Description

[Detailed description of the invention] Title of the invention: Spray head for spray container for delivering foamy substances Technical field The present invention uses foam (hereinafter referred to as foam material) as a spray container spray container. Regarding play heads. This spray container should be placed in the exit passageway of the spray head. Equipped with manual delivery valve. The spray head has an outlet downstream of the delivery valve. Aisle fully automatically 31! ! A closure element is provided for the location. This closed H element has a blocking effect. is performed with a delay relative to the delivery valve.

l) If the spray head of this cover (U.S. Pat. No. 4,437,592 Specification V) In this case, the closing valve opens before the delivery valve and closes afterwards. However, foamy substances Rosol container or spray container (the sharpener delivered from the spray can is inside the spray container) When the aerosol product initially contained in liquid form opens the delivery valve t-, the restraining action H1 occurs. t'' to ensure that it does not come out of the spray head without receiving it and that it is completely lathered at the beginning. It is advantageous to do so. However, if the closing element (such as the delivery valve) opens first, then in this case the At least a portion of the rosol melts several times before the powder becomes completely foamy. Zaranimata, The foaming agent that comes out with some damping 5Ch rice can wait for stronger foam formation. Since we know this, 4P will be released after a slight delay. Also, the closing element is closed. Therefore, the product that remains between the delivery valve and the outflow orifice will be trapped in the closed outflow passage. Secondary bubbling occurs and the closure element is opened again under the pressure of the foamy material to release the flea-like material. It continues to leak.

The present invention solves the spray head problem mentioned at the beginning; The outflowing foam material has a relatively strong impact, and the flow of the foam material after the closure of the closing element. It is better to avoid it.

The present invention solves this problem by delaying the opening of the closing element with respect to the enclosure of the delivery valve. It will be decided by this. The closure element allows gas to escape when it is in its closed position. However, the liquid will not leak out.

In this folding method, the closing g-element, which opens later, initially acts like a brake on the foam. It increases the overall strength of the foam. Seal the bowl II; If the gas continues to leak out Therefore, it is possible to avoid double foaming and foam outflow at the same time.

The closing element is moved into the closed position by the force of gravity when the spray container is upright. It is best to insure it. In this # section, the closure element is pumped out due to the pressure of the foam material. It is only when the valve is opened that it opens easily due to the pressure of the foam, and vice versa. disappears, the closing element closes again until the delivery valve closes again. Also in closed position Excess gas will escape, but the flow will be seasoned.

T, that is, remains between the delivery valve and the outflow orifice of the outlet passage? II-like residual surface items , it cannot continue to flow and its state cannot be changed because there is no air supply. Can not.

As mentioned above, the closed @ main nest is substantially mushroom-shaped and the stem of the 7 is in the S-line direction within the exit passage. When not introduced in the opposite direction, the radial protrusion of this handle part has a recessed part that is located in the exit passage. With a start, the rim of the mushroom-shaped head is located at the rcrfJ position and the exit passage is opened. The radial protrusion digs into the periphery of the outflow orifice in the closed position VC; 91 The two shafts of rock are separated by the same distance. The closure element consists essentially of rigid O material. Small At least one thread of axial passageways passes through the radial protrusion or recess. This way In this way, the closed@element has a ffflJ limited movement in the exit passage with the jump in the closed and open positions. I can move. This distance determines the opening movement of the closure element.

At this point, if the radial protrusion hits the bite when in the closed position, at least Preferably, the saw-shaped head is constructed of resiliently flexible material. L of mushroom-shaped head The rim of the foam discharges the foam from the rim of the outflow orifice of the outflow passage under pressure. The valve moves in the opposite direction with a slight delay when the valve opens, and foamy substances flow out. It becomes more. When the delivery valve is closed, the periphery of the mushroom-shaped head is foamed due to its inherent elasticity. As the pressure disappears, it returns to the closed position again with a slight delay.

