FEEDER

Technical Field

[1] The present invention relates to a filter device of nursing bottle containing powdered milk, a filter device using magnet and feeder, more particularly, a filter device of nursing bottle containing powdered milk, a filter device using magnet and feeder for powdered milk vessel for completely removing any metallic materials such as iron or aluminum and foreign substances like colon bacillus harmful to human body, which are possibly included in powdered milk. Background Art

[2] Filter device has been a goods widely using in various fields. Therefore, there are many kinds of filter devices distributing in the market, and their respective functions are all different. It is necessary to wisely choose a suitable and good filter device after catching hold of problems through both analysis and testing for specific usage of the filter device for selecting a filter device for safe filtering.

[3] According to recent reports of mass media, there has created a great sensation in our society by detecting foreign substances in both infant formula and goods for baby food. According to the then reports, testing results told that metallic materials comprising iron or aluminum were detected in about 10 products among 33 ones distributing in the market. This is very serious problem, so the present invention is proposed, as charging with infant health with paying a little attention to this issue.

[4] In our country, about 80% of infants are having powdered milk. Moreover, infant formula is a first food that infants have after being brought into the world. Therefore, it must be the cleanest and safest goods. It's because the powdered milk is an essential goods to the infants who cannot have mother's milk.

[5] However, it would be a serious issue, from a parental standpoint who takes care of kids that such reports as foreign substances such as aluminum or colon bacillus like Enterobacter sakazakii in powdered milk and infant's death due to the foreign substances in France or United States, etc. have been continuously raised worldwide as well as our country.

[6] In domestic, a recent report of the National Veterinary Research and Quarantine

Service has given a shock. The report has released that Enterobacter sakazakii is detected as a result of investigation on 33 local and import productions.

[7] The Enterobacter sakazakii, one of colon bacillus, is not a big problem to a person who has immunity. However, it would be fatal if an underweight baby whose weight is less than 2.5 Kg is infected. The symptoms may cause enteritis, blood poisoning at getting in blood and bacterial meningitis at getting to brain. The report also tells that mortality rates are about 10 through 20% if a baby who is less than 1 year old is infected by blood poisoning, and about 20 through 30% in case of bacterial meningitis.

[8] Especially, since the Enterobacter sakazakii has tolerance to some antibiotics, medical treatment would not be easy. In fact, it has not certainly been known about how the Enterobacter sakazakii is infected, therefore, World Health Organization (WHO) and Korea Food & Drug Administration recommends that all powdered milk goods be consumed as fast as possible, while mixing with water having greater temperatures than seventy degrees C, under an assumption of that all powdered milk potentially has Enterobacter sakazakii.

[9] Meanwhile, with respect to non-metallic materials such as carbide getting dark like scorched rice under a dry process of the powdered milk besides the metallic materials like aluminum or iron, there has been endless talks about whether they are harmful or not. It would be a big concern to parents who take care of kids.

[10] Thus, the present invention is proposed for leaching several foreign substances in which are possibly included in the powdered milk, a principal goods of infants, and for having infants safely take the powdered milk by attaching a warning device revealing removal of the Enterobacter sakazakii.

[11] Meanwhile, ideas of using magnet have been since long time ago for medical cure or health improvement. Especially, magnet plaster, magnet necklace, magnet bracelet, magnet pillow and magnet mattress have recently appeared and frequently been used.

[12] Moreover, various health curing methods and curing tools using magnet have appeared. One representative magnet curing model is Transcranial magnetic stimulation or MRI(Magnetic Resonance Imager) known to diagnosis.

Best Mode for Carrying Out the Invention

[63] Preferred embodiments of the present invention will be described below in more detail with reference to the accompanying drawings. Hereinafter, it will be described about an exemplary embodiment of the present invention in conjunction with the accompanying drawings. Like numerals refer to like elements throughout the specification.

[64] Figure 1 is a schematic view of a nursing bottle containing powdered milk comprising a filter device according to an exemplary embodiment of the present invention.

