Abstract
This utility model provides a kind of condom, and it is made up of elastomeric material, comprises body and the elastic ring being located at body opening end, it is characterized in that: described elastic ring is rolled up to stick on prefabricated elastic ring by the opening's edge part of body opening end and made.This utility model has following advantage: the elastic ring of condom has stronger " clamping force ", can effective lock ring penis, prevention condom landing and slow down the back-flow velocity of penile vein blood, impels erection to obtain more lastingly, harder.
Description
Technical field
This utility model relates to condom, particularly a kind of condom with stronger contining function.
Background technology
Existing condom, its elastic diameter generally only has about 1mm, and the contining function of generation is also very limited.If extracted out by penis not timely after ejaculation, condom landing to intravaginal, can cause possible contraceptive failure because of reducing of penis.If by the elastic ring overstriking of condom to suitable size, the generation of this phenomenon just can effectively can be reduced.
Therefore, China Patent No. be ZL201020601083.7 patent discloses a kind of condom.Its technical scheme is that body opening's edge part is rolled into overstriking type elastic ring integratedly by the elastic ring of condom.During use, the elastic ring energy lock ring penis of overstriking, reaches and prevents condom landing and the back-flow velocity of penile vein blood slowed down and reaches the object extending the erection time.But all know as the professional technique people of the industry, want to make the thicker method of this condom elastic ring only have one, Here it is: the glued membrane of the opening's edge part of being overlapped by conventional contraceptive and the stroke rolling elastic ring lengthen, the abundant glued membrane that impelled rolled-up elastic ring because of winding and thicker.And in fact, this seems simple scheme and is implementing very difficult, Here it is: must change existing mould and equipment when 1, manufacturing, cause cost of investment to increase.2, the ring footpath of elastic ring is difficult to the rugosity reaching expection, causes clamping force limited.
If there is a kind of change existing mold and equipment of not needing just can produce the lock ring condom with thicker elastic ring, one is decided to be consumer expected.
Summary of the invention
The purpose of this utility model is the deficiency in order to solve above-mentioned condom, provides one to adopt more short-cut method to manufacture lock ring type condom.
This utility model is achieved through the following technical solutions.
First this utility model provides a kind of condom, is made up of elastomeric material, and it comprises body and is located at the elastic ring of body opening end, it is characterized in that: described elastic ring is rolled up to stick on prefabricated elastic ring by the opening's edge part of body opening end and made.
The bore of described elastic ring is 25mm-35mm.
The ring footpath of described prefabricated elastic ring is 2mm-8mm.
The ring footpath of described elastic ring is 3mm mono-5mm.
This utility model also provides a kind of and utilizes existing finished product condom to prepare the preparation method of this utility model lock ring condom, it is characterized in that: which comprises at least following steps: a, previously prepared go out condom body and the body prefabricated mould suitable with it is propped up; B, prefabricated elastic band is placed on the mould of opening's edge part of next-door neighbour's body opening end; C, at the opening's edge part coated with adhesive of body opening end and the prefabricated elastic ring that rolls makes the opening's edge part of body opening end roll up sticks on prefabricated elastic ring; D, rolls forward elastic ring are to the demoulding, pack again.
This utility model reoffers a kind of preparation method manufacturing this utility model lock ring condom on the automatic production line of conventional contraceptive cover, it is characterized in that: it at least also comprises the following steps: a, use conventional contraceptive mold flood, dry in latex; B, prefabricated elastic band is placed on the mould of opening's edge part of next-door neighbour's body opening end; C, routinely condom crimping method carry out crimping makes the opening's edge part of body opening end volume be bonded on prefabricated elastic ring 4; The prefabricated elastic ring of d, rolls forward is to the demoulding, packaging.
Can learn from above technical scheme, elastic ring of the present utility model is the compound prefabricated elastic ring be made up on prefabricated elastic ring of the body opening's edge partial wrap of opening end.In implementation process, the mould of original condom, equipment and production technology need not be changed, as long as precast condom body according to a conventional method, then the opening's edge partial concentric of condom opening end be rolled up and is bonded at prefabricated elastic ring periphery.Adopt the lock ring condom produced in this way, also there is the unexistent advantage of known lock ring condom, Here it is: 1, compound prefabricated elastic ring has stronger " clamping force ", effectively can avoid condom landing and slow down the back-flow velocity of penile vein blood, impel erection to obtain more slightly, longer, more lastingly, more strong; 2. the ring footpath size of compound prefabricated elastic ring can be arbitrarily prefabricated as required, and manufacturing process is simple, cost of investment is low.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
See Fig. 1, Fig. 2.Lock ring condom of the present utility model, is made up of elastomeric material, and it comprises body 1 and is located at the elastic ring 2 of body 1 opening end, distinguished: elastic ring 2 is wherein sticked on prefabricated elastic ring 4 by opening's edge part 3 volume of body opening end and makes.
The bore of described elastic ring 2 is 25mm-35mm.
The ring footpath of described prefabricated elastic ring 4 is 2mm-8mm.
The ring footpath of described elastic ring 2 is 3mm-5mm.
See Fig. 3, Fig. 4, Fig. 5, Fig. 6, this a kind ofly utilizes existing finished product condom to manufacture the preparation method schematic diagram of this utility model condom, which comprises at least following steps: a, previously prepared go out condom body 1 and body 1 prefabricated mould 5 suitable with it is propped up (see Fig. 3); B, by prefabricated elastic ring 4 snare on the mould 5 of the opening's edge part 3 of next-door neighbour's body 1 opening end (see Fig. 4); C, at opening's edge part 3 coated with adhesive 6 of body 1 opening end and the prefabricated elastic ring of rolls forward 4 makes opening's edge part 3 volume of body 1 opening end stick on prefabricated elastic ring 4 (see Fig. 5); D, again rolls forward elastic ring to the demoulding, pack again (see Fig. 6).Certainly, also can on prefabricated elastic ring 4 coated with adhesive the prefabricated elastic ring of rolls forward 4 makes opening's edge part 3 volume of body 1 opening end stick on prefabricated elastic ring 4 (not shown).
In like manner, on the automatic production line of conventional contraceptive cover, adopt the condom preparation method that this utility model provides, it at least also comprises the following steps: a, use conventional contraceptive mold flood, dry in latex; B, by prefabricated elastic ring 4 snare on the mould of the opening's edge part 3 of next-door neighbour's body 1 opening end; The crimping method of c, routinely condom carries out crimping makes opening's edge part 3 volume of body 1 opening end be bonded on prefabricated elastic ring 4; D, rolls forward elastic ring are to the demoulding, packaging.
