Description

Insulation laminate structure

The present invention relates to an appliance having a heat insulating effect and can be assembled into an article, in particular, a laminated structure of the appliance.

For example, Taiwan's new patent No. M556563 is a "laminated structure for making an insulated container". This patent is a product previously developed by the applicant, mainly using a cutter structure with a nip and a blade at the same time. Therefore, when cutting the hair sheet, the nip portion of the cutter is pressed against the foam sheet. At the same time, thermal energy is transferred to the foamed sheet by the nip, and the polymer layer located in the paper layer is indirectly thermally melted to bond the foamed sheet to the polymer layer.

However, the above-mentioned new patents use this method, and the following defects occur in the production process:

First, an additional heater is required to directly or indirectly heat the tool structure. In order to achieve the polymer hot melt temperature, the tool needs to be heated to 100 degrees Celsius to 110 degrees Celsius, which will cause the tool structure to expand and cause the blade deformation to be lost. The original cutting position is accurate, so that the cutting error is enlarged.

Second, when the tool structure is directly or indirectly heated, it is also likely to cause partial hot melt of the tool contacting the foamed sheet, and the foamed sheet is likely to occur. The partial hot melt adheres to the nip portion and the cutting edge of the cutter structure, and the tool structure is not easily separated from the foamed sheet, so that it is inconvenient in operation and use.

Thirdly, the nip portion of the cutter structure is pressed against the foamed sheet due to high temperature, and it is easy to leave an embossed mark on the surface of the foamed sheet, so that the surface of the foamed sheet is not flat enough to affect the subsequent foamed sheet. Surface printing effect.

Fourth, the foamed sheet needs a polymer material containing the same polymer layer material, and thus there is a limitation in the use of the material of the polymer layer and the foamed sheet.

According to the above defects, it is necessary to develop a new type of insulation layer structure in order to meet the needs of the industry's manufacturing.

The present invention provides a novel thermal insulation laminate structure that differs from conventional techniques in the use of hot melt hot compressive indirect polymer layers to avoid the associated drawbacks of conventional techniques.

In order to achieve the foregoing objects and effects, an insulating laminate structure is provided, comprising a substrate layer, a glue layer and a heat insulating layer, wherein: the substrate layer includes an outer peripheral portion and an inner peripheral portion, and surrounds the inner layer a connecting portion of the outer boundary of the circumference, the connecting portion is integrally connected between the inner peripheral portion and the outer peripheral portion; the glue layer has one of the opposite two combined sides disposed on the inner peripheral portion, and a glue layer is not disposed on the outer peripheral portion; the heat insulating layer has an inner circumference portion and a peripheral portion surrounding the inner circumference portion, and an inner surface side of the inner circumference portion is disposed on the other of the two joint sides By.

Referring to the first to fifth figures, the inventive heat insulating laminate structure comprises a substrate layer 10, a glue layer 20 and a heat insulating layer 30, wherein: the substrate layer 10 of the embodiment comprises a peripheral portion. 11 and an inner peripheral portion 12, and a connecting portion 13 surrounding the outer boundary of the inner peripheral portion 12, the connecting portion 13 is integrally connected between the inner peripheral portion 12 and the outer peripheral portion 11; the glue layer 20 One of the opposite two joint sides 21 is disposed on the inner peripheral portion 12, and the glue layer 20 is not disposed on the outer peripheral portion 11; the heat insulating layer 30 has an inner periphery portion 31 and surrounds the inner circumference One of the outer peripheral portions 32 of the portion 31, and an inner surface side 33 of the inner peripheral portion 31 is disposed on the other of the two joined sides 21.

The following procedure is used to fabricate the thermal insulation laminate structure from the flexographic transfer machine 500. First, the transport mechanism 501 winds up the substrate layer 10, and transports the substrate layer 10 to the gumming mechanism 502 so that the inner peripheral portion 12 of the substrate layer 10 is surfaced. Forming a glue layer 20 so that glue The bonding side 21 on one side of the layer 20 is fixed on the surface of the inner peripheral portion 12 of the substrate layer 10, and the insulating layer 30 is attached to the other bonding side 21 of the glue layer 20 by the attaching mechanism 503, and the insulating layer 30 corresponds to the combination. The side 21 is the inner circumference 31, and the non-corresponding side 21 is the outer portion 32.

In the present invention, the insulating layer 30 can be firmly bonded to the inner peripheral portion 12 of the substrate layer 10 through the glue layer 20, so as to avoid the processing error caused by the thermal expansion deformation of the tool generated by the conventional tool structure using hot melt and hot pressing, and the tool is easy to be stained. Stickiness, as well as indentations on the surface, as well as troubles and defects in material selection.
