The specific embodiment

In the existing flexible pipe container that pumping plant is installed, because pumping plant also is installed in from the mouth neck portion of the outstanding mouthpiece that is set up in end of tubular flexible pipe by link, the outstanding part of shape flexible pipe can become big so conform to the principle of simplicity, be difficult to seek the miniaturization of container, and, be easy to become the design model of lack of balance.

In addition, because pumping plant generally is to be formed by the relatively poor polyolefin resin of oxygen shielding etc., so will be owing to oxidation easily the content of deterioration be contained under the situation about using in the cylindrical container with flexual sheeting, because inflow via the oxygen of pumping plant, therefore particularly in the process of the circulation before the use of cylindrical container etc., be necessary to make contents that deterioration does not take place.

Will be owing to oxidation the content (for example hair dye) of deterioration be contained under the situation in the container of such band pump, though be necessary to give the integral container that comprises pumping plant with the oxygen shielding, but, as previously discussed, because pumping plant generally is to be formed by relatively poor polyolefin resin of oxygen shielding etc., so need work hard at the aspects such as a part that form pumping plant by parts, thereby might make cost uprise (problem 1) with oxygen shielding.

Therefore, considered the oxygen shielding is only given flexible pipe container and pumping plant is installed in such flexible pipe container when in use, but, the man-hour that needs cost to install, in addition, by making flexible pipe container and pumping plant be respectively different individualities, thereby the packaging and storing thing that holds the box etc. of flexible pipe container before use in advance necessitates, thereby exists the size of product (container of band pump) as a whole to become big problem (problem 2).

Above-described problem also is present in the situation that is necessary the gas-barrier property except the oxygen shielding is given pumping plant, in addition, also is present in the container except flexible pipe container, also is present in the pumping plant that can be separated with container body and constitute.

On the other hand, as the twin of just can from 2 containers that are arranged side by side, spue respectively with single job the 1st medicament and the 2nd medicament container that spues, knownly will be installed on the twin that is arranged side by side 2 aerosol containers spue (for example with reference to TOHKEMY 2000-297018 communique) in the container with the operating unit that single job just can be depressed control lever.

; in the twin that is arranged side by side 2 aerosol containers spues container, there is following problem: because container is an aerosol container, so manufacturing cost is higher; gas in the container must be drained and the trouble that becomes when discarded, and the comparatively difficulty that quantitatively spues of content.

In addition, the known twin that the box parts that hold 2 container bodies that are arranged side by side can freely be loaded and unloaded on the substrate parts that possesses 2 pumps and the constitute container (for example with reference to TOHKEMY 2002-2757 communique) that spues.

But, in the twin that TOHKEMY 2002-2757 communique is put down in writing spues container, because the quantity of its component parts is more, thereby cost is uprised, and is taking the time aspect the assembling of component parts.

The content of container aerosol container is a heavy body if the twin that such 2 aerosol containers by being arranged side by side of being put down in writing in TOHKEMY 2002-119328 communique constitute spues, the easy generation problem that spues of content so, not easy to operate, thereby be used mainly as being used for the spuing container of low-viscosity content.

On the other hand, as the container that spues that holds full-bodied content, be extensive use of the container of band pump.Even the twin that such container by 2 band pumps that are arranged side by side of putting down in writing constitutes in TOHKEMY 2006-306478 communique spues in the container, the container of band pump also trends towards the container that spues as the heavy body content, and the situation that is envisioned for full-bodied content is also a lot.

, in twin spues container, be that hair dye ingredient and the 2nd medicament are that the 1st medicament and the 2nd medicament can not spued on appropriate opportunity under the situation of hair dye of bi-component medicament formula of oxidizer for example holding the 1st medicament.

That is, existing hair dye is to design as prerequisite with 2 medicaments that spue simultaneously, still, in general, because the viscosity of viscosity ratio the 1st medicament of the 2nd medicament is low, so if use the existing twin container that spues as before, the 2nd medicament will be spued earlier so.Yet, preferred according to the design of product, to dye since the 1st medicament into the mode that reacts to hair the 1st medicament that spues earlier.

