[0002] Barrels are usually used to hold liquid or viscous paste in industrial production or daily life, in order to avoid the material adhering to the inner wall of the barrel, an inner liner bag, such as a common plastic bag, is usually set in the barrel to isolate the material and the inner wall of the barrel. However, after the inner liner bag is put in, air is left between the inner liner bag and the inner wall of the barrel, which prevents the inner liner bag from adhering to the inner wall of the barrel.

[0003] Therefore, a packaging barrel is produced on the market, which has a structure as shown in Figure 1 、 2 includes a barrel body 1, a barrel bottom 2 and a barrel cover 3. The barrel cover 3 is detachably arranged on the barrel body 1, and the barrel bottom 2 is fixedly arranged at the bottom of the barrel body 1. An air passage 4 is formed in the barrel bottom 2. When in use, the inner liner bag is set in the barrel body 1, and the air passage 4 can help the air between the inner liner bag and the inner wall of the barrel body 1 to flow out, so that the air pressure between the inner wall of the barrel body 1 and the inner liner bag is balanced with the external air pressure, thereby ensuring that the inner liner bag can adhere to the inner wall of the barrel body 1.

[0004] However, the air passage 4 in the above-mentioned patent is located at the center of the barrel bottom 2. If liquid or viscous paste is stored, the material will extrude the inner liner bag and make it protrude from the air passage 4 due to the flowability of the liquid or viscous paste, which causes inconvenience for storing the liquid or viscous paste.

[0024] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present application, and do not constitute a limitation on the present application.

[0025] As Figures 3-6 shown, the present embodiment includes barrel body 1, barrel bottom 2 and barrel cover 3, barrel bottom 2 is fixedly arranged at the bottom end of barrel body 1, and barrel cover 3 is detachably arranged at the barrel mouth. The detachable connection here is as follows: as Figure 3 shown, a bump 5 is fixedly arranged at the barrel mouth, and a card slot 6 is arranged at the position corresponding to the bump 5 on the barrel cover 3. By pressing the barrel cover 3 downward, the bump 5 is clamped in the card slot 6, thereby realizing the fixation of the barrel cover 3 and the barrel body 1. Of course, the barrel cover 3 and the barrel mouth can also be replaced by any other detachable connection in the prior art, such as threaded connection. A handle 7 is rotatably arranged on the barrel body 1, and an arc-shaped protrusion 8 protruding towards the hand is arranged at the position where the handle 7 contacts the hand. The arc-shaped protrusion 8 can better fit the shape of the hand, and it is more comfortable to hold and carry. The barrel body 1, the barrel bottom 2, the barrel cover 3 and the handle 7 are all made of hard plastic, which is more environmentally friendly. This part is prior art.

[0026] The main improvement of the present embodiment is in the barrel bottom 2. Specifically, as Figures 4-6 shown, a through hole 9 is arranged on the barrel bottom 2, which is circular in the present embodiment. A brace plate 10 is arranged inside the barrel bottom 2 corresponding to the position of the through hole 9. Here, the inside of the barrel bottom 2 refers to the side of the barrel bottom 2 facing the barrel cover 3. A supporting block 11 is arranged between the brace plate 10 and the barrel bottom 2. The supporting block 11 is fixedly connected with the brace plate 10 and the barrel bottom 2. The supporting block 11 is used to support and fix the brace plate 10, so as to separate the brace plate 10 from the barrel bottom 2, thereby forming a gap 12 between the brace plate 10, the supporting block 11 and the barrel bottom 2, which facilitates air circulation, as Figure 6 shown. The gap 12 can not only ensure that the inner liner bag can fit the inner wall of the barrel body 1 after being put in, but also ensure that the material and the inner liner bag can smoothly separate from the inner wall of the barrel body 1 and pour out of the barrel mouth when pouring the material.

[0027] As Figure 5As shown, four support blocks 11 are arranged in the circumferential direction of the through hole 9 in the embodiment. Of course, the number of support blocks 11 can also be two, three or other numbers; the through hole 9 in the embodiment can also be rectangular or other shapes, and the support blocks 11 are arranged along the edges of the through hole 9 to ensure that the gap 12 is formed between the support plate 10, the support blocks 11 and the barrel bottom 2. The support blocks 11 and the support plate 10 in the embodiment are made of hard plastic, which is more environmentally friendly.

[0028] Further, the size of the support plate 10 is adapted to the size of the through hole 9, which means that the size of the support plate 10 is greater than or equal to the size of the through hole 9. The support plate 10 in the embodiment is also circular, and its diameter is equal to the diameter of the through hole 9, in other words, as shown in the enlarged view of the through hole 9 in the barrel bottom 2, the support plate 10 is arranged in the through hole 9. Figure 5 As shown, there is no hole in the barrel bottom 2 from the bottom view, of course, if the size of the support plate 10 is greater than the size of the through hole 9, there is also no hole in the barrel bottom 2 from the bottom view. This structure can not only realize air circulation and ensure that the inner liner bag is more closely attached to the inner wall of the barrel body 1, but also prevent the material from extruding the inner liner bag to stretch out of the barrel bottom 2 in the vertical direction. Here, the size of the support plate 10 can also be slightly smaller than the size of the through hole 9. This design mainly considers the production process. If the one-piece molding process is adopted, the size of the support plate 10 in the finished product is slightly smaller (or very close) to the size of the through hole 9, which can also prevent the material from extruding the inner liner bag to stretch out of the barrel bottom 2. If the one-piece molding process is not adopted, the size of the support plate 10 can be set to be greater than or equal to the size of the through hole 9.

[0029] It should be noted that the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
