Description
- The present application is a divisional of parent U.S. application Ser. No. 10/069,614, filed Sep. 10, 2002, which is a National Stage Application of International Application No. PCT/IB00/01205, filed Aug. 30, 2000. Further, the present application claims priority under 35 U.S.C. § 119 of French Patent Application No. 99/11190 filed on Aug. 31, 1999.
- 1. Field of the Invention
- The present invention relates to a method of positioning in a container, such as a can, a device for automatically extracting a straw, and its associated device.
- 2. Discussion of Background Information
- Numerous types of 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.
- 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 shape of the container itself.
- In the particular case of metallic cans or 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 containers, which are ingested by the consumer when he places his lips on the container.
- 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.
- Therefore, a device for automatically extracting a straw has been developed to equip the cylindrical metallic cans of the type having a container closed by a crimped cover, which includes opening means constituted of a push ring adapted to displace a precut tongue inward of the can.
- Such an extraction device is described, for example, in the published French Patent No. 2 772 731, and includes a straw-supporting member constituted by an elastically deformable retention arm, one of the ends of which is connected to a peripheral ring, and the other of which includes means for retaining the straw. The peripheral ring is adapted to be sandwiched between the cover and more particularly its crimping groove and the upper peripheral rim of the container, whereas the retention arm is tensioned before being displaceably positioned and placed in support on a fixed abutment affixed to the peripheral ring. Such a method, which consists of deforming the arm before it is positioned beneath the cover requires a complex, expensive, and unreliable assembly line, particularly in view of the imposed high filling rates.
- The present invention therefore proposes to resolve these disadvantages by proposing a device without fixed abutment for the deformed straw retention arm, and its embodiment method.
- According to one aspect of the invention, there is provided a method of positioning, in a can including a container closed by a cover, a device for automatically extracting a straw. The device is of the type which includes a straw-supporting member constituted by an elastically deformable retention arm adapted to be tensioned by elastic deformation. The arm includes a retention tube for the straw. The method is characterized in that it provides for tensioning the arm by the direct or indirect effect of the cover during the coupling of the cover to the device.
- The method includes the following preliminary steps:
- a. fixing or securing the straw to the retention arm to form an intermediate subassembly, namely, the straw-extraction device subassembly; and
- b. coupling of the intermediate subassembly to the cover to form a closure subassembly; the method may also include the following complementary steps:
- c. filling up the container with the desired beverage;
- d. positioning the closure subassembly in the container;
- e. crimping the cover on the container.
- According to another aspect of the invention, the method provides for tensioning the retention arm by the action of the cover on a projection affixed to the retention arm, or on the straw retained by the arm.
- The invention also relates to a device for extracting a straw adapted to implement the method, which comprises a straw-supporting member constituted by an elastically deformable retention arm, one of the ends of which is connected to a peripheral ring or annular ring, whereas the free end of the arm includes a mechanism for retaining the straw.
- According to another aspect of the invention, the mechanism for retaining the straw includes a retaining tube portion.
- According to another aspect of the invention, the device is obtained in a single piece made of injected plastic material, whereas the annular ring includes a succession of deformable lips that are peripherally sandwiched, during the crimping of the can, between the cover and more particularly its crimping groove and the upper peripheral rim of the opening of the container.

- The causing may comprise one of deflecting the straw supporting member and tensioning the straw supporting member. The straw supporting member may move from the first position to the second position when, directly or indirectly, the cover is coupled to the device. The straw supporting member may comprise an elastically deformable retention arm that is adapted to be tensioned by elastic deformation. The elastically deformable retention arm may include a retention mechanism adapted to retain the straw. The method may further comprise fixing the straw to the straw-supporting member to thereby form an intermediate subassembly and coupling of the intermediate subassembly to the cover to form a closure subassembly. The fixing may comprise fixing the straw to an elastically deformable retention arm of the straw-supporting member to thereby form an intermediate subassembly.
