Abstract
A solution applicator comprising a solution container having a frangible twist-off member that enables solution in the solution container to flow out of the solution container when the twist-off member is twisted. The solution applicator also comprises an applicator head having a proximal end and a distal end and a solution pathway extending from the proximal end to the distal end, the applicator head being engaged with said solution container at the proximal end, the applicator head having an aperture and applicating material at the distal end, and the applicator end having a receiving member that the twist-off member engages when the applicator is rotated relative to the solution container to thereby open the solution container at the twist-off member to enable fluid to flow from the solution container to the applicating material. The solution applicator of the present invention is novel in that it includes a twist-off member that retains solution in the solution container until the solution container and the applicator head are rotated relative to each other to thereby cause the twist-off member to be twisted to allow solution to be applied.
Description
FIELD OF THE INVENTION
The present invention generally relates to solution applicators and, more specifically, to solution applicators for applying antimicrobial solution to skin before surgery.
BACKGROUND AND SUMMARY OF THE INVENTION
Antiseptic preparation of patients for surgery typically includes applying antimicrobial solution to the patient's skin and scrubbing the affected area. There are a number of ways that these antimicrobial solutions are applied from the basic method of dipping a sponge or piece of cotton in an open dish of antimicrobial solution and applying the solution to the patient's skin to more complex, hand-held solution applicators.
There are a number of solution applicators that use spikes and other sharp members that puncture a cartridge or container that contains antimicrobial solution. In many of these types of solution applicators, the cartridge or container is moved longitudinally relative to the spike which then punctures the container to let the solution flow from the container to a sponge on the end of the applicator. These types of solution applicators can rupture during shipping, if the applicator is dropped or sufficient pressure is exerted onto one end of the applicators to thereby force the spike into the solution container, which can inadvertently or accidentally rupture the container and cause the solution to flow out of the container. Some examples of solution applicators using spikes are U.S. Pat. Nos. 4,415,288; 4,498,796; 5,120,301; and 5,769,552.
There are other solution applicators that involve the use of pressure to break or rupture an ampoule inside the applicator by squeezing the sides of the ampoule together. Other solution applicators require bending of an ampoule to break it or pushing an ampoule forward against a member which then bends the ampoule to break it, thereby releasing the solution so that it can then be applied. These types of solution applicators also have problems with breakage during shipping, when dropped, or inadvertently by a user that causes the compartment or ampoule inside of the solution applicator to rupture and thereby release the fluid solution when it is not desired. Some examples of these types of patents discussed above include U.S. Pat. Nos. 3,757,782; 5,288,159; 5,308,180; 5,435,660; 5,445,462; 5,658,084; and 5,927,884.
There is a need for a novel solution applicator that will not easily break during shipment, when dropped, or inadvertently by a user prior to desired use of the solution applicator. The present invention meets these needs. The present invention is a novel solution applicator comprising a solution container having a frangible twist-off member that enables solution in the solution container to flow out of the solution container when the twist-off member is twisted. The solution applicator also comprises an applicator head having a proximal end and a distal end and a solution pathway extending from the proximal end to the distal end, the applicator head being engaged with the solution container at the proximal end, the applicator head having an aperture and applicating material at the distal end, and the applicator end having a receiving member that the twist-off member engages when the applicator is rotated relative to the solution container to thereby open the solution container at the twist-off member to enable fluid to flow from the solution container through the solution pathway and through the aperture in the applicator head to the applicating material.
The solution applicator of the present invention is novel in that it includes a twist-off member that retains solution in the solution container until the solution container and the applicator head are rotated relative to each other to thereby cause the twist-off member to be twisted to create an opening in the solution container that allows solution to be applied. The present invention overcomes the difficulties of the prior art inventions in that it is highly unlikely that during shipment, when dropped or inadvertently by a user, the solution container would be rotated relative to the applicator head. This is a key feature of the present invention. Inadvertent openings of solution applicators usually occur if they are dropped or jammed or bent, so the twisting action required to open the solution applicator of the present invention is a very beneficial feature and superior to the prior art inventions.
Various objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the enclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as a basis for teaching one skilled in the art how to make and/or use the invention.
Referring now to the drawings, preferred embodiments of the solution applicator of the present invention are shown in
FIGS. 1-13
. The solution applicator
20
of the present invention includes a solution container
21
that contains the solution to be applied by the solution applicator
20
. The solution may be various types of liquids or gels to be applied on a surface, but the present invention is very useful for antimicrobial solutions applied to patients before surgery. The solution container
20
is self-contained in that no other implements, techniques or tools are necessary for accessing and applying the solution.
