Detailed Description

In order to explain technical contents, structural features, and effects achieved by the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

As shown in fig. 1 and 2, the utility model discloses a fresh-keeping bottle 100 can be used to keep fresh fluid or liquid such as edible oil, soy sauce and flavouring, it includes bottle 1 and set up sealedly in bottle lid 2 on the bottleneck of bottle 1, bottle 1 has elasticity outer 11 and inelastic inlayer 12, elasticity outer 11 thickness is great, can automatic elasticity recover after pressing, inelastic inlayer 12 thickness is less, can not automatic elasticity recover after pressing. An air storage space 13 is arranged between the elastic outer layer 11 and the non-elastic inner layer 12, and the side wall of the elastic outer layer 11 is provided with a vent hole 11a which enables the air storage space 13 to be communicated with the outside; the cap 2 has an outlet passage 21, the outlet passage 21 being provided with a one-way outflow valve 22 to allow the fluid of the non-elastic inner layer 12 to flow from the inside to the outside and to prevent the inflow of air from the outside to the inside.

Referring to fig. 1, the one-way outflow valve 22 includes a sealing member 221 and an elastic member 222, and the elastic member 222 is connected to the sealing member 221 so that the sealing member 221 elastically presses against the outlet channel 21 inward. The bottle cap 2 is provided with a mounting seat 23, a mounting cavity 24 is arranged in the bottle cap 2, the mounting seat 23 is fixed in the mounting cavity 24, and the mounting seat 23 and the bottle cap 2 are of an integrally formed structure. The periphery of the mounting cavity 24 forms a flow passage and is communicated with the inner side and the outer side of the outlet channel 21. The sealing member 221 and the elastic member 222 are provided on the mounting seat 23. Specifically, the sealing member 221 is a sealing ball, and the elastic member 222 is a compression spring disposed between the sealing ball and the bottle cap 2, and the sealing ball is pressed against the inner side of the outlet channel 21. By providing the mounting seat 23, the sealing member 221 and the elastic member 222 can be mounted more securely and reliably, and the operation is more stable.

Referring to fig. 1, the bottle cap 2 is threadedly coupled to the bottle body 1. Therefore, the bottle body 1 and the bottle cap 2 can be mutually detached, so that the bottle body 1 can be cleaned when in an empty state, and the bottle cap 2 can be recycled. The bottle cap 25 is arranged on the outer side of the bottle cap 2, and the bottle cap 25 can be opened or covered on the outlet channel 21. The bottleneck cover 25 can prevent external microorganisms and impurities from entering the outlet channel 21, and effectively ensures that the outlet channel 21 and the one-way outflow valve 22 are clean.

As further shown in fig. 1, the upper end of the elastic outer layer 11 is fixedly connected to the upper end of the inelastic inner layer 12 by an MR glue layer 14. The inner bottom of the elastic outer layer 11 is fixedly connected with the outer bottom of the inelastic inner layer 12 through an MR glue layer 14. This ensures that the upper and lower ends of the inelastic inner layer 12 do not rattle against the elastic outer layer 11. The elastic outer layer 11 includes a first PP layer 111 and a second PP layer 112 disposed from outside to inside. The inelastic inner layer 12 includes an EVOH layer 121, a PP layer 122, and a PE layer 123 disposed from the outside to the inside. By providing the EVOH layer 121, the EVOH material is a gas impermeable material, and oxygen can be prevented from entering the inelastic inner layer 12, thereby further improving the freshness retaining performance of the freshness retaining bottle 100.

Referring to fig. 2, when fluid needs to be extruded, the bottle cap 25 is manually opened, then the bottle body 1 is pinched, the elastic outer layer 11 and the inelastic inner layer 12 of the bottle body 1 are compressed inward, at this time, the fluid in the inelastic inner layer 12 pushes the sealing ball under the pressure, and the sealing ball pushes the compression spring, so as to open the inner side of the outlet channel 21. At this time, the fluid can flow out of the outer side of the outlet channel 21 from the flow channels around the mounting cavity 24, and thus flows out to the outside. When the bottle body 1 is released by hand, the sealing ball is depressed again to the inside of the outlet passage 21 by the elastic force of the compression spring due to the internal fluid pressure loss, thereby sealing the internal space of the non-elastic inner layer 12 so that the non-elastic inner layer 12 is not expanded. At the same time, the elastic outer layer 11 is expanded outward by the elastic force, and at this time, the external air enters the air storage space 13 through the ventilation holes 11a until the elastic outer layer 11 is completely restored.

When the fluid in the bottle body 1 is less, the range of the force point of the hand is small, and the remaining fluid is difficult to be extruded, the vent hole 11a can be blocked by fingers, and then the elastic outer layer 11 is pressed, at this time, because the gas in the gas storage space 13 cannot be discharged from the vent hole 11a, and the volume of the gas storage space 13 is reduced by the pressing, the gas pressure in the gas storage space 13 is rapidly increased, so that the remaining fluid in the inelastic outer layer 11 is extruded.

Compared with the prior art, the utility model is provided with the elastic outer layer 11 and the inelastic inner layer 12, the elastic outer layer 11 can be elastically restored, and air can be sucked through the air holes 11a to generate air pressure on the inelastic inner layer 12; the non-elastic inner layer 12 can not be elastically restored and can not suck air, so that the oxidation of the fluid in the non-elastic inner layer can be prevented, and the aim of keeping fresh is fulfilled; a one-way outflow valve 22 is arranged on the bottle cap 2, so that the one-way outflow valve 22 only can allow the fluid of the non-elastic inner layer 12 to flow out from the inside to the outside when being opened and can prevent air from flowing in from the outside to the inside when being closed; because air can not enter the inside of the inelastic inner layer 12 from the outlet channel 21 at any time, the fluid of the inelastic inner layer 12 can be prevented from being oxidized, bacteria and microorganisms can be effectively prevented from entering the inside, the preservation time can be effectively prolonged, the preservation capacity can be improved, and the preservation time can be more than half a year.
