Abstract: A device and method for removing closures from laboratory sample containers is the subject of the present invention. The device consists of a tubular member which is large enough to contain a laboratory sample container or vial. Integral with one end of the tubular member is a housing member which is large enough to contain the stopper or closure for the laboratory vial and is thus of a diameter larger than the tubular member. The end of the housing opposite the tubular member is closable with an irreversibly locking cap. A vial with a stopper to be removed is placed into the cap end of the housing member and is received by the tubular member unitl the stopper rests on the bottom surface of the housing member. The cap on the housing member is closed and a force is exerted on the vial to dislodge the stopper from it. The vial is pulled through the tubular member, leaving the stopper in the housing member.

Abstract: A product preserving stopper (2) is used to seal the opening (62) in a container (28) and remove oxygen within the container. This accomplished by incorporating a metal-air primary cell (32) into the construction of the stopper. The cathode of the cell is open to the interior (26) of the container so that by electrically connecting the anode and cathode, typically by shorting out the anode can (36) to the cathode can (34) using a resilient contact (40), any oxygen in the container is removed through the action of the metal-air primary cell. Electrical connection between the contact and cell is initially prevented by placement of a removable separator tab (48) between the contact and the anode can. The stopper becomes actuated only after removal of the separator tab by the user to lengthen the shelf life of the cell. Preferably the stopper is packaged within an oxygen impermeable package (70) to further increase the shelf life.

The container can absorb the variations in pressure that the fizzy drink generates in various environmental conditions, and simultaneously, can compensate for the osmotic losses of gas. The container is furthermore provided with a shape (11, 12) of the cover and a shape (4, 5) of the base which allows side-by-side storage of the containers and stacking one above the other in a warehouse, and also the insertion into the cover of an opening device (15, 25) for pull-off or push-down opening.

Abstract: A container for holding articles includes a tamper detectable lid which is integrally attached to the container to overlay a capped opening to the container. Removal of the lid from the container provides evidence of tampering and must, in any event, be accomplished to operably expose the capped opening to the container.

Abstract: This invention relates to an endwall for a container having a panel portion surrounded by a substantially vertical wall portion which terminates into a narrow rim. The rim is connected to a sidwall of the container. The wall portion extends outward from the container and is adapted to be reformed inwardly into the container in a controlled manner by an external mechanism to reduce the volume thereof after the container has been filled and sealed. The invention also relates to a method of packaging a product in a container having a body opened at one end and closed at an opposite end by an endwall as described above. The method includes the steps of filling the container with a product and sealing the open end, thermally treating the filled and sealed container, and reforming the endwall inwardly into the container. The sequence of steps can be rearranged.

Abstract: The neck of a plastic container for motor oil or similar thin fluids is formed wiht plural, discrete, smooth external conical surfaces and further formed with shoulders below each such surface. The cap for such neck has an interior generally complementary to the exterior of the neck. Internal cap beads engage under the shoulders of the neck. At least the lowermost cap shoulder is preferably interrupted. Above each bead is an internal circumferential rib which seals against the corresponding smooth conical surface of the neck. The lower portion of the cap including the lowermost bead may be torn away, permitting the upper part of the cap, which functions as a reclosure cap, to be pried off the neck. For such purpose, the cap wall is made thin below the second locking bead and a downward-slanted scoreline extends from the thin area to the bottom edge of the cap. A tear tab extends below the bottom edge of the cap adjacent the terminals of the score line.
