Description

Technical Field

[0001] The utility model relates to the technical field of bottles and cans, in particular to food packaging bottles and cans. Background Art

[0002] Food storage cans are becoming more and more commonly used in daily life, and are often used for coffee, high-end rice, tea and other foods. In order to better protect the food in the food storage cans, such as the coffee bean sealed can with a one-way exhaust function disclosed in Chinese Patent Authorization Announcement No. CN216128683U, a one-way valve is set on the food storage can to discharge the gas generated by the food in the can in time. However, the food storage cans currently on the market are generally cylindrical, and there is a problem of large can lid size, which makes it difficult to hold the can lid tightly, especially for those girls with small palms and strength, it is difficult to tighten and open the can lid. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides a food packaging bottle can, which solves the problem that the can lid of a cylindrical food storage can is large in size and difficult to open and tighten.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A food packaging bottle can comprises a can body, a can cover and a one-way valve. The can body comprises a can bottom, a can body, an inclined shoulder and a neck portion. The neck portion is threadedly matched with the can cover. The one-way valve is arranged at the can bottom. The diameter of the inclined shoulder gradually increases from top to bottom.

[0006] The one-way valve is arranged at the center of the bottom surface of the tank, and the tank bottom is U-shaped.

[0007] A vent hole is arranged in the circumference of the tank cover, and the vent hole is located above the threaded portion of the tank cover.

[0008] The top surface of the mouth and neck portion is provided with a curling edge, and one side of the curling edge is in contact with the outer wall of the mouth and neck portion.

[0009] The bottom surface of the can cover is provided with an elastic rubber layer for matching with the top surface of the curled edge.

[0010] The diameter ratio of the neck portion to the can body portion is 1:1.5-1:2.

[0011] The tank body is made of film-coated aluminum plate.

[0012] The beneficial effects of the utility model are:

[0013] The one-way valve is arranged at the bottom of the tank to ensure that the one-way valve is not easily clogged by dust. The inclined shoulder reduces the diameter of the neck, making it easier to tighten and open the tank lid. At the same time, the tank body is easy to hold and carry.

[0018] A can body 1, a can bottom 11, a can body 12, an oblique shoulder 13, a mouth neck 14, a can cover 2, a one-way valve 3, an elastic rubber layer 4, a vent hole 5, and a curled edge 6. DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0020] In the embodiment, Figure 1 , Figure 2 As shown, the food packaging bottle can comprises a can body 1, a can cover 2 and a one-way valve 3. The can body 1 comprises a can bottom 11, a can body 12, an oblique shoulder 13 and a neck 14. The neck 14 is threadedly matched with the can cover 2. The one-way valve 3 is arranged on the can bottom 11. The diameter of the oblique shoulder 13 gradually increases from top to bottom. The one-way valve 3 is arranged on the can bottom 11 to ensure that the one-way valve is not easily blocked by dust. The oblique shoulder 13 reduces the diameter of the neck 14, which is convenient for tightening and opening the can cover 2. At the same time, the can body 1 is easy to hold and carry.

[0021] In the embodiment, Figure 2 As shown, the one-way valve 3 is arranged at the center of the bottom surface of the tank bottom 11, and the tank bottom 11 is U-shaped. The one-way valve 3 is arranged in the center and the U-shaped tank bottom 11 allows a certain distance between the one-way valve 3 and the support surface, so that the one-way valve 3 can be easily exhausted; the tank bottom 11 and the tank body 12 are combined together by rolling, and the sealant of the tank bottom 11 is used to complete the sealing with the tank body 12.

[0022] In the embodiment, Figure 1 , Figure 4 As shown, the circumference of the can cover 2 is provided with a vent hole 5, and the vent hole 5 is located above the threaded portion of the can cover 2. When the one-way valve 3 is damaged or blocked and cannot be exhausted, when the pressure in the can body 1 reaches a certain value, the gas can be exhausted from the vent hole 5 to prevent the can from expanding; the vent hole 5 can also provide a certain friction force to facilitate the opening of the can cover 2.

[0023] In the embodiment, Figure 2 , Figure 3As shown, the top surface of the mouth and neck 13 is provided with a curling edge 6, and one side of the curling edge 6 is in contact with the outer wall of the mouth and neck 14. It is used to roll up the cut edge of the material to prevent consumers from being scratched when using it, while ensuring the beautiful shape of the can body.

[0024] In the embodiment, Figure 3 As shown, the bottom surface of the can cover 2 is provided with an elastic adhesive layer 4 for cooperating with the top surface of the curling edge 6. The elastic adhesive layer 4 ensures that the can body 1 and the can cover 2 can be sealed multiple times.

[0025] In the embodiment, Figure 1 , Figure 2 As shown, the diameter ratio of the neck portion 14 to the body portion 12 is 1:1.5-1:2. The diameter of the body portion 12 is between 45-80 mm, and the optimal diameter ratio of the neck portion 14 to the body portion 11 is 1:1.8, which is convenient for carrying and for putting food into the can body 1.

[0026] In the embodiment, the can body 1 is made of a film-coated aluminum plate. The film on the can body 1 is a food-grade plastic film, and the can body 1 is not easy to chemically react with food or contaminate its unique flavor, and is environmentally friendly and safe.

[0027] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
