Description

[0002] The present invention relates to a container equipped with a device enabling a beverage to be absorbed in a hygienic manner preventing the consumer from placing his lips on an external portion of said container, and more particularly to the device for extracting a straw from the container.

[0003] Numerous containers are commercially available: plastic bottles, glass bottles, metallic cans, cardboard packagings, which can have various shapes allowing for the packaging of any type of liquid food products.

[0004] These various containers have the disadvantage, for the user, of being either unhealthy when one wishes to drink straight from the container, or impractical depending on the shape and size of the neck, or the very shape of the container itself.

[0005] In the particular case of metallic cans and cardboard packagings used for diverse and varied beverages, such as beers, sodas, fruit juices, or milk, they are very unhealthy. Indeed, from the locations where they are produced, after the beverage has been packaged, they are transported and unloaded without any specific hygienic measure, and then sold to the consumer by a retailer who stores them without any particular hygienic precaution and handles them manually. During these various manipulations, various microbes, viruses, bacteria or dust can be deposited on the walls of the container, which are ingested by the consumer when he places his lips on the container.

[0006] Furthermore, in the particular case of metallic cans, and independently of hygiene problems, the consumer can be hindered when drinking the beverage by problems of ill-timed flow, which most often leaves stains on his clothes.

[0007] In order to avoid said disadvantages, the invention proposes to resolve these practical and hygiene problems by simple and inexpensive means, due to a device for automatically extracting a straw located within the container.

[0008] Thus, according to its main characteristic, the device for automatically extracting a straw arranged within a container, such as a cylindrical can provided with opening means, for example, is characterized in that it comprises:

[0009] a straw-supporting element mobile between a free position in which the straw which it supports has its end in the orifice of the container opening means and a locked position in which said end is arranged within the container,

[0010] means for stressing the straw-supporting element adapted to bias the latter from its locked position toward its free position,

[0011] locking means adapted to lock the straw-supporting element in its locked position,

[0012] releasing means adapted to release the supporting element from its locked position.

[0013] According to a complementary characteristic, the device for automatically extracting a straw according to the invention is characterized in that the actuation of the container opening means controls the actuation of the releasing means which release the straw-supporting element.

[0014] According to another characteristic, the straw-supporting element is constituted by a supporting arm provided with straw-retaining means at its end, said arm being articulated between its free position and its locked position on an independent intermediate piece affixed to the container.

[0015] According to the preferred embodiment of the device for automatically extracting a straw according to the invention, the means for stressing the straw are constituted by the articulation of the straw-supporting arm on the independent intermediate piece and/or by the arm itself, and are obtained due to the flexibility and elasticity of the material used to make the arm, the piece, and the articulation which connects them.

[0016] According to an embodiment of the device for automatically extracting a straw, the locking means are constituted by a secondary locking arm which has, at its end, an assembly of abutment surfaces adapted to cooperate with complementary support surfaces carried by the straw-supporting element when the latter is in the locked position.

[0017] According to this embodiment, the releasing means are constituted by a releasing lug carried by the secondary locking means and adapted to cooperate with the container opening means to cause the displacement of the secondary arm toward an extreme release position in which its abutment surfaces no longer cooperate with the complementary support surfaces of the straw-supporting element.

[0018] According to a complementary characteristic of the device for automatic extraction according to the invention, the straw-supporting element, the stressing means, the locking and releasing means are constituted by a single piece called the independent intermediate piece.

[0019] According to the preferred embodiment of the device for automatically extracting a straw according to the invention, the independent intermediate piece is in the form of an annular ring adapted to be arranged beneath the upper wall or cover of a container in the form of a cylindrical can.

[0020] According to this embodiment, the intermediate piece comprises sealing means adapted to make it possible to obtain sealing between the cover and the peripheral wall of the can, said means being adapted to be implemented during their assembly.

[0021] Furthermore, the invention also relates to a container for beverage, of the type comprising a device for automatically extracting a straw, such as those described hereinafter.

