Description

  The present invention relates to a heat insulating container for a front cargo bar of a bicycle.

  The front cargo bar of a bicycle is usually a net made of iron wire, and when buying food, the bought food is put in it. Also, when going out to a company, etc., carry a lunch box in it.

  When transporting the food, the food contains a mixture of frozen, refrigerated, and heated items.When they are placed in a single container, they dissipate or absorb heat from each other, and in a cold or warm state. It disappears, and the texture of the food is impaired. Today, the amount of food purchased at one time is large, and the mixed state is becoming intense. For this reason, the frozen / refrigerated product and the heated product are usually separated, for example, the frozen product / refrigerated product is put in the front cargo, and the heated product is put in the rear cargo.

In addition, there is a technique in which a bag made of nylon is fitted to the cargo bag in order to protect the stored item from rain (see Patent Document 1). This bag is used by completely fitting in the front cargo box.

  Today, with the improvement of the living environment, people are paying attention to eating more deliciously, and the mixture of frozen, refrigerated and heated foods degrades the quality of the food, so as far away as possible. I wanted to carry it. This tendency is not limited to distributors, but is similar to general housewives.

  On the other hand, a housewife talks for a long time with a friend or the like in the middle of shopping, or enters a coffee shop and talks for a long time. At this time, the shopping (food) put in the bicycle luggage is often left as it is (see FIG. 16D). In that case, shopping (food) is mixed for a long time, and if frozen or chilled food and heated food are mixed, the quality of the food is deteriorated.

  In addition, today, in commuting, attending school, picnics, etc., lunch boxes and plastic bottles are often carried in the luggage of bicycles. In that case, the lunch boxes should be kept at a temperature suitable for the lunch boxes as much as possible. I want to eat deliciously (see FIGS. 16A and 16C).

  However, conventionally, the front cargo bar of a bicycle is net-like and does not have heat insulation (insulation), and even if the bag described in the above-mentioned publication is fitted to the cargo bag, the bag guarantees heat insulation. Therefore, it is almost impossible to obtain the required heat insulation state.

  This invention makes it a subject to provide heat retention (heat insulation) to the front luggage of the bicycle which can be carried easily.

  In order to achieve the above object, according to the present invention, the cargo itself is constituted by a heat insulating container. If it is an insulated container, for example, if you put shopping food in it, with its heat retention (heat insulation), the temperature of the food, for example, if it is frozen or refrigerated, lower temperature, if it is heated Maintain the warmth, respectively.
