Description

The present invention relates to an intake valve used for a compression bag or the like, and more specifically, a intake valve capable of performing an appropriate intake operation regardless of the shape of a suction nozzle such as a vacuum cleaner or a hose for suction. It is about a provided compression bag.

Conventionally, the degassing work of the compression bag was performed by covering the intake valve of the compression bag with the suction nozzle of the vacuum cleaner and the tip of the hose airtightly, but in recent years, various vacuum cleaners have been sold by various manufacturers. In some cases, the shape of the tip of the suction nozzle or hose is such that the intake valve cannot be airtightly covered. To solve this problem, the nozzle joint that airtightly joins the inner surface of the suction nozzle tip of the vacuum cleaner and the futon that covers the suction valve of the futon compression bag and is airtightly joined by pressing against the sheet of the futon compression bag. There was also an attachment for a futon compression bag composed of a compression bag joint (see Patent Document 1).

This attachment for a futon compression bag is configured so that the nozzle joint is airtightly joined to the inner surface of the suction nozzle tip of the vacuum cleaner, so that the suction nozzle tip of the vacuum cleaner is fitted to the nozzle joint. The nozzle joint and the tip of the suction nozzle can be easily and airtightly joined only by inserting the nozzle joint into the tip of the suction nozzle (simply insert the nozzle joint into the tip of the suction nozzle).

However, such an attachment for a futon compression bag needs to be attached every time suction is performed, and when suction is not performed, it needs to be stored separately from the bag, which makes suction and storage complicated.

Therefore, what the present invention attempts to solve in view of the above situation is to provide an intake valve capable of performing appropriate intake work regardless of the shape of the suction port of a vacuum cleaner or the like for suction, and a compression bag provided with the intake valve. It is in the point of providing.

In order to solve the above problems, the intake valve according to the present invention is provided on a valve body having an intake port capable of intake by a suction port such as a hose tip of a vacuum cleaner, and a part or all of the peripheral edge of the intake port. It is provided with a shape-variable portion that has no or almost no air permeability and is deformed in response to being pressed.

According to this configuration, it is possible to perform an appropriate intake operation regardless of the shape of the tip of the suction nozzle or hose of a vacuum cleaner or the like for suction.

Further, it is more preferable that the intake port is formed on the upper surface of the convex portion formed on the valve body.

According to this configuration, the convex portion is housed inside the tip of the hose or the like of the vacuum cleaner to perform the intake work, so that the hose or the like is less likely to shift from the intake valve and the intake work can be easily performed.

Further, the shape-variable portion may be provided over the entire peripheral edge of the convex portion.

According to this configuration, even if a part of the tip of the hose of the vacuum cleaner is protruding, the tip of the hose or the like is pressed against the intake valve to perform the intake work without particularly aligning in the circumferential direction. Can be done.

Furthermore, it is said that the member constituting the intake port is further provided with a suction prevention portion having a dimension of protruding outward from the inner diameter of the suction port at least when the suction port of the vacuum cleaner is brought into contact with the suction port. preferable.

According to this configuration, the members constituting the intake port are not accidentally sucked by the vacuum cleaner, and more appropriate intake work can be performed.

Furthermore, the shape-variable portion may be provided over substantially the entire upper surface of the suction prevention portion.

According to this configuration, it is possible to more reliably prevent the member forming the intake port from being accidentally sucked by the vacuum cleaner.

According to the intake valve according to the present invention, it is possible to perform an appropriate intake operation regardless of the shape of the tip of the suction nozzle or hose of a vacuum cleaner or the like for suction.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to the embodiments shown in the attached drawings, and includes all embodiments that satisfy the requirements described in the claims. ..

In the present specification, the intake port side of the intake valve and the compression bag is on the top, and the opposite side thereof is on the bottom. Further, the "intake port" refers to a hole or the like capable of sucking air inside the bag to the outside, and naturally includes not only one hole but also a large number of holes or a hole composed of a mesh shape. In such a case, the "periphery of the intake port" means the peripheral edge of a certain region formed by all or most of these holes and mesh portions. "Deforms in response to being pressed" means, for example, that when the hose of a vacuum cleaner is pressed against the convex tip, the pressed portion is pressed, that is, the convex tip. It means that it is dented into a similar shape and easily deformed. Further, the "suction port" of the vacuum cleaner means a portion of the tip that sucks when performing work using the vacuum cleaner, specifically, the tip of a hose, a nozzle, or the like.

First, the configurations of the compression bag 1 with an intake valve and the intake valve 6 according to the present embodiment will be described with reference to FIGS. 1 to 3.

As shown in FIG. 1, the compression bag 1 with an intake valve according to the present embodiment has a valve main body 7 having an intake port 9b capable of sucking air through a suction port of a vacuum cleaner, and a part of the peripheral edge of the intake port 9b or All of them are provided with a shape-variable portion 8 which has no or almost no air permeability and is deformed in response to being pressed.

