Abstract
Description
- The invention relates to an improved container for use with opening means. The invention further relates to a method of manufacturing said container. Although the following description refers to plastic blister pack containers and/or clam shell containers it will be appreciated by persons skilled in the art that the inventive concept herein can be used for a wide variety of containers, including those made from paper, card, foil, metal and/or the like and is not limited to plastic blister pack containers and/or clam shell containers.
- The use of plastic blister packs and clam-shells as containers is extensive. Such containers are routinely used to sell many different types of products such as electronic articles, for example disposable cameras, memory cards sticks, hard-drives; household articles including lightbulbs; small replacement parts for cars such as sparking plugs; children's toys and so on. Blister packs generally have a molded plastic front and a cardboard back. Clam-shells generally have a plastic front and back, one or both of which is molded. Both of these types of containers are generally described as preformed containers. These types of containers are usually thermoformed and/or heat sealed around the edges of the container defining an interior volume within the container in which is provided the product. Such containers have many advantages including being inexpensive, relatively easy to produce, strong, transparent and thus the contents can be readily viewed, and the forming process ensures that the surface container follows the shape of contents, thereby reducing the overall size of the container whilst being aesthetically pleasing. The containers, being sealed, also provide security for the contents as well as protecting said contents from exposure to moisture, static and general environmental conditions.
- A significant problem of such containers is that they are very difficult to open. Typically a sharp knife, scissor or specifically designed widget is used to open the containers which can injure the person and/or damage the contents. Opening such containers is particularly demanding for the elderly or infirm. Indeed, it has been reported that thousands of people every year need medical treatment after injuring themselves opening or attempting to open such containers. Furthermore, once the containers have been opened, the edges of the openings are usually sharp enough to cut a person and dangerous to children and domestic animals.
- It is therefore an aim of the present invention to provide a container which attempts to negate the abovementioned problems and allow the container to be easily opened in order to remove the contents provided within. It is a further aim of the present invention to provide a ne type of blister pack and/or clam-shell container that attempts to negate the abovementioned problems.
- According to one aspect, a container includes: at least one plastic surface, having a formation or step having a peripheral edge arranged around an area to be opened; and at least one second surface located in a region adjacent the first surface, and having a recess adjacent the formation on the plastic surface, wherein the first and second surfaces are sealed at arm edge of the container for securing an object located therebetween, and wherein the plastic surface and the second surface are configured such that in cross-section a channel is formed between the formation and the recess, and said formation and/or recess is configured to receive and/or guide a cutting edge for opening the container.
- According to another aspect, a container includes at least one plastic surface, having a step, formed by a recess or protrusion, having a peripheral edge arranged around an area to be opened. At least one second surface is also provided located in a region adjacent the first surface, and having a corresponding formation adjacent the recess or protrusion of the plastic surface. The first and second surfaces are sealed at an edge of the container for securing an object located therebetween, and the plastic surface and the second surface are configured such that in cross-section a channel is formed between the step and the formation. The channel is configured to receive a cutting edge for opening the container.
- The wall, or a portion thereof, of the step is thinner than the plastic surface such that it is easier to initiate a cut or tear in the container.
- In cross-section, the channel can have a quadrilateral profile. The profile shape can be continuous around the portion to be opened. The profile can be square or triangular. In cross-section, the channel can have a minimum dimension of 3 mm.
- The second interior surface can have a recess for locating an object therein. By way of example, the channel can be formed on three sides of the recess.
- The formation can have a raised portion configured to provide a void or air-gap above the second surface, and wherein the formation, in cross-section, has a groove.
- The formation can have a cross sectional profile having a channel arranged between two raised sections.
- The formation has a cross sectional profile in the form of the letter “M” from the Latin alphabet.
- The channel between the formation and the recess defines a void, or air-gap, which is configured to receive the tip of a cutting implement such that said tip is guide or retained therein.
- The groove or channel of the formation has tear-line and/or perforations.
- Overall, the formation is provided on the surface to form a channel having space beneath that can receive the end of an implement. When an implement, such as an edge of a knife, is pushed in to the formation it tears or cuts through the formation until the tip is located in the recess. Movement of the implement along the recess splits or divides the formation to open the container. This inhibits accidental or uncontrolled movement of the implement.
