Compound thermal keeping bag
A compound thermal keeping bag comprises an upper cover having outer threads and at least one ear for rotating the cover; a silica gel washer enclosing; a sleeve having inner threads; the sleeve can be locked to the upper cover and lock the washer; a center of the sleeve having an opening; a waterproof sealing ring having double face films at two sides of the waterproof sealing ring; the outer double face film serves to be combined with a water and heat proof cloth; the water and heat proof cloth formed as a bag for receiving ice bricks or hot water so as to provide the function of warm keeping; a buckling ring arranged at an outer surface of the water and heat proof cloth; and a heat endurable rubber ring arranged at an outer surface of the buckling ring.
The present invention relates to thermal keeping bags, and in particular to a compound thermal keeping bag, where heat can be isolated effectively so that the temperature of the thermal keeping bag can be retained for a long time with fading. Thereby a ring is used so that user can hold the bag without being hurt. Thereby the thermal keeping bag is matched to the requirement of environment protection and is cost-saved.
BACKGROUND OF THE INVENTIONReferring to
Accordingly, the primary object of the present invention is to provide a compound thermal keeping bag, where heat can be isolated effectively so that the temperature of the thermal keeping bag can be retained for a long time without fading. Thereby a ring is used so that user can hold the bag without being hurt. Thereby the thermal keeping bag is matched to the requirement of environment protection and is cost-saved.
To achieve above objects, the present invention provides a compound thermal keeping bag which comprises an upper cover having outer threads and at least one ears for rotating the cover; a silica gel washer enclosing the threads of the upper cover having the effect of drainproof; a sleeve having inner threads; the sleeve can be locked to the upper cover and lock the washer; a center of the sleeve having an opening; a waterproof sealing ring having double face films at two sides of the waterproof sealing ring; wherein when the waterproof sealing ring is combined to the sleeve, the waterproof sealing ring will not slide out; the outer double face film serves to be combined with a water and heat proof cloth; a water and heat proof cloth formed as a bag for receiving ice bricks or hot water so as to provide the function of warm keeping; a buckling ring arranged at an outer surface of the water and heat proof cloth so that the water and heat proof cloth is tightly engaged to the sleeve; the waterproof sealing ring serves to fill the gaps induced from the water and heat proof cloth and the buckling ring; and a heat endurable rubber ring arranged at an outer surface of the buckling ring.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to
An upper cover 1 has outer threads and at least one ear.
A silica gel washer 2 encloses the threads of the upper cover 1 having the effect of drainproof.
A sleeve 3 has inner threads. The sleeve can be locked to the upper cover 1 and lock the washer 3. A center of the sleeve 3 has an opening.
A waterproof sealing ring 4 are arranged with double face films 5 at two sides of the waterproof sealing ring 4. When the waterproof sealing ring 4 is combined to the sleeve 3, the waterproof sealing ring 4 will not slide out. The outer double face film 6 serves to be combined with a water and heat proof cloth 7.
A water and heat proof cloth 7 is formed as a bag for receiving ice bricks or hot water so as to provide the function of warm keeping.
A buckling ring 8 is arranged at an outer surface of the water and heat proof cloth 7 so that the water and heat proof cloth 7 is tightly engaged to the sleeve 3. The waterproof sealing ring 4 serves to fill the gaps induced from the water and heat proof cloth 7 and the buckling ring 8.
A heat endurable rubber ring 9 is arranged at an outer surface of the buckling ring 8 so that the user can hole the thermal keeping bag 10 (referring to
Referring to
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
Claims
