Description

Description BABY FEED BOTTLES WITH FLEXIBILITY

Technical Field

[1] The present invention relates to a baby feed bottle, and more particularly, to a baby feed bottle with flexibility configured to include a baby bottle body with flexibility enabling elastic deformation and a teat coupled to an upper part of the baby bottle body such that the baby bottle body and the teat are directly coupled with each other with no interposition of other components, thus making nonuse of parts such as separate support or cap, thereby facilitating asserrbly and disassembly, minimizing a feeder's inconvenience of use and in addition, preventing generation of an environmental hormone. Background Art

[2] In general, baby feed bottles are used when feeders intend to feed powdered milk in place of mother's milk to newborn babies or infants/babies. The baby feed bottle is configured to couple a teat cap fixing a teat to a plastic-container shaped baby bottle body containing powdered milk liquid so that babies can suck the powdered milk liquid through the teat.

[3] The baby bottle body is mainly made of plastic materials with less weight or is made of glass materials with excellent safety. Disclosure of Invention Technical Problem

[4] However, the conventional baby bottle body as above has the following drawbacks.

[5] First, there is a drawback that if the baby bottle body is formed of plastic materials, it generates environmental hormone Bisphenol A. Particularly, the environmental hormone is increasingly generated in amount when the baby bottle body gets in contact with hot water. Thus, there is a drawback that the environmental hormone is remarkably increasingly generated in amount if hot water is filled and is mixed with powdered milk in the baby bottle body, or if powdered milk is warmly retained in the baby bottle body for a long time as dissolved in water, or if the baby bottle body is sterilized with hot water for a long time.

[6] Second, even if the baby bottle body is made of plastic materials such as polycarbonate with less environmental hormone, its frequent washing causes generation of foreign abrasive materials as well as giving out of plastic's own odor. If the baby bottle body is made of glass materials, it can prevent generation of environmental hormone but increases the danger of easy destruction. If the baby bottle body is made thick for durability increase, it increases a self-weight of the baby bottle and therefore, it is very difficult for an infant to have powdered milk with holding a baby bottle up. If the baby bottle falls in a high position or if a child drops the baby bottle while going around because of the characteristics of child's inattention, the baby bottle is in the danger of destruction and thus, additionally generates the danger of wound due to broken glass fragments.

[7] Third, if the baby bottle body is made of hard materials such as plastic or glass, its internal powdered milk liquid decreases and its internal atmospheric pressure decreases while an infant sucks a teat, thus resulting in a vacuum effect. Therefore, there is a drawback that an infant requires a very large inhalation force, suffers otitis media in a worse case because of a low atmospheric pressure within the mouth, and inhales much air when inhaling external air along with powdered milk liquid due to his inhalation trouble, thus suffering stomach trouble or suffering frequent burp.

[8] Fourth, there has been proposed a method for changing a structure of a baby bottle body or processing an air inlet into part of a teat to prevent a reduction of an atmospheric pressure within the baby bottle body. However, the method has a drawback that a baby bottle structure gets complex, post-use washing is difficult, an additional manufacturing cost rises, and a vacuum effect is not solved completely.

[9] Fifth, in order to provide a solution to the above drawback, there has been proposed a method for making a baby bottle body using flexible materials or pliable sili<x>n materials. However, the method has a drawback that because a support structure of separate plastic or metallic materials is used to secure coupling of the baby bottle body and the teat cap, asserrbly and disasserrbly is incDnvenient due to an increase of the number of parts. Further, the method has a drawback that if the support structure is simply forcibly inserted to an upper end of the baby bottle body, the characteristic of silicon materials having high viscosity makes asserrbly very difficult because of viscosity between the baby bottle body and the support structure. Furthermore, the method has a drawback that because the support structure is of plastic materials, a baby bottle should be separated into plastic class and silicon class and sterilized one by one due to a problem that the baby bottle is exposed to environmental hormone when a feeder boils and sterilizes the baby bottle together without separation. Technical Solution

[10] The present invention includes a container shaped baby bottle body having a joint part providing an input opening and formed at its upper part integrally with the body, and having flexibility enabling elastic deformation,

[11] a teat coupled to an upper part of the baby bottle body, and having a feeding part at its upper side part and having a coupling part formed at its lower side part integrally with the feeding part such that it is ooupled corresponding to the joint part.

