Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to beverage cans, and more particularly, to a beverage can with a sucking means, which is designed such that a straw is automatically projected from the inside to the outside of the can when removing a one-touch opening portion defined on the top surface of the can, thus allowing a user to easily suck beverage through the projected straw, therefore being more sanitary and convenient to the user while drinking beverage contained in the can.

[0003] 2. Description of the Prior Art

[0004] Generally, various kinds of drinking water, beer, herbal medicine, and health drinks (hereinafter referred to as “beverage”) are packed in portable cans through a vacuum packaging method, thus allowing people to easily drink beverage from the cans.

[0005] A conventional beverage can is made of metal, such as aluminum, and contains beverage therein. The conventional beverage can is advantageous in that it is easy to market or handle, in addition to being relatively sanitary. The beverage can is designed such that its opening portion is removed in a one-touch method, so the opening portion is easily removed without additional tools, thus allowing people to conveniently drink beverage contained in the can. Due to such numerous advantages, use of the beverage cans has steadily grown.

[0006] Such a conventional beverage can will be described with reference to FIG. 1.

[0007] As shown in the drawing, a beverage can 1 comprises a cylindrical body 2 with an opening portion 4. The opening portion 4 is integrally formed at a position on the top surface 3 of the body 2, and is defined by a tearing line 4a. A pull-tab 6 is exteriorly fixed to the opening portion 4 by a rivet 5.

[0008] The conventional beverage can 1 is designed such that the opening portion 4 is removed inwardly or outwardly with respect to the body 2 along the tearing line 4a to form an outlet port, when levering the pull-tab 6 upward. At this time, a user can drink beverage contained in the can through the outlet port.

[0009] However, since the outlet port is formed on the same plane with the top surface 3 of the body 2, contents in the can 1 may be splashed as soon as the opening portion 4 is removed, thus getting a user's dress wet or soiling an area around the user. Further, the user's lips must be in contact with a portion around the outlet port in order to drink beverage from the can. Thus, in the case where the portion around the outlet port is soiled, it may be unsanitary. Above all, in the case where a female user wearing lipstick drinks beverage from the can, the lipstick may be removed. Further, adults' assistance is required for children to drink beverage from the can without spilling the beverage.

[0010] In order to solve the problems experienced in the conventional beverage cans, as shown in FIGS. 2 and 3, a beverage can was proposed by this inventor and registered as Korean U.M. No. 191393.

[0011] As shown in the drawings, the beverage can 10 proposed by this inventor is designed such that an opening portion 12 is removed along a tearing line 12a when levering a pull-tab 11, and includes a bracket 13 and a straw 14. The bracket 13 having a predetermined height is interiorly mounted at its top end to the opening portion 12, and has a port at its bottom wall 13a. The collapsible straw 14 is set on the bottom wall 13a of the bracket 13 as it is withdrawn. Thus, in the case of removing the opening portion 12, the withdrawn straw 14 is elastically and outwardly projected from the interior of the can 10.

[0012] The cylindrical bracket 13 is slightly larger than the opening portion 12 in its diameter. A flange 14a is provided at the lower end of the straw 14 and is fixed to the bottom wall 13a of the bracket 13 using an adhesive.

[0013] When a user removes the opening portion 12 in order to drink beverage from the beverage can 10, the straw 14 is elastically and outwardly projected from the can 10, so that the user can drink beverage through the straw 14.

[0014] Thus, contents in the can are prevented from being splashed when removing the opening portion 12, and user's lips do not come into contact with a portion around the opening portion 12, thus allowing a user to neatly and sanitarily drink beverage from the can 10. Especially, even when a female user wearing lipstick drinks beverage from the can 10, her lips are not in contact with a portion around the opening portion 12, so she does not worry about the removal of her lipstick.

[0015] Further, since the straw 14 outwardly projected from the can 10 completely enters a user's mouth, it is convenient to drink beverage from the can 10, and besides, children can neatly drink beverage from such cans 10 without the assistance of adults.

[0016] However, the above-mentioned beverage can 10 has the following problems.

[0017] The top end of the straw 14 set in the can 10 is elastically in contact with the bottom surface of the opening portion 12. However, a small amount of beverage may flow into and be collected in the bracket 13 through the top end of the straw 14 by a shock generated during marketing or handling the beverage can 10. At this time, when removing the opening portion 12 to drink beverage from the can 10, the beverage flows out from the bracket 13, thus soiling the users mouth region.

