Description

Improved scouring group's ball and lacing method

Technical field

The present invention relates generally to wash and clean the field of utensil and relate to the method for making this utensil.The present invention is specifically related to the improvement of the polymeric web fabric group ball that personal hygiene uses and the improvement of manufacture method thereof.

Background of invention

Known in the art and utilized various swabs.For example adopted polymeric web fabric group ball to clean vegetable dish, pallet, other household wares and people's skin.The swab that is used for personal hygiene is commonly used to clean skin, the common polymeric web fabric group ball that is called.These polymeric web fabric group balls are made of the mesh of one or more pieces synthetic perforates usually, and this mesh is tightened together, nurses one's health into many unordered folds then, form spherical substantially shape or the group's of formation ball at last.The open-celled structure of mesh is preferably formed as the structure that can effectively clean health, and this structure can be removed the foul on the health easily and can at a good pace be dried.In addition, synthetic material elasticity is very big, thereby group's ball keeps its shape invariance in whole use.The formation method of these balls is, tightens the tubular mesh of a slice or a slice mesh with one section cord around central point, adopts various methods of operating to form a series of fold around this central point then.

For example the U.S. Patent No. 3343196 of Barnhouse discloses a kind of method of making group's ball of the open cell mesh fabric.Some mesh sheets are united by a seam at common central point, pass a locating ring then, this ring makes the mesh sheet be divided into round substantially profile.Then shear and compress these sheets, make between compression period, to form a series of folds.For good and all fold is being fixed together with the metal mounting board around central point.

The U.S. Patent No. 5,144 744 open another kind of methods of making group's ball with the polythene net fabric with rhombus open-celled structure of Campagnoli, this patent is included in herein as a reference.At the tubular mesh (promptly stretching) that stretches of the direction transverse to its longitudinal axis in direction transverse to the pipe theoretical centerline.The pipe that will stretch is contained between the relative supporting member of pair of curved then.Tighten pipe at the central point of its transverse axis subsequently, and pipe is selectively thrown off with supporting member, make that last product is the scrubber of the substantially spherical that forms of the unordered fold by a series of mesh materials.

For the member of tightening the tubular type mesh, Campagnoli usually proposes to use " plastic tape " of tightening usefulness.The pawl type strap arrangement that employed for this purpose a kind of " plastic tape " is plastics, these strap arrangement are often used in the electrical industry configuration and tie up electric wire or bunch of cables, are used to tie up plant in agricultural, or are used for sealed bag, bag and similar articles.This strap arrangement is usually by tying up the band that tooth is arranged for the treatment of girding articles and being used to make the elongated insertion part with stop pawl of this band fix in position or similar locking mechanism to constitute.Though be suitable for tightening group's ball of polymeric web fabric, use these strap arrangement to make the mesh tightening piece and also have some problems.These problems comprise scratch and damage user (promptly hurt, scratch or scratch user because there is the tail end of cingulum after pruning, also to have very sharp edge or protuberance at plastic strip.

Except that using plastic tape, in this technology, also use fiber or synthetic cord or the rope that interweaves of for example restricting to tighten polymeric web fabric group ball as everyone knows.Yet these cordage soakedly and dry are tended in time course crackedly or rotten owing to periodic between the operating period, and usually scatter, and cause lack the service life of a ball.Scattering also owing to tie a knot improperly during fabrication of this rope and is difficult to the urgent knot that stretches tight and is difficult to keep tight property when guaranteeing knotting.General polymeric web fabric group ball of not wishing to have above-mentioned characteristic is because dissatisfied this kind product of client.

Therefore the mesh tightening piece is not also reached requirement, this tightening piece should be able to can not damage the user around for good and all fastening mesh group's ball of central point.More particularly, this mesh tightening piece should be without any may incised wound, scratch, scratch user or contact user's sharpened surface in other bad mode, and can tie up and tighten simultaneously polymeric web fabric group ball fully, its shape is kept.

