Summary for Patent: 9,731,869
Title:Container
Abstract: A container (100), comprising a thread (120) arranged around an opening (110) for engaging a corresponding thread (120) of a closure (400), more than four retention members (140) arranged around the opening (110), each retention member (140) having an end-face for abutting a member (510) on an interior surface of the closure (400) to impede unthreading of the closure (400), the retention members (140) being arranged such that a tangent (170) to each end-face of the retention members (140) intersects a plane (160, 350) bisecting the container (100) at an obtuse angle (171), wherein the retention members (140) are arranged in first and second groups, the first group (141, 410) comprising one retention member (140) having an end-face substantially parallel to the plane bisecting the container (100), and the second group (142, 420) comprising two or more retention members (140), the first and second groups being arranged on one side of the plane (160, 350), each in a respective quadrant of the container (100), the teeth of the second group (142, 420) have a first inter-tooth spacing, and a second inter-tooth spacing is provided between an end-face of the retention member of the first group (141, 410) and a first retention member of the second group (142, 420), and the second inter-tooth spacing is larger than the first inter-tooth spacing.

Assignee: Archimedes Development Limited (Nottingham, GB)
Application Number:13/983,400
Patent Claims: 1. A container, comprising: a thread arranged around an opening of the container for engaging a corresponding thread of a closure; more than four retention members arranged around the opening, each retention member having a flat surface, wherein the flat surface abuts a member on an interior surface of the closure to impede unthreading of the closure; wherein the retention members are arranged into two first retention members and two groups of retention members, the two first retention members being arranged at opposite sides of the container and wherein the flat surface of the two first retention members are aligned to define a first plane bisecting the container and wherein a first one of the first retention members and a first one of the two groups are arranged on one side of the first plane and a second one of the first retention members and a second one of the two groups are arranged on the other side of the first plane, and wherein a second one of the two first retention members and a second one of the two groups are arranged on the other side of the first plane, wherein further each of the first retention members are in separate respective quadrants of the container from one another, wherein the quadrants are defined by the first plane bisecting the container and a second plane that is perpendicular to the first plane bisecting the container and intersects with the first plane bisecting the container and wherein the second plane is aligned to the first flat surfaces of each of the two groups of the retention members; and wherein teeth of each of the two groups have a first inter-tooth spacing of substantially one tooth-length, and wherein a second inter-tooth spacing exists between the flat surface of one of the first retention members and a retention member of one of the two groups of retention members closest to the first one of the first retention members and wherein the second inter-tooth spacing is larger than the first inter-tooth spacing.

2. The container as claimed in claim 1, wherein the teeth of each of the two groups are substantially contiguous.

3. The container of claim 1, wherein the two groups comprise between two and six teeth.

4. The container of claim 1, wherein the first retention members are arranged around the opening to have only a single plane of rotational symmetry.

5. The container of claim 1, wherein the first retention members are arranged around the opening to form two teeth-free regions around the opening of generally between 35.degree. and 800.

6. The container of claim 1, wherein the container is a bottle for storing a pharmaceutical.

7. An assembly, comprising a container according to claim 1, engaged with a closure having a plurality of members on an interior surface thereof arranged to abut the flat surfaces of at least some of the first retention members.

8. The assembly of claim 7, wherein the plurality of members are resiliently flexible.

9. The assembly of claim 7, wherein the plurality of members are fingers inwardly extending at an angle of between 10 and 80.degree. from an interior surface of the closure.

10. A method of manufacturing a container, comprising: a) forming a container a plurality of mould portions, the container having more than four retention members arranged around the opening, each retention member having a flat surface, wherein the flat surface abuts a member on an interior surface of the closure to impede unthreading of the closure, wherein the retention members are arranged into two first retention members and two groups of retention members, the two first retention members being arranged at opposite sides of the container and wherein the flat surface of the two first retention members are aligned to define a first plane bisecting the container and wherein a first one of the first retention members and a first one of the groups are arranged on one side of the first plane and a second one of the two first retention members and a second one of the two groups are arranged on the other side of the first plane, wherein further each of the first retention members and each of the one of the two groups are in separate respective quadrants of the container from one another, wherein the quadrants are defined by the first plane bisecting the container and a second plane that is perpendicular to the first plane bisecting the container and intersects with the first plane bisecting the container, and wherein teeth of each of the two groups have a first inter-tooth spacing of substantially one tooth length, and wherein a second inter-tooth spacing exists between a flat surface of one of the first one of the first retention members and a retention member of one of the two groups of retention members closest to the one of the first retention members and wherein the second inter-tooth spacing is larger than the first inter-tooth spacing; (b) injecting a fluid into the mould; and (c) moving apart the mould portions to release the container from there-between.
