A. Opening Apparatus

[0048] The capsule (1) is suitable to be used in beverage preparation machines and comprises a receptacle (2) that has an orifice (3) enabling loading/unloading of the beverage raw material therein and at least one side surface (4) that surrounds the orifice (3).

[0049] The capsule (1) of the present invention is suitable to be used in the beverage preparation machine having an opening apparatus (A), and comprises a skirt (5) that surrounds the side surface (4) all around so that at least some portion thereof is seated on the side surface (4) almost without any gaps, a cover (6) attached on the skirt (5) so as to cover the orifice (3), and an opening (7) that remains between the side surface (4) and the skirt (5) and that enables the cover (6) to separate from the receptacle (2) by being seated on at least some portion of the opening apparatus (A). The skirt (5) is preferably seated on the side surface (4) from its lower side almost without any gaps and widens towards its upper side such that the opening (7) is formed between the side surface (4) and the skirt (5), thereby surrounding the side surface (4) that surrounds the orifice (3). Thus, when the receptacle (2) is viewed from above, the side surface (4) and the skirt (5) form a double walled structure. The cover (6) provides the closing of the receptacle (2) by being attached on the skirt (5) (FIG. 1 and FIG. 2).

[0050] The capsule (1) is preferably placed into the beverage preparation machine such that the opening (7) faces downward and the opening apparatus (A) is aligned with the opening (7). By means of an actuation mechanism (not shown) of the beverage preparation machine, the opening apparatus (A) and the capsule (1) are moved close to each other and the opening apparatus (A) enters the opening (7) by cutting/tearing some portion of the cover (6). In this case, the skirt (5) and the side surface (4) help the opening apparatus (A) to cut the cover (6) effectively by supporting the cover (6) from both sides. Due to the capsule (1) standing upside down, the beverage raw material, with its weight being on the cover (6), enables the cover (6) to open like a lid by folding over the uncut portion of the cover (6) by the gravity effect. Thus, almost all the beverage raw material in the receptacle (2) is enabled to be poured into the brewing chamber or the cup. By means of the skirt (5) and the opening (7) of the present invention, the opening apparatus (A) is not required to enter the receptacle (2). As the opening apparatus (A) enters the opening (7), the cover (6) is cut such that the side surface (4) surrounding the orifice (3) remains inside and thus the beverage raw material is not spilled on the opening apparatus (A). When the cover (6) is partially cut along the opening (7), the side surface (4) supports the cover (6), thereby prevents the cover (6) from folding over itself and almost all the beverage raw material inside the receptacle (2) is enabled to be poured. Furthermore, by means of the skirt (5), the opening apparatus (A) providing the cutting/tearing of the cover (6) is not required to be on the capsule (1) and improvement in capsule (1) costs is provided.

[0051] In another embodiment of the present invention, the upper side of the skirt (5) is lower than level of the orifice (3). In other words, preferably the upper side of the skirt (5) is at a lower level than the level of the side surface (4) sides that surround the orifice (3) in the vertical plane. Thus, the cover (6) attached to the skirt (5) are stretched by the sides of the side surface (4) and the beverage raw material is prevented from spilling into the opening (7) during the movement of the capsule (1) such as carrying (FIG. 4).

[0052] In another embodiment of the present invention, the skirt (5) surrounds at least some portion of the side surface (4) in the vertical direction. In this embodiment, the skirt (5) surrounds the side surface (4) so as to form a gap that enables the cover (6) to be cut and thus cost advantage is provided (FIG. 3).

[0053] In another embodiment of the present invention, the skirt (5) longitudinally surrounds the side surface (4). In this embodiment, the skirt (5) is connected to the receptacle (2) preferably from the base and is prevented from breaking and bending when the capsule (1) is placed into the beverage preparation machine and the actuation mechanism applies force on the capsule (1) from above (FIG. 2).

[0054] In another embodiment of the present invention, the skirt (5) is connected to the side surface (4). For example, the receptacle (2) and the skirt (5) produced separately are connected to each other by vibration welding or similar connection methods.

[0055] In another embodiment of the present invention, the skirt (5) and the side surface (4) are produced in an integrated manner. By means of this embodiment, the number of parts used is decreased by producing the receptacle (2) and the skirt (5) together and quality perception of the consumer is improved.

[0056] In another embodiment of the present invention, the capsule (1) comprises a housing (13) wherein the receptacle (2) is seated and the upper side of which is connected to the skirt (5). The receptacle (2) is seated into the housing (13) and the skirt (5) is connected to the housing (13) from its lower side. When the opening apparatus (A) enters the opening (7) by cutting the cover (6), the housing (13) tightly supports the skirt (5) from the lower side. The housing (13) and the skirt (5) are produced as a single piece and grasp the base of the receptacle (2), enabling the opening apparatus (A) to open the capsule (1) without problems by increasing the strength of the skirt (5) (FIG. 7, FIG. 11).

