Description

Vacuum packaging container

The invention relates to a vacuum packaging container. Background technique

In the chemical industry, some contents do not wish to be in contact with air, so vacuum packaging containers are required for packaging. There are two main types of existing vacuum packaging containers, namely "bottom piston type" and "bottom bag type".

As shown in Figs. 1A and 1B, the bottom piston type vacuum packaging container mainly includes a cover 1, a lotion pump 2, a piston 3, and a bottle 4. The cover 1 is overlaid on the lotion pump 2. The lotion pump 2 does not have a venting hole for balancing the air pressure, so that no air is introduced into the bottle 4. The piston 3 is disposed in the bottle 4 and is movable up and down within the bottle 4. A vent hole (not shown) is provided at the bottom of the bottle 4. When working, the emulsion in the bottle can be aspirated by simply pressing the lotion pump 2 by hand. During the suction, since the vent hole is provided at the bottom of the bottle 4, there is atmospheric pressure below the piston 3, so that the piston 3 is pressed and moved upward. Thus, it is ensured that the emulsion is not in contact with the air, and that no vacuum is present in the emulsion above the piston 3 in the bottle 4.

In such a bottom piston type vacuum packaging container, although vacuum packaging can be realized, there are still many problems. The first is that the accuracy of the components is very high. The piston 3 is slidably engaged with the inner wall of the bottle 4. If the fit between the two is too loose, it may cause leakage. If the fit between the two is too tight, the piston 3 may not move upward. In the latter case, a vacuum may occur above the piston 3, which may not be able to extract or completely absorb the emulsion. Further, since the suction force generated by the lotion pump 2 is required to compensate the weight of the emulsion and the piston 3 and the friction between the piston 3 and the bottle 4, the sucking force for extracting the emulsion is very small. From this point of view, it is also easy to cause problems that cannot be extracted or difficult to completely absorb the emulsion. 3⁄4, this vacuum packaging container is prone to leakage when the contents are thin or the bottle is pressurized.

The built-in bag type vacuum packaging container mainly includes a cover, a lotion pump, a pouch and a bottle. The cover, the nipple pump and the bottle are all similar to the bottom piston vacuum packaging container described above. The main difference between the built-in bag vacuum 3⁄4 container and the bottom piston vacuum packaging container described above is that a soft pouch is used to hold the emulsion. The pouch is placed in a bottle, and the pouch of the pouch is sandwiched between the lotion pump and the mouth of the bottle. When E is used, the emulsion in the bottle can be aspirated by pressing the lotion pump by hand. During the suction process, a vent hole is provided at the bottom of the bottle by f ¹ , so there is atmospheric pressure on the outside of the bag, thereby sac The emulsion in the pump is pumped out and the volume of the pouch is getting smaller and smaller. Thus, it is ensured that the emulsion does not come into contact with the gas, and that no vacuum occurs in the emulsion in the pouch. '

The built-in bag type vacuum packaging container is easier to extract the emulsion than the bottom piston type vacuum container described above, and the precision of the parts is not high. However, when such a vacuum packaging container is employed, it is difficult to put the pouch into the bottle. In addition, there may be a small amount of air in the upper portion of the pouch due to insufficient filling, which makes it difficult to extract the emulsion and cause the air to come into contact with the emulsion. In addition, the mouth of the pouch is small and the filling is not convenient. A further problem is that a straw can be optionally placed on the lotion pump, but the opening at the end of the straw is easily clogged, resulting in a problem of inability to extract or to completely absorb the emulsion. Summary of the invention

In order to overcome the above drawbacks, an object of the present invention is to provide a vacuum packaging container which has high suction ability, no leakage, and low cost.

To achieve the above object, the present invention provides a vacuum packaging container comprising: a bottle body having a top, a bottom and a side wall, and provided with a venting hole; a lotion pump mounted on the top of the bottle body; The vacuum packaging container further includes at least one pocket, the periphery of the bladder being sealingly bonded to the inner wall of the body such that one side of the bladder contacts the emulsion and the other side is in communication with the atmosphere. .

Preferably, a guide strip is further included, the guide strip being attached to the feed port of the lotion pump, the guide strip being shaped to have at least one open guide groove.

