Background technology

Cotton balls, cotton swab and gauze are widely used in various object.Such as, cotton balls can be used to apply diaper rash ointment, medicament, alcohol, oral anesthestia agent etc.Further, in some cases, cotton balls also can be used to remove all kinds material from human body, such as face cosmetic.In each this type of field, cotton balls or cotton swab are usually made into definite shape special additive or one-tenth to be distributed to and apply region.

But, in some cases, if user want by additive paint such as cotton balls not the not satisfying of generating portion additive drop, may be difficult.Moreover cotton material is usually costly processed with being difficult to compared with other types material.Therefore, need a kind of transmissibility such as medicament and so on additive to the specific improved products applying region at present.Particularly, a kind of finger-stall (finger glove) of energy insulation blocking finger during sending special additive is needed at present.

In addition, another needs the field of the equipment sending additive or composition to be tooth or gum cleaning applications.Tooth needs timing clean to keep oral hygiene.Various membranoid substance and residue, as dental plaque, along with passage of time can be accumulated in tooth and gingival surface, thus cause adverse effect to oral health.In the past, remove this kind of membranoid substance and residue with toothbrush always.Typical traditional toothbrush has two ends, and one end is handle, and the other end is equipped with and is intended to scratch and removes the mane of dental plaque and other residues from cleaned surface.

Although traditional toothbrush is very useful in various occasion, in some cases, they are unsatisfactory.Such as, some individual wishes to keep oral hygiene by brushing teeth at any time whole daytime.Regrettably, many surroundings do not possess the condition encouraging or even allow this kind of behavior.In addition, traveller and those people of working in office environment may to find to use toothbrush daytime inconvenient.Such as, toothbrush is usually not suitable for individual and carries everyday, first because its profile is huge, moreover needs station to hand basin side, washroom.

This to more often doing oral hygiene and the requirement of the cleaning appliance easily used in public for meeting, develop various portable toothbrush.Particularly, develop the dental cleaning that various finger is installed, can be placed on or surround and point and swipe tooth and gum.These apparatus general all very little, be easy to carry and single use.

An example of this kind of disposable tooth cleaning appliance is described in United States Patent (USP) 3,902,509, authorizes the people such as Tundermann.This kind of apparatus high wet strength material that is laminated by such as non-weaving cloth or that be coated with impermeable material and so on is made.Impermeable material can be thermoplastic, such as polypropylene.In addition, the material of various such as spices, bacteriostatic agent, tooth powder (dentrifices) or washing agent and so on can on this apparatus of paint.Use this apparatus, simply it can be enclosed within finger upper and remove food and film of plaque with the mantle friction dental surface of apparatus.

More recently, a kind of similar oral hygiene finger apparatus is disclosed in the United States Patent (USP) 5,445 authorizing the people such as Copelan, in 825.Specifically, this kind of apparatus comprises the sack of protective material, wherein comprises a kind of film.This film such as can be made up of the nonwoven cellulosic pad with schlieren texture embossing.The apparatus that the people such as Copelan describe is dry state, only utilizes the moisture in user oneself mouth.This kind of sack also can be made up of paper tinsel or not moisture-inhibiting slice plastic.

Although this kind of dental cleaning is easy to carry, but usually can not fit snuggly on user's finger in clean period.But, have also been developed some and refer to installation dental cleaning, comprise and clean period apparatus can be prevented relative to user's finger slippage or the elastomeric material that comes off.The example of this kind of dental cleaning is disclosed in United States Patent (USP) 5,068,941, authorizes Dunn; 5,348,153, authorize Cole; 5,524,764, authorize the people such as Kaufman; And PCT publication number WO 95/31154, authorize the people such as Mittiga.Although this kind of elasticity dental cleaning has obvious benefit, these apparatus still exist many-sided not enough.Such as, these apparatus are usually difficult to adopt high speed manufacturing techniques processing, thus certainly will increase production cost.Moreover this kind of apparatus also fully may not be fitted to user's finger and get on, and may cause the allergy of user, also lack aesthetic pleasant outward appearance in some cases.In addition, this kind of apparatus is usually not suitable for applying for cleaning teeth or the various additives otherwise improving oral hygiene.Further, this kind of general both airtight also not moisture-inhibiting of apparatus.

The base web manufacturing finger-stall of the present invention use preferably includes band grain surface, namely the surface of finger-stall contact user's tooth and gum.Residue and membranoid substance can be impelled from the removal tooth and gum with grain surface.The finger-stall that only can be positioned at finger-stall with grain surface will contact the part of tooth and gum or can cover the whole outer surface of finger-stall.In this connection, with reference to figure 3, one embodiment of this invention comprises second segment 30, is made up of the base web comprising band texture non-woven material.When second segment 30 plant thus band texture non-woven material manufacture time, finger-stall 10 can more effectively cleaning teeth or gum.Particularly when finger-stall 10 is set on finger as shown in Figure 1, second segment 30 can be utilized to brush the tooth or gum requiring object.

Forming mode on the nonwoven web used in the present invention with grain surface, can be different with the requirement result of concrete purposes.In embodiment shown in Fig. 3, the nonwoven web in order to manufacture second segment 30 have passed through focus and does not bond, thus forms a large amount of fiber cluster 31.Here used term, a kind of base material once crossed " focus does not bond ", referred to the region comprising protruding non-adhesion area or slight bonding, was around a kind of base material of adhesion area.Such as, as shown in Figure 3, fiber cluster does not bond or slight adhesion area, and they form the many projections protruded from outside nonwoven web surface, thus provide required texture.

