Abstract: A synthetic resin bottle is provided with a shape that improves rigidity and strength in a lateral direction, without increasing the cost of material to thicken the bottle wall. The synthetic resin bottle is provided at a low cost in such a way that the bottles can be used smoothly on the carrier line, in vending machines, and in storage in stacks with no deformation. The bottles are capable of performing a vacuum-absorbing function enough to be used in hot filling. Multiple pillar sections in a projected strip-like shape are disposed on the body of a synthetic resin bottle, the pillar sections being inclined spirally at a uniform angle of gradient (?) relative to a central axis of the bottle and disposed in parallel to one another, so that the cylindrical body wall is prevented from being deformed by a pressure force acting in a lateral direction.

Abstract: The technical problem to be solved by this invention is to design a bottle shape that improves the bottle rigidity and strength in the lateral direction, without increasing the cost of material required to thicken the bottle wall. The object of this invention is to provide a synthetic resin bottle at a low cost in such a way that the bottles can be used smoothly on the carrier line, in the vending machines, and in storage on the stacks with no deformation, and are capable of performing a vacuum-absorbing function enough to be used in hot filling. Multiple pillar sections in a projected strip-like shape are disposed on the body of a synthetic resin bottle, wherein the pillar sections are inclined spirally at a uniform angle of gradient (?) relative to central axis of the bottle and disposed in parallel to one another, so that the cylindrical body wall is prevented from being deformed by the pressure force that acts in a lateral direction.

Abstract: A round bottle that gives an overall impression of a slim body, while maintaining a basic shape of the round bottle and a vacuum absorbing function. An object is to provide a round synthetic resin bottle having a differentiated shape not found in conventional art. This involves narrowing down a diameter of the body in a tapered manner toward a middle height position of the body to form a tapered portion at either one of an upper end or a lower end of the basically cylindrical body and thus to form a waist portion in a narrowest part of this tapered portion, and forming a plurality of dented vacuum absorbing panels in a height range lying next to the waist portion of the body and in a configuration that each of the panels is disposed in parallel in a circumferential direction and dented by a stepped portion surrounding each panel.

Abstract: A technical problem of this invention especially in the case of large-size bottles is to form a grip, without changing the bottle shape to a large extent, so that the body can be firmly held. The object of this invention is to provide a synthetic resin square bottle that can be used reliably because the bottle can be held firmly with a hand. A major means of solving the problem is a synthetic resin square bottle comprising a body having a rectangular shape in a plane cross-section and a groove-like waist portion disposed at a middle height of the bottle, wherein a pair of recessed portions for use as finger stops are formed in respective long side walls of said rectangular body over a predetermined area ranging from said waist portion downward to ensure that a plural number of fingers can be placed in at least one recessed portion for a finger stop purpose, and wherein a grip for holding the bottle is formed from both the pair of recessed portions and the waist portion.

Abstract: A detection chip comprises a substrate and a well-shaped reaction portion formed in the substrate, in which the well-shaped reaction portion comprises a bottom portion having a planar shape and a side portion the width between which is widen from the bottom portion toward an opening portion.

Abstract: A bottle-shaped synthetic resin container (1) includes a body portion (3), and a circumferential groove (10) extending along an outer surface of the body portion (3). The circumferential groove (10) is defined by a groove bottom wall (11) and groove side walls (12a, 12b) extending from the groove bottom (11) to the outer surface of the body portion (3). At least one of the groove side walls (12a, 12b) extends substantially linearly, as seen in a longitudinal-sectional plane including a center axis (A) of the body portion (3), and forms an angle (?, ?) of not more than 20° relative to a reference line (L) perpendicular to the center axis (A) of the body portion (3) in the longitudinal-sectional plane of the container (1).

Abstract: In a bottle-shaped synthetic resin container having a body part of substantially rectangular tubular shape, groove ribs, having a comparatively wide vertical groove form, are depressingly provided at the centers in the width direction of flat wall portions of shoulder lower end parts, which are portions of a shoulder part that connect with the body part, to make these portions higher in rigidity and difficult to deform and, even when a deformation occurs, prevent the deformation from becoming a permanent deformation. Safe handling of the container is thus promoted, especially for the stacked storage of containers in a sideways-laid orientation.

Abstract: The gas-venting groove or grooves are formed, while leaving a part of the thread ridge up to a certain height, as the vertical degassing paths in the thread ridge carved on the outer surface of the round neck wall and the entire neck is whitened by the thermal crystallization. This thermal crystallization is conducted under the condition that the neck is prevented from undesired deformation caused by uneven resin flow state. Thus, the object of this invention is to provide a highly safe neck that can be used widely in the field of heat-resistant containers, pressure-tight containers, and heat-resistant and pressure-tight containers.

Abstract: The technical problem of this invention is to eliminate the need to use deformable panel walls and to find the body of a shape that no false deformation, such as dented deformation, takes place in a portion of the body due to the hot filling of the contents or the reduced pressure created by the treatment of retort-packed foods. The object of this invention is to obtain a bottle that can inhibit the deformation caused by reduced pressure, has a high buckling strength, and is good in outer appearance. As the solution, there is provided a biaxially drawn, blow-molded bottle made of a synthetic resin, in which the surface rigidity of the wall of body is set in such a manner that a part of the body wall cannot become dented inward under a reduced inner pressure of at least 350 mmHg (46.7 kPa).

A manufacturing method can manufacture such a bottle-shaped container. A lightweight bottle-shaped container made of synthetic resin and formed by biaxially-oriented blow-molding, characterized in that a wall thickness is increased to 109% or more of an average wall thickness of blow-molded pad of the wall at an infection point between a portion having a transversal cross sectional area and a portion having a different transversal cross sectional area in a cylindrical wall. The wall is thicker between the heel and the bottom, or at the waist, at the recessed rib, or at the projection.
