Description

Sterilization fresh bottle

Technical field:

Belong to food fresh-keeping vessel class in daily necessities, be specifically related to a kind of sterilization fresh bottle.

Background technology:

Existing food fresh-keeping vessel mostly is by the airtight method adding refrigeration to a certain degree, such as " happy button " crisper.Also someone attempts, by the method vacuumized, having certain effect.The former shortcoming is that fresh keeping time is short, and must by refrigerator.The latter's device complexity comparatively bothers.The short major cause of fresh keeping time is mixed into bacterium when loading food.

Utility model content:

For the problems referred to above, the thinking of this programme is: after food loads antistaling container, heat sterilization (being referred to as " sterilizing heating ") is carried out in sealing, and the bacterium be mixed into when killing loading, enters storage period after sterilizing, until no longer open before edible.Because the storage after sterilizing is all carried out under sterile sealing state, this germ-free condition can make the food fresh-keeping time longer.

Sterilizing heating is carried out in sealed states, and air pressure inside must increase, and too high meeting is dangerous, therefore must have blow off valve, again due to extraneous bacterium must be stoped to enter simultaneously, so blow off valve must be unidirectional, namely can only go out and can not enter.

In addition, due to sterilizing heat process exhaust tainer air major part discharge, after cooling because of in container without air, the food of loading is all rich in moisture, and interior pressure is similar to the saturated vapor pressure of water at normal temperature.This pressure is less than barometric pressure.This pressure reduction forms the thrust to bottle cap, causes bottle cap to be difficult to open.Therefore, must have air inlet function, namely first make when uncapping air enter in bottle, reach inside and outside air pressure balance, thus eliminate above-mentioned thrust, bottle cap is easy to open.

Above 2 is the designing requirement of this programme.

The structure of scheme of the present utility model transforms to form on existing glass preserving jar basis, adopt following structure: sterilization fresh bottle, comprise: bottle, bottle cap, clamp nut, multiplex valve seat, valve pocket, friction top, a packing seal between bottle and bottle cap, a packing seal of bottle cap and multiplex valve base chamber, screw by multiple screw thread between bottle and bottle cap, it is characterized in that: multiplex valve seat is installed on bottle cap mesopore, multiplex valve seat top is cone, its circular conical surface is provided with transverse holes, this transverse holes communicates with the hole of the vertical direction of multiplex valve seat, and in straight-through bottle, thus formation air extractor vent, valve pocket is circular cone annular silicon rubber valve pocket, and this silaatic valve pocket is tightly placed on the cone on multiplex valve seat top, can seal the collar extension of transverse holes, friction top covers on the cone on multiplex valve seat top, is connected with multiplex valve seat by STRTHD, and friction top is tapered sleeve form, and tapered sleeve tapering is identical with the tapering of multiplex valve body top cone, and tapered sleeve compresses valve pocket, seals the collar extension of transverse holes more reliably.

Wherein, the pressure that screw thread screws is equipped with suitable packing seal, is enough to block bacterium and invades, and the combination of this kind of structure and multipurpose valve is the simplest and the most direct, the mode easily that realize this technical goal.

The multipurpose valve of the bottle cap central design one-way when heating is not that (spring is easy to corrosion moist with having in the environment of salt by the spring pressure of general check valve and valve plug supporting with it, and not easy cleaning), this multiplex valve seat top is cone, on circular cone, cover has circular cone annular silicon rubber valve pocket to be close to it, it has suitable elasticity, air extractor vent can be compressed and ensure that extraneous gas can not enter, can ensure again and internal gas can be made to discharge when air pressure inside increases, realize one-way thus.When carrying out sterilizing heating, in bottle, the pressure of gas is greater than ambient atmosphere pressure Sandwich plate valve cover elasticity when giving birth to pressure sum, valve pocket makes internal gas overflow (can not install friction top during heating, otherwise gas cannot overflow) from valve pocket and spool faying face because of elastic deformation; When stopping heating, due to temperature decline gas in container pressure be less than ambient atmosphere pressure Sandwich plate valve cover elasticity give birth to pressure sum time, this pressure reduction can make valve pocket and spool centrum press tighter, and can not inwardly air inlet, and bacterium is also by outside the bottle refused.This structure not easily corrosion and be easy to cleaning.

Because valve pocket is that thin rubber is made, and when must ensure heating in bottle gas discharge smoothly, it is very large that its thrust can not design, and preserving bacterium time long can enter in bottle thus, designs friction top for this reason.Friction top connects with multiplex valve body by STRTHD.When screwing, bottle cap moves down, tapered sleeve in the middle part of it also moves down, tapered sleeve tapering is identical with the tapering of multiplex valve body top centrum, and tapered sleeve compresses valve pocket, shuts deflation hole more reliably, preserve during to ensure long, also can not leak gas when movement or strenuous vibration, more strictly block the passage that bacterium invades, thus improve the reliability of preservativity.Bottle selects corrosion-resistant steel or pottery, and object withstands heating.

The beneficial effects of the utility model are:

(1) preservativity is far above general crisper, is more than 1 week to more than 1 month and never degenerates.

(2) can not refrigerate, also can reach above effect.There is certain energy-conserving and environment-protective meaning.

Detailed description of the invention:

Embodiment 1:

The pressure that packing seal 1 and packing seal 24 all screw by respective threaded produces sealing effectiveness, is food grade silicon rubber both this with valve pocket 8 material.

Valve pocket 8 is tightly placed on the cone of multiplex valve seat 6 top, seals the collar extension of diameter 2 millimeters of circular holes cone leading to bottle inside, can block the path of gas and bacterium.

When carrying out sterilizing heating after bottle 1 loading food, bottle internal gas pressure rises, this air pressure exceedes external atmosphere pressure and valve pocket 8 elasticity when giving birth to pressure sum, because its elasticity must produce outside distortion (noting: must first remove friction top 7 before this operation), thus the larger gas of internal pressure must by overflowing, till internal and external pressure balance herein.Be heated to about 90 ~ 102 degrees Celsius, insulation appropriate time.Available normal domestic use steamer or pressure cooker " poach " heating, namely water boiling or pressure cooker are slowly vented is suitable temperature.Temperature retention time is depending on fresh-keeping requirement, and general tens minutes to half an hour.Friction top 7 can be screwed after sterilizing heating, complete fresh-keeping operation.

For the difficulty of directly uncapping that inside and outside differential pressure causes, the method for solution is: before uncapping, and first spins off friction top 7, takes valve pocket 8, and allow outside air flow in bottle, after inside and outside differential pressure disappears, bottle cap 2 can be easy to outward winding.This kind of structure solves one-way ventilating and the rear bottle cap of cooling in process in simple and direct mode simultaneously and not easily opens two problems.

Embodiment 2:

To some food such as pork braised in brown sauce, if just prepare part storage when manufacturing, multiple bottles of packing food materials, condiments and water can be adopted; first check that check valve air extractor vent is really unimpeded; first-class valve pocket 8, screws bottle cap 2, does not now go up friction top 7; then pressure cooker is put into; heating is started after adding suitable quantity of water, rear by normal method operation, about i.e. ripe truce after half an hour; afterwards etc. can open pressure cooker cover after safe opening, the bottled upper friction top 7 that preserve is screwed.This method contains manufacturing and fresh-keeping operation two parts of food, eliminates sterilizing and heats this step.
