Abstract: A closing ring for a container and lid combination for securing the lid to the container includes a ring body having first and second free ends to be drawn together in order to secure the lid to the container. A link clevis and a lever clevis are welded to the free ends. A link is pivotally connected to the link clevis. A lever is pivotally connected to the lever clevis. The link is connected to the lever at a third pivot connection that travels in a lever slot. The linkage arrangement is completed by the addition of a pair of closing links that are pivotally connected together and connected to the lever at the lever clevis location and to the lever at the third pivot connection.

Abstract: A dual syringe adapter for attachment to a pair of side-by-side syringes includes three interconnected portions. A first portion is configured so as to snap onto a plunger head portion of each syringe so as to connect the pair of syringes and maintain plunger movement in unison. A second portion of the adapter is configured so as to snap onto a syringe body of each syringe to help maintain the connection of the two syringes. The third interconnected portion is positioned between the first and second portions and when connected prevents relative movement of the plungers into the syringe bodies. Weakened sections allow the connecting portion to be severed from the first and second portions thereby allowing plunger movement into the syringe bodies. Once severed, the connecting portion is secured to syringe tips for dispensing a mixed composition.

Abstract: A dispensing container for two flowable products for separately dispensing the two flowable products includes a first container receiving a first flowable product and including a first dispensing outlet and defining a hollow interior, a second container receiving a second flowable product and including a second dispensing outlet, the second container being positioned in the hollow interior. A fitment is assembled into the first dispensing outlet and connects to the second dispensing outlet. The fitment defines an inner outlet for dispensing the second flowable product and an outer outlet for dispensing the first flowable product. An adapter sleeve is assembled to the fitment. A hollow dispensing spout is inserted into the inner container, through the inner outlet, and defines an open outlet. A threaded closing cap is connected to the adapter sleeve and includes a plug portion for closing off the open outlet of the dispensing spout.

Abstract: Certain pump dispensers, for example foam dispensers, are specially adapted for inverted use. One feature, especially useful in a foam dispenser having both an air cylinder and a liquid cylinder with respective pistons is an intake conduit arrangement to increase the clearance of liquid from the container. An intermediate shell fits over the upright liquid cylinder body and carries an inlet valve positively urged upwardly to the closed position to prevent leaking. A conduit shell fits over the intermediate shell and creates an intake conduit extending down the side of the liquid cylinder to an intake opening lower down the pump body.

Abstract: An airless dispenser pump assembly includes a pump mechanism with an inlet valve that is configured to efficiently pump viscous fluids and that is able to be pre-primed when the pump mechanism is attached to a container. In one form, the inlet valve includes a seal member that seals an inlet port of the pump and an outer support member that secures the inlet valve to the rest of the pump mechanism. Two or more legs generally extend in a circumferential direction between the support member and the seal member in order to create a large flow opening for fluid flow through the inlet valve when opened and to rapidly close the inlet valve. The pump mechanism further includes an outlet valve that is configured to draw fluid back from a nozzle of the pump after dispensing in order to minimize build up around the nozzle.

Abstract: A fluid dispensing system includes a pump body configured to couple to a container. The pump body defines fluid inlet openings and a pump cavity. A shroud cover covers the pump body to draw fluid from the container. An inlet valve allows fluid from the container to enter the pump cavity through the fluid inlet openings. A plunger is slidably received in the pump cavity, and the plunger defines a fluid passage with a dispensing opening through which the fluid is dispensed. A shipping seal seals the fluid passage during shipping to minimize leakage of the fluid during shipping. An outlet valve is disposed inside the fluid passage to minimize the height of the fluid between the outlet valve and the dispensing opening so as to minimize dripping of fluid from the dispensing opening. The pump body includes a venting structure to normalize the air pressure inside the system.

Abstract: A fluid dispenser which has a pump assembly having a reciprocable plunger received in a housing having an outlet end for delivery of fluids. A handle is pivotally connected to the housing and is mechanically connected to the plunger of the pump assembly to provide a mechanical advantage. A flexible internal tube connects the reciprocable plunger to a fixed outlet from the housing. The unit maybe field stripped without any special tools.

Abstract: A sealing mechanism for a container for sealing an interface between two or more of the structural members includes a container body and a pouring spout. The pouring spout includes a ridge for securing the spout to the container body and a retention ridge that is positioned near the rim of the container body, once assembled. An angled retention surface on the spout is used to properly position a seal between the pouring spout and the container.

Abstract: A container for storage and dispensing of paint includes a unitary, molded plastic container body defining an interior volume and including an annular container opening through which the contents are dispensed. Included as part of the paint container is a dispensing spout which is positioned within the container opening and includes a pouring lip. The dispensing spout includes a threaded portion which receives a removable closing cap. The cap is constructed and arranged to close the container opening. A transporting handle is provided and is attached directly to the container body.

Abstract: A fluid dispensing system includes a pump for pumping fluid from a container. The pump has a vent opening for venting air into the fluid in the container to normalize pressure inside the container as the fluid is pumped. An intake shroud is coupled to the pump, and the shroud includes a channel opening to draw fluid from the container into the pump in a straw-like manner. A baffle is positioned between the vent opening and the channel opening of the shroud to reduce ingestion of the air into the pump so as to reduce short or inconsistent dosing of the fluid when pumped.

Abstract: A product-dispensing apparatus for manually dispensing a quantity of product, such as a herbicide with a foam consistency, includes a gripping member in the form of a handle and a cooperating container holder that is assembled with the gripping member and is constructed and arranged to receive a product-dispensing container. The container is preferably a foamer positioned in an inverted orientation utilizing a depressing plunger to dispense a foam-consistency product. The gripping member and container holder are assembled to a dispensing tip such that there is relative movement between the container holder and the dispensing tip for activation of the container plunger. A child-resistant locking ring is received by the container holder and cooperates with the dispensing tip for alternately configuring the product-dispensing apparatus in either a locked or unlocked condition. In the locked condition, foam product is not able to be dispensed from the container.

Abstract: A sealing mechanism for a container for sealing an interface between two or more of the structural members, including a container body, a pouring spout, and a closing cap, includes an outer annular edge formed as part of a threaded neck opening for the container body, a radial lip formed as part of the pouring spout and being positioned in contact with the neck portion and the closing cap being configured so as to be attachable to the container body for closing the opening and being constructed and arranged so as to seal against the outer annular edge when attached to the container body.

Abstract: The present invention is directed to a welding tip for welding polymeric materials such as containers. The welding tip includes a cylindrical body. The cylindrical body defines a central bore and includes a perimeter around the bore. The perimeter includes one or more knurls. The knurls provide the welding tip with varying temperatures and pressure points to create a more desirable weld.