[65] Referring to Fig. 1, the filter device according to the present invention is placed on a nursing bottle containing powdered milk having a vessel body 10 in which comprises a space portion 9 for containing fixed powdered milk and both inner and outer peripheries 11 and 12 at an entrance 30, and a nipple unit 26 to be combined by using both the outer periphery 12 of the entrance and a screw thread to the vessel body 10.

[66] A filter frame 21 of the filter device is placed on along between the outer periphery

12 and the inner periphery 11 of the vessel body. Meanwhile, a diameter of the filter frame 21 is larger than a diameter of a filter 20 so that the filter frame 21 may be place between the inner periphery 11 and the outer periphery 12. The filter frame 21 may be formed in a groove for inner surface of the filter frame 21 so as to be placed on the inner and outer peripheries 11 and 12.

[67] Figure 2 is a plane view of a filter device according to an exemplary embodiment of the present invention. Generally, the particle size of powdered milk is known to either about 25um through 250um or lOum through 250um. Therefore, it is acknowledged that foreign substance having the size of less than 250um may not be removed due to the particle size of the powdered milk.

[68] However, the powdered milk may be changed to colloid state in dissolving itself, while being mixed with water having polarity. The powdered milk may be separated with any foreign substance, even smaller, into a melting state with water. In the powdered milk in colloid state dissolved in water, the largest particle is Casein. The Casein, a principal protein of milk, is included about 2.5 through 3% in the milk or about 1% in mother's milk. The Casein exists as casein calcium in the milk, and is dispersed in particles under colloid state in forming casein calcium or a complex of phosphoric acid calcium by combining with phosphoric acid calcium.

[69] Such particle as known to Casein Micelle may comprise about 95% protein and 5% calcium or inorganic phosphoric acid. The diameter of the Casein Micelle of round shape is known to about 40.3um.

[70] Meanwhile, metallic materials detected in the powdered milk are known to iron and aluminum. As a result of Korean Environment & Merchandise Testing Institute, authorized testing agency of the Korea Food & Drug Administration, the metallic foreign substances are revealed that their size are all larger than about lOOum.The testing result of Korea Research Institute of Analytical Technology has revealed that the size of the foreign substances are about 100 through 150um.

[71] Therefore, referring to Fig. 2, it is important for the pore 23 of the filter 20 to have larger diameter than a diameter of Casein particle, a principal ingredient of powdered milk, in order to effectively leach metallic materials and well have the principal ingredient of the powdered milk.

[72] As illustrated above, the filter device of a nursing bottle containing powdered milk may be essential that the size of the pore 23 should be maintained not to both destroy nutrients of powdered milk and change the composition the powdered milk, but only to leach the foreign substance physically. Moreover, it should be less troublesome for infants to intake the powdered milk dissolving in water passed through the filter content-providing server 20, since the powdered milk dissolving in water speedy passes through the filter.

[73] Generally, in case that the size of the pore 23 is a little smaller, it may be slow to pass powdered milk at passing the filter 20. Therefore, it is important to properly keep the size of the pore 23 for making infants less troublesome in having powdered milk dissolving in water.

[74] Therefore, it is preferable in the present invention for the size of the pore 23 to be about larger than 40.3 um and smaller than about lOOum so that the filter device 20 may perfectly remove any metal materials and safely intake the Casein, the principal ingredient of the powdered milk.

[75] Figure 3 is a front view enlarged a filter device of a nursing bottle containing powdered milk comprising a filter device according to an exemplary embodiment of the present invention.

[76] Referring to Fig. 3, the filter 20 is formed in a round type having a smaller diameter than a diameter of the inner periphery 11 of the entrance 30 in order to tightly seal the vessel body 10. The filter 20 may be implemented in any other shape than the round one. It may be preferable for the filter frame to form its connecting portion between the bottom surface and the side to form a curved line so that the filter is not stained with powdered milk.

[77] Figure 4 is a schematic view of a nursing bottle containing powdered milk comprising a filter device according to other exemplary embodiment of the present invention.

