Vacuum sealing devices are widely used for food preservation and storage and operate by evacuating air from a flexible bag such as a zipper bag, a profile bag, etc.
Conventional vacuum sealing devices generally include a vacuum and a sealing device, such as a bag welder that welds the bag opening shut. However, conventional vacuum sealing devices are prone to being ineffective in that air is often left inside the flexible bag, thereby failing to form a secure, air-tight seal. In addition, conventional vacuum sealing devices are typically bulky, heavy, and require the use of specialized equipment, containers, and/or bags, such as customized jars or single-use plastic bags that must be discarded after use.
Accordingly, what is needed is a vacuum apparatus that eliminates air from the bag to ensure a secure, airtight seal is formed and does not require the use of customized equipment, containers, and bags while also being portable, hand-held, and easy-to-use.
The disclosed hand-held vacuum sealing apparatus according to various aspects of the subject technology may comprise a cap comprising a siphon tube having a tapered surface and extending outwardly therefrom, a body portion releasably coupled to the cap, and a filter disposed between the cap and the body portion. The cap may comprise a first passage, wherein the siphon tube in combination with the first passage forms a first airflow path. The body portion may comprise a second passage forming a second airflow path, wherein the second airflow path in combination with the first airflow path forms a common airflow path when the body portion is coupled to the cap. The body portion may also comprise a suction assembly configured to draw air into the common airflow path, a perforated plate configured to be positioned against the filter, and an outlet for expelling the air.
A more complete understanding of the subject technology may be derived by referring to the detailed description and claims when considered in connection with the following illustrative figures. In the following figures, like reference numbers refer to similar elements and steps throughout the figures.
The subject technology may be described in terms of functional components. Such functional components may be realized by any number of components configured to perform the specified functions and achieve the various results. For example, the subject technology may employ various caps, body portions, filters, plates, perforations, siphon tubes, suction assemblies, motors, blades, batteries, and the like, which may carry out a variety of functions. In addition, the subject technology may be practiced in conjunction with any one of various enclosures, and the vacuum sealing apparatus described herein is merely one exemplary application for the technology.
Referring to
The cap 105 may comprise any suitable size or shape such as a cylindrical-shaped body or tubular-shaped body. In an embodiment, and when viewed from the top-down, the body of the cap 105 may be shaped in the form of a bird-beak, such as shown in
The cap 105 in combination with the siphon tube 107 may be shaped in the form of a narrow marquise diamond. In another embodiment, the cap 105 in combination with the siphon tube 107 may comprise a lanceolate-shaped body having ends that come to a point that fit neatly into an edge of the enclosure 102 and make it easier for the fingers of the user to create a tight fit around the siphon tube 107.
In one embodiment, the siphon tube 107 may be L-shaped. For example, and referring now to
In an embodiment, the first portion 109a and the second portion 109b may be integrated to form a single, monolithic siphon tube 107. Furthermore, the siphon tube 107 may be integrally coupled to the cap 105. In this regard, the siphon tube 107 and the cap 105 may form a monolithic structure.
The siphon tube 107 may be inserted into the enclosure 102 and positioned adjacent a left side or a right side of the enclosure 102 such that the second portion 109b is substantially parallel to a side of the enclosure 102.
According to various embodiments, the second portion 109b of the siphon tube 107 may be tapered along its longitudinal length. For example, in one embodiment, the diameter of the second portion 109b may increase along its length from the open end 108 to the cap 105. The second portion 109b may comprise a vesica piscis-shaped cross section. Because the second portion 109b may be tapered, once the enclosure 102 is substantially sealed around the second portion 109b, a user of the vacuum apparatus 100 may slowly slide the enclosure 102 down the second portion 109b while the vacuum apparatus 100 evacuates air from the enclosure 102.
In one embodiment, the cap 105 the cap further comprises an adjustable valve 118 for controlling the airflow rate within the common airflow path. The adjustable valve 118 may provide flexibility and adaptability, allowing users to fine-tune and customize the airflow according to their specific requirements. By incorporating such a valve, the functionality and performance of the cap may be enhanced, enabling users to have greater control over the airflow and optimizing the overall user experience.
The vacuum apparatus 100 may further comprise a locking component 120. The locking component 120 may comprise any suitable device or system for locking the cap 105 to the body portion 110. In one embodiment, the locking component 120 may be pivotal between a locked position wherein a movement of the cap 105 with respect to the body portion 110 may be constrained, and an unlocked position wherein the cap 105 may be disengaged from the body portion 110.
