Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage bottle-shaped can filled with various beverages such as beer and carbonated beverages, and has an improved portion from the shoulder to the mouth of the beverage bottle-shaped can. is there.

[0002]

2. Description of the Related Art Conventionally, the diameter of a drinking bottle of a beverage-type bottle-type can having a re-plugging function is generally set to 28 mm (inside diameter 20 mm). In recent years, for bottle-shaped cans, a bottle-shaped can having a feature of easy pouring has been proposed and already sold, by widening the screw outer shape to 38 mm (inner diameter 30 mm).

Regarding the shoulder portion and the mouth portion of such a bottle type can for beverage, Japanese Patent Laid-Open No. 2000-72125 discloses a prior art. As the contents of this disclosure, when the inner solution is poured from the beverage bottle-shaped can, it drips to the outside of the beverage bottle, or the beverage residue that cannot be poured out pops out when handling an empty beverage bottle-shaped can. In order to prevent stains on clothes and the surroundings (drip / residual residue), there is a description of the angle of the slope that reduces the diameter from the can body of the beverage bottle type can to the drinking mouth, There is no mention of ease of drinking or pouring.

[0004]

In the conventional bottle type can for beverages, generally, a small drinking mouth is excellent in ease of drinking, but in terms of ease of pouring, conversely, the drinking mouth is large. Is said to be better.

That is, when the drinking mouth is small, it fits easily to the mouth, and the mouthpiece is attached to the mouth so that it is easy to drink. In addition, it is said that it is easy to drink when a large amount is to be drunk because the mouth can be held. On the other hand, if the mouth is large, the flow rate through the mouth increases and a smooth flow can be ensured,
You can speed up the process until you finish pouring the prescribed amount, making it easier to pour.

However, for children and women, if the drinking mouth is too large, the content liquid of the bottle-shaped beverage can overflows from the mouth, causing a problem that it is difficult to drink.

That is, in the case of a drinking mouth having a large diameter, since the mouth of the female and female is smaller than the mouth of the female and the drinking mouth extends beyond the mouth of the female and female, the content discharged from the drinking mouth If the amount of the liquid is large, the content liquid may spill.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a beverage bottle-type can that can improve the ease of swallowing and pouring of the liquid content of the beverage-type bottle can. To aim.

[0009]

In order to achieve the above-mentioned object, the invention of claim 1 has a re-plugging function and a gentle curved surface for narrowing from a cylindrical side wall to a mouth diameter. A bottle-shaped beverage can having a shape that forms a mouth portion from a shoulder portion, the direction of the mouth portion of the final inscribed line of the shoulder portion from the shoulder portion to the mouth portion, the direction of the drinking mouth It is characterized in that it is between the end and the cylindrical side wall.

According to the first aspect of the present invention, the direction of the mouth portion of the final shoulder-shaped inscribed line from the shoulder portion to the mouth portion is between the end portion of the drinking mouth and the cylindrical side wall. When tilting the beverage bottle-shaped can to a large extent and pouring it into a container such as a cup at a stroke, or when drinking directly with the mouth of the drinking bottle-shaped can, the liquid content discharged is Since it collides with the inner wall and the phenomenon is likely to occur around the entire circumference of the mouth, the inside and outside of the beverage bottle can are shielded to prevent air from entering the beverage bottle can. Therefore, it is possible to prevent discharge at once due to the negative pressure effect, and it is possible to suppress the pouring amount.

In particular, when the mouthpiece is formed to have a large diameter and a female or female person puts her mouth directly on the mouthpiece, the amount of the content liquid discharged from the mouthpiece is reduced, and the appropriate amount of the liquid is discharged. Therefore, it becomes possible for women and women to drink the content liquid without spilling, and convenience can be improved.

The invention of claim 2 is a bottle type for beverages having a shape of forming a mouth from a shoulder portion having a re-capping function and having an inclined surface for narrowing the diameter from the cylindrical side wall to the mouth portion. In the can, the direction of the mouth portion of the inner tangent line along the final shoulder shape from the shoulder portion to the mouth portion is between the end portion of the drinking mouth and the cylindrical side wall. It is a feature.

According to the second aspect of the present invention, the direction of the mouth portion of the inscribed line of the final shoulder shape from the shoulder portion to the mouth portion is between the end portion of the drinking mouth and the tubular side wall. Allows the beverage bottle-shaped can to be greatly tilted to pour into a container such as a cup at a stretch, or when the beverage bottle-shaped can is put directly into the mouth of the drinking bottle-shaped can, the liquid to be discharged is the inner wall of the mouth. When it collides with and the phenomenon occurs all around the mouth, the inside and outside of the beverage bottle can becomes blocked, and air is suppressed from entering the beverage bottle can. It is possible to prevent this from happening and to suppress the pouring amount.

