Abstract
Description
- This invention relates to viscous liquid dispensers and, in particular, to a dispenser containing at least two disposable cartridges of the viscous liquid with means for selectively dispensing only from a single cartridge at any one time.
- Within the past ten years, it has become fairly common to package certain viscous liquids, such as soaps, shampoos and like products, in disposable cartridges and to dispense such liquids from dispensers in places like public washrooms, and hotel and motel bathrooms. Although the detailed construction of the disposable cartridges may differ, they generally include a compressible pump portion and an exit orifice for the liquid. When pressure is applied to the pump portion of the cartridge, liquid is forced through the exit orifice, into the user's hand. The dispensers that accept such disposable liquid cartridges have a manually operated dispensing member, such as a pivoted lever, for pressing the pump portion of the cartridge against a compression surface in the dispenser. A typical prior art viscous liquid dispenser is disclosed in U.S. Patent 4,130,224-Norman, et al., assigned to the assignee of the present invention. The dispenser of Norman, et al. is used to dispense liquids such as soap from a single disposable cartridge. The Norman, et al. dispenser has a sight window located adjacent to the bottom of the disposable cartridge so that a maintenance person can see that the cartridge needs to be replaced. One problem with the single cartridge dispenser is that when the maintenance person looks at the window, the level of the fluid may be only slightly above the window with the result that the cartridge is completely used up before the maintenance person returns to service the dispenser. Another common occurrence is that if the maintenance person observes that the liquid level in the cartridge is just below the top edge of the sight port, the maintenance person may replace the cartridge rather than take the chance that the cartridge will empty before the dispenser is next serviced. This, of course, can lead to a considerable waste of the liquid soap or other product. Thus, it would be desirable to have a dispenser that holds two disposable cartridges so that the user can completely exhaust one cartridge and then begin immediately dispensing from the second cartridge.
- One approach for dispensing from two cartridges is suggested by U.S. Patent 4,513,885-Hogan which discloses packaging two single cartridge dispensers side by side to form a dispensing system. One problem with adopting this concept for a liquid soap dispenser is that since the user can dispense from either dispenser it is possible for both cartridges to empty at the same time. Thus, it can be seen that it would be desirable to have a dual cartridge dispensing system which prevents the user from dispensing from one cartridge until the other cartridge is completely empty.
- U.S. Patent 2,619,386-Dalrymple discloses a trigger operated spray gun for simultaneously spraying two liquid solutions onto an object. At
column 5, lines 49-68, Dalrymple describes a trigger operated mechanism that simultaneous opens or closes a pair of fluid passages. Atcolumn 6, lines 33-40, Dalrymple provides for individual adjustment of the fluid flow through each fluid passageway. - It is an object of this invention to provide a dispenser for two or more disposable, viscous liquid cartridges wherein the probability that the dispenser will empty before it can be serviced is greatly reduced.
- Another object of this invention is to provide a dispenser, having two disposable liquid cartridges, that can only dispense from one cartridge at a time.
- While the specification concludes with claims particularly pointing out and distinctly claiming that which is regarded as the present invention, the objects and advantages of this invention can be more readily ascertained from the following description of a preferred embodiment when read in conjunction with the accompanying drawings in which:
- Fig. 1 is a perspective view of the dual liquid cartridge dispenser of this invention; Fig. 2 is a front elevational view of the dispenser;
- Fig. 3 is a front sectional view taken along the line 3-3 of Figs. 1 and 4;
- Fig. 4 is a sectional side elevation view taken along the line 4-4 of Figs. 2 and 3;
- Fig. 4a is a partial sectional side elevation view illustrating the compression of the cartridge pump assembly;
- Fig. 5 is a partial sectional view taken along the line 5-5 of Fig. 4; and
- Fig. 6 is a sectional view taken along the line 6-6 of Fig. 5.
- In accordance with the invention there is provided a dispenser that can support two disposable liquid cartridges, each cartridge having an exit orifice through which fluid is dispensed when a pump portion of the cartridge is compressed. The dispenser has a movable compression member located in the apparatus having a first position adjacent the pump portion of the first cartridge and having a second position adjacent the pump portion of the second cartridge. The movable compression member is connected to a knob extending outside the dispenser which is used to move the compression member to the first position or to the second position to thereby select the cartridge that is compressed. The dispenser has a movable dispensing member which compresses between the compression member and an opposing pinch surface in the dispenser only that cartridge pump portion that is adjacent the compression member.
