Detailed Description
The embodiments described below are preferred embodiments of the present invention, and various limitations that are technically preferable are added thereto. However, this preferred embodiment is not intended to limit the present invention; but equivalent variations can be obtained in accordance with the foregoing description; all should belong to the protection scope of the utility model.
Fig. 1 is a schematic front view showing a structure of a nursing bottle according to an embodiment of the present invention; in the figure, a bottle 1 is used as a feeding bottle or the like, and is an example of a beverage container. An external thread (not shown) is formed on the outer circumference of the upper end of the bottle 1 to be capable of being engaged with the internal thread of the inner surface of the cap 2. The cap 2 is embedded with the lower base of the nipple 3, and in this state, the cap 2 is screw-coupled to the upper end of the bottle 1 to form a stable structure.
As shown in fig. 2, a cap 2 is provided opposite the bottle 1 for mounting a nipple 3. The entire lid 2 is a molded article of hard synthetic resin, and is a flat cylindrical body. The upper opening 21 of the flat cylindrical body is smaller in diameter than the lower opening 22, and a female screw 23 is formed on the inner surface of the flat cylindrical body. An inward flange portion 24 is formed on the upper portion of the lid 2 adjacent to the upper opening 21.
as shown in fig. 3 and 4, the nipple 3 is composed of two materials with different hardness, namely a soft part 30 and a hard part 31. The soft portion 30 shown in the nipple 3 is integrally molded with an elastic material such as a soft synthetic resin. As such a material, silicone rubber, isoprene rubber, thermoplastic elastomer or natural rubber having a hardness of 5 to 30 (measured by Shore A durometer, hereinafter all the hardness are referred to as "hardness" in the present application) is used. In the present embodiment, the silicone rubber is selected so that the hardness can be set to 5 to 30. The soft portion 30 shown in fig. 4 is designed to be soft silicone rubber, preferably with a hardness of 5 to 30 degrees, at the nipple portion 33 and other outer surface layers, so as to achieve a soft and comfortable mouthfeel. In the present application, the hardness of the soft portion 30 may be selected to be 15 degrees.
The hard portion 31 shown in the nipple 3 is integrally molded with an elastic material such as a soft synthetic resin having a relatively high hardness (with respect to the soft portion 30). As such a material, silicone rubber, isoprene rubber, thermoplastic elastomer or natural rubber having a hardness of 30 to 80 is used. In the present embodiment, the silicone rubber is selected so that the hardness can be set to 30 to 80. The hard portion 31 shown in fig. 4 is made of a relatively hard silicone rubber, and is designed on the inner layer of the nipple ring portion and the lower layer of the nipple base ring (i.e., the rest portions except the nipple portion 33 and other outer surface layers, and the air return valve 51 described later). The preferred hardness is 30-80 degrees; the hard portion 31 serves as a support to prevent collapse due to large negative pressure generated when a user strongly sucks the liquid for a short time. In the present application, the hardness of the hard portion 31 may be selected to be 50 degrees.
The nipple 3 is a hollow molded article having a substantially conical shape as a whole, and is formed of the materials of the soft portion 30 and the hard portion 31. The nipple 3 has: a base portion 35 having an enlarged diameter corresponding to an attachment object (e.g., an opening portion of the bottle 1 in fig. 1); a nipple ring portion 34 formed continuously with the base portion 35 and extending so as to gradually decrease in diameter; and a nipple portion 33 which extends from the nipple ring portion 34, is not enlarged in diameter until reaching the tip end, and is gradually reduced in diameter and extends at a diameter reduction ratio smaller than that of the nipple ring portion 34.
A nipple part top 32 for flowing out beverage is formed at the upper end of the nipple 3, and a plurality of radial notches of a circular ring shape can be adopted in the nipple part top 32. When the nipple head is squeezed and sucked in the mouth of the infant, the annular incision is opened, milk flows out like breast milk in a radial shape like a breast gland, and cannot be directly sprayed to the throat of the infant, so that the milk choking probability can be effectively reduced. When the nipple top part 32 of the nipple 3 is not squeezed and sucked in the baby's mouth, the ring-shaped incision is closed, and the flow is automatically locked to prevent milk choking. In the present embodiment, the nipple tip 32 is designed to have a thin wall thickness, preferably 0.4 to 1.2mm, so that the incision of the nipple tip 32 is easily opened during the squeeze sucking. In this application, the nipple top 32 wall thickness design is 0.6 ~ 0.8 mm.
In one embodiment of the present application, the nipple portion top 32, the nipple portion 33, the outer layer of the nipple ring portion 34, and the outer layer of the base portion 35 of the nipple are made of the soft portion 30 with lower hardness; the hard portion 31 having a high hardness is used as the inner layer of the nipple ring portion 34 and the inner layer of the base portion 35.
