Field

[0001] The present invention relates to an assembly for dispensing a substance into a receptacle. In particular, the present invention relates to an assembly for dispensing infant formula into a feeding bottle.

Background

[0002] Baby bottles are widely used by parents and caretakers to feed their children. Most commonly, baby bottles are used to feed infant formula to babies or young children. The process to prepare a bottle of infant formula would involve measuring an amount of infant formula, placing it into the bottle, adding water and mixing the contents together. Even though this process appears to be relatively straightforward, preparing a bottle of infant formula can be quite stressful especially when the baby is crying. This process becomes more difficult when the parents are travelling with the baby and the bottle of infant formula is prepared outside the comfort of a home.

[0003] Traditionally, when the parents are travelling with the baby, the parents would pre measure an amount of infant formula in a container and take it outdoors with them so that they can pour the infant formula into the baby bottle and mix with water when feeding it to the baby. However, this process is time consuming and laborious.

[0004] Numerous devices have been disclosed for storing a powder within a bottle until ready for consumption. For example, the bottle may comprise an inner tube that contains a substance (liquid or powder) to be kept separate from the substance in the bottle prior to use. In use, the user will unscrew the cap of the bottle and pull the inner tube upwards which detaches the inner tube from the base of the bottle and permitting the substances to mix. Whilst this bottle provides a method to mix two substances together, the bottle is not configured for use with infant formula powders nor suitable for use with babies or young children.

Description of Embodiments

[00059] According to a first embodiment of the present invention, there is provided an assembly for dispensing a substance into a receptacle 100 as shown in figures 1 to 4A.

[00060] With reference to figures 2 to 4, the assembly 100 is comprised of a number of components including a first portion 101 , a chamber 102, a seal 103 and a removable stop member 104. As illustrated in the drawings, the first portion 101 is connected to the opening of the receptacle 106 by way of a threaded connection. The first portion has internal threads which are configured to connect with the external threads 108 of the receptacle 106. An inwardly extending flange 105 is formed at the top of the first portion 101 to support the removable stop member 104 (as shown in figure 3). The first portion further comprises an inner wall with a plurality of angular protrusions 107 which enables the chamber to lock in place when the chamber is moved in a downwardly direction upon force or pressure by the user. This can be seen in a close up view in figure 4A.

[00061 ] The chamber 102 contains a substance 109. In a preferred embodiment, the substance is preferably an infant formula powder, although it is envisaged that other forms of beverage powders can be stored in the chamber. As shown in figures 3 and 4, the chamber 102 is partly located within the first portion 101. The chamber 102 has an inwardly extending upper flange 1 14A and the upper part of chamber 102 is connected to a threaded collar 1 10. A mouth portion 1 1 1 in the form of a teat has a lower flange that is sandwiched between flange 1 14A and the inwardly extending flange 1 10A of collar 1 10. The chamber 102 also has a lower flange 1 14B which is configured to abut with the plurality of angular protrusions 107 of the first portion 101 . On one end of the chamber relative to the seal 103, the chamber is slanted in a downwardly direction so that upon force or pressure by the user, the slanted end of the chamber 1 12 will come into contact with a portion of the seal 103. A spoke (not shown in the drawings) may be located inside the chamber to provide structural support for the substance 109.

[00062] As shown in figures 2 and 3, the seal 103 is located below the first portion 101 and acts as a barrier between the chamber 102 and the lower portion of the receptacle 106. The seal may be glued or heat sealed to the bottom edge of the chamber, as will be known to persons skilled in the art. The seal 103 includes a tab 1 13 which is positioned between a wall of the receptacle 106 and the first portion 101 . This acts to retain the tab 1 13 in that position even when the seal has been opened. The seal can be made of any material that provides a moisture barrier. However, it is preferred that the seal is made of a plastic material.

[00063] Returning to the chamber 102 in figure 3, the chamber 102 comprises external threads 120 to connect with internal threads 121 of the threaded collar 1 10. The threaded collar 1 10 is adapted to engage with a mouth portion 1 1 1 such as a teat or nipple. Prior to use and before the substance 109 is released into the receptacle 106, the threaded collar 1 10 is positioned above the removable stop member 104. As the removable stop member 104 is effectively located in the gap between the lower end of threaded collar 1 10 and first portion 101 , downward movement of the threaded collar 1 10 relative to the first portion 101 is not possible. As a result, the chamber is effectively held or locked in the position shown in figure 3 whilst the removable stop member 104 is in place, thereby preventing delivery of the substance 109 form the chamber into the receptacle 106.

[00064] In order to deliver the substance 109 into the receptacle 106, the removable stop member 104 is removed and this creates a space between the threaded collar 1 10 and first portion 101. The space enables the user to push the threaded collar 1 10 in a downwardly direction onto the first portion 101. The user may also rotate the threaded collar during downward pushing to facilitate the downward movement. In a preferred embodiment, the removable stop member functions as a tamper ring.

[00065] The assembly 100 also has a circular ring 1 16 disposed between the flange of the first portion 101 and the lower flange of the chamber 1 14B. This circular ring 1 16 may act as an internal seal to prevent spillage or leakage of the liquid in the receptacle 106. A further external ring 1 17 is located below the first portion 101 . The external ring 1 17 is configured to act as an outer seal of the assembly 100 against the receptacle 106.

