Abstract

The invention relates to a novel packaging box. For a packaging box for a common fluid product, after the product is extruded out, part of air or part of extruded product is sucked into the box due to internal and external pressure difference of the packaging box while a great amount of microorganisms exist outside, so that the product is possibly polluted or even is rotted and deteriorated. Moreover, the common plastic packaging box has unfixed extrusion amount for each time, so that if the product is excessively extruded, waste is caused; and if the product is insufficiently extruded, the packaging box needs to be squeezed repeatedly and the operation is fussy. The packaging box which the invention relates to can prevent the air or the extruded product from being sucked back into the box to pollute the product in the box and can also simply control the amount of the extruded product for each time so as to bring convenience to use of the product.

Description

A kind of packing box

Technical field

This patent is the patent about a kind of packing box.

Background technology

The packing box of general packing fluid product, after product was extruded, the product because the packing box external and internal pressure is poor with part air and the contacted external world sucked in the box.Yet a lot of microbes in the product in air and the contacted external world cause in the box product contaminated even putrid and deteriorated.In addition, the general each extrusion capacity of packing box is unfixing, sometimes extrudes and too much causes waste; Sometimes extrude repeatedly extrusion operation of very few needs, waste time.

Summary of the invention

The related a kind of packing box of this patent can prevent that air or the outer product of extrusion box from being entered in the box by suck-back, can control simply the product volume of at every turn extruding simultaneously, thereby bring convenience to the user.

The related packing box of this patent is comprised of box main body (" 1 " part among Fig. 1) and device (" 2 " part among Fig. 1) and some attaching partss of controlling each extrusion capacity.Box main body (" 1 " part among Fig. 1) is made by the softer material of material, like this can be so that the difference of pressure inside and outside the packing box be little behind the extruded product, and the strength of suck-back is little.The device (" 2 " part among Fig. 1) that prevents suck-back and control an extrusion capacity is separately installed with by elasticity tubing two ends and allows fluid to form to two one-way cocks (" 3,4 " part among Fig. 1) that same direction flows.These two valves are made by soft valve or hard material.Volume between two valves slightly equals the maxim of each extrusion capacity.When pressing two elasticity tubing (" 5 " part among Fig. 1) between the valve, the one-way cock in the outside is opened at every turn, inboard one-way cock closure, and flow goes out loading cartridge; After unclamping hand, the one-way cock closure in front, the one-way cock in back is opened, and fluid flows into loading cartridge, finishes and once pushes the feeding operation.

Description of drawings:

Fig. 1: a kind of section-drawing of packing box." 1 " is the packing box main body among the figure, is made by soft material." 2 " are the device that prevents suck-back and control an extrusion capacity among the figure.

Fig. 2: prevent suck-back and control the section-drawing of the device of an extrusion capacity.The device that prevents suck-back and control an extrusion capacity is comprised of " 3 ", " 4 ", " 5 " three parts." 3 " and " 4 " for allowing the valve of fluid one-way trip, is the one-way cock that the valve done of soft material or hard material are done." 5 " are resilient tubing.

The specific embodiment:

1, will prevent that suck-back and the device of controlling an extrusion capacity directly are installed on the packing box exit.

2, will prevent that suck-back and the device of controlling an extrusion capacity are connected to the packing box exit by the certain-length pipeline.

Claims

1. packing box is characterized in that being equipped with or pipeline by certain-length is connected with a kind of device that prevents suck-back and control an extrusion capacity in the packing box main body.

2. based on a kind of packing box of claim 1, it is characterized in that there is the device that can prevent suck-back and can control an extrusion capacity in the exit of packing box.

3. based on a kind of packing box of claim 1, it is characterized in that the packing box exit prevent suck-back and control the device of an extrusion capacity and the packing box main body be an integral body or install, or link together by pipeline.

4. based on a kind of device that prevents suck-back and control an extrusion capacity of claim 1, it is characterized in that being formed by an elasticity tubing and the outside one-way cock of both direction.

5. based on a kind of device that prevents suck-back and control an extrusion capacity of claim 1, the elasticity tubing that it is characterized in that forming this device is regular tubing or other irregular tubing such as pipe, square tube.

6. based on a kind of device that prevents suck-back and control an extrusion capacity of claim 1, two one-way cocks that it is characterized in that forming this device are that one-way cock or the bi-material that the valve made of soft material or hard material are made united the one-way cock of making.
