It is described hereby a temperature indicator device (1), to be used on containers holding beverage, preferably metallic cans, composed of a thermo sensitive and/or biodegradable material.
摘要:
A plastic container having a base portion (20) adapted for vacuum pressure absorption. The base portion including a contact ring (34) upon which the container is supported, an upstanding wall (44) and a central portion (36). The upstanding wall being adjacent to and generally circumscribing the contact ring. The central portion being defined in at least part by a central pushup (40) and an inversion ring (42) which generally circumscribes the central pushup. The central pushup and the inversion ring being moveable to accommodate vacuum forces generated within the container.
摘要:
Beverage container (1) made of plastic material and particularly of PET, characterized in that said container has at least a region revealing the tampering 10 action, said region revealing the tampering action having a first profile or a first shape of a corresponding portion of the container wall and a second profile or a second shape of said portion of the wall, the first profile or the first shape of said wall 15 portion being stable under predetermined pressure conditions with the filled container corresponding to the normal bottling condition, whereas said wall portion passes from said first profile or said first shape to said second profile or said second shape when 20 normal bottling conditions and particularly filling pressure conditions upon the bottling are temporarily and/or permanently modified.
摘要:
A bottle having a base including an inwardly and upwardly projecting flexible surface within a generally continuous seating ring has a generally cylindrical wall extending upward from the base. A plurality of annular inwardly projecting, and vertically flexible rings extend about the cylindrical wall perimeter interrupting the cylindrical wall. At least one of rings projects inwardly more than some others of the rings to achieve a sidewall crush resistance that is at least as great as comparable bottles with thicker sidewalls. A shoulder portion, including a plurality of vertical ribs separating a plurality of vacuum responsive panels, extends upward from the cylindrical wall to a neck leading to a cappable opening. The vertical flexibility of the bottle sidewall reduces the amount of flexing required in the shoulder panels and base to accommodate the same vacuum development, and enhances the total amount of post capping vacuum development that can be accommodated by the bottle as a whole.

A blow-molded bottle has a flexible concave perimeter surface (96) extending between an upper peripheral margin (92) projecting outward from the bottle neck and an outwardly protruding ring (94) located above the sidewall upper margin. The flexible concave perimeter surface is specially dimensioned to respond to the presence of a vacuum within the bottle by forming linear segments between the upper peripheral margin and the outwardly protruding ring. The average radius of the vertical mid-point of the concave perimeter surface is generally greater than (3/π) (sin π/3) (R 1 + R 2 ), and less than (6/π) (sin π/6) (R 1 + R 2 ), where R 1 is the outermost radius of the upper peripheral margin, and R 2 is the radius of the outwardly protruding ring. The vertical midpoint radius of the flexible concave perimeter surface measured from the vertical axis can be made to vary by between one and five percent at between three and five positions around the perimeter.

The invention relates to a pressurized can, such as an aerosol can, having a bottom comprising a panel connected via a countersink and a foot to the can body wall, which bottom has a panel with a substantially non-concave form.
摘要:
A gas-venting groove as a path for gas in an up/down direction is formed on a thread provided on the outer periphery of a tube wall of a mouth tube portion with part of the thread left without forming the groove. When the entire tube mouth portion is whitened by thermal crystallization with abnormal deformation caused by unevenness of fluidity of resin prevented from occurring, a highly safe mouth tube portion broadly adaptable for products including heat resistant containers, pressure resistant containers, and heat/pressure resistant containers is obtained.
摘要:
The synthetic resin container according to the present invention has a waist dividing a container main body portion into upper and lower parts, wherein the waist is formed on an annular groove surrounding the main body portion to as to be convex toward the interior of the container. The annular groove has reinforcing ribs with a level higher than a groove bottom of the annular groove and lower than the surface of the main body portion. The container main body portion includes reinforcing lateral ribs each having a concave portion which is positioned at the same level as a surface of the container, which or forms a slight step relative to the surface of the container. The main body portion has a plurality of ridges converging toward the associated central convergent point, respectively, thereby defining multi-faceted concave walls inclined toward the associated convergent points, respectively.
