Definitions
- This invention relates to plastic packages and, more particularly, to plastic display packages having a sleeve formed from a die-cut plastic sheet, and a thermoformed product carrier tray that is insertable into sliding and interlocking engagement with the sleeve.
- clamshell display packages have become widely used in the retail marketing of consumer goods. So-called “big box” retailers favor use of the packages because they facilitate display in tray-packs or case-packs and significantly reduce shrinkage attributable to shoplifting, pilfering and employee theft.
- Conventional clamshell packages are typically thermoformed from transparent PVC resin and have two halves that are hinged and can be folded together and sealed after inserting one or more products into recesses formed in one or both sides of the clamshell. Display cards with appropriate graphics or instructions are typically inserted into the packages before they are sealed. Because the PVC is tough and durable, and because the edge closures are typically bonded together by an RF seal, clamshell packages are extremely difficult to open without destroying the package.
- Disadvantages of the conventional clamshell packages to manufacturers include the facts that they are expensive to make, are relatively heavy, are not recyclable, and making the RF seal needed to produce the “destruction bond” consumes time and energy. Consumers, particularly children and senior citizens, are frustrated by conventional clamshell packages because they are extremely difficult, if not impossible, to open following purchase, invite injury from accidental use of sharp or pointed tools needed to access the products, present a disposal problem in that they are neither easily handled nor recyclable. Because clamshell packages typically have irregular thicknesses and tend to have relatively sharp edges, they are also difficult to gift-wrap when the subject products are purchased as gifts.
- plastic packages for displaying products comprise a plastic sleeve having at least one open end into which a product carrier tray, also made of plastic, can be inserted into sliding and interlocking engagement with the sleeve.
- the sleeve is preferably formed by folding and joining opposed side portions of a single rigid plastic sheet to create a continuous side wall having sufficient length and cross-sectional area to receive the product carrier tray into sliding engagement therewith.
- the product carrier tray is preferably thermoformed (sometimes referred to as vacuum-formed) from another rigid plastic sheet made of the same or a different rigid plastic material.
- the plastic sheets used to make the sleeve and product carrier tray, respectively, each preferably further comprise one or more structural elements, as described in greater detail below, that cooperate to provide a mechanical interlock when the product carrier tray is fully inserted into the sleeve.
- the terms “rigid plastic” or “rigid sheet” refers to plastic sheet material, typically cut from rolls formed from extruded webs of thermoplastic resin, that can be die-cut, scored, folded, thermoformed, and taped or glued, for example, to make packaging components such as the sleeve and product carrier tray identified above.
- the sleeves and product carrier trays disclosed herein are understood to be flexible when subjected to manually applied pressure.
- plastics or “rigid sheets” are to be distinguished and differentiated, however, from web rolls of flexible, thin-film plastics such as those commonly used to make products like stretch wrap, shrink wrap or over-wrap, even when made from the same polymeric resins as the “rigid sheets,” and also from injection molded plastic packages such as CD and DVD cases.
- Plastic resins that can be used in making the packages of the invention include, for example, polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), polyvinyl chloride (PVC), polylactic acid (PLA), polypropylene (PP), polystyrene (PS) and high density polyethylene (HDPE), all of which are well known to those of skill in the art.
- PET polyethylene terephthalate
- APET amorphous polyethylene terephthalate
- PVC polyvinyl chloride
- PLA polylactic acid
- PP polypropylene
- PS polystyrene
- HDPE high density polyethylene
- the product carrier tray further comprises at least one end portion adapted to close each open end of the sleeve when the product carrier tray is fully inserted into interlocking engagement with the sleeve.
- the product carrier tray can also be made with at least one hinge member that enables a portion of the tray to be folded back against itself prior to insertion into the sleeve to form the package of the invention.
- Preferred structures for use as mechanical interlocks between the sleeves and product carrier trays in the packages of the invention include, for example,

Abstract
Description
- 1. Field of the Invention
- This invention relates to plastic packages and, more particularly, to plastic display packages having a sleeve formed from a die-cut plastic sheet, and a thermoformed product carrier tray that is insertable into sliding and interlocking engagement with the sleeve.
