Chest pad and there is the bra top of this chest pad
Technical field
The utility model relates to a kind of chest pad and has the bra top of this chest pad, can guarantee under the prerequisite of elasticity, crushing resistance and moulding effect, effectively the chest pad of weight reduction and have the bra top of this chest pad more specifically to a kind of.
Background technology
Brassiere is one of underwear of using of women, claims again chest measurement, brassiere, brassiere or brassiere, sometimes also with general term " underwear ", replaces, or laudatory title " inner beauty ", and its function is cover and support breast.Brassiere is derived from France, now generally all referred to as " Bra ".Former European noble is popular wears a kind of very close-fitting tunicle, but afterwards because this tunicle hell to pay, so use two handkerchiefs transformation of the way corselets instead, becomes the embryo of modern brassiere.Its structure generally includes two bra tops, two braces, two shoulder belts.Bra top is generally bowl-type, each 1 of left and right, the general figurate arc-shaped steel wire ring of lower limb, breast lower edge can be held up, its effect is the breast that supports the right and left, is topmost part, and bra top can be divided into full cup, 3/4ths cups and half cup according to area coverage.Described bra top generally includes external protection, chest pad and inner protective layer, and described external protection and inner protective layer are clipped in chest pad between external protection and inner protective layer.
At present, in order to play moulding effect, the elastic caoutchouc chest pad body that chest pad adopts the materials such as silica gel material (such as TPE, TPR etc.) to make conventionally, its advantage is: comfortable feel, crushing resistance be good, can play good supporting and shaping (moulding) effect to breast, but ordinary elasticity elastomeric material has many shortcomings.In order to improve, applicant develops and has applied for a kind of bra liner material, the patent No. is 200810220211.0, this material can effectively reduce the viscosity of bra liner, significantly reduce production costs, and have the following advantages: there is high resiliency, the soft also high resilience of bra liner made from this material, comfortable especially when brassiere is worn; There is good anti ageing property, long service life; Brassiere easy to clean, the deformed damaged of liner of can not causing; This material, not containing harmful material, is used safety; The bra liner temperature accommodation made from this material is large.But, by the improvement of material, the fault of construction that still cannot solve that it is airtight, weight is heavier etc.
For this reason, people have a plurality of air-vents between the medial surface of elastic caoutchouc chest pad body and lateral surface, are used for breathing freely.But, in order to guarantee its fixed effect, conventionally need to adopt thicker larger silica gel to guarantee its resistance to compression and moulding effect.
Although above-mentioned this design has solved ventilative problem, but due to elastic caoutchouc this body weight of chest pad or heavier, for fear of brassiere, user's breast is pulled down, cause user's breast tenesmus, brassiere need to adopt framework (comprising that the parts such as wire loop and structure form) that bra top is fixed and is located conventionally.
Although this method has solved the problem of breast tenesmus, but a large amount of results of study shows, the pressure of framework easily causes harmful effect to user's breast, and the weight of bra top (comprising the elastic caoutchouc chest pad body in it) can increase the weight of the pressure of framework to user's body, the long-term brassiere that uses this structure of user, easily cause user's breast uncomfortable, user's health is caused to harmful effect.
Summary of the invention
Technical problem to be solved in the utility model be heavier for prior art weight, easily user's health is caused to dysgenic shortcoming, a kind of chest pad is provided, this chest pad can guarantee under the prerequisite of elasticity, crushing resistance and moulding effect, effectively weight reduction.The technical scheme adopting is as follows:
A kind of chest pad, comprise elastic caoutchouc chest pad body, between the medial surface of described elastic caoutchouc chest pad body and lateral surface, have many through holes, it is characterized in that: the interior side opening of described each through hole is covered with the medial surface of elastic caoutchouc chest pad body, the outer openings of described each through hole is covered with the lateral surface of elastic caoutchouc chest pad body, and the shared volume of described all through holes is the 40-80% of elastic caoutchouc chest pad body cumulative volume.Owing to being covered with through hole in elastic caoutchouc chest pad body, therefore elastic caoutchouc chest pad body can be regarded as by the interior pipe of establishing through hole and form, if the shared volume of through hole is excessive, the wall thickness of these pipes is too thin, lack flexibility, if the shared volume of through hole is too small, do not reach the object of weight reduction, therefore the shared volume of all through holes is that the 40-80% of elastic caoutchouc chest pad body cumulative volume is proper.
Preferred scheme, the shared volume of described all through holes is the 50-70% of elastic caoutchouc chest pad body cumulative volume.Within the scope of this, can better take into account the performance of chest pad and the effect of loss of weight.
Scheme preferably, described all through holes are parallel to each other.Design is for the ease of processing like this, thereby reduces production costs.
Scheme preferably, the length of described at least 50% through hole is greater than the thickness at this place of elastic caoutchouc chest pad body.Design is in order to increase the length of through hole, can better to play a role like this; When the both ends open of some through hole is all sealed by gas impermeable material, just form a tracheae that is filled with air in it, length increases, and tracheae can store more air so, further strengthens the elasticity of tracheae.
Scheme preferably, the length of described through hole is at least 1 millimeter.
Scheme preferably, described any two adjacent through-holes spacing ranges are 1-5 millimeter.
Scheme preferably, the pore diameter range of described through hole is 2-10 millimeter.
Scheme preferably, the aperture of described through hole be any two adjacent through-holes spacing 2-4 doubly.
Scheme preferably, the edge of described elastic caoutchouc chest pad body leaves joining edge.
Another object of the application, is to provide a kind of bra top with above-mentioned chest pad, and concrete scheme is as follows:
A kind of bra top, comprise external protection, chest pad and inner protective layer, described external protection and inner protective layer are clipped in chest pad between external protection and inner protective layer, it is characterized in that: described chest pad comprises elastic caoutchouc chest pad body, between the medial surface of described elastic caoutchouc chest pad body and lateral surface, have many through holes, the interior side opening of described each through hole is covered with the medial surface of elastic caoutchouc chest pad body, the outer openings of described each through hole is covered with the lateral surface of elastic caoutchouc chest pad body, the shared volume of described all through holes is the 40-80% of elastic caoutchouc chest pad body cumulative volume.
Scheme preferably, the both ends open of described at least one through hole is all sealed by gas impermeable material, forms the air elastic tube that is filled with air in it.These air elastic tubes can further strengthen the performances such as elasticity of chest pad.
The utility model beneficial effect is against existing technologies, because chest pad can guarantee under the prerequisite of elasticity, crushing resistance and moulding effect, effectively weight reduction, therefore adopt the bra top of this chest pad manufacture not only can help user to mould perfect image, and can avoid causing excessive burden to user's health, prevent user's health to cause harmful effect.