Further, the invention of claim 3 has a re-plugging function, and has an inclined surface for narrowing down from the cylindrical side wall to the mouth diameter, and narrowed down inside the inclined surface just before reaching from the shoulder to the mouth. A beverage bottle-shaped can having a shape, wherein the direction of the mouth portion of the inner tangent line of the final shoulder shape narrowed down from the shoulder portion to the mouth portion is the end of the drinking mouth and the tube. It is characterized in that it is between the side wall.

According to the third aspect of the invention, the direction of the mouth of the final shoulder-shaped inscribed line from the shoulder to the mouth is between the end of the drinking mouth and the cylindrical side wall. Allows the beverage bottle-shaped can to be greatly tilted to pour into a container such as a cup at a stretch, or when the beverage bottle-shaped can is put directly into the mouth of the drinking bottle-shaped can, the liquid to be discharged is the inner wall of the mouth. When it collides with and the phenomenon occurs around the entire circumference of the mouth, the inside and outside of the beverage bottle can are shielded, and air is suppressed from entering the beverage bottle can. The liquid is prevented from being discharged, and the pouring amount can be suppressed.

According to the invention of claim 4, in addition to the structure according to any one of claims 1 to 3, the height of the mouth of the bottle type can is set in the range of 20 to 40 mm. It is a feature.

According to the invention of claim 4, in addition to obtaining the same effect as that of the invention of any one of claims 1 to 3, the bottle bottle can for beverages has a shape from the shoulder to the mouth. In addition to the configuration described in any one of 1 to 3, if the height of the mouth is set within the above range, it becomes easy to drink as a bottle-shaped can and at the same time pour easily.

That is, the constitution of the portion from the shoulder portion to the mouth portion of the bottle type can is the constitution described in any one of claims 1 to 3, and the height of the mouth portion is within the above range. In the case of outside, that is, when the height of the mouth is larger than 40 mm, air enters intermittently, which causes pulsation in the poured content liquid, which is not preferable. On the other hand, if the mouth height is less than 20 mm, the effect of suppressing the ingress of air cannot be expected.

Generally, if the drinking mouth is small, it is excellent in ease of drinking, but in terms of ease of pouring, conversely, the larger the drinking mouth is, the better. For this reason, it has been considered that a bottle-shaped can for beverages has a large drinking mouth and is easy to pour. This time, the shape of the beverage bottle can, especially the shape reaching the shoulder and mouth is determined by the inner diameter of the drinking mouth and the height of the mouth, providing a bottle bottle for drinking that is easy to drink and easy to pour You can

Further, the inner diameter of the drinking mouth and the height of the mouth portion are determined in advance according to convenience, and then the shape of the shoulder portion and the mouth portion is determined, whereby the ease of drinking and the ease of pouring are improved. Can be provided at the same time.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

As an example 1 which is an embodiment of the present invention, as shown in FIG. 1, a beverage bottle-shaped can 1 having a re-plugging function will be described.

That is, the beverage bottle-shaped can 1 is connected to the shoulder 3 having a circular arc-shaped cross section at the upper end of the cylindrical barrel body and connected to the shoulder 3. The outer peripheral portion is integrally provided with a mouth 4 for screwing a screw cap (not shown), and the lower opening end of the can body is sealed by a bottom member. Therefore, even after the screw cap is once removed from the mouth portion 4 of the beverage bottle-type can 1 and opened, the screw cap can be screwed into the mouth portion 4 and tightened again to be re-plugged.

The beverage bottle-shaped can 1 has a mouth portion 4
The outer diameter 7 is 33 mm, the inner diameter 6 of the mouth 4 is 25 mm, the height 8 of the mouth 4 is 30 mm, and the shape of the gentle shoulder 3 is 50 mm in radius.
The diameter of the curved bottomed cylindrical side wall 2 is 66 mm. In this case, with respect to the direction of the mouth portion 4 of the inscribed line C2 of the shape of the final shoulder portion 3 from the gentle shoulder portion 3 to the mouth portion 4,
It faces the inside of the beverage bottle-shaped can 1 from the mouthpiece 9.
Specifically, the inclination of the inner tangent line C2 with respect to the bottom surface of the beverage bottle type can 1 is lower than the position of the drinking spout 9.