It is believed that it is unique for not bonding lapped face by the focus of manufacture of the present invention, and various advantage and benefit are provided, not only in the occasion for finger-stall, and when as other purposes.Such as, see Figure 14, wherein draw the non-jointing material of point caused according to the present invention, be referred to as 76.Except for the manufacture of except finger-stall, it is believed that this kind of material also can be used as grinding-material for various field, comprise for grinding and buffing product, be used as towel, brush etc.The definition of this kind of material is the semi-rigid projection with certain altitude, especially has the height being greater than about 0.02 inch.

In the past, produce the non-adhesive product of various point.Such as, the ring material that non-jointing material is generally used as hook and loop fastener is put.But the material that the past manufactures never makes the projection or fiber cluster 31 that have and have the present invention's height as shown in figure 14.The present inventor not only finds the new method of the non-jointing material of a kind of production, and finds a kind of new product with improvement nonferromagnetic substance.

See Figure 15, wherein draw a kind of embodiment of the method for the non-jointing material of production 76.As shown in the figure, nonwoven substrate 77 is fed into the roll gap formed between the first figure roller 78 and the second smooth roll cylinder 80, is referred to as 82.Base material, once pass through roll gap 82, just forms fiber cluster (fuft) 31.As shown in the figure, fiber cluster 31 region that is bonded, compacting surrounds.

Different according to concrete purposes for the production of the base material 77 putting non-jointing material 76.Such as, base material 77 can be that individual layer maybe can comprise many material layers.In most of occasion, total basic weight of base material 77 should be at least 3osy, especially about 3osy ~ about 9osy.For producing the fiber cluster 31 with suitably height, need higher basic weight.

In most of occasion, base material 77 also should comprise the nonwoven layer that at least one has high thickness/mass ratio.The example with the material of high-loft comprise be made up of polymer fiber or long filament penetrate air bonded web.This nonwoven web can be made up of curling fiber or long filament and/or be made up of the fiber of section and long filament.Such as, crimp bicomponent polyethylene/polypropylene fiber can be adopted.Profiled filament comprises five leaf fibres and doughnut.

Except the non-weaving cloth with high-loft, base material 77 also can comprise film.Such as, in one embodiment, in the production of putting non-jointing material 76, nonwoven web can be combined every wet film.

As shown in figure 15, once after have selected suitable base material 77, then this base material is passed through two roll gap 82.In one embodiment, put non-jointing material 76 to be processed into by heat bonding.Such as, in one embodiment, figure roller 78 and/or smooth roll cylinder 80 can be heated to be enough to melting and clinkering (fuse) base material 77 fiber cluster 31 between the temperature in region.The temperature that roller 78 and 80 is heated to depends on concrete purposes, is especially used for the material of Shaped substrates 77.The temperature that roller is heated to also depends on base material 77 applied pressure size.

In one embodiment, when processing comprises the base material of polyolefine fiber, roller can be heated to the temperature of about 230 °F ~ about 280 °F, especially about 240 °F ~ about 260 °F.Concerning most of purposes, roller 78 and 80 all heats.But figure roller 78 can be heated to above the temperature of roller 80, and vice versa.

When the non-jointing material 76 of production, base material enter roll gap speed, to be applied to the Tensity size on base material and the pressure in roll gap be all produce the key factor needing in this product to optimize.Such as, when adopting the roller of traditional size, the speed that base material passes through roll gap 82 can change to about 100 foot per minute from about 5 foot per minute.

Except heat bonding, also can use the non-jointing material 76 of ultrasonic bonds production.Ultrasonic bonds can adopt stationary apparatus (not shown) or whirligig to implement as shown in figure 15.During ultrasonic bonds, figure roller 78 does and vibrates, to cause the formation of fiber cluster 31.The present inventor finds, the operating efficiency of ultrasonic bonds is higher than heat bonding.Also find out, ultrasonic bonds can process thicker than heat bonding and heavier base material.Such as, ultrasonic bonds can process the base material that basic weight is up to 9osy.Tradition thermal bonding system is but better applicable to the base material that processing basic weight is up to about 5osy.Ultrasonic bonds, compared with traditional heat bonding, also can produce meticulous difference in topographical characteristics.

As mentioned above, the fiber cluster that non-jointing material 76 comprises highly at least 0.02 inch is put.More particularly, the height of fiber cluster will change between about 0.05 inch ~ about 0.1 inch.As shown in figure 15, fiber cluster can have round shape.But will know, fiber cluster 31 can have any suitable shape.Such as, fiber cluster can be square, triangle or even Deep-fried doughnut shape.

The total bond area surrounding fiber cluster 31 also can change with concrete purposes.For most of embodiment, the bond area surrounding fiber cluster can account for about 15% ~ about 40%, especially about 20% ~ about 40% of material surface area.

In a kind of particular of the present invention, put non-jointing material 76 and be made up of two substrate layers.First substrate layer penetrates air bonded web, has the basic weight of 3.25osy.This fibre web can be made up of crimp bicomponent polypropylene, polyethylene fiber.On the other hand, the second base material, be made up of five leaf profiled filaments penetrate air bonded web.Second fibre web also can have the basic weight of about 3.25osy.Two-layer fibre web is side by side fed in roll gap 82, and accepts ultrasonic bonds and produce fiber cluster 31.

In the another kind of alternative embodiment of the present invention, put non-jointing material 76 and be about penetrating between air bonded web and the spunbond fibre web of basic weight 0.5osy of 3.5osy by gas permeability stretching polyethylene film-clamp at basic weight and form.First nonwoven web can be made up of crimp bicomponent fibers, and spunbond fibre web then can be made up of polypropylene filament.

But should understand manufacturing place non-jointing material 76 adopt material and condition can be different along with the difference of the final use of material.
