The second recesses are arranged between the first recesses on a rear side of the first flat element and the first recesses are arranged between the second recesses on a rear side of the second flat element such that the space remaining of the first and second recesses between the first and the second flat elements amounts to less than 50% of the space enclosed by the first and second recesses.

The present invention relates to a pouch forming apparatus comprising: a die, in which forming grooves are formed with a partition wall therebetween; and a punch member provided with a punch, which is configured to be inserted into each of the forming grooves to press the pouch film to form a pair of accommodation grooves in the pouch film, wherein the forming groove comprises a vertical space disposed above a forming groove bottom part connected to the partition wall and an inclined space connected to the vertical space and formed by providing an inner wall facing the partition wall, the inner wall defining an inclined surface .

A container thermoformed from a polymeric multilayer sheet includes a cavity for containing food. The sheet includes a polymeric interior layer positioned between (i) a polymeric outer layer of the sheet and (ii) a polymeric inner layer of the sheet that is in opposing face-to-face relation with, and at least partially defines, the cavity of the container. The interior layer includes post-consumer recycled polymeric material. The sheet includes a polymeric barrier layer positioned between the interior layer and inner layer. The barrier layer restricts inward passage of at least some of any gasses originating from the post-consumer recycled polymeric material.

A multi-sheet component for a utility vehicle that includes at least one gap between at least two of the sheets, thereby providing a component that enhances worker safety by increasing component stiffness and reducing component thickness. The component is manufactured through multi-sheet thermoforming and uses a conical frustum corrugation to increase stiffness.

A mold which can improve an appearance of a molded body is provided. A mold includes a cavity, the mold being capable of subjecting a resin sheet under reduced pressure suction via a plurality of reduced pressure suction holes thereby shaping the resin sheet to follow a shape of an inner surface of the cavity; wherein: the inner surface includes a base surface and a plurality of island-like concave portions provided in the base surface; and a concave portion reduced pressure suction hole index defined by an in-concave reduced pressure suction hole ratio divided by a concave portion area ratio is 0.5 or lower.

A thermoforming machine is provided having at least one frame member and a thermal regulator. The thermal regulator is provided in heat transfer relation with one of the at least one frame member configured to control temperature of the one frame member to mitigate thermal deformation of the frame member. A method is also provided.

A fluid-filled chamber may include a pair of polymer layers that define a plurality of subchambers and a web area. The subchambers are protruding portions of the polymer layers that enclose a fluid, and the web area is portions of the polymer layers that are located between the subchambers and lay adjacent to each other. The subchambers may have greater thickness than the web area. A perimeter bond joining the polymer layers and extends around a periphery of the chamber. In addition, a plurality of interior bonds join the polymer layers and extend around the subchambers, which may seal the fluid within the subchambers.

An electrochemical cell includes a housing, and an electrode assembly disposed in the housing. The electrode assembly comprises a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode. The housing is formed of a first case half and a second case half. Each case half is formed of a metal foil laminate material and includes a wedge-shaped central recess that is surrounded by a flange. The flange of the first case half is joined to the flange of the second case half along a seal line that surrounds the respective central recesses. The central recesses cooperate to define an interior space of the housing that contains the electrode assembly, and the interior space has the shape of a rectangular prism. The seal line extends along a diagonal of a side of the rectangular prism. A method of forming the housing is described.

A rigid connecting device for connecting the upper and lower surfaces inside an oil tank includes a connecting rod. The upper and lower sides of the connecting rod are each provided with a connecting end surface. The connecting end surface is provided with material-passing hole. The outer surface of the rigid connecting device is covered with high-density polyethylene. The upper and lower surfaces of the oil tank are connected by a connecting rod, and such arrangement is locally applied to areas where the rigidity of the oil tank is poor, so there are more effective space. The part of the rigid connecting rod contacting with the oil fuel is made of high-density polyethylene, so the requirements of strength and anti-corrosion can be satisfied.
