Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is related to a cap structure with
reduced length of stretchable material in sweatband, and especially
to such a cap structure that can allow changing the size measuring
around the entire sweatband and of the crown of the cap. In a
conventional stretchable cap structure, expensive stretchable
material is used for entire sweatband, however, due to the rigidity
of the peak, the portion of stretchable material of the sweatband
which is adjacent to the peak portion cannot present its original
intended function stretchability. Therefore in the present
invention by providing the partially stretchable two-segment
sweatband which not only can effectively reduce the wasting
stretchable material in the sweatband to thereby reduce the cost of
production of the cap but also can get the maximum covering effect
of the stretchable cap. The structure especially suits the
structures of various caps or the like.
[0003] 2. Description of the Prior Art
[0004] Styles of caps are various; in addition to the functions of
sun shading and keeping warm, they can provide the function of
decoration. Conventionally, there are two types of caps: fixed-size
caps and adjustable caps, while there are two kinds of fixed size
cap: single-size caps and stretchable caps. A single-size cap is
non-adjustable which can only suit a very narrow rang of head
sizes, and cap manufacturers have to produce a lot of different
sizes of cap to satisfy wearer's demand, this may increase the cost
of production. A conventional stretchable cap can suit a much wider
range of head sizes than a single-size cap by having the combined
panels of each crown connected with an elastic sweatband; the crown
of each cap is stretched by the elastic sweatband for changing the
size measuring around the entire sweatband and of the crown of the
cap to suit various head sizes.
[0005] However, the above stated structures mostly use non-elastic
material at the front part of the crown of each cap for the
functions of sun shading and keeping rain away; while the elastic
sweatband is more expensive for production, it will increase the
cost of production and will be wasteful when it is used at the area
where the front part of the crown is made of non-elastic
material.
[0006] While the adjustable caps use an adjustable-length closure
at the bottom of the open area which is disposed at the rear of the
cap to adjust the sizes; however, such type can only allow
adjustment at the rear open area of the crown, the cap thereby is
subjected to bunching up on the rear panels, hence impairs its
aesthetic appearance.
[0007] In view of this, the inventor of the present invention
develops the cap structure with reduced length of stretchable
material in sweatband that can allow changing the size measuring
around the entire sweatband and of the crown of the cap and can
reduce the cost of production.
SUMMARY OF THE INVENTION
[0008] The primary object of the present invention is to provide a
cap structure with reduced length of stretchable material in
sweatband, wherein by providing a two-segment sweatband and a
plurality of stretchable elastic gores, the size measuring around
the entire sweatband and of the crown of the cap can be changed to
get the maximum covering effect of the stretchable cap.
[0009] Another object of the present invention is to provide a cap
structure with reduced length of stretchable material in sweatband,
wherein by providing a two-segment sweatband comprising a
non-stretchable sweatband portion of lower cost sewn at the area
where the lower peripheral edge on the inside of the crown which is
corresponding the peak position of the cap, thus, the cost of
production can be effectively reduced to avoid functional waste of
the stretchable material at the non-stretchable area corresponding
to the peak area.
[0010] To get the above stated objects, the crown of the present
invention has a plurality of stretchable gores butt-connected
mutually to form a semi-spherical shape; the crown is provided by
sewing on the front side thereof with a peak panel; a
non-stretchable sweatband portion is sewn at the area where the
peak panel is corresponding to the crown. The other portions at the
lower peripheral edge on the inside of the crown except the area
where the non-stretchable sweatband portion locates are connected
by sewing with the stretchable sweatband portion to form the cap
structure with reduced length of stretchable material in sweatband.
By providing the two-segment sweatband and the plurality of
stretchable gores the size measuring around the entire sweatband
and of the crown of the cap can be changed to get the maximum
covering effect of the stretchable cap. And by providing the
non-stretchable sweatband portion, the cost of production can be
effectively reduced to avoid functional waste of the stretchable
material for the non-stretchable peak area.
