BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a brassiere pad adjustable structure for a brassiere.
Descriptions of the Related Art
[0002] Brassieres contain brassiere pads which are disposed on the inside of cups of the
brassiere to prevent sagging and non-uniform breast sizes. When a woman wears the
brassiere, her breasts are covered by the cups so that the brassiere pads are located
between the breasts and the cups to adjust the shape of the woman breasts.
[0003] FIG. 1A illustrates a schematic cross-sectional view of a conventional brassiere pad adjustable
structure
1. To adjust the shape of the breasts in response to the demands of different users,
the brassiere pad adjustable structure 1 has an air pump
1a, two air cells
1b and two passages
1d. The air pump
1a is connected with each of the air cells
1b through a respective passage
1d. When the air pump
1a is pressed, the air pump
1a is adapted to provide air to each of the air cells
1b so that the air cells
1b are expanded to adjust the sizes of the air cells
1b in response to the user's demand.
FIG. 1B illustrates the brassiere pad adjustable structure 1 that is disposed on the inner
surface of a brassiere. The brassiere includes two cups
1e, and each of the air cells
1b is disposed in the respective cup
1e. FIG. 1C is a schematic view illustrating the relative positional relationship between the
cups
1e and the air cells
1b of the brassiere. The bottom edge
1e of each of the air cells
1b is connected with the bottom edge
1f of the respective cup
1e so that the brassiere pad adjustable structure 1 can be connected with the brassiere.
[0004] According to the above descriptions, the inclination angle of the air cells
1b is limited when the bottom edge
1c of each of the air cells
1b is connected with the bottom edge
1f of the respective cup
1e. Consequently, when the air cells
1b are expanded, the air cells
1b will move away from the cups
1e to incline at an angle as shown in
FIG. 1C. The air cells
1b are unable to completely attach to the cups
1e because of the spaces existing therebetween. As a result, when the user wears the
brassiere, her breasts are not completely flush with the cups
1e and the air cells
1b. Furthermore, when the conventional brassiere pad adjustable structure 1 is joined
with the brassiere, the air pump
1a is correspondingly disposed in a brassiere central region
1g between the cups
1e. To prevent the air pump
1a from being exposed, the brassiere central region
1g must be made to have a certain height, so this makes the conventional brassiere pad
adjustable structure 1 unsuitable for brassieres with a relatively lower height in
the central region. In other words, the conventional brassiere pad adjustable structure
1 is only suitable for brassieres with a shallow V-shaped brassiere central region
(as shown in
FIG. 1B), but it is unsuitable for other brassieres with a deep V-shaped brassiere central
region.
[0005] Accordingly, it is important to provide a brassiere pad adjustable structure to improve
the aforesaid drawbacks.
SUMMARY OF THE INVENTION
[0006] An objective of the present invention is to provide a brassiere pad adjustable structure
which can be used in various kinds of brassieres.
[0007] To achieve the aforesaid objective, a brassiere pad adjustable structure for use
in a brassiere is provided in an embodiment of the present invention. The brassiere
has two cups to correspond to two breasts of a human body respectively. Each of the
two cups has a concave portion and an inside bottom edge. The brassiere pad adjustable
structure comprises a pouch, an air pump and an exhaust valve. The pouch is formed
by a first layer film and a second layer film that is connected to each other to form
a one-piece structure. The pouch has two breast contacting portions and a central
passage portion. The central passage portion is located between the breast contacting
portions. The bottom edge of each of the breast contacting portions is connected with
an inside bottom edge of each of the cups. Each of the breast contacting portions
has a first top stitching that welds the first layer film and the second layer film
to divide each of the breast contacting portions into a first portion and a second
portion. The first portion is located between the bottom edge and the first top stitching
of each breast contacting portion, while the second portion corresponds to the concave
portion of each cup. At least one first passage disposed between the first portion
and the second portion passes through the first top stitching so that the first portion
and the second portion are in fluid communication with each other through the first
passage. The air pump is disposed on the pouch, and disposed on either the first layer
film or the second layer film. When the air pump is pressed, the air pump pumps fluid
into the pouch. The exhaust valve is disposed on the pouch and fixed on either the
first layer film or the second layer film to exhaust the fluids to the exterior. When
the air pump pumps fluids into the pouch, the pouch is expanded for forming an air
chamber.
