Description

Technical Field

[0001] This utility model belongs to the field of juice cup technology, and in particular relates to a juice cup with vacuum freshness-locking function. Background Technology

[0002] Summer is the peak season for juice cups, but due to the high temperatures in summer, juice is prone to spoilage. Commonly used juice cups cannot preserve juice for a long time. The main reason for juice spoilage is that it is affected by microorganisms in the air, which makes it difficult to preserve juice. Conventional juice preservation usually uses vacuuming and low-temperature processing methods.

[0003] Patent application CN201610752712.8 discloses a vacuum-sealed juice cup, comprising a cup body and a lid. The lid includes a top cover and a bottom cover, with a first air hole on the bottom cover and a first through hole on the top cover. An air pump is mounted on the lid, comprising an air pump positioning cylinder, an inner air pump cylinder, and an outer air pump cylinder. A pressing handle is mounted on the air pump. Pressing the handle expels air from the cup body; pressing the handle draws air out of the cup body; and returning the handle to its original position expels air from the air pump. The vacuum-sealed juice cup obtained using this invention features a vacuum device directly mounted on the lid, making it easy to carry. Furthermore, the high vacuum level achieved through the air pump ensures a high degree of vacuum within the cup.

[0004] Existing technologies use structures such as springs and air pumps to create a vacuum inside the cup, saving the effort required for vacuuming. However, there are still shortcomings: First, the juice needs to be poured into the cup as soon as it is pressed. If the juice is filtered before being poured into the cup, it is easy for the juice to be in contact with air for too long, allowing microorganisms and other impurities to enter the juice, which shortens the shelf life of the juice. Furthermore, the filter screens commonly built into the cups can become clogged with fruit particles after repeated use, making it impossible to pour out the juice later and affecting its use.

[0005] Furthermore, simply vacuuming the juice cup limits the preservation time of the juice inside. Low-temperature treatment of the juice cup would extend the preservation time. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this invention provides a juice cup with a vacuum-sealing function. By incorporating elongated grooves and a filter screen, the interior of the cup forms multiple intersecting fruit storage slots. When the filter screen is placed inside the cup, fruit residue in the stored juice is filtered into these storage slots and between the storage slots and the inner bottom surface of the cup. The elongated grooves and raised structures not only effectively protect the cup but also allow for the storage of ice cubes or other cooling items within the slots to keep the juice cool and fresh.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a juice cup with vacuum preservation function, comprising a cup body, a cup lid threadedly connected to the upper end of the cup body, multiple elongated grooves provided on the side wall of the cup body, a sleeve slidably disposed on the outside of the cup body, multiple protrusions slidably engaged with the elongated grooves on the inner circular surface of the sleeve, each protrusion having a placement groove inside, a filter screen slidably disposed inside the cup body, a storage groove at the bottom of the filter screen, and a vacuum assembly disposed inside the cup lid.

[0008] Optionally, a first sealing ring is provided between the cup body and the sleeve. Multiple sealing protrusions and mating grooves are evenly spaced along the circumferential direction on one side wall of the first sealing ring. The multiple sealing protrusions and mating grooves are engaged with each other, and the multiple mating grooves are engaged with the upper part of the cup body.

[0009] Optionally, the upper surface of the cup lid is provided with a groove, a piston plate is slidably disposed inside the groove, and a one-way valve is provided inside the piston plate and at the bottom of the groove.

[0010] Optionally, a support frame is provided above the piston plate inside the groove, and a tension rod is slidably arranged inside the support frame, with the lower end face of the tension rod fixedly connected to the upper end face of the piston plate.

[0011] Optionally, the upper end of the tension rod is rotatably provided with a handle.

[0012] Optionally, the outer wall of the filter screen is provided with multiple filter holes, and the interior of the filter screen is provided with multiple reinforcing rods.

[0013] Optionally, the outer circular surface of the casing is provided with anti-slip grooves on the outer side of each protrusion.

[0014] Optionally, a second sealing ring is provided between the cup body and the cup lid.

[0015] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0016] (1) By setting up a long groove, a filter screen and a storage groove, the present invention forms multiple fruit storage grooves that intersect with the long groove inside the cup. When the filter screen is placed inside the cup, the fruit residue in the juice stored inside the cup can be filtered into the filter storage groove and between the storage groove and the inner bottom surface of the cup. This allows the user to pour the juice directly into the cup without filtering, and when drinking the juice, the user will not drink the fruit residue, which effectively improves the user experience.

[0017] (2) By setting up structures such as long grooves, protrusions and placement grooves, the shell not only effectively protects the cup body, but also allows ice cubes and other cooling items to be stored inside the placement groove to cool down and lock in the freshness of the juice inside the cup, effectively improving the preservation time of the juice inside the juice cup.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1:

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a juice cup with vacuum preservation function includes a cup body 10, a cup lid 11 threadedly connected to the upper end of the cup body 10, multiple elongated grooves 12 provided on the side wall of the cup body 10, a sleeve 13 slidably provided on the outside of the cup body 10, multiple protrusions 14 provided on the inner circular surface of the sleeve 13 that can slide and cooperate with the elongated grooves 12, and a placement groove 15 provided inside each protrusion 14, a filter screen 16 slidably provided inside the cup body 10, a storage groove 30 provided at the bottom of the filter screen 16, and a vacuum assembly provided inside the cup lid 11.

[0028] Specifically, the second sealing ring 22 is made of elastic material, and the setting of the second sealing ring 22 effectively increases the sealing between the cup body 10 and the cup lid 11.

[0029] The interior of the placement slot 15 can store cooling materials such as ice cubes. The cooling materials can cool and preserve the juice inside the cup body 10 through the protrusion 14 and the long slot 12, thereby improving the freshness of the juice.

