PATENTS ACT 1 990 STANARD PATENT Invention Title: SEALING MEANS The invention is described in the following statement: "Sealing Means" Field of the Invention The present invention generally relates to a sealing means. In particular the present invention relates to a sealing means for sealing a bore in a medium such as concrete.
Background Art Often bores are drilled into foundations of a house to access the area below the foundation. This is particularly necessary in pest control where it may be required to spray chemicals below the foundation so as to control, repel or eradicate pests such as termites. Once a bore has been drilled and the chemical has been injected, it is necessary to seal the bore so as to prevent leakage of the chemical and its vapour, as well as preventing the ingress of any other substance such as water.
"A number of solutions have been developed in the past. Some of these solutions 15 are prone however to removal as a result of changes in temperature or vibrations. Other types require the internal diameter of the drilled bore to have o smooth and parallel sidewalls so as to provide a surface with which the sealing means can engage and seal satisfactorily.
Other problems faced by currently available sealing means is that substantial force, such as that supplied by a hammer, is required to insert the sealing means in the bore. Also, when inserting sealing means currently available it may be inserted at an angle, causing the sealing means to become jammed without an adequate seal being provided.
Existing sealing means are typically designed for a particular bore diameter and R do not accommodate bores that are slightly bigger or smaller, which may result from an incorrect drill bit being used or the walls of the bore crumbling away as a _7 result of the insertion of a prod used to inject the particular chemical.
The preceding discussion of the background to the invention is intended only to facilitate an understanding of the present invention. It should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was part of the common general knowledge in Australia as at the priority date of the application.
It is against this background, and the problems and disadvantages associated therewith, that the present invention has been developed.
Disclosure of the Invention The present invention provides a sealing means for sealing a bore, the sealing 10 means comprising a solid core member of substantially uniform cross section, a plurality of discs mutually spaced along the core member and positioned concentrically with respect to each other, each disc being of suitable thickness such that each disc is resiliently flexible, the plurality of discs having a first g. 15 disc of larger diameter than an end disc, with the discs lying therebetween being configured to provide the sealing means with a stepped frusto-conical profile whereby the end disc is inserted into the bore and the sealing means is pushed therein until the first disc is flush with or located below the surface of the medium containing the bore.
In contrast to the prior art, the configuration and flexibility of the plurality of discs allows the sealing means to be easily positioned in a bore for sealing engagement without the need to correctly position or align the sealing means with respect to the bore. Also, the bore may be of irregular shape, have nonparallel sidewalls or even have a curved axis without diminishing the ability of the sealing means of the current invention to seal the bore. Furthermore, the sealing means can be used in bores of varying diameter, negating the need to have a different sized sealing means for each bore diameter.
The solid core member provides the sealing means with the ability of being able to be driven into the bore without collapsing. This assists in positioning the sealing means to the desired depth without the sealing means becoming concertinaed within the bore.
Preferably the plurality of discs comprises a first set of adjacent discs having the same diameter and a second set of adjacent discs having the same diameter, .o whereby the diameter of the second set is smaller than that of the first set. This 10 will assist in sealing the bore.
***The end disc may be smaller in diameter than the bore diameter.
Preferably each disc is substantially flat.
The plurality of discs may be made of resiliently flexible material.
:i Each disc may extend perpendicularly from the core member.
15 The core member may have its longitudinal axis aligned with the centre of each disc.
The core member may be resiliently flexible in a direction transverse from its axis. The core member is not compressible or flexible in the longitudinal direction.
The cross section of the core member may comprise four arms extending from a centre. Preferably each arm is perpendicular to the adjacent arm. The arms provide support to the plurality of discs.
Preferably the first disc is located at a first end of the core member. This ensures that when the sealing means is in position the top of the sealing means is flush or below the surface of the medium containing the bore.
The core member and plurality of discs may be integral.
The sealing means may be made from a suitable plastic material.
The present invention further provides a sealing means for sealing a bore in concrete, the sealing means comprising a solid core member of substantially uniform cross section, a plurality of discs mutually spaced along the core member and positioned concentrically with respect to each other, each disc being of suitable thickness such that each disc is resiliently flexible, the plurality of discs having a first disc of larger diameter than an end disc, with the discs lying therebetween being configured to provide the sealing means with a stepped frusto-conical profile, 15 whereby the end disc is inserted into the bore and the sealing means is pushed therein until the first disc is flush with or located below the surface of the concrete.
The present invention still further provides a sealing means for sealing a bore, the sealing means comprising a solid core member of substantially uniform cross section, a plurality of discs mutually spaced along the core member and positioned concentrically with respect to each other, each disc being of suitable thickness such that each disc is resiliently flexible, the plurality of discs having a first disc and an end disc, the first disc and core member co-operate to provide a face at 25 a first end of the sealing means, the face defining a planar surface, -6/1whereby the end disc is inserted into the bore and the sealing means is pushed therein until the first disc is flush with or located below the surface of the medium containing the bore.