[0008] The detailed technology and preferred embodiments implemented for the subject invention

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] FIG. 2A is a schematic view of a brassiere pad adjustable structure
2 of a first embodiment of the present invention.
FIG. 2B is a partial schematic cross-sectional view of
FIG. 2A. FIG. 2C is a schematic view illustrating the relative relationship between the brassiere
pad adjustable structure
2, a brassiere
3 and a breast
4 according to the first embodiment of the present invention.
FIG. 2D is a schematic view of the brassiere pad adjustable structure
2 connected with the brassiere
3 according to this embodiment.
[0011] The brassiere pad adjustable structure
2 of this embodiment may correspond to two breasts
4 of a human body. In detail, the brassiere pad adjustable structure 2 comprises a
pouch
21, an air pump
22 and an exhaust valve
23. The pouch
21 is formed by a first layer film
24 and a second layer film
25 that is connected to each other to form a one-piece structure. The pouch
21 has two breast contacting portions
211 and a central passage portion
212. The central passage portion
212 is located between the breast contacting portions
211. The breast contacting portions
211 and the central passage portion
212 are in fluid communication with each other.
[0012] With reference to both
FIGs. 2B and
2C, the brassiere pad adjustable structure
2 of this embodiment may be connected with a brassiere
3 so that when the user wears the brassiere
3, the brassiere pad adjustable structure
2 can correspond to the breast
4 of a human body. In detail, the air pump
22 is disposed on the pouch
21 and on either the first layer film
24 or the second layer film
25. Furthermore, the air pump
22 is disposed inside the pouch
21 and on either the first layer film
24 or the second layer film
25. When the air pump
22 is pressed, the air pump
22 is adapted to pump fluids into the pouch
21. An exhaust valve
23 is fixed on the pouch
21,. The user can press the exhaust valve
23 and the pouch
21 simultaneously at any time to exhaust the fluids in the pouch
21 to the exterior through the exhaust valve
23. Because the air pump
22 is disposed in the pouch
21 and can be disposed at any location of the pouch
21, it is not pertinent to locate the air pump
22 at the center of the brassiere
3. Thus, the brassiere pad adjustable structure
2 of this embodiment is suitable for various kinds of brassieres, e.g., the brassiere
3 with a deep V-shaped central region as shown in
FIG. 2D (i.e., the brassiere
3 with a relatively lower height in the central region). The air pump
22 is disposed in one of the breast contacting portions
211 to prevent the air pump
22 from being exposed.
[0013] With reference to
FIG. 2C, in practical application of this embodiment, the pouch
21 has a bottom edge
211a and the brassiere
3 has two cups
31. Each of the cups
31 has an inside bottom edge
31a and a concave portion
31b. The bottom edge
211a of the pouch
21 is connected with the inside bottom edge
31a of one of the cups
31. In this embodiment, the bottom edge
211a of the pouch
21 may be connected with the inside bottom edge
31a of each of the cups
31 by stitching. Steel wire coils may be disposed at the inside bottom edge
31a of each of the cups
31 in this embodiment; but in other embodiments of the present invention, the connection
may also be achieved by other means, for example, by adherence, and will not be further
described herein. When the two breasts of the user are of different sizes, the user
only needs to purchase the brassiere pad adjustable structure
2, dispose it in the cups of the brassiere
3 and adjust the size of the pouch
21 through the air pump
22 and the exhaust valve
23.
[0014] Additionally in this embodiment, as shown in
FIG. 2A, the exhaust valve
23 is disposed on the first layer film
24 away from the air pump
22 and is located on the central passage portion
212. However, in other embodiments, the exhaust valve
23 may also be optionally disposed on either the first layer film
24, or the second layer film
25 away from the air pump
22, or may be disposed in the air pump
22.
