Description

The present invention relates to a bottle with a handle.

Conventionally, as shown in, for example, Patent Document 1 below, there has been known a bottle with a handle, in which the body of the bottle is provided with a recess that opens radially rearward and in the left-right direction, a handle is attached to the recess, the recess faces downward, has a ceiling surface against which the upper end of the handle abuts, a first connection surface that extends upward from the outer periphery of the ceiling surface and is connected to the outer periphery of the body, and a pair of left and right second connection surfaces that extend outward in the left-right direction from both left and right ends of the first connection surface and are connected to the outer periphery of the body.

Patent No. 3927893

However, in the conventional bottles with handles described above, when a large compressive load is applied in the vertical direction and the ceiling surface is pressed against the upper end of the handle, due to the recent trend toward thinner bottles, a circumferentially extending bend is easily formed on the first connecting surface, and there is a risk of buckling deformation.

The present invention provides a bottle with a handle that can suppress buckling deformation.

The present invention employs the following means to solve the above problems. That is, the bottle with handle of the present invention has a recess in the body of the bottle that is integrally open in the radial rear and left-right directions, a handle is attached to the recess, and the recess faces downward and has a ceiling surface against which the upper end of the handle abuts, a first connection surface that extends upward from the outer periphery of the ceiling surface and is connected to the outer periphery of the body, and a pair of left and right second connection surfaces that extend outward in the left-right direction from both left and right ends of the first connection surface and are connected to the outer periphery of the body, and a first reinforcing rib extending in the up-down direction is formed on the second connection surface.

The first reinforcing rib is formed on the second connection surface, which increases the rigidity of the second connection surface. Even if a large compressive load is applied in the vertical direction and the ceiling surface is pressed strongly against the upper end of the handle, it is possible to prevent the formation of a circumferentially extending bend on the first connection surface, thereby suppressing buckling deformation of the bottle.

The first reinforcing rib may extend upward beyond the second connection surface and reach the outer circumferential surface of the body.

The first reinforcing rib extends above the second connection surface and reaches the outer peripheral surface of the body, which increases the rigidity of the portion of the body that is connected to the upper edge of the second connection surface, effectively increasing the rigidity of the second connection surface.

In the first connection surface, second reinforcing ribs extending in the vertical direction may be formed separately on both sides of the bottle axis extending in the vertical direction when viewed from the rear.

When viewed from the rear, second reinforcing ribs are formed separately on both sides of the first connection surface that sandwich the bottle axis in the left-right direction. Even if a large load is generated on the second connection surface when a large compressive load is applied in the vertical direction, the second reinforcing ribs can prevent this load from propagating circumferentially around the first connection surface, thereby suppressing buckling deformation of the bottle.

The second reinforcing rib may extend upward beyond the first connection surface and reach the outer circumferential surface of the body.

The second reinforcing rib extends upward beyond the first connection surface and reaches the outer peripheral surface of the body, increasing the rigidity of the portion of the body that is connected to the upper edge of the first connection surface. When a large compressive load is applied in the vertical direction, the large load generated on the second connection surface can be reliably prevented from propagating in the circumferential direction around the first connection surface.

The first connection surface, in a cross section perpendicular to the bottle axis, has a trapezoidal shape having an upper base located at the rear end and a pair of legs extending from both left and right ends of the upper base in a direction that separates them in the left and right direction as they move forward, and a third reinforcing rib extending in the up and down direction is formed separately on each of the pair of legs of the first connection surface that correspond to the legs, and the third reinforcing rib is located between the first reinforcing rib and the second reinforcing rib, and the pair of left and right third reinforcing ribs may extend in a direction that approaches each other in the circumferential direction as they move from top to bottom.

Since a third reinforcing rib is formed on the first connection surface, even if a large load is generated on the second connection surface when a large compressive load is applied in the vertical direction, the load can be reliably prevented from propagating circumferentially around the first connection surface.
Since the pair of left and right third reinforcing ribs extend circumferentially toward each other as they move from top to bottom, the third reinforcing ribs can be easily formed on the leg portion of the first connecting surface, and forming the third reinforcing ribs can prevent stress from concentrating on the leg portion.

The third reinforcing rib may extend upward beyond the first connection surface and reach the outer circumferential surface of the body.

The third reinforcing rib extends upward beyond the first connection surface and reaches the outer peripheral surface of the body, increasing the rigidity of the portion of the body that is connected to the upper edge of the first connection surface. This reliably prevents the large load generated on the second connection surface from propagating circumferentially around the first connection surface when a large compressive load is applied in the vertical direction.

This invention makes it possible to suppress buckling deformation.

FIG. 1 is a side view of a handle-equipped bottle shown as one embodiment of the present invention, viewed from the rear. FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1.

Hereinafter, one embodiment of a bottle with a handle 1 will be described with reference to the drawings.
1 and 2, the bottle with handle 1 includes a bottle 10 and a handle 11. The internal volume of the bottle 10 is, for example, 1 liter or more.
The bottle 10 comprises a mouth portion 12, a shoulder portion 13, a body portion 14 and a bottom portion 15, and these portions 12 to 15 are connected in this order with their respective central axes positioned on a common axis.

