Description

In the present invention, a pull top is often used for beverage cans and food cans. Place the finger on the pull top and open it along the score provided on the pulling can. Generally, it is said to be a pull-top canned food. In the can manufacturing industry, it is said to be an easy open end. There are two types of easy open ends: partial open ends and full open ends.
The partial open end is used for beverages such as can juice, and only a part of the lid opens. The full open end is said to be an easy open can, and the entire lid of the can is removed. Both cans warn the local government because they hurt their nails when they put their fingers on the pull top and injuries with the lid that opened the easy open can. It relates to a pull-top opener that can be used safely by helpless elderly people and children.

  Provided is a can opener for peeling a solid can top cover in a safe, simple and quick manner for a solid sealed can with a pull top. The structure is composed of a three-part product consisting of a rod-shaped L-shaped main rod 1, a handshake 2 extending at one end thereof, and an L-shaped rod-shaped pull-top tab rod 3 specially provided from the central region of the main rod. A serrated concave portion which is engaged with the peripheral edge S of the main hook end region 1a and serves as a saddle fulcrum so that the upper surface Q of the sealed can C having different diameters can be easily peeled off for a series of operations when opening the can. 4 is provided, and the L-shaped ridge-shaped pull-top tab 抉 楊 杆 3 is formed with a bottom portion 3c for holding the pull-top tab S so that the sealed can can be easily opened and the can top surface Q can be cleaved and peeled off. The open end 3a has a thickness of about 1 to 2 mm, and a tapered surface 3b is formed so as to extend in the depth direction of the bowl-shaped portion. (For example, refer to Patent Document 1).

  Provided is a can opener capable of opening an easy open can easily, particularly smoothly. It is a can opener 1 that gives an opening action to a tab 22 attached to a can lid 21 of an easy open can, and includes an insertion tongue 2 that can be inserted into a ring 25 of the tab 22, and an insertion tongue 2 It is provided with a rolling part 3 that is arranged rearward and can roll on the can lid 21, and a grip part 4 that can be gripped with fingers. According to this invention, since both the formation of the initial opening and the tearing of the score in the easy open can can be performed with the same instrument, the number of members can be reduced and the handling is easy. Since the opening is performed using the lever action, a large static force that is enlarged can be applied to the opening, and the opening operation becomes extremely smooth. Thus, according to the present invention, a can opener that can open an easy open can easily and particularly smoothly can be obtained. (For example, refer to Patent Document 2).

  Easy-open cans (pull-top canned foods) are used for a wide variety of cans because of their convenience. This ease has led to accidents when opening cans, and the Center is consulted every year. One of the most common is that it was difficult to open, so if you put in force, it opened at once and you were injured by sewing several hands on the hand holding the can. This is because the operation was performed without reading the explanation on the can. We have provided information because we tested the difference in how to open the can. (For example, refer nonpatent literature 1).

The partial open end is used for beverages such as can juice, and only a part of the lid opens. The full open end is said to be an easy open can, and the entire lid of the can is removed. Both can damage your nails when you put your finger on the pull top, or you can get injured by the open lid of the easy open can. It is opened along a notch called a score shape provided on the lid of the can. There is a company that is nicknamed “Pac Can” because it makes a pricking sound when a finger is caught on the ring of the tab of the pull top and the upper lid of the can is opened.
In particular, opening an easy-open can requires force, and elderly people and children cannot open it because of insufficient power. Moreover, even an adult healthy person is easily injured by the lid of the opened can and the inner can of the can.
Japanese food can standard No. 1 to 2 cans, flat 1 cans to flat 2 cans, crab 2 cans, mushroom 4 cans, tuna 1 cans, tuna 2 cans, tuna 2 kg cans, It is unclear if a tab is attached to a can with a pocket No. 2, a pocket No. 3, or other can with an inner diameter of 80 mm or more, but if it is an easy open can, There is power to do. There should be tools that can be used safely by helpless elderly and children.

Three types of can openers have been proposed (in the case of Patent Document 1).
It consists of a three-part goods consisting of a rod-shaped L-shaped main rod 1, a handshake 2 extended at one end thereof, and an L-shaped rod-shaped pull-top tab rod 3 specially provided from the central region of the main rod.
A tapered surface 3b is formed at the tip portion of the L-shaped hook-shaped pull-top tab bar 3 provided from the central area of the main bar. Inserting the tapered surface 3b into the tab of the can is easy for an adult healthy person but impossible for an elderly person or a child. Assuming that you can insert it into the tab, apply the serrated recess 4 that will serve as a fulcrum to the can and keep it from moving. At the same time, it is not easy to prevent the contents of the can from popping out so that the entire surface of the upper lid is removed. In this proposal, 1) the positioning of the can to be opened is easy, 2) the taper surface 3b can be easily inserted into the tab, 3) no force is applied after the tab is positioned There is a solution that can be manipulated and opened.

Two types of can openers have been proposed by a can manufacturing company (in the case of Patent Document 2).
A can opener 1 for giving an opening action to a tab 22 attached to a can lid 21 of an easy open can, and a plug tongue 2 that can be inserted into a ring 25 of the tab 22, and a plug tongue 2 It is provided with a rolling part 3 which is arranged and can roll on the can lid 21, and a grip part 4 which can be gripped with fingers.
According to this invention, the initial opening can be formed by inserting the tongue 25 into the ring 25 of the tab 22 in the easy open can, and the entire can can be torn from that state, so the number of members is small. Sumi, handling is easy for healthy adults. Since the opening is performed using the lever action, a large static force can be applied to the opening, and the opening operation can be smoothly performed by an adult healthy person. In this way, in the present invention, an easy open can can be easily and smoothly opened by a healthy adult person. It is impossible for the elderly and children. Assuming that the insertion tongue 2 can be inserted into the tab, the can opener 2 is inserted into the ring 25 while the can is not moved. Because it is impossible.
It is impossible for the elderly and children to keep the can's lid with the tabs so that the entire top lid can be removed so that the can's contents do not pop out. In this proposal, 1 is easy to position the can to be opened, 2 can be easily inserted into the tab 2, 3 to open the tab after the tab has been positioned There is power. There is a solution that can be operated and opened without effort. No. 1 cans and No. 2 European cans are not possible even for healthy adults.
