Description
Technical Field
The present invention relates to a membrane and device for promoting bottom ventilation of an anti-expansion baby bottle. The invention also relates to an anti-expansion bottle with the bottom being ventilated.
Background
In the prior art, air is promoted to enter the baby bottle in the sucking process, so that the health problem of children is avoided. The interior of the bottle is vented from the bottom of the bottle itself or from the teat through a conventional anti-expansion valve. For bottom venting of the bottle, prior art devices include a membrane located on a structural portion of the bottle bottom that is configured to allow air to enter the interior volume of the bottle. In particular, the diaphragm has a standard slit formed therein which opens as a result of the negative pressure generated in the bottle when the milk is sucked, so that a certain amount of air is sucked in from the outside, which will equalize the pressure. It should be noted that when a given negative pressure value is reached in the bottle, the slit in the membrane opens to provide venting. The value ranges from a minimum value to a maximum value, taking into account various factors such as: the volume of the baby bottle, the type of liquid to be sucked from the bottle, the need to avoid dripping of liquid from the bottle.
Disclosure of Invention
Problems of the prior art
The prior art bottom vent for bottles presents various problems. First, since the slit undesirably opens in response to a pressure higher than an external pressure, the liquid held in the bottle may leak. Secondly, the opening of the incision due to the entry of air into the bottle requires excessive suction, which, in addition to fatigue, can cause health problems such as inflammation. In addition, the prior art diaphragm requires a high degree of negative pressure to open the passageway and allow air to enter the baby bottle. This requires the infant to increase the suction force on the nipple.
Objects of the invention
It is an object of the present invention to provide a membrane, a bottom vent for a baby bottle and a baby bottle which avoid the above-mentioned drawbacks of the prior art.
In particular, it is an object of the present invention to provide a membrane which is able to ensure the entry of air into the bottle and the balancing of the pressure, while reducing the liquid sucking force required by the baby.
Another object of the present invention is to provide a device for equalizing the pressure inside a bottle which is capable of ensuring the entry of air and preventing the leakage of the liquid contained inside the bottle.
It is another object of the present invention to provide a baby bottle which can equalize the pressure inside the bottle when the liquid contained in the bottle is sucked out of the bottle.
The above technical aim and objects are substantially achieved by a membrane, a bottom vent for baby bottles and a baby bottle comprising the technical features disclosed in one or more of the claims.

Detailed Description
Individual features described with reference to specific embodiments are to be considered as additional features and/or features interchangeable with other features described with reference to other exemplary embodiments, even if not explicitly stated.
Referring to the drawings, numeral 1 indicates a baby bottle from which a baby sucks liquid. The baby bottle 1 includes: a bottle 2 configured to contain a liquid such as milk or water; a nipple 3 through which the baby sucks the liquid; and means 10 for balancing the pressure inside the bottle 2. In particular, the bottle 2 extends along a first axis X-X between an upper opening 2a and a lower opening 2b, the teat 3 being coupled to the upper opening 2a and the pressure-equalizing device 10 being coupled to the lower opening 2 b. The teat 3 and the pressure equalising means 10 are preferably both removably coupled to the bottle 2.
The pressure equalisation means 10 can equalise the pressure within the bottle whilst ensuring a fluid tight seal both when sucking (i.e. when using the bottle) and when at rest when not using the baby bottle.
As used herein, when the baby does not draw liquid through the nipple 3 (i.e. when the first axis X-X of the bottle 2 is substantially perpendicular to the conventional support surface) it means that the baby bottle 1 is not in use. In other words, the baby bottle 1 is not used when the bottle 2 is in the upright position and the pressure in the bottle is equal to or higher than the ambient pressure.
As used herein, when the lower opening 2b associated with the pressure equalizing device 10 is facing upwards and the bottle is inclined to the normal supporting surface, it means that the baby bottle 1 is used. In other words, when a baby sucks liquid through the teat 3, the baby bottle 1 is in use, creating a negative pressure within the bottle 2 relative to the external environment.
The pressure equalizing device 10 is configured to ensure a fluid seal and prevent leakage of liquid from the bottle 2, and to ensure that air enters from the environment outside the bottle 2 when liquid is sucked out of the bottle. In particular, the pressure balancing device 10 comprises a bottom cap 11 removably coupled to the bottle 2 of the baby bottle and a vent membrane 100.
According to an embodiment of the invention, the vent membrane 100 is configured to engage with the bottom of the bottle 2, preferably defined by a bottom cap 11, the bottom cap 11 having one or more holes 12 formed therein for venting air from the external environment into the bottle 2.
The diaphragm 100 comprises a central flexible portion 101, a first ring portion 102 and a second ring portion 103 connected to each other.
The central flexible portion 101 is elastically deformable to reversibly move between a rest configuration (rest configuration) when the pressure inside the bottle 2 is equal to or higher than the pressure of the external environment and a venting configuration when the pressure inside the bottle 2 is lower than the pressure of the external environment. In other words, the central flexible portion 101 is in a rest configuration when the baby bottle 1 with which it is associated is not in use. Conversely, the central flexible portion 101 is in a venting configuration when the baby bottle 1 with which it is associated is in use.
