Description

The invention is directed to a confection package comprising of a plastic mould product having a space for a confection filled with a freezable or frozen confection and a space for one end of a handle. The space for the confection and the space for one end of a handle are positioned below a planar surface and a planar cover sheet is sealed to the planar mould product.

GB20175327 describes such a confection package wherein the space for the confection and the space for one end of a handle are fluidly connected. The confection as present in the space for the confection is in a frozen form and will therefore not flow into the space for the handle. A problem is that some of the frozen confection may enter the space for the handle. For example when it part of the confection melts.

Such a confection package is described in U.S. Pt. No. 4,001,440. This publication describes a confection package consisting of a chamber for a frozen confection provided with a handle. Such products are also referred to as ice lollypops. The chamber for the frozen confection has an outer appearance of a character. The exterior part of the handle is placed in a slot. Slot and chamber for the confection are present in a single part of the package. A flat seal enclosed the chamber and slot of the package at their upper end. The handle is kept in its position by a peg present in the slot which locks with a similarly shaped aperture in the exterior part of the handle.

The confection package described in JPS54134184 describes a similar construction as in U.S. Pat. No. 4,001,440.

A disadvantage of the confection package of U.S. Pat. No. 4,001,440 is that liquid confection may flow into the slot before the confection is frozen in an industrial packaging process. This does not have a good appearance which is undesirable for a commercial confection package. The aim of the present invention is to provide a confection package which limits the risk that liquid confection flows towards the exterior part of the handle.

This is achieved by the following confection package comprising of

a plastic mould product comprising a space for a confection, a space for one end of a handle, and a horizontal planar surface, wherein the space for a confection is fluidly separated from the space for one end of a handle and wherein the space for one end of a handle and the space for a confection is positioned below the planar surface,

a planar cover sheet sealed to the planar surface of the plastic mould product,

a volume of a freezable or frozen confection as present within the space for a confection, and

a handle comprising of an interior part of the handle positioned within the volume of freezable or frozen confection in the space for a confection and an exterior part which in use will allow the volume of freezable confection to be manually held by a user and which exterior part is positioned in the space for one end of the handle, wherein the interior part is connected to the exterior part by means of an offset intermediate part, and wherein

part of the intermediate part of the handle is sealed at its upper end to the planar cover sheet and at its lower end to an upper end of a wall part of the plastic mould product which wall part horizontally separates the space for a confection from the space for one end of a handle and wherein the upper end of the handle is positioned above the planar surface.

Applicants found that by elevating the offset intermediate part to a position above the planar surface of the of the plastic mould product a liquid barrier results which avoids liquid confection to flow from the space for a confection to the space for one end of a handle.

The invention and further advantages will be further described below. In the description terms like upper, lower, horizontal, vertical, above and below refer to the preferred position of the confection package when it is filled with non-frozen confection. These terms used to describe the confection package more clearly and are not intended to limit the invention to only a confection package in this position.

The offset intermediate part of the handle may suitably consist of three bends, wherein a first bend is between the interior part and intermediate part directing the handle from the confection towards upper end of wall, a second bend at upper end directing the handle towards space for one end of a handle and a third bend connecting the intermediate part and the exterior part of the handle and directing the handle in the direction of the space for one end of a handle, wherein the second bend is comprised in the upper end of the handle.

Alternatively the offset intermediate part of the handle may suitably consist of at least four bends, wherein a first bend is between the interior part and intermediate part directing the handle from the confection towards the planar surface, a second bend which directs a horizontal part of the handle along the planar surface, a third bend which directs the handle towards space for one end of a handle and a fourth bend connecting the intermediate part and the exterior part of the handle and directing the handle in the direction of the space for one end of a handle and wherein the upper end of the handle is comprised in the horizontal part of the handle.

The handle may have any shape which makes the handle suitable to bond to the frozen confection and to be manually held by a user. Preferably the handle comprises an intermediate part and especially the earlier referred to horizontal part wherein intermediate part or horizontal part have a rounded upper surface and a flat lower surface. The upper rounded surface ensures an efficient sealing with the planar cover sheet and the flat lower part ensures a liquid barrier when this flat part rests on a preferred horizontal part of the wall part of the plastic mould product. Preferably the entire handle has a rounded upper surface and a flat lower surface.