- The shape of the formation in cross-section is profiled to further secure the implement and further inhibit accidental or uncontrolled movement of the implement.
- By way of example, an M-shaped formation in a plastic surface can be formed having a space there beneath such that an implement penetrating the central groove of the M-shaped formation is located (i) between the edges of the M-shape and/or (ii) in a recess in the second surface.
- One or more of the plastic surfaces can comprise molded plastic. The container can be formed from a single piece or sheet of plastic.
- The container can be a molded blister pack type, or a molded clam shell type.
- The container can be adapted to guide a cutting edge protruding through said plastic surface of the container in the region of the step and passing through the plastic surface.
- The invention also relates to a method of manufacturing a container including: providing at least one plastic surface, having a step having a peripheral edge arranged around an area to be opened; and providing at least one second interior surface located in a region beneath the first surface, and forming a corresponding formation adjacent the recess or protrusion of the plastic surface; sealing the first and second surfaces at an edge of the container for securing an object located therebetween, wherein the plastic surface and the second surface are configured such that in cross-section a channel is formed between the step and the formation, and said channel is configured to receive a cutting edge for opening the container
- Typically the term “cut” refers to a break, split, incision, slice and/or the like of the plastic surface of the container.
- The container can be a pre-formed blister pack type container, pre-formed clam shell type container and/or the like. Preferably when the container is of a blister pack type, the one or more articles contained inside are located between one or more sheets of molded plastics material. Further typically at least one surface of the blister pack is formed from heat and/or vacuum molding a plastic sheet to closely fit the package contents to be located in the same in use.
- Preferably when the container is a clam shell type container, the one or more articles are held between two or more sheets of plastics material in use at least one of which is molded.
- Typically the plastics material is substantially includes Polyvinyl chloride (PVC), Polyethylene terephthalate (PET), polypropylene (PP), and/or copolymers of the aforementioned, and/or plastics material with similar characteristics. The container is typically constructed from plastics material that is relatively sturdy where the container is not intended to be opened by hand.
- It will be appreciated by those skilled in the art that opening means can be attached to the surface in any shaped path and thus the resulting cut-line can also be in any shape corresponding to the path.
- The channel of the invention can form a groove, which can be a corner in a recess of a surface of the container. The groove can be internal, located between the surfaces of the container. The container can contain one or more channels or grooves that substantially guide the opening means.
- The channel can define an interior volume along which the opening means is guided. The channel may be located separately from the molded interior volume provided to contain product. The channel can extend along a substantial section of one surface of the plastic container forming essentially a “U” or “C” shape. The channel can be between 1-5 min wide and 3-1.0 mm deep.
- The groove and/or channel can allow selective sectional opening of a container which has more than one section. Typically this is for use when opening a pack or container containing more than one item, where only a portion of the total items are used at a time and the container is retained to store the remaining items. Further typically when the retained items are required the user simply moves the opening means further through the container to open a further section.
- In order that the invention can be more readily understood, reference will now be made, by way of example, to the drawings in which:
-
FIG. 1 is cross-sectional view of a container in accordance with the invention; -
FIG. 2 is a plan view of a container in accordance with the invention; -
FIGS. 3a and 3b are plan views of a container having formation patterns, whileFIG. 3b is a close-up of an overhang at a corner of a formation; and -
FIG. 4 is a cross-sectional view of a formation on plastic surface. - It will be appreciated by those skilled in the art that the improved container formations are applicable to wide number of difficult to open configurations which are not intended to be opened easily and/or by hand.