[0015] In this embodiment, the brassiere pad adjustable structure
2 can be bent to conform to the shape of the cups
31 and the breasts of a human body by a plurality of top stitchings. Each of the breast
contacting portions
211 has a first top stitching
26 that welds the first layer film
24 and the second layer film
25 to divide each of the breast contacting portions
211 into a first portion
21a and a second portion
21b. The first portion
21a is located between the bottom edge
211a and the first top stitching
26 of each breast contacting portion
211. Because the brassiere pad adjustable structure
2 is connected with the brassiere
3 and a steel wire coil may be disposed at the inside bottom edge
31a of each of the cups
31, the first portion
21a is also located between the inner edge of the steel wire coil and the first top stitching
26. The second portion
21b may correspond to the concave portion
31b of each of the cups
31. The second portion
21b of each of the breast contacting portions
211 has a second top stitching
27 that welds the first layer film
24 and the second layer film
25 to divide the second portion
21b into a first sub-portion
210a and a second sub-portion
210b. The first sub-portion
210a is located at a center of the breast contacting portion
211. The second sub-portion
210b is located between the second top stitching
27 and a top edge
211b of each of the breast contacting portions
211. When the pouch is filled with air, a second thickness
T2 of the second sub-portion
210b is lower than a first thickness
T1 of the first sub-portion
210a.
[0016] With reference to
FIG. 2C, the second portion
21b can be bent towards the concave portion
31b of each cup 31 by means of the first top stitching
26. When the pouch 21 is bent to conform to the curved shape of the breast
4, the first portion
21a can correspond to the bottom edge of the breast
4 to lift up the breast
4. The second portion
21b corresponds to the middle and the upper half of the breast
4 to squeeze and centralize the breast 4. Furthermore, the second sub-portion
210b can be bent towards each of the cups
31 and become closer to the concave portion
31b by means of the second top stitching
27. In this way, the first sub-portion
210a of the second portion
21b can correspond to the middle and the lower half of the breast
4, while the second sub-portion
210b can correspond to the middle and the upper half of the breast
4 to continue modifying the breast
4 along the first portion
21a to perfect the shape of the breasts of a human body.
[0017] According to the above descriptions, when the air pump
22 pumps fluids into the pouch
21, the pouch
21 is expanded for forming an air chamber in the pouch
21. Through the arrangement of the aforesaid top stitchings, the pouch
21 can be further divided into several portions, including the aforesaid first portion
21a and the second portion
21b (which may include the first sub-portion
210a and the second sub-portion
210b). To ensure air communication between the first portion
21a and the second portion
21b, at least one first passage
28 disposed between the first portion
21a and the second portion
21b passes through the first top stitching
26 so that the first portion
21a and the second portion
21b are in fluid communication with each other through the first passage
28. To ensure fluid communication between the first sub-portion
210a and the second sub-portion
210b, at least one second passage
29 disposed between the first sub-portion
210a and the second sub-portion
210b passes through the second top stitching
27 so that the first sub-portion
210a and the second sub-portion
210b are in fluid communication with each other through the second passage
29. That is, the air chamber in the pouch
21 is divided into several air sub-chambers, each of which may correspond to one portion
of the pouch
21. The air pump
22 may be disposed in the first sub-portion
210a of the second portion
21b of one of the breast contacting portions
211.
[0018] To prevent the bending angle of the pouch
21 from being limited when the pouch
21 is stitched on the brassiere 3, each first sub-portion
210a has a first width
W1 and each second sub-portion
210b has a second width
W2. The first width
W1 is larger than the second width
W2. Accordingly, the pouch
21 has a curved shape corresponding to the inside bottom edge
31a of each cup
31 of the brassiere
3. Each of the breast contacting portions 211 has a first portion
21a connected with the corresponding cup
31 only through the bottom edge
211a. Furthermore, the second portion
21b can be bent to conform to different sizes of the breasts by adjusting the first width
W1 of the first sub-portion
210a to be larger than the second width
W2 of the second sub-portion
210b.
[0019] It shall be appreciated that in other embodiments of the present invention as shown
in
FIG. 3, each of the breast contacting portions
211 of the pouch
21 may only have a first top stitching
26. Each of the breast contacting portions
211 may only be divided into the first portion
21a and the second portion
21b without any other sub-portions. The number of first passages
28 and second passages
29 may also be adjusted depending on practical demands, which will not be further described
herein.