Preferably, the guide strip is a thin strip and the shape of the guide strip is a cross section having a generally "ten" shape.

Preferably, the guide strip includes a guide head having the same structure as the guide strip but having a length smaller than the guide strip, the guide head being attached to the head of the conventional straw. Preferably, the guide strip has a lateral guiding structure.

Preferably, the bladder has an open first end and a closed second end, the outer side of the open first end being bonded to the inner wall of the top of the bottle.

Preferably, the bladder has an open first end and a closed second end, the outer side of the open first end being bonded to the inner wall of the bottom of the bottle.

Preferably, the bladder is stretched in the longitudinal or transverse direction of the body and the venting opening is provided in the bottom of the body.

Preferably, the pouch is a folded pouch. Preferably, the base and the body are separate components.

In the vacuum packaging container of the present invention, the suction generated by the lotion pump is substantially all used for pumping the emulsion without offsetting the weight of the emulsion and the piston and the friction between the piston and the wall of the bottle. Therefore, such a vacuum packaging container has a strong suction force and can overcome the problem that it is impossible to extract or to completely absorb the emulsion. The vacuum packaging container of the present invention also has the advantages of low manufacturing precision and low cost. Further, since the bottle mouth for filling is large and the bag has been placed in the bottle before filling, the vacuum packaging container of the present invention has an advantage of being easy to fill.

In addition, because of the unique guide strips, it is ensured that no blockages will occur under all conditions. Moreover, when a small amount of air remains in the upper portion of the bladder during filling, the residual air can be absorbed at the junction of the emulsion pump and the guide strip. Even when the lotion pump is turned upside down, the emulsion can be smoothly withdrawn. In the vacuum packaging containers with or without the use of straws, it is impossible to achieve the above effects. DRAWINGS

detailed description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, wherein like reference numerals refer to the

Referring to Figures 2A to 2C, there is shown a vacuum packaging container 10 in accordance with a first embodiment of the present invention. The vacuum packaging container 10 comprises: a bottle body 7 having an open top 71 and a bottom 72, and is provided with a base 73 closing the bottom, a venting hole in the base 73; and a lotion pump 2 mounted on the top of the bottle body 71, and does not have a venting hole for balancing air pressure; a cover 1 covering the lotion pump 2; a bag 5 having an open first end 51 and a closed second end 52, the first end 51 of which Sealedly coupled to the top 71 of the bottle body; and a guide strip 6, which is attached to the feed port of the lotion pump 2 like a conventional straw.

In the first embodiment, the outer side of the open first end 51 of the pouch 5 is bonded to the inner wall of the top portion 71 of the bottle body 7, thereby sealingly bonding the pouch 5 to the inner wall of the bottle body 7. In this case, one side of the pouch 5 is in contact with the emulsion while the other side is in communication with the atmosphere. The sealing of the bladder 5 with the bottle 7 prevents leakage, thereby preventing the emulsion from coming into contact with the air and the emulsion pump not working properly.

The guide strip 6 is a thin strip made of plastic. In this embodiment, the guide strip 6 has a cross section of a substantially "ten" shape. In other words, the guide strip 6 has four projections 61, and four open guide grooves 62 are formed between the adjacent projections 61. With the guide strip 6, the sucked emulsion A can enter the guide groove 62 from any position in the longitudinal direction of the guide strip 6, and enter the emulsion pump 2 upward along the guide groove 62, not at the end like a normal straw. The mouth of the mouth is blocked. In addition, when a small amount of air remains in the upper portion of the pouch during filling, the residual air can be sucked out at the junction of the lotion pump 2 and the guide strip 6 by means of the guide strip 6. In addition, even when the lotion pump is inverted, the emulsion can be smoothly withdrawn as well. Further, even if the pouch 5 is adsorbed on the guide strip 6, the pouch 5 and the guide strip 6 form a liquid passage similar to the straw, which does not affect the extraction of the emulsion. In the vacuum packaging containers with or without the use of straws, it is impossible to achieve the above effects.

