Description

Technical Field

[0001] The present invention relates to a T-shirt having an upward collar at the rear half of the collar part.

Background Art

[0002] T-shirts are staple fashion items that are indispensable for a casual style, being worn as is without an outer garment in summer or used for layering. In recent years, as awareness of the environment has increased, the number of companies adopting cool biz as an energy-saving measure has grown, and the opportunity to layer a T-shirt instead of a dress shirt with an outer garment such as a jacket has become more common in the workplace and informal settings. In such cases, the opportunity to sweat increases at the workplace or when out, and there is a growing need to eliminate stickiness and sweat stains around the neck of the outer garment.

[0003] In conventional shirts such as T-shirts, a tape fabric is sewn around the neck to form the collar part. Also, in conventional general shirts such as T-shirts, the collar part is not particularly formed, and the neckline of the shirt directly contacts the wearer's neck. On the other hand, in dress shirts and polo shirts that form collars, unlike T-shirts, the collar part is likely to be damaged and soiled because it directly contacts the neck, so efforts are made in the shape and height of the collar part to avoid direct contact with the wearer's neck muscles as much as possible, and for example, a shirt with the structure proposed in Patent Document 1 is known.

[0004] The shirt disclosed in this Patent Document 1 forms a neckline part by a front collar groove part at the upper end of the front body and a rear collar groove part at the upper end of the back body, and forms the front collar groove part and the rear collar groove part around the entire circumference of the neckline part and overlaps them to sew and form the collar part. In this way, the front collar part sewn to the front collar groove part and the rear collar part sewn to the rear collar groove part are composed of one fabric, and the height of the rear collar part is characterized by being higher than the height of the front collar part.

[0005] Furthermore, by making the height of the back collar part lower than the height of the collar part of outerwear such as a jacket worn over the shirt, it becomes less visible as it is hidden under the collar of the jacket, maintaining an aesthetic appearance without any problems, and preventing the back collar part of the shirt from being exposed from the collar part of the outer clothing.

[0006] In this way, the back collar part of the shirt abuts against the rear part of the wearer's neck, directly touches the wearer's neck muscles, and can prevent collar stains on the outer clothing.

Summary of the Invention

Problems to be Solved by the Invention

[0008] However, in the shirt disclosed in Patent Document 1, the front collar part sewn to the front collar groove part and the back collar part sewn to the back collar groove part are made of a single piece of fabric, and it is easy for the fabric to stretch and lose its shape due to pulling of the fabric around the neck during attachment / detachment and washing.

[0009] Also, in the shirt disclosed in Patent Document 1, the height of the back collar part is lower than the collar part of the outerwear worn over the shirt. Therefore, when wearing a T-shirt instead of an outer garment (e.g., a dress shirt), it cannot prevent collar stains on outerwear such as jackets.

Means for Solving the Problems

[0010] Therefore, in order to solve the main problems of the present invention, a shirt body is formed by the front body, the back body, and the left and right sleeve parts. A neck part is formed at the top of the front and back bodies, and a collar part is formed on the front half and the back half of the neck part. The lower edge of the front half of the collar part is sewn along the peripheral edge of the front half of the neck part, and the lower edge of the back half of the collar part is sewn along the peripheral edge of the back half of the neck part. The width of the back half of the collar part is formed longer than that of the front half. Moreover, the left and right ends of the front half of the collar part and the left and right ends of the back half of the collar part are formed in a gradually tapering shape at the tip and overlap and are sewn to the peripheral edge around the neck, so as to be formed to rise above the collar height of the back half of the collar part with a long width when worn. The present invention provides a shirt characterized by this.

