Description

Fill-in apparatus for sanitary sliver

The present invention relates to a kind of can be used to being suitable for stopping up vaginal canal to absorb and to keep the tapon of menses to be incorporated into tent device in the vaginal canal.

Is small and exquisite in order to provide a kind of at it in form, packing and carrying is the tent device of tapon easily, the applicant is at United States Patent (USP) 4,921, a kind of tent device of tapon is disclosed in No. 477, the inner sleeve that in general this tent device comprises that an outer sleeve and that can hold cotton sliver is inserted in the outer sleeve slidably and can release through its forward opening cotton sliver from outer sleeve, wherein, inner sleeve is made up of second internal member that one first internal member and is inserted in first internal member slidably, when second internal member pulls back with respect to first internal member, can make the rear end of first internal member be connected to the front end of second internal member.Prior art set forth above has been done enforcement.

But after having proposed above-mentioned tent device, the applicant is based on successive, and experimental study has repeatedly found that several aspects must be further improved, and improved part will be described as follows.

Aspect application tent device and cotton sliver, some do not have experience or the few user of experience, in use, often can not adopt correct posture or can not insert the tent device with nature, the appropriate angle with respect to vaginal canal.Therefore, when pushing tent device was released cotton sliver, the front end of cotton sliver trended towards running into vaginal wall, so produce sizable resistance to inserting.The result, engage at described first internal member and described second internal member on the position of (connection) and will bear excessive load, thereby these internal members are disengaged mutually, so that second internal member might be in the first internal member slides forwards, thereby make second internal member can not promote first internal member.So first internal member no longer may be pushed into cotton sliver in the vaginal canal.Although this problem can solve by the intensity that improves each appropriate section that cover engages in first internal member and second, but will making with respect to first internal member, this measure increases toward the required pulling force of post-tensioning second internal member, enter the state of being bonded with each other until them, this just correspondingly makes relatively difficulty of this joint.

Article one, the rope that is used for pulling out in the cotton sliver tent device is by being guided out by circumjacent second internal member of first internal member, and this rope stretches out from the rear end of tent device, and outside the rear end of second internal member is exposed to.Usually, the user has no doubt that rope is ined succession and the situation that is connected of rope and cotton sliver is good, but aspect the cotton sliver of using the tent device, whether some do not have experience or the few user of experience to tend to reliably worry with the situation that is connected of cotton sliver for stay cord.

Therefore, the present invention seeks to solving the above problems, but the advantage of the tent device of above-mentioned well-known tapon then will be kept.

In order to reach purpose set forth above, the invention provides a kind of tent device of tapon, this tent device generally includes an outer sleeve and that is suitable for holding a cotton sliver and is inserted into slidably in the described outer sleeve, be the inner sleeve that described cotton sliver is released through its front opening from described outer sleeve, described outer sleeve comprises that one is positioned at first grade of ring of end thereafter, described inner sleeve is made up of second internal member that one first internal member and is inserted in described first internal member slidably, described first internal member comprise one be suitable on its front opening can with second grade of ring and of described first grade of ring engagement third gear ring on the opening in its back-end, and described second internal member is containing one when described second internal member is pulled back on its front opening, be suitable for that fourth speed ring and with the engagement of described third gear ring is positioned at behind the described fourth speed ring and with its in line the 5th grade of ring axially, and stay one and allow the third gear ring to place the 4th and the 5th grade of space between the ring, wherein said third gear chain rate the described the 4th and the 5th grade of all easy strain of ring, when in case described third gear ring enters the state that is engaged between the described the 4th and the 5th baffle ring, when described first internal member and described second internal member were subjected to axial compressive force, described engagement had 600 gram or above load ability to bears.

In a preferred embodiment, described first internal member is provided with the 6th grade of ring so that described second internal member is unlikely moves to the described first internal member front opening direction on its end opening; Described the 5th grade of ring and described fourth speed ring are more or less than the fourth speed ring together, tilt gradually downwards backward on the axis direction of described second internal member and are to maintain static; Described second internal member opening in its back-end is provided with diameter at least greater than the expansion of the open rearward end of described first internal member; Described outer sleeve is by making than described first internal member and the soft material of the described second internal member quality; And described first internal member is to be made by the material that the material than described second internal member comes softly; And described outer sleeve and described second internal member are opaque, and described first internal member is transparent.

