A system for preserving and capping tubes includes a compressed air reservoir for storing compressed air, a preservative reservoir containing a supply of a preservative, a nozzle in fluid communication with the compressed air reservoir and the preservative reservoir for injecting the preservative into the interior of a tube, and a capping device configured to insert a cap onto the end of the tube.

An airflow orifice adjusting device of a package thermal-shrinking oven includes at least one airflow orifice board mounted to an inside surface of a hot airflow box of the package thermal-shrinking oven and formed with series of airflow orifices, at least one track board mounted to an outside of the hot airflow box and formed with a plurality of track holes, a plurality of adjusting levers, and a plurality of airflow-blocking adjusting plates mounted to the airflow orifice board and each formed with a plurality of adjusting orifices. Each of the airflow orifices of the airflow orifice board discharges a hot airflow. The adjusting levers each have two ends that are respectively formed as a connecting portion and an operating portion. The connecting portion extends through the track holes of the track board to connect to one end of the airflow-blocking adjusting plate, so that a leftward or rightward horizontal moving operation of the operating portion of the adjusting levers causes the airflow-blocking adjusting plate to correspondingly perform a reversely directed horizontal movement in a rightward or leftward direction. The adjusting orifices of the airflow-blocking adjusting plates respectively correspond to the airflow orifices of the airflow orifice board, so that each of the adjusting orifices may completely or partially match with or completely un-match with a corresponding one of the airflow orifices of the airflow orifice board to adjust a discharging flowrate of the hot airflow and discharging of the hot airflow or not.

A method for packaging a pack commodity, including providing a support element for supporting the pack commodity. The method also includes placing a first packaging material sheet onto the support element and disposing the pack commodity on the first packaging material sheet such that a portion of the first packaging material sheet comes to lie between the support element and the pack commodity, wherein the first packaging material sheet protrudes over the pack commodity. Next, a second packaging material sheet is placed onto an upper side of the pack commodity so that the second packaging material sheet protrudes over the pack commodity. The first packaging material sheet is joined, in some regions, to the second packaging material sheet. The first and the second packaging material sheets are adhesively joined in a respective, predetermined first region, along a periphery of the support element, such that they can be separated and re-joined.

A device for shrinking a heat-shrink film placed around a palletized stack of goods includes a shrinking frame movable on a rack in vertical direction and forming an opening for the stack of goods. A shrinking device for shrinking the heat-shrink film includes a surrounding side wall, forming a shrinking space, comprising a shrink hood open downward and a cover. The shrink hood is movable in the vertical direction, and includes a blower that generates an air flow in the interior of the shrink hood. The blower includes an impeller driven by a drive. At least one air-guide section includes a nozzle on its end opposite the impeller, so that the air suctioned by the impeller from the shrinking space surrounded by the shrink hood can be reintroduce in a directed manner via the nozzle into the shrinking space surrounded by the shrink hood.

An apparatus for lidding an open container includes a housing, a feed mechanism, and a sealing assembly. The housing is configured to support a roll of a film lidding material. The feed mechanism is configured to communicate a portion of the film lidding material from the housing toward a dispense location. The sealing assembly is attached to the housing and configured to present the film lidding material for interaction with an open end of a container disposed underneath and proximate thereto. The sealing assembly is movable relative to the housing between a first position vertically above the open end of the container and a second position suitable for establishing contact between the film lidding material and the open end and enabling sealing of the film lidding material around the open end. The sealing assembly is configured for substantially vertical translation between the first position and the second position.

An airflow orifice adjusting device of a package thermal-shrinking oven includes at least one airflow orifice board mounted to an inside surface of a hot airflow box of the package thermal-shrinking oven and formed with series of airflow orifices, at least one track board mounted to an outside of the hot airflow box and formed with a plurality of track holes, a plurality of adjusting levers, and a plurality of airflow-blocking adjusting plates mounted to the airflow orifice board and each formed with a plurality of adjusting orifices. Each of the airflow orifices of the airflow orifice board discharges a hot airflow. The adjusting levers each have two ends that are respectively formed as a connecting portion and an operating portion. The connecting portion extends through the track holes of the track board to connect to one end of the airflow-blocking adjusting plate, so that a leftward or rightward horizontal moving operation of the operating portion of the adjusting levers causes the airflow-blocking adjusting plate to correspondingly perform a reversely directed horizontal movement in a rightward or leftward direction. The adjusting orifices of the airflow-blocking adjusting plates respectively correspond to the airflow orifices of the airflow orifice board, so that each of the adjusting orifices may completely or partially match with or completely un-match with a corresponding one of the airflow orifices of the airflow orifice board to adjust a discharging flowrate of the hot airflow and discharging of the hot airflow or not.

Systems, methods, and apparatuses for lidding an open container are provided herein. A system for lidding an open container includes a sealing assembly coupled to a housing and configured to dispense film lidding material for interaction with an open end of a container disposed proximate thereto. At least a portion of the sealing assembly is vertically translatable relative to the housing. The system includes at least one substantially vertical rail extending from the housing. The at least one substantially vertical rail is configured to guide the substantial vertical translation of the at least the portion of the sealing assembly.
