Description

Technical Field

[0001] The invention relates to tableware, in particular to tableware with a heat-insulating layer. Background Art

[0002] Tableware, such as bowls, is a common dining utensil in daily life. With the continuous development of social economy and the continuous improvement of people's health awareness, children's tableware has begun to appear and gradually become popular. Children's tableware currently sold on the market includes a stainless steel inner shell, a plastic outer shell and a rotating shell with a handle. The inner shell has a containing space for containing food, and the outer shell has a holding space for installing the inner shell and containing hot water. After the hot water and the inner shell are installed in the holding space of the outer shell, the hot water can surround the inner shell due to the squeezing of the inner shell, and the rotating shell can rotate the inner shell and the outer shell to prevent the inner shell and the outer shell from being separated when the user uses the children's tableware. The hot water retained in the retaining space of the outer shell and surrounding the inner shell can achieve a certain heat preservation effect. However, since the outer shell of the children's tableware is designed to be made of plastic material to improve the drop resistance of the children's tableware, the heat of the hot water can be quickly radiated outward through the outer shell, which leads to low utilization rate of the heat of the hot water, thus affecting the heat preservation effect of the children's tableware, especially resulting in a short heat preservation time of the children's tableware.

[0038] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0039] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0040] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0041] With reference to the accompanying drawings of the present invention Figures 1 to 4In the following description, a tableware with a heat-insulating layer according to a preferred embodiment of the present invention is disclosed and explained, wherein the tableware with a heat-insulating layer comprises a heat-insulating outer shell 10 and a food container 20, wherein the heat-insulating outer shell 10 has a holding space 101 and a top opening 102 connected to the holding space 101, wherein the food container 20 can be installed in the holding space 101 through the top opening 102 of the heat-insulating outer shell 10, or the food container 20 can be taken out from the holding space 101 through the top opening 102 of the heat-insulating outer shell 10.

[0042] The material of the food container 20 can be stainless steel to allow the food container 20 to have a good thermal conductivity. Hot water can be added to the holding space 101 of the heat-insulating shell 10. After the holding space 101 of the heat-insulating shell 10 is added with hot water, the food container 20 can be installed in the holding space 101 of the heat-insulating shell 10. At this time, the food container 20 will squeeze the hot water held in the holding space 101 of the heat-insulating shell 10 to raise the liquid level of the hot water, so that the hot water held in the holding space 101 of the heat-insulating shell 10 can wrap around and at the bottom of the holding space 101 installed in the heat-insulating shell 10. The heat of the hot water can radiate toward the food container 20 to extend the heat preservation time of the food contained in the food container 20.

[0043] Furthermore, the thermal insulation shell 10 includes a shell interior 11, a shell exterior 12, and a thermal insulation layer 13 maintained between the shell interior 11 and the shell exterior 12, wherein the thermal insulation layer 13 is used to prevent the heat of the hot water added to the holding space 101 of the thermal insulation shell 10 from radiating outward through the shell exterior 12, thereby allowing the hot water to maintain a higher temperature for a longer period of time.

[0044] In the attached Figures 1 to 4 In this specific example of the tableware with the heat-insulating layer shown, the shell interior 11, the shell exterior 12 and the heat-insulating layer 13 are assembled together to form the heat-insulating outer shell 10. Specifically, when making the tableware with the heat-insulating layer, first, the shell interior 11, the shell exterior 12 and the heat-insulating layer 13 are provided separately; second, when the shell interior 11 is nested in the concave cavity of the shell exterior 12, the heat-insulating layer 13 is maintained between the shell interior 11 and the shell exterior 12; then, the shell interior 11 and the shell exterior 12 are fixedly connected so that the shell interior 11, the heat-insulating layer 13 and the shell exterior 12 form a whole to obtain the heat-insulating outer shell 10.

