Description

Airtight food container

The present invention relates to the structure of a food preservation box, in particular to an airtight food container made of all-ceramic or glass material.

Food preservation box is one of the common daily necessities in modern society, and it is also an important food container. It can be roughly divided into plastic, glass, ceramic and metal (aluminum alloy and stainless steel) according to different materials. Boxes have advantages and disadvantages. Early plastic containers are mainly made of plastic materials, which are light in weight and cheap in price. If the heat resistance is above 100 degrees Celsius, they can be used for low temperature heating in microwave ovens. The safe plastic material is No. 5 polypropylene, but the plastic material is easy to scratch and residue Food smells and stains are also inconvenient to clean. The metal crisper can withstand high temperature, is more excellent in strength, durable, not easy to stain and absorb aftertaste. It can be heated with an induction cooker or electric pot, but it is not suitable for microwave ovens and ovens. If it does not have an anti-scalding design, it must be taken after heating. Be careful.

Based on the fact that most households currently use microwave ovens or ovens as the main equipment for reheating or cooking food, the crisper made of glass or ceramic material is obviously more suitable for most users' usage habits. The fresh-keeping boxes made of commercially available glass can be divided into two types according to different materials: heat-resistant glass and tempered glass. The raw materials and product demands of the two are different. The former is "borosilicate glass", emphasizing high temperature resistance, not only It can be used as a fresh-keeping box, and can also be used in ovens and electric cookers; the latter is "soda-lime glass", which emphasizes that it is not easy to break due to collision. If it is used as a lunch, it is recommended to choose heat-resistant glass material. The part of the heat-resistant glass bento box can be used for ovens and electric cookers. But there are many lids It is made of plastic PP and can only be used for microwave heating, and the time does not exceed 3 minutes. If you want to cook for a long time, do not cover. The glass crisper is heavier. After heating, it is recommended to take both hands with a dry insulation pad. Do not use a damp cloth to prevent the glass from breaking or slipping due to excessive temperature difference.

The fresh-keeping box basically has a lid, which can be kept in a closed state during normal use, but it should be noted that after refrigeration or heating, it is easy to open the lid because of the temperature change. In the approved Taiwan Patent No. 277245, an improved structure of a bento box is proposed, which includes a box body, a box lid covering the box body, the box lid is also provided with a vent hole and a set of ventilating devices, The ventilation device is installed in the ventilation hole of the box cover. The ventilation device adopts a rotary structure design, and the user can release the airtight state by turning the finger. In addition, the Taiwan Patent No. 578477, which has been approved and announced, proposes a leak-proof and auxiliary opening structure for a lunch box. A silicone gasket is provided on the peripheral edge of the bottom surface of the lid of the lunch box, so that the lid can be sealed when it covers the box body. Leak-proof effect; the lid is provided with a hole, and a valve body made of silicone material is provided in the hole; the valve system seals the hole by the elasticity of the silicone material to prevent gas convection inside and outside the lunch box ; When the cover covering the box body is not easy to open due to negative pressure, then by stretching the valve body to make the hole in an incompletely sealed state, the box cover can be easily separated from the box body. In addition, a new type of patent box structure has been proposed in the Taiwan Patent No. M578477, which includes a lid body, and a chamber is formed on the upper side of the lid body. The chamber is provided with two positioning holes for positioning of the airtight plug The column and its positioning hole are pivotally connected in a displaceable manner, so that the airtight plug can be used to keep the airtight vacuum in the box.

The above several known patented technologies have proposed different air valve structures or devices to release the airtight state of the fresh-keeping box or bento box, and most of the known fresh-keeping boxes or bento boxes use a fastener to close the upper cover and the box body Among them, the air valve structure or device and the snap-in structure are independent of each other, and they need to be operated separately when used, and there are many operation actions.
