CONTAINER INFLATION SYSTEM AND A METHOD OF INFLATING A BALLOON USING THEREOFTECHNICAL FIELD
[0001] The present invention relates to a container inflator system, and particularly, although not exclusively, to a container inflator system arranged to inflate balloons or the like so as to allow objects to be placed within the balloon.BACKGROUND
[0002] Balloons are a common product which is enjoyed by children and adults alike. There are various versions of balloon toys including use of different materials to make the balloons, forming the balloon with different shapes or the use of lighter than air gases to inflate the balloons to create balloons that float so as to deliver a unique effect of a floating decoration.
[0003] One recent trend has been to inflate balloons with different toys or decorative items inside them such as confetti, glitter sheets, messages or even large items such as stuff toys or gift items. In turn, this improves the appearance or enjoy-ability of the balloon as well as turning a balloon into a unique gift. One such product is to insert decorative items within an inflated balloon such as LED lights, jewellery or toys. These items add to the interests of the balloons and can also change the effect of the balloon. Examples of such balloons may be to include festive lights into the balloon during Christmas, or romantic items such as flowers or rose pedals during seasonal displays, or the inclusion of soft toys for birthday or graduation parties.
[0004] However, the manufacturing of such balloons is complicated by the difficulty in the insertion of items into a balloon followed by the correct inflation of the balloon. Balloons typically have a elastic but narrow neck, meaning the insertion of items or objects into the balloons is difficult and cannot be achieved with simple means as it is difficult to insert objects within a balloon without tearing the balloon itself. Accordingly, the creation of such balloons that houses various toys or objects within typically require specialist equipment that are large and expensive. In turn, such balloons are typically created by specialist, balloon or party stores and thus increasing costs and reducing flexibilities for home hobbyists or makers such as for custom filled balloons for sale or as gifts and as activities such as for parties and with friends and family.SUMMARY OF THE INVENTION

[0035] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0036] Referring to Figures 1 and 2, there is illustrated an example embodiment of a container inflator system comprising: a suction chamber arranged to provide a cavity for expanding a container therein; a connecting member detachably coupled to the suction chamber allowing an opening of the container to be accessible for insertion of objects therein; a valve arrangement arranged to seal the container so as to maintain the expanded state of the container when it is removed from the suction chamber; and an inflation apparatus arranged to further inflate the container when the container is removed from the suction chamber.
[0037] In this embodiment, the container inflation system 100 includes a suction chamber 102 which is arranged to firstly expand a container (not shown) . The container may preferably be a balloon although other types of containers are also possible. The balloon may also include various inflatable type containers including balloons or vessels of various colours or shapes or made from various materials such as elastic plastics or metallic foils. The suction chamber 102 is formed by a dome member 104 detachably engaged with a base portion 106. A O-ring 105 may be provided on the base portion 106 to minimize air leakage between the dome member 104 and the base portion 106. The dome member 104 and the base portion 102 thereby create a cavity for a container such as a balloon or other inflatable object to be placed therein for expansion when there is a suction pressure applied. The suction pressure is applied by using an inflatable apparatus 108 connected to the suction chamber 102. This in turn causes the balloon to substantially expand along the wall of the dome member 104 due to the suction pressure. When the container is expanded, this in turn expands the volume of the container and the width of the opening (e.g. the neck of the balloon) such that a user may introduce objects or decorative items (not shown) into the container to make a “stuffed” container or balloon.
[0038] In particular, the system 100 further includes a connecting member 110 which is detachably coupled to the dome member 104 such that the container may be mounted on the connecting member 110 before or after the connecting member 110 is coupled to the suction chamber 102. As shown in Figures 1 and 2, the suction chamber 102 is coupled with a connecting member 110 which acts as an adaptor for connecting to the container. The opening of the container can be stretched around the connecting member 110 allowing an opening for insertion of objects therein when the container is expanded.