[0057] In another embodiment of the present invention, the receptacle (2) is seated into the housing (13) snap fittingly. In this embodiment, the housing (13) tightly surrounding the receptacle (2) increases the strength of the skirt (5) and the receptacle (2) is prevented from bending/folding when the capsule (1) is placed into the beverage preparation machine and opened by the opening apparatus (A).

[0058] In another embodiment of the present invention, the capsule (1) comprises a recess (8) that is arranged on the receptacle (2) or the housing (13) and a protrusion (9) that is disposed on the receptacle (2) or the housing (13) correspondingly and that is seated into the recess (8) by aligning with the recess (8) when the receptacle (2) is seated into the housing (13), the recess (8) and the protrusion (9) preventing the housing (13) and the receptacle (2) from being separated (FIG. 9, FIG. 10).

[0059] In another embodiment of the present invention, the capsule (1) comprises a protector (10) that extends from the side surface (4) outwards almost in a direction perpendicular to the side surface (4) so as to remain under the cover (6) and that prevents the beverage raw material from entering the opening (7). In other words, the protector (10) prevents the beverage raw material in the receptacle (2) from entering the opening (7) by partially closing the opening (7). The protector (10) is preferably connected to the side surface (4) in an easily foldable manner. While the capsule (1) is carried, the beverage raw material is prevented from entering the opening (7) from the sides of the receptacle (2) by the protector (10). When the capsule (1) is to be placed into the beverage preparation machine and opened, the protector (10) is folded towards the interior of the opening (7) thanks to the foldable connection when the opening apparatus (A) contacts the protector (10) in order to enter the opening (7) (FIG. 5).

[0060] In another embodiment of the present invention, the protector (10) is in the form of a plate having an intermittent configuration with the separate portions being spaced apart and surrounds the side surface (4). Thus, when the opening apparatus (A) enters the opening (7), the protector (10) easily folds into the opening (7).

[0061] In another embodiment of the present invention, the capsule (1) comprises a frame (11) that is disposed on the upper side of the skirt (5), that extends in a direction almost perpendicular to the skirt (5) and whereon the cover (6) is attached. The frame (11) also carries the weight of the capsule (1) when the capsule (1) is placed into the beverage preparation machine. The frame (11) enables the cover (6) to be airtightly adhered on the receptacle (2) and at the same time prevents the receptacle (2) from being crushed/bent when the capsule (1) is placed into the beverage preparation machine (FIG. 8).

[0062] In another embodiment of the present invention, the capsule (1) comprises a casing (12) wherein the receptacle (2) is seated so as to surround the receptacle (2) and the skirt (5), and that enables the beverage raw material to stay fresh for a longer period of time. The receptacle (2) and the skirt (5) are preferably produced by plastic injection method due to their configuration. Plastic that is produced by injection method is not entirely airtight and in this case the beverage raw material in the receptacle (2) cannot keep its freshness. By means of the casing (12) that is produced by plastic thermoforming method and has better airtightness in comparison to the receptacle (2), the beverage raw material is enabled to stay fresh for a longer period of time (FIG. 6, FIG. 12).

[0063] In another embodiment of the present invention, the skirt (5) extends parallel to the side surface (4). By means of this embodiment, when the capsule (1) is placed into the beverage preparation machine, even if it is not aligned completely, the opening apparatus (A) of the beverage preparation machine easily enters the opening (7).

[0064] In another embodiment of the present invention, the skirt (5) extends in an inclined manner with respect to the side surface (4). By means of this embodiment, the strength of the skirt (5) is increased, thus the skirt (5) is enabled to resist the force exerted by the beverage preparation machine when the capsule (1) is placed into the beverage preparation machine.

[0065] The beverage preparation machine of the present invention is suitable for using the above described capsule (1). The beverage preparation machine preferably comprises an opening apparatus (A) that provides the emptying of the beverage raw material in the capsule (1). The opening apparatus (A) enters the opening (7) by cutting the cover (6). The beverage preparation machine is preferably a Turkish coffee machine that can make Turkish coffee wherein the capsules (1) containing Turkish coffee are used.

[0066] In the capsule (1) of the present invention, by means of the skirt (5), the beverage raw material contained therein can easily be poured into the brewing chamber in the beverage preparation machine or into a cup without requiring cutting elements with complex structures for opening the cover (6) thereon. When the cover (6) is cut partially along the opening (7), the skirt (5) and the sides of the receptacle (2) support the cover (6) from inside the capsule (1) and help in opening of the cover (6) unproblematically.