In the present application, the nipple ring portion 34 has a thicker wall thickness at the boundary with the nipple portion 33, and the nipple ring portion 34 is thicker than the nipple portion 33 and is formed as a band-shaped step along the circumference of the position, that is, the connection portion 37. As shown in fig. 4, the connecting portion 37 is configured to gradually change the wall thickness such that the wall thickness becomes thinner in the vicinity of the nipple portion 34 and the wall thickness becomes thickest in the vicinity of the nipple portion 33. This increases the rigidity of the connecting portion 37 near the nipple ring portion 34, and decreases the rigidity when approaching the nipple portion 33, thereby making the mouthpiece portion soft to the touch. However, since the hardness of the inner layer material is high at a position near the nipple ring portion 34, a structure in which dent is less likely to occur at the time of squeeze sucking is formed, and the inner layer material is less likely to collapse at the time of large negative pressure generation at the time of large sucking.
The wall thicknesses of the nipple ring portion 34 and the nipple portion 33 can be appropriately adjusted based on the hardness of the material used, but it is preferable that the wall thickness of the nipple portion 33 is 0.5 to 3.5mm and the wall thickness of the nipple ring portion 34 is 2.0 to 5.0 mm. In the present embodiment, the average wall thickness of the nipple portion 33 is set to 2.0mm, and the average wall thickness of the nipple ring portion 34 is set to 3.5 mm.
The nursing nest in the oral cavity of the infant is usually located at a position which is about 15mm from the lip of the infant to enter the oral cavity. For this reason, in order to make the nipple portion 33 reach a sufficient length of the nursing nest in the oral cavity of the infant; as shown in fig. 4, the length-directional dimension L2 of the mouthpiece section 33 is set to: when nursing (hereinafter, also referred to as "nursing") is performed, the length L2 of the nipple portion 33 is 15mm or more so that the tip of the nipple portion 33 can reliably reach the nursing nest of an infant. In the present embodiment, the length of the nipple portion 33 in the longitudinal direction is 22mm, and the length L1 from the lower end of the base portion 35 to the tip of the nipple portion top portion 32 is 39 mm. In addition, the nipple ring part 34 is not inserted into the oral cavity of the infant even if the infant expands the lips during nursing, and the lips of the infant can be stably held; preferably, the width of the base 35 in the radial direction is 35mm or more. In the present embodiment, the width of the base 35 in the radial direction is set to 38 mm. Due to the larger arc of the nipple ring part 34, the nipple part 33 can be prevented from extending into the mouth of the newborn too much and exceeding the position of the nursing nest to cause discomfort or milk choking of the newborn. The arc surface is closer to breast milk sense and can play a role in protecting newborn babies.
The lower part of the base 35 of the nipple 3 forms a fixing ring 39; the base part 35 is smoothly connected with the fixing ring 39 in an arc manner, and the maximum diameter of the base part 35 is preferably 2-10 mm larger than the diameter of the fixing ring 39. In the present embodiment, the base 35 is larger than the fixing ring 39 by 3 mm. The flexible interference fit is convenient to use and assemble, the nipple 3 can be easily assembled on the bottle cap 2 from the lower part of the bottle cap as shown in the figure 2a by means of a clamp and other tools, and secondary pollution is avoided when the nipple is assembled by hands after disinfection.
As described above, according to the present embodiment, the nipple 3 includes the nipple ring portion 34 which is formed continuously with the base portion 35 and extends so as to gradually decrease in diameter, and the nipple portion 33 which extends from the nipple ring portion 34, is not expanded in diameter in the middle before reaching the distal end, and gradually decreases in diameter at a diameter decrease rate smaller than that of the nipple ring portion 34. Moreover, the nipple part 33 is set to be a sufficient length that the nipple part 33 can reach the nursing nest in the oral cavity of the infant when nursing, and the nipple part 33 can safely reach the oral cavity of the newborn through the special design of the nipple ring part 34, so that the nipple part can not extend too long to cause discomfort or milk choking of the infant; the wall thickness of the top 32 of the nipple part is designed to be thin, so that a newborn can easily suck milk; the design of the breast milk mammary gland ring incision imitating the nipple part top 32 can automatically lock the flow and prevent milk from being choked. Through the design of two materials of different hardness for nipple portion 33 is soft easily to inhale, and nipple ring portion 34 holding power is stronger. Through the shape and the assembly size design of the nipple base part 35, the nipple is convenient to assemble by using tools such as a clamp and the like, and secondary pollution is avoided.
as shown in fig. 4, 9 and 10, the nipple base 35 of the nipple 3 has: a bulge portion 41 bulging outward in the diameter direction over the entire circumference at a lower portion of the nipple ring portion 34; an overhang portion 36 and a flange portion 38 formed on the lower surface of the bulging portion; the overhang 36 and the flange 38 are engaged by a fixing ring 39. The flange portion 38 faces the overhang portion 36, and has a predetermined thickness, for example, bulging annularly outward over the entire circumference at the lower end of the nipple 3. A characteristic structure is provided in the region of the base 35.