The ice lollypop when removed from the confection package will for practical reasons have a handle with an exterior part extending away from the mass of confection. The interior part of the handle will suitably be present centrally or about centrally within the mass of confection. The interior part and the exterior part of the handle may extend in a parallel longitudinal direction. It is however not excluded that the interior part and the exterior part of the handle are positioned under an angle. A preferred handle has an interior part which is aligned with the exterior part of the handle. Even more preferably the interior part and the exterior part have the same shape such that the handle is shape symmetrical. Shape symmetrical handles are preferred because it simplifies the automatic placing the handles in the plastic mould product. Namely a so-called pick and place machine, which may be used for placing the handles, does not have to direct the handle in one direction but can randomly position the handle in the space for one end of the handle and in the space for a confection.

The interior part and the exterior part of the handle are provided with one or more snap-fit type connectors. Any openings or extensions on the surface of the interior part of the handle may ensure a more intimate bonding of the convection with the handle. The snap-fit type connectors have the advantage in that the user can play with the handles by connecting more than one handle after consuming the confection. This is favourable for the environment because the user will more likely keep the handles and not through them away and pollute the environment. The connector preferably consists of a male type element with a female type element which can connect in a snap-fit manner. Such connectors are well known and for example described in GB866557, U.S. Pat. No. 3,005,282, U.S. Pat. No. 4,552,541, U.S. Pat. No. 4,744,780, U.S. Pat. No. 4,919,635, U.S. Pat. No. 5,230,195, U.S. Pat. No. 4,718,08, US2011045733, US2016263489 and US2014227937. The male type element is preferably an extension present at the upper and/or lower side of the handle and has a cylindrical or frusto-conical outer surface. The female type element may be any design opening which can receive the male type element and result in a snap-fit connection with such a male type element. The connectors are preferably spaced such that different arrangements between more than one handle are possible. The snap fit connection is preferably such that it also allows pivoting along the connection when two handles are connected by means of one snap-fit connection.

Suitably an air gap is present between the exterior part of the handle and the bottom of the space for one end of a handle. This avoids that the handle can freeze to the bottom of the space for one end of the handle.

The freezable confection may be frozen or non-frozen. The confection package may be stored and distributed at ambient temperature wherein the confection is not frozen. The end user may for example freeze the non-frozen confection just before consumption at her or his one home. Because the space for a confection and the space for one end of a handle in the plastic mould product are fluidly not connected any risk that liquid confection flows into the space for one end of a handle is low.

The plastic mould product may be made of polymer materials, such as those made from polyester, polyolefin, polypropylene, polystyrene and polyimide. Especially preferred are co-extruded sheets of amorphous polyester and polyolefin, such as that sold under the Registered Trademark MP 300 (Wipak, Poland). The planar cover sheet may be a plastic film, for example a polyester film, especially a biaxilally-orientated polyester film such as the one sold under the registered trademark BIAXER (Wipak, Poland). The film mat be metallised with for example aluminium to increase the insulating properties of the package.

The invention is also directed to a process to prepare a confection package according to the invention. The process comprises the following steps:

(i) combining a handle with a plastic mould product having a space for a confection, a space for one end of a handle, and a horizontal planar surface, wherein the space for a confection is fluidly separated from the space for one end of a handle and wherein the space for one end of a handle and the space for a confection is positioned below the planar surface,

(ii) adding a non-frozen freezable confection as a liquid to the space for a convection, and

iii) sealing a planar cover sheet to the horizontal planar surface of the plastic mould product and to the upper end of the handle.

Suitably in step (ii) the non-frozen freezable confection is added up to the level defined by the horizontal planar surface.