[0045] It is worth mentioning that the material of the thermal insulation layer 13 is not limited in the tableware with a thermal insulation layer of the present invention, as long as it has good thermal insulation performance. For example, the material of the thermal insulation layer 13 can be but is not limited to aluminum film.

[0046] Preferably, after the shell interior 11 is nested in the concave cavity of the shell exterior 12 so that the thermal insulation layer 13 is maintained between the shell interior 11 and the shell exterior 12, the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 are fixedly connected so that the shell interior 11, the thermal insulation layer 13 and the shell exterior 12 form a whole.

[0047] It is worth mentioning that the method of fixing the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 is not limited in the tableware with a thermal insulation layer of the present invention. For example, the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 can be fixed by glue bonding, or the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 can be fixed by ultrasonic welding.

[0048] Preferably, the insulation layer 13 is bonded to at least one of the shell interior 11 and the shell exterior 12, so that when the tableware with the insulation layer is used, the relative positions of the shell interior 11, the shell exterior 12 and the insulation layer 13 can be prevented from changing and affecting the insulation effect of the tableware with the insulation layer.

[0049] In the tableware with the thermal insulation layer of the present invention, the thermal insulation layer 13 surrounds the retaining space 101 of the thermal insulation shell 10 and wraps the bottom of the retaining space 101, so that after the food container 20 is installed in the retaining space 101 through the top opening 102 of the thermal insulation shell 10, the hot water added to the retaining space 101 of the thermal insulation shell 10 surrounds the food container 20 and wraps the bottom of the food container 20. At the same time, the thermal insulation layer 13 surrounds the retaining space 101 of the thermal insulation shell 10 and wraps the bottom of the retaining space 101. In this way, the thermal insulation layer 13 can prevent the heat of the hot water from radiating outward through the shell exterior 12, and only allows the heat of the hot water to radiate toward the direction of the food container 20, thereby extending the insulation time of the tableware with the thermal insulation layer for the food contained in the food container 20.

[0050] Furthermore, the tableware with the heat-insulating layer includes a protective ring 30, wherein the protective ring 30 locks the food container 20 and the heat-insulating shell 10, so that when a user (especially a child) uses the tableware with the heat-insulating layer, on the one hand, the protective ring 30 can prevent the food container 20 from being separated from the heat-insulating shell 10, and on the other hand, the protective ring 30 can prevent hot water from flowing out of the holding space 101 of the heat-insulating shell 10. In addition, the protective ring 30 can be provided with at least one handle to facilitate the user to use the tableware with the heat-insulating layer.

[0051] Attached Figure 3A The invention shows a manufacturing process of the heat-insulating outer shell 10 of the tableware with the heat-insulating layer, and the manufacturing process specifically includes the following steps: (a) the shell interior 11, the shell exterior 12 and the heat-insulating layer 13 are provided separately, wherein the shell interior 11 and the shell exterior 12 are both bowl-shaped structures to allow the heat-insulating outer shell 10 to be formed into a bowl shape after the shell interior 11 is nested in the concave cavity of the shell exterior 12, wherein the heat-insulating layer 13 is a circular flat plate structure, for example, the heat-insulating layer 13 with a circular flat plate structure can be obtained by cutting a whole piece of aluminum film; (b) the heat-insulating layer 13 is placed in the concave cavity of the shell exterior 12, at which time, glue can be applied to at least one of the side of the heat-insulating layer 13 facing the shell exterior 12 or the side of the shell exterior 12 for forming the concave cavity, so as to facilitate subsequent gluing. (c) nesting the shell interior 11 in the concave cavity of the shell exterior 12, at which time, the shell interior 11 squeezes the insulation layer 13 to deform the insulation layer 13, so that the insulation layer 13 is maintained between the shell interior 11 and the shell exterior 12, wherein before nesting the shell interior 11 in the concave cavity of the shell exterior 12, glue can be applied to at least one of the sides of the insulation layer 13 facing the shell interior 11 or the outside of the shell interior 11, so as to facilitate the subsequent bonding of the insulation layer 13 and the shell interior 11; (d) fixing the top edge position of the shell interior 11 and the top edge position of the shell exterior 12, so that the shell interior 11, the insulation layer 13 and the shell exterior 12 form a whole to obtain the thermal insulation shell 10.

