Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an aluminum beverage can that is opened by a cutter lever that is opened by pressing a lever with a cutter when opening the beverage can.

[0002]

[Prior art]

 In the past, when opening a can of coffee, beer, or carbonated soft drinks, a tab that was difficult to pinch was raised, and then the tab was returned. Therefore, the opening did not go straight and quick opening was not desired, and it took time. The upper lip nose was pressed against the drinker's lateral lips, and the upper lip was squeezed by 4 to 5 mm from the circumferential edge of the can lid. There was a drawback that the remaining liquid could not be completely consumed unless the mouth was directed to the sky and it was tilted more than 60 degrees from the horizontal.

[0003]

[Problems to be solved by the device]

 When the conventional beverage can is opened and drinks, the present invention does not fit because it does not fit the lip of the drinker's lateral ellipse because the opening is vertical elliptical. Moreover, the can edge and the opening edge were separated by about 5 mm, and after finishing drinking in a horizontal state, a large amount of residual liquid remained. In addition, it took time to pull up the tab of the tab of the tab, and it took time to put it back and forth, and when the tab was pressed, the tab pressed against the narrow opening of the nose and upper lip. The purpose is to provide aluminum beverage cans with open openings.

[0004]

[Means for Solving the Problems]

 According to the present invention, a perforated cone 1, a cutter 2, and a lever 3 for cutting a can lid are integrated with the back surface of a circular can lid for a cylindrical beverage can, and a supporting shaft rivet 4 is attached to the other end of the lever. Also, attach the pull arm 5 that can be pulled out easily by levering and levering. On the outer surface of the can lid, the tab receiver 7, which raises the tab 6 and the tab 6 and pushes the cutter 2, is provided with the cutter cover 8 which is integrated with the cutter 2 lever 3 in the front part of the hole. 1, prevent the damage of the cutter 2. The shape of the mouth, which is the mouthpiece, is a horizontal ellipse that fits the lips, and the edge of the mouth is located extremely close to the rim of the can lid.

[0005]

[Action]

 Since the present invention has taken the above-mentioned means, when it is used, it is raised by picking up the end of the tab 6 of the can lid, in which case the tip of the tab located at the end of the cut groove 10 is at the cut groove end. Firmly squeeze and press the tab 6 until it completely stands up to the tab receiver 7 and bring them into close contact. At the same time, the tab tip part separates the tab receiver, the cutter cover 8 and the drill cone 1 by a slight lever action to separate the lifted welding part. The tip of the drilling hole first penetrates the end of the incision groove inside the can, and the cutter 2 below it also has the position of the first incision at the end of the incision groove. The drilling cone and the cutter should be rigid, and the incision groove should be processed with the normal thickness of 0.14 mm thick canning aluminum. The tab receiver 7 is integrated with a hazard-preventing cutter cover 8 at the front portion, and is integrated with a drill cone, a cutter, a cutter lever, and a lever support shaft rivet 4. The cutter is applied with a force to make an incision at the bottom of the groove. The lever slides on the back of the can lid by pressing the pull arm 5. The U-shaped part under the cutter slides the bottom wall of the groove. On the other hand, the opening 9 of the drinking spout has a horizontally elongated elliptical shape that fits the lip of the can lid, and is pulled off by a pull arm strongly welded to the back surface of the can lid as the lever 3 advances. This action causes the lever 3 to be housed in the upper recess of the pull arm, and the rear surface of the can lid and the upper surface of the arm are gradually slid, and finally opened in a relation of work = F (force) × cos θ (displacement angle). In addition, the cross section of the pull arm has a mountain-like shape in the middle part, and has a rigid structure for strength. When the tab is pushed all the way to the end of the incision groove, the lid of the spout 5 is completely pushed down into the can.

[0006]

【Example】

 Embodiments shown in the drawings will be described in detail below. In this embodiment (aluminum beverage can with an opening by a cut lever), as shown in Fig. I, since the lid part of the mouth of the opening is pulled off by the pull arm on the back of the can lid, the attached end of the pull arm is Secure with strong welding. The pulling force of the pull arm trips the opening by the movement of the lever with the lever that intersects with it, that is, work = F · cos θF is the force and Scos θ is the opening according to the displacement angle formula.

As shown in FIG. 3, initially, the pull arm is recessed only at the position where it intersects with the lever, is housed on the arm, and is pushed downward by the movement of the lever. The right edge of the pull arm has a chevron section and is rigid and does not bend. When the lever moves, slide on the back of the can and push down on the pull arm.

As shown in FIG. 4, a cutting groove is provided on the rear surface of the can lid to allow the cutter to cut, and the section is a trapezoidal shallow type. The right end of the lever is U-shaped along the left outer wall of the groove, and the U-shaped rising edge. The part is a cutter, and the upper part is provided with a drilling cone. It is located on the front wall at the beginning of the incision groove, and the drilling cone makes a hole in the front wall of the groove as the lever moves. At the same time, the cutter incises the front wall and then the groove bottom. It is pushed all the way to the end. At this time, the pull arms work as shown in FIG.

As shown in FIG. 6, a cutting groove is exposed on the outer surface of the can lid, and a cutter cover integrated with an internal cutter, a tab receiver, and a tab for advancing the pressing are provided. It is located in front of the wall of the groove with the structure of both legs, and when the tab is picked up and is upright, the welding of the can lid is tripped off by the tab receiver, the tab receiver is pushed forward, the drill cone, and the cutter cover immediately before the cutter tab receiver is pressed. Advance. The cutter cover moves forward by sitting on both edges of the groove with a cutter and a cone danger prevention device, and the sliding of the lever back of the can and the sliding of the cutter cover work stably due to the narrowness of the inner and outer surfaces of the can lid. As shown in FIG. 12, the lever has a slightly curved center portion, which has a smooth action for crossing the arms, and a flexible cutter action. As shown in Fig. 8, the plate surface of the arm is slightly curved in order to make it easy to pull out the mouth opening with the cut line.

[0010]

[Effect of device]

 In the present invention, when opening a beverage can, a tab is attached to the center of the surface of the can lid to give a grotesque appearance as in the conventional case, and the tabs of the tabs are closely attached, making it difficult to pick up. The tab is deformed by the tab rivet even if it is not broken and it touches the nose of a person, causing discomfort, and the opening is a vertical ellipse. It does not fit in the lateral ellipse of the lips, and is separated by about 5 mm around the lid of the can, so when you finish drinking it there is some liquid left over even if the can is leveled up, and the face is raised upwards and tilted more than 60 degrees from the horizontal. Without it, I couldn't completely drink up to the last drop. The present invention incorporates the opening device into the inside as much as possible and has a neat appearance. When the drink is taken, the tab does not obstruct and the opening fits to the lips and is horizontal and there is no residual liquid. It can be opened quickly and quickly with one stroke.
