Description

  The present invention relates to a lid that covers an upper part of a container containing dairy products stored in a returnable box, a dessert such as pudding or jelly, a container containing chilled food, or a cup container for other beverages.

Many items such as cupped yogurt, pudding, and jelly are stored in returnable boxes and shipped from factories and warehouses. During distribution, the returnable boxes were often stacked and stacked to transport and store the goods. In order to prevent the contents from being altered, a large number of ventilation holes are opened on the side of the box to introduce cold air into the box, and the box is stored in a cold storage warehouse and also transported by a cold car etc. ing.
Conventionally, a plastic container as shown in the lower part of FIG.

  In recent years, commercially available cupped products such as yogurt, pudding, and jelly have been manufactured with a capacity of about 100 ml for a small one and a capacity of about 300 ml for a large one, for example. When storing and transporting cup-sized products of various sizes, it is economically and administratively wasteful to prepare a plastic container for storing the cup-sized products for each size. is there. Therefore, storing and transporting cup-sized products of different sizes in a common plastic container may be performed.

However, when a cup-made product whose height is higher than its internal height is stored in a ready-made plastic container, there are the following disadvantages. For example, the upper part of the product protrudes from the upper surface of the container. This makes it impossible to stack containers in multiple stages. In addition, when stacked, the upper product weight is directly applied to the lower product, and there is a risk that the product value may be reduced, such as the lower product being damaged or the lower product seal being broken. Further, the upper part of the product may be exposed to sunlight, illumination light, or the like, and the quality of the product may be deteriorated by the light.
Furthermore, the packaging of containers stacked up and down due to vibration during transportation becomes unstable, causing a problem that the container collapses easily.
Therefore, it has been unavoidable to use a plastic container that has a higher internal height than the contents.

  The present invention is intended to solve the above-described conventional problems. In other words, when a cupped product higher than its internal height is stored in a ready-made plastic container, it is possible to stack the container in multiple stages, and when stacked, the upper product weight is added to the lower product. Prevents damage or tearing of the lower product lid seal and shields the upper part of the cupped product to prevent the upper part of the product from being exposed to light, and also prevents collapse of goods during transportation and chilled transportation It is intended to provide a lid for a returnable box that does not impede the cooling effect.

In order to solve the above-mentioned problem, the present invention is a lid for a returnable box used when transporting a cupped product stored in a returnable box.
The lid according to the present invention is located in the upper opening of the return box, and passes through the substantially rectangular upper face plate that covers the upper face of each cupped product that is stored in the return box and forms a row, and from both side edges of the upper face plate. It has a pair of side plates that are bent and face each other in parallel to the inner side surface of the box. The side plate has a height dimension equal to or higher than the height of the cupped product, and a pair of legs are provided in the side plate with ventilation notches, and the upper plate is adjacent to the cup. A claw portion to be inserted between the incoming products is formed.

  In the lid according to the present invention, stacking protrusions protruding above the side plate are provided on both side edges of the upper surface plate.

  Furthermore, the lid according to the present invention is characterized in that a product identification window is provided on the top plate.

In the lid of the present invention, when a product in a cup is put in a passing box and shipped and transported, an upper surface plate is disposed on each cupped product in a row accommodated in the passing box. Further, a pair of side plates that are bent from both side edges of the upper surface plate are inserted so as to be parallel to the inner side surface of the box, and the upper surface plate is attached to the upper opening of the pass box.
At this time, the top plate and the cup lid seal portion may be brought into contact with each other, and a slight space (gap) is formed between the top plate and the cup lid seal portion so that the leg portion at the bottom of the side plate is It is configured to abut against the inner bottom of the returnable box. The top plate and the lid sealing part of the cup are brought into contact with each other, or a space is provided, and the size of the space is adjusted by appropriately setting the length of the leg portion.

  Therefore, when the lid of the present invention is attached to the upper opening of the return box, the product is protected from incident light and the like by shielding the upper surface and the left and right side surfaces of each cupped product in the stored row. In the lid of the present invention, the claw portions protruding downward from the upper surface plate are inserted between the products in a row, so that the product and the lid of the present invention are fixed in a predetermined positional relationship. The said claw part has a function which fixes contents, such as a cup, in a returnable box.

  When the returnable boxes are stacked in a plurality of stages and stored and transported in a cool box or a cool car, the lid of the present invention can confirm the type, brand, expiration date, etc. of the product by the product identification window on the upper surface. Further, since the cool air passes through the identification window and the side notch, the cooling effect during chilled transportation is not hindered. Further, since the stacking projections protruding above the side plates are provided on both side edges of the upper surface plate, it is possible to prevent the movement of both by engaging the return boxes stacked vertically with the projections.

  As described above, the lid for the returnable box of the present invention can be easily mounted because it is simply inserted into the upper opening of the returnable box. It is also easy to remove. In addition to preventing the product from being exposed to sunlight, etc., the weight of the upper product is directly lower when stacking the use of containers with containers that are higher in size than the internal method of the return box. In addition, it is possible to prevent the movement of the returnable boxes and the collapse of the cargo. In addition, there is an advantage that it can be stored and transported without impeding the cooling effect during cold transport.

  Since the lid of the present invention is made of paper sheet material, it is not only easy to manufacture and inexpensive, but also allows ready-made plastic containers (return boxes) to be easily adapted to products of various sizes, as well as disposal and recycling. Good and disposable.
