Technical Field
[0001] This utility model belongs to the field of packaging container technology, specifically a vacuum bottle with a replaceable inner bottle. Background Technology
[0002] Traditional double-walled cosmetic vacuum bottles have an inner bottle installed inside an outer bottle, with the two bottles tightly fastened together. The inner bottle cannot be replaced, and once the liquid in the inner bottle is used up, the entire vacuum bottle must often be discarded. Because cosmetic vacuum bottles are relatively expensive to manufacture, this results in significant resource waste. Furthermore, these double-walled vacuum bottles are generally made of plastic, which is difficult to degrade after disposal. The residual liquid inside the cosmetics can then turn into harmful substances, polluting the environment.
[0003] In recent years, some manufacturers have also developed vacuum bottles with replaceable inner bottles, but the replacement structure is relatively complex and the replacement is not convenient, making it difficult for general consumers to use. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a vacuum bottle with a replaceable inner bottle, which is convenient to replace, energy-saving and environmentally friendly.
[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0006] A vacuum bottle with a replaceable inner bottle includes an outer bottle and an inner bottle. The outer bottle has an opening at the bottom and a rotating sleeve is provided inside the outer bottle. The rotating sleeve has an M-shaped groove on its side wall, and the lower edge of the groove has several groove inlets and groove outlets. The inner bottle has a protrusion on its side wall at the bottle mouth. The protrusion can enter the groove from the groove inlet and slide out of the groove from the groove outlet.
[0007] Furthermore, the replaceable inner bottle vacuum bottle also includes a large ring and a spring. The outer bottle has an outer bottle opening at its top, the large ring is installed at the outer bottle opening, and the spring is installed between the large ring and the inner bottle opening. Before the inner bottle is installed into the outer bottle, pushing the inner bottle upwards compresses the spring. The protrusion enters the slide groove from the inlet and slides along the slide groove. The inner bottle rotates under the action of the protrusion, while the spring force pushes the inner bottle downwards, thus fixing the inner bottle in place and enabling replacement of the inner bottle by pressing.
[0008] Furthermore, the vacuum bottle with replaceable inner bottle also includes a spring sleeve, which is installed between the bottle mouth of the inner bottle and the large ring, and the spring is installed between the large ring and the spring sleeve. Before the inner bottle is installed into the outer bottle, pushing the inner bottle upwards causes the inner bottle mouth to push the spring sleeve, compressing the spring. The protrusion enters the slide groove from the slide groove inlet and slides along the slide groove. The inner bottle rotates under the action of the protrusion, and simultaneously, the spring force pushes the spring sleeve downwards. The spring sleeve pushes the inner bottle downwards, thus securing the inner bottle in place.
[0009] Furthermore, the groove includes a low point, and the protrusion is located at the low point when the inner bottle is fixed to the outer bottle.
[0010] Furthermore, the rotating sleeve includes an upper rotating sleeve and a lower rotating sleeve. The inner wall of the upper rotating sleeve is provided with a continuous upper sliding groove, and the lower rotating sleeve is provided with a plurality of lower sliding grooves. The upper sliding groove and the plurality of lower sliding grooves constitute the sliding groove.
[0011] Furthermore, the protrusion is cylindrical.
[0012] Furthermore, the vacuum bottle with replaceable inner bottle also includes an outer ring, a cap, and a pump core assembly. The outer ring has a through hole in the middle, and the cap passes through the through hole and connects to the pump core assembly. When the outer ring is rotated, the rotating sleeve is driven to rotate.
[0013] Furthermore, the outer ring has a retraction hole at its bottom and a retraction wing at its upper part, the retraction wing being able to enter the retraction hole.
[0014] Furthermore, the pump core assembly is installed to the outer bottle opening via a large ring; a large ring limiting block is provided on the top surface of the large ring, and a cap limiting block is provided at the bottom of the cap. When the cap limiting block is located on the large ring limiting block, the cap cannot be pressed down; when the cap limiting block avoids the large ring limiting block, the cap can be pressed down.
[0015] Furthermore, a plug is installed at the inner bottle opening.
[0016] This utility model discloses a vacuum bottle with a replaceable inner bottle, which allows for quick and convenient replacement of the inner bottle, is environmentally friendly, and improves the customer experience. The vacuum bottle with the replaceable inner bottle also allows for locking of the cap and inner bottle, preventing leakage of cosmetics during transportation or while the user is traveling, thus improving the cleanliness of the cosmetic packaging.

