Description

TECHNICAL FIELD

[0001] The utility model relates to the field of beverage container, especially a straw type emptyable beverage container. BACKGROUND

[0002] The conventional containers for storing beverages, such as juice bottles, wine bottles and milk bottles, have a whole bottle body with a liquid outlet only at the top. For example, when a baby needs to drink milk, the baby holds the nipple of the milk bottle and tilts the bottle to suck out the milk. However, the conventional nipple is easy to let air in, and the milk is easy to deteriorate after long time contact with air and bacteria. In addition, when the beverage is paste or cream, it is difficult to suck out from the bottle by the suction of the mouth due to its low fluidity. SUMMARY

[0003] The utility model aims to provide a straw type emptyable beverage container, which can avoid the contact between air and beverage in the bottle body, prevent the beverage from deteriorating rapidly, and keep the taste and mouthfeel of the beverage.

[0004] To achieve the above-mentioned purpose, the utility model provides a straw type emptyable beverage container, which comprises a bottle body with an opening at the top and a bottle bottom at the bottom, a piston arranged in the inner cavity of the bottle body, the piston being in close contact and sliding fit with the inner side wall of the bottle body, and a through hole arranged in the middle of the piston; the utility model also comprises a straw, the upper end of the straw extending upward out of the opening of the bottle body, and the lower end of the straw being in communication with the lower part of the piston through the through hole.

[0005] As a further improvement of the utility model, the through hole of the piston and the straw are in sealing sliding fit, and the lower end of the straw is located at the bottom of the inner cavity of the bottle body.

[0006] As a further improvement of the utility model, a first limiting block capable of holding the piston is arranged on the outer side wall of the lower end of the straw.

[0007] As a further improvement of the utility model, a groove for the first limiting block to move into is arranged in the middle of the bottom surface of the piston.

[0008] As a further improvement of the utility model, the piston and the straw are fixed relative to each other; and the straw and the opening of the bottle body are in relative sliding fit.

[0009] As a further improvement of the utility model, at least one sealing ring protruding part is arranged on the outer side wall of the piston.

[0010] Advantages

[0011] Compared with the prior art, the straw type emptyable beverage container of the utility model has the following advantages:

[0012] 1. As the drink in the bottle flows out of the straw, the piston slides down along the bottle under the action of atmospheric pressure, preventing air from coming into contact with the drink in the bottle, thus preventing the drink from quickly spoiling and preserving its taste and mouthfeel. When the drink container is used as a feeding bottle and an infant is feeding from the bottle, the infant cannot blow air into the bottle through the nipple to prevent the milk from quickly spoiling due to contact with air. Furthermore, there is no air in the bottle, preventing the infant from experiencing bloating due to inhaling air.

[0013] 2. When the straw and the piston are relatively fixed, pressing the piston downward by operating the straw will help paste-like and paste-like drinks that are not easy to flow to flow out from the upper end of the straw.

[0014] The present invention will become more clear through the following description in conjunction with the accompanying drawings, which are used to explain embodiments of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0020] Example 1

[0021] The specific implementation of the utility model is as follows Figs. 1 to 3 As shown, a straw-type emptyable beverage container includes a bottle body 1 with an opening at the top and a bottom. A piston 2 made of an elastic material is disposed within the inner cavity of the bottle body 1. The piston 2 is in close contact with and slidably engages the inner sidewall of the bottle body 1. A through hole 23 is defined in the center of the piston 2. The beverage container also includes a straw 8. The upper end of the straw 8 extends upwardly beyond the opening of the bottle body 1. The lower end of the straw 8 communicates with the lower portion of the piston 2 through the through hole 23. In this embodiment, the piston 2 can be made of an elastic material.

[0022] The outer side wall of the piston 2 is provided with at least one sealing ring protrusion 21. In this embodiment, the outer side wall of the piston 2 is provided with three sealing ring protrusions 21 arranged from top to bottom. The more the number of the sealing ring protrusions 21, the better the sealing effect.

[0023] The lower end of the straw 8 is provided with an inclined opening 82, which is beneficial to sucking out the liquid at the bottom of the bottle body 1 through the straw 8.

[0024] The opening at the top of the bottle body 1 is detachably connected with the bottle top cover 5 through threads. The middle of the bottle top cover 5 is provided with a second through hole 52, and the straw 8 penetrates through the middle of the bottle top cover 5 from the second through hole 52. In addition, the bottle top cover 5 can be provided with a vent hole, which ensures that the external air can enter the bottle body 1 and be located above the piston 2, so that the top of the piston 2 can be affected by the atmospheric pressure. There can also be a gap between the second through hole 52 of the bottle top cover 5 and the straw 8 for air to pass through.

[0025] In this embodiment, the through hole 23 of the piston 2 and the straw 8 are in sealing sliding fit, and the lower end of the straw 8 is located at the bottom of the inner cavity of the bottle body 1. The straw 8 and the bottle top cover 5 do not slide relative to each other, and specifically, a second limiting block 81 can be arranged on the side wall of the straw 8, which is located below the bottle top cover 5 and is used to prevent the straw 8 from being pulled out of the middle of the bottle top cover 5 upward. In this mode, the through hole 23 in the middle of the piston 2 and the straw 8 are in close sliding fit, and when the piston 2 moves up and down along the straw 8, the liquid located below the piston 2 will not pass through the through hole 23 and the straw 8 upward.

[0026] When the user sucks the straw 8 from the top of the straw, the beverage at the bottom of the inner cavity of the bottle body 1 is sucked out through negative pressure, and as the beverage in the bottle body 1 decreases, the piston 2 also gradually moves downward until it reaches the bottom of the bottle body 1. The outer side wall of the lower end of the straw 8 is provided with a first limiting block 83 capable of supporting the piston 2, and when it is necessary to detach the piston 2 from the bottle body 1, the bottle top cover 5 is unscrewed, and the piston 2 can be pulled out by pulling the straw 8 upward. The middle of the bottom surface of the piston 2 is provided with a groove 22 for the first limiting block 83 to move into, and when the bottom of the piston 2 moves to be attached to the bottom of the inner cavity of the bottle body 1, the first limiting block 83 of the straw 8 is located in the groove 22 of the piston 2. This structure can ensure that the beverage in the bottle body 1 is basically sucked out, reducing waste.

[0027] Embodiment 2

[0028] Different from the embodiment 1, the piston 2 and the suction pipe 8 are relatively fixed, the suction pipe 8 and the bottle top cover 5 of the bottle body 1 opening are relatively sliding, and specifically the piston 2 and the suction pipe 8 are fixedly connected. The structure is mainly aimed at paste, paste and other not easy to flow drinks. When the user needs to drink the drink, the suction pipe 8 is pinched by the fingers, and is pressed downward relative to the bottle body 1, drives the piston 2 to press the paste, paste drink in the bottle body 1 downward, and at this time the paste, paste drink can overflow from the top of the suction pipe 8. In addition, when the piston 2 and the suction pipe 8 are relatively fixed, the bottle top cover 5 can also be cancelled.

[0029] The utility model has been described above in combination with the best embodiment, but the utility model is not limited to the above disclosed embodiments, and should cover various modifications, equivalent combinations according to the essence of the utility model.
