A mode for carrying out the present invention is shown below. The present invention is a beverage can 1 for drinking water filled with a beverage in which the can body 20 is sealed with at least one or more can lids (upper lid 3, lower lid 30), and the can lid and the can body 20 are connected in series. It forms the recess 50 of the above.

Specifically, at least one series of recesses 50 extending from the outer peripheral side surface of the can lid (upper lid 3) to the outer peripheral side surface of the can body 20 in the axial direction is formed. That is, a series of recesses 50 are formed by the recesses of the can lid (the recesses 5 of the upper lid and the recesses 35 of the lower lid) and the recesses 25 of the can body. The beverage can 1 is mainly made of a material such as aluminum or iron, and is filled with beverages such as coffee, black tea, Japanese tea, juice, carbonated beverages, beer, and chuhai. It will be.

FIG. 1 is a perspective view illustrating each beverage can 1 of the present invention. Generally, as the beverage can 1 which is a beverage container, there are a two-piece can and a three-piece can. The two-piece can is composed of, for example, a bottomed cylindrical can body 20 and a disk-shaped can lid that seals the opening side of the can body 20. The three-piece can is composed of, for example, a pair of disk-shaped can lids and a cylindrical can body 20 which is a separate member, and both opening sides of the cylindrical can body 20 are sealed with a pair of can lids. Stop. In FIG. 1, the right beverage can 1 is a two-piece can, and the center and left beverage cans 1 are three-piece cans.

In the present embodiment, in the case of a two-piece can, the can lid provided with the drinking spout portion 19 is referred to as an upper lid 3, and in the case of a three-piece can, the can lid provided with the drinking spout portion 19 Is a pair with the upper lid 3 and the upper lid 3, and the can lid on the bottom side opposite to the upper lid 3 is referred to as a lower lid 30.

A series of recesses 50 are formed in the beverage can 1 in the axial direction. In the case of a two-piece can, a series of recesses 50 are formed in the axial direction from the upper lid 3 of the beverage can 1 to the lower part of the can body 20. That is, a straight recess is formed from the outer peripheral side surface of the upper lid 3 to the lower side of the outer peripheral side surface of the can body 20. In this case, a series of recesses 50 are formed from the recess 5 of the upper lid to the recess 25 of the can body. In the case of a two-piece can, even if the squeezed portion 23 above the can body 20 is provided with a recess, the squeezed portion 23 is not provided with a recess as in the beverage can 1 on the right side of FIG. There may be.

In the case of a three-piece can, a series of recesses 50 are formed in the axial direction from the top lid 3 of the beverage can 1 to the can body 20. That is, a straight recess is formed from the outer peripheral side surface of the upper lid 3 to the outer peripheral side surface of the can body 20. In this case, a series of recesses 50 are formed from the recess 5 of the upper lid to the recess 25 of the can body. Further, it is also conceivable to form a recess 35 of the lower lid on the outer peripheral side surface of the lower lid 30 as in the beverage can 1 on the left of FIG. 1. In this configuration, the recess 5 of the upper lid, the recess 25 of the can body, A series of recesses 50 are formed over the recesses 35 of the lower lid.

In the case of a configuration in which the lower lid recess 35 is not formed on the outer peripheral side surface of the lower lid 30 as in the beverage can 1 in the center of FIG. 1, the upper lid 3 to the can body 20 of the beverage can 1, that is, the recess 5 of the upper lid A series of recesses 50 are formed only over the recesses 25 of the can body. However, with such a configuration, the lower lid 30 has a circular shape, so that the beverage can 1 can be stably placed. it can.

The number and position of the series of recesses 50 are not limited. In terms of number, at least one series of recesses 50 are formed at positions facing the spout 19. In other words, the recess 5 of the upper lid connected to the recess 25 of the can body and the drinking spout 19 face each other. The axial length of the recess 25 of the can body does not matter. It may be from the upper lid 3 side to the lower lid 30 side, or up to about the middle of the can body 20.

In addition, a configuration in which a plurality of series of recesses 50 are formed can be considered. As an example, for example, it is conceivable to form five series of recesses 50 of a first recess 51, a second recess 52, a third recess 53, a fourth recess 54, and a fifth recess 55 in the circumferential direction of the beverage can 1. Be done. When five series of recesses 50 are formed in this way, a series of convex portions 60 connected next to each series of recesses 50 can image petals, and when viewed in a plan view, they are shaped like cherry blossom petals and look like cherry blossom petals. It can bring out gorgeousness (see Fig. 2).

