Description

Thermal insulation

The present invention relates to a heat insulating member, and more particularly to a heat insulating member capable of providing a good heat insulating effect for taking a container through the heat insulating member.

Referring to Fig. 1, there is shown a conventional heat insulating member 9 which is a one-piece body, and the two ends of the sheet body are coupled to each other to form the heat insulating member 9 into an annular structure. The heat insulating member 9 includes a heat insulating layer 91 and a surface layer 92. The heat insulating layer 91 is wavy, and the heat insulating layer 91 can be adhered to the surface layer 92 by an adhesive.

Referring to FIG. 2 together, when the heat insulating member 9 is actually used, it is coated on the outside of a container C. Thereby, the heat insulating layer 91 of the heat insulating member 9 can abut against the outer surface of the container C, and the surface layer 92 can be held by the user. Wherein, if the temperature of the contents contained in the container C is high, or the container C is heated by a heating device such as a microwave oven, and the temperature of the contents of the container C is raised, the heat insulating layer 91 is waved. Therefore, the heat insulating layer 91 can be in spaced contact with the outer surface of the container C to prevent the high temperature of the contents of the container C from being directly transmitted to the heat insulating member 9, thereby facilitating the user to pass the The heat insulating member 9 takes the container C while avoiding burns to the high temperature of the contents of the container C.

Although the heat insulating member 9 can provide a high temperature effect of initially isolating the contents of the container C by the above configuration, the heat insulating member 9 is spaced apart from the outer surface of the container C by the heat insulating layer 91. Contacting to reduce the contact area between the heat insulating member 9 and the container C, thereby generating a heat insulating effect. Wherein, the heat insulating layer 91 is wavy, so that the heat insulating layer 91 and the container C will form a long strip contact, resulting in a contact area between the heat insulating member 9 and the container C. However, the heat insulating layer 91 and the surface layer 92 are bonded to each other. Accordingly, once the heat insulating member 9 is in contact with the container C for a long time, the high temperature of the contents of the container C will eventually be conducted to the surface layer 92 of the heat insulating member 9 via the heat insulating layer 91. Therefore, the heat insulating effect of the heat insulating member 9 is rather limited.

Furthermore, please refer to FIG. 1 again, although the heat insulator 9 is not in use. The lower part can be folded to make the heat insulating member 9 easy to stack and store. However, since the heat insulating layer 91 is wavy, the heat insulating layer 91 has a large thickness, and thus the overall volume of the heat insulating member 9 is large, so the heat insulating member 9 is in a standby state or a transport state.

The above and other objects, features and advantages of the present invention will become more <RTIgt; The heat insulating member according to the first embodiment of the present invention comprises a sheet body 1 which can be made of paper, plastic material or other material having toughness. The sheet body 1 has a first direction X and a second direction Y perpendicular to each other, and the two sides of the sheet body 1 in the first direction X can be coupled to each other, so that the sheet body 1 can surround the second direction Y. An annular structure is formed, in other words, the sheet body 1 can be bent into a ring shape with the second direction Y as an axis, so that the sheet body 1 forms the annular structure. The sheet body defines a plurality of cutting lines 12 along the second direction Y, and the cutting lines 12 are spaced apart from each other in the first direction X. Each of the cutting lines 12 includes a plurality of cutting lines 121 extending through the sheet body 1. The plurality of cutting lines 121 are discontinuous, that is, the cutting lines 121 are not connected to each other, and The cutting lines 121 are spaced apart from each other in the second direction Y. The cutting line 121 of any two adjacent cutting lines 12 may be dislocated in the first direction X.

The cutting lines 12 are spaced apart from each other in the first direction X. Therefore, the two adjacent cutting lines 12 can define a heat insulating strip 13 on the sheet body 1, and the heat insulating strip 13 is flat. The surface of the heat insulating strip 13 can form a round angle on each of the two sides in the second direction Y. In other words, the two adjacent heat insulating strips 13 are separated by a cutting line 12, and the plurality of cutting lines 121 included in the cutting line 12 are spaced apart from each other in the second direction Y. The adjacent heat insulating strips 13 can be connected to each other by the portions of the cutting lines 12 of the cutting lines 12 so that the two adjacent heat insulating strips 13 are not separated from each other.

