Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional bottle with a handle, when a large compressive load is applied in the vertical direction and the ceiling surface is pressed against the upper end portion of the handle, with the recent thinning, a bending curve extending in the circumferential direction is likely to occur in the first connection surface, and there is a risk of buckling deformation.

[0005] The present invention provides a bottle with a handle that can suppress buckling deformation.

Means for Solving the Problems

[0006] To solve the above problems, the present invention employs the following means. Specifically, the bottle with a handle of the present invention has a recess in the body of the bottle that is integrally open in the rearward and left-right directions in the radial direction, and a handle is attached to the recess. The recess has a ceiling surface facing downward and against which the upper end of the handle abuts, a first connecting surface extending upward from the outer peripheral edge of the ceiling surface and connected to the outer peripheral surface of the body, and a pair of left and right second connecting surfaces extending outward in the left-right direction from both ends of the first connecting surface and connected to the outer peripheral surface of the body, and a first reinforcing rib extending in the vertical direction is formed on the second connecting surfaces.

[0007] Since the first reinforcing rib is formed on the second connecting surface, the rigidity of the second connecting surface is increased. This makes it possible to suppress the formation of circumferentially extending fold lines on the first connecting surface even when a large compressive load is applied in the vertical direction and the ceiling surface is strongly pressed against the upper end of the handle, thereby suppressing buckling deformation of the bottle.

[0008] The first reinforcing rib may extend above the second connecting surface and reach the outer circumferential surface of the body.

[0009] Since the first reinforcing rib extends above the second connecting surface and reaches the outer circumferential surface of the body, the rigidity of the portion of the body connected to the upper edge of the second connecting surface is increased, thereby effectively increasing the rigidity of the second connecting surface.

[0010] On the first connecting surface, when viewed from the rear, second reinforcing ribs extending in the vertical direction may be separately formed on both sides of the bottle shaft that extends in the vertical direction, sandwiching it in the left-right direction.

[0011] In the first connection surface, when viewed from the rear, second reinforcing ribs are individually formed on both sides of the bottle shaft in the left-right direction. Therefore, even if a large compressive load is applied in the vertical direction and a large load is generated on the second connection surface, the second reinforcing ribs can prevent this load from propagating circumferentially across the first connection surface, thereby suppressing buckling deformation of the bottle.

[0012] The second reinforcing rib may extend above the first connecting surface and reach the outer circumferential surface of the body.

[0013] Since the second reinforcing rib extends above the first connecting surface and reaches the outer circumferential surface of the body, the rigidity of the portion of the body connected to the upper edge of the first connecting surface is increased. This ensures that when a large compressive load is applied in the vertical direction, the large load generated on the second connecting surface is not transmitted circumferentially across the first connecting surface.

[0014] The first connecting surface has a trapezoidal shape in a cross-sectional view perpendicular to the bottle axis, with an upper base located at the rear end and a pair of legs extending from both ends of the upper base in the left-right direction toward the front, moving away from each other in the left-right direction. A third reinforcing rib extending in the vertical direction is formed separately on the pair of leg portions of the first connecting surface corresponding to the legs, and the third reinforcing rib is located between the first reinforcing rib and the second reinforcing rib. The left and right pair of third reinforcing ribs may extend toward each other in the circumferential direction toward each other toward the front.

[0015] Since a third reinforcing rib is formed on the first connecting surface, even if a large load is generated on the second connecting surface when a large compressive load is applied in the vertical direction, it is possible to reliably prevent this load from propagating circumferentially across the first connecting surface. Since the pair of third reinforcing ribs on the left and right extend in a direction that brings them closer to each other in the circumferential direction 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 the concentration of stress on the leg portion that would otherwise occur due to the formation of the third reinforcing ribs can be suppressed.

[0016] The third reinforcing rib may extend above the first connecting surface and reach the outer circumferential surface of the body.

[0017] Since the third reinforcing rib reaches the outer peripheral surface of the body part beyond the first connection surface upward, the rigidity of the part of the body part that continues to the upper end edge of the first connection surface is enhanced. When a large compressive load is applied in the vertical direction, it is possible to reliably suppress the large load generated on the second connection surface from propagating in the circumferential direction to the first connection surface.

[Figure 3] It is a cross - sectional view taken along the arrow III - III in FIG. 1.

Modes for Carrying Out the Invention

[0020] Hereinafter, with reference to the drawings, one embodiment of the bottle 1 with a handle will be described. As shown in FIGS. 1 and 2, the bottle 1 with a handle 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 includes a mouth part 12, a shoulder part 13, a body part 14, and a bottom part 15. These 12 - 15 are arranged in this order with their respective central axes located on a common axis.

