Description

Technical Field

[0001] This utility model relates to a quantitative grain packaging bag. Background Technology

[0002] Pet food packaging bags are bags specifically designed for packaging pet food. These bags not only protect the pet food from moisture, contamination, insects, and oxidation, but also ensure its quality and safety. However, existing pet food packaging bags only preserve the pet food; they cannot dispense measured portions. Before feeding, the pet food must be weighed manually using a scale or similar tool, which is cumbersome. If the pet food packaging bags were designed to be dispensed in fixed quantities, allowing for easy emptying of the dispensed portions, the convenience of operation would be greatly improved. Therefore, this invention was developed. Utility Model Content

[0003] This utility model addresses the problems existing in the prior art by providing a quantitative grain packaging bag.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quantitative grain packaging bag, comprising a bag body with a discharge port at the top, the interior of the bag body being divided into an upper grain layer and a lower grain layer by a partition, the upper grain layer being connected to the discharge port; a vertical perforation is provided in the middle of the partition, and a separating film for blocking the upper and lower grain layers is provided in the vertical perforation; a knob cover for sealing the discharge port is threadedly connected to the discharge port, and a conveying pipe is coaxially inserted through the middle of the knob cover, the conveying pipe passing through the discharge port and extending into the upper grain layer and close to the middle of the partition; when the knob cover is rotated downwards, it drives the conveying pipe downwards and punctures the separating film, so that the lower grain layer is connected to the conveying pipe.

[0005] Furthermore, the discharge port has a vertically upward extending cylindrical structure, and the outer peripheral side of the discharge port is provided with external threads; the knob cover is sleeved on the outside of the discharge port, and the inner peripheral side of the knob cover is provided with internal threads for cooperating with the external threads.

[0006] Furthermore, a vertically penetrating fixed through hole is provided at the top center of the knob cover, and the upper end of the feed tube is fixedly connected to the inner wall of the fixed through hole, with the top surface of the feed tube flush with the top surface of the knob cover.

[0007] Furthermore, an elastic sealing block is provided between the inner top surface of the knob cover and the top surface of the discharge port. The elastic sealing block is arranged around the outside of the conveying pipe. When the knob cover is rotated downwards, the knob cover presses the elastic sealing block onto the top of the discharge port to block the discharge port.

[0008] Furthermore, the bag body is made of BOPE or CPE.

[0009] Furthermore, the partition is arranged horizontally.

[0010] Furthermore, the partition is made of plastic.

[0011] Compared with the prior art, the present invention has the following advantages: The present invention is reasonably designed. By setting up an upper food layer and a lower food layer with independent discharge inside the bag, the upper food layer and the lower food layer are respectively quantitatively filled with pet food. When using it, you only need to pour out the quantitatively packaged pet food, which effectively improves the convenience of operation and allows pets to eat healthily. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1-7 As shown, this utility model discloses a quantitative pet food packaging bag, comprising a bag body 1 with a discharge port 2 at the top center. The interior of the bag body 1 is divided into an upper food layer 4 and a lower food layer 5 by a horizontally arranged partition 3. The upper food layer 4 and the lower food layer 5 are used to hold a predetermined amount of pet food respectively. The upper food layer 4 is connected to the discharge port 2, and the pet food in the upper food layer is poured out through the discharge port. The partition 3 has a vertical perforation 6 in the middle, and a separating film 7 is arranged in the vertical perforation 6. The separating film 7 is used to separate the upper food layer 4 and the lower food layer 5. The separating film not only separates the layers but also has a moisture-proof and waterproof function, effectively separating the two layers of quantitative pet food. The outlet 2 is threadedly connected to a knob cover 8 for sealing the outlet 2. A feed tube 9 is coaxially inserted through the middle of the knob cover 8. When the knob cover 8 is rotated upward, the feed tube 9 moves upward because it is fixedly connected to the knob cover 8. Conversely, when the knob cover is rotated downward, the knob cover 8 moves the feed tube 9 downward. The feed tube 9 passes through the outlet 2 and extends into the upper food layer 4 and is close to the middle of the partition 3. When the knob cover 8 is rotated downward, the feed tube 9 moves downward and punctures the dispensing film 7, so that the lower food layer 5 is connected to the feed tube 9. At this time, the pet food in the lower food layer 5 can be poured out through the feed tube 9.

[0022] In practical use: The upper and lower food layers are each filled with a predetermined amount of pet food. To use, rotate the knob upwards, causing the feed tube to move upwards. Once the knob separates from the outlet, the pet food in the upper food layer can be poured out through the outlet. Then, reinsert the feed tube into the upper food layer and thread the knob back onto the outlet, ensuring the feed tube does not contact the dispensing film. To pour out the pet food from the lower food layer, continue rotating the knob downwards. The knob moves the feed tube downwards, puncturing the dispensing film, allowing the pet food in the lower food layer to pour out through the feed tube. By having independently dispensed upper and lower food layers inside the bag, each containing a predetermined amount of pet food, users simply need to pour out the pre-portioned pet food. This significantly improves ease of use, ensuring pets eat healthily and preventing malnutrition due to insufficient food intake or obesity due to improper diet.

[0023] In this embodiment, the discharge port 2 is a cylindrical structure extending vertically upward, and the outer peripheral side of the discharge port 2 is provided with external threads; the knob cover 8 is a cylindrical structure, the knob cover 8 is sleeved on the outside of the discharge port 2, and the inner peripheral side of the knob cover 8 is provided with internal threads for cooperating with the external threads.

[0024] In this embodiment, a vertically penetrating fixed through hole 10 is formed at the top center of the knob cover 8. The upper end of the conveying pipe 9 is fixedly connected to the inner wall of the fixed through hole 10, and the top surface of the conveying pipe 9 is flush with the top surface of the knob cover 8. When the knob cover is threadedly connected to the outlet, the outlet is located between the peripheral wall of the knob cover and the conveying pipe. At this time, the top opening of the outlet is not connected to the outside, thus sealing the outlet.

[0025] In this embodiment, an elastic sealing block 11 is provided between the inner top surface of the knob cover 8 and the top surface of the discharge port. The elastic sealing block 11 is arranged around the outside of the conveying pipe 9. When the knob cover 8 is rotated downwards, the knob cover 8 presses the elastic sealing block 11 onto the top of the discharge port 2 to seal the discharge port. By setting the elastic sealing block to seal the discharge port, the sealing effect of the discharge port is improved.

[0026] In this embodiment, the bag body 1 is made of BOPE or CPE, which makes the bag heat-resistant, has good barrier properties, and prevents the contents from deteriorating. Furthermore, the single material makes recycling and reuse after the packaging bag is discarded possible, greatly increasing its recycling value. Traditional plastic bags are often made of multiple composite materials, which are difficult and costly to recycle, resulting in low recycling value.

[0027] In this embodiment, the partition 3 is made of plastic.

[0028] It should be noted that in actual use, the top and bottom food layers should be filled with two standard adult pet food portions (for example, an average adult cat weighing less than 3 kg should eat 30-50 grams per day, and an adult cat weighing between 3 kg and 5 kg should eat 75-100 grams per day).

[0029] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0030] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this utility model to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.

[0031] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
