The invention relates generally to the field of can openers. More specifically, the invention relates to devices that can aid in opening cans having pull tab openers.
Devices for opening cans having pull tabs are set forth herein. According to one embodiment, a device for opening and closing a can with a pull tab includes a forward portion and a rear portion. The forward portion has a top wall and a bottom wall. A cavity is formed between the top and bottom walls. The cavity is configured to receive the pull tab of the can. The rear portion extends from the forward portion. The rear portion has a proximal sidewall and a distal sidewall. The rear portion has a curved groove adjacent the distal sidewall. The curved groove is configured to snap onto a lip of the can. A recessed portion extends from the distal wall of the rear portion.
According to another embodiment, a device for opening and closing a can with a pull tab device includes a top portion and a bottom portion. The can has a top side with a tear panel for providing access to the contents of the can. The can top side has a pull tab for rupturing the tear panel. The pull tab has front and back ends and is attached to the can top side by a rivet. The rivet is closer to the back end of the pull tab than the front end. The pull tab back end is initially adjacent the tear panel, such that when the pull tab front end is lifted away from the can top side, the pull tab back end pushes the tear panel into the can. A hole is formed by the rupturing of the tear panel, and the contents of the can may be accessed through this hole. The pull tab is rotatable around the rivet, allowing the pull tab to rotate at least 180 degrees and the pull tab front end to selectively be upwardly adjacent the hole. The claimed device may be used to open and close the can. A cavity is formed between the top and bottom portions of the opening/closing device. The bottom portion has an indentation that is complimentary to the rivet. The cavity has a front side, a back side, a first lateral side, and a second lateral side. The opening/closing device includes an intermediate wall having a J-shaped cross-section. The intermediate wall has a proximal side and a distal side. The proximal side closes the first lateral side and the back side of the cavity. The proximal side partially closes the second lateral side of the cavity. The cavity is configured to receive the pull tab front end. The intermediate wall has a curved groove adjacent the distal side. The curved groove is configured to snap onto a lip of the can. A recessed portion extends from the distal side of the intermediate wall. The bottom portion is configured to lift the pull tab front end when the pull tab front end is received in the cavity and the recessed portion is raised to open the can. The bottom portion and the intermediate wall are collectively configured to cover the can hole when the pull tab front end is received in the cavity and the pull tab front end of the opened can is rotated to be upwardly adjacent the hole.
According to still another embodiment, a device for opening a can with a pull tab includes a top portion and a bottom portion. The can has a top side with a tear panel rupturable by the pull tab for providing access to the contents of the can. The pull tab has front and back ends and is attached to the can top side by a rivet. The rivet is closer to the back end of the pull tab than the front end. The pull tab back end is adjacent the tear panel, such that when the pull tab front end is lifted, the pull tab back end pushes the tear panel into the can, opening the can and forming a hole. A user may access a beverage within the can from the hole. A cavity is formed between the top and bottom portions of the opening device. The bottom portion has an indentation that is complimentary to the rivet. The opening device includes an intermediate wall with a curved groove configured to snap onto a lip of the can. A recessed portion is coupled to the intermediate wall. The cavity is configured to receive the pull tab front end, and the bottom portion is configured to lift the pull tab front end when the pull tab front end is received in the cavity and the recessed portion is raised. The recessed portion is lower than the top portion to prevent the user from hitting the user's nose with the device when consuming the beverage within the can while the curved groove is snapped onto the can lip.
Illustrative embodiments of the present invention are described in detail below with reference to the attached drawing figures, wherein:
Devices and methods for opening and closing a can having a pull tab are set forth herein.
The forward portion 300, the rear portion 310, and the recessed portion 330 may be of a unitary (i.e., one piece) construction. Or, different parts of the device 10 may be made out of different materials; for example, the forward and rear portions 300, 310 may be made out of plastic, while the recessed portion 330 may be made out of wood. Other appropriate materials may include rubber, metal, or stone, for example. It may be desirable for the device 10 to be dishwasher safe, recyclable, or have other properties that may affect material selection.
An intermediate wall 200 separates the top portion 100 and the bottom portion 110. As shown in
As shown in
The intermediate wall 200 has a curved groove 150 that is adjacent the intermediate wall distal side 220 and the rear portion distal sidewall 314. The curved groove 150 is configured so that it can snap onto a lip 530 of a can 500 (
As shown in
The recessed portion 330 has an opening 332 (
The forward portion 300, the recessed portion 330, the top portion 100, and the bottom portion 110 shown in
The can 500 with which the device 10 is employed is known in the art and is shown in
Initially, as shown in
The can lip 530 surrounds the can top side 502 and is typically formed by a bonding process. The can lip 530 may extend higher than the top side 502 and a can lip bottom side 530B may protrude from a can side 500S.
The pull tab 510 is rotatable around the rivet 520, and the pull tab 510 may be rotated and positioned at different places on the can top end 502. For example, the pull tab 510 may be rotated about 180 degrees from its initial position such that the pull tab front end 512 is atop the can hole 550, while the pull tab back end 514 faces away from the hole 550. Using the pull tab 510 to rupture the tear panel 504 may not inhibit the ability of the pull tab 510 to rotate around the rivet 520.