[0020] With reference to
FIG. 2D, each of the cups
31 has an outer side area
32, and the brassiere
3 has two lateral wings
33 which are connected with the outer side area
32 respectively. Each of the lateral wings
33 has an adhesive layer
33b and a protective layer
33c. The protective layer
33c is detachably attached on the adhesive layer
33b so that the adhesive layer
33b is stuck on the lateral side of each of the breasts and attached directly on the
lateral side of the breasts under the armpits of a human body when the brassiere 3
is worn by the user. When the adhesive layer
33b loses its adherence due to repeated use, the user can replace only the lateral wings
33 to avoid resource waste.
[0021] FIG. 4A is a schematic view of a brassiere pad adjustable structure
5 of a second embodiment of the present invention.
FIG. 4B is a partial schematic cross-sectional view of
FIG. 4A. FIG. 4C is a schematic view of the brassiere pad adjustable structure
5 connected with a brassiere
3 according to this embodiment.
FIG. 4D is another schematic view of the brassiere pad adjustable structure
5 connected with the brassiere
3 according to this embodiment. The brassiere pad adjustable structure
5 of this embodiment may correspond to two breasts of a human body. In detail, the
brassiere pad adjustable structure
5 comprises a pouch
51, an air pump
52 and an exhaust valve
53. The pouch
51 is formed by a first layer film
54 and a second layer film
55 connected to each other to form a one-piece structure. The pouch
51 has two breast contacting portions
511 and a central passage portion
512. The central passage portion
512 is located between the breast contacting portions
511 and is in air communication with the breast contacting portions
511. This embodiment differs from the first embodiment of the present invention in that,
as shown in
FIG. 4B, the air pump
52 is disposed on either the first layer film
54 or the second layer film 55 in the central passage portion
512 of the pouch
51. When the air pump
52 is pressed, the air pump
52 is adapted to pump fluid into the pouch
51. An exhaust valve
53 is fixed on the pouch
51 so that the user can press the exhaust valve
53 and the pouch
51 simultaneously at any time as desired to exhaust the fluids in the pouch
51 to the exterior through the exhaust valve
53.
[0022] In practical application of this embodiment, the pouch
51 has a bottom edge
511a, while the brassiere
3 has two cups
31. Each of the cups
31 has an inside bottom edge
31a and a concave portion
31b. The bottom edge
511a of each of the breast contacting portions
511 is connected with an inside bottom edge
31a of each of the cups
31 respectively. A steel wire coil may be disposed at the inside bottom edge
31a of each of the cups
31. In this embodiment, the bottom edge
511a of each of the breast contacting portions
511 may be connected with an inside bottom edge
31a of each of the cups
31 by stitching, but in other embodiments of the present invention, the connection may
also be achieved by other means, for example, by adherence. This will be readily appreciated
by those skilled in the art and, thus, will not be further described herein.
[0023] In this embodiment, as shown in
FIG. 4A, the exhaust valve
53 is disposed on the first layer film
54 away from the air pump
52 and located on the central passage portion
512. However, in other embodiments, the exhaust valve
53 may also be optionally disposed on either the first layer film
54 or the second layer film
55 away from the air pump
52, or may be disposed in the air pump
52.
[0024] Like the first embodiment of the present invention, the brassiere pad adjustable
structure 5 in this embodiment can be bent to conform to the shape of the cups
31 and the breasts of a human body by means of a plurality of top stitchings. Each of
the breast contacting portions
511 has a first top stitching 56 that welds the first layer film
54 and the second layer film
55 to divide each of the breast contacting portions
511 into a first portion
51a and a second portion
51b. The first portion
51a is located between the bottom edge
511a and the first top stitchings
56 of each breast contacting portion
511. Because the brassiere pad adjustable structure
5 is connected with the brassiere
3 and a steel wire coil may be disposed at the inside bottom edge
31a of each of the cups
31, the first portion
51a is also located between the inner edge of the steel wire coils and the first top
stitching
56. The second portion
51b may correspond to the concave portion
31b of each cup
31. The second portion
51b of each of the breast contacting portions
511 has a second top stitching 57 that welds the first layer film
54 and the second layer film
55 to divide the second portion
51b into a first sub-portion
510a and a second sub-portion
510b. The first sub-portion
510a is located at the center of the breast contacting portion
511. The second sub-portion
510b is located between the second top stitching
57 and the top edge
511b of each of the breast contacting portions
511. When the pouch is filled with air, the thickness of the second sub-portion
510b is lower than the thickness of the first sub-portion
510a. Thus, an effect of lifting up the breasts by the first portion
51a, squeezing the breasts to centralize the breasts and modifying the shape of the breasts
by the second portion
51b can by achieved.
