Abstract

The utility model discloses a foamed bladder, which comprises a bladder layer that is compounded with a foamed layer outside, wherein the bladder layer can be integrated with the foamed layer, and can be made of rubber, or thermoplastic polyurethane, or PVC. The foamed layer can be made of rubber, or thermoplastic polyurethane, or PVC, which is added with foaming agents. Because the outside foaming layer is added, the bladder can be limited by inert foaming material and can be prevented from continuously expanding, therefore the effect of yarn winding, or cloth attachment, or the effect as a middle tyre can be reached. Besides, because the surface of the utility model is a foaming layer, the utility model feels comfortable and soft. The thickness and hardness of the foaming layer can be regulated, and the colors of the foaming layer can be freely changed and matched. The utility model not only can be used as a bladder for balls, such as machine sewing balls, hand sewing balls, or all of other balls which need to be loaded in a bladder, but also can be used as a finished ball article for direct sale and forming a multifunctional article.

Description

The foaming inner bag

Technical field

The utility model relates to a kind of inner bag, and particularly a kind of skin is surrounded by the foaming inner bag of foaming layer.

Background technology

At present, the mode of production of inner bag by 1, direct type inner bag, promptly directly add sulphur and form with mould; 2, twine yarn type inner bag, promptly be wrapped with yarn on the surface of inner bag; 3, patch type inner bag promptly sticks one deck cloth on the surface of inner bag; 4, middle fetalism inner bag, promptly the inner tube of a tyre is added one deck crust rubber after adding and twining yarn, and the mode that becomes similar sandwich is gone control, and it is big not allow inner bag rise when inflation.For direct type inner bag, it is big to continue to rise along with the increase of air, and for twining yarn type, patch type and middle fetalism inner bag, although overcome when inflation inner bag big problem that rises, but since outer by patch or twine yarn, feel soft inadequately comfortable, and feel is not fine.

The utility model content

At the shortcoming that above-mentioned prior art exists, inner bag can not rise greatly when the purpose of this utility model was to provide a kind of inflation, and the soft more comfortable foaming inner bag of feel.

The technical solution adopted in the utility model is: a kind of foaming inner bag, it comprises bladder layer, is compounded with foaming layer outside bladder layer.

Described bladder layer and foaming layer are structure as a whole.

Described bladder layer is rubber, thermoplastic polyurethane, PVC.

Described foaming layer for the bladder layer same material in add blowing agent and make.

Foaming inner bag of the present utility model, owing to added outer field foaming layer outside the tank, the material that utilizes inertia to foam can limit inner bag makes it can not continue to rise greatly, can reach and twine yarn or patch or middle fetalism effect, in addition because top layer own is foaming layer, can feel comfortable softness, both can be used as in sewing or ball sewed by hand or other inflatable inner bag ball and also can form polyfunctional commodity separately as the ball commodity direct marketing of general finished product.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Description of drawings

Fig. 1 is a cross-sectional view of the present utility model.

The specific embodiment

Foaming inner bag as shown in Figure 1, comprise bladder layer 1 and the foaming layer 2 that is compounded in outside the bladder layer 1, bladder layer 1 used material is a rubber, thermoplastic polyurethane, PVC or other can be made the material of inflatable inner bag, outer field foaming layer 2 is selected for use and inner bag material identical materials, add that blowing agent constitutes, so at high temperature, the bladder layer 1 of outer field foaming layer 2 internal layers can be combined into one, become a foaming inner bag, also owing to added outer field foaming layer, utilize the material of inertia foaming can limit inner bag, making it can not continue to rise greatly, can reach the effect that twines yarn or patch or middle tire, is foaming layer because of surface own in addition, can feel comfortable and soft, the thickness of foaming layer and soft durometer can have more to be needed to adjust, and color also can be arranged in pairs or groups in free conversion, not only can be used as the sewing ball, pack into the ball inner bag of inner bag of ball sewed by hand or other any need, also can form polyfunctional commodity separately as the ball commodity direct marketing of finished product.

Foamed bladder of the present utility model has the following advantages: 1, and the ball foaming table of making Layer tool pliability is used to have comfort level and protectiveness; 2, because of the constraint of foaming body, can fall The interior pressure of low outer cortex is subjected to power, makes sewing or hand suture can not reduce intensity because being pressed, and improves Service life; 3, the multiplying power of bump power, elasticity increase and foaming can need according to outward appearance or the client of ball Ask and adjust its soft durometer; 4, become the product process and generally twine yarn or patch is identical, cost does not increase, And do not need to increase yarn or the patch machine of twining, reduce cost of equipment.