The solution container
21
may be shaped like a cylindrical bottle or shaped like other types of reservoirs or containers that hold solution. The solution container
21
includes a frangible, twist-off member
25
that enables solution in the solution container
21
to flow out of the solution container
21
when the twist-off member
25
is twisted to thereby provide an opening through which solution in the solution container
21
may flow. The twist-off member
25
may also be a type of twist-to-break member that will not actually twist off completely, but will break enough so that an opening will be created to allow the solution in the solution container
21
to flow out of the solution container
21
. This enables solution to be available for application by the solution applicator
20
.
The solution container
21
may include a cap
22
that is either integrally formed as part of the solution container
21
or the cap
22
may be designed for threaded connection to threads on the container portion
91
of the solution container
21
to thereby form a sealed solution container
21
to hold the solution. In this embodiment, the cap
22
would have the twist-off member
25
integrally formed as part of the cap
22
.
As shown in
FIGS. 1
,
2
,
2
A,
2
B,
2
C,
2
D and
3
, the solution applicator
20
includes an applicator head
26
engaged with the solution container
21
. The applicator head
26
has a proximal end
76
and a distal end
77
and a solution pathway
29
that extends from the proximal end
76
to the distal end
77
. Solution pathway
29
may be a tube, duct, channel, lumen, wick or other type of pathway through which liquids can flow. This solution pathway
29
allows solution to flow from the solution container
21
(when the twist-off member
25
is twisted to create an opening in the solution container
21
) and then to be able to flow through orifices/apertures
78
(see
FIG. 6
) to the applicating material
31
.
The applicating material
31
includes any type of material that will absorb the solution and allow the solution to be applied to a surface (e.g., a patient's skin). A suitable applicating material
31
for a solution applicator
21
is foam sponge, but many other suitable applicating materials
31
(such as cotton swabs, pads, etc.) that are porous and can retain and distribute solution may be used. It is preferable if the applicating material
31
allows the solution to flow into the applicating material
31
, but does not allow the liquid solution to drip from the porous applicating material
31
. Flat surface
30
provides a mounting surface to which the applicating material
31
is attached. The flat surface
30
has apertures
78
therethrough in order to allow the solution to get to the applicating material
31
from the solution pathway
29
.
Applicator head
26
may also have a slot
32
near the proximal end
76
that is engaged by a locating pin
23
that protrudes outwardly from the cap
22
of the solution container
21
to ensure proper orientation of the applicator head
26
as it is coupled to cap
22
of the solution container
21
. Locating pin
23
engages slot
32
to provide a means to retain the engagement of applicator head
26
onto cap
22
of the solution container
21
after assembly. Applicator head
26
has a receiving member
27
that forms an area that cooperates with twist-off member
25
such that when the applicator head
26
is rotated relative to the solution container
21
, the receiving member
27
will tear or break the twist-off member
25
, which opens the solution container
21
and enables solution to flow from the solution container
21
. The receiving member
27
can be formed in many suitable ways (including a tongue-and-groove arrangement), as long as it will engage and tear the twist-off member
25
when the applicator head
26
is rotated relative to the solution container
21
.
A preferred embodiment of the receiving member
27
is shown in
FIG. 3
, in which the receiving member
27
includes two parallel members
80
attached to a cross member
28
that extends across the solution pathway
29
of the applicator head
26
. As shown in
FIG. 3
, the parallel members
80
capture or mate with a portion of the twist-off member
25
and when the applicator head
26
is rotated relative to the solution container
21
, the twist-off member
25
is torn to provide an opening in the solution container
21
at the frangible portion
24
. Cross member
28
extends across the solution pathway
29
of the applicator head
26
and it can also be designed to be able to control the rate of fluid flow from the solution container
21
to the applicating material
31
. As shown in
FIG. 6
, there may also be apertures
78
that can also control the rate of flow of fluid and uniform distribution of solution to the applicating material
31
In a preferred embodiment, there are holes or apertures
34
through the receiving member
27
which are of sufficient size to allow enough solution to pass through the receiving member
27
to the applicating material
31
and also are of small enough size so that there is not too much solution going to the applicating material
31
.
FIGS. 4B and 5
show a portion of the solution container
21
with the twist-off member
25
, frangible area
24
and fluid path
37
(which is shown as the interior of the portion
36
that carries fluid from the container portion
91
of the solution container
21
to the frangible area
24
). For the embodiments in which the cap
22
is threaded to the container portion of the solution container
21
, protruding portion
38
forms a seal with the container portion
91
of solution container
21
to prevent leakage prior to the activation of the solution applicator
20
. Threads
39
engage with mating threads
82
of the container portion to lock the cap
22
and the container portion
91
together to form the solution container
21
.
