A computer server includes processor and memory hardware. The processor hardware executes instructions including parsing a hypertext transfer protocol (HTTP) request from a first user agent to identify a first data object matching a set of characteristics and generating a new data element based on the HTTP request. The instructions include, in response to the first data object being present: extracting a first set of serialized data elements and serializing them with the new data element to generate a second data object. The instructions include, in response to the first data object being absent and a user associated with the first user agent being identifiable: determining a second set of serialized data elements based on an identity of the user, and serializing them with the new data element to generate the second data object. The instructions include transmitting an HTTP response including the second data object.

A method for packaging one or more tobacco-filled boxes (13) in a plastic bag (21) comprises the following steps of—placing the box in a vacuum chamber (3, 5) through an input (7),—closing the vacuum chamber, then evacuating the vacuum chamber and thereafter creating an over-pressure nitrogen atmosphere in the vacuum chamber—putting a bag open at one end around a rectangular guide profile (19) open at both ends, where the other, closed, end of the bag shuts off one of the ends of the rectangular guide profile,—positioning the rectangular guide profile with the end not shut off by the bag in front of a shut off output (9) of the vacuum chamber and coupling the rectangular guide profile in a gas-tight manner to the output of the vacuum chamber,—opening the output of the vacuum chamber and guiding the box into the bag via the rectangular guide profile, and—folding the open end of the bag immediately followed by the sealing of the bag. By processing the box in the vacuum chamber before a plastic bag is put around the box, it is better to create underpressure in the box and flush it with nitrogen because the box has not yet been shut off on three sides by the plastic bag in a gas-tight manner. As a result, a better atmosphere can be created in the box or the optimal atmosphere in the box can be created in a faster manner.

A bag supply apparatus supplies a bag to a packaging machine for performing a packaging process to a bag containing a content. The bag supply apparatus includes a transfer apparatus, a detection apparatus, a takeout apparatus, and a delivery apparatus. The transfer apparatus transfers a bag containing the content, with its bag mouth being not yet sealed, in substantially a horizontal posture and along substantially a width direction of the bag, to a takeout area. The detection apparatus detects a bag on the transfer apparatus upstream of the takeout area. The takeout apparatus takes out a bag from the takeout area, with sandwiching both side edges of the bag positioned in the takeout area by a pair of sandwiching members. The delivery apparatus delivers a bag to the packaging machine. The takeout apparatus holds a bag based on a predicted position and an inclination of the bag, the predicted position being calculated from a transfer speed of the transfer apparatus and a difference between a current time and a time at which the bag was detected by the detection apparatus, and the inclination of the bag being calculated from a detection result of the detection apparatus.

A vacuum sealing machine capable of locking a cover automatically having an upper cover limiting mechanism, comprising: an upper cover (10), a lower base (20), and vacuumizing grooves. The upper cover (10) is hinged to the lower base (20), and the vacuumizing grooves are located at the front portion of the vacuum sealing machine. The vacuum sealing machine comprises a cover locking mechanism and an upper cover limiting mechanism. The cover locking mechanism is mounted on the upper cover (10) or the lower base (20); the cover locking mechanism is connected to the upper cover limiting mechanism; the upper cover limiting mechanism comprises a limiting lock plate (40) and a limiting portion (36); the limiting lock plate (40) movably mounted on the upper cover (10) is snap-fitted with the limiting portion (36) provided on the lower base (20), or the limiting lock plate (40) movably mounted on the lower base (20) is snap-fitted with the limiting portion (36) provided on the upper cover (10); and the limiting lock plate (40) and the limiting portion part (36) are snap-fitted to form a bag-entry gap having a set height between the limiting lock plate (40) and the limiting portion (36). The present vacuum sealing machine can automatically lock and open the cover, so that the entire vacuum sealing work can be automatically completed only by fixing a vacuum packaging bag with both hands and pressing a start button of the vacuum sealing machine. The use of the machine is simple and convenient.

The invention relates to an automatic pressing power device of a vacuum packaging machine, wherein the automatic pressing power device comprises main body, power plate and power airbag, wherein the power plate is connected with the main body through the power airbag and forms a telescopic closed cavity; the bottom of the main body is provided with an air nozzle communicated with the closed cavity. The automatic pressing power device provided by the invention does not need to tighten the upper cover artificially, and has the characteristics of simple structure, low cost, high structural stability, long service life and the like.

--Provided is a coffee storage bag and method capable of discharging carbon dioxide generated inside the bag while preventing the intrusion of oxygen from the outside. The coffee storage bag 10 is designed to store 500 g or less of coffee, and comprises a strip-shaped sealed portion 12 extending approximately parallel to an edge of the bag along which two overlapped end sections of a film 1 are joined together, and having a width of 5 mm to 15 mm, wherein the strip-shaped sealed portion includes a single non-joined portion 20 in which the two overlapped end sections of the film is not joined together, wherein the non-joined portion forms a single vent passage communicating the inside and the outside of the bag. The vent passage has a length of 100 mm to 400 mm, and a width of 0.5 mm to 3 mm.—