Brief summary of the invention

A kind of swab is provided, and this device comprises pipe and a kind of mesh tightening piece that does not fray basically and don't cause injury that is used for forever tightening basically the mesh pipe of at least one open cell mesh fabric.This swab is by constituting along uphold each mesh pipe transverse to the direction of the longitudinal axis between relative pair of curved supporting member.Preferably around the virtual center point of mesh pipe adopt the mesh tightening piece basically around with tighten the mesh pipe.If swab is made of more than one mesh pipe, then should restrain tightly together at the virtual center point habitat of about pipe with the mesh tightening piece, form common central point thus.Make each mesh pipe selectively throw off relative supporting member then, and conditioning like this, make to form a series of unordered fold.The free end of this fold is preferably formed as the swab of reservation shape.If the virtual center point of each tubular mesh is generally along the centre of tubular mesh transverse axis between relative supporting member, then swab will form sphere substantially.

The accumulation point that five kinds of mesh tightening pieces tighten enduringly securely the virtual center point of single mesh pipe or tighten the active centre point of many pipes is proposed.The locking tether has cord (rope) and jig, can with this tether knot basically around with tighten the mesh pipe.Jig is bundled in cord on the mesh pipe securely by the adhesion of mechanical force and frictional force or crimp force.Another kind of mesh tightening piece is an interlocked rings, and this ring has the inclination protuberance of at least one groove on many engagement interlocked rings, thereby annular is become around the shape of the cardinal principle circle of mesh pipe.Another mesh tightening piece is continuous elastic ring, this elastic ring constraint mesh pipe.Another mesh tightening piece is fixing the disconnected tether of girth, and this tether has the locking barb on feed shelf, and this feed shelf is connected in recipient by a flexible piece.The formation method of another mesh tightening piece is when the mesh pipe is stretched between relative supporting member the mesh pipe to be heated cramping.

DETAILED DESCRIPTION OF THE PREFERRED

Describe existing preferred embodiment now in detail and make the preferred method of the present invention, the example of preferred embodiment is shown in the drawings, and identical numbering is represented same parts in institute's drawings attached.Because can think, just the present invention may be better understood and structural member of the present invention to understand the method for manufacturing described below structural member of the present invention, so below with reference to method for optimizing that Fig. 1～3 explanations are made.

Fig. 1 illustrates two mesh pipes 20 and 22, this pipe is best to be stretching between a pair of relative bent support 24a, 24b, 26a and the 26b theoretical center line drawing of each mesh pipe (promptly transverse to) transverse to its longitudinal axis, and in a bit assembling towards support bases.When being in the state of stretching, tighten the mesh pipe securely with the lasting basically mesh tightening piece 30 of non-fraying property, form the common center point 32 of compiling the mesh pipe thus.The said term of this paper " common center point " is meant basically by the formed position of the virtual center point gathering of each mesh pipe or alignment.Term used herein " virtual center point " is meant along a position of the lateral shaft of each mesh pipe between supporting member (being 24a, 24b, 26a, 26b) that stretches tight.This virtual center point is preferably substantially near the transverse axis of each mesh pipe and the intersection point of the longitudinal axis, though be suitable for other embodiment equally along other position of the longitudinal axis.

Tightening mesh pipe (for example 20,22) with mesh tightening piece 30 afterwards, making the selectively its corresponding bent support of each weaving QC throw off and nurse one's health, forming many unordered fold 34, seeing as Fig. 3 is clear around common center point.The fold of assembling is preferably formed as the spherical polymeric web fabric group ball 36 that is roughly as shown in Figure 4.Though the method for making polymeric web fabric group ball 36 has been described, this bag is drawn together two mesh pipes, this pipe is tightened the formation common center point, but the professional and technical personnel should understand, said method also is applicable to the virtual center point of tightening single mesh pipe, forms group's ball 36 of another embodiment.

