Definitions
- the present invention relates to shielding water bottles of the type normally three to five gallons capacity which are placed in inverted fashion over a water dispenser in offices, factories, homes, restaurants, and other locations.
- the subject water bottles are normally prized by the manufacturers based upon the cleanliness and purity of the water which they contain. After the bottle is filled, a cap is applied to it, and the contents sanitarily sealed.
- the bottles when the bottles are stored they invariably are stored with the cap up.
- the area below the cap and the shoulder are the very areas which, when the bottle is inverted for use in the water dispenser, come in contact with the upper cup of the dispenser and its insides.
- the contamination which befalls the bottle after it leaves the sanitary bottling works is all on the very area which is exposed to the dispenser and its cup and dispenses directly into the stream for the unwitting user.
- the contaminants can be loosened by the handling while inverted, and indeed, if the bottle is dropped in inverted fashion into the dispenser the impact will serve to dislodge even more of the contamination.
- the present invention stems from the discovery that a disposal sleeve or shield can be applied to a water bottle before leaving the filling source, heat-shrunk or otherwise caused to take the configuration of the upper portion of the bottle including the cap, and shoulder, and anchor the same to the bottle.
- the cover which has a neck, shoulder, and body portion to conform to the bottle can be provided with a removal tab upper portion.
- the securing of the sleeve to the bottle in an intimate skin-to-skin relationship which thereby shields the upper portion of the bottle from contamination wherever it may be prior to use. Because the heat-shrink occurs at elevated temperatures of 350°F or more, bacteria are killed in the process.
- the method of the invention resides in heat-shrinking or other wise securing a protective sleeve over the top of a water bottle. This is accomplished by forming a tube of a diameter larger than the bottle, cutting and forming the sleeve, positioning over the bottle neck and shoulder, and then heat-shrinking at a temperature exceeding that of boiling water. Thereafter, in accordance with the method, the sleeve is removed prior to emptying the bottle, the bottle then uncapped, and then secured to the cooler. The body of the sleeve is desirably removed before the bottle cap is removed. What is important, however, is to physically observe the removal of the sleeve to the end that the contamination which may have adhered to the outer portion of the sleeve is discarded rather than being permitted to engage any portion of the water bottle or the dispenser.
- a related object of the present invention is to provide such a sanitary sleeve for a water bottle which is not only easily applied to the bottle, firmly attached to the bottle, but also easily removable at the site of installation of the bottle to the dispenser.
- Another important object of the invention is to achieve and extend the sanitary processing of the water in the bottle by applying a sleeve to the upper portion of the bottle which, because it is heat-shrunk onto the bottle at a temperature exceed 350°F, will further ensure the inhibition of residual bacterial activity on the exterior portion of the bottle adjacent the area from which the water will be dispensed.
- a correlative advantage results from using an air impervious material to thereby kill any aerobic bacteria, or alternatively inhibit the passage of same to the inner face between the sleeve and the bottle itself.
- a further important object of the present invention is to provide a sanitary upper sleeve for a water bottle which is relatively inexpensive compared to the total cost of the bottle and susceptible of alternative constructions and applications to the bottle.
- FIG. 1 is a perspective view of a typical three to five gallon water bottle for use on a dispenser
- FIG. 2 is an exploded perspective view of the bottle, bottle cap, and importantly the sanitary sleeve of the subject invention
- FIG. 3 is a vertical transverse section, in enlarged scale, taken along section line 3-3 of FIG. 1 ;
- FIG. 4 is a front elevation of the sanitary sleeve
- FIG. 5 is a transverse vertical sectional view of the sleeve shown in FIG. 4 taken along section line 5-5 of FIG. 4;
- FIG. 6 discloses an alternative embodiment of the cover illustrating a tab for removing the same
- FIG. 7 shows the removal of the sanitary cover without a tear tab or line of weakness by pulling it off of a top of a bottle, much in the same fashion as one would remove a sock;
- FIG. 8 is yet another alternative embodiment showing lifting the sanitary sleeve off utilizing an optional tear tab and also an optional line of weakness;
- FIG. 9 is a diagrammatic view of a tube being fed onto a conveyor line for subsequent forming into the sleeve for the bottle;
- FIG. 10 is a sequential view from FIG. 9, showing how the sleeve is cut to remove a portion leaving the blank remaining for placing over the bottle;
- FIG. 11 is yet a sequential view showing the sleeve over the bottle loose fittingly engaging the same;
- FIG. 12 is a final diagrammatic view of the bottle being passed through a heat chamber which will cause the sleeve, at an elevated temperature of 350°F desirably, to shrink itself onto the bottle and at the same time sterilize from bacteria and subsequently shield against the growth of aerobic bacteria which may be trapped between the sleeve and the bottle.
- the invention is best described in its environment of a water bottle 10, such as shown in FIG. 1.
- the bottle invariably has a cap 11 which is press fitted to the bottle neck 12. Beneath the neck 12 is a shoulder 14 followed by a barrel-shaped bottle body portion having a plurality of ribs such as ribs 15 and 16.
- the upper rib 15 becomes the important part of the anchor for the sanitary sleeve 20 of the present invention.
- the bottle bottom 18 is at the opposite end of the application of the sanitary sleeve.
- the bottle is provided with a tab 19 on the cap 11 for the removal of the bottle cap.
- FIG. 2 The sequential relationship between the bottle 10, the bottle cap 11 , and the sanitary sleeve 20 is shown in FIG. 2.
