Summary of the invention
Problems to be solved by the invention
Therefore, the purpose of the present invention is to provide can kept for any time being inverted or almost during inversion fast in container
The thick substances small volume containers of sticky content are discharged fastly.
The solution to the problem
It is 300ml below for accommodating the small volume containers of thick substances that the present invention, which provides capacity,.Container includes main body
Portion, the inner surface of the main part is provided with the region for being used to rapidly be discharged content when keeping and being inverted container, and uses
In the region that content is slowly discharged.
Thick substances of the invention depend on being formed on the inner surface of main part for rapidly arranging with small volume containers
The means in the region of content and the region for content to be slowly discharged out can be divided into odd-shaped cross section type (odd-
Shaped cross section type), liquid film forming type and exudative type.
(1) odd-shaped cross section type thick substances have main part with small volume containers, and the inner surface of main part has
The special-shaped longitudinal cross-section of asymmetrically shape, to be formed for the region of content to be rapidly discharged and for content to be slowly discharged
The region of object.
(2) liquid film type thick substances small volume containers have main part, and the inner surface of main part has improvement pair
In the liquid film of the lubricating fluid of the landing of thick substances.When observing on the cross section of the main part of container, liquid film is in circumference
There is non-uniform thickness on direction, and formed by the non-uniform thickness of liquid film for content to be rapidly discharged
Region and region for content to be slowly discharged.
(3) exudative type thick substances have multilayered structure with small volume containers comprising form containing for the inner surface of container
The resin layer of lubricant, when observing on the cross section of the main part of container, the resin layer containing lubricant is in a circumferential direction
It is formed with non-uniform thickness, and by the non-uniform thickness of the resin layer containing lubricant in rapidly discharge
Tolerant region and the region for content to be slowly discharged.

Specific embodiment
As described above, thick substances according to the present invention are with small volume containers according to for the shape on the inner surface of main part
At the means in the region for content to be rapidly discharged and the region for content to be slowly discharged, abnormity can be divided into and cut
Face type, liquid film forming type and exudative type.
Fig. 1 shows the embodiment party of the odd-shaped cross section type thick substances small volume containers of the invention in inversion state
Case.Container includes hollow tube-shape main part 1, wherein outlet of the one end of neck 3 as content, and the other end is by bottom 5
Closing.
On the outer surface of neck 3, screw thread 7 can be formed with cap sealing container, although this depends on implementation of container
Scheme.
The inner capacities of thick substances small volume containers be 300ml or less, particularly, 150ml or less.Since low capacity holds
Device is light-weight, as shown in Figure 1, can be kept being inverted or being almost inverted so that content is discharged.This can often make content
Discharge is difficult.On the other hand, large-rolume container is heavy and usually has handle, can not be kept being inverted or being almost inverted,
And it there is no problem in terms of content discharge property.Therefore, herein by following liquid film types or the capacity of exudative type container
It is set as 300ml or less, particularly 150ml or less.
In the present invention, particularly importantly as shown in (a) of Fig. 1, the inner surface of main part 1 has asymmetric lubrication
Property.That is, the inner surface with uneven lubricity is different in terms of the speed of fall of content.For example, (a) in Fig. 1 is shown
Example in, the side of main part 1 inner surface 1a have biggish lubricity, and the inner surface 1b of opposite side have compared with
Small lubricity.As a result, content 10 falls faster on inner surface 1a, and fall slower on inner surface 1b.
On the other hand, conventionally known small volume containers along the circumferential direction have uniform profit usually on inner surface of container
Slip.
That is, content 10 is along main part 1 when keeping being inverted so that content 10 is discharged by the container as shown in Figure 2
Inner surface is equably fallen, and can be limited in inside container before the opening for reaching neck 3.In this state, air
Layer 13 is limited between content 10 and bottom 5.Since atmospheric pressure is greater than the pressure applied by air layer 13, content
10 are limited in container and its discharge will be difficult.