In this embodiment, the plurality of cutting lines 12 may be respectively parallel to the second direction Y. In other words, the plurality of cutting lines 121 included in each of the cutting lines 12 are parallel to the second direction Y. Referring to FIG. 3b, another embodiment of the heat insulating member according to the first embodiment of the present invention, in the embodiment, the sheet body 1 can be on the two sides of the second direction Y. The curved lines 12 are formed in a curved shape. Therefore, the plurality of cutting lines 12 may not be parallel to the second direction Y, that is, the cutting line 12 may form an angle θ with the second direction Y, and any two cutting lines 12 The angle θ formed by the second direction Y may be different. Accordingly, the plurality of cutting lines 121 included in each of the cutting lines 12 may not be parallel to the second direction Y. The "several cutting lines 12 are respectively opened along the second direction Y" according to the present invention. The angle θ formed by the cutting line 12 and the second direction Y is less than 45°, which can be understood by those skilled in the art to which the present invention pertains.

Referring to Fig. 4a, there is shown a use case diagram of the heat insulating member of the first embodiment of the present invention. When the heat insulating member is actually used, the sheet body 1 can be bonded to each other on the two sides in the first direction X by using a tape or a staple, so that the sheet body 1 forms a ring structure; however, in this embodiment A plurality of joint portions 11 are respectively disposed on the two sides of the first direction X. The plurality of cutting lines 12 of the sheet body 1 are disposed between the two joint portions 11 and the joint portion 11 is provided for The adhesive is applied, so that the two joint portions 11 can be butted and bonded to each other, so that the sheet body 1 forms an annular structure. Thereby, the sheet body 1 can be sleeved on the outside of a container C1, and the container C1 can be a cylindrical container (for example, a cup), and the outer surface of the container C1 can be expanded in a longitudinal direction L to make the container The minimum outer diameter of the outer peripheral surface of C1 may be less than or equal to the inner circumference of the annular structure formed by the sheet body 1. The diameter, and the outer diameter of the outer peripheral surface of the container C1 may be larger than the inner diameter of the annular structure formed by the sheet 1. Therefore, the sheet body 1 can be sleeved outside the container C1 from the outermost outer diameter of the outer surface of the container C1. Please refer to FIG. 4b together, since the outer surface of the container C1 is formed along the longitudinal direction L. Expanding the diameter, and the maximum outer diameter of the container C1 is larger than the inner diameter of the sheet body 1. When the sheet body 1 is inserted into the container C1 along the longitudinal direction L, the outer peripheral surface of the container C1 is formed to have a maximum outer diameter. The position of the outer circumference of the container C1 is longer than the circumference of the annular structure formed by the sheet 1, and the sheet 1 will be supported by the outer peripheral surface of the container C1. The sheet 1 is covered and positioned outside the container C1.

In detail, the sheet 1 surrounds the second direction Y to form the annular structure, and the annular structure has a first state and a second state. As shown in FIG. 4a, the annular structure is not subjected to the outer circumferential surface of the container C1 to form the first state, and the annular structure has a first circumference in the first state, the first The circumference is smaller than the circumference of the outer peripheral surface of the container C1. According to this, as shown in FIG. 4b, when the sheet body 1 is inserted into the container C1 along the longitudinal direction L, the sheet body 1 will be supported by the outer peripheral surface of the container C1, so that the ring structure is From the first state to the second state, the annular structure has a second perimeter in the second state, the second perimeter being equal to the perimeter of the outer perimeter of the container C1.

At this time, after the annular structure is changed to the second state, since the sheet body 1 has a plurality of cutting lines 12, the portion of the heat insulating strip 13 connected to the cutting line 121 is subjected to the outer circumference of the container C1. The force of the top support will be deflected away from the container C1 to form a raised rib 13a. In contrast, the portion of the heat insulating strip 13 that is not connected to the cutting line 121 (ie, the portion of the heat insulating strip 13 that is connected to the interval between the two adjacent cutting lines 121 of the cutting line 12) will form a pull. The rib 13b can abut against the outer circumferential surface of the container C1. The cutting line 121 is spaced apart from the second direction Y. Therefore, the rib 13a and the pulling rib 13b are alternately formed on the heat insulating strip 13, so that the heat insulating strip 13 is formed in a three-dimensional wave shape. .

More specifically, please refer to FIG. 5 together, the rib 13a can form a distance D with the outer peripheral surface of the container C1, and the cutting line 121 of the two adjacent cutting lines 12 is at the first A misalignment is formed in the direction X, so that a rib 13a of one of the heat insulation strips 13 can be opposite to a pulling rib 13b of the adjacent another heat insulating strip 13 in the first direction X, so that the rib 13a A gas insulating hole 2 is formed between the pulling rib 13b and the pulling rib 13b of the heat insulating strip 13 and a plurality of gas insulating holes 2 are formed between the rib 13a of the heat insulating strip 13 The gas heat insulating hole 2 penetrates the sheet body 1 and communicates with the through hole of the outer peripheral surface of the container C1.

