Description

Fluid distributor

Technical field

The present invention relates to a kind of fluid distributor, it comprises: a container; One distribution member, this distribution member for example are pump or valve; And an installation ring, it is used for distribution member is fixed to container.Such distributing box is widely used in perfume, cosmetics or the topical agent industry, so that come distributing fluids by pushing a pusher with the finger artificially.

Background technology

The present invention relates more particularly to a kind of like this container: it has constituted a perforate, this perforate has formed a madial wall, and this madial wall has constituted a narrow thin perforate section, below this perforate section, madial wall outwards caves at least partly, thereby has formed a recessed bottom opening section.Secondly installation ring at first comprises a main body holding device, is used to admit the main body of distribution member, and, it comprises a fixing skirt section, and it is joined in the described perforate forcibly.The skirt section has a lateral wall, and it has defined a first area, and it is encased in the narrow thin perforate section in place, and has a second area, when the skirt section by full engagement in perforate the time, it is in place that second area enters into recessed perforate section.A kind of distributing box that has installation ring is disclosed in No. 3 937 366, U.S. patent documents US.In the document, the madial wall of container neck be provided with one the ring all grooves, built in the fin on the lateral wall of skirt section by inlay card in this groove.The diameter of part that is close to fin on the skirt section and is arranged in its top is less than the diameter of fin---and be that convenient skirt section is not as yet by full engagement during to container neck.Can say like this: the inboard profile of the outline in skirt section and container neck is accurate complementary relationship.Similarly, accurately complementation of the shape of fin on the shape of annular groove and the skirt section on the neck madial wall.Like this, between skirt section and neck madial wall, any radially clamping is not set and contacts, just with in the annular groove of fin inlay card in neck, thereby, between skirt section and neck, be difficult to realize no leak.

For disclosed fastening system in 2 792 No. 295 files of FR, just there is such situation.This system has adopted an installation ring, has a pump or valve on it.This installation ring also engages with the madial wall of a container neck, and neck has a narrow thin perforate section, and it is positioned at the top of a recessed perforate section.Installation ring also comprises a skirt section, and it is designed to join in the neck.This skirt section has a projection that is positioned at radial outside, and it is designed to join in the recessed perforate section, and this perforate section shape herein is a ring week groove on the neck madial wall.This inlay card fixed system is to join in the inboard groove of neck by the outer process with annular skirt to form.

The top of lateral process outside, the skirt section comprises the section that a diameter is less.This section engages with the narrow thin perforate section built in the inboard depression of neck top closely.But, from the accompanying drawing of this reference paper, can not find out the diameter of the external diameter of the skirt section section that is positioned at narrow thin perforate section place less than neck.In the text description of this reference paper, also not more description to this.

In addition, in the text description and claims of this document, define secure component very clearly and comprise the inlay card securing device, it can be received in the described depression of neck madial wall; That is to say that this inlay card securing device is to be made of the outside projection among the described embodiment of its Fig. 3.

Summary of the invention

An object of the present invention is by providing a kind of installation ring to solve the defective that exists in the prior art, it can realize fastening installation, also can reach the leak-proof of excellence.

For achieving the above object, the invention provides such scheme: before the skirt section was engaged in the perforate, the external diameter of first area, skirt section was greater than the internal diameter of narrow thin perforate section.Situation then is not like this in file US 3 937366, and in this document, the diameter of first area, skirt section strictly equates with the diameter of tapping neck.Narrow thin perforate section is preferably non deformable substantially, and the first area then is deformable through narrow thin perforate section the time.By this way, be chosen as diameter by diameter greater than narrow thin perforate section with the skirt section, utilize the creep of material just can make the skirt section distortion, thereby narrow thin perforate section can be bitten in the lateral wall in skirt section, guaranteed the leak-proof of fixing closely and excellence therefrom.First area to the inside distortion diametrically can produce a strong radially clamping action, and the narrow thin perforate section of perforate can pressed in the first area.

The additional features according to the present invention, the external diameter of second area are greater than the internal diameter of narrow thin perforate section, but it is less than the maximum inner diameter of recessed perforate section.Second area is forced to pass after leading thread inwardly contracts narrow thin perforate section, then, expands and is loosened by direction radially outside in recessed perforate section.Because second area do not contact with the madial wall of neck at recessed perforate section place, so, owing to existing narrow thin perforate section to bite into the interference effect that causes in the first area,, material reaches second area so being easy to wriggle from the first area.

The additional features according to the present invention, skirt section and main body be an intermediate space at interval.Thereby the distortion of distribution member matrix will not be caused in the skirt section of distortion.

Preferably, installation ring also comprises all flanges of a ring, and its top from the skirt section extends radially outward, its be used to container in perforate connect, can be engaged to the degree of depth in the perforate with the restriction skirt section.

Preferably, flange plays the effect of a thrust transferring elements, is used for joining the skirt section to perforate.

