DISPLAY CARTON
The carton is comprised of an attached arrangement an outer front panel, a top panel, a rear panel, a bottom panel and an inner front panel; the outer front panel overlaying the inner front panel and having an attachment strip at a lower edge for attachment to the inner front panel. The attachment strip has an outer front panel weakened area whereby upon the outer front panel being separated from the inner front panel this weakened area is severed leaving the attachment strip attached to the inner front panel. The outer front panel will have a grip tab to open the carton by severing the outer front panel weakened area of the attachment strip, with the attachment strip remaining with the carton.

This application is a continuation of U.S. patent application Ser. No. 12/161,805, filed Jul. 23, 2008, which in turn is a National Stage Entry of International Application No. PCT/US2006/002738, filed Jan. 25, 2006. The disclosures of the above applications are incorporated herein by reference in their entireties.
FIELD OF THE INVENTIONThe present invention relates to a display carton with a tamper evident structure which upon opening the carton the contained product is clearly displayed. The present invention also relates to a carton blank for the production of the carton.
BACKGROUND OF THE INVENTIONThere is a constant need for cartons for the tamper evident packaging of products and for the full display of the products upon the carton being opened. The carton should have a tamper evident structure where all of the tamper evident structure remains with the carton and which has a grip means for the easy opening of the carton. Cartons in the prior art are of the display type and they also have tamper evident structures. U.S. Pat. No. 3,378,188 discloses a display carton with a removable tamper evident tear strip. The tamper evident tear strip is gripped and removed from the carton and the carton then is opened. The removed tamper evident tear strip then is discarded. Similar structures are disclosed in U.S. Pat. No. 3,206,102; U.S. Pat. No. 3,368,738 and U.S. Pat. No. 3,379,361. Each discloses a carton with one or more removable tear strips which then allows the carton to be opened. However this results in a debris tear strip that has to be discarded. Additionally, these tear strip can be difficult to grip to open the carton.
The present invention is directed to a display carton that easily opens by lifting an outer front panel and in turn a top panel to clearly show the product in the carton. The carton has an outer front panel which has an attachment strip that functions to seal the carton closed and to provide for tamper evidence. The outer front panel also has a grip tab adjacent to the attachment strip to assist in the easy opening of the carton by the severing of the weakened area between the attachment strip and the remainder of the outer front wall. No part of the carton is removed so there is no material to be discarded, such as a tear strip. It solves the problem of easy opening and no package parts to be discarded after opening.
BRIEF SUMMARY OF THE INVENTIONThe invention comprises a carton having in an attached arrangement an outer front panel, a top panel, a rear panel, a bottom panel and an inner front panel, the outer front panel overlaying the inner front panel and having an attachment strip on a lower edge thereof for attachment to the inner front panel. The attachment strip has an outer front panel weakened area whereby upon the outer front panel being separated from the inner front panel this weakened area is severed leaving the attachment strip attached to the inner front panel. The remainder of the outer front panel is not attached to the inner front panel. The inner front panel, bottom panel, rear panel, and optionally the top panel, have a side flap on each longitudinal end thereof, with the outer front panel being devoid of side flaps. The top panel can be devoid of side flaps, but if it does have side flaps there preferably will be a weakened area between the top panel and each side flap to facilitate the opening of the carton.
The carton has a grip tab adjacent to, but separated from, the outer front panel weakened area of the attachment strip on the outer front panel. As noted above there also can be weakened areas between the top panel and the appended top panel flaps when the top panel has flaps. The side flaps are folded, one onto the other, to form the end panels of the carton.
The carton blank is in an attached arrangement of an outer front panel, a top panel, a rear panel, a bottom panel and an inner front panel. The outer front panel has an attachment strip at a lower edge thereof for attachment to the inner front panel in forming the carton. The attachment strip has a weakened area whereby upon the outer front panel being separated from the inner front panel the weakened area is severed leaving the attachment strip attached to the inner front panel. There is a grip tab on the outer front panel to assist in gripping the outer front panel and severing the weakened area near the attachment strip. Each of the panels has an appended flap on each longitudinal end except for the outer front panel and optionally the top panel.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The carton now will be described in its preferred embodiments with reference to the drawings. It is to be understood that the described embodiments can be modified but yet be within the described concept and be within the scope of the invention.
The carton blank of
The carton blanks in one sequence can be formed into the cartons by folding front inner panel 12 upward with respect to bottom panel 14 at the score line. Rear panel 16 can then be folded upward from bottom panel 14 at the score line and top panel 18 folded over from rear panel 16 at the score line. Outer front panel 20 is then folded down over inner front panel 12 at the score line. The weakened areas 23, 15(a) and 15(b) usually are formed in the blanks at time of forming the blanks by cutting the blanks from a larger sheet of material. The carton blanks also can be formed into the cartons by other folding sequences. After the folding sequence the carton can be filled from one of the ends and the flaps folded over at the score lines and sealed. The flaps will have adhesive strips or spots that can be activated to seal the cartons. As an option the flaps on one end of the carton can be folded over at the score lines and sealed, the product inserted, and the flaps on the other end folded then over at the score lines and sealed. Not all of the flaps need to have an adhesive. If all of the flaps have adhesive essentially any folding sequence can be used prior to sealing. However, if only flaps 16(a)/16(b) and 12(a)/12(b) have adhesive flaps 14(a)/14(b) and 18(a)/18(b) will be folded over first and then flaps 16(a)/16(b) and 12(a)/12(b) so that flaps 16(a)/16(b) and 12(a)/12(b) will be in contact and to be adhesively attached to the other. It is preferred to use hot melt adhesives that are commonly used to seal cartons. However, pressure sensitive and other adhesives can be used.
Essentially any product can be packaged in this carton. One advantage is that the purchaser will be able to fully see the product upon opening the carton. Further it provides additional space for text information. As noted this can be precautionary information with regard to the product or product promotional information. It has been found to useful for packaging over the counter pharmaceuticals and dentifrices.
The cartons can be made out of a paperboard that is conventionally used to make cartons. This can be a paperboard or a paperboard laminate with one or more plastic layers. The carton also can be a fully plastic carton. However, it is preferred that it be a paper board or a paperboard/plastic laminate carton material. The panels are separated one from the other by score lines with the carton material folding at the score lines. There also are score lines between the panels and their appended flaps. The score lines promote the folding at those areas. The score lines are of a conventional type and are formed using conventional techniques.
