Description

an ice pack

technical field

The present application relates to storage containers, and in particular, to an ice pack.

Background technique

In the prior art, in order to ensure airtightness, the ice pack is relatively tight at the zipper, and can only be opened and closed with one pull tab. If there are two pull tabs, there will be a gap where the two pull tabs touch, which will affect the air tightness and heat preservation performance of the ice pack. Existing solutions start from two aspects. On the one hand, the pull tabs in contact with fingers are designed as T-shaped or ring-shaped, which is convenient for fingers to apply force; on the other hand, they avoid opening and closing through zippers, and use other mechanical parts and plastic parts for fastening, so that the ice bag can be opened only by opening the mechanical parts. In addition, in the prior art, the ice bag is kept warm by the cotton lining, but there will be a blind area not surrounded by the thermal insulation cotton at the part of the zipper. The existing solution is to thicken the cotton on the top so that after the ice pack is covered, the cotton just reaches the cotton on the bag body, minimizing the gap between the two. At the same time, in the prior art, due to the material characteristics of the ice pack itself, the weight of the entire ice pack will be relatively heavy. In addition, the use scene of the ice pack is generally to contain beverages and food inside, and the overall weight of the ice pack will be relatively heavy. The existing technology is to reinforce by playing jujube wire at the stressed place.

Therefore, the prior art has the following technical problems: 1. The zipper at the opening and closing of the voltage ice pack is not easy to pull; 2. There is a certain temperature leakage at the zipper of the voltage ice pack, which affects the heat preservation performance; 3. The force on the handle of the voltage ice pack is not good;

Although some existing ice packs have designed some structures that can overcome the poor thermal performance. As disclosed in Patent No. 202022594380.X and publication date 2021.10.15, it specifically discloses that the lower surface of the cover is provided with a protrusion, and the upper surface of the box is provided with a depression. When the cover is placed on the box, the protrusion is embedded in the depression, so that the lid is sealed from the inner space of the box. However, this structure needs to process the box body and the cover body at the same time, and the process is relatively complicated, which increases the production cost to a certain extent.

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in Fig. 1 and Fig. 3, an embodiment of the present application provides a kind of ice bag, comprises: cover body 1 and box body 2; Said box body 2 and cover body 1 are connected by zipper, and described zipper 3 is provided with pull piece 31, and described pull piece 31 extends to both sides with hand-held part 32, and the end surface of described hand-pull part 32 and user's finger contact is arc-shaped surface.

In this embodiment, the cover body 1 and the box body 2 are separate structures, and the cover body 1 and the box body 2 are connected by a zipper 3, that is, the perimeter of the zipper 3 is equal to the perimeter of the cross-section of the ice bag.

In an embodiment of the present application, when the ice pack is placed horizontally, at least the tail of the zipper 3 and the horizontal direction have a first angle α that is not zero.

As shown in FIG. 5 , in one embodiment of the present application, the lower surface of the cover 1 is provided with a protruding portion 11. When the cover 1 is placed on the box 2, the protruding portion 11 is inserted into the box 2 and has an interference fit with the box 2, so that the cover is sealed with the inner space of the box.

As shown in FIG. 2 , in an embodiment of the present application, part of the box body 2 and the cover body 1 are integrally formed to form a connecting portion 6 connecting the box body 2 and the cover body 1 , and the rest of the box body 2 and the cover body 1 are connected through the zipper 3 .

As shown in FIG. 4 , in an embodiment of the present application, a pull ring 33 is hollowed out in the middle of the pull tab 31 , and the end surface of the pull ring 33 that contacts the user's finger is a flat or arc-shaped surface.

In an embodiment of the present application, the ice bag further includes: webbing 4 arranged on both sides of the ice bag, and the webbing has a double-layer structure.

In an embodiment of the present application, when the ice pack is placed horizontally, the webbing and the vertical direction have a second angle β that is not zero.

In an embodiment of the present application, the second included angle β is 3 degrees.

In an embodiment of the present application, the cross section of the box is hexagonal.

As shown in FIG. 6 , in an embodiment of the present application, the cross section of the box body is composed of an equilateral trapezoid 51 and a rectangle 52 or square.

In an embodiment of the present application, the cross section of the box is octagonal.

In this application, an upgrade is made on the basis of the T-shaped pull tab 31 , and the portion of the pull tab of this application that is in contact with the fingers is designed to be arc-shaped, which can better match the fingers. By increasing the contact area with the fingers, the pressure generated by the fingers when pulling the tab is reduced, and the user's feeling of effort when pulling the tab is alleviated. In addition, when the user opens the ice pack, the usual usage scenario is that the ice pack is standing on the ground, and the person bends down or squats to open the ice pack. Generally, in this case, the direction of the force applied to unzip the ice pack is not in the same horizontal line as the direction of the ice pack zipper. Therefore, only a small part of the force exerted by the user can effectively act on the opening and closing of the zipper. In this application, the inclination α is designed at the beginning and end of the zipper, so that when the user opens and closes the product, the direction of force is close to the direction of the zipper, and the user's force can be more effectively applied to the zipper. However, it is not limited thereto. Zippers can also be provided with an inclination angle with the horizontal direction.

Optimize the shape of part of the inner lining. The protrusion 11 is only designed on the top cotton. When the product cover is closed, the protruding part 11 of the cover is inserted into the box body 2 and has an interference fit with the inner wall of the box body 2, which can not only effectively reduce the loss of temperature, reduce the gap between the two, but also simplify the structure and process, thereby reducing costs.

This application greatly increases the stress of the webbing handle through the superposition design of the double-layer webbing. On the other hand, the webbing at the front and rear parts is inclined at an angle of 3° relative to the vertical plane, and follows the direction of the force of the handle, which can ensure the beauty of the product, and at the same time, the date line can more effectively act on the direction of force.

In this application, by changing the overall shape, the shape is hexagonal, and the first half is designed as a trapezoid (which may be isosceles trapezoidal or not), so that the internal storage space of the product can better match the characteristics of misalignment when the cans are stacked, thereby improving the utilization rate of the internal space.

1. It is easier to open the zipper without affecting the thermal insulation performance.

2. Improve the fit of the cotton at the zipper and improve the thermal insulation performance.

3. Improve the firmness of the webbing, improve the durability of the product, and increase the service life of the product.

4. The space is effectively utilized, and the product with the same capacity has a smaller shape.

The above descriptions are only preferred embodiments of the present application, and are not intended to limit the present application. For those skilled in the art, there may be various modifications and changes in the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the protection scope of this application.
