Resin-molded articles, to which such advantages as strength, rigidness and light weight are secured thanks to kneading with fibers, and which has excellent surface characteristics such as smoothness of the surface and beauty in the appearance, and resistance against weather, ultraviolet rays and light are provided.

A method includes positioning a first polymer sheet on a substantially first flat surface of a tool, positioning a second polymer sheet on the first polymer sheet, and moving a second substantially flat surface of the tool into contact with the second polymer sheet. The method also includes maintaining a gap between the first polymer sheet and the second polymer sheet at a predetermined area and heating one of the two substantially flat surfaces of the tool to heat one of the first polymer sheet and the second polymer sheet. The method further includes joining the first polymer sheet and the second polymer sheet together at locations outside of the predetermined area to define a peripheral bond of the chamber.

A method of manufacturing a fuel tank includes: passing a hollow molten resin projection, that projects-out in a wall-thickness direction and is formed at a molten resin sheet that becomes a tank structural member structuring a tank main body, through a mounting hole of a part-to-be-mounted that is placed on the molten resin sheet; and pressurizing the molten resin projection from an inner side, and causing at least a portion of the molten resin projection to jut-out to a peripheral portion of the mounting hole of the part-to-be-mounted.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

The present invention relates to a sensing device (10) designed for being applied on a first flap (11) and on a second flap (12) of an opening (13) arranged in a wearable item (14). The sensing device (10) comprises: a triggering element (20) arranged on the first flap (11) of the opening (13) and comprising an activating component (23); a switch element (30) arranged on the second flap (12) of the opening (13) and comprising a sensing component (33); the sensing component (33) being designed for emitting an electrical output signal when it is put in a predetermined mutual position with respect to the activating component (23). According to the invention the triggering element (20) is provided with at least one alignment component (22; 22A, 22B) designed for interacting with a corresponding alignment component (32; 32A, 32B) of the switch element (30) so as to autonomously and automatically put in said predetermined mutual position the activating component (23) and the sensing component (33) when the first flap (11) is drawn close to the second flap (12), or viceversa. The invention also relates to a closure device comprising said sensing device (10) and to a method for manufacturing said sensing device (10).

A container capable of suppressing the unexpected opening of a pair of upper walls including a first side wall and a second side wall facing each other; a third side wall provided therebetween; a first upper wall and a second upper wall; and a locking member. The first side wall and the second side wall face each other. The first upper wall and the second upper wall are configured to be rotatable with respect to the first side wall and the second side wall, respectively. The locking member includes a fixed portion and an engagement portion, the fixed portion being fixed to the third side wall, the engagement portion being engaged with at least one of the first upper wall and the second upper wall to prevent the first upper wall and the second upper wall from opening.
