Definitions
- the present invention is directed to a semi-rigid packaging unit for articles such as razors, articles of personal use and the like.
- Blister packs are known to have a plastic blister front and a cardboard rear wall, the plastic front being glued to the cardboard, which is opened when the user peels the two halves away from one another or pulls back a perforated flap or panel on the cardboard back wall. Examples of these packs are shown in U.S. Pat. No. 4,095,691 issued to Iten; U.S. Pat No. 3,972,417 issued to Iten et al.; U.S. Pat. No. 3,970,194 issued to Iten; and U.S. Pat. No. 3,933,245 issued to Mullen.
- the present invention comprises a packaging unit.
- the packaging unit comprises a front wall and a back wall sealed together at a peripheral joint.
- the front wall and the back wall are formed of semi-rigid material and are spaced apart from one another to define an article-receiving region between them.
- a line of weakness is formed in the back wall.
- the line of weakness defines an opening flap to be at least partially separated from the remainder of the back wall.
- a raised opening tab is positioned on the opening flap along the line of weakness. The raised opening tab extends away from the opening flap.
- the line of weakness is rupturable by a user by applying a manual force to the opening tab to at least partially separate the opening flap from the remainder of the back wall along the line of weakness in order to access the article -receiving region.
- the front and back walls may be formed of plastic or cardboard.
- the line of weakness comprises perforations.
- the peripheral joint may comprises a heat-sealed seam, a radio frequency sealed seam a ultrasonic sealed seam or an adhesively sealed seam.
- the packaging unit may further comprise a hinge in the back wall to facilitate separation of the opening flap from the back wall.
- the opening flap may be completely separable from said back wall.
- FIG. 1 is a front view of a packaging unit of the present invention.
- FIG. 2 is a front isometric view of the packaging unit of FIG. 1.
- FIG. 3 is a rear view of the packaging unit of FIG. 1.
- FIG. 4 is a bottom view of the packaging unit of FIG. 1.
- FIG. 5 is a rear isometric view of the packaging unit of FIG. 1 with the opening flap partially separated from the back wall.
- FIG. 6 is a rear view of another packaging unit of the present invention.
- the packaging unit 10 is comprised of two spaced-apart walls, front wall 11 and back wall 12 that have been formed to define an article-receiving region 13 between them commonly referred to as a blister, pouch, pocket or cavity.
- the walls can be referred to as a sheet, foil or panel.
- the article-receiving pouch shape can be formed into one wall and the other be flat, but it is preferred that both front wall 11 and back wall 12 define parts of the article-receiving pouch.
- the packaging unit 10 may have a plurality of shapes, including rectangular, circular or oval; preferably, in general, having a rectangular shape.
- the front wall 11 and back wall 12 are formed of semi-rigid material, which generally retains a shape, e.g. the blister shape, into which it is formed, and is relatively stiff.
- the front wall 11 and back wall 12 are formed of plastic material, preferably transparent plastic, to permit viewing of the article contained therein prior to purchase.
- plastic material preferably transparent plastic, to permit viewing of the article contained therein prior to purchase.
- other non-transparent materials may be used.
- the semi-rigid plastic material walls 11, 12 can be thermally formed from plastic materials, preferably polyester materials. Suitable materials also include, without limitation, PVC, PET G (extra glycol polyester), PET, PETGAG and PP.
- suitable forming techniques include vacuum forming and deep drawing, whereby a sheet of material is drawn down with the assistance of pressure over an aluminum tool corresponding in shape to the article-receiving region 13 to be formed, then cooled and set.
- one wall could be made of plastic and another wall of cardboard or paperboard.
- the use of an all-plastic packaging unit has the advantage that it may be recyclable without having to separate dissimilar materials, is strong and provides a good opportunity to view the contained article. It is understood that the materials can be chosen with regard to the weight of the article to be packed therein, the desired resistance to package crushing or deformation, material cost, and environmental matters such as ease of recycling a package made of a homogenous material rather than dissimilar materials.
- the packaging unit 10 is sealed along a peripheral joint 14.
- the packaging unit 10 is preferably sealed around all peripheral edges.
- the sealed packaging unit 10 defines a semi-rigid assembly which has a good degree of stiffness to protect an article contained therein and resists accidental opening.
- the peripheral joint 14 may be achieved by use of such convenient techniques as adhesives, ultrasonic, heat-sealing, radio-frequency (RF) sealing (also referred to as "high frequency” HF sealing), or firm mechanical interlock. It is preferred that the joint be strong enough such that it is not easily peeled apart (i.e., resists delamination), since it is not necessary for the consumer to separate the layers of the joint itself.
- the type of joint chosen depends on the material of which walls 11, 12 are made, as is understood in the art.
- a heat seal or RF seal is understood in the art to form a firm, "welded” joint in the classes of preferred plastics such as above mentioned, as is commonly used in blister packs and well understood in the art.
- a suitable RF seal is about 2.5 mm wide in plan view.
- Adhesives of the isocyanate type would also "weld" these kinds of plastics, although rubber based adhesives are not preferred since they are less resistant to being peeled open. Also alternatively, if one wall were made of plastic and the other of cardboard, a suitable adhesive can form the joint, as is well understood in the art.
- a line of weakness or weakened region 15 formed in back wall 12.
- the line of weakness 15 is approximately parallel and coextensive with portions of the peripheral joint 14, and formed by perforations 16.
- the line of weakness 15 defines an opening flap 20.
- a raised opening tab 24 is positioned on the opening flap 20 along the line of weakness 15. The raised opening tab 24 extends away from the opening flap 20. By extending away from the opening flap 20, the raised tab 24 provides a convenient location for a user to grasp when opening the packaging unit 10.
- Perforations 16 can be any convenient weakening and/or stress-concentrating features such as made by mechanical die cutting or slitting.
- the perforations 16 can be formed to extend through back wall 12 as might conveniently be done with die cutting or slitting. Depending on the material, as understood in the art 100 percent cuts (slits extending through 100% of the thickness) could be sufficient. Perforations 16 are formed to completely extend through back wall 12, such as by cutting fully through the material's thickness, as is presently preferred.
- the perforations 16 can be formed subsequent the formation of the plastic material back wall 12. It is preferred that perforations 16 be done in the blank for back wall 12 before the front and back walls 11, 12 are heat-welded together, since then the wall forming step can be done in one operation; otherwise, if the perforations 16 were formed after the walls are heat- welded, that would require an additional processing step.
- the article within packaging unit 10 may be an article of personal use, such as a razor, a razor blade unit, a shaving unit, a shaving head, a toothbrush, a battery, an energy or other fuel cell for an electric or gas powered appliance, or the like.
- Packaging unit 110 is identical to packaging unit 10 of FIGS. 1-5, with one distinction.
- the one distinction is that line of weakness 115 allows opening flap 120 to be completely removed or separated from the remainder of back wall 112.
- the line of weakness 115 defines an opening flap 120.
- a raised opening tab 124 is positioned on the opening flap 120 along the line of weakness 115.
- the raised opening tab 124 extends away from the opening flap 120. By extending away from the opening flap 120, the raised tab 124 provides a convenient location for a user to grasp when opening the packaging unit
- the opening flap 120 can be completely separated from the remainder of the back wall 112 allowing for easy access to the article -receiving region 113.