[0052] Attached Figure 3B Another manufacturing process of the heat-insulating shell 10 of the tableware with the heat-insulating layer is shown. Figure 3A The manufacturing process of the heat-insulating shell 10 shown in the figure is different in that Figure 3BIn the manufacturing process of the thermal insulation outer shell 10 shown, after cutting a whole piece of aluminum film to obtain the thermal insulation layer 13 with a circular flat plate structure, the thermal insulation layer 13 is deformed by molding so that the shape of the thermal insulation layer 13 matches the shapes of the shell interior 11 and the shell exterior 12. In this way, after the shell interior 11 is nested and fixed in the concave cavity of the shell exterior 12 so that the thermal insulation layer 13 is retained between the shell interior 11 and the shell exterior 12, the thermal insulation layer 13 can be evenly arranged around and at the bottom of the retaining space 101 of the thermal insulation outer shell 10, so that the thermal insulation outer shell 10 can provide a consistent thermal insulation effect around and at the bottom of the food container 20.

[0053] Attached Figure 3C Another manufacturing process of the heat-insulating shell 10 of the tableware with the heat-insulating layer is shown. Figure 3A The manufacturing process of the heat-insulating shell 10 shown in the figure is different in that Figure 3C In the manufacturing process of the thermal insulation shell 10 shown, after cutting the entire piece of aluminum film to obtain the thermal insulation layer 13 with a circular flat plate structure, a plurality of "V"-shaped notches are further cut out along the circumferential direction of the thermal insulation layer 13, so that in the process of nesting the shell interior 11 in the concave cavity of the shell exterior 12, the two edges of the thermal insulation layer 13 forming the "V"-shaped notch can be close to each other, and after nesting and fixing the shell interior 11 and the shell exterior 12 so that the thermal insulation layer 13 is maintained between the shell interior 11 and the shell exterior 12, the two edges of the thermal insulation layer 13 forming the "V"-shaped notch can fit together. In this way, the thermal insulation layer 13 can be evenly arranged around and at the bottom of the retaining space 101 of the thermal insulation shell 10, so that the thermal insulation shell 10 can provide a consistent thermal insulation effect around and at the bottom of the food container 20.

[0054] In another example of the tableware with the heat-insulating layer, the shell interior 11 and the shell exterior 12 of the heat-insulating outer shell 10 are not prefabricated parts, but allow the shell interior 11 to be integrally formed on the inner side of the heat-insulating layer 13 and allow the shell exterior 12 to be integrally formed on the outer side of the heat-insulating layer 13. Specifically, first, the heat-insulating layer 13 is provided; second, the heat-insulating layer 13 is set in a molding die; third, molding material is injected into the molding die, and the molding material is allowed to wrap the heat-insulating layer 13; fourth, after the molding material is solidified and the molding die is demolded, the molding material forms the shell interior 11 integrally formed on the inner side of the heat-insulating layer 13 and the shell exterior 12 integrally formed on the outer side of the heat-insulating layer 13.

