[0008] SUMMARY OF THE PRESENT APPLICATION The present invention is directed to a closure, particularly one useful for electronic commerce, and The closure covers the container and its associated closure with the bottle or other container. The jar base may be integral to the container.

[0009] The closure includes a cap base that is releasably securable to the container, and an opening. The cap includes a cap base. The cap is movably attached to the cap base and in a closed position. suitable for preventing liquid from being expelled from the container through the cap base opening when A portion of the cap base is adapted to prevent, together with the cap, the discharge of liquid from the container. Form a barrier.

[0010] The cap has a depending plug extending therefrom which is adapted to be inserted when the cap is in the closed position. When the cap is in the cap position, the cap is received within an opening in the cap base. The opening is formed by a cylindrical opening wall. When the cap is in its open position, a depending Extending outward from the plug are one or more barb flaps. When the cap is moved to the closed position with the depending plug in the cylindrical opening wall, The barb is forced up against the wall of the plug and is received within a recess in the cylindrical opening wall. The bar flap is designed to prevent extra force being required to open the cap, for example during shipping. The recessed portion abuts against the upper wall of the recessed portion.

[0011] When a consumer wants to open the cap, they exert the extra force required to open the cap. When the cap is opened, the barb flap moves from its position against the upper access wall to its position against the It then disengages and eventually returns to its original position extending outward from the cylindrical plug.

[0012] Once the cap is closed, it is further secured by a locking flap on the cap. The cap is then snap-fit ​​received within a recess on the cap base.

[0013] The cap is preferably attached to the cap base using a living hinge. Similarly, the barb flaps are preferably attached to the plug cylinder wall using living hinges. Can be installed.

[0016] Detailed Description of the Invention The closure 10 includes a cap base 12 and a cap 16. The cap base 12 is , an upper surface 14 and a cylindrical skirt 13 depending from the upper surface. As will be described, the cap includes a semicircular recess 40 shaped to receive a locking flange. Below the recess 40 is a finger access recess 42, which allows the consumer to insert the cap 16 can be easily unlocked.

[0017] The cap 16 is movable and pivotable to the cap base 12 by a living hinge 18. When the cap 16 is placed in the open position, the upper wall of the cap base 12 The opening 24 appears at 60. The top wall 60 is removed from the package to which the closure 12 is secured. It will be apparent that the cap 16 provides a barrier to the escape of liquid from the platform. The platform 22 includes a depending cylindrical plug 26. A top cylindrical sidewall 28 depends from platform 22 .

[0018] Plug 26 includes a cylindrical wall 80 depending from the underside of lid 16. At the end of wall 80 On the end opposite the end attached to the cap 16, there are two barbed flaps 82. Although the invention is exemplified herein as having two barbed flaps, Those skilled in the art will recognize that other numbers, e.g., 1, 3, 4, etc., may be preferred for a particular application. It can be easily determined whether the barb flap 82 is in contact with the cylindrical wall 80. The housing is connected to the cylindrical wall 80 by a thin plastic hinge 84 that allows it to move relative to the cylindrical wall 80. Preferably, in the cap open position, the barb flap 82 is in contact with the cylindrical wall. For example, the angle of about 45° to the longitudinal axis of the plug for the right-hand flap shown in FIG. Placed at an angle of ~90 degrees, especially 65-80 degrees.

[0022] The cap is seen, for example, in an open position in FIG. In the open configuration, the consumer closes the package as shown in FIG. If a chain is desired, the consumer closes and rotates the cap on the hinge 18. Cylindrical wall 80 As the nozzle approaches opening 24, barb flap 82 contacts cylindrical wall 88 and moves toward wall 80. When cap 16 is fully closed, barb flap 82 is bent as seen in FIG. The plate is housed in the recess 90 at an angle of preferably 100 to 180 degrees so that the plate is The device is re-housed at an angle of 110 to 175 degrees, most preferably 120 to 170 degrees, relative to the longitudinal axis of the device. .

[0023] During shipment of the package or when it is transported by the consumer, e.g. during travel, The presence of the flap 82 within the recess 90 and abutting the upper wall 94 of the recess 90 prevents the cap 16 from being opened. Increases the amount of force required to close the lock, thereby minimizing the chance of inadvertent opening. Keep it to a limit.

[0024] The consumer will receive a package 11 containing the closure 10 and the bottle 74. To open the package, the consumer inserts his or her finger into recess 42 and lifts upward. The consumer then lifts the flange 38 out of the recess 40 to open the lid 16. 8. Apply the extra force necessary to overcome the resistance caused by the abutment of the flap 82 against the This allows the flap 82 to rotate downward from the cap platform 22, When the cap 16 is open, the cylindrical wall 80 is allowed to move upward through the opening 24. When the top 16 is opened and the plug 26 is removed from the opening 24, the flap 82 is The resilience of the gyroscope 84 causes it to return to the angle shown in FIG.

[0025] Typically, as seen in FIG. 1, the closure 10 of the present invention is attached to a bottle 74 or Fasteners (not shown) are typically located on the underside of the closure to secure it to another container. Such features include threads or snap-fit ​​features, such as debossments, embossments, etc. The bottleneck may have a screw or other fixation structure. It's possible.

[0026] The cap 16 and locking flange 38 secure the bottle in place, as seen in FIG. During shipping, the device is in a closed, locked position. Thus, the locking flange 38 is received within the recess 40 and the cylindrical plug 26 fits into the opening 2. 4. The diameter of the plug 26 is such that it forms a snap fit. The diameter of the capping group may be slightly larger than the diameter of the opening 24 to provide a Plug 26 together with portion 12 prevents liquid from being expelled from bottle 74 or other container. .

[0027] E-commerce shipments often require the shipping of products in individual packages. This is cheaper than product pallets that manufacturers often use to ship large numbers of products. The closure of the present invention is designed to reduce the damage that packaging may endure during e-commerce shipping. Provides an extra measure of protection against inadvertent cap opening in response to additional stresses. do.