Wherein, since the heat insulating strip 13 is subjected to the force of the peripheral support of the outer surface of the container C1, the heat insulating strip 13 will generate a reaction force to form the heat insulating strip 13 under the action of Newton's third law. The rib 13b does abut against the outer peripheral surface of the container C1 to ensure that the sheet 1 is firmly coated and fixed to the outside of the container C1. The rib 13a of the heat insulating strip 13 is remote from the end of the container C1 for the user to hold, because the sheet body 1 includes a plurality of heat insulating strips 13, and each of the heat insulating strips 13 respectively forms a plurality of ribs 13a. Therefore, when the user holds the sheet 1, the rib 13a formed by the heat insulating strip 13 can effectively share the pressure applied by the user's hand to avoid excessive deformation of the heat insulating strip 13, thereby ensuring the The sheet body 1 and the container C1 are connected only via the pulling ribs 13b of the heat insulating strip 13. On the other hand, since the heat insulating strip 13 forms a rounded corner 131 on each of the two sides in the second direction Y, the rounded corner 131 can prevent the user from trying to hold the sheet 1 when the moving speed is too fast. The risk of scratching the side edge of body 1.

Therefore, it can be seen that, as shown in FIG. 3a, the heat insulating material of the first embodiment of the present invention has a planar shape in the unused state, and the annular structure formed by the sheet body 1 is Forming the first state, the sheet body 1 is formed into a flat sheet-like structure, which is wavy compared to the heat insulating layer 91 of the conventional heat insulating member 9, so that the heat insulating layer 91 has a large thickness, thereby causing the The overall volume of the heat insulating member 9 is large, and the sheet body 1 of the heat insulating member according to the first embodiment of the present invention has a flat sheet-like structure and thus has a small thickness, and has an effect of reducing the overall volume of the heat insulating member. Thereby, the volume occupied by the heat insulating member in the standby state or the transportation state can be effectively reduced, thereby reducing The storage cost or transportation cost required for the insulation is low.

Furthermore, the heat insulating member according to the first embodiment of the present invention is provided with a plurality of cutting lines 12 spaced along the first direction X on the sheet body 1, and each of the cutting lines 12 includes a plurality of strips extending through the sheet body 1 The cutting line 121 is disposed at intervals in the second direction Y. The insulating strip 13 can be defined on the sheet 1 by using two adjacent cutting lines 12. When the sheet 1 is nested in the container C1, since the outer diameter of the container C1 is larger than the inner diameter of the sheet 1, the circumferential surface of the outer surface of the container C1 will be larger than the annular structure formed by the sheet 1. The first circumference of the first state, the sheet body 1 will be supported by the outer circumferential surface of the container C1, forcing the annular structure to change from the first state to the second state, so that the The heat insulating strip 13 is formed with a plurality of staggered ribs 13a and pulling ribs 13b. The ribs 13a form a distance D from the outer peripheral surface of the container C1, and the pulling ribs 13b can abut the outer peripheral surface of the container C1. The sheet 1 is brought into point contact with the outer peripheral surface of the container C1. Accordingly, the conventional heat insulating member 9 is formed in a long strip contact with the container C via the wavy insulating layer 91, resulting in a large contact area between the heat insulating member 9 and the container C. The sheet body 1 of the heat insulating material according to the first embodiment of the present invention is in point contact with the outer peripheral surface of the container C1, and can effectively reduce the contact area between the sheet body 1 and the container C1, thereby greatly reducing the contents of the container C. The rate at which the high temperature is conducted to the sheet 1 does have an effect of improving the heat insulating effect.

