Description of the Invention: [Technical Field to Which the Invention Is Applicable] The invention relates to an improved manual operation which can dispense a large amount of fluid substance in the form of a liquid, an emulsifiable substance or the like via a hollow operation lever. The pump enables the substance to be dispensed while preventing the passage of fluid (air, gas, or liquid) between the outer surface of the rod and the adjacent surface in the bore of the pump ring cover at any location and under conditions of use. And the rod extends through the pump ring cover and the pump ring cover is translatable. [Prior Art] Many types of manually operated pumps are known to be used for dispensing a large amount of fluid extracted from a container in which the pump is mounted, via a cavity of a cup, during operation: fluid (liquid or creamy) The hollow rod extends to the outside of the pump body by passing through a hole provided in a ring cover forming a portion of the pump and defining one end of the pump. The term "ring cover" means any body or member for closing the pump body at one end and for enabling the rod to pass. Known pumps are mounted on a vessel where the pressure in the vessel is substantially equal to atmospheric pressure.

In order to prevent the vacuum from forming in the container when the pump is pumped from the container and the fluid is dispensed, a channel or gap must be placed in the pump to allow the atmosphere to pass through the 312XP/invention manual (supplement)/96_06/96107978 5 I3?6270 2 In the container, the pressure therein is maintained at a substantially constant value of f.

The problem is that it penetrates into the container. The second:: This may deteriorate the characteristics of the fluid substance contained in the container; and when the container and the millet are placed in a horizontal position or the chestnut is facing downward from the container, the body may leak through the passage or leak to the container.

The dispensing device used allows the discharge of such substances' and the dispensing device opens or closes the container to prevent or prevent the dispensing of the substance. 312XP/Invention Manual (supplement)/96-06/96107978 6 1^/0270 13⁄4 Λ ^,, Λ 'Also known that the chestnut can be used to dispense the substance and pressurized gas from a container containing a fluid substance and pressurized gas (which is sealed in it). Some structures of these ^ look similar The structure of a pump that is normally used for a non-inner pressurized state, but which is significantly different. Some of the pumps are described in, for example, US 3,211,346A, US 4'511'069A, and GB 1537436A. The teachings of these patents are incorporated herein by reference. The pumps cause problems that make them difficult to use and actually hinder their practical use. In this regard, these milletes are substantially similar to conventional ones. Form, but different from the cup body, and the hollow body of the cup body is sealed, and the ring is sealingly applied to the mouth of the container containing the pressurized substance of the fluid substance f. The body provides a perforated chamber 'fluid material at The chamber is raised into the chamber by the pressure of the container A. The chamber is limited by a piston that is sealingly translatable along the inner surface of the cup body: a hollow rod connected to the piston The hole provided in the pump ring cover is pierced and can be sealingly translated through the hole. In the static state, the cavity in the chestnut is closed by the compression-pulsing piston acting on the cup body. The cup-shaped body is closed by the one-way valve. When the chest is stationary, the pressurized fluid substance existing inside the millet acts on the living body to maintain the chestnut closed. Since there is no hole or void or the passage is provided, the body This will cause the fluid substance or pressurized gas to be in contact with the piston, facing the upper surface of the inner surface of the pump body. The consequence of this situation is that when the pump dispenser is operated to dispense the substance, the pressure must be applied to the pump rod, which is greater than the usual 312 ΧΡ / invention instructions (supplements) / 96-06/96107978 7 The pressure required by the pump, i.e., to overcome the spring thrust acting on the piston and overcome the thrust exerted by the pressurized fluid material present in the pump cavity on the same piston. Therefore, it is more difficult to operate the pump within the container in which the pump is installed. ~ [Explanation] The main object of the present invention is to provide a __ seed chest, any of which is used, :: ' does not allow air, gas or fluid on the outer surface of each rod and the hole in the pump ring cover Pass between the surfaces. Another object is to provide a pump that is sealably mounted to a container that defines a hermetically sealed space, however, the pump ' extracts and dispenses a large amount of fluid material from the two chambers. The goal is to provide a body that can be easily prepared (in the initial: when the 'liquid material can be extracted from the container with the fruit installed): = a manual delivery of a certain amount of sealing contained in the container The pump is used to achieve 'the kind of chestnut contains: a cup-shaped body, two: one is sealed on the open end with a ring cover, and the one-way valve enters the lower part: 'fluid material can pass through the pump chamber The chamber is drawn 'to be delivered to the outside; the lower:;: = the lip 4A that is translated from the lower portion of the lip, and the lip of the inner surface of the sealing surface of the two, and the edge of the inner surface of the sealing rod The free end of the rod 5 protruding from the outer chest to distribute the fluid: as = through the first purchase of the self-sister, the cavity of the rod 5 in 312XP / invention manual (supplement) / team 〇 6/96107978 8 1376270 - gap: 70 Open, the gap 7.

