Description

[Detailed description of the invention] "Industrial application field" The present invention relates to biaxially stretched bottles that increase the strength of the bottle wall by biaxially stretching a synthetic resin material and are mainly used as containers for carbonated beverages such as draft beer. .

``Prior Art'' Seed bottles of this type are commonly equipped with handles for ease of carrying. However, in the case of conventional products with handles, many of the handles protrude outward from the bottle shape, which not only obstructs handling such as transportation and storage, but also is used in vending machines. There is an inconvenience that it cannot be done.

Therefore, various biaxially stretched bottles have been devised that have a structure in which the handle can be folded up when not being carried.For example, a design described in Japanese Utility Model Application Publication No. 174429/1983 is known. The container of this invention includes a bottle made of synthetic resin formed by biaxial stretching, a cylindrical base fitted to the outer surface of the lower body of the bottle, and an upper part fitted to the outer surface of the body of the bottle. It is formed from a cover and a handle whose upper and lower ends are connected between the rear outer surface of the upper cover and the rear outer surface of the leg base. A pair of left and right board parts are protruded rearward from the rear surface of the upper cover at an appropriate interval, and engagement plate parts are protruded from the rear ends of the board parts in mutual directions, and the engagement plate parts A first engaging protrusion is attached to the tip of the inner surface. In addition, the handle has a support plate portion protruding from both left and right edges of the upper end of the plate-shaped grip portion via the first hinge portion, which is slidably fitted between the front surface of the engagement plate portion and the rear surface of the upper cover. , a second engagement protrusion is attached to the rear end of both the left and right support plate parts, and a second hinge part is formed in the support plate part immediately inward of the second engagement protrusion. .
When the upper part of the handle is pulled rearward, the support plate portion between the first hinge part and the second hinge part is pulled out from between the front surface of the engagement plate part and the rear surface of the upper cover, and
The first and second hinge parts are bent, and the support plate part thereof is bent forward, and further, the second engagement protrusion at the tip of the support plate part engages with the first engagement protrusion, and the support plate part It is formed to prevent it from falling out.

"Problem to be solved by the invention" In the above conventional example, the second engagement protrusion attached to the rear end of the support plate is attached to the outer surface of the first engagement protrusion attached to the front end of the engagement plate. However, when the handle is used to lift the container, a large load is placed on the engagement plate and the engagement plate tends to be elastically deformed, causing the handle to wobble and making it difficult to pour out the stored liquid. ,
In the worst case, there was a risk that the second engaging protrusion would climb over the first engaging protrusion and the upper end of the handle would come off the outer surface of the upper cover. In order to eliminate these drawbacks, it is necessary to take measures such as increasing the rigidity of the engaging plate portion, which tends to increase the cost.

This proposal aims to eliminate such inconveniences.

"Means for Solving the Problem" A biaxially stretched synthetic resin bottle 1 has a cylindrical leg base 6 and an upper fitting member 7 fitted and fixed to the lower and upper parts of the body 3. In the axially stretched bottle, a pair of left and right engaging parts 10, 10 are attached to the lower rear surface of the upper fitting member at an appropriate interval, and vertical grooves are formed in the front surfaces of the sides facing each other of the engaging parts. 1
