Abstract: A method of converting on a single line printing press, two webs of material into individual rolls of ribbons of dual-layered, peelably-bonded-together lids. One layer of each lid has dispensing holes formed therein, or otherwise is cut through to form plugs, and the other layer of each label is printed with selected indicia and/or logos. The resultant product is wound in multiple layers of ribbons, or so-called, "daisy chains" of dual-layered lids around cardboard cores ready for shipment to processors of food particles, such as salt or cheese, to be secured as individual covers on cup-like containers.

Abstract: A new method fills a dispenser with cyanoacrylate adhesive from the rear. The container is sealed by a pressed-in base section (4). The latter has a vent opening which can be sealed, preferably by a plug (68) pre-mounted on it. Preferably the contacting surfaces of the container and this base have an oval shape. In this novel method, the container is first filled, while the end is still open. The base is then pressed in, sealing it onto the container. In so doing, the air displaced, is released through the base vent. During the final phase of pressing-in, the vent is plugged, irreversibly sealing it. Also claimed is an adhesive dispenser, essentially as described, with further preferred detail of the seals, the pipette construction of the container and a slot valve in the plug unit. USE--A dispenser filling method and dispenser, especially suitable e.g. for a super glue.

The connecting element (10) is subjected to an elongation when the lid (5) passes from one to the other of its open and closed positions.

Abstract: A sealing and dispensing closure for the outlet opening of a package, such as a flexible plastic bottle containing a consumable beverage. The closure comprises a closure base which is threaded onto the outlet opening of the bottle, and a removable overcap which is pivotally connected to the closure base. The closure base includes a spout having a self-sealing dispensing valve therein which is movable from a lowered closed position to a raised open position by an increased pressure in the bottle resulting from the squeezing of the bottle. The valve is positioned at a recessed location within the spout so as to preclude access to the valve by the consumer when the valve is lifted to its raised open position, and the overcap includes a post which seats in the upper end of the spout when the overcap is mounted on the closure base, and so as to form a hermetically sealed chamber above the valve which prevents the valve from lifting to its raised position in the event the bottle is inadvertently squeezed.

Abstract: The present invention relates to a dispensing container having an inner cavity for storing content to be dispensed, such as bath and beauty products. Content is dispensed when the container is squeezed through a dispensing valve. The container is supported in an inverted position so that the dispensing valve is at a base or dispensing end of the container. Accordingly, when the dispensing container is supported in an upright position by the base, bath products stored in the inner cavity gravitate toward the dispensing valve for immediate release. A travel cap seals the dispensing valve for transport. The travel cap is selectively attached to a closed end of the container when the container is in use and the dispensing end of the container to seal the dispensing valve for transport.

Abstract: A one-piece closure for dispensing product from a container has a cap secured to the container and a lid connected to the cap by a support arm through an integrally molded hinge. The support arm is pivoted by the hinge between a pair of upstanding projections on the end wall of the cap. Ribs projecting laterally from the support arm engage the projections to maintain the lid opened when the container is inverted to dispense product. When the lid is pushed closed, the ribs deform to allow the support arm to pass between the projections. In one embodiment, side edges of the ribs engage upwardly facing cylindrical camming surfaces on the projections. In another embodiment, the outer surfaces of the ribs engage confronting flat surfaces on the two projections. In the closed position of the lid, the ribs in both embodiments are received in recesses in the projections so that they do not become permanently deformed and loose their effectiveness over time.

Abstract: The dispensing container has a bottle with at least two compartments for accommodating different fluent components.

The bottle is provided with a cap that seals off the outlets from the compartments simultaneously when fitted to the bottle. The cap can be a separate component or it can be provided as a flip-top cap. The bottle is made entirely of plastics material and directional pouring spouts can be provided to ensure that the contents of the compartments leave in well-defined streams during a dispensing operation.

Abstract: This relates to the provision of the pour spout portion of a blow molded plastic bottle with a dripless lip. In one form, the terminal end of the pour spout is internally reamed at an angle so as to terminate in an exterior sharp edge, after which the resultant tapered end portion of the pour spout is engaged by a rotating tool which frictionally heats the plastic engaged thereby and progressively turns over the sharp edge through an angle on the order of 180.degree. to provide the desired dripless lip. In another form, the pour spout portion of the container neck finish is provided with an integrally molded outwardly directed hollow rib which lies in a sloping plane. The rib extends only partially about the circumference of the pour spout. The pour spout is then trimmed at an angle to the axis of the pour spout and parallel to the plane of the rib so as to provide for a pour lip of limited circumferential extent and which pour lip, depending upon the plane of trimming may terminate in a sharp dripless lip.

Abstract: A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A first barrier layer lines the carton interior and a second lines the carton exterior surface. A dispensing opening is formed, as by die cutting, in a panel of the carton. The two barrier layers span the dispensing opening, except for a concentric dispensing hole through them, with the two barrier layers sonically sealed together along an annular zone radially intermediate the dispensing opening and the dispensing hole. The pour spout carries a flange extending from the edge of the dispensing hole to a location radially beyond the dispensing opening, the flange sonically bonded to the outer barrier layer at three radially spaced, concentric zones. The spout screw cap is of a different polymer than the spout, to prevent bonding between the cap and spout.

Abstract: A non-resealable dispenser cap construction having an elongate tapered, stepped hollow spout member with an exterior shoulder intermediate its ends, and a discharge orifice. A closure cap member having a transverse closure wall is mounted on the spout member with the transverse wall engaging and closing over the discharge orifice. With the closure cap member so mounted, the transverse closure wall is distorted and biased by its engagement with the wall of the discharge orifice. One of the members is formed with two oppositely-disposed frangible tabs which overlie and are permanently attached to the other member, and each tab has a zone of weakness which can be readily ruptured upon the application of opposing rotative forces to the members. With the cap member removed the orifice is exposed, permitting discharge of the container contents through the spout member. Re-sealing of the cap member on the spout member is prevented, due to a lack of interengageable parts on the two members.

Abstract: A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A dispensing opening is formed, as by die cutting, in a panel of the carton. A pour spout carries a flange extending from the edge of the dispensing hole to a location radically beyond the dispensing opening, the flange sonically bonded to the outer barrier layer along an annular outermost knurled zone. The knurled zone sonic horn configuration yields pour spout attachment times and spout attachment integrity superior to known prior spout attachment methods and spout constructions.
