In the case of the pair of secondary end seals 321c/321d, the notch R makes it easy to divide into two separate sections. In addition, the terminal end 373 of the recess may be changed to a pointed shape or a curved shape. Alternatively, it is optional to provide an access structure only at one end of the carton 330. In addition, other embodiments contemplate that only the access structure is provided at the other end of the carton 330, or that the access structure is provided at both ends of the carton 330.

Turning now to the description of the manufacture of the carton 330, the carton 330 is conceived to be capable of performing a series of sequential bending operations on a linear machine and forming it so that the carton can be completed without turning or flipping. . The bending process is not limited to those described later, and may be modified in accordance with specific manufacturing requirements.

The semi-formed flat flap 310 (formed after the glued backsheet 320 is adhered to the second side panel 312) can be flared into an open tubular sleeve. The carton 330 includes two composite end wall panels, each of which is formed by first connecting the secondary end sealing pieces 321c/321d, 321a/321b, 326b, 322b around the main plate pieces 316, 312. The portions 340/325c, 338, 325a; 327c, 327a are bent. Then, the main end sealing pieces 323b and 324b connected to the main plate piece 314 can be selectively bent around the connecting portions 325b and 327b of the bottom plate piece 314 to be respectively connected with the sub-end end seals. The crotch panels 321c/321d, 321a/321b, 326b, 322b constitute an at least semi-overlapping configuration. Preferably, at least the tear strip 332 disposed on the secondary end sealing piece 321a/321b is adhered to the bottom portion of the bottom end sealing piece 323a/376, and the secondary end sealing piece 321a is preferably It is also implemented as such. To accomplish this, an adhesive may be applied to one or both of the secondary end seal 321a and the associated portion of the bottom end seal 323a/376.

Alternatively, the adhesive may be applied to the main end seals 328a, 328b and/or the bent main end seals 323b, 324b and/or the secondary end seals 321c/ 321d, 321a/321b, 326b, 322b. Then, the unbent main end sealing piece 328a, 328b is bent and adhered around the connection portion of the top end piece 318 to the lower portion thereof The main end sealing sheets 323b, 324b and/or the sub end sealing sheets 321c/321d, 321a/321b, 326b, 322b. Preferably, the top end sealing piece 328a constituting a part of the taking structure is adhered to the upper portions 321d, 321a of the secondary end sealing pieces 321c/321d, 321a/321b, and the bottom end sealing piece The upper portion 323a of the outer surface of 323b. In this manner, the frangible sections 328a, 321, 323a, 376, 321a, 332 are joined or adhered together and thus substantially as a single piece or component 328a/321d/323a/321a (e.g. It is removed as described later, and the tear strip 376/332 is removed as another separable material.

2 is an external view of the composite endwall 328a/323b/321d/321c/321a/321b of the access structure 328a/321d/323a/321a/332/376.

The access structure shown in Figure 2 is in an unused state in which the carton structure 330 remains intact and the item A cannot be accessed. As shown, the frangible line 352 is fully engaged with the hinge portion 325d (i.e., as shown in Figure 1) between the top panel 318 and the top end sealing tab 328a. The top end sealing tab 328a provides a first frangible section of the access structure, the section being removable as the access structure is disassembled, thereby providing a depth of at least about half of the carton and Corresponds to the full width of the carton (see Figures 4 and 5). Preferably, the top end sealing piece 328a is adhered to (optionally a hot melt adhesive, but other suitable adhesive means may also be used) an upper portion 323a of the bottom end sealing piece 323b; the first side An upper portion 321d of the end sealing jaw 321c/321d; and an upper portion 321a of the second side end sealing tab 321a/321b (as described above). In addition, the side edge of the top end sealing piece 328a may be tapered, and the other parts of the body of the carton 330 are not in use except for the frangible hinge 352 of the top plate 318. Some parts of the structure are connected. The top end sealing tab 328a can be used to join the frangible sections 321d, 323a, 321a of the access structure to each other.

The additional breakable lines 340, 334 are disposed on the secondary end sealing piece 321c / 321d, and are configured to separate the secondary end sealing piece 321c / 321d into two sections: with the access The structure removed 321d; and (with the hinge portion 325c with the first side panel 316) is always attached to the cardboard box 330 321c.

The frangible lines 374a, 374b disposed on the primary end sealing tab 323b form a perforated tear strip 376. An unsealing section can be provided at one end of the tear strip 376 to assist the user in grasping the tear strip 376. A lower secondary end sealing piece 321a may alternatively be further comprised of a crack Or the perforation lines 374c, 374d together with an unsealing section 378 define a portion of the tear strip 332. Another frangible line 338 disposed on the secondary end sealing piece 321a/321b is configured to separate the secondary end sealing piece 321a/321b into two sections: 321a removed with the access structure And (with the hinge portion 325a with the second side panel 312) always attached to the cardboard box 330 321b.

