Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic packaging bottles, in particular to a soft-shell vacuum squeeze bottle. Background Art

[0002] In the field of cosmetic packaging, most existing cosmetic bottles for lotions and creams generally include a shell, which contains a container for containing the cosmetics. A pump head is located at the opening of the container to pump out the cosmetics inside. During use, the pump head is squeezed to release the contents. Due to the need for a pump head, the manufacturing cost of these cosmetic bottles is relatively high. Of course, there are also soft-shell packaging options that squeeze the outer soft shell to squeeze out the cosmetics inside. However, when the internal cosmetic volume is low, these soft-shell packaging requires almost completely flattening the soft shell to continue squeezing out the cosmetics, which is inconvenient to use and can leave a lot of residue. Summary of the Invention

[0003] The utility model addresses the deficiencies of the existing technology and provides a soft-shell vacuum squeeze bottle, which can squeeze out the cosmetics inside by squeezing the soft shell, and can squeeze out the cosmetics by light pressure even when there is little remaining cosmetics, and the residual amount is small.

[0004] In order to solve the above technical problems, the present invention solves the problem through the following technical solutions: a soft-shell vacuum squeeze bottle, comprising a soft shell, the opening side of the soft shell is sealed with a shoulder sleeve, the shoulder sleeve and the soft shell form a accommodating cavity, a flexible storage bag is arranged in the accommodating cavity, a first through hole is provided on the shoulder sleeve, the discharge port of the flexible storage bag passes through the first through hole, a one-way liquid outlet valve is provided in the discharge port, and a one-way air inlet valve connected to the accommodating cavity is provided on the shoulder sleeve. When the soft shell of this soft-shell vacuum squeeze bottle is pressed, the accommodating cavity is sealed, and when the soft shell is compressed, the flexible storage capsule is also subjected to corresponding pressure, and the cosmetics in the flexible storage capsule are squeezed out from the discharge port. When the soft shell is restored by its own elastic force, air is taken in from the one-way air inlet, and the gap between the flexible storage capsule and the inner wall of the accommodating cavity is filled with air. Since the flexible storage capsule is provided with a one-way air inlet valve at the discharge port, it no longer expands after being compressed. When pressed next time, light pressure can be used to allow the flexible storage capsule to quickly squeeze out the cosmetics again. Moreover, since the flexible storage capsule can be almost completely contracted, the residual amount is small.

[0005] In the above technical solution, preferably, a first limiting ring is provided on the outer periphery of the discharge port, a positioning sleeve is fastened and connected to the shoulder sleeve, a second through-hole is provided on the positioning sleeve, a flow guide is sandwiched between the shoulder sleeve and the positioning sleeve, the flow guide squeezes the first limiting ring against the edge of the first through-hole, a flow guide tube is provided on the flow guide, one end of the flow guide tube is connected to the discharge port, and the other end of the flow guide tube is passed through the second through-hole. This structure can conveniently position the flexible storage bag on the shoulder sleeve, and due to the pressure of the flow guide on the first limiting ring, the sealing performance of the connection between the flow guide and the discharge port can be improved.

[0006] In the above technical solution, preferably, the shoulder sleeve is provided with a plurality of elastic support ribs around the first through hole, the elastic support ribs being bent and extending toward the side of the positioning sleeve, and the elastic support ribs being abutted against the first limiting ring. The provision of the elastic support ribs can provide a certain elastic support force, further improving the sealing performance of the connection between the flow guide and the discharge port. Moreover, because the elastic support ribs are easily expanded, the flexible storage bag can be more conveniently loaded into the accommodating cavity.

[0007] In the above technical solution, preferably, the one-way liquid outlet valve is provided with a second limiting ring, which is clamped between the flow guide and the discharge port. This structure facilitates the positioning of the one-way liquid outlet valve.

[0008] In the above technical solution, preferably, a support rod is provided at the bottom of the one-way liquid outlet valve, extending into the flexible storage bladder, to prevent the flexible storage bladder from abutting against each other at the entrance of the discharge port. This structure is used to prevent the opposing side walls of the flexible storage bladder from abutting against each other at the entrance of the discharge port, thereby hindering the extrusion of cosmetics.

[0009] In the above technical solution, preferably, two support rods are provided and arranged opposite to each other. This structure makes it less likely that the opposite side walls of the flexible storage bag will adhere to each other at the entrance of the discharge port, and has almost no effect on the amount of cosmetics remaining in the flexible storage bag.

[0010] In the above technical solution, preferably, the one-way liquid outlet valve includes a first cylindrical valve housing, a first support platform is provided within the first valve housing, a material passage hole and a first positioning hole are axially provided on the first support platform, a first elastic member is fixed in the first positioning hole, and a first elastic sealing cover is provided at one end of the first elastic member, and the first elastic sealing cover is closely attached to the material passage hole. This one-way liquid outlet valve has a simple structure, is easy to install, and is low in cost.

