Membrane perforating device
A perforating device for perforating a membrane includes a three-dimension element having a number of particles secured together with such as powder metallurgy procedures, powder pressing procedures, sintering method, or with adhesive materials, and the particles each include 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 engaging with a carrier. The particles may be selected from silicon sands, or diamond sands, and may be selected from natural sands or synthetic sands.
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.
SUMMARY OF THE INVENTIONThe 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.
Referring to the drawings, and initially to
In operation, as shown in
As shown in
As shown in
Alternatively, as shown in
It is to be noted that the elements 12, 13, 14, 15 of the membrane perforating device 1 are formed or made of a number of silicon sands or diamond sands or particles 10 each including a number of pointed ends or tips or protruded peaks 11 for engaging with the membrane 20 and for perforating the membrane 20, and for allowing the membrane 20 to be suitably perforated with the elements 12-15 of the membrane perforating device 1. The particles 10 may be selected from natural or synthetic silicon sands or diamond sands. The elements 12-15 of the membrane perforating device 1 include a great Mohr's hardness of about eight (8) and will not be rusted.
Again, as shown in
Accordingly, the membrane perforating device in accordance with the present invention may be 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.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
