Description

[Detailed explanation of the idea] "Industrial application field" This proposal relates to a barrel-shaped synthetic resin bottle with a handle.

"Prior art" For example, Figure 2a of Utility Model Application Publication No. 58-180129,
The device shown in b consists of a bottle made of synthetic resin, a cylindrical pedestal fitted to the outer surface of the lower end of the body of the bottle, and a lower end of the cylindrical body fitted to the outer surface of the upper end of the body of the bottle. At the same time, the inner circumferential edge of an inward flange-like wall attached to the upper end of the cylinder by descending downward and inwardly is engaged with the outer surface of the mouth and neck part of the bottle, and further, a vertically penetrating wall is attached to the lower rear surface of the cylinder. an upper fitting member having a cylindrical portion attached thereto, and a lower part of a mounting plate portion having an inverted L-shape on the side protruding from the front middle portion of the gripping portion and having a fork-shaped hanging plate portion into the cylindrical portion. At the same time, the burrs attached to the lower ends of both the left and right legs of the mounting plate are engaged with the lower ends of the cylindrical parts, and the rear surface of the engagement plate protruding diagonally downward and forward from the upper end of the grip is inserted into the inner part. and a handle engaged to the rear front surface of the facing flange-like wall.

``Problem to be solved by the invention'' In the above conventional example, the handle is prevented from coming off upward by the engagement between the burr at the lower end of the mounting plate and the lower end of the cylinder of the upper fitting member. If the capacity of the body is large, there is a risk that the engagement may be disengaged due to the weight of the stored liquid, and the handle may fall off from the rear surface of the upper fitting member. In addition, since the handle is attached to the rear surface of the upper fitting member via the mounting plate with an inverted L-shape on the side, if the capacity of the bottle is large, the mounting plate with an inverted L-shape on the side becomes elastic due to the weight of the stored liquid. There was an inconvenience that the handle was prone to wobbling when bent.

This proposal aims to eliminate such inconveniences.

"Means for Solving the Problem" In a barrel-shaped synthetic resin bottle in which an upper fitting member 4 is fitted to the upper end of the body 3 of a biaxially stretched synthetic resin bottle 1, the upper fitting member 4 A dovetail groove 5 with an upper end surface opening is provided vertically in the upper part of the rear face, and a pair of engaging pieces 7, 7 are provided from the lower part of the rear face below the dovetail groove 5, respectively, with burrs 6, 6 on the outer surfaces that do not face each other. The handle 2 is provided with an arcuate grip plate 9 integrally formed on the rear side from a support plate 8 extending vertically along the rear surface of the upper fitting member 4; The handle 2 has a shape in which a dovetail 10 is provided in the upper part and a window 11 in the lower part.
The upper fitting member 4 is attached to the rear surface of the upper fitting member 4 by being pushed and fitted.

"Operation" When the dovetail 10 is fitted into the dovetail groove 5 from the state shown in FIG. A handle 2 is attached to the rear surface of the upper fitting member 4. In this attached state, the handle 2 is prevented from coming off backwards by the engagement between the dovetail groove 5 and the dovetail 10, and the engagement between the front surface of the burrs 6, 6 and the rear surface of the support plate 8 on both the left and right sides of the window 11. Furthermore, the engagement between the lower ends of the engaging pieces 7 and the lower peripheral edge of the window 11 prevents the handle 2 from coming off upward, so that the handle 2 can be securely attached to the upper fitting member 4.

"Example" The container of the present invention is formed of a bottle 1, an upper fitting member 4 fitted to the outer surface of the upper part of the bottle, and a handle 2 attached to the rear surface of the upper fitting member.
is formed by biaxially stretching a cold parison made of, for example, a saturated polyester resin, 3 is a body part, 12 is a
is the bottom, 13 is the shoulder, and 14 is this shoulder 13.
This is a cap attached to the mouth and neck (not shown) that stands up from the mouth. The bottom part 12 is formed to bulge downward in a so-called potbelly shape, and as shown in FIG. It is set as.

From the middle part of the inner circumference of the upper fitting member 4, there is an inward flange 1 which curves downwardly and hangs down toward the center.
5 is integrally provided, and this inward flange 15
The upper fitting member 4 is firmly fixed to the bottle body 1 by engaging the inner peripheral edge with the peripheral edge of an outward facing flange (not shown) at the base of the mouth and neck. Further, a dovetail groove 5 with an opening on the upper end surface is vertically provided on the upper rear surface of the upper fitting member 4, and burrs 6, 6 are provided on the outer surfaces that do not face each other from the rear surface portion of the upper fitting member below the dovetail groove. A pair of engaging pieces 7, 7 are arranged to face each other on the left and right and protrude rearward. Furthermore, the upper fitting member 4 is formed to have a somewhat larger outer diameter than the body 3 described above, and has a barrel-shaped outer shape together with the potbellied bottom 12 described above.

The handle 2 includes an arcuate, double-plate-shaped grip plate 9 integrally hanging from a support plate 8 extending vertically along the rear surface of the upper fitting member 4, and a dovetail 10 on the upper front surface of the support plate 8. and a window 1 at the bottom of the support plate 8.
1 is bored, and with the dovetail 10 fitted into the above-mentioned dovetail groove 5, the above-mentioned engagement pieces 7, 7 are attached to the window 11.
The handle 2 is attached to the rear surface of the upper fitting member 4 by being pushed and fitted.

"Effect of the invention" The present invention has the above structure, and the handle 2 is provided in the dovetail groove 5 formed on the upper rear surface of the upper fitting member 4.
A pair of engaging pieces 7, 7 are fitted with dovetails 10 formed on the upper front surface of the support plate 8, and a pair of engaging pieces 7, 7 are provided with burrs 6, 6 on outer surfaces that do not face each other from the lower rear surface of the upper fitting member 4. The dovetail grooves 5 are arranged so that they face each other on the left and right and protrude rearward, and their engaging pieces are pushed into the windows 11 drilled in the lower part of the support plate 8 of the handle.
Fitting of dovetail 10 and burrs 6, 6 front and window 11
The handle 2 is prevented from coming off backward by engagement with the rear surface portions of the support plates on both the left and right sides, and the engagement pieces 7,
By engaging the lower end of 7 and the lower peripheral edge of the window 11, the handle 2
The handle 2 can be prevented from coming off upward, and the handle 2 can therefore be firmly attached to the rear surface of the upper fitting member 4. A pair of engaging pieces 7, 7 each having a burr 6, 6 attached to a non-opposed surface protrude from the rear lower part of the upper fitting member 4, facing each other from side to side. The burrs 6, 6 are fitted into the window 11 drilled in the lower part of the
Since it is formed to engage with the rear surface of the support plate 8 on both the left and right sides of the window 11, the upper fitting member 4 can be stably attached to the handle 2, and even if the capacity of the bottle 1 is large, the handle 2 can be used. When you lift the bottle, handle 2
No wobbling occurs. Furthermore, the attachment part of the handle 2 is formed only on the upper fitting member 4, and there is no need to process the bottle 1, which is advantageous in terms of manufacturing.Moreover, the handle 2 is a single component with a simple shape, making it easy and inexpensive. can be produced.