[0055] In another example of the tableware with insulation layer, the insulation layer 13 of the insulation shell 10 is not a prefabricated part, but allows the insulation layer 13 to be integrally formed on at least one of the inner wall of the shell interior 11 and the inner wall of the shell exterior 12. Figure 5A In the specific example of the tableware with the heat-insulating layer shown, first, the heat-insulating layer 13 is integrally formed on the inner wall of the shell interior 11 by attaching the heat-insulating material to the inner wall of the shell interior 11; second, the shell interior 11 is nested in the concave cavity of the shell exterior 12 so that the heat-insulating layer 13 is maintained between the shell interior 11 and the shell exterior 12; third, the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 are fixedly connected so that the shell interior 11, the heat-insulating layer 13 and the shell exterior 12 are integrated. Figure 5B In the specific example of the tableware with the thermal insulation layer shown, first, the thermal insulation layer 13 is integrally formed on the inner wall of the shell exterior 12 by attaching the thermal insulation material to the inner wall of the shell exterior 12; second, the shell interior 11 is nested in the concave cavity of the shell exterior 12 so that the thermal insulation layer 13 is maintained between the shell interior 11 and the shell exterior 12; third, the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 are fixedly connected so that the shell interior 11, the thermal insulation layer 13 and the shell exterior 12 are integrated. Optionally, in other examples of the tableware with the thermal insulation layer, first, one of the thermal insulation layers 13 is integrally formed on the inner wall of the shell interior 11 by attaching the thermal insulation material to the inner wall of the shell interior 11, and another thermal insulation layer 13 is integrally formed on the inner wall of the shell exterior 12 by attaching the thermal insulation material to the inner wall of the shell exterior 12; secondly, the shell interior 11 is nested in the concave cavity of the shell exterior 12 so that the thermal insulation layer 13 is maintained between the shell interior 11 and the shell exterior 12; thirdly, the top edge position of the shell interior 11 and the top edge position of the shell exterior 12 are fixedly connected so that the shell interior 11, the thermal insulation layer 13 and the shell exterior 12 are integrated.

[0056] With reference to the accompanying drawings of the present invention Figures 6 to 9 According to another preferred embodiment of the present invention, a tableware with a heat-insulating layer is disclosed and described in the following description, and the attached Figures 1 to 4 The tableware with heat-insulating layer shown in the drawings is different in that Figures 6 to 9In the specific example of the tableware with insulation layer shown, the protective ring 30 has at least one insertion port 31, and the protective ring 30 is installed on the shell exterior 12 of the insulation shell 10 to form a disinfection space 40 between the protective ring 30 and the insulation shell 10, and the insertion port 31 of the protective ring 30 connects the disinfection space 40 with the external environment. The tableware with insulation layer further includes a disinfection cover 50, and the disinfection cover 50 has a group of ultraviolet lamps 51, wherein the disinfection cover 50 can be installed on the protective ring 30 in a manner that the ultraviolet lamps 51 of the disinfection cover 50 face the disinfection space 40, so that the ultraviolet lamps 51 of the disinfection cover 50 can radiate ultraviolet rays into the disinfection space 40. The end of a food-taking piece 100 can be inserted into the disinfection space 40 through the insertion port 31 of the protective ring 30, so that the end of the food-taking piece 100 held in the disinfection space 40 can be disinfected in the disinfection space 40.

[0057] It is worth mentioning that the type of the food taking tool 100 is not limited in the present invention. For example, the food taking tool 100 can be but is not limited to a spoon, a fork, chopsticks, etc.

[0058] The tableware with the insulation layer has a dining state and a disinfection state, and the tableware with the insulation layer can switch between the dining state and the disinfection state. When the tableware with the insulation layer is in the dining state, the insertion port 31 of the protective ring 30 can be blocked by the shell exterior 12 of the insulation shell 10, and at this time, the protective ring 30 can be configured to lock the insulation shell 10 and the food container 20. Accordingly, when the tableware with the insulation layer is in the disinfection state, the disinfection space 40 is formed between the protective ring 30 and the insulation shell 10, so that the insertion port 31 of the protective ring 30 connects the disinfection space 40 with the external environment, so that one end of the food taking piece 100 is allowed to be inserted into the disinfection space 40 from the insertion port 31 of the protective ring 30.