- The method may further comprise filling a container with a desired beverage, positioning the closure subassembly in the container, and securing the cover on the container. The securing may comprise crimping the cover on the container.
- The straw-supporting member may comprise an elastically deformable retention arm having a projection and the method may further comprise engaging the cover with the projection, whereby the elastically deformable retention arm is deflected or tensioned. The straw-supporting member may comprise an elastically deformable retention arm and the method may further comprise engaging the cover with the straw, whereby the elastically deformable retention arm is deflected or tensioned.
- The invention also provides a device for extracting a straw comprising a straw-supporting member having an elastically deformable retention arm which comprises a free end and at least another end. A body comprises one of a peripheral portion and an annular portion. The at least another end of the elastically deformable retention arm is connected to the body.

FIG. 25 is a perspective bottom view of an alternative of the second embodiment of the device. - The invention relates to a method of positioning a straw automatic extraction device, generally designated by the
reference numeral 1. The device is adapted to automatically extract, when it is being opened, astraw 2 arranged within acontainer 3. Theextraction device 1 is advantageously described in the particular case of metallic cylindrical cans whose opening systems are constituted in a known fashion by apush ring 4 and aprecut tongue 5, also called a cap. Thecap 5 can pivot inwardly of thecontainer 3 under the effect of the ring to free the orifice 6 of the opening system, as shown inFIGS. 1 and 2 . It is understood that theautomatic extraction device 1 according to the invention could be modified to be adapted to other types of containers, or to other types of opening systems without leaving the scope of protection of the invention. - The
extraction device 1 is adapted to be used with the method of the invention and comprises a straw-supportingmember 7 constituted by an elasticallydeformable retention arm 8, one of the ends of which is connected to a peripheral ring orannular ring 9. Furthermore, the free end of thearm 8 includes a mechanism for retaining thestraw 2, which includes a retainingtube portion 10 that is advantageously open to provide it with enough elasticity to ensure pinching of thestraw 2. - The
extraction device 1 is advantageously obtained or made in a single piece of injected plastic material. Theannular ring 9 includes a succession ofdeformable lips 15 that are peripherally sandwiched during the crimping of thecan 3 between thecover 14, and more particularly its crimping groove and the upper peripheral rim of the opening of thecontainer 3, as seen inFIGS. 6 a and 11 a. - In a first embodiment of the
extraction device 1 shown inFIGS. 3-7 , themechanism 10 for retaining the straw is extended upwardly by aprojection 11 for deforming the arm that extends upwardly. - The
projection 11 is constituted by a cylindrical wall portion whoseupper end 12 is adapted to come into abutment on thelower wall 13 of thecover 14 during its coupling to thedevice 1, as shown inFIGS. 6 and 16 , and, of course, during the crimping of thecover 14, thus causing the downward deformation along direction F of thearm 8, as shown inFIG. 6 andFIG. 16 . - In a second embodiment of the
extraction device 1 shown inFIGS. 8-12 , theretention arm 8, and more particularly itsretaining mechanism 1, does not include a deforming projection. According to this alternative embodiment, the deforming of the arm occurs by the direct effect of the cover on the straw. Furthermore, thearm 8 includes anactuating arm 18 that is adapted to be actuated and displaced by the cap ortongue 5 during the opening of the can. In this alternative embodiment, the elastic linkage of theretention arm 8 with theperipheral ring 9 is obtained by the succession of two elastically deformable zones: afirst deformation zone 16 for enabling theretention arm 8 to displace in horizontal pivoting about a vertical pivoting axis XX′, and asecond deformation zone 17, distinct from thefirst deformation zone 16, for enabling thearm 8 to displace in vertical pivoting about a horizontal pivoting axis YY′. It is noted that thesecond deformation zone 17 is a deformable flat section, but it could have any other shape, and may, in particular, have a arrangement similar to that which is shown inFIG. 25 . - In the two embodiments of the