Advantageous Effects

[12] Accordingly, the present invention can provide an available scheme of a silicon baby bottle and thus prevent infant exposure to environmental hormone, by forming the baby bottle body using materials such as silicon with flexibility enabling elastic deformation as described above. Further, the present invention can minimize the nurrber of parts and more conveniently assemble or disassemble the baby bottle and can minimize a feeder or infant's inconvenience of use, by directly coupling the baby bottle body with the teat without a separate support structure.

[13] Further, the present invention can feed an infant in a more stable emotion state and in addition, minimize silicon viscosity, thus achieving simple and convenient asserrbly and disassembly, by adding the rugged part similar with a human's skin to the baby bottle body and realize an effect that an infant actually feels the mother body with hands.

[14] Furthermore, the present invention has a convenience that a feeder does not need to separately separate and boil a plastic product such as a baby bottle cap when sterilizing a baby bottle by excluding the use of environmental-hormone induced materials. Brief Description of Drawings

[26] Hereinafter, the present invention will be described in detail with reference to accompanying drawings.

[27] FIG. 1 is a coupling cross section of an exemplary embodiment of the present invention.

[28] As shown, the present invention includes a baby bottle body 10 and a teat 40.

[29] The baby bottle body 10 is to contain powdered milk liquid inside. The baby bottle body 10 is of a cylindrical container shape the internal of which is hollow and a top of which is opened. A joint part 20 is formed at an upper part of the baby bottle body 10 and provides an input opening 15 having a smaller diameter than the baby bottle body 10.

[30] The baby bottle body 10 is formed of transparent or semitransparent resin with flexibility enabling elastic deformation. The baby bottle body 10 can be of materials such as silicon, natural rubber, polyethylene (FE), polyurefhane, etc. Mare desirably, the baby bottle body 10 is of silicon materials doing no harm to a human body.

[31] The joint part 20 is molded integrally with the baby bottle body 10 and is formed relatively thicker than the body such that it can support the teat 40 more firmly.

[32] The joint part 20 is formed to have a predetermined thickness along a periphery such that the input opening 15 is formed at an upper part of the baby bottle body 10. The joint part 20 has an insertion recess 25 of a predetermined depth at its inner periphery. Catching protrusions 26 are formed to protrude inside and face each other at upper and lower sides of a front-end part of the insertion recess 25.

[33] The teat 40 includes a feeding part 45 and the coupling part 30.

[34] The teat 40 is of a shape the internal of which is hollow and a bottom of which is opened. The feeding part 45 is formed at an upper part of the teat 40 and discharges powdered milk liquid contained within the baby bottle body 10. The coupling part 30 is formed at a lower part of the teat 40 and is coupled to the joint part 20 of the baby bottle body 10. [35] The coupling part 30 is formed integrally with the feeding part 45. The coupling part

30 is formed relatively thicker than the feeding part 45 such that it can be coupled with the joint part 20 more firmly.

[36] The coupling part 30 is formed correspondingly such that its outer periphery can be adhered to an inner periphery of the joint part 20. A protrusion rib 35 is formed around and at the outer periphery of the coupling part 30 such that it can be shape-matched and coupled to the insertion recess 25.

[37] The protrusion rib 35 has catching recesses 36 corresponding to the catching protrusions 26 at its upper and lower sides, respectively, such that the protrusion rib 35 is not unintentionally released from the insertion recess 25.

[38] Coupling of the baby bottle body 10 and the teat 40 is achieved by pressing and deforming the coupling part 30 in a center direction, then inserting the coupling part 30 to the joint part 20 through the input opening 15 of the baby bottle body 10, and then pressing the coupling part 20 such that the protrusion rib 35 of the coupling part 20 is pressed in and inserted into the insertion recess 25 of the joint part 20.

[39] Thus, because the baby bottle body 10 and the teat 40 do not require a process of asserrbling a separate support structure or a cap fixing the teat 40, they can be asserrbled and disassembled rapidly and simply and conveniently.