The tent device that is constituted according to the present invention, when cotton sliver did not use, second internal member was positioned at first internal member, and the 6th grade of ring is engaged between the 4th and the 5th grade of ring to prevent that second internal member from moving axially.When second internal member pulls back, the fourth speed ring will be crossed over the 6th grade of ring backward.When can second internal member further is pulled rearward in axial sliding, the 5th grade of ring makes the third gear ring produce elastic deformation backward, is with between four and the 5th grades of rings until the third gear ring is engaged on thereby cross over it in same direction.

Like this, first and second internal members just interconnect.Thereby, can by first internal member cotton sliver be released from the front opening of outer sleeve by on the expansion that forms on the rearward end that is pressed in second internal member.

The present invention can from below in conjunction with accompanying drawing to description that embodiment did and better understood, wherein

See also Fig. 1 to Fig. 3.Wherein the tent device comprises that an outer sleeve 2 and that wherein can insert (holding) cotton sliver 1 inserts the inner sleeve 3 in the outer sleeve 2 slidably.Outer sleeve 3 is to be formed by the opaque synthetic resin molding as polyethylene, and the material of trocar sheath is soft than the material of inner sleeve 3.

The front end of outer sleeve 2 is leading section 4 closures of cracking with petal-shaped, this leading section 4 can be opened it when cotton sliver pushes away forward forcibly, and the diameter of end reduces with the shelves ring 5 that forms an annular table shape to some extent and is being provided with an annular lip 6 around its rear end opening part thereafter.When using cotton sliver 1, shelves can be encircled 5 and flange 6 between the reduced diameter portion branch of the outer sleeve 2 that extends be clipped between the finger of user.It is to be noted that if desired, the rearward end of outer sleeve also can be that diameter is not reduced.

Inner sleeve 3 comprises that one first internal member 7 and can be slided is inserted into second internal member 8 in first internal member.First internal member 7 be molded as by transparent synthetic resin resemble the polypropylene and on the outer peripheral face of its front opening, be provided with an annular lip 9, this flange 9 can encircle 5 with shelves and be meshed, and makes therefrom that first inner sleeve 7 is unlikely to skid off backward from outer sleeve 2.First internal member 7 also comprises an annular shelves ring 11 that forms on the inner peripheral surface of opening in its back-end at the annular shelves ring 10 and that forms on the inner peripheral surface of its front opening.Second internal member 8 is to be formed by the opaque synthetic resin molding as polypropylene and so on, and this synthetic resin material is harder than the material of first internal member 7.Second internal member 8 comprises a shelves ring 13 that forms on the outer peripheral face of its front opening, this grade ring 13 is external along all being successive on the circumference except the relative notch portion of a pair of diametric(al), a pair of fixing shelves ring 14, this grade ring 14 are respect to one another and axially spaced apart in line with each otch part 12 on diametric(al).Each grade ring 14 all has the cross section of inequilateral triangle and the front surface of vertical and slight bending (Fig. 3 and 4) at axis direction.This notch portion 12 and not only can make second internal member 8 after molding process, be easy to from mould, take out but also can make the leading section of second internal member 8 be easy to elastic deformation on diametric(al) with the structure of described notch portion 12 shelves ring 14 in line respectively.

See also Fig. 4 now.Wherein, shelves ring 13 is the same high with shelves ring 11 basically, and shelves ring 14 is lower than shelves ring 13 and recedes, so that shelves ring 14 can stride across shelves ring 11 when second internal member 8 pulls back.Spacing between shelves ring 13 and shelves ring 14 is to select to such an extent that shelves ring 10 and 11 can be placed therebetween.In addition, second internal member 8 is that the open rearward end place is provided with loudspeaker or funnel shaped expansion 15.The diameter of expansion 15 is at least greater than the diameter on first internal member, 7 open rearward end, and preferably equals or the diameter on the outer sleeve open rearward end.Expansion 15 is after second internal member 8 inserts first internal member 7 by its front opening in advance, the open rearward end of second internal member 8 is pressed on the thermal forming device and forms.Should be noted that the rearward end of second internal member 8 also can be the wall of thickening, to form the inside annular protuberance 15 ' of one side, as shown in Figure 7.

