Abstract
Abstract A fluid sampling apparatus for taking samples of fluid from predetermined depths in a body of water comprises a receptacle for releasably holding therein a sample collection bottle. A single suspension means such as a rope is provided, by means of which the assembly can be raised and lowered. Attached to the bottom of the suspension means is an interference fit stopper such as a cork and a resilient engaging means, for releasably engaging ribs on the neck of a bottle disposed within the receptacle. As the assembly is lowered by means of the suspension means, it is suspended by means of the resilient releasable means engaging against ribs on the bottle neck. When it has been lowered to the required depth, the suspension means is jerked suddenly upwardly, causing the resilient releasable means to release the bottle, with consequent removal of the stopper to permit filling of the bottle. After freeing from the bottle, the resilient engaging means abuts against the top wall of the container, allowing the assembly to be withdrawn upwardly by means of the suspension means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
206 words
A receptacle for releasable reception therein of an interference fit stoppered type container, said receptacle comprising: a weighted base and side wall extending upwardly therefrom to define a container-receiving space, said side wall having a front opening therein and closure means, permitting withdrawal of a container from the container-receiving space forwardly through said front opening upon opening of said closure means, and the container being checked against such withdrawal when the closure means is closed; restraining means on said receptacle adapted to engage the container and restrict movement of the container away from said weighted base when within the container-receiving space; suspension means extending upwardly from the receptacle; an interference fit stopper for said container and resilient engagement means associated with the stopper, secured to a lower end of said suspension means, for resiliently releasably engaging the container when the stopper is fitted to the container and preventing removal of the stopper therefrom; the resilient engagement means being releasable from engagement with the container, and the stopper consequently being removed from the container, upon upward jerking force applied to the suspension means; the receptacle being suspendable by said suspension means whether or not the resilient engagement means and the stopper are in engagement with the container.
Claim 2
Dependent Claim
206 words
A receptacle for releasable reception therein of an interference fit stoppered type container, said receptacle comprising: a weighted base and side wall extending upwardly therefrom to define a container-receiving space, said side wall having a front opening therein and closure means, permitting withdrawal of a container from the container-receiving space forwardly through said front opening upon opening of said closure means, and the container being checked against such withdrawal when the closure means is closed; restraining means on said receptacle adapted to engage the container and restrict movement of the container away from said weighted base when within the container-receiving space; suspension means extending upwardly from the receptacle; an interference fit stopper for said container and resilient engagement means associated with the stopper, secured to a lower end of said suspension means, for resiliently releasably engaging the container when the stopper is fitted to the container and preventing removal of the stopper therefrom; the resilient engagement means being releasable from engagement with the container, and the stopper consequently being removed from the container, upon upward jerking force applied to the suspension means; the receptacle being suspendable by said suspension means whether or not the resilient engagement means and the stopper are in engagement with the container.
Claim 3
Dependent Claim
41 words
The receptacle according to claim 1 including a top wall disposed above the side wall, the suspension means passing downwardly through an aperture in the top wall, the engagement means and stopper being too large to pass upwardly through said aperture.
Claim 4
Dependent Claim
43 words
The receptacle according to claim 2 wherein said weighted base is generally circular and said side wall is generally cylindrical, the said restraining means comprising protrusions extending generally radially inwardly from the upper part of the side wall to engage the container shoulder.
Claim 5
Dependent Claim
57 words
The receptacle of claim 3 wherein the side wall is split axially from the top of the front opening to the upper edge thereof, the side wall thus being circumferentially expandable and contractable between a container withdrawal position and a container restraining position, said closure means holding the side wall in a circumferentially contracted position when closed.
Claim 6
Dependent Claim
51 words
The receptacle of claim 4 wherein some of said inwardly extending protrusions comprise integral formations of the side wall on opposed sides of said axial split, and the closure means comprises a clasp extending from one to the other of said protrusions across the split, when the closure means is closed.
Claim 7
Dependent Claim
14 words
The receptacle of claim 5 wherein the weighted base includes a drainage hole therethrough.
Claim 8
Dependent Claim
50 words
The receptacle of claim 6 wherein the engagement means comprises a generally inverted U-shaped formation, the downward extremities of the arms thereof having inwardly projecting portions to releasably engage a container formation therebetween, and the stopper being disposed between said arms and extending from the base of the U-shaped formation.
Claim 9
Dependent Claim
32 words
The receptacle of claim 6 wherein the axial extent of the container receiving space, defined between the weighted base and the inwardly extending protrusions, permits limited axial movement of the container therein.
Claim 10
Dependent Claim
29 words
The receptacle of claim 4 wherein the top wall is arcuately curved upwardly across the top thereof, and disposed within the cylindrical axial projection of the side wall thereof.
Claim 11
Dependent Claim
118 words
In combination, a receptacle as claimed in claim 4 and a container in the form of a bottle having a narrow upper neck, cork-receiving aperture at the top of said neck and shoulders below the neck thereof, said shoulders being engageable against the inwardly extending protrusions at the upper part of said side wall to prevent axial withdrawal of the bottle from the container, and the resilient engagement means engaging outwardly extending ribs on the neck of the bottle, the axial distance between the weighted base and the inwardly extending protrusions of the container being greater than the axial length of the bottle from base to shoulder, to permit limited axial movement of the bottle within the receptacle.
