Abstract: A tamper evident container with a dispensing closure is disclosed. The patent deals with a container having a smooth neck portion and having a removable dispenser closure mounted on the neck portion. The closure, in turn, is formed with a top, a skirt depending from the top and a dispensing lid mounted on the top. The top has a dispensing orfice in it which communicates with the interior of the container. The lid is moveable from a position closing the dispensing orifice to a position opening the dispenser orifice. A tamper evident neck wrap is mounted on the container over the skirt and the lid which prevents the dispensing lid from being moved to an open position without tearing or breaking the neck wrap to show the container has opened.

Abstract: A container comprises a first tubular body, a second tubular body disposed in the first tubular body, and a tubular cap slidably engaged with the first tubular body. The second tubular body has a chamber for containing a liquid and a neck portion protruding from the first tubular body. The neck portion has a surface at an end thereof puncturable to provide a discharge opening. The tubular cap has a first end, a second end, and a needle pin disposed inside of the tubular cap and mounted on an inner wall of the tubular cap at the first end thereof. The tubular cap is slidable on the first tubular body between a first position in which the needle pin is spaced from the surface of the neck portion of the second tubular body, and a second position in which the needle pin punctures the surface of the neck portion to provide the discharge opening. A first air-tight seal maintains the interior of the tubular cap in a hermetically sealed state when the tubular cap is in the first position.

The closure may also have a membrane and pull-ring, also integrally molded as one piece. The cap may have at least one prop for preventing interference from the cap with the pouring of the contents of the container. Additionally, the spout may have a step for assisting in the prevention of interference from the cap during pouring, and for providing a predetermined sound every time that the cap is opened. Further, the closure may have a tamper-evident member to indicate that the closure has been opened. Still further, the closure may have an orienting peg for properly orienting the closure on a container.

The cap (20) is separably connected to an extremity of the cylindrical outer tube (13) coaxially with the cylindrical outer tube (13) in a position in which the cap (20) is pushed into the cylindrical outer tube (13).

Abstract: A closure is provided for a container. The closure has a body and a lid. The closure includes a tamper-indicating member connected to the body of the closure by an anchor member received in an anchor member-receiving aperture defined in the closure body. The tamper-indicating member is also connected along a frangible junction to the lid of the closure. A plug member extends from the tamper-indicating member and is receivable in a plug member-receiving aperture defined in the body. When the tamper-indicating member is depressed to force the plug member into the plug member-receiving aperture, the frangible junction is broken, and the tamper-indicating member is retained in its depressed position. This provides an indication that the closure may have been previously opened. Also, an overhanging portion of the lid can be readily engaged by a finger to facilitate opening of the lid relative to the body of the closure.

Abstract: Tamper indicating closure device for securely sealing a container in the form of a clear cap and indicator element. The cap includes knife blades in the form of ramp shaped projections which extend from the bottom side of the cap surface. Each knife blade is radially offset from the center of the cap and extends generally parallel to the radius of the cap terminating in a generally vertical planner knife face that extends in an axial direction. A tamper indicating element including a first covering layer and a second color layer is inserted into the cap prior to securing the cap and indicating element to a container. When the cap is screwed onto the container, the ramp like shape of the knife blades cause the knife blades to pass over the indicating element without tearing or piercing.

Abstract: This relates to a color change system to be incorporated in a flexing area of an end panel of a closure. The color change system includes a dark background coating on a flexing portion of the closure end panel to which there is bonded by way of an adhesive such as a varnish, ink or coating a brittle layer which due to the flipping action of the flexing portion of the end panel will fracture. The brittle layer is preferably of a light color and is colored utilizing a fluorescent dye. The combination of the background color and the fluorescent color of the brittle layer produces a first color in the original closure and when the end panel flexes and the brittle layer fractures to not only crack but also tear apart or delaminate from itself, to reflect its own light color much more brilliantly, the color of the color change system drastically changes to indicate tampering. This color change is irreversible. The color change system may also include a message indicia.

Abstract: A safety screw cap indicates prior opening of a container to protect consumers from prior contamination. The screw cap has an annular band encircling its lower end which is separated from the screw cap by a perforated line. The band is affixed to a fixing clement and the fixing element attached to the container when the screw cap is screwed in place. An unattached leader portion of the band can be lifted easily to peel the band from the container. As the band is peeled from the container, it is simultaneously tom from the screw cap at the perforations. Once the band is removed, the screw cap can be unscrewed and the container unsealed. Before peeling the band away, the screw cap cannot be unscrewed without causing obvious damage to the screw cap or band. In addition, the torque required to shear-separate the band from the fixing element, the fixing element from the container or the screw cap from the band is greater than that which can be applied easily by a normal adult.

The sheet and membrane can be stamped from a compound sheet and be of the same size. The composite portion can extend up to a line extending across a major portion of the membrane, or in another embodiment it covers a major portion of the membrane. Alternatively, the first sheet and the membrane can have a substantially common periphery in the separated portion of the sealing member forming the tab. A further embodiment provides for a sealing member that is entirely planar.

The depression also includes a formation in each portion of the side and bottom wall which extends from a first selected area of the sidewall in a direction towards another selected area in the sidewall which is spaced from the first area. The formation is engageable with the one end of the straw and when the straw is pushed into the depression, initiates rupture in the depression adjacent the second area.

Abstract: A tamper-resistant closure for a medical injection device such as a syringe includes a cap having both a blind bore sized to receive and seat tightly against the syringe tip, to prevent material from entering or being withdrawn from the device. The cap has a threaded connection to the syringe tip, and is entirely covered by a loose-fitting shield having a one-way drive mechanism which prevents the cap from being unscrewed from the device while the shield is in place. The shield has at least one internal, frangible tang protruding obliquely into the envelope of the cap, so that the shield and cap can be easily assembled, but cannot thereafter be disassembled without breaking the tang and thus providing an indication of tampering.

Abstract: A tamper-proof cap for containers, bottles and the like comprising a first driven member and a second drive member concentrically mounted on the first member and having a window through which a visible signal may be observed by a viewer. A rupturable capsule containing signal media is supported on the first driven member and displays a signal of first characteristic through the window. Upon opening the cap by causing the drive member to engage the driven member, the capsule ruptures causing the signal media to display a signal of a second characteristic through the window indicative of the fact that an attempt had been made to open the cap. In an alternative embodiment, a lens mounted on the window portion of the drive member enables viewing of the signal characteristic when the containers bearing the caps of the invention are stored on a relatively high shelf.