[0021] Hereinafter, the common axis is referred to as the bottle axis O. The mouth portion 12 side is the upper side and the bottom portion 15 side is the lower side along the bottle axis O. The direction along the bottle axis O is the vertical direction. When viewed from the vertical direction, the direction intersecting the bottle axis O is the radial direction. Also, among the radial directions, the side where the handle 11 is provided with respect to the bottle axis O is the rear side, the opposite side of the handle 11 sandwiching the bottle axis O in the radial direction is the front side, and when viewed from the vertical direction, the direction orthogonal to the front-rear direction is the left-right direction.

[0022] In the illustrated example, the mouth portion 12, the shoulder portion 13, the body portion 14, and the bottom portion 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-right direction.

[0023] A circumferential groove 14a that continuously extends over the entire circumferential length is formed at the upper end portion of the body portion 14. A recess 16 that opens integrally in the rearward and left-right directions is provided in the body portion 14. The recess 16 is provided at the upper portion of the body portion 14. The recess 16 is located below the circumferential groove 14a. The central portion in the left-right direction of the recess 16 is located at the central portion in the left-right direction of the portion of the outer peripheral surface of the body portion 14 that faces the rear. The recess 16 is defined by a ceiling surface 16a that is located at the upper end and faces downward, a lower surface 16b that is located at the lower end and faces upward, and a bottom surface 16c that connects the front end portions of the ceiling surface 16a and the lower surface 16b and faces the rear. The handle 11 is attached to the recess 16. The front end portion of the handle 11 is recessed into the bottom surface 16c, the upper end portion of the handle 11 abuts against the ceiling surface 16a, and the lower end portion of the handle abuts against the lower surface 16b.

[0024] The recess 16 includes a first connection surface 21 that extends upward from the outer peripheral edge of the ceiling surface 16a and is connected to the outer peripheral surface of the body portion 14. As shown in FIG. 3, the first connection surface 21 has a trapezoidal shape in a cross-sectional view perpendicular to the bottle axis O, having an upper base located at the rear end and a pair of legs that extend in a direction in which they separate from each other in the left-right direction as they go forward from both ends in the left-right direction of the upper base.

[0025] In other words, the first connecting surface 21 comprises a pair of leg portions 22 corresponding to the legs and an upper base portion 23 corresponding to the upper base. The left-right central portion of the upper base portion 23 is located in the left-right central portion of the outer circumferential surface of the body portion 14 that faces rearward. In the cross-sectional view, the first connecting surface 21 exhibits a symmetrical shape with respect to a line passing through the left-right central portion of the body portion 14.

[0026] The pair of leg portions 22 extend upward from the outer edge of the ceiling surface 16a, moving away from each other in the left-right direction. When viewed from the rear, the length of the leg portions 22 in the left-right direction increases from the bottom to the top.

[0027] The upper base portion 23 extends towards the rear as it moves upward from the outer edge of the ceiling surface 16a. When viewed from the rear, the length of the upper base portion 23 in the left-right direction is slightly longer as it moves from bottom to top. The upper base portion 23 is opposite the rear end of the handle 11 in the vertical direction. Auxiliary ribs 26 are formed on the upper base portion 23. The auxiliary ribs 26 are formed in a strip-like shape extending in the left-right direction. The auxiliary ribs 26 are grooves. Multiple auxiliary ribs 26 are formed on the upper base portion 23 at intervals in the vertical direction.

[0028] The recess 16 extends outward in the left-right direction from both ends of the first connecting surface 21 and is provided with a pair of left and right second connecting surfaces 25 that are connected to the outer circumferential surface of the body 14. As shown in Figure 3, the second connecting surfaces 25 have a curved shape that protrudes towards the rear in a cross-sectional view perpendicular to the bottle axis O. The second connecting surfaces 25 are seamlessly connected to both ends of the first connecting surface 21 in the left-right direction. The connection portion 16d between the second connecting surface 25 and the first connecting surface 21 has a concave curved shape that is recessed towards the front in the aforementioned cross-sectional view. The second connecting surfaces 25 are located outward in the left-right direction from the handle 11.

[0029] As shown in Figures 1 and 2, a first reinforcing rib 31 extending in the vertical direction is formed on the second connecting surface 25. The first reinforcing rib 31 is provided at the connection portion between the second connecting surface 25 and the first connecting surface 21. The first reinforcing rib 31 is formed in a strip shape extending in the vertical direction. When viewed from the left and right directions, the first reinforcing rib 31 extends towards the rear as it goes from bottom to top. The first reinforcing rib 31 may also extend straight in the vertical direction. The first reinforcing rib 31 is a groove. The first reinforcing rib 31 extends above the second connecting surface 25 and reaches the outer circumferential surface of the body portion 14. The upper end of the first reinforcing rib 31 is connected to or close to the lower end of the circumferential groove 14a.