[0035] The following detailed description, in conjunction with the accompanying drawings, provides a vacuum bottle with a replaceable inner bottle according to this utility model. In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," and "bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Terms such as "first" and "second" do not indicate the importance of components and therefore should not be construed as limitations on this utility model. The specific dimensions and values used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of this utility model.
[0036] like Figure 1 , 2 As shown in Figure 3, this utility model discloses a vacuum bottle with a replaceable inner bottle, comprising an outer bottle 14 and an inner bottle 13. The bottom of the outer bottle 14 is open, and a rotating sleeve is provided inside the outer bottle 14. The side wall of the rotating sleeve is provided with an M-shaped groove 100. Figure 15 As shown, the lower edge of the chute 100 is provided with several chute inlets 200 and chute outlets 300; the inner bottle 13 has a protrusion on the side wall at the bottle mouth, and the protrusion can enter the chute 100 from the chute inlet.
[0037] Preferably, to enable the replacement of the inner bottle by pressing, the vacuum bottle in this embodiment further includes a large ring 6 and a spring 9. An outer bottle opening is provided at the top of the outer bottle 14, the large ring 6 is installed at the outer bottle opening, and the spring 9 is installed between the large ring 6 and the inner bottle opening. To fix the relative position of the large ring 6 and the outer bottle 14 circumferentially, as follows... Figure 12 As shown, a large circle positioning block 63 is set at the edge of the large circle, as... Figure 17 As shown, a positioning groove 141 is provided at the outer bottle opening, and a large positioning block 63 is installed in the positioning groove 141. Before the inner bottle 13 is installed into the outer bottle 14, the inner bottle 13 is pushed upward, compressing the spring 9. The protrusion enters the slide groove 100 from the slide groove inlet 200 and slides along the slide groove 100. The inner bottle 13 rotates under the action of the protrusion, and at the same time, the elastic force of the spring 9 pushes the inner bottle 13 downward, thus fixing the inner bottle 13 in place and realizing the replacement of the inner bottle by pressing.
[0038] For better results, such as Figure 1 and 2As shown, the vacuum bottle with replaceable inner bottle in this embodiment also includes a spring sleeve 8, which is installed between the bottle mouth of the inner bottle 13 and the large ring 6. A spring 9 is installed between the large ring 6 and the spring sleeve 8. Before the inner bottle 13 is installed into the outer bottle 14, the inner bottle 13 is pushed upwards. The inner bottle mouth pushes the spring sleeve 8 to compress the spring 9. The protrusion enters the slide groove 100 from the slide groove inlet 200 and slides along the slide groove 100. The inner bottle 13 rotates under the action of the protrusion. At the same time, the elastic force of the spring 9 pushes the spring sleeve 8 downwards. The spring sleeve 8 pushes the inner bottle 13 downwards, and the inner bottle 13 is installed and fixed.
[0039] like Figure 15 As shown, the chute 100 includes a low point 112. When the inner bottle 13 is fixed to the outer bottle 14, the protrusion is located at the low point 112. The rotating sleeve can be integrally formed, or it can be divided into an upper rotating sleeve 10 and a lower rotating sleeve 11. The inner wall of the upper rotating sleeve 10 is provided with a continuous upper wall 101 of the chute, and the lower rotating sleeve 11 is provided with several lower walls 111 of the chute. The upper wall 101 of the chute and the several lower walls 111 of the chute constitute the chute 100. In order for the protrusion to slide more smoothly in the chute, the protrusion is cylindrical in this embodiment. Each lower wall 111 of the chute has a low point 112. The number of lower walls 111 of the chute and the protrusion can be one or more. In this embodiment, the number of lower walls 111 of the chute and the protrusion is set to four.
[0040] like Figure 1 and 2 As shown, the vacuum bottle with replaceable inner bottle in this embodiment also includes an outer ring 4, a cap 2, and a pump core assembly 5. A through hole is provided in the middle of the outer ring 4, and the cap 2 passes through the through hole and connects to the pump core assembly 5; as shown... Figure 9 As shown, the cap 2 is provided with a cap inlet 23 and a cap outlet 21, and the cap inlet 23 is connected to the outlet of the pump core assembly 5. Figure 10 As shown, an outer ring 4 has a notch 41 on its side, and the liquid outlet 21 of the cap is located in the notch 41. Rotating the outer ring 4 causes the cap 2 to rotate. Alternatively, the outer ring 4 and the cap 2 can be integrated. In this case, pressing the cap 2 causes both the outer ring 4 and the cap 2 to move downwards together, and rotating the outer ring 4 causes both the cap 2 and the outer ring 4 to rotate together. Figure 11 As shown, the bottom of the outer ring 4 is provided with a retraction hole 42, as... Figure 16 As shown, the upper part of the cartridge case 8 is provided with a retraction wing 81, as... Figure 12 and 13 As shown, a large ring side hole 62 is provided around the top surface of the large ring 6, and the retracted wing 81 can pass through the large ring side hole 62 and enter the retracted hole 42.
