  The present invention addresses the problem of disposal of viscous composition containers because these containers are typically disposable. Furthermore, due to the high viscosity of the composition, a large amount of material remains attached to the container wall or the like and is discarded together with the container.

  In addition to the container, the refill mechanism allows the container to be reused, and the downsizing of the refillable container can also perform two important actions: 1) Due to its small size, put it in a pocket / handbag / wallet etc. for convenient use on the go, and 2) take a small sample of the first viscous composition (eg cream) and then It is possible to take a small sample of the second viscous composition, i.e. the user can easily change the composition. However, miniaturization also increases the waste of material, which leaves a relatively large amount of material stuck inside the container, which can become useless, dry out, or hardened. May adversely affect the different compositions introduced into the container. It is therefore important that the dispenser includes a mechanism that allows the viscous composition to be completely emptied from the container.

Thus, according to one aspect, a refillable dispenser for a viscous composition intended to solve all these problems is provided. Referring to FIG. 1, the dispenser 100 is:
A bottle 111 defining a wall defining an upper cavity 114 and a lower cavity 116;
A viscous composition refill mechanism 106 configured to allow viscous composition to enter the upper cavity 114 when the refill mechanism 106 is fluidly coupled to a viscous composition source. A viscous composition refill mechanism 106;
A viscous composition discharge mechanism 102 configured to allow the viscous composition 7 to be discharged out of the bottle 111 from the upper cavity 114 when the discharge mechanism 102 is actuated. Object discharge mechanism 102;
A gasket 105 configured to substantially seal the upper cavity 114 from the lower cavity 116, and moves toward the upper cavity 114 when the discharge mechanism 102 is actuated, and the viscous composition 7 Can move toward the lower cavity 116 as it enters the upper cavity 114.
Is provided.

  When the discharge mechanism 102 is operated, some viscous substance 7 such as cream is discharged from the discharge mechanism 102 to the outside of the bottle 111. In some embodiments, the material discharged from the mechanism 102 is replaced by additional material drawn by the dispensing mechanism 102 with the same actuation. As the substance 7 is withdrawn from the upper cavity 114, the gasket 105 can rise, thus maintaining the pressure in the upper cavity 114 and keeping the (smaller) cavity 114 full of cream. Air can incidentally enter the lower cavity 116 through the hole 171, thereby preventing sub pressure from being formed in the lower cavity 116. When the refill mechanism 106 is activated, the substance 7 enters the upper cavity 114 and pushes the gasket 105 downward, i.e., the upper cavity 114 expands and the lower cavity 116 contracts, and air passes through the holes 171. Release.

  Other embodiments have alternative exhaust / pressure maintenance means.

  Some embodiments may have no wall 171 in the wall, so that the only opening of the bottle 111 is for the refilling and dispensing mechanisms.

  The discharge mechanism 102 can comprise a pump: when the pump is activated, for example, in some embodiments, it is depressed to compress the space within the pump containing the viscous material, which causes the pump to remove the viscous material. Extrude. When the pump is released, viscous material is pulled from the upper cavity 114 into the pump. In a preferred embodiment, the pump is configured to prevent air from entering the upper cavity. In other embodiments, air is placed in the upper cavity but is pumped out.

  The dispenser 100 can be a foam dispenser: In embodiments having a foam dispenser, the dispenser can comprise two or more pumps, which, when used, are air and viscous compositions. Both are moved through a small opening to create a foam, such as a shaving cream. In a preferred embodiment, air is preferably introduced into the pump from outside the bottle 111.

  In some embodiments, the dispenser is automatic and is activated by a signal such as an activation time.

  As shown in FIG. 2, the dispenser 100 includes a cap 103 that covers the discharge mechanism 102, and an outer bottle body 112 that complements the cap 103. The outer body 112 has a transparent window 121 through which the level of the substance 7 can be measured to determine when to refill the dispenser 100. However, some embodiments do not have these features as shown in FIG. The dispenser 200 similarly includes a bottle 211, a discharge mechanism 202, a filling mechanism 206, and a gasket 205. The dispenser shown is empty.

  FIG. 3 shows another empty embodiment 200 that includes a bottle 211, a dispensing mechanism 102, a gasket 205 and a filling mechanism 206.

  FIG. 4 shows a bottle 211 that is partially full, and FIG. 5 shows the same bottle 211 that is completely full with a viscous composition 7.