The first ring portion 102 concentrically surrounds the central flexible portion 101 and is connected to the central flexible portion 101.
Preferably, the first ring portion 102 comprises a bottom surface 102a facing the bottom of the bottle 2 and a top surface 102b opposite to the bottom surface 102a and facing the inside of the bottle 2.
The second ring portion 103 concentrically surrounds the first ring portion 102 and is connected to the first ring portion 102. The central flexible portion 101 bulges towards the inside of the bottle 2 with respect to the second ring portion 103, and the first ring portion 102 connects the central flexible portion 101 and the second ring portion 103, respectively. In other words, the central flexible portion 101 is spaced along the first axis X-X with respect to the second loop portion 103 by the first loop portion 102.
The second ring 103 has an inner periphery to which the first ring 102 is connected and an outer periphery that can be coupled to the bottle 2.
Preferably, the second ring 103 has an annular groove 107 formed on the outer periphery to facilitate coupling and fluid-tightness between the membrane 100 and the lower opening 2b of the bottle 2 when the baby bottle is assembled.
More preferably, the second ring 103 has at least one tab 106 projecting from the second ring 103 and configured to facilitate the action of pulling out the diaphragm 100 and positioning the diaphragm 100 on the bottom cover.
As shown, the central flexible portion 101 includes:
-a central domed region 101 a;
an annular recess 101b, which externally concentrically surrounds the central dome-shaped zone 101a and is connected to the central dome-shaped zone 101 a;
an annular rib 101c concentrically surrounding said annular recess 101b, the annular rib 101c being connected with the annular recess 101b on the inside and with the first ring portion 102 on the outside;
to allow air to enter the bottle 2 from its bottom through the holes, the annular rib 101c comprises a plurality of channels 104, the channels 104 being configured to move between:
an open position allowing air to pass from the external environment into the interior of the bottle 2 when the central flexible portion 101 is in the venting configuration; and
a fluid-tight closed position when the central flexible portion 101 is in the rest configuration.
The passage moves the central domed region 101a of the annular recess 101b away from the first ring 102 towards the interior of the bottle from the rest configuration to the vent configuration. As a result, as the central domed region 101a and the annular recess 101b move apart, the annular rib 101c elastically deforms and the channels 104 correspondingly open to allow air to enter the bottle. In particular, the central flexible portion 101 in the rest configuration is substantially disc-shaped with a corrugated portion comprising a central dome-shaped portion 101a, an annular recess 101b and an annular rib 101 c. Conversely, in the venting configuration, the central flexible portion 101 is generally conical or frustoconical.
According to a preferred embodiment, the central flexible portion 101 has a top surface facing the inside of the bottle 2 and a bottom surface facing the bottom of the bottle 2, so that:
the outer surface of the central domed region 101a has a first radius of curvature R1 ranging from 5.5mm to 6.5 mm;
the outer surface of the annular recess 101b has a second radius of curvature R2 ranging from 1.5mm to 2 mm;
the outer surface of the annular rib 101c has a third radius of curvature R3 ranging from 1mm to 1.5 mm.
Preferably, the central flexible portion 101 sheet has a thickness S from 1mm to 1.5 mm.
Preferably, the annular rib 101c has a thickness S2 of from 0,4mm to 0.6 mm.
According to a preferred embodiment, the channels 104 are spaced apart from each other along the annular rib 101c to form a uniform air passage from the external environment to the internal environment. Preferably, the channels 104 are equally spaced from each other along the annular rib 101 c. Advantageously, the provision of a plurality of channels 104 along the annular rib 101c facilitates the passage of air in the venting configuration whilst reducing the force necessary for the infant to drink from the teat.
According to a preferred embodiment, each channel 104 is formed without removing material from the central flexible portion 101. Preferably, each channel 104 is obtained by tearing or cutting the central flexible portion 101, thus avoiding any material removal. Advantageously, the passages 104 thus obtained avoid undesired fluid leakages when in the closed position.
According to a preferred embodiment, each channel 104 extends between a first end 104a and a second end 104b in a direction of extension Y-Y oriented radially with respect to the centre of the annular rib 101 c. In other words, for each channel 104, the first end 104a faces the central dome-shaped portion 101a, while the second end 104b faces the first annular portion 102 along a direction of extension Y-Y passing substantially through the centre of the annular rib 101 c. Advantageously, the radial extension of the channel 104 contributes to:
a passage between a closed position and an open position when the flexible central portion 101 moves from the rest configuration to the venting configuration;
a passage between an open position and a closed position when the flexible central portion 101 is moved from the venting configuration to the rest configuration.
According to a preferred embodiment, each channel 104 has a rectilinear and/or curvilinear profile. Preferably, each channel 104 has a crescent-shaped profile.