[0041] The pump core assembly 5 is installed to the outer bottle opening via the large ring 6. For example... Figure 12 and 13 As shown, a large circle limiting block 61 is set on the top surface of the large circle 6, as... Figure 9As shown, a head cap 2 has a head cap limiting block 22 at its bottom. When the head cap limiting block 22 is positioned on the large ring limiting block 61, the head cap 2 cannot be pressed down; when the head cap limiting block 22 avoids the large ring limiting block 61, the head cap 2 can be pressed down. Furthermore, when the head cap limiting block 22 avoids the large ring limiting block 61, the retraction wing 81 can pass through the large ring side hole 62 and enter the retraction hole 42. The large ring 6 and the pump core assembly 5 can also be integrally formed.
[0042] If the inner bottle 13 is disposable, a plug 12 is installed at the opening of the inner bottle to seal the cosmetics inside. Figure 8 As shown, the top of the plug 12 is raised and has a weak point 121, through which the plug 12 can be punctured by the pump core assembly 5.
[0043] like Figure 1 and 2 The vacuum bottle with replaceable inner bottle in this embodiment also includes a push cap 1, a cover 3, a pump sleeve 7, a large piston 15, and a bottom cap 16. The top of the push cap 2 can be a detachable structure, that is, the top of the push cap 2 is set as the push cap 1. The cover 3 is installed on the top of the outer ring 4. The pump sleeve 7 is fitted onto the upper part of the outer bottle 14. The large piston 15 is installed on the lower part of the inner bottle 13, and the bottom cap 16 covers the bottom of the inner bottle 13.
[0044] The preferred working principle of the vacuum bottle with replaceable inner bottle in this embodiment is as follows:
[0045] like Figure 4 As shown, with the vacuum bottle with the replaceable inner bottle in the unlocked state (i.e., the cap can be pressed down), push the inner bottle in from the bottom of the outer bottle. For example... Figure 3 and 15 As shown, the protrusion on the inner bottle slides into the slide groove from the inlet 200, and the protrusion slides along the slide groove, causing the rotating sleeve to rotate; at the same time, the inner bottle moves upward, and since the retraction fin of the spring sleeve can enter the retraction hole at this time, the inner bottle pushes the spring sleeve to move upward, and the spring sleeve compresses the spring; the end of the pump core assembly pierces the blockage and enters the inner bottle. Figure 5 and 15 As shown, the protrusion reaches the highest point 101 on the upper wall of the chute, at which point it stops sliding. The inner bottle moves downwards under the action of the spring, and the protrusion falls back to the lowest point 112 on the lower wall of the chute. Figure 6 As shown, once the inner bottle is installed, you can press the pump cap to dispense the cosmetics from the vacuum bottle.
[0046] When the cosmetics in the inner bottle are used up and need to be replaced, such as Figure 5 As shown, press the bottom of the inner bottle, as... Figure 3 and 15 As shown, the protrusion on the inner bottle slides along the slide groove; when the protrusion slides to the high point 101 on the upper wall of another slide groove, it stops sliding. Under the action of the spring force, the spring sleeve pushes the inner bottle downward, and the protrusion moves downward from the slide groove outlet 300, and the inner bottle is removed.
[0047] like Figure 7 As shown, when the cap limiting block is on the large ring limiting block, the cap cannot be pressed down, and the vacuum bottle is locked. At this time, the ejector wing of the spring sleeve does not correspond to the ejector hole at the bottom of the outer ring. The ejector wing is limited by the bottom of the large ring and cannot move upward. At this time, the inner bottle cannot be pushed upward either, so the inner bottle is also locked and cannot be replaced.
[0048] Based on the description of the preferred embodiments of the present invention, it should be clear that the present invention as defined by the appended claims is not limited to the specific details set forth in the above description, and many obvious changes to the present invention without departing from the spirit or scope of the present invention may also achieve the purpose of the present invention.