[78] Referring to Fig. 4, a filter device according to another exemplary embodiment of the present invention is a filter device to be placed on a vessel in which comprises a space portion 90 for containing fixed powdered milk and both inner and outer peripheries 110 and 120 at an entrance 300, and a nipple unit 260 to be combined to the vessel 100 by using both the outer periphery 120 of the entrance 300 and a screw thread.

[79] The filter device may doubly and absolutely remove any foreign substance and metallic materials by organizing a filter frame 210 to be placed along between the inner periphery 110 and the outer periphery 120 of the nursing bottle containing powdered milk, at least a magnet 400 to make a single body with the filter frame 210 and the at least a magnet 400 to extend to a space portion 90. The material of the filter frame 210 may be not only metal but also rubber. By the way, it may be preferable to treat the filter frame with silicon coating so that it may not be harmful even touching solution. Moreover, the magnet unit 400 is treated with silicon coating so as not to influence any harmness to the solution of powdered milk containing in the space portion 90.

[80] Meanwhile, there may be a few nursing bottles containing powdered milk among the ones distributing in market in which an inner periphery of a cap for a nipple unit steps down from the entrance 300 of the vessel 100, on the plane. The present invention may cover such nursing bottles containing powdered milk, in order not to interfere with close adhesion.

[81] Meanwhile, there may happen pressures in the nursing bottle, while infants are sucking a nursing bottle, therefore, the filter 200 should bear the pressures. For doing that, the present invention is realized with metallic materials treated by special coating. Therefore, the filter device may be unchangeable in its size of the filter pore 230 and be easily organized for cleaning and control.

[82] Thus, the filter device may easily apply to nursing bottles of various sizes delivering in market without change in particular. Moreover, the filter 200 and filter frame 210 may make a body.

[83] Moreover, the filter frame 210 may be organized to magnetize so that it may leach quite tiny metal materials or foreign substance, if any.

[84] Referring to Fig. 1 through Fig. 4, it is apparent that the filter device of a nursing bottle containing powdered milk according to the present invention may organize to be either easily attached or detached to the vessel body of the nursing bottle containing powdered milk.

[85] Figure 5 is a drawing of a filter device according to another exemplary embodiment of the present invention.

[86] Referring to Fig.5, the filter device may comprise a filter frame 40 with an opening in a center and a filter 45 whose diameter is equal to a diameter of the opened portion of filter frame 40. In the filter device, the filter 45 is placed below the filter device so that users may not touch the filter 45 while using the filter device. Moreover, the filter frame 40 may be jointed with the filter 45 to make a body by using either heat treating or supersonic. The filter 45 according to the present invention is placed below the filter frame 40, but it may be placed in the body of the filter 40.

[87] Figure 6 is a drawing of a filter frame of the filter device of Fig. 5.

[88] Referring to Fig.6, the filter frame 40 has a round shape typed frame 41 having a fixed width, and a body frame 42 formed in perpendicularity below from an outer periphery of the round shape typed frame 41, thereby making a body.

[89] It is preferable that the filter 45 is made in synthetic fiber such as polyester strong to thermotolerance or nylon strong to anti-abrasiveness. Moreover, it may be made in ploy Lactic Acid (PLA) included in environment-friendly corn possible to heat- resistant forming. Moreover, the filter may achieve Bactericidal Effects with silver nano-coating.

[90] Figure 7 is a drawing of a nursing bottle containing powdered milk comprising a filter device according to another exemplary embodiment of the present invention.

[91] Referring to Fig.7, a filter device to be placed on a nursing bottle containing powdered milk 140 having a space portion 139 for containing fixed powdered milk may comprise a filter frame 121 and a filter 120. The filter frame 121 comprise both a round shape typed frame having a fixed width and an opening in a center, and a body frame formed in perpendicularity below along an outer periphery of the round shape typed frame. The filter 120 has pores whose size is about 43 um through lOOum and diameter is equal to a diameter of the body frame. The filter 120 may organize in combining along an inner side of the body frame.

