Description

Triangle

The present invention relates to a triangular can that allows the contents to fold the empty can body flat.

In general, cans containing soft drinks, mixed juices, or alcoholic beverages such as beer have a circular shape, and the conventional cans have a circular shape. It has a relatively strong strength to prevent crushing.

However, when the cans are discarded after emptying the contents contained in the cans, it has been pointed out that a large quantity of the cans cannot be transported at the time of collection, so that the can body is smoothly solved. It has to be crushed, but the circular can body itself is so strong that it can not be easily crushed by small force, and most users have a closed end that can be discarded without reducing the volume of the can body after cooling the contents of the can. There was a problem that followed many difficulties in the collection process.

And the conventional circular cans as described above, when the contents are pulled out through the opening formed in the sealing plate, the contents are not drawn out into one place but flow down to the left and right, so that the contents flow down to the edge of the mouth and fall into the garment. In order to eliminate the closed end, the can was manufactured in a triangle, and was introduced in Korean Utility Model Publication No. 1534 as Publication No. 92-172.

However, the triangular can of the preceding design also has a problem that can not easily crush the can body.

The present invention devised to solve the above problems, the can is made into a triangle, but the structure to form a bent line on the can body after emptying the contents after the user himself folded the can body with a small force Its purpose is to reduce the volume of the can body to a minimum, so that more cans can be collected in a certain sized cans and can be transported for disposal at a time. In addition, it is another purpose to sanitarily open the opening formed in the sealing plate of the triangular can and to eat and drink the whole quantity without leaving or spilling the contents.

The present invention as a means for achieving the above object, in the triangular can can be made of the can body in a triangle, and the opening cutting line for cutting the opening to the upper sealing plate and the opening handle for breaking the opening cutting line, A concave bent line divided into three surfaces of the can body into a folding surface, a pressing surface, and a flat surface, and vertically formed at the center of the folding surface;

Concave inclination curves connected to the upper and lower portions of the concave bending line and inclinedly extending to corners of both sides of the flange of the upper and lower sealing plates formed on the corresponding folding surface;

Iron extension curves that have the same inclination angle as one of the concave inclination curves and extend in an inclined line; And

A concave extension curve adjacent to the ends of the convex extension curves and extending obliquely to a far corner of a flange formed on the pressing surface adjacent to the folding surface;

It is characterized in that the pressing surface of the can body by pressing the folding surface, the vertical concave curve formed on the folding surface can be folded inward while the can body can be folded smoothly.

And when the can body is folded flatly, the upper and lower sealing plate member has another feature to be folded flat over the pressing surface for folding the folding surface flatly, and also one side triangular corner portion of the upper sealing plate member of the can body Another feature is to form a triangular unopened cutting line and attach a triangular unsealed handle with a bending protrusion to press and fracture the triangular tip of the unsealed cutting line.

Reference numeral 1 denotes a can body, and the can body 1 is formed into a triangle and is divided into a folding surface 1a, a pressing surface 1b and a flat surface 1c.

The upper and lower portions of the can body 1 constitute upper and lower flanges 2a and 3a by coupling with upper and lower sealing plates 2 and 3.

In the center of the folding surface 1a of the can body 1, a concave bent line 11 is formed to a position close to the upper and lower flanges 2a and 3a, and the concave bent line 11 is formed by pressing. It is bent to the inside of the main body 1, and the folding surface 1a itself is in charge of acting to be folded in half toward the inside.

Also, the upper and lower portions of the concave bent line 11 are concave inclined curves 12a, 12b, and 13a extending symmetrically to both corner portions of the upper and lower flanges 2a and 3a of the folding surface 1a. ) 13b is connected to each other, and the above-mentioned concave inclination curves are all press-processed to be folded into the can body 1.

In addition, at the point where the upper and lower portions of the concave curve 11 and the concave inclination curves 12a, 12b, 13a, and 13b meet each other, a separate iron extension curves 14a and 14b are formed. The convex extension curves extend in a straight line with one side concave inclination curves 12b and 13b to extend to corner portions of the folding surface 1a and the pressing surface 1b, and the convex extension curves They are processed to be bent toward the outside of the can body 1 to induce folding outward.

On the pressing surface 1b of the can body 1, two lines of concave extension curves 15a and 15b are symmetrically formed, and one end of the concave extension curves is the folded surface 1a and the pressing surface ( It extends from the corner part of 1b) to the extending | stretching curve 14a, 14b in the state which inclined toward the opposite side, and continues to the corner part of the far flange.

And the flat surface 1c which comprises the can main body 1 plays the role of a support surface when folding the folding surface 1a and the pressing surface 1b.

On the other hand, the opening part 21 and the opening handle 4 are installed in the upper sealing plate material 2 of the upper and lower sealing plate materials 2 and 3 couple | bonded with the upper and lower sides of said can body 1 above.

