Definitions

• the present invention relates to a fitment for connecting a container to a dispensing appliance. It further relates to a dispensing device comprising a container and dispensing means, having an improved fitment system between said container and said means.
• a system In order to dispense viscous edible products such as eg. soft ice cream, a system was developed recently which comprises a support with pump means for generating compressed air, and a container for storing and dispensing the said ice cream.
• the container can then receive compressed air that is used to push the product outside.
• the pump means present on the support are operated preferably manually by the consumer at the time of dispensing.
• the container preferably comprises multi-layer walls, i.e. walls having at least two layers, which are not bound to each other, so that compressed air pumped from the support pumplugg means, is directed in between the said unbound layers.
• Product to dispense is contained inside the most internal wall layer.
• product is pushed outside by deformation of the inner wall layer, as compressed air fills the space in between the wall layers of the container.
• a consumer tries to fill compressed air into a bottle with another pump means than that specifically designed for use in the original dispensing system.
• a consumer could use a compressed gas cartridge such as those used generally for preparing whipped cream, or gas water, a bicycle pump, an electric compressor, or similar, which would deliver a much higher pressure in between the container wall layers. This would not only damage the container, but would present a risk of explosion of the said container, that could harm the consumer.
• the consumer could be tempted to connect a bottle filled with a product, that is not intended for use (i.e. was not designed to be used) with the original support and pump means, leading to the same damages and risks as described above, which are clearly undesirable to the consumer.
• At least one container containing said edible product said container having walls with at least two layers such that when said container is connected to said support and said means are operated to generate compressed gas, said compressed gas fills the space between said layers so as to press said product out of said container.
• the dispensing device is characterized in that it comprises fitment means for establishing a fluid connection between said container and said support in a removable and leak-tight manner, said fitment means comprising: - at least one cylindrical, conical or frusto-conical orifice located on the container or on the support, said orifice having an ovoid cross-section and comprising at least one groove or protrusion disposed parallel the longitudinal axis of said orifice,
• the present invention is directed to a fitment for establishing a leak-tight fluid communication between a support having means for generating compressed gas, and at least one container containing an edible product that is to be connected to said support, characterized in that said fitment comprises:
• At least one cylindrical, conical or frusto-conical orifice located on the container or on the support, said orifice having an ovoid cross-section and comprising at least one groove or protrusion disposed parallel the longitudinal axis of said orifice, (ii) a one-way valve to allow compressed air generated by the gas- compression means only in the way from said support to the container,
• said orifice comprises at least three grooves, or at least three protrusions.
• said orifice is located on the container bottom, and the plug is located onto the support.
• said orifice or said plug can advantageously comprise at least one
• O-ring made of rubber or similar sealing material, said O-ring being disposed inside said orifice, respectively around said plug, such that the space between the inner walls of the orifice and the outer walls of the plug is gas-tight when said plug is fully inserted into said orifice.

• figure 9B is a an enlarged partial view of the fitment shown in figure 9A.
• the fitment according to the present invention is intended for use in a dispensing device 1 as illustrated in figures 1 or 2.
• the dispensing device 1 is suitable for the delivery of at least one edible product (not shown in the drawing), preferably at least one viscous frozen edible product, like for instance a soft ice cream composition.
• the device 1 comprises a support 2 having means 3 for generating compressed gas.
• These compression means comprise a handle 3, linked to a pump (not shown in the drawing) that is disposed inside a casing 4.
• the support 2 further comprises a recess shaped so that a container 5 can be assembled to the support in a removable manner, as illustrated in figures 1 and 2.
• the container 5 is for containing said edible product, and as illustrated in figure 4, it has walls with two layers, one inner layer 6 containing said edible product, and an outer layer 7. It further comprises a dispensing opening 8 shown for instance in figure 3. In operation, the dispensing opening 8 of the container 5 is closed by a tap 9, or similar closing device that allows a consumer to manually open or close said opening to dispense a given volume of ice cream, into a portion container (cup, edible cone, etc.).
• the dispensing device When said container 5 is connected to said support 2, a fluid communication is established between these two parts of the dispensing device 1 , as will be described in detail hereafter.
