Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tray container with crosspieces, which is mainly used as a container for containing a paper container containing liquid beverage such as milk, coffee, juice or liquor. The present invention relates to a shipping container that can replace a conventional plastic container.

[Prior Art] Conventionally, for example, when a large quantity of paper containers containing milk are collectively delivered from a bottling factory of a dairy maker to a retail store, a plastic container (hereinafter, simply referred to as "placon" for short) made as a carton is used. Has been. After being delivered to a store for use, this plastic computer is collected and washed for repeated use. However, if the time and effort required for collection and cleaning work are included, storage and maintenance will require a considerably high cost.
To alleviate this difficulty, manufacturers, distributors, and retailers have recently strongly demanded the development of a one-way type corrugated cardboard container that can replace the above-mentioned plastic converter.

[Technical problem] When designing a container for carrying a paper container containing milk, the strength of the container must be set in consideration of the low strength of the paper container itself. This is because if the strength of the container is insufficient, the paper container, which is the object to be packaged, may be crushed due to a drop impact or the like, and the paper container may be damaged to cause liquid leakage. In addition, the paper container may gradually become fatigued due to vibration and resonance during transportation and pinholes may be formed in the container, and liquid leakage may occur from there, so it is necessary to take measures against this point. Of the containers containing liquid beverages, milk containers in particular tend to have longer delivery distances, so it is necessary to design the containers with due regard to the above points.

By the way, the one-way type container, unlike the plastic container as a returnable container, is disposable only once and is not used repeatedly. Therefore, the one-way type container is structurally not required to have the same strength and durability as the plastic container. But,
Since milk containers and the like need to be transported at a constant cold temperature, they are usually stacked in multiple stages and transported by a cold carrier or the like. For this reason, during transportation, dew condensation may occur in the container, so it is necessary to drain the milk container contained in the container so that the dew condensation does not stain the milk container and the dew condensation water does not collect in the container. Further, after transportation and storage, there is also a demand for having a function of being able to stack the product in a predetermined exhibition space and store it in a container when the product is sold at a retail store or the like.

[Object of the Invention] The present invention has been made in order to satisfy the above-mentioned demands, and has a simple structure and excellent strength, and the outer containers stacked at the time of transportation rattle due to vibration during transportation. The purpose is to provide a tray container with a crosspiece that can prevent the cargo from collapsing and can be quickly drained when condensation occurs.

[Means for Solving Problems] In order to achieve the above-mentioned object, the present invention provides a rectangular bottom plate having a rectangular shape.
In a quadrangular tubular container in which a pair of side plates and a pair of end plates are continuously provided so as to face each other, side flaps, reinforcing flaps, and joining flaps are sequentially provided on the extension of both sides of the end plate through fold lines. A projection is integrally provided on the upper end of the joining flap on the front end side, and a crosspiece having a pair of upper flaps at both ends is continuously provided on the upper edge of the end plate through a fold line. While providing a protrusion by forming a U-shaped cut corresponding to the protrusion from the center of the fold of the plate, the protrusion and a notch that can be fitted when the containers are stacked are provided from the center of the fold of the end plate and the bottom plate. At the same time, a tray container with crosspieces is proposed, in which a reinforcing flap is bent inside the side flap, a joining flap is joined to the inner surface of the gable plate, and an upper flap and a side plate are joined to the outside of the side flap. What to do Is.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a perspective view showing a completed assembly state of the present invention, FIG. 2 is a plan view of a blank sheet constituting the container of the present invention, and FIG.
The figure is a perspective view showing the assembling process. In FIG. 2, reference numeral 1 is a blank sheet of the container of the present invention formed of a corrugated cardboard sheet. 2 to 4 are panels connected in one direction on the sheet, and in terms of individual functions, reference numeral 2 is a rectangular bottom plate divided into a plurality of fold lines 5 and 6 at the center of the sheet, and 3 and 3 are A pair of end plates 4 and 4 connected to the left and right of the bottom plate 2 so as to be bendable are crosspieces connected to the left and right of the end plate 3 so as to be bent. Reference numerals 7 and 7 denote a pair of side plates that are continuously provided so as to be bendable above and below the bottom plate 2. Reference numerals 8 and 8 denote upper flaps that are vertically arranged so as to be bendable above and below the cross plate 4. Further, reference numerals 9 and 9 denote side flaps which are continuously provided so as to be bendable above and below the end plate 3, and a reinforcing flap 12 having the same width as the side flap 9 is provided on the extension of the side flaps 9 and 9 via folding lines 10 and 11. And the joining flaps 13 are successively connected to the outside thereof. A substantially U-shaped cut 14 is formed in the center of the fold between the end plate and the cross plate, and a projection 15 is provided to project above the cross plate. In addition, a cutout 16 into which the above-mentioned projection 15 is fitted is formed at the fold portion of the end plate and the bottom plate when the containers are stacked. On the other hand, a protrusion 17 to be inserted into the notch 14 is provided on the upper edge of the joining flap 13 on the tip side. Reference numeral 18 is a hand hole for handling formed in the end plate 3 and the joining flap 13. Further, a folding line 19 is engraved in parallel with the folding line 6 leaving a length corresponding to the width of the side flap 9 at both ends of the side plate 7, and notches 20 are provided at both ends thereof to form a folding piece 21.