Effect of the Invention

[0011] According to the present invention, a shirt body is formed by the front body, the back body, and the left and right sleeve parts. A neck part is formed at the top of the front and back bodies, and a collar part is formed on the front half and the back half of the neck part. The lower edge of the front half of the collar part is sewn along the peripheral edge of the front half of the neck part. The lower edge of the back half of the collar part is sewn along the peripheral edge of the back half of the neck part. The width of the back half of the collar part is longer than that of the front half. Moreover, the left and right ends of the front half of the collar part and the left and right ends of the back half of the collar part are formed in a gradually tapering shape at the tip and overlap and are sewn to the peripheral edge around the neck, so that it is possible to obtain clothing with a high wearing feeling that fits well with the shape of the human body, especially the shape around the neck, and excellent design. At the same time, the width of the back half of the collar part is longer than that of the front half. Moreover, the left and right ends of the front half of the collar part and the left and right ends of the back half of the collar part are formed in a gradually tapering shape at the tip and overlap and are sewn to the peripheral edge around the neck. Since the width of the back half of the collar part is long and is formed in a gradually tapering shape at the tip and overlaps and is sewn to the peripheral edge around the neck, the lower edge part of the width of the back half of the collar part is thickened and reinforced by the left and right ends of the front half of the collar part, so the strength is increased and it is likely to form a stand-up collar shape.

[0012] Therefore, when the rear half of the collar contacts the back of the wearer's neck, the left and right ends of the front half of the collar and the left and right ends of the rear half of the collar due to the width of the front half adsorb sebum stains that were conventionally attached to the collar of an upper garment such as a jacket, and it is possible to prevent the collar of the upper garment from getting dirty, reduce the burden of washing and dry cleaning, and make the upper garment last longer. In this way, the rear half of the collar can exhibit an antifouling function.

Modes for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the shirt according to the present invention. In the figure, the shirt 1 according to the present invention has a front body 2, a back body 3, and sleeve parts 4, 4, and a neck area 8 is formed by a front collar groove part 9 which is a part of the upper end of the front body 2 and a rear collar groove part 10 which is a part of the upper end of the back body 3. The front body 2, the back body 3, and the sleeve parts 4 can be made of any material used for conventional shirts, and typically, they can be made of a cotton fabric such as Supima cotton. By using a material with a good texture, the wearing comfort can be improved, but it is not particularly limited. For example, the material may be 100% cotton, or a blended fabric with hemp, polyester, polyurethane, etc., and it becomes possible to further enhance the cold resistance and moisture absorption.

[0015] FIG. 2 is a developed view showing a fabric piece forming the collar portion of the shirt according to the present invention. The rear half and the front half of the collar portion are configured separately. The rear half 7 of the collar is sewn to the neckline of the back body portion with a substantially straight side, and the front half 6 of the collar is sewn to the neckline of the substantially concave side of the front body portion (see FIG. 3). The front collar and the rear collar portions are bilaterally symmetrical in shape. In the collar portion, A-A and B-B shown by broken lines are folded back to form the collar end lines 6c and 7c (see FIG. 2).

[0016] As shown in FIG. 4, a part of the front half 6 of the collar and a part of the rear half 7 of the collar, which are folded in two, are overlapped and sewn over the entire circumference to the front collar groove portion 9 of the front body 2 and the rear collar groove portion 10 of the back body 3 that form the neck circumference portion 8.

[0017] Thus, in the present invention, the rear half 7 of the collar is provided separately from the front half 6 of the collar at the rear portion of the neck circumference portion 8. The rear half 7 of the collar is attached so as to overlap a part of the front half 6 of the collar from the rear collar groove portion 10 to a part of the front collar groove portion 9.

[0018] And, the maximum height dimension of the rear half 7 of the collar is larger than that of the front half 6 of the collar and protrudes upward from the front half 6 of the collar at the rear collar groove portion 10, and the height dimension thereof gradually decreases at the front collar groove portion 9. The height dimension 6d of the front half 6 of the collar is preferably about 1.0 to 4.0 cm in the sewn state, and the maximum height dimension 7d of the rear half 7 of the collar is preferably about 2.0 to 5.0 cm, and preferably about 1.2 to 2 times that of the front half 6 of the collar.

[0019] As shown in the development view of Fig. 2, the front half 6 and the rear half 7 of the collar each have a central portion 6a, 7a attached to the front collar groove portion 9 and the rear collar groove portion 10, respectively, and end portions 6b, 7b on both sides sandwiching the central portions 6a, 7a and attached to the front collar groove portion 9 in an overlapping manner. The central portions 6a, 7a bulge in the vertical direction, and the contours of the central portions 6a, 7a match the contours of the front collar groove portion 9 and the rear collar groove portion 10. When the front half 6 and the rear half 7 of the collar are attached to the front collar groove portion 9 and the rear collar groove portion 10, respectively, the height dimension is set to be substantially constant. The end portions 6b, 7b gradually decrease in vertical dimension toward the ends of the front half 6 and the rear half 7 of the collar.