The can body of the beverage bottle type can 1 is manufactured, for example, by forming a surface-treated steel plate or an aluminum alloy plate. That is, this can body part is formed by drawing and re-drawing or drawing and ironing a metal plate to form a cylindrical can body with a bottom, and then performing drawing several times on the bottom side of the bottom body. And the smoothing process to form the mouth portion 4 and the shoulder portion 3,
Further, the tip of the mouth portion 4 is cut and opened, the tip portion of the mouth portion 4 is externally wound to form a curl portion, a screw portion is formed below the curl portion, and a cap with a tamper evidence mechanism is provided (not shown). The body of the can is manufactured by forming an annular protrusion for fixing the breaking band (d). The bottle-shaped can 1 for beverage is manufactured by sealing the bottom of the can body with a bottom member. For this reason,
Mouth 4 formed by forming a metal plate
In addition, by further forming a screw portion or an annular protrusion, the inner peripheral surface of the mouth portion 4 extends along a direction substantially orthogonal to the flow direction of the content liquid flowing out through the mouth portion 4. Grooves are created to make them uneven.

The inner tangent line C2 is shown in more detail in FIG. In FIG. 2, the portion from the shoulder portion 3 to the mouth portion 4 of the beverage bottle type can 1 is shown in an enlarged manner. In FIG. 2, the shoulder portion 3 having a gentle curved surface for narrowing the mouth portion from the tubular side wall of the beverage bottle can 1 has a predetermined radius of curvature from the inside of the beverage bottle can 1 ( R1) is an intersection of the arc drawn with the outside of the beverage bottle can 1 and the arc drawn with a predetermined radius of curvature (R2), and a straight line extending along the intersection is the inscribed line C2. is there. The inclination of this inscribed line C2 is determined by the respective radii of curvature (R1, R
It will be determined by the size of 2) and the intersecting position.

In Example 1 of the present embodiment, the final inscribed line C2 of the shoulder 3 shape from the shoulder 3 to the mouth 4 extends in the direction of the mouth 4. As a result, the inclination of the inscribed line C2 with respect to the bottom surface of the beverage bottle-shaped can 1 intersects with the center line L of the beverage bottle-shaped can 1 in the mouth portion 4 and comes to the position of the end portion of the drinking mouth 9. That is, when the inner tangent line C2 is extended upward in the drawing, the extended portion contacts the outer edge portion of the drinking spout 9 without intersecting the central portion of the drinking spout 9.

The phenomenon that occurs when the internal solution is poured into the beverage bottle-shaped can 1 having the shape from the shoulder 3 to the mouth 4 as described above will be described.

That is, when the beverage bottle-shaped can 1 is greatly tilted and poured into a container such as a cup at a stretch, or when it is dipped directly in the mouth, the discharged content liquid collides with the inner wall 5 of the mouth 4. Moreover, since the phenomenon occurs over the entire inner circumference of the mouth portion 4, the content liquid in which the inside of the beverage bottle-shaped can 1 and the outside of the beverage bottle-shaped can 1 collide with each other as described above. It is in a state of being shielded by a part of. For this reason, since the entry of air into the beverage bottle-shaped can 1 is suppressed,
Due to the negative pressure effect, the inner solution is prevented from being discharged at once, and the amount poured out from the beverage bottle can 1 can be suppressed.

Therefore, according to this structure, even when the beverage bottle-shaped can 1 is largely tilted, the amount poured out from the beverage bottle-shaped can 1 can be suppressed, so that the beverage bottle-shaped can 1 is It is possible to improve the ease of drinking and pouring of the content liquid.

Further, in the case of a PET bottle made of a resin in which the inner wall of the mouth portion is a smooth straight surface, in the case of the bottle type can 1 for beverage, the inner wall 5 of the mouth portion 4 is made into an uneven shape by screwing. Since it is a surface, it is easy to suppress the flow after the inner solution in the beverage bottle can 1 collides with the inner wall 5 of the mouth 4. Further, since the curl portion 10 of the drinking spout 9 is configured to enter the inside of the drinking spout 9 in the radial direction, the curl portion 10 makes it easier to suppress the flow of the inner solution. There is. Therefore, it is possible to further promote the suppression of the amount poured out from the beverage bottle-shaped can 1.

As a comparative example to the above configuration, FIG.
The beverage bottle type can 11 shown in FIG. That is,
The beverage bottle-shaped can 11 shown in FIG. 3 has an outer diameter 17 of 38 m.
m, mouth inner diameter 16 is 30 mm, mouth height 18 is 30 mm,
The shape of the gentle shoulder portion 13 is formed into a bottomed cylindrical shape having a curved surface with a radius of 50 mm, and the diameter of the side wall 12 thereof is set to 66 mm.

