Description

James & Wells Ref: 44200/14AJC 554833 PATENTS FORM NO. 5 Fee No. 4: $250.00 PATENTS ACT 1953 COMPLETE SPECIFICATION After Provisional No: 554833 Dated: 30 April 2007 PACKAGING CARTON WE Intellectual Property Energy Mad Ltd, a New Zealand company, c/o Grant Thornton, Level 9, Anthony Harper Building, 47 Cathedral Square, ChristchUrch 8011, New Zealand hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed to be particularly described in and by the following statement: 2 8 Jilt 554833 PACKAGING CARTON TECHNICAL FIELD The present invention relates to a packaging carton. In particular, the present invention relates to packaging cartons suitable for light bulbs, or other small 5 devices.

BACKGROUND ART For ease of reference only the present invention will now be described in relation to packaging containers suitable for light bulbs. However, this should not be seen as limiting the scope of the invention which may also have application to packaging 10 cartons for other items.

The packaging of light bulbs can be problematic as a number of factors must be taken into account including: - the fragile nature of light bulbs; - the type of light bulb (e.g. energy efficient, halogen, frosted glass, or clear 15 glass); - the style of light bulb; - the type of socket into which the bulb can be attached.

In addition, consumers typically want to see, the actual bulb itself and electrical fitting type of the bulb, to visually confirm its suitability for their needs. This 20 additional requirement therefore presents a further problem when considering the packaging of the bulb itself.

Thus, conventional light bulb packaging whilst addressing some of the above 2 James & Wells Ref: 44200/14AJC 554833 factors still have a number of draw backs which can include one or more of the following: - the type of bulb is not visible from within the packaging; - the type of socket into which the electrical fitting of the bulb is adapted to 5 engage is not visible from within the packaging; and/or - the packaging of the bulb does not allow for packaged bulbs to be easily stacked upon one another in a substantially stable manner.

It is an object of the present invention to address the foregoing problems or at least to provide the public with a useful choice.

Further aspects and advantages of the present invention will become apparent from the ensuing description which is given by way of example only.

All references, including any patents or patent applications cited in this specification are hereby incorporated by reference. No admission is made that any reference constitutes prior art. The discussion of the references states what 15 their authors assert, and the applicants reserve the right to challenge the accuracy and pertinency of the cited documents. It will be clearly understood that, although a number of prior art publications are referred to herein, this reference does not constitute an admission that any of these documents form part of the common general knowledge in the art, in New Zealand or in any other country.

It is acknowledged that the term 'comprise' may, under varying jurisdictions, be attributed with either an exclusive or an inclusive meaning. For the purpose of this specification, and unless otherwise noted, the term 'comprise' shall have an inclusive meaning - i.e. that it will be taken to mean an inclusion of not only the listed components it directly references, but also other non-specified components 25 or elements. This rationale will also be used when the term "comprised' or 3 James & Wells Ref: 44200/14AJC 554833 'comprising' is used in relation to one or more steps in a method or process. DISCLOSURE OF INVENTION According to one aspect of the present invention there is provided a packaging carton which includes: • a main body having at least one aperture therein; and • an open end portion which can receive and display a portion of the packaged item; the carton characterised in that the open end portion is surrounded by a wall or walls which terminate(s) with a horizontal section of greater dimensions than the 10 thickness of the wall(s).

In preferred embodiments the packaged item may be a light bulb.

For ease of reference the packaged item will now be referred to as being a bulb.

However, this should not be seen as limiting the scope of the present invention as the features of the present invention may also have application to packaging other 15 items.

It is envisaged that the packaging carton may generally be made from cardboard or other paper based types of material. However, this should not be seen as limiting the scope of the present invention.

The main body of the carton may have a variety of different shapes and 20 configurations without departing from the scope of the present invention.

In some embodiments the main body may have at least one circular wall.

In some embodiments the main body may have at least three walls. 4 James & Wells Ref: 44200/14AJC 554833 In preferred embodiments the main body may have four walls.

In some embodiments the aperture may be in at least one wall of the main body.

In some embodiments where the main body is formed via a circular wall there may be provided substantially opposed apertures in the main body.

In preferred embodiments there may be provided two apertures located in opposed walls of the main body section.

It will be understood that the size of the aperture may vary.

In general the size of the aperture may be sufficient so as to view the type and style of bulb located within the main body of the packaging carton.

In further preferred embodiments the size of the aperture may be substantially in the region of 30-70% of the wall in which it is located.

Preferably, the apertures in opposed walls may be substantially aligned with one another. However, this should not be seen as necessarily limiting as in some embodiments the apertures may be positioned within opposed walls so that, 15 although not perfectly aligned with one another, a substantial portion of each aperture overlaps with the other aperture.

The main body also includes a closure flap located at one end of one wall. In use, the closure flap can be opened to receive the packaged item and then closed to retain the packaged item within the main body.

The main body also includes a second flap which has an aperture therein through which a portion of the packaged item, in use, can protrude, or at least be viewed, from the open end portion.

In preferred embodiments the size of the aperture in the second flap is James & Wells Ref: 44200/14AJC 554833 dimensioned so as to be smaller than that of the cross sectional dimension of the packaged item so that the item can be retained within the main body of the carton.

In preferred embodiments the end of the walls of the main body opposite the closure flap terminate with a horizontal section. The advantage of this configuration 5 is that it allows for one piece construction of the carton, However, in some embodiments it should be appreciated that the opened portion could be created with its own walls which are independent of the walls of the main body.

In preferred embodiments the second flap may be configured to create one of the 10 horizontal sections of the open end section.

In such preferred embodiments the second closure flap may be folded to: - sit a set distance below the horizontal sections of the open end portions; and - create a horizontal section at the terminus of one wall.

In preferred embodiments the width of the horizontal sections is sufficient to support in a stable manner at least one, but preferably two, carton(s), placed thereon to form a stack.

In some embodiments there may be up to around four cartons in a stack.

The remaining flat sections may be formed by flaps formed by the end regions of 20 the other walls, which are folded back to form the horizontal section, as well as a new vertical section. Thereby effectively reinforcing the strength of the walls of the open end section.

In general the width of each horizontal section should be at least substantially 8% Intellectual Property Office of N.2. 2 8 APR 2008 ■tarn ' V fc James & Wells Ref: 44200/14AJC 554833 of the width of the carton, The open end portion may, in preferred embodiments, have a number of wall flaps which help support the horizontal section.

In preferred embodiments the carton may also include an insert section which fits within the main body.

In some preferred embodiments the insert section may be a folded sheet of material which encases the object to be packaged on at least two opposable sides. In use the insert is positioned so that the non-encased sides of the item are aligned with the apertures in the walls of the main body.

In some further preferred embodiments the insert section may be a different colour 10 to the packaging. As coloured insert sections can help provide a contrast to allow for better viewing of the packaged item within the carton.

In some even further preferred embodiments the insert section may include one or more apertures as required to allow for a flush fit against the inside surface of the walls of the main body.

Thus, preferred embodiments may have a number of advantages over the prior art which can include: • an improved packaging carton which takes into account such things as: the fragile nature of light bulbs; the type of light bulb; the style of light bulb; and the type of socket into which the bulb can be attached. 7 James & Wells Ref: 44200/14AJC 554833 • an improved packaging carton wherein consumers can see the actual bulb itself and electrical fitting type of the bulb. • an improved packaging carton as detailed above which which allows for ease of stacking.