To assemble the container of the present invention using the blank sheet 1 constructed as described above, as shown in FIG.
The reinforcing flap 12 is bent inside, and the joining flap 13 is adhered to the inner surface of the end plate 3, and then the article to be packaged is placed on the bottom plate 2 (the article to be packaged is not shown). Next, after wrapping the article to be packaged with a blank sheet, the upper flap 8 and the side plate 7 are overlapped and adhered to the outside of the side flap 9 to form a first sheet.
The container shown is completed. It should be noted that there is no problem even if the container already assembled as shown in FIG.

When using the container of the present invention, as described above, the packaged object such as a container containing milk that needs to be transported and stored at a constant temperature is
After being stored in the container having the above structure, it is usually stacked in a number of stages and temporarily stored in a refrigerating warehouse, or is transported by being stacked in a cold storage vehicle or the like during transportation. In this case, handling is required along with transportation, but in that case, it is carried through the hand hole 18 formed in the end plate 3 and the joining flap 13. The hand hole is easy for the hand to enter, and since the part where the finger touches is doubled, it is strong even if a load is applied, and there is little finger pain.

In stacking, the projections 15 and 17 projecting from the cross plate 4 of the lower container are fitted in the notches 16 on the bottom surface of the upper container of the present invention to be stacked on the cross plate. By doing so, when the containers are stacked, the projections 15 and 17 projecting from the cross plate 4 of the lower container fit into the notches 16 on the bottom surface of the upper container to be stacked.
The upper container is prevented from being displaced in the lateral direction and the joining direction. Therefore, play (vibration) during transportation between the upper and lower containers can be reduced.

Also, when transporting in a cold state with the containers of the present invention stacked,
Notches provided at both ends of the bottom plate of each container even if condensation forms in the container
Condensation water flows down quickly from 16 and is discharged to the outside, so that the water that has condensed does not collect at the bottom of the container, and the strength deterioration of the corrugated board due to water absorption can be prevented in advance.

FIGS. 4 and 5 show the stacked state, and in this packaging, the packaged items are collectively delivered from the manufacturer or the like to a store such as a convenience store. After being delivered to the store, they are displayed in the store after being piled up in a predetermined exhibition space inside the store.

In the above embodiment, the reinforcing flap 12 is overlapped with the inner surface of the side flap 9 and the joining flap 13 is adhered to the inner surface of the end plate 3 to have a double structure for reinforcing the corner of the container. However, depending on the shape of the object to be packaged in the container, it is possible to form a reinforcing post having a triangular space with the reinforcing flap 12, the joining flap 13 and the end plate 3 inside the side flap 9 as shown in FIG. Is.

[Effects of the Invention] As described above, when the present invention is used, even if dew condensation occurs in the container, the dew condensation water is quickly drained to the outside through the notch provided on the bottom plate of the container, and the water condensed on the bottom of the container is condensed. Does not accumulate. Therefore, it is possible to prevent the strength of the corrugated board from being deteriorated due to the absorption of the condensed water. In addition, when stacking in multiple stages during transportation, since the protrusion protruding from the cross plate of the lower container fits into the notch on the bottom surface of the upper container to be stacked, the upper container in both the lateral direction and the front-rear direction. Will not be displaced. Therefore, the above fitting reduces vibration between the stacked containers during transportation. Further claim 2
According to the invention described in the above, it is possible to form a durable hand hole on the end plate with less finger pain to improve the handling property, and to provide a one-way type corrugated cardboard container that can replace the conventionally used plastic container. It has a useful effect in that it can.