Here, the compression bag 1 with an intake valve is described as being used as a compression bag for storing futons, clothes, etc. that are degassed by using a vacuum cleaner, but the present invention is not limited to this, and for example, it is not a vacuum cleaner. Other stored items may be stored using a dedicated air intake device, or the stored items may not be compressed. Further, the overall shape of the compression bag is not limited to the flat rectangular shape as shown in FIG. 1, but may be another shape such as a three-dimensional shape, and may be a box shape, a container shape, or the like. There may be.

The bag 2 is a bag body in which three sides of two rectangular sheets having a flat shape as a whole are crimped in a U shape to form an opening on the remaining one side, and a fastener 3 is provided in the opening. .. Therefore, by opening and closing the fastener 3, the stored items can be stored and taken out from the opening in the bag 2. Further, when the fastener 3 is closed, the bag 2 is in an airtight state, and except for the intake valve 6, there is almost no ventilation inside or outside the bag 2.

The fastener 3 is provided in the opening of the bag 2. The fastener 3 comprises an element 4 and a slider 5 movably provided along the element 4. The fastener 3 is a general one, and the opening of the bag 2 is opened by moving the fastener 3 from one end to the other end along the element 4, and the opening of the bag 2 is opened by moving the fastener 3 in the opposite direction. It will be closed. The fastener 3 is not limited to the configuration as shown in the drawing, and is any sealing means capable of closing the bag after storing the stored items and sealing the inside of the bag to the extent that intake air is taken from the intake valve 6. , Other configurations may be used. For example, by providing a simple heat-sealable portion in the entire area of the opening, it is possible to heat the stored items with an iron to seal them. However, with such a configuration, the configuration can be made simpler and can be manufactured at low cost.

As shown in FIG. 2, the intake valve 6 is made of a hard resin in which a shape-changing portion 8 formed in an annular shape is provided on the valve main body 7. The shape variable portion 8 is adhered and fixed to the peripheral edge of the disk-shaped convex portion 9a on the upper surface of the valve body 7. Here, the upper surface of the shape variable portion 8 is located above the upper surface of the valve body 7. With this configuration, during the intake work, the tip of the hose N of the vacuum cleaner surely contacts the shape variable portion 8 and the shape variable portion 8 is deformed, so that the vacuum cleaner and the intake valve 6 are properly airtight. can do.

The valve body 7 is composed of a main body upper portion 9, a valve body holding portion 10, a valve body 11, and a main body lower portion 12 in this order from the top. With these configurations, the valve body 7 can be pressurized and ventilated from the inside to the outside of the bag 2, but cannot be ventilated from the outside to the inside. As described above, the configuration related to the valve function of the valve body 7 is described as an example, but the valve body 7 adopted in the present invention is not limited to this configuration, and is not limited to this configuration, and is not limited to this configuration. It can be widely adopted regardless of the product, its use and function.

An intake port 9b is formed on the upper side of the valve body 7 (opposite the adhesive surface of the bag 2). The intake port 9b is composed of a plurality of small holes inside a circular shape having a constant diameter so as to fit inside the tip shape of the hose N of the vacuum cleaner.

Further, on the upper side of the valve body 7, a step portion is formed because a part of the valve body 7 is formed slightly lower than the intake port 9b. By providing the shape variable portion 8 on this step portion, problems such as the shape variable portion 8 being displaced during use are unlikely to occur. Further, since this step portion is specifically formed in a circular shape, the tip of the hose of the vacuum cleaner is easily fitted and is not easily displaced. In addition, this step portion may be formed by a partial recess.

The shape variable portion 8 is configured to be recessed according to the shape of the tip of the hose N by being brought into contact with the tip of the hose N. Therefore, no matter what shape the tip of the hose N has, no gap is created between the tip of the hose N and the tip of the abutted hose N, and the hose N and the intake valve 6 can be held in an airtight state. ing. Further, the shape variable portion 8 is made of foamed resin and can be constructed at low cost, but it may be made of another elastic body or the like. Furthermore, since the shape variable portion 8 is provided as a part of the valve body 7, a simple configuration with higher durability can be adopted, but the present invention is not limited to this, for example. , It may be attached to a general valve body 7 as a separate member later, and by commercializing it as such an attachment, it can be easily applied to a conventional product. Here, the shape variable portion 8 is made of a member having no air permeability, so that the hose N and the intake valve are highly airtight, but this air permeability is not necessarily provided at all. It is not necessary, for example, it has almost no airtightness, and although the bag 2 can be sufficiently inhaled by the suction of the vacuum cleaner, it may be slightly airtight and have a certain degree of airtightness. With such a configuration, the burden on the vacuum cleaner due to the suction work can be reduced.

Hereinafter, a specific configuration of the valve body 7 will be described.