Other the feature according to the present invention, narrow thin perforate section is essentially frustum by one or trumpet-shaped transition phase is connected to downwards on the recessed perforate section.Thereby after the skirt section was engaged in the perforate, the lateral wall in skirt section matched with narrow thin perforate section and transition phase and has improved tightness and leak tightness.

In a modification or in the other design, narrow thin perforate section extends upward for frustum or trumpet-shaped lead-in cable substantially by one.Thereby after the skirt section was engaged in the perforate, the lateral wall in skirt section can match with narrow thin perforate section and lead-in cable and improve tightness and leak tightness.

In one embodiment, the lateral wall in skirt section was cylindric before engaging, and first, second zone has identical external diameter.Preferably, the skirt section has one for the free bottom on inclined-plane, so that be inserted in the perforate in the container.

Description of drawings

Hereinafter with reference to the accompanying drawings the present invention is done more comprehensively to describe, accompanying drawing utilizes the infinite one embodiment of the present invention of having represented for example, in the accompanying drawings:

Fig. 1 is the cutaway view that fluid distributor of the present invention is done, and in the state shown in the figure, installation ring is about to be engaged in the perforated container;

Fig. 2 is and the similar view of Fig. 1 that among the figure, installation ring has been engaged in the perforate of container; And

Fig. 3 is the enlarged view that the detailed structure of installation ring is done, and has represented the skirt section is how to cooperate with perforate.

The specific embodiment

Fig. 1 and Fig. 2 have only expressed the top of fluid distributor of the present invention, thereby, only represent entire container with the neck 10 of container.But dispensers according to the invention is made up of three members, that is to say: container 1, distribution member 2 and installation ring 3.

In this embodiment, container 1 is provided with a neck 10, the projection that makes progress of its main body from container, and wherein, the effect of container 1 is to be used for store fluid.Neck 10 defines a perforate, and it can communicate with the inside of container.But, also can consider to adopt the container of other form of implementation, in these embodiments, container does not have the container of projection, and only is provided with a perforate on container body.Referring to Fig. 1 and Fig. 2, for example can imagine such situation: the end of neck 10 is directly concordant with shoulder 110.Like this, container can have a perforate that does not have neck.Thereby, the also non-essential in the present invention feature of the neck of projection.It is just enough only the perforate with certain characteristic need to be set.In these characteristics, can find out that from Fig. 1 and Fig. 2 neck 10 has a madial wall 11, it is not columnar, but has a narrow thin perforate section 13, has thereunder formed a recessed perforate section 14.Narrow thin perforate section 13 be positioned at neck outlet near, formed the top 12 of an annular therefrom.Narrow thin perforate section 13 preferably is connected with top 12 by a frustum or trumpet-shaped lead-in cable 15.In addition, narrow thin perforate section 13 is connected on the recessed perforate section 14 by a frustum or trumpet-shaped transition phase 16.Narrow thin perforate section 13 is essentially cylindrical shape.Recessed perforate section 14 also can be designed to be essentially cylindrical section.Also recessed perforate section 14 can be designed to encircle the form of all grooves, this groove extends at the certain height place of neck, and extends downwards with the part that narrow thin perforate section 13 equates basically by one section diameter.Also recessed perforate section can be designed to the form of many grooves, these grooves are distributing on the inner peripheral surface of neck.In other words, no matter what form is recessed perforate section 14 are, its local at least internal diameter is greater than the internal diameter of narrow thin perforate section 13.In the embodiment shown in the figures, narrow thin perforate section 13 is columnar, and recessed perforate section 14 extends downwards from narrow thin perforate section 13, and its start-up portion is a trumpet-shaped transition phase 16.Because the diameter of trumpet-like transition section 16 is greater than the internal diameter of narrow thin perforate section 13, so can be seen as the part of recessed perforate section 14.Then, recessed perforate section 14 continues continuity downwards and is connected with shoulder 110.Certainly, also can cancel transition phase 16, thereby recessed perforate section 14 is connected with narrow thin perforate section 13 by the shoulder of a pointed shape.Under these circumstances, just need not to make the neck extension certain height, and can on shoulder 110, form the perforate that has narrow thin segment and recessed section.

In this embodiment, distribution member 2 is a pump or valve, it comprises a pump housing 20, and its top has formed the eckband 21 of an outside projection below eckband, and the pump housing has formed a base portion 201, below base portion 201, connecting one section second base portion 202 that diameter is less, between two sections base portions 201,202, is a transition phase 203, can be clear that more that from Fig. 3 it is the form on frustum rank.Below second base portion 202, main body 20 has formed another littler base portion of diameter.Because main body 20 comprises four sections base portions that diameter successively decreases from eckband 21, is level Four hierarchic structure so we can say main body 20.But this only is a specific embodiment, nature, and main body 20 also can be made into accurate cylinder.The practice is easily, and a throw rod 22 is set on pump 2, and it is slidably received within the main body 20.Throw rod 22 extends below a pusher 23, has formed a dispensing orifice 230 on the pusher.For driving pump 2, as long as push pusher 23, just passable throw rod 22 is pushed in the main body 20, this will cause a certain amount of fluid to be transported to dispensing orifice 230 places through throw rod 22.Such pump or valve are quite common.