Further, this beverage bottle type can 11 has a drinking mouth 19 in the direction of the mouth portion 14 of the inner tangent line C3 of the shape of the final shoulder portion 13 from the gentle shoulder portion 13 to the mouth portion 14.
More toward the outside of the beverage bottle-shaped can 11. Specifically, the inner tangent line C3 to the bottom surface of the beverage bottle type can 11
Is tilted at a position on the mouthpiece 19. That is, when the inner tangent line C3 is extended upward in the drawing, this extended portion intersects the central portion of the drinking spout 19.

For this reason, when the beverage bottle-shaped can 11 is tilted largely and poured into a container such as a cup at a stretch, or when the drinking bottle-shaped can 11 has a mouth opening 19 and is directly drunk, it is discharged. Since the content liquid does not collide with the inner wall of the mouth portion, the liquid is discharged all at once. As a result, there is a large amount of water flowing out from the drinking mouth 19, so that it overflows from the mouth, and it is necessary to take care not to drink at a large tilt. Therefore, when the beverage bottle-shaped can 11 is greatly tilted, and the drinking mouth 19 is put into the mouth and the drink is taken directly, a large amount flows out from the drinking mouth 19,
It will be difficult to drink.

Next, a second example of the embodiment of the present invention will be described. That is, as Example 2 of the embodiment of the present invention, a beverage bottle-shaped can 2 in which the shoulder portion 23 is an inclined surface as shown in FIG.
1 and the shoulder 33 as shown in FIG.
There is a beverage bottle-shaped can 31 having a shape narrowed inward just before reaching. Partial enlarged views of the shape from the shoulder to the mouth of FIGS. 4 and 5 are shown in FIGS. 6 and 7, respectively. The relationship between the shape from the shoulder to the mouth and the inner tangent line is shown below with reference to FIGS. 6 and 7.

First, the inner tangent line A shown in FIG. 4 is shown in detail in FIG. In FIG. 6, a bottle type can 2 for beverages
The portion from the shoulder portion 23 to the mouth portion 24 of No. 1 is shown in an enlarged manner. In FIG. 4, the shoulder portion 23 and the mouth portion 24, which form an inclined surface for narrowing the mouth portion 24 from the cylindrical side wall 22 of the beverage bottle-shaped can 21 to the diameter, have a predetermined radius of curvature (R
It is shown that they are connected smoothly based on 5). In FIG. 4, the inner tangent line A is a shoulder portion 23 which is a linear inclined surface.
And extends in the direction of the spout 29.
In the present embodiment, the inner tangent line A determines the inclination of the inner tangent line A depending on the shape of the shoulder portion 23, that is, the inclination of the shoulder portion 23. As a result, the inclination of the inner tangent line A with respect to the bottom surface of the beverage bottle can 21 intersects with the center line L of the beverage bottle can 21 in the mouth portion 24 and comes to the position of the end portion of the drinking mouth 24. That is, when the inner tangent line A is extended upward in the figure, the extended portion contacts the outer edge portion of the drinking spout 29 without intersecting the central portion of the drinking spout 29.

The inner tangent line B shown in FIG. 5 is shown in detail in FIG. In FIG. 7, a bottle type can 3 for beverages
The shape is shown in which the inner side of the inclined surface is narrowed just before reaching the mouth portion 34 from the shoulder portion 33 having the inclined surface for narrowing the mouth portion 34 to the diameter from the cylindrical side wall 32 of No. 1. In Figure 7,
The inclined surface 33a on the verge of reaching from the shoulder portion 33 to the mouth portion 34 is an arc drawn with a predetermined radius of curvature (R3) from the inside of the beverage bottle-shaped can 31, and a predetermined radius of curvature from outside the beverage bottle-shaped can 31. An inscribed line B is a straight line extending along the intersection with the arc drawn by (R4).
The inclination of this inscribed line B is the radius of curvature (R3, R
It will be determined by the size of 4) and the intersecting position.

In Example 2 which is the present embodiment, the inner tangent line B of the final shape of the shoulder 33 narrowed inward from the shoulder 33 to the mouth 34 as shown in FIG. 5 extends toward the mouth 34. It will be. As a result, the inclination of the inscribed line B with respect to the bottom surface of the beverage bottle-shaped can 31 intersects with the center line L of the beverage bottle-shaped can 31 in the mouth portion 34 and comes to the position of the end portion of the drinking mouth 39. That is, when the inner tangent line B is extended upward in the figure, the extended portion does not intersect with the central portion of the drinking spout 39 and contacts the outer edge portion of the drinking spout 39.

