Description

TECHNICAL FIELD

[0001] The present application belongs to the field of packaging bags, and particularly relates to a pet food or medicine packaging bag. BACKGROUND

[0002] Some people raise pets, and most of them raise cats and dogs, and a small part of them raise other relatively rare pets, such as lizards, snakes, etc.

[0003] Pets need to eat. Taking cats as an example, in addition to fixedly eating granular solid cat food or wet cat cans as pet main food, pets carefully taken care of by owners also need to take snacks, nutritional supplements, health products, etc. according to their health conditions. If pets are sick, they also have the need to take medicine. These snacks, nutritional supplements, health products, and medicines are in the form of liquid, such as pure fish oil or medicines with fish oil as solvent, etc. And pets need to take a small amount of medicine quantitatively.

[0004] For these liquid pet foods or medicines, the traditional method is to use bottles, cans, bags, etc. for large packaging, and users take or measure them by themselves every time. But this causes the container to contact air, and components such as fish oil will quickly oxidize and spoil, and health products, medicines, etc. are also at risk of invalidation. In addition, the hands, eyes, and containers of users cannot be guaranteed to be very accurate, and errors are easy to cause, affecting the quantitative feeding effect.

[0005] Therefore, such liquid pet foods or medicines should be directly packaged according to the designed amount, and pet owners take the small packaging of the packaged pet foods or medicines when using, open it, feed it to the pet (or mix it into the pet main food), and then discard the packaging, which saves the time and energy of the user, and also saves the user's measuring device requirement.

[0006] Similar technical solutions for small packages of liquid food for humans can be considered, such as those provided by Chinese patents 201220278994.X (a folding opening small package of honey) by inventor Zhang Lianan and 201721146488.4 (a disposable squeeze package) by inventor Ye Libing. Both solutions are basically ok for humans to portion honey or jam, but both solutions have a special problem in the pet food or medicine industry: pets have a keen sense of smell, such as cats and dogs, who can smell through some not dense enough plastic film (this feature has been used by customs and other departments to crack down on smuggling and drug trafficking), and the behavior of pets is not completely controlled by the pet owner. Therefore, pets come into contact with these small packages placed in the home in daily life, and if the small packages contain liquid such as fish oil that is very tasty to pets and has a strong smell, pets will be motivated to attack the package if they smell the smell without being noticed, and will try to destroy the package with their claws and teeth, on the one hand causing loss and waste, and on the other hand leading to excessive intake. In addition, it is also necessary to make it opaque to prevent some ingredients from being sensitive to light and deteriorating when exposed to light, and to prevent pets from learning to identify the ingredients in the package by the naked eye.

[0007] Therefore, the applicant has improved and developed on the basis of Chinese patent 201220278994.X, and added structural features of sealing, firmness and opacity to ensure that it is suitable for packaging most liquid pet food or medicine. SUMMARY

[0008] The present application provides a packaging structure for small amounts of liquid pet food or medicine, comprising:

[0009] A packaging structure for small amounts of liquid pet food or medicine, comprising: an upper skin, a bottom plate; wherein the lower surface area of the upper skin is slightly larger than the upper surface area of the bottom plate, and the edge of the upper skin is tightly joined to the edge of the bottom plate, so that after containing liquid, the upper skin is slightly convex with excess, and the cavity between the upper skin and the bottom plate forms a packaging space; wherein the bottom plate is made of hard material, and the surface thereof is provided with a crease, the crease being located in the middle of the bottom plate; wherein the upper skin comprises at least one layer of high-density, flexible plastic film, and is opaque; wherein the bottom plate is opaque; further comprising: a bottom plate film, which is an opaque and easy-to-tear film, and the single-sided surface area thereof is smaller than the upper surface area of the bottom plate and is tightly joined to the central position of the upper surface of the bottom plate.

[0010] Further, the bottom plate film comprises at least one layer of foil made of aluminum or aluminum alloy, and the foil will directly contact the liquid to be packaged.

[0011] Further, the upper skin comprises at least one layer of foil made of aluminum or aluminum alloy, and the foil will directly contact the liquid to be packaged.

[0012] Further, the crease is located on the geometric symmetry axis of the bottom plate.

[0013] Further, the bottom plate comprises at least one layer of hard plastic, and the thickness is not less than 0.3mm.

[0014] Further, the upper skin is made of opaque material, or the upper skin is made of transparent material and coated with an opaque coating.

[0015] Further, the bottom plate is made of opaque material, or the bottom plate is made of transparent material and coated with an opaque coating.

[0016] The application also provides a storage structure for storing the above-mentioned small liquid pet food or medicine packaging structure, further improving the protection performance, comprising:

[0017] A storage structure for a small liquid pet food or medicine packaging structure can facilitate the storage or retrieval of multiple small liquid pet food or medicine packaging structures, comprising a storage box and a push-pull drawer. The push-pull drawer is placed in the storage box and can be pulled out or pushed in from one end of the storage box. The push-pull drawer is provided with multiple storage grooves. The length of each storage groove is exactly equal to the width of one side of the small liquid pet food or medicine packaging structure, and the width is exactly equal to the thickness of the small liquid pet food or medicine packaging structure after packaging the liquid, allowing the small liquid pet food or medicine packaging structure to be embedded in the storage groove, with the upper half exposed for easy retrieval, and without shaking or falling out under any movement. After any of the storage grooves has embedded the small liquid pet food or medicine packaging structure, the total height of the push-pull drawer itself and the exposed upper half of the small liquid pet food or medicine packaging structure embedded in the storage groove is less than the height of the storage box, allowing the fully loaded push-pull drawer to freely move in and out of the storage box.