The purpose that installation ring 3 is set is to keep distribution member 2, and is fixed in the perforate of neck 10.For this purpose, installation ring 3 is provided with a main body holding device 31, and it is the form of sleeve, and it can accurately engage with the maximum gauge of first base portion 201.The end of sleeve 31 preferably is connected to the below of the eckband 21 of projection.By firmly installation ring 3 being joined on the main body 20, just can make it in place.Also be provided with one on the installation ring 3 skirt section 32 is installed, it is used for being inserted into neck 10.Extend with 31 pairs of normal incidences of sleeve basically in skirt section 32.As can be seen from Figure 3, at second base portion, 202 places, skirt section 31 does not contact with main body 20, but leaves an intermediate space 34, and it can prevent to take place any contacting or interference between skirt section 32 and main body 20.Because main body 20 is steps,, but the skirt section also can be obtained same intermediate space 34 with respect to what sleeve 31 was designed to that rank contract shape so such design is possible.The skirt section has a lateral wall 320, and as can be seen from Figure 1, before skirt section 32 was engaged in the neck 10, its shape was cylindric substantially.Bottom in the skirt section is provided with a chamfered part 323, and it can be convenient to the skirt section is inserted in the perforate of neck 10.But above chamfered part 323, the lateral wall 320 in skirt section is essentially cylindrical shape.

In the present invention, the external diameter of skirt section 32 cylindric lateral walls 320 is greater than the internal diameter of narrow thin perforate section 13.Thereby, shown in Fig. 2,3,, just must exert oneself to engage forcibly for skirt section 32 being encased in the perforate of neck.Join the degree of depth in the neck perforate in order to limit the skirt section, the flange 33 in a ring week is set on installation ring 3,32 top extends radially outward from the skirt section for it.Can find out from Fig. 2 and Fig. 3, when flange 33 abuts to the top 12 of neck 10, arrive final maximum engagement state.Like this, skirt section 32 is both narrow thin perforate sections 13 of extend through just, have also extended in the recessed perforate section 14.Say that more definitely skirt section 32 also extends through lead-in cable 15 and transition phase 16.Say roughly, can form two zones on the lateral wall 320 in skirt section 32: promptly one is encased in first area 321 in the narrow thin perforate section 13 and a second area 322 that is encased in the recessed perforate section 14.As can be seen from Figure 1, before engaging, because the lateral wall 320 in skirt section 32 is cylindraceous, so these two zones can't distinguish.As can be seen from Figure 3, first area 321 is subjected to be out of shape on the radially inner direction of acting on of narrow thin perforate section 13, and second area 322 is not owing to contacting with the madial wall 11 of recessed perforate section 14 necks, so do not deform.Thereby the first area 321 in skirt section 32 utilizes the creep of material and produces distortion.In order to make material that creep can take place by this way, when skirt section 32 is engaged in the perforate of neck, must make narrow thin perforate section 13 shape that remains unchanged.In real work, can obtain such effect by material manufacture neck and installation ring with different hardness.For example, container 1 useable glass is made, and installation ring 3 then can be made of plastic.But also can make container 1 and installation ring 3, for example, utilize the design on structure design or the wall thickness to make skirt section 32 realize deformable characteristic more subsequently with same material.Also can make the first area have better deformability by the length that limits narrow thin perforate section.This height can reduced one-tenth rib ridge or the form of rib rib, thereby can more easily bite in the first area.

Should be noted that: the lateral wall 320 in skirt section 32 also contacts with lead-in cable 15 and transition phase 16.This helps the skirt section is fixed in the perforate, this effect derives from the fastening effect of barb, under this condition, narrow thin perforate section is used as the profile of embedding, it is fastening that mounting means of the present invention does not belong to inlay card, reason is: when initial---before engaging, do not have any depression that is used to admit narrow thin perforate section 13 on the skirt section.What should also be pointed out that is: by adopting such skirt section, can improve leak tightness significantly, reason is: the radially clamping action at 321 places is very strong in the first area, under any circumstance, all than that describe among the prior art file US 3 937 366, only much firm with the fastening situation of installing of inlay card.

The lateral wall 320 in skirt section 32 is represented as accurate cylindrical shape in the drawings.But, also can make the shape of the lateral wall 320 in skirt section 32 for other, for example can be for step-like, and make the external diameter of second area 322 be greater than or less than the external diameter of first area 321.Design philosophy of the present invention is such fact: before in the perforate that is engaged to neck, the diameter in skirt section 32 is greater than the diameter of narrow thin perforate section 13, thereby forces the skirt section around narrow thin perforate section 13 creeps to take place.
