PURPOSE:To obtain a device for making the inside of a drink pack vacuumed in a short time, by vibrating a pack on a conveyer with the use of a vibration loading belt to agitate the contact and gas in the pack, and by promoting gas absorption to make the inside of the pack vacuumed in an on-one line system. CONSTITUTION:A pair of frames 2 are arranged above a conveyer 1 on which a pack P is carried, so that they forms therebetween a space for the pack P, and are provided thereto pulleys. An eccentric roller 5 is rotatably fitted on the lower end of the shaft of each pulley. The pulleys are wounded thereon with timing belts 6a, 6b by way of a drive pulley 8 and a tension pulley 9. Further, rollers 10, 11 are arranged at both ends of the rows of the eccentric rollers 5, and are wounded thereon with vibration loading belts 16. When the belts 6a, 6b are driven, the eccentric rollers 5 vibrates the loading belts 16, and therefore, the pack P passing through between the belts 16 are laterally vibrated while it travels, and therefore, it is possible to effectively promote vacuum making process.
