The cap is one piece and has an attachment ring of elastomeric material than can to fitted around the dispenser head to retain the cap with the dispenser and the attach bottle whether the cap is fitted over the nozzle or free from the nozzle.

Abstract: A container cover assembly that has at least two states. In the first, closed state, the removal of the contents of the container through the opening of the container is prevented. In the second, open state, the removal of the contents of the container through the opening of the container is possible. The cover assembly comprises a mechanism for preventing the transfer of the cover assembly from the first state to the second state, unless at least a predetermined number of shaking motions is applied to the container and cover assembly.

Abstract: A process for producing a container comprising an outer container, an inner bag disposed therein and a pressure equalisation opening disposed in the outer container, and a container produced according to this process, is described, wherein a pre-moulding, comprising two coaxial tubes, is first produced by co-extrusion with the help of a blow mould and with an outwardly-projecting base seam being formed. The process forms a pressure equalisation opening in the outer container without endangering the integrity of the container, wherein a lower wastage rate and higher productivity are achieved. To do this, the base seam is partially cut off and a force which acts in the direction of the seam is introduced into the pre-moulding, which has a temperature of 40 degrees C. to 70 degrees C., which force breaks open and plastically deforms the base seam so that a pressure equalisation opening is formed in the base area.

Abstract: A cap is configured to mount on a can to cover a product dispenser included in the can. The cap is formed to include a passage arranged to vent vapor extant in an interior region of the cap to the surroundings outside of the cap while the cap is mounted on the can.

Abstract: A process for the production of a container (1) comprising an outer container (2), an inner bag (3) disposed therein and a pressure equalisation opening (10) disposed in the outer container (2), and also a container (1) produced according to this process, is described, wherein firstly a pre-moulding, comprising two coaxial tubes, is first produced by co-extrusion with the help of a blow mould and with an outwardly-projecting base seam (5) being formed. The process is to form a pressure equalisation opening (10) in the outer container (2) of the container (1) without endangering the integrity of the container (1), wherein a lower wastage rate and higher productivity are to be achieved. This is attained by a process wherein the base seam (5) is partially cut off and a force which acts in the direction of the seam is introduced into the pre-moulding, which still has a temperature of 40° C. to 70° C.

Abstract: A dispense system such as an aerosol or pump system includes a container having an upper rim, a collar secured to the upper rim, and a cap removably attached to the collar. The collar may be rotatably secured to the container such that when the cap is rotated, the cap and collar rotate together about the rim of the container without detaching. The cap may enclose an actuator or pump of the container preventing inadvertent dispensing of the contents as well as rendering the container more tamper resistant. Each of the cap and collar includes various features to interlock with one another. In one variation, the cap includes at least one tooth which engages a slot or an opening in the collar to achieve locking. The cap may be rotated or snap fit into place depending on the variation. Caps that are directly mountable to a rim of a container are also disclosed.

Abstract: A one-piece aerosol can cap formed of molded plastic has a top wall with an outside edge. A skirt depends from the outside edge of the top wall to a lower perimeter edge. A plurality of arcuate segments depends from the top wall inside the skirt. Each arcuate segment has an inwardly protruding detent. Each arcuate segment has an inner wall and an outer wall coupled to each other so as to define a space between the walls. An opening is provided in the top wall leading to the space between the walls of an arcuate segment for receiving a tool capable of moving the lower end of the arcuate segment outward sufficiently to release the detent so that the cap can be removed.

Abstract: A tamper-resistant closure includes a cap provided with several cap retainers adapted to engage an annular ridge surrounding a discharge valve mounted on a can and a removable tamper band coupled to a lower edge of the cap to define an undulated frangible tear line between the cap and the tamper band. Several band retainers are provided on the tamper band and adapted to engage the annular ridge. The band retainers cooperate with the cap retainers to help retain the closure on the can while the tamper band remains coupled to the cap. Once the tamper band is removed, the cap retainers engage the annular ridge on the can and cooperate to retain the remaining cap on the can.

Abstract: The plastic cover is easily removed from a metal container to allow the plastic cover and the metal container to be separately recycled. The lip that holds the plastic cover to the metal container has two or more circumferential ends which have a lower degree of engagement than the remaining portion of the lip. A press point on the cover which transforms the circular cover into an elliptical shape is positioned on the outside of the cover opposite the circumferential ends and a shoulder is mounted inside the cover opposite the press point. The shoulder bears against the container to assist in removal of the cover. Where the cover has both an inner cylinder and an outer cylinder, a rib is employed to connect the inner cylinder of the cover to the outer cylinder of the cover and to transfer pressure from the press point to the inner cylinder.

Abstract: A cap is provided for mounting on a necked-in can. The cap includes a shell formed to include an interior region and a tool-receiving aperture opening into the interior region. A ridge is appended to the shell and positioned to lie in the interior region of the cap. The ridge includes a downwardly facing ridge edge that lies inside the interior region of the cap and adjacent to the tool-receiving aperture. The ridge edge overlies a portion of an annular lip of the necked-in can when the cap is mounted on the can so that a cap-removal tool can be inserted into the interior region of the shell through the tool-receiving aperture simultaneously to engage the annular lip of the can and the ridge edge. When the cap-removal tool is rotated manually about its longitudinal axis, the cap-removal tool acts between the ridge edge and the annular lip to demount the cap from the necked-in can.

Abstract: A two-piece safety cap for a container is disclosed. The safety cap comprises a collar and a corresponding cover arranged for movement between a locked position at which it cannot be removed from the collar and a removable position at which it may be readily removed therefrom. The cover and the collar may normally be arranged in frictional engagement so that rotation of one of the components causes rotation of the other. In order to overcome the normal frictional engagement between the collar and the cover, it is necessary to rotate one of the components while restraining movement of the other component.

The safety cap also comprises a cover adapted to be mounted between a removable position and a non-removable position on the collar. Additionally, a locking mechanism is arranged between the cover and the collar so that the cover can be selectively locked thereon.