The elastic deformation of shelves ring 11 should than shelves encircle 13 and shelves ring 14 more be easy to generate and first internal member 7 and second internal member 8 applied under the axial compressive force, shelves rings 11 engagement ground are in shelves ring 13 and shelves encircle 14(Fig. 2 to 4) between state the time the load-carrying ability, should be 600 grams or more more, being preferably 800 grams and being more preferred from 900 grams or more more, is very important.Here said load-carrying ability is meant when the front surface institute applied pressure of shelves ring 14 surpasses this load-carrying ability, and shelves ring 11 will be by elastic deformation, thereby crosses shelves ring 14 backward, and the result removes the load-carrying ability of described engagement.

For satisfying above-described requirement, there are all measures to take.For example, molded and make shelves ring 11,13 and 14 as shown in the figure during structure by polypropylene at first and second internal members 7,8, first internal member 7 can have the wall thickness of 0.5-1mm, and shelves ring 11 can have the height of 0.5-1.5 and the thickness of 0.5-1.5mm.Second internal member 8 can have the wall thickness of 0.7-1.2mm, shelves ring 13 can have the height of 0.5-1.5mm and the thickness of 0.5-1.5mm, each grade ring 14 can have the height of 0.25-1.3mm and 10-12 ° angle at its leading section, and the interval between the front portion of the rearward end surface of shelves ring 13 and shelves ring 14 can be 0.6-1.7mm.Though the present invention is not limited to these specific numerical value, because these numerical value all depend on the particular type of material and additive,, previous example will provide many useful data for those skilled in the art.

The front was said, aspect application tent device and the cotton sliver experience or the few user of experience must arranged, when using them, often can not take correct posture or can be with nature, insert the tent device with respect to the appropriate angle of vaginal canal, the result, using the tent device so that cotton sliver is released, the leading section of cotton sliver can be run into vaginal wall, thereby produces sizable resistance to inserting.The result, have in the position that first internal member 7 and second internal member 8 are bonded with each other and to hold the load that can't stand, thereby make these internal members disconnected from each other,, thereby make second internal member 8 can't promote first internal member so that second internal member 8 might slide to the place ahead in first internal member 7.So far, first internal member also can not be advanced to cotton sliver in the vagina and go.The present invention has utilized the relation between elastic deformation and the load-carrying ability, thereby when second internal member 8 was pulled back, described engagement can realize reliably and described problem is eliminated.Specifically, when cotton sliver 1 was released, described engagement got loose, and no longer may take place thereby make second internal member 8 slide to the problem that the place ahead and second internal member 8 can not promote first internal member 7 in first internal member 7.Based on secular experimental study; comprise that test and monitoring are by the tent device that cotton sliver 1 wherein be housed of unfamiliar and experienced user's use according to made of the present invention; although the inventor finds that described engagement can be by pulling back second internal member 8; even just pull back and can realize with medium pulling force, if but just cause described problem less than 600 grams through regular meeting according to the described load-carrying ability of statistics.Because appropriate load-carrying ability depends on a certain user and uses the situation of the mode of the tent device that cotton sliver wherein is housed and user's vaginal canal that therefore, the described 600 gram load-carrying abilities of can not drawing a conclusion are threshold values.But, 600 restrain the data that these values are based on experimental study and get, and therefore, are actually a basic demand.As mentioned above, the outer sleeve 2 and second internal member 8 all are that opaque first internal member 7 then is transparent, its reason is as follows: concerning the user, the transparency of first internal member 7 only, just be enough to the naked eye see that one section is connected on the cotton sliver 1, extend to the stay cord of the part of close described stay cord 16 cardinal extremities from the centre, thereby obtain the security.If it is transparent that outer sleeve 2 is made, then the external morphology of the assembly of being seen through outer sleeve 2 says there is not what captivation from aesthetic view point, because by molding process, in fact be difficult to obtain attractive aesthetically cotton sliver 1 surface.Even it is transparent that second internal member 8 is also made, the user also can only confirm that part of stay cord near rearward end, and this deficiency thinks that the user provides the security.The inventor is from testing discovery, and transparent 7 couples of users of first internal member have preferable psychological effects, just makes the user produce a kind of security stay cord and is being connected with cotton sliver 1 reliably.