The unsealing section 378 is configured to initiate disassembly of the separable access structure. The unsealing section 378 can optionally include an aperture disposed in the secondary end sealing tab 321a/321b. However, in other embodiments, the unsealing section 378 is also contemplated as being mountable on the bottom main end sealing tab 323a/323b. Alternatively, the unsealing section 378 can include a push tab that is at least partially defined by a frangible line, a weakened line, or a fold line. Such a pressing piece may be provided with a weakened area which is easier to be disconnected from (or disconnected from) the other end sealing piece 321a/321b. Accordingly, the user can utilize the aperture of the unsealing section 378 to fully grasp the composite tear strip 376/332 to pull the composite tear strip along the frangible lines 374a, 374b, 374c, 374d. 376/332 and tear it apart (see Figure 3).

The remainder of the separable access structure can be separated from the carton 330 after the tear strip 376/332 is disassembled or during disassembly. After the tear strip 376/332 is disassembled or during the disassembly, the frangible line 334 can be broken to such an extent that the secondary webs 321a/321b, 321c/321d are separated into two portions. Thus, the user can pull up the remaining frangible sections to break the joints 340 that meet the hinges adjacent the first and second side wall panels 316, 312 (see FIG. 3), 338. Then, the frangible connection portion 352 which meets the apex or corner between the top end sealing piece 328a and the top plate piece 318 is torn along the forming position, so that the detachable structure can be taken from the carton The remainder of 330 is completely separated. In this regard, none of the top sheet 318, the first side panel 316, or the second side panel 312 will, or at least not have, a substantial portion be removed from the carton 330. Only a portion of the composite end panel structure will be removed. Therefore, the structure of the body of the carton 330 remains intact and can be used to hold and hold the articles A loaded therein. The remaining portion 323b/321c/321b of the composite end panel forms a stop panel that is high enough to prevent any items from inadvertently falling out, yet low enough for the consumer to easily remove the item through the opening provided.

Therefore, after the take-up structure is removed, the carton body has the benefit that the structure remains intact. This is stored in a humid environment such as a refrigerator in the carton 330 (moisture can let paper The plate substrate is weakened, and/or the carton 330 is useful when loaded with heavy objects (eg, 12 oz/330 ml glass bottles). In addition, the consumer is also willing to use the design of the present invention to place the carton 330 into the refrigerator, as it is more difficult to access the article through the top of the carton due to the height restriction of the refrigerating compartment and the shelf height. Therefore, as long as an opening (optionally provided at the end of the smallest width instead of the wider side) is provided on the end wall, it is placed when the carton 330 is placed in the shelf of the refrigerator. In the front, the need to remove items from the top plate of the carton can be alleviated, and the need to reduce the height of the refrigerator is higher than that of the carton 330. If the items are tapered, such as bottle A, and for reasons of stability and for the protection of fragile items (bottles such as glass), it is necessary to consider the items and the bottom, top and end walls of the carton. The relative orientation of the panels, at which point the carton 330 is oriented such that the bottom panel 314 that is in contact with the bottom of the articles A is always at the bottom.

It will be appreciated that variations can be made without departing from the scope of the invention, for example, the size and shape of the plates and apertures can be adjusted to match different types, sizes, numbers, configurations and/or shapes. article. In other embodiments of the invention, it is contemplated that a frangible access opening may be added to the top panel 318 to provide another user when the user chooses not to store the carton in the refrigerator. Alternative access points.

It will also be understood that the various directional terms used in this article, such as "top", "bottom", "before", "after", "end", "side", "inside", "outside", "upper" And "below", etc., does not limit the relevant sheets to the orientation, but only to distinguish the sheets.

As used herein, "hinged portion" and "folding line" refer to a hinge member that defines the web and that facilitates the bending of portions of the sheet relative to each other or indicates the proper curvature of the sheet to which the sheet belongs. A wide variety of lines in the folded position. Typically, the fold line is a score line, an embossed line, or a debossed line. Any reference to a hinge or fold line is not to be construed as necessarily limited to a single fold line; in fact, the hinge may be constructed of one or more of the following without departing from the scope of the invention: short seam (short slit), frangible line, or fold line.

As used herein, "cut line" refers to a wide variety of lines that cause portions of the substrate to be easily separated from each other or to indicate a suitable separation. The cutting line can be a cracked or otherwise weakened line, a tear line, a cut line, or a crack.

It should also be understood that the hinge, the cutting line and the folding line may each comprise an element formed on the blank substrate, such as a perforation, a perforation line, a short suture, a half-cut line, a single half. Cuts, cut lines, interrupted cut lines, cracks, scores, any combination thereof, and the like. These components may be sized and configured according to the intended function. For example, the perforation lines can be sized and designed to have a degree of weakness that can define fold lines and/or cut lines. In addition, the perforation line can be designed to be easily bent and resistant to breakage, to be easily bent and to be easily broken by using a little force, or to be easily broken with a little force.
