Detailed Description
The embodiments described below are only a part of the embodiments of the present invention, and not all of them. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Embodiments of the present invention provide a low-cost double-layered bottle, and refer to fig. 1 to 4.
A low-cost double-layer bottle comprises a double-layer bottle body and a soft unidirectional membrane 3 hermetically connected with a bottle opening of the double-layer bottle body, wherein a unidirectional discharge hole 61 is formed in the unidirectional membrane 3; the double-layer bottle body comprises a soft inner bottle body 6 and an outer bottle body 5 which can be extruded and can be restored to the original shape after the extrusion is released, a gap cavity 7 is formed between the inner bottle body 6 and the outer bottle body 5, and a gap opening 4 is formed between the side surface of the inner bottle body 6 and the bottleneck of the outer bottle body 5; the bottle mouth of the inner bottle body 6 is wrapped with a soft bottle cap 2, the bottle cap 2 comprises a top surface 21 covering the bottle mouth of the inner bottle body 6 and a side wall wrapping the bottle mouth, the top surface 21 is provided with an opening corresponding to the one-way discharge hole 61 and an air inlet 22, the air inlet 22 is used for allowing outside air to enter the gap cavity 7 from the air inlet 22, and the one-way diaphragm 3 and the side wall of the bottle cap 2 form a one-way sealing valve; the one-way sealing valve is in a sealing state when the outer bottle body 5 is squeezed, and air is allowed to enter the slit cavity 7 from the air inlet 22 in one way after the squeezing of the outer bottle body 5 is released.
It should be noted that the bottle cap 2 is screwed 62 to the outer bottle body 5 near the edge of the slit opening 4, that is, a part of the sidewall of the bottle cap 2 is screwed to the outer bottle body 5, so as to achieve a sealed state, and thus, external air cannot enter from the joint of the outer bottle body 5 and the bottle cap 2.
Specifically, a groove is formed in the unidirectional diaphragm, and a concave part of the groove is communicated with the air inlet.
It should be noted that, in this embodiment, two grooves 31 are provided and located on the same side, and are distributed in an annular shape, and the opening of the recess 31 at the edge of the unidirectional membrane 3, which is recessed, is opposite to the air inlet 22, and when the air inlet 22 needs to intake air, the external air can more easily enter through the recessed space of the groove 31.
Specifically, the bottle cap 2 is in threaded connection with the inner bottle body 6, and a plurality of gaps are formed at the threads 62 on the inner bottle body 6 to form a plurality of air channels 621 for the external air to enter the gap cavity 7.
Referring to fig. 2, the air passage 621 is formed by a gap formed by a broken thread. Air passage 621
Specifically, the diameter of the one-way membrane 3 is larger than that of the mouth of the inner bottle body 6, and when the one-way membrane is extruded, the pressure at the one-way discharge hole 61 of the inner bottle body 6 is increased, so that the contents are extruded more easily, and the labor is saved; when the outer bottle body 5 is squeezed, the one-way diaphragm 3 is tightly pressed against the thread 62 on the inner bottle body 6 to prevent the outside air from entering the air passage 621 and the gap cavity 7. It will be appreciated that the unidirectional diaphragm 3 is sealed by abutment at its own edge with the projecting screw thread 62. It should be noted that when the outer bottle body 5 is squeezed, the inside of the inner bottle body 6 is in a negative pressure state relative to the inside of the slit cavity 7, the inner bottle body 6 is squeezed by pressure from all sides, and the one-way diaphragm 3 moves toward the direction connected with the raised screw thread 62 to achieve the sealing effect.
The inner bottle body 6 is provided with a plurality of first recesses 63 at a side thereof adjacent to the slit opening 4 for allowing air at the air passage 621 to enter the slit cavity 7. Specifically, the bottle cap 2 further comprises a buckle cover 1 for performing secondary protection on the one-way discharge hole 61. In this embodiment, the fastening cover 1 is rotatably connected to the sidewall of the blocking cover, and is used to open or cover the fastening cover 1, so as to prevent the fastening cover 1 from being detached to be lost or falling to the ground to be polluted.
Specifically, the side wall of the bottle cap 2, the inner bottle body 6 and the outer bottle body 5 can be detachably connected with each other, and when one of the side wall and the inner bottle body is damaged, the undamaged side wall and the undamaged side wall can be reassembled, so that the utilization rate can be improved.
Specifically, the bottle cap 2 includes a flow guide member for guiding the content extruded from the one-way discharge port 61 at a position close to the one-way discharge port 61, and the flow guide member in this embodiment is in a hollow circular truncated cone shape with an opening at one end.
Specifically, a blocking piece 12 for preventing impurities from entering the flow guide piece is arranged on the buckle cover 1, the blocking piece 12 is in a long strip rod shape, one end of the blocking piece 12 is connected with the buckle cover 1, the second end of the blocking piece extends perpendicular to the buckle cover, and when the buckle cover 1 is buckled down, the blocking piece 12 is inserted into the opening of the flow guide piece and blocks the one-way discharge hole 61.
Specifically, the inner diameter of the inner bottle body 6 near the one-way discharge hole 61 is larger than the inner diameter of the inner bottle body 6 and the outer bottle body 5 at the position of the gap cavity 7.
In this embodiment, when the contents in the double-layered bottle body are required to be used, the outer bottle body 5 is forcibly pressed to increase the air pressure in the gap cavity 7, the air pressure in the inner bottle body 6 is lower than the air pressure in the outer bottle body 5, the inner bottle body 6 is pressed, and the contents are extruded from the one-way discharge port 61 of the inner bottle body 6, meanwhile, the one-way sealing valve plays a role in sealing, so that the external air cannot enter from the air inlet 22, and the inner bottle body 6 is continuously pressed; the content is continuously extruded, after the extrusion force for extruding the outer bottle body 5 is released, the outer bottle body 5 is recovered, the one-way sealing valve is not sealed at this time, the air outside the outer bottle body 5 rapidly enters the gap cavity 7 from the air inlet, so that the air pressure in the gap cavity 7 outside the inner bottle body 6 is the same as the external air pressure, and the inner bottle body 6 is rapidly and uniformly extruded, therefore, the inner bottle body 6 cannot form a negative pressure cavity, the external air cannot flow back into the inner bottle body 6, and the effect of preventing the air from entering the inner bottle body 6 is achieved; two one-way sealing valves are arranged among the bottle cap 2, the inner bottle body 6 and the outer bottle body 5 by arranging one-way sealing valve between the inner bottle body 6 and the bottle cap 2 without arranging a complex structure; the double-layer bottle is simple in structure, so that the bottle cap 2 and the inner bottle outer body 5 can be used after being simply assembled, and the production cost is reduced.
In the present embodiment, when the outer body 5 is pressed: the one-way diaphragm 3 moves to the protruding screw thread 62 department of being close to screw thread 62 until the butt, and the content of inner bottle body 6 is extruded, and when unclamping the hand, outer bottle body 5 reconversion, the outside air gets into from air inlet 22, and the cavity department that forms from air passage 621 on the screw thread 62 passes through the back, gets into gap cavity 7 through first sunken 63 again to make the better reconversion of outer bottle body 5.
While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the utility model.
