Definitions

  • the present invention relates to a biaxially blow-molded bottle-shaped container made of synthetic resin, and more particularly, to a construction of portions which contact with each other when said bottle-shaped containers are stood upright to be adjacent to each other.
  • Biaxially blow-molded bottle-shaped container made of synthetic resin such as polyethylene terephthalate resin are each filled with contents, sealed by a cap, applied with a label and packed in a corrugated card-board box by a packer, while being traveled.
  • a quantity of synthetic resin material required to mold a bottle-shaped container is made as small as possible to form a bottle-shaped container at less cost. Accordingly, the blow-molded bottle-shaped container is molded by sufficiently orienting a parison. Accordingly, a wall thickness of a body of the bottle-shaped container which forms a main portion of a content receiving portion is very thin.
  • blow-molded bottle-shaped container Since the blow-molded bottle-shaped container is heavy when it is filled with a content liquid, if the container is slidably moved even on a smooth plane, a considerable sliding resistance occurs. Since the wall thickness of the body which forms a main portion of a bottle-shaped container is thin, when a strong lateral load is applied to the body, it becomes easily depressed and deformed. Since the uprightness of the bottle-shaped container is not good, when a number of blow-molded bottle-shaped containers are arranged to be adjacent to each other in an upright attitude, portions of the body contacted with the adjacent blow-molded bottle-shaped containers are not constant.
  • the sliding resistance produced between the conveying surface and the blow-molded bottle-shaped container is high.
  • a great lateral load acts on the body contacted with the adjacent blow-­molded bottle-shaped container.
  • the central portion of the body is not always sufficient in mechanical strength with respect to the lateral load.
  • a diameter of a lower portion contacted with a leg is made sufficiently larger than other portions of the body so that when the blow-molded bottle-shaped containers are arranged to be adjacent to each other, the lower end portions of the bodies contact with each other. Since the lower end of the body having a large diameter is close to the leg, the lower end of the body is relatively high mechanical strength. The lower end of the body receives a lateral load exerted when a plurality of bottle-shaped containers are slidably conveyed.
  • the lower end of the body is made to have a large diameter, and the blow-molded bottle-­shaped containers stood upright and arranged to be adjacent to each other are made to contact with each other at their lower ends of the bodies, whereby a number of blow-molded bottle-shaped containers can be slidably conveyed in an upright and stabilized attitude.
  • many blow-molded bottle-shaped containers have been subjected to processing such as filling with liquids per unit time. Therefore, the lateral load acting on the lower end of the body when the containers upright and adjacent to each other are pressed and slidably conveyed becomes more powerful. Accordingly, the mechanical durability of the lower end of the body with respect to the lateral load was required to be increased.
  • the simplest countermeasure to the aforesaid demand is to sufficiently increase a wall thickness of the lower end of the body.
  • quantity of an expensive synthetic resin material required to mold a blow-molded bottle-shaped container increases by said increased portion, resulting in an increase in price of the blow-molded bottle-shaped container. Therefore, this countermeasure is not desirable.
  • the countermeasure considered to be most effective or prior art which fulfills the aforesaid demand is to control a wall thickness of the container when a blow-molded bottle-shaped container is biaxial blow-molded so that the wall thickness of the lower end of the body is made larger than the wall thickness of other body portions.
  • This conventional means is intended to increase the wall thickness of the lower end of the body to thereby increase the mechanical strength of the lower portion of the body.
  • the conventional means can obtain an effect of increasing the mechanical strength of the lower portion of the body.
  • the wall thickness of the other portions of the body is to be reduced by a portion having increased wall thickness of the lower portion of the body.
  • a principal object of the present invention is to considerably increase the mechanical strength with respect to a lateral load at a lower portion of a body of a container without reducing a wall thickness of other portions of the body and without increasing a synthetic resin material required to mold a bottle-shaped container.
  • the present invention provides a biaxially blow-molded bottle-shaped container (1) having a body (2) and a lower end (4) of the body between the body (2) and a leg (7) of the body (2), wherein a diameter of said lower end (4) of the body is the largest diameter of the container; a circumferential rib (5) is provided and externally swelled on the lower end (4) of the body; and upper and lower portions of the circumferential rib (5) comprises a rib wall (5a) in a form of a tapered wall.
  • a “main portion of a body” refers to a portion which has a function to receive and hold a content liquid.
  • the "main portion of the body” is a body portion formed with an absorbing panel wall for absorbing reduced-pressure in the container.