[92] The filter device according to an exemplary embodiment of the present invention may apply to various kinds of bottles containing powdered milk as well as general nursing bottle containing powdered milk. Moreover, those skilled in the art will readily appreciate that the filter device according to an exemplary embodiment of the present invention may apply any bottle containing other materials than powdered milk for filtering.

[93] Figure 8 is a schematic view of a feeder for powdered milk vessel according to still another exemplary embodiment of the present invention.

[94] Referring to fig.8, a feeder for powdered milk according to the present invention may comprise a body unit 310 containing a fixed powdered milk, a lid 320 combining with an upper part of the body unit 310, a filter 325 to be placed on an upper surface of the lid 320 and at least two identifying tags 330 revealing a specific color at a specific temperature on an outer side of the body unit 310.

[95] The body unit 310 may be formed with not only general typed plastic materials, but also plastic materials using cornstarch harmless to human body. Generally, the cornstarch has been spotlighted as environmentally friendly and biodegradable materials. Moreover, as the cornstarch has been widely distributed to ordinary articles, it may be easily achieved. Moreover, the body unit 310 may be achieved to be soft by using silicon.

[96] Meanwhile, it may be necessary to completely remove Enterobacter sakazakii causing fatal to infant in powdered milk contained in the body unit 310, above all thing, as described above. However, it has not known to public to completely remove the Enterobacter sakazakii, yet. Since the Enterobacter sakazakii is sterilized in the range of temperature of seventy (70) degrees, the present invention may confirm that powdered milk would be safe before infant takes it, by attaching tags coating with ink whose color is changed as chameleon by temperatures.

[97] There may be several tags for applying the present invention. It would be possible that color is changed by temperatures. Preferably, two tags may be attached, one for whose color is changeable at the range of temperature of seventy (70) degrees, thereby informing removal of Enterobacter sakazakii and the other for whose color is changeable at the range of temperature of thirty-five (35) degrees, thereby informing the best timing for drinking. As an example of such a tag, thermochromic pigment may be coated, but not to be construed as limiting thereof.

[98] In addition, it may be attach another tag changing color at a non-suitable temperature for taking, for example, the temperature of ten(lθ) degrees or below, so that it may be easily detected whether they can have the powdered milk.

[99] Moreover, the present invention may easily detect the change of temperature of the powdered milk containing in the body unit 310 by attaching a tag 330a changing its color at relatively low temperature on an upper surface of the body unit 310. Meanwhile, as an alternative of the tags 330, material such as paper thermometer may also be attached on the outer surface of the body unit 310.

[100] Moreover, since an end of an upper portion of the body unit gets bent and slopes down in a feeder for powdered milk 300 according to an exemplary embodiment of the present invention in order to easily pour into a powdered milk baby bottle, it may prevent any loss of powdered milk from flowing down, while the powdered milk is poured into the powdered milk baby bottle with completely inverting the feeder. It shows in the Figures that an end of an upper portion of the body unit 300 gets bent, but it may be possible for the lid 320 to get bent instead of the body unit 310.

[101] Figure 9 is a schematic view of a lid of Fig. 8.

[102] As shown in the Figure, a lid 320 may be a round typed shape of being get bent to a slant position by narrowing a upper surface 321 compared to a bottom surface 323. And, the inside of the upper surface 321 may be completely covered by a filter 325. The lid 320 may be unified with the body unit 310 by forming screws in both the inside of the lid 320 and the body unit 310, or tightly holding into the body unit 310 by using elasticity of the body unit 310.

[103] Moreover, the filter may redouble antimicrobial and bactericidal effects by coating its upper portion with silver nano of antimicrobial material.

[104] Figure 10 is a view of a filter of Fig. 8.

[105] As shown in the Figure, a filter 325 according to an exemplary embodiment of the present invention may comprise a plurality of pores 331 forming a latticed shape. The pores 331 of the filter 325 may have a larger diameter than the Casein particle in order to both effectively leach metal ingredient or foreign substance of carbide and smoothly pass the Casein, a principal ingredient. Therefore, the present invention is organized in that the size of the pores 331 is about 43 um through lOOum. Preferably, the diameter of the pores 331 may keep within the range of about 53um through lOOum.

