Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a biaxially stretched synthetic resin bottle with a base.

(Prior art) Conventionally, a bottle made of biaxially stretched synthetic resin with a frame-shaped base fitted and glued to the bottom was manufactured by Jikosho.
As seen in Publication No. 59-4916, the bottom part b of the synthetic resin bottle body a is formed into a spherical shape that bulges downward as shown in the second figure, so that even if the wall is thinned, it will not be affected by external pressure or the sealed state of the bottle. In order to prevent deformation due to internal pressure, and to provide further independence, a hook-shaped leg base c is fitted onto the bottom b and fixed with adhesive. When fitting this bottle body a to the base c, a hole is required to vent air from the base, and for this reason, it has previously been proposed to provide an air vent hole in the bottom wall d of the base c. However, in the publication mentioned above, there is a risk that the adhesive bonding the inner surface of the bottom wall d of the pedestal c and the bottom part b of the bottle body may flow out from the hole, so it is important not to damage the external damage of the pedestal c. Taking this into consideration, it has been proposed that a hole e is bored in the inner circumferential wall of the leg part f of the leg base c.

However, in such a configuration, the hole e is useful as an air vent hole, but the hole e is useful as an air vent hole.
This also serves as a hole for water to enter when the bottle body a is washed, and when the bottle body a is stood up to dry, the water that has entered into the base c can be completely removed because the hole e is drilled in the inner circumferential wall of the leg part f. There is an inconvenience that it does not drain naturally. Therefore, if water remains in the leg part f, when the bottle body a is packed in a cardboard box, the bottom of the cardboard box may become wet due to the residual water, damaging the cardboard box, or the remaining water may There is a problem of bad odors caused by rotting water.

Furthermore, since the leg base c is fitted onto the bottom part b of the bottle body a in an exposed state, it feels strange and has a problem of spoiling the appearance.

(Problems to be Solved by the Invention) The present invention solves these conventional problems, allows the bottle body to be fitted and bonded to the base without any trouble, and prevents water from entering the inside of the base during washing. It is an object of the present invention to provide a synthetic resin bottle with a base having a harmonious appearance.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems by forming the bottom of a biaxially stretched synthetic resin bottle body to bulge downward into a spherical shape. , in which a pedestal formed in a hook shape is fitted and adhered to the bottom, and an air hole is provided in the pedestal, an outer peripheral wall that tightly fits into the lower part of the body of the bottle main body of the pedestal, and the outer periphery. The air hole is provided in a region extending from the outer peripheral wall of the leg part to the bottom surface, which is formed by an inner peripheral wall formed upwardly and inwardly through a bent part connected to the lower end of the wall, and a shrink label is attached to the body of the bottle body. The air hole is sealed by integrally forming a coating on the outer surface of the leg from the outer circumferential wall of the leg base to the bottom surface of the leg.

(Example) The present invention will be explained below with reference to the drawings.

FIG. 1 shows one example of implementing the present invention.
In the drawing, 1 is a bottle body made of biaxially stretched synthetic resin, and the bottle body 1 has a body 2, a bottom 3 formed in a spherical shape below the body 2, and a neck provided above the body 2. A separately formed leg 5 is tightly fitted to the bottom 3 of the bottle body 1, and the bottom 3 is adhered to the inner surface of the leg 5 with adhesive. The pedestal 5 is made of ordinary thermoplastic synthetic resin, and has an outer peripheral wall 6 that fits tightly into the lower part of the body 2 of the bottle body 1.
An inner circumferential wall 7 is made to stand upwardly inwardly from the lower end of the bottle via a bent part, and a bottom wall 8 that supports the bottom part 3 of the bottle body 1 is connected to the upper end of this inner circumferential wall 7. It was integrally formed so as to be provided at a position that entered the space formed within the wall 6. An annular leg portion 9 having a substantially U-shaped cross section is provided between the lower end of the outer peripheral wall 6 and the lower end of the inner peripheral wall 7, with the inner surface of the bent portion opening upward. stand 5
When the bottom wall 8 of the bottle is provided with a joint 10 that bulges upwardly and inwardly, and the bottom 3 of the bottle body 1 is fitted to the base 5,
The bottom part 3 was completely seated on the joint part 10, and an adhesive was applied to the joint part 10 to bond them together.

Although the above configuration is not different from the conventional one, in the illustrated embodiment of the present invention, when the leg base 5 is fitted to the bottom 3 of the bottle body 1, the air in the base 5 is discharged. The hole 11 is inserted into the bottom surface 12 of the leg part 9 of the leg base 5.
It was drilled in.

From the body 2 of the bottle body 1 to the outer peripheral wall 6 of the footrest 5
A shrink label 13 is integrally formed so as to wrap around the outer surface of the leg section 9 to the bottom surface 12 of the leg section 9. Sealed.

In the illustrated embodiment, the bottom surface 12 of the leg portion 9 is formed into a curved surface, but the bottom surface 12 is formed into a curved surface.
It may be formed on a flat surface in order to stabilize the uprightness.

As mentioned above, in the bottle of the present invention, the air hole 11 is formed in the area extending from the outer circumferential wall 6 of the leg part 9 of the base 5 to the bottom surface 12.
When they are fitted together, the air in the base 5 is discharged from the air hole 11, so that the bottle body 1 and the base 5 can be easily and reliably fitted and bonded. Further, the syringe label 13 is formed by integrally covering the bottle body 1 and the leg base 5 after the bottle body 1 and the leg base 5 are fitted together and bonded, and the air hole 1
Since the bottle body 1 is sealed, water will not enter into the base 5 when washing the bottle body 1, and therefore, there will be no residual washing water as in the conventional case. Even if the product is packaged in a box, there will be no problems such as damage to the cardboard box due to moisture or generation of a bad odor due to residual water. Furthermore, since the leg stand 5 is integrally covered with the shrink label 13 on the body 2 of the bottle body 1, it has a harmonious appearance without any discomfort.

(Effect of the invention) As described above, according to the present invention, the outer circumferential wall that tightly fits into the lower part of the body of the bottle main body of the pedestal, and the bent part connected to the lower end of the outer circumferential wall, are raised upwardly and inwardly. An air hole is provided in the area extending from the outer circumferential wall of the leg to the bottom, which consists of an inner circumferential wall formed by Since the air holes are sealed by integrally covering the bottle body and the base, which are fitted and bonded together, the air holes are sealed with a Shrink label, which prevents water from leaking during washing. It does not get into the base, and even if the adhesion between the bottle body and the base is insufficient, they are integrated with a shrink label, so the base will not fall off from the bottle body. Furthermore, since the base is covered with a Shrink label, it is possible to provide a synthetic resin bottle with a base that has a harmonious appearance.
