Abstract:
A tamper-evident closure assembly is provided for a container having a neck defining an opening. The closure assembly includes a base cap configured for securing with the neck of the container. The base cap includes an aperture for providing access to the opening of the container in the neck. The closure assembly further includes an overcap configured for securing with the base cap and configured to cover the aperture in the base cap when the overcap is secured to the base cap. First and second tamper-evidencing members are associated with the base cap and the overcap, respectively. The first tamper-evidencing member provides an indication when the base cap has been removed from the neck, and the second tamper-evidencing member provides an indication when the overcap has been removed from the base cap.
Abstract:
A bottle cap with additive supply structure, comprising a bottle cap body and a storage cap; the bottle cap body comprises a first top and a first outer skirt part; the storage cap comprises a second top and a second outer skirt part, the second top, the second external skirt and a crackable part form a sealed storage space. In the invention, the additives are placed in the storage cap, the storage cap is mounted in the mounting groove, sealing performance of the storage space is better, and the additives can be prevented from being affected by damp and going bad. The bottle cap body is provided with the crackable part, the crackable part can be opened only by knocking on the storage cap downwards during use, making the additives fall into a bottle body so as to be mixed with bottled contents.
Abstract:
A tamper-evident closure for a container comprises a shell having a break line along which it is separated during a first opening of the closure. The shell further comprises a first shell portion on one side of the break line, a second shell portion on the other side of the break line, and a distortable portion, which is distorted during the first opening of the closure. The distortable portion is spaced from and separate to the break line.
Abstract:
The present invention relates to a cap for a container. The cap comprises a main body having a top plate and a circular sidewall, wherein one periphery of the circular sidewall connects to the top plate forming a closed end, and the other periphery of the circular sidewall at the opposite side of the closed end forms an opened end; and a ring member located at the opened end of the main body, separated from the main body by a first incision line, and connected to the main body by a plurality of connecting portions, wherein a plurality of second incision lines locate on the main body or the ring member and locate at one side of the plurality of connecting portions. The cap provided by the present invention will, while in its open and/or closed state, continue to be connected to its container.
Abstract:
A fitment has an axis and a registration feature. The fitment is sealed within a bottle neck in a position in which the registration feature has a predetermined orientation to the bottle neck rotationally about the axis. Preferably, the fitment has a screw thread defining a limit of rotation for a bottle cap to be screwed onto the fitment. The registration feature has a predetermined orientation to the screw thread rotationally about the axis, whereby the limit of rotation also has a predetermined orientation to the bottle neck rotationally about the axis.
Abstract:
A tamper-evident closure for a container, the closure comprising a shell having a break line along which it is separable, in which the shell further comprises a distortable portion, which is distorted upon first opening, the distortable portion being spaced from and separate to the break line.
Abstract:
A closing cap made of plastic for closing a container, having a head part and a jacket part, the jacket is substantially shaped like a hollow cylinder and has a longitudinal axis, the jacket extends from the head along the longitudinal axis, the jacket has an end segment at the end opposite the head. The closing cap has a tamper-evident part and bridge parts, wherein the tamper-evident part is arranged at a distance from the jacket and is connected to the end segment of the jacket by bridge parts. Additionally the tamper-evident part is arranged in the direction of extension of the longitudinal axis along the end segment, such that the tamper-evident part is arranged at a distance from the jacket in a direction radial to the longitudinal axis and extends in a circumferential direction to the longitudinal axis on the outside along the jacket.

Abstract:
The present invention is to provide a polyethylene resin composition for container closures and a container closure exhibiting excellent mouldability, high flowability, excellent balance between rigidity and impact resistance, excellent stress cracking resistance, excellent sliding property, low odour level, harmlessness for food, decreased elongation at high temperatures and sterilizability by electron beam upon attachment of the closure to a container. The present invention is a polyethylene resin composition for a container closure, this composition having, relative to 100 parts by weight of a polyethylene resin, 0.01 to 0.50 parts by weight of a hindered amine compound and having the following properties (a) to (f): (a) a melt flow rate (MFR) of 0.5 to 10 g/10 min, a melt flow rate (HLMFR) of 100 to 500 g/10 min and HLMFR/MFR of 50 to 200; (b) a density of 0.956 to 0.980 g/cm3; (c) a flexural modulus of an injection moulding test specimen of 990 to 2000 MPa; (d) a constant strain ESCR of an injection moulding test specimen of 10 to 400 hours; (e) a tensile elongation at break of 190% or less; and (f) a melt viscosity of 470 Pa·s or less.
Abstract:
The present disclosure provides a container and a method of making a container. In one example, the container includes a body having an upper portion, a sidewall portion and a base portion. The upper portion includes a blown finish defining a longitudinal axis and an opening into the container. A tamper evident (TE) band is formed on the finish and defines a first diameter at an outermost surface. The TE band defines at least two disconnected radial protrusions. At least one thread is formed on the finish. The at least one thread defines a second diameter at an outermost surface. The first diameter is greater than the second diameter. The TE band defines a gap between each respective disconnected radial protrusion. Each thread defines a thread start portion and a thread run-out portion. A line parallel to the longitudinal axis extends through the thread run-out portion and the gap.
