Description

Technical Field

[0001] This utility model relates to the field of pet feeding equipment technology, and in particular to a pet wet food bag with an automatic sealing spout. Background Technology

[0002] Currently, pets are typically fed by their owners who place food into a dish, which the pet then eats. However, this method results in a limited variety of food components, failing to provide adequate nutrition for pets. With technological advancements, wet pet food in paste form has become more widely used (this type of food is usually packaged in a sturdy, non-toxic plastic bag, with a threaded, resealable cap on the dispensing tube at the top center of the bag). Pet paste wet food has the following advantages: (1) Paste wet food is usually easier for pets to digest and absorb, especially for older pets or pets with weak digestive systems. This form of food can reduce their digestive burden. (2) Because it is produced by professional manufacturers, the nutrients in paste wet food are usually more concentrated than those in ordinary food. It can quickly replenish the energy and nutrition needed by pets, and is especially suitable for pets with weak bodies. (3) Paste wet food usually has good palatability, and pets are more likely to accept and eat it. This is especially effective for picky eaters. (4) Paste wet food can be squeezed out and fed directly, which is very convenient and especially suitable for busy pet owners. (5) When pets are recovering from serious illness, have weak constitutions, are nursing, or are old, paste wet food can be used as a means of quickly replenishing nutrition to help pets quickly recover their strength or enhance their immunity. (6) High-quality paste wet food usually contains a variety of nutrients, such as amino acids, lecithin, cod liver oil, complex vitamins and minerals. These ingredients help maintain the overall health of pets.

[0003] While existing wet pet food in paste form has many advantages, its packaging bags still have some technical drawbacks due to structural limitations. Specifically, each time a user opens the dispensing tube of the wet food bag and squeezes out the food, they need to manually connect the cap and the dispensing tube back together via threads. This presents a problem: if the user forgets to replace the cap after feeding, the wet food inside the bag is not properly sealed and exposed to air, making it prone to spoilage (leading to bacterial growth and unpleasant odors, affecting the pet's health) or leaking out and resulting in waste. Utility Model Content

[0004] To overcome the drawbacks of existing pet food paste packaging bags, which rely on a movable sealing cap for the dispensing tube (as described in the background art), this invention provides a pet food paste packaging bag body that eliminates the need for a movable sealing cap. Each time a user feeds their pet, the wet food is automatically dispensed through the elastic cross-shaped dispensing nozzle. After feeding, the nozzle automatically closes when the user releases their hand. This eliminates the need for the user to remove and install the movable cap, providing convenience and preventing spoilage or leakage of the wet food due to poor sealing. This invention also provides a pet food paste packaging bag with an automatically sealing nozzle.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A pet wet food pouch with an automatic sealing nozzle includes a paste-like wet food packaging bag body and a nozzle. The nozzle includes an outer tube and a dispensing nozzle. The upper and lower ends of the outer tube are open structures. The upper end of the outer tube has an integrally formed annular hollow retaining ring. The dispensing nozzle has a circular structure with a cross-shaped slit in the middle as the dispensing outlet. The outer diameter of the dispensing nozzle is larger than the inner diameter of the outer tube. The dispensing nozzle is fixedly installed inside the upper end of the outer tube and located below the retaining ring. The lower end of the outer tube has an internal thread, and the outer side of the dispensing tube of the paste-like wet food packaging bag body has an external thread. The lower end of the outer tube and the dispensing tube are fixedly installed together by the threads, and the lower end of the dispensing nozzle and the upper end of the dispensing tube are in sealed contact.

[0006] Furthermore, the discharge nozzle is made of silicone, but any elastic material can also be used.

[0007] Furthermore, a tapered buckle can be installed on the outer end of the discharge pipe, and an annular buckle can be installed on the lower end of the outer sleeve, so that the outer sleeve and the discharge pipe are sealed together.

[0008] Furthermore, the outer end of the discharge pipe and the inner end of the outer sleeve can be installed together by an interference fit.

