Definitions

  • the present invention relates generally to cartons. More specifically, the invention relates to an interlocking food carton which may be compactly stored and easily assembled. Description of the Related Art
  • the present invention is directed to an interlocking carton which is easily assembled.
  • the container or carton includes an inner receptacle and an outer removable sleeve.
  • the inner receptacle is a boat-like structure or tray upon which food is placed.
  • the outer removable sleeve slidably engages with the inner receptacle to enclose or cover the contents of the inner receptacle.
  • the inner receptacle also includes a locking mechanism, such as a protruding lip, that locks the outer removable sleeve in place after engagement. This locking mechanism enables safe transit of the contained food so that the carton does not automatically disengage.
  • many inner receptacles may be stacked inside one another for compact storage.
  • the outer sleeves may be stored in a flat position.
  • a user holds the inner receptacle with one hand while simultaneously lifting the outer sleeve with the other hand and slidably engaging the sleeve over the tray until the locking mechanism engages (e.g., the lip of the receptacle protrudes over the sleeve), thereby locking the two pieces together.
  • the act of lifting the outer sleeve as well as squeezing the sides of the outer sleeve together facilitate converting the outer sleeve from its stored flat position to a constructed position.
  • FIGURE 1 is a perspective view of one embodiment of an interlocking carton showing an outer removable sleeve and an inner receptacle fully engaged;
  • FIGURE 2 is a right side view of one embodiment of an interlocking carton showing the outer removable sleeve and the inner receptacle fully engaged;
  • FIGURE 3 is a front perspective view of one embodiment of an interlocking carton showing the outer removable sleeve and the inner receptacle fully engaged
  • FIGURE 4 is a bottom plan view of one embodiment of an interlocking carton showing the outer removable sleeve and the inner receptacle fully engaged;
  • FIGURE 5 is a perspective view of one embodiment of the inner receptacle of the carton shown in FIGURE 1;
  • FIGURE 6 is a top view of the inner receptacle as a single piece of material
  • FIGURE 7 is a perspective view of one embodiment of the outer sleeve of the carton shown in
  • FIGURE 1
  • FIGURE 8 is a top view of the outer receptacle as a single piece of material
  • FIGURE 9 is a top plan view of one embodiment of the outer sleeve shown in a collapsed form
  • FIGURE 10 is a perspective view of an additional embodiment of an interlocking carton showing an outer removable sleeve and an inner receptacle fully engaged
  • FIGURE 11 is a perspective view of one embodiment of the inner receptacle of the carton as shown in FIGURE 10;
  • FIGURE 12 is a perspective view of one embodiment of the outer sleeve of the carton shown in FIGURE 10; and FIGURE 13 is a perspective view of an additional embodiment of an interlocking carton showing an outer removable sleeve and an inner receptacle fully engaged.
  • the present invention provides an interlocking carton comprised of an inner receptacle and an outer sleeve that may be efficiently stored and readily assembled for use. Further, the carton may be engaged by sliding the inner receptacle into the outer sleeve and engaging a locking mechanism. To "unlock” the carton, the inner receptacle may be removed from the sleeve by disengaging the locking mechanism.
  • FIGURE 1 illustrates one embodiment of an assembled and interlocked carton 110 that includes an inner receptacle 120 and an outer sleeve 130.
  • the exemplary carton 110 includes a protruding lip 122 on the inner receptacle 120 that extends above the outer sleeve 130 thereby serving as a locking mechanism. Once the inner receptacle 120 has been fully inserted into the outer sleeve 130, the protruding lip 122 extends above the top of the outer sleeve 130 making it difficult to unintentionally disengage the carton 110.
  • FIGURE 2 illustrates a right side view of the assembled and interlocked carton 110.
  • the protruding lip 122 extends past the top edge of the outer sleeve 130, thereby locking the inner receptacle 120 and the outer sleeve 130 together.
  • the inner receptacle 120 does not continue to slide forward in relation to the outer sleeve 130 due to the width of the inner receptacle 120. It is recognized that in other embodiments other methods may be used to prevent the inner receptacle 120 from sliding forward in relation to the other sleeve 130, such as, for example, the use of locking mechanisms.
  • the inner receptacle 120 is prevented from inadvertently sliding back through the outer sleeve 130.
  • FIGURE 3 illustrates a front view of the assembled and interlocked carton 110, wherein the protruding lip 122 extends from the front of the inner receptacle 120 locking the removable outer sleeve 130 into place so that the outer sleeve covers the contents of the inner receptacle 120.
  • This locking mechanism may be used to securely hold the outer sleeve 130 and the inner receptacle 120 together to store items, such as food, within the carton 110.
  • FIGURE 4 illustrates a bottom view of the assembled and interlocked carton 110, wherein the outer sleeve 130 and the inner receptacle 120 are fully engaged.
  • FIGURE 5 illustrates the inner receptacle 120 of the carton shown in FIGURE 1.
  • the inner receptacle 120 includes a bottom or base portion 510, a back wall 520, a left side wall 530, a right side wall

It is recognized that a variety of adhesive materials, such as glue, may be used to secure the walls 520, 530, 540, 550.
  • the inner receptacles 120 may be formed, secured, stacked, and efficiently stored taking up little space. In one embodiment, the stacked inner receptacles 120 may then be shipped to various restaurants.
  • the carton 110 is shaped to receive a food article.
  • the exemplary carton 110 has a triangular or wedge shape that may be suitable for holding a slice of pizza or pie. While the exemplary carton 110 is described herein as a container for a pizza slice, it is recognized that the triangular shaped carton 110 may be used as a container for a variety of food or non-food items and is not limited to pizza. Furthermore, it is recognized that the carton 110 may be formed in a variety of shapes such as trapezoids, rectangles, squares, and so forth.

Abstract

L'invention se rapporte à un récipient pour aliments comportant un réceptacle interne et un manchon externe. Le réceptacle interne et le manchon externe sont emboîtés coulissants pour permettre au récipient de contenir un aliment. Le récipient possède un mécanisme de blocage qui met le réceptacle interne en prise avec le manchon externe de façon à empêcher toute ouverture accidentelle du récipient. Le manchon externe se plie à plat, de sorte qu'il peut être conservé dans un espace restreint.
