Definitions
- the present invention relates to a plastic bottle including a mouth, a shoulder gradually increasing in diameter toward the bottom from the mouth, and a body continuous with the shoulder.
- plastic bottles which are displayed in a cooled state or at normal temperature are used as plastic bottles for filling beverages.
- the drink of normal temperature may be filled and it may be used as it heats at the time of display.
- the internal pressure of the bottle is filled by the temperature change by the heating at the time of display. It will rise more than time.
- the bottle which provided the panel for pressure absorption in the shoulder part and the trunk part is disclosed by Unexamined-Japanese-Patent No. 2016-132500 (patent document 1), According to this bottle, this shoulder part and The body panel is designed to absorb the increase in internal pressure due to heating after filling.
- the plastic bottle according to the present invention is It is a plastic bottle provided with a mouth, a shoulder gradually expanding in diameter toward the bottom direction from the mouth, and a body continuous with the shoulder,
- the shoulder is provided with at least one panel which is recessed inwardly.
- the bottom surface of the panel is formed in a curved surface that is convex inward,
- the depth from the plane passing through the upper and lower ends of the panel to the deepest portion of the bottom surface of the panel is 1 mm to 7 mm.
- the panel by disposing the panel having the curved surface which is convex toward the inside, the panel can be largely moved outward when the pressure inside the bottle is increased, and the shoulder portion is increased.
- the pressure absorption effect can be effectively enhanced.
- the depth by setting the depth to 1 mm to 7 mm, it is possible to effectively enhance the pressure increase absorption effect in the shoulder portion. That is, if the depth is less than 1 mm, the intensifying absorption amount is insufficient, and if the depth is more than 7 mm, the panel becomes difficult to move and the intensifying absorption becomes difficult.
- pillars be provided between the side edges of the adjacent panels.
- a boundary between the column portion and the panel is formed in an arc shape.
- the panel is connected to the body portion, and a boundary between the body portion and the panel is connected in an arc shape.
- the boundary between the column and the panel and the boundary between the body and the panel are arc-shaped, so that the panel is more likely to move outward during pressure increase than when the boundary is angular. Become.
- the panel is formed in a triangular or trapezoidal shape.
- the triangular or trapezoidal shape of the panel allows the panel to be widely provided on the shoulder.
- the panel can be moved more easily and the panel area can be wider than a rectangular panel.
- the circumferential surface of the body portion is formed as a smooth surface without unevenness.
- the body can be a smooth surface without panels, and the design effect can be enhanced.
- the plastic bottle is preferably a plastic bottle for heating.
- the pressure increase can be absorbed more effectively by the shoulder portion, the problem due to the pressure increase inside the bottle can be effectively avoided even as a plastic bottle for heating as in this configuration.
- FIG. 3 is a cross-sectional view taken along the line III-III in FIG. It is IV-IV sectional drawing of FIG.
- the plastic bottle 1 according to the present embodiment has a mouth 2 as a liquid pouring spout, a shoulder 3 which is continuous with the mouth 2 and which gradually expands in diameter toward the bottom. It comprises a cylindrical body 4 continuous with the shoulder 3 and a bottom 5 which is the bottom of the plastic bottle 1. And the plastic bottle 1 which concerns on this embodiment is for heating, and the panel 31 provided in the shoulder part 3 has the characteristics.
- the configuration of the shoulder 3 will be described in detail.
- each panel 31 is provided at equal intervals and in the same shape on the shoulder portion 3.
- the bottom face 31a of each panel 31 is formed in the curved surface which becomes convex toward a bottle inward.
- the curved surface which is convex toward the inside of the bottle enables the panel 31 to move largely outward when the pressure inside the bottle is increased.
- the panel 31 extends perpendicularly to the circumferential direction.
- the depth D (see FIG. 4) from the plane P passing through the upper and lower ends 31c, 31c of the panel to the deepest part of the bottom surface 31a of the panel 31 is 1 mm to 7 mm. If the depth D is less than 1 mm, the intensified absorption amount is insufficient, and if the depth D exceeds 7 mm, the panel becomes difficult to move and the intensified absorption becomes difficult.
- the depth D is more preferably 2 mm to 6 mm, and further preferably 3 mm to 5 mm.
- pillars 32 are provided between the side 31 b of the adjacent panels 31.
- the boundary between the column portion 32 and the panel 31 is formed in an arc shape, and the panel 31 can be easily moved outward during pressure increase as compared with the case where the boundary between the column portion 32 and the panel 31 is angular.
- the panel 31 is connected to the body 4, and the boundary between the body 4 and the panel 31 is formed in an arc shape.
- the panel 31 can be easily moved outward at the time of pressure increase, as compared with the case where the boundary between the body 4 and the panel 31 is angular.
- the panel 31 is formed in a trapezoidal shape.
- the panel 31 can be widely provided on the shoulder 3, and the pressure-increasing absorption effect in the shoulder 3 is enhanced.
- the panel is more easily moved outward at the time of pressure increase as compared with the rectangular panel, and the panel area can be wider.
- the plastic bottle 1 having the above-described configuration has the pressure-increasing effect enhanced by the shoulder portion 3, and without providing the body 4 with the structure having the pressure-increasing function, the pressure increase inside the bottle at the time of heating It is possible to absorb. So, in this embodiment, in order to absorb a pressure increase in the shoulder part 3, the characteristic structure which comprises a surrounding surface in the smooth surface without an unevenness
- a bottle in which the panel itself is not provided in the shoulder (2) a bottle in which four panels are provided in the shoulder but the bottom of the panel is flat, (3) the bottom is inward of the bottle
- the bottle with 4 panels on the shoulder that is formed on a curved surface that is convex toward the bottom is a bottle with a depth of 3 mm at the deepest part of the panel, and in the bottle of (4), (3)
- the plastic bottle 1 can be integrally molded by, for example, a thermoplastic resin such as polyethylene, polypropylene or polyethylene terephthalate as a main material by a stretch molding method such as biaxial stretch blow molding.
- the capacity of the plastic bottle 1 is not particularly limited, and can be about 200 ml to 2 liters, such as 280 ml, 350 ml, 500 ml, etc., which are generally in circulation.
- the liquid to be filled in the plastic bottle 1 is not particularly limited. For example, drinking water, tea, fruit juice, coffee, cocoa, soft drinks, alcoholic beverages, milk drinks, beverages such as soups, and liquids such as sauces and soy sauce Seasoning etc. are mentioned.