The present invention still further provides A sealing means for sealing a bore, the sealing means comprising a solid core member of substantially uniform cross section, a plurality of ribs mutually spaced along the core member and positioned concentrically with respect to each other, each rib being of suitable thickness such that each rib is resiliently flexible, the plurality of ribs having a first rib of larger diameter than an end rib, with the ribs lying therebetween being configured to provide the sealing means with a stepped frusto-conical profile, whereby the end rib is inserted into the bore and the sealing means is pushed therein until the first rib is flush with or located below the surface of the medium containing the bore.
The sealing means of the present invention may be inserted into a bore wherein the bore may be in the form of an opening in a bottle, container or like vessel.
The present invention still further provides a sealing means for sealing a bore, the sealing means comprising a solid core member of substantially uniform cross section, 20 a plurality of discs mutually spaced along the core member and positioned concentrically with respect to each other, each disc being of suitable thickness such that each disc is resiliently flexible, the plurality of discs having a first disc of larger diameter than an end disc, with the discs lying therebetween having a diameter equal to or smaller than an adjacent disc S. 25 thereto, the adjacent disc being closer to the first disc, whereby the end disc is inserted into the bore and the sealing means is pushed :therein until the first disc is flush with or located below the surface of the medium S...containing the bore.
-6/2- Brief Description of the Drawings The invention will be better understood by reference to the following description of several specific embodiments thereof as shown in the accompanying' drawings in which: Figure 1 is a side view of the sealing means according to a first embodiment Figure 2 is a cross sectional view of figure 1 through 2-2 *go• *e *e 0 0 0000 o ox Figure 3 is a cross sectional view of the sealing means positioned in a bore; Figure 4 is a view similar to figure 3 with the bore being of smaller diameter Figure 5 is a side view of the sealing means according to a second embodiment Best Mode(s) for Carrying out the Invention Referring to figures 1 to 4, the invention according to the first embodiment is a sealing means. 11 comprising a plurality of discs 13 and a solid core member :°oeo• The plurality of discs 13 are of varying diameter and range from a first disc 17 located at a first end 21 of the core member 15 to an end disc 19, the first disc 17 having a diameter larger than the diameter of the end disc 19. The plurality of discs 13 also provide a first set of adjacent discs 23 and a second set of adjacent discs 25, as best shown in figure 1. The discs in each set have the same diameter with the diameter of the discs in the first set 23 having a greater diameter than those in the second set 25, with no disc having a diameter greater :i than that of the first disc 17.
The configuration of the discs 13 provides the sealing means with a stepped frusto-conical profile.
Each disc is of sufficient thickness to allow the disc to be resiliently flexible, with the degree of flexibility progressively increasing from adjacent the core member to a peripheral region 29 thereof.
When the sealing means 11 is not positioned in a bore, each disc is substantially flat and projects perpendicular to the core member The solid core member 15 supports the discs 13 in spaced apart relation. The cross section of the core member 15 comprises four arms 27 extending from a centre, with each arm being perpendicular to adjacent arms, as best shown in figure 2.
In use the sealing means 11 is placed in a bore 40 having a diameter smaller than that of the first disc 17. As in figure 3, the diameter of the bore 40 is smaller than the first set of adjacent discs 23, but larger than the second set of adjacent discs 25. As a result the end disc 19 and the second set of adjacent discs assist in guiding and positioning the sealing means 11 in the bore 40. Further 10 insertion of the sealing means 11 will result in. the side wall 42 of the bore engaging the peripheral regions 29 of progressive discs in the first set of discs 25, flexing the discs in an upward direction, and creating a seal.
When the sealing means 11 is in position the first disc 17 sits flush with the surface 44 of the medium containing the bore 15 The orientation of the discs, when located in the bore 40, resist any force trying to eject or withdraw the sealing means 11 therefrom.
o As the discs are capable of resiliently flexing, the bore 40 can be of irregular shape, does not need to be straight along its axis and its sidewalls 42 can be S"irregular in profile. Furthermore, owing to the ability of the discs 13 to flex, the sealing means 11 may be inserted into the bore 40 without excessive force and does not necessary need to be inserted in a direction parallel with the axis of the bore 40. The engagement of the discs 13 with the sidewalls 42 seals the bore from the exit and entry of fluids.
Figure 4 depicts the sealing means 11 positioned in a hole of smaller diameter than that in figure 3. The sealing means 11 is inserted into the hole and rather than only the first set of apertures 23 engaging the side walls 42, the second set of apertures 25 also engage the side walls 42. This characteristic reduces the number of different sized sealing means 11 the technician needs to stock as one size fits a number of different sized bores.
Figure 5 shows the invention according to a second embodiment. In this embodiment, the plurality of discs 13 each have the same diameter so as to provide a sealing means 11 of cylindrical profile. When in position, such a sealing means 11 will have all discs engaging the sidewalls 42 of the bore 40, to provide a seal.
Whilst the above discussion is directed towards bores in concrete and the like, it is obvious that such a sealing means can also be used to seal test tubes, bottles and other like containers, or bores in any other material.
The bore, whilst typically circular in cross section, may be of any shape.
10 Each disc, whilst typically circular in cross section, may be of any shape to complement the bore.
Modifications and variations such as would be apparent to the skilled addressee are considered to fall within the scope of the present invention.
Throughout the specification, unless the context requires otherwise, the word S: 15 "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
