JP2002096859A - Mug type can container for carbonated beverage - Google Patents

Abstract

PROBLEM TO BE SOLVED: To endure against an inner pressure produced by carbonic acid gas which is a feature of carbonated beverage, enable an upper lid to be easily and fully opened, cause a handle utilizing a tab to be mounted and realize a feeling of beer mug by a can container. SOLUTION: An upper lid is comprised of a spherical central part (2) and a periphery (3) in parallel with a can body (6). A cutting scratch line (4) is formed at the periphery (3) in parallel with the can at a position where a shearing force provided by an inner pressure and a bending stress become minimum. The cutting scratch line is not fully formed at an entire circumference and the portion (5) having no cutting scratch line is left at the can body to keep the upper lid connected to the can body when the lid is opened. A length of a tab is set to be approximately equal to a diameter of the upper lid, an L- shaped and bent extremity end (7) is formed into such a shape as one in which it is engaged with a can bottom part, resulting in that a shape of the handle using the tab (1) connecting the upper surface of the lid with the can bottom part under utilization of a spring characteristic of metal material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is characterized in that a carbonated beverage can has an opening area of an upper lid diameter and a tab (1), which is a part used for opening the can, has a function of contacting a handle of a beer mug. It is a can for carbonated beverages.

[0002]

2. Description of the Related Art Conventional canned containers of foamed and carbonated beverages such as canned beer have small openings due to the need to withstand the internal pressure caused by carbon dioxide gas, so that the beverage can be sucked through holes and the original taste of the beverage is impaired. ing.

[0003]

A feeling of drinking with a mug by using a tab (1) as a handle to withstand internal pressure due to carbon dioxide, which is a characteristic of carbonated beverages, to easily open fully with an opening area of the diameter of the upper lid. Is provided.

[0004]

The upper lid is composed of a central portion (2) of a spherical surface and a peripheral portion (3) parallel to the can body. The cutout score line (4) has a minimum cutting stress and bending stress due to internal pressure. At the peripheral portion (4) parallel to the can body. The marking line (4) is not put in the whole circumference, and the upper lid is connected to the can body (5) when opened by leaving a part that cannot be put. The tab (1) has a length substantially equal to the diameter of the upper surface of the can, the tip (5) bent into an L shape is hooked to the bottom of the can, and a handle connecting the upper surface of the can and the bottom of the can is formed by metal spring property. .

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The tab (1) can be grasped by enlarging the tab (1), and the point where the second joint part of the index finger and the middle finger contacts the lid is used as a fulcrum and a light force by leverage action. Can be used as a beer mug by having a handle-shaped portion (1) formed by opening the tab with the area of its diameter and directly hanging the tab on the bottom of the can. After use, the container is folded and stored in a can with the can body, top lid, and tab connected, and the same treatment as conventional cans is performed as resource waste.

[0006]

EFFECTS OF THE INVENTION A sparkling beverage, such as canned beer, had its original flavor impaired because it was drunk from a small opening of the can. By fully opening the jar, the scent, flavor, and feel of the foam you drink with the mug can be obtained. The cut surface of the lid is located on the inside of the can where the lips do not touch, ensuring safety, and it can be used as a cup for outdoor play such as camping.
The can body, lid, and tag remain connected and parts do not scatter finely after use.

Claims (2)

[Claims] 1. An upper lid structure for a carbonated beverage can that can withstand internal pressure due to carbon dioxide, which is a feature of carbonated beverages, and open an opening area having a diameter of the upper lid with a pull-top. 2. A carbonated beverage can with a handle formed by an upper lid and a tab.