Alternatively, the closed M4 element has at least one through hole f: You can also configure it manually. This through hole is located at the periphery of the outflow orifice of the exit passage. by applying a diaphragm or by at least one radial web. It can be mounted on a bottle kept coaxially within the outflow passage. Also, this closing element It has the same function as the saw-shaped head-like closed @ element, and is exactly the same as this mushroom-shaped element. It's so easy to install and use.

The outlet passage can be subdivided into a first part and a second part. The second part, The closure element is a gold skewer attached to the first part.

The first part constitutes a suitable exit passage through which it is easy to insert the second part. However, this is the desired format.

Therefore, when the closing element is placed in the closed position, there is a radial protrusion at the rear of the biting part of the outlet passage. t-Wait until the spray head is closed until the closing element is in the outflow channel. so as to form a substantially flat cover connected to the outer peripheral edge by a film catcher. It is possible to create an iC barrel.

This film joint is created by the force generated by the closing fa element acting towards the closed position due to gravity. It has a spring force that acts toward the weak open position. ffJ chain element in closed position The protrusion is at a distance from the cutting capital in the opening direction. The closing element is of the exit passage. It is located on the periphery of Orisuis.

In this construction, the film joints can be made with a single former and still be connected to the drive assembly. The closure and closing elements can be used to separate the two parts either by separate formers or by a single former. In this way, unlike when each stone was made separately, the stones were mutually lost. A permanent correlation to the conforming manufacturing tolerances of the drive assembly and closure elements is ensured. Care should be taken to ensure that the drive assembly or closure device and the Multi-XW, no need to classify closure elements that are formed in large quantities according to compatible wall tolerances. become.

The preferred embodiment shown in the drawings with the non-inventive tVA will be described in detail below.

The spray head according to FIGS. 1 and 2 has a substantially mushroom head-shaped cross section. A closure device with a spray container delivery valve for delivering the rich foam material (not shown) A drive assembly 1 and a protective housing 4 are provided. Closing part fi12f fiK is a closure element 3 in the form of a mushroom head [inserted with a snap action.

The drive assembly 1 includes a vertical mouth tube 5. This outlet pipe 5 is an outlet The first part of the passage 6 is formed so that the socket 7 of the closing part yg3 is inserted into this outlet pipe 5. entered. The socket γ completely forms the second part of the outlet passage 6. Exit f5 and socket tγrl: Closely coupled to each other causing friction? It will be closed accordingly. Axial direction of exit 'W5 The lower part has an inlet 8T-formed to receive the outflow end of the delivery pipe of the delivery valve. Ru. The outlet passage 6 is surrounded by a wall 9 extending transversely to the outlet passage. Partly based. In Sorazekabe 9, Mizue A is released into a spray container. The logel fluid may initially become foamy.

10μ soil wall of drive assembly 1, snap-fitting action on top edge of spray container Connected to the upper edge of the MXwJ assembly 10 installed on the outer side 11 in the same radial direction 7 on the side of one side of the outflow pipe 5 (9 m on the left in Figure 1)? Located at the top. on wall 1u Made of flexible material. Therefore, the drive on the opposite side of the observance point between each wall 1υ, 11 By fully closing the stage 12, no pressure is exerted on the delivery pipe of the delivery valve connected to the inlet 8. I can do it. A delivery pipe [also known as a pusher, a delivery pipe] that also forms the closing part of the delivery valve. Open the drain valve.

rf3 chain element 3 is substantially mushroom-shaped. The seventh handle part 13 is centered on the exit passage 6. Insert in the linear direction. The handle portion 13 has ff1fI5 attached to the lower side of the biting portion 15. A radial protrusion 14 in the form of a bead is present. The biting portion 15 is located in the radial direction within the outflow passage ε. It is formed by a bead that protrudes inward in the same way as p. Closing element 3 shown in FIG. In the closed position, the closure element 3 rests on the periphery 18 of the outlet orifice of the outlet passage 6. Wait for the entire J'IR edge 16 of the mushroom-shaped head 1γ to be removed. The radial protrusion 14 is in the closed position. It has an axial distance d from the biting portion 15. Distance drl:, closure made of rigid material The movement of element 3 is limited to a certain extent. The axial passage 19 is formed by the radial protrusion 14 It crosses at the upper side l of the protrusion forming the gold bite part 15. Mushroom-shaped head 1 of closure element 3 7 is located approximately within the axial recess 20 of the widened part of the saw-shaped head of the chain device 2. I'll pay it to you.