[0018] As shown in FIG. 3, the beverage can 10 is naturally inclined when drinking the beverage from the can 10. At this time, a user cannot drink beverage remaining in the bracket 13, because the straw 14 does not reach the beverage collected in the bracket 13.

[0019] Further, the flange 14a made of synthetic resin is provided at the lower end of the straw 14, and is fixed, using an adhesive, to the bottom wall 13a of the bracket 13 made of metal. However, the adhesive force between the flange 14a and the bottom wall 13a is not strong, so that the flange 14a may be separated from the bottom wall 13a during marketing and/or handling the beverage can 10. Furthermore, it is difficult to automate the process of adhering the flange 14a to the bottom wall 13a.

SUMMARY OF THE INVENTION

DESCRIPTION OF PREFERRED EMBODIMENTS

[0042] Reference should now be made to the drawings, in which the same reference numerals are used throughout the different drawings to designate the same or similar components.

[0043] As shown in FIGS. 4 to 8, according to the primary embodiment of this invention, a beverage can 20 is provided at the top surface 22 of its body 21 with an opening portion 23, and is designed such that a straw 24 is elastically projected from the inside to the outside of the can 20 by itself, when the opening portion 23 is removed.

[0044] The opening portion 23 is easily removed along a tearing line which is formed on the top surface 22 of the body 21, and a pull-tab 26 is fixed to the opening portion 23 by a rivet 27, in the same manner as a conventional beverage can.

[0045] According to the primary embodiment of this invention, the beverage can 20 has an openable cover 24a on the top end of the straw 24. The straw 24 is provided on its lower portion with a holding part 24b. The holding part 24b has an outer diameter larger than the diameter of a port 25b of a bracket 25 while having an inner diameter smaller than the diameter of the port 25b. A circular groove 24ba is formed around the outer surface of the side wall of the holding part 24b. Further, the lower end of the holding part 24b is tapered to have an outer diameter smaller than the diameter of the port 25b of the bracket 25 such that the circular groove 24ba of the holding part 24b easily engages into the port 25b of the bracket's bottom wall 25a.

[0046] The straw 24 is made of synthetic resin having a predetermined elasticity, and has a bellows structure which is elastically contracted when collapsed.

[0047] The cover 24a seated on the top of the straw 24 may have a variety of shapes. For example, as shown in FIG. 6a and 6b, the cover 24a may consist of an insert part 24aa and a flange 24ab. The insert part 24aa is downwardly projected to be inserted into the upper portion of the straw 24. The flange 24ab extends outwardly from the top of the insert part 24aa.

[0048] In addition, as shown in FIGS. 7a and 7b, a cover 24a′ may be formed to close the upper portion of the straw 24, and a notch 24a′a may be formed at an upper portion of the straw 24. In this case, the cover 24a′ must be pulled to be separated from the straw 24 so as to drink beverage contained in the can 20.

[0049] The engagement of the straw 24 into the port 25b of the bracket 25 is accomplished by pushing the holding part 24b of the straw 24 into the port 25b while the cans are being produced. At this time, the holding part 24b having a predetermined elasticity is contracted while the circular groove 24ba engages with the bottom wall 25a around the port 25b. Thus, the process of setting the straw 24 at the port 25b of the bracket 25 can be easily and automatically performed.

[0050] Since the straw 24 itself has appropriate elasticity, it can provide an airtight seal at the bottom wall 25a of the bracket 25. However, if necessary, rubber packing can be fitted along the edge of the port 25b formed on the bottom wall 25a to enhance the airtight sealing effect between the straw 24 and the bottom wall 25a of the bracket 25.

[0051] In order to allow a user to drink all of the beverage from the can 20, as shown in FIGS. 4 and 5, the straw 24 is set at the port 25b of the bracket 25. In this case, the outer diameter of the bracket 25 is the same diameter as the inner diameter of the body 21.

[0052] Since the outer diameter of the bottom wall 25a of the bracket 25 is the same as the inner diameter of the body 21, the bottom wall 25a substantially forms a ceiling defining the inside space of the body 21.

[0053] Preferably, both the port 25b provided on the bottom wall 25a of the bracket 25 and the opening portion 23 of the top surface 22 are formed at vertically aligned positions offset from the center of the top surface 22, thus allowing a user to drink all of the beverage from the can 20, as shown in FIG. 8.

