A coating method includes a first step for spraying, onto an inner area of an opening part of a cylindrical body having a bottom and arranged horizontally, a first coating material of synthetic resin containing non-volatile components while rotating the cylindrical body around a central axis thereof. After the first step, a second step is performed for spraying, onto an inner area of a barrel part of the cylindrical body, a second coating material of synthetic resin containing a lower proportion of non-volatile components than that of the first coating material while continuing to rotate the cylindrical body. After the second step is performed and before the volatile components of the second coating material vaporizes, a third step is performed in which the rotation of the cylindrical body is stopped, the cylindrical body is placed vertically, and the volatile components of the second coating material are vaporized.

A large-caliber, hoop-free and well-sealed plastic barrel, including a barrel body with a rim portion and a cover. The rim portion is provided with a sealing ring, whose outer peripheral surface is a first sealing surface. An outer side of the barrel body is provided with an annular clamp ring, which is arranged below the sealing ring. The cover is provided with a sealing groove fitting the rim portion. An outer surface of an inner side wall of the sealing groove tightly fit an inner wall of the rim portion. An inner surface of an outer side wall of the sealing groove is provided with a second sealing surface in a seal fit with the first sealing surface. An outer peripheral surface of the cover is provided with a hook strip, whose inner side wall is provided with a flange to be clamped with the clamp ring.

A coating composition includes: (a) 60 to 90 percent by weight of an active hydrogen-containing polyester having a number average molecular weight of at least 23,000, an acid value below 5 and a hydroxyl value below 10, (b) 0.1 to 10 percent by weight of a polyanhydride, and (c) 5 to 30 percent by weight of a curing agent reactive with the active hydrogens associated with (a) and (b), the percentages being based on weight of resin solids of the coating composition, where the reaction product of the coating composition forms a single coating without including a thermoplastic polymer. The coating composition is useful in coating food and beverage containers, particularly 2-piece cans formed by drawing and redrawing (DRD).

A liquid storage and dispensing device having at least two internal reservoirs to store two discrete liquids and to dispense the two liquids through a single opening without mixing the liquids until exiting the single opening, the device including a container to store a first liquid and a first reservoir mounted under the lid of the container that stores a second liquid, and an opening mechanism on the top that creates a pour opening in the top and removes a seal from the first reservoir to enable simultaneous dispensing of the first and second liquids through the pour opening while maintaining separation of the first and second liquids until they exit the pour opening.

Multi-compartment containers in accordance with embodiments of the invention are disclosed. In one embodiment, a device for storing multiple fluids in multiple compartments comprises a first compartment for storing a first fluid, a second compartment for storing a second fluid, wherein the second compartment is within the first compartment, a lid of the first compartment comprising a first aperture and a second aperture; and a holding lattice for holding the second compartment against the lid of the first compartment, wherein the second compartment is aligned with the second aperture of the lid.

The inventive technology includes a novel container dome profile and manufacturing process for improving container and bottle deformation failure resistance and extending material displacement modes through an initial deformation panel coordinated with complimentary geometric paneling and buttressing structures configured to initiate a controlled sequential dome profile deformation mode. Dome reversal, dome growth, and dome drop resistance characteristics are improved with a shallower profile formation depth, reducing pulldown, and lowering material consumption, resulting in lower overall container/bottle weight. Novel geometric contoured shapes enhance container resistance performance, supporting use of softer alloys or lower temper and yield strength to benefit post-processing efficiency and forming processes improvements while being configured to initiate controlled sequential dome profile deformation.

The Utility Model discloses a barrel with reinforced barrel rim, comprising a barrel body, and a barrel rim upwards extending along the barrel body, wherein a clamping strip extruded from the barrel rim is set around the barrel rim on four sides, the four sides of the barrel rim above the clamping strip are inclined towards the center of the barrel rim, and when the angle between the clamping strip and the four sides of the barrel rim is defined to be A, A is greater than 90° and less than or equal to 135°. The barrel rim in this patent application is reinforced, the inclination design provides the barrel rim the guiding function that when the barrel cover is hung at the barrel rim on the production line, the barrel cover can fall towards the barrel rim along the inclination in a correct way so as to be convenient for the following press; besides, the inclination of the barrel rim can separate the stress of the barrel rim so that the barrel rim can bear more pressure and hardly be deformed when being pressed.

An animal resistant canister having a canister body with a first end and second end and an inner wall and outer wall wherein the first end is open, and the second end is enclosed. A cap removably attachable to the first end, wherein the cap has an inner cap and an outer cap, the outer cap can have one or more dog supports coupled to the outer cap and one or more dogs wherein the dogs are coupled to the dog supports to allow the dogs to pivot about an axis. The inner cap is rotatable relative to the outer cap and can have one or more ramps that when the inner cap is rotated the ramps push the dogs outward towards the inner wall of the canister body when the inner cap is rotated relative to the outer cap.