- FIG. 3 in enlarged detail it will be seen that the sleeve 20 has been secured over the upper portion of the bottle 10 to follow the contour of the cap 11 , the neck 12, the shoulder 14 and to engage itself in a skirt-like gripping relationship to the upper rib 15 of the bottle 10.
- the sleeve 20 has a top portion 21 and a bottom portion 22 with a bell-shaped seam 24 joining two opposed sheets of material as shown in FIG. 5 defining an interior portion 29.
- the front 26 and rear 28 are shown in FIG. 5.
- FIG. 6 there is a showing of the sleeve 20 with a tear-line 30, and an optional tab 31 thus defining a removable cover 32 as shown in FIG. 8.
- the lower portion may be removed before the upper portion of the sleeve to thereby isolate the bulk of the contaminants from the bottle top before the bottle cap 11 is removed.
- the simplest approach to the removal of the sanitary sleeve 20 is to grasp it at the bottom edge 22, and remove the same from the upper portion of the bottle in much the same fashion as removing a sock from the foot.
- FIG. 7 the simplest approach to the removal of the sanitary sleeve 20 is to grasp it at the bottom edge 22, and remove the same from the upper portion of the bottle in much the same fashion as removing a sock from the foot.
- FIG. 8 shows yet another alternative embodiment in which optionally either a tab 31 is provided at the upper portion of the sleeve 20, or a line of weakness 30 is provided along a vertical edge.
- the thrust of the invention is directed to totally encapsulating the upper portion of the bottle 10 with a removable sleeve 20, with variations as to how the same is applied and as to how the same is removed
- the material employed for the sanitary sleeve 20 is desirably heat-shrinkable, compatible with food and drug regulations, tough and durable to withstand the type of handling that the water bottle 10 will have.
- a material is exemplified by the DuPont product known as Clysarwhich is a shrink package film. It is available in gages 60, 75, 100, 125 and 150, either flatorfolded. More specifically, it is described as strong, clear, biaxially oriented, heat-shrinkable, and comprised of a linear low density polyolefin film.
- the product can be obtained from the DuPont packaging group at 1007 Market Street, Wilmington, Delaware 19898.
- Plastics recommended for use are the following:
- Rigid Plastics can be: a. extruded b. molded c. vacuum-formed.
- Semi-Rigid Plastics can be: a. wax or wax based products b. spray base application.
- Flexible Plastics can be: a. stretch - saran factor b. elastic - latex c. heat-shrink - polyolefin, PVC film of 1 mil. (.025 gauge), LD & HD polyethylene other latex, petroleum, polymer, resin, natural, organic or synthetic based materials commonly referred to as "plastics".
- the dwell time in the heat-shrink area is 3-5 seconds at 350-400°F.
- Exemplary of the bottles are the Reid "Aqua-Lite" round water bottles. They come primarily in three and five gallon capacities. More particularly, they have protruding ribs encircling the body portion such as rib 15, as shown in FIG. 7. Alternatively, the rib 15 may be conc.-i.vely, formed in the bottle. In either event, the important aspect of use is to heat-shrink the lower edge 22 of the sanitary sleeve 20 onto the bottle 10.
- the method of the invention contemplates primarily developing a sleeve 20 for encapsulating the upper portion of a water bottle 10 which is proportioned so that its lower edge overlaps the first rib 15 of the bottle.
- the sleeve 20 After the sleeve 20 is placed over the bottle, it is heat-shrunk or otherwise shrunk to conform in a skin-tight relationship to the bottle essentially as shown in FIGS. 3 and 6. Thereafter, the method contemplates the step of removing the sleeve cover and the sleeve body portion from the bottle prior to inverting the bottle over the dispenser where employed. Desirably, the sleeve 20 should be wiped with a damp cloth or other cleansing technique prior to being removed to thereby further ensure that the handler of the bottle does not indulge in cross-contamination.
- the method contemplates the use of a pair of opposed sheets of DuPont Clysar, or alternatively a tube 35, the diameter of which exceeds the bottle 10, a distance sufficient to permit the same to be shaped into a circular form and dropped over the bottle, such as shown in FIG. 9. Thereafter, as shown in FIG. 10, the tubular form is cut at its upper corners in order to develop a smaller area to pass over the neck and the cap of the bottle.
- the sleeve is then dropped over the bottle totally surrounding the same and dropping below the shoulder portion of the bottle, with the neck of the sleeve resting atop the bottle cap.
- the bottle is passed into a heat tunnel 40 desirably held at a temperature of 350°F.
- blowers are provided to heat the sleeve portion to a temperature elevated from that of the ambient in the tunnel.
- the curing time for the material to shrink into a skin-type relationship is approximately 3-5 seconds. This dwell time does not significantly increase the temperature of the contents of the bottle, but is rather concentrated on the sleeve to promote its shrinkage.
- ultra-violet and/or infrared may be applied to the material, depending upon its characteristics and shrink promoting properties.
- Alternatives of the method are contemplated, but basic to the method is heat- shrinking the sleeve into place for the insurance of a skin-tight fit, and the application of a temperature which will enhance the sterile relationship between the inside of the sleeve and the upper portion of the bottle.
- An alternative includes the preforming of the sleeve by a hot knife application to two sheets of the material.
- a tubular form of the material can be heated ' at the upper area and stretched which thereby reduces the neck portion for conformance to the neck of the bottle.
- Alternatives are also contemplated including an under-sized sleeve 20 which is expanded with pure or inert air or otherwise expanded prior to pulling over the bottle 10 and then conforming to the shape of the bottle as the opening force is relaxed.
