摘要:
A closure (100) comprising a top wall portion (102), a thread support member (108) extending from said top wall portion disposed with a thread (124), and at least one discrete recess (112) provided on said thread support member. The discrete recess may extend below a surface of and through said thread support member so as to form a fenestration, wherein said fenestration is configured for passage of flowable matter. The thread support member may be provided with a subregion limited by ends of said thread wherein said at least one discrete recess is provided at least partially within said subregion. The discrete recess may be formed as a three dimensional marking.

The invention relates to a childproof safety cap having two opposite bead-like threads on its inner wall. Each thread has a widened end region, a stop surface thus being formed. The associated bottle (9) has two opposite groove-like threads (15) on a connecting piece (12) of said bottle, each of which threads has a widened region (17) in the end region, an undercut (18) thus being formed in the groove by the widened region. When the safety cap is screwed on, the stop surfaces on the two bead-like threads hook in behind the undercuts (18) on the groove-like threads (15), because the safety cap is resilient due to slight deformation of its wall in the opening region as result of the screwed-on end position of the safety cap. The stop surfaces can subsequently be released from each other only if the safety cap is pressed down toward the bottle (9) onto the connecting-piece neck (11), such that the stop surfaces are pressed below the undercuts (18) while the wall of the opening of the protective cap is slightly deformed. For this purpose, the connecting-piece neck (11) forms a slipping surface that conically expands downwards. The safety cap can then be unscrewed while simultaneously being rotated.

Screw cap, loading piston, and method for aligning the screw cap and the loading piston in relation to each other and a method for screwing a screw cap onto a threaded neck portion of a packaging container. The screw cap can include a base portion having a top and a bottom surface, an annular portion raised from the base portion, the annular portion having an inner and an outer surface, and at least one first threaded portion arranged on the inner surface of the annular portion, wherein the base portion can include engagement means, such that the screw cap can engage a tool with at least one complementary engagement means in a process of screwing the cap onto the container with the complementary threaded neck portion.

In a metal cap having an outer surface formed with a coating film composed of a coating composition containing thermally expandable hollow particles in a paint, the curing initiation temperature TA (°C) of the paint, expressed as a temperature at which an attenuation rate by a rigid pendulum viscoelasticity test of the paint reaches an inflection point, satisfies TA ‰¥ Ta + 25 where Ta is the expansion initiation temperature (°C) of the thermally expandable hollow particles, and the maximum curing temperature TB (°C) of the paint, expressed as a temperature at which the attenuation rate by the rigid pendulum viscoelasticity test of the paint reaches a peak, satisfies Tb - 10 ‰¤ TB ‰¤ Tb + 10 where Tb is the maximum expansion temperature (°C) of the thermally expandable hollow particles. Because of these features, a metal cap, which is excellent in grip and openability even when dew condensation occurs on the cap, and which is also excellent in scratch resistance, is provided with high efficiency.

A container closure assembly (10) comprises a collar (12) permanently connectable about a container filling/dispensing aperture, e.g. a neck (28, Fig. 5) of a container (14, Fig. 5). A cap (18) has a rotatably disengageable connection with the collar, e.g. a press-on, screw-off threaded connection, and the assembly includes a tear strip (64) which is removed to permit rotation of the cap relative to the collar and provide tamper indication. A pouring spout (16) is detachably connected to the cap and telescopically slidable within the collar. The tear strip may be provided on the collar, or in a skirt portion or top face of the cap. An easily grippable panel-like handle may be provided, which also comprises a ratchet detent which acts as part of an alternative tamper indicating mechanism.
摘要:
A plastic closure formed from polymeric materials in accordance with the present invention is configured for enhanced performance, including enhanced strength and impact resistance. In one aspect of the present invention, the closure includes a top wall portion, and an annular, depending skirt portion which defines a plurality of circumferentially spaced, axial columns. Notably, in accordance with the illustrated embodiment, each of these axial columns is provided by a group of gripping knurls provided on the exterior of the skirt portion, with each group of the gripping knurls having relatively shallow valleys between adjacent ones of the knurls.