- For the sake of convenience, an element depicted in more than one figure will retain the same element number in each figure. Referring now to Fig. 1, the
dispenser 10 of this invention has arear base member 12, afront face 20, atop wall 22,bottom wall 24 andside walls base 12 is provided with a number of mounting holes, not shown, so that it can be mounted by means of bolts to a wall behind a washroom sink. In a preferred embodiment, thefront wall 20,top wall 22,bottom wall 24, andside walls dispenser 10 form acover 14 that, as best illustrated in Figs. 4 and 4a, is pivotally connected to thebase 12 by means ofshort hinge pins 30 on thecover 14 which extend intopivot holes 32 insupport member 34 ofbase 12. Also attached to thebase 12 is ashelf 36 for supporting two disposable viscous liquid cartridges 11a and 11b, such as soap or shampoo, side by side in thedispenser 10. - As best shown in Fig. 3, a typical viscous liquid cartridge 11 includes a flexible bag 13, a pump assembly portion 17 and a paperboard box 21 for controlling the shape of the flexible bag 13 both in the
dispenser 10 and during shipment. The pump assembly 17 consists of a connector element 23, a flexible tube 25 having one end connected to the connector 23 and the other end connected to a discharge element 27 which includes exit orifice 15 through which the liquid is dispensed. In a preferred embodiment, the discharge element 27 includes a normally closed, spring loaded, ball valve as described in the aforementioned patent to Norman, et al. As best shown in Figs. 4 and 4a, afitment 19b attached to the bottom of theflexible bag 13b provides an outlet port through which liquid can flow out offlexible bag 13b. Theconnector element 23b ofpump assembly 17b is inserted into thefitment 19b to provide fluid flow from theflexible bag 13b into thepump assembly 17b. The filledflexible bag 13b, and attachedpump assembly 17b are packaged inside the paperboard box 21b for shipment. - Referring now to Figs. 4 and 4a, a
handle 40, or dispensing means, is pivotally connected to thebase 12 by means ofshort hinge pins 42 which extend intopivot holes 44 insupport member 34 just below theshelf 36. Thesupport member 34 has acentral opening 38 and thehandle 40 is mounted so that it extends through thecentral opening 38 with theend 40d spaced a short distance below the bottom of thedispenser 10. Assembled to thehandle 40 is a spring loaded, pivotedpinch block 46.Pinch block 46 has a pair of hooks 46a which fit around abar element 40a ofhandle 40 so that thepinch block 46 can pivot around thebar element 40a.Spring 48 mounted between thehandle 40 and thepinch block 46 biases twotabs 46b of thepinch block 46 againstcorresponding stops 40b on thehandle 40. A spring retaining boss 40c on thehandle 40 andspring retaining boss 46d on thepinch block 46 act to retain thespring 48 within the assembly. Assembled to the lower, front part ofsupport 34 is adischarge element holder 50 into which the discharge elements 27 of two cartridges 11 are held. - Referring now to Figs. 4, 4a, 5 and 6, mounted within the
cover 14 is amovable compression block 52. Aslide plate 54 is affixed to thecompression block 52 and aknob 56 to provide a movable compression means. The upper and lower edges ofslide plate 54 move in slide tracks formed betweenhorizontal guide walls 58 andinner surfaces 62 ofcover 14. As best shown in Fig. 5, the sloping side 66a ofledge 64 cooperate with a raised projection 52a on theupper edge 52c ofcompression block 52 to fix the location of thecompression block 52 adjacent to theflexible tube 25b of cartridge 11b. When a force is applied to theknob 56 in the direction ofarrow 68, the sloped side 66a applies a compressive force to projection 52a and, because ofslot 52b, theupper edge 52c of thecompression block 52 yields to allow the projection 52a to slide alongledge 64. When the movable compression means reaches the position represented by thedashed lines 70, the projection 52a rides up thesloped side 66b which retains themovable compression block 52 in a second position adjacent the flexible tube 25a of the pump assembly 17a of the other cartridge 11a. - Referring now to Figs. 1 and 2, the
dispenser 10 has aviewing window 72 located in the center of thefront face 20 of the dispenser. Theviewing window 72 is located aboveknob 56 and even with the lower portion of the cartridges 11a and 11b supported in thedispenser 10. As best shown in Fig. 3, each box 21 has two small rectangular cutouts 29 at the front lower corners of the box 21. When the cartridge 11 is placed in thedispenser 10, the bottom of the flexible bag 13 of the two cartridges 11 are visible through theviewing window 72. - A typical operating sequence will now be described. The