In addition, in the embodiment, the sheet body 1 can be made of paper or plastic material, and the annular structure formed by the sheet body 1 is in the second state, and one of the heat insulating strips 13 of the sheet body 1 is A plurality of gas insulating holes 2 are formed between the rib 13a and the pulling rib 13b of the other heat insulating strip 13, so that the sheet 1 of the heat insulating member includes a plurality of gas insulating holes 2, the gas heat insulating The hole 2 is distributed in the sheet body 1, and the gas heat insulating hole 2 penetrates the sheet body 1 and communicates with the through hole of the outer peripheral surface of the container C1 to allow air to exist in the gas heat insulating hole 2. Since the thermal conductivity of air (about 0.024 W/mK) is lower than the thermal conductivity of the paper or plastic material (about 0.05 W/mK), the container C is held by the user when the conventional heat insulating member 9 is held by the user. The high temperature of the contents The heat insulating material of the first embodiment of the present invention can be insulated by the gas by using the gas insulating hole 2 of the first embodiment of the present invention. The air in the hole 2 effectively slows down the conduction of heat energy to the sheet 1, and indeed has the effect of further enhancing the heat insulation effect.

It is noted that in the present embodiment, the cutting line 121 of the two adjacent cutting lines 12 is dislocated in the first direction X so that the rib 13a of one of the heat insulating strips 13 can be The first direction X is opposite to the pulling rib 13b of the adjacent heat insulating strip 13, so that a plurality of gas insulating holes 2 are formed between the two heat insulating strips 13. The cutting line 121 of the two adjacent cutting lines 12 can form an overlapable misalignment setting in the first direction X, that is, a cutting line 121 of a cutting line 12 is in the first direction X. The upper cutting line 121 overlaps with a cutting line 121 of another adjacent cutting line 12, and the overlapping two cutting lines 121 are opened at different positions in the second direction Y, so that the two cutting lines 121 form an overlapable Misplacement setting. However, the cutting line 121 of the two adjacent cutting lines 12 may also form a non-overlapping misalignment setting in the first direction X, that is, a cutting line 121 of a cutting line 12 is in the first direction. The X is not overlapped with a cutting line 121 of another adjacent cutting line 12, and the invention is not limited thereto. However, in some embodiments of the present invention, the cutting lines 121 of the two adjacent cutting lines 12 may be aligned in the first direction X, and the cutting lines of the two adjacent cutting lines 12 are designed. The 121 has different lengths or shapes, whereby the plurality of gas-insulating holes 2 can be formed between the two adjacent heat-insulating strips 13, so that the cutting lines 12 adjacent to the two adjacent cutting lines 12 are cut off. The line 121 may form a misalignment or alignment in the first direction X, which is not limited in the present invention.

Referring to Fig. 6, there is shown another use case diagram of the heat insulating member of the first embodiment of the present invention. The heat insulating member can be used in addition to the above-described container C1, and can also be used in a box-shaped container C2 (for example, a lunch box). The box-shaped container C2 has a longitudinal direction L and a transverse direction W perpendicular to each other, and the width of the box-shaped container C2 in the transverse direction W is smaller than its length in the longitudinal direction L. According to this, the outer peripheral surface of the box-shaped container C2 is in the lateral direction W. The circumference is smaller than the circumference in the longitudinal direction L, and the circumference of the outer peripheral surface of the box-shaped container C2 in the transverse direction W may be less than or equal to the first circumference of the annular structure formed by the sheet 1. The circumference of the outer peripheral surface of the box-shaped container C2 in the longitudinal direction L may be greater than the first circumference of the annular structure formed by the sheet 1. Therefore, the sheet body 1 of the heat insulating member may be sleeved outside the box-shaped container C2 along the longitudinal direction L, and the circumference of the outer peripheral surface of the box-shaped container C2 in the lateral direction W is less than or equal to the sheet body 1 The first circumference of the formed annular structure, so that the outer peripheral surface of the box-shaped container C2 does not support the sheet body 1, the annular structure can be maintained in the first state, and the sheet body 1 is maintained flat A sheet structure to facilitate stacking and accommodating the box-shaped container C2.

Referring to FIG. 7 together, if the box-shaped container C2 is to be heat-treated by a heating means such as a microwave oven, the sheet body 1 can be first removed from the box-shaped container C2, and the box-shaped container C2 is heated. After the processing is completed, the sheet body 1 is sleeved outside the box-shaped container C2 in the lateral direction W, and the circumferential surface of the outer peripheral surface of the box-shaped container C2 in the longitudinal direction L is larger than that formed by the sheet body 1. The first circumference of the annular structure, so that the outer peripheral surface of the box-shaped container C2 will support the sheet body 1 to change the annular structure from the first state to the second state, thereby promoting the heat insulating strip 13 A three-dimensional wave fold is formed. Thereby, although the box-shaped container C2 may have a high temperature after the heat treatment, the user can still take the box shape as usual by moving the rib 13a of the heat insulating strip 13 away from the end of the box-shaped container C2. Container C2.
