COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it
is to be performed.

Technical Field
[0001] The subject matter described herein, in general, relates to plugs for bottles,
and in particular to plugs that may act as couplers.
Background
[0002] Bottles may be used to hold various contents, such as liquid or solid
contents, during use and transportation. Sometimes, various devices may have to be coupled to the bottle. For example, a bottle holding a vaporizable liquid, such as a perfume, an insect repellant, or the like, may have to be coupled to a vaporizer machine for heating the vaporizable liquid. Typically, the bottle itself is molded in such a way that it may include a coupling portion to couple with the device. For example, a bottle may be provided with threads on a neck region which may couple to corresponding threads on a machine.
Brief Description of Drawings
[0003] The following detailed description references the figures, wherein:
[0004] Fig. 1 illustrates a bottle plug, in accordance with an example
implementation of the present subject matter.
[0005] Fig. 2 illustrates a plug bottle assembly, in accordance with an example
implementation of the present subject matter.
[0006] Fig. 3 illustrates the plug bottle assembly including a wick, in accordance
with an example implementation of the present subject matter.
Detailed Description
[0007] Various plugs are known for closing or sealing bottles to avoid spillage of
their contents and prevent ingress of contaminants. Sometimes, the plug may have a provision or opening for accessing the contents. In case of bottles that contain vaporizable

liquid, such as perfume or insect repellant, a wick is passed through an opening in the plug and into the bottle to allow the liquid to rise through the wick. When the bottle is coupled to a vaporizer machine, the top end of the wick which is outside the bottle is in the vicinity of a heating element provided in the vaporizer machine and the heat causes the liquid to vaporize. The bottom end of the wick remains immersed in the liquid inside the bottle until the liquid level falls to a height below the bottom end of the wick. For coupling the bottle with the machine, the bottle is provided with a coupling portion having threads that can be coupled to corresponding threads provided on the machine. Since the coupling portion on the bottle is fixed, it can be coupled only to certain compatible machines, thereby, restricting interchangeable usage of bottles and machines. Moreover, the flexibility for producing and using various coupling arrangements is low.
[0008] The present subject matter addresses these problems and other
deficiencies of conventional bottle plugs and provides bottle plugs that may be connectable to a bottle. The bottle plugs may be used for coupling and may provide flexibility in coupling with various kinds of machines.
[0009] In one example, the bottle plug may include a plug body, a first connecting
portion provided on a first end of the plug body, and a second connecting portion provided on a second end of the plug body that is opposite to the first end. The plug body may be a hollow cylindrical structure to allow a wick to pass through it. The first connecting portion may be a hollow cylindrical structure of a diameter smaller than the diameter of the plug body. The first connecting portion may be adapted to be placed inside a bottle opening of the bottle in a tight fitting arrangement to arrest leakage of a liquid contained in the bottle. The first connecting portion may further be adapted to hold the wick in a substantially vertically straight position.
[0010] Further, the second connecting portion, in one example, may include
coupling structures for detachably coupling the bottle with a bottle receiver, for example a liquid vaporizing machine. In one example implementation, the second connecting portion may further include a flange that may be adapted to sit over a rim of the bottle. The flange may include a coupling unit adapted to detachably couple the bottle with a receiving unit of the bottle receiver. In one example, the coupling unit may include one or more wings extending from the flange in opposite directions outwardly of the plug body.