Another preferred embodiment of a solution applicator
40
is shown in
FIGS. 7-13
. The solution applicator
40
includes a solution container
55
having a frangible twist-off member
52
and an applicator head
47
that engages with the solution container
55
such that the frangible twist-off member
52
is torn when the solution container
55
is rotated relative to the applicator head
47
. The solution is contained in the solution container
55
which can be formed in various shapes, including the oval-shaped solution container
55
shown in
FIGS. 7-9
and
12
. The solution container
55
is preferably locked in place to the applicator head
47
by having a lip
96
formed around the circumference of segment
42
of the applicator head
47
which mates with a holding ring
88
(see
FIG. 12
) that is like a channel around the circumference of the solution container's
55
circumference into which the lip
96
snaps to thereby put the applicator head and the solution container in locking engagement with each other. This lip
96
and channel
88
provide a sealed connection between the applicator head
47
and solution container
55
so that the solution does not escape between the applicator head
47
and solution container
55
. The engagement between the lip
96
and channel
88
allow rotation of the applicator head
47
relative to the solution container
55
, so that the twist-off member
52
can be torn to create an opening to allow solution to flow from the solution container
55
to the applicating material
65
on the end of the applicator head
47
.
The applicator head
47
has a receiving member
53
(as shown in
FIGS. 10
,
10
A and
10
B) that receives the twist-off member
52
such that twisting of the applicator head
47
(and therefore receiving member
53
) relative to the solution container
55
(and therefore twist-off member
52
) will cause the twist-off member
52
to tear an opening in the solution container
55
to thereby allow solution to flow from the solution container
55
into the applicator head
47
. The receiving member
53
also may have apertures
59
therethrough that help control the flow of fluid past and through the receiving member
53
so that the solution can flow to the applicating material
65
. The solution applicator
40
may also contain indicia
13
,
97
which indicate to the user that the user needs to rotate the applicator head
47
relative to the solution container
55
such that the indicia
13
,
97
are aligned, which is a signal to the user that the twist-off member
52
has been twisted enough to break it so that there is an opening in the solution container
55
to release the solution into the applicator head
47
. Indicia
13
,
97
may be holes, markings, words, protrusions and various other suitable types of indicia that will enable a user to know when the rotation has been sufficient to tear or break the twist-off member
52
. Solution container
55
may also be squeezable so that a user can squeeze the solution container
55
to increase the flow of solution to the applicator head
47
.
The parts of the solution applicator
40
may be made of numerous types of plastic materials including high density polyethylene, polypropylene, low density polyethylene or polyvinyl chloride (PVC). The solution container
55
preferably has a grip portion
41
that a user can easily grasp the solution container
55
to rotate it relative to the applicator head
47
.
In another preferred embodiment, the twist-off member
52
may also have a retainer mechanism
92
as shown in
FIG. 12A
that allows the twist-off member
52
to slide into the receiving member.
53
and then the retainer mechanism
92
expands such that the twist-off member
52
cannot be pulled back from the receiving member
53
. This helps hold the solution container
55
together with the applicator head
47
. In a preferred embodiment, said retainer mechanism
92
is V-shaped with a spring force such that the legs of the V squeeze together when the retainer mechanism
92
and the twist-off member
52
start to be inserted into said receiving member
53
. The legs of the V spring apart when said retainer mechanism
92
is fully inserted into said receiving member
53
to thereby hold said applicator head
47
and said solution container
55
together. The retainer mechanism
92
is preferably part of the twist-off member
52
. The retainer mechanism
92
can be molded as ribs coming off the end of the break off section of the twist-off member
52
, so that after pushing the end part of the solution container that contains the twist-off member
52
into the applicator head
47
, the ribs of the retainer mechanism
92
lock in place into the receiving member
53
making it impossible for the applicator head to be removed from the solution container prior to activation (twisting and breaking the twist-off member
52
). It is preferable that the retainer mechanism
92
be formed of the same material as that of the twist-off member
52
.
The applicator head
47
preferably has a solution pathway
50
that enables solution to flow from the opening from the torn twist-off member
52
past the receiving member
53
on through the applicator head
47
to the applicating material
65
, which is attached to flat end
48
of the applicator head
47
. The flat end
48
and the applicating material
65
are preferably formed at an angle as shown in
FIGS. 9 and 10
to make them ergonomically designed for the user. The flat end
48
with an orifice
49
therethrough is shown in FIG.
11
. The orifice
49
may be of various sizes and could have a number of smaller holes therethrough to obtain a suitable flow rate of the solution to the applicating material
65
. The applicating material
65
is attached to the flat end
48
and the flat end
48
may have radial slots
89
to allow solution to flow evenly to the applicating material
65
.
The twist-off member
52
is preferably a tab that extends outwardly from the solution container
55
and that is connected to the rest of the solution container
55
by a frangible web
99
that will tear when the tab is twisted off or twisted to break. This frangible web
99
is designed so that when the twist-off member
52
is twisted or rotated, the frangible web
99
will tear open to provide an opening for the solution to flow out of the solution container
55
. It is preferable to have the frangible web
99
be somewhat thinner than the walls of the rest of the solution container
55
so that it tears more easily at the location of the frangible web
99
. Ring
90
helps retain solution in the applicator head
47
so that it does not get on the user's hands near channel
88
.
