Definitions

  • the subject invention concerns an improvement in expendable containers of the kind which are provided with a pump mechanism for dispensing metered quantities of fluids of varying viscosities.
  • the improved container is designed to be used in association with a holder unit of a prior-art kind.
  • the improved container in accordance with the invention is primarily intended for soap solutions and medical preparations.
  • Prior-art containers incorporating mechanisms for dispensing dosed quantities of soap solutions and similar fluids suffer from several drawbacks. They require supervision and servicing, since they often are positioned in premises where they are exposed to heavy wear and frequently also wanton destruction, such as in public lavatories and similar places. Lack of attendance and insufficient cleaning may result in malfunctioning of the device or in bacterial growth. Bacteria that have gained access to the interior of the container are entrained with the fluid dispensed therefrom and thus reach the consumer. As a result, under unfavourable conditions dispensing devices may act as disease carriers, which is quite unacceptable, particularly in hospitals.
  • One prior-art structure designed with a view to remedy the disadvantages outlined above consists of an expendable bag from which fluid is extracted by means of a special arm or by the consumer squeezing a flap formed on the bag.
  • the flap has a dispensing valve welded thereon.
  • the disadvantages of this prior-art structure are multifold. For instance, the bag and the dispensing mechanism are entirely unprotected against wanton destruction. In addition, they are comparatively fragile and as a result thereof are easily damaged when exposed to careless treatment or manipulation.
  • This prior-art structure is also comparatively expensive to manufacture and must be produced in long series since complex tools are required to manufacture this dispenser device.
  • a further disadvantage is that it is difficult to handle on account of its awkward shape.
  • the purpose of the subject invention is to provide an improved expendable dispenser-type fluid container by means of which the drawbacks outlined above are eliminated.
  • This aim of the invention is achieved by forming the expendable container with s shape-resistant dispensing portion and with at least one portion of the container with thin walls to render the container collapsible and exhaustible.
  • the invention also comprises a method of manufacturing the improved container according to which method the container is blow-moulded to the desired shape from an extruded synthetic-resin blank, during which blow-moulding operation the container is formed with at least one thin-walled portion and with one shape--resistant dispensing portion.
  • Fig. 1 shows an expendable container 1 in accordance with the invention
  • the container 1 is intended to be mounted on e.g. a holder unit 2 of a prior-art kind.
  • the container 1 consists of a front portion 3 of a shape--resistant material, of a collapsible portion 4 which extends from the front part 3, and of a dispensing portion 5.
  • the dispensing portion 5 is made of a shape-permanent material and may be of a type known per se.
  • the container 1 is made from plastics and produced in the process known as blow-moulding.
  • Portion 5 is made as an integral part of the container. Because the container is designed to include a filler opening 23 and because the discharge or dispensing portion 5 is positioned close to the front portion of the container this portion will be thicker walled/more shape-resistant than the rear portion of the container. The latter portion thus will constitute a pliant and easily deformable bellows-like container portion which projects from the comparatively rigid base, that is, the front wall of the container, that is portion 3. The portion 4 will collapse/be exhausted through the effects of the partial vacuum created as fluid is dispensed from the container.
  • a through-flow channel 6 leads from the container interior to an outlet opening 7.
  • a lower valve portion 8 in which is formed a valve seat 9. The latter is spaced a certain distance from the outlet opening 7.
  • the position of the valve portion 8 is determined by an interior shoulder 10 formed in the through-flow channel.
  • a groove 11 is formed in the interior face of the valve portion 8.
  • valve mechanism 12 In the groove 11 is mounted a valve mechanism 12.
  • This mechanism comprises a disc 13 on which are secured an upper resilient arm 14 and a lower resilient arm 15.
  • On the outer ends of the arms 14 and 15 are secured respectively valve body 16 and valve body 17, both in the shape of e.g. a sphere.
  • An upper valve portion 18 is inserted into the channel 6 so as to be mounted on top of the lower valve portion.
  • an upper valve seat 19 In the upper valve portion 18 is formed an upper valve seat 19 and a channel 20 communicating a pressure bulb 21 with a void formed between valve seats 9 and 19, this void forming a valve chamber 22.
  • the preferably balloon-shaped pressure bulb 21 forms part of the dispensing portion 5.
  • the arms 14 and 15 urge the valve spheres 16 and 17 with a certain bias force against the respective associated valve seats 19 and 9.
  • the upper sphere is urged upwards while the lower one is pulled upwards.
  • Fluid is filled into the container through the filler aperture 23 and the latter is then sealed, either through welding or by means of a screw cap.
  • the container is manufactured in the following manner. First, a blank of plastics is produced through extrusion. The final shaping is then obtained by blow--moulding the blank into the configuration of the finished container. The dispensing portion 5 is blow-moulded in the very same operation. In connection with the blow-moulding operation the valve components incorporated in the dispensing portion 5 are attached (see Fig. 3). After the extrusion and blow-moulded operations the plastic shrinks somewhat, whereby the positions of the various components are determined permanently in an easy and efficient manner, which also means elimination of all risks of leakage.
  • the improved dispenser-type container in accordance with the invention provides a number of advantages. Empty containers may be stored neatly in a compressed condition, requiring minimum space compared with prior-art shape-resistant containers.
  • the collapsible bellows-like portion 4 of the container collapses gradually as fluid is extracted from the container and the degree of collapse or "squeezed" appearance of the container is indicative of the quantity of fluid that still remains inside the container.
  • This quantity may be easily determined through a window 24 or similar means formed in the holder. This determination therefore may be made without requiring removal of any part of the cover of the container and consequently may be effected in the simplest possible manner.
  • Dispensing or discharge of fluid is effected by compression of the pressure bulb 21 directly or by depressing a push button 25 formed in the holder and acting on the pressure bulb.
  • FIG. 4 Another embodiment of the container which is somewhat modified compared with the one illustrated in Figs. 1 and 2, is shown in Figs. 4 and 5.
  • the expendable container 26 in accordance with this embodiment has a rigid central portion 27 rather like a strap encircling the container. According to this embodiment both the rear and front of the container have thin walls and consequently a double-bellows effect is obtained.
  • a filler aperture 28 corresponding to filler hole 23 in accordance with the embodiment of Figs. 1 - 3 is provided at the top of the central portion 27.
  • On the lower face of the central portion 27 is provided a dispensing portion 29.
  • the container forms two bellows 30, one on either side of the rigid central portion.
  • the dispensing portion 29 differs slightly from the dispensing portion 5 shown in Fig. 3. Portion 29 is provided with two pressure bulbs 31 instead of the single pressure bulb 21 appearing in the embodiment according to Fig. 3. The portion 29 is otherwise provided with a valve inset of an identical type to that shown in Fig. 3 and functions in the same manner.
  • the container 26, shown in Fig. 4 in filled condition and in Fig. 5 in exhausted condition, is mounted in a holder of a kind known p er se. As appears from Fig. 5 the container will occupy minimum space when in its exhausted condition. Obviously, it is possible to form the container entirely without rigid portions except in the areas of attachment of the filler hole and the dispensing portion, in which case the container will assume the appearance of a balloon. The holder must of course in this case be given a corresponding balloon-like shape.
  • the dispensing portions 5, 29 may be designed to fit other containers and dispensers having similar functions. Also, it is of course possible to mount the container according to the invention in other holders than the holder referred to above which is described in the pending Swedish Patent Application No. 8004153-6. It is likewise possible to manufacture the dispensing portions 5, 29 separately and then attach them to the container by welding, screwing or by some other means. However, containers manufactured in this way will be somewhat more expensive than containers manufactured according to the integrated method described in the afore-going.