The one or more wings, hereinafter interchangeably referred as wings, may help to couple the bottle with the receiving unit, for example a bayonet receiver portion, on the bottle receiver. In other examples, the second connecting portion may include other coupling structures for coupling with corresponding coupling mechanisms on machines. For example, the coupling unit may include a threaded portion, one or more grooves, a clip, the one or more wings, or a combination thereof, for detachably coupling the bottle with the receiving unit.
[0011] Thus, depending on the coupling mechanism provided in the bottle receiver,
hereinafter interchangeably referred to as machines, the second connecting portion may
be suitably modified to allow the bottle to be detachably coupled with the machine.
Accordingly, without changing the bottle mold or manufacturing process, the bottles can
be made suitable for coupling with different coupling mechanisms provided on different
machines by changing the bottle plug, hereinafter interchangeably referred to as plug.
[0012] Thus, the present subject matter provides for a dual purpose plug that can
act both as a leakage arrester and as a coupler to fix the bottle into the receiving unit, for
example, a bayonet mount receiver, of the bottle receiver. Examples of the bottle receiver
may include, but are not limited to, liquid vaporizing machine, room fresheners, spray
bottles, an atomizer, and other gaseous and liquid spraying machines. Moreover, it
provides agility in fastening by providing the coupling unit, for example, the wings on the
flange of the plug. Further, the modified plug enables a reduction in amount of plastic
used in the bottle. It also avoids redesign of bottle molds and change in bottle
manufacturing process in case the coupling mechanism on the machine is to be changed.
[0013] The above and other features, aspects, and advantages of the subject
matter will be better explained with regard to the following description and accompanying figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter along with examples described herein and, should not be construed as a limitation to the present subject matter. It is thus understood that various arrangements may be devised that, although not explicitly described or shown herein, embody the principles of the present disclosure. Moreover, all statements herein reciting principles, aspects, and examples thereof, are intended to encompass equivalents

thereof. Further, for the sake of simplicity, and without limitation, the same numbers are used throughout the drawings to reference like features and components.
[0014] Fig. 1 illustrates a bottle plug 100 in accordance with an example
implementation of the present subject matter. The bottle plug 100 may be adapted to connect with a bottle. The bottle plug 100 may include a plug body 102, a first connecting portion 104 provided on a first end 106 of the plug body 102, and a second connecting portion 108 provided on a second end 110 opposite to the first end 106. The plug body 102 may be a hollow cylindrical structure to allow a wick (not shown in this figure) to pass through it.
[0015] The first connecting portion 104 may be a hollow cylindrical structure of a
diameter smaller than the diameter of the plug body 102. In one example, the plug body 102 may taper at the first end 106 where the first connecting portion 104 is formed. The plug body 102 and the first connecting portion 104 may be adapted to be placed inside a bottle opening in a tight fitting arrangement to arrest leakage and to hold the wick in a substantially vertically straight position.
[0016] The second connecting portion 108 may include coupling structures for
detachably coupling the bottle with a bottle receiver (not shown in the figures). In one
example, the second connecting portion 108 may include a flange 112 that may be
adapted to sit over a rim of the bottle. In one example, the second connecting portion 108
may include one or more wings 114-1 and 114-2, hereinafter referred to as wings 114,
extending from the flange 112 in opposite directions. The wings 114 may help to couple
the bottle with a receiving unit, such as a bayonet receiver provided on the bottle receiver.
Examples of the bottle receiver may include, but are not limited to, mosquito repellent
liquid vaporizers, fragrance vaporizers, steamers, and other vaporizing devices.
[0017] In other examples, the second connecting portion 108 may include other
coupling structures for coupling with corresponding coupling mechanisms on machines. For example, the second connecting portion 108 may include a clip or a threaded neck or other such coupling structures instead of or in addition to the wings 114.
[0018] In various examples, the bottle plug 100 may be made of a polymeric
material, such as an elastomer or a rigid polymer, to allow for tight fitting of the bottle plug 100 with the bottle and the wick and for robust coupling with the machine.

