Definitions
- the present invention relates to a relatively large synthetic resin bottle.
- the biaxially stretch molded resin or polyethylene terephthalate resin itself has excellent mechanical strength and transparency. O Many are used
- the biaxially stretch blow-molded synthetic resin body is roughly divided into a base having a hemispherical bulge at the bottom to increase the inner shojo strength and providing a leg at the bottom. -With the base cup attached and without the base cup attached, the center of the bottom is depressed inward to form legs on the body itself. There are some.
- the bent portion at the periphery where the bottom is depressed inward is used as a leg, the lowest point of the bent portion is that the leg is blow molded. Therefore, it is located more inward than the outer peripheral surface of the torso, and the bottom area for holding only the inwardly located part in the upright posture is small. It is.
- the base cup which is to be attached to the body, has a structure in which the bottom of the bottle body to be assembled has a hemispherical bulge.
- the height must be relatively large, and as a result, the proportion of the base cap occupying the entire appearance of the container increases, and He complained that the excellent design effects of the main body could not be fully exhibited, and had no ability to prevent the gigantic deformation of the bottom due to internal pressure.
- the present invention has been made in order to solve the above-mentioned problems in the prior art, and has a body in which the bottom center is inverted and depressed inward to form a leg.
- the present invention is also intended to prevent the occurrence of enormous deformation of the bottom due to internal pressure and to increase the impact resistance of the bottom of the body. It was targeted.
- Means of the present invention for achieving the above object are as follows:
- It has a biaxially stretched blow molded synthetic resin main body with a wide recessed groove recessed in the outer peripheral surface of the bottom that has a spherical surface.
- the upper half of a straight short cylindrical piece having an outer diameter approximately equal to the outer diameter of the body of the main body is fitted into the mounting groove of the main body to form an inner peripheral surface.
- the lower half is positioned with the lower end lower than the lowermost lower end of the bottom of the bottle body.
- a concave groove formed on the outer peripheral surface of the bottom of the bottle body the depth of the groove is increased from the bottom to the bottom. Is effective.
- the leg tube piece which is in surface contact with the groove bottom surface of the mounting groove is formed.
- Inner peripheral surface formed on assembled cylinder As a result, the assembled spherical arc surface has a tapered surface structure that expands upward, so that simply pushing the bottom of the bottle main body against the leg from above, The inner peripheral troublesome portion of the assembled cylinder piece fits into the assembly concave groove, and the assembling of the leg body to the main body is achieved.
- the depth of the mounting groove is configured to be larger downward, and the height of the groove is relatively large at the groove edge below the mounting groove.
- the projections are formed at the lower end of the spherical arc surface where the leg is assembled and the cylindrical piece is assembled so as to correspond to the deepened mounting groove. Stopping force This means that it is strongly locked to this bulging part, and by the locking of the locking ridge to this bulging part, the fitting of the leg to the main body can be assembled. Will be very strong.
- the legs are mounted on the outer surface by fitting into the spherical outer surface of the bottom at the bottom, even if the internal pressure of the field main body becomes large, the legs can be mounted.
- the legs support the increased internal pressure, so there is no force to bulge and deform the bottom greatly due to the internal pressure.
- the lower end of the leg tube since the lower end of the leg tube is always located below the lower edge of the bottom, the lower end of the leg tube provides a single leg.
- the leg provided by this leg tube piece exhibits a constant self-sustaining function, always maintaining a constant shape, regardless of the bulging deformation of the bottom.
- the main body is a separate body, and the legs provide the legs.
- the impact does not act directly on the bottom of the main unit, and the legs always function as a cushion. Even if it is formed of acrylonitrile resin, it is possible to obtain a solid body having impact resistance at the bottom.
- FIG. 1 is an overall front view of a leg according to one embodiment of the present invention, in which only a leg is partially longitudinally cut.
- FIG. 2 is an enlarged vertical sectional view of a circled portion in FIG.
- 1 is a biaxially stretched blow molded synthetic resin main body, and a bottom 3 formed integrally with the lower end of the body 2 of the main body 1.
- the central part is depressed inward to form a concave part 6, thereby forming a part which has functioned as a conventional leg part around the concave part 6.
- the bottom 3 has an arcuate outer peripheral surface, that is, a portion close to the place where the bottom 3 is connected to the body 2 has a wide vertical groove.
- the mounting groove 4 is formed by increasing the depth of the groove as it goes down. For this reason, a bulging portion 5 having a relatively large protruding height is formed on the lower groove edge of the assembling concave groove 4.
- the leg 7 has a straight short cylindrical shape as a whole, and a mounting ball which is an inner peripheral surface of the mounting cylinder piece 9 which is an upper half portion.
- the arc surface 10 is a spherical arc surface having the same radius of curvature as the groove bottom surface of the assembling concave groove 4, and the assembling forming the assembling spherical arc surface 10 is as follows. At the lower end of the inner peripheral surface of the tube piece 9, a locking ridge 11 is formed to protrude from the lower end ⁇ of the mounting groove 4.
- the locking ridge 11 Since the locking ridge 11 has a pointed protruding cross-sectional structure, it has a structure that is relatively easily elastically deformed.
- the spherical arc surface 10 to be assembled becomes a guide surface when the leg 7 is fitted to the bottom 3.
- the main body 1 and the leg 7 are assembled and guided correctly to each other, and then, by a forcible pushing force, the locking strip 11 is elastically deformed and rides over the bulging portion 5. ⁇ The fitting of the leg 7 to the main body 1 is achieved.
- the legs 7 assembled and attached to the bottom 3 firmly hold the assembly to the bottle body 1 by the engagement of the engagement strips 11 with the bulging portion 5.
- the legs 7 are made of a shock-resistant high-strength synthetic resin material, and the field body 1 is made of an acrylonitrile resin. Even in this case, the bottom 3 of the main body 1 is sufficiently protected against impact from the outside.
- the leg has a straight short cylindrical shape whose outer diameter is almost equal to the outer diameter of the trunk, which is the largest outer diameter of the main body.
- the lower end of the lower part of this short cylinder is used as the leg surface.
- the base area for holding and standing the body is increased, and the standing posture of the body can be stably held.
- the height of the legs is only slightly larger than the bottom with the central part depressed inward and curved, so that the height is higher than the height of the vertically long body. It is small enough to reduce the effect of the legs on the overall appearance of the body.
- the legs are fitted and assembled on the outer peripheral surface of the bottom, it is possible to prevent the occurrence of large illegal bulging deformation of the bottom due to the internal pressure in the bottle body. As a result, it has a bottom with a structure in which the central portion is inverted and depressed inward. The internal pressure resistance of the main body can be sufficiently increased.
- Assembling of the legs to the container body is achieved by simple fitting, so that the assembling operation of the bottle body and the legs is easy, and the assembling of both is performed at the opposing parts of the two. It is achieved accurately because it is achieved by mutual guidance.
- the bottom of the bottle body is made external by molding the legs with synthetic resin material with high impact resistance and cushioning action. It can protect against impacts from the body, which means that even if the main body is made of a material with lower impact resistance, for example, acrylonitrile resin However, it is possible to obtain a strong body against impacts caused by dropping.