[40] A shape-matched section of the joint part 20 of the baby bottle body 10 and the coupling part 30 of the teat 40 is of a protrusion shape, a recess shape, or a oorrbination thereof of a curved line, a straight line, or a conϋnation thereof and thus, the joint part 20 and the coupling part 30 can be constructed in various types.

[41] That is, an inner periphery of the joint part 20 of the baby bottle body 10 can be of various shapes such as a protrusion shape, a recess shape, or a combination thereof consisting of a 'C shape, a rugged shape or a corrbination thereof. An outer periphery of the coupling part 30 of the teat 40 is of a protrusion shape or a recess shape such that it can be shape-matched corresponding to the inner periphery of the joint part 20, thus enabling coupling of various ways.

[42] The teat 40 is formed of silicon.

[43] Thus, in the present invention, powdered milk liquid filled in the baby bottle body 10 comes into contact with only the baby bottle body 10 and the teat 40 made of silicon. Thus, infant's feeding surroundings can be maintained with environmental hormone completely cut off.

[44] The baby bottle body 10 uses materials of a proper hardness and keeps optimal flexibility, thus realizing a sensation as if an infant felt the mother body with hands when being fed.

[45] If using siliαon materials exceeding a proper hardness, the baby bottle body 10 is too solid and thus makes it difficult for an infant to suffer a sensation as if he felt the mother body with his hands. If hardness is too low, the baby bottle body 10 is difficult to maintain its own shape because of undue flexibility and also, can strongly jet powdered milk liquid because being easily pressed by infant's hands.

[46] Accordingly, in order to avoid the above drawback, the baby bottle body 10 needs to maintain a proper hardness. Desirably, the baby bottle body 10 uses materials having a proper hardness value within a range of 40 to 50 based on Shore A.

[47] If the baby bottle body 10 is made of siliαon, its interfaάal energy is low and viscosity is high more than needed because of the characteristic of silicon materials. Thus, it causes an additional drawback of making it difficult for an infant to feel the same tactile sensation as that of a human skin. Therefore, it is desirable that a viscosity prevention function is additionally applied to surfaces to decrease vis∞sity. The visoosity prevention function is a method for forming a rugged part 16 of a specific shape at a surface and a method of processing a surface by slip-oaating.

[48] The rugged part 16 is formed at part or all of an outer periphery of the baby bottle body 10. The rugged part 16 can be formed in various shapes such as a circle, a dotted line, a polygonal shape, a mesh shape, a straight-line recess, a random structure, or a oonϋnation thereof. Desirably, a size of each unit constituting the rugged part 16 is realized less than a few hundreds to a few dozens of micrometers considering washability and tactile sensation.

[49] According to the inventors' experiment result, it was reported that viscosity disappears definitely when the rugged part 16 has a size of less than the maximum 500 micrometers on the basis of an outermost size.

[50] FIG. 2 shows an exemplary errbodiment of the rugged part 16. The rugged part 16 can be formed protrusively to have a circular shape as shown in FIG. 2A or can be also formed protrusively to have a rectangular shape as shown in FIG. 2B.

[51] The rugged part 16 can be formed in a lattice scale shape as shown in FIG. 2C or can be formed to have a plurality of straight lines spaced a predetermined distance apart as shown in FIG. 2D.

[52] The rugged part 16 can be realized at a metal mold in a fine pattern etching or sanding method, etc. The rugged part 16 can be formed integrally by an injection molding of the baby bottle body 10. Alternately, the rugged part 16 can be formed in a method of manufacturing and then processing the baby bottle body 10 by etching or sanding.

[53] Slip mating is a method for αoating a silicon surface with separate materials and removing viscosity of a surface of the baby bottle body 10 for easy slip generation. It is possible to provide the slip coating in a printing or spraying method using metal materials, ceramic materials, silicon compounds, organic materials, other organic/ inorganic mixture materials, etc. doing no harm to a human body.

[54] The viscosity prevention function is added in positions of all or part of an outer periphery of the baby bottle body 10. Particularly, it is desirable that the viscosity prevention function is disposed in a position where an infant catches the baby bottle body 10 with hands.

[55] Also, the viscosity prevention function can be provided even to the joint part 20 and the coupling part 30 such that the baby bottle body 10 and the teat 40 are easily asserrbled.

