A pyramidal receptacle includes a planar base. A body portion includes separated angled members connected to each other at lateral edges defining a truncated pyramid having a hollow interior. The separated angled members extend from a top edge to a bottom edge. The body portion is coupled to the planar base at the bottom edge. A cap portion includes separated angled walls connected to each other at lateral edges and extends to an apex defining a pyramid having a hollow interior. The separated angled walls extend from the apex to a lower edge. The lower edge includes slide rails formed thereon. The top edge of at least two opposing separated angled walls includes guide channels formed thereon. The slide rails extend from proximal to distal ends and the proximal end of the slide rail including a guide block formed thereon which is received in the guide channels and is moveable laterally between locked and unlocked positions.

A bottle assembly is provided. The bottle assembly comprises a bottle having an end portion including a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided. The valve assembly comprises a base member and a sealing member. The sealing member is moveable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and extend to a periphery of the sealing member. The one or more channels are arranged to allow air to enter the drinking vessel from the periphery of the sealing member when the sealing member is in the unsealed position.

The disclosed principles provide for a welding technique welding the flanges of a rigid lid sealed onto a rigid tray, such that the two may be easily separated but still repeatedly reclosable such that the rigid package may be reused. For this unique and advantageous ultrasonic welding technique, the disclosed principles provide for the inclusion of a unique delamination layer between the similar rigid materials used for forming the flanges of both the lid and the tray. The disclosed principles provide for the delamination layer to be provide on one or both of the two rigid materials, but behind the seal interphase area so that the hermitic seal may still be created. This delamination layer operates such that it peels apart (i.e., delaminates) as the ultrasonically sealed rigid material of the lid flange and rigid material of the tray flange are pulled apart while opening the package initially.

The present disclosure provides a paperboard packaging container comprising a tubular paperboard container body, a container bottom and a container lid. The container body comprises a container body abutment edge at the container opening. The container body has an inner surface facing towards an inner compartment in the packaging container and an outer surface facing away from the inner compartment. The container lid comprises a lid collar having an abutment edge adapted for abutting against the container body abutment edge, and a lid plug-in portion. The plug-in portion has a side surface extending in the longitudinal direction and faces the inner surface of the container body, when the container lid is in a closed position. The lid collar is made of the same material as the container body and the lid collar is delimited from the container body by a slit or by weakening means.

Apparatus and installation methods for sampling ports are disclosed. Sampling ports include a port housing and a lid assembly. The lid assembly is configured to sealably close against the port housing. Additionally, the lid assembly can be secured, such as with a lock, to the port housing. In one aspect, the port housing includes a sample mount arrangement configured to receive a sampling assembly. The sample mount arrangement defines a sampling channel and the port housing defines a sampling opening and a first securing mount. The lid assembly includes a latch arrangement and defines a second securing mount.

A sealable container system contains a body and a lid assembly. The body includes an internal volume defined by a bottom and side wall(s) and divot(s) with a cavity at an upper edge of and in an inside surface of the side wall. The lid assembly includes a lid with outer and inner walls at its bottom side with a channel in-between. A gasket couples to the lid with a wall portion residing within the channel and a lip outside the channel. When the lid assembly is pressed into the body, the lip of the gasket abuts the divots and forms a gap with the side wall, where air in the internal volume exits through the gap. When the lip travels past the divots, the lip fully seats against the inside surface of the side wall, and negative air pressure is imparted to the internal volume of the body.

The present invention addresses the problem of providing an article accommodation case that can be formed at low costs, is excellent in connecting workability, and secures high stability in a stacked state. In order to solve the above problem, an article accommodation case having an opening at an upper part thereof and having a substantially cubic shape or a substantially rectangular shape is provided, wherein a convex part serving as a leg part is formed on a bottom-wall lower surface thereof, the convex part being configured to fit into the upper opening of a case below the case when the cases are stacked; inwardly or outwardly protruding upper tongue pieces are formed in a vicinity of upper-end centers of mutually facing side walls thereof; and lower tongue pieces protruding in directions opposite to directions, in which the upper tongue pieces protrude, are formed on the bottom-wall lower surface, the lower tongue pieces engaging the upper tongue pieces of the lower case when the cases are stacked to connect the cases to each other.

A food package for sliced food products to be maintained with a fluffed appearance, the package including a rigid base member forming a compartment for receiving the food product and a rigid lid sealed to the compartment. Advantageously, the base member includes a bottom wall and side wall portions that are configured to engage the food product to hold the slices in a fluffed arrangement thereof. Preferably, one or more tapered side wall portions hold the food product upwardly toward the lid and inwardly toward a center of the package. In preferred embodiments, the base member and lid provide a rigid-rigid construction of the food package. In preferred embodiments, the food package is also configured to stand-up in a vertical display orientation and does not require the food product be contained within a sealed pouch within the compartment.

A safety cover box is used to prevent unauthorized access to an electrical device stored within to vulnerable users such as children or pets. The safety cover box prevents harmful accidents by restricting access to the electrical connections of the electrical device. To do so, the safety cover box may include a safety lid, a box body, and a safety lock mechanism. The box body is designed to completely enclose the electrical device so that all electrical connections are safely protected. The box body also enables the normal operation of the electrical device without obstructing the connection of external electrical devices to the electrical device stored within the box body. The safety lid is designed to seal the box body to prevent access to the electrical device stored within. The safety lock mechanism is designed so that only authorized users can remove the safety lid from the box body.

A container system includes a first container including a bottom wall, at least one sidewall, and an open top, with a plurality of indented recesses formed in the bottom wall. A first lid closes the open top of the first container. A second container includes a bottom wall, at least one sidewall, and an open top. A second lid closes the open top of the second container, with a push indicator structure formed at a center portion of the second lid, and with a plurality of registration bumps formed about the push indicator structure. The first container is stackable on the second lid such that (i) each of the registration bumps in the second lid is aligned with an adjacent one of the recesses in the bottom wall of the first container and (ii) surfaces of the registration bumps are spaced from surfaces of the adjacent recesses.