The present invention relates to easily to seek the cylindrical container of band pump of the miniaturization of integral container.In addition, under the situation of holding the content that deterioration takes place easily owing to oxidation, also can avoid the cylindrical container of the band pump of the deterioration of content in the processes such as circulation before use even the present invention relates to effectively.

Even the invention still further relates to is not to form the container of band pump that pumping plant also can be realized the gas-barrier property of pumping plant with low cost by the parts with gas-barrier property.

In addition, the invention still further relates to that twin at the container that is arranged side by side 2 band pumps spues in the container, the quantity of the component parts of container is few and the twin that can cut down the cost of component parts and can reduce stack-mounted man-hour of the component parts container that spues.

In addition, the container that the present invention relates to that twin at the container that is arranged side by side 2 band pumps that possess the pumping plant that comprises pump main body and spray nozzle part spues in the container, the twin of 2 medicaments in the container that is housed inside 2 band pumps respectively that can spue according to the opportunity of product design spues.

Preferably, the container of band pump of the present invention, its discharge valve of in-to-in pump machanism that is set at described pump main body can not opened even this valve masuring room is pressurized for by pushing the valve that nozzle is mechanically opened yet.

In addition, the twin of the present invention container that spues is arranged side by side the container of 2 band pumps, and the container of this band pump possesses by having that flexual sheeting forms and cylindrical container main body that end is closed and be installed in the oral area of this container body and have the pumping plant of pump main body and spray nozzle part.The pump main body has the outer peripheral face part of being close to the inner peripheral surface of the oral area of container body, outside circumferential surface sections be close to inner peripheral surface and the state that covered by container body under, be fixed in the oral area of container body.The twin container that spues possesses pump that container with 2 band pumps is held in the base of the state that is arranged side by side and carries out pumping plant and inhales the pump of action and inhale device.

In twin of the present invention spues container, preferably, the discharge opening of the spray nozzle part in the container of 2 band pumps that are arranged side by side adjoins each other, and the pumping plant that possesses the both sides of the container that is used for making with single job 2 band pumps that are arranged side by side carries out pump and inhales the pump of action and inhale device.Preferably, the twin container that spues is constituted as the container body in the container that content is contained in 2 band pumps respectively and uses pump to inhale device and carry out pump and inhale in the action, and the content of the container of a band pump spues from spray nozzle part than the content elder generation of the container of another band pump.

Below, for the container of band pump of the present invention, based on describing as the 1st embodiment of its preferred embodiment and with reference to accompanying drawing.

As depicted in figs. 1 and 2, the container of the band pump of the 1st embodiment 10 is the container of the band pump of the shape of the compactness that pumping plant 13 is fixed in oral area 11b, and this oral area 11b is set at another end of the container body 11 with gas-barrier property.

Pumping plant 13 possesses pump main body 15 and the spray nozzle part 14 that comprises masuring room 19.

Container body 11 forms by having flexual sheeting, and is the cylindrical body that an end (being also referred to as " the bottom ") 11a of a side opposite with oral area (another end) 11b is closed.

In container body 11, accommodate the content (not expression among the figure) that deterioration takes place owing to oxidation.

As such content, for example can enumerate the 1st medicament as the bi-component medicament formula hair dye of the fraction of high viscosity, accommodate the 1st medicament of bi-component medicament formula hair dye in the container body 11 in the present embodiment.Being housed inside the pumping action of content by pumping plant 13 in the container body 11 is attracted and is spued from spray nozzle part 14.

Pump main body 15 has the outer peripheral face part 16 that the inner peripheral surface 11c with the oral area 11b of container body 11 is close to, this outer peripheral face part 16 be close to described inner peripheral surface 11c and the state that covered by container body 11 under, be fixed in oral area 11b.

In order to prevent the deterioration of this content under the situation of holding the content that deterioration takes place owing to oxidation, container body 11 is formed by the sheeting with oxygen shielding.As such sheeting, for example can enumerate the aluminium lamination pressurizing resin.Container body 11 for example form internal diameter be about 10～50mm, highly (length) be about 70～200mm.

