The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item preceding the word comprises the element or item listed after the word and its equivalent, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

As shown in fig. 1 to 3, an embodiment of the present invention discloses an ice cream packaging cover including a cover body 10 and an aluminum silicate film 20, the aluminum silicate film 20 being combined with the cover body 10 and being combined at a factory where the packaging cover is manufactured, rather than being combined at a use site of the packaging cover (e.g., rather than being combined at a packaging site of ice cream).

The cover body 10 is formed by punching a polypropylene film to obtain a main body portion 11 and an edge fastening portion 12 located at the periphery of the main body portion 11, and when the cover body 10 is punched, a recessed groove 111 is punched in a rectangular region of the upper surface of the cover body 10, and the depth of the recessed groove 111 is about 0.1mm to 0.15 mm. When in use, the buckling part 12 of the cover body 10 is used for being clamped with the outer edge of the upper end of the ice cream cylinder so as to cover the upper end of the ice cream.

The aluminum silicate film 20 (purchased by outsource) is cut to have a size identical to that of the embedded sinking groove 111, and the cut aluminum silicate film 20 is disposed in the embedded sinking groove 111 and then combined with the bottom of the embedded sinking groove 111 of the cover body 10.

In some preferred embodiments, the aluminum silicate diaphragm 20 is bonded to the bottom of the recessed groove 111 by adhesive bonding.

In some more preferred embodiments, the aluminum silicate diaphragm 20 is combined with the bottom of the insert recess 111 in the following way:

the aluminum silicate membrane 20 is placed in the embedded sinking groove 111, and the aluminum silicate membrane 20 is extruded by a heating pressure head having the same shape as the embedded sinking groove 111, so that the aluminum silicate membrane 20 is hot-melted with the embedded sinking groove 111, thereby realizing the combination of the aluminum silicate membrane 20 and the upper surface of the cap body 10.

In some preferred embodiments, the ratio of the thickness H1 of the aluminum silicate membrane 20 to the thickness H2 of the corresponding body portion 11 where the sink 111 is embedded is greater than 1. In this way, it is ensured that the aluminum silicate film 20 has a thickness that is satisfactory for coding and has a sufficient heat-conducting medium.

When the ice cream packaging cover is used, the ice cream packaging cover is buckled at the upper end of the ice cream cylinder filled with ice cream, and then the date code 30 (such as the production date code 30) is printed on the aluminum silicate membrane 20 of the ice cream packaging cover by utilizing an ultraviolet laser coding machine or a carbon dioxide laser coding machine.

Since the aluminum silicate film 20 has a characteristic of having a lower melting point than the cap body 10 made of polypropylene, clear writing can be shown on the aluminum silicate film 20 although the energy of the light emitted from the ultraviolet laser marker is low.

Although the energy of the light emitted from the carbon dioxide laser marker is high, since the aluminum silicate film 20 has better thermal conductivity than the cap body 10 made of polypropylene, the excessive heat received by the aluminum silicate film 20 is conducted in the laying direction of the aluminum silicate film 20, and only a small amount of heat is transferred to the cap body 10 in the thickness direction, so that the ice cream under the cap body 10 is not marked.

The ice cream packaging cover provided by the utility model has the advantages that:

the ultraviolet laser coding machine and the carbon dioxide laser coding machine are utilized to code on the ice cream packaging cover, clear writing can be obtained, and the ice cream below the ice cream packaging cover can not be melted to generate marks.
