Abstract:
The present invention provides a disposable bioprocess bag, a manufacturing method therefor and a hot-melt annular welding machine, relating to the technical field of biopharmaceutics. The manufacturing method comprises: preparing a first cropping template to a fourth cropping template according to a top, an upper portion, a lower portion and a bottom of a bioreactor; cropping a raw material film according to the first cropping template to the fourth cropping template to obtain a first membrane material to a fourth membrane material, wherein the fourth membrane material directly serves as a rounded bottom; welding at least two pockets on the first membrane material to obtain a rounded top; welding the second membrane material to obtain a cylindrical upper portion; welding the third membrane material to obtain a lower portion in the shape of an inverted rounded truncated cone; and welding, using a hot-melt annular welding machine, the rounded top, the cylindrical upper part, the lower portion in the shape of an inverted rounded truncated cone and the rounded bottom, to obtain a disposable bioprocess bag. According to the present invention, the physical properties of the welded edge of the disposable bioprocess bag are improved, and the fit of the disposable bioprocess bag to the bioreactor are also enhanced.
Abstract:
The present disclosure providing a cushion pad includes at least one cushion unit including at least one die-cutting region, a length of the die-cutting region increased when the die-cutting region is unfolded; the die-cutting region is unfolded to form a buffer layer that causes the second surface to expand in a thickness direction of the second surface to play a buffering and protective role thereof; the die-cutting region is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag with the cushion unit is of a plane structure after production; when the packaging bag is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion unit is expanded to form the buffer layer, to protect the object inside the packaging bag.
Abstract:
A file folder with multiple pockets and a method of making is disclosed. Cover panels (16,18) are joined along a central axis (11), at least one primary pocket is formed with a pocket panel (18a), a second pocket panel (40) is located in a primary pocket space (24) thereby subdividing the pocket space into a first pocket space between the first pocket panel and the second pocket panel and a second pocket space between the second pocket panel and one of the cover panels, the second pocket panel (40) includes an extension (50) which is folded over and affixed to the first pocket panel thereby forming a closed inner edge on the front pocket.
Abstract:
This invention relates to a heat sealing element for use in a heat sealing jaw in cooperation with an opposing backing jaw for sealing layers of film together to form a sealed portion and a notch within the sealed portion, the heat sealing element comprising: a sealing face for pressing the layers of film together against the opposing backing jaw and forming the sealed portion, the sealing face having a protrusion for forming the notch within the sealed portion; and a clamping portion adjacent to the sealing face, the clamping portion being disposed at an orientation diverging from a plane along which the layers of film are sealed together.
Abstract:
A reclosable, tamper-proof, fillable package includes a first side panel and a second side panel joined to each other along a pair of spaced side seals. A bottom wall extends between the first and second side panels with the bottom wall and the first and second side panels defining a package interior. A tamper-evident structure having opposite sides connected to each other extends above a combined zipper closure and slider device, and is connected to the zipper closure. Only one side of the tamper-evident structure is initially connected to one of the first and second side panels so that a fill opening adapted to receive a product is created between the other side of the tamper-evident structure and the other of the first and second side panels.

Abstract:
A rotary cutting assembly is provided for cutting a panel from an envelope blank or the like. The die holder has an outer surface and a plurality of surface orifices radially communicating with corresponding feed tubes for supplying vacuum or air to the surface and into the vicinity of the envelope blank. A novel air delivery assembly is provided for delivering vacuum and/or air to the die holder comprising a stationary plate disposed at least at one end of the die holder and defining a groove member for selectively supplying vacuum and/or air so that when rotation of die holder aligns the longitudinal feed tubes with the groove member a supply of vacuum or air is selectively supplied at the surface orifices of the die holder. Another embodiment of the die holder may have an outer surface having a extending along the longitudinal axis for detachably receiving the leading end of the cutting die and a plurality of magnetic members disposed in the die holder surface for attracting the cutting die. In order to maximize the number of orifices while minimizing the number of magnetic members, it is preferred that the magnetic members be disposed in a plurality of rows wherein each row contains alternating magnets and orifices and a row of orifices are disposed between each adjacent row of magnets. A novel valve assembly is provided for controlling the flow of air to the surface orifices.
Abstract:
A container (100) is formed by being folded and sealed on one of a multiplicity of male dies (12) of an apparatus (10). The male die (12) with the container (100) placed thereon is inserted into a female die (120). The female die (120) retains the container (100) while the male die (12) is removed therefrom. Lips (110-112) of the container (100) are sandwiched against the female die (120) while product is pushed thereon to prevent collapse of the container (100). The multiplicity of male dies (12) are relatively moveable by rotating about an axis (20) relative to the female die (120).
Abstract:
A bag making apparatus includes an intermittent feed device for feeding sheet panels, an adjustment device for detecting upper and lower thresholds for a length of the sheet panels included in a section from a first drive roller pair to a second drive roller pair, a movement device for moving a processing device and a sensor together as a movable group in the longitudinal direction of the sheet panels. The movement device moves the movable group upstream in response to the adjustment device detecting the upper threshold and moves the movable group downstream in response to the adjustment device detecting the lower threshold. If the movable group is moved, the intermittent feed device determines an intermittent feed distance based on a moving distance of the movable group in addition to output from the sensor and feeds the sheet panels by the determined distance using the first drive roller pair.