[0030] Multiple long grooves 12 are evenly distributed in a ring on the side wall of the cup body 10, so that a fruit storage groove is formed between every two long grooves 12 on the inner wall of the cup body 10. The arrangement of long grooves 12 not only increases the contact area between the protrusion 14 and the cup body 10, but also allows the cooling material stored in the placement groove 15 to better cool the juice inside the cup body 10.

[0031] When the filter 16 is placed inside the cup body 10, it works with the storage compartment 30 and multiple fruit storage compartments to filter the fruit particles into the space between the storage compartment 30 and the cup body 10 and into the multiple fruit storage compartments, making it more convenient for users to drink juice.

[0032] When the filter 16 is placed inside the cup body 10, a lot of fruit particles accumulate between the bottom of the filter 16 and the bottom of the cup body 10, making it impossible for the lower end of the filter 16 to make close contact with the bottom surface of the cup body 10. With the storage compartment 30, the fruit particles can be well stored inside the storage compartment 30, so that the entire filter 16 can be completely placed inside the cup body 10, thus filtering all the juice inside the cup body 10.

[0033] Further, such as Figure 3 and Figure 5 As shown, a groove 23 is provided on the upper surface of the cup lid 11, and a piston plate 24 is slidably disposed inside the groove 23. A one-way valve 25 is provided inside the piston plate 24 and at the bottom of the groove 23.

[0034] Specifically, the one-way valve 25 is a common one-way valve. The one-way valves set inside the piston plate 24 and at the bottom of the groove 23 can only expel the air inside the cup body and cannot draw in the air from the outside into the cup body or the groove 23. This allows the air inside the cup body 10 to be expelled when the piston plate 24 is pulled.

[0035] Further, such as Figure 3 As shown, a support frame 26 is provided above the piston plate 24 inside the groove 23. A tension rod 27 is slidably provided inside the support frame 26. The lower end face of the tension rod 27 is fixedly connected to the upper end face of the piston plate 24. A handle 28 is rotatably provided at the upper end of the tension rod 27.

[0036] Specifically, by pulling the handle 28, the handle 28 drives the tension rod 27, which in turn drives the piston plate 24, thus drawing air out of the cup body 10 and creating a vacuum environment inside the cup body 10, thereby improving the preservation time of the juice inside the cup body 10.

[0037] The handle 28 can also be used as a carrying handle for the juice cup, making it easier to pick up and improve the convenience of using the juice cup.

[0038] Further, such as Figure 1 and Figure 6 As shown, a first sealing ring 19 is provided between the cup body 10 and the shell 13. Multiple sealing protrusions 20 and mating grooves 21 are evenly spaced along the circumferential direction on one side wall of the first sealing ring 19. The multiple sealing protrusions 20 and the placement groove 15 are engaged with each other, and the multiple mating grooves 21 are engaged with the upper part of the cup body 10.

[0039] Specifically, the multiple fruit storage slots on the inner side wall of the cup body 10 allow the upper ends of the multiple fruit storage slots to engage with the matching slots 21, and the sealing protrusions 20 and matching slots 21 engage with each other. The cup body 10 and the cup lid 11 also compress the first sealing ring 19, thus fixing the shell 13 and preventing it from slipping off. Furthermore, the first sealing ring 19 is located between the cup body 10 and the cup lid 11, which can further increase the sealing performance between the cup body 10 and the cup lid 11.

[0040] Further, such as Figure 3 and Figure 4 As shown, the outer wall of the filter screen 16 is provided with a plurality of filter holes 17, and the interior of the filter screen 16 is provided with a plurality of reinforcing rods 18.

[0041] Specifically, the filter hole 17 can effectively separate the juice and fruit particles inside the cup body 10. The multiple reinforcing rods 18 can support the inner circular surface of the filter screen 16, so that the filter screen 16 can form an outward supporting force on the side wall of the cup body 10 inside the cup body 10. When the inside of the cup body 10 is vacuumed, the filter screen 16 and the reinforcing rods 18 can effectively prevent the cup body 10 from deforming under the action of external atmospheric pressure, thus improving the sturdiness of the juice cup.

[0042] Furthermore, the uppermost reinforcing rod 18 can also serve as a handle for the filter screen 16, making it easier to insert and remove the filter screen 16 from the cup body 10, thus improving the ease of use of the filter screen 16.

[0043] First, pour the juice into the inside of the cup body 10. Then, insert the filter 16 into the inside of the cup body 10. Next, put ice cubes or other materials for cooling into the inside of the multiple placement slots 15. Put the first sealing ring 19 onto the upper port of the cup body 10, so that the upper part of the cup body 10 and the multiple mating slots 21 on the first sealing ring 19 engage with each other. Then, put the sleeve 13 onto the outside of the cup body 10, so that the upper port of the placement slot 15 engages with the multiple sealing protrusions 20 on the first sealing ring 19. Next, put the second sealing ring 22 into the inside of the cup lid 11, and then screw the cup lid 11 onto the upper port of the cup body 10.

[0044] Finally, by repeatedly pulling the handle 28, a vacuum is created inside the cup 10, allowing the juice inside the cup 10 to be in a low-temperature vacuum environment, thus achieving the effect of preservation.

[0045] Example 2:

[0046] Based on Example 1, further examples are made, such as... Figure 1 As shown, the outer circular surface of the housing 13 is provided with anti-slip grooves 29 on the outer side of each protrusion 14.

[0047] Specifically, when the protrusion 14 is filled with cooling material, the outer surface of the casing 13 will be cooler than the protrusion 14. If the user holds it directly, it will cause discomfort. The anti-slip groove 29 can effectively prevent the user from contacting the cooler area on the casing 13, thus improving the user experience.