[0046] It is noted that to allow for a better understanding of the various Figures, the straw is not shown in FIGS. 4, 5b, 6b, 7a, 8, and 10; only the means for retaining the straw-supporting element are shown.

[0047] The invention relates to a device for automatic extraction generally designated by the reference numeral (1) adapted to automatically extract, when it is being opened, a straw (2) arranged within a container (3). The extraction device (1) is advantageously described in the particular case of metallic cylindrical cans whose opening means (MO) consist, in a manner known in itself, of a push ring (6) and a precut tongue (7) which can pivot toward the inside of the container (3) under the effect of the ring to free the orifice (5) of said opening means, as shown in FIGS. 1 and 2. It is understood that the device for automatic extraction according to the invention could be modified to be adapted to other types of containers or other types of opening means without leaving the scope of protection of the invention.

[0048] According to the invention, the device (1) for automatically extracting the straw (2) comprises a straw-supporting element (4) that is movable between a locked position (B), in which the straw (2) is located within the container (3) and which corresponds to the closed position of the opening means (MO), and a free position (A), in which the supporting element (4) presents the end (2a) of the straw (2) at the level of the orifice (5), and which corresponds to the open position of said opening means. The device also comprises means (MS) for stressing the straw-supporting element (4) which tend to cause it to displace from its locked position (B) toward its free position (A). Furthermore, locking means (MV) adapted to lock the straw-supporting element (4) in its locked position (B) and releasing means (MDV) adapted to cause the release of said element are provided. Moreover, the releasing means (MDV) are advantageously obtained so as to be actuated by the opening means (MO) of the container (3) when the consumer opens the orifice (5).

[0049] According to the preferred embodiment of the extraction device according to the invention, the straw-supporting element is constituted by an arm (4) carrying, at its end (4a), means for retaining the straw (2) such as a tube portion (10) within which the end (2a) of said straw is arranged. The straw-supporting arm (4) is advantageously articulated on an independent intermediate piece (9) arranged within the container and affixed thereto due to fixing means that will be described hereinafter.

[0050] According to this preferred embodiment, the locking means (MV) shown in FIG. 4 are advantageously constituted by a locking element such as a secondary locking arm (8), for example, which has, at its end (8a), an assembly of abutment surfaces (11), namely, two lateral abutments (11a, 11b), and a lower abutment (11c). The lateral (11a, 11b) and lower (11c) abutment surfaces are adapted to cooperate with complementary support surfaces (12, 12a, 12b, 12c) carried by the straw-supporting arm (4) when the extraction device (1) is in the locked position (B). The secondary arm (8) is advantageously articulated at its other end on the independent intermediate piece (9); however, it is understood that it could very well be articulated on another piece affixed to the can (3).

[0051] According to the preferred embodiment of the device (1) for automatically extracting the straw, the intermediate piece (9) is made out of a material that is slightly flexible and has a certain elasticity. Since the supporting arm (4) and secondary arm (8) are constituted by extensions of the intermediate piece (9), their articulation therewith occurs along a hinge (13, 14) formed, in a known manner, by a narrowing of the section of the extensions forming the arms, for example. The elasticity of the material used enables the articulated arms (4, 8) to be biased elastically toward their respective initial positions which each correspond to the free position of the extraction device (1), as shown in FIGS. 5b and 6b. The elasticity of the straw-supporting arm (4) constantly tends to bring it back to its free position (A) and thus constitutes the stressing means (MS) of the extraction device (1). However, said means could be obtained by any equivalent elastic return device, such as located, for example, on the hinges or articulations of the arms, without leaving the claimed scope of protection of the invention.