The upper portion 9 of the main body constituting the upper surface side of the valve main body 7 has a circular shape as a whole, and is provided with a convex portion 9a whose central portion projects upward. An intake port 9b is formed on the upper surface of the convex portion 9a. The intake port 9b is composed of a plurality of arcuate small holes extending concentrically, and the air permeability in the vertical direction is ensured by these. Further, the convex portion 9a is formed in a low columnar shape, and since this diameter is about 35 mm, it is slightly smaller than the inner diameter of the hose of a general vacuum cleaner, and when actually performing the degassing work, the convex portion 9a is formed. The hose is pressed against the intake valve 6 so that the convex portion is located inside the hose, and the work is performed.

The peripheral edge of the intake port 9b of the upper part 9 of the main body is lowered by one step, and a suction prevention portion 9c is provided. Since the suction prevention portion 9c is integrally formed with the main body upper portion 9 which is a member forming the intake port 9b of the intake valve, only the main body upper portion 9 is erroneously sucked by the vacuum cleaner during the intake work. Can be prevented. Further, since the suction prevention portion 9c also functions to sandwich the lower portion 12 of the main body and the bag 2, it is possible to efficiently obtain a highly durable product. Although the suction prevention portion 9c has a simple structure by being formed in a disk shape, the bag 2 can be reliably held, and the force due to this holding on the bag 2 can be dispersed, so that the bag 2 can be formed. Although the structure is such that it will not be torn unexpectedly, the shape of the suction prevention portion 9c is not limited to such a shape. The minimum configuration may be used and the manufacturing cost may be low. Further, it is of course possible to further reduce the manufacturing cost by the configuration in which the suction prevention portion 9c does not exist.

The lower portion 12 of the main body is provided with a recess and a vent into which the valve body 11 is fitted. Although these configurations are general, they are not essential configurations in the present embodiment and are the same as a whole. Of course, other configurations may be used as long as they are configured to obtain the action of. An annular flat portion is formed on the upper side of the lower portion 12 of the main body, and the flat portion and the lower surface of the upper portion 9 of the main body securely hold the bag 2.

FIG. 3 shows the configuration of the intake valve 6 of the present embodiment and the intake valve 6A according to another embodiment.

As shown in FIG. 3A, the intake valve 6 includes an annular shape variable portion 8 as described above, and with such a configuration, the convex portion Na at the tip of the hose N of the vacuum cleaner. The shape of the shape variable portion 8 is changed according to the tip shape of the hose N including the convex portion Na regardless of where the hose N is located in the circumferential direction, and the hose N and the intake valve 6 are communicated in an airtight state.

On the other hand, as shown in FIG. 3B, the intake valve 6A is provided with a shape-changing portion 8A on a part of the peripheral edge of the intake port 9b, and with such a configuration, the tip of the hose N of the vacuum cleaner is provided. By aligning the position of the convex portion Na in the circumferential direction with the shape variable portion 8A and bringing the tip of the hose N into contact with the intake valve 6A, the shape of only the shape variable portion 8A is changed to the inside of the hose N. The intake valve 6A is communicated with the intake valve 6A in an airtight state. The other configurations of the intake valve 6A are the same as those of the intake valve 6, and the description thereof will be omitted.

Next, an intake method using the intake valve 6 will be described along with FIGS. 4 and 5.

First, a futon, clothes, etc. are stored in the bag 2 and the opening of the bag 2 is closed. If the stored items are futons, clothes, etc., the size of the stored items themselves can be reduced by degassing, and the overall bulk can be reduced, so it is the most useful, but the bulk does not decrease. May be used for items that are simply stored in a sealed state or in a substantially vacuum state for the purpose of long-term storage.

Second, as shown in FIG. 4, the tip of the hose N of the vacuum cleaner comes into contact with the intake valve 6. At this time, it is necessary that the opening of the hose N comes into contact with the intake valve 6 so as to cover all of the intake ports 9b. Further, at the time of this contact, if the convex portion Na is present at the tip of the hose N of the vacuum cleaner, the hose N is positioned so that the convex portion Na hits the shape variable portion 8. By contacting the hose N with the intake valve 6 in this way, as shown in FIG. 5, the shape of the shape variable portion 8 changes according to the tip shape of the hose N, and the hose N and the intake valve 6 are in an airtight state. It will be retained.

Finally, the air in the bag 2 is sucked by the intake air of the vacuum cleaner, and after the intake is completed, the hose N of the vacuum cleaner is pulled away from the intake valve 6, and the intake operation is completed. At this time, due to the action of the valve body 11 and the like of the intake valve 6, the outside air does not flow into the bag 2, and the bag can be stored in a small volume. In order to take out the stored items, the bag 2 may be opened by using a fastener 3 or the like, and by this operation, air naturally flows into the bag 2 and the stored items can be taken out.

In the above description, one bag is provided with one intake valve, but the compression bag is not limited to such a configuration, and one bag is provided with a plurality of intake valves. It may be. Further, the intake work is not limited to the one using the hose of the vacuum cleaner, any one can be used as long as it intakes air, and one tip of the nozzle or the like which is the contact portion with the intake valve is used. It is not limited to the convex portion, but may be a concave portion or one in which both of these are formed.