[0025] To ensure air communication between the first portion
51a and the second portion
51b, at least one first passage
58 disposed between the first portion
51a and the second portion
51b passes through the first top stitching
56 so that the first portion
51a and the second portion
51b are in fluid communication with each other through the first passage
58. To ensure fluid communication between the first sub-portion
510a and the second sub-portion
510b, at least one second passage
59 disposed between the first sub-portion
510a and the second sub-portion
510b passes through the second top stitching
57 so that the first sub-portion
510a and the second sub-portion
510b are in fluid communication with each other through the second passage
59.
[0026] Like the first embodiment, the number of first passages
58 and second passages
59 may be adjusted depending on practical demands. Each first sub-portion
510a has a first width and each second sub-portion
510b has a second width. The first width is larger than the second width. Accordingly,
when the first portion
51a is connected with the cup
31, the first sub-portion
510a and the second sub-portion
510b of the second portion
51b will not be connected with and limited by each of the cups
31, so they can be bent to conform to the shapes of different breasts.
[0027] With reference to
FIGs. 4C and
4D, each of the cups
31 has an outer side area
32. Each outer side area
32 has a first attached structure
32a in this embodiment. The brassiere
3 has two lateral wings
33. Each of the lateral wings
33 has a second attached structure
33a, an adhesive layer
33b and a protective layer
33c. The second attached structure
33a is detachably attached on the first attached structure
32a. The protective layer 33c is detachably attached on the adhesive layer
33b so that the adhesive layer
33b is stuck on the lateral side of each of the breasts and attached directly onto the
lateral side of the breasts under the armpits of a human body when the brassiere 3
is worn by the user. When the adhesive layer
33b loses its adherence due to repeated use, the user can replace only the lateral wings
33 to avoid resource waste. In this embodiment, the first attached structures
32a and the second attached structures
33a may be Velcro.
[0028] FIG. 4E illustrates a schematic view of another embodiment of the present invention. In another
embodiment of the present invention, the brassiere 3 has at least two buckle sets
35 and a brassiere strap
36. Each of the buckle sets
35 has a buckle
35a and a fastener
35b. The buckle
35a is disposed on the outer edge of each of the cups 31, while the fasteners 35b are
disposed on two ends of the brassiere strap
36 respectively. Each of the buckles
35a and each of the fasteners
35b are connected to each other so that the brassiere strap
36 is connected to the cups
31. Similarly, in other embodiments of the present invention, the two ends of the brassiere
strap
36 may also have a second attached structure
33a respectively so that the second attached structure
33a is detachably attached onto the first attached structure
32a. Thus, when the user is going to exercise or participate in other physical activitis,
she can wear the brassiere
3 of the present invention together with the brassiere strap
36 so that the brassiere
3 can be more securely fixed onto the breasts.
[0029] According to the above descriptions, the brassiere pad adjustable structure of the
present invention can effectively control the position of the air pump by disposing
the air pump in the pouch so that the brassiere pad adjustable structure is suitable
for various kinds of brassieres. Furthermore, by disposing a plurality of top stitchings
on the pouch, the pouch can be bent to conform to the shape of the breasts of a human
body and the shape of the brassiere to suit various shapes of breasts of different
users.
[0030] The above disclosure is related to the detailed technical contents and inventive
features thereof. People skilled in this field may proceed with a variety of modifications
and replacements based on the disclosures and suggestions of the invention as described
without departing from the characteristics thereof. Nevertheless, although such modifications
and replacements are not fully disclosed in the above descriptions, they have substantially
been covered in the following claims as appended.