- Referring to
FIG. 1 , acontainer 10 has aplastic surface 12 having a step orformation 14, in the form of a recess or protrusion, or having a recess. The formation has aperipheral edge 16 arranged around an area to he opened 18. Asecond surface 20 is located in a region adjacent, or beneath the first surface, as viewed, and having acorresponding recess 22 adjacent theformation 14 of the plastic surface. Therecess 22 is optional, and thesecond surface 20 can be flat beneath theformation 14. The first and second surfaces are sealed at anedge 24 of the container for securing an object located therebetween. The plastic surface and the second surface are configured such that in cross-section a channel or void 26 is formed between thestep 14 and the second surface orformation 22, and saidchannel 26 is configured to receive a cutting edge (not shown) for opening the container. -
FIG. 2 shows a plan view of a container wherein thestep 14 andperipheral edge 16 are located proximal theedge 24 of thecontainer 10. - The features of
FIGS. 1 and 2 are shown, by way of example, on a molded clam shellblister pack container 10, comprising upper 12 and lower 20 surfaces which are preformed and heat sealed together. The container includes the shell orblister portion 18 where the upper and lower surfaces are spaced apart, and thus not sealed together. It is in the shell orblister portion 18 in which the contents of the container are located. - When the user wants to open the container, a cutting means pierces the surface; of the
first surface 12, orsecond surface 20, in the region of thechannel 26 and is drawn through the channel, by way of example, in the direction of the arrows shown inFIGS. 1 and 2 . During this movement the cutting means is drawn through thesurface channel 26. InFIG. 1 , this path follows the edge ofrecess 16 in which an object is stored, while inFIG. 2 the path follows the periphery of thecontainer 10. - It will be appreciated by those skilled in the art that the path formed by channel can be of any shape and does not need to follow the outer edge of the blister portion. Indeed it is possible that only a section of the blister and/or the upper surface needs to be removed to open the container. Often this type of opening is used if the container is intended for re-use. Furthermore is will be appreciated that the container can include means, such as clips, studs and/or the like to re-seal the container.
- The cutting implement could be a small kitchen knife, scissors or specifically designed widget that pierces
channel 26 and is guided along the channel to cut open thecontainer 10. Either thefirst surface 12 or thesecond surface 20 can be pierced and/or cut. Either surface can have a weakened portion in the region of the channel to aid piercing and/or cutting along the channel. By way of example, theedge 14 can run closer to the edge of the packaging, whilst a wall of thechannel 26 can be formed of thinner plastic making the container easier to cut. Cutting action would be straight cuts along thechannel 26 and around the packaging. - Although
FIG. 2 shows achannel 26 around the entire periphery of the container, said channel may only be configured along three (3) edges in order to retain the material of the perforated surface. In this way, the packaging is still in one piece making disposal and re-recycling easier. Sharp edges, perforation burs or shards of plastic are inhibited. - The
channel 26 can be configured abutted close, at a distance of approximately 3 mm, from a welded edge of the container. This facilitates extracting the contacts. -
Multiple steps 14 andchannels 26 can be configured upon a container such that multi-content packaging can be provided e.g. light bulbs. To be clear, in any event both the abutted and the 3-sided guide groove can be used in combination to optimise the opening solution for any particular packaging topology. -
FIGS. 3a and 3b show examples ofchannels 26 that can be formed on acontainer 10. InFIG. 3a thechannel 26 has rounded corners to enable a cutting implement to pass through the channel and open theblister portion 18 in fewer movements or operations. - In
FIG. 3b , the formation has three straight portions with two 90-degree bends along its length. At the corners, overhangs can be provided to make the cutting of the formation easier. -
FIG. 4 shows in cross-section one example of aformation 14 formed in an upperplastic surface 12 that can be positioned above asurface 20. The formation is substantially M-shaped having twopeaks 28 with a trough or groove 16 therebetween. Thesurface 20 can optionally have a recess 22 (not shown) located underneath thegroove 16. The groove can optionally have a thin-walled portion and/or perforations. - In use, the container can be opened by pushing an implement into the groove to penetrate the material at the base of the
grove 16. The implement is then partially constrained by the adjacent walls ofmaterial 12 forming thepeaks 28. If arecess 22 were located beneath the groove the tip of the implement would rest therein. - Once inserted, the implement can be drawn along the groove 16 (in to or out of the page as viewed) and be guided by the
peaks 28. To be clear, the tip of the implement is guided within the void orchannel 26, formed by an air gap, as it moves along thegroove 16 such that it is inhibited from moving out of the groove. - The present invention has been described above purely by way of example, and modifications can be made within the spirit and scope of the invention, which extends to equivalents of the features described and combinations of one or more features described herein. The invention also consists in any individual features described or implicit herein.
