Description

Technical Field

[0001] The utility model relates to a vacuum bottle, in particular to a vacuum bottle with an inwardly retracted head cap. Background Art

[0002] A vacuum bottle refers to a container that can isolate gas from the outside temperature or a container that can isolate external bacteria. In the field of cosmetics, the contents of a vacuum bottle can be completely isolated from the air to prevent the product from oxidizing, deteriorating, and breeding bacteria due to contact with the air. The structure of a vacuum bottle in the prior art generally includes a bottle body, an inner liner is placed in the bottle body, a sleeve is inserted at the upper end of the inner liner, a pump body passes through the sleeve, a straw extending into the inner liner is connected to the lower end of the pump body, a head cap is connected to the upper end of the pump body, and a spring is provided between the head cap and the pump body. When in use, by pressing the head cap, liquid will flow out from the mouth of the head cap. During use, the following problems often occur: when the vacuum bottle is placed in a bag, it is easily squeezed by other items in the bag, causing the head cap to be easily pressed by mistake, causing liquid to be squeezed out of the vacuum bottle, resulting in waste. Utility Model Content

[0003] In view of the above-mentioned defects of the prior art, the purpose of the utility model is to provide a vacuum bottle with a retracted head cap.

[0004] The technical solution of the utility model is: a head-cap retracted vacuum bottle, which includes a lower bottle body, an inner liner is placed in the lower bottle body, a pump body is installed on the upper end of the inner liner, a head cap is connected to the upper end of the pump body, a nozzle is provided at the front end of the head cap, a pressing sleeve is fixedly connected to the upper end of the inner liner, an upper bottle body is fixedly connected to the upper end of the lower bottle body, an outer sleeve is connected to the outer shell of the upper bottle body, the outer sleeve has a through hole that runs through from top to bottom and allows the head cap to pass through, a slot with an opening facing upward and for the nozzle to be inserted into the outer edge of the top of the outer sleeve, two oblique grooves are distributed along the circumference of the upper side wall of the upper end of the upper bottle body, two protrusions are distributed along the circumference of the middle outer wall of the pressing sleeve, the protrusions pass through the oblique grooves and slide in cooperation with the oblique grooves.

[0005] Furthermore, an annular convex ring is provided on the outer wall of the lower end of the upper bottle body, and a groove is provided on the inner wall of the lower end of the outer sleeve. The convex ring is inserted into the groove and rotates with the groove.

[0006] Furthermore, the inner wall of the outer sleeve is provided with two sliding grooves extending up and down, and the ends of the protrusions are inserted into the sliding grooves.

[0007] Furthermore, the lower end of the inclined slot has a first horizontal locking slot, and the upper end of the inclined slot has a second horizontal locking slot.

[0008] The beneficial effect of using the vacuum bottle with a retractable head cap provided by the utility model is that the head cap can be retracted into the outer coat when not in use, so when the vacuum bottle is placed in a bag, the head cap is not easily pressed by mistake.

DETAILED DESCRIPTION

[0018] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0019] like Figure 1 — Figure 8 As shown, a head-cap retracting type vacuum bottle comprises a lower bottle body 1, an inner liner 2 is placed in the lower bottle body 1, a pump body 3 is installed on the upper end of the inner liner 2, a head cap 4 is connected to the upper end of the pump body 3, a nozzle 41 is provided at the front end of the head cap 4, a pressing sleeve 5 is fixedly connected to the upper end of the inner liner 2, an upper bottle body 6 is fixedly connected to the upper end of the lower bottle body 1, an outer sleeve 7 is connected to the outer sleeve 7 of the upper bottle body 6, the outer sleeve 7 has a through hole 71 which runs through from top to bottom and for the head cap 4 to pass through, a groove 72 with an opening facing upward and for the nozzle 41 to be inserted into the outer edge of the top of the outer sleeve 7, two inclined grooves 61 are distributed along the circumference of the upper side wall of the upper end of the upper bottle body 6, two protrusions 51 are distributed along the circumference of the middle outer wall of the pressing sleeve 5, the protrusion 51 passes through the inclined groove 61 and slides with the inclined groove 61.

[0020] like Figure 6 and Figure 7 As shown, in order to facilitate the rotation of the upper bottle body 6, an annular convex ring 62 is provided on the outer wall of the lower end of the upper bottle body 6, and a groove 73 is provided on the inner wall of the lower end of the outer sleeve 7. The convex ring 62 is inserted into the groove 73 and rotates with the groove 73.

[0021] The inner wall of the outer sleeve 7 is provided with two sliding grooves 74 extending up and down, and the ends of the protrusions 51 are inserted into the sliding grooves 74 .

[0022] like Figure 6 As shown, the lower end of the inclined slot 61 has a first horizontal locking slot 611, and the upper end of the inclined slot 61 has a second horizontal locking slot 612. The first horizontal locking slot 611 and the second horizontal locking slot 612 are used to lock the protrusion 51.

[0023] When the vacuum bottle is Figure 3 In the state, one hand holds the outer cover 7, and the other hand rotates the lower bottle body 1. The lower bottle body 1 rotates and drives the upper bottle body 6 to rotate. The protrusion 51 moves downward along the inclined groove 61. The protrusion 51 moves from Figure 4 The position of the state becomes Figure 2 The head cap 4 is retracted into the outer coat 7. Figure 1 When the head cap 4 needs to be extended again, the lower bottle body 1 can be rotated in the opposite direction.

[0024] The head cap retractable vacuum bottle provided by the utility model can retract the head cap 4 into the outer cover 7 when not in use, so the head cap 4 is not easily pressed by mistake when the vacuum bottle is placed in a bag.

[0025] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
