A hinge structure includes: a lower member which is to be attached to a container; an upper member which is to be attached to a lid; a rotary shaft connecting the lower member and the upper member to each other; and a link mechanism connecting the lower member and the upper member to each other at a position different from the position of the rotary shaft. The link mechanism includes a plurality of links pivotably connected to each other, and a spring mechanism of a torsion coil type configured to give spring force to the upper member in a direction in which the lid is opened.

A package for a medical device such as an intermittent catheter has a case with open and closed ends. A hinge connects a cap to the case to permit movement of the cap between open and closed positions. A seal connected to one of the cap and case is engageable with the other to maintain a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap. The case includes a pair of slots at the open end. A pair of latches is formed in the cap. The latches fit into the slots to prevent lateral forces from distorting the cap when the cap is closed. A first use indication label spans a depression in the outer contour of a closed cap and case, assuring visual confirmation of breach of the label upon first opening of the cap.

In a container having a lid member coupled to a container body by a hinge, the lid member has a top panel, and an inner ring formed on the top panel, the inner ring being fitted to an inner peripheral surface of a sidewall of the container body in a closed state to seal the container body. The inner ring has an outer peripheral surface on which an outer peripheral surface projection is formed along a circumferential direction, and the container body has an inner peripheral surface on which an inner peripheral surface projection is formed along the circumferential direction, in the vicinity of an end portion of the sidewall. When closing the lid member, the outer peripheral surface projection contacts and slides over the inner peripheral surface projection to cause the lid member to be locked to the container body, with the inner ring sealing the container body.

A containment case assembly, including a tray and closing lid, comprises an upper frame that is configured to support from one to a plurality of removable screw decks is described. The screw decks have a column of first openings into which removable silicon plugs or inserts are positioned. The removable inserts include indicia or labels that indicate to a user the size of a surgical screw that is positioned in a row of second openings that are aligned in the screw deck immediately adjacent to one of the first openings. The upper frame of the containment case also has an inlet provided with a series of adjacent indicia or labels that are spaced at regular millimeter intervals for use in verifying the length of a surgical screw. The upper frame is further provided with a series of regularly spaced openings that have progressively larger sizes. These openings enable a user to verify the diameter of a surgical screw.

A durable and waterproof spinnerbait storage container having storage bags secured to a rod extending across the length of an internal compartment of the storage container such that each storage bag may hold a spinnerbait lure separately from other spinnerbait lures.

A durable and waterproof crankbait storage container having a number of individual internal storage compartments within a main storage compartment. The walls of the individual internal storage compartments are slidably removable from the main storage compartment and each of the individual storage compartments can store a single crankbait fishing product in a vertical position.

A lure box comprising a box bottom and box top. The box bottom and box top can substantially enclose an interior space, but leave an access opening through which at least a portion of the interior space can be accessed. A lure shelf having a plurality of notches for hooking fishing lures and/or hooks can be proximate to the access opening. The lure box can also have a plurality of posts that fishing line can be wrapped around and/or between, such that a fishing lure or hook and a connected fishing line can be pulled from the lure box through the access opening when desired.

A durable and waterproof fishing product storage container having a plurality of walls that are joined to form an internal compartment. The internal compartment is separated into smaller sub-compartments by a plurality of lengthwise and widthwise dividers. Storage inserts containing foam material used to hold and store fishing products, including weights and hooks, may be inserted into the storage compartment of the container. A lid is attached to each of the storage inserts so that the items stored in the foam material may be properly secured inside the inserts.

Various embodiments provide a pack for holding and re-charging an e-cigarette. The pack includes a pack battery; a body portion including a tube for receiving an e-cigarette; a re-charging mechanism for re-charging the e-cigarette received into the tube using the pack battery, wherein the e-cigarette can be re-charged in the tube without disassembly of the e-cigarette; and a dual activation mechanism comprising two separate triggers for causing the re-charging mechanism to begin re-charging the e-cigarette received into the tube using the pack battery. The re-charging begins only in response to the direct activation by a user of both of the separate triggers.

Disclosed herein are modular container systems having child-resistant containers, tray inserts and tray frames. Also disclosed are methods using the modular container systems and methods of storing substances in containers. The containers have a container base and a container cap and provide for child-resistant containers. A user can releasably remove the container cap from container base with a squeeze and lift sequence. For example, the user squeezes opposite sides of the container base, which releases a locking mechanism and allows for removal of the cap by lifting or pulling the container cap off from the container base. The components of the modular container system are modular and stackable. The modular system allow for organized, efficient, accessible and storage of the child-resistant containers. The modular container system also allows for easy counting, sorting and processing of the containers.