Hereinafter, the common axis is referred to as the bottle axis O, the mouth 12 side along the bottle axis O is referred to as the upper side, and the bottom 15 side is referred to as the lower side, the direction along the bottle axis O is referred to as the up-down direction, and the direction intersecting the bottle axis O when viewed from the up-down direction is referred to as the radial direction. In addition, within the radial direction, the side on which the handle 11 is provided with respect to the bottle axis O is referred to as the rear side, the opposite side of the handle 11 that sandwiches the bottle axis O in the radial direction is referred to as the front side, and the direction perpendicular to the front-rear direction when viewed from the up-down direction is referred to as the left-right direction.

In the illustrated example, the mouth 12, shoulder 13, body 14, and bottom 15 each have a circular cross-sectional shape perpendicular to the bottle axis O. The handle 11 is formed in an annular shape that opens in the left and right directions.

A circumferential groove 14a is formed at the upper end of the body 14, which extends continuously over the entire circumferential length. The body 14 is provided with a recess 16 that opens integrally in the rear and left-right directions. The recess 16 is provided at the upper part of the body 14. The recess 16 is located below the circumferential groove 14a. The left-right center of the recess 16 is located at the left-right center of the outer circumferential surface of the body 14 that faces rearward. The recess 16 is defined by a ceiling surface 16a located at the upper end and facing downward, a lower surface 16b located at the lower end and facing upward, and a bottom surface 16c that connects the front ends of the ceiling surface 16a and the lower surface 16b and faces rearward. A handle 11 is attached to the recess 16. The front end of the handle 11 is recessed into the bottom surface 16c, the upper end of the handle 11 abuts against the ceiling surface 16a, and the lower end of the handle abuts against the lower surface 16b.

The recess 16 has a first connection surface 21 that extends upward from the outer periphery of the ceiling surface 16a and is connected to the outer periphery of the body 14. As shown in FIG. 3, the first connection surface 21 has a trapezoidal shape in a cross section perpendicular to the bottle axis O, with an upper base located at the rear end and a pair of legs that extend from both left and right ends of the upper base in directions that move away from each other in the left and right direction as they move forward.

That is, the first connection surface 21 has a pair of leg portions 22 corresponding to the legs, and an upper base portion 23 corresponding to the upper base. The left-right center of the upper base portion 23 is located at the left-right center of the outer circumferential surface of the body 14 that faces rearward. In the cross-sectional view, the first connection surface 21 has a symmetrical shape with respect to a straight line passing through the left-right center of the body 14.

The pair of leg portions 22 extend away from each other in the left-right direction as they move upward from the outer periphery of the ceiling surface 16a. When viewed from the rear, the left-right length of the leg portions 22 increases from bottom to top.

The upper base portion 23 extends upward from the outer periphery of the ceiling surface 16a and then toward the rear. When viewed from the rear, the length of the upper base portion 23 in the left-right direction becomes slightly longer from the bottom to the top. The upper base portion 23 faces the rear end of the handle 11 in the up-down direction.
Auxiliary ribs 26 are formed on the upper base portion 23. The auxiliary ribs 26 are formed in stripes extending in the left-right direction. The auxiliary ribs 26 are grooves. A plurality of auxiliary ribs 26 are formed on the upper base portion 23 at intervals in the up-down direction.

The recess 16 has a pair of second connection surfaces 25 that extend outward in the left-right direction from both left-right ends of the first connection surface 21 and are connected to the outer circumferential surface of the body 14. As shown in FIG. 3, the second connection surfaces 25 are curved in a convex shape toward the rear in a cross section perpendicular to the bottle axis O. The second connection surfaces 25 are connected without any steps to both left-right ends of the first connection surface 21. The connection portion 16d between the second connection surface 25 and the first connection surface 21 is curved in a concave shape that is recessed toward the front in the cross section. The second connection surface 25 is located outward in the left-right direction from the handle 11.

1 and 2, a first reinforcing rib 31 extending in the vertical direction is formed on the second connection surface 25. The first reinforcing rib 31 is provided at the connection portion of the second connection surface 25 with the first connection surface 21. The first reinforcing rib 31 is formed in a strip extending in the vertical direction. When viewed from the left and right direction, the first reinforcing rib 31 extends rearward from the bottom to the top. The first reinforcing rib 31 may extend straight in the vertical direction. The first reinforcing rib 31 is a groove. The first reinforcing rib 31 extends upward beyond the second connection surface 25 and reaches the outer peripheral surface of the body 14. The upper end of the first reinforcing rib 31 is connected to or close to the lower end of the circumferential groove 14a.

When viewed from the rear, the first connection surface 21 has second reinforcing ribs 32 extending in the vertical direction formed separately on both sides of the bottle axis O. The second reinforcing ribs 32 are formed in stripes extending in the vertical direction. The second reinforcing ribs 32 are grooves. The second reinforcing ribs 32 extend upward beyond the first connection surface 21 and reach the outer peripheral surface of the body 14. The upper end of the second reinforcing rib 32 is connected to or adjacent to the lower end of the circumferential groove 14a. When viewed from the rear, the second reinforcing rib 32 faces the handle 11 in the vertical direction.