The method for optimizing of making polymeric web fabric group ball 36 has been shown above, the preferred structure of the group's of the following describes ball 36.Each mesh pipe (for example 20,22) preferably has many independent perforates.The structural change scope of each perforate can be very wide and can not run counter to the effectiveness of group's ball that scope of the present invention or influence produce, and the two determines the structure of this perforate by the size and dimension of independent perforate.In a preferred embodiment, the shape of each perforate can be rhombus mesh form.The most handy elastomeric any polymer of each mesh pipe for example polyethylene is made, and also is suitable for but the professional and technical personnel should be understood that other polymer, metal, fiber blends or materials similar.Equally, also can arbitrarily change the physical characteristic (for example molecular weight, molecular weight distribution, melt index (MI) etc.) of the material that is used to form each mesh pipe, to reach the final characteristic (for example elasticity, flexibility etc.) that is suitable for intended purpose and without prejudice to scope of the present invention.

Thereby the following describes be used to tie around with tighten at least one mesh pipe and form five preferred net fabric tightening pieces of central point 32.Each preferred mesh tightening piece 30 be non-scratch and be lasting basically.Term used herein " non-scratch " refers to a kind of like this mesh tightening piece 30, and it does not make us producing Roughen Edges, protuberance or the outwardly directed structural member of unhappy sense of touch (for example incised wound, cut wound, scratch, fray or the damage that user's sensing surface is produced of other form) in use basically easily.In addition, the structure of each preferred net fabric tightening piece 30 is to make it to tighten polymeric web fabric group ball 36 basically enduringly and can not scatter or otherwise unclamp at the usual terms of for example making, transport, selling and use.

Shown in Fig. 5～7 were clear, a kind of such device of tightening was a locking tether 32, and it has flexible cord 34 and locking jig 36.The article that jig wedge shape or taper with internal lock structure (for example tooth, conic-insertion-piece, slide lock) has been used to be limited in manufacturing are rope and the motion wiry in clothes, body-building and sports equipment and the electrical box for example.For example this jig formula structure has been used at the object of making for example engagement and fixing cord in the handle of footwear, jacket, sack, underwater exercise device and health and fitness facilities.Aspect electric, the locking jig has been used to lead anchor is fixed on the electric power delivery casing is passed in its position on the electric power delivery casing at lead tapping.

Though similar above-mentioned jig formula structure on locking jig 36 structures, the function of the jig 36 of locking tether 32 is engagement cords 34, makes 34 pairs of mesh pipes 20 of cord and 22 keep lasting basically tight Shu Li.This cord 34 preferably has free end 38 and closed end 40 when cooperating with jig 36.Passage 42 is isometric with jig 36, and this passage has intake section 44 and exit portion 46.Being configured in around passage 42 internal diameters is many independent inclined teeth 48, and the size of this tooth and inclination angle make cord 34 to cross passage 42 and can not disturbed basically along direction D.If yet tension force act on the cord 34, as what happens on fully being fastened to the mesh pipe time, tooth 48 will mesh cord 34, as shown in Figure 7, can prevent that thus locking tether 32 unclamps.Clearly, the size of jig 36 is made to and can holds the very big cord of external diameter excursion 34.Though jig 36 preferably is made up of passage 42 and tooth 48, clearly, also can reach the engagement of jig 36 with other equivalent structure.For example jig 36 can comprise the seam that extends along its length basically, makes jig 36 can be crimped on cord 34 enduringly.

Should be understood that cord 34 can be with any flexible fiber or for example making such as polypropylene, nylon of synthetic material, this cord can be resisted the illeffects of other liquid that periodically is subjected to water or may runs into during use.Jig 36 is the most handy to be any material for example metal, timber, glass fibre or the plastic production of rigidity substantially.Yet because economic reasons, jig 36 the most handy acetal plastics are made of injection molding process, and for example Plastic Welding or adhesive connect the method for suitable parts but also can adopt other method.

