[Prior art]

  As a drink bottle used by being attached to a water supply device, for example, the one shown in FIG. 7 is known. Has been. This plastic bottle C has a mouth portion 21, a shoulder portion 22, and a cylindrical body portion 2. 3, bottom 24, handle 25, the boundary between the shoulder 22 and the body 23, the middle of the body 23 At the boundary between the bottom portion 24 and the body portion 23 and the bottom portion 24, respectively 7, 28 are provided.   This bottle has a capacity of about 19 liters and is used by mounting it on a water dispenser in a fallen state. However, when the amount of water in the interior decreases due to use, the internal space temporarily becomes negative pressure and The tor may deform so as to project inward. Keep the bottle exposed on the water dispenser. It is said that the deformation damages the appearance and requires repair for reuse. There is a problem.

[0003]

[Problems to be solved by the device]

  The present invention aims to solve the above problems, and is provided above and below the body. By providing multiple small ribs on the ring-shaped rib, A plastic bottle for mounting a water supply that reinforces against and does not deform when used The purpose is to provide.

[0004]

[Means for Solving the Problems]

  In order to solve the above-mentioned problems, the present invention provides a bottle, a mouth portion, a shoulder portion, and a body portion. A plastic bottle having a bottom, the boundary between the shoulder and the body and the body A large convex rib is provided over the entire circumference at the boundary with the bottom and the entire circumference is located on this large convex rib. A configuration is adopted in which a plurality of small convex ribs are provided.

[0005]

[Embodiment of device]

  Next, an embodiment of the present invention will be described with reference to the drawings. Figure 1 of the bottle Front view, FIG. 2 is a side view of the bottle, FIG. 3 is an enlarged sectional view of a part of the bottle, and FIG. 4 is a mouth part. 5 is an enlarged cross-sectional view of a part of the mouth portion.

[0006]   1 and 2, A is a plastic molded by stretch blow and having a capacity of about 19 l. The stick bottle is composed of a mouth portion 1, a shoulder portion 2, a body portion 3 and a bottom portion 4. Bo The tortu A is set on the water dispenser in a state of being turned upside down. At the top of the mouth 1, An annular protrusion 6 that surrounds the opening 5 and protrudes upward is formed. Shoulder 2 is mouth It extends downward from the lower end of 1 in a funnel shape and is connected to the upper end of the body 3. The whole body 3 Is substantially cylindrical, and has a handle portion 7 at a part in the vertical direction.

[0007]   The boundary between the shoulder 2 and the body 3, the vertical center of the body 3, and the boundary between the shoulder 2 and the bottom 4. Has large convex ribs 8, 9 and 10 all around. Large convex ribs 8, 9, 10 are Has rounded rising parts 8a, 8b, 9a, 9b, 10a, 10b In the middle, cylindrical parts 8c, 9c, 10c are provided.

[0008]   On the cylindrical portions 8c and 10c of the upper convex rib 8 on the upper side and the large convex rib 10 on the lower side, Three small convex ribs 11 and 12 are formed at equal intervals in the same direction, all over the circumference. Has been done.

[0009]   The bottle of this embodiment has a capacity of about 19 liters and extends from the bottom end wall to the top of the barrel. Up to about 370mm, outer diameter of the body is about 270mm, large convex ribs 8,9 , 10 has a width of 30 to 45 mm. The present invention is of course limited to this size Not of.

[0010]   FIG. 6 shows an embodiment of bottle B with a capacity of about 11 l. Basic structure is the above embodiment Since it is the same as that of the embodiment, the same reference numerals are given to the same components and the description will be omitted. This The bottle B of this embodiment does not have a rib in the middle of the body 3. Large convex ribs 8 and 10 There are two small convex ribs 11 and 12, respectively. The height from the bottom end wall to the upper end of the trunk is It is about 211 mm, the outer diameter of the body is about 270 mm, and the widths of the large convex ribs 8 and 30 are 30 mm. It is up to 45 mm and can be used by mounting it on the same water dispenser as the bottle A of the previous embodiment. Wear.

[0011]

[Effect of the Invention] Since the present invention is configured as described above, it has the following effects. . Large convex over the entire circumference at the boundary between the shoulder and the trunk and at the boundary between the trunk and the bottom In addition to the ribs, were there a plurality of small convex ribs all around the large convex rib? The large convex ribs are reinforced by the small convex ribs. The addition of small convex ribs on large convex ribs Since it is a very small form change, it is equivalent to the old bottle, such as compatibility with a water supply device. It can be handled without requiring any changes. Two large convex ribs as a whole The side of the bottle can be supported at two points, preventing deformation due to negative pressure during use. can do.   Since an annular ridge protruding upward is formed at the upper end of the mouth, the ridge is Part of the cap fits into the flexible underside of the cap and seals the mouth. Water leakage from the pump can be prevented.
