A sealed device (1) for protecting and dispensing pasty or creamy products (7), includes a reservoir (2) containing the product (7) and suitable for receiving, at the bottom end thereof, a longitudinally movable sealing plug (3). The reservoir (2) is longitudinally movable like a piston in a pump body (4) and it is forced into the closed position by a spring element (5) that cooperates in compression with a lateral outer projection (2e) of the reservoir (2) and with the top of the side wall (6b) of the base (6) attached to the pump body (4). The pump body (4) includes an elastically deformable upper membrane (4a) providing a pump function and also includes, on an upper lateral wall thereof (4c), a lateral opening (4e) for dispensing the product (7). The assembled reservoir (2) and pump body (4) form a system suitable for circulating the product (7) via a compression chamber (C) supplied from the reservoir (2) by at least one upper inlet orifice (2b). The device is particularly suitable for the hygiene, pharmacy and cosmetics fields.
A device (1) for protecting and distributing pasty or creamy products (7), said device comprising a reservoir (2) adapted for containing the product (7) and adapted to receive at a lower end a sealing plug (3) movable longitudinally, said reservoir (2) movable longitudinally as a piston along a path (Y) in a pump body (4), wherein the reservoir is constrained in a closed position by a spring which cooperates between the reservoir (2) and the pump body (4), and wherein the reservoir (2) comprises an outer projection (2d) formed on a lateral wall (2c) of the reservoir (2) and complementary to a lateral opening (4e) in the pump body (4) from which the pasty or creamy product is dispensed, wherein the outer projection provides a closure of the lateral opening (4e) that lacks any external cavity.
A device for distributing an associated creamy product, said device comprising:
A device (1) for protecting and distributing pasty or creamy products (7), said device comprising a reservoir (2) adapted for containing the product (7) and adapted to receive at a lower end a sealing plug (3) movable longitudinally, said reservoir (2) movable longitudinally as a piston along a path (Y) in a pump body (4), wherein the reservoir is constrained in a closed position by a spring which cooperates between the reservoir (2) and the pump body (4), wherein the spring is operably located between and cooperates in compression between a lateral external projection (2e) of the reservoir (2) and a top of a side wall (6b) of a bottom (6) secured to the pump body (4), wherein the bottom (6) comprises at least one outer projection (6c) that is complementary to and received in an inner groove (4g) of the pump body (4) whereby the bottom (6) is secured to the pump body (4).
