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.
An embodiment of the present invention provides an embodiment of a double-layered bottle, and specifically refers to fig. 1 and fig. 2.
A double-layer bottle comprises a double-layer bottle body and a blocking cover 4 which is hermetically connected with a bottle mouth of the double-layer bottle body; the double-layer bottle body comprises a soft inner bottle body 1 and an outer bottle body 3 which can be extruded and can restore to the original shape after the extrusion is removed, a gap cavity 2 is formed between the inner bottle body 1 and the outer bottle body 3, and an opening is formed on one side of the bottle opening by the gap cavity 2; the blocking cover 4 comprises a top surface covering the bottle mouth and a side wall wrapping the bottle mouth, a one-way discharge hole communicated with the inner bottle body 1 is formed in the top surface, the side wall covers the opening of the gap cavity 2, a one-way sealing element 5 is arranged on the inner side of the side wall, the one-way sealing element 5 seals the opening when the outer bottle body 3 is extruded, and air is allowed to enter the gap cavity 2 in a one-way mode after the outer bottle body 3 is not extruded.
Specifically, the one-way sealing member 5 is a soft sealing member, the outer bottle body 3 includes a one-way abutting member 6, when the outer bottle body 3 is squeezed, the one-way sealing member 5 moves in a direction close to the one-way abutting member 6 and abuts against the one-way abutting member 6 to seal the opening, after the pressure for squeezing the outer bottle body 3 is released, the one-way sealing member 5 is separated from the one-way abutting member 6, and the opening allows air to enter the slit cavity 2 in one direction.
It should be noted that the one-way sealing member 5 is fixed on one side of the stop cover 4 close to the abutting member and is in a barb shape, and the one-way abutting member 6 is an abutting plate and is perpendicular to the sidewall of the outer bottle body 3.
It can be understood that when the outer bottle body 3 is squeezed, the air in the gap cavity 2 is squeezed to move towards the opening and squeeze the one-way sealing element 5, and the barb of the soft one-way sealing element 5 is squeezed to abut against the one-way abutting element 6, so that the opening is sealed; when unclamping the hand after, 3 reconversion of outer bottle, lead to the inside negative pressure of gap cavity 2, outside air can get into gap cavity 2, thereby extrude one-way sealing member 5 from the outside, the barb of one-way sealing member 5 resumes original barb state, no longer with 6 butts of one-way butt piece, the opening is beaten, outside air gets into gap cavity 2 rapidly, cause gap cavity 2 and outside pressure size to equal, extrude interior bottle 1 evenly, consequently interior bottle 1 can not form the negative pressure cavity, consequently outside air can not flow backward into in bottle 1, reached and prevented the effect in the bottle 1 in the air admission, the protection content is difficult rotten, thereby the shelf life of extension content.
Specifically, the one-way sealing member 5 is disposed to extend along a circumferential direction of the bottle wall of the outer bottle body 3.
It can be understood that, since the one-way abutment member 6 is abutted against the one-way sealing member 5 to seal the opening, the one-way abutment member 6 is disposed to extend along the circumferential direction of the bottle wall of the outer bottle body 3.
Specifically, the blocking cover 4 further comprises a buckle cover 10 for performing secondary protection on the discharge hole.
In this embodiment, a part of the fastening cover 10 is rotatably connected to the sidewall of the blocking cover 4 for opening or covering the fastening cover 10, so as to prevent the fastening cover 10 from being detached to be lost or from being contaminated by falling on the ground.
Specifically, the inner body 1 and the outer body 3 are provided with a fixing member 8 for preventing the inner body 1 from falling off from the outer body 3, and specifically, the blocking cap 4 is screw-coupled with the inner body 1.
The fixing member 8 may be a fixing point, and connects the inner bottle body 1 and the outer bottle body 3 by a point connection method, in this embodiment, the fixing member 8 is fixed at the bottle mouth of the outer bottle body 3, the fixing member 8 is a fixing plate vertically disposed on the sidewall of the bottle mouth of the outer bottle body 3, and a part of the fixing member 8 is fixedly connected to the bottom of the screw thread strip on the inner bottle body 1, and the structure is shown in fig. 2.
Specifically, the position of the blocking cover 4 close to the discharge hole comprises a flow guide part for guiding the material extruded from the discharge hole, and the flow guide part in the embodiment is in a hollow round table shape.
Specifically, a blocking piece 9 for preventing impurities from entering the flow guide piece is arranged on the buckle cover 10, the blocking piece 9 is in a long strip rod shape, one end of the blocking piece 9 is connected with the buckle cover 10, and the second end of the blocking piece extends perpendicular to the blocking cover 4.
In particular, the flap 4 is integrally formed with the one-way seal 5, and can be simply assembled or not assembled to reduce the assembly cost of the rear end. The existing scheme is that two check valves with opposite directions are manufactured on a blocking cover 4 to respectively guide contents and atmosphere to enter and exit from a bottle, but a precise mold needs to be developed in the manufacture of the check valve of the bottle cover, and the rear-section assembly process is complex and needs orientation, so that the cost is extremely high. Specifically, the blocking cover 4 is detachably connected with the inner bottle body 1.
In the embodiment, when the content in the double-layer bottle body needs to be used, the outer bottle body 3 is forcibly pressed, so that the air pressure in the gap cavity 2 is increased, the air flows towards the opening, the one-way sealing element 5 seals the opening, the bottle body is continuously pressed at the moment, the pressure in the gap cavity 2 is greater than the pressure in the inner bottle body 1, the inner bottle body 1 is pressed, the content is extruded from the discharge port, and when the inner bottle body 1 is pressed, all parts of the inner bottle body 1 are pressed by the air, and when the residual content is small, the residual content can be extruded; the one-way discharge port enables the content to be extruded, external air is not easy to enter the inner bottle body 1, namely the content is extruded, after the extrusion force for extruding the outer bottle body 3 is released, the outer bottle body 3 is recovered, the gap cavity 2 is in negative pressure, air outside the outer bottle body 3 rapidly enters the gap cavity 2, therefore, the air pressure in the gap cavity 2 outside the inner bottle body 1 is the same as the external air pressure, the inner bottle body 1 is uniformly extruded, the inner bottle body 1 cannot form a negative pressure cavity, external air cannot flow back into the inner bottle body 1, and the effect of preventing air from entering the inner bottle body 1 is achieved; through utilizing the sealed open-ended setting of gap cavity 2 and one-way sealing member 5 between inner bottle body 1 and the outer bottle body 3, simple structure, simple realization prevent that the air from getting into inner bottle body 1 and the effect that a small amount of content of surplus can be extruded easily, solved realize that the protection holds the inside content of jar, hold a small amount of content of jar surplus and be extruded easily and lead to the complicated technical problem of double-deck bottle structure.
While the invention 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 invention.