Here, the series of convex portions 60 are the convex portion 61 of the upper lid in the case of a two-piece can and a three-piece can, the convex portion 62 of the can body, and the convex portion 61 to the lower lid of the upper lid in the case of a three-piece can. It is formed by a convex portion 63. Although not shown, a notch may be made in the convex portion 61 of each upper lid in the series of convex portions 60 in order to give a stronger image of cherry blossom petals.

As shown in FIG. 2 and the like, when five series of recesses 50 are formed, for example, the series of recesses 50 facing the drinking spout 19 of the upper lid 3 is designated as the first recess 51, and the first recess 51 is designated as the first recess 51. As a reference, the second recess 52, the third recess 53, the fourth recess 54, and the fifth recess 55 are set clockwise. The pitch between the first recess 51 and the fifth recess 55 is not limited to equal intervals, and may be unequal intervals.

Further, among the first recesses 51, the recess 5 of the upper lid on the outer peripheral side surface of the upper lid 3 may be configured to be inclined inward (toward the drinking spout 19 side) (see FIG. 3). Further, not only the concave portion 5 of the upper lid but also a part of the concave portion 25 (upper lid 3 side) of the can body connected to the concave portion 5 may be inclined. The inclination angle may be any angle as long as it is easy to drink and easy to pour.

The upper lid 3 itself may be inclined. Specifically, the upper lid 3 is tilted from the opposite side of the drinking spout 19 side to the drinking spout 19 side. By inclining the upper lid 3, for example, when pouring drinking water into another container such as a cup, air is less likely to collide with each other in the drinking can 1 near the drinking spout 19, and drinking water is less likely to scatter. Become. Further, when the air hole 9 is opened, the drinking water will be discharged more smoothly due to the synergistic effect.

By forming a series of recesses 50 in this way, the beverage can 1 itself can be firmly gripped. Further, the series of concave portions 50 and the series of convex portions 60 make it difficult for the beverage can 1 itself to roll. Furthermore, even when a plurality of beverage cans 1 are stacked side by side, they are less likely to fall off. A conventionally known method can be applied to the formation of the series of recesses 50.

As illustrated in FIGS. 2 and 7, regarding the location where the contents of the beverage can 1 come out, that is, the opening structure of the drinking spout 19 when drinking a beverage, a well-known pull-top structure, mainly an easy open end. Use structure. That is, a pull tab 10 is provided at the end of the drinking spout 19 of the upper lid 3 via the rivet 17, and a score 19a (cut) is made along the outer edge of the drinking spout 19, and the score 19a is made with the rivet 17 as a fulcrum. When the pull tab 10 attached to the rivet 10 is triggered, the score 9a is gradually cut, and finally the rivet portion 19 is opened (see FIG. 8). Therefore, by raising the pull tab 10 in both the two-piece can and the three-piece can, the drinking spout 19 of the upper lid 3 is opened, and the beverage that is the filled content is transferred directly from the drinking spout 19 or to a cup or the like. You can drink.

The size, shape, and depth of the score 19a of the mouthpiece 19 can be arbitrarily selected, and any size, shape, and depth can be used as long as the effects of the present invention can be achieved. Good. Similarly, the shape, size, and the like of the pull tab 10 can be arbitrarily selected.

As another configuration, for example, among a series of recesses 50, a configuration in which a protrusion is provided in the recess 25 of the can body of the first recess 51 facing the drinking spout 19 (not shown) can be considered. The size and number of the protrusions, the distance between the protrusions when a plurality of protrusions are provided, and the like do not matter. Further, the position where the protrusion is provided may be any position as long as it is the recess 25 of the can body.

According to such a configuration, for example, a visually impaired person can confirm the position of the drinking spout 19 by touching the protrusion with a finger or the like. In addition, the position of the mouthpiece 19 can be confirmed without actually visually confirming the position of the mouthpiece 19 even in the dark.

Further, an air hole 9 can be formed in the upper lid 3 with the rotatable pull tab 10. That is, by rotatably providing the pull tab 10 at the end of the drinking spout 19 of the upper lid 3 via the rivet 17, the pull tab 10 can be rotated around the rivet 17 (see FIG. 9). In other words, the spout portion 19 containing the score 19a and the pull tab 10 can be partially connected via the rivet 17 to rotate the pull tab 10. Then, the area where the pull tab 10 can be rotated is set as the rotation area 45, the air hole 9 is provided in the rotation area 45, and the air hole 9 can be opened in the upper lid 3 by the pull tab 10 (FIGS. 10 and 11). Etc.). Hereinafter, the structure for opening the air hole 9 will be described.