[0054] Further, in order to allow a user to drink all of the beverage from the can 20, as shown in FIGS. 5 and 9, an extending part 24c may integrally extend from the lower end of the holding part 24b to a position adjacent to the bottom of the body 21. In this case, a user must suck almost all of the beverage contained in the can 20 through the straw 24.

[0055] In a beverage can 30 according to a second embodiment of this invention, as shown in FIGS. 10 to 13, an opening portion 33 is formed on the central portion of the top surface 32 of a body 31, and a port 35b of a bracket 35 is formed on the central portion of a bottom wall 35a of the bracket 35 which is positioned under the opening portion 33. The bottom wall 35a of the bracket 35 is curved in such a way as to be reduced in height from the port 35b toward the side wall of the body 31. A straw 34 is set at the port 35b formed on the central portion of the bottom wall 35a of the bracket 35.

[0056] According to the second embodiment, the beverage can 30 is designed such that the opening portion 33, a pull-tab 36, and a rivet 37 are formed on the central portion of the top surface 32 of the body 31, so that the top surface 32, the bracket 35 and the body 31 are assembled together without hindrance, resulting in a more efficient manufacturing process.

[0057] As shown in FIGS. 11a, 11b, 12a and 12b, a ring 34c is fitted over the side wall of the straw 34, and is coupled to the cover 34a by a coupling wire 34d.

[0058] In FIGS. 11a and 11b, the straw 34 consists of an insert part 34aa and a flange 34ab. The insert part 34aa is inserted into the upper portion of the straw 34. The flange 34ab extends outwardly from the top of the insert part 34aa. In FIGS. 12a and 12b, a cover 34a′ is formed to close the top end of the straw 34, and a notch 34a′a is formed at the upper portion of the straw 34. In this case, when one desires to drink beverage contained in the can 30, the cover 34a′ must be pulled to be separated from the straw 34.

[0059] As shown in FIGS. 11a, 11b, 12a, and 12b, the straw 34 is provided on its lower portion with a holding part 34b. The holding part 34b has an outer diameter larger than the diameter of the port 35b of the bracket 35 while having an inner diameter smaller than the diameter of the port 35b. A circular groove 34ba is formed on the side wall of the holding part 34b. Further, the lower end of the holding part 34b is formed to have an outer diameter smaller than the diameter of the port 35b of the bracket 35 such that the circular groove 34ba of the holding part 34b easily engages with the bottom wall 35a at the edge of the port 35b.

[0060] The straw 34 according to the second embodiment is longer in length, in comparison with the primary embodiment.

[0061] When one desires to drink beverage contained in the can 30, the opening portion 33 must be removed by pulling the pull-tab 36 fixed to the opening portion 33 by means of the rivet 37. At this time, the straw 34 is elastically and outwardly projected from the can 30, and then the cover 34a or 34a′is removed in order to drink beverage from the can 30. In the case where the can 30 is almost empty, as shown in FIG. 13, the can 30 is rotated upward at an angle of 180° to be perpendicular to a user's mouth. In this case, the straw 34 can be naturally bent, so people can drink beverage from the can 30 without any difficulty. Further, the bottom wall 35a of the bracket 35 is curved as described above, so the remaining beverage is collected at the central portion of the bottom wall 35a when the can is turned upside down, thus allowing people to drink almost all of the beverage from the can 30.

[0062] Since the cover 34a or 34a′ of the straw 34 is connected to the body 31 by the coupling wire 34d, the cover 34a or 34a′ is disposed of together with the beverage can 30 after drinking all of the beverage from the can 30, thus reducing environmental contamination, in comparison with the case where the cover 34a or 34a′ is separately thrown away. In addition, when a user drinks a little beverage from the can 30, the remaining beverage can be preserved by closing the cover 34a or 34a′.

[0063] As described above, the present invention provides a beverage can, which prevents contents from flowing out when removing a one-touch opening portion, and which is designed such that the contents do not flow into a bracket during marketing and handling of the can, thus allowing a user to cleanly drink without soiling the region around a users lips, and which is designed such that the user's lips are not in contact with a portion around the opening portion, thus making it sanitary and convenient to drink beverage contained in the can, and which allows a user to drink almost all of the beverage from the can.

[0064] Further, the present invention provides a beverage can, which is designed to allow for easy positioning of a straw at a port of a bracket, thus automating the process of mounting the straw in the can.

[0065] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