[00066] In operation, the user will remove the removable stop member 104 from the assembly 100. The user will push the threaded collar 1 10 downwardly towards and onto the flange of the first portion 101 , thereby moving the chamber 102 in a downwardly direction. As the chamber is moved in a downwardly direction, this causes the slanted end of the chamber 1 12 to come into contact with a portion of the seal 103 which will cause the seal to open and release the substance 109 into the receptacle 106 (as shown in figure 4). The tab 1 13 of the seal retains the seal and stops the seal becoming free to drop into the liquid in the receptacle. The user will then mix the substance (e.g. infant formula powder) with the substance inside the receptacle (e.g. water) until the substances are combined. Once the substances are combined, the user will remove the protective lid 1 15 to feed the infant formula to the baby. If desired, the user can microwave or warm the substance in the receptacle to an appropriate temperature before feeding the baby.

[00067] A second embodiment of the present invention will be described with reference to Figures 5 to 1 1. The fundamental configuration of the apparatus of the further embodiment is similar to the embodiment described above.

[00068] As illustrated in Figures 5 and 6, the assembly 200 is comprised of a number of components including a first portion 201 , a chamber 202, a seal 203, a second portion 205 located above the first portion 201 , a chamber cutter 206, a removable member 204, a third portion 207 that is detachably coupled to the removable member 204, a mouth portion 21 1 such as a teat or a nipple. In this embodiment, the first portion 201 has internal threads which are configured to connect with the external threads 208 of the receptacle 209. A flange 210 is formed at the top of the first portion 201 to support the second portion 205 (as shown in Figure 7). As shown in Figures 6 to 8, the second portion 205 is attached to a portion of the chamber 202 and the first portion 201 . Prior to the release of the baby formula, the second portion 205 is also attached to a removable member 204. As illustrated in Figure 7, the removable member is coupled to a third portion 207. The third portion comprises a mouth portion 21 1 such as a teat.

[00069] A chamber cutter 206 is also located partially within the first portion 201 and chamber 202. On one end of the chamber cutter 206, a slant in a downward direction is provided which is configured to come into contact with a portion of the seal 203. It is envisioned that the chamber cutter 206 may be adapted to include different shapes and/or configurations. The chamber cutter is provided to cut or open the seal, to thereby open the chamber and allow the contents of the chamber to be delivered to the receptacle. The chamber cutter 206 may also include a spoke for structural integrity and support. In a preferred embodiment, the seal 203 will have a tab 213 that is located between a wall of the receptacle 209 and the first portion 201. The tab 213 is permanently fixed between the wall of the receptacle and the first portion thereby allowing only a portion of the seal 203 to fall into the receptacle as the chamber cutter pierces the seal 203. The seal 203 may be made of a plastic or foil material.

[00070] Figure 10 shows a bottom perspective view of the seal 203. In a preferred embodiment, the seal 203 will further include a disc or displacer 214. The disc 214 may be connected to a portion of the first portion 201 and/or chamber 202. The disc 214 may also be attached to the seal 203 and is configured to partially fall into the receptacle 209 together with the seal 203 when the seal is broken to release the substance. The disc 214 acts as a stiffener and prevents the seal 203 from curling when it is inside the receptacle. The disc 214 may be made of a plastic material.

[00071 ] Similar to the previous embodiment described above, the chamber 202 has a circular ring 215 disposed on a flange of the chamber to prevent spillage or leakage of the liquid in the receptacle 209.

[00072] In operation of the second embodiment, the removable member 204 will be removed from the assembly 200. A user will then push the third portion onto the second portion 205 in a downwards direction. In this configuration, the action of pushing the third portion onto the second portion will cause the chamber cutter to be moved downwards, thereby pushing the seal 203 and releasing the substance into the receptacle 209. Once the third portion is pushed and lowered onto the second portion 205, the third portion 207 is permanently mounted onto the second portion 205. This would prevent any movement between the components of the assembly 200. The locking mechanism is shown in Figure 9 where attachment means may be provided on each of the third portion 207, the second portion 205 and the chamber 202 to secure each of the components together once the substance has been released into the receptacle 209. For example, a vertical lip 216 may be present on the top of the second portion 205. The vertical lip 216 is configured to lock with a portion of the third portion 207 to prevent movement between the second portion and the third portion. In the embodiment shown in figure 9, a lateral projection on vertical lip 216 fits into a complementary shaped recess in a downwardly extending part 207A of third portion 207. A lateral shoulder 217 may be provided on the chamber 202 to prevent movement between the chamber 202 and first portion 201.

[00073] Similar to the previous embodiment, once the substance from the chamber 202 is released into the receptacle, the user will then mix the substance (e.g. infant formula powder) with the substance inside the receptacle (e.g. water) until both substances are combined. The user will the proceed to remove the protective lid 210 to feed the infant formula to the baby. If desired, the user can microwave or warm the substance in the receptacle to an appropriate temperature before feeding the baby.