cover 14 is unlocked, or unlatched as the case may be, and pivoted down about hinge pins 30. Spent cartridges 11 are removed and replacement cartridges 11 are prepared by tearing out the vertical front wall strips 31 and the bottom wall strips 33, shown in Fig. 3, from cartridge boxes 21. Removal of those strips 31, 33 allows the pump assemblies 17 to be withdrawn from the boxes 21 so that they extend down from the lower left or lower right portion of the box 21 depending upon whether the cartridge 11 is placed on thesupport shelf 36 in the left or right position. As best shown in Fig. 4, therear wall 12 ofdispenser 10 has two locatingbosses 74 which fit into a locating hole 35 in the cartridge box 21 so that the two cartridges 11a and 11b are precisely positioned in the dispenser. Locatingbosses 74 also prevent shifting of the cartridges 11a and 11b in thedispenser 10 when replacing cartridges. The discharge element 27 of each cartridge 11 is placed into thedischarge element holder 50. As best shown in Fig. 3, when thedischarge elements lower edge 40d of thehandle 40. - The
cover 14 is now pivoted upward to close thedispenser 10. With theknob 56 placed to the right as shown in Fig. 2, themovable compression block 52 will be located adjacent thepump assembly 17b of cartridge 11b. Dispensing of the fluid from cartridge 11b commences by a user placing his hand palm upward with his fingertips behind thehandle 40 and movinghandle 40 in the direction indicated byarrow 41 in Fig. 4. Ashandle 40 is moved to the position indicated in Fig. 4a,pinch surface 46c ofpinch block 46 first pinches the upper portion offlexible tube 25b againstcompression block 52 to seal thetube 25b and prevent any back flow of fluid from the lower portion ofpump assembly 17b into theflexible bag 13b. Once the upper portion of theflexible tube 25b has been pinched off, further forward motion ofhandle 40 results inpinch block 46 rotating aboutbar 40a and compression ofspring 48 so thatpinch block 46 builds up fluid pressure in the lower part ofpump assembly 17b thereby causing fluid to be expelled through theexit orifice 15b into the palm of the user. - When the user releases the
handle 40,spring 48 returns thepinch block 46 to the biased position withtabs 46b ofpinch block 46 in contact with stop surfaces 40b ofhandle 40 which causes handle 40 to be returned to the position shown in Fig. 4. As best shown in Fig. 6, when themovable compression block 52 is positioned adjacent theflexible tube 25b of cartridge 11b, there is aspace 76 between the flexible tube 25a of cartridge 11a and the nearest inside wall ofcover 14. Thespace 76, which is the thickness ofmovable compression block 52, is such that the forward motion of thepinch block surface 46c cannot completely pinch off the flexible tube 25a of cartridge 11a and will not cause fluid to be dispensed from cartridge 11a. When a user observes that cartridge 11b is empty, he can moveknob 56 in the direction ofarrow 68 in Fig. 6 to position thecompression block 52 adjacent flexible tube 25a of cartridge 11a. Dispensing from cartridge 11a can now take place. When the maintenance person comes to service thedispenser 10, he will observe through thewindow 72 that the cartridge 11b is empty and can replace it with a new cartridge 11b. - While the present invention has been described with reference to a specific embodiment thereof, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from the invention as defined in the claims. For example, it is possible to mount the spring loaded
pinch block 46 on thecover 14 and themovable compression block 52 on thehandle 40. This could be accomplished by providing thecompression block 52 with a portion that extends behind thehandle 40 and by providing theknob 56 with two arms that extend around and behind thehandle 40 so that the arms move thecompression block 52 from behind thehandle 40 when theknob 56 is moved. Also, although the cartridge 11 is compressed with a first pinching action followed by a compression action, that is due to the design of the pump assembly portion 17. The principles of this invention can be used in dispensers for cartridges 11 that have a pump portion 17 that require only compression to cause dispensing of the fluid.