[106] Figure 11 is a schematic view of Fig. 8 with a bottom cap.

[107] As shown in the Figure, a feeder for powdered milk may comprise a body unit 310 containing a fixed powdered milk, a lid 320 of round typed shape attaching a filter 325 on an upper part of the body unit 310 to cover the upper part of the body unit 310, at least two tags 330 revealing a specific color at a specific temperature on an outer side of the body unit 310 and a bottom cap 340 for attaching on a lower part of the body unit.

[108] Since the body unit 310 may form a hole 350 in the center of its bottom surface in order to clean its inside to detail, users may clean with a cleaning tool such as a brush through the bottom surface. The bottom cap 340 may form to be tightly held with the body unit 310, while plugging the holes 350. Moreover, the body unit 310 may be implemented by soft silicon as well as plastic for easy handling.

[109] Thus, a feeder for powdered milk according to an exemplary embodiment of the present invention gets rid of the concerns for the continuing social issue of possible several foreign substances in powdered milk so that infants may safely have powdered milk favorable to their health. It may also apply to baby bottles of various kinds of size.

[110] Figure 12 is a plane view of a filter device according to still another exemplary embodiment of the present invention.

[I l l] Referring to Fig. 12, it shows that a silicon unit 510 strong to adhesion wraps some parts of a filter device from an outer periphery of a magnet unit 520 toward midpoint. Especially, it shows a shape that an outer periphery of the magnet unit 520 does not overlap with the silicon unit 510, thereby easy handling at either attaching or detaching the silicon unit to the side of a vessel 530, after closely contacting the magnet unit 520 beneath the bottom surface of the vessel 530.

[112] The silicon unit 1 wraps the magnet 520 in an exemplary embodiment of the present invention. However, it may be good to use a rubber material having both good adhesion and elasticity enough to either attach or detach to the vessel 530.

[113] Figure 13 is a schematic view of a magnet unit of Fig. 12.

[114] Referring to Fig.13, it shows that the magnet unit 520 is a cylindrical shape.

However, it may not be construed as limiting thereof, but be implemented in rectangular or triangular shape. The silicon unit 1 must effectively wrap the magnet unit 520.

[115] Figure 14 is a plane view of a nursing bottle containing powdered milk comprising a filter device of Fig. 12.

[116] Referring to Fig.14, it shows that the silicon unit 510 wraps some parts of the magnet unit from the bottom surface of the vessel 530.

[117] Iron included in powdered milk is a certain nutrient for infants. However, the iron may exert a bad influence on infants because the iron accumulates in their body due to their weak digestion capability, in case that they have iron having large particles continuously. As a result of Korean Environment & Merchandise Testing Institute, authorized testing agency of the Korea Food & Drug Administration, Iron of the foreign substance, is revealed that its size is all larger than about lOOum.The testing result of Korea Research Institute of Analytical Technology has revealed that the size of the foreign substance is about 100 through 150um. Therefore, the iron particles may not easily be removed with general typed filter since the particle size is too small.

[118] An exemplary embodiment of the present invention, as shown in Fig. 14, may easily attach the filter device, if they pushes the silicon unit 510 overlapping with the magnet unit 520 to side of the vessel 530 from the bottom surface of the vessel 530. Thus, the filter device is very safe and sanitary because any metal ingredients like iron included in the vessel 530 move to the filter device so that infants may have purified powdered milk.

[119] Meanwhile, since magnet has lots of merits favorable to human body, the usefulness of the magnet may be easily enjoyed through the present invention.

[120] The filter device according to an exemplary embodiment of the present invention applies to a baby bottle containing powdered milk in Fig. 14. It may also easily apply to other vessels having various sizes widely distributing in the market, without any modification.

[121] The filter device according to an exemplary embodiment of the present invention is never separated while using the filter device, since the silicon unit 510 completely wraps the magnet unit 520.
