Definitions
- the present invention relates to a nipple for a nursing bottle through which an infant can take milk with a chewing action, or a chewing muscle action.
- the initial development of the masticatory organ could be said to have three stages.
- the first stage corresponds to a period during which the infants obtain the basic muscle force of masticatory organ by taking the mother's milk, and at the same time, the pattern of chewing action is acquired.
- a conventional nipple has a hollow body portion 83 formed between a hemispherical papilla portion 80 provided with a milk sucking hole 81 and a flange-shaped connecting portion 82 connected to a neck portion of the nursing bottle.
- the infant can take the milk in the nursing bottle through the sucking hole 81 by sucking the papilla portion 80 in its mouth. In other words, the infant can take the milk by entirely performing the sucking operation.
- the inventor of the present invention has proposed a nipple for a nursing bottle provided with a check valve disposed between a papilla portion and a hollow body portion so adapted to be closed upon the compression of the papilla portion for preventing the flow of drink and to be opened in the normal uncompressed state of the papilla portion (See EP-A-0 384 394).
- the check valve permits the flow of the drink when the compressing force to the papilla portion is being released, a drink such as milk in the nursing bottle can be introduced through the check valve to the papilla portion.
- the check valve prevents the flow of the drink thereby enables the drink introduced to the papilla portion to dispense through a dispensing hole in the papilla portion into the cavitas oris of the infant.
- the infant can take the drink in the nursing bottle successively by repeatedly chewing the nipple.
- the inventor has fulfilled a nipple which can ensure the sufficient development of the masticatory organ of an infant who grows up with being fed an artificial milk.
- the inside of the nursing bottle or the nipple tends to be negative pressure. Therefore, when the negative pressure progresses in the nipple with check valve for a nursing bottle, the compressed papilla portion remains in the deformed state thereby the check valve also remains in the closed state.
- Such the closed state of the check valve particularly tends to happen in a nipple which has a dispensing hole in the papilla portion formed so adapted to be closed except when the drink is dispensed for preventing the flow back of the air therethrough into the papilla portion when the compressed papilla portion restores the original shape thereof.
- the above mentioned closed state of the check valve causes to prevent the drink from flowing from the body portion of the nipple to the papilla portion, thereby the papilla portion can not restore its shape and unable to dispense the drink from the nipple.
- the another object of the present invention is to provide a nipple for a nursing bottle which prevents the poor dispensation of the drink.
- this invention provide a nipple for a nursing bottle comprising: a connecting portion adapted to be connected to a neck portion of a nursing bottle; a hollow body portion integral with the connecting portion; a papilla portion integral with the body portion; a dispensing hole for dispensing a drink from the papilla portion; a diaphragm disposed between the body portion and the papilla portion for partitioning the inside of the nipple; a slit formed in the diaphragm and adapted to be opened in the normal uncompressed state of the nipple for permitting the flow of the drink from the body portion to the papilla portion and to be closed upon the compression of the nipple by an infant for preventing the flow of the drink from the body portion to the papilla portion; characterised in that a communicating portion is formed in the diaphragm for slightly permitting the flow of the drink from the body portion to the papilla portion in a case where the
- a drink such as milk in the nursing bottle can be introduced to the papilla portion through the slit opened while the nipple is not compressed by the infant.
- the slit is closed and prevents the flow of the drink from the body portion to the papilla portion, thereby the drink introduced in the papilla portion can be dispensed through a dispensing hole formed in the papilla portion into the cavitas oris of the infant.
- the infant can take the drink in the nursing bottle successively by repeatedly chewing the nipple.
- the communicating portion allows the slight quantity of the drink to be introduced from the body portion to the papilla portion, so that the restoration of the deformed papilla portion is started to open the closed slit immediately.
- the connecting portion is provided with an air valve for introducing the air into the nursing bottle.
- the air is introduced into the nursing bottle, the application of the excessive negative pressure onto the nursing bottle can be avoided during the infant is taking the drink in the nursing bottle. Consequently, the possibility that the slit remains in the closed state can be reduced.
- Figure 1 is a sectional view illustrating a nipple A for a nursing bottle according to the present invention
- Figure 5 is a perspective view of the nipple A.