As shown in FIG. 11, it is conceivable that the air hole 9 is opened by breaking the drilling rod 6 provided in the upper lid 3. Specifically, for example, it has the following configuration. A drilling rod 6 is provided so as to project from the upper lid 3 of the rotation region 45 of the pull tab 10. Further, a score 9a along the air hole 9 is inserted into the upper lid 3 around the protruding piercing rod 6. Then, when the pull tab 10 is rotated with the rivet 17 as a fulcrum, the side surface 10b of the pull tab 10 hits the abdomen 6a of the piercing rod 6, and when the pull tab 10 is further rotated, the score 9a is gradually cut as the piercing rod 6 collapses. Enters. That is, when the piercing rod 6 is tilted, a crack is formed in one place of the score 9a in conjunction with this, a notch gradually enters the circumferential direction from the crack, and finally the air hole 9 is opened. In this way, the air hole 9 can be opened in the upper lid 3 by folding the piercing rod 6 protruding from the side surface 10b of the pull tab 10.

The drilling rod 6 projects above the air hole 9 before the opening (breakage), and the bottom surface of the drilling rod 6 may have a diameter smaller than or substantially the same as the score 9a. The drilling rod 6 may have any shape, such as a substantially conical shape with a partially missing tip, a straight shape, and a shape that gradually narrows toward the tip side. In the case of a shape that gradually narrows toward the tip side, the abdomen 6a of the piercing rod 6 is inclined, so that the piercing rod 6 may be easily broken.

The score 9a along the outer edge of the air hole 9 has a structure for facilitating the opening of the air hole 9 as well as the score 19a inserted along the spout portion 19, and if the air hole 9 can be easily opened, It may have any structure. Further, the position of the drilling rod 6 for opening the air hole 9 may be any position as long as it is on the rotation region 45 of the pull tab 10 of the upper lid 3. For example, an air hole 9 can be provided at a position facing the third recess 53 and the fourth recess 54.

Further, in addition to the configuration provided with the drilling rod 6 for opening the air hole 9, the portion where the air hole 9 is formed in the upper lid 3 is thinner than the other portions, that is, a part of the upper lid 3 of the rotation region 45 of the pull tab 10 is formed. A thin-walled portion 8 is formed, and a protrusion 13 provided on the pull tab 10 has a sharp structure like a triangular corner, and an air hole 9 is opened by piercing the thin-walled portion 8 which is a thinned portion by this corner. It may be.

Specifically, the pull tab 10 provided with the protrusion 13 is rotated to a position where the air hole 9 is opened, and the score 9a can be broken and the air hole 9 can be opened by pressing the pull tab 10 (see FIG. 10). .. That is, when the pull tab 10 is pressed, the thin portion 8 is gradually cut by the protrusion 13, and finally broken to open the air hole 9.

The position for opening the air hole 9 in the upper lid 3 may be any position as long as it is on the rotation region 45 of the pull tab 10 of the upper lid 3. For example, an air hole 9 can be provided at a position facing the third recess 53 and the fourth recess 54. Further, the thinness of the thin portion 8 does not matter.

In the case of a configuration in which an air hole 9 is formed on the rotation region 45 of the pull tab 10, a protrusion 13 for opening the air hole 9 is provided below the outer end portion 13a of the pull tab 10, but the shape of the protrusion 13 is as follows. Can be in various shapes. For example, it can be any one of the semicircular shape of the front view of FIG. 6 (a), the triangular shape of FIG. 6 (b), the trapezoidal shape of FIG. 6 (c), and the square shape of FIG. 6 (d). .. Any shape may be used as long as the air hole 9 can be formed.

As shown in FIG. 5, a configuration in which a step is provided between the outer end portion 10a of the pull tab 10 and the outer end portion 13a of the protrusion 13 is also conceivable. Since this step is for facilitating the pull tab 10 to be easily raised, the pull tab 10 may be easily raised, and may be, for example, 1 mm or 2 mm or more.

The position of the pull tab 10 at the time of shipment or sale of the beverage can 1, that is, the position of the pull tab 10 shown in FIGS. 2 or 7, is set as the initial position, and the upper lid 3 at the initial position of the pull tab 10 has a protrusion 13 It is also conceivable to provide a storage portion 7 (see FIG. 9) capable of accommodating the above, or a protrusion (not shown) so that the outer end portion 13a of the protrusion 13 cannot come into contact with the storage portion 7.

