Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a biaxially stretched bottle with a handle.

[0002]

2. Description of the Related Art It has been practiced to integrally mold a bottle with a handle from a synthetic resin material, but it is extremely difficult to make a biaxially stretched bottle into an integrally molded bottle with a handle. For this reason, as shown in, for example, Japanese Utility Model Application Laid-Open No. 2-108845, a separately provided cylindrical body with a handle is fitted to the mouth and neck of a biaxially stretched bottle.

[0003]

In the above-mentioned conventional bottle, the handle is located above the bottle. Therefore, when the length of the bottle is large, the bottle is held only by the handle to discharge the liquid. It is difficult to tilt the bottle.

In the present invention, a concave portion is provided in the rear wall of the bottle body, and a small hole is formed in the body rear wall portion above and below the concave portion. The locking plate is fitted so that it cannot be pulled out, and the locking plate is fixed in the small hole easily and reliably by fitting the embedded plate.

[0005]

The rear wall of the body 2 has a concave portion 4 having openings on the rear surface and both left and right sides, and small holes 5 having the same inner diameter in the front and rear openings on the upper and lower rear wall portions of the concave portion. And a holding plate 9 into the small holes 5 and 5 described above.
A pair of locking plates 11, 11 projecting forward from the front edge facing the fitting holes 10, which are formed vertically, and having a pair of return claws 12, 12 fitted on the front outer surface, are fitted into The handle comprises a synthetic resin handle 8 spanned between the rear wall portions, and embedding plates 13 and 13 fitted into the fitting holes 10 and 10 and between the locking plates by driving in from behind. The distance between the wall surfaces of the small holes in front of the double-return claws and the double-return claws is increased through the double-return claws and the rear end of the double-return claws by expanding the front gap between the two locking plates by driving the embedded plate. The distance between them was larger than the rear diameter of the small holes 5,5.

[0006]

The recesses 4 are provided in the rear wall of the bottle body. The small holes 5 are provided in the upper and lower rear walls of the bottle body. Claws 12,12 projecting forward from
The locking pawls 12, 11 are fitted into the locking plates 11, 11 as shown in FIG. 3 and the embedding plates 13, 13 are driven in from the rear ends of the fitting holes so that the return claws 12, 12 are moved outward as shown in FIG. Overhang, so return nail 12,12
However, the pull-out is prevented, so that the handle can be securely attached.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a biaxially stretched PET bottle, in which a mouth-and-neck portion 3 with an outward flange is erected from the upper end of a body 2 via a shoulder. The rear wall of the body 2 is arbitrarily defined and has a concave portion 4 having an opening on the rear surface and both left and right side surfaces, and a small hole having a rear surface opening and the same front and rear inner diameter as shown in FIG. 5, 5 are formed.

Reference numeral 8 denotes a handle made of a synthetic resin, which is formed with fitting holes 10 at the upper and lower sides of the gripping plate 9 and moves the locking plates 11 and 11 forward from the upper and lower portions of the front edge of the fitting hole. Protrude. Return claws 12, 12 are attached to the front outer surface of the locking plate. The locking plates 11 and 11 with the return claws can be inserted into the small holes 5 and 5 above and below the recess.

Reference numeral 13 denotes the fitting holes 10, 10 and the locking plates 11, 11.
It is an embedding plate which is fitted so as not to be able to be pulled out, and may be formed integrally with the handle 8 or may be formed separately. In the case of integral molding, as shown in FIGS. 2 and 3, the outer peripheral portion of the front end of the embedding plate and the outer edge of the rear end of the fitting holes 10, 10 are connected by a thin portion 14 which can be broken. A locking ridge 15 is preferably provided around the rear periphery of the embedding plate, and the length of the embedding plate is, as shown in FIG.

It is better to provide it shorter than to the trailing edge. The embedded board 13,1
3 is the distance between the front portions of the locking plates by inserting the embedding plate 13 into the fitting hole and between the locking plates 11, 11 from the state in which the locking plates 11, 11 are inserted into the small holes 5, 5. By the widening, each distance between the wall portion of the front of the small hole where the double return nail and the double return nail contact,

The fitting of the locking plates 11, 11 into the small holes 5, 5 is performed by insert molding, in which the grip 8 is fixed in the mold in advance, and the bottle 1 is biaxially stretched. Is also possible.

[0011]

[Effects of the Invention] The present invention has the above-described configuration, and has a bottle recess 4.
Into the small holes 5, 5 formed in the upper and lower rear wall portions, fitting holes 10, 10 formed in the upper and lower sides of the gripping plate 9, projecting forward from the facing portion of the front edge, A pair of locking plates having 12
11 and 11 are fitted, and the embedding plates 13 and 13 are driven into the fitting hole and between the locking plates from the rear end of the fitting hole to reduce the distance between the outer surface rear ends of the return claws 12 and 12. Since the diameter of the rear portion of the small holes 5 is larger than that of the small holes, the upper and lower handles can be securely and easily fixed to the biaxially stretched bottle.

Since the small holes 5 and 5 need only be formed to have substantially the same inner diameter in the front and rear during bottle molding, the small hole forming die portion may also be a rod shape having substantially the same outer diameter in the front and rear. After the molding of the part and the bottle molding, the mold part is easily die-cut.

Further, the distance between the wall portions at the front of the small holes where the return claws 12 and 12 come into contact is increased by embedding the plates 13 and 13 inserted between the locking plates 11 and 11 at the front portions of the locking plates. Return claws 12, 12 attached to the front outer surfaces of both locking plates by widening the gap
Is performed by pushing and expanding the wall portion of the front portion of the small hole where the return claw contacts, so that the locking plates 11, 11 fitted with the embedded plate sandwiched into the small hole play back with respect to the small hole. It can be securely fixed without any.

Further, since the bottle is a biaxially stretched bottle, the distance between the wall portions at the front portion of the small hole where the double hooks come into contact with each other by expanding the interval between the front portions of both locking plates by driving the embedding plate is considered. It can be done without difficulty due to the viscosity of the axial drawing bottle.