The bottom 11a of container body 11 for example is closed just as described below.At first, pumping plant 13 is fixed in oral area 11b.According to the common method in the flexible pipe container that forms the band pump, the content filling is contained in the container body 11 from bottom 11a.Afterwards, bottom 11a pressed be flat condition, and use known hot weld device, the sealing layer of the innermost layer in the aluminium lamination pressurizing resin thin slice is carried out hot weld each other.At this, Fig. 1 is illustrated in by hot weld to seal described bottom 11a state before.

The pumping plant 13 that is fixed in the oral area 11b of container body 11 is generally formed by the synthetic resin of polyolefin resin etc., and as previously discussed, is made of pump main body 15 and spray nozzle part 14.Pump main body 15, portion possesses the known pump configuration that comprises masuring room 19 within it.Specifically, possess cylinder 20 cylindraceous, be close to the inner face of cylinder 20 and the piston 21 that slides, be set at cylinder 20 the bottom suction valve 22, be set at the discharge valve 23 etc. of the bottom of piston 21.

Pump main body 15, its housing department is made of the outer peripheral face part 16 of cylindrical sleeve tube shape.Outer peripheral face part 16 has the external diameter identical or slightly bigger with the internal diameter of container body 11, therefore, when 15 insertions of pump main body were installed on the oral area 11b of container body 11, the inner peripheral surface 11c of the outer peripheral face of outer peripheral face part 16 and oral area 11b was close to securely.

The outer peripheral face of the outer peripheral face part 16 of pump main body 15 is formed by polyolefin resin with hot weld etc., after pump main body 15 is installed on the oral area 11b of container body 11, by using known hot weld device to implement hot weld from the outside of container body 11, can be with the leak free state inner peripheral surface 11c of the oral area 11b of the outer peripheral face of the outer peripheral face part 16 of tight joint pump main body 15 and container body 11 securely.

Spray nozzle part 14 is set to be connected in piston 21 and outstanding upward from pump main body 15.By pumping plant 13, for example by repeating pressing operation, thereby piston 21 is slided closely with respect to cylinder 20, and, can via suction valve 22 content be attracted to the masuring room 19 from container body 11 by this pumping action to spray nozzle part 14.Then, can be via discharge valve 23 from spue the content the masuring room 19 of being attracted to of necessary amount of the nozzle opening 14a of the front end of spray nozzle part 14.

As previously discussed, pumping plant 13 is formed by the synthetic resin of polyolefin resin etc., still, by the pumping plant 13 that such material forms, himself does not have the oxygen shielding.So, in the pumping plant 13 of present embodiment, be that inert gasses is filled in the masuring room 19 with respect to the content of container body 11.At this 'inertia' is relative characteristic with respect to content.Specifically, be inert gasses as the content that deterioration takes place owing to oxygen such with respect to the hair dye in the present embodiment, for example can enumerate nitrogen and helium.

According to the container of the band pump of the 1st embodiment, can easily seek container 10 single-piece miniaturizations with pump with above structure.Promptly, pump main body 15 has the outer peripheral face part 16 that the inner peripheral surface 11c with the oral area 11b of container body 11 is close to, be close in this outer peripheral face part 16 under the inner peripheral surface 11c and the state that covered by container body 11 of oral area 11b of container body 11, pumping plant 13 is installed in the oral area 11b of container body 11, so in fact the part that the oral area 11b from container body 11 can be given prominence to is the spray nozzle part 14 as pumping plant 13.Therefore, can easily seek container 10 single-piece miniaturizations, and can realize the design model that balance is good with pump.

In addition, according to the 1st embodiment of the present invention, except can easily seeking the miniaturization of integral container, for the content that deterioration takes place easily owing to oxidation, for example holding under the situation of hair dye, can also avoid the deterioration of the content in the processes such as circulation before use effectively.Promptly, according to the 1st embodiment of the present invention, container body 11 uses to have pliability and has the sheeting of oxygen shielding and form, the outer peripheral face part 16 of pump main body 15 is close to the inner peripheral surface of another end of container body 11 by its outer peripheral face part, thereby the container body 11 with oxygen shielding covers.In addition, by Jie pump main body 15 is arranged, the open end of the oral area of container body 11 (another end) 11b and hold holding between the trunk 12 of content and can guarantee suitable distance, so, can avoid the deterioration that in the process of circulation etc., is taken place thus effectively as the hair dye of content.