[0030] On the first connecting surface 21, when viewed from the rear, second reinforcing ribs 32 extending in the vertical direction are separately formed on both sides of the bottle shaft O in the left-right direction. The second reinforcing ribs 32 are formed in a strip shape extending in the vertical direction. The second reinforcing ribs 32 are grooves. The second reinforcing ribs 32 extend above the first connecting surface 21 and reach the outer circumferential surface of the body portion 14. The upper end of the second reinforcing rib 32 is connected to or close 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.

[0031] On the first connecting surface 21, a third reinforcing rib 33 extending in the vertical direction is individually formed in each portion located between the first reinforcing rib 31 and the second reinforcing rib 32. The third reinforcing rib 33 is formed in a strip-like shape extending in the vertical direction. The third reinforcing rib 33 is a groove. The third reinforcing rib 33 extends above the first connecting surface 21 and reaches the outer circumferential surface of the body portion 14. The upper end of the third reinforcing rib 33 is connected to or close to the lower end of the circumferential groove 14a. The third reinforcing rib 33 is located outside the handle 11 in the left-right direction.

[0032] The inclination angle of the third reinforcing rib 33 with respect to the vertical direction is greater than the respective inclination angles of the first reinforcing rib 31 and the second reinforcing rib 32 with respect to the vertical direction. The pair of left and right third reinforcing ribs 33 extend in a direction that approaches each other in the circumferential direction 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 at the connection portion between the leg portion 22 and the upper base portion 23. Alternatively, 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.

[0033] The lower ends of the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 are located above the lower end of the lowest auxiliary rib 26 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 equal to each other. The widths of the first reinforcing rib 31, the second reinforcing rib 32, and the third reinforcing rib 33 are equal to each other.

[0034] As described above, in the bottle 1 with a handle according to this embodiment, since the first reinforcing rib 31 is formed on the second connecting surface 25, the rigidity of the second connecting surface 25 is increased. Even when a large compressive load is applied in the vertical direction and the top surface 16a is strongly pressed against the upper end of the handle 11, it is possible to suppress the formation of a circumferentially extending fold line on the first connecting surface 21, thereby suppressing buckling deformation of the bottle 10.

[0035] Since the first reinforcing rib 31 extends above the second connecting surface 25 and reaches the outer circumferential surface of the body portion 14, the rigidity of the portion of the body portion 14 that is connected to the upper edge of the second connecting surface 25 is increased, thereby effectively increasing the rigidity of the second connecting surface 25.

[0036] In the first connection surface 21, when viewed from the rear, second reinforcing ribs 32 are individually formed on both sides of the bottle axis O in the left-right direction. Therefore, 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 circumferentially across the first connection surface 21, thereby suppressing buckling deformation of the bottle 10.

[0037] Since the second reinforcing rib 32 extends above the first connecting surface 21 and reaches the outer circumferential surface of the body portion 14, the rigidity of the portion of the body portion 14 connected to the upper edge of the first connecting surface 21 is increased. This ensures that when a large compressive load is applied in the vertical direction, the large load generated on the second connecting surface 25 does not propagate circumferentially across the first connecting surface 21.

[0038] Since the third reinforcing rib 33 is formed on the first connecting surface 21, even if a large load is generated on the second connecting surface 25 when a large compressive load is applied in the vertical direction, it is possible to reliably prevent this load from propagating circumferentially across the first connecting surface 21. Since the pair of left and right third reinforcing ribs 33 extend in a direction that brings them closer to each other in the circumferential direction as they move from top to bottom, the third reinforcing ribs 33 can be easily formed on the leg portion 22 of the first connecting surface 21, and the concentration of stress on the leg portion 22 caused by the formation of the third reinforcing ribs 33 can be suppressed.

[0039] Since the third reinforcing rib 33 extends above the first connecting surface 21 and reaches the outer circumferential surface of the body portion 14, the rigidity of the portion of the body portion 14 connected to the upper edge of the first connecting surface 21 is increased. This ensures that when a large compressive load is applied in the vertical direction, the large load generated on the second connecting surface 25 does not propagate circumferentially across the first connecting surface 21.

[0040] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0041] 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 set back 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 with respect to the vertical direction may be set to be less than or equal to the respective inclination angles of the first reinforcing rib 31 and the second reinforcing rib 32 with respect to the vertical direction. The pair of left and right third reinforcing ribs 33 may extend in a direction that separates them from each other in the circumferential direction as they move from top to bottom, or they may extend straight in the vertical direction. The second reinforcing rib 32 and the third reinforcing rib 33 do not need to be provided. The leg portion 22 and the upper base portion 23 may extend straight upward from the outer edge of the ceiling surface 16a.

[0042] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of symbols]