[0039] In this example, the connecting member 110 extends outward from the suction chamber 102 allowing a user to fit a container easily on the connecting member 106. The connecting member 110 may further include a O-ring 120 for sealing between the connecting member 110 and the suction chamber 102 to prevent air leakage at the suction chamber when a suction pressure is applied. In this example, the connecting member 110 is coupled to the suction chamber 102 by screw fit. A user may then insert the connecting member 110 into the suction chamber 102 and twist it for proper engagement. It would be appreciated that other possible engagement mechanism or means may also be applied to removably attach the connecting member 110 to the suction chamber 102. For example, the connecting member 110 may include a snap fit arrangement or a magnetic element to interact with another magnetic or metal element arranged on the suction chamber for proper engagement. This is advantageous in that the connecting member may be easily detached from the suction chamber for further manipulation of the container, so as to minimize any physical damages that could be caused to the container, especially to the opening of the container during the inflation process which in the case of dedicate balloons, any manipulation after its partial inflation to extract it from the suction chamber 102 risks tearing the balloon wall or the balloon beck, resulting in the balloon having to be replaced.
[0040] As shown in Figures 1 and 2, the system 100 further includes a valve arrangement 130 arranged to seal the container so as to maintain the expanded state of the container when it is removed from the suction chamber 102. In use, the valve arrangement 130 is positioned on the connecting member 110 to close the opening of the container. In this example, the valve arrangement 130 includes a body 132 having an inlet 134 configured to connect to the inflation system 108 or any inflator such as a pump for delivering an inflation pressure to the coupled container. Preferably, the valve arrangement 130 includes an annular member 136 arranged to engage with the opening of the container seated on the connecting member 110. The annular member 136 is then mounted on a base plate 138 which is configured to have an air channel 140 for delivering an inflation pressure into the container. In this example, a one-way valve 142 is positioned in the air channel 140 for unilateral air flow through the valve arrangement 130. This is advantageous in that the container may maintain its air pressure and thus its expanded state when the inflation pressure is temporarily paused.
[0041] As shown in Figure 2, the valve arrangement 130 also includes an O-ring 144 at the inlet on the body 132 to form a seal between the valve arrangement 130 and the inflation apparatus 108 when an inflation pressure is delivered. In this example this coupling is made by fitting the inlet 134 into the receiving hole in the centre of base portion 106 and an airflow connector 172. The conduit 160 is then coupled to the airflow connector 172 and the inflation apparatus 108.
[0042] In this example, another O-ring 146 may also be arranged at the waist of the annular member 136 to further improve the air tight seal, whereby when the valve arrangement 130 is used to close the opening of the container and form a seal with the connecting member 110, it forms an airtight seal to the container.
[0043] The valve arrangement 130 further includes a fastening mechanism 150 arranged to secure the valve arrangement 130 to the connecting member 110, thereby forming a tight seal. The fastening mechanism 150 is provided to keep the opening of the container in place between the valve arrangement 130 and the connecting member 110, such that a user can easily detach the connecting member 110 together with the container from the suction chamber 102 while keeping the expanded state of the container. In an embodiment, the fastening mechanism 150 includes at least one male and at least one female element for locking. In the example as shown in Figures 1 and 2, the fastening mechanism 150 includes two locking pieces 152, 154, and each of them has a male and female part for complementary coupling with the corresponding female and male part on the other locking piece 152, 154. A user can apply a force to release the locked pieces 152, 154. It would be appreciated that other possible fastening mechanisms or means are also suitable for this purposes. For example, a mounting clip, magnetic fasteners, or the like.
[0044] As shown in Figure 1, the inflation apparatus 108 is connected to the suction chamber 102 to deliver a suction pressure so as to expand the container inside the cavity of the suction chamber 102. In this example, the inflation apparatus 108 includes a pumping device having two gas ports A, B for delivering a suction pressure and an inflation pressure via a conduit 160. This is advantageous as the usage of the same pumping device reduces the size and complexity of the container inflator system 100 whilst also reducing the costs of manufacturing the system. The pumping device is arranged to have a cylindrical shape as such it can be placed upside down depending on the preferred pressure for application.
[0045] In this example, the pumping device provides a suction pressure to the suction chamber 102 by delivering it through port A. When the container is removed from the suction chamber 102 and ready for further inflation, the pumping device is able to deliver an inflation pressure through port B by connecting the container to the port B via a conduit 160. In this example, the pumping device is a manual pumping device. It would be appreciated that an electric pumping device may also be implemented in some examples.