extraction device 1, it is noted that in the non-stress rest position, as shown inFIGS. 3, 4 , 5, 7, 8, 9, 10, 12, 13, 14, 15, 19, 20, and 21, theretention arm 8 extends from the peripheral ring inwardly, substantially horizontally, at least in a plane substantially parallel to the general plane H of thering 9. - Conversely, in the prestress active position, as shown in
FIGS. 6, 11 , 16, 17, 22, 23, and 24, the retainingarm 8 forms, together with the general plane H of theperipheral ring 9, a sharp angle A comprised between 20 and 60 degrees and, for example, 40 degrees. - According to one method of positioning the
extraction device 1, theretention arm 8 is elastically biased downwardly along direction F, such that, during opening, this elasticity is restored in order to have thestraw 2 move or be extracted out of the opening 6, as shown inFIGS. 6, 11 , 16 and 22. - The stressing of the arm is done at the time the
cover 14 is coupled to thedevice 1, as shown inFIGS. 6, 11 , 16, 17, 22, and 23 by the direct or indirect effect of thecover 14 on theretention arm 8. - With the first embodiment of the
device 1, thelower wall 13 of thecover 14 biases theretention arm 8 into a downward elastic prestress by its direct effect on theend 12 of theprojection 11 for deforming the arm. - With the second embodiment of the
device 1, thelower wall 13 of thecover 14 biases theretention arm 8 into a downward elastic prestress by its direct effect on theend 21 of thestraw 2 retained by thetubular retaining portion 10. - It is understood that with the first embodiment of the
extraction device 1, during the opening of the can, the cap ortongue 5 releases theretention arm 8 of thestraw 2 which, having been elastically prestressed, returns to its inactive position to drive with it the end of thestraw 2 which then projects out of the opening 6. - With the second embodiment of the
extraction device 2, the end of theactuation arm 18 is arranged in the trajectory of the cap ortongue 5. Thus, during opening of the can, the cap ortongue 5 acts on or engages theactuation arm 18 to pivot the assembly which it forms with theretention arm 8 about the axis XX′, and thus to place the end of thestraw 2 in the zone of the opening 6. In this way, thestraw 2 is allowed to project immediately through this opening 6 by the release of the prestress. - According to one embodiment, the invention provides for a method that includes the following preliminary steps:
- a. Securing the
straw 2 to theretention arm 8 by introducing thestraw 2 into theretention tube 10 to form anintermediate subassembly 30, namely, thestraw 2 and theextraction device 1 subassembly. - During this operation, it should be ensured that the
straw 2 extends upwardly by an adequate height L comprised between 10 and 25 millimeters (seeFIGS. 13, 14 , andFIGS. 19 and 20 ). - b. Coupling the
intermediate subassembly 30 to thecover 14 to form aclosure subassembly 41. - In this step, the
subassembly 30 is engaged beneath thecover 14 and clipped to the latter by cooperation of the succession oflips 15 with theperipheral groove 31 of the cover (seeFIGS. 15, 16 , andFIGS. 21 and 22 ). Of course, the positioning of the device with its straw with the cover is done with a relative predetermined angular orientation. During the clipping of thesubassembly 30 to thecover 14, thelower wall 13 of the latter, directly or indirectly, forces theretention arm 8 downwardly so as to place it in the prestress position, as shown inFIGS. 6, 16 , andFIGS. 11 and 22 . - During the bottling itself, the following complementary successive steps are undertaken:
- c. filling the
container 3 with the desired beverage; - d. positioning the
closure subassembly 41 in thecontainer 3, as shown inFIGS. 17, 18 , andFIGS. 23 and 24 ; and - e. crimping the
cover 14 on thecontainer 3. - In the alternative embodiment shown in
FIG. 25 , thesecond deformation zone 17 is a hollow open section, especially omega-shaped so as to provide the zone with appropriate elasticity. - The
straw 2 used is advantageously a telescopic, flexed straw, i.e., one which includes a deformation accordion. - It is noted that the device can include a guiding
ramp 90 for the end of thestraw 2, as seen inFIGS. 9, 10 , and 25. - Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all of the technical equivalents, as well as their combinations.