In fig. 8, 9, and 10, the bulging portion 41 is provided: the diameter of the nipple ring 34 is substantially increased continuously with the expansion of the breast.
between the bulging portion 41 and the flange portion 38, a groove of a reduced diameter portion 42 consisting of a groove or a slit having a size into which the inward flange portion 24 illustrated in fig. 2 enters is formed. It is particularly important that at least a part of the reduced diameter portion 42 is provided so as to enter deeply, and as will be understood from fig. 10, is formed to a position deeper than the depth of the flange portion 24 of the lid 2. Specifically, the reduced diameter portion 42 is formed to be deeper than the inner end of the flange portion 24 of the cap 2 by a dimension D1 when the flange portion 24 of the cap 2 is fitted into the reduced diameter portion 42.
On the other hand, the flange 38 is provided with the air return valve 51, and the air return valve 51 is formed so as to protrude from the lower surface of the integrated portion 50 and so as not to be limited to the inside of the thickness of the flange 38. Specifically, a square formation portion 51 as shown in fig. 13 is provided in a predetermined region of the flange portion 38. As shown in fig. 9 and 10, the integral portion 50 is depressed by a region with respect to the upper surface of the flange portion 38, and the integral portion 50 form valve bodies 51a and 51b as movable pieces having a thin wall obliquely downward. The valve bodies 51a and 51b are provided so that the respective leading ends (lower ends in fig. 11) are closed to prevent liquid from leaking; on the other hand, with respect to the air in the direction of the arrow a1, the front end is opened by the air pressure and forms the slit 52, so that the air flows into the bottle 1. In the present application, as shown in fig. 9, 12, and 13, the integral portion 50, and the valve bodies 51a and 51b, which are the movable pieces at the base of the integral portion 50, are integrally formed.
That is, the air return valve 51 has two valve bodies 51a and 51b whose distal ends are butted against each other so as to form a slit 52 that opens and closes so that the cross sections thereof are inverted triangular, and the base end portions (the integrated portions 50) of these valve bodies are directly formed integrally with the flange portion 38 of the base portion 35.
As an example of the present application, as shown in fig. 13, the slit 52, which is an opening of the air return valve 51, is a linear opening and is formed in a direction parallel to the circumferential direction of the flange portion 38.
The air return valve 51 of the present invention introduces air from the outside when the internal pressure of the bottle 1 is reduced due to suction of milk or the like in the bottle 1 in a state where the nipple 3 is attached to the bottle 1 via the cap 2 (i.e., the state of fig. 1), and closes when the liquid in the bottle attempts to flow out to the outside.
As shown in fig. 5 and 6 and 7, the lower surface 44 and the upper surface 45 of the flange portion 38 are textured (shown in mesh) to reduce friction of the flange 45 with the cap 2 and to reduce friction of the flange 44 with the bottle 1. As shown in fig. 10 and 11, the valve body is suspended at the periphery, such as 51a and 51 b. To reduce the transmission of compression set. As shown in FIG. 9, the thickness of the integral part 50 is designed to be thin, preferably 0.5 to 1.5 mm; to reduce the transmission of compression set. In the present embodiment, the wall thickness F1 of the valve body 50 is 0.8 mm. The above-described structural design makes it possible to prevent the tip ends (the position of the slit 52) of the valve bodies 51a and 51b from sliding laterally and causing a misalignment, which is a problem in which the valve bodies cannot overlap each other, even if a screwing force acts in the circumferential direction when the nipple 3 attached to the cap 2 is attached to the bottle 1 and the cap 3 is screwed in.
As will be understood with reference to fig. 9 and 10, the integrated portion 50 of the air return valve 51 forms a gap G1 through the subsidence space 43. The bulge 41 is provided with a groove 42 at a position just above the air return valve 51, and a gap D1 is formed with the upper opening 21 of the screw cap 2. G1 is connected to D1.
In the present embodiment, configured as described above, even if the internal pressure of the bottle 1 is reduced during nursing, the outside air passes through the concave groove 42 of the bulging portion 41 and through the gaps D1 and G1 to reach the air return valve 51 as shown by the arrow a1 in fig. 10. In fig. 10, the check valve 51 opens the lower ends of the valve bodies 51a and 51b, and injects the outside air from the slit 52 into the bottle 1 as indicated by an arrow a2 in fig. 10, so that the nipple 3 is not collapsed by a decrease in the internal pressure of the bottle 1, and nursing can be continued without hindrance.