When the drive stage 12 is fully pushed and the delivery valve t is closed, the contents of the container are released under the pressure of the propellant. 9VCFfJ flows through the ratio sending valve and the 7th delivery pipe t''. From the wall 9 this content bubbles out and heads towards Of5 and the socket 7. this place The combined contents correspond to VJ chain element 31C shown in FIG. 1 and occupying the fc closed position. closure element 3 is fc plus slow fLτ under the thrust of the foam material against gravity (or its weight) Accordingly, in this open position, the foam material can flow out to the open position 1C shown in Figure 2. It acts like a brake. This damped release of foam reduces the Strong stones increase in weight.

When the pressing force is removed from the actuation button 12, the delivery valve closes at T and closes f. a) J3 continues to maintain its open position under the pressure of the foam material.

When the spray container is upright and the outlet passage 6 is in the corresponding vertical position, it is necessary to close it. The element 3 returns to the closed position as the pressure of the foam decreases. Or the closure element 3 is Also, the emitted foamy substance is wiped away! "Then it is pushed back to the closed position. In the closed position, the gas continues to emit through the non-sealing closure between closure element 3 and closure device 2. The foam or liquid that forms in the outlet passage 6 is retained.

The residual product remaining in the exit passage circle should not change its condition when exposed to air. Ruru.

Figures 3 and 4a Summer closure for use with drive assembly 1 Location 2ak is shown. In the closure device 2a, a similar mushroom-head closure element 3a is rigid. It is made of elastic FFJ&'ζ material without any need to wait.

The passage 19a has no finger portion 13a″r″ and is formed in the conical shape of the socket 1a. It is a provision. Therefore, the radial protrusion 14a of the handle portion 13a is delayed in the peripheral direction. However, the cut-in portion 15a is interrupted in the peripheral direction by the passage 19a. Protrusion 14a Since there is no distance in the axial direction from the biting part 15a, A is constantly trapped in this biting part. Ru.

When the delivery valve is opened, the t1 closing element 3a is not lifted up, and the 7th edge 16 is bubbled. It is a fe wall that is surrounded upward in the axial direction by the pressure of the material. In this way The closing element X3a is moved to the open position (not shown) with a slight delay t#. After the cell is closed, the force returned to the edge 16 causes the edge 16 to hit the edge 18. The barrel I bends back again and the flap edge 16 moves to the closed position. Therefore closing element 3a The cl opening/closing is similarly delayed with respect to the opening/closing Vζ of the delivery valve.

Figure 5? In the case of a spray head based on ζ, the top part a of the m-motion assembly 1a is a The book is made up as a square-shaped protrusion 21. The snow 5 that comes out is placed at the bottom 22 of the protrusion 21. It is molded into the body. The exit passage 6 is in the axial direction of the bottom fli22 t) The top is closed by the dense MMJ edge 23 protruding from the top. μ at the top of the protrusion 21 Closing element 3bk mounting tab in the form of a hood made of elastic rubber-like material. Closed @ Yoka 3a projects radially inward into a peripheral groove aI on the outer side in the medial direction of the protrusion 21; The annular bead t serves as a snap-acting attachment point. The bottom of this hood is Under tension, the entire periphery of the outlet orifice of the outlet passageway 6 forms a sealed lHJ edge. Form a diaphragm mounted on 23. The bottom of the hood forming the closure element X3b In other words, the diamond slam has a through hole 24 completely formed on the outer side of the sealing peripheral portion 23 in the rearward direction. I'm doing it. Each through hole 24 has a sealing edge 2 in the closed position of the closure element 3b as shown. The diamond 75 membrane that is sensitive to 3 prevents the release of bubbles or powder, but the diamond 7 Is the closing force of this room so high? Passage of four gases is not obstructed.

