Description

Technical Field

[0001] This patent relates to the food packaging industry, specifically to a liquid spraying device with a baffle. Background Technology

[0002] Liquid spraying devices, primarily used in food pressurized containers (such as aerosol cream cans, carbonated beverage cans, portable condiment spray cans, etc.), are sealed containers that use internal pressure to spray food contents in a mist, foam, or liquid form. Commonly found in restaurants, bars, and cafes, users need to prepare the food first, such as putting cream into the bottle, and then filling it with pressurized gas. The cream can then be sprayed out directly during use. Some devices pre-mix the food and pressurized gas in the bottle for easier use. However, during use, accidental collisions may cause the food to spray out. Utility Model Content

[0003] To address the above issues, this patent proposes a liquid spraying device with a baffle to prevent food from being accidentally sprayed out.

[0005] A liquid spraying device with a baffle includes a spray can (1) and a spray can housing (2). The spray can (1) is provided with a spray can valve (3). The top of the spray can housing (2) is an open end, and the bottom is provided with a spray port (5). The spray can is placed upside down in the spray can housing (2), and the bottom of the spray can (1) is higher than the top opening of the spray can housing (2). A baffle (4) is provided below the spray can housing (2).

[0006] Furthermore, the spray can housing (2) has a step (6).

[0007] Furthermore, the baffle (3) is provided with anti-slip texture.

[0008] Furthermore, the baffle (4) is in the shape of a plug.

[0009] Furthermore, the injection port (5) includes a through hole (51) and an annular protrusion (52).

[0010] Beneficial effects

[0020] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Liquid spraying devices can be used in food pressure cans, such as aerosol cream cans, carbonated beverage cans, and portable seasoning spray cans. A food pressure can is a sealed container that uses internal pressure to spray food contents in a mist, foam, or liquid form. Food and other pressurized materials are pre-filled into the can to form a pressurized food can. The food is usually a liquid, such as cream or espresso. The can includes a body, a nozzle, a valve stem, and a spring. The spring provides the valve stem with a restoring force, automatically closing the passage when the pressure is released. When pressed: the valve stem moves down, compressing the spring, connecting the nozzle to the internal passage of the container, and the food is sprayed out. After production, during transportation, accidental impact or squeezing of the nozzle may cause the liquid food in the can to spray out.

[0022] like Figure 1 , Figure 2 The spray can 1 of this patent is cylindrical and can be a food pressure can pre-filled with food such as cream or coffee liquid; the spray can 1 has a valve 3 and an end face 6; the spray can 1 is provided with a spray can valve 3; by pressing the valve, the spray can 1 can spray out liquid food such as cream or coffee liquid.

[0023] The spray can 1 is placed upside down inside the spray can housing 2; the housing 2 is also cylindrical, open at the top and with a spray nozzle at the bottom. The spray can 1 is placed into the housing 2 with the nozzle facing downwards; the bottom of the housing 2 has a spray nozzle 5. Pressing down on the spray can 1 causes it to move relative to the housing 2, at which point the valve 3 opens under the pressure, spraying out liquid food.

[0024] The spray can 1 is placed upside down in the spray can housing 2. The food liquid in the can may be sprayed out due to accidental collision and squeezing of the nozzle.

[0025] The length of the spray can housing 2 is shorter than that of the spray can 1, so that when the user holds the housing 2, he can press the spray can 1 with his fingers and the valve 3 will open under pressure.

[0026] The outer casing 2 is a cylindrical body with an opening at the top. The top opening is not horizontal; part of its surface is horizontal, while the other part is lower, forming a sloping or curved surface with a notch. When the food pressure can is placed inside the outer casing 2, the length of the can is greater than the edge of the outer casing, exposing part of the spray can 1. This allows the user to press down on the food pressure can, causing it to move relative to the outer casing and pressurize the nozzle to spray out the food contents. Furthermore, when the upper edge of the outer casing 2 is designed as a concave slope, more of the spray can 1 surface is exposed. This makes it easier to press down on the spray can 1 with one hand when holding the casing 2, with the index finger touching one side of the casing and the thumb against the concave area. This design also facilitates one-handed removal of the spray can 1.

[0027] like Figures 3-8 To prevent the spray can 1 from being accidentally pressed, especially by collisions during transportation, a baffle 4 is installed at the lower end of the spray can housing 2;

[0028] An opening is provided on the side of the housing 2, the position of which corresponds to the position of the step 6 after the spray can 1 is inserted. The shape of the opening is set according to the shape of the baffle, for example, as shown. Figure 4 If the baffle is sheet-shaped, the opening should be such that the sheet-shaped baffle can be inserted into the slit. After inserting the baffle 4, press it against the end face of the step 6 of the spray can 1 to avoid collision and squeezing. When using, simply remove the baffle 4.

[0029] like Figure 4 The diagram shows the shape of a baffle 4, wherein the front end 41 of the baffle is inserted into the housing, and the rear end 42 remains outside the housing, facilitating the user to remove the baffle. The baffle has anti-slip texture.

[0030] The baffle 4 can be made of plastic. The plastic sheet has a certain elasticity and is inserted into the housing 2. It is fixed to the housing and prevented from falling off by its own elasticity.

[0031] like Figure 5This shows the shape of the baffle 4 inserted into the outer shell from another angle.

[0032] It should be emphasized that the baffle 4 in this patent serves to prevent the spray can from moving downwards, and the baffle adopts the following... Figure 4 The shape of the baffle can also be other shapes, such as a plug shape, a square plug, which better supports the step surface 6. It can also be made of plastic, making it more stable after insertion and less prone to accidental contact. In this case, the opening of the shell 2 can be square, suitable for inserting the plug. The patented baffle includes this plug-shaped blocking structure.

[0033] like Figure 6 , Figure 7 , Figure 8 The rear end 42 of the baffle 4 is relatively long and easily bumped. To further prevent the rear end 42 of the baffle 4 from being bumped, the baffle 4 can be made into a plug shape, so that the part of its rear end 42 protruding outside the housing 2 does not extend too far outward, but fits snugly against the housing 2. The rear end 42 can be made as follows: Figure 6 It can be shaped like a gold ingot or a cloud, or other shapes. Similarly, after insertion, it should be pressed against the end face 6 of the spray can 1.

[0034] The baffle 4 serves to prevent food from spraying out due to accidental bumps or knocks.

[0035] Figure 9 The structure of the spray nozzle is further shown. The spray can 1 is equipped with a spray can valve 3, and the front end is a nozzle 31. The nozzle 31 is inserted into the annular protrusion 52, which can also be called an annular flange. It can position the nozzle 31. After the valve is pressed to open, the liquid is sprayed out from the nozzle 31 and then sprayed out from the through hole 51.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of this patent, and not to limit them; although this patent has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this patent.