[0011] 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
[0016] Referring firstly to FIGS. 1, 2, the cap structure with
reduced length of stretchable material in sweatband of the present
invention is comprised of a plurality of stretchable gores 11, a
peak 20, a stretchable sweatband portion 31 and a non-stretchable
sweatband portion 40.
[0017] Wherein, the stretchable gores 11 are each in the shape of a
triangle sheet made by stretchable fabric, and can be uniformly
stretched when in bearing an external pulling force.
[0018] The peak 20 is a curved board in order that the cap can
shade the sunshine and rain.
[0019] The stretchable sweatband portion 31 is a strip made of
stretchable material to be elastically stretched. The
non-stretchable sweatband portion 40 is also a strip.
[0020] Referring firstly to FIG. 1, when the present invention is
assembled, the stretchable gores 11 are butt-connected mutually to
form a hollow semi-spherical crown 10; the crown 10 is provided by
sewing on the front side thereof with the peak 20; the
non-stretchable sweatband portion 40 is sewn at the area where the
peak 20 corresponding to the lower peripheral edge of the inner
side of the crown 10. The other portions at the lower peripheral
edge of the inner side of the crown 10 except the area where the
non-stretchable sweatband portion 40 locates are interconnected by
sewing with the stretchable sweatband portion 31 to form an entire
circle of sweatband 30. By combination of the above members, the
cap structure with reduced length of stretchable material in
sweatband is completed.
[0021] Referring to FIGS. 3a and 3b, when the present invention is
worn on a head, by contact of the head with the crown 10, the crown
10 bears an expanding pulling force, the stretchable gores 11 can
be uniformly stretched by their own elasticity, the stretchable
sweatband portion 31 is also uniformly stretched to elongate.
Thereby, the size of the entire circle of sweatband 30 can be
effectively changed to suit wearers of different head sizes; the
shape and size of the crown 10 can also be changed in pursuance of
different head sizes to get the maximum covering effect of the
stretchable cap.
[0022] Referring to FIG. 3a, as to the connecting area of the crown
10 with the peak 20, the stretchable gores 11 and the peak 20 are
sewn together, hence the elasticity of the stretchable gores 11 is
restrained by the peak 20 from making the entire circle of
sweatband 30 stretch elastically; while the non-stretchable
sweatband portion 40 sewn at the lower peripheral edge of the inner
side of the crown 10 is not stretchable, thereby its cost is lower
than that of the elastically stretchable sweatband portion 31 and
can effectively reduce the cost of production and avoid functional
waste of the stretchable material for at the area corresponding to
the peak board.
[0023] The present invention thereby has the following
advantages:
[0024] 1. By providing the two-segment sweatband and the
stretchable gores, the size measuring around the entire sweatband
and of the crown of the cap of the present invention can be changed
to get the maximum covering effect of the stretchable cap, the
practicality of the cap therefore can be increased.
[0025] 2. By providing the non-stretchable sweatband portion of
lower cost sewn at the area of the lower peripheral edge of the
front side of the crown is corresponding to the peak of the cap,
the cost of production can be effectively reduced to avoid
functional waste of the stretchable material for the
non-stretchable peak area. And the present invention can be of
industrial value.
[0026] In conclusion, not only the present invention can get rid of
the defect of conventional cap structures, but also the size
measuring around the entire sweatband and of the crown of the cap
of the present invention can be changed to get the maximum covering
effect of the elastic cap by providing the two-segment sweatband
and the stretchable gores. Further, the non-stretchable sweatband
portion can effectively reduce the cost of production and avoid
functional waste of the stretchable material for the
non-stretchable peak area. And the practicality as well as
convenience of the cap can be increased. The present invention
suits various cap structures and thereby is industrial
valuable.
[0027] The stretchable cap structure forming by the elements stated
above is only for illustrating a preferred embodiment of the
present invention, and not for giving any limitation to the scope
of the present invention. It will be apparent to those skilled in
this art that various modifications or changes made without
departing from the spirit of this invention shall fall within the
scope of the appended claims of this invention.
