wrinkles and folds by allowing a collar stay to be easily inserted into the collar according to Patent Documents 1 and 2, without the need for sewing. [Means for solving the problem]
[0010] In order to solve this problem, the inventors have worked day and night to invent the following means. As a first measure, A long, thin plate-like object to be inserted into the collar of a Japanese kimono undergarment, A collar stay characterized in that a hole including a center line in the lateral direction of the plate-like object is provided. to provide.
[0011] As a second measure, The width value of the hole is 100 mm or more, and the length value of the hole is 3 mm or more. The collar core according to claim 1, characterized in that is provided.
[0012] As means 3, The collar core according to any one of means 1 or means 2, characterized in that it has a linear folding portion between the outer peripheral portion of the hole and the vertical outer peripheral edge of the collar core is provided.
[0013] By the way, the undergarment of a kimono can be any kind as long as it is an undergarment of a kimono with a collar. For example, there are long slips, two-piece slips, half-slips, false slips, false collars, etc.
[0014] The plate-like object is a so-called collar core, and at least a part of it is made of a hard material such as polyethylene, nylon, polypropylene, kozo paper, paper core, cloth core, etc.
[0015] The hole can be of any shape as long as it penetrates through from the front to the back. However, the optimal shape is not a circular shape or the like. For example, as shown in FIG. 1 or FIG. 2, a horizontally long hole is preferable. An end view example thereof is shown in the end view along line A - A' in FIG. 1.
[0016] The vertical outer peripheral edge refers to the outer peripheral edges on both vertical sides of the collar core as shown in FIG. 1. The horizontal outer peripheral edge refers to the outer peripheral edges on both horizontal sides of the collar core as shown in FIG. 1.
[0017] The center line is a virtual line that crosses the center in the horizontal direction of the collar core. More specifically, as shown in FIG. 1 or FIG. 3, it is a line showing the center between the vertical outer peripheral edges at both ends. Even more specifically, it is a line connecting two points, namely the center of the upper horizontal outer peripheral edge and the center of the lower horizontal outer peripheral edge of the collar core.
[0018] The width of the hole refers to the maximum value in the horizontal direction of the hole. The length of the hole refers to the maximum value in the vertical direction of the hole.
[0019] Incidentally, the outer peripheral part of the hole is the edge of the hole. More specifically, as shown in Fig. 2, it refers to the total part of the inner outer peripheral side and the front outer peripheral side of the hole. Incidentally, the hole refers to the total part of the outer peripheral part of the hole and the inside of the hole. Incidentally, the end part of the outer peripheral part of the hole is as shown in Fig. 1 or Fig. 2.
[0020] The vertical direction, the horizontal direction, and further up and down are as shown in Fig. 1.
[0021] The folding part can have any structure as long as the collar core folds at that part. For example, it is a laminate of paper and cloth with an adhesive. This time, it is a structure in which cardboard (thickness of about 0.5 mm) is used as the core material, and a so-called adhesive core is laminated on both sides thereof. An example of its end view is shown in the end view along line B - B' in Fig. 1.
Advantages of the Invention
[0022] This collar core is in contact with both sides of the collar, the collar edge is in contact with the front side, the inner side, and the fold of the collar, so it has the effect of looking neat and clean.
[0023] Since there is a hole, the front outer peripheral side of the hole can be made longer than the inner outer peripheral side of the hole, and the collar and the inner collar core are not wrinkled, and the collar is sandwiched in the hole and folded, so there is an effect that wrinkles and creases do not occur.
[0024] The inner side of the part around the collar shoulder descends along the body, the front side is displaced up and down so as to push up the fold, and when the collar core is inserted into the collar and folded, it becomes a stress in the vertical direction, so there is an effect that wrinkles and creases do not occur.
[0025] By making the folding part thinner than the front collar core and the inner collar core, it is easy to fold, and the collar core follows the front side, the inner side, and the fold of the collar, so there is an effect that there are no wrinkles and creases and it becomes neat and clean.
[0026] When using the collar core for the undergarment of a kimono, sewing work is required, and it takes sewing techniques, labor, and time, but there is an effect that sewing work is not necessary.