  The refill mechanism of FIG. 1 is defined as including a tube 104. Thus, the refill mechanism extends from the outside of the bottle 111 over the lower cavity 116 and the gasket 105, thereby allowing the composition 7 to be conveniently provided from the bottom of the bottle 111. The gasket 105 is sleeved to seal on the tube and in the bottle. In some embodiments, the tube can be close to the wall, flush with the wall, or even part of the wall, in which case the gasket is not perforated. However, the gasket can nevertheless effectively seal the upper cavity from the lower cavity.

  FIG. 6 illustrates an embodiment 300 in which the refill mechanism 306 does not extend across the lower cavity 316. Instead, the refill mechanism 306 is mounted within the dispenser 300 so as to extend up to or directly into the upper cavity 314. The dispenser 300 may be particularly useful for filling the dispenser 300 from a container having a dispensing head with a downward facing orifice.

  7 and 8 show the filling of the refillable dispenser 200 with the non-refillable dispensers 400, 400 '. 7 is actuated by a pumping action, while the dispensing mechanism 409 ′ of the dispenser 400 ′ shown in FIG. 8 includes the refillable dispenser 200 and the refilling device. Actuated by pushing non-formula dispensers 400 'against each other. The bottle 411 containing the viscous composition can be pressurized.

  In some embodiments, the refill mechanism includes a check valve.

  In some embodiments, the discharge mechanism includes a check valve (which helps prevent air from entering the upper cavity 114 through the valve).

  In some embodiments, both the refill mechanism and the discharge mechanism each include a check valve.

  Commercially available dispensers can probably be refilled by removing their dispensing mechanism, but for any practical purpose, such refilling is time consuming and difficult, so they are essential. Is not refillable. Furthermore, the size of a dispenser, typically 250 mL or larger, is substantially larger than a refillable dispenser, which is typically less than 100 mL, so it is rarely motivated to refill such a larger dispenser. Not.

  Thus, according to another aspect, there is provided a refillable dispenser of any of the types described above and a kit comprising at least one adapter, the adapter refilling a non-refillable dispenser for viscous compositions. Each of which is configured to allow a fluid connection to be sealed to a filling mechanism of a dispenser of the type. Each adapter is suitable for a particular structure of the dispenser dispensing mechanism that is not refillable. Thus, a set of adapters can serve to couple the first refillable dispenser to various commercially available non-refillable dispensers.

  Many commercially available dispensers have a dispensing head (not shown) that can be removed to expose the dispensing mechanism 409 of the non-refillable dispenser 400, which is then refilled. It can be easily connectable to the mechanism. Such removal typically exposes the structure of the discharge mechanism 409 such as the stem 415 (see FIG. 7).

  The adapter may be a tube having both ends that are the same or different sizes. Normally, one end fits tightly within the refill mechanism of a refillable dispenser and the other end fits securely over the stem of the dispenser's non-refillable dispense mechanism, causing viscosity from a non-refillable dispenser A sealed connection is formed to transfer the composition to a refillable dispenser. Alternatively, the adapter may be the dispensing mechanism itself that replaces the dispensing mechanism from the base of the non-refillable dispenser.

  In other embodiments, the non-refillable dispenser is simply a receptacle that has no dispensing mechanism, such as a cream jar with a top thread and a lid with a matching thread, and the adapter is this In this case, the lid is removed and the jar is connected. In a preferred embodiment, the refillable bottle refill mechanism further comprises at least one sealing ring, a ring 161 of the refill hole 160 under the check valve as shown in FIG. 1 provides a sealing connection (including ball 162 and compression spring 163).

  According to another aspect, a kit is provided that includes a refillable dispenser and a non-refillable dispenser. Unique to the non-refillable dispenser of this embodiment is that the refillable dispenser and the non-refillable dispenser preferably do not require an adapter and seal the non-refillable dispenser to the refill mechanism. It is configured to allow connection to be made. Such a non-refillable dispenser may be a commercially available dispenser, the refillable dispenser being special in the dimensions of the refill mechanism relative to the dispenser mechanism of the non-refillable dispenser. A dispenser that fits, and perhaps more typically a non-refillable dispenser, is specifically designed to fit easily and securely into a refillable dispenser.

  Usually, non-refillable dispensers are of a size that are too big to carry in wallets, pockets, etc. Non-refillable dispensers further minimize material waste.

  It should be noted that non-refillable dispensers are ideal for home use, while refillable dispensers are ideal for use on aircraft, This is because only very small containers of viscous composition are allowed to be brought into the cabin.

  Some embodiments can be operated to have a sub-pressure in the upper cavity when at least the upper cavity is substantially free of material and ready to receive additional material. This can be achieved by having a gasket that cannot move up to the top of the upper cavity, so that when exhausted it can leave a space and can create a sub-pressure in this space. .

  See, for example, FIGS.

