Title:
CARRIER BAG WITH COLLAPSIBLE FRAME
Document Type and Number:
WIPO Patent Application WO/2003/055762
Kind Code:
A1
Abstract:
A form of packaging, based on a standard box shaped collapsible carrier bag, with a lid for the carrier bag already attached to one side of the two longer sides. The lid of the carrier bag has tabs on with adherent properties to allow it to be fixed to the other three sides of the bag. A collapsible ridgid frame is mounted around the inside of the top of the carrier bag, to allow pressure to be applied to the tabs on the lid, to seal the lid to the other three sides of the carrier bag to form a sealed package.(use Figure 1)

Claims:
Claim
1. 1) A form of packaging using a traditional box shaped carrier bag, with a lid attached to one side of the bag, and tabs for attachment to the other three sides, with a collapsible rectangle frame fixed around the inside of the bag at the top, as shown in figure 1.
2. The frame as claimed in Claiml is attached to two parallel sides of the bag, and the other two sides hinged at the end of the attached sides as shown in figures 14, to allow the package to collapse in to a flat pack to facilitate storing of this packaging for selling purpose.
3. A package as claimed in any preceding claim which when opened out from a flat pack, then the frame facilitate a lid to the carrier bag, to come across and be sealed down, by the use of tabs on the lid, with built in adhere properties (adhesive strip, Velcro etc).
4. A package as claimed in any preceding claim that allows the tabs on the lid to exert pressure for sealing the package by applying the pressure against the rigid rectangular frame, thus keeping the box shape and not collapsing under the pressure of adhering.
5. A framework as claimed in any preceding claim, is one of four basic designs a) The two long sides fixed to the top of the inside of the bag, the other two sides fixed by hinges to the end of one of the long sides, as the bag is opened these two sides open out to lock the frame into a rigid rectangle. See figure 3 of Diagrams b) A one piece frame hinged at 6 points, the two long sides fixed to the top of the inside of the bag, and the two shorter sides opening up concertina style in the direction of the large thick arrows and locking out when the bag is fully opened. (See figure 4 of diagrams) c) A one piece frame hinged at 6 points, but dropping down into the bag, the two long sides fixed to the top of the inside of the bag, and the two shorter sides opening and locking out when the bag is opened. See figure 5 and 6 of diagrams d) A two piece assemble frame consisting of one horizontal strip attached to the top of one of the long sides of the bag, and the other assembly which is attached to the other long side of the bag hinged at two places so that a U shaped assembly drops down into the bag, when the bag is closed, and opens upwards and locks on to the long strip when the bag is opened See figure 7 and 8 6) To support a longer span, and to reduce flexing in the centre, extra brace can be added to the centre of the longer side of the frame, to open up, after the contents of the bag is opened, as shown in figure 9. This strut GH hinged at point G, locking out on the other parallel side AB at point I.
6. A framework as claimed in any preceding claim to form a rigid rectangle when the bag is opened, the said framework can be made of any suitable material, strong enough to resist the bag collapsing when the pressure of sealing the lid tabs to the carrier bag. The hinges can be any sorts of hinges suitable for the material chosen for the frame. Also the locking out mechanism for when the bag is opened can be any sort of locking out mechanism chosen for such material.
7. A packaging as claimed in any preceding claim, made of any material, for various purposes required by the manufacturer. I. e. Gift wrapping, Secure Document, Protecting components, general secured items.
Description:
CARRIER BAG WITH COLLAPSIBLE FRAME This invention relates to a new form of packaging for wrapping presents ready for placing under the Christmas tree, or for wrapping items in a secure package.

Background of the invention Nearly everyone has encountered the difficulties of buying presents and going home, sneaking up stairs and wrapping them up with wrapping paper, sellotape and scissors whilst locked in a room so the receiver of the present cannot see the contents, or travelling to a party and trying to buy a present, and gift wrap it whilst on the way to the party in a car. Decorative carrier bags are unsuitable because they display the contents of the carrier bag, taking away from the surprise element of the gift.

Description This invention is a ready wrap parcel for both presentation and industrial purposes, ready made in various sizes. The exterior of the parcel can be of plastic or paper or padded for insulation or protection, of plain or decorative nature, and consists of the standard collapsible box carrier bag with a pull over self-adhesive top, already fixed to one long side of the bag.

To ensure that the top can be adhered to the collapsing other three sides of the bag, a rigid strip is fixed around the top of the bag to form a rigid box, which will allow pressure to be applied when adhering the top to the other sides.

The rectangular box strip is hinged at various places to allow it to collapse within the bag into a flat pack carrier bag for selling and storing.

When somebody wishes to make a sealed parcel or present, then the bag is opened and the top opened out and locked into a rectangle. The contents inserted and the lid already attached to one side of the bag, is brought across the top and stuck down to form a seal on the three remaining sides with either strong self adhesive strips or lick-able adhesive.

This means that Christmas presents can be packed and sealed in the Package ready to be placed under the Christmas tree without the need of scissors and wrapping paper.

However, the Package has many applications for sealed parcels, for both presentation and industrial purpose.

Detail The Package is a standard box carrier bag, with a lid and a small framework around the top to allow pressure to be put to the carrier bag for the lid to be sealed down.

See Figure 1. (For clarity of the drawings, the handle of the carrier bags are not displayed on the drawings, and are optional on the invention) The rigid framework is collapsible for selling, and when open it locks the top of the carrier bag into a rigid rectangle The framework going around the top of the bag is attached to the bag at along the length A-B and D-C.

When the carrier bag is closed sides A-C and B-D collapse to allow AB and DC to meet in the middle, when the carrier bag is open, it forms rigid rectangle at the top of the carrier constrained by the shape of the carrier bag.

See Figure 2.

There are four ways that the framework can open up:- 1) See Figure 3.

They can be hinged at Points A and B and lock out at points C and D held in position by the pressure of the carrier bag confining the frame work 2) See Figure 4.

It can be hinged at all points A to F and opens up in the direction of the large thick arrows, locking out at points E and F 3) See Figure 5 & 6 Hinged at all points A-F and collapses downwards into the bag at points E and F when the bag is closed, and opens up in the direction of the arrows, locking out at EandF 4) See Figure 7 & 8 Two separate assemblies, ABFE and CD attached along the long two sides at the top of the bag (AB and CD), a U shaped frame hinged at points A and B, dropping down into the bag when the bag is closed. When the bag is opened the U shape frame swings upwards so sides EF locks up with sides CD to form-a rigid rectangle In the case of a larger carrier bag, extra supportive struts can hinged to one of the fixed sided sides if the frame, which opens up after the contents has been added into the bag, supporting the rigidity of the frame across the centre of the bag.

This strut G-H is shown on Figure 7, hinged at point G, locking out on the other parallel side AB at point I.