Attention is now directed to the use of the device 10 with the can 500, as shown in
Alternatively, to slide the device 10 onto the pull tab 510, the user may place the device 10 such that the cavity front side 122 is adjacent the pull tab front end 512, and the bottom portion 110 is adjacent the can top side 502. The user may then push the device 10 and slide the pull tab front end 512 into the cavity front side 122, until either the indentation back side 130B comes into contact with the can rivet 520, or the pull tab front end 512 comes into contact with the cavity back side 124. It may be easier to slide the device 10 onto the pull tab 510 from the cavity second lateral side 128E than from the cavity front side 122, because there is more space between the can lip 530 and the pull tab side 516, than the can lip 530 and the pull tab front end 512.
After sliding the device 10 onto the pull tab 510, the user may then lift the recessed portion 330. Lifting of the recessed portion 330 may cause the bottom portion 110 to move away from the can top side 502 and lift the pull tab front end 512 inside the cavity 120. Lifting of the pull tab front end 512 may cause the pull tab back end 514 to move downward into the tear panel 504, eventually rupturing the tear panel 504. The tear panel 504 may move into the hole 550 that is formed by the rupturing of the tear panel 504.
Lifting of the recessed portion 330 to rupture the tear panel 504 instead of lifting the pull tab front end 512 may have several advantages. Ordinarily, for example, a user has to first pry the user's index finger, another finger, or a fingernail under the pull tab front end 512 before being able to lift the front end 512. This may be difficult, especially if the pull tab front end 512 is very close to the can top 502. Also, if the user does not have long fingernails or has big fingers, it may be difficult for the user to slide a fingernail or finger under the pull tab front end 512. The device cavity 120 can easily be slid towards the pull tab 510, and the solid recessed portion 330, generally being spaced apart from the top end 502, provides a convenient and easily accessible alternative to the pull tab front end 512. The forward portion bottom wall 300B may be beveled to aid in sliding the pull tab 510 into the device cavity 120. Moreover, the greater length of the device 10 as compared to the pull tab 510 may provide better leverage to open the can 500, such that less force may need to be applied to rupture the tear panel 504. The device 10, therefore, may be especially helpful for people with joint pain in their fingers (e.g., arthritis).
After opening the can 500, the user may snap the curved groove 150 on the can lip 530, as shown in
As mentioned above, the pull tab 510 is rotatable around the rivet 520. The device 10 can be rotated along with the pull tab 510 around the rivet 520, notwithstanding the curved groove 150 being snapped onto the can lip 530. Once the can 500 is opened and the curved groove 150 is snapped onto the can lip 530, the device 10 can be rotated about 180 degrees along with pull tab 510 such that the pull tab front end 512 is upwardly adjacent the can hole 550 and the pull tab back end 514 faces away from the can hole 550. Said differently, the device 10 with pull tab 510 can be rotated such that the cavity front end 122 faces away from the hole 550, while the bottom portion 110 is directly atop the can hole 550. As such, the device 10 can be rotated selectively such that the bottom portion 110 and/or the intermediate wall 200 collectively cover the can hole 550 completely or nearly so.
The ability to cover the can hole 550 of an open can 500 may have various advantages. For example, if the can 500 is accidentally tipped over, the device 10 may eliminate or at least limit the contents of the can 500 from spilling out of the can 500. Or, when open cans 500 are placed in cup holders of cars, contents of the uncovered cans 500 often spill out when the car suddenly brakes or goes over a bump in the road. The device 10 may allow the user to eliminate or limit this spillage. Moreover, covering of the can hole 550 may prevent debris, insects, or other unintended objects from entering the can 500. Nevertheless, the can hole 550 may only be partially covered with the bottom portion 110, to provide different sized vents and openings in the can hole 550 for consuming the beverage.
The device 10 may also be used for advertisement; for example, the top portion 100 may include indicia relating to a sponsor. Since the device 10 may be reusable, any indicia relating to a sponsor may potentially be seen repeatedly for years, both by the user and others. Generally, the top side 502 of a can 500 is devoid of any logos or sponsor information. Therefore, the device 10 may provide an eye catching way for sponsors to display advertisements at a can top side 502. Or, the top portion 100 may include a quote or a message, and function akin to a bumper sticker on a car.
Often, at parties or other gatherings, several users may drink the same type of beverage from the same kind of can 500, and their cans 500 may get mixed up, such that it is difficult to determine which can 500 belongs to which user. All or part of the device 10 may be colored, and different devices 10 may be of different colors or have other identifying characteristics, so that users may identify their respective can 500 from a plurality of similar cans 500.
The device 10 disclosed above is designed primarily for use by right-handed users, however, it will be apparent to those skilled in the art that the device 10 may be easily modified for use by left-handed users. To achieve this modification, the intermediate wall proximal side 210 may fully close the cavity second lateral side 128, and instead of completely closing the cavity first lateral side 126, the intermediate wall proximal side 210 may leave the cavity first lateral side 126 partially exposed. In effect, the cavity first lateral side 126 and the cavity second lateral side 128 may be switched.
Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention. Embodiments of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the claims. Not all steps listed in the various figures need be carried out in the specific order described.