A third reinforcing rib 33 extending in the vertical direction is formed separately on each portion of the first connection surface 21 located between the first reinforcing rib 31 and the second reinforcing rib 32. The third reinforcing rib 33 is formed in a stripe shape extending in the vertical direction. The third reinforcing rib 33 is a groove. The third reinforcing rib 33 extends upward beyond the first connection surface 21 and reaches the outer peripheral surface of the body 14. The upper end of the third reinforcing rib 33 is connected to or adjacent to the lower end of the circumferential groove 14a. The third reinforcing rib 33 is located outboard of the handle 11 in the left-right direction.

The inclination angle of the third reinforcing rib 33 in the vertical direction is greater than the inclination angles of the first reinforcing rib 31 and the second reinforcing rib 32 in the vertical direction. The pair of left and right third reinforcing ribs 33 extend in a circumferential direction approaching each other as they move from top to bottom. The second reinforcing rib 32 and the third reinforcing rib 33 are provided on the leg portion 22 of the first connecting surface 21. The second reinforcing rib 32 is provided on the connecting portion of the leg portion 22 with the upper base portion 23. The second reinforcing rib 32 and the third reinforcing rib 33 may be provided on the upper base portion 23 of the first connecting surface 21.

The lower end of each of the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 is located above the lower end of the auxiliary rib 26 that is located at the lowest among the multiple auxiliary ribs 26. The lengths of the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 are all equal to each other. The widths of the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 are all equal to each other.

As described above, in the bottle with handle 1 according to this embodiment, the first reinforcing rib 31 is formed on the second connection surface 25, which increases the rigidity of the second connection surface 25. Even if a large compressive load is applied in the vertical direction and the ceiling surface 16a is pressed strongly against the upper end of the handle 11, it is possible to prevent the first connection surface 21 from forming a circumferentially extending bend, thereby suppressing buckling deformation of the bottle 10.

The first reinforcing rib 31 extends above the second connection surface 25 and reaches the outer peripheral surface of the body 14, which increases the rigidity of the portion of the body 14 that is connected to the upper edge of the second connection surface 25, thereby effectively increasing the rigidity of the second connection surface 25.

When viewed from the rear, the first connection surface 21 has second reinforcing ribs 32 formed on both sides of the bottle axis O in the left-right direction. Even if a large load is generated on the second connection surface 25 when a large compressive load is applied in the vertical direction, the second reinforcing ribs 32 can prevent this load from propagating in the circumferential direction around the first connection surface 21, thereby suppressing buckling deformation of the bottle 10.

The second reinforcing rib 32 extends upward beyond the first connection surface 21 and reaches the outer peripheral surface of the body 14, increasing the rigidity of the portion of the body 14 that is connected to the upper edge of the first connection surface 21. This reliably prevents the large load generated on the second connection surface 25 from propagating circumferentially around the first connection surface 21 when a large compressive load is applied in the vertical direction.

Since a third reinforcing rib 33 is formed on the first connection surface 21, even if a large load is generated on the second connection surface 25 when a large compressive load is applied in the vertical direction, this load can be reliably prevented from propagating circumferentially around the first connection surface 21.
Since the pair of left and right third reinforcing ribs 33 extend circumferentially toward each other as they move from top to bottom, the third reinforcing ribs 33 can be easily formed on the leg portions 22 of the first connecting surface 21, and the formation of the third reinforcing ribs 33 can prevent stress from concentrating in the leg portions 22.

The third reinforcing rib 33 extends upward beyond the first connection surface 21 and reaches the outer peripheral surface of the body 14, increasing the rigidity of the portion of the body 14 that is connected to the upper edge of the first connection surface 21. This reliably prevents the large load generated on the second connection surface 25 from propagating circumferentially around the first connection surface 21 when a large compressive load is applied in the vertical direction.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 may be protrusions.
The upper ends of the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 may be spaced downward from the circumferential groove 14a.
The first reinforcing rib 31 may be provided only on the second connecting surface 25 .
The second reinforcing rib 32 and the third reinforcing rib 33 may be provided only on the first connecting surface 21 .
The inclination angle of the third reinforcing rib 33 in the up-down direction may be set to be equal to or smaller than the inclination angles of the first reinforcing rib 31 and the second reinforcing rib 32 in the up-down direction, respectively.
The pair of left and right third reinforcing ribs 33 may extend in directions away from each other in the circumferential direction as they go from top to bottom, or may extend straight in the up-down direction.
The second reinforcing rib 32 and the third reinforcing rib 33 do not necessarily have to be provided.
The leg portion 22 and the upper base portion 23 may extend straight upward from the outer periphery of the ceiling surface 16a.

In addition, the components in the above embodiments may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above embodiments and variations may be combined as appropriate.
