Abstract
A prophylactic includes a fabric layer reinforced by an inelastic weft extending in a longitudinal direction wherein the weft includes filaments woven with filaments of an elastic warp extending transversely, to allow the propylactic to stretch without breaks and leaks.
Description
The present invention relates to the improvement of latex contraceptives, this contraceptives has some and structural new configuration, and this new configuration improves the ruggedness of known contraceptives.The structure of contraceptives of the present invention improves its safety and effectiveness, reduces disruptive danger, and with economy and practical advantage as being described in detail in this description.
Have certain form so that make this contraceptives can be advantageously used in coating the interchange that penis is avoided aqueous fluids in the sexual act thereby known contraceptives is generally made with latex or similar elastomeric material.Reduced the propagation of many sexually transmitted diseases of serious threat whole world population therefrom.When considering contraceptives preferably with latex type or elastic-like material manufacture, this just exists the critical defect of contraceptives spontaneous breaking, and the inconvenience that causes owing to its common undesirable longitudinal stretching, this causes it to use because in the crucial moment possible leakage or the extremely danger that becomes of breaking.
Contraceptives of the present invention is much better than known contraceptives and has overcome the latter's unfavorable effect.Unknown new feature is included in to use the fabric that mixes and be included in the contraceptives of making in the manufacture process of contraceptives and mixes fabric before of the present invention.This fabric that mixes is by at vertical side's non-resilient parallel of braiding and parallel forms on the warp being fastened on the cross-sectional direction, to cause this contraceptives transversely having elasticity, compatibility and an adjustable with respect to its central axis, and with respect to above-mentioned axis vertically on be stiff, from and don't damage its compatibility.Extra wall thickness do not influence its adhesiveness with regard to having formed the total fracture-resistant of contraceptives like this or compatibility does not need extra contraceptives wall thickness yet, because in use may cause uncomfortable feeling.
For the ease of being expressly understood and easily implementing the present invention, an embodiment as its represented in this Figure of description preferred form is provided, in these accompanying drawings:
Fig. 1 is the perspective view of the improved contraceptives of the present invention, shows the feature detail view of the improvement weavy grain that this contraceptives mixes; Its planform and warp and parallel part are shown in line " A "-" A ".
Fig. 2 is the close up view of the fabric that is impregnated in, shows the elasticity of the elastic filament of fabric and fabric warp and at the elasticity of the fabric of direction indication and the rigidity long filament of the parallel on above-mentioned warp that interweaves, they all are incorporated in improvement weavy grain shown in Figure 1.
Fig. 3 is the example as alternative other embodiment of improved modification shown in Figure 1, in this structure, shows the warp elastic filament of its bearing of trend, and with the non-resilient longitudinal filament of the interlacing parallel of this warp elastic filament.The elastic warp long filament is shown in bearing of trend, and non-resilient longitudinal filament constitutes the parallel in the improved contraceptives fabric of the present invention.
In said all figure, identical label is represented identical or similar parts.
Now for the special structure that shows contraceptives (1) of improving of the present invention is described.As in Fig. 1 feature window the contraceptives (1) that shows in detail comprise the fabric (2) that mixes.Fabric (2) is made of the pattern weavy grain, figure stricture of vagina weavy grain consists essentially of stiff superfine long filament (3), this long filament (3) constitutes the parallel of weavy grain, this parallel is connected to superfine elastomeric filament (4), and long filament (4) constitutes the warp that is incorporated into fabric (2) weavy grain in the contraceptives (1).Fabric (2) is impregnated in the following manner: be formed on the end latex layer (11) that it is provided with the second layer (12) that also is latex.In case layer (11) is solidified with overlapping with (12), as shown in fig. 1, the bottom of the improved fabric of the present invention (2) is embedded in the matrix of contraceptives (1), and last with as thin as a wafer latex layer (3) applicator assembly and become unitary construction with the body of contraceptives (1).Contraceptives (1) is at last by with simple and effective and efficient manner shape molding according to the rules, since the improved assembly of the fabric (2) that forms by parallel (3) and warp (4) permission contraceptives (1) axis radially on carry out flexible adjustment, subsequently in the direction shown in the arrow f-f ' distortion, thereby avoid in the stretching of contraceptives (1) on vertically.Band is inhaled this structure of the contraceptives (1) of braided fabric (2) and has been eliminated the probability that produces be full of cracks or fracture in contraceptives (1), because textile fabric (2) has been eliminated longitudinal stretching, this longitudinal stretching is the reason of the most frequent generation be full of cracks just.Also can select other layer and with layer (11), (12) and (13) of contraceptives (1) layer that comes from different backgrounds and possess different abilities.
Thus can be clear and definite be, although the said structure of contraceptives of the present invention has shown a simple declaration example of being arranged in the embodiment of the invention, yet, this structure can be incorporated in the contraceptives made from latex layer between any latex layer, and does not influence equally as scope of the present invention or essence pointed in the appended claims.
Claims (2)
1. improved cylindrical body latex contraceptives with base end of open end and sealing, be included in the said contraceptives body structure and have the fabric that is impregnated in, this fabric has cross section elastic warp and non-resilient vertical parallel, and said parallel is with the longitudinal extension with respect to said contraceptives axis.
2. improved latex contraceptives as claimed in claim 1, wherein said fabric are embedded in said contraceptives between the multilamellar latex layer.
