Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a synthetic resin bottle with a handle.

"Prior Art" Conventionally, the handle of a synthetic resin bottle was integrally formed with the bottle body.

``Problems to be Solved by the Invention'' As in the conventional example described above, when the bottle body and handle are integrally formed, the mold becomes complicated and productivity decreases, resulting in high costs. In addition, in the case of thin-walled bottles with poor rigidity, such as biaxially stretched bottles, the handle attachment part lacks strength, making it impossible to form the handle integrally, and requiring ingenuity in the handle attachment structure. .

In the present invention, the bottle body and the handle are formed separately and the handle is attached to the mouth and neck of the bottle body by a simple means, so that a bottle with a handle can be formed easily and inexpensively, and the handle It is also designed to be easy to install.

"Means for Solving the Problems" A synthetic resin bottle with a handle according to the present invention includes a bottle body 1 having an outward flange 5 attached to the mouth and neck part 4;
A ring-shaped part 6 is fitted to the mouth and neck by engaging with the lower surface of the outward facing flange, and a rod-shaped handle 7 is integrally protruded from the front outer surface of the ring-shaped part in the front-down direction. It consists of a member with a handle 2,
The ring-shaped portion is formed to a size that allows the outward flange to pass through, and the rear inner surface of the ring-shaped portion is brought into contact with the rear outer surface of the mouth and neck, so that the front inner surface of the ring-shaped portion and the mouth are brought into contact with each other. A predetermined gap l is formed between the handle and the front outer surface of the neck, and the handle is centered around a thin hinge part 10 vertically disposed on the front end surface of the handle.
One side half 7a is formed so as to be expandable to one side with respect to the other side half 7b, and a wedge-shaped portion 11 is horizontally disposed on the upper rear end surface of the one side half. The wedge-shaped part is inserted into the gap through the through hole 9 bored in the front side of the ring-shaped part so that it can be held against the outer surface of the mouth and neck by the rear surface of the wedge-shaped part and the rear inner surface of the ring-shaped part. Features.

"Operation" For example, by grasping and pulling up the handle 7 from the state shown in FIG. Since the ring-shaped part does not come off from the mouth and neck when held, the bottle main body 1 can be easily carried via the handle member 2.

In addition, when attaching the member with handle 2, after loosely fitting the ring-shaped part 6 to the outer surface of the mouth and neck part 4 below the outward facing flange 5, the rear inner surface of the ring-shaped part is attached to the rear outer surface of the mouth and neck part. The member is moved forward until it comes into contact with the member. Then, in the gap (so-called play) l between the front inner surface of the ring-shaped part and the front outer surface of the mouth and neck area formed by the movement, the handle in the expanded state as shown in FIG. The wedge-shaped portion 11 attached to the one half 7a may be fitted by rotating the one half 7a so as to fold the one half over the other half. As a result, the rear surface of the wedge-shaped portion and the rear inner surface of the ring-shaped portion sandwich the outer surface of the mouth and neck, making it impossible for the ring-shaped portion to separate from the outer surface of the mouth and neck.

Embodiment FIGS. 1 to 3 show an embodiment of the present invention, in which 1 is a bottle body made of synthetic resin, and 2 is an elastically deformable member with a handle, which is also made of synthetic resin.

The bottle body 1 has a mouth and neck part 4 erected from the upper end of the body part 3 via a shoulder part, and an outward flange 5 protrudes from the outer surface of the middle part of the mouth and neck part.

The handle member 2 engages with the lower surface of the outward flange 5 to fit the ring-shaped part 6 into the mouth and neck part 4, and also extends the hollow rod-shaped handle 7 from the front outer surface of the ring-shaped part 6 in the front-down direction. It stands out as one.

The ring-shaped portion 6 is formed to a size that allows the outward flange 5 to pass through, and the rear inner surface of the ring-shaped portion is brought into contact with the rear outer surface of the mouth and neck. A predetermined gap l is formed between the front outer surface of the mouth and neck. In the illustrated example, relatively small plate-like protrusions 8a and 8b are formed on both the left and right sides of the inner surface of the ring-shaped part, and a relatively large plate-like protrusion 8c is formed on the rear part, and the upper surfaces of these protrusions form the outward facing flange 5. While engaging the lower surface, the front end surface of the rear projection 8c is in contact with the outer surface of the mouth and neck portion 4. In addition, the ring-shaped part is formed in an oval shape,
The gap l is set to be slightly larger than the sum of the projection height _h1 of the outward flange 5 and the engagement depth _h2 of the rear projection 8c with the outward flange 5. Furthermore, a through hole 9 is bored on the left side of the handle base portion of the ring-shaped portion.

The handle 7 has a thin hinge part 10 vertically installed on the front end surface of the handle, and a left half part 7a and a right half part 7b.
A wedge-shaped portion 11 slightly thicker than the gap 1 is provided horizontally at the upper rear end surface of the left half portion 7a.

The wedge-shaped portion 11 is inserted into the gap 1 through the through-hole 9 so that it can be held against the outer surface of the mouth and neck by the rear surface of the wedge-shaped portion and the front end surface of the rear protrusion.

Therefore, in this embodiment, since the ring-shaped portion 6 engages with the lower surface of the outward flange 5 at four points on the front, rear, left and right sides, the handle member 2 can be more firmly attached to the bottle body 1. Furthermore, when the ring-shaped portion 6 is mounted, the front and rear portions of the ring-shaped portion 6 are slightly reduced in diameter by elastic deformation, so that the protrusions 8a and 8b on both the left and right portions can easily get over the outward flange 5.

"Effects of the invention" As explained above, according to the invention, since the handle and the bottle body are formed separately, the design of each mold becomes easy, and a bottle with a handle can be easily and inexpensively formed. can do. In addition, since the handle is attached to the bottle body through the ring-shaped part, even a thin-walled bottle such as a biaxially stretched bottle can be easily made into a bottle with a handle. Since the grip is formed so as to be effectively fitted through the wedge-shaped portion attached to the handle, the attachment can be performed extremely easily.