Thus, these beverage bottle-shaped cans 2
1 and 31 are inscribed lines A and B in the shape of the final shoulders 23 and 33a from the shoulders 23 and 33 to the mouths 24 and 34, respectively.
In the directions of 4 and 34, they are directed to the inside of the beverage bottle-shaped cans 21, 31 from the drinking ports 29, 39, that is, the inscribed lines A, B with respect to the bottom surfaces of the beverage bottle-shaped cans 21, 31.
Is tilted at a position lower than the positions of the spouts 24, 34. Therefore, when the beverage bottle-shaped cans 21 and 31 are tilted largely and poured into a container such as a cup at a stretch, or when the beverage bottle-shaped cans 21 and 31 are directly attached to the drinking ports 29 and 39, they are discharged. Since the content liquid collides with the inner walls 25 and 35 of the mouth and the phenomenon occurs all around the mouth, the inside of the bottle cans 21 and 31 for beverage and the outside of the bottle cans 21 and 31 for beverage are shielded. As a result, the invasion of air into the beverage bottle cans 21 and 31 is suppressed, the content liquid can be prevented from being discharged at once due to the negative pressure effect, and the amount of pouring can be suppressed.

Next, a third example of the embodiment of the present invention will be described. That is, as Example 3 which is an embodiment of the present invention,
The beverage bottle-shaped can 41 shown in FIG.
The inner diameter 46 of the mouth portion is 20 mm, the height 48 of the mouth portion is 30 mm, the shape of the gentle shoulder portion 43 is a curved bottomed cylindrical side wall 42 with a radius of 50 mm, and the diameter is 66 mm. In this case, in the direction of the mouth portion 44 of the inner tangent line C1 of the final shoulder portion 43 shape from the gentle shoulder portion 43 to the mouth portion 44, the mouth portion outside diameter 7 in FIG. It faces the inside of the bottle-shaped can 41 for a large amount. That is, the inclination of the inner tangent line C1 with respect to the bottom surface of the beverage bottle type can 41 is lower than the position of the drinking port 49. That is, when the inner tangent line C1 is extended upward in the drawing, the extended portion does not intersect with the drinking spout 49, and can be detached from the outer edge portion of the drinking spout 49.

For this reason, when the beverage bottle-shaped can 41 is tilted largely and poured into a container such as a cup, or when the drinking port 49 of the beverage bottle-shaped can 41 is attached to the mouth and the drink is taken directly,
The content liquid to be discharged collides with the inner wall 45 of the mouth of the mouth 44 greatly, and since the phenomenon is likely to occur all around the mouth, the inside of the can and the outside of the can are easily shielded, so that the beverage can be used. Since the entry of air into the bottle-shaped can 41 is suppressed, it is possible to prevent the content liquid from being discharged at once due to the negative pressure effect, so that the effect of suppressing the amount of pouring out becomes significant. As a result, even if the beverage bottle-shaped can 41 is largely tilted, the amount poured out from the beverage bottle-shaped can 41 is adjusted appropriately, so that it is easy to drink and easy to pour.

In order to make it easier to pour the beverage bottle-shaped can 41, such as when pouring the liquid content of the beverage bottle-shaped can 41 into a container such as a cup at a stretch, the inner diameter of the mouth is generally increased. Is desired. In order to satisfy the demand, it is necessary to make the mouth diameter as large as possible, but according to the configuration of this specific example described above, for example, when the outer diameter of the mouth portion of the beverage bottle can 41 is 33 mm, It is possible to provide a bottle-shaped can whose mouth 49 easily fits in the mouth, is easy to drink, is easy to pour, and prevents the mouth from overflowing.

Here, the correspondence between the structure of the embodiment and the structure of the present invention will be described. The beverage bottle-shaped can 1 corresponds to the beverage bottle-shaped can of the present invention, and the side wall 2 is the side wall of the present invention. The shoulder portion 3 corresponds to the shoulder portion of the present invention, the mouth portion 4 corresponds to the mouth portion of the present invention, the mouth portion inner diameter 6 corresponds to the mouth portion diameter of the present invention, and the mouth portion height 8 Corresponds to the height of the mouth of the present invention, and the inner tangents A, B, C1, C2, C3 correspond to the inner tangents of the present invention.