[56] Meantime, the rugged part 16 and the slip αoating are also identically applicable to other exemplary embodiment of the present invention.

[57] Accordingly, the present invention can provide an available scheme of a silicon baby bottle and thus prevent infant exposure to environmental hormone, by forming the baby bottle body 10 using materials such as silicon with flexibility enabling elastic deformation as described above. Further, the present invention can minimize the nurrber of parts and more conveniently assemble or disasserrble the baby bottle and can minimize a feeder or infant's inconvenience of use, by directly coupling the baby bottle body 10 with the teat 40 without a separate support structure.

[58] Further, the present invention can feed an infant in a more stable emotion state and in addition, minimize silicon viscosity, thus achieving simple and convenient asserrbly and disassembly, by adding the rugged part 16 similar with a human's skin to the baby bottle body 10 and realize an effect that an infant actually feels the mother body with hands.

[59] Furthermore, the present invention has a convenience that a feeder does not need to separately separate and boil a plastic product such as a baby bottle cap when sterilizing a baby bottle by excluding the use of environmental-hormone induced materials. Mode for the Invention

[60] Other exemplary errbodiments of the present invention will be described in detail with reference to FIGS. 3 to 11.

[61] FIGS. 3 to 7 are to modify a coupling structure such that a baby bottle body and a teat can be ooupled more simply and conveniently. FIGS. 3 to 7 show the same con- struction as that of the present invention described above except for a modified construction. Thus, only the modified construction is described.

[62] FIGS. 3 and 4 show that a teat 40a is pressed in and αoupled to an upper part of the baby bottle body 10a. An insertion recess 25a of a predetermined depth is provided at an inner periphery of a joint part 20a of the baby bottle body 10a. A slant surface 27a inclining downward in a center direction is formed at a lower side of a front-end part of the insertion recess 25a.

[63] A coupling part 30a of the teat 40a is formed such that its outer periphery corresponds to the inner periphery of the joint part 20a. A protrusion rib 35a is formed along and at a lower side part of the outer periphery such that it can be inserted into the insertion recess 25a.

[64] A slide surface 37a is formed on the slant at a lower side surface of the protrusion rib

35a such that it corresponds to the slant surface 27a of the insertion recess 25a.

[65] Thus, coupling of the baby bottle body 10a and the teat 40a is achieved by inserting the coupling part 35a inside the joint part 20a providing an input opening 15 of the baby bottle body 10a and then, again pulling the teat 40a up such that the slide surface 37a comes into contact with the slant surface 27a while the protrusion rib 35a is inserted into the insertion recess 25a.

[66] Accordingly, the teat 40a and the baby bottle body 10a are coupled more simply and conveniently.

[67] FIG. 5 shows that screw threads are formed corresponding to each other at an inner periphery of a joint part 20b of a baby bottle body 10b and an outer periphery of a coupling part 30b provided below a feeding part 45b of a teat 40b. The teat 40b is screw-engaged to the baby bottle body 10b simply and conveniently.

[68] FIGS. 6 and 7 show that a coupling part 30c of a teat 40c covers while being coupled with a joint part 20c of a baby bottle body 10c. FIG. 6 shows a hoist-up state of a skirt part 35c and FIG. 7 shows a coupling state.

[69] As shown, a protrusion rib 25c of a predetermined height is formed along an outer periphery of the joint part 20c. The skirt part 35c is formed at a lower side part of the coupling part 30c to elastically cover the outer periphery of the joint part 20c.

[70] Desirably, an inner periphery of the skirt part 35c is formed to have a smaller diameter than the outer periphery of the joint part 20c. A curved part 38c is formed at the inner periphery of the skirt part 35c such that the curved part 38c can adhere to and cover the protrusion rib 25c of the joint part 20c.

[71] Thus, coupling of the baby bottle body 10c and the teat 40c is achieved, as shown in FIG. 6, by hoisting up and expanding the skirt part 30c of the teat 40c outside and then, again repositioning the skirt part 30c such that the outer periphery of the joint part 20c is covered.

