Definitions

  • the present invention relates to a relatively large synthetic resin bottle-shaped container.
  • Biaxially oriented blow-moulded bottle-shaped containers made of acrylonitrile resin or polyethylene terephthalate resin are popularly used because of their mechanical strength, transparency and other excellent properties.
  • Such biaxially oriented blow-moulded bottle-shaped containers are generally divided into two groups:
  • a bottle-shaped body having a self-standing capability is advantageous over a bottle-shaped body provided with a base cup in terms of ease of cleaning, sterilization, moulding and assembling as well as of overall appearance.
  • a self-standing bottle-shaped body has only a small bottom area that supports the bottle-shaped body relative to the cross sectional area of a body portion and therefore is less stable when it stands by itself.
  • the height of the base cup is required to be relatively large in order to accommodate the outwardly projecting semispherical bottom portion of the bottle-shaped body so that the overall appearance of the bottle-shaped container will be aesthetically poor, because of the disproportionately large base cup.
  • the bottom of such a bottle-shaped body is not protected from expansion and deformation when a large internal pressure is applied thereto.
  • a biaxially oriented blow-moulded bottle-shaped container made of acrylonitrile resin is insufficiently resistive to shocks applied to the bottom and can produce cracks and fissures on the bottom when it is inadvertently dropped.
  • US-A-3,927,782 describes a previously proposed base for a round bottomed container.
  • the base comprises a central bottom panel, a connecting ring for coupling the base to the container and an annular support channel joining the bottom panel to the ring.
  • the annular support channel includes parallel channel walls and a groove therebetween.
  • the inner channel wall being smaller in the axial direction than the outer channel wall.
  • the present invention is directed to a synthetic resin bottle-shaped container comprising; a biaxially-oriented blow-moulded bottle-shaped body having a press-fit recess on a curved outer peripheral surface area of a curved bottom portion; and a pedestal body having a straight and cylindrical upper half portion with an outer diameter substantially equal to that of a body portion of the bottle-shaped body and a pedestal-shaped lower half portion; in which the upper half portion of the pedestal body is so configured as to be closely engaged along its length with the press-fit recess on its curved inner peripheral surface, and the pedestal-shaped lower half portion of the pedestal body is cylindrical and so configured as to accommodate the bottom of the bottle-shaped body so that the lowest end of the lower half portion of the pedestal body is positioned below the lowest end of the bottom portion of the body.
  • the press-fit recess formed on the curved peripheral surface area of the bottle-shaped body is preferably so formed that the recess is progressively deeper toward the lower end thereof.
  • the press-fit recess is formed progressively deeper toward the lower end thereof on the curved outer peripheral surface area of the bottom portion, and the matching curved inner surface area which is formed on the inner peripheral surface of the upper half portion of the cylindrical pedestal body is tapered toward the upper end thereof. Therefore, the bottom of the bottle-shaped body is closely engaged with the pedestal body by simply pressing the bottle-shaped body downwards until the curved outer peripheral surface area of the bottom of the bottle-shaped body is completely in contact with the matching curved inner peripheral surface area of the cylindrical upper half portion of the pedestal body.
  • the press-fit recess formed on the curved outer peripheral surface area of the bottle-shaped body is so configured that the recess is progressively deeper toward the lower end thereof and a relatively high projecting portion is provided at the lower end of the press-fit recess, a press-fit rib projecting at the lower end of the curved inner peripheral area of the cylindrical upper half portion of the pedestal body is closely engaged with the high projecting portion to produce a firm and stable engagement between the bottle-shaped body and the pedestal body.
  • the lower end surface of the pedestal body provides a firm and stable support for the bottle-shaped body regardless of expansion and deformation of its bottom.
  • the pedestal body is not integral with the bottle-shaped and the pedestal body serves as a shock absorber that effectively protects the bottom of the bottle-shaped body from cracks and fissures, the bottom of the bottle-shaped body has sufficiently high resistance to any shock even if the bottle-shaped container is made of acrylonitrile resin and it is dropped from a high position.
  • a biaxially-oriented blow-moulded bottle-shaped body portion 1 made of synthetic resin.
  • a bottom portion 3 is integrally formed at the lower end of the body portion 2 of the bottle portion 1.
  • the bottom section 3 has a depressed area 6 at the centre thereof and a peripheral projecting area surrounding the depressed area can serve as a stand or support structure in a conventional hollow bottle-shaped body of the self-standing type.
  • a relatively long press-fit recess 4 is formed on the outer peripheral surface area of the curved surface of the bottom portion 3 near the body portion 2.
  • the recess 4 is so configured that its depth is progressively increased as it approaches the lower end thereof. Therefore, a relatively high projecting portion 5 is formed at the lower end of the press-fit recess 4.
  • a pedestal body 7 for supporting the bottle-shaped body 1 is formed as a whole in the form of a short and straight cylinder.
  • An upper half cylindrical portion 9 of the pedestal body 7 is provided with a curved inner surface area 10 matching the outer peripheral surface area of the press-fit recess 4. Since both the curved surfaces have a same radius of curvature, they are closely engaged with each other in a press-fit manner when assembled.
  • a press-fit rib 11 projects from the lower end of the curved inner surface area 10 of the upper half cylindrical portion 9 of the pedestal body and is closely engaged with the lower edge of the press-fit recess 4 when assembled.
  • the projecting portion 5 does not constitute any obstacle when the bottle-shaped body 1 and the pedestal body 7 are assembled.
  • the press-fit rib 11 is so sectionally constructed in a sharp top shape that it can be resiliently deformed.
  • the curved inner surface area 10 is so tapered toward the upper end thereof that it provides a guide surface for properly engaging the bottle-shaped body 1 with the pedestal body 7.
  • the press-fit rib 11 can be resiliently deformed and easily pass over the projecting portion 5 for engagement of the bottle-shaped body 1 and the pedestal body 7 when they are assembled together.
  • the pedestal body 7 is strongly fitted to the bottom portion 3 of the bottle-shaped body 1 once they are assembled.
  • the pedestal body 7 is made of a synthetic resin material which is highly resistive to shock and therefore can provide satisfactory protection for the bottle-shaped body 1 against external shock even when the bottom portion 3 of the bottle-shaped body 1 is made of acrylonitrile resin.
  • the present invention provides the following advantages.
  • the pedestal body is formed in the form of a short and straight cylinder having an outer diameter substantially identical with that of the body portion of the bottle-shaped container, the flat bottom surface of the lower end of the pedestal body provides the stable support for the bottle-shaped body in its upright position.
  • the pedestal body since the overall height of the pedestal body is only slightly greater than that of the bottom portion having a depression at the centre thereof, the pedestal body has a sufficiently reduced height relative to that of the elongated bottle-shaped main body. Consequently, the pedestal body does not provide a poor impression of the container in appearance.
  • the pedestal body is tightly press fitted to the outer peripheral area of the bottom portion of the bottle-shaped body, it can effectively prevent any expansion and deformation of the bottom portion occurring due to an enhanced internal pressure. Consequently, the resistance against the inner pressure of the bottle-shaped body having a depressed central area at the bottom portion can be considerably increased.
  • the bottle-shaped body is closely engaged with the pedestal body by a simple press-fit operation, the two bodies can be assembled without any difficulty. Moreover, since the two bodies are conveniently and mutually guided to a proper position, they can be accurately assembled.
  • the pedestal body is made of a highly shock-absorbing synthetic resin material, it can effectively protect the bottom portion of the bottle-shaped body from external impacts, and prevent the bottle-shaped body from damage when the container is dropped even if the container is made of a material having a relatively poor shock resistance, such as acrylonitrile resin.