[0059] Furthermore, the protective ring 30 includes a ring body 32 and at least one deformable protective body 33 installed on the ring body 32, and the insertion port 31 is formed on the protective body 33, wherein the ring body 32 of the protective ring 30 can be installed in a sleeve-like manner on the shell exterior 12 of the thermal insulation shell 10 to keep the protective body 33 on the side of the thermal insulation shell 10. In the tableware with the heat-insulating layer of the present invention, the ring body 32 of the protective ring 30 is hard to avoid deformation of the ring body 32, so that the ring body 32 of the protective ring 30 can be reliably installed on the heat-insulating shell 10, and at the same time, the protective body 33 of the protective ring 30 is flexible to allow the protective body 33 to deform, so that the opening size and shape of the insertion port 31 of the protective ring 30 can be deformed based on the size and shape of the food-taking piece 100. In this way, after one end of the food-taking piece 100 is inserted into the disinfection space 40 from the insertion port 31 of the protective ring 30, the protective body 33 can wrap the part of the food-taking piece 100 held in the insertion port 31 to avoid a gap between the protective body 33 and the food-taking piece 100 as much as possible, so that when the part of the food-taking piece 100 held in the disinfection space 40 is disinfected by ultraviolet rays, the leakage of ultraviolet rays from between the protective body 33 and the food-taking piece 100 can be reduced.

[0060] Preferably, the protective body 33 of the protective ring 30 is made of silicone material, such as food-grade silicone, so that the protective body 33 of the protective ring 30 is flexible and allows the protective body 33 to be deformed, so that when one end of the feeding piece 100 is inserted into the disinfection space 40 from the insertion port 31 of the protective ring 30, the protective body 33 can automatically wrap the part of the feeding piece 100 held in the insertion port 31, and the size and shape of the insertion port 31 formed by the protective body 33 can adapt to the size and shape of the feeding piece 100 held in the insertion port 31 to obtain a plug-and-close effect.

[0061] In a preferred example of the tableware with a heat-insulating layer of the present invention, the protective body 33 of the protective ring 30 is detachably mounted on the ring body 32, so that the protective body 33 is easily replaced. Specifically, the ring body 32 has a mounting portion 321, wherein the mounting portion 321 communicates with the inner wall and the outer wall of the ring body 32, and the protective body 33 is detachably mounted on the mounting portion 321 of the ring body 32.

[0062] In other examples of the tableware with a heat-insulating layer of the present invention, the protective body 33 of the protective ring 30 is integrally formed with the ring body 32. Specifically, in the process of manufacturing the protective ring 30, first, the ring body 32 having the mounting portion 321 is provided, and secondly, the protective body 33 is integrally formed with the mounting portion 321 of the ring body 32 based on a secondary injection molding process, so that the protective body 33 is integrally formed with the ring body 32.

[0063] The protective body 33 of the protective ring 30 has at least one first-direction through slot 331 and at least one second-direction through slot 332, the first-direction through slot 331 and the second-direction through slot 332 intersect to form the insertion port 31 of the protective ring 30, and in this way, the size and shape of the insertion port 31 of the protective ring 30 can be deformed based on the size and shape of the food-taking piece 100, that is, the size and shape of the insertion port 31 of the protective ring 30 can adapt to the size and shape of the portion of the food-taking piece 100 that is held at the insertion port 31 of the protective ring 30. Preferably, the first-direction through slot 331 and the second-direction through slot 332 of the protective body 33 of the protective ring 30 are perpendicular to each other.

[0064] The protection body 33 of the protection ring 30 has a first-direction through groove 331 and a plurality of second-direction through grooves 332, wherein the first-direction through groove 331 extends along the circumferential direction of the protection ring 30, and each second-direction through groove 332 extends along the height direction of the protection ring 30, and each second-direction through groove 332 is perpendicular to the first-direction through groove 331, so that the first-direction through grooves 331 and the second-direction through grooves 332 of the protection ring 30 are allowed to have a plurality of intersection positions 333, and in this way, the tableware with the heat-insulating layer allows a plurality of the food-taking pieces 100 to be simultaneously held in the insertion port 31 of the protection ring 30, and the protection body 33 of the protection ring 30 can automatically wrap the portion of each food-taking piece 100 held in the insertion port 31. Preferably, the middle portions of the first-direction through groove 331 and each second-direction through groove 332 intersect to form the intersection position 333.

