A pump system (100) including an overtube adapter (140) and an overtube (150) attached to the overtube adapter (140), the overtube (150) capable of being selectively attached to the overtube adapter (140) to provide different overtube (150) aesthetics for pump systems and fragrance products.

A fluid dispenser device comprising: a reservoir (1) including a neck (12); a dispenser member (2) that is mounted in the neck (10), the dispenser member (2) being provided with a dip tube (23); and a cover tube (5) that surrounds said dip tube (23); the fluid dispenser device being characterized in that, in the proximity of its connection top end (52), said cover tube (5) includes at least one vent (55) having a total flow section (St) that presents a size that is sufficient to enable the fluid to rise in the cover tube (5) while the cover tube is being inserted quickly into the fluid reservoir (1) in the filled state, without being significantly disturbed by the air that is evacuated from the cover tube (5) through said at least one vent (55).

A method of making a dip tube for a liquid spray pump dispensing apparatus configured to provide substantial invisibility when disposed in a liquid fragrance product. To overcome the challenges of the prior art single layer dip tubes, a two-layer starting tube is provided. A first layer of the starting tube is made of a transparent (invisible in the liquid fragrance product) thermoplastic nonfluoropolymer, while a second layer of the starting tube is made of a dissolvable polymer. After assembly with the liquid spray pump dispensing apparatus, the second layer of the starting tube is dissolved in water or solvent (e.g., ethanol), leaving only the transparent nonfluoropolymer first layer as the dip tube. The thickness of the single layer dip tube can thus be reduced to enhance invisibility, with the dissolvable layer providing sufficient flexural strength for rigidity and desirable handling characteristics to the tube for required assembly to the pump assembly. The remaining single layer dip tube can then perform within the desired use/application (e.g., non-reactive to the fragrance and able to withstand repeated pumping for dispensing the fragrance.