Even in this example, when the drive stage is 12t'' pressed, the delivery valve is first opened (not shown). When the clumps are generated, sufficient pressure in the outlet passage 6 of the outlet tube 5 causes the diamond to be generated. Raise the flam from the sealing periphery 23 and the foam lX will be released through the hole 24t''. I will do it. On the contrary, when closing the delivery valve by removing the pressing force of the shift stage 12, The earphragm only returns to the closed position shown after the pressure in the outlet passageway 6 is removed. .

In this case as well, the perforated diamond slam does not function as a brake on the foam material. However, sora Bedboard (I don't have one installed.

In the case of drive Jt177 SENG LI) b according to FIG. 6, the outlet pipe 5a is In the vertical direction, the direction is perpendicular to the horizontal direction, and the foam material is almost horizontal. Or, the xiC is made so that it can be attached to the lower blade.

An annular groove 25 is formed concentrically with the outlet passage 6 at the end of the outlet pipe 5a. in this case Also, the closure element 30 is in the form of a hood. However, the free end of the outlet pipe 5a is Friction fit. Also, at the bottom of the closure element 3C there is a diamond made of an elastic rubber-like material. Form a flam. This tire plum is flush with the annular groove 25 and shown in the closed position. The diamond slam that hits the edge 23aK of the exit orifice of the exit passage 6 The through hole is made of 24-karat gold.

The drive stage 12a is used as a pusher and in this case also as a delivery valve for the spray container (not shown). opens first.When opened in this way, the propellant that pushes up the fluid becomes 6 folds or emulsified. The product to be released is at the inlet 8 at the exit pipe 5ac) extending transversely to the direction of flow. It flows towards wall 9. The wall 9 also in this case contaminates the function of the deflecting wall and the exit passage 6 The liquid inside produces bubbles. p closed due to the pressure rising in the outlet passage 6 at next A @ element 3 The diaphragm c is lifted from the peripheral edge 23a of the outlet orifice of the outlet passage 6. to release a foamy substance. In this case also the diaphragm of the closing element 3c Ramba, l11! Forms a brake that helps in the coagulation of Asahi substances. closure The return of the diaphragm of element 3c to the closed position likewise causes the dissipation of the pressure in outlet passage 6. Correspondingly, there will be a delay charge for closing the delivery valve. Similarly, the closed fa element 3C In the closed position only gas, but not the footwear, can escape from the outlet passage 6.

In the case of the spray head shown in FIG. roughly corresponds to the drive assembly according to FIGS. 1 and 2, except that I am responding. The socket 1b, which similarly widens radially towards the upper free end, is # At least one radial web 2γ forming a source direction @7C2B There is a coaxial pin/26 held coaxially within the channel 6. The closure element 3d is substantially 7-domain or It has the shape of a pot. The JIIJ wall of this hood or pot is made of a resilient rubber-like material. It snaps into a coaxial annular groove in the end face of the socket γb that bottoms out. Fuu The bottom of the closed element 3d is a diaphragm with a hole 24' in the center. Fully formed. 824 is in the closed position shown in FIG. It is p-based by Yafram. In this case too, the closing element 3d or the seventh diaphragm is The pressure in the outlet passage 6 causes a delay compared to the opening and closing of the delivery valve (not shown). accordingly, it is moved to the open or closed position. In this open or closed position, the elastic diamond The flam is lifted off the pin 26 and returned to its position by spring force. It's number 6. Again, in the closed position, gas is allowed to escape, but fluid is not.

The gas passes through the gap between the pin 26 and the diaphragm and through the outlet lower orifice 24. However, the closure assembly 2b is tightly attached to the outlet pipe 5.

