[0039] Please refer to Figure 1-5 , a square pet replaceable vacuum bottle, comprising an outer bottle 1, a shoulder sleeve 2, a screw cap 3, an inner liner 4, a piston 5 and an end cap 6. Specifically, the shoulder sleeve 2 is fixedly connected to the bottle mouth of the outer bottle 1, and four limiting mechanisms 201 are arranged on the inner wall of the shoulder sleeve 2, and the limiting mechanisms 201 are distributed at equal intervals, and the centers of two adjacent limiting mechanisms 201 are 90° apart, and one end of the limiting mechanism 201 is sunken, and an insertion channel 202 is formed between two adjacent limiting mechanisms 201, and there are four insertion channels 202 in total; the screw cap 3 is detachably connected to the shoulder sleeve 2, and four limiting blocks 301 are arranged on the outer wall of one end of the screw cap 3, and the limiting blocks 301 and the limiting blocks 301 are connected to the limiting blocks 202. The inner liner 4 is adapted to the positioning mechanism 201, the limiting block 301 can be inserted into the insertion channel 202 and can be rotated to the bottom of the limiting mechanism 201, thereby limiting the vertical position of the screw cap 3; the inner liner 4 is detachably connected to the screw cap 3, and the inner liner 4 is located in the outer bottle 1, and the inner liner 4 is replaceable. By making the inner liner 4 detachable and replaceable, the remaining parts except the inner liner 4 can be reused; the piston 5 is arranged in the inner liner 4, and the outer wall of the piston 5 is tightly fitted with the inner wall of the inner liner 4; the end cover 6 is buckled on the screw cap 3.
[0040] Furthermore, a first stopper 203 is provided below the two opposite limiting mechanisms 201 , and the first stopper 203 is matched with the limiting block 301 . The first stopper 203 can limit the movement of the limiting block 301 , thereby limiting the range of motion of the limiting block 301 (screw cover 3 ).
[0041] Furthermore, a second stopper 204 is provided under each limiting mechanism 201, and the second stopper 204 is located between the insertion channel 202 and the first stopper 203. The second stopper 204 is adapted to the limiting block 301. When the limiting block 301 rotates to the position of the second stopper 204, its outer wall will be rubbed and clamped with the outer wall of the second stopper 204, so that the limiting block 301 (screw cover 3) is fixed here, thereby limiting the lateral position of the screw cover 3.
[0042] Furthermore, two corners of the limiting block 301 are arc surfaces.
[0043] Furthermore, the top surface of the limiting mechanism 201 is lower than the top surface of the shoulder sleeve 2, and there is a height difference between the limiting mechanism 201 and the shoulder sleeve 2, and this height difference forms a mounting groove 205. A flange 302 is provided on the rotary cover 3, and the flange 302 is located in the mounting groove 205, that is, the rotary cover 3 is placed on the shoulder sleeve 2.
[0044] Furthermore, a first thread 303 is provided on the inner wall of the screw cap 3, and a second thread 401 is provided at the bottle mouth of the liner 4. The second thread 401 is adapted to the first thread 303. The screw cap 3 and the liner 4 are connected by thread matching, which can be disassembled and assembled conveniently.
[0045] Four latching protrusions 101 are arranged on the outer wall of the bottle mouth of the outer bottle 1, and each outer wall is provided with a latching protrusion 101. Four latching grooves 206 are also arranged on the inner wall of the shoulder sleeve 2, and each inner wall is provided with a latching groove 206. The latching grooves 206 are adapted to the latching protrusions 101, that is, the shoulder sleeve 2 is fixedly connected to the bottle mouth of the outer bottle 1 through the latching cooperation between the latching grooves 206 and the latching protrusions 101.
[0046] Two air holes 402 are arranged at the bottom of the inner container 4. The air holes 402 play a role in balancing the air pressure, and the arranged air holes 402 help to push the piston 5 to discharge the material.
[0047] In this embodiment, the outer bottle 1 and the screw cap 3 are both square structures.
[0048] In this embodiment, the outer bottle 1, the shoulder sleeve 2, the screw cap 3, the inner liner 4 and the end cap 6 are all made of PET material.
[0049] The utility model also includes a head cap (not shown) and a pump core (not shown), and the pump core can be snapped into the screw cap 3. It should be noted that the invention of the utility model does not include a head cap and a pump core, so the utility model can use a matching head cap and pump core on the market.
[0050] The utility model is a square PET replaceable vacuum bottle, and its working principle is explained in conjunction with the accompanying drawings in the specification:
[0051] When the content (lotion, cream) in the inner liner 4 is used up, first rotate the screw cap 3 to remove the limiting block 301 from the limiting mechanism 201 and insert it into the channel 202 to achieve a detachable connection between the screw cap 3 and the inner liner 4, then take the screw cap 3 and the inner liner 4 out of the outer bottle 1, and then unscrew the used inner liner 4, the inner liner 4 is detachably connected to the screw cap 3 through a thread, unscrew the lid 7 on the new inner liner 4, the lid 7 is detachably connected to the inner liner 4 through a thread, replace the new inner liner 4, and reinstall the new inner liner 4 into the outer bottle 1.
[0052] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