Have, the container 10 according to the band pump of the 1st embodiment can obtain following effect again.

Because in the masuring room 19 of pumping plant 13, the content (hair dye) that is filled with respect to container body 11 is inert gasses, so, even be not to form pumping plant 13, also can realize the gas-barrier property of pumping plant 13 with low cost by parts with gas-barrier property (oxygen shielding).

And, kind according to content, can be in the following dual mode any one: container body 11 uses the sheeting with gas-barrier property to form, and perhaps the content of filling with respect to container body 11 in the masuring room 19 of pump main body 15 is an inert gasses.

Then, other the embodiment to the container of band pump of the present invention describes.For other embodiment, mainly be explanation and above-described the 1st embodiment place inequality, the symbol that identical local mark is identical also omits explanation.There is not the place of special version to be suitable for the explanation relevant with the 1st embodiment.Even in other embodiment, also can obtain the effect identical with the 1st embodiment.

The container 10 of the band pump of the 2nd embodiment is used for the part of pumping plant 13 by the parts that will have gas-barrier property, thereby further improves the gas-barrier property of pumping plant 13.

If described in detail, so as shown in Figure 3, in the container 10 of the band pump of the 2nd embodiment, shield member 17 cover pumping plants 13 pump main body 15 the upper surface and be mounted.Shield member 17 is formed by the resin with excellent oxygen shielding of for example aluminium lamination pressurizing resin, PEN resin (PEN), ethylene-vinyl alcohol copolymer resin (EVOH) etc.

In the 2nd embodiment, shield member 17 covers the upper surface of pump main bodys 15, that is, cover masuring room 19 internal diameter cross section partial sum outside wall portions the top and be mounted, so, can further improve the gas-barrier property of pumping plant 13.

Promptly, in the 2nd embodiment, preferably, can cover in advance the pumping plant 13 that the oral area 11b of container body 11 is mounted pump main body 15 the upper surface and shield member 17 is installed, this shield member 17 is formed by the resin with excellent oxygen shielding of for example aluminium lamination pressurizing resin, PEN resin (PEN), ethylene-vinyl alcohol copolymer resin (EVOH) etc.Shield member 17 is also installed in upper surface by covering pump main body 15 in advance, thereby the open end of the oral area 11b of covering container main body 11 also is provided with the barrier to oxygen that is made of shield member 17, so, can avoid the deterioration that in the process of circulation etc., is taken place more effectively as the hair dye of content.And, as the method on the open end of the oral area 11b that barrier to oxygen is arranged at container body 11, though also considered to form the integral body of pumping plant 13 or pump main body 15 by resin with excellent oxygen shielding, but because these resin price general chargeds are higher, so can seek the reduction of cost by the method that shield member 17 is installed on the upper surface of pump main body 15 as the 2nd embodiment of the present invention.

Shown in Fig. 4 (a) and Fig. 4 (b), the container 10 of the band pump of the 3rd embodiment, the discharge valve 27 that constitutes the in-to-in pump machanism that is set at pump main body 26 is not by the variation of masuring room 19 pressure inside but the mechanical open and close valve of mechanically operating for it opens and closes.That is, discharge valve 27 is for by pushing the valve that spray nozzle part 14 is mechanically opened, and also can not open even this valve masuring room 19 is pressurized.

If described in detail, so in the container 10 of the band pump of the 3rd embodiment, the piston 28 of pump main body 26 is by outstanding from the bottom and have the piston installation tube 30 of bottom 29 and have the outstanding slide connecting part 32a that slips closely along the inner peripheral surface of cylinder 31 and the sliding cylinder 32 of the hat-shaped of interior all slide connecting part 32b of slipping closely along the outer peripheral face of piston installation tube 30 constitutes.

In the state before the pushing of spray nozzle part 14, utilize the potential energy of being had of spring members 33, the outstanding card of pushing inner core 34 that is connected in the top of piston installation tube 30 by one ends flange 34a and contacts with the lower end fastener 35a of the top panel 35 of pump main body 26 and block and end.Under this state, the ring-type fin 36 that below the outshot of sliding cylinder 32, projects to the below be embedded in the protruding bottom 29 that is set at piston installation tube 30 above modes in the annular recess 37 of peripheral part be close to, thereby cut off circulation (with reference to Fig. 4 (a)) between the content between them.

