Description
- 1. Field of the Invention
- The present invention relates to a film or membrane perforating device, and more particularly to a membrane perforating device for engaging with a film or membrane and for perforating the film or membrane and for allowing air to flow through the film or membrane and for preventing water to flow through the film or membrane.
- 2. Description of the Prior Art
- Typically, for preserving the beverage, the food, particularly the sea food, a film or membrane is required to be provided and engaged onto the outer or upper portion of the cup or receptacle or container that is provided for receiving the beverage or the food, in order to suitably seal the cup or receptacle or container.
- For example, U.S. Pat. No. 4,691,500 to Danforth et al. discloses one of the typical lid sealing machines for applying and sealing lids on the trays.
- Some of the cups or receptacles or containers may be disposed in a microwave oven for heating the beverage or the food contained in the cup or receptacle or container.
- However, if the cups or receptacles or containers are tightly sealed with the lids or films or membranes, a vapor may be generated within the cups or receptacles or containers which may be exploded because the vapor may not flow out through the lids or films or membranes.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional membrane perforating devices.
- The primary objective of the present invention is to provide a membrane perforating device provided for engaging with a film or membrane and for perforating the film or membrane and for allowing air to flow through the film or membrane and for preventing water to flow through the film or membrane.
- In accordance with one aspect of the invention, there is provided a perforating device for perforating a membrane, the perforating device comprising a three-dimension element including a number of particles secured together, and the particles each including a number of protruded peaks for engaging with the membrane and for perforating the membrane.
- The element may be formed into or selected from a planar element, a longitudinal bar element, or a cylindrical element, and may include a bore formed in the cylindrical element for receiving or engaging with a shaft.
- A carrier may further be provided for supporting the element. The particles may be selected from silicon sands, or diamond sands, and may be selected from natural sands or synthetic sands.
- Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.

FIGS. 1-4 , a membrane perforatingdevice 1 in accordance with the present invention is shown inFIGS. 6-14 and is provided for engaging with a film ormembrane 20 and for perforating themembrane 20 or for forming a number ofperforations 21 in themembrane 20, and arranged for allowing the air to flow through themembrane 20 and for preventing the water to flow through themembrane 20, best shown inFIG. 4 . Themembrane 20 is to be attached or applied or engaged onto the outer or upper portion of a cup or receptacle orcontainer 30 which is provided for receiving the food orbeverage 31, in order to suitably seal thecontainer 30 and to preserve the food orbeverage 31. - In operation, as shown in
FIGS. 1 and 2 , thecontainer 30 and the food orbeverage 31 may be disposed in amicrowave oven 32 which may be provided for heating the food orbeverage 31 contained in thecontainer 30. After heating, a vapor may be generated within thecontainer 30 and may flow out through theperforations 21 of themembrane 20 for preventing thecontainer 30 from being exploded, and theperforations 21 of themembrane 20 are arranged for preventing the water from flowing out through theperforations 21 of themembrane 20 as shown inFIGS. 3 and 4 . The membrane perforatingdevice 1 in accordance with the present invention is thus provided for perforating themembrane 20 and for forming a number ofperforations 21 in themembrane 20. - As shown in
FIG. 5 , the membrane perforatingdevice 1 comprises a number of natural or synthetic silicon sands or diamond sands orparticles 10 each including a Mohr's hardness of about eight (8), and each including a number of pointed ends or tips or protrudedpeaks 11 for engaging with themembrane 20 and for perforating themembrane 20, and theparticles 10 may be secured together with such as powder metallurgy procedures, powder pressing procedures, sintering method, or with adhesive materials, for forming a spatial or three-dimension object or element, such as aplanar element 12 as shown inFIGS. 6 , 8, 10, alongitudinal bar element 13 as shown inFIGS. 7 , 9, acylindrical element 14 as shown inFIG. 11 , or acylindrical element 15 as shown inFIGS. 12-14 and having alongitudinal bore 16 formed therein for receiving a mandrel orshaft 17 and for allowing thecylindrical element 15 to be rotated together with the shaft 17 (FIG. 14 ). - As shown in