  • the "main portion of the body” is a portion having a substantially uniform diameter, other than a shoulder and a bottom including the leg.
  • a circumferential recessed groove having a small groove width may be interposed between circumferential ribs so that two or more circumferential ribs are disposed in parallel.
  • the circumferential rib is inflated from the lower end of the body. Accordingly, the circumferential ribs of adjacent containers contact with each other so that the blow-molded bottle-shaped containers are stood upright adjacent to each other.
  • a pressing force for press-conveyance acting on an upstream blow-molded bottle shaped container to an adjacent blow-­molded bottle-shaped containers during slidable conveyance of blow-molded bottle-shaped containers directly acts on the circumferential rib.
  • the circumferential rib adapted to directly receive the pressing force from the adjacent blow-molded bottle-shaped container is designed to have upper and lower rib walls in the form of a tapered wall, rib walls acts as a reinforcing rib. Accordingly, the pressing force exerted from the adjacent blow-­molded bottle-shaped container is received by the sufficient mechanical strength to considerably increase the mechanical durability with respect to the lateral load of the whole lower end of the body.
  • the number of rib walls serving as the reinforcing rib increases, and the mechanical durability with respect to the lateral load at the lower end of the body can be increased.
  • the reason why the width of the circumferential recessed groove positioned between the circumferential ribs where the plurality of circumferential ribs are disposed in parallel is to prevent a circumferential rib of a blow-molded bottle-shaped container from being moved onto a circumferential rib of the adjacent blow-molded bottle-shaped container to greatly incline the other blow-molded bottle-shaped container during conveyance.
  • FIG. 1 shows one example of a bottle-shaped container suitable for being provided with a circumferential rib in first and second embodiments according to the present invention.
  • a reference numeral 1 designates a biaxially blow-molded polyethylene terephthalate bottle-shaped container.
  • the container 1 has a volume of approximately 1 to 1.5 liters.
  • the container 1 includes a body 2 and a leg 7. Longitudinally extending absorbing panel walls 3 are circumferentially provided in parallel in a tubular wall portion from a center to a lower portion of the body 2. Reduced pressure is produced within the container 1 when said container 1 is cooled after the container is filled with a content liquid, sealed and heated to a high temperature at approximately 85 °C.
  • the reduced pressure is absorbed by depression and deformation of the absorbing panel wall 3.
  • a diameter of a lower end 4 of the body is largest in the container.
  • the wall thickness of the body 2 including the lower end 4 is uniformly 0.4 mm without applying wall-thickness adjusting means thereto.
  • Fig. 2 shows a contour line in a partly enlarged longitudinal section of the first embodiment in which a single circumferential rib 5 is circumferentially provided in the lower end 4 of the body.
  • the circumferential rib 5 has rib walls 5a on both upper and lower end walls in the form of a tapered tubular wall.
  • the broken line indicates a contour line of prior art.
  • the circumferential rib 5 of the present invention is not formed as a part of a curved surface smoothly continuous to the outer circumferential surface of the lower end 4 of the body as in prior art.
  • the largest diameter portion is left as the circumferential rib 5, and the diameter of portions of the lower end 4 other than the circumferential rib 5 is reduced.
  • the circumferential rib 5 in the first embodiment of the present invention has a relative large height.
  • the reason why the circumferential rib 5 is formed by leaving the largest diameter portion of the lower end 4 of the body in prior art is to prevent the diameter of the lower portion 4 of the body from being increased more than as needed by the provision of the circumferential rib 5.
  • the reason why the height of the circumferential rib 5 is relatively large is because the pressed adjacent containers 1 is always placed in contact with each other at the circumferential ribs 5 even if the upright attitude is slightly inclined.
  • Fig. 3 shows a second embodiment in which two circumferential ribs 5 are provided in parallel.
  • a height of each circumferential rib 5 is smaller than that of the circumferential rib 5 shown in Fig. 2.
  • the sum of the height of both the circumferential ribs 5 is larger than the height of the circumferential rib in the first embodiment shown in Fig. 2.
  • the test for lateral load was conducted with respect to the container in the second embodiment shown in Fig. 3 under the same conditions as noted above.
  • the distortion of the lower end 4 of the body in a radial direction was 1.09 to 1.12 mm, and the distortion can be further considerably reduced, and the occurrence of the buckling deformation can be completely eliminated.
  • the wall thickness of the lower end 4 controlled by the wall thickness controlling means was 0.55 mm which is larger by 0.15 mm than that of the container 1 according to the present invention.
