Description

Technical Field

[0001] This utility model relates to the field of heat preservation device technology, and in particular to a novel heat preservation barrel. Background Technology

[0002] The high quality of insulated food containers is receiving increasing attention, with higher requirements for cleanliness, hygiene, safety, and portability. To facilitate the transport of insulated food, these containers are typically made of a single stainless steel material. However, this results in a shorter temperature maintenance time, makes the containers susceptible to impact damage, and poses safety hazards during transport. Additionally, insulated containers made entirely of plastic are prone to cracking over time.

[0003] A search revealed prior art CN202201331 U, which describes a thermos, particularly for keeping food, boiling water, and soup warm. This thermos includes a lid, a body, and an inner liner. The inner liner is placed inside the body, and the lid covers the body. The inner liner is made of stainless steel. The thermos also includes a locking mechanism; one side of the lid is fastened to the body via the locking mechanism. The body is formed using a rotational molding process, and the body and inner liner are connected by polyurethane foam filling. This utility model adopts an embedded structure, embedding the stainless steel inner liner within the body to avoid direct contact between the plastic and the food, thus ensuring food safety. Furthermore, the polyurethane foam filling enhances the thermos's robustness and insulation effect, extending its service life.

[0004] However, the above-mentioned insulated buckets have the following problems when in use: the insulated buckets are moved by the handles that are symmetrically arranged on the lid, but the handle structure is difficult to repair afterward, so a new whole lid needs to be replaced, which significantly increases the cost of use. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of insulated bucket, which aims to solve the problem that the moving handle of most existing insulated buckets is fixed on the lid, and it is difficult to repair after the handle structure is damaged, so it is necessary to replace the whole lid, which significantly increases the cost of use.

[0006] To achieve the above objectives, this utility model provides a novel insulated bucket, including an insulated bucket body, which is composed of an EPP outer shell, a stainless steel inner liner, and a bucket lid. The outer surface of the stainless steel inner liner and the EPP outer shell is sprayed with an insulating coating and integrally formed with the EPP outer shell. The bucket lid is screwed onto the outside of the top opening of the stainless steel inner liner.

[0007] It also includes the lifting mechanism;

[0008] The lifting mechanism includes a hexagonal nut, an abutment ring, a retaining spring for the hole, a fixing seat, a fixing screw, a lifting rod, and a limiting device. The hexagonal nut is disposed in the non-penetrating hexagonal cavity of the EPP shell and is located inside the limiting part. The limiting part is integrally formed with the EPP shell and is symmetrically arranged, and is slidably connected to the abutment ring. The abutment ring abuts against the hexagonal nut and is limited by the retaining spring for the hole installed inside the limiting part. The fixing seat is installed on the EPP shell through the fixing screw and the hexagonal nut. The lifting rod is installed on the fixing seat through the limiting device and can rotate simultaneously, and is provided with an anti-slip part.

[0009] The barrel lid has a U-shaped stainless steel component with an opening facing downwards inside, and both sides of the U-shaped stainless steel component are coated with a heat-insulating coating.

[0010] The limiting device includes an inner retaining spring and an outer retaining spring. The inner retaining spring is detachably connected to the lifting rod and is located inside the cavity of the fixed base. The outer retaining spring is detachably connected to the lifting rod and is located on the side of the lifting rod away from the inner retaining spring.

[0011] The inner snap ring and the outer snap ring are respectively shaft snap rings.

[0012] The top of the bucket lid is provided with a limiting groove that does not penetrate the inner cavity.

[0013] This utility model discloses a novel insulated bucket. When transporting food, the lid is first unscrewed, the food is placed in the stainless steel inner liner, and the lid is screwed back on. The bucket can then be moved using a lifting rod. In subsequent use, removing the limiting device allows the lifting rod to be separated from the fixed base, removing the fixing screw allows the fixed base to be separated from the EPP outer shell, removing the retaining ring allows the abutment ring to be separated from the limiting part, and finally, the hexagonal nut can be directly removed. The corresponding parts of the lifting mechanism in this application can be removed and replaced individually, thus eliminating the need to replace the EPP outer shell or the entire bucket lid, which helps reduce usage costs. This also solves the problem that the moving handles of most existing insulated buckets are fixed to the lid, and it is difficult to repair the handle structure after it is damaged, thus requiring the replacement of a new entire bucket lid, which significantly increases the usage cost.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] like Figures 1 to 5 As shown, where Figure 1 This is a schematic diagram of the overall structure of the new type of insulated bucket. Figure 2 This is a schematic diagram showing the overlapping state of the new type of insulated buckets. Figure 3 This is a cross-sectional view of the new type of insulated bucket. Figure 4 This is a structural diagram of the fixed base. Figure 5 This is a structural schematic diagram of the abutment ring. This utility model provides a novel insulated bucket: it includes an insulated bucket body 100 and a lifting mechanism. The insulated bucket body 100 consists of an EPP outer shell 101, a stainless steel inner liner 102, and a lid 103. The lifting mechanism includes a hexagonal nut 105, an abutment ring 106, a retaining spring 107, a fixing base 108, a fixing screw 109, a lifting rod 110, and a limiting device. The limiting device includes an inner retaining spring 112 and an outer retaining spring 113. This solution solves the problem that most existing insulated buckets have their handles fixed to the lid, making them difficult to repair after damage, requiring replacement of the entire lid and significantly increasing operating costs. Therefore, this solution can help reduce operating costs.