Mesh pipe 20 and 22 the most handy locking tethers 32 are tied up, and method is at first to use cord 34 virtual center point of surrounding tube basically, then intake section 44 is preferably passed at the two ends of cord simultaneously, stretches out exit portion 46 until two ends.Traction cord 34 is by jig 36, strains fully and pushes and tighten the mesh pipe until cord 34.Under this condition, the tooth 48 of inclination will make cord 34 locks in place, thereby obtain the lasting basically tight Shu Zuoyong to a ball that the effect of the power backward that the extension owing to cord causes produces.The free end of this cord can be as the handle or the suspension strop of group's ball.

Another kind of preferred net fabric tightening piece 30 is interlocked rings 50, shown in Fig. 8 and 9.The common extruding clip that is called of interlocked rings, it has been used in pipeline engineering and the auto industry flexible pipe and pipe has been fixed on connecting elements (for example cuff, pipe joint, ozzle etc.).These extruding clips generally comprise flexible band, utilize the devices such as pawl, tooth of interlocking will should seal into circular shape by the flexibility band.They can be taken off from interconnecting component frequently, so that safeguard, repair and cleaning flexible pipe or pipe.

Interlocked rings 50 is structurally similar, but does not play above-mentioned extruding clip.Interlocked rings 50 has first end 52 and the second end 54.First end 52 preferably has the protuberance 56 of many inclinations.The second end 54 preferably has many grooves 58 that cooperate with protuberance 56, if it is circular substantially to make that interlocked rings 50 is closed into, just the protuberance 56 of inclination and groove 58 be hooked in together, thereby can be closed enduringly basically and fixing interlocked rings 50.Simultaneously, in the basic circle of this closure, the interior compression stress that ring 50 will afford the internal tension from the center curvature axle (promptly do not have power effect axle) of ring to outer surface 58 effects and act on to inner surface 59 from the center curvature axle of ring.This synergy of tension force and compression stress generally will be revolted the engagement of inclination protuberance 56 and groove 57, make ring 50 get back to its relaxed state.Interlocked rings can be made of the elastomeric material of any flexibility, for example makes of acetal plastic, and this material can be resisted the illeffects that periodically is subjected to water and other other liquid that can run into during use basically.

Mesh pipe 20 and 22 is preferably tightened like this, promptly at first launches interlocked rings 50, and with this this encirclement of cyclic group mesh pipe.Make the protuberance 56 and groove 58 engagements of inclination then, press cooperation as mentioned above until them, thereby make interlocked rings 50 fixing.

Another preferred net fabric tightening piece is continuous elastic ring 60, shown in Figure 10 and 11.The elastomeric polymer ring is common to be called O shape ring, and they generally are used on the pipeline in fluid and the gas device (for example valve, storage or saving device, pump etc.), flow to the device of another part from a part of device as a kind of fluid that prevents.In addition, these O shape rings also can be used among medical science and the animal doctor, and being used in needs to clamp in the process of organ or tissue, in case hemostasis liquid flows to this organ or tissue (for example using) in the castrating process of domestic animal.

Ring 60 is similar on structure and composition substantially, but does not play above-mentioned O shape ring.Ring 60 preferably has continuous cardinal principle circle, and its size makes and still be in tensioning state when tying the mesh pipe, thereby can apply the firm lasting power of tightening.The ring 60 elastomeric material of handy flexibility is made, and this material can not degenerate because of the periodic illeffects of other fluid of being subjected to water or running between the operating period basically.Ring 60 the most handy natural rubbers or elastomeric polymer such as silicon rubber, poly-different the eleventh of the twelve Earthly Branches diene or similar material are made.

Tighten the mesh pipe with elastic ring 60, method is at first to open elastic ring 60 and it is enclosed within downwards on the supporting member (for example 24a, 24b, 26a or 26b).After opening and be placed on the mesh tube stay on the supporting member, elastic ring is elevated to the top of supporting member, be fixed on the central point of pipe then.

