Definitions

  • the present invention relates to a plastic bottle including a spout portion, a shoulder portion whose diameter progressively increases from the spout portion toward a bottom face, and a body portion continuous with the shoulder portion.
  • plastic bottles for charging beverage therein there have been employed not only plastic bottles that are displayed under a cooled state or at a room temperature, but also plastic bottles for heating that are displayed under a heated state.
  • the plastic bottles for heating are sometimes used in such a manner that the bottles are charged with beverage at the room temperature and heated at the time of displaying. In such case, due to change of temperature by heating at the time of displaying, the inside pressure of the bottle rises from that at the time of charging.
  • Patent Document 1 discloses a bottle having pressure absorbing panels in its shoulder portion and its body portion. With this bottle, thanks to the panels in the shoulder portion and the body portion, a rise of the inside pressure due to heating at the time of charging can be effectively absorbed.
  • Patent Document 1 JP2016-132500A
  • a plastic bottle according to the present invention comprises:
  • the panel is allowed to move by a large amount toward the outer side at the time of rise of pressure inside the bottle, so that the increased pressure absorption effect in the shoulder portion can be effectively enhanced.
  • this also can effectively enhance the increased pressure absorption effect in the shoulder portion. Namely, if the depth were smaller than 1 mm, the resultant increased pressure absorption amount would be insufficient. Conversely, if the depth were greater than 7 mm, this would make movement of the panel difficult, thus making the increased pressure absorption difficult.
  • a pillar portion is provided between lateral sides of the adjacent panels.
  • the shoulder portion there are provided three or more of the panels.
  • each panel needs not to be too large, so that the movements of the panels at the time of pressure increase are facilitated.
  • a border between the pillar portion and the panel is formed arcuate.
  • the panel is connected to the body portion and a border between the body portion and the panel is formed arcuate.
  • the panel is formed triangular or trapezoidal.
  • the panel as the panel is formed triangular or trapezoidal, the panel can be provided over a large area on the shoulder potion. Moreover, in comparison with a square-shaped panel, the above arrangement facilitates the panel movement and allows increase of the panel area also.
  • the circumferential face of the body portion is formed as a flat smooth face without unevenness.
  • pressure increase can be effectively absorbed by the shoulder portion, so the body portion can be formed as a flat smooth face having no "panel", so that the aesthetic effect can be increased.
  • the plastic bottle is a bottle to be heated.
  • plastic bottle relating to the present invention pressure increase can be effectively absorbed by the shoulder portion.
  • this bottle is designed as a plastic bottle for heating, disadvantageous effect to due to increase of the inside pressure of the bottle can be effectively avoided.
  • a plastic bottle 1 relating to this embodiment includes a spout portion 2 as a spout or outlet for pouring liquid, a shoulder portion 3 formed continuous with the spout portion 2 and having a diameter which progressively increases toward the bottom face, a cylindrical body portion 4 continuous with the shoulder portion 3, and a bottom portion 5 constituting the bottom of the plastic bottle 1.
  • this plastic bottle 1 relating to the instant embodiment is designed for heating (to be heated) and is characterized by panels 31 provided in the shoulder portion 3. Next, the arrangement of the shoulder portion 3 will be discussed in details.
  • a bottom face 31a of each panel 31 is formed as a curved face which is formed convex toward the bottle inner side.
  • the panel 31 is allowed to move largely toward the outer side at the time of pressure inside the bottle. Further, the panel 31 is configured to extend perpendicular to the circumferential direction.
  • a depth D (see Fig. 4 ) from a plane P extending through upper and lower opposed ends 31c, 31c of the panel 31 to the deepest portion of the bottom face 31a of the panel 31 is arranged to range from 1 mm to 7 mm. This is because if the depth D were smaller than 1 mm, the increased pressure absorption amount would become insufficient; whereas if the depth D were greater than 7 mm, this would make the panel movement difficult and make increased pressure absorption difficult also.
  • the depth D ranges from 2 mm to 6 mm more preferably and ranges from 3 mm to 5 mm even more preferably.
  • a pillar portion 32 is provided between lateral sides 31b of adjacent panels 31, a pillar portion 32 is provided between lateral sides 31b of adjacent panels 31, a pillar portion 32 is provided. With provision of such pillar portion 32, it is possible to prevent movements of the adjacent panels 31 from interfering with the respective panels each other. Further, the border between the pillar portion 32 and the panel 31 is formed arcuate. In comparison with an arrangement of the border between the pillar portion 32 and the panel 31 being formed angular, the movement of the panel 31 toward the outer side at the time of pressure increase is made easier. Moreover, the panel 31 is connected to the body portion 4 and the border between the body portion 4 and the panel 31 is formed arcuate also. With this arrangement, in comparison with an arrangement of the border between the body portion 4 and the panel 31 being formed angular, the movement of the panel 31 toward the outer side at the time of pressure increase is made easier.
  • the panel 31 is formed trapezoidal. With this, the panel 31 can be provided over a large area on the shoulder portion 3, thus enhancing the increased pressure absorption effect of the shoulder portion 3. Further, in comparison with a panel having a square shape, the movement of the panel toward the outer side at time of pressure increase is facilitated and the area of the panel can be increased also.
  • the increased pressure absorption effect is enhanced by the shoulder portion 3, so that increased pressure inside the bottle at the time of heating can be absorbed effectively, without providing the body portion 4 with an arrangement for increased pressure absorption.
  • the shoulder portion 3 since the shoulder portion 3 absorbs increased pressure, it is possible to employ a characteristic arrangement of constituting the body portion 4 of a flat smooth face having no unevenness, so that the aesthetic effect can be enhanced.
  • bottles which are different only in the arrangements of their shoulder portions namely, (1) a bottle having no panels in the shoulder portion, (2) a bottle having four panels in the shoulder portion and a bottom face formed as a flat face, (3) a bottle having four panels in the shoulder portion and a bottom face formed as a curved face convex toward the inner side and a 3 mm depth at the panel deepest portion, (4) a bottle arranged similarly to the bottle of (3), except in that the panel deepest portion has a depth of 4 mm, and (5) a bottle arranged similarly to the bottle of (3), except in that the panel deepest portion has a depth of 5 mm.
  • the plastic bottle 1 relating to the instant embodiment can be made by using a thermosetting resin such as polyethylene, polypropylene, polyethylene terephthalate, etc., as its main material and formed by a stretch molding technique such as the biaxial stretch blow molding technique.
  • the capacity of the plastic bottle 1 is not particularly limited, it may range from 200 ml to 2 liters approximately, such as 280 ml, 350 ml, 500 ml which are commonly employed in the market.
  • the liquid to be charged in the plastic bottle 1 is not particularly limited, it may be drinking water, tea, juice, coffee, cocoa (chocolate), soft drink, hard (alcoholic) drink, milk-based drink, liquid food such as soup, liquid seasoning or condiment such as Worcester sauce, soy sauce, etc.
  • the present invention is applicable to a plastic bottle for heating for instance.