[0023] In this embodiment, the insulated container body 100 can be directly used for food storage.

[0024] The insulated container body 100 consists of an EPP outer shell 101, a stainless steel inner liner 102, and a lid 103. The outer surface of the stainless steel inner liner 102 and the EPP outer shell 101 is coated with an insulating coating 104 and integrally formed with the EPP outer shell 101. The lid 103 is screwed onto the outside of the top opening of the stainless steel inner liner 102. During processing, the insulating coating 104 is first sprayed onto the outer surface of the stainless steel inner liner 102, and then the EPP outer shell 101 is integrally formed onto the outside of the stainless steel inner liner 102 using a mold. The installation structure of the lid 103 and the stainless steel inner liner 102 is similar to the structure of the lid of an insulated cup in the prior art, and can be directly rotated for installation or removal.

[0025] The hexagonal nut 105 is disposed in the non-penetrating hexagonal cavity of the EPP housing 101 and located inside the limiting part 115. The limiting part 115 is integrally formed with the EPP housing 101 and is symmetrically arranged, and is slidably connected with the abutment ring 106. The abutment ring 106 abuts against the hexagonal nut 105 and is limited by the hole-type snap ring 107 installed inside the limiting part 115. The fixing seat 108 is installed on the EPP housing 101 through the fixing screw 109 and the hexagonal nut 105. The lifting rod 110 is installed on the fixing seat 108 through the limiting device and can rotate at the same time, and is provided with an anti-slip part 111. The EPP outer shell 101 has symmetrically arranged non-penetrating rectangular grooves. Within each rectangular groove, a symmetrically arranged ring-shaped limiting part 115 is provided. The center of each limiting part 115 has a hexagonal groove smaller than its inner cavity size. A hexagonal nut 105 is placed directly within this hexagonal groove. The inner hole of the abutment ring 106 is larger than the threaded hole size of the hexagonal nut 105, while its outer diameter matches the inner hole size of the limiting part 115. A retaining ring groove is provided on the limiting part 115 to facilitate the installation of a retaining ring 107, thereby fixing the abutment ring 106. The fixing base 108 is fixed to the EPP outer shell 101 via a T-shaped fixing screw 109 that engages with the hexagonal nut 105. The lifting rod 110 is used for moving the insulated container.

[0026] Secondly, the barrel lid 103 has a downward-facing U-shaped stainless steel component inside, with heat-insulating coating 104 applied to both sides of the U-shaped stainless steel component. The downward-facing U-shaped stainless steel component inside the barrel lid 103 provides structural reinforcement, and the outer surface of the downward-facing U-shaped stainless steel component is also coated with heat-insulating coating 104. Finally, a food-grade plastic material is integrally wrapped around the outside of the heat-insulating coating 104. The U-shaped stainless steel component enhances the strength of the barrel lid 103.

[0027] Then, the inner retaining spring 112 is detached from the lifting rod 110 and located inside the cavity of the fixing base 108; the outer retaining spring 113 is detached from the lifting rod 110 and located on the side of the lifting rod 110 away from the inner retaining spring 112. The mounting end of the lifting rod 110 passes through the through hole on the fixing base 108 and exposes two retaining slots, thus facilitating the installation of the inner retaining spring 112 and the outer retaining spring 113. After installation, the inner retaining spring 112 and the outer retaining spring 113 ensure that the end of the lifting rod 110 will not detach from the fixing base 108. The lifting rod 110 will not interfere with the bucket lid 103 when rotating to both sides.

[0028] Furthermore, the inner retaining ring 112 and the outer retaining ring 113 are respectively shaft retaining rings.

[0029] Finally, the top of the lid 103 is provided with a limiting groove 114 that does not penetrate the inner cavity. The limiting groove 114 is adapted to the bottom of the EPP shell 101 and facilitates the bottom of the EPP shell 101 to slide in. The limiting groove 114 facilitates the stacking of insulated buckets. At this time, the lifting rod 110 is not in the vertical center position, but in the edge position to avoid obstruction.

[0030] This invention addresses the problem that existing insulated containers often have their handles fixed to the lid, making them difficult to repair after damage and requiring replacement of the entire lid, thus significantly increasing operating costs. For food transport, the lid 103 is first unscrewed, the food is placed in the stainless steel inner liner 102, and then the lid 103 is screwed back on. The container can then be moved using the lifting rod 110. During subsequent use, removing the limiting device allows the lifting rod 110 to be separated from the fixing base 108, enabling individual replacement of the lifting rod 110. Removing the two fixing screws 109 allows the fixing base 108 to be separated from the EPP outer shell 101. Separation allows for the individual replacement of the fixed base 108. Removing the hole retaining spring 107 allows the abutment ring 106 to be separated from the limiting part 115, enabling the individual replacement of the abutment ring 106. Finally, the hexagonal nut 105 can be directly removed and replaced individually. The corresponding components of the lifting mechanism in this application can be removed and replaced separately, thus eliminating the need to replace the EPP shell 101 or the entire lid 103 later, which helps reduce usage costs. This also solves the problem that most existing insulated buckets have their moving handles fixed on the lid, making it difficult to repair the handle structure after it is damaged, thus requiring the replacement of a new entire lid and significantly increasing usage costs.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
