In one example in accordance with the present disclosure, a printing fluid container for a printing system is described. The printing fluid container includes a container body for holding printing fluid, a collar connected to the container body, and a cap removably engaging the collar. The collar has a plurality of collar teeth extending peripherally around the collar. The cap has a plurality of cap teeth extending peripherally around the cap. The cap teeth are configured for interfitment with the collar teeth such that rotation of the cap about the longitudinal axis in a first rotational direction effects cam-actuated removal of the cap from the collar.

An easily openable container lid includes a shell and liner. The shell includes a flat circular top wall, a skirt wall having an arcuate part extending arcuately radially outward and downward from the peripheral edge of the top wall in a longitudinal cross sectional view and a linear part extending vertically downward following the arcuate part, and a grip piece extending from the lower end of the skirt wall. The top wall, the skirt wall and at least a base part of the grip piece are integrally formed of a metal sheet, and a pair of scores each composed of first and second portions are formed on the shell. The first portions extend on the skirt wall upward from both sides of the grip piece, and the second portions extend arcuately between the upper end part of the skirt part and the peripheral edge part of the top wall.

A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

The present utility model discloses a replaceable cosmetic bottle, comprising a bottle body and a bottle cap that covers the bottle body, wherein the bottle body comprises an outer bottle and an inner container which are detachably connected; the outer bottle comprises a first threaded connection portion and a second threaded connection portion which are vertically connected, and the second threaded connection portion is in threaded connection with the bottle cap; the inner container comprises a vertical ring boss; and the inner container is arranged in an inner cavity of the outer bottle, and the vertical ring boss is in threaded connection with the first threaded connection portion. According to the present utility model, the inner container can be conveniently replaced, thereby effectively saving costs and conforming to the idea of energy conservation and environmental protection.

In some embodiments, apparatuses and methods are provided herein useful to dispensers. In some embodiments, a dispenser comprises a main body assembly including an outer wall and an inner wall, the inner wall defining an aperture through the main body, a seal, wherein the seal is affixed to the main body and encloses a lower portion of the aperture, a button seated within the aperture and configured to be manipulable between a first position and a second position, and a container housed within the button and configured to store a material, wherein when the button is in the second position the container contacts the seal to allow the material to exit the dispenser.

Disclosed are caps for closing an opening in a lid for a container, such as a paint can or bucket, wherein the caps comprises top walls comprising on their top surfaces centrally disposed recesses configured to receive a tool to rotate the caps; and threaded cylindrical projections on their bottom surfaces.

A locking cover for a container having a neck comprising: a cage made from plastic; a body made from plastic, which is fastened around the cage, the body comprising a central orifice; a cap configured to close the central orifice, the cap comprising a flat head to cover the orifice and fastening lugs caught between the cage and the body. Each fastening lug has a breakable zone, and the cap is made from a plastic material, different from the plastic material of the cage and from the plastic material of the body, the plastic material of the cap being chosen to have a resistance to rupture reduced by a dose of gamma irradiation for sterilizing the locking cover.

Device including a cap having a skirt provided with at least one thread element and with at least one relief that is separate from the thread element. A container provided with a neck having at least one screw thread in which the thread element can engage, at least one housing, the relief on the cap being configured to snap-fit in the housing at the end of a movement for pre-positioning the cap on the neck. The preferably has at least one ramp having an opposite slope and at least one space for receiving the thread element in the pre-positioned position, situated between a passage for introducing the thread element into the screw thread and an upright at least partially delimiting said housing.

The Improved Salad Dressing Preparation and Storage Container is a food preparation device that allows for conveniently measuring, mixing, and dispensing of homemade vinaigrette salad dressing. The device uses two adjacent, adjoined compartments that are volumetrically proportioned to allow for the recommended ratio of oil and vinegar (acid) to be consistently achieved by filling them with oil and vinegar to the same apparent level. The Improved Salad Dressing Preparation and Storage Container may also be configured for commercial sale pre-filled with the oil and vinegar contents, those kept separated by sealing the adjoined compartments using an adapted seal. The pre-filled container may be designed and marketed for secondary use by consumers for use in making their own vinaigrette salad dressing recipes.

A multi-chambered shot glass for storing and transporting multiple liquids for consumption or mixing at a time after the chambers have been filled includes a first body portion comprising a first chamber and a second chamber, the first chamber and the second chamber separated by an inner partition. The first chamber has a first aperture configured to form a fixed first chamber rim and a seal covering the first aperture. The second chamber includes a second aperture configured to form a second chamber rim. A second body portion having a fixed third chamber includes a third aperture. The fixed third chamber is configured for insertion into the second chamber such that the third chamber engages the second chamber in a fluid sealed configuration.
