Embodiments relate to containers capable of holding food and/or beverages. In some embodiments, the container may have an outer body and an inner body. The outer body may define an interior space and have an opening leading from the exterior into the interior space. In some embodiments, the inner body may be configured to be provided concentrically within the interior space, and may include a cavity configured to retain food or beverage. In some embodiments, the inner body may be removably retained within the interior space of the outer body. Some embodiments may also include a cover configured to be detachably coupled to the inner body and the outer body, for example to close the opening of the container.

An oil tank cap is adapted to be removably engaged with an oil inlet of an oil tank. The oil tank cap includes a cap body that is one-piece, that is plastic, and that includes a cap portion adapted to be disposed outside the oil inlet, and a plug portion extending from the cap portion along a central axis of the cap body and adapted to extend into the oil inlet. The plug portion has a surrounding surface that surrounds the central axis of the cap body, a base surface, an accommodating slot extending through the surrounding surface, and at least one recess formed in the base surface, extending towards the cap portion, and being isolated from the accommodating slot. The oil tank cap further includes a spring strip that has a positioning portion disposed in the accommodating slot, and two abutting portions extending outwardly of the accommodating slot.

Provided is a portable insulated lunch box, including: a box body (1) and a cover body (2) adapted to the box body (1); the cover body (2) defines a mounting cavity (4) passing vertically through the cover body (2), an upper opening of the mounting cavity (4) is arranged with a pressing member (5), and multiple locking members (6), that are transversely, elastically, and movably connected, are arranged in the mounting cavity (4); an outer end of each locking member (6) passes through a cavity wall of the mounting cavity (4), and an inner end of each locking member (6) is arranged with an internal push bevel (7) matched with a lower edge of the pressing member (5); an inner side wall of the box body (1) is arranged with multiple clamping grooves (8) each matched with the outer end of a corresponding locking member (6).

The present invention relates to a novel dispenser device designed for the efficient and controlled delivery of powdered substances. It comprises an aluminium housing that is both lightweight and durable, ensuring ease of handling and robust protection for the internal components. An upper cap with an anti-leak design snugly fits onto the housing, effectively preventing substance leakage. The inhaler features a mechanically operated side dispenser knob, which activates an internal mechanism to dispense precise doses of substance. Additionally, a unique bottom cap contains a refillable compartment with silica particles, providing effective moisture control to preserve the substance's integrity.

A leakproof cap of a soft water bottle and a water bottle are disclosed. The leakproof cap includes a cap body having an installation cavity with a screw thread circumferentially arranged on a side of the installation cavity, and a sealing member annularly arranged on another side of the installation cavity that is opposite to the screw thread at a predetermined distance. The sealing member is an elastic sealing member and a side of the sealing member facing the screw thread has a plurality of sealing rings. The sealing rings are arranged concentrically and evenly, and a sealing cavity is formed between adjacent sealing rings. When the bottle opening deforms following the bottle body, the sealing member adapts to the deformation and blocks the liquid through the plurality of sealing rings.

A screw cap (14, 502) configured to be removably attachable to a bottle (12) includes a base (40) and an annular skirt (42, 508) extending downwardly therefrom. One or more threads (32) extend radially inwardly from an interior surface of the skirt (42, 508). A retention feature (509) extends radially inwardly from the interior surface of the skirt (42, 508). The retention feature (509) is configured to produce at least one of an audible response or a tactile response when the cap (14, 502) is rotated with respect to a bottle (12).

A secondary dispensing system for a rigid container of a flowable substance for improved dispensing capability is disclosed, which comprises a flanged aperture positioned along the outer perimeter of the base of the container, a surface panel configured to rest on the external surfaces of the container, a hinge that enables articulated rotational movement of the surface panel, and a headed pin affixed to the surface panel and configured to insert into and seal the flanged aperture. In the closed position of the system, the headed pin seals the flanged aperture. In its open position, the headed pin is disengaged to allow gravity-based dispensing of the totality of the residual flowable substance without requiring tapering of the container's internal surfaces. The system integrates with the container without materially modifying its design. The flowable substance may be a liquid, gel, mixture, or granular material.

An oil tank cap adapted to be removably engaged with an oil tank having an oil storing space. The oil tank cap includes a cap body, an air seal, and an air valve. The cap body includes an outer casing, and a cap base being plastic and one-piece, and defining an accommodation space with the outer casing. The cap base has an annular seat portion that has at least one exhaust hole, a tube portion, a separation portion having at least one ventilation hole. The air seal has a protrusion portion, and an annular body that encircles the ventilation holes. The air valve is inserted into the tube portion, is connected airtightly to the air seal, and is operable to open or close for balancing pressure of the oil storing space and pressure of an external environment.

Disclosed embodiments relate to containers, for example for holding food and/or beverages. In some embodiments, the container may have an outer body and an inner body. The outer body may define an interior space and have an opening leading from the exterior into the interior space. In some embodiments, the inner body may be configured to be provided concentrically within the interior space, and may include a cavity configured to retain food or beverage. In some embodiments, the inner body may be removably retained within the interior space of the outer body. Some embodiments may also include a cover configured to be detachably coupled to the inner body and the outer body, for example to close the opening of the container.