The pump comprises a cup-shaped body which is closed at the end-by-ring cover 2, and at its other end there is a hole 3 defined by a container having a hollow space defined by a container The container is fitted with a chestnut ring 2' at its mouth and sealed in any known manner (for example, by weld jointing, 312XP/invention specification (supplement/96.06/96107978 1〇1376270 or other means) • The inside of the cup-shaped body houses an annular piston 4 having an annular shape that can be translated along the inner surface of the cup-shaped body and sealed against it.: edge 4A, and another An annular lip 4β that can be sealed along the outer surface of the hollow rod 5 (on its free end, mounted with any known type of operation and dispensing push button B), which is sealed against the surface, the hollow The rod 5 I is axially translated via a hole provided in the flange 2, and the cavity of the t-bar 5 is previously sucked to the lower surface of the piston 4 (refer to the figures) The fluid substance in the lower pump chamber 8 between the H human σ holes 3 can be discharged to the outside (and thus used), the pump The inlet opening 3 houses a one-way valve consisting of a ball η (or other sealing element) which can be placed at the end of the upper end of the hole 3 and form the chest body. A portion of the termination element 13 moves between. The upper chamber 9 is defined in the cup-shaped body between the top of the piston 4 and the flange 2, and via a hole or passage that is directly disposed in the cup-shaped body. The outer portion of the body 1 is in communication: in this way, when the pump is sealingly mounted on the mouth of the container, the pressure in the upper fruit chamber 9 is always equal to the pressure in the container in which the pump is mounted sealingly ( That is, the pressure existing outside the cup-shaped body 1. In the state where the pump is used or is at rest, the outer surface of the rod 5 and the hole of the ring cover 2 through which the rod can be extended and translated. There is a hermetic seal between the opposing surfaces, and the hermetic seal is formed by a portion of the ring cover 2 of rubber or a gasket or ring of suitable elastomeric material in the particular embodiment shown in the figures. (It can be shaped by 312 ΧΡ / hair from a deformable plastic material Ming manual (supplement) /%-06/961〇7978 1376270, such as polyethylene, polypropylene, etc.) (of course, the seal between:::: can still be set in different ways, For example, by simply placing the lip again (not shown for simplicity). = One of the important features of the invented chest is that the hollow rod 5 is always accommodated in the guide hole 'and sealably (4) In this case (in the state where the fruit is made, in all the states of rest), in addition, in the cup-shaped body of the dish: a hole or a channel 1 is provided at the upper chamber 9 of the pump body. As a result, because of the upper chamber 9 * will cause liquid, air or gas to leak on the surface of the rod and the ring m through which the rod extends, so that #裒盖2 is sealed to the mouth of the container (not shown) There is no unintended leakage or leakage of the product, air or fluid between the rod 5 and the ring 12 of the ring cover 2. In addition, the pressure to be injected into the pump chamber to 9 is always equal to the pressure at which the pump is sealingly mounted in the upper vessel (due to the presence of the passage 1). Therefore, it is assumed that the pump is sealingly mounted at the mouth of a known cylindrical container (closed at the other end of the basin by a movable base that moves when the contents of the container ten are dispensed), then the air In any state in which the pump is used, it does not penetrate the container so that the product or substance contained therein is not contaminated by air nor hardened or dried. "The same applies to the case where the pump is installed on a sturdy k-shaped squeezed by atmospheric pressure' or for the pump to be mounted on a rigid container. A particularly striking and advantageous use of the 'Monthly Pump' is in a rigid container (with a pump mounted to define a hermetically sealed space inside the container 312XP / Invention Manual (supplement) / 96_〇 6/96丨〇7978 1376270 ])3 is a fluid, semi-viscous or paste-like substance that is mixed with a low hysteresis liquid to produce a slight vapor pressure under normal conditions of use (ie, at about 21 ° C). The low point liquid is a liquid having a saturated vapor pressure of less than 1.00 kg/cm 2 at 151 and less than 2. 