[0019] Fig. 2 illustrates a plug bottle assembly 200, in accordance with an example
implementation of the present subject matter. In one example, the plug bottle assembly 200 may include bottle plug 100 coupled with a bottle 202. In one example, the bottle 202 may contain a liquid to be vaporized when the bottle 202 is connected with the bottle receiver, such as a vaporizing machine. Examples of the liquid may include, but are not limited to, fragrances, mosquito repellents, and water.
[0020] As shown, the bottle plug 100 may be placed in the bottle 202 such that the
first connecting portion 104 is placed inside the bottle 202 while the second connecting portion 108 sits on the rim of the bottle 202. The second connecting portion 108 may include coupling structures for coupling the bottle 202 with a receiving unit of the bottle receiver. In one example, the second connecting portion 108 may include a flange 112 that may be adapted to sit over the rim of the bottle 202. In one example, the second connecting portion 108 may include one or more wings 114 extending radially on opposite sides of the flange 112. The bottle plug 100 thus acts as a cylindrical male side with the radial wings 114 protruding out of the flange 112. The wings 114 may be received by the receiving unit and may thus help in detachably coupling the bottle 202 with the receiving unit, such as a bayonet receiver, provided on the bottle receiver. The bottle receiver may interchangeably be referred to as a machine, a device, or a vaporizer. In one example, the second connecting portion 108 may include two wings 114 spaced apart by an angle of 180 degrees. In other examples, the number and placement of the wings 114 may be adapted as per the bayonet receiver provided in the machine.
[0021] In one example, the bottle 202 may also include a threaded portion 204 to
allow the bottle 202 to couple with the receiving units of the machines that may have compatible threads for screw-type coupling. In other examples, the bottle 202 may not include the threaded portion 204. The wings 114 may be flexible and designed in such a way that the wings 114 can flex-down itself while coupling the bottle 202 to a machine/device with screw-type coupling using the threaded portion 204. Thus, interference from the wings 114 can be avoided in such cases where the wings 114 are not used for coupling.
[0022] Typically, vaporizer machines found in market have a thread type receiving
unit or a bayonet mount receiver. By providing a plug having wings on a flange and that

is connectable to a threaded bottle, the present subject matter allows refill bottles with
vaporizer liquid to be coupled to any type of machine. The plug with wings can fit with
bayonet mount while the thread in neck of bottle can fasten with a thread mount.
[0023] Thus, the present subject matter provides a universal fitment of the bottle
to machines/ devices having screw type receiver as well as bayonet mount receiver, thereby giving a freedom to consumer to couple the bottle with any type of device available in market. The present subject matter further helps in a quick switch over of coupling mechanism for any new design as making a design change in plug is easy and low investment at reduced complexity than to have design change in bottle. Furthermore, the present subject matter may also facilitate in reducing usage of plastic in bottle manufacturing as the bottle mold need not be made complex.
[0024] Fig. 3 illustrates the plug bottle assembly 200 including a wick 304, in
accordance with an example implementation of the present subject matter. As discussed in Fig. 1 and Fig. 2, the bottle plug 100 may include a plug body 102. In one example, the plug body 102 may be a hollow cylindrical structure 302 to receive a wick 304. Diameter of the hollow cylindrical structure 302 may be accordingly adapted, for example at the time of manufacturing the plug body 102, to securely fit the wick 304 having a diameter within a defined range. The hollow cylindrical structure 302 may allow at least a portion of the wick 304 to pass through the plug body 102. Further, the first connecting portion 104 may be adapted to be placed inside the bottle opening to hold the wick 304 in a substantially vertically straight position. In one example, at least a portion of the wick 304 may extend out of the bottle 202 in order to get in contact with the bottle receiver or the machine to vaporize a liquid contained in the bottle 202. In one example, the machine may thermally couple with the liquid, through the wick 304, to vaporize the liquid stored in the bottle 202.
[0025] For illustration purposes, the wick 304 has been illustrated as a cylindrical
structure, however, the wick 304 may also be provided in different designs. For example, the wick 304 may be of a cuboidal or a 3D rectangular structure. Based on the structure of the wick 304, the hollow cylindrical structure 302 may accordingly be adapted to securely fit the wick 304. For example, for a cuboidal shaped wick, the hollow cylindrical

structure 302 may be modified into a square/rectangle shaped hollow structure of
appropriate size to receive the cuboidal shaped wick.
[0026] Although various implementations for bottle plugs are described, it is to be
understood that the present subject matter is not necessarily limited to the specific
features described. Rather, the specific features are disclosed as example
implementations.