With respect to the materials, in order to ensure the correct operation of the device 10, the membrane 20 is preferably made of a material preferably composed of a shore hardness of 40 and a nominal modulus of elasticity of 770 x 105Pa of silicone material. Advantageously, the diaphragm 100 may achieve optimal operating conditions for opening the passageway 104 for effectively rebalancing the pressure differential that occurs within the baby bottle when liquid is sucked from the baby bottle.
It should also be noted that as the negative pressure within the bottle 2 of the baby bottle 1 increases, the deformation of the diaphragm 100 also increases, and therefore the channel 104 opens wider, effectively rebalancing the pressure differential.
According to a preferred embodiment, the membrane 100 comprises a stiffening member 105, the stiffening member 105 being adapted to at least partially stiffen the first loop 102. In particular, the stiffening member 105 is configured to facilitate reversible passage between the resting configuration and the venting configuration by concentrating compressive stresses on the flexible central portion 101.
Advantageously, the reinforcing member 105 concentrates the compressive stress on the central flexible portion 101.
Advantageously, the stiffening member 105 contributes to a proper adhesion of the membrane 100 to the bottom of the bottle 1, thus contributing to the movement of the central flexible portion 101 only.
Preferably, the combination of the annular reinforcing member 105 between the top surface 102a and the bottom surface 102b of the first ring portion 102 is in the first ring portion 102. Advantageously, inserting the stiffening member 105 into the membrane 100 facilitates the manufacturing process.
According to the embodiment, as an alternative to the above, the annular reinforcing member 102 is coupled to the top surface 102b in a state of surrounding the first ring portion 102.
According to another embodiment, as an alternative to the first two embodiments, the annular reinforcing member 105 is coupled to the bottom surface 102a such that the first loop 102 surrounds the annular reinforcing member 105.
According to a preferred embodiment, the annular stiffening member 105 is configured to stiffen the first loop portion 102 by extending along the first loop portion 102 between the second loop portion 103 and the central flexible portion 101. Advantageously, when the entire first loop 102 is reinforced, the concentration of compressive stresses on the central flexible portion 101 is improved.
According to a preferred embodiment, the stiffening member 105 is made of a rigid polymer material, ensuring correct movement of the central flexible portion 101 and preventing undesired deformations caused by the first loop portion 102.
In a preferred embodiment of the pressure equalizing device 10 of the present invention, the diaphragm 100 is coupled to the bottom cover 11, and the bottom cover 11 includes:
a central bottom 11a having at least one hole 12, hole 12 being intended to provide fluid communication between the external environment and the inside of bottle 2;
a first bottom ring 11b concentrically surrounding the central bottom 11a and connected to the central bottom 11 a;
a second bottom ring 11c concentrically surrounding the first bottom ring 11b and connected to the first bottom ring 11 b. The central bottom 11a is raised towards the inside of the bottle 2 with respect to the second bottom ring 11 c. In addition, the first bottom ring 11b connects the central bottom portion 11a and the second bottom ring 11 c.
That is, the vent membrane 100 is covered on the bottom cover 11 so that:
when the pressure in the bottle 2 is higher than or equal to the external pressure, the central flexible portion 101 is in the rest configuration at least partially resting on the central bottom 11 a;
when the pressure in the bottle 2 is lower than the external pressure, the central flexible portion 101 is in a venting configuration in which the central bottom 11a is axially spaced apart, allowing the passage of air from the external environment to the inside of the bottle 2.
Preferably, the first bottom ring 11b has an outer surface facing the bottom surface 102a of the diaphragm and adapted to promote adhesion between the diaphragm 100 and the bottom cover 11. For example, the outer surface of the first bottom ring 11b is corrugated or has friction elements.
More preferably, the central bottom 11a has a pointed shape with a hole 12 formed around the top thereof. Thus, in the rest configuration, the central domed region 101a at least partially abuts the cusps of the central base 11 a.
Even more preferably, the central domed region 101a covers the aperture 12 formed in the base cap, thereby ensuring a fluid-tight seal when the bottle is not in use.
According to a preferred embodiment of the pressure equalizing device 10, the assembly of the first annular portion 102 with the central portion 101 and the assembly of the first bottom ring 11b with the central bottom portion 11a have a first and a second complementary dome shape, respectively. That is, the assembly of the first bottom ring 11bB with the central bottom portion 11a is coupled with the assembly of the first ring portion 102 with the flexible central portion 101.
Preferably, when the diaphragm 100 is coupled to the bottom cover 11, the annular rib 101a bulges from the central bottom 11a and the first bottom ring 11b, so as to facilitate the passage between the rest configuration and the venting configuration and avoid undesired liquid leakages.
According to a preferred embodiment, the second ring portion 103 and the second bottom ring 11c each define a ring. In particular, the second bottom ring 11c of the cover 11 is configured to cooperate with the second ring portion 103. Advantageously, the stiffening member 105 maintains the dome shape of the membrane 100, providing easy coupling with the dome of the bottom cap 11c and preventing undesired movement of the second ring 103 from the second bottom ring 11c, whether or not the baby bottle is in use.
