Bag-sealing apparatus is provided for heat-sealing a bag. The apparatus has a heater arrangement operable to apply heat to heat-seal an open end of the bag. A bag detector detects the location of the bag relative to the heater arrangement. The heater arrangement is formed of plural heater portions. The heater arrangement is operable such that only the or each heater portion that overlies the bag as detected by the bag detector is caused to operate to apply heat to the bag.

Systems and methods for making an insulating container having at least one cavity in a lid insulating structure or base insulating structure and having at least one vacuum insulated panel disposed within the at least one cavity.

The present disclosure relates to removing residual air in a packaged product. In particular, the present disclosure is directed to a residual air reduction device and to methods of using such device to reduce the amount of residual air in a packaged product. Such a device is employed during the manufacturing process to release air trapped in a product matrix and/or in a head space of the package as the package contacts the device. In some embodiments, the device and methods of the disclosure are useful in reducing residual air in a pouch package by at least 5% in comparison to a pouch package manufactured without use of the device and/or methods described herein.

An electrical vacuum-pumping device includes a primary structure body, an upper lid, an electrical vacuum pump, a power source, and a suction nozzle. The primary structure body includes an upper body board and a lower body board which are fastened with each other, and in which an accommodating space is provided. The lower body board is provided with a suction hole for communicating with ambient atmosphere. The electrical vacuum pump is provided with a vacuum-pumping mouth, and is arranged in the accommodating space, and is electrically connected with the electrical vacuum pump. The suction nozzle is fixedly arranged underneath to the lower body board. When in a state of use, the suction nozzle can engage directly with an impermeable cup or a joint at one's option; or engage an object to be vacuum-pumped and then attach the same to the object to be vacuum-pumped.

Disclosed is a vacuum apparatus that is not complicated in construction, does not require two receptacle bodies, and is improved in vacuum efficiency. The vacuum apparatus includes a cylinder member provided with a guide shaft disposed in the central area of the inner space thereof, and a piston module including a separating and opening/closing unit and a hollow rod unit with a guide bore in the inside thereof extending downward from the central area of the separating and opening/closing unit. The piston module is fitted in the inside of the cylinder member to separate the inner space of the cylinder member into an upper first space and a lower second space, and provided with a first O-ring to open/close the first space and the second space in relation to each other while being moved vertically according to a moving direction in relation to the cylinder member.

A method for increasing the dielectric withstand strength in the enclosure E of an electrical apparatus, this method consisting in placing in the enclosure a dielectric material in liquid or solid form, then in bringing this material to a temperature and/or a pressure allowing for its total or partial evaporation in the enclosure. This method includes a device for retaining the abovementioned material in its container during the handling allowing the placement of the container in the enclosure E, and a device for inducing the evaporation of this material at a certain moment after this placement in the enclosure E and for allowing the dispersion of the gases resulting from this evaporation in the enclosure E.
