BACKGROUND

Field of the Invention

The present invention relates to beverages can. More specifically, this invention relates to a can with an advance closing system once it is opened.

Description of the Related Art

Metal beverage cans usually have a pull tab (working as a lever mechanism) to allow for the opening of the can along a pre-determined shallow groove. This design allows venting the excess pressure in the can when it is opened. As the tab is lifted, first a vent score is severed, allowing the gases in the can to be released, and then the aperture score is ruptured, which defines an aperture through which the contents of the beverage can may be dispensed. The groove has the shape of a non-closed loop, so that when pressure is applied by the lever to rip the metal along the groove, the metal tab that is ripped off remains attached to the top of the can, even when the lever is returned to its original position.

With existing cans, a permanent opening is formed by these manipulations, so that the contents of the can may be drunk, but on the other hand carbon dioxide may escape and spills may occur.

U.S. Pat. Nos. 4,784,283 and 5,810,189 disclose beverage cans that include a spring-loaded tab inside the can that is configured to reclose the drinking aperture after the can is opened for the first time. However, for a carbonated beverage can, pressure is built up in the can because of the gases. The pressure decreases as the amount of liquid in the can decreases, but the pressure can be quite high initially: depending on the temperature of the liquid, this pressure can be between 3 and 4 bar. Such a high pressure on a closing surface of e.g., 2.5 to 3.5 cm² results in a large force that needs to be counteracted when opening the can for drinking when the can still contains a large amount of beverage.

Patent application WO 2007/147542 A1 discloses a can end according to the preamble of claim 1. A closing device for beverage cans comprises an opening tab provided in a wall of the beverage can, an opening element for pressing the opening tab inwards, and a fixing device for detachably fixing the opening tab to said wall of the beverage.

Patent application US 2008/0314904, with inventor Perra, discloses a closing device for a food product container, more particularly a drink container, that includes a wall part provided with an opening and a shield member sealing the opening. The shield member is displaceable between a first, closed position sealing the opening in the wall part and a second, opened position leaving the opening at least partly open. The shield member is provided with a locking member securing the shield member in the first, closed position, and the shield member oriented in the first, closed position can be unlocked by displacing a locking member. The operations of unlocking and opening a (drinking) opening are separated such that both operations can be optimized independently of each other. The food product container can be used for carbonated drinks, such as sparkling water.

There are multiple solutions that have been presented in prior art. However, these solutions are limited and restricted to their conventional architecture, installation system and have considerable shortcomings which adversely affect the convenience with which they can be used. The prior systems have certain limitations including the opening latch system which is once opened cannot be closed again.

The current invention discusses a system for use with beverages can with advance closing system which can be rotated so that user can turn in one direction to close and the other to open to reseal the can for further usage retaining the same taste and fizziness of drink.

None of the previous inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Hence, the inventor of the present invention proposes to resolve and surmount existent technical difficulties to eliminate the aforementioned shortcomings of prior art.

SUMMARY

In light of the disadvantages of the prior art, the following summary is provided to facilitate an understanding of some of the innovative features unique to the present invention and is not intended to be a full description. A full appreciation of the various aspects of the invention can be gained by taking the entire specification, claims, drawings, and abstract as a whole.

The primary object of the invention is related to a reclosing system of cans which is an advancement in devices in similar field of use.

It is further the objective of the invention to provide a new reclosing system which is easy to use and easy to close.

It is also the objective of invention to provide an apparatus which is equally beneficial for beverages and food cans.

It is further the objective of invention to provide apparatus which sustains its effectiveness after repeated usage.

It is also the objective of the invention to provide apparatus which has a durable structure and is useful for every type of can and requires no major change in design of can.

This Summary is provided merely for purposes of summarizing some example embodiments, so as to provide a basic understanding of some aspects of the subject matter described herein. Accordingly, it will be appreciated that the above-described features are merely examples and should not be construed to narrow the scope or spirit of the subject matter described herein in any way. Other features, aspects, and advantages of the subject matter described herein will become apparent from the following Detailed Description, Figures, and Claims.

DETAILED DESCRIPTION

Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

The assembly provides an advance structure of closing cans once opened to retain their taste and fizziness. An advantage of embodiments of the advancement is that it is provided with means for easily reclosing after it is opened for the first time. Thus, spilling food or liquid is avoided. In some embodiments the reclosing is not only liquid tight but also gas tight. In case of a carbonated drink, the carbon dioxide will then not escape from the can as is the case with a traditional can, since the can according to the present invention is reclosed.

The invention as per its preferred embodiments includes, the container or can includes a can top, the can top comprising a cap top, arranged in connection to a pull tab configured to remove the cap top along a pre-defined groove or other form of mechanical weakness, to thereby create a drinking aperture. They can top preferably comprises a rotatable shut-off valve configured to close the drinking aperture during drinking and to seal the drinking opening when the can is not in use.

While a specific embodiment has been shown and described, many variations are possible. With time, additional features may be employed. The particular shape or configuration of the platform or the interior configuration may be changed to suit the system or equipment with which it is used.

Having described the invention in detail, those skilled in the art will appreciate that modifications may be made to the invention without departing from its spirit. Therefore, it is not intended that the scope of the invention be limited to the specific embodiment illustrated and described. Rather, it is intended that the scope of this invention be determined by the appended claims and their equivalents.

The Abstract of the Disclosure is provided to allow the reader to quickly ascertain the nature of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing Detailed Description, it can be seen that various features are grouped together in various embodiments for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus, the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separately claimed subject matter.