8 kg/cm 2 at 37.80 C. The low boiling point liquid is a fluid chemistry having a boiling point between +151 and +85 〇c and producing a pressure of 1 atm (about 760 mm/Hg). Particularly advantageous low-boiling liquids for use as previously mentioned are selected from the group consisting of isopentane, isohexane, n-pentane, n-hexane, di-methyl-fired, monochloropropane, 1-Bu ethane, 2-chlorobutane, trichloro-fluoro-methyl CFC 11, tri- trifluoro-ethane CFC 113, diethyl ether, sulfonium fluorene, dimethyl hydrazine And acetone. When a low boiling liquid of this type is used, the low boiling liquid present in the vessel evaporates from its liquid phase present in the mixture when it is dispensed by the pump' and automatically restores the required pressure within the vessel (slightly higher) Atmospheric pressure is applied to prevent a vacuum from forming in the container, which would prevent the continuity of the mixture from being dispensed from the rigid container. The pump described with reference to the figures is characterized in that, when at rest, the pressure in the lower chamber 8 of the pump is equal to the pressure in the upper chamber 9, so that the pressure system on the upper and lower surfaces of the piston 4 acts. identical. Thus, in order to dispense the fluid substance through the cavity in the rod (on which the button β is mounted), the pressing force must be applied to the rod (inspection view i to Fig. 3), only to overcome two The thrust of the springs 20 and 30 compresses the fluid material collected and contained in the chamber 8, the force required to cause the lip 4B of the piston 4 and the 312XP/invention specification (supplement)/96-06/96107978 13 The corresponding sealing base in the sleeve 50 is separated, and the collar 5 is protruded from the lower portion of the rod 5 in the pump chamber 8. In a manner known in the art, the lip 48 of the piston 4 is urged against the collar 50 (closed to the collar of the collar projecting from the upper portion of the rod 5) to sealingly close the gap 70, the purpose of which is to allow the compressed fluid to advance from the chamber 8 to the rod cavity. The operation therefore does not require: quantity: and 疋 is dedicated to the force required to dispense by a known type of pump mounted on a fluid substance container in a known unsealed manner. At the end of the transfer stroke, the collar is abutted against the terminating element 8 when the rod is pushed down to its travel limit. The terminating element 80 is composed of a section of the cup-shaped body 1 (Fig. 3), and the abutment is placed on the adjacent side of the collar 50 and the μ is placed on the upper surface of the garment U. The inlet and outlet gaps 7 that lead to the rod cavity are still closed in a sealed manner. The chest is returned to its rest position (Fig. 丨) by the position reached by the end of the stroke of the (four) stroke, and it only occurs steadily under the thrust of the bomb I. There is no US3,211, Wei, US4 5n, 嶋 and 537436A of the type of dispenser + extremely difficult situation, in the prior art 'closed sealed upper chamber is placed above the piston of each chamber (ie, such as in the drawing In the beginning of the κ use, the chestnut must be allowed to borrow the mystery. However, the air contained in the chamber 8 must be drained from it. #古, The field/A is discharged so that a vacuum can be formed in the chamber to draw the ampoule right through the hole 3; the fluid present in the pump of the pump is pumped to the chamber. This means that in the self-circle] from the static position of the self-illustration to the pole drop 312XP / invention manual (supplement) / 96-06/96107978 1 / t 1 * 3 / 6270 low stroke end position (Figure 3) At the time, if there is only air in the chamber 8, the air is compressed by the piston 4 and must be discharged from the chamber so that the required Air is established in the chamber to allow fluid to penetrate into the chamber via the aperture 3. For this purpose, a plurality of short longitudinal ribs 9 (shown as four in the figures) from the inner surface 8 of the cup-shaped body 1 Protruding, close to the end of the 7G piece 80' disposed at the bottom of the lip 4A resting on the ribs to be deformed (as shown in ® 3, Figure 3A, and Figure 4, when the sewing room is When traveling f is limited to 'to retain their channels (in order to order, for the sake of simplicity, the symbol is not marked, but clearly visible), and the channels cause the compressed air that may be present in the chamber 8 to rise To the opposite surface 2 of the piston and the cup-shaped body i: 'and discharged into the chamber 9 (and discharged therefrom into the trough via the gap 10)" thus can cause the thinner upper portion of the lip 4A to be inwardly changed 'Here, the recess 1 可见 visible in the cross-sectional view of Fig. 5 can be arranged to allow air to pass freely over the piston. • In this way, the pump can be easily prepared. The pump of the invention can advantageously be used A pressurized fluid having a saturated vapor pressure of less than 2.8 kg/cm2 is produced at 54.4<>>c.