In contrast, in the present invention, as shown in (a) of Fig. 1, landing property is asymmetrically assigned, thus in main part 1
The position for keeping the speed of fall of content different is formed on inner surface.This leads to the difference of the speed of fall of content 10, therefore,
The side that air layer 13 between content 10 and bottom 5 can reduce along the thickness of content 10 is (that is, have lesser fall
The side 1b of lower speed) easily escape.The shortcomings that content 10 for being difficult to be discharged limitation in a reservoir can be effectively avoided in this.
In the present invention, the embodiment above with asymmetric landing property is not particularly limited, as long as content 10
Speed of fall it is different.As long as (being used that is, forming the region that content 10 is rapidly fallen on the inner surface of main part 1
In rapidly be discharged content 10 region) and content 10 slowly fall region (for slowly discharge content 10
Region), then be not particularly limited.
In the embodiment shown in (a) of Fig. 1, the region 1a and content 10 that content 10 is rapidly fallen are slowly
The region 1b fallen is in relative position.The present invention is not limited to the embodiment, region 1a and 1b be may be at each other
Close position.
Above-mentioned odd-shaped cross section type thick substances small volume containers can be any suitable by such as plastics, glass and metal etc.
Material is formed, as long as it meets the requirement that its inner surface in principle has lubricity variation.From the viewpoint convenient for forming, hold
Device is preferably made from plastic.
Although the shape to container is not particularly limited, it is preferred that being with hollow shape by container forming.It is optimal
Choosing, container has the shape of the bottle or pipe that are provided with the opening for content to be discharged, and the diameter being open is less than appearance
Receive content main part section diameter.Meanwhile about wide open container or cup, the opening for content to be discharged has
There is the section bigger than its main part.It there is no the necessary discharge for considering content 10 in the container of the type.
For example, blow-molded container shown in Fig. 1 can be replaced with tubular container.
Fig. 3 shows the schematic cross section of the main part 1 of liquid film type small volume containers.
Different from container shown in FIG. 1, the container in Fig. 3 has the liquid film 21 being formed on the inner surface of main part 1.
The liquid film 21 assigns the landing for sticky content 10 (being not shown in Fig. 3).Change that is, the liquid for forming liquid film 21 is used as
The lubricating fluid of the kind landing for content 10.
As shown in figure 3, the liquid film 21 formed on the inner surface of the main part of container 1 in the present invention has in a circumferential direction
There is non-uniform thickness.Specifically, the region in region and lesser thickness t of the liquid film 21 with biggish thickness T.With larger
Thickness T region and region with thickness t respectively along the band-like extension of the axis direction of container.As a result, in the area with thickness T
In domain, content 10 is rapidly discharged with high slip velocity.On the other hand, slip velocity subtracts on the region with thickness t
It is small, so that the velocity of discharge as shown in (a) of Fig. 1 has variation.Therefore, sticky content 10 flows into the area for accelerating slip velocity
Domain, and its thickness reduces on the region for reducing slip velocity.This make the air layer 13 between content 10 and bottom 5 from
The thin region of content 10 (side that liquid film 21 has lesser thickness t) easily escapes, to be effectively prevented from the row of being difficult to
The shortcomings that limiting sticky content 10 in a reservoir out.
Depending on accommodating the type of content 10 in a reservoir, from unmixing with content 10 and be non-volatile
Selection is used to form the liquid (lubricating fluid) of above-mentioned liquid film 21 in the liquid of (for example, boiling point is 200 DEG C or more).And it is required that liquid
Body shows the repellency to content 10.Its representative example includes edible oil (animal tallow or vegetable oil), fatty acid glycerine
Three esters, fluorinated surfactant, atoleine and silicone oil.Lubricating fluid can be selected from these according to the type of content 10.
Above-mentioned liquid film type small volume containers are typically used as the plastic containers with the inner surface of resin.By with such as olefin-based
The thermoplastic resins such as resin and polyester (especially olefin-based resin) form inner surface of container, can stably keep lubricating fluid
Liquid film 21.