Although the guide strip 6 having a substantially "ten" cross section is shown in the first embodiment and the second and third embodiments below, it should be understood that the shape of the guide strip is not limited thereto, for example, Pick Three or other numbers of protrusions are taken to define a corresponding number of guide slots, and the slots can be directly slotted. In summary, as long as the shape of the guide strip is such that it has at least one open guide groove, the emulsion can be smoothly introduced into the pump. Further, as shown in Fig. 6, the above-described guide strip may include a guide head 6a. The guide head 6a has the same structure as the guide strip, but has a smaller length than the guide strip. The guide head 6a can be attached to the head of a conventional straw. The guide head can prevent clogging of the pipette head by having a guide groove similar to the guide bar. Further, a zigzag-shaped lateral guiding structure 610a, which can facilitate guiding the lateral flow of the emulsion along the guiding head 6a, can be formed on the projection 61a of the guiding head 6a. It should be understood that the guiding structure 610a is equally applicable to the guide strips 6 described above.

For the vacuum packaging container of this embodiment, the emulsion A is injected from the open first end 51 of the pouch 5 at the time of filling. At this time, the emulsion A is accommodated in the pouch 5. Emulsion A expands the pouch 5 to its maximum volume and fills the inside of the bottle (see Figure 2A). As the emulsion is continuously withdrawn, the pocket 5 gradually becomes smaller until the volume is substantially zero (see Figure 2B).

Referring to Figures 3A to 3C, there is shown a vacuum packaging container 20 in accordance with a second embodiment of the present invention. As shown in Fig. 3C, the vacuum packaging container 20 of this embodiment differs from the first embodiment described above in that the open first end 51 of the bag 5 is sealingly coupled to the bottom 72 of the bottle body 7. Specifically, the outer side of the open first end 51 of the pouch 5 is bonded to the inner wall of the bottom portion 72 of the bottle body 7, thereby sealingly bonding the pouch 5 to the bottle body 7. In this embodiment, as in the first embodiment described above, one side of the pouch 5 is in contact with the emulsion while the other side is in communication with the atmosphere.

For the vacuum packaging container of this embodiment, the emulsion A is injected from the closed second end 52 of the pouch 5 during filling. At this time, the emulsion A comes into contact with the inner wall of the bottle 7, and the bladder 5 is compressed to the minimum (see Fig. 3A). In other words, in this case, the pouch 5 serves as the "bottom of the container" in contact with the emulsion. As the emulsion is continuously withdrawn, the bladder 5 is gradually raised until the emulsion is substantially emptied (see Figure 3B).

Referring to Figures 4A to 4C, there is shown a vacuum packaging container 30 in accordance with a third embodiment of the present invention. The vacuum packaging container 30 of this embodiment differs from the above two embodiments in that a bellows-like longitudinally folded pocket 5a is employed. This longitudinally folded bladder 5a is also used to hold the emulsion (see Figure 4A) and is contracted upwardly along the longitudinal direction of the body as the emulsion is withdrawn until the volume is substantially zero (see Figure 4B).

Referring to Figures 5A and 5B, there is shown a vacuum packaging container 40 in accordance with a fourth embodiment of the present invention. The main difference between the vacuum packaging container 40 of this embodiment and the above three embodiments is that two pockets 5b are employed. The pouch 5b is disposed along the longitudinal direction of the bottle body, and its peripheral edge is sealingly coupled to the bottom of the bottle body. In addition, A venting hole 74 is provided on the bottom wall.

The emulsion is contained between the two pockets 5b. As the emulsion is continuously withdrawn, the pouch 5b is gradually enlarged until the emulsion is substantially evacuated (see Fig. 5B).

While the vacuum packaging container of the present invention has been described in detail above in connection with the preferred embodiments, those skilled in the art should be able to make various equivalent modifications and changes in the above. For example, the pouch may also be in the form of a lateral fold that contracts in the transverse direction of the bottle; the base 73 may be a member formed separately from the body 7 as described above, but may also be formed integrally with the bottle 7; The cover 1 is not an essential component and can also be omitted; the sealing combination of the bag and the bottle body can be combined with hot pressing or the like in addition to the bonding; the bag can be used in addition to one or two, as needed. More than one; the lateral guiding structure of the guiding strip may adopt other shapes that facilitate the lateral flow of the emulsion in addition to the zigzag structure. Therefore, the scope of the present invention is not limited to the embodiments described above, but is defined by the appended claims.