[0011] In the above technical solution, preferably, the one-way air intake valve includes a second cylindrical valve housing, a second support platform disposed within the second valve housing, a vent hole and a second positioning hole axially disposed on the second support platform, a second elastic member secured within the second positioning hole, a second elastic sealing cover disposed at one end of the second elastic member, the second elastic sealing cover closely attached to the vent hole. This one-way air intake valve has a simple structure, is easy to install, and is low in cost.

[0012] In the above technical solution, preferably, the shoulder cover and the soft shell are fastened together by an annular groove and an annular protrusion, and a sealing ring is sandwiched between the shoulder cover and the soft shell. This structure is used to improve the sealing between the shoulder cover and the soft shell.

[0013] Compared with the prior art, the present invention has the following beneficial effects: when the soft shell of the soft-shell vacuum squeeze bottle is pressed, due to the sealing of the accommodating cavity, when the soft shell is compressed, the flexible storage capsule is also subjected to corresponding pressure, and the cosmetics in the flexible storage capsule are squeezed out from the discharge port; when the soft shell is reset by its own elastic force, air is taken in from the one-way air inlet, and the gap between the flexible storage capsule and the inner wall of the accommodating cavity is filled with air; and since the flexible storage capsule is provided with a one-way air inlet valve at the discharge port, it no longer expands after being compressed, and when pressed next time, the flexible storage capsule can be quickly squeezed out of the cosmetics again by still light pressure; and since the flexible storage capsule can be almost completely contracted, the residual amount is small.

[0019] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments: Figures 1 to 5A soft-shell vacuum squeeze bottle includes a soft shell 1, an opening side of the soft shell 1 is sealed with a shoulder sleeve 2, the shoulder sleeve 2 and the soft shell 1 form a accommodating cavity 3, a flexible storage bag 4 is provided in the accommodating cavity 3, the flexible storage bag 4 is used to store cosmetics, a first through hole 5 is provided on the shoulder sleeve 2, a discharge port 6 of the flexible storage bag 4 passes through the first through hole 5, a one-way liquid outlet valve 7 is provided in the discharge port 6, and a one-way air inlet valve 8 connected to the accommodating cavity 3 is provided on the shoulder sleeve 2. When the soft shell 1 of this soft-shell vacuum squeeze bottle is pressed, since the accommodating cavity 3 is sealed, when the soft shell 1 is compressed, the flexible storage capsule 4 is also subjected to corresponding pressure, and the cosmetics in the flexible storage capsule 4 are squeezed out from the discharge port 6. When the soft shell 1 is reset by its own elastic force, air is taken in from the one-way air inlet, and the gap between the flexible storage capsule 4 and the inner wall of the accommodating cavity 3 is filled with air. Since the flexible storage capsule 4 is provided with a one-way air inlet valve 8 at the discharge port 6, it no longer expands after being compressed. When pressed next time, light pressure can be used to allow the flexible storage capsule 4 to quickly squeeze out the cosmetics again. And since the flexible storage capsule 4 can be almost completely contracted, the residual amount is small.

[0020] In this embodiment, a first limiting ring 9 is provided on the outer periphery of the discharge port 6, a positioning sleeve 10 is fastened and connected to the shoulder sleeve 2, a second through hole 11 is provided on the positioning sleeve 10, a flow guide 12 is sandwiched between the shoulder sleeve 2 and the positioning sleeve 10, the flow guide 12 squeezes the first limiting ring 9 against the edge of the first through hole 5, and a flow guide tube 13 is provided on the flow guide 12, one end of the flow guide tube 13 is connected to the discharge port 6, and the other end of the flow guide tube 13 is passed through the second through hole 11.

This one-way liquid outlet valve 7 is simple in structure, easy to install, and low in cost.

[0026] In this embodiment, the one-way air intake valve 8 includes a second, cylindrical valve housing 23, within which a second support platform 24 is disposed. A vent hole 25 and a second positioning hole 26 are axially disposed on the second support platform 24. A second elastic member 27 is secured within the second positioning hole 26. A second elastic sealing cover 28 is disposed at one end of the second elastic member 27. A stopper larger than the second positioning hole 26 is disposed at the other end of the second elastic member 27. The second elastic sealing cover 28 is closely attached to the vent hole 25. This one-way air intake valve 8 is simple in structure, easy to install, and inexpensive. The valve housing of the one-way air intake valve 8 is integrally formed with the shoulder sleeve 2.

[0027] In this embodiment, in order to improve the sealing between the shoulder sleeve 2 and the soft shell 1, the shoulder sleeve 2 and the soft shell 1 are fastened and fixed by an annular groove and an annular protrusion, and a sealing ring 29 is sandwiched between the shoulder sleeve 2 and the soft shell 1.