The plastic mould product may be made by any known manufacturing method, such as for example injection moulding, blow moulding or rotational moulding and is preferably manufactured by thermoforming using a film and a mould. The mould used may have any shape and may be made from any material. Typically such a mould is made from a metal and formed by subtractive manufacturing wherein the mould is manufactured by a controlled material-removal process using one or more machining tools. This method is time consuming and will preferably be used when making a mould suited to make large numbers of the same plastic moulded products. When one desires to manufacture plastic mould products according to the invention having varying designs in small numbers it is preferred to manufacture the mould by means of addition manufacturing, also referred to as 3D-printing. Applicants found that by using 3D printing it is possible to simply make a mould having a bespoke shape which can be economically used for making plastic moulded products in a relatively small number.

The above 3D printing is especially used in a method which allows a client located at their computer to transmit data via a data communication network to a computer under control of a manufacturer of the mould. The client computer could be a traditional desktop computer, a laptop, or tablet, or a mobile device such as a smart-phone, and preferably remote from the mould manufacturer's computer. The data transmitted across the network is a representation of the shape of the frozen confection and thus of the plastic moulded product. This could be in the form of a photograph or other 2-dimensional graphic to be interpreted by the mould manufacturer to form a 3-D model, or a digital representation of a 3-D model itself. The data communication network would typically be the Internet.

The supplier receives the data, which is then prepared for making the mould used in the thermoforming process. A stage of 3-D model optimisation may be included in the process, wherein the optimisation may comprise any one of the following steps:

i) Transformation of a 2-D representation of an object into a 3-D model. This could be carried out automatically with image processing software, or could include or consist of input from a human operative.

ii) Removal of undercuts in a 3-D model so produced, or received by the supplier, to ensure that the plastic moulded product can be readily removed from the mould after solidification.

iii) Removal of unwanted or unnecessary background information or image content that might otherwise lead to unwanted material at the edges of the plastic moulded product.

iv) Scaling of the 3-D model, either maintaining the aspect ratio in all three dimensions, or selectively scaling one or two dimensions such the 3D printing produces moulds that may be accommodated in the forming station and/or produces a desired mould volume.

Following optimisation of the 3-D model, a mould is created by the use of 3D printing. A number of 3-D printing technologies will be available to the skilled addressee, printing in a range of materials including plaster (e.g. with the 3-D printer sold under the Registered Trademark “ProJet® 660 Pro” by 3D systems Inc., USA), thermoplastics, photopolymerised polymers, or thermally-sintered materials. In particularly preferred embodiments, the mould is produced using thermal sintering (preferably by laser) of materials such as that sold under the Registered Trademark Alumide®, and comprising a powdered composition of polyamide and powdered aluminium. The inventors have found that such a process and material produce a mould that is particularly effective at resisting the temperatures applied in the thermoforming process.

When the mould is made by 3D printing using a material having a low thermal conductivity as described above it is preferred that the mould is provided with a number of openings which fluidly connect the side of the mould facing the mould product and the opposite side. The thickness of the mould is preferably between 0.5 and 5 mm. The holes are typically less than 2 mm in diameter, and preferably less than 1 mm in diameter. The openings allow air to escape through the mould during the forming process. The mould is further suitably provided with channels for passage of cooling air. Cooling of the mould enhances the moulded product to solidy into its desired shape in the mould.

To form a plastic mould product a sheet of thermoplastic material is placed over the mould and a pressure differential is created over the sheet material while the material is heated above its softening point. The pressure differential is typically created by use of a vacuum below the sheet with heating carried out by an infra-red source. The mould forming process is well-known in the art as vacuum forming. Particularly preferred materials for forming the moulded product are sheet polymeric materials, such as those made from polyester, polyolefin, polypropylene, polystyrene and polyamide. Especially preferred are co-extruded sheets of amorphous polyester and polyolefin, such as that sold under the Registered Trademark MP 300 (Wipak, Poland). The sheet materials preferably have a thickness of less than 1 mm and even more preferably between 100 and 500 microns.

The above described thermoforming process and the above described process to make the confection package is suitably performed in an automated thermoforming apparatus comprising of a plastic mould product forming station which provides the plastic mould product by thermoforming, a handle placing station, a non-frozen confection loading station, a sealing station and a cutting station.