[0018] The application provides a small liquid pet food or medicine packaging structure, which reduces the possibility of pet attacking the packaging by setting an opaque upper skin comprising at least one layer of high-density, flexible plastic, an opaque hard bottom plate, and an opaque bottom plate film tightly bonded to the bottom plate. On the other hand, it strengthens the firmness of the packaging itself, and on the other hand, it enhances the invisibility and light resistance of the packaging, preventing the ingredients from deteriorating under light. It improves the problem of pet scratching and biting the packaging, leading to waste and excessive intake, and the problem of deterioration of light-sensitive ingredients when using the existing packaging solution. Furthermore, the application also provides a storage structure for the above-mentioned independent packaging structure, which further improves the protection performance while meeting the requirement of consumers for easy retrieval, and on the other hand, has fixed grooves for clearly and conveniently counting the number of times of retrieval.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] In the description of this application, it should be understood that the terms "upper," "lower," "left," "right," etc., are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that any structure referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In particular, the understanding of the term "upper" following a noun in the claims should be understood as meaning that the entire inner and outer surfaces of the structure referred to by the noun conform to the definition of "upper."

[0026] It is necessary to make an additional explanation that "liquid" in this application has a special definition. In this application, it should be understood not only as "liquid pure substance" and "solution" that are clear and pure, but also as "suspension" that is a mixture formed by suspending small insoluble solid particles in a liquid, "emulsion" that is a mixture formed by dispersing small liquid droplets in another immiscible liquid, "colloid" that is flowable, "liquid crystal" that is flowable, and all other substances that are basically in a flow phase and can flow freely. In order to facilitate writing and expression, it is abstractly generalized as "liquid", which is different from the meaning of the ordinary physical term "liquid".

[0027] The specific embodiments, structures, features, and effects provided according to the application will be described in detail below in combination with the drawings and preferred embodiments.

[0028] As shown in the accompanying drawings Figure 1 , the epithelium 102 and the bottom plate 104 are tightly joined at the edge. Since the surface area of the epithelium 102 is relatively slightly larger, a packaging space is formed between the epithelium 102 and the bottom plate 104 for packaging a small amount of liquid pet food or medicine as described in the application. One side of the packaging space is limited by the hard bottom plate and is horizontal, and the other side is limited by the flexible epithelium and is slightly naturally bulged. The upper surface of the bottom plate refers to the side of the bottom plate close to the packaged object. A bottom plate film is tightly joined to the upper surface of the bottom plate. The bottom plate film is an aluminum foil. This is because the bottom plate is provided with a crease. Therefore, there may be defects at the crease, especially when the workmanship deviates, some are cut deep, and some are cut shallow. The aluminum foil covers this place to effectively enhance the light-shielding property, smell-probing resistance, and oxidation resistance. Based on the characteristics of the aluminum foil that is easy to tear and fold, it will not completely block the user from bending the bottom plate when taking it. The epithelium is a single-layer film made of TPU (polyurethane) and coated with an opaque coating. The bottom plate is made of hard material and has a thickness of 1.0 mm to provide a certain degree of protection against animal claws and teeth. The crease is located on the symmetry axis of the bottom plate, which can provide the user with the best hand feeling and facilitate the complete extrusion of the contents. When the user uses it, takes a packaging structure along the crease, and then the bottom plate will be broken in the middle, and the aluminum foil will be torn along with the broken bottom plate, and the packaged liquid will flow out along the opening of the crease.

[0029] In another embodiment, the epithelium shown in the accompanying drawings Figure 1 includes a layer of aluminum foil tightly joined under the single-layer film made of TPU (polyurethane) in addition to the single-layer film made of TPU (polyurethane). In this embodiment, since the aluminum foil already plays a role in light shielding, there is no need to additionally coat a light-shielding coating, but we believe that it is also possible to additionally coat a light-shielding coating, and the idea of multiple protection does not violate the concept of the application.

[0030] Regarding the thickness of the base plate, the applicant conducted an experiment. We made the base plate 0.3mm thick and coated it with catnip, which caused the cat to scratch and bite for about 2-3 minutes. The result was that it was not damaged, but scratch marks were left, which looked quite dangerous. The applicant speculated that it should not be less than 0.3mm, and preferably more than 1.0mm.

[0031] In addition, regarding the material of the epithelium, any flexible material other than TPU that is known on the application date or disclosed in other patents or documents can be made into an epithelium as long as it meets the characteristics of being dense and flexible.

[0032] As attached Figure 4 , 5 In the illustrated embodiment, since the packaging structure is a small-batch package, and pets typically need to consume liquids continuously over a period of time, pet owners will generally use and consume the package multiple times. This inevitably raises the question of how to store a large number of these packaging structures. The corresponding solution is to provide a storage box containing a pull-out drawer. The drawer has a fixed number of grooves, the width and length of which are matched to the packaging structure, allowing the packaging structure to be firmly embedded in the grooves and withstand a certain degree of movement from the drawer itself without detaching.

[0033] The embodiments described above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