The tent device that cotton sliver is housed as mentioned above can be assembled by step shown in Figure 6.Specifically, cotton sliver 1 first being touched by hydrophilic fibers by conventional method with stay cord 16 made described shape.Outer sleeve 2, the first internal members 7 and second internal member 8 also are molded as described shape separately by conventional method by thermoplasticity synthetic resin.Then, after first internal member 7 has inserted in the outer sleeve 2, second internal member 8 is inserted in first internal member 7, perhaps second internal member 8 is inserted in the outer sleeve 2 behind reeve first internal member 7 earlier more together.When inserting, shelves ring 10 is engaged between shelves ring 13 and the shelves ring 14, and second internal member 8 can not be slided at axis direction.At this moment, cotton sliver 1 is inserted in the outer sleeve 2, stay cord was guided second internal member 8 and was exposed to the outside from its outer end opening, then, seam end 4 was arranged to close the front opening of outer sleeve 2 by well-known molding process hot-working is petal.The open rearward end of second internal member 8 be pressed on the thermosetting device with the closing simultaneously of the front opening of outer sleeve, or form described expansion 15 before this or afterwards.After the tent device assembles like this, can see by first internal member 7 in part near the stay cord 16 of its end.

According to the tent device of the invention described above made, when cotton sliver 1 does not use, as shown in Figure 1, second internal member 8 in first internal member 7 and shelves ring 10 be engaged between shelves ring 13 and the shelves ring 14 to prevent that second internal member 8 from moving axially.When cotton sliver 1 used, because shelves ring 10 has the required minimum constructive height of locking effect and preferably also has arcuate shape, when second internal member 8 pulled back, shelves ring 13 can be crossed over shelves ring 10 quite smoothly backward.Because first internal member 7 and second internal member 8 are made by synthetic resin, their elastic deformability also helps 13 need of shelves ring to overcome lower resistance just can to cross over shelves backward and encircle 10.When can axially movable second internal member 8 being pulled rearward further, shelves ring 14 makes shelves ring 11 do elastic deformation backward, thereby crosses over shelves ring 11 backward until shelves ring 11 was engaged between shelves ring 13 and the shelves ring 14, as Fig. 2 to shown in Figure 4.

The tapon tent device of formation and use will be avoided aforesaid problem effectively according to the present invention, promptly the use in tent device and the cotton sliver there are not experience or the few user of experience, in use do not take correct posture probably or not with nature, the appropriate angle with respect to vaginal canal is inserted, therefore, when the tent device is moved and cotton sliver is released, the front end of cotton sliver might be run into vaginal wall, produce sizable insertion resistance, the result is subjected to unaffordable load at first internal member and the second internal member engagement place, make these internal members break away from engagement mutually, cause second internal member in first internal member, to move forward.First internal member can't be released cotton sliver.After having overcome the problems referred to above by the present invention, first internal member can be pushed into cotton sliver in the vaginal canal reliably.In addition, owing to cross over the third gear ring third gear ring was engaged between the 4th and the 5th grade of ring, thereby between first internal member and second internal member, can reaches reliable connection (claim 1 and 2) at the 5th grade of ring under the elastic deformation of third gear ring.Be used for cotton sliver can be seen by first internal member from stay cord bottom that the tent device is pulled out and close with it part, can remove for this reason whether the user reliably is connected with cotton sliver stay cord and the worry and the uneasiness that produce.
