SYNTHETIC RESIN BOTTLE-SHAPED CONTAINER
This invention relates to a relatively large synthetic resin bottle-shaped container.
Biaxially-oriented blow-molded 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-molded bottle-shaped containers are generally divided into two groups: those having a semispherically bulged bottom for an enhanced internal pressure resistivity and provided with a base cup that serves as a stand, and those having a bottom with an internally depressed central area that serves as a stand for self-standing without a base cup.
A bottle-shaped body having a self-standing capability is advantageous over a bottle-shaped body provided with a base cup in terms of easy cleaning, sterilization, molding and assembling, as well as of overall appearance.
However, 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.
More specifically, when a circular peripheral portion of the bottom that serves as a stand for the bottle-shaped body is formed by depressing the central area of the bottom by blow-molding, the circular peripheral portion of the bottom is inevitably located nearer to the center of the bottom than r, CA 0203S902 1998-04-1~
the outer circumference of the body portion. This fact results in the reduced bottom area that supports the bottle-shaped body in an upright condition.
Moreover, when a high internal pressure is applied to such a self-standing bottle-shaped body, the bottom portion forming a stand is subjected to a relatively large expansion, which in turn adversely affects the self-standing capability of the bottle-shaped body to a significant extent. Such an expansion can result in deformation.
On the other hand, in a bottle-shaped body provided with a base cup for keeping it upright, the height of the base cup is required to be of a relatively large size 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 disproportional large base cup. Moreover, the bottom of such a bottle-shaped body can not protect expansion and deformation when a large internal pressure is applied thereto.
Besides, a biaxially-oriented blow-molded 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.
In view of the above described problems, it is therefore an object of the present invention to provide a bottle-shaped container having a depressed area at the center of the bottom provided with a pedestal useful as self-standing means, ~, ., .
CA 02035902 1998-04-1~
.,_ wherein the bottom has an enhanced and stable self-standing capability and protects any expansion and deformation, and at the same time is highly resistive to shocks.
According to the invention, the above object is achieved by providing a synthetic resin bottle-shaped container comprising a biaxially-oriented blow-molded bottle-shaped body having a relatively long press-fit recess on a curved outer peripheral surface area of a curved bottom portion and a cylindrical 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 container.
The upper portion has a curved inner peripheral surface closely engaged with the press-fit recess. The cylindrical pedestal body further has a hollow pedestal-shaped lower half portion for accommodating the bottom of the bottle-shaped body portion, so that a lowest end of the lower half portion of the pedestal body is positioned below a lowest end of the bottom portion of the body portion.
The press-fit recess preferably is formed to be progressively deeper toward the lower end thereof, on the curved outer peripheral surface area of the bottom portion, and the matching curved 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 downward the bottle-shaped body until the curved outer peripheral surface area of the bottom of the bottle-shaped body is completely in contact with the matching CA 0203~902 1998-04-1~
-curved inner peripheral surface area of the upper half portion of the cylindrical pedestal body.
When 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.
With such an arrangement, since the curved outer peripheral surface of the bottom of the bottle-shaped body is closely engaged with the inner surface of the pedestal body, an enhanced inner pressure is supported by the inner surface of the pedestal body, and the bottom of the bottle-shaped body is protected against any undesirable expansion and de ormation due to such an enhanced inner pressure.
Besides, since the lowest end of the lower half portion of the pedestal body is always positioned below a lowest end of the bottom of the bottle-shaped body, the lowest end surface of pedestal body provides a firm and stable support for the bottle-shaped body regardless of expansion and deformation of its bottom.
Moreover, since the pedestal body is not integral with the bottle-shaped body and the pedestal body serves as a shock absorber that effectively protects the bottom of the CA 0203~902 1998-04-1~
.",_~
bottle-shaped body from cracks and fissures, the bottom of the bottle-shaped body has sufficiently high sensitivity to any shocks even if the bottle-shaped container is made of acrylonitrile resin and it is dropped from a high position.
Now a preferred embodiment of the present invention will be described in detail, by referring to the accompanying drawings in which:
Fig. 1 is a front view of the embodiment showing the pedestal body in partial longitudinal cross section.
Fig. 2 is an enlarged longitudinal sectional view showing only the encircled area in Fig. 1.
PREFERRED EMBODIMENT
In Figs. 1 and 2, reference numeral 1 denotes a biaxially-oriented blow-molded bottle-shaped body made of synthetic resin having a bottom portion 3 integrally formed at a lower end of the body portion 2 of the bottle portion 1.
The bottom portion 3 has a depressed area 6 at the center thereof and a peripheral projecting area surrounding the depressed area which can serve as a stand or support structure in a conventional hollow bottle-shaped body of the self-standing type.
Now referring to Fig. 2, a relatively long press-fit recess 4 is formed on the outer peripheral surface area of a curved surface of the bottom portion 3 near the body portion 2 and is so configured that the depth of recess 4 is progressively increased as it approaches a lower end thereof, thus forming an annular groove 4a. A relatively high CA 0203~902 1998-04-1~
projecting portion 5 is formed at the lower end of the press-fit recess 4.
On the other hand, 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, i.e. having a substantially vertical outer perimeter, and 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 the both 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 is projected at the lower end of said curved inner surface area 10 of the upper half cylindrical portion 9 of the pedestal body 7 and is closely engaged with the lower edge of the press-fit recess 4 when assembled.
With such an arrangement, a step 12 is formed at the boundary between the press-fit cylindrical upper half portion 9 and the lower half pedestal portion 8 of the pedestal body 7, such that 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 can easily pass over the projecting portion 5 for engagement of ~':
~?
CA 0203~902 1998-04-1~
.~
the bottle-shaped body 1 and the pedestal body 7 when they are assembled together.
Because of the engagement between the rib 11 and the projecting portion 5, 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 against shocks and therefore can provide satisfactory protection for the bottle-shaped body 1 against external shocks even when the bottom portion 3 of the bottle-shaped body 1 is made of acrylonitrile resin.
Because of the construction described above, the present invention provides the following advantages.
Firstly, since 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, a flat bottom surface of the lower end of the pedestal body provides the stable support for the bottle-shaped body in its upright position.
Secondly, since the overall height of the pedestal body is only slightly greater than that of the bottom portion having a depression at the center thereof, the pedestal body has a sufficiently reduced height relative to that of the elongated bottle-shaped main body. ~onsequently, the pedestal body does not provide poor impression of the container in appearance.
CA 0203~902 1998-04-1~
Thirdly, since the pedestal body is tightly press fitted to the recess forming 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.
Additionally, since 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.
Finally, since 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 damages when the container is dropped even if the container is made of a material having a relatively poor shock resistivity such as acrylonitrile resin.