[0027] Since no sewing work is required, there is a gap inside when folded, and this gap serves as play, resulting in the effects of no wrinkles and no pleats.
[0028] Since it is a plate-like object, it can be easily inserted into the collar as a collar core, and it has the effect of being wearable just by folding.

Modes for Carrying Out the Invention
[0030] Hereinafter, an example of an embodiment of the present invention will be described. As shown in FIG. 1, it is a plan view of a typical collar core of the present invention, which is provided with a gentle slope from the center line toward the left and right, and is a collar core that contacts both the front side and the inner side of the collar.
[0031] The vertically downward one is the front side collar core, and the vertically upward one is the inner side collar core. There is a horizontally long hole including the center line between the front side collar core and the inner side collar core, and a linear folding portion is provided from the end of the outer peripheral portion of the hole to the vertical outer periphery.
[0032] The outer size is as shown in FIG. 3.
[0033] The hole is preferably a horizontally long hole as shown in Fig. 2. If the width of the hole is less than 100 mm, wrinkles and folds will appear inside the collar core. If the vertical width of the hole is less than 3 mm, wrinkles and folds will appear inside the collar core.
[0034] Preferably, the vertical width of the hole is 3 mm or more and the horizontal width is 100 mm or more.
[0035] As shown in Fig. 2, the outer peripheral side of the front surface of the hole is longer than the inner peripheral side of the hole, and if the difference is less than 2 mm, wrinkles and folds will appear.
[0036] By the way, the folded part is a material thinner than the front collar core and the inner collar core. As shown in Fig. 1, it is connected to the end of the outer peripheral part of the hole, and the other part is connected to the vertical outer peripheral side.
[0037] This part is the folded part, and for this reason, it has a certain width (gap). As the width of the folded part this time, the width of the end of the outer peripheral part of the hole is about 2 mm and the vertical outer peripheral side is 5 mm.
[0038] As shown in Figs. 5 and 6, the front collar core and the inner collar core are displaced in the vertical direction, and as shown in Fig. 5, there is a hole between the front collar core and the inner collar core.
[0039] As shown in Fig. 7, because there is a hole, the collar is sandwiched between the front collar core and the inner collar core, and the collar core is folded inside the collar, that is, between the collar and the outer collar, and wrinkles and folds do not appear due to the vertical stress.
[0040] As the material of this collar core, paper material, plastic material, cloth material, composite materials thereof, and furthermore, any material such as laminating these materials can be used. The material used this time is a laminate of paper and cloth with an adhesive.
[0041] Specifically, two pieces of cardboard (thickness about 0.5 mm) cut to a predetermined size and a so-called adhesive core sold on the market were adhered one by one with an iron and laminated on both sides.
[0042] The laminating conditions at that time were set at 200 degrees with a household iron, with a pressing cloth applied and pressure applied for about 5 seconds.
[0043] Finally, the remaining vertical outer periphery, horizontal outer periphery, and the inside of the hole were cut off along the outer periphery of the hole with scissors as shown in Figure 1.
[0044] This collar core has the effect that by narrowing the collar width along the shoulders and neck, the collar is less likely to stand up when worn, it fits neatly and smoothly, and there is less burden on the body.
[0045] When wearing the undergarment of a kimono, it is easier for the collar to fall forward around the collar shoulders. However, since the collar core inside the collar shoulders falls along the body, it has the characteristic of being less likely to become loose.
[0046] The part around the collar shoulders is in a rounded U shape, making it easy to follow the body.
[0047] By changing the shape, width of the joint, material, etc. of this collar core, it can be made to correspond to the entire kimono and bridal clothing.
[0048] This collar core is selected from excellent materials and fabrics such as flexibility, elasticity, shape memory, and breathability.
[0049] Each embodiment disclosed in this specification is illustrated for the purpose of facilitating the understanding of the collar core according to the present invention, and the present invention is not limited thereto. That is to say, it goes without saying that the present invention can be appropriately designed and changed in the production of the collar core as long as it does not deviate from the scope of the claims.