• the compression means 3 are then operated by the consumer to generate compressed gas, said compressed gas fills the space between said inner 6 and outer 7 layers of the container walls, such that a gas pressure is generated in the space between said inner 6 and outer 7 layers of the container 5.
• the consumer can then open the tap 9 so that said inner layer 6 deforms under gas pressure, and is displaced towards the container opening 8.
• the said inner layer 6 therefore presses onto said product that is pushed out of said container through said dispensing opening 8 and tap 9.
• the dispensing device is characterized in that it comprises fitment means 10 for establishing a fluid connection between said container 5 and said support 2 in a removable and leak-tight manner.
• the said fitment means 10 comprise firstly, one frusto-conical orifice 1 1 located on the container, more particularly, on a base portion 12 of the container 5.
• the said base 12 is particularly well represented in figures 3 to 6.
• the base 12 is assembled as a separate element to the bottom side of the container 5. Like the container 5, it is preferably made out of a thermoplastic, food-grade, material.
• the base 12 comprises a channel 13 to conduct compressed air from the compression means to the space in between the inner 6 and outer 7 layers of the container walls. Towards the outside, the channel 13 of the base 12 is opened through the orifice 1 1 , as illustrated in figure 6. On the other end, the channel 13 is connected to the inside of the container 5 in a leak-tight manner.
• the channel 13 comprises a oneway valve 14 made out of a synthetic flexible material, for instance an umbrella valve as illustrated in figure 6, that allows compressed air generated by the compression means of the support 2, to pass through said channel 13 towards the inside of the space between said inner 6 and outer 7 layers of the container walls, said valve 14 being deformable and/or movable inside said channel, such that it prevents compressed air to pass through said channel from said container 5, back to the support 2.
• a synthetic flexible material for instance an umbrella valve as illustrated in figure 6, that allows compressed air generated by the compression means of the support 2, to pass through said channel 13 towards the inside of the space between said inner 6 and outer 7 layers of the container walls, said valve 14 being deformable and/or movable inside said channel, such that it prevents compressed air to pass through said channel from said container 5, back to the support 2.
• the present invention could be structured with a ball-valve, duckbill valve, or equivalent one-way valve.
• the fitment orifice 1 1 has an oval cross- section and comprises four grooves 15 disposed parallel the longitudinal axis of said orifice. Two consecutive grooves are spaced apart from one another along the circumference of the orifice 11 , by a 90° angle, as cam be seen in detail in figures 7B and 9B.
• the grooves extend from the outside edge of the orifice 11 , into at least half of the depth of the latter, as can be seen in figure 7B.
• These grooves have a width and depth of at least 0.5 mm, preferably of at least 1 mm each.
• the specific oval shape of the orifice prevents the introduction of a pipe or other similar tool having a round cross-section, that could be used for introducing compressed air into the orifice 1 1 and channel 13, and that could lead to damages to the whole device or even create a risk of explosion of the container which would be clearly unacceptable to the consumer.
• the grooves 15 ensure that even though a consumer would manage to introduce a flexible pipe or oval-shaped pipe into the orifice 1 1 , compressed air will leak through the grooves back to the atmosphere, so that the container cannot be inflated by another air-compression system than that specifically designed for use with the multi-layer container described hereinabove, thus reducing the risk of explosion or otherwise damage of the container as hereinbefore mentioned.
• the support 2 of the dispensing device 1 further comprises one plug 16 that substantially corresponds in shape and dimensions to the orifice 1 1 of the container base portion 12.
• the plug 16 of the fitment means 10 is shown separate from the compression means of the support 2, however, the said plus in normally part of the whole support 2, and in fluid connection with the outlet of the pump compression means (not shown in the drawing).
• the fitment means 10 is therefore made of orifice 11 and plug 16.
• the plug 16 has an oval shape that corresponds to that of the orifice 1 1 , so that said plus can fit perfectly in said orifice as shown in figures 9A and 9B.
• said plug 16 comprises an O-ring 18 made of rubber or similar sealing material, said O-ring 18 being disposed around said plug 16, such that the space between the inner walls of the orifice and the outer walls of the plug is gas-tight when said plug is fully inserted into said orifice.
