Description

Dog ice pack

technical field

The utility model relates to a heat preservation device, in particular to a phase change material heat preservation bag, in particular to a multi-grid ice bag.

Background technique

Phase change material (PCM, Phase Change Material) refers to a substance that changes shape with temperature and can provide latent heat. The process of a phase change material changing from solid to liquid or from liquid to solid is called a phase change process. At this time, the phase change material will absorb or release a large amount of latent heat.

Phase change materials can be divided into organic (Organic) and inorganic (Inorganic) phase change materials. It can also be divided into hydrated (Hydrated) phase change materials and waxy (Paraffin Wax) phase change materials. Sodium acetate trihydrate, sodium sulfate decahydrate, paraffin is a kind of phase change material.

The ice packs in the prior art are mostly independent individual packages, and the contact surface with the object to be kept warm is basically planar, while many objects to be kept warm are three-dimensional objects, such as bento boxes, which need to be equipped with ice packs on multiple sides, so using independent A single packaged ice pack cannot achieve good heat preservation, and setting multiple independently packaged ice packs on different sides of the object to be kept warm will cause inconvenience in use.

Utility model content

Aiming at the defects in the prior art, the purpose of this utility model is to provide a multi-compartment ice bag.

According to one aspect of the present invention, a multi-compartment ice bag is provided, which includes a film body, and at least two airtight independent capsules are arranged in the film body, and the capsules are filled with phase-change materials.

Preferably, the film body is strip-shaped.

Preferably, the membrane body between adjacent independent capsules is provided with indentations.

Preferably, the extension direction of the dent is perpendicular to the length direction of the film body.

Preferably, the projection of the capsule body on the surface where the film body is located is rectangular.

Preferably, the film body is made of pure PE or PVC.

Preferably, the film body is formed by folding a piece of film in half, and the edge region of the film is provided with grid-shaped indentations.

Preferably, the edge region of the film body is provided with grid-shaped indentations.

Preferably, the plurality of independent capsules are distributed in rows and columns, and the intervals between adjacent independent capsules are equal.

In the utility model, a plurality of capsules are filled with phase-change materials in the film body, so that along with the bending of the film body, the plurality of capsules can form a curved surface (such as a ring surface), so that multiple surfaces of the thermal insulation can be provided. Ice application is convenient to use, and each capsule is not connected to each other, so the film body can be cut according to the needs of use to suit the size of the object to be kept warm.

Detailed ways

The multi-compartment ice bag provided according to the utility model includes a film body 1, and at least two airtight independent capsules 2 are arranged in the film body, and the capsules are filled with phase-change materials. The film body is strip-shaped, as shown in FIG. 1 . The film body between the adjacent independent capsules is provided with dents 4 , and the extension direction of the dents is perpendicular to the length direction of the film body.

More specifically, the projection of the capsule body on the surface where the film body is located is rectangular. The film body is made of pure PE. The edge region of the film is provided with grid-shaped indentations 3 . The film body is formed by folding a piece of film in half. The plurality of independent capsules are distributed in rows and columns, and the intervals between adjacent independent capsules are equal.

Wherein, in the embodiment shown in FIG. 1 , the film body 1 is in the shape of a strip, and a single row and three rows of three independent capsule bodies 2 are arranged along its length direction, which can be called a three-compartment ice pack. Dimples 4 are arranged on the film body between the adjacent independent capsules, so that, on the one hand, the film body 1 can be easily bent along the indentation 4; on the other hand, the The indentation 4 is convenient for the user to use scissors to cut the film body 1 along the indentation 4 , for example, the three ice packs shown in FIG. 1 can be cut into two ice packs.

Those skilled in the art understand that 9 ice packs in the form of a single row and nine columns can be set in the film body when leaving the factory, and users can cut them to obtain ice packs with the corresponding number of grids according to their needs. When the independent capsule is broken, as long as the ruptured independent capsule is cut off, the use of other independent capsules will not be affected, and the service life of the product is improved.

Further, the edge region of the film is provided with grid-shaped indentations, which can increase the coefficient of friction and prevent slipping. The arrangement of equal distances between the adjacent independent capsules can make the present invention facilitate uniform stress on each of the independent capsules when bent into a ring shape. The strip-shaped design of the film body is convenient for the utility model to wrap around the object to be kept warm in an annular shape.

Fig. 3 shows a principle diagram of using a multi-compartment ice pack wrapping around a lunch box according to a specific embodiment of the present invention. Wherein, in this specific embodiment, the utility model is 4 grid ice packs, and these 4 grid ice packs are surrounding the lunch box 5, so that the upper surface, the lower surface, the front surface, and the rear surface of the lunch box 5 have ice packs for cold compress. If use the ice bag of single package in the prior art, then need to be respectively provided with an ice bag on the above-mentioned four surfaces of bento box, one of its weak point is to need rope to fix ice bag, the 2nd, there is gap between ice bag and is unfavorable for heat preservation. In a variation of this specific embodiment, when the number of ice packs increases, for example, there are 9 ice packs, the bento box can be wrapped several more times to increase the heat preservation effect.

The specific embodiments of the present utility model have been described above. It should be understood that the utility model is not limited to the above-mentioned specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the utility model.