  • the distortion of the lower end of the body in a radial direction was 1.13 mm, and thus the container exhibits an excellent durability.
  • the wall thickness of the body 2 other than the lower end 4 is small, the function as the whole container was deteriorated.
  • largest diameter portions of a biaxially blow-molded bottle-shaped container made of synthetic resin include an upper end of a body which is an upper end of the main portion of the body and a lower end of a body connecting with a leg of the body.
  • the diameter of the upper end of the body is equal to that of the lower end of the body.
  • Both the upper and lower ends of the body are circumferentially provided with the circumferential ribs, respectively.
  • Circumferential ribs having the largest diameter are positioned at both upper and lower end of the main portion of the body. Accordingly, when containers are pressed and placed to be adjacent to each other, the containers are pressed and contacted with each other at both upper and lower circumferential ribs. Portions of the body other than the circumferential rib which are weak with respect to the lateral load are positively prevented from being directly pressed so that said portions are depressed and deformed. The adjacent containers are pressed and contacted each other at both the upper and lower circumferential ribs. Accordingly, even if there is a container which is poor in uprightness, the container is supported at four points by adjacent containers, and therefore, the upright attitude of each container during pressing and slidable conveyance can be held at a stabilized constant state.
  • Fig. 4 shows an example of a bottle-shaped container suitable for being applied with a circumferential rib according to a third embodiment of the present invention.
  • a diameter of an upper end 8 of the body which is an upper end of a main portion of a body 2 is largest in the container, and is equal to a diameter of the lower end 4 of the body which is the lower end of the main portion of the body 2. Constructions other than the upper end 8 are same as those of the container shown in Fig. 1.
  • a single circumferential rib 5 is circumferentially provided in an externally swelled configuration as shown in Fig. 2 on the lower end 4 of the body of the container shown in Fig. 4.
  • the distortion of the upper end 8 and the lower end 4 in a radial direction when 5 Kg of lateral load is applied to the container of the third embodiment was 0.60 mm on the average.
  • the distortion of the upper end and the lower end when 5 Kg of lateral load is applied to a container not provided with the circumferential rib 5 was 1.50 mm. Accordingly, according to the third embodiment of the present invention, the distortion of the lower end 4 of the body in a radial direction can be further considerably reduced, and the buckling deformation can be completely eliminated.
  • Two circumferential ribs 5 are provided in parallel as shown in Fig. 3 on the lower end 4 of the body of the container shown in Fig. 4.
  • Two circumferential ribs 5 are provided in parallel on the upper end 8 of the body of the container shown in Fig. 4.
  • the height of each circumferential rib 5 is smaller than that of the circumferential rib 5 shown in Fig. 2.
  • the sum of the height of both the circumferential ribs 5 are larger than that of the circumferential rib 5 in the third mode of embodiment.
  • the lateral load test was conducted under the same conditions as noted above with respect to the container according to the fourth embodiment.
  • the distortion of the lower end 4 of the body in a radial direction was 0.54 to 0.56 mm.
  • the distortion can be further considerably reduced and the occurrence of buckling deformation was completely eliminated.
  • the containers according to the present invention have the construction as described above, the following effects can be obtained.
  • the circumferential rib acts as a reinforcing rib. Accordingly, the mechanical durability of the lower end of the body (and the upper end of the body) with respect to the lateral load can be considerably increased. Accordingly, the occurrence of the buckling deformation of the lower end of the body (and the upper end of the body) when the container is pressed and slidably conveyed can be prevented.
  • the circumferential rib is formed and externally swelled by bending a wall having a substantially same wall thickness of the lower end of the body (and the upper end of the body). Accordingly, it is not necessary to increase the wall thickness of the lower end of the body (and the upper end of the body) partially to be projected. Accordingly, there occurs no inconvenience that the wall thickness of the other portions of the body of the container is reduced so as to lower the fundamental function of the container as a container. Since it is not necessary that synthetic resin material is further added to partially increase the wall thickness of the lower end of the body (and the upper end of the body), the unit price of containers is not increased due to the increase in material cost for molding containers.
  • the wall thickness controlling means is not required. Accordingly, the molding operation for the container is simple.
  • Portions to be contacted with the adjacent container are specified by the circumferential ribs. Accordingly, the mode of transmission of the pressing force as the conveying force of the containers is constant, whereby the upright attitude of the containers pressed and slidably conveyed is stabilized.