[0052] According to the preferred embodiment of the extraction device (1), the bias of the articulated arms (4, 8), due to the elasticity of their materials, when they are bent in the locked position (B), enables the respective abutment and support surfaces (11, 12) to cooperate against return forces that are exerted on said arms according to a known flying buttress principle shown schematically in FIG. 3a. Thus, the assembly of said support and abutment surfaces makes it possible to position and maintain the articulated arms, and essentially the straw-supporting arm (4) in a locked position (B), as shown in FIGS. 5a and 6a, in which the end (2a) of the straw (2), which it carries, is retracted within the can (3), and where the straw-supporting arm (4) is biased toward its free position (A) due to its elasticity and to its bent position.

[0053] It is noted that, according to the preferred embodiment of the device, the articulation (13) of the supporting arm (4) is obtained such that it passes from its locked position (B) in which the end (2a) of the straw (2) is located in a horizontal plane (H1) located beneath the horizontal plane (H) comprising the orifice (5) and offset with respect to this orifice, as shown in FIGS. 3a and 7a, toward a free position (A) in which the end (2a) is arranged in a plane (H2) located slightly above the plane (H) of the orifice, plumb therewith, as shown in FIGS. 3d, 7b, 8b and 10. The displacement of the supporting arm (4) thus occurs by pivoting in an inclined plane orthogonal with respect to the axis of its articulation (14) SO as to allow for the passage of the end (2a) of the straw (2) in the orifice (5).

[0054] The extraction device (1) also comprises releasing means (MDV) which make it possible, when the opening means (MO) of the container (3) shown schematically in FIG. 3b are actuated, to release the supporting arm (4) from its locked position (B). According to the preferred embodiment, the releasing means are constituted by a releasing lug (15) arranged on the secondary locking arm (8) and adapted to be actuated during the opening of the container by the pivoting, toward the inside of the can (3), of the precut tongue (7) or lid of the opening means so as to cause the displacement, by pivoting about its articulation (14), of the secondary arm toward an extreme releasing position (D) shown schematically in FIG. 3b. The pivoting of the secondary arm toward its releasing position (D) makes it possible to release the assembly of complementary abutment and support surfaces (11a, 11b, 11c, 12a, 12b, 12c) which cooperated with one another in the locked position (B), such that the straw-supporting arm (4) is returned toward its free position (A) by the stressing means (MS), as shown in FIG. 3c, the releasing lug then ceasing to cooperate with the precut tongue so as to also free the secondary arm.

[0055] Furthermore, according to the preferred embodiment, the secondary unlocking arm (8) is also biased toward its free position (A) by complementary stressing means also obtained by the elasticity of the material used to make it, or by elastic return means located on the articulation (14) of the arm on the intermediate piece (9). During the releasing, the secondary arm (8) passes above the supporting arm (4) to release the support and abutment surfaces of the two articulated arms which cooperate. Then, the two arms are each subject to a return force from their respective stressing means and come to position themselves in the free position. It is noted that the secondary unlocking arm (8) overlaps the supporting arm (4) to pass beneath and thus make it possible, due to its specific return force, to also bias the supporting arm (4) toward the top (HA) in a manner so as to bring it toward its free position (A).

[0056] It is noted that the articulated arms (4, 8), the means for retaining the straw (2), the supporting arm (4), the support and abutment surfaces, the secondary arm (8), and the intermediate piece (9) are advantageously made integral and form a single piece which is in the form of an annular ring (9) adapted to be arranged in the interior (INT) of the can (3), beneath the upper wall (16) on which the opening means of said can are arranged, as shown in FIG. 8a.

[0057] According to the preferred embodiment of the invention, the annular ring (9) is made of a plastic material of the type used in the food industry, so that it can be placed in contact with the liquid intended to be consumed. It can be advantageously obtained by an injection process, or by any other equivalent method.

