BOTTLE AND REFILL

Abstract

A refill cartridge and a bottle to contain the cartridge. The refill includes at least two sealed openings, one at the top and one at the bottom. They may be sealed by an in mold label. The bottle is suitable for including the cartridge and may also include a pump and a dip tube. The dip tube is used to pierce the top and bottom seals of the cartridge when the bottle closure is screwed onto the bottle. Piercing the bottom seal releases product into the water filled interior of the body of the bottle. Typically the product will be a concentrate such as a body wash or hand washing concentrate. The bottle preferably includes an aperture or window through which at least a portion of the cartridge can be seen so that the consumer can determine which variation of product is present in the refill in the bottle.

DETAILED DESCRIPTION OF THE INVENTION

[0033] Bottle 10 (FIGS. 1-4) includes body 12, closure 14 and pump head 16. An aperture or window 18 is disposed in closure 14, as will be discussed hereinafter. Body 12 is received in bottom sleeve 20. Sleeve 20 protects the bottom of the bottle from damage such as scuffs, scrapes and denting. It may be made of silicone. The bottle may be made of suitable plastic such as high density polyethylene, although to minimize plastic use it may advantageously be fabricated from stainless steel or aluminum. The pump and bottle closure may be made of high density polyethylene. Other materials of which the bottle could be made include glass and polyethylene terephthalate.

[0034] Cartridge 100 (FIGS. 7-15) comprises body 102 and closure 104. Closure 104 includes opposed flaps 108 depending therefrom. Closure 104 includes closing platform 150 and an opening 152 defined by an inner cylindrical wall 154 (see e.g., FIG. 12) and sealed by in mold label (IML) seal 106. Outer cylindrical wall 117 having external protuberances 116 depends from platform 150. The cartridge may be made of high density polyethylene, and the IML may also be made of high density polyethylene. The IML must be made of a material which can be opened by the dip tube, with or without door 170. Other materials such as polypropylene may be suitable for the IML, depending on the barrier properties desired. The IML could also be multilayer of the same or different materials.

[0035] In general, product will be placed in the body of the cartridge by the manufacturer, who will secure the cartridge closure 150 to the cartridge, as by screwing or snapping them together. In the embodiment shown in FIG. 12 depending wall 117 has external protuberances 116 which are snapped into internal detents 160 inside the upper end of the body of the cartridge to secure the cartridge closure to the cartridge. Of course, other structures may be used to secure the cartridge closure to the cartridge. Flaps 108 extend downwardly along the outside of the cartridge from the top of the closure.

[0036] Preferably, the manufacturer will provide the bottle to the consumer with pump, bottle closure and dip tube attached as shown in FIGS. 16 and 17. As best seen in FIG. 18, support prong 62 within bottle closure 14 is accommodated within clips 62 on the pump stem 92 to help secure the pump in the closure. The pump may be secured within the bottle structure using ribs, gaskets, or plastic.

[0037] The bottle may be provided with a first cartridge already in place, or the bottle may be empty of a cartridge. Assuming there is no cartridge in the bottle, or the cartridge is spent and has been removed, when ready to use the product, the consumer will remove the closure/pump/dip tube from the bottle and place water within the body of the bottle. Then the consumer inserts the cartridge into the bottle with ledge 200 (FIG. 12) of the cartridge resting on bottle neck 30. Flaps 108 extend downwardly from closure 104 on the outside of the neck 30.

[0038] The combined bottle closure/pump head/dip tube shown in FIGS. 16 and 17 are then put in place. Closure 14 is screwed onto the bottle with external screws 32 on the bottle neck mating with internal screws 90 on the bottle closure (see FIG. 19). This secures the cartridge within the bottle. Dip tube 24 is beveled at 26 to facilitate penetration of seal 106 (FIG. 12) to permit the dip tube to enter into the cartridge through the opening 152 in the closure of the cartridge and then to push open door 170 in the bottom of the cartridge which then pushes open seal 140 beneath the cartridge to permit product to escape from the cartridge into the water-filled body 12 of the bottle. Door 170 is formed from a generally circular cut 171 in bottom 172 of the cartridge and preferably remains attached to bottom 172 at least at one point 174 which serves as a hinge. While the door 170 is illustrated as generally circular it may be of an suitable shape.

[0039] FIGS. 18 and 19 show the structure of the bottle/cartridge combination once the bottle closure has been closed and the dip tube has been inserted through the cartridge to the bottom of the bottle, except that the door 170 is omitted.

[0040] The relationships among the components of the bottle/refill can be seen in FIG. 6.

[0041] Once the cartridge/refill, pump and bottle closure are in place as seen in FIG. 18, the consumer presses on the pump head to pump the diluted product from the body of the bottle. When the product is depleted, the consumer readily opens the bottle by unscrewing the closure and can then remove pump head/closure/dip tube from the refill the and the refill from the bottle body. The refill can be discarded, or more preferably, recycled, and another one inserted.

[0042] When the bottle closure 14 is screwed onto the bottle, flaps 108 are received beneath the bottle closure, between the closure wall and the neck 30 of the bottle. In accordance with one feature of the invention, aperture or window 18 in the bottle closure is positioned so that when the closure is closed, the aperture will permit viewing of all or part of one or more of the flaps 108. If a window is used instead of an aperture, it may be a transparent or translucent plastic. Thus, the consumer can see part of the flap even though the bottle is closed. This permits the consumer to know which refill is present in the bottle if appropriate indicia such as color are present on the flaps. Alternatively, the one or more apertures or windows can be placed in the body of the bottle in addition, or instead of, the one in the closure, as long as a part of the cartridge will be visible from outside the bottle.

[0043] While the cartridge has been illustrated as having a sealed opening at the top and a sealed door at the bottom, other arrangements permitting insertion of a dip tube through the top and bottom may be possible. For instance, one or both may have a closure such as a flip top, which could be opened by consumers prior to insertion of the cartridge into the bottle. Thus, the cartridge will have a closed area at its top which will accommodate passing through of a dip tube, either through lines of weakness, which may be sealed, or sealed opening or reversible opening, and a closed area at the bottom which will a dip tube can open either through a cut or lines of weakness, which may be sealed, or sealed opening or reversible opening.

[0044] Suitable pumps may be obtained from Rieke Corp. of Auburn, Ind. Suitable stainless steel bottles may be obtained from S′well Bottles of New York, N.Y. Suitable in mold labels may be obtained from CCL Industries of Shelton, Conn.