  The dispenser 500 includes a rigid body 501 with an upper cavity 502 sealed from the lower cavity 516 by a gasket 530. In particular, the body 501 has sufficient rigidity so that the volume of the upper cavity 502 is substantially constant. The upper cavity 502 can have a volume of, for example, 1 ml to 20 ml (which makes the dispenser a convenient pocket size). The body 501 is a single piece made from a rigid plastic material, a metal such as aluminum or glass, for example manufactured by injection blow molding or extrusion blow molding, or assembled after injection, for example by ultrasonic welding. It can be a plurality of parts.

  The dispenser 500 also includes a discharge device 503 attached so as to be sealed in the main body 501, particularly the opening of the main body. In the illustrated embodiment, the dispensing device includes a dispensing pump 503 that is manually activated by a push button 504.

  The pump 503 includes a main body 505 provided with means for supplying a substance. In the figure, the supply means includes a plunger tube 506 disposed in the upper cavity 502, which includes a valve 507 that allows product (viscous material) to enter the pump 503. The push button 504 is attached to the nozzle 508 of the pump 503, and the pump includes a piston 509 attached around the nozzle to delimit the metering chamber 510 in the body 501. Piston 509 allows supply orifice 511 of nozzle 508 to open or close the discharge stroke or the respective suction stroke of the nozzle.

  The push button 504 includes an upper region that allows a user to apply finger pressure to the push button so that it can move axially over its stroke to operate the pump 503, and the push button Returning 504 over its suction stroke is accomplished conventionally by spring 512. In the illustrated embodiment, the interior of the body 505 of the pump 503 includes an extender 513 against which the lower end of the spring 512 abuts.

  The push button 504 includes a head 514 that is configured to radially distribute the product. However, the present invention is not limited to a specific method of discharging a product.

  The dispensing method is such that the reservoir is in communication with an air inhalation device and the device is activated to create a negative pressure in the empty product reservoir before the upper cavity 502 is initially filled with product. To do.

  According to one embodiment, the air inhalation device includes a vacuum bell in which the discharge mechanism 505 is disposed, and the sealed attachment of the removal device 503 to the body 501 is achieved after activation of the bell. Accordingly, a negative pressure is created in the upper cavity 502, and then the removal device 503 is sealed and attached to maintain the negative pressure.

  According to another embodiment, an air suction device, such as a vacuum pump, communicates with the removal device 503 after the removal device 503 is sealed and attached to the body 501, and suction of air from the upper cavity 502 is performed as described above. This is done through the picking device. In a variant, air can be aspirated through the refill mechanism by communicating a refill mechanism (not shown) with the air suction device after the take-out device 503 is sealed and attached to the body 501. .

  In the discharging method, the source is then sealed and communicated with the upper cavity 502 by a refill mechanism so that the reservoir is filled by suction of the product contained in the product source by negative pressure. By filling the upper cavity 502 first. The customer can then activate the picker 503 to dispense the contained product.

  By depressing the refill mechanism once to open a refill mechanism valve to form a product transfer path between the product source and the upper cavity 502, and in some cases the non-refillable dispenser The pump can be opened. Filling is then possible by offsetting the negative pressure. Next, when the upper cavity 502 is filled, the suction negative pressure becomes zero, the valve of the refill mechanism is then closed, and the product contained in the upper cavity 502 is subsequently discharged by the take-out device 503. Can do.

  Thus, the 500 supplied to the seller can be free of product and has a negative pressure which causes the customer to purchase and / or test, in particular according to the product he wishes to purchase and / or test. At the time of handing 500 to the customer, the first filling can be performed subsequently. This method therefore allows a particularly versatile initial filling, which in particular allows easy management of the dispenser 500s, in particular the sample test dispenser 500s, by the vendor.

  The versatility of the dispensing method can also be improved by providing a label associated with the body 501 according to the product when the upper cavity 502 is initially filled with the product. The label may have a separable part that specifically includes a sales offer to the merchant to encourage the customer to purchase back to the sample product.

  With reference to FIGS. 9 and 10, the removal devices of embodiments 500 and 600 are of the airless type that does not take air into the upper cavity as an offset of the volume of product to be dispensed. For this reason, the main body 505 of the pump 503 of the embodiment 500 does not have a vent hole.

  However, pumps with vents are most common, so it may be advantageous to create a negative pressure in the upper cavity even with this type of pump. To this end, as shown in the embodiment 600 of FIG. 10, the body 605 is provided with a vent 626 that is sealed within the rigid body 601 for closure (FIG. 10a). . In particular, in this case, the vent 626 seals at least below the mouth between the body 605 and the rigid body 601 so as to prevent air from passing from the pump 603 into the upper cavity 602. In FIG. 10, a seal has also been achieved over the vent 626, which is slightly easier to achieve without entrapment of air and without loss of function.

