  • the present invention relates to an aseptic filling bottle having a mouth, a shoulder, a trunk, and a bottom.
  • plastic bottles filled by the aseptic filling method may have low heat resistance, and thus can be made thin and lightweight bottles.
  • Patent Document 1 discloses a bottle that suppresses the buckling of the bottom by providing a dome-shaped recess that retracts inward at the center of the center of the bottom. Proposed.
  • ⁇ Plastic bottles filled with contents may be stored not only at room temperature or refrigerated, but also warmed or frozen by warming or freezing the contents.
  • the contents expand due to warming or freezing, which causes a problem of buckling at the bottom.

  • the height of entry into the bottle inside the dome side peripheral edge of the central part is formed in a state where it is higher than half of the height from the ground contact part to the boundary between the trunk part and the bottom part,
  • the depth of the concave groove portion corresponding to the center position in the radial direction of the ground contact portion is 5.0 mm to 10.0 mm.
  • the inventor does not make the center part into a dome shape with its center protruding into the inside of the bottle, but keeps the dome shape at the center while maintaining the entire center part from the peripheral part of the dome part to the grounding part. It has also been found that the strength of the bottom of the bottle can be further enhanced by adopting a configuration that enters the inside of the bottle as it goes radially inward. The inventor further increases the maximum entry height of the central portion, i.e., the entry height to the inside of the bottle at the peripheral edge of the dome-shaped portion, so that the strength is higher than half the height of the bottom portion. It was also found that the effect of strengthening can be further enhanced.
  • the strength of the bottom can be reinforced by the concave groove formed radially from the central portion, and the depth of the position corresponding to the central position in the radial direction of the grounding portion of the concave groove is 5.0 mm to 10. Since it is 0 mm, the strength of the bottom can be further reinforced, and even the contents that are easily expanded by freezing can effectively suppress the buckling of the bottom. Furthermore, by setting this depth, even when the container is heated, buckling at the bottom can be suppressed.
  • the central portion is formed in an arc shape.
  • the central portion is applied to the central portion as compared with the case where the central portion is formed in a straight line from the grounding portion to the dome portion side peripheral portion. Since the pressure is made uniform, the strength of the bottom can be increased more effectively. Thereby, the buckling of the bottom part in frozen storage can be suppressed more effectively.

  • the concave groove portion that reinforces the strength of the bottom portion is formed long from the dome portion to the peripheral portion, the strength of the bottom portion can be further reinforced.
  • the body portion is formed with at least one concave rib that circulates around the peripheral surface thereof.
  • the volume expansion of the contents in the frozen storage can be absorbed to some extent by the concave rib provided in the body portion, so that the force applied to the appropriate part by the volume expansion can be reduced, and the frozen storage

  • the shoulder portion 4 is a portion that gradually increases in diameter toward the bottom surface continuous with the mouth portion 2, and has a shape obtained by combining polygonal panels having various shapes.
  • the trunk 4 is a cylindrical part that is continuous with the shoulder 3.
  • the bottom portion 5 is a portion of the bottle body portion 3 that gradually decreases in diameter toward the bottom surface of the bottle body portion 3. That is, in this embodiment, the position of the boundary between the body part 5 and the bottom part 6 is a position in the height direction in which the bottle main body part 3 starts to shrink in diameter toward the bottom surface.
  • the bottle 1 is a bottle used in an aseptic (sterile) filling method in which a liquid is filled into the bottle in a sterile state.

  • the bottle 1 Since the bottle 1 according to the present embodiment is configured to withstand the expansion of the filling when the filled liquid is frozen as will be described later, the contents to be filled in the bottle 1 are, for example, minerals
  • Non-carbonated beverages that can be stored frozen, such as water, tea, soft drinks, or fruit juices, are particularly suitable. However, it can also be suitably used for foods such as carbonated drinks and sauces.
  • the body part 5 is a straight body type, and the body part 5 is formed with a plurality of concave ribs 7 that circulate around the peripheral surface thereof.
  • the concave rib 7 has a concave shape on the inner side in the radial direction (the direction toward the central axis X of the bottle 1 and along the horizontal direction), and the width and depth of each concave rib 7 are substantially the entire circumference. It is formed uniformly.

More preferably, at least one is formed at the lower part of the body part, and a plurality is formed at the upper part of the body part. If at least one bottle is formed at each of the lower part of the body and the upper part of the body, the volume expansion of the inner solution at the time of freezing can be easily extended vertically upward of the bottle 1, so that the bottle 1 is straight and freestanding without tilting. Yes, and there is no deformation or rupture of the bottle. Moreover, as shown in FIG. 1, the concave rib 7 should just be a concave shape inside radial direction, and the concave shape should just be formed over the perimeter.
