BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cold-preserving agent, and more particularly to a cold-preserving agent to be attached to the mouth of a milk bottle.

[0002]

2. Description of the Related Art Heretofore, a milk box installed at a home of a delivery destination or a side of an entrance of a business place has been known as a device for temporarily storing a milk bottle when milk is delivered. The milk box is provided with a space for accommodating the milk bottle, and the delivery person who delivers the milk puts the milk bottle in the accommodating space. In addition, the space for storing milk bottles has a structure that allows outside air to easily enter, and most milk boxes are installed outdoors, so the temperature inside this storage space is almost the same as the outside temperature. easy.

[0003] In general, milk is often delivered early in the morning, and the recipient (housekeeper of the recipient's household or an employee of a business establishment) immediately receives the milk, or at least in the morning when the temperature is relatively low. , It is desirable to take the delivered milk indoors. However, if the recipient forgets to take the milk delivered in the early morning into the room, or is out of the room and the milk is left outside for a long time, even if it is stored in the milk box, it will be affected by the outside temperature. It became warm, which could lead to milk spoilage.

Therefore, especially in summer when the temperature is high, the delivery person sometimes puts a cold-preserving agent together with milk in the milk box. The cold insulating material is a resin bag in which a liquid cold insulating material is sealed. Specifically, after freezing the internal cold storage substance in a freezer or the like, by placing it in the vicinity of fresh food products such as meat and seafood that require cold storage, the food can be temporarily kept at a low temperature. It is often used when foodstuffs are transported or sold. Therefore, by putting the ice pack and the milk bottle together in the milk box, it is possible to temporarily prevent the milk from becoming warm.

[0005]

However, since the cold storage agent keeps the milk bottle cold by keeping the temperature in the storage space low, as described above, the storage space tends to have the same temperature as the outside temperature. Inside, it was difficult to keep each milk bottle cold enough. Further, many of the ice packs are generally formed in a flat plate shape and the contact area between the ice pack and the milk bottle is small. Therefore, the ice pack is not suitable for cold storage in which the milk bottle is kept cold.

[0006] Further, the delivery person carries the milk bottle and the ice pack at the time of delivering milk, and collects the empty milk bottle and the used ice pack (melted ice pack) from the milk box. Then
The work of storing the milk bottle filled with milk and the new ice pack (frozen ice pack) in the milk box was troublesome and troublesome. Therefore, what could reduce these works was desired.

Further, since the accommodation space of the conventional milk box is made relatively large with respect to the milk bottle, strong winds, dogs,
When a milk box collapsed by a cat or the like, it sometimes collided with the inner wall of the storage space or another milk bottle. At this time, since the milk bottle is made of glass, the milk bottle may be broken when the impact is severe, and the mouth of the milk bottle is often damaged.

By the way, recently, due to the problem of environmental resource protection, milk delivered in bottles is preferred to milk sold in paper packs. Milk packs are often discarded after the milk has been drunk. on the other hand,
The milk bottles are collected by the delivery person after the milk is drink, washed, and then refilled with milk and delivered to the recipient. In this way, milk bottles are reusable and are being used more frequently because they do not produce waste, so milk bottles can be effectively used in an environment where the temperature tends to be the same as the outside temperature, such as a milk box. There was a need for something that could be stored at cold temperatures.
