Device for protecting and dispensing pasty or creamy products

Abstract

The invention provides a sealed device (1) for protecting and dispensing pasty or creamy products (7), characterized in that it mainly consists of a reservoir (2) containing the product (7) and suitable for receiving, at the bottom end thereof, a longitudinally movable sealing stopper (3), said reservoir (2) is longitudinally movable like a piston in a pump body (4) and wherein 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) is formed of an elastically deformable upper membrane (4a) providing a pump function and also, on the upper lateral wall thereof (4c), of a lateral opening (4e) fordispensing the product (7). The assembled reservoir (2) and pump body (4) form means suitable for circulating the product (7) via a compression chamber supplied by at least one upper inlet orifice (2b). The device is particularly suitable for the hygiene, pharmacy and cosmetics fields.

Description

technical field [0001] The present invention relates to a device for protecting and dispensing pasty or creamy products such as cosmetic creams, toothpaste, shaving cream and shaving gel, and any other product of similar consistency, the It is particularly simple and economical to produce and ensures perfect protection of the product to be dispensed, especially when it runs out due to insufficient roughness of the outer surface of the product. Background technique [0002] Devices are known for protecting and dispensing pasty or creamy products, such as flexible tubes for toothpaste or sunscreen, which can be deformed by squeezing in order to remove the product to be dispensed. [0003] The main drawback of this type of equipment is that air is introduced into the tubes during application, therefore, it is necessary to add preservatives or antioxidants to the composition of the product to be dispensed in order to prevent it from oxidizing due to contact with air.

Problems solved by technology

[0007] A disadvantage of the existing apparatus associated with a container and a pump subassembly is that it is complex, expensive and bulky, since the pump subassembly consists of multiple parts, which may be plastic or metal , such as springs and balls, which keep the container airtight when the product to be dispensed flows out

This type of equipment is very complicated to design, especially the design of the airtight valve at the product outlet, and a huge amount of money is required in the manufacturing process

Recycling of materials is costly as equipment is difficult to disassemble and sometimes impossible to recycle