- 2. Description of Related Art
- In recent years, tamper-resistant clamshell display packages have become widely used in the retail marketing of consumer goods. So-called “big box” retailers favor use of the packages because they facilitate display in tray-packs or case-packs and significantly reduce shrinkage attributable to shoplifting, pilfering and employee theft. Conventional clamshell packages are typically thermoformed from transparent PVC resin and have two halves that are hinged and can be folded together and sealed after inserting one or more products into recesses formed in one or both sides of the clamshell. Display cards with appropriate graphics or instructions are typically inserted into the packages before they are sealed. Because the PVC is tough and durable, and because the edge closures are typically bonded together by an RF seal, clamshell packages are extremely difficult to open without destroying the package.
- Disadvantages of the conventional clamshell packages to manufacturers include the facts that they are expensive to make, are relatively heavy, are not recyclable, and making the RF seal needed to produce the “destruction bond” consumes time and energy. Consumers, particularly children and senior citizens, are frustrated by conventional clamshell packages because they are extremely difficult, if not impossible, to open following purchase, invite injury from accidental use of sharp or pointed tools needed to access the products, present a disposal problem in that they are neither easily handled nor recyclable. Because clamshell packages typically have irregular thicknesses and tend to have relatively sharp edges, they are also difficult to gift-wrap when the subject products are purchased as gifts.
- More recently, applicant has disclosed in a co-pending application fully recyclable, tamper-resistant packaging in which a product is displayed inside a full-thickness recess in a folded inner box that is insertable into a substantially transparent, plastic outer box, which outer box is then sealed with a destruction bond seal. The use of a transparent, thermoformed tray to support the product within a recess in the inner box is also disclosed.
- Notwithstanding the advantages and benefits achievable through use of such prior art packages, however, there remains a need for rigid, tamper-resistant packages that can be easily and inexpensively fabricated from die-cut plastic sheet material in which products can be attractively and visibly displayed, and that are resistant to theft or pilfering of the contained products without the need for a destruction bond seal.
- According to a preferred embodiment of the invention, plastic packages for displaying products are disclosed that comprise a plastic sleeve having at least one open end into which a product carrier tray, also made of plastic, can be inserted into sliding and interlocking engagement with the sleeve. The sleeve is preferably formed by folding and joining opposed side portions of a single rigid plastic sheet to create a continuous side wall having sufficient length and cross-sectional area to receive the product carrier tray into sliding engagement therewith. The product carrier tray is preferably thermoformed (sometimes referred to as vacuum-formed) from another rigid plastic sheet made of the same or a different rigid plastic material. The plastic sheets used to make the sleeve and product carrier tray, respectively, each preferably further comprise one or more structural elements, as described in greater detail below, that cooperate to provide a mechanical interlock when the product carrier tray is fully inserted into the sleeve.
- As used herein, the terms “rigid plastic” or “rigid sheet” refers to plastic sheet material, typically cut from rolls formed from extruded webs of thermoplastic resin, that can be die-cut, scored, folded, thermoformed, and taped or glued, for example, to make packaging components such as the sleeve and product carrier tray identified above. Although said to be “rigid,” the sleeves and product carrier trays disclosed herein are understood to be flexible when subjected to manually applied pressure. Such “rigid plastics” or “rigid sheets” are to be distinguished and differentiated, however, from web rolls of flexible, thin-film plastics such as those commonly used to make products like stretch wrap, shrink wrap or over-wrap, even when made from the same polymeric resins as the “rigid sheets,” and also from injection molded plastic packages such as CD and DVD cases. Plastic resins that can be used in making the packages of the invention include, for example, polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), polyvinyl chloride (PVC), polylactic acid (PLA), polypropylene (PP), polystyrene (PS) and high density polyethylene (HDPE), all of which are well known to those of skill in the art.
- According to a particularly preferred embodiment of the invention, the product carrier tray further comprises at least one end portion adapted to close each open end of the sleeve when the product carrier tray is fully inserted into interlocking engagement with the sleeve. The product carrier tray can also be made with at least one hinge member that enables a portion of the tray to be folded back against itself prior to insertion into the sleeve to form the package of the invention. Preferred structures for use as mechanical interlocks between the sleeves and product carrier trays in the packages of the invention include, for example,