[0065] The outer wall of the shell exterior 12 of the heat-insulating outer shell 10 is provided with a threaded structure, and the inner wall of the ring body 32 of the protective ring 30 is provided with a threaded structure, and the threaded structure of the shell exterior 12 of the heat-insulating outer shell 10 and the threaded structure of the ring body 32 cooperate to allow the ring body 32 to be installed in a sleeve-like manner on the shell exterior 12 in a manner that the ring body 32 is screwed to the shell exterior 12 of the heat-insulating outer shell 10. In the tableware with a heat-insulating layer of the present invention, the tableware with a heat-insulating layer is allowed to switch between the dining state and the disinfection state by screwing the ring body 32 of the protective ring 30 to different positions of the shell exterior 12, so that the tableware with a heat-insulating layer is convenient to use.

[0066] Specifically, in the tableware with a thermal insulation layer of the present invention, when the threaded structure located at the bottom of the ring body 32 of the protective ring 30 and the threaded structure located at the bottom of the shell exterior 12 are screwed together, the tableware with a thermal insulation layer is in the dining state, at which time the insertion port 31 of the protective ring 30 is blocked by the outer wall of the shell exterior 12, and the protective ring 30 locks the thermal insulation outer shell 10 and the food container 20; when the threaded structure located at the bottom of the ring body 32 of the protective ring 30 and the threaded structure located at the top of the shell exterior 12 are screwed together by allowing the protective ring 30 and the shell exterior 12 to rotate relative to each other, the tableware with a thermal insulation layer is in the disinfection state, at which time the disinfection space 40 is formed between the protective ring 30 and the thermal insulation outer shell 10, and the insertion port 31 of the protective ring 30 is connected to the disinfection space 40. It can be understood that the spatial height of the disinfection space 40 of the tableware with the insulation layer is greater than the spatial height of the holding space 101 of the insulation shell 10, that is, when the tableware with the insulation layer is in the disinfection state, the holding space 101 defined by the insulation shell 10 and the space defined by the protective ring 30 form the disinfection space 40, so that the height of the disinfection space 40 is greater than the height of the holding space 101 of the insulation shell 10, so that when one end of the food taking piece 100 is inserted into the disinfection space 40 from the insertion port 31 of the protective ring 30, more parts of the food taking piece 100 are located in the disinfection space 40, which is conducive to disinfecting the parts of the food taking piece 100 that may contact food.

[0067] Attached Fig. 9 The tableware with the heat-insulating layer shown is applied to the use process during disinfection.

[0068] One end of the feeding piece 100 is allowed to be inserted into the disinfection space 40 from the insertion port 31 of the protective ring 30. During this process, the size and shape of the insertion port 31 of the protective ring 30 are deformed based on the size and shape of the feeding piece 100, that is, the size and shape of the insertion port 31 of the protective ring 30 can be automatically deformed to adapt to the part of the feeding piece 100 held at the insertion port 31, so that the protective body 33 of the protective ring 30 can wrap the part of the feeding piece 100 held at the insertion port 31. The disinfection cover 50 is installed on the high end edge of the protective ring 30 in such a manner that the ultraviolet lamp 51 of the disinfection cover 50 faces the disinfection space 40. When the ultraviolet lamp 51 of the disinfection cover 50 is in working state, the ultraviolet lamp 51 can generate ultraviolet rays and radiate to the disinfection space 40. Since the protective body 33 of the protective ring 30 wraps the portion of the food taking piece 100 held at the insertion port 31, the tableware with the heat-insulating layer can reduce the leakage of ultraviolet rays between the protective ring 30 and the food taking piece 100.