The opening portion 21 is composed of an opening cut line 21a formed in a U-shape adjacent to a triangular corner portion of the upper flange 2a and a concave bending line 22 connecting both ends of the opening cut line. The opening part 21 has a triangular opening handle 4 attached to the opening portion 21 by a rivet 41, and a bending protrusion 42 for pressing the end of the opening cutting line 21a is provided at the triangular end of the opening handle 4. At the end of the opening handle 4, an arc-shaped protrusion 43 is formed to facilitate gripping.

Referring to the operation of the present invention configured as described above are as follows.

In the present invention, the can body 1 and the upper and lower sealing plates 2 and 3 are processed in separate processes as shown in the example of FIG. 2, and then the can body 1 is formed into a triangle, and then the upper and lower sides are The sealing plate (2) and (3) in turn draw processing to produce a triangular can filled with the contents, wherein the opening handle (4) is bound to the upper sealing plate (2) with a rivet (42).

After opening the opening portion 21 (opening state of the opening portion will be described later) by using the opening handle 4 mounted on the upper sealing plate 2 of the triangular can manufactured as described above, the can body ( When the volume of 1) is to be minimized, the pressing surface 1b of the can body 1 may be pressed once.

That is, in the state as shown in FIG. 3, the force is applied from the pressing surface 1b side, and the corner portion adjacent to the folding surface 1a is applied to the folding surface 1a with a finger (thumb thumb). When the folding surface (1a) is bent inwardly by the action of bending the concave curved line 11 is formed in the center of the folding surface (1a) itself begins to be folded inward (see Figure 4: in this case the user When the double finger holding the can body serves as a pressing operation on the outside of the folding surface, the folding action becomes easier). Thus, the pressing surfaces 1b which start to fold the folding surface 1a are formed on both sides thereof. The concave convex extension curves 15a and 15b are in a state in which a force can be continuously applied to the folding surface 1a side by the action of folding inwardly, and the concave extension curves 15a and 15b are The iron extension curves 14a and 14b which are connected to each other fold the folding surface 1a. It is to be folded to the outside and simultaneously the inclined inclination curves 12a, 12b, 13a, 13b connected to both ends of the concave bending curve 11 induces the action of bending inward Folded surface (1a) is to proceed to the folding operation as shown in the example of Figure 5, at this time, the concave inclination curves (12a, 12b), (13a) formed on the folding surface (1a) and the pressing surface (1b) ), The upper and lower sealing plates (2) and (3) are not deformed by the folding action of the 13b, the convex extension curves 14a and 14b, and the concave extension curves 15a and 15b. It is folded flatly to the pressing surface 1b in the state. (Refer FIG. 6).

As described above, the folding surface 1a itself is completely flat between the flat surface 1c and the pressing surface 1b only by applying a force to the folding surface 1a toward the pressing surface 1b of the can body 1. Half and the upper and lower sealing plates 2 and 3 are also pressed flat on the pressing surface 1b, so that the entire tripod can is folded flat.

Next, when the opening part 21 formed in the upper sealing plate member 2 of the triangular can is described, the opening of the opening handle 4 as shown in the example of FIG. 8 is under the arc-shaped protrusion 43 protruding upward. When the finger tip is pushed up and lifted up, the opening handle 4 itself acts as a seesaw around the rivet 41, so that the triangular tip portion presses the opening 21, wherein the opening handle 4 Since the bent protrusion 42 formed at the tip is pressed against the triangular tip of the tear-off line 21a, the tip of the opening 21 starts to be opened while being broken down (see FIG. 9). Thus, the tip of the opening 21 is thus opened. When the user pulls the opening handle 4 in the opened state, the tear line 21a of the opening portion 21 is fractured to the yaw bending line 22 and stops. The opening part 21 opened up to the concave bending stop line 22 by this action is completely opened in a substantially Z shape toward the upper sealing plate 2 without being immersed into the can.

As described above, since the opening part 21 is opened upward, a case in which foreign matter such as dust, which is buried in the upper surface of the opening part 21, is dissolved in the contents before the opening part 21 is opened.

In addition, the eight-shaped tear line 21a of the opening part 12 is formed adjacent to the triangular corner portion of the flange 2a, so that there is no case of dispersing to the left and right when the contents are spilled, so that the whole amount is not spilled or left during food and beverage. You can do it.

According to the present invention as described above, when the user discards the can body after cooling the contents of the triangular can, the user himself can fold the can body smoothly to minimize the volume while collecting and storing a large amount in the can collection. It can improve the collection efficiency and transportation efficiency of the can, and also increase the recycling rate of the can, thereby contributing to the recycling of resources. It is a very practical design that has the effect of making the food more hygienic and the food can be eaten without spilling or leaving the contents and the food can be eaten without spilling or leaving the contents.

The present invention is to provide a triangular can to facilitate the disposal process while minimizing the volume by folding the empty can body of the contents.