[0020] The front half 6 and the rear half 7 of the collar are double-folded at the collar end lines 6c, 7c (in Figs. 2(b) and (d), with the collar end lines 6c, 7c as the upper sides) and sewn to the rear collar groove portion 10 and the front collar groove portion 9.

[0021] And as shown in Fig. 2, the central portion 7a of the rear half 7 of the collar is preferably sewn and joined to the rear collar groove portion 10 together with the tucking tape 13 provided inside thereof. The tucking tape 13 is folded into three at C-C and C'-C' shown by broken lines (in Figs. 2(e) and (f)), and extends from the rear collar groove portion 10 and is sewn to the stitching portion of the shoulder portion 15 at the upper end of the back body 3 so that the fold lines 13c, 13c are the upper and lower sides. By providing the tucking tape 13 extending toward both shoulder portions, the portion provided on the rear collar groove portion 10 of the rear collar portion can be supported, and it can be made to stand up easily.

[0022] Also, the end portions 7b, 7b of the rear half 7 of the collar are sewn to the front collar groove portion 9 in an overlapping manner with the end portions 6b, 6b of the front half 6 of the collar, away from the tucking tape 13. The ends of the rear half 7 of the collar are positioned at the ends of the front collar groove portion 9 of the front body 2, and in the unworn state of the front view shown in Fig. 4, the end portions 7b, 7b of the rear half 7 of the collar are folded back and sewn to the central portion 7a.

[0023] As shown in FIGS. 3 and 4, the ends 7b, 7b of the rear half 7 of the collar overlap with the front half 6 of the collar to form a thickness, thereby preventing the flexible drooping phenomenon of the rear half 7 of the collar made of a single cloth and making it easier to stand up when worn. In the above-mentioned shirt 1, when worn, the thick portion where the rear half 7 of the collar overlaps with the front half 6 of the collar abuts against the wearer's neck, so the rear half of the collar with a width longer than that of the front half of the collar stands up along the neck.

[0024] In the shirt 1 provided with the front half 6 and the rear half 7 of the collar configured as described above, when worn, the rear half 7 of the collar abuts against the rear part of the wearer's neck. Although the height dimension of the rear half 7 of the collar is high at the rear collar fitting part 10, it only exists at the rear part of the front collar fitting part 9 in the front collar fitting part 9. Therefore, when another piece of clothing, for example, an upper garment 14 as shown in FIG. 5, is worn over the shirt 1, the collar of the shirt 1 does not get in the way and does not deteriorate the aesthetics.

[0025] And in the shirt 1 configured in this way, since the width of the rear half 7 of the collar is formed longer than the width of the front half 6 of the collar and is configured to stand up along the neck, it can be made into a clothing with a high wearing feeling that fits well with the shape of the human body, especially the shape near the neck, and excellent design.

[0026] Also, when the rear half 7 of the collar hits the rear part of the wearer's neck, the rear half 7 of the collar adsorbs the sebum stains that were conventionally attached to the collar of the upper garment such as a jacket, etc., and can prevent the collar of the upper garment 14 from getting dirty, reducing the burden of washing and dry cleaning, and making the upper garment 14 last longer. In this way, the rear half 7 of the collar can exhibit an antifouling function.

[0027] In addition, in the above embodiment, the description was made on the premise of a shirt worn together with an upper garment as a shirt, but it is not limited to this, and it is also possible to find a design in the peculiarity of the rear collar according to the preference of the wearer and wear it alone as a shirt.

[0028] In the shirt 1 shown in FIG. 1, the sleeve part 4 is exemplified as a short sleeve, but it may be a long sleeve, or there may be no sleeve part.

[0029] In addition, in the above embodiments, a round-neck type shirt has been exemplified, but the present invention is not limited thereto, and the present invention can be similarly applied to any shirt of a V-neck type or any other arbitrary shape.
