Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bottles, and particularly relates to a high-barrier vacuum bottle. Background Art

[0002] With the rapid improvement of living standards, people have higher and higher requirements for the efficacy of cosmetics. Many natural efficacy ingredients have been introduced into cosmetics, but these efficacy ingredients are extremely unstable and easy to oxidize, which will lead to weakened efficacy. Currently, the most commonly used barrier containers are vacuum bottles or double-layer bottles, but these cannot completely block oxygen. Most of the main body materials of vacuum pumps are PP, and the oxygen transmission rate of PP is high. The larger the contact area between the bottle pump and the container, the more oxygen penetrates into the container from the air. At the same time, a certain amount of oxygen will also penetrate into the liquid outlet channel of the pump core, thus oxidizing the cosmetics.

[0003] For example, there is a Chinese patent with the publication number CN115281433A, which relates to a cosmetic container and cosmetics, and solves the problem that the content cannot be discharged smoothly by the pump, enabling the user to discharge the remaining content without opening the inner cover of the container and using hands or other tools, making it more convenient to use; however, the Chinese patent with the publication number CN115281433A only uses a sealing ring to seal at the container injection port, cannot achieve a good sealing effect, and has poor oxygen barrier property, which will cause oxygen to penetrate into the cosmetics through the bottle body and the liquid outlet channel of the pump core, thereby oxidizing the cosmetics. Content of the Utility Model

[0004] In order to solve the problem of poor oxygen barrier property of cosmetic packaging bottles, the utility model provides a high-barrier vacuum bottle, which can effectively isolate oxygen and prevent oxygen in the air from penetrating into the container to oxidize the cosmetics.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions: A high-barrier vacuum bottle, comprising

[0006] A vacuum pump, including a connecting ring arranged inside the vacuum pump, with a pump core and a pump sleeve respectively connected to both ends of the connecting ring, and a tip provided at the bottom of the pump core;

[0008] In this technical solution, a barrier bag is arranged inside the outer container of the vacuum bottle to effectively block the penetration of external oxygen and prevent the oxidation of cosmetics; a pointed corner that can pierce the barrier bag is provided at the bottom of the pump core. After the pump core is inserted into the barrier bag, there is no need to connect a suction tube, and the barrier bag can be shrunk by pressing the vacuum pump to achieve discharging. When the cosmetics are used up, only the barrier bag containing the cosmetics needs to be replaced separately to continue using, without replacing the entire packaging bottle.

[0009] The present utility model is further configured as follows: a first convex ring and a second convex ring are provided on the outer side of the connecting ring, a first concave ring and a second concave ring are provided on the inner side of the pump sleeve, and the second convex ring and the first concave ring are snap-connected.

[0010] In this technical solution, the connecting ring and the pump sleeve are snap-connected through the convex ring and the concave ring to form a seal. Two snap-connection structures are provided to ensure that the connecting ring and the pump sleeve are not easily separated, ensuring the sealing performance.

[0011] When the cosmetic is not in use, the connecting ring is placed above the pump sleeve, and the second convex ring and the first concave ring are snap-connected to prevent the pump core from separating from the pump sleeve during transportation. The cosmetic is sealed in the sealed space in the barrier bag by the sealing film.

[0012] When using the cosmetic for the first time, press the pressing head. The pressing head drives the pump core and the connecting ring to move downward. The first convex ring and the first concave ring are snap-connected, and the second convex ring and the second concave ring are snap-connected. The connecting ring is completely snapped into the pump sleeve to form a sealed structure with the barrier bag, ensuring that the cosmetic is also in a sealed space after starting to be used and is not easily oxidized.

[0013] The present utility model is further configured as follows: the connecting ring includes a cylindrical hollow ring body with an open upper end. An opening is provided at the bottom of the hollow ring body, and a through hole matching the pump core is connected at the opening. The pump core is hermetically connected in the through hole.

[0014] In this technical solution, a through hole is provided in the middle of the connecting ring, and the shape of the through hole matches the pump core. The pump core is inserted into the through hole. When the pressing head is pressed, the liquid outlet channel in the pump core is communicated with the liquid outlet on the pressing head, and the sharp angle under the pump core pierces the sealing film on the barrier bag. The barrier bag is compressed, and the cosmetic flows out from the liquid outlet.

[0015] The present utility model is further configured as follows: the upper part of the pump core is connected with a pressing head, a liquid outlet channel is provided inside the pump core, a telescopic structure is provided at the upper part of the pump core, a middle part in the shape of a through cylindrical shape is provided in the middle of the pump core, the lower end of the middle part is connected to the pointed part of the pump core, the pointed part is a through cylindrical structure with an inclined bottom end, and the diameter of the middle part of the pump core is larger than the diameter of the pointed part.

[0016] In this technical solution, one end of the pump core is connected to the pressing head, and the other end is connected to the connecting ring. When using the cosmetic for the first time, press the pressing head. The telescopic structure is compressed and drives the connecting ring to move downward, so that the sharp angle under the pump core pierces the sealing film on the barrier bag, and the cosmetic can reach the liquid outlet from the liquid outlet channel in the pump core.