In addition, with respect to the opening of the air hole 9, a pull-top structure similar to the opening of the drinking spout 19 can be adopted (not shown). That is, a pull tab for opening the air hole 9 was provided at the end of the air hole 9 via a rivet, and a score (cut) was made along the outer edge of the air hole 9 and attached to the score with the rivet as a fulcrum. When the pull tab for opening the air hole 9 is caused, the score is gradually cut, and finally the score is broken to open the air hole 9.

By opening the air holes 9, air enters through the air holes 9 when pouring the beverage, whereby the beverage as the content smoothly exits from the beverage can 1, especially in the case of beverages such as beer and low-malt beer. Even when the air from the air hole 9 is poured into a glass or the like, the amount of bubbles is appropriate, and the taste and appearance are improved.

Beverage cans such as steel cans and aluminum cans are recycled resources and reused, but there are rules for each region when collecting them, and the beverage can 1 is lightly washed with water before being put in the collection box. Rules may be set. In such a case, since the water flows quickly from the drinking spout portion 19 due to the presence of the air hole 9, it is possible to save time when washing the beverage can 1 with water.

The size and shape of the air hole 9, the depth of the score, the thinness of the portion of the upper lid 3 where the air hole 9 is to be formed, and the like can be arbitrarily selected, and what if the effect of the present invention can be achieved? It may have any size, shape, and depth. For example, the shape of the air hole may be any shape such as an ellipse as well as a circular shape as shown in FIG.

Although the pull tab 10 itself can rotate 360 degrees, the rotation range 45 of the pull tab 10 of the upper lid 3 is preferably within a range of 180 degrees (90 degrees to the left and right from the initial position), and more preferably. , 90 degrees (45 degrees to the left and right with the initial position as the base point) within the region (see FIG. 9).

Even when the pull tab 10 is rotated, the air hole 9 can be reliably opened by holding a finger in the third recess 53 or the fourth recess 54. That is, when the beverage can 1 is grasped by the right hand and the air hole 9 is opened by the left hand, the index finger, the middle finger, and the ring finger of the right hand can firmly grasp the beverage can 1 by sandwiching the third recess 53. Yes (see Figure 4). Similarly, when the beverage can 1 is grasped with the left hand and the air hole 9 is opened with the right hand, the index finger, the middle finger, and the ring finger of the left hand firmly grasp the beverage can 1 by sandwiching the third recess 53. be able to.

Depending on the beverage can 1, an annular groove 4 may be formed on the surface of the upper lid 3, but after the beverage that is the filling of the beverage can 1 has been once drunk or after the beverage has been poured, the beverage can be filled in the annular groove 4. May remain. Then, when the beverage can 1 is moved, a small amount of beverage remaining in the annular groove 4 rotates in the circumferential direction. However, if dust or the like is accumulated in the annular groove 4, the annular groove 4 is used. The remaining trace amount of the beverage rotates in the circumferential direction to become a beverage containing dust, dust, etc., and when drinking again, the beverage containing dust, dust, etc. is to be drunk.

In order to avoid such an unsanitary situation, it is conceivable that the annular groove portion 4 is closed by the recess 5 of the upper lid. As a specific configuration, by inclining the second recess 52 and the fifth recess 55 inward (the drinking spout 19 side), the annular groove 4 located in the second recess 52 and the fifth recess 55 is formed on the upper lid 3. It is possible to prevent the beverage containing dust, dust, etc. from rotating in the circumferential direction by blocking the concave portion 5 of the upper lid on the outer peripheral side surface.

In addition, although not shown, there is also an example in which a series of recesses 50 are formed in the beverage can 1 in which the mouthpiece portion when drinking a beverage is sealed with a screw cap. The beverage can 1 referred to here is a metal or aluminum bottle-shaped container generally called a bottle can, and is a two-piece type composed of a combination of two parts, a cap and a can body, and a cap. There is a three-piece type that is composed of three parts, a can body and a lower lid.

The can body is composed of a main body and a neck connected to the main body. A screw groove is drilled in the neck portion, and a screw groove is also drilled inside the cap. The caliber of the neck is smaller than the body diameter of the main body.

Then, at least one or more series of recesses 50 extending in the axial direction on the outer peripheral side surface of the can body are formed. The other common parts have the same configuration as the described examples.

Although the present invention has been described above based on each example, the present invention is not limited to the above-mentioned examples, and changes may be made to each example without departing from the spirit of the present invention. The described techniques or other known or well-known techniques may be combined.