In an alternative embodiment, the locking component 120 may be configured to couple the cap 105 to the body portion 110 in a locked position, whereby the cap 105 is twisted into the locked position by pressing the cap 105 towards the body portion 110 and turning the cap 105 to lock into position. Similarly, the locking component 120 may decouple the cap 105 from the body portion 110 in an unlocked position, whereby the cap 105 is twisted into the unlocked position by turning the cap 105 to disengage. For example, the body portion 110 may comprise a positioning element 111 and external threads 113 on an outer surface 112 of the positioning element 111.
The positioning element 111 may be received in a notch (not shown) formed in the cap 105, and the external threads 113 may be in mating engagement with corresponding threads (not shown) formed on an inside of the cap 105, so that the cap 105 may be coupled to the body portion 110. The external threads 113 on the outer surface 112 of the positioning element 111 may be formed spirally and circumferentially on the outer surface 112.
The body portion 110 may comprise a second passage 116, which in combination with the first passage 106 forms an airway or air channel through the cap 105 and the body portion 110 to allow airflow from the open end 108 of the siphon tube 107 to an exhaust outlet 140 of the body portion 110.
In addition, the body portion 110 may comprise a perforated plate 125. The perforated plate 125 may comprise a plurality of perforations 127. The plurality of perforations 127 may be small enough to prevent debris from passing but not so small that air may not pass through. The perforated plate 125 may be detachably coupled to a top end 114 of the body portion 110 such that when the cap 105 is coupled to the top end 114, the perforated plate 125 may be positioned against the filter 115 so that the perforated plate 125 engages and supports the filter 115.
In another embodiment, the body portion 110 may comprise a second perforated plate (not shown). The second perforated plate may be coupled to an inner surface (not shown) of the cap 105. In addition, the second perforated plate may be positioned against a top end of the cap 105, such that the filter 115 may be disposed between the first perforated plate 125 and the second perforated plate when the cap 105 is coupled to the body portion 110.
The suction assembly 130 may comprise any suitable apparatus, system, or device capable of drawing air into airflow path B of the body portion 110. For example, in one embodiment, the suction assembly 130 may comprise a fan or blade 132, such as a turbine blade, and a motor 134 configured to draw air into the airflow path B. The blade 132 may be coupled to the motor 134, and the motor 134 may be electrically connected to a battery 135 for receiving power therefrom. The motor 134 turns the blade 132 to provide suction, drawing air into the siphon tube 107 and then through air flow path B prior exiting the body portion 110 via the exhaust outlet 140. In one embodiment, the motor 134 may be a variable speed motor for adjusting the suction power based on user preferences.
The battery 135 may be capable of supplying power to the vacuum sealing apparatus 100 and may comprise any suitable disposable, replaceable, or rechargeable battery, such as an alkaline battery, a lead acid battery, a nickel cadmium battery, a nickel metal hydride battery, a lithium-ion battery, and the like. It will be appreciated that modifications may be made to the battery 135 without departing from the scope of the subject technology. For example, instead of the battery 135, alternative energy sources, such as inductive, solar, and chemical energy sources, may be used to power the vacuum sealing apparatus 100. In one embodiment, the battery 135 may be isolated from the airflow path B. In an alternative embodiment, the battery 135 may not be isolated from the airflow path B, such that air may flow around the components of the vacuum sealing apparatus 100, exiting the body portion 110 at a bottom end thereof. The motor 134 and the battery 135 may or may not be isolated from the airflow path B.
The filter 115 may comprise any suitable filter capable of preventing or impeding contaminants, such as liquid, moisture, particles, debris, and the like that may be drawn into the cap 105 via the open end 108 of the siphon tube 107 from entering the body portion 110. The filter 115 may be disposed within the airflow path A and removably coupled to the cap 105 such that a user can periodically examine, clean and/or replace the filter 115 when needed. For example, the filter 115 may comprise a hydrophilic material, such as a sponge, and the like, that substantially impedes or prevents the passage of liquid or moisture therethrough. For example, the filter 115 may comprise a sponge or sponge-like material for capturing moisture or food particles that may be siphoned from the bag.
The filter 115 may comprise a plurality of perforations or narrow passageways that allow for the passage of air while impeding the flow of liquid, moisture, particles, and debris. In one embodiment, the filter 115 may be disposed within the siphon tube 107 or the body portion 110, independently or in combination with the cap 105. The filter 115 may be detachable for easy cleaning and replacement.
It will be appreciated that modifications may be made to the filter 115 without departing from the scope of the present invention. For example, the filter 115 as shown in