[0009] Furthermore, the outlet of the dispensing nozzle is in a sealed structure when the pet wet food bag is not subjected to external force, and in an open structure when the pet wet food bag is subjected to external force.

[0010] Furthermore, the discharge port of the discharge nozzle is not limited to a cross shape, but can be any shape.

[0011] Furthermore, the outer tube and the discharge nozzle are not limited to a circle, and can adopt any matching shape.

[0012] Furthermore, a protective film is installed on the discharge port of the discharge nozzle.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: The main body of the paste-like wet food packaging bag does not require a movable sealing cap. Each time the user feeds their pet, the wet food is squeezed out by hand through the main body of the packaging bag, and the elastic cross-shaped outlet automatically opens to release the wet food. After releasing the hand, the outlet automatically closes. This reduces the process of removing and installing the movable cap, providing convenience to the user and preventing problems such as forgetting to close the sealing cap after feeding, spoilage of the wet food due to poor sealing, or leakage from the packaging bag. In summary, this utility model has good application prospects. Attached Figure Description

[0018] Figure 1 , 2 As shown in Figures 3 and 4, the pet wet food bag with an automatic sealing nozzle includes a paste-like wet food packaging bag body 3 (filled with paste-like wet food) and a nozzle. The nozzle includes an outer tube 1 and a dispensing nozzle 2. The upper and lower ends of the outer tube 1 are open structures. The upper end of the outer tube 1 has an integrally formed annular hollow retaining ring 101. The dispensing nozzle 2 is circular. A cross-shaped slit is distributed in the middle of the dispensing nozzle 2 as a dispensing outlet 21. The outer diameter of the dispensing nozzle 2 is larger than the inner diameter of the outer tube 1. The dispensing nozzle 2 is fixedly installed inside the upper end of the outer tube 1 and is located below the retaining ring. The lower end of the outer tube 1 has an internal thread, and the outer side of the dispensing pipe 31 of the paste-like wet food packaging bag body 3 has an external thread. The lower end of the outer tube 1 and the dispensing pipe 31 are fixedly installed together by threads. The lower end of the dispensing nozzle 2 and the upper end of the dispensing pipe 31 are in sealed contact.

[0019] Figure 1 , 2As shown in Figures 3 and 4, the discharge nozzle 2 is made of silicone, but any elastic material can also be used. A conical buckle can be installed on the outer end of the discharge tube 3, and a ring buckle can be installed on the lower end of the outer sleeve 1, sealing the outer sleeve 1 and the discharge tube 3 together. The outer end of the discharge tube 3 and the inner end of the outer sleeve 1 can also be installed together using an interference fit. When the body of the paste-like wet grain packaging bag 3 is not subjected to external force, the discharge port 21 of the discharge nozzle is in a sealed structure; when external force is applied to the body of the paste-like wet grain packaging bag 3, the discharge port 21 of the discharge nozzle is in an open structure. The discharge port 21 of the discharge nozzle is not limited to a cross shape and can be any shape. The outer sleeve 1 and the discharge nozzle 2 are not limited to circles and can be any matching shape. A protective film is installed on the discharge port of the discharge nozzle; the protective film should be torn off before use.

[0020] Figure 1 , 2 As shown in Figures 3 and 4, this utility model is based on the body 3 (made of plastic) of a paste-like wet food packaging bag. The body 3 does not require a movable sealing cap. The outer sleeve 1 and the dispensing nozzle 2 can be easily installed on the upper end of the dispensing pipe 31 of the body 3 via threads, snap-fit, or interference fit. Each time a user feeds their pet, squeezing wet food through the body 3, the pressure of the wet food inside the body 3 causes the elastic cross-shaped dispensing opening 21 of the nozzle to automatically open and release the wet food. After squeezing out the wet food and releasing the hand, the dispensing opening 21 automatically closes due to the elastic force of the nozzle, as the pressure is gone. This invention reduces the process of removing and installing the movable cap, providing convenience to the user and preventing problems such as forgetting to close the sealing cap after feeding, spoilage of the wet food due to poor sealing, or leakage from the body 3.