- the above nipple A is formed by integrally connecting a papilla portion 1, tip of which is in a round shape, through a substantially tapered tube-shaped body portion 2 to a flange-shaped connecting portion 3 adapted to be connected to a neck portion B1 of a nursing bottle B.
- the above described nipple A is manufactured by molding a rubber material such as isoprene rubber, silicone rubber or polyurethane rubber in a predetermined shape by injection molding, blow molding, dip molding or the like.
- the nipple A is connected to the nursing bottle B by pinching the connected portion 3 between the cap C and a neck portion B1 of the bottle B.
- the papilla portion 1 is provided with a tip in which is formed a dispensing hole 11 for dispensing the drink such as artificial milk from the inside of the nipple A into the cavitas oris of an infant.
- the dispensing hole 11 is of such a construction as to be closed except when the drink is dispensed, which can be obtained by adapting such a shape as a cross cut (see Figures 6 and 7), a so-called super cross cut provided with a dent 11a in the inner side of the cross cut (see Figures 8 and 9), and a Y-shaped cut.
- the papilla portion 1 has flat sidewalls 21 opposed to each other, which form the opposite sides of the papilla portion 1.
- the above mentioned nipple A has a check valve 5 disposed therein for partitioning the inside of the nipple A between a papilla portion side A1 and connecting portion side A2.
- the check valve 5 takes in the form of a diaphragm 51 disposed between the papilla portion 1 and the body portion 2 and a slit 52 formed in the center of the diaphragm 51.
- the slit 52 extending in the parallel direction with the sidewalls 21.
- the slit 52 has two concave surfaces 52a of which both ends are opposing and gradually approaching to each other.
- a maximum opening width L of the slit 52 is established to approximately 0.5 to 5 mm.
- the above slit 52 of the check valve 5 is closed when the peripheries of the check valve 5 is compressed in the direction of arrow X in Figure 2 (See Figure 3).
- the application of the compression force substantially prevents the flow of the drink from the body portion 2 to the papilla portion 1.
- slit is opened thereby the drink flows from the body portion 2 to the papilla portion 1.
- the above diaphragm 51 has a pinhole 53 as a communicating portion for communicating between the papilla portion 1 and the body portion 2.
- the pinhole 53 is formed in one or plural positions of the diaphragm 51, so as to allow slight quantity of the drink to flow from the body portion 2 to the papilla portion 1 in a case where the slit 52 is closed.
- the diaphragm 51 has certain thickness to prevent the collapse when the slit 52 is closed.
- the connecting portion 3 has circular ribs 34 adapted to be fitted to the neck portion B1 of the nursing bottle B at predetermined intervals with one or plural air valve 33 (See Figures 1 and 4) formed at predetermined positions between the ribs 34.
- the air valve 33 takes in the form of a short line-shaped slit 33a formed in a bottom of a cup-shaped hollow projection 35 formed between the ribs 34.
- the slit 33a is extending in the radial direction. This is to prevent the slit 33a, when the connecting portion 3 is tightened with the cap C, from being distorted in the tightening direction of the cap C and thereby being closed.
- the air valve 33 which is formed between the ribs 34, is protected from external force by these ribs 34.
- the hollow projection 35 has preferably a protruding height of approximately 2 mm and a thickness of 6 mm or more. It is preferable to form an air pass between the connecting portion 3 and the cap C for introducing the air into the air valve 33.
- the infant when an infant puts the papilla portion 1 of the nipple A in its mouth, the infant instinctively tends to chew the papilla portion 1.
- the papilla portion 1 is compressed and at the same time, the check valve 5 is closed by a chewing action, thereby the drink introduced into the papilla portion 1 is dispensed into the cavitas oris of the infant through the dispensing hole 11.
- the compression force for the nipple A is released, the papilla portion 1 is restored to its original shape by an elastic restoring force and correspondingly, the slit 52 which forms the check valve 5 is opened. Consequently, the drink is introduced again from the body portion 2 into the papilla portion 1.
- the infant can take the drink in the nursing bottle B by repeatedly chewing the papilla portion 1.
- the above nipple A allows an infant to take a drink by the chewing action as described above, even an infant having cleft palate can easily take the drink therewith.
