Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to wrap-around shipping containers used to carry multiple beverage containers, and in particular to a descent partition from a portion of the inner top panel. A transport container as formed.

Description of the Prior Art A shipping container with a drop down partition formed from the inner top panel of the container is described in U.S. Pat. Nos. 4,043,095 and 4,1.
No. 55,449, it has been in commercial use for many years. However, the transport container having such a structure has the following problems. That is, when forming a descent partition using one of several layers of paperboard, a single paperboard portion remains in the area surrounding the handle. Bursting and breakage are very likely to occur in such areas. Therefore, attempts have been made to solve this problem by using thick paperboard. However, although thick paperboard is expensive and is not needed in most areas other than the handle area, it must be used for the entire shipping container.

FIG. 2 of the present application shows a handle structure of a shipping container that is commercially available before the present invention. In this shipping container, in a region around the opening of the handle, the thickness is two layers or three layers. Designed in layers. However, in other areas around the handle opening, the thickness remains a single layer. If the shipping container is assembled from cardboard of sufficient thickness, there is no functional problem. However, in order to reduce the cost of the package and make it competitive in the market, it is desirable that the paperboard of the container be as light as possible without compromising the function of the container.

It is an object of the present invention to allow a shipping container with a drop down partition of the type described above to be made from lighter paperboard without compromising its functionality. As a matter of fact, when a carrying container having a handle structure as shown in FIG. 2 of the present application is made from paperboard having a thickness of 27 points (1 point is about 0.0254 mm), 24
Can be created from point paperboard.

SUMMARY OF THE INVENTION The present invention achieves the above-identified object by reinforcing the handle structure by making the thickness of the paperboard in the stressed area of concern close to the handle opening at the top of the container at least double. . The handle reinforcing portion is provided close to the handle opening and has a two-layer structure in thickness. In order to make the present invention and its advantages more comprehensible, preferred embodiments are described below with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view showing a material for a carrying container of the present invention, FIG. 2 is a view showing an inside of an adhesively bonded upper panel of a known carrying container, and FIG. FIG. 3 is a view showing the inside of the upper panel that is adhesively bonded to the transport container of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a material 10 according to the present invention.
A container for transportation is made by folding 10 and adhering with an adhesive. Material 10 consists of a bottom panel 14 and side panels 16, 18
An outer upper panel 20, an inner upper panel 22, and end panels 24, 24 ', 26, 26', 28, 28 'and 30, 30'.

The outer upper panel 20 has a pair of elongated handle openings 32 and 34 that are spaced apart from one another, and these handle openings are provided with handle tabs (ears) 36, 38. Handle opening 32 and handle tab 36
Is formed by a die cut 40 and a score line 42. Further, the handle opening 34 and the handle tab 38 are formed by the punched-out portion 44 and the polygonal line 46. Handle tab 36
And 38 are outer upper panels along fold lines 42 and 46, respectively.
It is hinged on 20.

The inner upper panel 22 has a pair of elongated handle openings 48, 50 spaced apart from each other, a descending partition 52, and a handle reinforcing portion 54. The handle opening 48 and the handle tab 56 are formed by a punched-out portion 58 and a polygonal line 60. The handle opening 50 and the reinforcing tab 62 are formed by a punched-out portion 64 and a polygonal line 66.

The descending partition 52 is composed of a main partition part 68 and a pair of connecting strips 70 and 72. The connecting strips 70 and 72 are broken lines 74 and
Hinged to the inner upper panel 22 at 76. The polygonal lines 74 and 76 are located on the extension of the center line that crosses the handle openings 48 and 50. Punched parts 73 and 75
The upper partition 22 and the lowering partition 52 are partitioned from the upper panel 22 together with the punching section 78.

A part of the handle reinforcing portion 54 of the inner upper panel 22 is punched out 58.
And 64 and by means of which the handle opening 48
Adjacent to 50 and 50, the punched portions 58 and 64 also define the inner edges of the partition strips (70, 72). The remaining edge of the handle reinforcing portion 54 is defined by a substantially U-shaped punching portion 78, and this punching portion 78 also defines most of the upper edge of the main partition portion 68. The handle reinforcement 54 extends over the entire width of each handle opening 48 and 50, since its width is equal to the length between the outer edge of the handle opening 48 and the outer edge of the opening 50. On the other hand, as shown in U.S. Patent No. 4,043,095,
The known reinforcement only extends over part of the mouth width of the handle opening.

In making container 12 from blank 10, outer and inner upper panels 20 and 22 are adhesively bonded together as shown in FIG.
As shown in FIG. 3, the outer upper panel 20 overlies the inner upper panel 22, and both panels are completely coextensive. The handle openings 32 and 34 of the outer upper panel 20 are aligned with the handle openings 48 and 50 of the inner upper panel 22 in both the horizontal and vertical directions. The handle tabs 36, 38, 56 are bent inward as shown. Inner top panel
The reinforcing tabs 62 of the 22 are folded back over the inner upper panel 22 and adhesively bonded thereto so that the handle openings 32, 48 and the handle openings are opened.
A three-layered handle is formed between 34 and 50. This reinforcement tab
The width of 62 corresponds to the distance between the inner edges of the handle openings 48 and 50. The ends of the handle openings 48 and 50 coincide with the ends of the handle openings 32 and 34. In this way, the handle opening 3 shown in FIG.
The regions on the left and right of the handlebar openings 48 and 50 and the handlebar openings 34 and 50 have a two-layer structure over the entire width of these handle openings, so that the handles can be prevented from being ruptured or damaged. The reinforcing portion 54 separated from the partition reinforces the left side of the container shown in FIG. 3, and the outer upper panel 20 and the inner upper panel 22 have a double layer structure on the right side. In known transport containers, handle opening
The entire width on the left side of the handles 32, 48 and the handle openings 34, 50 does not have a double-layer paperboard structure. A stiffening tab 62 joined to the inner upper panel 22 (which is joined to the outer upper panel 20) forms a three-layer structure between the handle openings 34, 50 and the handle openings 32, 48.

FIG. 2 shows a known handle structure in which a reinforcing tab 202 is folded back onto an inner upper panel 204 and adhesively fixed thereto. In addition, this inner upper panel 20
4 is adhesively fixed to the outer upper panel 206. Thus, the area covered by the reinforcing tab 202 has a three-layer structure. The descending partition 210 has an upper edge defined by the punched part 212. Reinforcement tabs 214 on the inner top panel 204 reinforce the handle region 216 to some extent, but the only problematic regions located to the left and right of the handle opening 208 are the single layer paperboard (outer upper panel 206).

As described above, the following can be understood by comparing FIG. 3 and FIG. That is, the thickness around the handle openings 34, 50 and the handle openings 32, 48 is two layers due to the handle reinforcing portion 54, whereas in the known one as shown in FIG. Has only one thickness. Therefore, while the known shipping container requires 27 points of paperboard, the present invention has at least two layers of thickness, so it is convenient to use a paperboard as thin as 24 points. it can. Thus, the novel structure of the present invention achieves weight reduction and cost reduction.

Although the present invention has been described above with reference to a preferred embodiment,
Without limitation, various modifications and variations can be made within the full intention of the invention as defined by the appended claims.