[0058] It is also noted that the straw (2) can be constituted by two coaxial straw portions (20a, 20b), one (20a) of which is retained by the retention means (10) of the straw-supporting arm (4), and the other (20b) of which slides within the first (20a), as shown in FIG. 10, and thus enables the user to extract a portion thereof to drink while maintaining the lower end (2b) of the straw portion (20a) at the bottom (17) of the container (3) to enable the entire content thereof to be drawn up. The upper straw portion (20b) can advantageously comprise a retaining annular flange (18) adapted to prevent the latter from sliding entirely in the lower portion (20a). The flange (18) is located on the straw portion (20b) such that its upper end (2a) is located slightly above the plane (H) of the orifice (5) when the extraction device (1) is in the free position (A).

[0059] It is important to note that the annular ring (9) can advantageously comprise sealing means constituted by its peripheral edge (19). Thus, during the packaging of the can (3) with its extraction device (1) shown in FIGS. 9a and 9b, the peripheral edge (19) can advantageously replace the silicone joints used by manufacturers to ensure imperviousness between the peripheral wall (21) of the can and its upper wall (16), said edge being pinched between the two walls when the latter are assembled to one another by crimping, for example, as shown in detail in FIG. 9c. Thus, according to the various embodiments, the extraction device is constituted by an independent piece (9) that can be arranged and fixed in the container, and in particular in a can, without requiring any structural modification thereof.

[0060] Furthermore, according to the various embodiments of the extraction device, the annular ring (9) constituting it can advantageously be obtained by an injection process of the dual-material type, so as to obtain a piece made of a first relatively rigid plastic material provided with a peripheral edge (19) made of a second, more flexible plastic material injected simultaneously in a known manner. Thus, during the positioning of the device in the can, the relatively flexible peripheral edge makes it possible to obtain a perfect sealing between the upper wall (16) and the peripheral wall (21) of the can (3) as shown in FIG. 9c, whereas the relative rigidity of the main central piece enables the optimum functioning of the device, and especially the elastic bias of the arms from their locked position (B), in which they are in a slightly bent position, toward their free position (A).

[0061] According to a second embodiment shown schematically in FIG. 11, the extraction device (1) comprises a straw-supporting arm (4) of the type described in the preceding embodiment, articulated and biased toward its free position (A). However, the locking means (MV) are no longer constituted by a secondary arm, but by an abutment system (22) in the form of a catch affixed to the intermediate piece (9) on which the supporting arm (4) can be arranged in the locked position (B), said arm being biased by its stressing means (MS) toward its free position (A).

[0062] According to this embodiment, the releasing means (MDV) are constituted by a releasing lug (23) formed by a projecting wall portion of the straw-supporting arm (4). This lug (23) is adapted to cooperate with the precut tongue (7) of the can opening means (MO) when the latter pivots inwardly to release the supporting arm (4) of its abutment (22) against the bias of the stressing means (MS). When said arm (4) has come out of its catch and the releasing lug has stopped cooperating with the precut tongue (7), the stressing means return the arm toward its free position.

[0063] It is noted that, according to this embodiment, the release of the arm (4) which occurs by means the releasing lug (23) makes it possible to provide the arm with a potential energy greater than that which it has in the locked position, since the arm (4) is displaced against the return force of the stressing means (MS) by a height that is necessary to pass the catch; the abutment (22) thus makes it possible to provide the arm (4) with a complementary energizing so as to facilitate its positioning in the free position (A) when it frees itself from said abutment. It is noted that the lateral edge (22a) of the abutment (22) can advantageously be inclined and slightly incurved and, as a result, can constitute means for guiding the support arm (4), making it possible to guide it from its extreme releasing position in which it comes out of the catch toward its free position.

[0064] It is also important to note that, according to this embodiment, the supporting arm (4), when it is in the free position, is arranged in the same plane as the abutment (22) and is positioned next to the latter. In this way, during the injection process adapted to mass produce the circular ring (9) of the extraction device (1), the mold used is a simple mold, and is less expensive than in other slightly more complex embodiments which can require the use of so called slide molds.