- the drink can be introduced from the body portion 2 side through the pinhole 53 to the papilla portion 1 side even if where the slit 52 of the check valve 5 remains in the closed state (see Figure 10) because the compressed papilla portion 1 cannot be restored owing to the excessive negative pressure of the inside of the papilla portion 1. This allows the deformed papilla portion 1 to start being restored to its original state, causing the slit 52 to be opened earlier.
- the air valve 33 formed in the connecting portion 3 introduces the air to the inside of the nursing bottle B, the excessive negative pressure can be avoided as far as possible. Consequently, the possibility that the slit 52 of the check valve 5 remains in the closed state can be reduced as little as possible even if the infant takes the drink successively.
- the papilla portion 1 has the flat sidewalls 21 opposed to each other and the slit 52 formed in parallel with the above flat sidewalls 21, the direction of the nipple A can be easily identified when an infant puts the nipple A in its mouth. More specifically, the slit 52 can be positioned in a suitable direction by only making the infant puts the nipple A in its mouth such that the above flat sidewalls 21 are parallel to the gums of the infant. Furthermore, because the above sidewalls 21 fit the mouth of the infant, the infant can easily chew the nipple A.
- the dispensing hole 11 Because the dispensing hole 11 is closed except when the drink is dispensed, it prevents the air from being introduced to the papilla portion 1 through the dispensing hole 11 when the drink is introduced through the slit 52 to the papilla portion 1. This facilitates the introduction of the drink to the papilla portion 1.
- the body portion 2 should have certain thickness for preventing the easily distortion because the purpose of the sufficient gnathic action can not be ensured if the body portion 2 is easily distorted when the infant puts the body portion 2 in its mouth.
- a plurality of dispensing holes 11 may be provided in the papilla portion 1.
- the dispensing holes 11 shown in Figure 11 are short cut lines each having a length of approximately 0.5 to 1.5 mm, totaling approximately 2 to 10 in number. These dispensing holes 11 are formed in a direction parallel to the sidewall 21.
- the dispensing holes 11 thus constructed will not permit the drink to be dispensed therethrough only by sucking the nipple A. By chewing the nipple A, however, the drink will easily be dispensed. As a result, the infant is easily forced to take a drink not by the sucking action but by the chewing action.
- the maximum opening width L of the slit 52 is preferably not more than one half of the shorter length L1 of the inside of the papilla portion 1 (see Figure 12).
- the longitudinal length M of the slit 52 is preferably not less than one half of the longer length M1 of the inside of the papilla portion 1.
- the wall thickness of the nipple A may be uniform throughout. However, it is desirable that right and left portions in Figure 2 are thinner than upper and lower portions because the slit 52 in the check valve 5 is easily closed.
- the flat sidewall 21 may be formed at one side of the papilla portion 1.
- Figure 15 shows another embodiment in which a body portion 2 is communicate with a papilla portion 1 through a small clearances 54, instead of the pinholes 53, formed at the end portions of a slit 52 being closed.
- the end portions of the slit 52 are provided with longitudinally extending short line portions 52b which form the clearances 54 at the opposite ends of the slit 52 being closed. Therefore, the slit 52 can be opened earlier by introducing the drink through the clearances 54, even if the papilla portion 1 is not restored in its original shape.
- the papilla portion 1 may shape in a spherical cross section having a round tip as shown in Figures 16 and 17, or in an elliptical cross section as shown in Figure 18. Further, as shown in Figure 19, the whole shape of the nipple A may be caused to have predetermined directionality such that the nipple A can fit the cavitas oris of the infant.
- the air valve 33 may be in the form of a penetrating hole which penetrating the connecting portion 3.
- the diaphragm 51 of the check valve 5 may be smoothly integrally formed on the inner wall of the body portion 2.
- the strength of the diaphragm 51 can be increased, so that the collapse of the diaphragm 51 can be effectively prevented under the situation where the slit 52 is closed.
- the check valves 5 may be formed two in number apart from each other by a predetermined interval (see Figure 22), which can enhance the hermetical characteristic of the papilla portion 1.
- the slits 52 formed in the diaphragms 51 are directed so as to be perpendicular to each other (see Figures 23 and 24), the nipple A can be chewed in two directions selectively.