Preferably, it is similar to odd-shaped cross section type container shown in Fig. 1, which is for the opening of content to be discharged
The lesser bottle of diameter or pipe.
For example, the liquid film 21 with above-mentioned thickness distribution can be formed by spraying.Specifically, forming containers it
Afterwards, lubricating fluid is sprayed on an internal surface of the container to form liquid film 21.At this point, nozzle is directed toward the increased area of thickness of liquid film 21
Domain.In this manner, the liquid film 21 with thickness distribution can be readily formed.
In such a case it is possible to carry out laboratory test in advance to determine spraying conditions (spray pressure and amount), to set
Determine the thickness distribution of liquid film 21 and prevent the blocking of content 10 etc..
It, can also be by using the method for forming the resin layer containing lubricant for exudative type small volume containers as described below
To form the liquid film 21 with thickness distribution.

Different from Fig. 1 and container shown in Fig. 3, the container in Fig. 4 has the inner surface of main part 1 by resin containing lubricant
The structure that layer 23 is formed.The lubricant is oozed out on an internal surface to contact with sticky content 10 (being not shown in Fig. 4), thus
Assign the landing for sticky content 10.In other words, the profit in the resin layer containing lubricant 23 of inner surface of container is formed
Lubrication prescription (lubricant) is used as the lubricity reagent (lubricating agent) for improving the landing for content 10.
In the exudative type small volume containers, liquid film type small volume containers as shown in Figure 3, as shown in (a) of Fig. 4,
Resin layer containing lubricant 23 has thickness distribution.That is, resin layer containing lubricant 23 is with the region of biggish thickness T and lesser
The region of thickness t.Region with biggish thickness T and the region with lesser thickness t are respectively along the axis direction band of container
Shape extends.In the region with biggish thickness T, larger amount of lubricant is oozed out on the surface of resin layer, which increase
For the slip velocity of content 10.In the region with lesser thickness t, small amount of lubricant oozes out into resin layer
On surface, it reduce the slip velocities for content 10.When by the container upside down, is formed and arranged as shown in (a) of Fig. 1
VELOCITY DISTRIBUTION out.That is, the air for being present in container bottom is easy from the region that resin layer containing lubricant 23 has lesser thickness t
Evolution.This can be effectively prevented the shortcomings that sticky content 10 for being difficult to be discharged limitation in a reservoir.
In (b) of Fig. 4, resin layer containing lubricant 23 has uniform thickness, but the profit being blended in resin layer 23
The measurer of lubrication prescription has concentration distribution.For example, larger amount of lubricant is blended in the 23a of region.Blending has larger amount of lubricant
Region 23a along container the band-like extension of axis direction.Similarly, in this embodiment, larger amount of lubricant is being blended
Region 23a on for content 10 slip velocity increase, therefore, when container upside down, occur as shown in (a) of Fig. 1
Velocity of discharge distribution.That is, the air for being present in container bottom is easy from the region of small amount of lubricant is blended (except region 23a
Region in addition) evolution.This can be effectively prevented the shortcomings that sticky content 10 for being difficult to be discharged limitation in a reservoir.
In the embodiment shown in (b) such as Fig. 4, the concentration of lubricant can be formed in resin layer containing lubricant 23
It is distributed to form the slip velocity distribution for escaping air from the inverted container of holding.That is, lubricant can be only blended in
Without being blended in other regions in the 23a of region.
In the present invention, select lubricant depending on the type of content so that it due to from resin layer 23 exudation and
Display improves the effect of the landing for sticky content.The representative example of lubricant is described below.
(a) hydro carbons reagent, such as Liquid Paraffin, natural paraffin wax or synthesis paraffin, microwax, polyethylene wax and chlorination are poly-
Ethylene waxes；
(b) fatty acid, such as stearic acid and lauric acid；
(c) fatty acyl amide, such as stearic amide, palmitamide, oleamide, erucyl amide, di-2-ethylhexylphosphine oxide are hard
