Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box for fluids. Background Art

[0002] Fluid substances, such as toothpaste and cosmetics, have special requirements for packaging materials due to their special physical properties, such as fluidity, volatility, and possible organic solvents. Usually, for the convenience of users, plastic shell packaging is adopted, which is convenient for users to squeeze out and use directly. However, the use of plastic shell packaging is not beautiful, and it is squeezed and deformed in the bag, and it is easy to overflow from the port, contaminating the cosmetics and reducing the user's sensory experience. Secondly, when the plastic shell is used as a toothpaste packaging carrier, when the plastic shell is directly squeezed out, both hands are required to squeeze the toothpaste onto the toothbrush, which is not very convenient to use, and it is not easy to squeeze out the toothpaste completely, resulting in a certain amount of waste, so it needs to be improved.

[0005] Preferably, a stopper is detachably mounted at the discharge port of the discharge pipe.

[0006] Preferably, a stop bar is provided in the discharge pipe, and the stop bar abuts against the outer ring of the second one-way valve.

[0007] Preferably, a stop ring is provided on the outer side of the top of the soft capsule, and the feed port of the discharge pipe abuts against the stop ring.

[0008] Preferably, a finger pressing position is provided on the top of the pressure head.

[0013] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will结合附图对本实用新型的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本实用新型。但是本实用新型能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本实用新型内涵的情况下做类似改进,因此本实用新型不受下面公开的具体实施例的限制。

[0014] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manners.

[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0016] Such as Figures 1 to 3 It should be noted that there is an incomplete sentence in the original text at ID=10. The translated text is provided based on the existing content as accurately as possible.As shown, a fluid packaging box includes a lid 1, a box body 2, a shoulder sleeve 3, a pressure head 4, and a soft bladder 5. The bottom of the box body 2 is provided with an air hole 21, the box body 2 is provided with a piston 6, the shoulder sleeve 3 is mounted on the open end of the box body 2, the soft bladder 5 is mounted in the shoulder sleeve 3, the bottom of the soft bladder 5 is provided with a first one-way valve 51, the top of the soft bladder 5 is inserted into the discharge pipe 41 of the pressure head 4, the pressure head 4 is detachably connected to the shoulder sleeve 3, and the discharge pipe 41 is installed with a second one-way valve 42. The discharge pipe 41 is connected to the box body 2 through the soft bladder 5. The box lid 1 covers the pressure head 4 and is engaged with the outer wall of the shoulder sleeve 3. Specifically, in this embodiment, the box body 2 is cylindrical. In other embodiments, it can also be designed as other shapes such as square or oval, which are not specifically limited here. The box body 2 is made of metal or plastic and is equipped with a piston 6. The piston 6 can move along the inner wall of the box body 2. When the user needs to squeeze out a material, such as toothpaste, the user can operate it with one hand and directly press the pressure head 4. The pressure head 4 is forced down, causing the soft capsule 5 to be deformed under pressure, and the gas inside the soft capsule 5 is discharged, forming a negative pressure state. At this time, due to the presence of the air hole 21 at the bottom of the box body 2, under the action of atmospheric pressure, the piston 6 can be driven to move upward, and then the material is squeezed out from the box body 2 into the soft capsule 5. It is understandable that in order to prevent the material from flowing back, we install a first one-way valve 51 at the bottom of the soft capsule 5. When the soft capsule 5 is full of material, the material overflows from the cross opening at the top of the soft capsule 5 into the discharge pipe 41, and passes through the second one-way valve 42 and is discharged. The entire operation is extremely smooth and can be operated with one hand. The presence of the first one-way valve 51 and the second one-way valve 42 can prevent the material from flowing back, and the user experience is excellent.

[0017] like Figures 2-3 As shown, a plug 43 is detachably installed at the discharge port of the discharge pipe 41. When the material needs to be extruded, the plug 43 is removed. After completion, the plug 43 is re-plugged to prevent air from entering and prevent the discharge pipe 41 from being contaminated.

[0018] like Figure 3 As shown, a stop bar 411 is provided in the discharge pipe 41, and the stop bar 411 abuts against the outer ring of the second one-way valve 42. Specifically, the stop bar 411 limits the upward movement of the second one-way valve 42, preventing the one-way valve 42 from being flushed out of the discharge pipe 41 by the fluid.

[0019] like Figure 3 As shown, a stop ring 52 is provided on the outer side of the top of the soft bag 5, and the inlet of the discharge pipe 41 is in contact with the stop ring 52. The stop ring 52 is used to prevent the soft bag 5, which is small at the top and large at the bottom, from being mostly inserted into the discharge pipe 41 in a pagoda shape, thereby playing a limiting role and ensuring the telescopic performance of the soft bag 5.

[0020] like Figures 2-3As shown, a pressing finger position 44 is provided on the top of the pressure head 4, which is convenient for the user to apply a force on the pressing finger position 44 to increase friction and prevent slipping.

[0021] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