[72] Accordingly, the teat 40c is more firmly coupled by allowing the skirt part 35c to elastically adhere to and cover the outer periphery of the joint part 20c.

[73] FIG. 8 shows an exemplary errbodiment in which a support ring 60, 61, 62, 63, or 64 is installed in at least one of a joint part 20, 20a, 20b, or 20c or a coupling part 30, 30a, 30b, or 30c such that ooupling of a baby bottle body 10, 10a, 10b, or 10c and a teat 40, 40a, 40b, or 40c can be more firmly adhered. As shown in FIGS. 8A and 8D, the support rings 60 and 61 are formed to have elliptical sections and are installed in the joint parts 20c and 20b. Alternately, as shown in FIG. 8B, the support rings 62 and 63 each can be also installed in the joint part 20a and the ooupling part 30a. As shown in FIG. 8C, the support ring 64 can be also installed only in the joint part 20.

[74] FIGS. 9 and 10 show that partial cross sections of further another exemplary embodiments of the present invention. In FIG. 9A, a ooupling part 30b of a teat 40b and a joint part 20b of a baby bottle body 10b are screw-engaged. A support ring 65 is further provided at a support recess 22b provided at an outer periphery of the joint part 20b to increase adherence and provide more firm ooupling.

[75] As shown in FIG. 9B, a support recess 12a is provided at an outer periphery of a joint part 20a of a baby bottle boy 10a. A support ring 67 can be also provided at the support recess 12a.

[76] The support ring 65 and 67 are also applicable to other exemplary embodiments of the present invention.

[77] In FIG. 10, a support recess 22d is provided at an outer periphery of a joint part 2Od.

A support ring 66 is inserted and installed in the support recess 22d. A catching recess 24d is provided at an upper part of an inner periphery of the joint part 2Od.

[78] An outer periphery of a ooupling part 30d of a teat 4Od is formed correspondingly such that it is adhered to the inner periphery of the joint part 2Od. A catching protrusion 34d is formed along and at an upper part of the outer periphery of ooupling part 30d such that it is shape-matched corresponding to the catching recess 24d. A wing part 35d is formed at a lower side of the catching protrusion 34d.

[79] The wing part 35d is protruded and formed to have a small thickness enough to facilitate deformation and can be arranged and installed in plural in an up/down direction.

[80] A support rib 32d is formed along and at an upper side of an outer periphery of a coupling part 30d to prevent the coupling part 30d from being inserted into a baby bottle body 1Od deeper than needed.

[81] Thus, coupling of the teat 4Od and the baby bottle body 1Od is achieved by inserting the coupling part 30d of the teat 4Od inside the joint part 2Od.

[82] At this time, the catching protrusion 34d is inserted into the catching recess 24d and the wing part 35d is deformed upward and adhered to the inner periphery of the joint part 2Od, thereby making the baby bottle body 1Od airtight more firmly. A lower side surface of the support rib 32d is adhered to an upper surface of the joint part 2Od and thus, the teat 4Od is supported.

[83] The support ring 66 is to support the joint part 2Od and make coupling more firm.

Like an exemplary errbodiment of the present invention of FIG. 8, the support ring 66 can be also installed in at least one of the joint part 2Od and the coupling part 30d.

[84] The support rings 60, 61, 62, 63, 64, 65, 66, and 67 can use metal, ceramic, or plastic materials and can be formed to have cross sections of various forms such as a circular shape, a rectangular shape, and an elliptical shape. At the time of molding, the baby bottle bodies 10, 10a, 10b, 10c, and 1Od can be manufactured in an in-mold way by performing an injection or press work in a state where the support rings 60, 61, 62, 63, 64, 65, 66, and 67 are installed in a metal mold.

[85] FIG. 11 shows a perspective view illustrating the support ring 65 provided in the exemplary errbodiment of FIG. 9. As shown in FIG. 1 IA, the support ring 65 is formed to have a circular shape. Alternately, as shown in FIG. 1 IB, a cutaway part 68 can be also formed in part of the support ring 65 to facilitate asserrbly and enable elastic deformation.

[86] The cutaway part 68 is identically applicable to the support rings 60, 61, 62, 63, 64,

66, and 67 of other exemplary errbodiments. Industrial Applicability
