In some embodiments, apparatuses and methods are provided herein useful to dispensers. In some embodiments, a dispenser comprises a main body including an outer wall and an inner wall, the inner wall defining an aperture through the main body; a first seal, wherein the first 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; 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 first seal to allow the material to exit the dispenser; and a second seal, wherein the second seal is affixed to an upper surface of the main body and encloses an upper portion of the aperture.

Apparatus and methods are disclosed for container lids, suitable for use in reliable automated handling and transport of lamella carriers used for transmission electron microscopy samples, or similar light or thin objects. A lid is for use with a container having one or more cavities that can be accessible through a top surface of a container. The lid can comprise a rigid member having a planar surface. Affixed to the rigid member are a first means for constraining motion of the planar surface to one-degree of freedom movement over the top surface, and a second means for restricting motion, within the cavity, of a lamella carrier contained within the cavity.

A package includes a container and a one-piece closure. The container has a neck portion defining an opening, an external helical thread formation and ratchet catch lugs. The closure fits to the neck portion of the container for closing the opening. The closure includes a first and a second closure portion. The closure includes a top wall portion and an annular skirt portion. The annular skirt portion includes an internal helical thread formation for mating engagement with the external helical thread formation. An interior surface of the annular skirt portion includes helical ratchet teeth threads. At least one of the ratchet catch lugs mechanically catches and locks with a respective one of the helical ratchet teeth threads so as to prevent or inhibit the closure from being removed from the container. The closure opens by flipping via a hinge.

A closure includes a body that is adapted to mate with a container, a flip-top cap coupled to the body, and a hinge interconnecting the body and the flip-top cap. The body is configured to be mounted onto container to cover a discharge outlet formed in the container. The flip-top cap is configured to protect a product-dispensing spout formed on the body and block a child, for example, from accessing the product dispensing spout and removing contents from the container.

The present disclosure provides a container sealing plug, which includes a plug body and a first flexible member connected. The plug body configured to seal a receiving opening of a container body. The first flexible member connected to the plug body and having a first sleeving opening formed thereon, the first sleeving opening being configured to connect to the container body. A user can place food, liquid or other objects into the container body through the receiving opening of the container body, and then seal the receiving opening of the container body with the plug body, whereby air or water is effectively prevented from entering or leaking out the container body through the receiving opening of the container body and thus the long-term storage and freshness preservation of the content is guaranteed.

Provided are a measuring mechanism for measuring a predetermined fixed amount or an arbitrary amount of a liquid composition and discharging it, and a quantitative dispensing container and a quantitative applicator including such a mechanism. A measuring mechanism is provided that includes a base and a head defining a measurement space between the base and itself, the base and the head configured to be capable of changing the volume of the measurement space in response to a predetermined operation of the head including a measurement operation for increasing the volume of the measurement space and a discharge operation for reducing the volume of the measurement space. The base includes a first passageway for allowing the composition to flow from the outside into the measurement space, and a first check valve located on the first passageway. The first check valve of the base increases its sealability if there is a positive pressure in the measurement space.

A liquid dispensing apparatus may include a first container containing a first liquid and a second container containing a second liquid. The first and second containers each can have an opening in an end. One of the first liquid and the second liquid can contain a tastant which is essentially absent from the other liquid or is present in a relatively differing amount. When the first and the second liquids are poured from the apparatus, the first liquid flows through the opening in the end of the first container and the second liquid flows through the opening in the end of the second container, such that the first liquid begins to exit the opening in the end of the first container before the second liquid begins to exit the opening in the end of the second container.

The invention concerns a plastic closure part (10) which can be fixed to a container or a further closure part to be fixed to the container, comprising a tubular discharge portion (3) whose cross-section is closed by a membrane (7) which has a tear line (8) extending peripherally over more than 180° along its outer edge and a corresponding method for the production of such a closure. In order to develop a closure part having the features set forth in the opening part of this specification and a method for the production thereof to the effect that the problems occurring upon injection moulding due to narrow flow passages are eliminated it is provided according to the invention that the tear line (8) is formed by a cut introduced into the material of the membrane (7) with a cutting or punching tool.

The present disclosure relates to nozzles for removing a preservative from a fluid comprising a therapeutic agent to an eye. More particularly, the nozzles disclosed herein may minimize patient exposure to preservative by rapidly and selectively removing a preservative from a solution comprising a therapeutic agent. An example nozzle may comprise a flow diverter which directs a flow path from a fluid inlet to a fluid outlet over a length longer than the distance from the inlet to the outlet. In some cases, the nozzle may comprise a preservative removing agent.

The invention relates to a self-closing fragrance cartridge (1) for a fragrancer (20), which comprises a housing (3) having at least one housing opening (2). The housing (3) at least partially delimits a housing interior (4) on the inner side. In the housing interior (4), an actuating element (8) displaceable with respect to the housing (3) between a closed position (5) and a fragrancing position (6) and having at least one element opening (7) is at least partially arranged, which actuating element partially delimits an element interior (9). Here, in the closed position (5) of the actuating element (8) the element interior (9) is closed in a fluid-tight manner by means of the housing (3) of the fragrance cartridge (1). By comparison, in the fragrancing position (6) the housing opening (2) and the element opening (7) are arranged in a fluidically communicating manner, so that by means of the housing opening (2) and the element opening (7) the element interior (9) is connected in a fluid-permeable manner with an outer space (10) adjoining the housing (3) on the outer side.
