Title: Trousers with a crotch closure/opening structure

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to trousers and, more particularly, to trousers with a crotch closure/opening structure. 
     Trousers are a general term for clothing worn on two legs below the waist of a human body. Trousers include long trousers and short trousers according to the length, include men&#39;s trousers and women&#39;s trousers according to design, and include sports trousers, sleeping trousers, and underwear trousers according to use. 
     Trousers can include an elastic waistband to permit easy wearing and taking off. For trousers (such as jeans and dress pants) without the elastic waistband or lack of flexibility, a zipper is provided on a front side of the trousers, such that a male user can simply open the zipper for urination without taking off the trousers. However, since the length of the zipper merely extends along the front side and due to the female physical structure, a female wearing trousers has to pull down the trousers to her thighs when using a toilet. 
       FIG. 4  shows a urinal  2  disclosed in U.S. Ser. No. 14/940,332 filed Nov. 13, 2015 (Taiwan Utility Model No. M493963) filed by Applicant. A female user can use the urinal  2  in a standing or semi-squatting position. However, a female user wearing trousers still has to pull down her trousers to her thighs, which is still inconvenient to the female user whose trousers are on the thighs while she is standing or semi-squatting for urination. 
     Thus, a need exists for novel trousers permitting female wearers to conveniently use a toilet in a standing, squatting, or semi-squatting position. 
     BRIEF SUMMARY OF THE INVENTION 
     Trousers with a crotch closure/opening structure according to the present invention includes a trouser body having a front side and a rear side. A zipper is mounted to the front side of the trouser body. The zipper extends downwards from a top end of the front side of the trouser body, extends rearwards through a crotch of the trouser body, and extends upwards to a location of the rear side corresponding to hips of a human body. 
     The zipper extending from the top end of the front side through the hip portion permits a female wearer using a toilet to open the front side, the crotch, and the rear side of the trouser body by simply opening the zipper without taking off the trousers. The trousers according to the present invention also permits a female wearer to use a standing urinal or a squatting urinal.