Revolt the potential energy of being had of spring members 33 and push spray nozzle part 14, if depress with spray nozzle part 14 and to push inner core 34 and piston installation tube 30, the outstanding card of so at first pushing inner core 34 end flange 34a from the lower end fastener 35a state of contact of the top panel 35 of pump main body 26 up to contact above the outshot of sliding cylinder 32 till move (with reference to Fig. 4 (b)) downwards.So, because piston installation tube 30 relatively moves downwards with respect to sliding cylinder 32, so thereby the ring-type fin 36 of sliding cylinder 32 can make the gap of content circulation from annular recess 37 disengagings formation between them of the protruding bottom 29 of piston installation tube 30.As previously discussed, become following structure: by pushing spray nozzle part 14, thereby move in fact piston installation tube 30 with spray nozzle part 14 one, by making valve body (ring-type fin 36) and valve seat (annular recess 37) thus between sealing break away from the unlatching pump.

That is, the annular recess 37 of the protruding bottom 29 of the ring-type fin 36 of spring members 33, sliding cylinder 32 and piston installation tube 30 constitutes that the internal pressure that does not need by masuring room 19 changes but the discharge valve 27 that mechanically opens and closes.

Then, push inner core 34 and piston installation tube 30 if further depress, the protruding bottom 29 of piston installation tube 30 moves downwards with sliding cylinder 32 so, thereby to masuring room 19 pressurize (with reference to Fig. 4 (b)).So, masuring room 19 in-to-in contents by the protruding bottom 29 of piston installation tube 30 outer peripheral face and the gap between the annular recess 37 of the protruding bottom 29 of the ring-type fin 36 of gap between the inner peripheral surface of cylinder 31 and sliding cylinder 32 and piston installation tube 30 be forced out upward.The content that is forced out by on piston installation tube 30, form opening spue valve opening 38 and flow into the hollow inside of piston installation tube 30 after, again by spray nozzle part 14, spue from the nozzle opening 14a of front end.

In addition, if remove pushing to spray nozzle part 14, so at first piston installation tube 30 relatively is moved upward with respect to sliding cylinder 32 with spray nozzle part 14, so the ring-type fin 36 of sliding cylinder 32 is close in the mode of the annular recess 37 of the protruding bottom 29 that is embedded in piston installation tube 30, thereby inaccessible discharge valve 27.Have, piston installation tube 30 and sliding cylinder 32 become one again, and the outstanding card of pushing inner core 34 ends flange 34a and rises until with till the lower end fastener 35a of the top panel 35 of pump main body 26 contacts, thereby returns to the original state shown in Fig. 4 (a).Follow in this, because the inside of masuring room 19 becomes negative pressure, so the content of open suction valve 22 and container body 11 flow into the inside of masuring room 19.

Then, container 10 according to the band pump of the 3rd embodiment, because discharge valve 27 is not for being the mechanical open and close valve that opens and closes by masuring room 19 pressure inside, so from the band pump container 10 be fabricated onto use during, because the variation of the ambient temperature for example, expand even be filled in the unreactable gas of masuring room 19, can be owing to discharge valve 27 is opened in the increase that causes masuring room 19 internal pressures because of expansion yet.Therefore, the container 10 from the band pump be fabricated onto use during, can avoid being sealing into masuring room 19 in-to-in unreactable gass effectively and leak, and the gas-barrier property that can further improve pumping plant 13 and be with the container 14 of pump.

And the container of band pump of the present invention is not limited to above-described embodiment and various changes can be arranged.For example, container body is in that hold not can be owing to oxidation under the situation of the content of deterioration, might not be necessary to use sheeting to form with oxygen shielding, make means that the outer peripheral face of the inner peripheral surface of another end of container body and pump main body partly is close to except by the hot weld, also can adopt the means of carrying out tight joint by hot melt.In addition, the content that is received also can be other various aqueous contents with flowing power except hair dye.
