A universal handle attachment tool comprises a body having a plurality of tool sides each having a container interface surface operable to engage a face of a particular container, and having a container handle interface slot operable to receive a handle of the container. The slot can comprise a keyed profile operable to interface and lock the handle attachment tool to the container. The container interface surface extends in opposing directions beyond the slot to facilitate distribution of one or more loads acting between the face of the container and the handle attachment tool to facilitate manipulation of the container. A container for storage of at least one object comprises a container body defined by a plurality of sidewalls, and a recessed portion formed a sidewall defining a recessed cavity. The container has a handle spanning the recessed cavity, whereby the recessed cavity facilitates clearance of at least one finger of a user upon grasping the handle.

Improvements in a carrying handle cushion for a wire to provide a handle or grip for a wire handle of a bucket to increase the tactile surface area. The grip uses two gates on opposite sides of the handle where the wire handle (from the bucket) passes through the grip. The wire passes through a one-way lock that retains the handle to prevent the grip from being accidentally dislodged from the bucket wire. Lifting the handle on the wire will engage the handle using only the weight of a filled bucket. While a low amount of force can be applied to engage the grip onto the wire, the handle is not removed with an inverse force. Upon engagement of the grip there is an audible and tactile indication that the grip has been completely engaged on to the bucket wire.

A rotatable connector formed from two parts, each comprising a body extending from a connecting head having a first face and an opposed second face, the second face having an arcuate tail section on an outer perimeter edge and shaped to be received by a tail socket defined between the first face and a pin extending from a proximal end of the body. When the two parts are engaged, the connecting heads are coaxial to define an axis of rotation. When the parts are rotated on the axis relative to one another, the tail section of the first part travels through the tail socket of the second part and the tail section of the second part travels through the tail socket of the first part, thereby connecting the two parts together. When the parts are rotated in the opposite direction, the parts are disconnected from each other.

A simple, portable carrier for a non-rigid container such as a plastic bag or sack that permits container to remain open for filling with articles or materials while serving as a carrying handle, especially suitable for highway crew members cleaning debris over long stretches of roadway. Device is comprised of a rigid member such as a hollow rod (tube), snug-fitting end caps, and end cap retaining bands. A segment of the open end of container is entrapped at each end of rigid member and held in place by friction between end caps and each end of rigid member. The device is reusable and is small enough to be carried in a pocket or on a belt loop.

The invention provides a bioreactor and methods for tissue cultivation. A bioreactor module comprises a container, a holder adapted to hold a scaffold containing an inherent vascular network, an inlet connectable to a vessel of the inherent vascular network, an inflatable device disposed within the container, and a pair of electrodes attached to opposing walls of the container, wherein the holder is removably receivable in the container and the inflatable device has a conduit extending through a wall of the container. An alternative embodiment provides an in-vitro method for tissue cultivation, comprising seeding an interior and an exterior of a vessel of an inherent vascular network of a scaffold with a first and a second cell type, respectively, and perfusing through the inherent vascular network with culture medium to facilitate compartmentalized co-cultivation of the first and the second cell type in different niches of the tissue. A further embodiment provides an in-vitro method for tissue cultivation, comprising seeding a surface of a scaffold with a predetermined cell type, and perfusing the scaffold with culture medium from an opposite surface of the scaffold through the scaffold and towards the seeded surface to create a nutrient/oxygen gradient and cause migratory diffusion induced penetration of cells towards the opposite surface.

The present invention is a portable device accessory that includes a cover, a plurality of hooks, a connector, a first adhesive pad, and a second adhesive pad. The first adhesive pad is attached to one side of the connector. The other side of the connector is attached to a portable device, such as mobile phone, by the second adhesive pad. The user may remove the cover to reveal the first adhesive pad, then temporary attaches the first adhesive pad to a mounting surface so the user may take a selfie with the portable device. After the portable device accessory is detached from the mounting surface, the user may place the cover over the first adhesive pad and pressed the cover and the connector towards each other thus enabling the plurality of attachments to be frictionally attach around a lateral wall of the connector.

A bottle handle assembly includes a neck engagement portion including a neck ring defining a central aperture, a handle portion coupled to the neck engagement portion, and a plurality of tabs extending radially inward from the neck ring. The plurality of tabs includes a first grouping of tabs separated from a second grouping of tabs, each tab of the plurality of tabs having a width that is approximately five millimeters to approximately six millimeters.

This present invention relates to a case or package carrier for holding consumer goods, such as bottles of water, juice, or other beverages or drinks, and enables a user to easily carry and lift the case carrier. The case or package carrier comes with either an integrated handle or a standalone handle, which may be applied by the user to the carrier. Additionally, the handle of the case carrier is made of a durable collapsible plastic which allows the user to save space while storing the cases, as the user can easily stack the cases one on top of the other. The case carrier helps to reduce the strain on the user's back and body due to lifting of the cases.

The invention discloses a handle sliding structure and a selfie stick using the same, and belongs to the field of selfie sticks. The handle sliding structure comprises a long rod and a handle, wherein the handle is a cavity structure and is slidably arranged on the long rod, and the long rod can slide along the handle to retreat into or stretch out a cavity. When the selfie stick is used, the long rod can stretch out of the handle, and only the tail end of the long rod is connected to the handle, so that the length of the long rod is fully used; and when the selfie rod is not used, the long rod can partially retreat into the handle in the length direction, so that the portability is good.