Another preferred mesh tightening piece is the tether 62 that can disconnect, shown in Figure 12～15.The tether 62 that can disconnect preferably has bar of presenting 64 and recipient (boots seat 66).Present bar 64 and preferably have at least one and be configured in the locking barb of presenting on the bar 64 68, make the tether 62 that can disconnect can tie fully around with tighten mesh pipe 20 and 22.Shoulder shape brake component 69 is preferably near barb 68.

Recipient 66 preferably has inner chamber 70 and intake section 72 and exit portion 74.Be configured in the inner chamber 70 is (bent angle) fingers 76 of at least one inclination in abutting connection with intake section 72.Flexible piece 78 makes to be presented bar 64 and is connected with recipient 66.Present bar 64 and preferably have predetermined breakaway poing 80, this point is formed the geometry (for example perforation etc.) of zone that cross section reduces or other caused strain, but but makes by carrying out bending around predetermined breakaway poing 80 or distortion breaking part 84 just can easily be removed breaking part 84 from the tether 62 that can disconnect.

Bar 64 and the flexible piece 78 the most handy flexible materials that can resist water and periodicity illeffects other liquid that may use basically of presenting of the tether 62 that can disconnect are made.Present bar 64 and flexible piece 78 the two preferably all for example acetal or similar material are made with suitable elastomeric polymer.The material of recipient 66 the most handy rigidity basically is metal, timber, glass fibre or plastic production for example.Yet for economic reasons and structurally compatible with flexible piece 78, recipient 66 the most handy acetals are made by injection molding process, but also can utilize other method to make, for example with Plastic Welding or the bonding suitable parts of adhesive.

Preferably adopt can to disconnect tether 62 and tighten mesh pipe 20 and 22, method be at first with flexible piece 78 in practice the habitat of heart point substantially around mesh pipe 20 and 22.To present the intake section that bar 64 passes recipient 66 then it is stretched out from exit portion 74, and tighten around mesh pipe 20 and 22 and can disconnect tether 62.Optionally traction can disconnect tether 62 by recipient 62, contact recipient 66 until inclination finger 76 engagement barbs 68 and shoulder shape brake component 69, so preferably makes and can disconnect tether 62 formation fixed circumference.After shoulder shape brake component 69 contact recipients 66, can stretch, twist or bar 64 is presented in bending, thereby but breaking part 84 is removed from presenting bar 64, make barb 68 still mesh inclination finger 76, as shown in figure 15, and Roughen Edges is retained in the recipient 66 simultaneously.Can guarantee that so just tether 62 does not have possibility to injure ball 36 users' of polymeric web fabric group the edge of a knife or protuberance basically.If presenting the more than one barb 68 of configuration on the bar 64, then tether 62 can be transformed into the fixed circumference of predetermined number, and this predetermined number is corresponding to the number of the barb 68 that is provided.Barb 68 and shoulder brake component 69 preferably are configured in like this to be presented on the bar 64, makes that can disconnect tether 62 binds mesh pipes 20 and at 22 o'clock, and flexible piece 78 still is in the state of stretching, thereby extruding and tighten mesh pipe 20 and 22 forms common center point 32.The finger 76 that tilts preferably meshes barb 68, can prevent to present the direction that bar 64 pours notch portion 72 into along exit portion 74 thus and carry out big moving, thereby keep the extended state of flexible piece 78 basically enduringly.

Another preferred mesh tightening piece is a heating crimping section 86, as shown in figure 16.The formation method of heating crimping section 86 is, with thermal source heating net fabric pipe 20 and 22, makes in the mesh fusing of the accumulation of the virtual center point habitat of mesh, forms permanent basically mesh tightening piece thus.But therefore heat crimping section 86 and be not a kind of can with mesh pipe 20 and the disengaged part of opening in 22 minutes, different with above-mentioned preferred mesh tightening piece 30, but after with the thermal source heating with mesh 20 and 22 formation one, become its part.The thermal source that is used to melt mesh pipe 20 and 22 can be clamping flatiron or roller, a unit for ultrasound sealing etc. electric heating or the heating power heating.