  The product sample makes it possible to create a negative pressure in the upper cavity 602 that rises with discharge without taking air into the upper cavity 602. In particular, to ensure that the upper cavity 602 is completely emptied, the ceiling of the air above the product during the first filling will have a negative pressure that is reached at the end when emptying is at most Must be equal to the negative pressure achievable by pump 603.

  In this embodiment, the discharge method is in this case a product source (non-refillable dispenser) by a refill mechanism so that the upper cavity 602 is filled by suctioning the product contained in the source by negative pressure. ) In sealed communication with the upper cavity 602 to allow subsequent filling of the upper cavity 602.

  With reference to FIGS. 11 and 12, the product is removed by drawing air into the upper cavity to prevent subsequent filling of the upper cavity by suction. For this purpose, the pump includes a vent configured to allow the volume of the product extracted into the upper cavity by air to be offset.

  11, the pump 703 of the embodiment 700 is mounted in the main body 701 by a sleeve 727, and the main body 705 is mounted in the sleeve so as to be sealed. The vent 726 is a body that is radially opposed to the increased diameter 727a formed in the sleeve 727 so that the mouth remains open to allow air to be taken into the upper cavity 702. 702 (FIG. 11a).

  According to one embodiment, the dispensing method can attach the removal device to the body in the storage position before the product is initially filled in the upper cavity, where the airtightness of the upper cavity is enhanced and the removal is performed. The device is subsequently moved to the discharge position. This means that at the discharge position, the static air tightness of the upper cavity with negative pressure, in the presence of a vent, may not be sufficient to ensure that this negative pressure is maintained at the end of long-term storage. It is because there is sex.

  In addition, the refill mechanism can be reversibly covered by a sealing cap (not shown) to further improve the maintenance of negative pressure over time. The cap can be welded to a recess formed in the free end of the trim (not shown) to completely cover the refill mechanism and has a free edge that allows it to be withdrawn for initial filling purposes. Have.

  11 and 12, the pump 703 is located between an upper storage position (FIG. 12) where the vent is closed and a lower discharge position (FIG. 11) where the vent 726 can freely take in air. It is attached so that it can slide with respect to the main body.

  In particular, the body 703 is mounted within the sleeve 727 by a suitable clamp to allow sliding, and the passage between these positions depresses the push button 704 when the pump 703 is first activated. Is achieved. The sleeve 727 has an upper diameter 727c that seals and attaches the body 705 to close the vent 726, and a step 727b that delimits the increased lower diameter 727a that leaves the vent open. The pump body has a stop 729 for terminating the sliding stroke in the sleeve 727.

  The sub-pressure can facilitate refilling of the dispenser 700. Such embodiments are more useful when the material is not excessively viscous, such as various lotions. Shaking the lotion immediately before refilling (and possibly reducing the viscosity) can facilitate refilling in such cases.

  Since some creams and lotions and colloids may undergo precipitation, agglomeration, etc., solid separation is undesirable for both the applied product and in some embodiments may interfere with the operation of the dispenser. In this case, it may be advantageous to shake the dispenser just before dispensing. In such cases, excessive shaking would not be wise because shaking can cause the viscosity of the viscous material to drop excessively. Some experimentation may be required to produce the most desirable results both in terms of material quality and a more satisfactory operation of the dispenser. Some embodiments may be more suitable for certain types of viscous materials.

  Returning to FIG. 1, the upper portion of the gasket 105 is bullet-shaped, that is, the upper portion is narrowed like a part of the upper cavity 114, making it easy to empty the bottle 111 of the viscous material 7. Be noted. The upper portion of the gasket 105 can generally conform to the shape of the upper portion of the upper cavity, so that the gasket 105 can easily reach the top of the upper cavity 114 and substantially fill the contents of the viscous material bottle 111 if desired. Can be exhausted. However, in other embodiments, the top of the bottle 111 is not bullet-shaped. Further, the gasket is preferably flexible so that in embodiments having a bullet-like upper cavity, the gasket may be able to easily move to conform to the shape of the upper wall of the upper cavity.

  The examples described above show various selected embodiments of refillable cream dispensers. It should be noted that further embodiments are foreseen that also fall within the scope of the invention. The scope of the present invention is defined by the claims, and upon reading the foregoing description, those skilled in the art will recognize a combination of the various features described above and combinations of combinations described above, and combinations thereof. These modifications and modifications are both included.