In the case of the spray head shown in FIG. 8, the drive assembly IJ1cL is The drive assembly shown primarily in FIGS. Corresponds to Buri 1. The closing assembly 1J2c, which is tightly inserted into the outlet pipe 5, An annular groove 25a is provided surrounding the socket 7c. Groove 25a is a hood or port. An outlet orifice 24 is formed in the diaphragm of the net-shaped closure element 3θ. closed The chain element 3e is made of an elastic material and has a radial shape that fits into the annular groove 25a with friction. Friction is applied to the annular groove 29 on the end surface of the outer wall 30 surrounding the inner side wall and the socket 7c. and a radially outer circumferential wall that fits therewith. The diaphragm of the closing element 3e is In the position, the outlet orifice of the outlet passage 6 is in contact with the circumferential edge 23a, and the circumferential edge 23a is The conduction to the radially outer through hole 24 is closed. How this spray head works corresponds roughly to the type of spray head shown in FIGS. 5 and 6.

In the case of spray heads according to figures 10, 11, 12 and 13 Drive assembly 1e is generally similar to the drive assembly shown in FIGS. 1 and 2. It corresponds to this. The substantial difference is that the drive assembly 1e is constructed in one piece. This means that the drive assembly 1e has a separately configured closure assembly. Not worth it. The closing element 3f then closes the exit opening of the exit passage 6 through the film joint 31. a substantially flat cover in the form of a flat hood connected integrally to the outer periphery of the orifice form. That is, the element 3f does not form a handle portion like the mushroom-shaped closure element 3. do not have. a recess formed by the radially outwardly extending outlet orifice of the outlet passageway 6; The bottom of 20 is provided with four axially projecting webs 32. Each web 3 2 forms a biting part 15b (Fig. 13) similar to the biting part 15a (Fig. 3). It has a protrusion that protrudes outward in the radial direction.

After attaching the drive assembly IJ 1e to the spray container, the closing element 3ft-No. 11 After folding into the closed position shown in FIGS. As is clear from FIG. Partially surrounds the inner periphery of element 3f. The film joint 31 is the circumference that partitions the recess 20. It appears in a recess 33 in the wall. The upper part of the drive assembly 1e is a drive button 12b. It can be tilted to the side by applying pressure to it. In this case, C-shaped miso hole Wall 10 separated from wall 11 by slot 34 (shown in plan view in FIG. 10) Pivoting downwards on the web connecting the walls io, 1i to each other between each end of 3. Open the delivery valve. The film joint 31 can be used even if the spray container is held at a slight angle. Or, even if the tube that separates the outlet passage 16 is tilted somewhat against the horizontal wall 10, it is difficult to open the valve. The closing element 3C is elastically moved by its own weight into the closed position where it rests against the peripheral edge 18. It has negligible elasticity or return spring force to hold it in place. Therefore, each of the above embodiments As in the case of , the closing element 3f controls the pressure of the bubbles generated in the outlet passage 6 during the delay time. Only after a slight delay does the closing element 3f move into the open position.゛This opening position In this case, the protrusion 14 hits the recessed part 15b, and the foam material is trapped in half of the inner peripheral edge of the outlet passage. A narrow half between the radial teeth 35 (or webs) and between the peripheral edge 18 and the closure element 3f. An annular gap between the radial clearance housing, the peripheral wall of the recess 20, and the periphery of the closing element 3f, etc. You can leave. The width of the radial gap corresponds to the distance d.

In this embodiment, the film joint 31 is connected to the drive acenob 'J1e and the closure element 3. Even after making f or these with a single molding tool, it is not possible to use either a separate molding tool or a single molding tool. Even if you use this, the two parts will remain connected to each other, unlike creating them separately. There are some advantages. Therefore, the manufacturing tolerances of the drive assembly 1Ji6 and the closing element 3f are met. Manufactures that are typically different from each other take care to ensure that a continuing correlation is obtained Drive assembly 1 generally formed in large quantities with multiple or multiple forming tools with tolerances e and the type of closure element 3f will need to be determined according to the corresponding manufacturing tolerances.

Instead of circular (top view) closure elements as shown, polygonal, e.g. quadrilateral closure elements can also be used. chain elements and corresponding drive assemblies normally having the same structure as shown; You may also provide a