[0065] According to a third embodiment in which the locking means (MV) are constituted by an abutment (22), for example, the extraction device (1) can have complementary immobilizing means adapted to enable the straw (2) to be immobilized within the can (3) when the supporting arm (4) is in the locked position (B). As a result, during the transportation and storage of the beverage cans (3), these immobilizing means reduce the biases on the supporting arm (4), and thus make it possible to avoid the ill-timed release thereof. Thus, as shown in FIGS. 12, 13, and 14, where the constituent elements of the extraction device (1) are designated by reference numerals that are similar to those used for equivalent elements in the previously described embodiments, the complementary immobilizing means of the straw (2) are constituted by a tube portion (30) open toward the bottom (BA) and located on the intermediate piece (9) in the axis of the straw (2) when the latter is in the locked position (B). As a result, the end (2a) of the straw (2), in this locked position (B), gets housed in the tube portion (30) so as to be immobilized therein. It is noted that the height (h1) of the end (2a) of the straw which is engaged in the tube portion (30) is lower than the height (h2) of the abutment along which the straw (2) and supporting arm (4) must travel to reach the releasing position, as shown in FIG. 14. Thus, during the actuation of the opening means (MO), the end (2a) of the straw exits the tube portion (3) before the arm reaches its releasing position.

[0066] According to this third embodiment, the supporting arm (4), or more specifically its articulation on the intermediate piece (9), has stress distributing means adapted to avoid having a zone where the stresses and deformations are too substantial, and which could lead to the rupture or damage of the articulation. Thus, as shown in FIGS. 12 and 13, the supporting arm (4) has sectional profiles, in the vicinity of its base, which have parallel lateral flat portions. This configuration makes it possible to stiffen the arm (4) when it works in flexion and to distribute the stresses in the entire articulation which includes two arm portions (31a, 31b) each having elastically deformable lateral flat portions arranged orthogonally, as shown in FIGS. 12 and 13, to constitute this type of elastically deformable gimbal.

[0067] The abutment system (22) adapted to retain the supporting arm (4) in its prestressing armed position is constituted by a hooking catch (220) formed of a horizontal support (220a) and a vertical edge (220b).

[0068] According to the various embodiments described, the extraction device is constituted by a piece in the form of an annular ring; however, according to other embodiments not shown, the device can be obtained in a plurality of pieces. Moreover, the constituent piece(s) of the extraction device could have a different form than the form of the annular ring, and can have a sector shape or the like, for example. Furthermore, according to the preferred embodiment, the fixing means of the annular piece are constituted by the peripheral edge adapted to be crimped between the cover and the peripheral wall of the can, said edge also constituting the sealing means of the device; however, it is understood that the fixing means could have a different configuration. Thus, the annular piece could, for example, not be provided with a peripheral edge, but could be fixed by wedging in the upper portion of the can which has a slightly truncated shape.

[0069] It is noted that the straw (2), constituted by two straw portions, namely, an external portion (20a) in which an internal portion (20b) slides, is advantageously retained by the retaining means (10) by its internal portion (20b), whereas the upper end of the external portion (20a) is in support on the lower edge of the tube portion (10) constituting said retaining means, as is shown in FIG. 14. In addition, the tube portion (10) is advantageously split to provide it with the adequate elasticity to ensure proper holding of the straw.

[0070] Furthermore, the extraction device (1) in the armed position with the straw (2) constitutes, during the assembly, a sub-assembly (100) adapted to come and clip itself in the cover (16) to be retained therein, in a manner so as to constitute an assembly (160) adapted to be introduced into the container (3) before crimping, as is shown in FIG. 15. The clipping ensuring the holding of the device (1) in the cover (16) before the positioning of the assembly (160)is obtained due to the slight flange (161) provided at the periphery of said cover. It is also noted that means are provided for indexing the relative angular position of the cover (16) with the device (1) of the invention making it possible to position the device (1) in a good angular position with respect to said cover (16), so that the straw, once it is released, projects and appears at the level of the hold made by the precut tongue (7).

[0071] Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents as well as their combinations.
