Description

[Detailed explanation of the idea] This case concerns a bottle with a handle.

In recent years, thin-walled bottles made of saturated polyester resin and biaxially stretched have come into widespread use.

This type of bottle has the advantages of high mechanical strength, light weight, no leaching of harmful substances such as solvents during use, and no generation of harmful gas when incinerated, and is extremely suitable for forming large bottles. I feel well.

On the other hand, there are bottles made of other synthetic resins with integrally molded handles.

However, in the above biaxially stretched saturated polyester resin bottle, it is extremely difficult to integrally mold the handle in this way.

In view of this, the present project aims to provide a handle easily and strongly even in such biaxially stretched saturated polyester resin bottles, and to provide sufficient strength even for large bottles containing 1 liter or more without any problems in strength. It is something to do.

The illustrated embodiment will be described below.

In the figure, 1 is a large bottle body made of saturated polyester resin that is biaxially stretched, and 2 is a handle that is injection molded from a suitable synthetic resin.

The bottle main body 1 has an outward facing flange 12 at the lower end of the mouth and neck part 11, and below the outward facing flange 12, a stepped shoulder part 13 is formed with a diameter larger than that of the outward facing flange. It is well formed into a depression 15.

Further, a downward step portion 12a for engaging the handle is formed at the lower edge of the outward flange 12.

The handle 2 has a cylindrical portion 21 that fits between the outward flange 12 and the stepped shoulder portion 13, and an inverted-shaped grip portion 22 is integrally cantilevered from the back of the cylindrical portion 21. The lower half 21a of the cylindrical part 21 is formed into a straight cylinder that fits into the stepped shoulder part 13, and the upper half 21b is formed into a tapered cylinder with a concave upper part. A plurality of vertical grooves 23 are arranged at regular intervals, leaving an appropriate width, and the upper end thereof is engaged with the downward step 12a of the outward flange 12.

Further, on the back of the cylindrical portion 21, an upright wall 24 is integrally provided to protrude from the lower half 21a, and the grip portion 22 is integrally provided to protrude from the upright wall and the back of the lower cylindrical half 21a connected thereto, A plurality of vertical ribs 25 are integrally provided at appropriate intervals between the opposing surfaces of the upright wall 24 and the upper half of the cylindrical portion 21b, and the ribs 2
5 are made to abut against the outer circumferential surface of the outward flange 12, and the rib serves as an abutting portion A that rigidly transmits the tilting force from the grip portion 22 to the weir body 1.

Therefore, when attaching the handle 2 to the weir body 1, the handle 2
The gripping portion 22 is positioned in the recess 15 of the weir body 11, and the cylindrical portion 21 is pushed into the weir body from above.

In this way, the lower half 21a of the cylinder is aligned with the stepped shoulder 1 of the weir body 1.
3, the upper half 21b of the cylindrical portion passes over the outward flange 12 of the weir body 1, that is, the upper half 21b of the cylindrical portion
Since it has a plurality of grooves 23 and has bending elasticity as a material, it can be elastically bent, so it can overcome the outward flange 12 and engage with the downward step 12a, preventing it from coming out. be done.

Further, on the back side of the cylindrical portion 21, the plurality of ribs 25...therefore, the abutting portion A abuts against the outer periphery of the outward flange 12.

According to the present invention, in the weir body 1, an outward flange 12 is provided at the lower end of the mouth portion 11, and a stepped shoulder portion 13 having a larger diameter than the outward flange is formed below the outward flange 12.
The handle 2 is provided with a cylindrical part 21 whose upper and lower ends are fitted and engaged with the outward flange 12 and the stepped shoulder part 13,
The cylindrical portion 21 has a lower half 21a with a lower end located at the stepped shoulder portion 13.
The upper half 21b is formed into a tapered cylinder whose upper end engages with the lower surface of the stepped shoulder 13, and a plurality of upper half 21b are formed with an appropriate width left on the back. Since the vertical grooves 23 are arranged at equal intervals, the handle 2 of the weir body 1 can be attached by simply fitting the cylindrical part 21 from above. Due to the presence of the plurality of grooves 23, the upper half 21b of the part 21 is slightly but temporarily elastically deformed and overcomes the outward flange 12, and can be mounted extremely easily without the need for screwing or the like. , and if you get over it, the first half 2
The taper of 1b acts effectively, and the more the load is applied, the stronger the engagement with the outward flange 12 becomes, and the attachment can be ensured.

- Furthermore, in the weir body 1, a depression 15 is formed on the upper back of the body 14.
In the handle 2, an inverted-shaped grip portion 22 is integrally provided in a cantilevered manner and protrudes from the back of the cylindrical portion 21.
is located in the recess 15, and an abutting part A formed by a plurality of ribs 25, etc. 7 is provided on the upper edge of the base of the gripping part 22, and the abutting part A is placed on the back surface of the outward flange 12. Because they abut, the grip part 22 is easy to grip, and since it does not protrude outward, it does not get in the way, and the tilting force from the grip part 22 to the weir body 1 can be transmitted rigidly via the abutment part A. Even if the grip part 22 is cantilevered or the weir body is large, the handle can be firmly provided without any problem in terms of strength, and
Since the grip portion 22 is shaped like a cantilever, it can be used like a hook, which is convenient for use.

Therefore, even a saturated polyester resin bottle made of biaxially stretched resin can be easily provided with a handle.
It is useful in practical terms.