[0017] The present utility model is further configured as follows: a first included angle is formed between the convex ring and the connecting ring, a second included angle is formed between the concave ring and the pump sleeve, and the angle of the first included angle is smaller than the angle of the second included angle.

[0018] In this technical solution, the angle between the convex ring and the connecting ring is smaller than the angle between the concave ring and the pump sleeve. The two are in interference fit to strengthen the clamping and enhance the sealing performance.

[0019] The present utility model is further configured as follows: The outer bladder is provided with a bladder body and a necking. The bladder body is a hollow cylinder with equal wall thickness and an open upper end. The necking is provided with a first connecting structure.

[0020] In this technical solution, the bladder body of the outer bladder is a hollow cylinder with equal wall thickness and an open upper end. The outer bladder, as an outer package, is arranged outside the barrier bag to play a protective role and prevent the barrier bag from being scratched.

[0021] The present utility model is further configured as follows: An outer cover is further provided above the vacuum pump. The outer cover is a hollow cylinder with equal wall thickness and an open lower end. The outer diameter of the outer cover is the same as the outer diameter of the outer bladder.

[0022] In this technical solution, the outer cover covers the upper part of the vacuum pump. The outer cover is a cylinder with equal wall thickness and an open lower end. It is combined with the outer bladder to form a whole cylinder. The outer cover is made of a transparent material.

[0023] The present utility model is further configured as follows: An edge is provided at the upper open end of the barrier bag, and a bag body is connected below the edge.

[0024] In this technical solution, the vacuum pump is connected to the necking of the outer bladder through a connecting structure to form a second sealed structure. When using cosmetics, the barrier bag shrinks. Since the outer bladder is sealed by the pump sleeve of the vacuum pump, a vacuum layer is formed between the barrier bag and the outer bladder, further strengthening the sealing performance of the vacuum bottle, isolating oxygen, and preventing the cosmetics from being oxidized.

[0025] The present utility model is further configured as follows: The pump sleeve of the vacuum pump is a hollow cylinder. The upper part of the pump sleeve matches the connecting ring. A groove is provided at the lower part of the pump sleeve. The upper half of the groove is connected to the edge of the barrier bag, and the lower half of the groove is provided with a second connecting structure, and the second connecting structure is connected to the first connecting structure.

[0026] In this technical solution, a second connecting structure on the necking of the outer bladder is hermetically connected to the first connecting structure on the pump sleeve, forming a sealed space inside the outer bladder, and pressing the edge of the barrier bag against the upper part of the groove to fix the barrier bag.

[0027] The present utility model is further configured as follows: The barrier bag is made of oxygen-barrier PET material. The upper end of the barrier bag is made of rigid PET material, and the lower end is made of flexible PET material.

[0028] In this technical solution, the upper end of the barrier bag is made of rigid PET material, which can be connected to the sealing film.

The diameter of the middle part of the pump core is larger than the diameter of the pointed part.

[0064] In this embodiment, one end of the pump core is connected to the pressing head, and the other end is connected to the connecting ring. When using the cosmetic for the first time, when the pressing head is pressed, the telescopic structure is compressed and drives the connecting ring to move downward, so that the sharp corner under the pump core pierces the sealing film on the barrier bag, and the cosmetic can reach the liquid outlet from the liquid outlet channel in the pump core.

[0065] A first included angle is formed between the convex ring and the connecting ring, and a second included angle is formed between the concave ring and the pump sleeve. The angle of the first included angle is smaller than the angle of the second included angle.

[0066] In this embodiment, the included angle between the convex ring and the connecting ring is smaller than the included angle between the concave ring and the pump sleeve. The two are in interference fit to strengthen the clamping and enhance the sealing performance.

[0067] The outer bladder is provided with a bladder body and a necking. The bladder body is an equal-wall-thickness hollow cylinder with an open upper end. The necking is provided with a first connection structure.

[0069] An outer cover is further provided above the vacuum pump. The outer cover is an equal-wall-thickness hollow cylinder with an open lower end. The outer diameter of the outer cover is the same as the outer diameter of the outer bladder.

[0070] In this embodiment, the vacuum pump is covered with an outer cover above. The outer cover is an equal-wall-thickness cylinder with an open lower end. It is combined with the outer bladder to form an entire cylinder. The outer cover is made of a transparent material.

[0071] A rim is provided at the upper open end of the barrier bag, and a bag body is connected below the rim.

[0072] In this embodiment, the vacuum pump is connected to the necking of the outer bladder through a connection structure to form a second closed structure. When the cosmetic is used, the barrier bag shrinks. Since the outer bladder is sealed by the pump sleeve of the vacuum pump, a vacuum layer is formed between the barrier bag and the outer bladder, further strengthening the sealing performance of the vacuum bottle, isolating oxygen, and preventing the cosmetic from being oxidized.

[0073] The pump sleeve of the vacuum pump is a hollow cylinder. The upper part of the pump sleeve matches the connecting ring. The lower part of the pump sleeve is provided with a groove. The upper half of the groove is connected to the edge of the barrier bag, and the lower half of the groove is provided with a second connecting structure, which is connected to the first connecting structure.
