Title: Cap structure capable of elastic adjusting

Description:
BACKGROUND OF THE INVENTION 
     The present invention is related to a structure of cap capable of elastic ajusting the cap; and especially to such a cap with two elastic bands on the inner sides of the middle panels of the crown in order that the size of the cap can be adjusted to suit different users. The cap thereby can have the feature of unity of size by which manufacturing cost can be reduced. 
     Since caps of good quality and being convenient to wear were widely used, modes of wearing caps have been being thought highly by users, and caps of various fashions and types have been produced accordingly. 
     However, most conventional caps are divided into two kinds, i.e., the type of unitary size and the type of variable size. The former type needs making a lot of caps of different sizes for various head sizes, thus the manufacturing cost thereof can be increased. The later type generally is provided on a cap only with an adjustment snap locker or an elastic binding cord to increase the scope of application of a cap; such design can only have an opening at the rear of the cap adjusted, this renders the rear panels of the cap to be subjected to tucking to result an ugly appearance, and it can only be adjusted to suit a specific scope of head size, if the adjustment snap locker is overly or insufficiently adjusted, it can both influence esthetic view of appearance. Thereby, a prior art (as shown in FIGS.  4  and  4 - 1 ) has a crown  5  which is sewn with a visor  4 , a plurality of elastic members  51  are provided to extend from the central top to the bottom edge of the crown  5 . By providing these elastic members  51 , the crown  5  can have a plurality of elastically adjustable areas for elastically adjusting the size of the crown  5  to suit various head sizes of users. However, the amount of the elastic members  51  required is quite large, it is expected thereby that manufacturing cost is increased. 
     SUMMARY OF THE INVENTION 
     The primary object of the present invention is to provide a structure of cap capable of elastic adjusting the cap, two elastic bands are provided and sewn alternately with two sweatbands to give the function of elastic adjustment, the two elastic bands are respectively sewn on two elastic middle panels of the crown of the cap, so that a larger area which can allow adjustment of the size of the crown can be provided to suit various head sizes and shapes of different users, thereby practicality can be increased. 
     Another object of the present invention is to provide a structure of cap capable of elastic adjusting the cap, two elastic bands and two sweatbands are provided and are alternately sewn together to give an effect of elastic adjustment of the size of the crown without tucking, thereby manufacturing cost can be reduced. 
     To get the above stated objects, the present invention is provided on the inner side of the bottom edge of the crown with two elastic bands and two sweatbands alternately sewn together to form a tape; the two elastic bands are respectively sewn on two elastic middle panels of the crown of the cap to allow adjustment of the size of the crown to suit various head sizes and shapes of different users, thereby an effect of elastically adjusting the crown can be obtained, manufacturing cost can be reduced and practicality can be increased. 
     The present invention will be apparent in its particular structure and characteristics after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring firstly to FIG. 1,  2  and  3 , the structure of cap capable of elastic adjusting the cap of the present invention is comprised of the elements including a visor  1 , a crown  2  and a tape member  3  etc. 
     The visor  1  is sewn together with the crown  2  which is formed by sewing together two front panels  21 , two elastic middle panels  21 A and two rear panels  21 B. The inner side  22  of the bottom edge of the crown  2  is provided with the tape member  3  which is formed by sewing together two elastic bands  31  alternately with two sweatbands  32 . The two elastic bands  31  are respectively sewn on the two elastic middle panels  21 A. 
     By providing the abovementioned members, the elastic bands  31  and the two sweatbands  32  of the tape member  3  are sewn alternately mutually to form the structure of cap capable of elastic adjusting the cap. Referring to FIG. 2 and 3, the present invention is characterized by that, the tape member  3  is formed by sewing together the two elastic bands  31  alternately with the two sweatbands  32 . The two elastic bands  31  are respectively sewn on the two elastic middle panels  21 A, by the elasticity of the elastic bands  31  and the two elastic middle panels  21 A, the size of the tape member  3  can be adjusted to suit various head sizes and shapes of different users. Thereby an effect of elastically adjusting the crown can be obtained, practicality of the cap can be increased, and the structure of cap capable of elastic adjusting the cap is completed. 
     Referring again to FIG. 1,  2  and  3 , the tape member  3  is formed by sewing together the two elastic bands  31  alternately with the two sweatbands  32  as stated above, then the tape member  3  is sewn onto the inner side  22  of the bottom edge of the crown  2  and the two elastic bands  31  are respectively sewn on the two elastic middle panels  21 A, thereby, elastic adjustment function of the tape member  3  renders elastic adjusting of the crown probable. And by the two elastic middle panels  21 A, the cap can suit a larger scope of application for various head sizes without tucking, and esthetic view of appearance of the cap can be obtained. 
     Accordingly, it only needs to sew the visor with the crown of the cap, and to sew a tape member onto the inner side of the bottom edge of the crown (the tape member is formed by sewing together two elastic bands (such as elastic yams, elastic woven bands etc.)) alternately with two sweatbands. The two elastic bands are respectively sewn on the two elastic middle panels of the crown, so that an effect of elastically adjusting the crown can be obtained, and practicality of the cap can be increased. 
     The present invention has the following advantages: 
     1. The present invention has a tape member having the function of elastic adjustment to adjust the size of the crown of a cap to suit various head sizes and shapes of different users, thereby, practicality of the cap can be increased. 
     2. The function of elastic adjustment of the tape member of the present invention is effected with two elastic bands provided and sewn alternately with two sweatbands, thereby amount of the elastic bands can be reduced for obtaining the elastic adjustment effect of adjusting the size of the crown, and thereby cost of manufacturing and production can be lowered. 
     3. In the present invention, the two elastic bands are respectively sewn on two elastic middle panels of the crown of the cap, the two elastic bands and the two elastic middle panels allow adjustment of the size of the crown without tucking. 
     In conclusion, the present invention not only can get rid of the defect of conventional caps, but also is provided on the inner side of the bottom edge of the crown with two elastic bands and two sweatbands alternately sewn together to form a tape; the two elastic bands are respectively sewn on two elastic middle panels of the crown of the cap to allow adjustment of the size of the crown to suit various head sizes and shapes of different users; thereby an effect of elastically adjusting the crown can be obtained, manufacturing cost can thus be reduced and practicality can be increased. The present invention can suit various types of caps; it is no doubt in having the value of practicality.