[0046] As shown in Figures 1 and 2, the container inflation system 100 further includes a chamber holder 170 arranged to hold the suction chamber 102 in place. In an example, the chamber holder 170 is in fluid communication with the inflation apparatus 108. The chamber holder 170 is arranged to allow the delivery of pressure in and out from the cavity or the container. For example, when a suction force is applied, the chamber holder 170 can hold the suction chamber 102 in place. At a second stage of inflating the container, a user can connect the container directly to the chamber holder 170 which is now arranged to facilitate an inflation pressure to the container via an airflow connector 172. This is advantageous in that a user may easily inflate the container by placing it in the chamber holder without manually holding it during the entire inflation process. It also facilitates subsequent manipulation of the container, e.g. sealing the container by using a rubbery ring, a soft seal or a string.
[0047] In an embodiment, the dome member 104 of the suction chamber 102 may further include a plurality of gripping regions 180, allowing a user to apply a force on it so as to release either the dome member 104 from the base portion 106, or the connecting member 110 from the dome member 104. The gripping regions 180 could be protrusions extending outwards from the wall of the dome member 104. It would be appreciated that the gripping regions 180 could be configured in different manner facilitating the detachment, such as soft gripping patterns on the wall of the dome member 104.
[0048] With reference to Figures 3 and 4, there is demonstrated a method to inflate a balloon by using the container inflation system 100. The method includes steps of
[0049] - coupling a connecting member to a suction chamber, and expanding a balloon in the suction chamber;
[0050] - coupling a valve arrangement to the connecting member to maintain the expanded state of the balloon, and
[0051] - further inflating the balloon by delivering an inflation pressure to the balloon by using an inflation apparatus.
[0052] Initially, as shown in Figure 3, the connecting member 110 is inserted into the suction chamber 102 and extrudes from the suction chamber 102 providing a surface for a balloon 190 to stretch around its neck. The suction chamber 102 is positioned on the chamber holder 170 firmly. A user then stretches a balloon 190 around the neck of the connecting member 110. By connecting the chamber holder 170 to the inflation apparatus 108, a suction pressure is then created to expand the balloon 190 towards the inner wall of the suction chamber 102, creating a cavity inside the balloon 190 for introducing any objects or decorative items (not shown) into the balloon. In other words, the method may further include a step of introducing objects into the balloon when it is expanded.
[0053] After the objects (if any, as desired by the user) are inserted into the cavity, the valve arrangement 230 (a simplified representation of the valve arrangement 130 in Figure 1) is positioned on the opening of the balloon to maintain its expanded state. In an example, a fastening member (as discussed above, and not shown) is applied to keep the valve arrangement 230 and the connecting member 110 in place. The fastening member, e.g. a fastening clip, is positioned to mount on both the connecting member 110 and the valve arrangement 230 so as to keep the balloon 190 air tight. The balloon 190 can then be removed from the suction chamber 102 by twisting the gripping regions 180 of the suction chamber 102 so as to release the connecting member 110 from the engagement. As shown in Figure 4, the balloon 190 with the connecting member 110 as well as the valve arrangement 230 is then removed from the system. The user can apply a soft seal like a wire tie, string or elastic band to tie up the balloon 190 if needed.
[0054] Alternative, the user can continue to inflate the balloon 190 to a larger size by fitting the inlet of the valve arrangement 230 into the chamber holder 170, or connecting the inlet to the inflation apparatus 108 to deliver an inflation pressure to inflate the balloon 190 further. If desired, the user may also fit the inlet of the valve arrangement 230 to a separate inflation pump device that the user may have on hand, such as a helium tank or other gas source. This is particularly useful as the present valve arrangement 230 and the operation of some embodiments of the container inflation system may allow a user to create a stuffed balloon, followed by inflating it with an alternative gas such as helium to create a “floating” balloon. This is because the originally filling process, will partially inflate the balloon to allow the stuffings to be inserted, but in turn will allow the filled balloon to be further inflated with a lighter than air gas (or other gases as preferred) so as to create the desired effect. In turn, where the balloon size allows for a sufficient amount of lighter than air gases to be used to inflate it to overcome the weight of any stuffings and air that are left inside the balloon, the user may be able to create not just “stuffed” balloons (e.g. balloons with objects within it) , but also floating stuffed balloons (e.g. balloons which will float and also have objects within it) and thus offering more variety of balloons that may be created without the use of complex or dedicated equipment.
[0055] After inflation, a user may then proceed to seal the balloon 190 such that the balloon 190 may retain the air pressure within it when the inflation pressure is removed. One possible method to perform this is by sealing the balloon with any sealing mechanism such as a ribbon or string tied around the balloon, or even by use of the user’s digits, at the neck of the balloon, i.e. below the connecting member. As shown in Figure 4, a string 192 is applied to seal the balloon 190 although other sealing mechanisms, such as elastic bands, or even heat seals may be used. The neck of the balloon may also be stretched, twisted and looped into a knot to form and air tight seal.
[0056] After the seal 192 is applied, the valve arrangement 230 along with the connecting member 110 can then be disengaged from the balloon 190 by unlocking the fastening member (not shown) . The valve arrangement 230 and the connecting member 110 may be used to inflate another balloon. A user may easily handle the entire inflation process without much manual burden or complex manipulation, and such a system minimize the risk of causing damages to the balloon during the filling, inflation or sealing process.
[0057] Referring to Figure 5 and 6, there is illustrated another embodiment of the container inflation system 300. The container inflation system 300 includes a spherical suction chamber 302 formed by two semi-sphere parts 304’, 304”, a connecting member 310 to be coupled to the suction chamber 302, a valve arrangement 330 to be positioned on the connecting member 310 for sealing a balloon 390. It would be appreciated that the connecting member 310 may correspond to the connecting member 110 as shown in Figures 1 and 2; and the valve arrangement 330 may correspond to the valve arrangement 130 in Figures 1 and 2, or may be in a simpler design mainly with a one-way valve. In this embodiment, an electric pumping device (not shown) or a manual pumping device could be applied to create air pressure.
[0058] In this embodiment, the suction chamber 302 further includes a one-way valve (not shown) allowing air to be expelled out from the suction chamber 302 when inflation pressure is applied to the balloon directly, thereby creating a vacuum between the balloon 390 and the suction chamber 302. As such, when inflation pressure is removed, the balloon 390 is kept at the expanded state for further manipulation such as introduction of decorative items.
[0059] In use, a user may firstly place the balloon 390 into the suction chamber 302 with its opening sealed around the connecting member 310. Then, the valve arrangement 330 having a one-way valve (not shown) may be placed to close the opening of the balloon 390. Next, the user may directly connect the inlet of the valve arrangement 330 to a pumping device for inflation. After inflation, the pumping device and the valve arrangement 330 may be removed while maintaining the balloon 390 at the expanded state.
[0060] If desired, the user can continue to inflate the balloon to its maximum size after adding objects into the balloon 390. The maximum size of the balloon 390 will be limited to the size of the suction chamber 302.
[0061] To seal the balloon 390, the valve arrangement 330 is used, again, to close the opening of the balloon 390. A fastening member (not shown) which corresponds to the fastening member 150 may be used to hold the connecting member 310 and the valve arrangement 330 in place. To disengage the connecting member 310 along with the valve arrangement 330 and the balloon 390 from the suction chamber 302, it is preferred to relieve the negative pressure in the suction chamber 302 before applying force to open the suction chamber 302 so as to minimize any unwanted damages to the balloon 390. Subsequently, the user can seal the balloon easily in the presence of the valve arrangement 330.
[0062] It would be appreciated that a simpler valve arrangement 330, for example by containing a one-way valve in the absence of a fastening mechanism, may be applied. It would also be appreciated that the valve arrangement 330 and the connecting member 310 of the present invention are suitable to be used with other container inflation system to seal the container tightly for manipulation.
[0063] It would be appreciated that the connecting member, as described herein (110 and 310) , may be configured in different manner to suit for different embodiments to allow easy fitting, inflation and removal of the container from the apparatus and sealing it.
[0064] The present example embodiments of the container inflation system 100, 300, may be advantageous as it is able to assist users to make a “stuffed” balloon without complex equipment. The system 100, 300 is easy to use, compact to store and transport and low cost to manufacture. In turn, rendering the system 100, 300 practical as a domestic product for children and adults.
[0065] It will be appreciated by persons skilled in the art that numerous variations and / or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
[0066] Any reference to prior art contained herein is not to be taken as an admission that the information is common general knowledge, unless otherwise indicated.
